The leg elastic member 58 is attached in an extended state between the barrier sheets 30 and 31 and the back sheet 21 so as to be shrinkable via a hot melt adhesive (not shown). In the illustrated diaper 10, in the lateral direction X, the separation dimension Lc between the leg elastic member 58 and the side edge of the absorbent core 22 is about 25 mm. The leg elastic member 58 is preferably in the range of about 450 to 940 dtex, and the leg elastic member 58 in the illustrated example is about 470 dtex.
The distal edge 57 is provided with two strand-like or string-like barrier elastic members 59 extending in the longitudinal direction Y so as to be contracted. The barrier elastic member 59 is attached between the folded barrier sheets 30 and 31 in a stretched state so as to be shrinkable via a hot melt adhesive (not shown). At the distal edge 57, when the diaper 10 is worn, the barrier sheets 30, 31 are separated from the skin facing surface of the top sheet 20 by the contraction force of the barrier elastic member 59, and body fluid such as urine leaks in the lateral direction X. A pair of barrier cuffs 65 are formed to prevent this (see FIG. 3).
　吸収性コア２２は、フラップパルプと超吸水性ポリマー粒子との混合等から形成され、トップシート２０とバックシート２１との間に介在させてある。吸収性コア２２の横方向Ｙの寸法は、例えば約１００ｍｍである。なお、吸収性コア２２は、不図示のティッシュペーパー等の拡散シートによって被包してもよい。
　吸収性コア２２は、クロッチ域１４から前後ウエスト域１２、１３に縦方向Ｙに延び、主として尿等の体液を吸収する本体部２２ａと、前ウエスト域１２にのみ設けたコア前端部２２ｂとを備えている。また、この吸収性コア２２は、本体部２２ａとコア前端部２２ｂとの間において横方向Ｙに延びる折曲案内部２４とを備えている。 The absorbent core 22 is formed from a mixture of flap pulp and superabsorbent polymer particles or the like, and is interposed between the top sheet 20 and the back sheet 21. The dimension in the transverse direction Y of the absorbent core 22 is, for example, about 100 mm. The absorbent core 22 may be encapsulated by a diffusion sheet such as tissue paper (not shown).
The absorbent core 22 extends in the longitudinal direction Y from the crotch region 14 to the front and rear waist regions 12 and 13, and includes a main body portion 22a that mainly absorbs body fluids such as urine, and a core front end portion 22b provided only in the front waist region 12. I have. Moreover, this absorptive core 22 is provided with the bending guide part 24 extended in the horizontal direction Y between the main-body part 22a and the core front-end part 22b.
　折曲案内部２４は、シャーシ１１を展開した状態（図２参照）において、肌対向面から非肌対向面までの厚さを、本体部２２ａおよびコア前端部２２ｂに比して薄くすることによって形成された凹状の溝である。換言すれば、この折曲案内部２４は、本体部２２ａとコア前端部２２ｂとの間を縦方向Ｙに連結し、肌対向面から非肌対向面に向かう厚さ方向の寸法を、本体部２２ａよりも薄くすることによって形成した吸収性コア２２の一部である。図１～８に示す折曲案内部２４は、肌対向面側に溝が形成され、肌対向面が凹んでいる。
　折曲案内部２４は、例えば、吸収性コア２２の一部を取り除くことによって形成してある。吸収性コア２２の一部を取り除くことによって折曲案内部２４を形成した場合、当該部位の剛性が本体部２２ａおよびコア前端部２２ｂの剛性に比して低下するため、折り曲げが容易となる。
　本体部２２ａおよびコア前端部２２ｂの両対向縁部２４ａ、２４ｂは、横方向Ｘにおいて、縦軸Ｐの近傍が互いに最も近接する一方、縦軸Ｐから横方向Ｙに離間するに従って徐々に相互の距離が大きくなる曲状に形成してあるため、対向縁部２４ａ、２４ｂがトップシート２０を介して着用者の肌に当接しても、肌に与える刺激を減少することができる。
　図１～８に示す例では、図２に示す前ウエスト域１２の縦方向の寸法Ｌｄが約７０．０～９０．０ｍｍの場合において、折曲案内部２４の縦軸Ｐにおける両対向縁部２４ａ、２４ｂの離間寸法Ｌａ（図４参照）は、好ましくは約２．０～１０．０ｍｍ、より好ましくは約５．０～１０．０ｍｍである。また、折曲案内部２４の横方向Ｙの両側縁における両対向縁部２４ａ、２４ｂの離間寸法Ｌｂ（図４参照）は、例えば約１０ｍｍ以上であることが好ましく、より好ましくは約２５ｍｍ以上であることが好ましい。さらに、この例において、コア前端部２２ｂの縦方向Ｙの寸法Ｌｅ（図４参照）は、好ましくは約２０．０～５０．０ｍｍである。 In the state where the chassis 11 is unfolded (see FIG. 2), the bending guide portion 24 is formed by making the thickness from the skin facing surface to the non-skin facing surface thinner than the main body portion 22a and the core front end portion 22b. It is a concave groove formed. In other words, the bending guide portion 24 connects the body portion 22a and the core front end portion 22b in the longitudinal direction Y, and determines the dimension in the thickness direction from the skin facing surface to the non-skin facing surface. It is a part of the absorptive core 22 formed by making it thinner than 22a. 1 to 8, grooves are formed on the skin facing surface side, and the skin facing surface is recessed.
The bending guide part 24 is formed, for example, by removing a part of the absorbent core 22. When the bending guide part 24 is formed by removing a part of the absorbent core 22, the rigidity of the part is lower than the rigidity of the main body part 22a and the core front end part 22b, so that the bending becomes easy.
The opposite edge portions 24a and 24b of the main body portion 22a and the core front end portion 22b are close to each other in the vicinity of the vertical axis P in the horizontal direction X, and gradually move away from each other as the distance from the vertical axis P to the horizontal direction Y increases. Since it forms in the curved shape where distance becomes large, even if the opposing edge parts 24a and 24b contact | abut to a wearer's skin via the top sheet 20, the irritation | stimulation given to skin can be reduced.
In the example shown in FIGS. 1 to 8, when the longitudinal dimension Ld of the front waist region 12 shown in FIG. 2 is about 70.0 to 90.0 mm, both opposing edge portions on the longitudinal axis P of the bending guide portion 24 The separation dimension La (see FIG. 4) of 24a and 24b is preferably about 2.0 to 10.0 mm, more preferably about 5.0 to 10.0 mm. Further, a separation dimension Lb (see FIG. 4) of the opposing edge portions 24a and 24b at both side edges in the lateral direction Y of the bending guide portion 24 is preferably about 10 mm or more, and more preferably about 25 mm or more. Preferably there is. Further, in this example, the dimension Le (see FIG. 4) in the longitudinal direction Y of the core front end portion 22b is preferably about 20.0 to 50.0 mm.
　折曲案内部２４は、肌対向面から非肌対向面における厚さ方向において、シャーシ１１の非肌対向面に位置する第２ファスニング要素１８の下側縁１８ａと重なる位置に形成してある（図２参照）。
　また、前ウエスト域１２の非肌対向面には、おむつ１０の非肌対向面側から折曲案内部２４の位置を確認することができる折曲案内表示部２８を形成してある（図１参照）。折曲案内表示部２８は、上記厚さ方向において、非肌対向面において、折曲案内部２４に対応するよう配置してある。折曲案内表示部２８は、着用者および着用補助者が折曲案内部２４の位置を容易に視認することができるように、第２ファスニング要素１８とは異なる色彩をバックシート２１に付すことによって形成してもよいし、テープ片を貼り付けることによって形成してもよい。 The bending guide portion 24 is formed at a position overlapping the lower edge 18a of the second fastening element 18 located on the non-skin facing surface of the chassis 11 in the thickness direction from the skin facing surface to the non-skin facing surface ( (See FIG. 2).
Moreover, the bending guidance display part 28 which can confirm the position of the bending guide part 24 from the non-skin opposing surface side of the diaper 10 is formed in the non-skin opposing surface of the front waist area 12 (FIG. 1). reference). The bending guide display unit 28 is arranged to correspond to the bending guide unit 24 on the non-skin facing surface in the thickness direction. The bending guide display unit 28 attaches a color different from that of the second fastening element 18 to the backsheet 21 so that the wearer and the wearer can easily see the position of the bending guide unit 24. You may form, and you may form by sticking a tape piece.
　図２、４に示すように、前ウエスト域１２には、折曲案内弾性部材（弾性部材）６０を設けてある。折曲案内弾性部材６０は、縦軸Ｐの横方向Ｘの両側において、縦軸Ｐに平行で縦方向Ｙに延びる態様であって、溝である折曲案内部２４にのみ設けてある。より詳細には、溝である折曲案内部２４の横方向Ｘの側縁に沿って設けてある。図示する折曲案内弾性部材６０は、上記厚さ方向における防漏シート２９とバックシート２１との間において、ホットメルト接着剤（図示せず）を介して収縮可能なように伸長状態で取り付けてある（図８参照）。換言すれば、折曲案内弾性部材６０は、上記厚さ方向において、吸収性コア２２よりも非肌対向面側に設けてある。図示する折曲案内弾性部材６０は、約６２０ｄｔｅｘのストリング状のものを２本用いてあり、約１．８倍に伸長させることによって、収縮力が作用するようにシート２１、２９の少なくとも一方に取り付けてある。 As shown in FIGS. 2 and 4, the front waist region 12 is provided with a bending guide elastic member (elastic member) 60. The bending guide elastic member 60 is an aspect that extends in the vertical direction Y in parallel to the vertical axis P on both sides of the horizontal direction X of the vertical axis P, and is provided only in the bending guide portion 24 that is a groove. More specifically, it is provided along the side edge in the lateral direction X of the bending guide portion 24 that is a groove. The illustrated bending guide elastic member 60 is attached in a stretched state so as to be shrinkable via a hot melt adhesive (not shown) between the leak-proof sheet 29 and the back sheet 21 in the thickness direction. Yes (see FIG. 8). In other words, the bending guide elastic member 60 is provided on the non-skin facing surface side with respect to the absorbent core 22 in the thickness direction. The bending guide elastic member 60 shown in the figure uses two string-shaped members of about 620 dtex, and is stretched about 1.8 times to at least one of the sheets 21 and 29 so that the contraction force acts. It is attached.
　図５は、おむつ１０の第２使用態様を示す図であり、図６は、図５のＶＩ－ＶＩ線断面図である。 FIG. 5 is a diagram showing a second usage mode of the diaper 10, and FIG. 6 is a sectional view taken along line VI-VI in FIG.
　図５に示すように、このおむつ１０は、前ウエスト域１２を折曲案内部２４に沿って非肌対向面側に向かって折り曲げてから、第３ファスニング要素４５に第１ファスニング要素１７を係止し、第２ファスニングシステムを使用することによって、前ウエスト域１２をクロッチ域１４の非肌対向面に折り重ねた状態でも着用することができる。この場合には、着用者の腹部が露出するため、着用者が未熟児を含む新生児の場合、前ウエスト域１２による締め付けによってその複式呼吸が妨げられることはない。特に、新生児の場合には、へそおよびその周辺が十分に成熟しておらず、前ウエスト域１２によるわずかな締め付けによっても刺激を与えるおそれがあるが、このおむつ１０では、かかる事態を避けることができる。
　加えて、へその下方において、第１ファスニング要素１７が第３ファスニング要素４５に係合されているため、たとえ前ウエスト域１２が着用者の腹部に当接していなくても、下腹部において安定的におむつ１０を着用者の身体に固定させることができるとともに、着用中に前ウエスト域１２の折曲状態が解かれることはない。 As shown in FIG. 5, the diaper 10 folds the front waist region 12 along the bending guide portion 24 toward the non-skin facing surface side, and then engages the first fastening element 17 with the third fastening element 45. By stopping and using the second fastening system, the front waist region 12 can be worn even when folded over the non-skin facing surface of the crotch region 14. In this case, since the wearer's abdomen is exposed, when the wearer is a newborn baby including a premature baby, the double breathing is not hindered by tightening by the front waist region 12. In particular, in the case of a newborn baby, the navel and its surroundings are not sufficiently matured, and there is a risk of irritation even by slight tightening by the front waist region 12, but in this diaper 10, such a situation can be avoided. it can.
In addition, since the first fastening element 17 is engaged with the third fastening element 45 below the navel, even if the front waist region 12 is not in contact with the wearer's abdomen, the lower abdomen is stable. The diaper 10 can be fixed to the wearer's body, and the bent state of the front waist region 12 is not unraveled during wearing.
　図７は、おむつ１０を不図示のパッケージに入れるために折りたたまれていた状態から解放された後における断面図であり、図８は、折曲案内弾性部材６０の作用を説明する図である。
　かかるおむつ１０では、折曲案内弾性部材６０の収縮力によって、パッケージからおむつ１０を取り出せば、図７、８に示すように、本体部２２ａに対してコア前端部２２ｂを非肌対向面側に起立させることができる。よって、着用する前に折曲案内部２４が視認できるように前ウエスト域１２が折れ曲がる。換言すれば、着用する前に折曲案内部２４において簡易的に折り目を付けることができるため、折曲案内部２４に沿って前ウエスト域１２を確実に折り曲げることができる。しかも、折曲案内部２４を設ける位置は、第２ファスニング要素１８の位置に合わせる必要がない。
　また、折曲案内部２４は、本体部２２ａとコア前端部２２ｂとの間を縦方向Ｙに連結し、肌対向面から非肌対向面に向かう厚さ方向の寸法が、吸収性コア２２の一部を本体部２２ａよりも薄くすることによって形成してあるため、本体部２２ａおよびコア前端部２２ｂのいずれか一方の部位の位置を決定すれば、別の一方の部位の位置も決まるため、位置決めが煩雑になることを防止することができる。
　さらに、折曲案内弾性部材６０は、上記厚さ方向において、吸収性コア２２よりも非肌対向面側に設けてあるため、前ウエスト域１２を非肌対向面側に向けて折り曲げる場合、吸収性コア２２が邪魔になることを抑えることができる。 FIG. 7 is a cross-sectional view after the diaper 10 is released from the folded state so as to be put in a package (not shown), and FIG. 8 is a view for explaining the operation of the bending guide elastic member 60.
In the diaper 10, when the diaper 10 is taken out of the package by the contraction force of the bending guide elastic member 60, the core front end 22 b is placed on the non-skin facing surface side with respect to the main body 22 a as shown in FIGS. Can stand. Therefore, the front waist region 12 bends so that the bending guide part 24 can be visually recognized before wearing. In other words, the fold guide portion 24 can be easily creased before being worn, so that the front waist region 12 can be reliably bent along the fold guide portion 24. In addition, the position where the bending guide portion 24 is provided need not match the position of the second fastening element 18.
Moreover, the bending guide part 24 connects between the main body part 22a and the core front end part 22b in the vertical direction Y, and the dimension in the thickness direction from the skin facing surface to the non-skin facing surface is Since a part is formed by making it thinner than the main body 22a, if the position of either one of the main body 22a and the core front end 22b is determined, the position of the other one is also determined. It is possible to prevent the positioning from becoming complicated.
Furthermore, since the bending guide elastic member 60 is provided on the non-skin facing surface side with respect to the absorbent core 22 in the thickness direction, it is absorbed when the front waist region 12 is folded toward the non-skin facing surface side. It can suppress that the sex core 22 gets in the way.

　この第１変形例のおむつ１０Ａにおいて、上述したおむつ１０と同一の構成を有するものには同一の符号を付して説明を省略する。 FIG. 9 is a perspective view of a diaper 10A of a first modified example of the first embodiment, and FIG. 10 is a partially broken plan view of the diaper 10A viewed from the skin-facing surface in a developed state. 11 is a cross-sectional view taken along the line XI-XI of FIG. 9, FIG. 12 is a view showing a second usage mode of the diaper 10A, and FIG. 13 is a cross-sectional view taken along the line XIII-XIII of FIG.
In the diaper 10A of the first modified example, the same reference numerals are given to those having the same configuration as the diaper 10 described above, and the description thereof is omitted.
　このおむつ１０Ａは、第１ファスニング要素１７にそれぞれ係合する第２ファスニング要素１８Ａと、第３ファスニング要素４５Ａとを前ウエスト域１２の非肌対向面に設けてある。第３ファスニング要素４５Ａは、第２ファスニング要素１８Ａの下方に配置してある。
　第２ファスニング要素１８Ａおよび第３ファスニング要素４５Ａは、前ウエスト域１２の非肌対向面において横方向Ｘへ延びる略細長矩形状の繊維不織布シートであって、その表面上には、上記ライン４３、４４と同様のライン４３Ａ、４４Ａをそれぞれ形成してある。これらのライン４３Ａ、４４Ａも例えばエンボス加工を行なうことによって構成してある。なお、第３ファスニング要素４５Ａは、ライン４３Ａ、４４Ａを設けるものに限られず、通常のトップシート２０、例えばスパンボンド繊維不織布から形成したトップシート２０でもよい。 In the diaper 10 </ b> A, a second fastening element 18 </ b> A and a third fastening element 45 </ b> A that are respectively engaged with the first fastening element 17 are provided on the non-skin facing surface of the front waist region 12. The third fastening element 45A is disposed below the second fastening element 18A.
The second fastening element 18A and the third fastening element 45A are substantially elongated rectangular fiber nonwoven fabric sheets extending in the lateral direction X on the non-skin facing surface of the front waist region 12, and on the surface thereof, the line 43, Lines 43A and 44A similar to 44 are formed. These lines 43A and 44A are also configured by, for example, embossing. In addition, the 3rd fastening element 45A is not restricted to what provides the lines 43A and 44A, The top sheet 20 formed from the normal top sheet 20, for example, a spun bond fiber nonwoven fabric, may be sufficient.
　折曲案内部２４Ａは、第２ファスニング要素１８Ａと、第３ファスニング要素４５Ａとの間に形成してある。この折曲案内部２４Ａは、シャーシ１１を展開した状態（図１０参照）において、肌対向面から非肌対向面までの厚さ方向の寸法を、本体部２２ａおよびコア前端部２２ｂに比して薄くすることによって形成された凹状の溝である。図９～１３に示す折曲案内部２４Ａは、非肌対向面側に溝が形成され、非肌対向面が凹んでいる（図１１参照）。 The bending guide portion 24A is formed between the second fastening element 18A and the third fastening element 45A. In the state where the chassis 11 is unfolded (see FIG. 10), the bending guide portion 24A has a dimension in the thickness direction from the skin facing surface to the non-skin facing surface compared to the main body portion 22a and the core front end portion 22b. It is a concave groove formed by thinning. In the bending guide portion 24A shown in FIGS. 9 to 13, a groove is formed on the non-skin facing surface side, and the non-skin facing surface is recessed (see FIG. 11).
　折曲案内表示部２８Ａは、シャーシ１１における非肌対向面において、第２ファスニング要素１８Ａと第３ファスニング要素４５Ａとの間に形成してある。 The bending guide display portion 28A is formed on the non-skin facing surface of the chassis 11 between the second fastening element 18A and the third fastening element 45A.
　折曲案内弾性部材６０Ａは、縦軸Ｐの横方向Ｘの両側において、縦方向Ｙに延びる態様であって、溝である折曲案内部２４Ａにのみ設けてある。図示する折曲案内弾性部材６０Ａは、上記厚さ方向における吸収性コア２２とトップシート２０との間において、ホットメルト接着剤（図示せず）を介して伸縮可能なように伸長状態で取り付けてある（図１５参照）。換言すれば、折曲案内弾性部材６０Ａは、厚さ方向において吸収性コア２２よりも肌対向面側に設けてある点が、上記弾性部材６０と異なり、他の点は同じである。 The bending guide elastic member 60A extends in the vertical direction Y on both sides in the horizontal direction X of the vertical axis P, and is provided only in the bending guide portion 24A that is a groove. The illustrated bending guide elastic member 60A is attached in an extended state so as to be expandable and contractible via a hot melt adhesive (not shown) between the absorbent core 22 and the top sheet 20 in the thickness direction. Yes (see FIG. 15). In other words, the bending guide elastic member 60 </ b> A is different from the elastic member 60 in that the bending guide elastic member 60 </ b> A is provided closer to the skin facing surface than the absorbent core 22 in the thickness direction.
　図１４は、おむつ１０Ａを不図示のパッケージに入れるために折りたたまれていた状態から解放された後における断面図であり、図１５は、折曲案内弾性部材６０Ａの作用を説明する図である。
　かかるおむつ１０Ａでは、折曲案内弾性部材６０Ａの収縮力によって、パッケージからおむつ１０Ａを取り出せば、図１４、１５に示すように、折曲案内弾性部材６０Ａの収縮力によって、本体部２２ａに対してコア前端部２２ｂを肌対向面側に起立させることができる。よって、着用する前に折曲案内部２４Ａが視認できるように前ウエスト域１２が折れ曲がる。換言すれば、着用する前に折曲案内部２４Ａにおいて簡易的に折り目を付けることができるため、折曲案内部２４Ａに沿って前ウエスト域１２を確実に折り曲げることができる。
　また、折曲案内弾性部材６０Ａは、上記厚さ方向において、吸収性コア２２よりも肌対向面側に設けてあるため、前ウエスト域１２を肌対向面側に向けて折り曲げる場合、吸収性コア２２が邪魔になることを抑えることができる。 FIG. 14 is a cross-sectional view after the diaper 10A is released from the folded state so as to be put in a package (not shown), and FIG. 15 is a view for explaining the operation of the bending guide elastic member 60A.
In the diaper 10A, when the diaper 10A is taken out of the package by the contraction force of the bending guide elastic member 60A, as shown in FIGS. 14 and 15, the contraction force of the bending guide elastic member 60A causes the main body portion 22a. The core front end 22b can be erected on the skin facing surface side. Therefore, the front waist region 12 is bent so that the bending guide portion 24A can be visually recognized before wearing. In other words, the fold guide portion 24A can be easily creased before being worn, so that the front waist region 12 can be reliably bent along the fold guide portion 24A.
Further, since the bending guide elastic member 60A is provided on the skin facing surface side with respect to the absorbent core 22 in the thickness direction, when the front waist region 12 is bent toward the skin facing surface side, the absorbent core It can suppress that 22 gets in the way.
　図１６は、第１実施形態の第２変形例のおむつ１０Ｂを展開した状態において、その要部を肌対向面から見た一部破断展開平面図である。
　この第２変形例のおむつ１０Ｂにおいて、上述したおむつ１０と同一の構成を有するものには同一の符号を付して説明を省略する。 FIG. 16 is a partially broken plan view of the essential part seen from the skin facing surface in a state where the diaper 10B of the second modified example of the first embodiment is developed.
In the diaper 10B of the second modified example, the same reference numerals are given to those having the same configuration as the diaper 10 described above, and description thereof is omitted.
　このおむつ１０Ｂの折曲案内弾性部材６０Ｂは、折曲案内部２４のみならず、本体部２２ａの対向縁部２４ｂおよびコア前端部２２ｂの対向縁部２４ａを超えるように縦方向Ｙに延びている。
　この折曲案内弾性部材６０Ｂの上端部６１ａは、ホットメルト接着剤（不図示）を直接塗布することによって、防漏シート２９またはバックシート２１の少なくとも一方に取り付けてある。
　折曲案内弾性部材６０Ｂの下端部６１ｂは、ホットメルト接着剤（不図示）を直接塗布することによって、防漏シート２９またはバックシート２１の少なくとも一方に取り付けてある。
　縦方向Ｙにおける上端部６１ａと下端部６１ｂとの間の中間部（両端部６１ａ、６１の間）６１ｃは、ホットメルト接着剤を塗布することはなく、防漏シート２９、バックシート２１のいずれに対しても接着していない。
　図示例の折曲案内弾性部材６０Ｂは、縦軸Ｐの両側に２本ずつ設けてあり、縦方向Ｙの長さが約４５ｍｍであり、上端部６１ａの縦方向Ｙの長さが約１５ｍｍであり、下端部６１ｂの縦方向Ｙの長さが約１５ｍｍであり、中間部６１ｃの縦方向Ｙの長さが約２５ｍｍである。また、折曲案内弾性部材６０Ｂは、約６２０ｄｔｅｘのストリング状のものを縦軸Ｐの両側に２本ずつ設けてあり、約２．１倍に伸長させることによって、単位長さ当たり約０．０４ｇ／ｍのホットメルト接着剤６２を直接塗布することによって、収縮力が作用するように例えば、上下端部６１ａ、６１ｂにおいてバックシート２１に取り付けてある。縦軸Ｐの一方の側において、折曲案内弾性部材６０Ｂの離間寸法は、例えば約３ｍｍである。 The bending guide elastic member 60B of the diaper 10B extends in the longitudinal direction Y so as to exceed not only the bending guide part 24 but also the opposing edge part 24b of the main body part 22a and the opposing edge part 24a of the core front end part 22b. .
The upper end portion 61a of the bending guide elastic member 60B is attached to at least one of the leak-proof sheet 29 or the back sheet 21 by directly applying a hot melt adhesive (not shown).
The lower end portion 61b of the bending guide elastic member 60B is attached to at least one of the leak-proof sheet 29 or the back sheet 21 by directly applying a hot melt adhesive (not shown).
An intermediate portion (between both end portions 61a and 61) 61c between the upper end portion 61a and the lower end portion 61b in the longitudinal direction Y is not coated with a hot melt adhesive, and any one of the leakproof sheet 29 and the back sheet 21 is used. It does not adhere to the
Two bending guide elastic members 60B in the illustrated example are provided on both sides of the vertical axis P, the length in the vertical direction Y is about 45 mm, and the length in the vertical direction Y of the upper end portion 61a is about 15 mm. Yes, the length in the vertical direction Y of the lower end portion 61b is about 15 mm, and the length in the vertical direction Y of the intermediate portion 61c is about 25 mm. Further, the bending guide elastic member 60B is provided with two string-like members of about 620 dtex on both sides of the vertical axis P, and is about 0.04 g per unit length by extending about 2.1 times. For example, the upper and lower end portions 61a and 61b are attached to the back sheet 21 so that the contraction force acts by directly applying the / m hot melt adhesive 62. On one side of the vertical axis P, the separation distance of the bending guide elastic member 60B is, for example, about 3 mm.
　図１７は、図１６のＸＶＩＩ－ＸＶＩＩ線断面図である。図示するように、トップシート２０と吸収性コア２２との間には、これらを接着するためのホットメルト接着剤７０を設けてある。吸収性コア２２と防漏シート２９との間には、これらを接着するためのホットメルト接着剤７１を設けてある。防漏シート２９とバックシート２１の間には、これらを接着するためのホットメルト接着剤７２を設けてある。 FIG. 17 is a cross-sectional view taken along line XVII-XVII in FIG. As shown in the figure, a hot melt adhesive 70 is provided between the top sheet 20 and the absorbent core 22 to bond them. A hot melt adhesive 71 is provided between the absorbent core 22 and the leak-proof sheet 29 to bond them. A hot melt adhesive 72 is provided between the leak-proof sheet 29 and the back sheet 21 for bonding them.
　図示例のおむつ１０Ｂでは、レッグ弾性部材５８Ａは、トップシート２０と、防漏シート２９との間において、ホットメルト接着剤７０、７１の少なくともいずれか一方を介して収縮可能なように伸長状態でいずれか一方のシート２０、２９に取り付けてある点のみが上述したおむつ１０と異なり、他の点は同一である。 In the illustrated diaper 10 </ b> B, the leg elastic member 58 </ b> A is stretched between the top sheet 20 and the leak-proof sheet 29 so as to be shrinkable via at least one of the hot melt adhesives 70 and 71. Only the point attached to either one of the sheets 20 and 29 is different from the diaper 10 described above, and the other points are the same.
　また、折曲案内弾性部材６０Ｂは、バックシート２１と、防漏シート２９との間において、折曲案内弾性部材６０Ｂに直接塗布した接着剤によって、いずれか一方のシート２１、２９に取り付けてある。図示例のおむつ１０Ｂでは、折曲案内弾性部材６０Ｂは、バックシート２１に取り付けてある。
　すなわち、このおむつ１０Ｂは、おむつ１０に比して、上記厚さ方向において、レッグ弾性部材５８Ａと折曲案内弾性部材６０Ｂとの位置を変え、かつ、挟持しているシートが異なっている。 Further, the bending guide elastic member 60B is attached to any one of the sheets 21 and 29 with an adhesive directly applied to the bending guide elastic member 60B between the back sheet 21 and the leak-proof sheet 29. . In the illustrated diaper 10 </ b> B, the bending guide elastic member 60 </ b> B is attached to the backsheet 21.
That is, the diaper 10B is different from the diaper 10 in that the positions of the leg elastic member 58A and the bending guide elastic member 60B are changed and the sandwiched sheets are different in the thickness direction.
　図１８は、折曲案内弾性部材６０Ｂの作用を説明する図である。
　かかるおむつ１０Ｂでは、折曲案内弾性部材６０Ｂの収縮力によって、パッケージからおむつ１０Ｂを取り出せば、図１８に示すように、本体部２２ａに対してコア前端部２２ｂを非肌対向面側に起立させることができる。よって、着用する前に折曲案内部２４が視認できるように前ウエスト域１２が折れ曲がる。換言すれば、着用する前に折曲案内部２４において簡易的に折り目を付けることができるため、折曲案内部２４に沿って前ウエスト域１２を確実に折り曲げることができる。また、折曲案内弾性部材６０Ｂの中間部６１ｃは、隣接するシート２１、２９と非接合としてあるため、中間部６１ｃにおいて折曲案内弾性部材６０Ｂのみ収縮するが、隣接するシート２１、２９が中間部６１ｃに引っ張られることがない。 FIG. 18 is a diagram for explaining the operation of the bending guide elastic member 60B.
In the diaper 10B, when the diaper 10B is taken out of the package by the contraction force of the bending guide elastic member 60B, the core front end 22b is raised on the non-skin facing surface side with respect to the main body 22a as shown in FIG. be able to. Therefore, the front waist region 12 bends so that the bending guide part 24 can be visually recognized before wearing. In other words, the fold guide portion 24 can be easily creased before being worn, so that the front waist region 12 can be reliably bent along the fold guide portion 24. Further, since the intermediate portion 61c of the bending guide elastic member 60B is not joined to the adjacent sheets 21 and 29, only the bending guide elastic member 60B contracts at the intermediate portion 61c, but the adjacent sheets 21 and 29 are intermediate. It is not pulled by the part 61c.
　図１９は、おむつ１０Ｂの前ウエスト域１２を非肌対向面に向けて折り曲げた状態を示す図である。図示するように、折曲案内弾性部材６０Ｂは、上端部６１ａと下端部６１ｂとが厚さ方向に接近することで、中間部６１ｃにおいて、弛んだ状態となっており、収縮力が作用していない。
　前ウエスト域１２を非肌対向面に向けて折り曲げ、吸収性コア２２よりも非肌対向面側に折曲案内弾性部材６０Ｂを配置し、折曲案内弾性部材６０Ｂの上下端部６１ａ、６１ｂのみをシート２１、２９に取り付ける一方、中間部６１ｃをシート２１、２９に非接着とするため、折曲案内弾性部材６０Ｂは縮んだ状態となり、収縮力が作用しない。よって、前ウエスト域１２を折り曲げた状態で着用しても、着用した状態では、折曲案内弾性部材６０Ｂの収縮力が作用することを防止して、おむつ１０Ｂが身体からずれることを防止することができる。しかも、着用者がおむつ１０Ｂを装着する時において、折曲部位端部６３が折曲案内弾性部材６０Ｂの収縮力により引っ張られて湾曲状になってしまう事を防止することができ、折曲部位端部６３が相互に浮き上がることなしに折曲部位端部６３が横軸Ｑとほぼ並行に延びることができるため、予め設定した状態で装着することができる。よって、着用者が装着した状態において、おむつ１０Ｂがずれることを確実に防止することができる。
　加えて、厚さ方向において、レッグ弾性部材５８Ａと折曲案内弾性部材６０Ｂとの位置を変え、かつ、不図示のホットメルト接着剤によって取り付けるシートを変えているため、弾性部材５８Ａ、６０Ｂを取り付けるシートに起因して発生する浮き上がりを抑えることができる。なお、折曲案内部２４は、非肌対向面に設けてもよい。 FIG. 19 is a diagram showing a state where the front waist region 12 of the diaper 10B is bent toward the non-skin facing surface. As shown in the figure, the bending guide elastic member 60B is in a slack state in the intermediate portion 61c due to the upper end 61a and the lower end 61b approaching in the thickness direction, and contraction force is acting. Absent.
The front waist region 12 is bent toward the non-skin facing surface, the bending guide elastic member 60B is disposed closer to the non-skin facing surface than the absorbent core 22, and only the upper and lower ends 61a and 61b of the bending guide elastic member 60B Is attached to the sheets 21 and 29, and the intermediate portion 61c is not adhered to the sheets 21 and 29, so that the bending guide elastic member 60B is contracted, and no contraction force acts. Therefore, even if it wears in the state where the front waist region 12 was bent, in the worn state, it prevents that the contraction force of bending guide elastic member 60B acts, and prevents diaper 10B from shifting from a body. Can do. Moreover, when the wearer wears the diaper 10B, the bent portion end 63 can be prevented from being bent due to the contraction force of the bending guide elastic member 60B, and the bent portion can be prevented. Since the bent portion end 63 can extend substantially in parallel with the horizontal axis Q without the ends 63 being lifted from each other, it can be mounted in a preset state. Therefore, in the state where the wearer is wearing, the diaper 10B can be reliably prevented from shifting.
In addition, since the positions of the leg elastic member 58A and the bending guide elastic member 60B are changed in the thickness direction and the sheet to be attached is changed by a hot melt adhesive (not shown), the elastic members 58A and 60B are attached. Lifting caused by the sheet can be suppressed. In addition, you may provide the bending guide part 24 in a non-skin opposing surface.
　なお、この発明は、上述した第１実施形態に限られず、種々の変更を行なうことができる。
　例えば、図１～１９に示す例では、折曲案内部２４、２４Ａにおける吸収性コア２２の肌対向面から非肌対向面への厚さ方向の寸法を本体部２２ａの厚さ方向の寸法よりも薄いもので説明した。しかし、この発明はそれに限られず、折曲案内部２４、２４Ａは、折曲案内部２４、２４Ａに相当する部位の吸収性コア２２を予め設けないこと、および吸収性コア２２の一部を取り除くことによって、吸収性コア２２が実質的に存在しないように形成してもよい。吸収性コア２２が実質的に存在しないように折曲案内部２４、２４Ａを形成すれば、吸収性コア２２が存在しない部位の剛性を低下することができるため、剛性の相違を明確にすることができる。よって、折曲案内弾性部材６０、６０Ａ、６０Ｂの収縮力を一定に仮定した場合、折曲案内部２４、２４Ａにおける簡易的な折り目を大きくすることができる。 The present invention is not limited to the first embodiment described above, and various changes can be made.
For example, in the examples shown in FIGS. 1 to 19, the dimension in the thickness direction from the skin facing surface to the non-skin facing surface of the absorbent core 22 in the bending guide portions 24 and 24A is larger than the dimension in the thickness direction of the main body portion 22a. The explanation was also thin. However, the present invention is not limited to this, and the bending guide portions 24 and 24A are not provided with the absorbent core 22 corresponding to the bending guide portions 24 and 24A in advance, and a part of the absorbent core 22 is removed. Thus, the absorbent core 22 may be formed so as not to substantially exist. If the bending guide portions 24 and 24A are formed so that the absorbent core 22 does not substantially exist, the rigidity of the portion where the absorbent core 22 does not exist can be lowered, so that the difference in rigidity is clarified. Can do. Therefore, when the contraction force of the bending guide elastic members 60, 60A, 60B is assumed to be constant, a simple crease in the bending guide portions 24, 24A can be increased.
　図２０は、第２実施形態のおむつ１０Ｃを展開した状態において、肌対向面から見た一部破断展開平面図である。図２１は、この発明にかかるおむつ１０Ｃの要部を示す図である。
　このおむつ１０Ｃにおいて、上述したおむつ１０と同一の構成を有するものには同一の符号を付して説明を省略する。 FIG. 20 is a partially broken developed plan view as seen from the skin facing surface in a state where the diaper 10 </ b> C of the second embodiment is developed. FIG. 21 is a view showing a main part of a diaper 10C according to the present invention.
In this diaper 10 </ b> C, the same reference numerals are given to those having the same configuration as the above-described diaper 10, and description thereof is omitted.
　図示例のおむつ１０Ｃにおいて、縦方向Ｙにおける前ウエスト域１２の長さ寸法１２Ｌは約６０ｍｍであり、縦方向Ｙにおける後ウエスト域１３の長さ寸法１３Ｌは約６０ｍｍであり、縦方向Ｙにおけるクロッチ域１４の長さ寸法１４Ｌは約２４０ｍｍである。 In the illustrated diaper 10C, the length 12L of the front waist region 12 in the longitudinal direction Y is about 60 mm, the length 13L of the rear waist region 13 in the longitudinal direction Y is about 60 mm, and the crotch in the longitudinal direction Y The length dimension 14L of the zone 14 is about 240 mm.
　このおむつ１０Ｃのバリヤ弾性部材５９Ｃの下端部Ｃ１は、縦方向Ｙにおいて、本体部２２ａの対向縁部２４ｂを超えて下方へ延び、かつ溝である折曲案内部２４の内部においてさらに下方へ延び、コア前端部２２ｂの対向縁部２４ａにまで到達する。換言すれば、このバリヤ弾性部材５９Ｃは、展開状態において、折曲案内部２４に重なる態様で縦方向Ｙに延びるものである。
　このバリヤ弾性部材５９Ｃは、その収縮力を作用させることによって、本体部２２ａに対してコア前端部２２ｂを起立させる弾性部材として機能する。 The lower end portion C1 of the barrier elastic member 59C of the diaper 10C extends in the longitudinal direction Y beyond the opposing edge portion 24b of the main body portion 22a, and further extends downward in the bending guide portion 24 that is a groove. And reaches the opposite edge 24a of the core front end 22b. In other words, the barrier elastic member 59 </ b> C extends in the longitudinal direction Y so as to overlap the bending guide portion 24 in the unfolded state.
The barrier elastic member 59C functions as an elastic member for raising the core front end portion 22b with respect to the main body portion 22a by applying the contraction force.
　バリヤ弾性部材５９Ｃは、約４７０ｄｔｅｘのストリング状のものを縦軸Ｐの両側にそれぞれ２本ずつ設けてあり、約２．４倍に伸長させることによって、収縮力が作用するようにバリヤシート３０、３１に取り付けてある。 The barrier elastic member 59C is provided with two string-like members of about 470 dtex on each side of the longitudinal axis P, and the barrier sheet 30, so that the contraction force acts by extending about 2.4 times. 31 is attached.
　後ウエスト域１３において、バリヤシート３０、３１をトップシート２０に取り付ける後固定端部５６は、通常のおむつと同様であって、縦方向Ｙの長さ寸法５６Ｌは６０ｍｍである。
　一方、前ウエスト域１２において、バリヤシート３０、３１をトップシート２０に取り付ける前固定端部５５Ｃは、上記厚さ方向において、コア前端部２２ｂに重なるように配置してあり、かつ折曲案内部２４および本体部２２ａに重ならないように配置してある。また、この前固定端部５５Ｃは、通常のおむつに比して短くしてあって、縦方向Ｙの長さ寸法５５Ｌは４０ｍｍである。 In the rear waist region 13, the rear fixed end portion 56 for attaching the barrier sheets 30, 31 to the top sheet 20 is the same as a normal diaper, and the length dimension 56L in the longitudinal direction Y is 60 mm.
On the other hand, in the front waist region 12, the front fixed end portion 55C for attaching the barrier sheets 30 and 31 to the top sheet 20 is disposed so as to overlap the core front end portion 22b in the thickness direction, and the bending guide portion. 24 and the main body 22a are arranged so as not to overlap. The front fixed end 55C is shorter than a normal diaper, and the length dimension 55L in the vertical direction Y is 40 mm.
　図２２は、おむつ１０Ｃの着用前の状態を示す図である。図示するように、かかるおむつ１０Ｃでは、バリヤ弾性部材５９Ｃの収縮力によってバリヤシート３０、３１がトップシート２０の肌対向面から離間し、尿等の体液の横漏れを防ぐためのバリヤカフ６５が形成される。このとき、バリヤ弾性部材５９Ｃの収縮力によって、パッケージからおむつ１０Ｃを取り出せば、本体部２２ａに対してコア前端部２２ｂを肌対向面側に起立させることができる。よって、着用する前に折曲案内部２４が視認できるように前ウエスト域１２が肌対向面側に折れ曲がる。換言すれば、着用する前に折曲案内部２４において簡易的に折り目を付けることができるため、折曲案内部２４に沿って前ウエスト域１２を確実に折り曲げることができる。
　しかも、バリヤ弾性部材５９Ｃは、バリヤカフ６５を形成するための機能と、簡易的な折り目を形成するため機能とを有するため、上記機能を有する弾性部材を個別に設ける必要がなく、構成を簡単にすることができる。
　加えて、縦方向Ｙにおいて後固定端部５６の長さ寸法５５Ｌより前固定端部５５Ｃの長さ寸法が短いため、簡易的な折り目を大きくすることができる。
　なお、この発明は、上述した第２実施形態に限られず、種々の変更を行なうことができる。例えば、第１実施形態と同様の変形を行なうことができる。 Drawing 22 is a figure showing the state before wearing of diaper 10C. As shown in the figure, in the diaper 10C, the barrier sheets 30 and 31 are separated from the skin-facing surface of the top sheet 20 by the contraction force of the barrier elastic member 59C, and a barrier cuff 65 is formed to prevent side leakage of body fluid such as urine. Is done. At this time, if the diaper 10C is taken out of the package by the contraction force of the barrier elastic member 59C, the core front end portion 22b can be erected on the skin facing surface side with respect to the main body portion 22a. Therefore, the front waist region 12 is bent toward the skin facing surface side so that the bending guide portion 24 can be visually recognized before wearing. In other words, the fold guide portion 24 can be easily creased before being worn, so that the front waist region 12 can be reliably bent along the fold guide portion 24.
In addition, since the barrier elastic member 59C has a function for forming the barrier cuff 65 and a function for forming a simple crease, it is not necessary to separately provide an elastic member having the above function, and the configuration can be simplified. can do.
In addition, since the length dimension of the front fixed end portion 55C is shorter than the length dimension 55L of the rear fixed end portion 56 in the longitudinal direction Y, a simple crease can be increased.
The present invention is not limited to the second embodiment described above, and various modifications can be made. For example, the same modification as that of the first embodiment can be performed.
