Description

shorts

technical field

The present invention relates to a pair of shorts for wearing a sanitary napkin on the crotch, and more particularly to a pair of shorts which can securely hold a thick sanitary napkin used at night to prevent shifting, have an excellent fit, and cause substantially no restraint to the wearer An uncomfortable feeling in the body.

Background technique

There is a need for a pant to reliably and securely retain a sanitary napkin attached to the crotch portion of the pant, to prevent displacement of the napkin in the crotch, and to provide comfort to the wearer by reducing penetration into the crotch of the body. Feel.

As this type of shorts, there is disclosed (in JP-2001-522958A ) that has a portion having a large tensile load bearing capacity in the central region between the front and the rear, located between the front and the rear. Between the rear and connecting the front and rear crotch section, and a pair of leg elastic openings. Such shorts have a longitudinal stretch-controlling member disposed in the crotch region and several stretch-controlling members located in the front and rear and extending from the longitudinal stretch-controlling member to the waistband. The inventors of the present invention provide a comfortable underpants which can easily fit a sanitary napkin in the crotch and prevent the sanitary napkin from getting into the crotch (JP-A-2002-660). Such shorts include a waistband around the waist opening and leg bands around the leg openings, and a crotch serving as a portion for attaching the sanitary napkin. The shorts are characterized in that, when the size is measured under the condition of three-dimensional shape when worn, if the central height length is 100, the central length from the crotch to the waist opening part is the same as the length from the leg opening to the waist opening part The size ratio between the side lengths is that the side height length is in the range of 80-200, and an elastic lifting part is set in the rear part from the crotch to the waist opening.

But according to the shorts disclosed in JP-T-2001-522958, although the sanitary napkin placed in the crotch area can be firmly installed on the body through the stretch control part, since the stretch control part is set as a narrow strip, the effect Force is concentrated at a linear point, so the shorts may dig into the body in worn conditions. In addition, the sanitary napkin may be curved at the center to form an upward bulge, so that the curved top may give an uncomfortable feeling to the wearer's body.

In addition, since two elastic leg openings are formed by sewing the front and rear parts, the sewn portion extends in the center of the crotch portion, thereby connecting the two leg openings. Therefore, when the sanitary napkin is attached to the panties, there is no basis for firmly holding the sanitary napkin, and therefore, leakage may occur due to twisting of the sanitary napkin into a narrow shape or peeling of the adhesive portion of the sanitary napkin from the body of the pant.

According to the shorts disclosed in JP-A-2002-660, the elastic lifting member provided at the rear extends in the longitudinal direction and generates a rebounding contraction force. This recoil force acts substantially linearly along the spinal cord and then along the groin and crotch at the central portion of the posterior. A large lifting force in the front-to-rear direction is thus generated at the crotch portion, thereby pressing the sanitary napkin on the crotch portion to the vaginal opening.

The structure of the shorts is that the elastic lifting member provided on the rear portion extends in the longitudinal direction and thus generates an elastic lifting force for fitting the sanitary napkin on the body. However, since the elastic lifting part is provided on the rear part, and the front part is formed of a fabric having sufficient elasticity, when a thick sanitary napkin for night use is attached to shorts, because the elastic lifting part will be stretched due to the thickness and high rigidity of the sanitary napkin, hygienic The napkin does not conform adequately to the buttocks or crotch, and therefore does not exert adequate force to push the napkin even when it is lifted by the elastic lifting members located on the rear to fit it against the body.

A gap is thus created between the napkin and the body, so menstrual blood may run down the backside and leak out of the napkin. In addition, menstrual blood may spread through the gaps, increasing the contact area between the skin and menstrual blood, which will bring a large burden to the skin and may cause skin allergies.

Swelling or hematogenous disturbances may occur due to tension that puts great stress on the body if, for example, the sanitary napkin is used to prevent the wearer from moving involuntarily during sleep or when the waistband compresses the body by twisting .

There is therefore a need for a pant that does not compress the entire body, but that compresses and fits only the necessary parts of the sanitary napkin to the body.

Contents of the invention

An object of the present invention is to provide a sanitary napkin, which can easily fit a thick sanitary napkin for night use to the crotch or groin, prevent it from shifting, and prevent it from getting into the crotch, which can bring a A comfortable feeling without the uncomfortable feeling of restricting the wearer.

In view of the problems in the prior art, the present invention provides shorts formed by providing a highly elastic member formed of a highly elastic material, and a light elastic member formed of a light elastic material, and having bridging Front and rear crotch section. A light elastic member is provided in a central region from the rear end of the crotch portion to the rear portion of the waist holding portion. The light elastic member has a higher longitudinal modulus of elasticity than the highly elastic member covering the buttocks and abdomen around the central region. The lifting portion of the sanitary napkin, sewn with the light elastic member at the rear, is disposed in the middle of the crotch portion and has a longitudinal modulus of elasticity higher than that of the crotch fabric constituting the crotch portion covering the surrounding crotch region. With the above structure, the present invention is accomplished and can solve the above problems.

More specifically, the present invention provides:

(1) A pair of shorts formed by providing a highly elastic member formed of a material having a high degree of elasticity, and a lightly elastic member formed of a material having a light degree of elasticity, comprising:

the front; the rear; a crotch portion bridging between the front and the rear; a waist opening portion disposed in the upper edge of the front and in the upper edge of the rear; and disposed on both sides of the front and rear A pair of leg openings under both side edges of the upper portion, wherein the belt-shaped region provided in the substantially central region from the crotch portion to the rear portion of the waist opening portion is formed by the light elastic member.

According to the present invention, when the shorts are pulled up for wear, the light elastic member disposed in the belt-like region from the crotch portion to the waist serves to pull up the crotch portion connected thereto without extending. Therefore, the sanitary napkin attached to the crotch portion is pulled up and fitted on the crotch or the crotch of the body, thereby making it difficult to create a gap between the sanitary napkin and the body, thereby preventing menstrual blood from leaking. Since the shorts are made of highly elastic parts with high elasticity, they are comfortable to wear and will not give the wearer's whole body the uncomfortable feeling of restraint like a waist belt. Since the crotch portion bridging the front and rear is located around the pubic bone and the rear portion of the anus when wearing shorts, it is hygienic when the wearer puts on the shorts with the sanitary napkin attached to the crotch portion. The napkin can be stably attached to the crotch portion, thereby preventing twisting of the sanitary napkin, thereby preventing leakage of menstrual blood.

Here, "front" means the front portion of the pants body covering the abdomen, and "rear" means the rear portion of the pants body covering the rear side of the waist. "Pants body" means the part covering the waist of the body. "The crotch portion is provided to bridge between the front and the rear" means the crotch portion formed by connecting the crotch fabric to the front and the rear by sewing or the like, not connecting the front and the rear directly.

(2) The present invention provides the underpants as described in (1), wherein the lightly elastic member has a longitudinal modulus of elasticity greater than that of the highly elastic member.

According to the present invention, when the wearer attaches the sanitary napkin to the sanitary napkin filling fabric and pulls up the shorts to wear, the light elastic member is pulled upward, and the portion stitched between the crotch portion and the light elastic member becomes support point. Then, the force for pulling up the light elastic member becomes the force for pulling up the crotch portion and the force for suspending the night napkin attached to the napkin wrapping fabric. In this case, since the longitudinal elastic coefficient of the light elastic member is larger than that of the high elastic constant provided around the light elastic member, the force for suspending the sanitary napkin is effectively used as the The crotch portion of the light elastic member and the sanitary napkin attached to the crotch portion are pulled upwardly. Therefore, unlike the prior art shorts that have elastic at the central region of the rear, that is, the prior art shorts only have the back even when the wearer pulls up the shorts by maintaining the waist opening portion. However, the shorts of the present invention can easily fit a thick sanitary napkin for night use to the crotch or groin.

Preferably, the longitudinal elastic modulus of the lightly elastic component is about 10N-60N, more preferably 20N-50N. When the elastic coefficient is less than 10N, the active force for suspending the sanitary napkin is not enough, so it cannot be effectively used as the active force for suspending the sanitary napkin. In this case, when the wearer pulls the pant upwards, the light elastic members overextend, so the force exerted by the wearer is not effective as a force to pull the sanitary napkin upwards. A modulus of elasticity greater than 60N is not preferred because it tends to generate an upward pull force greater than that required to fit the sanitary napkin, so that the sanitary napkin digs into the body more than the body needs, which can cause discomfort or pain. For example, a material that is not inherently elastic, such as a plastic strap or string, is not preferred because it allows the force of pulling up the pant to be directly used as the force of pulling up the sanitary napkin, thus causing the sanitary napkin to burrow too deeply into the interstices of the body.

The longitudinal direction of the lightly elastic member and the longitudinal direction of the highly elastic member correspond to the direction in which the shorts are pulled up or down when worn (the Y direction in Figures 1 and 2) and the direction from the crotch portion and leg openings towards the waist . The crotch means the portion of the body between the legs, including, for example, the vaginal opening, perineum, and anus. The modulus of elasticity means the value obtained by dividing the tensile load applied when the parts of the shorts (mild elastic part, highly elastic part, sanitary napkin lifting part, and fixing part) are pulled up and extended by the stretch ratio at that time, the elastic The larger the coefficient, the less likely it is to stretch.

(3) The present invention provides a pair of shorts, comprising a front part; a rear part; a crotch part provided for bridging between the front part and the rear part, and the crotch part is used for holding a sanitary napkin; and a pair of leg openings disposed under the side edges of the front and the side edges of the back, wherein the crotch portion from the front to the back A sanitary napkin lifting portion is provided in the central portion, and the longitudinal elastic coefficient of the sanitary napkin lifting portion is greater than that of the fabric constituting the crotch portion.

According to the present invention, since the longitudinal elastic modulus of the lifting portion of the sanitary napkin is greater than that of the surrounding crotch fabric, the lifting portion of the sanitary napkin is pulled up by a force greater than that of the surrounding fabric, which produces a The force that lifts the central portion of the sanitary napkin (towards the crotch of the body) attached to the crotch portion. The modulus of elasticity of the lifting portion of the sanitary napkin is preferably 5N-30N, more preferably 10-25N. When the elastic coefficient is less than 5N, the active force of the suspended central part of the sanitary napkin will not effectively act against the upward pulling force of the light elastic part. As described in (1), since the crotch portion is provided to bridge between the front portion and the rear portion, it is located around the pubic bone and the rear portion of the anus in the worn state. Therefore, when the wearer attaches the sanitary napkin to the crotch portion and puts on the shorts, the sanitary napkin can be stably attached to the crotch portion, thereby preventing the sanitary napkin from twisting, thereby avoiding the risk of menstrual blood leakage. When a waterproof fabric with waterproof performance is provided on the inner side of the crotch fabric constituting the crotch portion, the waterproof fabric can be combined with the crotch fabric and the front or along with the crotch fabric and the rear. Or with the seamed part that is sewn together in the back. Therefore, the number of stitched parts is not increased, and thus an uncomfortable feeling or spoiled appearance in a worn state can be prevented. The longitudinal direction of the lifting portion of the sanitary napkin is the direction between the front and the rear.

(4) The present invention provides a pair of shorts, comprising a front part; a rear part; a crotch part provided for bridging between the front part and the rear part, and the crotch part is used for holding a sanitary napkin; The waist opening portion in the upper edge of the edge and the back; a pair of leg openings set under the side edges of the front and the side edges of the back, and a pair of leg openings set in a high elastic material A light elastic part made of a material having a slight elasticity among highly elastic parts, wherein the light elastic part is provided in the substantially central region from the crotch to the rear of the waist opening part, and the sanitary napkin lifting part is provided in In the middle of the crotch portion from the front to the rear, the light elastic member and the sanitary napkin lifting portion are sewn together at the ends of the crotch portion on the sides of the rear portion, the light elastic member has a longitudinal modulus of elasticity greater than The longitudinal modulus of elasticity of the highly elastic member, the lifting portion of the sanitary napkin is greater than that of the fabric constituting the crotch portion.

According to the present invention, as described in (2) and (3) above, when the shorts are worn, the force of pulling up the slight elastic member is used as the force of pulling up the lifting portion of the sanitary napkin. The lifting portion of the sanitary napkin is pulled up with a force greater than that of the fabric making up the surrounding crotch portion, which acts as a force that pulls the central portion of the sanitary napkin attached to the crotch portion upward (towards the crotch of the body). crotch part) lifting force. Thus, the sanitary napkin is fixed so that it fits better in the crotch. As described in (1), since the crotch portion is provided to bridge between the front portion and the rear portion, it is located around the pubic bone and the rear portion of the anus in the worn state. Therefore, when the wearer puts on the shorts with the sanitary napkin attached to the crotch portion, the sanitary napkin can be stably attached to the crotch portion, thereby preventing the sanitary napkin from being twisted, thereby avoiding the leakage of menstrual blood.

(5) The present invention provides the shorts as described in any one of (1) to (4), wherein the crotch portion is formed by sewing crotch fabric to the front portion and to the rear portion.

According to the present invention, the seamed parts are respectively present between the lower end of the front part and the front end of the crotch fabric and between the lower end of the rear part and the rear end of the crotch fabric, and do not exist in the width direction of the crotch part (facing toward a in the middle part towards the direction of the leg opening). In other words, each stitching portion is located around the pubic bone and the rear portion of the anus in the worn state. Therefore, when the wearer puts on the shorts with the sanitary napkin attached to the crotch portion, the sanitary napkin can be stably attached to the crotch portion, thereby preventing the sanitary napkin from being twisted, thereby avoiding the leakage of menstrual blood.

(6) The present invention provides the shorts as described in any one of (1) to (5), wherein the shorts further include a waist holding portion provided around a waist opening portion extending from the rear toward the front.

According to the present invention, the waist holding portion distributes the force of pulling up the light elastic member and the force of fixing the fastening member of the shorts laterally (along the width direction) and holds the force at the waist, and the shorts are in a wide The area fits around the waist.

(7) The present invention provides a pair of shorts as described in any one of (1) to (6), wherein the shorts include seams on the crotch portion, the waist retaining portion, and the highly elastic member sewn on the outside of the highly elastic member. Fixed parts in the basic central area of the front.

According to the present invention, when the lifting portion of the sanitary napkin is pulled toward the rear by the force of the light elastic member pulled up when the shorts are worn, the fixing member can control the extension of the highly elastic member. Therefore, since the part of the sanitary napkin lifting part provided on the side of the front part is fixed without being pulled due to the influence of the sanitary napkin lifting part and the light elastic part, the force for pulling the light elastic part is directly As a force to pull up the lifting portion of the napkin, thus pulling the napkin up towards the body and better fitting it in the crotch and groin.

(8) The present invention provides the shorts as described in any one of (1), (2) or (4)-(7), wherein the lightly elastic member is formed of a material having no elasticity in the longitudinal direction.

According to the present invention, since the lightly elastic member is substantially inelastic in the longitudinal direction, when the wearer attaches the overnight sanitary napkin to the sanitary napkin loading fabric and pulls the panties up to wear, the pull-up force effectively acts as a suspending sanitary napkin. The force of the towel. The slightly elastic member that can be used here is, for example, a fabric formed of woven fibers of nylon fibers or polyester fibers including members that are not elastic in the longitudinal direction, such as polyurethane fibers, having slight elasticity due to changes in the weaving structure, but not due to changes in the weaving structure. Elasticity due to the properties of the component.

(9) The present invention provides the underpants as described in any one of (3) to (8), wherein the lifting portion of the sanitary napkin is formed of a material having no elasticity in the longitudinal direction. According to the present invention, since the lifting portion of the sanitary napkin is substantially inelastic in the longitudinal direction, when the wearer pulls up the shorts to wear them, the force transmitted from the light elastic member is greater than the force acting around the fabric. The upward pulling force pulls the lifting portion of the sanitary napkin, and this upward pulling force acts as a force to lift the central portion of the sanitary napkin. The lifting part of the sanitary napkin used here is, for example, nylon fiber or polyester fiber for slightly elastic parts, including a fabric formed of braided fibers such as polyurethane fibers with no elastic parts in the longitudinal direction, with a slight difference due to changes in the weaving structure. Elasticity, but there is no elasticity due to the characteristics of the parts.

(10) The present invention provides the underpants as described in any one of (3) to (9), wherein the longitudinal modulus of elasticity of the lifting portion of the sanitary napkin is smaller than that of the lightly elastic member.

When wearing shorts, the light elastic member at the rear is used to fit the napkin on the body while extending the napkin lift in the crotch portion. In the case where the longitudinal elastic coefficient of the lifting part of the sanitary napkin is greater than that of the light elastic part, when the shorts are pulled up, the lifting part of the sanitary napkin does not extend, but the light elastic part at the rear part does, so it is difficult to apply The force that causes the sanitary napkin to be pulled up against the body.

(11) The present invention provides the underpants according to any one of (3) to (10), wherein the width of the lifting portion of the sanitary napkin is tapered from the front to the rear.

According to the present invention, the lifting portion of the sanitary napkin is pulled towards the back by the force of the light elastic member pulling up, and creates the force that suspends the sanitary napkin upwardly (toward the crotch of the body), thereby bridging the body's gap. In this case, since the width of the lifting part of the sanitary napkin starts from the part where the lifting part of the sanitary napkin is connected to the front part (the part in contact with the part around the pubic bone) as the widest part, it goes toward the vaginal opening, the perineum and the anus. The portion tapers so that an upward force is applied along the centerline of the sanitary napkin attached to the crotch portion relative to the surrounding portion. Then when the width of the part where the fixing part is connected to the front is substantially the same width as the width of the crotch, the part of the shorts that is in contact with the part around the pubic bone is stabilized, and this part of the shorts can be centered on the part around the vaginal opening superior. The narrowing of the width on the side of the fixing part is not preferable as a part around the perineum or anus, because the center of the sanitary napkin may move in the worn state and thus move away from the center of the vaginal opening.

The width of the lifting portion of the sanitary napkin may be tapered from the portion where the fixing member as the widest portion is connected to the front portion (the portion in contact with the body portion around the pubic bone) gradually becomes thinner toward the vaginal opening and the portion around the perineum, and then It gradually becomes wider from the part around the vaginal opening toward the part around the anus (but narrower than the width of the part sewn with the fixing member).

(12) The present invention provides the underpants as described in (11), wherein the width of the lifting portion of the sanitary napkin is 20 mm to 60 mm.

According to the present invention, since the width of the lifting portion of the sanitary napkin is not a narrow line, the force is not concentrated on a single point. Therefore, it is possible to reduce the sanitary napkin from getting into the body in the worn state when the sanitary napkin is attached to the sanitary napkin enclosing fabric, or bending and folding at the center to form an upwardly convex and curved top to the wearer's body. Possibility of comfortable feeling.

(13) The present invention provides the shorts as described in any one of (7) to (12), wherein the fixing member has a longitudinal modulus of elasticity larger than that of the highly elastic member in the longitudinal direction.

According to the present invention, the fastening member in the front center generates a force for fastening the part of the pant which is in contact with the part around the pubis. However, since the longitudinal elastic constant of the fixing member is larger than that of the highly elastic member, the extension of the front portion in the longitudinal direction is controlled. Since the fixing part controls the extension, the central area of the front part does not extend due to the influence of the light elastic part or the lifting part of the sanitary napkin, thereby fixing the part of the sanitary napkin in contact with the pubic bone. The longitudinal elastic coefficient of the fixing part is 10N-30N, more preferably 15N-25N. This is because the part of the front corresponding to the abdomen is a part that is greatly deformed due to the movement of the body, so when it is formed of fabric that cannot be stretched at all, the waist at the upper end of the front slides down, thereby losing the close-fitting nature. The fixing member is formed of a power net composed of nylon fibers and polyurethane fibers.

The longitudinal direction of the fixing member here means the direction in which the shorts are pulled up and down when worn, that is, the direction from the crotch portion to the leg opening toward the waist (Y direction in FIG. 2 ).

(14) The present invention provides the shorts as described in any one of (1), (2), or (4) to (13), wherein the upper end of the light elastic member on the side of the waist opening part is held with the waist. Parts are stitched in a basic V shape.

According to the present invention, the length of the fabric constituting the light elastic member from the waist holding portion to the crotch portion is such that the length from the center (central point of the V-shape) to the crotch portion of the V-shaped stitched waist holding portion is smaller than the left end thereof. and the right end. As the fabric is stretched, the stretch at the shorter part of the fabric is greater than at its longer part, so when the light elastic is pulled up, there is a greater force than that applied at the left and right ends to pull up from the center of the V to the crotch. Thus the central part does not slack, thus creating a force to pull the sanitary napkin up.

(15) The present invention provides the shorts as described in any one of (6) to (13), wherein the upper end of the fixing member on the side of the waist opening portion is sewn with the waist holding portion in a substantially V shape.

According to the present invention, the length of the fabric constituting the fixing member from the waist holding portion to the crotch portion is such that the length of the center (vertex of the V) of the fixing member is shorter than the left and right ends thereof. Since the elongation at the shorter part of the fabric is greater than at the longer part when it is stretched, when the fixing part is pulled up, it is fixed by a force greater than that applied to the left and right ends. The central part of the part is pulled up. Thus the central part does not slack, thus creating a force to pull the sanitary napkin up.

(16) The present invention provides a kind of shorts as described in any one of (1) to (15), wherein the crotch part includes the inner sanitary napkin-fitting fabric, and the front and rear ends of the sanitary napkin-fitting fabric are sewn with the crotch part Together, the side ends of the sanitary napkin filling fabric are not sewn together with the crotch portion.

According to the present invention, the sanitary napkin wrapping fabric is only sewn to the crotch portion at the front and rear ends without being completely integrated with the crotch portion, and it is independently separated from the crotch portion on the inner side of the crotch portion. Therefore, since the sanitary napkin enclosing fabric does not extend in the front-rear direction (in the direction toward the front and rear) together with the crotch portion, or even when it is extended, the amount of extension is very small, so the connection is reliably maintained. Sanitary napkins on it. Also, since it is sewn with the crotch part at the front and rear ends, it can be sewn together with the crotch fabric that makes up the crotch part. Therefore, the number of stitched parts does not increase, and thus it is possible to prevent an uncomfortable feeling in a worn state or impair the appearance. The front end and the rear end mean the ends of the sanitary napkin filling fabric on the front side and the rear side.

(17) The present invention provides the underpants as described in (16), wherein the length of the sanitary napkin-fitting fabric is equal to or greater than the length of the crotch fabric constituting the crotch portion.

According to the present invention, even when the crotch portion formed by the crotch fabric of the elastic fiber extends when the wearer pulls up the shorts to put them on, it does not extend because the length of the sanitary napkin filling fabric is long enough, or even when it When extended, the amount of extension is very small, so that the sanitary napkin can be reliably held. When the crotch portion is extended, the lifting portion of the sanitary napkin is pushed toward the crotch, thereby pushing the sanitary napkin toward the crotch.

(18) The present invention provides the shorts as described in any one of (1), (2) or (4) to (17), wherein at the boundary between the highly elastic part and the slightly elastic part, the high elastic Parts gradually decrease in elasticity toward slightly elastic parts.

According to the present invention, since the elastic part gradually decreases from the highly elastic part, when the wearer pulls up the shorts and wears them, the extension of the light elastic part gradually decreases, so that the shorts can fit the wearer's body without strain. Come feel uncomfortable.

(19) The present invention provides the shorts as described in any one of (1), (2) or (4) to (17), wherein at the boundary between the highly elastic part and the lightly elastic part, the elasticity from There is a discontinuous change from a highly elastic component to a slightly elastic component.

By arranging the elasticity of the lightly elastic member to vary discontinuously from the highly elastic member to the slightly elastic member, the highly elastic member and the lightly elastic member are clearly separated. The performance of the fit may be reduced, but the effect of lifting the sanitary napkin is enhanced, as compared to the case where they are not significantly separated (ie, the elasticity changes continuously).

(20) The present invention provides shorts as described in any one of (1) to (19), wherein in the case of a three-dimensional structure of the shorts, the central height length from the crotch portion to the waist opening portion and the shortest length The dimension ratio between the height and length of the side portion from the leg opening to the waist opening portion is set to be 100 for the former and 80-200 for the latter.

According to the present invention, due to the long height and length of the side part of the shorts, the leg straps placed at the leg openings do not tighten from the part around the crotch to the side bone, but tighten the femur area of the wearer . The oblique pull-up force due to the leg straps therefore does not act on the crotch portion and therefore does not penetrate into the crotch. In addition, since the large pull-up force generated by the leg straps does not act on the crotch portion, the sanitary napkin on the crotch portion is reliably suspended upward by the light elastic member provided on the rear portion, thereby This implementation is more cohesive.

(21) The present invention provides the underpants as described in any one of (1) to (20), wherein the lightly elastic member, the sanitary napkin lifting portion, and the waist holding portion have a different color tone or color from that of the highly elastic member.

According to the present invention, since the light elastic part, the lifting part of the sanitary napkin, and the waist holding part have a different color or texture from that of the high elastic part, they can be distinguished visually. In this way, since the waist holding part, the light elastic part and the lifting part of the sanitary napkin are conspicuous, the wearer can easily recognize these three parts and can easily realize the effect of the lifting part. Since these lifting parts arranged in the center of the shorts have a different appearance from other fabric parts, when the wearer connects and positions the sanitary napkin on the shorts, it is easy to align the center of the sanitary napkin with the center of the shorts, so the sanitary napkin The center can fit properly in the center of the crotch of the body. Therefore, the effect of blocking the gap to prevent leakage of liquid such as menstrual blood can be improved.

(22) The present invention provides the shorts described in any one of (1) to (21), including instructions on how to wear them displayed on the front or rear.

According to the present invention, the wearer can control the fit performance of the sanitary napkin by reading instructions. The wearer attaches the sanitary napkin to the napkin-carrying fabric on the shorts by adhesive or the like, pulls up the shorts by holding the upper side of the shorts while pulling them up, and wears the shorts to a designated position on the body. This manner of wearing provides some degree of bonding to the sanitary napkin. But since the degree of bonding required is different for everyone, those who would like a better fit can do so by following instructions such as "A better fit can be achieved by pulling the part on the extension of the light elastic at the center of the back" the bonding they require. In this way, those who desire a high degree of bonding are guided so that they can easily realize how to wear it.

(23) The present invention provides the shorts as described in (22), wherein instructions are provided on the light elastic member near the waist opening portion.

According to the present invention, a better fit of the sanitary napkin can be achieved by pulling up the commanded portion. In other words, while wearing the shorts by holding the upper side of the shorts, the light elastic member is pulled up by pulling the command portion more upward. By pulling up on the light elastic, the napkin can be pushed more firmly towards the crotch of the body, as described above, so a better bond can be obtained.

Fig. 12 is a view showing the relationship between elongation and tensile strength of a mildly elastic member.

As shown in FIGS. 1 to 4 , the shorts 10 have a front portion 11 , a rear portion 12 , and a crotch portion 13 between the front portion 11 and the rear portion 12 . A waist opening portion 14 is formed in upper edges of the front portion 11 and the rear portion 12 , and a pair of leg openings 15 are formed under the front portion 11 and the rear portion 12 . Inside the crotch portion 13 is provided a sanitary napkin wrapping fabric 16 to which a sanitary napkin is attached (see FIG. 8). A waist holding portion 17 extending from the front portion 11 to the rear portion 12 is provided around the waist opening portion 14 . A light elastic member 18 extending from the crotch portion 13 toward the waist holding portion 17 is provided at a central region of the rear portion 12 . A highly elastic member 19 is provided in all other regions of the front portion 11 and the rear portion 12 except the waist holding portion 17 and the fixing member 20 , and is sewn at substantially the center of the front portion 11 . A partial height elastic member 19 provided in the rear portion 12 forms a rear side height elastic member 19 b extending from the light elastic member 18 toward the front portion 11 . The other portion of the highly elastic member 19 provided in the front portion 11 forms a front side highly elastic member 19a. In the central area of the front part 11 , a fastening part 20 is provided, which is sewn with a highly elastic part 19 . The highly elastic member 19 is also sewn in the front portion 11 and the rear portion 12 with the crotch portion 13 and the waist retaining portion 17 . In the middle of the crotch portion 13 bridging the light elastic member 18 and the fixing member 20, a sanitary napkin lifting portion 21 is provided. The waist belt 22 is provided along the upper side of the waist holding portion 17 formed in the upper edges of the front part 11 and the rear part 12 , and the leg belt 23 is provided around the leg opening 15 . When the central height length is 100, the dimension between the central height length La from the crotch portion 13 to the waist opening portion 14 and the side height length Lb from the leg opening 15 to the waist opening portion 14 as the shortest length The ratio is between 80 and 200.

The highly elastic member 19 may be formed of braided fibers, such as a combination of nylon fibers and polyurethane fibers, or a combination of polyester fibers and polyurethane fibers, or a combination of nylon fibers, polyester fibers, and polyurethane fibers. Braided fibers other than the above combinations may also be used as long as the modulus of elasticity thereof does not exceed 10N. The crotch portion 13 is formed by providing a crotch fabric 24 sewn with highly elastic members 19 on the sides of the front portion 11 and on the sides of the rear portion 12 . The crotch fabric 24 is similar to the highly elastic member 19 and is formed of elastically stretchable woven fibers, such as a combination of nylon fibers and polyurethane fibers, or a combination of polyester fibers and polyurethane fibers, or nylon fibers, polyester fibers and polyurethane fibers. Fiber bonding. The waist belt 22 provided along the waist opening portion 14 and the leg belt 23 provided along the leg opening 15 are formed of an elastic material such as elastic woven fabric of polyurethane fiber, a synthetic rubber sheet, or a natural rubber sheet. The longitudinal direction here means the direction (Y direction in FIG. 1 ) when the waist opening portion 14 and the crotch portion 13 are defined as upper and lower sides, that is, the direction of pulling up and pulling down the shorts 10 when wearing the shorts. The direction, the transverse direction means the direction (X direction in FIG. 1 ) perpendicular to the longitudinal direction, that is, the width direction of the shorts 10 .

A waist holding portion 17 is formed around the waist opening portion 14 of the shorts 10 to form a V-shaped edge with a pointed edge pointing toward the center of the front portion 11 and the rear portion 12, and the waist holding portion is connected to the front portion 11 and the rear portion 12. The highly elastic part 19 is stitched. The waist holding portion 17 is a woven fabric whose modulus of elasticity in the longitudinal direction is higher than that in the transverse direction. The woven fibers are, for example, a combination of nylon fibers and polyurethane fibers, a combination of polyester fibers and polyurethane fibers, or a combination of nylon fibers, polyester fibers, and polyurethane fibers. The waist belt 22 provided around the waist opening portion 14 is, for example, a polyurethane belt, a natural rubber belt, or a synthetic rubber belt of about 10 mm, sewn to the waist holding portion 17 in a stretched state.

The waist holding portion 17 is used to disperse the force of pulling up the lifting portion 21 of the sanitary napkin through the light elastic member 18 or the fixing member 20, and maintain the force at the waist, so it is desirable to limit the longitudinal extension of the waist holding portion 17 so that when The waist holding portion 17 is held and fixed at the waist when the shorts 10 are worn. It is desirable to have a transverse modulus of elasticity greater than that of the highly elastic member 19 because the force to restrain the waist opening portion 14 is increased and thus prevent the shorts 10 from sliding down.

A light elastic member 18 is provided in a substantially central region of the rear portion 12 . The upper end of the slight elastic member 18 is sewn with the central portion (the part near the sharp edge of the V-shaped edge) of the waist holding portion 17, and the lower end of the slight elastic member 18 is connected with the rear portion 12 side of the crotch portion 13. The upper end (the rear end of the crotch portion 13) is sewn, and the both side ends of the light elastic member 18 are sewn with the highly elastic member 19. The light elastic member 18 extends from the waist holding portion 17 to the rear end of the crotch portion 13 and tapers toward the rear end of the crotch portion 13 . The narrow portion has a width of 10mm to 30mm, preferably about 20mm. The width of the wide portion where the light elastic member 18 is sewn with the waist holding portion 17 is 30 mm to 130 mm, preferably about 60 mm. The light elastic member 18 may extend to the waist opening portion 14 .

The length of the middle region of the mild elastic member 18 (corresponding to Lc in FIG. 1 ) is shorter than the length of the side ends of the mild elastic member 18 (corresponding to Ld in FIG. 1 ), and the upper end of the mild elastic member 18 and the waist holding portion The rear ends of 17 are sewn together to form a V-shaped portion having a V-shaped edge as described above. Therefore, when wearing the shorts 10, compared with the fabric located in the side ends of the light elastic member 18, the fabric located in the middle region of the light elastic member 18 extends from the sharp edge of the V-shaped portion to the crotch portion 13. The fabric stretches more. That is, the stretching force that lifts the fabric in the middle region of the light elastic member 18 is greater than the force that lifts the fabric in the side ends of the light elastic member 18 . When the mild elastic member 18 is pulled up, since the length of the middle region of the mild elastic member 18 is shorter than the length of the side ends of the mild elastic member 18, by using a ratio of pulling up the fabric located in its left and right ends, The still greater force pulls up the fabric located in the middle region. Thus the central portion does not slack, thus creating a force that pulls the sanitary napkin 25 up. Regarding the relationship between these lengths, the dimensions and elastic ratios were measured before and after wearing the shorts 10 on the puppet. Dimensions and elastic ratios are shown in Table 1. As shown in Table 1, the length at the middle region of the lightly elastic member 18 is shorter before the shorts 10 are worn, and the elastic ratio is larger when worn.

1) Center portion (Lc): the length extending from the sharp edge of the V-shaped portion to the crotch portion.

2) Side portion (Ld): the length of the side line extending from the side portion of the V-shaped portion to the crotch portion.

The lightly elastic member 18 may be formed from a woven fabric, such as a combination of nylon fibers and/or polyester fibers, a combination of nylon fibers and polyurethane fibers, a combination of polyester fibers and polyurethane fibers, or a combination of nylon fibers, polyester fibers, and polyurethane fibers. combination. The fabric forming the lightly elastic member 18 is a material such as polyurethane fiber that has no elasticity in the longitudinal direction, so that it has slight elasticity brought by the weaving structure, but there is no elasticity produced by the material itself, that is, the longitudinal elastic coefficient of the fabric is greater than The longitudinal elastic coefficient of the highly elastic member 19. Therefore, the slightly elastic member 18 is less likely to stretch than the highly elastic member 19 . In this structure, since the highly elastic member 19 covering around the buttocks and abdomen of the body is formed of longitudinally and transversely elastic material, it follows the deformation of the body caused by the movement of the wearer. But the slightly elastic part 18 disposed substantially in the central region of the rear part 12 is hardly affected by the movement of the highly elastic part 19 because its longitudinal elastic coefficient is greater than that of the highly elastic part 19 .

The elasticity of the slightly elastic member 18 is such that the coefficient of elasticity is preferably 10N-60N, more preferably 20N-50N. When the coefficient of elasticity is less than 10N, the active force for lifting the sanitary napkin 25 will not be enough; when the coefficient of elasticity is greater than 60N, the sanitary napkin 25 will enter the gap of the body too much (Fig. 11). Even in the case where the light elastic member 18 does not extend at all, although the force for pulling up the panties 10 is directly used as the force for pulling up the sanitary napkin 25, the force for pulling up the sanitary napkin 25 is greater than that for installing the sanitary napkin. 25, which can cause excessive entry of the sanitary napkin 25 into the body, causing an uncomfortable sensation or pain, which is undesirable. Conversely, when the elasticity is too great, the light elastic member 18 overextends when the wearer pulls the panties 10 up, and thus does not effectively act as a force for pulling the sanitary napkin 25 up.

On the other hand, the elastic constant of the highly elastic member 19 is less than 10N, more preferably in the range of 2N-3N when extended by 10-30%. More specifically, when the shorts are extended about 20% in the worn state, the applied tensile load is 0.4-0.6N, thereby achieving a comfortable and gentle fit along the body. The coefficient of elasticity in the worn state means the coefficient of elasticity obtained when the shorts are worn on a medium-sized puppet.

The lightly elastic member 18 may have an elongation that is the same over the entire area, as shown in FIG. 5, or may have an elongation that changes gradually or discontinuously, decreasing from the left and rear ends toward the middle area. FIG. 5 shows the lightly elastic member 18 in an enlarged manner, wherein the lightly elastic member 18 is shown in a schematic manner with its elongation gradually changing from the left and right ends 18a towards the middle region 18b.

As a reference only, Figure 12 shows the relationship between elongation and tensile strength of the light elastic member 18 of the shorts 10 of the present invention as compared to prior art shorts. In FIG. 12, the vertical axis represents tensile load in Newton (N), and the horizontal axis represents elongation in %. Curve A corresponds to the shorts of the present invention and curve B corresponds to the prior art shorts.

As shown in FIG. 12, when the prior art light elastic member provided in the substantially central region of the rear portion of the shorts is extended by 30%, the applied tensile load is P1. On the other hand, when the light elastic member 18 of the shorts 10 of the present invention is extended by 30%, the applied tensile load is P2, which means that the tensile strength of the shorts 10 of the present invention is greater than that of the prior art shorts . In other words, the shorts 10 of the present invention have a greater tensile load than prior art shorts at the same elongation. Even when the shorts 10 of the present invention are stretched by only 10% in the worn state, the tensile strength applied to the shorts 10 of the present invention is P3 greater than that of the prior art shorts. In other words, even when the elongation is lower than prior art shorts, the tensile strength imparted to the shorts 10 of the present invention is relatively high, which means that the light elastic members 18 of the shorts 10 of the present invention are effectively a pull The active force of crotch part 13. Therefore, the active force for pulling up the night sanitary napkin 25 is increased, so that the sanitary napkin 25 is better adapted to the crotch part of the body.

The fastening part 20 of the shorts 10 is formed of a powerful net (power net), and is provided at a substantially central region of the front part 11. Its upper end is sewn with the waist holding portion 17 around the sharp edge of the V-shaped portion of the waist holding portion 17, and its side edges are sewn on the highly elastic member 19. The end of the crotch portion 13 on the front portion 11 side (front end of the crotch portion 13), its lower end is sewn together with the sanitary napkin lifting portion 21 and the sanitary napkin mounting cloth 16 constituting the crotch portion 13, or The highly elastic parts 19 are sewn together. The fixing member 20 tapers from the waist holding portion 17 toward the crotch portion 13 and is sewn together with a sanitary napkin lifting portion 21 disposed substantially in the middle of the crotch portion 13 . The width of the portion where the fixing portion 20 is sewn with the napkin lifting portion 21 is substantially the same as the width of the front end of the napkin lifting portion 21 disposed in one side of the front portion 11 . The upper end sewn with the waist holding portion 17 is formed into a substantially V shape with a width of 60mm-150mm, preferably 80-120mm.

The length of the central portion of the fixing member 20 (corresponding to Lc in FIG. 1 ) is shorter than the lengths of its left and right end portions (corresponding to Ld in FIG. The back end is stitched to form the V-shaped section as above. Therefore, as in the case of the mild elastic member 18, when the fixing member 20 is pulled up, the central part of the fixing member 20 is supported by a greater force than the force used to lift the left and right end portions thereof. pull (see Table 1). Therefore, the central portion does not loosen, and a force for pulling up the sanitary napkin 25 is generated.

The powerful net constituting the fixing part 20 is formed by nylon fabric and polyurethane fibers higher than 100dtex, and the longitudinal elastic coefficient is greater than that of the highly elastic part 19, that is, the strong net fabric constituting the fixing part 20 is larger than the highly elastic part. 19 has poor elasticity. The longitudinal tensile strength of the fixing member 20 makes its modulus of elasticity be 10N-30N, more preferably 15N-30N. The type or mixing ratio of the fibers in the strong net constituting the fixing member 20 is not limited thereto, and may be appropriately selected to obtain the above-mentioned effects.

As shown in FIG. 6, the sanitary napkin lifting portion 21 is disposed substantially in the middle of and forms part of the crotch portion 13 through a crotch fabric 24 of a material similar to the highly elastic member 19. Forming. One end of the lifting part 21 of the sanitary napkin is sewn with the lower end of the light elastic part 18 provided at the substantially central area of the rear part 12, and the other end of the lifting part 21 of the sanitary napkin is sewn with the fixing part provided at the substantially central area of the front part 11. 20 seams at the lower end. Both side ends of the fixing member 20 are sewn with the crotch fabric 24 forming the crotch portion 13 . The sanitary napkin lifting portion 21 extends from around the portion in contact with the pubic bone toward the portion around the anus, and tapers from the front end on the front portion 11 side toward the rear end on the rear portion 12 side. The width of the lifting portion 21 of the sanitary napkin is 50mm-80mm, more preferably about 70mm at the wider part, and 10-30mm, more preferably about 20mm at the narrower part.

The lifting portion 21 of the sanitary napkin is similar to the light elastic member 18 and is formed of a woven fabric, such as a combination of nylon fibers and/or polyester fibers, a combination of nylon fibers and polyurethane fibers, a combination of polyester fibers and polyurethane fibers, or a combination of nylon fibers , The combination of polyester fibers and polyurethane fibers, including non-elastic materials such as polyurethane fibers in the longitudinal direction, has slight elasticity brought about by changes in the weaving structure, but there is no elasticity produced by the material itself. It is formed of a fabric having a longitudinal modulus of elasticity smaller than that of the lightly elastic member 18, that is, the fabric constituting the lifting portion 21 of the sanitary napkin is more elastic than the lightly elastic member 18.

The elasticity of the lifting portion 21 of the sanitary napkin is preferably such that its modulus of elasticity is 5N-30N, more preferably 10N-25N. When the modulus of elasticity is less than 5N, the force for lifting the central portion of the sanitary napkin 25 is insufficient. When the modulus of elasticity is greater than 30N, the elasticity exceeds that of the mildly elastic member 18, so that it is difficult to perform a suspending action to make the central portion of the sanitary napkin 25 fit the gap of the body.

The lifting portion 21 of the sanitary napkin can be formed in such a manner that its width is gradually tapered from the portion (the widest portion) sewn with the fixing member 20 toward the middle region, as shown in FIG. The portion where the elastic member 18 is sewn is increased again. In this case, the width of the lifting portion 21 of the sanitary napkin at the portion sewn with the light elastic member 18 is smaller than the width at the portion sewn with the securing member 20 .

As shown in FIG. 8, the sanitary napkin enclosing fabric 16 is disposed on the inner side of the crotch portion 13. As shown in FIG. The front end of the sanitary napkin packing fabric 16 is sewn on the crotch portion 13 on the front portion 11 side, and the rear end of the sanitary napkin packing fabric 16 is sewn on the crotch portion 13 on the rear portion 12 side. The sanitary napkin wrapping fabric 16 is a fabric-membrane formed by weaving waterproof fabric formed by laminating polyester circular dappled (polyurethane) and polyester woven fabric for protecting the surface of the laminated film, and sewing together around the left and right ends. overall. The length L2 of the sanitary napkin wrapping fabric 16 is the same as or greater than the length L1 of the crotch portion 13 as shown in FIG. 9 . More specifically, the crotch portion 13 has a length of 140-190 mm, preferably about 160 mm. The length L2 of the sanitary napkin wrapping fabric 16 is in the range of 140-220 mm, preferably about 200 mm.

The highly elastic member 19 of the shorts 10 is formed from a black near-matte fabric. The waist holding portion 17, the light elastic member 18, and the napkin lifting portion 21 are formed of brown fabric. The strong net constituting the fixing part 20 may be of a different color than the fabric of the highly elastic part 19 . In this way, it is preferable to make the waist holding portion 17, the light elastic member 18, the sanitary napkin lifting portion 21, and the fixing member 20 different in color from the highly elastic member 19 or regardless of whether the color is the same, by changing the amount of titanium oxide mixed to make them The reflectivity of the sanitary napkin is different, so that these parts used to lift the sanitary napkin can be distinguished by the naked eye.

Referring to Figures 10 and 11, the behavior of the light elastic member 18, the sanitary napkin lifting portion 21, and the securing member 20 when wearing the panties 10 of the present invention will be described. Figure 10 is a schematic cross-sectional view of a pant around the crotch of the body showing how the light elastic member, the lifting portion of the sanitary napkin and the securing member move around the crotch of the body when wearing the pant of the present invention. Reference sign BD indicates the body and reference sign LG indicates the legs. Figure 11 is a schematic transverse cross-sectional view of the portion of the pant around the vaginal opening, showing the behavior of the portion of the pant near the vaginal opening in the worn state. Reference mark I in FIG. 11 is the vaginal opening, and reference mark IT between the legs LG represents the inner side of the femur.

When the shorts 10 are worn, as shown in FIG. 10, by receiving the lifting force T1 brought by the light elastic member 18, it is used to fix the joint at the point A (the part where the fixing member and the crotch portion 13 are sewn together) as a supporting point. , which is in contact with the pubic bone of the body), the force T3 that pulls the lifting portion 21 of the sanitary napkin toward the rear to cover the body gap appears. Then the force T3 for pulling up the lifting portion 21 of the sanitary napkin becomes the force for pulling up the central portion of the sanitary napkin 25 . The width of the lifting portion 21 of the sanitary napkin is about 70 mm around point A and gradually increases towards the vaginal opening, perineum and anus (towards point B, which is the seamed portion between the light elastic member 18 and the crotch portion 13). Tapers to a width of approximately 20mm. In this way, since the width of the napkin lifting portion 21 is wide at the point A, the point A is fixed so that the movement of the sanitary napkin lifting portion 21 to the right or to the left can be prevented, and the center of the sanitary napkin lifting portion 21 can be around the vaginal opening. If the width of the lifting portion of the napkin at point A is as narrow as 20mm, the lifting portion 21 of the sanitary napkin may move to the right or left, so its center may not be located around the vaginal opening in the worn state, which is not preferable .

As shown in Figure 11, since the width of the lifting portion 21 of the sanitary napkin is as narrow as 20mm near the vaginal opening, the elastic coefficient of the lifting portion 21 of the sanitary napkin is higher than that of the surrounding fabric, so it extends under the stronger force and A force T4 for lifting the central portion of the sanitary napkin 25 upward is generated.

As shown in FIG. 10, the sanitary napkin lifting portion 21 is pulled rearward (rear portion 12) by the force T1 of the light elastic member 18 pulled toward the upper side of the rear portion 12. As shown in FIG. Therefore, a force is generated at point A to move the lifting portion 21 of the sanitary napkin backward. When the sanitary napkin lifting portion 21 is moved backward following the point A, the force exerted by the sanitary napkin lifting portion 21 to fit the sanitary napkin 25 to the body is hardly affected. In other words, when the entire sanitary napkin lifting portion 21 is moved backward, no force is generated to fit the sanitary napkin 25 to the body. In order to avoid this state, it is preferable to fix the point A as firmly as possible. On the other hand, the fixing member 20 of the front part 11 applies a force to fix the point A. As shown in FIG. In other words, by sewing the strong net constituting the fixing part 20 to the outside of the highly elastic part 19 of the shorts 10, it is possible to weaken the force T2 generated in the front part 11 which tends to extend in the vertical direction. In this way, the extension of the front portion 11 is reduced by sewing the securing member 20 thereon, thus securing the point A without being pulled by the light elastic member 18 and the lifting portion 21 of the sanitary napkin. The longitudinal modulus of elasticity of the fabric constituting the strong net of the fixing member 20 is preferably 10N-30N, because if it is formed by a non-elastic fabric, the waist opening part at the upper end of the front part 11 may slide down because it is different from the front part 11. The contact abdomen is a portion that deforms significantly according to the movement of the wearer's body, and thus there is a risk of impairing the fit.

Here point A corresponds to the stitching point between the fixing part 20 and the crotch part 13, that is, around the part in contact with the pubic bone of the body, and point B corresponds to the seam between the light elastic part 18 and the crotch part 13 The sutured part between, that is, the part on the side of the rear part 12 with respect to the anus, and the part about 150mm-200mm backward from the pubic bone (on the side of the rear part 12).

The method for measuring the elasticity of pant components (light elastic components, sanitary napkin lifting portion, fastening components, and highly elastic components) is described below.

<Measurement of slightly elastic parts>

The seam position where the rear end of the crotch portion 13 is sewn together with the light elastic member 18 on the rear portion 12 side (the rear end of the crotch portion 13), and the distance from the seam portion toward the waist opening portion 14 is 100 mm The position at the clamping distance is clamped with a clamp (the size of the clamping surface is a rectangle of 30 mm × 25 mm), and the light elastic member 18 is extended by 50% at a tensile speed of 100 mm/min using a tensile testing machine. 10% is measured as a tensile load.

<Measurement of the lifting part of the sanitary napkin>

The seamed portion where the sanitary napkin lifting portion 21 is stitched to the front portion 11, and the position at a clamping distance of 150 mm from the seamed position towards the rear portion 12 of the underpants 10 is clamped with a clamp (the size of the clamping surface is 35mm×25mm rectangle), using a tensile testing machine to extend the lifting part of the sanitary napkin by 50% at a tensile speed of 100mm/min, and measure the tensile load every 10% of the stretch.

<Measurement of fixed parts>

The seamed portion that sews the fixing member 20 with the crotch portion 13 on the front portion 11 side (the front end of the crotch portion 13), and the seamed portion at a clamping distance of 80 mm toward the waist opening portion 14 of the shorts 10 from the seamed position The position is clamped with a jig (the size of the clamping surface is a rectangle of 35mm×25mm), and the fixed part 20 is extended by 50% at a tensile speed of 100mm/min using a tensile tester, and the tensile load is measured every 10% of the stretch .

<Measurement of highly elastic parts>

The highly elastic member 19 of the shorts 10 was cut to a size of 130mm long x 25mm wide. The cut strips are then clamped by clamps (clamping surface dimensions are a rectangle of 35mm x 25mm), and the highly elastic member 19 is stretched by 50% at a stretching speed of 100mm/min using a tensile testing machine, with each stretch of 10% Measure the tensile load once.

The modulus of elasticity is a value obtained by dividing the tensile load obtained in the above method by the corresponding extension ratio. For example, in the case of an extension of 20% and a tensile load of 10N, the modulus of elasticity is 10N/0.2=50N.

Referring to Fig. 13 and Fig. 14, the shorts 10a of the second embodiment and the shorts 10b of the third embodiment of the present invention will be described. Fig. 13 is a rear view showing the shorts 10a of the second embodiment, showing a state where the inner side faces outward and is folded in two so that the front and the rear are in contact with each other. Figure 14 is a rear view of another version of the second embodiment shown in Figure 13 . In this embodiment, the same components as those of the first embodiment are denoted by the same reference numerals, and repeated description thereof will be omitted.

The shorts 10a of the second embodiment shown in FIG. 13 are different from the shorts 10 of the first embodiment in that a waterproof fabric 26 with a width of 30-140 mm, more preferably of the order of 80 mm, is in the substantially central area of the rear portion 12 Set on the inner side of the shorts 10a, it extends from the crotch portion 13 to the waist holding portion 17. The waterproof fabric 26 is sewn on the crotch portion 13, the waist holding portion 17, and the light elastic member 18 so as to be integrated with the main body of the shorts 10a. The left and right ends of the waterproof fabric 26 are not sewn to the rear portion 12 of the shorts 10a so as not to inhibit the stretchability of the shorts 10a.

As in the case of the above-mentioned sanitary napkin mounting cloth 16, the waterproof fabric 26 is a waterproof fabric formed by weaving polyurethane-laminated polyester circular dappled and a polyester woven fabric for protecting the surface of the laminated film, at the left end. Sew together around the right end to form a fabric-membrane ensemble. The longitudinal and transverse elasticity of the waterproof fabric 26 does not impair the elasticity of the main body of the shorts 10a.

By providing the waterproof fabric 26 in the substantially central region of the rear portion 12 on the inner side of the shorts 10a, when the amount of menstrual blood discharged exceeds the absorbent capacity of the sanitary napkin, the menstrual blood flowing onto the sanitary napkin is absorbed by the waterproof fabric 26, Prevent leakage to the outside of the shorts 10a.

The waterproof fabric 26 may be provided in such a manner that the lower end of the waterproof fabric 26 does not extend all the way to the crotch portion 13 , but extends from the waist holding portion 17 to substantially the middle of the rear portion 12 . In other words, the waterproof fabric 26 may extend from the waist holding portion 17 to a portion not covered by the sanitary napkin so that the front end of the sanitary napkin is disposed on the waterproof fabric 26 in the worn state. The waterproof fabric 26 is sewn on the waist holding portion 17 and the light elastic member 18, and its lower end is on the rear side of the highly elastic member 19b of the rear portion 12 so as to be integrated with the main body of the shorts 10b. The left and right ends of the waterproof fabric 16 are not sewn together with the main body of the shorts 10b so as not to impair the elastic properties of the main body of the shorts 10b.

Referring to Fig. 15, a fourth embodiment of the present invention will be described. Fig. 15 is a view of shorts according to a fourth embodiment of the present invention, showing a state in which they are folded in two so that the front and rear parts are in contact with each other in a non-wearing state. FIG. 15A is a front view showing a state folded in two, and FIG. 15B is a rear view showing a state folded in two. In this embodiment, the same components as those in the first to third embodiments are denoted by the same reference numerals, and repeated description thereof will be omitted.

The structure of the shorts 10c of the fourth embodiment shown in Fig. 15A and Fig. 15B is similar to that of the shorts 10 of the first embodiment, but for the central height length La from the crotch portion 13 to the waist opening portion 14 and the length La at the leg opening. 15 to the shortest portion of the waist opening portion 14 between the side height length Lb dimension ratio, the length La is 100, then the length Lb is 50-80. The shorts 10c differ from the shorts 10 of the first embodiment in that they are not in the shape of boxer shorts and are therefore compact, with a central height length from the crotch portion to the waist opening portion that is shorter than the shortest distance between the leg openings and the waist opening portion. The side height length of the part is short. The shorts 10c may be provided with a waterproof fabric 26 as shown in FIGS. 13 and 14 on the inner side of the shorts 10c in a substantially central region of the rear portion 12 .

Referring to Fig. 16A, Fig. 16B and Fig. 17, a fifth embodiment of the present invention will be described. 16A and 16B are perspective views showing the panties of the fifth embodiment in three dimensions. Fig. 16A is a perspective view seen from the side of the front part 11, Fig. 16B is a perspective view seen from the side of the rear part 12, and Fig. 17 is an instruction provided on the shorts of the fifth embodiment. In this embodiment, the same components as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

The shorts 10c of the fifth embodiment shown in FIG. 15 have a structure similar to that of the shorts 10 of the first embodiment, but above the extension line of the light elastic member 18 provided in the substantially central region of the rear portion 12, at the waist. Instructions 27 are provided on the inner side of the shorts 10d at a position near the opening portion 14. As shown in FIG. Instruction 27 is a label showing the preferred way of using the shorts, sewn to the shorts 10d at the above locations as shown in FIG. 17 .

Therefore, when the wearer connects the sanitary napkin to the sanitary napkin loading fabric 16 (not shown) of the underpants 10d by adhesives or the like and pulls the underpants 10d to a designated position on the body for wearing, a higher adhesiveness of the sanitary napkin is desired. A knotty wearer can achieve her desired binding by pulling up the shorts 1Od while holding the sides, and then pulling the shorts further by holding the command 27 tabs.

Although the instruction 27 in this embodiment is formed by sewing a label indicating how to wear it, it is not limited thereto, and a clear display may be provided by printing or by embroidering yarn. Or it can be shown with a laundry tag. The position of the setting instruction 27 is not limited to the above-mentioned position, and can be appropriately determined according to the content of the instruction on how to wear it. It can also be provided on the outside of the shorts 10d. The contents of the instructions are not limited to the above-mentioned embodiments, either.

Although the shorts of the present invention have been described in detail with reference to the accompanying drawings, the present invention is not limited to these drawings and can be implemented by making modifications without departing from the above scope, and these modifications are also included in the technical scope of the present invention.

As mentioned above, the shorts of the present invention realize the easy fit of the thick sanitary napkin for night use relative to the crotch or the groin, and can prevent displacement. In addition, the present invention can reduce the entry relative to the crotch, so it is comfortable to wear Instead of forming an overall restraint like a belt. In other words, since the light elastic and the napkin lift lift the center of the night pad from the part corresponding to the vaginal opening and the rear to fit the body, the potential for leakage due to downflow is eliminated. gap so that the sanitary napkin can be reliably fitted to the body regardless of the wearer's posture. As a result, menstrual blood leakage due to flow along the groin can be eliminated, so the wearer can sleep in any position and wake up feeling completely relieved of fatigue. In addition, since the area where the menstrual blood spreads is small, the area where the skin comes into contact with the menstrual blood is narrowed, so the irritation to the skin is reduced, and skin inflammation, etc., can be prevented.

In addition, since the surrounding highly elastic parts other than the light elastic parts and the surrounding crotch fabric other than the lifting part of the sanitary napkin are formed of highly elastic and highly breathable fabrics, there will be no binding due to hardness, Excessive uncomfortable sensations of bloating and hematogenous disturbances. So there is no stress on the body, even after prolonged use there is no uncomfortable feeling of restriction.

In addition, since the abdomen (front) is controlled by the fastening member formed of a strong net, it prevents the shorts from sliding down and securely fixes the sanitary napkin.
