Description
【０００１】[0001]
本考案は、吸収体厚肉部（立体部）を有する生理用ナプキンに係り、特に着用 者へのフィット性を良好とする生理用ナプキンに関する。 The present invention relates to a sanitary napkin having a thick-walled portion (three-dimensional portion) of an absorbent body, and more particularly to a sanitary napkin having a good fit to a wearer.
【０００２】[0002]
生理用ナプキンに要求される品質としては、装着時に股間によくフィットする ことが重要である。図１０に示される、従来より供されている生理用ナプキン２ ０における排液の吸収・保持のための吸収体は、半剛性体である綿状パルプが、 平板状に使用面の前面に均一に入っているか、もしくは長手方向の両端まで入っ ていた。 一方、近年、スポット吸収性を高めるために吸収体の排液部に相当する部分を 二層構造とした生理用ナプキンが提案されている。 A good quality of a sanitary napkin is that it fits well between the groins when worn. As shown in FIG. 10, the absorbent body for absorbing and holding the drainage in the conventionally used sanitary napkin 20 is a semi-rigid cotton-like pulp, which is flat and evenly formed on the front surface of the use surface. It was either inside, or it was inside both ends in the longitudinal direction. On the other hand, in recent years, a sanitary napkin has been proposed in which the part corresponding to the drainage part of the absorbent body has a two-layer structure in order to enhance the spot absorbency.
【０００３】[0003]
しかしながら、前記した平板状のナプキン２０の場合、着用者の逆Ｕ字状の股 間部分に当てがわれた際に、着用者の股間巾にナプキンの巾が合っていないと装 着時に図１１に示されるように内股からの圧縮力により縦方向にヨレ・シワが生 じることが多かった。仮に、股間巾にナプキンの巾が合っていたとしても、着用 者の激しい動きによって次第にヨレが生じ、同様の結果を招いていた。また、前 記ヨレ・シワによってできた隙間から排液の漏れが生じるとともに、片ヨレ等の ために装着感も悪いものとなっていた。 また、吸収体排液部が二層構造の生理用ナプキンの場合、単に厚みを増したの では、吸収性が上がるものの、ゴワツキ感がでて装着感を損なうこととなる。 However, in the case of the flat plate-shaped napkin 20 described above, when the napkin is fitted to the wearer's inverted U-shaped crotch part and the crotch width of the wearer does not match the width of the napkin, the napkin shown in FIG. As shown in Fig. 5, the compressive force from the inner thigh often caused vertical wrinkles and wrinkles. Even if the width of the napkin fits the width of the crotch, the wearer's violent movement gradually causes a twist, which causes the same result. In addition, the drainage leaked from the gap created by the twisting and wrinkling described above, and due to the one-sided twisting and the like, the feeling of wearing was also poor. Further, in the case of a sanitary napkin having a two-layer structure for the absorbent drainage part, if the thickness is simply increased, the absorbability is increased, but the feeling of stiffness is felt and the wearing feeling is impaired.
【０００４】 そこで、本考案の主たる課題は、吸収体排液部を厚肉とする生理用ナプキンに 係り、着用時における吸収体のヨレ・シワを無くすとともに、フィット性の優れ た生理用ナプキンを提供するものである。Therefore, the main problem of the present invention relates to a sanitary napkin having a thick absorbent body drainage part, which eliminates wrinkles and wrinkles of the absorbent body when worn and which has a good fit. It is provided.
【０００５】[0005]
前記課題は、透液性シートと、不透液性シートと、両シート間に介装される排 液を吸収する吸収体とを備えた実質的に細長形状の生理用ナプキンにおいて、 前記吸収体中間の排液部を厚肉とするとともに、該厚肉部の吸収体断面積を４ ００mm2 〜７００mm2 とし、かつ使用面側に膨出した断面形状としたことで解決 できる。また、好ましくは前記吸収体の厚肉部断面積を５００mm2 〜７００mm2 かつその巾寸法を３０mm〜７０mmとする。さらに、吸収体中間の両側部のサイド フラップ部にナプキン長手方向に沿って、生理用ナプキンの製品長の１／３以上 の長さを有し、かつ該弾性伸縮部材配設範囲に製品状態で１０〜３０％の収縮率 を与える弾性伸縮部材を設ける。The problem is a substantially elongated sanitary napkin including a liquid-permeable sheet, a liquid-impermeable sheet, and an absorbent body that is interposed between the sheets and that absorbs drainage. an intermediate drainage portion with a thick, the absorbent cross-sectional area of the thick portion and the 4 00mm 2 ~700mm 2, and can be solved by having a cross-sectional shape that bulges to the use surface side. Further, preferably, the cross-sectional area of the thick portion of the absorber is 500 mm 2 to 700 mm 2 and the width dimension thereof is 30 mm to 70 mm. In addition, the side flaps on both sides in the middle of the absorbent body have a length of ⅓ or more of the product length of the sanitary napkin along the longitudinal direction of the napkin, and are in a product state within the elastic expansion / contraction member disposition range. An elastic stretchable member that provides a shrinkage of 10 to 30% is provided.
【０００６】[0006]
本考案に係る生理用ナプキンにおいては、吸収体排液部分、すなわち股間部相 当部位の吸収体は他の部分より厚肉とされるとともに、その断面形状は、その使 用面側が、たとえば円形または楕円に膨出した形状とされる。したがって、逆Ｕ 字状の股間部分に当初よりフィットした形で装着されるとともに、内股からの圧 力によっても巾方向のヨレを生じることが無くなるとともに、長手方向の隙間も 生じないため漏れを効果的に防止できる。吸収体排液部の吸収体断面積は、本考 案が望む膨出形状の吸収体とするために、４００mm2 〜７００mm2 、好ましくは ５００mm2 〜７００mm2 であって、かつその巾寸法を３０mm〜７０mmとされる。In the sanitary napkin according to the present invention, the absorbent drainage portion, that is, the absorbent body at the crotch-corresponding portion is made thicker than the other portions, and its cross-sectional shape is, for example, circular on the side of its use surface. Alternatively, the shape is bulged into an ellipse. Therefore, it is fitted to the inverted U-shaped crotch part from the beginning, and it is possible to prevent leakage in the width direction due to the pressure force from the inner crotch and to prevent leakage in the longitudinal direction. Can be prevented. Absorbent cross-sectional area of the absorber effluent portion, to the absorber of the bulge shape the devised wishes, 400mm 2 ~700mm 2, preferably a 500mm 2 ~700mm 2, and the width dimensions It is set to 30 mm to 70 mm.
【０００７】 また、サイドフラップ部に、生理用ナプキンの製品長の１／３以上の長さを有 し、かつ該弾性伸縮部材配設範囲に製品状態で１０〜３０％の収縮率を与える弾 性伸縮部材を設けることにより、十分な長さに渡って配設された弾性伸縮部材の 収縮力が、吸収体の厚肉部全体に渡って効果的に作用し、吸収体の厚肉部を含め て、ナプキンの長手方向全体に渡って舟形に湾曲させるため、前後方向にもフィ ットさせることができる。Further, the side flap portion has a length which is ⅓ or more of the product length of the sanitary napkin, and which gives a contraction rate of 10 to 30% in the product state in the elastic elastic member disposition range. By providing the elastic stretchable member, the shrinkage force of the elastic stretchable member arranged over a sufficient length effectively acts on the entire thick portion of the absorber, and In addition, since it is curved in a boat shape over the entire length of the napkin, it can be fitted in the front-back direction.
【０００８】[0008]
次に、実施例に基づいて本考案を詳細に説明する。 図１は、生理用ナプキンを使用面側から見た平面図であり、装着時には図１の 上方が腹側で、下方側が背側となる。同図において、１は不織布または孔開きプ ラスチックシートなどからなる透液性シートであり、２はポリエチレンシートな どからなる不透液性シートであり、その間に吸収体３が介装されている。このナ プキンの平面形状は全体として細長く、吸収体３の長手方向中央部分、すなわち 股間相当部分が若干括れている。 Next, the present invention will be described in detail based on embodiments. FIG. 1 is a plan view of the sanitary napkin as seen from the side of the use surface, and the upper side of FIG. 1 is the abdominal side and the lower side is the dorsal side when worn. In the figure, 1 is a liquid-permeable sheet made of non-woven fabric or perforated plastic sheet, and 2 is a liquid-impermeable sheet made of polyethylene sheet or the like, and an absorber 3 is interposed therebetween. . The planar shape of this napkin is elongated as a whole, and the central portion of the absorbent body 3 in the longitudinal direction, that is, the portion corresponding to the crotch is slightly constricted.
【０００９】 また、透液性シート１と不透液性シート２は、吸収体３の周縁から外方に延在 して、両シート１、２がホットメルトなどの接着剤またはヒートシールなどによ り重ね合わされ、フラップ部Ｆが形成されている。不透液性シート２の下面には 、ズレ止めホットメルト接着剤７が適宜のパターンで塗布されており、これは剥 離紙８により被服されている。装着時には、この剥離紙８を剥離し、ホットメル ト接着剤７部分をショーツに圧着させて、ナプキンのズレ止めを図っている。Further, the liquid-permeable sheet 1 and the liquid-impermeable sheet 2 extend outward from the peripheral edge of the absorbent body 3 so that both sheets 1 and 2 can be used as an adhesive such as hot melt or heat seal. And the flap portion F is formed. On the lower surface of the liquid-impervious sheet 2, a slip-preventing hot melt adhesive 7 is applied in an appropriate pattern, which is covered with a release paper 8. At the time of mounting, the release paper 8 is peeled off, and the hot melt adhesive 7 portion is pressed against the shorts to prevent the napkin from being displaced.
【００１０】 前記吸収体３は、図２の横断面図に示されるように、上部吸収体３１と下部吸 収体３２との二重構造となっている。下部吸収体３２は、ナプキン長手方向中間 部であって幅方向中間部分に設けられ、吸収体３の排液部のみを厚肉部Ｄとして いる。なお、図２では、構造の説明のために平板状に吸収体３を描いているが、 実際の製品状態では、側部に配設された弾性伸縮部材４、４の圧力作用を受け、 図３に示されるように、フリーな状態（製品状態）で厚肉部を使用面側に円弧状 に膨出させた中高部Ｎが形成されている。かかる吸収体断面形状とすることで、 図８に示される使用状態で、着用者の逆Ｕ字状の股間形状Ｋにフィットさせるこ とができ、内股からの力が作用してもヨレやシワが生じない構造となっている。The absorbent body 3 has a double structure of an upper absorbent body 31 and a lower absorbent body 32, as shown in the cross-sectional view of FIG. The lower absorbent body 32 is provided in the widthwise intermediate portion of the napkin in the longitudinal direction, and only the drainage portion of the absorbent body 3 is the thick portion D. Note that, in FIG. 2, the absorber 3 is drawn in a flat plate shape for the purpose of explaining the structure, but in an actual product state, it is subjected to the pressure action of the elastic expansion / contraction members 4 and 4 arranged on the side portions, and As shown in FIG. 3, a middle height portion N is formed in a free state (product state) in which the thick portion is bulged in an arc shape on the use surface side. By adopting such an absorbent body cross-sectional shape, it is possible to fit the wearer's inverted U-shaped crotch shape K in the use state shown in FIG. 8, and even when force from the inner crotch acts, twisting or wrinkling occurs. The structure does not occur.
【００１１】 また、ヨレやシワが生じない結果、排液漏れを効果的に防止することができる。Further, as a result of no twisting or wrinkling, drainage leakage can be effectively prevented.
【００１２】 なお、前記吸収体排液部の断面形状としては、たとえば図７に示されるように、 平板状の下部吸収体１０の上に断面凸状の状部吸収体１１を積層し、使用面側を 膨出させることでもよい。また、この二重構造によれば、経血が排出される部分 の吸収体の総量が多いので吸収性能が高まる。また、上部吸収体３１と下部吸収 体３２は、その形態保持力の補強のために、テッシュなどからなる紙綿台紙９等 によって被包することができる。なお、透液性シート１と吸収体３または紙綿台 紙９とは平面的にスパイラル状態に塗布したホットメルト接着剤により接合する ことができる。As for the cross-sectional shape of the absorbent drainage part, as shown in FIG. 7, for example, a plate-shaped lower absorbent body 10 is laminated with a convex-shaped absorbent body 11 having a cross-section and is used. It is also possible to bulge the surface side. Further, according to this double structure, since the total amount of the absorber in the portion where menstrual blood is discharged is large, the absorption performance is improved. Further, the upper absorbent body 31 and the lower absorbent body 32 may be wrapped with a paper cotton backing paper 9 made of tissue or the like in order to reinforce the shape retaining force. The liquid-permeable sheet 1 and the absorber 3 or the paper backing paper 9 can be joined by a hot-melt adhesive applied in a planar spiral state.
【００１３】 本考案に係る生理用ナプキンにおいては、前記厚肉部の吸収体断面積は、４０ ０mm2 〜７００mm2 、好ましくは５００mm2 〜７００mm2 であってかつその巾寸 法Ｂs が３０mm〜７０mmとされ、ナプキンの製品状態においては、図３に示され るように、使用面側が膨出した楕円形状に成形される。排液部の吸収体断面積が ４００mm2 未満の場合には、体積が少な過ぎて排液部の吸収体を股間形状Ｋに合 った膨出形状に成形することができず、また７００mm2 を超えると体積が多すぎ て違和感を伴い装着感の悪いものとなってしまう。また、前記厚肉部Ｄの総厚Ｔ0 は１０〜２５mm、好ましくは１２〜１８mmの範囲とするのが望ましく、またそ れ以外の一般部分の厚みＴ1 は２〜１０mm、好ましくは２〜６mmの範囲とするの がよい。なお、吸収体の前記厚さＴ0 、Ｔ1 の決定に当たっては昼用と夜用とを 考慮し、昼用は装着感に重きを置き、夜用については前後漏れに重きをおいて、 前記範囲内で適宜決定するのが望ましい。ただし、一般部分の厚みＴ1 を薄くす る場合には、違和感および携帯性の点からは好ましいのであるが、吸収体自体に コシがなくなり、弾性伸縮部材４による収縮を受けて横ジワが入り易くなるとと もに、手触りでの厚感がなくなるため、紙綿にパルプ不織布を混入したものを使 用すると薄い場合であっても程よい剛性を付与することができる。また、水溶性 高分子樹脂バインダーやホットメルト接着剤を散布するなどにより剛性を付与す ることもできる。[0013] In the sanitary napkin according to the present invention, the absorbent cross-sectional area of the thick portion, 40 0mm 2 ~700mm 2, is preferably a 500mm 2 ~700mm 2 and its Habasun method B s 30 mm In the product state of the napkin, as shown in FIG. 3, the napkin is molded into an elliptical shape with a bulged surface. When the cross-sectional area of the absorber in the drainage part is less than 400 mm 2 , the volume of the absorber in the drainage part is too small to form a bulging shape that fits the crotch shape K, and 700 mm 2 If it exceeds, the volume will be too large and the user will feel uncomfortable and feel uncomfortable. Further, the total thickness T 0 of the thick portion D is preferably in the range of 10 to 25 mm, preferably 12 to 18 mm, and the thickness T 1 of other general portions is 2 to 10 mm, preferably 2 to A range of 6 mm is recommended. In determining the thicknesses T 0 and T 1 of the absorber, taking into consideration daytime and nighttime use, the daytime wear should be attached to the feeling of wearing, and the nighttime use should be focused on front and rear leakage. It is desirable to appropriately determine within the range. However, it is preferable to reduce the thickness T 1 of the general part from the viewpoint of discomfort and portability, but the absorbent body itself loses its elasticity and contracts by the elastic expansion / contraction member 4, causing lateral wrinkles. At the same time, it is easy to feel, and since the feeling of touch is lost, the use of a paper cotton mixed with a pulp non-woven fabric can impart appropriate rigidity even when it is thin. Also, rigidity can be imparted by spraying a water-soluble polymer resin binder or a hot melt adhesive.
【００１４】 前記厚肉部の両側部分であって、やや腹側寄りのサイドフラップ部Ｆにおいて 、透液性シート１と不透液性シート２との間に弾性伸縮部材４が介装され、その 伸長状態においてホット接着剤により固着一体化されている。弾性伸縮部材４と しては、１本または平行の複数本の糸ゴム、または帯状のゴム、あるいはウレタ ンなどの弾性発泡帯などを用いることができる。 前記弾性伸縮部材４は、その収縮力により、図４に示されるように、半剛性体 たる二重構造の吸収体３を長手方向に舟形に湾曲させ、身体にフィットさせると ともに、横漏れおよび前後漏れを防止する。配設される弾性伸縮部材４の弾性伸 縮部材長Ｘと吸収体３の厚肉部長さＳとの相対的関係は図示されるように、弾性 伸縮部材長さＸは厚肉部長さＳよりも長くされ、厚肉部Ｄの長手方向形成範囲は 前記弾性伸縮部材４の配設範囲内とされる。これにより、厚肉部分Ｄをも含めて 強制的に屈曲させ厚肉部分Ｄのフィット性も良好としている。前記弾性伸縮部材 長さＸと厚肉部長さＳとの相対差は、大きすぎると非中高部分にシワを作ってし まい、逆に隙間の原因ともなるため、厚肉部Ｄの前後側のそれぞれに０〜２０mm 、好ましくは６〜１２mm程度の余裕を持たせるようにして弾性伸縮部材長さＸを 決定するのが望ましい。At the side flaps F, which are on both sides of the thick portion and are slightly abdominal, elastic elastic members 4 are interposed between the liquid-permeable sheet 1 and the liquid-impermeable sheet 2. In the stretched state, they are fixed and integrated with a hot adhesive. As the elastic expansion / contraction member 4, one or a plurality of parallel rubber threads, band-shaped rubber, or elastic foam band such as urethane can be used. As shown in FIG. 4, the elastic expansion / contraction member 4 causes the absorbent body 3 having a double structure, which is a semi-rigid body, to be curved in a boat shape in the longitudinal direction so as to fit the body and to prevent side leakage and Prevent front-to-back leakage. As shown in the figure, the elastic expansion / contraction member length X of the elastic expansion / contraction member 4 and the thick wall portion length S of the absorber 3 are relative to each other. The lengthwise forming range of the thick portion D is set within the range in which the elastic expansion / contraction member 4 is provided. As a result, the thick portion D is forcibly bent, and the thick portion D also has a good fit property. If the relative difference between the length X of the elastic member and the length S of the thick portion is too large, wrinkles may not be formed in the non-middle height portion, and on the contrary, it may cause a gap. It is desirable to determine the elastic expansion / contraction member length X so that each has a margin of 0 to 20 mm, preferably 6 to 12 mm.
【００１５】 一方、吸収体３の排液部からの漏れを効果的に防ぐためには、吸収体３を長手 方向に舟形に成形するとともに、図３に示されるように、吸収体３の両側部のサ イドフラップ部Ｆを立ち上げて、横断面形状をも舟形に成形し、排液部分の全体 をコップ状に成形するのが望ましい。ここで、生理用ナプキン長手方向の舟底部 分を着用者にフィットさせるためには、その長さＬを５０〜７０mm以上とする必 要がある。したがって、本考案における弾性伸縮部材４の長さＸとしては、製品 長Ｍの１／３以上の長さを確保する。好適には、少なくとも前記股間相当部位と なる舟底長さＬ以上の長さを確保することとし、製品フリー状態で７０mm以上、 望ましくは８０mm以上の長さとするのがよい。On the other hand, in order to effectively prevent leakage from the drainage part of the absorbent body 3, the absorbent body 3 is formed into a boat shape in the longitudinal direction, and as shown in FIG. It is desirable that the side flap F of the above is raised and the cross-sectional shape is also formed into a boat shape, and the entire drainage portion is formed into a cup shape. Here, in order to fit the wearer to the boat bottom portion in the longitudinal direction of the sanitary napkin, the length L thereof needs to be 50 to 70 mm or more. Therefore, as the length X of the elastic expansion / contraction member 4 in the present invention, a length of 1/3 or more of the product length M is secured. It is preferable to secure a length of at least the boat bottom length L which is at least the crotch-equivalent portion, and is 70 mm or more, preferably 80 mm or more in the product free state.
【００１６】 また、弾性伸縮部材４の収縮力は、下部吸収体３２を屈曲させるとともに、立 体的に持ち上げて中高部Ｎを形成し、さらに前後端側を舟形に成形するために、 弾性伸縮部材配設長Ｘに製品状態で１０〜３０％の収縮率を与えるように弾性伸 縮部材４を配設する。収縮率が１０％未満であると、前記した本考案生理用ナプ キンが望む形状に成形することができず、また収縮率が３０％を超えると、逆に 横方向にシワを作ってしまいその隙間から横漏れを起こす原因となる。使用する 弾性伸縮部材としては、前述のように、種々のものを使用することができるが、 本実施例においては、着用者への当りの柔らかさ、密着性等を考慮して１４０％ 伸長時パワーが１００〜２００gf/20mm の発泡ウレタン素材を用いている。In addition, the contraction force of the elastic expansion / contraction member 4 causes the lower absorbent body 32 to bend and rise vertically to form the middle high portion N, and further, to form the front and rear end sides into a boat shape. The elastic expansion / contraction member 4 is arranged so as to give a contraction rate of 10 to 30% to the member arrangement length X in a product state. If the shrinkage ratio is less than 10%, the sanitary napkin of the present invention cannot be molded into the desired shape, and if the shrinkage ratio exceeds 30%, wrinkles are formed in the lateral direction. It may cause side leakage from the gap. As the elastic expansion / contraction member to be used, various kinds can be used as described above, but in the present embodiment, in consideration of the softness to the wearer, the adhesion, etc. Uses urethane foam material with power of 100-200gf / 20mm.
【００１７】 なお、上記例では透液性シート１と不透液性シート２との両者でフラップ部Ｆ を全周に形成してあるが、一方のシートを延在させて二重重ねしてフラップ部Ｆ を形成することもできる。In the above example, the flap portion F 1 is formed on the entire circumference of both the liquid-permeable sheet 1 and the liquid-impermeable sheet 2. However, one sheet is extended and double-lapped. The flap portion F 1 can also be formed.
【００１８】 ところで、前記第１の例では、弾性伸縮部材４、４を設けた例について詳述し たが、本考案では弾性伸縮部材４を必須の構成要件とするものではなく、弾性伸 縮部材を有しない生理用ナプキンであっても本考案を適用することができる。 図５において、１は不織布または孔開きプラスチックシートなどからなる透液 性シートであり、２はポリエチレンシートなどからなる不透液性シートであり、 その間に吸収体３が介装されている。 前記吸収体３の排液部分には、厚肉部Ｄが形成されている。この厚肉部Ｄは図 ６に示されるように、他の圧力作用を受けていない無応力状態で、断面楕円状に なるように、予め吸収体製造段階で図示のような形状に製造されており、使用状 態では、図９に示されるように、着用者の逆Ｕ字状の股間形状Ｋにフィットした 状態で着用される。By the way, in the first example, the example in which the elastic expansion / contraction members 4 and 4 are provided has been described in detail. However, in the present invention, the elastic expansion / contraction member 4 is not an indispensable constituent element, and elastic expansion / contraction is not necessary. The present invention can be applied to a sanitary napkin having no member. In FIG. 5, 1 is a liquid-permeable sheet made of non-woven fabric or perforated plastic sheet, and 2 is a liquid-impermeable sheet made of polyethylene sheet or the like, and an absorber 3 is interposed therebetween. A thick portion D is formed in the drainage portion of the absorber 3. As shown in FIG. 6, the thick portion D is preliminarily manufactured in the shape shown in the figure at the absorber manufacturing stage so as to have an elliptical cross section in a stress-free state where no other pressure is applied. In the use state, as shown in FIG. 9, the wearer is worn in a state fitted to the wearer's inverted U-shaped crotch shape K.
