Abstract

A wearing article configured in such a manner that no gap is formed between a separation sheet and the skin of the wearer. A diaper (1) includes a chassis (10), a liquid absorbing structure (20) located on the chassis (10) on the human body side thereof, a separation sheet (30), and a pair of leakage barrier cuffs (40). The front and rear edges (31, 32) of the separation sheet (30) are joined to a human body-side liner (22) at positions in front and rear waist regions (11, 12), and the remaining portion of the separation sheet (30) is adapted to be separable from the liner (22). Front-rear communication sections (35, 36) separated from each other by an intermediate portion (34) are formed in the separation sheet (30), and elastic bodies (38) for the separation sheet which extend in the longitudinal direction (Y) are mounted to the separation sheet (30). When the elastic bodies (38) for the separation sheet contract, the separation sheet (30) is separated from the liquid absorbing structure (20) to form a space therebetween. A partition sheet (70) for partitioning the space into the front part and the rear part is formed between the separation sheet (30) and the liquid absorbing structure (20). A variable shape member (80) is formed at the other end (72) of the partition sheet (70).

　この発明は、着用物品に関し、さらに詳しくは使い捨てのおむつ、排泄トレーニングパンツ、失禁ブリーフ等に関する。 The present invention relates to a worn article, and more particularly to a disposable diaper, excretion training pants, an incontinence brief, and the like.
　従来、使い捨てのおむつにおいて、便および尿を通過させる開口部が形成されたシートをトップシートの上にさらに有するものが公知である。例えば、特開２００７－１０５２９８号公報（特許文献１）によれば、おむつはトップシートと、バックシートと、これらシート間に位置する吸収体と、トップシートの上部に配置されるスキンコンタクトシートとを有している。スキンコンタクトシートには、便通過用開口部と尿通過用開口部とを形成し、これら開口部間には中央領域が形成されている。スキンコンタクトシートには開口部伸縮材が伸長状態で取り付けられ、この開口部伸縮材の収縮力によってスキンコンタクトシートがトップシートから離間して、着用者の肌に接触するようにしている。スキンコンタクトシートを着用者の肌に接触させることによって、着用者に便等が付着するのを防止している。 Conventionally, it is known that disposable diapers further have a sheet on the top sheet with an opening through which feces and urine are passed. For example, according to Japanese Patent Application Laid-Open No. 2007-105298 (Patent Document 1), the diaper is a top sheet, a back sheet, an absorber positioned between these sheets, and a skin contact sheet disposed on the top sheet. have. In the skin contact sheet, a fecal passage opening and a urine passage opening are formed, and a central region is formed between the openings. An opening elastic member is attached to the skin contact sheet in an extended state, and the skin contact sheet is separated from the top sheet by the contraction force of the opening elastic material so as to contact the skin of the wearer. By bringing the skin contact sheet into contact with the skin of the wearer, feces and the like are prevented from adhering to the wearer.
特開２００７－１０５２９８号公報（ＪＰ２００７－１０５２９８　Ａ）JP 2007-105298 A (JP 2007-105298 A)
　スキンコンタクトシートは、平面的に着用者の肌に接触するので、これらスキンコンタクトシートと曲線を有する着用者の肌との間にはどうしても隙間が生じてしまう。隙間を介してスキンコンタクトシート上に排泄物が載置された場合には、排泄物の重さでスキンコンタクトシートが押し下げられ、着用者の肌との離間距離をより大きくしてしまう。また、スキンコンタクトシート上の排泄物は、便通過用開口部または尿通過用開口部のいずれに流入するか確定されず、所望の開口部に流入されない可能性がある。この場合には、尿便分離の機能を発揮することができない。 Since the skin contact sheet comes into contact with the wearer's skin in a plane, a gap is inevitably generated between the skin contact sheet and the wearer's skin having a curve. When the excrement is placed on the skin contact sheet via the gap, the skin contact sheet is pushed down by the weight of the excrement, and the distance from the wearer's skin is further increased. Further, it is not determined whether the excrement on the skin contact sheet flows into the feces passage opening or the urine passage opening, and may not flow into the desired opening. In this case, the function of urine / feces separation cannot be exhibited.
　この発明は、離隔シートと着用者の肌との間に隙間が生じるのを防止することができる着用物品を提供することを課題とする。 This invention makes it a subject to provide the wearing article which can prevent that a clearance gap produces between a separation sheet and a wearer's skin.

The portion of the rear leg elastic body 54 that is continuous in the lateral direction X is near the virtual lateral center line QQ, and extends in the lateral direction X on the front waist region 11 side. When the crotch region 13 is contracted in the lateral direction X by such a rear leg elastic body 54, a pocket 55 is formed on the rear waist region 12 side of the rear leg elastic body 54. In the pocket 55, especially by collecting stool, it can be prevented from adhering to or leaking from the skin (see FIGS. 1 and 2).
　吸液構造体２０は、ティッシュペーパ等の吸液拡散シートで包まれる吸液性芯材２１と、吸液性芯材を覆う身体側ライナ２２とを含む。吸液構造体２０は、クロッチ域１３から縦方向Ｙに延びるとともに、その底面側が内面シート１７に接合されている。 The liquid absorbing structure 20 includes a liquid absorbing core material 21 wrapped with a liquid absorbing diffusion sheet such as tissue paper, and a body side liner 22 covering the liquid absorbing core material. The liquid absorbing structure 20 extends from the crotch region 13 in the longitudinal direction Y, and its bottom surface side is joined to the inner surface sheet 17.
　離隔シート３０は、横方向Ｘに延びる前後端縁３１，３２と、縦方向Ｙに延びる両側縁３３とを有し、前後端縁３１，３２は、前後ウエスト域１１，１２において吸液構造体２０の身体側ライナ２２に接合されている。前後端縁３１，３２以外の部分では、身体側ライナ２２に接合されることなく、ライナ２２から離間可能にされている。離隔シート３０は、縦方向Ｙに中間部分３４を介して離間される前後連通部３５，３６が形成されている。中間部分３４は、両側縁３３を有する両側部分３７の間に連なって形成されている。前後連通部３５，３６は、前後端縁３１，３２において開口し、中間部分３４において閉口し、全体としてほぼＵ字形に形成されている。これら前後連通部３５，３６を介して、身体側と吸液構造体２０側とが連通されている。 The separation sheet 30 has front and rear end edges 31 and 32 extending in the horizontal direction X and both side edges 33 extending in the vertical direction Y. The front and rear end edges 31 and 32 are liquid-absorbing structures in the front and rear waist regions 11 and 12. It is joined to 20 body side liners 22. The portions other than the front and rear end edges 31 and 32 can be separated from the liner 22 without being joined to the body side liner 22. The separation sheet 30 is formed with front and rear communication portions 35 and 36 that are separated in the longitudinal direction Y via an intermediate portion 34. The intermediate portion 34 is formed continuously between both side portions 37 having both side edges 33. The front and rear communication portions 35 and 36 open at the front and rear end edges 31 and 32 and close at the intermediate portion 34, and are formed in a substantially U shape as a whole. The body side and the liquid absorption structure 20 side are communicated with each other through the front and rear communication portions 35 and 36.
　離隔シート３０は、身体側に位置する第１シート３０ａと、その反対側である着衣側に位置する第２シート３０ｂとを含み、これら第１および第２シート３０ａ，３０ｂ間において、縦方向Ｙに延びる離隔シート弾性体３８が取り付けられている。離隔シート弾性体３８は、前端縁３１から中間部分３４を介して後端縁３２へと延び、中間部分３４においては、仮想縦中心線Ｐ－Ｐに向かって互いの離間距離を小さくするように湾曲されている。離隔シート弾性体３８は、第１および第２シート３０ａ，３０ｂの少なくともいずれか一方に接合され、伸長状態で収縮可能に取り付けられている。 The separation sheet 30 includes a first sheet 30a located on the body side and a second sheet 30b located on the clothing side, which is the opposite side, and the longitudinal direction Y between the first and second sheets 30a and 30b. A separation sheet elastic body 38 extending in the direction is attached. The separation sheet elastic body 38 extends from the front end edge 31 to the rear end edge 32 via the intermediate portion 34, and in the intermediate portion 34, the separation distance is reduced toward the virtual longitudinal center line PP. It is curved. The separation sheet elastic body 38 is joined to at least one of the first and second sheets 30a and 30b, and is attached so as to be contracted in an extended state.
　図５は、おむつ１のシャーシ１０を省略し、各弾性体が収縮した状態を示したものである。図５および６に示したように、離隔シート弾性体３８が収縮すると、離隔シート３０が吸液構造体２０から離間して、これらの間には空間６０が形成される。離隔シート３０と吸液構造体２０との間には、空間６０を前後に仕切る仕切りシート７０が形成されている。仕切りシート７０は、一端７１が吸液構造体２０の身体側ライナ２２に接合され、他端７２が中間部分３４の着衣側に接合されている。仕切りシート７０は、横方向Ｘの長さ寸法が離隔シート３０の同方向の長さ寸法とほぼ等しくされているので、離隔シート３０が吸液構造体２０から離間された場合には、空間６０を前後に仕切ることができる。 FIG. 5 shows a state where the chassis 10 of the diaper 1 is omitted and each elastic body is contracted. As shown in FIGS. 5 and 6, when the separation sheet elastic body 38 contracts, the separation sheet 30 is separated from the liquid absorbing structure 20, and a space 60 is formed therebetween. A partition sheet 70 that partitions the space 60 forward and backward is formed between the separation sheet 30 and the liquid absorbing structure 20. One end 71 of the partition sheet 70 is joined to the body side liner 22 of the liquid absorbing structure 20, and the other end 72 is joined to the clothing side of the intermediate portion 34. Since the partition sheet 70 has the length dimension in the lateral direction X substantially equal to the length dimension in the same direction of the separation sheet 30, when the separation sheet 30 is separated from the liquid absorbing structure 20, the space 60. Can be divided forward and backward.
　仕切りシート７０の他端７２には、本発明における可変形手段としての可変形部材８０が形成されている。可変形部材８０は、複数枚の繊維不織布の積層体を含み、仕切りシート７０で積層体を包むことによって形成されている。可変形部材８０の横方向Ｘの長さ寸法は、仕切りシート７０の同方向の長さ寸法とほぼ等しくされている。このような可変形部材８０は、離隔シート３０よりも剛性が高く、離隔シート３０の特に中間部分３４が、吸液構造体２０側へと妄りに落ち込むのを防止することができる。また、可変形部材８０は、繊維不織布の積層体を有することによって、それ自体が可撓性を有し、変形可能とされている。可変形部材８０を中間部分３４に接合することによって、中間部分３４にも可撓性を付与することができ、可変形部材８０に追従して変形可能とすることができる。また、可変形部材８０を構成する繊維不織布を透液性とすることによって、可変形部材８０全体を透液性とすることができる。 At the other end 72 of the partition sheet 70, a deformable member 80 is formed as a deformable means in the present invention. The deformable member 80 includes a laminate of a plurality of fiber nonwoven fabrics, and is formed by wrapping the laminate with a partition sheet 70. The length dimension of the deformable member 80 in the lateral direction X is substantially equal to the length dimension of the partition sheet 70 in the same direction. Such a deformable member 80 has higher rigidity than the separation sheet 30, and can prevent the middle portion 34 of the separation sheet 30 from falling into the liquid-absorbing structure 20 side. In addition, the deformable member 80 has a laminated body of fiber nonwoven fabric, so that the deformable member 80 itself has flexibility and can be deformed. By joining the deformable member 80 to the intermediate portion 34, flexibility can be imparted to the intermediate portion 34, and the deformable member 80 can be deformed following the deformable member 80. Further, by making the fiber nonwoven fabric constituting the deformable member 80 liquid-permeable, the entire deformable member 80 can be made liquid-permeable.
　漏れバリアカフ４０は、横方向Ｘに離間して一対形成され、吸液構造体２０の外側に接合されるカフ近位縁４１と、吸液構造体２０の身体側に位置するカフ遠位縁４２と、縦方向Ｙ前後に位置するカフ前後端縁４３，４４とを有する。カフ遠位縁４２では、カフ前後端縁４３，４４の近傍のみが吸液構造体２０に接合され、他の部分では接合されることなく、吸液構造体２０から離間可能とされている。カフ遠位縁４２には、カフ弾性体４５が取り付けられている。カフ弾性体４５は、縦方向Ｙに延びるとともに伸長状態で収縮可能に取り付けられている。
　カフ弾性体４５が収縮すると、吸液構造体２０と接合されていないカフ遠位縁４２が、起立するように吸液構造体２０から離間して、尿等の排泄物が漏れ防止カフ４０の横方向Ｘ外側に漏れるのを防止することができる。 The leak barrier cuff 40 is formed as a pair spaced apart in the lateral direction X, and a cuff proximal edge 41 joined to the outside of the liquid absorbing structure 20 and a cuff distal edge 42 located on the body side of the liquid absorbing structure 20. And cuff front and rear end edges 43 and 44 positioned in the longitudinal direction Y. In the cuff distal edge 42, only the vicinity of the cuff front and rear end edges 43, 44 is joined to the liquid absorbing structure 20, and can be separated from the liquid absorbing structure 20 without being joined in other portions. A cuff elastic body 45 is attached to the cuff distal edge 42. The cuff elastic body 45 extends in the longitudinal direction Y and is attached so as to be contractable in an extended state.
When the cuff elastic body 45 contracts, the cuff distal edge 42 that is not joined to the liquid absorption structure 20 is separated from the liquid absorption structure 20 so as to stand up, and excrement such as urine leaks from the leak prevention cuff 40. It is possible to prevent leakage to the outside in the lateral direction X.
　図７は、図６の状態からおむつ１を着用した状態を示した図であり、着用者の股部を鎖線で示している。図示したように、離隔シート３０が吸液構造体２０から離間して、その中間部分３４が着用者の股下に当接する。中間部分３４の着衣側には可変形部材８０が横方向Ｘに延びているから、この可変形部材８０が着用者の大腿部によって横方向Ｘ内側へと押し付けられる。押し付けられた可変形部材８０は、撓んで身体側へと隆起し、中間部分３４を身体へと密着させることができる。すなわち、中間部分３４を身体側へと押し付けることによって、身体の曲線に沿って中間部分３４を変形させ、これを着用者の身体に密着させて、隙間が生じるのを防止することができる。着用者の身体と離隔シート３０との間に隙間が生じないので、排泄された尿は前連通部３５を介して空間６０に流入され、便は後連通部３６を介して空間６０に流入される。排泄物が離隔シート３０上に排泄されることなく、確実に前後連通部３５，３６に排泄されるので、離隔シート３０が着用者の肌から離れてしまうのを防止することができる。離隔シート３０が、着用者の肌に密着することによって、空間６０に流入された排泄物が肌に付着するのを防止することができる。 FIG. 7 is a view showing a state in which the diaper 1 is worn from the state of FIG. 6, and the crotch portion of the wearer is indicated by a chain line. As shown in the figure, the separation sheet 30 is separated from the liquid absorbing structure 20, and the intermediate portion 34 abuts against the wearer's crotch. Since the deformable member 80 extends in the lateral direction X on the clothing side of the intermediate portion 34, the deformable member 80 is pressed inward in the lateral direction X by the wearer's thigh. The deformable member 80 thus pressed can bend and protrude toward the body side, and the intermediate portion 34 can be brought into close contact with the body. That is, by pressing the intermediate portion 34 toward the body, the intermediate portion 34 can be deformed along the body curve and brought into close contact with the wearer's body, thereby preventing a gap from being generated. Since there is no gap between the wearer's body and the separation sheet 30, the excreted urine flows into the space 60 via the front communication portion 35, and the stool flows into the space 60 via the rear communication portion 36. The Since excrement is reliably excreted by the front and rear communication portions 35 and 36 without being excreted on the separation sheet 30, it is possible to prevent the separation sheet 30 from being separated from the skin of the wearer. When the separation sheet 30 is in close contact with the wearer's skin, the excrement flowing into the space 60 can be prevented from adhering to the skin.
　空間６０は、仕切りシート７０によって前後に仕切られているので、前後連通部３５，３６を介して空間６０に流入した尿および便を分離することができる。
　可変形部材８０は、仕切りシート７０によって包まれ、仕切りシート７０を介して中間部分３４に接合されているので、他の部材で別途包んで接合する場合に比べて、部品点数を少なくすることができ、製造コストの増大を抑制することができる。ただし、必ずしも可変形部材８０は仕切りシート７０を介して中間部分３４に接合される必要はなく、可変形部材８０のみで中間部分３４に接合されていてもよい。この実施形態において、可変形部材８０が変形手段を構成している。 Since the space 60 is partitioned forward and backward by the partition sheet 70, urine and feces that have flowed into the space 60 through the front and rear communication portions 35 and 36 can be separated.
Since the deformable member 80 is wrapped by the partition sheet 70 and joined to the intermediate portion 34 via the partition sheet 70, the number of parts can be reduced as compared with the case of separately wrapped and joined by other members. And an increase in manufacturing cost can be suppressed. However, the deformable member 80 does not necessarily have to be joined to the intermediate portion 34 via the partition sheet 70, and may be joined to the intermediate portion 34 only by the deformable member 80. In this embodiment, the deformable member 80 constitutes a deformation means.
　可変形部材８０が中間部分３４に接合される際、その横方向Ｘの全面で接合されてもよいし、間欠的に接合されてもよい。全面で接合された場合であって、ホットメルト接着剤を使用した場合には、接合部分を撥水性とすることができ、そこに尿が留まるのを防止することができる。また、間欠的に接合された場合には、接合部分の剛性がその他の部分よりも高くなり、これら剛性差によって可変形部材８０を身体側に向かって折れ曲がりやすくすることができる。 When the deformable member 80 is joined to the intermediate portion 34, it may be joined over the entire surface in the lateral direction X or may be joined intermittently. In the case where the entire surface is bonded and a hot melt adhesive is used, the bonded portion can be made water-repellent, and urine can be prevented from staying there. Moreover, when it joins intermittently, the rigidity of a junction part becomes higher than another part, and the deformable member 80 can be easily bent toward the body side by these rigidity differences.
　可変形部材８０は、離隔シート３０の着衣側、すなわち離隔シート３０と吸液構造体２０との間に形成されているが、離隔シート３０の身体側に形成されるようにしてもよい。この場合には、可変形部材８０が直接身体に密着することによって、結果的に離隔シート３０との隙間を解消することができる。また、離隔シート３０の第１および第２シート３０ａ，３０ｂの間に可変形部材８０を形成することとしてもよい。
　可変形部材８０は、中間部分３４に対して完全に一致して重なるように形成されているが、前後連通部３５，３６へと延出してもよい。ただし、可変形部材８０が着用者の肛門を塞ぐことは好ましくないので、少なくとも肛門とは重ならないように取り付けることの望ましい。可変形部材８０の横方向Ｘの長さ寸法は、仕切りシート７０の同方向の長さ寸法とほぼ等しくしているが、これよりも短くてもよい。ただし、中間部分３４の横方向Ｘの長さ寸法よりも長いほうが、横方向Ｘ外側からの押圧を受けやすく、身体側に向かって隆起しやすいので好ましい。 The deformable member 80 is formed on the clothing side of the separation sheet 30, that is, between the separation sheet 30 and the liquid absorbing structure 20, but may be formed on the body side of the separation sheet 30. In this case, the deformable member 80 is in direct contact with the body, and as a result, the gap with the separation sheet 30 can be eliminated. The deformable member 80 may be formed between the first and second sheets 30a and 30b of the separation sheet 30.
The deformable member 80 is formed so as to completely coincide with the intermediate portion 34, but may extend to the front and rear communication portions 35 and 36. However, since it is not preferable that the deformable member 80 closes the wearer's anus, it is desirable to attach the deformable member 80 so as not to overlap at least the anus. The length dimension of the deformable member 80 in the lateral direction X is substantially equal to the length dimension of the partition sheet 70 in the same direction, but may be shorter than this. However, it is preferable that the length of the intermediate portion 34 is longer than the length in the lateral direction X because the intermediate portion 34 is easily pressed from the outside in the lateral direction X and is likely to rise toward the body.
　可変形部材８０には、仮想縦中心Ｐ－Ｐに沿って折曲誘導部を形成することもできる。折曲誘導部としては、例えば、可変形部材８０の身体側またはその反対側に、加熱加圧処理によって凹部を形成することができる。凹部を形成することによって、折曲誘導部が薄くなり折れ曲がりやすくなる。また、加熱加圧処理によって剛性が大きくなり、周囲との剛性差によって折れ曲がりやすくなるということもある。可変形部材８０としては、繊維不織布の積層体のほか、可撓性を有する発泡性ウレタン等を用いることができる。 In the deformable member 80, a bending guide portion can be formed along the virtual longitudinal center PP. As the bending guide portion, for example, a concave portion can be formed on the body side of the deformable member 80 or on the opposite side by heat and pressure treatment. By forming the concave portion, the bending guide portion becomes thin and is easily bent. Moreover, rigidity may become large by heat-pressing process, and it may become easy to bend | fold by the rigidity difference with the circumference | surroundings. As the deformable member 80, in addition to a laminated body of fiber nonwoven fabrics, flexible foamable urethane or the like can be used.

8 and 9 show a second embodiment of the present invention. FIG. 8 is a perspective view of the separation sheet 30 and the deformable member 81 as the deformable means of the present invention, and FIG. 9 is a view similar to FIG. 6, and is a sectional view of the diaper 1 of the second embodiment. is there. In this embodiment, the deformable member is formed on the body side of the separation sheet 30, and the other components are the same as those in the first embodiment. Constituent elements similar to those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and detailed description thereof is omitted.
　離隔シート３０の身体側には、発泡性ウレタン等の柔軟性発泡材料によって形成された可変形部材８１を接合している。可変形部材８１は、中間部分３４に取り付けられ、仮想縦中心線Ｐ－Ｐにおいて最も厚さ寸法が大きくされ、身体側に向かって先細りに形成された先端８１ａと、中間部分３４に取り付けられる底面８１ｂとを有している。先端８１ａは、身体側に向かって湾曲し弧を画いている。 A deformable member 81 formed of a flexible foam material such as foaming urethane is joined to the body side of the separation sheet 30. The deformable member 81 is attached to the intermediate portion 34, and has a distal end 81a that has the largest thickness at the virtual longitudinal center line PP and is tapered toward the body side, and a bottom surface that is attached to the intermediate portion 34. 81b. The tip 81a is curved toward the body side to form an arc.
　このようなおむつ１において、その着用時には、可変形部材８１の先端８１ａが着用者の臀列部に入り込み、さらに、両臀部によって横方向Ｘに押し付けられて、可変形部材８１の全体が着用者の体に沿って変形し、密着する。可変形部材８１が着用者に密着することによって、排泄物が確実に前後連通部３５，３６に流入される。ただし、可変形部材８１は、着用者の肛門よりも前方に位置し、肛門を塞がないようにしている。
　また、離隔シート３０の身体側に可変形部材８１を形成しているので、着用者の身体には可変形部材８１が接触し、離隔シート３０は直接身体に接触しないので、この離隔シート３０による肌への刺激を低減することができる。 In such a diaper 1, when the diaper 1 is worn, the tip 81 a of the deformable member 81 enters the wearer's heel line portion, and is further pressed in the lateral direction X by both heel portions, so that the entire deformable member 81 is worn by the wearer. Deforms along the body and adheres closely. When the deformable member 81 comes into close contact with the wearer, the excrement is surely flowed into the front and rear communication portions 35 and 36. However, the deformable member 81 is positioned in front of the wearer's anus so as not to block the anus.
Further, since the deformable member 81 is formed on the body side of the separation sheet 30, the deformable member 81 contacts the wearer's body, and the separation sheet 30 does not directly contact the body. Skin irritation can be reduced.
　この実施形態において、可変形部材８１が変形手段を構成している。
　可変形部材８１として、発泡性ウレタン等の柔軟性発泡材料を用いているが、繊維不織布の集合体等、他の可撓性の部材を用いることができる。 In this embodiment, the deformable member 81 constitutes a deformation means.
As the deformable member 81, a flexible foam material such as foamable urethane is used, but other flexible members such as an aggregate of fiber nonwoven fabrics can be used.
＜第３の実施形態＞
　図１０～１２は、本発明の第３の実施形態を示したものである。図１０は離隔シート３０の平面図であって、その一部を破断させたもの、図１１は図１０のＸＩ－ＸＩ線断面図、図１２は離隔シート弾性体３８が収縮したときの説明図である。この実施形態では、可変形手段としての離隔シート弾性体３８と、第１および第２シート３０ａ，３０ｂ間に位置する第１接合部８２とを含むことを特徴とするものであり、他の構成要素は第１の実施形態と同様である。第１の実施形態と同様の構成要素については、第１の実施形態と同じ符号を用い、その詳細な説明を省略する。 <Third Embodiment>
10 to 12 show a third embodiment of the present invention. 10 is a plan view of the separation sheet 30 with a part thereof broken, FIG. 11 is a sectional view taken along line XI-XI in FIG. 10, and FIG. 12 is an explanatory view when the separation sheet elastic body 38 contracts. It is. This embodiment is characterized by including a separation sheet elastic body 38 as a deformable means, and a first joint portion 82 located between the first and second sheets 30a and 30b, and other configurations. The elements are the same as in the first embodiment. Constituent elements similar to those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and detailed description thereof is omitted.
　離隔シート弾性体３８は、離隔シート３０の第１シート３０ａおよび第２シート３０ｂの間に伸長状態で収縮可能に取り付けられている。離隔シート弾性体３８は、中間部分３４の近傍においては、仮想縦中心線Ｐ－Ｐに向かって離間距離を縮めるように湾曲している。このように湾曲した部分において、第１および第２シート３０ａ，３０ｂおよび離隔シート弾性体３８を互いに接合する第１接合部８２を形成している。第１接合部８２は、ホットメルト接着剤等の接着手段によって構成されている。 The separation sheet elastic body 38 is attached between the first sheet 30a and the second sheet 30b of the separation sheet 30 so as to be contractable in an extended state. The separation sheet elastic body 38 is curved in the vicinity of the intermediate portion 34 so as to reduce the separation distance toward the virtual longitudinal center line PP. In such a curved portion, a first joining portion 82 that joins the first and second sheets 30a and 30b and the separation sheet elastic body 38 to each other is formed. The 1st junction part 82 is comprised by adhesion means, such as a hot-melt-adhesive agent.
　第１接合部８２は、縦方向Ｙに離間して複数形成されるとともに、離隔シート弾性体３８を横方向Ｘに横切って延びている。したがって、第１接合部８２によって、第１および第２シート３０ａ，３０ｂと、離隔シート弾性体３８とが互いに接合される。第１および第２シート３０ａ，３０ｂは、少なくとも中間部分３４近傍では、第１接合部８２以外の接合手段で接合されることはなく、互いに離間可能とされている。 A plurality of first joining portions 82 are formed apart in the longitudinal direction Y and extend across the separation sheet elastic body 38 in the transverse direction X. Therefore, the first and second sheets 30a and 30b and the separation sheet elastic body 38 are joined to each other by the first joining portion 82. The first and second sheets 30a and 30b are not joined by a joining means other than the first joining portion 82 at least in the vicinity of the intermediate portion 34, and can be separated from each other.
　図１１は、離隔シート弾性体３８を収縮させない状態を示したものであり、図１２は、離隔シート弾性体３８が収縮した状態を示したものである。離隔シート弾性体３８が収縮すると、第１接合部８２以外の部分において、第１および第２シート３０ａ，３０ｂが撓んで、それらの対向面とは反対側に突出するように皺を形成する。皺が形成されることによって、離隔シート３０の中間部分３４においては、厚さ方向の嵩高が大きくなり、その分、着用者との隙間を減少させることができる。また、第１および第２シート３０ａ，３０ｂを繊維不織布等の柔軟なシートで形成することによって、皺は着用者の体のラインに沿って密着することが可能であり、かつ、着用者の肌に対する刺激を抑えることができる。また、皺は、横方向Ｘに複数延びるので、排泄物の縦方向Ｙへの流動を規制することができ、尿便分離の機能を発揮することができる。 FIG. 11 shows a state in which the separation sheet elastic body 38 is not contracted, and FIG. 12 shows a state in which the separation sheet elastic body 38 is contracted. When the separation sheet elastic body 38 contracts, the first and second sheets 30a and 30b are bent at portions other than the first joint portion 82, and a ridge is formed so as to protrude on the opposite side to the facing surface. By forming the ridges, the intermediate portion 34 of the separation sheet 30 becomes bulky in the thickness direction, and the gap with the wearer can be reduced accordingly. Further, by forming the first and second sheets 30a and 30b with a flexible sheet such as a fiber nonwoven fabric, the heel can be adhered along the line of the wearer's body and the wearer's skin Can suppress irritation. Moreover, since a plurality of sputums extend in the lateral direction X, the flow of excrement in the vertical direction Y can be restricted, and the function of separating urine and feces can be exhibited.
　離隔シート弾性体３８が湾曲する中央部分３４において、これを第１および第２シート３０ａ，３０ｂに対して接合する第１接合部８２を形成することによって、離隔シート弾性体３８を確実に固定することができ、この弾性体の抜けや位置ずれを防止することができる。
　第１接合部８２は、第１および第２シート３０ａ，３０ｂを少なくとも中間部分３４において縦方向Ｙに間欠的に接合するものであればよいので、離隔シート弾性体３８に重なって形成される必要はない。ただし、離隔シート弾性体３８の抜けや位置ずれを防止するためには、これに重なって形成されることが好ましい。位置ずれの防止が達成できるものとして、例えば、第１接合部８２が、離隔シート弾性体３８の横方向Ｘ近傍に形成されるものであればよい。この実施形態では、中間部分３４において離隔シート弾性体３８が伸長状態で仮想縦中心線Ｐ－Ｐへと湾曲されているので、少なくとも、離隔シート弾性体３８の横方向Ｘ外側に第１接合部８２が形成されることによって、位置ずれを防止することができる。 In the central portion 34 where the separation sheet elastic body 38 is curved, a first joining portion 82 is formed to join the separation sheet elastic body 38 to the first and second sheets 30a and 30b, thereby securely fixing the separation sheet elastic body 38. It is possible to prevent the elastic body from coming off or being displaced.
Since the 1st junction part 82 should just join the 1st and 2nd sheet | seat 30a, 30b intermittently in the vertical direction Y at least in the intermediate part 34, it needs to overlap with the separation sheet | seat elastic body 38, and needs to be formed. There is no. However, in order to prevent the separation sheet elastic body 38 from being detached or displaced, it is preferable that the separation sheet elastic body 38 is formed so as to overlap therewith. For example, the first joining portion 82 may be formed in the vicinity of the lateral direction X of the separation sheet elastic body 38 as the one capable of preventing the displacement. In this embodiment, since the separation sheet elastic body 38 is curved in the extended state to the virtual longitudinal center line PP in the intermediate portion 34, the first joint portion is at least on the outer side in the lateral direction X of the separation sheet elastic body 38. By forming 82, position shift can be prevented.

FIG. 13 shows a fourth embodiment of the present invention. FIG. 13 is a plan view of the separation sheet 30, a part of which is broken. In this embodiment, the separation sheet elastic body 38 and the first joint portion 83 located between the first and second sheets 30a and 30b are included as deformation means, and the other components are as follows. This is the same as in the first embodiment. Constituent elements similar to those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and detailed description thereof is omitted.
　第１接合部８３は、離隔シート３０の中央部分３４近傍に形成されるものであって、例えば加熱加圧処理によって第１および第２シート３０ａ，３０ｂを互いに溶着させることによって形成されるものである。このような第１接合部８３は、離隔シート弾性体３８の横方向Ｘ両側に位置するものを一対として形成されるものであって、これら対が縦方向Ｙに離間して複数形成されている。 The 1st junction part 83 is formed in the center part 34 vicinity of the separation sheet 30, Comprising: For example, it forms by welding the 1st and 2nd sheet | seat 30a, 30b mutually by a heat pressurization process. is there. Such first joint portions 83 are formed as a pair of ones located on both sides in the lateral direction X of the separation sheet elastic body 38, and a plurality of these pairs are formed apart in the longitudinal direction Y. .
　上記のように第１接合部８３を形成することによって、図１２に示したのと同様に、離隔シート弾性体３８の収縮によって、第１および第２シート３０ａ，３０ｂに皺が形成される。皺が形成されることによって、着用時における着用者と隙間を解消することができる。
　また、第１接合部８３を点状に形成することができるので、第１接合部８３の形成によって第１および第２シート３０ａ，３０ｂの剛性が大きくなった場合であっても、肌への刺激を抑制することができる。第１接合部８３を離隔シート弾性体３８の横方向Ｘ両側に形成することとしたので、離隔シート弾性体３８の横方向Ｘにおける位置ずれを防止することができる。 By forming the first joint portion 83 as described above, wrinkles are formed in the first and second sheets 30a and 30b due to the contraction of the separation sheet elastic body 38, as shown in FIG. By forming the heel, the gap between the wearer and the wearer can be eliminated.
Moreover, since the 1st junction part 83 can be formed in dot shape, even if it is a case where the rigidity of 1st and 2nd sheet | seat 30a, 30b becomes large by formation of the 1st junction part 83, it is to a skin. Stimulation can be suppressed. Since the 1st junction part 83 was formed in the horizontal direction X both sides of the separation sheet elastic body 38, the position shift in the horizontal direction X of the separation sheet elastic body 38 can be prevented.
　この実施形態において、第１接合部８３を離隔シート弾性体３８の横方向Ｘ両側に形成することとしているが、少なくともその外側にあればよい。また、離隔シート弾性体３８を介して横方向Ｘに並ぶ２つの第１接合部８３を一組の対として説明しているが、必ずしも対をなしている必要はなく、２つの接合部が縦方向Ｙにずれているような場合であってもよい。 In this embodiment, the first joint 83 is formed on both sides in the lateral direction X of the separation sheet elastic body 38, but it may be at least on the outer side. Further, the two first joint portions 83 arranged in the lateral direction X via the separation sheet elastic body 38 are described as a pair, but the pair does not necessarily have to be paired and the two joint portions are vertically The case where it has shifted | deviated to the direction Y may be sufficient.
＜第５の実施形態＞
　図１４および１５は、本発明の第５の実施形態を示したものである。図１４は離隔シート３０の部分破断平面図、図１５は離隔シート弾性体３８の収縮時における図１４のＸＶ－ＸＶ線断面図である。この実施形態では、可変形手段としての可変形シート９０と、離隔シート３０および可変形シート９０間に位置する第２接合部８４と、離隔シート弾性体３８とを含むことを特徴とするものであり、他の構成要素は第１の実施形態と同様である。第１の実施形態と同様の構成要素については、第１の実施形態と同じ符号を用い、その詳細な説明を省略する。 <Fifth Embodiment>
14 and 15 show a fifth embodiment of the present invention. 14 is a partially broken plan view of the separation sheet 30, and FIG. 15 is a cross-sectional view taken along the line XV-XV in FIG. 14 when the separation sheet elastic body 38 is contracted. This embodiment includes a deformable sheet 90 as a deformable means, a second joint 84 positioned between the separation sheet 30 and the deformable sheet 90, and a separation sheet elastic body 38. The other components are the same as those in the first embodiment. Constituent elements similar to those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and detailed description thereof is omitted.
　離隔シート３０の第１シート３０ａの身体側には、一対の可変形シート９０を第２接合部８４を介して接合している。可変形シート９０は、透液性の繊維不織布等を用いることができ、中間部分３４の近傍であって、離隔シート弾性体３８と重なる位置において形成されている。第２接合部８４は、例えば、ホットメルト接着剤等の接着手段によって形成されている。第２接合部８４は、可変形シート９０の全域であって、横方向Ｘに延びるとともに、縦方向Ｙに離間して形成されている。 A pair of deformable sheets 90 are joined to the body side of the first sheet 30 a of the separation sheet 30 via the second joining portion 84. The deformable sheet 90 can be made of a liquid permeable non-woven fabric or the like, and is formed in the vicinity of the intermediate portion 34 and at a position overlapping with the separation sheet elastic body 38. The 2nd junction part 84 is formed of adhesion | attachment means, such as a hot-melt-adhesive agent, for example. The second joint portion 84 is the entire region of the deformable sheet 90 and extends in the horizontal direction X and is spaced apart in the vertical direction Y.
　上記のような構成において、離隔シート弾性体３８が収縮すると、可変形シート９０が撓んで、第２接合部８４の間では、身体側に向かって突出するように皺が形成される。皺が形成されることによって、着用時における着用者との隙間を解消することができる。
　第１および第２シート３０ａ，３０ｂとは別部材の可変形シート９０を備えることとしているので、第１および第２シート３０ａ，３０ｂはそれらの全域で互いに接合されるようにすることができ、これら両シートを強固に接合することができる。また、強固な接合によって第１および第２シート３０ａ，３０ｂの間に取り付けた離隔シート弾性体３８の抜けや位置ずれを防止することもできる。 In the above-described configuration, when the separation sheet elastic body 38 contracts, the deformable sheet 90 bends, and a ridge is formed between the second joint portions 84 so as to protrude toward the body side. By forming the heel, the gap with the wearer at the time of wearing can be eliminated.
