Description

  The present invention relates to an absorbent article provided with a bag. Specifically, in the absorbent article of the present invention, a bag body having an opening is attached to the skin non-facing surface side of the absorbent main body. For example, after the wearer excretes the absorbent article, When discarding or carrying an absorbent article individually, the bag body can be turned over so that the absorbent main body can be stored inside.

  Conventionally, an absorbent article for the purpose of absorbing and holding body fluid, such as a urine absorbing pad, an absorbent pad, a disposable diaper, or a sanitary napkin, is known. A general absorbent article is configured by disposing an absorbent body between a liquid-permeable top sheet and a liquid-impermeable back sheet. Since such an absorbent article absorbs and holds excreted body fluid, it is discarded after being used by being folded or rolled up. For example, a pants-type disposable diaper or the like generally has a disposal tape attached to the outer surface of the back body. When disposing of a pants-type disposable diaper, the user uses a disposal tape to keep the diaper rolled up and throw it away into a trash can.

  In addition, as a device for performing sanitary disposal of absorbent articles, it is also known to provide a space in the absorbent article itself for rolling up and storing used absorbent articles (for example, Patent Documents). 1). For example, the disposable diaper described in Patent Document 1 includes an auxiliary sheet on the skin-facing surface side of an area where no absorbent body exists among the back body corresponding to the back side of the wearer and the front body corresponding to the abdomen side. The disposable diaper of patent document 1 forms the storage space which has an opening part in the skin opposing surface side of a diaper using the auxiliary sheet | seat attached to the back body. When the disposable diaper is discarded, the diaper is rolled up to an area where the storage space exists and stored in the storage space, so that a sanitary disposal process can be performed.

  However, among the disposable diapers that are divided into a front body, a back body, and a crotch region located between them, as in the invention described in Patent Document 1, an auxiliary is provided in a region that forms the front body and the back body. Even if the seat was attached to create a space that could accommodate the diaper, such an auxiliary sheet was only useful when the diaper was discarded. In other words, an absorbent article such as a disposable diaper absorbs the excrement of the wearer during its use, and its main function is to prevent it from leaking out. When manufacturing a functional article, the technology for enhancing its leak-proof and cushioning properties should be costly. On the other hand, as for the elements for improving functions other than the functions that are exhibited during use, such as the functions that are exhibited at the time of disposal of the absorbent article, there is a request for cost reduction as much as possible. There is. In this regard, the disposable diaper described in Patent Document 1 forms a space in which a used diaper can be stored by an auxiliary sheet attached to the back of the body, thereby enabling more sanitary disposal. However, this auxiliary seat does not have functions such as improving the leak-proofing and cushioning properties of diapers, and does not have functions that are useful during the use of diapers. It was. For this reason, it has been said that it is difficult to actually manufacture and sell a disposable diaper having an auxiliary sheet as in Patent Document 1.

  Therefore, at present, the absorbent article has a configuration for forming a space in which the main body portion can be rolled up and stored so that disposal processing after use can be performed in a sanitary manner. However, it can be said that there is a demand for a technology that functions not only when the absorbent article is discarded, but also when the absorbent article is worn, so as to enhance its leakage prevention and cushioning properties.

Therefore, the inventor of the present invention, as a result of earnestly examining the means for solving the problems of the above-described conventional invention, the bag body that can accommodate the absorbent main body, the skin non-opposing surface side of the absorbent main body, By mounting on the position including the center in the length direction, this bag body not only helps sanitary disposal of the absorbent body after use, but also during use of the absorbent body. The knowledge that it functions to improve the leak-proofing and cushioning properties in the crotch region was obtained. The inventor has conceived that the problems of the prior art can be solved based on the above knowledge, and has completed the present invention.
More specifically, the present invention has the following configuration.

The present invention relates to an absorbent article provided with a bag.
The absorbent article of the present invention includes an absorbent main body 10 and a bag body 20. The bag body 20 is attached to the skin non-facing surface side of the absorbent main body 10 and can store the absorbent main body 10 in an internal space formed by turning it over.
Further, the bag body 20 is attached on the skin non-facing surface side of the absorbent main body 10 and on a position including the center in the length direction of the absorbent main body 10.

  Of the absorbent main body 10 divided into the front body, the back body, and the crotch region as in the above configuration, the bag body 20 that can store the used absorbent main body 10 on the skin non-facing surface side of the crotch region. By attaching the, the bag body 20 functions as a leak-proof sheet for preventing leakage of urine or a cushion member for improving the wearing feeling of the absorbent article even during use of the absorbent article. Thus, in this invention, since the bag body 20 can be utilized also as an element which improves the main function of an absorbent article, the situation where the manufacturing cost of an absorbent article becomes expensive can be avoided.

In the absorbent article of the present invention, the absorbent main body 10 preferably has a top sheet 11, a back sheet 12, and an absorbent body 13.
The top sheet 11 is a liquid-permeable sheet member provided on the skin facing surface side. The back sheet 12 is a liquid-impermeable sheet member provided on the skin non-facing surface side. The absorber 13 is a liquid absorbent member interposed between the top sheet 11 and the back sheet 12.
Moreover, in the absorbent article of the present invention, the bag body 20 preferably has a joining surface 21, a free surface 22, and a side surface 23.
The bonding surface 21 is a surface bonded to the back sheet 12. The free surface 22 is a surface that faces the bonding surface 21. The side surface 23 is a surface that connects the left and right ends of the joining surface 21 and the free surface 22 in the width direction. Moreover, the bag body 20 is bound with one end side in the length direction of the joint surface 21 and the free surface 22, and an opening 24 is formed on the other end side in the length direction. As a result, a space for housing the absorbent main body 10 is formed by the joint surface 21, the free surface 22, and the side surface 23.

The sheet members of the layers come to overlap. The crotch region of the absorbent article is the portion where urine leakage is most likely to occur and the most cushioning is required. As in the above configuration, the bag body 20 is attached to the crotch region of the absorbent article, By stacking the sheet member in three or more layers, it is possible to effectively prevent urine leakage and improve the cushioning property when the absorbent article is worn.

  In the absorbent article of the present invention, the bag body 20 is formed such that the bag binding portion 30 is formed by bonding the joining surface 21 serving as the opening 24 and the end portion in the length direction of the free surface 22 so as to be openable. preferable.

  As described above, the opening 24 of the bag body 20 is bound in advance by the bag binding portion 30, so that the free surface 22 of the bag body 20 is fluttered or wrinkled or twisted when using absorbent articles. Can be prevented. In addition, after using an absorbent article, the bag binding part 30 is opened, the opening part 24 is formed in the bag body 20, and the absorptive main body 10 can be accommodated in the bag body 20 as usual. Further, by forming the bag binding portion 30 in the bag body 20 and sealing the inner space thereof, for example, for some reason, the joining surface between the back sheet 12 of the absorbent main body 10 and the bag body 20 in the crotch region. Even if 21 is torn, urine and feces held in the absorbent body 13 will accumulate in the sealed space of the bag body 20 and prevent such excrement from leaking out of the absorbent article. it can.

  In the absorbent article of the present invention, it is preferable that one or a plurality of tissue papers or wet tissue papers are enclosed in the sealed space in a state where the bag binding portion 30 is formed in the bag body 20.

  When the bag binding portion 30 is formed and sealed in the bag body 20 as in the above configuration, tissue paper or wet tissue paper is sealed in the sealed space in advance so that the absorbent article can be discarded. It is convenient because the wet tissue paper enclosed in the bag body 20 can be taken out and the wearer's body can be wiped or the exchanger's fingers can be wiped. Moreover, even when wet tissue paper is sealed in the bag body 20, it is possible to prevent the wet tissue paper from drying by sealing the inside with the bag binding portion 30. Moreover, if tissue paper etc. are enclosed in the bag body 20, since such tissue paper etc. function as a cushion member, the cushioning property in the crotch region of an absorbent article improves. Further, as described above, even if the bonding surface 21 between the back sheet 12 of the absorbent main body 10 and the bag body 20 is torn in the crotch region for some reason, if tissue paper or the like is sealed in the bag body 20, Since this tissue paper or the like functions as a leak-proof member, excrement such as urine can be prevented from leaking outside.

  In the absorbent article of the present invention, the bag body 20 is preferably formed of a liquid-impermeable material.

  By forming the bag body 20 from a liquid-absorbing material such as polyethylene or polypropylene as in the above configuration, the effect of preventing leakage by the bag body 20 is enhanced.

  As described above, according to the present invention, the bag body for rolling up and storing the absorbent main body so that the disposal treatment after use can be performed in a sanitary manner can be performed not only when the absorbent article is discarded, Even when wearing a functional article, it can be used as a member that enhances its leak-proofing and cushioning properties.

The resulting bag 20 may be fused to the absorbent main body 10 at the joint 25 by heat sealing, ultrasonic sealing, or the like. Further, the free surface 22 is not fixed to the absorbent main body 10 as a whole, but can be moved freely. However, as shown in FIG. 1, the free surface 22 of the bag body 20 is joined to the absorbent main body 10 together with the joint surface 21 at the joint portion 25 in the vicinity of one end edge in the length direction. It is in a state. Thereby, a bag-shaped space is formed by the joint surface 21, the free surface 22, and the side surface 23. On the other hand, in this embodiment, the joining portion 25 is not provided on the other end in the length direction of the free surface 22 and is open. Thereby, the other end side in the length direction of the free surface 22 becomes the opening 24 of the bag body 20.

  Further, as described above, in the present invention, the bonding surface 21 of the bag body 20 is at least the non-skin facing surface of the absorbent main body 10 and is attached on the center in the length direction. Good. Further, the absorbent main body 10 is divided into three so that the lengths in the length direction are equal, the region on the side corresponding to the wearer's abdomen is the front body 10A, and the region on the side corresponding to the wearer's back is the rear. When the body 10B is used and the region located between the front body and the back body is a crotch region 10C, the bag body 20 includes the crotch region 10C and is attached to a region covering the front body 10A and the back body B. Preferably it is. For example, the length of the joining surface 21 in the bag body 20 in the length direction is preferably 35% to 90%, assuming that the length in the length direction of the absorbent main body 10 is 100%, and 40% It is especially preferable to set it to -60%. However, the bag body 20 can be attached only in the crotch region 10C of the absorbent main body 10.

  In addition, as shown in FIG. 1, it is preferable that the length in the width direction of the bonding surface 21 in the bag body 20 substantially coincides with the length in the width direction of the absorbent main body 10. More specifically, the length in the width direction of the joint surface 21 in the bag body 20 is 80% to 100%, or 85% to 95, where the length in the width direction of the absorbent main body 10 is 100%. % Is preferred.

  As a material for forming the bag body 20, a known liquid-impermeable material can be employed. The liquid-impermeable material means, for example, a material that does not permeate the water even after 1 minute or more when 5 ml of room temperature water is placed thereon under a standard atmospheric pressure. For example, it is preferable to use a bag 20 made of a thermoplastic resin such as polyethylene or polypropylene.

  FIG. 2 is a plan view of the absorbent article. Fig.2 (a) has drawn the skin opposing surface side of the absorbent article, and FIG.2 (b) has drawn the skin non-opposing surface side of the absorbent article. FIG. 3 is a cross-sectional view taken along line AA in FIG. Here, with reference to FIG.2 and FIG.3, each part structure of the absorptive main body 10 is demonstrated.

  In the present embodiment, the absorbent main body 10 will be described by taking a so-called urine absorption pad as an example. However, the configuration of the absorbent main body 10 is not limited to that described below, and a configuration used for a known absorbent article can be appropriately employed. For example, the absorbent main body 10 is worn for the purpose of absorbing and holding body fluids, such as pants-type disposable diapers, tape-type disposable diapers, absorbent pads, sanitary napkins, as well as urine pads. It is possible to apply the configuration of the article worn by the person.

  2 and 3, the absorbent main body 10 includes a top sheet 11, a back sheet 12, an absorber 13, a leg gather elastic member 14, a pair of side sheets 15, and a three-dimensional gather elastic member. 16.

  The top sheet 11 is a member that is in direct contact with the skin of the wearer's crotch and allows liquid such as urine to pass through the absorber 13. For this reason, the top sheet 11 is made of a liquid-permeable material having high flexibility. Moreover, the top sheet 11 is arrange | positioned so that the skin opposing surface side of the absorber 13 may be coat | covered. The liquid-permeable material means, for example, a material that permeates water in a time of less than 1 minute when 5 ml of room temperature water is placed thereon under a standard atmospheric pressure. Examples of the liquid permeable material constituting the top sheet 11 are a woven fabric, a non-woven fabric, or a porous film. Further, for example, a fiber made of a thermoplastic resin such as polypropylene, polyethylene, polyester, or nylon, which has been subjected to a hydrophilization treatment and further made into a non-woven fabric may be used.

  The back sheet 12 is a member for preventing the liquid that has passed through the top sheet 11 and absorbed by the absorber 13 from leaking to the outside. For this reason, the back sheet 12 is made of a liquid-impermeable material. The back sheet 12 is disposed so as to cover the skin non-facing surface side of the absorber 13 in order to prevent liquid leakage from the absorber 13. An example of the liquid-impermeable material constituting the back sheet 12 is a liquid-impermeable film made of polyethylene resin. In particular, it is preferable to use a microporous polyethylene film in which a plurality of fine pores of 0.1 to 4 μm are formed. Further, as shown in the cross-sectional view of FIG. 3, in the present embodiment, the bonding surface 21 of the bag body 20 is bonded to the non-skin facing surface of the back sheet 12. For this reason, at least the three-layer liquid-impermeable sheet of the back sheet 12, the bonding surface 21 of the bag body 20, and the free surface 22 of the bag body 20 overlaps with the skin non-facing surface side of the absorbent body 13. Become. Thereby, the leak-proof property in the crotch region of the absorptive main body 10 increases. In addition, although illustration is abbreviate | omitted, it is good also as sticking together the cover sheet formed with the nonwoven fabric etc. on the non-skin opposing surface of the back sheet 12 for the purpose of improving the touch of the back sheet 12.

  Further, as shown in FIG. 3, in the present embodiment, the back sheet 12 has a length that extends to the left and right outer sides of the absorber 13 in the width direction while covering the entire bottom surface of the absorber 13. Further, the length of the back sheet 12 in the width direction is longer than the length of the top sheet 11 in the width direction. A portion of the back sheet 12 that extends to the left and right outer sides of the absorbent body 13 is folded back to the skin facing surface side of the absorbent body 13.

  The absorber 13 is a member for absorbing liquid such as urine and holding the absorbed liquid. The absorber 13 is disposed between the liquid-permeable top sheet 11 and the liquid-impermeable back sheet 12. The absorber 13 is made of an absorbent material having a function of absorbing a liquid such as urine. A well-known material can be employ | adopted for the absorptive material which comprises the absorber 13. FIG. As an absorptive material, for example, one kind of pulverized pulp (fluff pulp), a superabsorbent polymer, or a hydrophilic sheet may be used alone, or two or more kinds may be used in combination. The absorbent material is usually used in the form of a single layer or a plurality of layers.

  The leg gather elastic members 14 are members that are arranged on the left and right sides of the absorbent body 13 in the width direction and form leg gathers at positions corresponding to the circumference of the wearer's legs. In the present embodiment, the leg gather elastic member 14 is fixed in an extended state to a portion of the backsheet 12 that extends to the left and right outer sides of the absorber 13. When the leg gather elastic member 14 contracts, the back sheet 12 bends to form a leg gather.

  In addition, a three-dimensional gather is formed by the pair of side sheets 15 disposed on both the left and right sides of the absorbent body 13 and the three-dimensional gather expansion / contraction member 16 joined in the extended state near the tip of the side sheet 15. The side sheets 15 are joined to the skin facing surface side of the top sheet 11 at both ends of the front body side and the back body side. Further, the side sheet 15 has a free end that is not joined to the top sheet 11 at the center in the length direction including the crotch region. Further, the pair of side sheets 15 are folded back at the free ends to the inner side in the width direction or the outer side in the short direction of the absorber 13, and one or a plurality of stretched three-dimensional gather elastic members 16 are stretched at the folded portions. It is clamped and fixed by. For this reason, as the three-dimensional gather expansion / contraction member 16 contracts, the pair of side sheets 15 rises along both side edges of the absorbent body 13 and serves as a three-dimensional gather to prevent side leakage of urine excreted by the wearer. Function. As a material constituting the pair of side sheets 15, it is preferable to use a sheet material having water repellency. As an example of the material of the side sheet 15, it is preferable to use a nonwoven fabric such as spunbond or card emboss from the viewpoint of high water repellency and good air permeability.

  Moreover, a well-known elastic elastic member can be used for the leg gather elastic member 14 and the three-dimensional gather elastic member 16 described above. For example, thread elastic rubber or flat elastic rubber can be applied to each elastic elastic member. As such a rubber member, materials such as styrene rubber, olefin rubber, urethane rubber, ester rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicone, or polyester can be used.

Subsequently, FIG. 4 shows an example of a state in which the absorbent main body 10 is stored inside the bag body 20, as shown in FIG. The absorbent main body 10 is folded into the internal space formed by turning the bag body 20 upside down so that the absorbent main body 10 is rolled up while the bag body 20 attached to the opposite surface side is turned over. The internal space of the bag 20 is defined by the joint surface 21, the free surface 22, and the side surface 23. It is preferable that the bonding surface 21 and the free surface 22 of the bag body 20 are bonded to each other with an adhesive tape 26 or the like after the absorbent main body 10 is stored in the bag body 20 so as not to protrude from the internal space of the bag body 20. . This adhesive tape 26 may be previously attached to the bonding surface 21 and the free surface 22 of the bag body 20, or may be provided separately. The absorbent main body 10 can be accommodated in the bag body 20 by attaching the adhesive tape 26 or the like and closing the internal space of the bag body 20. The form which accommodates the absorptive main body 10 in the bag body 20 can be used in various scenes. For example, what is necessary is just to accommodate in the bag body 20, when discarding the absorptive main body 10 which absorbed the wearer's excrement. Further, for example, when the absorbent main body 10 before use is individually conveyed, it can be stored in the bag body 20.

  Further, as shown in FIG. 4, it is preferable that the inner surface and the outer surface of the bag body 20 have different colors. “Different colors” means that at least one of brightness, hue, and saturation is different. In addition, not only colors with different hues but also colors with the same hue, but with intentionally different saturation or lightness shall be “different colors”. As described above, the inner surface color and the outer surface color of the bag body 20 are different from each other, so that it is easy to distinguish the front and back of the bag body 20, which is convenient when the absorbent main body 10 is stored inside the bag body 20. is there.

  Next, a second embodiment of the absorbent article according to the present invention will be described with reference to FIG. In the second embodiment shown in FIG. 5, the same components as those in the first embodiment described above are denoted by the same reference numerals, and the description thereof is omitted, and the differences from the first embodiment described above are different. The explanation will be given mainly.

  Fig.5 (a) is a perspective view which shows the state which looked at the absorbent article 100 which concerns on 2nd Embodiment from the skin non-opposing surface side. FIG. 5A particularly shows a state in which the bonding surface 21 and the free surface 22 of the bag 20 are bonded in advance so as to be openable and the opening 24 is bound. That is, at the position where the opening 24 is to be formed in the bag body 20, the joint surface 21 and the free surface 22 are bonded so as to be openable, thereby forming the bag binding portion 30. In the bag binding part 30, what is necessary is just to adhere | attach the joining surface 21 and the free surface 22 of the bag body 20 so that peeling is possible using a well-known apparatus. For example, a seal process may be applied to the vicinity of the opening 24 of the bag body 20 using a heat seal device or an ultrasonic sealing device, or an adhesive may be applied to the vicinity of the opening 24 of the bag body 20. It is good also as sealing this opening part 24 by apply | coating. As shown in FIG. 5A, the opening portion 24 of the bag body 20 is bound by the bag binding portion 30, whereby the inside of the bag body 20 becomes a sealed space. The sealed space is a space in which the interior of the bag body 20 is completely surrounded by the joining surface 21, the free surface 22, and the side surface 23, and as a result, liquid and air do not pass through the interior.

  FIG. 5B shows a state where the bag body 20 is opened at the bag binding portion 30 shown in FIG. 5A and an opening 24 is formed in the bag body 20. As shown in FIG. 5 (b), by breaking the bag binding portion 30, the bonding state of the joint surface 21 and the free surface 22 of the bag body 20 is released, and the opened portion is replaced with the opening portion 24. Become.

  Further, as shown in FIG. 5B, sanitary paper 31 such as tissue paper or wet tissue paper may be sealed in the sealed space of the bag body 20. As the sanitary paper 31 such as tissue paper or wet tissue paper, a commercially available publicly known paper may be used. Moreover, the sanitary paper 31 enclosed in the bag body 20 may be one sheet or a plurality of sheets. In this way, when the bag binding portion 30 is formed and sealed in the bag body 20, the sanitary paper 31 is sealed in the sealed space in advance, so that when the absorbent article is discarded, This is convenient because the sanitary paper 31 enclosed in the bag can be taken out and the wearer's body can be wiped or the finger of the exchanger can be wiped. Further, even when wet tissue paper containing moisture is enclosed in the bag body 20, for example, the wet tissue paper can be prevented from drying by sealing the inside with the bag binding portion 30. Moreover, if tissue paper etc. are enclosed in the bag body 20, since such tissue paper etc. function as a cushion member, the cushioning property in the crotch region of an absorbent article improves.
