Moreover, the dimension W2 of the horizontal direction X of the absorption panel 16 is 150-220 mm. Therefore, the dimension W2 in the lateral direction X of the absorbent panel 16 is 27 to 36% of the dimension W1 in the lateral direction X of the diaper 10 and is larger than that of a general diaper (especially for adults). 16 can be said to be narrow.

吸収パネル１６は、前後端縁１６ａ，１６ｂと両側縁１６ｃ，１６ｄとによって画定された縦長方形状であって、前後端部１９Ａ，１９Ｂが、前後ウエストパネル１４，１５の肌対向面にホットメルト接着剤を塗布してなる前後接合域（図示せず）を介して互いに接合されている。前後接合域におけるホットメルト接着剤の塗布パターンは、例えば、縦方向Ｙへ延びる複数のライン状のほかに、Ω状、スパイラル状、波状等の各種公知の形状を採用することができる。   The absorbent panel 16 has a vertical rectangular shape defined by front and rear end edges 16a and 16b and both side edges 16c and 16d, and the front and rear end portions 19A and 19B are hot-melted on the skin facing surfaces of the front and rear waist panels 14 and 15, respectively.

図２及び図３を参照すると、吸収パネル１６は、肌対向面側に位置する親水性／透液性の内面シート（身体側ライナ）３１と吸収体３３とから構成された吸液構造体３０と、吸液構造体３０の非肌対向面側に位置する疎水性の被覆シート３２と、吸液構造体３０の非肌対向面側において、少なくともその底面を被覆する大きさを有する疎水性又不透液性の防漏フィルム３４とを有する。吸収体３３は、吸液性コア３５と吸液性コア３５の全体を包被するコアラップシート３６とを有する。   Referring to FIG. 2 and FIG. 3, the absorbent panel 16 includes a liquid absorbing structure 30 including a hydrophilic / liquid permeable inner surface sheet (body side liner) 31 and an absorbent body 33 that are located on the skin facing surface side. A hydrophobic coating sheet 32 positioned on the non-skin facing surface side of the liquid absorbing structure 30, and a hydrophobic or hydrophobic sheet having a size covering at least the bottom surface on the non-skin facing surface side of the liquid absorbing structure 30. And a liquid-impervious leak-proof film 34. The absorbent body 33 includes a liquid absorbent core 35 and a core wrap sheet 36 that covers the entire liquid absorbent core 35.

吸液性コア３５は、所要の形状に賦形された半剛性のパネル形状であって、横方向Ｘへ延びる前後端縁と、前後端縁間において縦断中心線Ｐに向かって（横方向Ｘの内側へ向かって）凸曲して延びる両側縁３５ｃ，３５ｄとを有する。また、吸液性コア３５は、フラッフ木材パルプと、超吸収性ポリマー粒子（ＳＡＰ）との混合物から形成されている。着用物品が大人用かつ軽失禁用のおむつとして使用されるときには、吸液性コア３５の厚さ寸法が比較的に小さいことが好ましく、例えば、ＳＡＰの質量をフラッフ木材パルプの質量に対して相対的に小さくすることによって、所要の吸水量を保持しつつ、その厚さ寸法を小さくしてもよいし、また、吸液性コア３５をＳＡＰのみから形成してもよい。   The liquid-absorbent core 35 has a semi-rigid panel shape shaped into a required shape, and extends toward the longitudinal center line P between the front and rear end edges extending in the lateral direction X and the front and rear end edges (lateral direction X And both side edges 35c and 35d extending in a convex manner. The liquid absorbent core 35 is formed of a mixture of fluffed wood pulp and super absorbent polymer particles (SAP). When the wearing article is used as a diaper for adults and light incontinence, it is preferable that the thickness dimension of the absorbent core 35 is relatively small. For example, the mass of SAP is relative to the mass of fluff wood pulp. Therefore, the thickness dimension may be reduced while maintaining a required water absorption amount, or the liquid-absorbing core 35 may be formed only from SAP.

内面シート３１とコアラップシート３６とは、親水性及び液拡散性を有するシート材料から形成されるものであって、例えば、質量１５〜２５ｇ／ｍ２の親水化処理されたスパンボンド繊維不織布、ＳＭＳ繊維不織布等から形成することができる。コアラップシート３６は、内面シート３１と同種類のシート材料から形成することもできるが、好適には、ティッシュペーパから形成される。また、その厚さ寸法は、内面シート３１のそれに比べて小さく、吸液性コア３５を所要形状に保形できる程度の強度を実現する厚さ寸法であればよい。被覆シート３２は、疎水性又は実質的に不透液性のシート材料から形成されており、例えば、質量１５〜３０ｇ／ｍ２のＳＭＳ繊維不織布やスパンボンド不織布等から形成される。防漏フィルム３４は、好ましくは通気性を有する、疎水性のシート材料、例えば、質量１０〜２５ｇ／ｍ２の通気性プラスチックフィルムから形成される。 The inner surface sheet 31 and the core wrap sheet 36 are formed from a sheet material having hydrophilicity and liquid diffusibility. For example, a spunbond fiber nonwoven fabric having a mass of 15 to 25 g / m 2 and subjected to hydrophilic treatment, It can be formed from an SMS fiber nonwoven fabric or the like. The core wrap sheet 36 can be formed from the same type of sheet material as the inner sheet 31, but is preferably formed from tissue paper. Moreover, the thickness dimension should just be a thickness dimension which implement | achieves the intensity | strength which is small compared with that of the inner surface sheet 31, and can hold the liquid-absorbing core 35 in a required shape. The covering sheet 32 is formed from a hydrophobic or substantially liquid-impervious sheet material, and is formed from, for example, an SMS fiber nonwoven fabric or a spunbond nonwoven fabric having a mass of 15 to 30 g / m 2 . The leak-proof film 34 is preferably formed of a hydrophobic sheet material having air permeability, for example, an air-permeable plastic film having a mass of 10 to 25 g / m 2 .

図４及び図５を参照すると、吸液構造体３０において、吸液性コア３５の肌対向面側を被覆する内面シート３１は、吸液性コア３５の両側縁３５ｃ，３５ｄからさらに横方向Ｘの外側へ延びている。具体的には、内面シート３１は、吸液性コア３５の両側縁３５ｃ，３５ｄから吸収パネル１６の両側縁１６ｃ，１６ｄ近傍まで延び、吸収パネル１６の両側縁１６ｃ，１６ｄに沿って縦方向Ｙへ延びる折曲ライン３１ｃに沿って折り曲げられた後、縦断中心線Ｐへ向かって延び、その外側縁部３１ｂが吸液性コア３５の非肌対向面側に位置している。また、吸液性コア３５を包被するコアラップシート３６は、吸液性コア３５の外形寸法よりもひとまわり大きな外形を有する。内面シート３１とコアラップシート３６とは、それぞれ、吸液性コア３５の両側縁３５ｃ，３５ｄから横方向Ｘの外側へ延びる延出部分３１Ａ，３６Ａを有し、これら延出部分３１Ａ，３６Ａによって、吸液性コア３５の横方向Ｘの外側には親水性層（液拡散性層）５０が形成される。   Referring to FIGS. 4 and 5, in the liquid absorbing structure 30, the inner surface sheet 31 that covers the skin facing surface side of the liquid absorbing core 35 is further laterally extended from both side edges 35 c and 35 d of the liquid absorbing core 35. Extends outward. Specifically, the inner surface sheet 31 extends from both side edges 35c and 35d of the liquid absorbent core 35 to the vicinity of both side edges 16c and 16d of the absorbent panel 16, and the longitudinal direction Y along the both side edges 16c and 16d of the absorbent panel 16 After being bent along the bending line 31 c extending toward the center, it extends toward the longitudinal center line P, and the outer edge 31 b is located on the non-skin facing surface side of the liquid absorbent core 35. The core wrap sheet 36 that encloses the liquid absorbent core 35 has an outer shape that is slightly larger than the external dimensions of the liquid absorbent core 35. The inner surface sheet 31 and the core wrap sheet 36 have extension portions 31A and 36A extending from both side edges 35c and 35d of the liquid-absorbent core 35 to the outside in the lateral direction X, respectively, and the extension portions 31A and 36A A hydrophilic layer (liquid diffusible layer) 50 is formed outside the liquid-absorbent core 35 in the lateral direction X.

親水性層５０は、内面シート３１とコアラップシート３６との折り重ねた延出部分３１Ａ，３６Ａから形成されていることから４層構造を有する。ただし、所要の保液性能を有する限りにおいて、内面シート３１の延出部分３１Ａとコアラップシート３６の延出部分３６Ａとは、４層構造ではなく２層構造であってもよいし、親水性層５０が内面シート３１の延出部分３１Ａのみから形成されていてもよい。また、吸液性コア３５の両側縁３５ｃ、３５ｄが凹曲状を有していることから、親水性層５０はクロッチ域１３の中央部においてその横方向Ｘの寸法Ｗ５が最も大きく、前後ウエスト域１１，１２において該寸法Ｗ５が最も小さくなっている。   The hydrophilic layer 50 has a four-layer structure because it is formed from the extended portions 31 </ b> A and 36 </ b> A of the inner sheet 31 and the core wrap sheet 36. However, as long as it has the required liquid retention performance, the extended portion 31A of the inner surface sheet 31 and the extended portion 36A of the core wrap sheet 36 may have a two-layer structure instead of a four-layer structure, and are hydrophilic. The layer 50 may be formed only from the extending portion 31 </ b> A of the inner surface sheet 31. Further, since both side edges 35c and 35d of the liquid-absorbent core 35 are concavely curved, the hydrophilic layer 50 has the largest dimension W5 in the lateral direction X in the central portion of the crotch region 13, and the front and rear waists. In the areas 11 and 12, the dimension W5 is the smallest.

図３（ｃ）及び図４，５を参照すると、第２折曲ライン４４に沿って折り曲げられた状態において、両側部４２のうちの親水性層５０の肌対向面側に折り重ねられた部分は、吸収パネル１６の両側縁１６ｃ，１６ｄに沿って縦方向Ｙに延びる外側接合域４６と外側接合域４６の横方向Ｘの内側に位置する内側接合域４７と、前後ウエスト域１１，１２において内側接合域４７のさらに横方向Ｘの内側に位置する端部接合域４８とを介して固定する。また、親水性層５０の非肌対向面側に位置する外側縁部は、外側接合域４６と厚さ方向において対向する接合域４９を介して親水性層５０の非肌対向面側に接合する。なお、図示していないが、本明細書において特に記載しない限りにおいて、厚さ方向Ｚにおいて積層されているシートどうしは、それらのシートの互いに対向する面の少なくとも一方に塗布された接着剤によって固定されている。   Referring to FIG. 3 (c) and FIGS. 4 and 5, a portion folded on the skin facing surface side of the hydrophilic layer 50 in the both side portions 42 in a state of being folded along the second folding line 44. In the outer joint area 46 extending in the longitudinal direction Y along the side edges 16c and 16d of the absorbent panel 16, the inner joint area 47 located inside the lateral direction X of the outer joint area 46, and the front and rear waist areas 11 and 12 It fixes via the edge part junction area 48 located in the inner side of the horizontal direction X of the inner junction area 47 further. In addition, the outer edge located on the non-skin facing surface side of the hydrophilic layer 50 is joined to the non-skin facing surface side of the hydrophilic layer 50 via a joining region 49 facing the outer joining region 46 in the thickness direction. . Although not shown, unless otherwise specified in the present specification, the sheets stacked in the thickness direction Z are fixed by an adhesive applied to at least one of the surfaces of the sheets facing each other. Has been.

図３（ｂ）及び図４，５を参照すると、両側部４２における折曲状態の被覆シート３２の間には、第２折曲ライン４４に沿って縦方向Ｙへ延びる複数条のストリング状又はストランド状のカフ弾性体６４が伸長状態で収縮可能に配置されている。また、被覆シート３２の外側縁部側には、両側部４２と防漏フィルム３４との間において、縦方向Ｙへ延びる複数条のストリング状又はストランド状のレッグ弾性体（ガスケットカフ弾性体）６５が伸長状態で収縮可能に取り付けられている。   Referring to FIG. 3B and FIGS. 4 and 5, a plurality of string-like shapes extending in the longitudinal direction Y along the second bent line 44 between the cover sheets 32 in the bent state in the side portions 42 or A strand-shaped cuff elastic body 64 is disposed in a stretched state so as to be contractible. Further, a plurality of string-like or strand-like leg elastic bodies (gasket cuff elastic bodies) 65 extending in the longitudinal direction Y between the both side portions 42 and the leak-proof film 34 on the outer edge side of the covering sheet 32. Is attached to be retractable in an extended state.

カフ弾性体６４には、例えば、太さ（線径）が４７０〜７４０ｄｔｅｘであって、収縮又は弛緩された状態から２．５〜３．２倍に伸長されて固定された弾性材料を用いることができる。図４を参照すると、カフ弾性体６４の横方向Ｘの離隔寸法Ｗ６は、３〜８ｍｍである。   For the cuff elastic body 64, for example, an elastic material having a thickness (wire diameter) of 470 to 740 dtex and stretched and fixed 2.5 to 3.2 times from a contracted or relaxed state is used. Can do. Referring to FIG. 4, the separation dimension W6 in the lateral direction X of the cuff elastic body 64 is 3 to 8 mm.

レッグ弾性体６５は、例えば、太さ（線径）が４７０〜７４０ｄｔｅｘであって、収縮又は弛緩された状態から１．７〜２．３倍に伸長されて固定された弾性材料を用いることができる。レッグ弾性体６５の横方向Ｘの離隔寸法Ｗ７は、１０〜１５ｍｍである。   The leg elastic body 65 uses, for example, an elastic material that has a thickness (wire diameter) of 470 to 740 dtex and is fixed by being expanded 1.7 to 2.3 times from a contracted or relaxed state. it can. The separation dimension W7 in the lateral direction X of the leg elastic body 65 is 10 to 15 mm.

レッグ弾性体６５の伸長倍率が、カフ弾性体６４の伸長倍率よりも小さい。また、レッグ弾性体６５の横方向Ｘの離隔寸法Ｗ７が、カフ弾性体６４の横方向Ｘの離隔寸法Ｗ６よりも大きい。   The expansion ratio of the leg elastic body 65 is smaller than the expansion ratio of the cuff elastic body 64. Further, the separation dimension W7 in the lateral direction X of the leg elastic body 65 is larger than the separation dimension W6 in the lateral direction X of the cuff elastic body 64.

図４及び図５を参照すると、吸収パネル１６は、かかる構成を有することによって、縦方向Ｙへ延びる一対の防漏カフ６０と、防漏カフ６０の横方向Ｘの外側に位置する一対のサイド延出部（ガスケットカフ）６１とをさらに有する。防漏カフ６０は、第１折曲ライン４３で折り曲げられた２枚の被覆シート３２から構成された２層構造を有する。換言すれば、防漏カフ６０は、２枚の被覆シート３２から構成されている。防漏カフ６０は、被覆シート３２の両側部４２のうちの端部接合域４８を介して内面シート３１に固定された両端固定部と、内側接合域４７を介して内面シート３１に固定された縦方向Ｙへ延びる基端部（近位部）６２と、両端固定部間において縦方向Ｙへ延び、かつ、基端部６２と並行して縦方向Ｙへ延びる自由部（遠位部）６３とを有する。自由部６３には、カフ弾性体６４が伸長状態で収縮可能に配設されているため、着用状態において、カフ弾性体６４が収縮することによって、該縁部が内面シート３１から着用者の身体側へ離隔し、着用者の大腿部にフィットして体液の漏れを防止する。   Referring to FIGS. 4 and 5, the absorption panel 16 has such a configuration, and thus a pair of leak-proof cuffs 60 extending in the vertical direction Y and a pair of sides located outside the lateral direction X of the leak-proof cuff 60. It further has an extension part (gasket cuff) 61. The leak-proof cuff 60 has a two-layer structure composed of two covering sheets 32 bent along the first bending line 43. In other words, the leak-proof cuff 60 is composed of two covering sheets 32. The leak-proof cuff 60 is fixed to the inner surface sheet 31 via the inner joint region 47 and the both-end fixing portion fixed to the inner surface sheet 31 via the end joint region 48 of the both side portions 42 of the covering sheet 32. A base end portion (proximal portion) 62 extending in the vertical direction Y, and a free portion (distal portion) 63 extending in the vertical direction Y between the both end fixing portions and extending in the vertical direction Y in parallel with the base end portion 62. And have. Since the cuff elastic body 64 is disposed in the free portion 63 so as to be contractible in an extended state, the cuff elastic body 64 contracts in the worn state, so that the edge portion is separated from the inner surface sheet 31 by the wearer's body. Separate to the side and fit on the wearer's thigh to prevent fluid leakage.

本実施形態において、防漏カフ６０及びサイド延出部６１の一部は、被覆シート３２から形成されているが、防漏カフ６０は、被覆シート３２と別体のシート材料から形成されていてもよい。かかるときには、防漏カフ６０は、主として体液の漏れを防止するものであるから、必ずしも不透液性のシートから形成する必要はない。   In this embodiment, the leak-proof cuff 60 and a part of the side extension 61 are formed from the cover sheet 32, but the leak-proof cuff 60 is formed from a sheet material separate from the cover sheet 32. Also good. In such a case, since the leak-proof cuff 60 mainly prevents leakage of body fluid, it is not necessarily formed from a liquid-impermeable sheet.

図４及び図５を参照すると、吸収パネル１６のサイド延出部６１は、内面シート３１の延出部分３１Ａとコアラップシート３６の延出部分３６Ａとから構成された親水性層５０と、親水性層５０を厚さ方向Ｚにおいて覆う疎水性層５１，５２とを有する。疎水性層５１，５２は、親水性層５０の非肌対向面側を被覆する第１疎水性層（下側層）５１と、親水性層５０の肌対向縁側を被覆する第２疎水性層（上側層）５２とを有する。第１疎水性層５１は、被覆シート３２の主体部４１と、外側縁部４２Ａ及び防漏フィルム３４とから構成された３層構造を有し、第２疎水性層５２は、被覆シート３２の折り曲げられた２枚の両側部４２から構成された２層構造を有する。親水性層５０は、折り曲げられた２枚の内面シート３１と、折り曲げられた２枚のコアラップシート３６との４層構造を有する。すなわち、サイド延出部６１を構成するシートの枚数は９枚である。第１疎水性層５１を形成する防漏フィルム３４の側縁部と被覆シート３２の外側縁部４２Ａとの間には、複数条のレッグ弾性体６５が伸長状態で収縮可能に取り付けられている。吸収パネル１６のサイド延出部６１は、第１疎水性層５１に位置するレッグ弾性体６５の収縮作用によって、少なくとも縦方向Ｙへ弾性を有する。   Referring to FIGS. 4 and 5, the side extension 61 of the absorbent panel 16 includes a hydrophilic layer 50 composed of an extension part 31 </ b> A of the inner surface sheet 31 and an extension part 36 </ b> A of the core wrap sheet 36, Hydrophobic layers 51 and 52 covering the conductive layer 50 in the thickness direction Z. The hydrophobic layers 51 and 52 are a first hydrophobic layer (lower layer) 51 that covers the non-skin facing surface side of the hydrophilic layer 50 and a second hydrophobic layer that covers the skin facing edge side of the hydrophilic layer 50. (Upper layer) 52. The first hydrophobic layer 51 has a three-layer structure including a main body portion 41 of the covering sheet 32, an outer edge portion 42 </ b> A, and a leak-proof film 34, and the second hydrophobic layer 52 is formed of the covering sheet 32. It has a two-layer structure composed of two folded sides 42. The hydrophilic layer 50 has a four-layer structure of two folded inner sheets 31 and two folded core wrap sheets 36. That is, the number of sheets constituting the side extending portion 61 is nine. Between the side edge part of the leak-proof film 34 which forms the 1st hydrophobic layer 51, and the outer edge part 42A of the coating sheet 32, the multiple leg | leg elastic body 65 is attached so that contraction is possible in the expansion | extension state. . The side extension 61 of the absorbent panel 16 has elasticity in at least the longitudinal direction Y due to the contracting action of the leg elastic body 65 located in the first hydrophobic layer 51.

このおむつ１０によれば、サイド延出部６１を形成するシートの枚数が、防漏カフ６０を形成するシートの枚数よりも多いため、サイド延出部６１の剛性が防漏カフ６０の剛性よりも高い。加えて、レッグ弾性体６５の伸長倍率が、カフ弾性体６４の伸長倍率よりも小さく、レッグ弾性体６５間の横方向Ｘの離隔寸法が、カフ弾性体６４間の横方向Ｘの離隔寸法よりも大きい。サイド延出部が、単層、又は２、３層の積層構造であるときには、クロッチ域の後ウエスト域側において、着用中にサイド延出部が捲かれて臀部が露出するおそれがあるが、サイド延出部６１の剛性が比較的に高いことによって身体にサイド延出部６１が安定的に当接し、サイド延出部６１が横方向Ｘの内側に入ることを抑えることができ、吸収パネル１６の後ウエスト域１２側によって臀部を覆った状態を維持することができる。しかも、レッグ弾性体６５の伸長倍率が、カフ弾性体６４の伸長倍率よりも小さいことから、サイド延出部６１が防漏カフ６０とともに身体に向かって起立せずに、横方向Ｘの外側へ突出したような態様となるため、大腿部の内側に面状に当接させることができる。また、縦方向において、前ウエスト域の寸法よりも後ウエスト域の寸法を大きくすることによって、後ウエストパネルの下端部に臀部カバーを有するおむつでは、着用状態において、フラップ状の臀部カバーが着用者の身体に食い込むような状態となり、身体にフィットした着衣を着用したとき等には、かかる食い込みによる身体とおむつとの段差状のラインが着衣の上から視認され、特に女性にとっては、おむつ１０の着用に対する抵抗感を与える原因となるおそれがある。本実施形態にかかるおむつ１０では、サイド延出部６１が比較的に高い剛性を有することによって、着用状態において、臀部を覆うクロッチ域１３の後ウエスト域１２側が身体に食い込み難くなり、身体にフィットした着衣を着用しても、着衣の上からおむつ１０と身体とによる段差状のラインが視認されることはなく、おむつ１０を初めて着用する着用者に、着用することに対する抵抗感を低減することができる。   According to this diaper 10, the number of sheets forming the side extension portion 61 is larger than the number of sheets forming the leakage prevention cuff 60, so the rigidity of the side extension portion 61 is greater than the rigidity of the leakage prevention cuff 60. Is also expensive. In addition, the expansion ratio of the leg elastic body 65 is smaller than the expansion ratio of the cuff elastic body 64, and the separation dimension in the lateral direction X between the leg elastic bodies 65 is larger than the separation dimension in the lateral direction X between the cuff elastic bodies 64. Is also big. When the side extension part is a single layer or a laminated structure of two or three layers, on the rear waist area side of the crotch area, there is a possibility that the side extension part is crushed during wearing and the buttock part is exposed, Since the side extension 61 has a relatively high rigidity, the side extension 61 can stably come into contact with the body, and the side extension 61 can be prevented from entering inside the lateral direction X. The state which covered the buttocks by the back waist area 12 side of 16 can be maintained. In addition, since the expansion ratio of the leg elastic body 65 is smaller than the expansion ratio of the cuff elastic body 64, the side extension portion 61 does not stand together with the leak-proof cuff 60 toward the body and moves outward in the lateral direction X. Since it becomes the aspect which protruded, it can be made to contact | abut on the inner side of a thigh in planar shape. In the diaper having a buttock cover at the lower end of the rear waist panel by making the size of the rear waist region larger than the size of the front waist region in the vertical direction, the flap-like buttock cover is worn by the wearer in the wearing state. When wearing clothing that fits the body, etc., a step-like line between the body and the diaper due to such biting is visible from above the clothing, and especially for women, the diaper 10 May cause resistance to wear. In the diaper 10 according to the present embodiment, the side extension portion 61 has a relatively high rigidity, so that the rear waist region 12 side of the crotch region 13 that covers the buttocks is difficult to bite into the body in a worn state, and fits the body. Even if the worn garment is worn, a step-like line between the diaper 10 and the body is not visually recognized from above the garment, and the wearer who wears the diaper 10 for the first time is reduced in resistance to wearing. Can do.

また、レッグ弾性体６５間の横方向Ｘの離隔寸法（ピッチ）は、カフ弾性体６４間の横方向の離隔寸法（ピッチ）よりも大きいことから、サイド延出部６１に形成されるギャザー（横皺）６１ａは、防漏カフ６０の自由部６３に形成されるギャザー（横皺）６０ａに比して大きい。サイド延出部６１に比較的に大きな複数のギャザー６１ａが形成されることから、大腿部とサイド延出部６１との間には空気の流路となる複数の隙間が形成され、おむつ１０の内部の蒸れを効果的に防止しうる。また、サイド延出部６１は、多層構造を有して比較的に剛性が高いことから、かかるギャザー６１ａは、安定した形状をなし、着用中に崩れて消失することはない。一方、防漏カフ６０においては、比較的に小さなギャザー６０ａが複数形成され、防漏カフ６０における単位面積当たりのギャザー６０ａの数は、サイド延出部６１における単位面積当たりのギャザー６１ａの数よりも多くなる。したがって、単位面積当たりにおいて、身体に当接する面積は、サイド延出部６１の方が防漏カフ６０よりも広くなり、防漏カフ６０は、サイド延出部６１に比べて剛性が低くても身体に安定的に当接される。サイド延出部６１の横方向Ｘの寸法が５ｍｍであって縦方向Ｙにおける長さ寸法５０ｍｍ当たりにおいて、３〜７個以上のギャザー（横皺）６１ａが形成される。また、防漏カフ６０の横方向Ｘの寸法が５ｍｍであって縦方向Ｙにおける長さ寸法５０ｍｍ当たりにおいて、８〜１５個以上のギャザー（横皺）６０ａが形成される。なお、サイド延出部６１には、親水性層５０によって尿等の体液が拡散、吸収される一方、身体を伝って体液がその肌対向面に移動するのが防漏カフ６０によって阻止されため、ギャザー６１ａによる隙間が形成されても、体液がおむつ１０の外部に漏れることはない。   Further, since the separation dimension (pitch) in the lateral direction X between the leg elastic bodies 65 is larger than the separation dimension (pitch) in the lateral direction between the cuff elastic bodies 64, the gathers ( (Bubo) 61a is larger than the gathers (Bubo) 60a formed in the free part 63 of the leak-proof cuff 60. Since a plurality of relatively large gathers 61a are formed in the side extension 61, a plurality of gaps serving as air flow paths are formed between the thigh and the side extension 61, and the diaper 10 It is possible to effectively prevent stuffiness inside. Moreover, since the side extension part 61 has a multilayer structure and is relatively high in rigidity, the gather 61a has a stable shape and does not collapse and disappear during wearing. On the other hand, in the leak-proof cuff 60, a plurality of relatively small gathers 60a are formed, and the number of gathers 60a per unit area in the leak-proof cuff 60 is greater than the number of gathers 61a per unit area in the side extension 61. Will also increase. Therefore, the area of contact with the body per unit area is larger in the side extension portion 61 than in the leakage prevention cuff 60, and the leakage prevention cuff 60 is less rigid than the side extension portion 61. Stable contact with the body. When the dimension in the lateral direction X of the side extending portion 61 is 5 mm and the length dimension is 50 mm in the longitudinal direction Y, 3 to 7 or more gathers (horizontal ribs) 61a are formed. Moreover, when the dimension in the horizontal direction X of the leak-proof cuff 60 is 5 mm and the length dimension in the vertical direction Y is 50 mm, 8 to 15 or more gathers (horizontal ribs) 60a are formed. In the side extension 61, body fluid such as urine is diffused and absorbed by the hydrophilic layer 50, while the body fluid is prevented from moving along the body to the skin-facing surface by the leak-proof cuff 60. Even if a gap is formed by the gather 61a, body fluid does not leak out of the diaper 10.

図６を参照すると、おむつ１０の着用状態において、防漏カフ６０がカフ弾性体６４の収縮作用によって着用者の身体７０側へ向かって起立し、鼠蹊部に当接される一方、サイド延出部６１は、レッグ弾性体６５の収縮力によって大腿部の付け根近傍にフィットされている。このように、おむつ１０のレッグ開口２７の縁部が、防漏カフ６０とサイド延出部６１とによって比較的に広い範囲で身体に当接されるので、防漏カフ６０のみによって体液の横漏れを防止するときに比して、体液の横漏れをより効果的に防止しうる。   Referring to FIG. 6, when the diaper 10 is worn, the leak-proof cuff 60 stands up toward the wearer's body 70 due to the contraction action of the cuff elastic body 64 and abuts against the buttocks, while the side extension. The part 61 is fitted near the base of the thigh by the contraction force of the leg elastic body 65. As described above, the edge of the leg opening 27 of the diaper 10 is brought into contact with the body in a relatively wide range by the leak-proof cuff 60 and the side extension 61, so Compared to preventing leakage, side leakage of body fluid can be prevented more effectively.

大人用のおむつを着用するときには、日常生活において、着衣の内側におむつを着用していることが外観において視認されないようにしたいという観点から、おむつ１０の厚さ寸法をできるだけ抑えるために、吸液性コアの厚さ寸法及び／又は幅寸法を小さくすることが好ましい。しかし、吸液性コアの厚さ寸法等を小さくしたときには、体液の吸液量が減少して体液を十分に保持することができないおそれがある。本実施形態にかかるおむつ１０においては、吸液性コア３５の両側縁３５ｃ，３５ｄから横方向Ｘの外側へ延びる内面シート３１の延出部分３１Ａとコアラップシート３６の延出部分３６Ａとから構成された親水性層５０が、吸収パネル１６の両側縁１６ｃ，１６ｄに沿ってサイド延出部６１まで延在していることから、親水性層５０において吸液性コア３５において吸収された体液を拡散又はそれに吸収されなかった体液を直接吸収することができ、吸液性コア３５の吸液量を超える体液を一時的に保持することができる。   When wearing a diaper for adults, in order to suppress the thickness of the diaper 10 as much as possible from the viewpoint of preventing the appearance of wearing a diaper on the inside of the garment in daily life, It is preferable to reduce the thickness dimension and / or the width dimension of the conductive core. However, when the thickness dimension or the like of the liquid-absorbent core is reduced, there is a possibility that the liquid absorption amount of the body fluid decreases and the body fluid cannot be sufficiently retained. The diaper 10 according to the present embodiment includes an extended portion 31 </ b> A of the inner surface sheet 31 and an extended portion 36 </ b> A of the core wrap sheet 36 that extend outward in the lateral direction X from both side edges 35 c and 35 d of the liquid absorbent core 35. Since the hydrophilic layer 50 thus formed extends to the side extending portions 61 along the side edges 16c and 16d of the absorbent panel 16, the body fluid absorbed in the liquid absorbent core 35 in the hydrophilic layer 50 is absorbed. The body fluid that has diffused or has not been absorbed into it can be directly absorbed, and the body fluid that exceeds the liquid absorption amount of the liquid absorbent core 35 can be temporarily retained.

図４を参照すると、このように、親水性層５０において体液を一時的に保持するためには、クロッチ域１３の中央部において親水性層５０の横方向Ｘの寸法（親水性層５０の最大幅寸法）Ｗ５は、４０〜６０ｍｍであることが好ましい。親水性層５０の横方向Ｘの寸法Ｗ５が４０ｍｍ以下では、親水性層５０において一時的に保持される体液量が比較的に小さく体液の横漏れを生じるおそれがあり、一方、横方向Ｘの寸法Ｗ５が６０ｍｍ以上では、吸収パネル１６全体の横方向の寸法が大きくなり、サイド延出部６１と大腿部との間に隙間が生じるおそれがある。また、着用状態において体液が溜まるクロッチ域１３の中央部には、吸液性コア３５の最も幅狭部分が位置しておりその吸液性能が他の部分に比して低くなっている。本実施形態においては、親水性層５０の横方向Ｘの寸法Ｗ５が、吸液性コア３５の最狭部分の横方向の寸法Ｗ４の４０〜６０％の大きさであることによって、吸液性コア３５において吸収されなかった体液を親水性層５０で保持し、体液が防漏カフ６０を越えて横漏れするのを防止することができる。   Referring to FIG. 4, in order to temporarily retain the body fluid in the hydrophilic layer 50 as described above, the dimension in the lateral direction X of the hydrophilic layer 50 in the central portion of the crotch region 13 (the maximum of the hydrophilic layer 50). Large dimension) W5 is preferably 40 to 60 mm. When the dimension W5 in the lateral direction X of the hydrophilic layer 50 is 40 mm or less, the amount of body fluid temporarily retained in the hydrophilic layer 50 is relatively small, and there is a risk of causing side leakage of body fluid, When the dimension W5 is 60 mm or more, the lateral dimension of the entire absorption panel 16 becomes large, and there is a possibility that a gap is generated between the side extension 61 and the thigh. Moreover, the narrowest part of the liquid-absorbent core 35 is located in the central part of the crotch region 13 where body fluid accumulates in a worn state, and the liquid-absorbing performance is lower than other parts. In the present embodiment, the dimension W5 in the lateral direction X of the hydrophilic layer 50 is 40 to 60% of the dimension W4 in the lateral direction of the narrowest portion of the liquid-absorbent core 35, so that the liquid-absorbing property is obtained. The body fluid that has not been absorbed in the core 35 is held by the hydrophilic layer 50, and the body fluid can be prevented from leaking beyond the leak-proof cuff 60.

また、サイド延出部６１は、親水性層５０の非肌対向面側を被覆する第１疎水性層５１と、親水性層５０の肌対向面側を被覆する第２疎水性層５２とを有することから、親水性層５０においてその両側縁部まで拡散、吸収された体液が外部に漏れ出るのを抑制することができる。さらに、サイド延出部６１において、第１及び第２疎水性層５１，５２は親水性層５０全体を包被するように被覆シート３２を折り曲げて形成しており、親水性層５０の横方向Ｘの外側にも疎水性層５１，５２が位置することから体液が外部に漏れ出ることはない。   The side extension portion 61 includes a first hydrophobic layer 51 that covers the non-skin facing surface side of the hydrophilic layer 50 and a second hydrophobic layer 52 that covers the skin facing surface side of the hydrophilic layer 50. Since it has, it can suppress that the bodily fluid which spread | diffused and was absorbed to the both-sides edge part in the hydrophilic layer 50 leaks outside. Further, in the side extension portion 61, the first and second hydrophobic layers 51, 52 are formed by bending the covering sheet 32 so as to cover the entire hydrophilic layer 50, and the lateral direction of the hydrophilic layer 50 Since the hydrophobic layers 51 and 52 are located outside X, body fluid does not leak to the outside.

第１疎水性層５１は、被覆シート３２の両側部４２、主体部４１及び防漏フィルム３４の３層構造を有し、第２疎水性層５２は、被覆シート３２の両側部４２から形成された２層構造を有しており、第１及び第２疎水性層５１，５２は複数の疎水性シートを積層して形成されたものであるから、それらが単層構造を有するときに比して、体液の防漏性に優れる。また、親水性層５０は、内面シート３１とコアラップシート３６との延出部分３１Ａ，３６Ａから構成された４層構造を有するものであって、第１及び第２疎水性層５１，５２よりも積層枚数が多い多層構造となっている。親水性層５０が多層構造を有することによって、単層構造を有するときに比してより多量の体液を一時的に保持することができる。また、自然状態（いずれの方向においてもおむつ１０に力が加えられていない状態）で吸液構造体３０における吸液性コア３５が存在する横方向Ｘの中央部の厚さ方向Ｚの寸法と、サイド延出部６１の厚さ方向Ｚの寸法とを比較した場合、同一であるか、若しくはサイド延出部６１の厚さ方向Ｚの寸法が大きい方が、サイド延出部６１の剛性を比較的高くすることができるので、臀部をカバーするような形状を維持しやすい。本実施形態では、吸液性コア３５の厚さ方向Ｚの寸法が１．５〜６．０ｍｍ、サイド延出部６１の厚さ方向Ｚの寸法が２．５〜７．０ｍｍであることが装着感や外観への影響が小さく望ましい。なお。吸液性コア３５及びサイド延出部６１の厚さ方向Ｚの寸法は、株式会社尾崎製作所製ＰＥＡＣＯＣＫダイヤルシックネスゲージＪ−Ｂを用いてそれぞれ測定できる。それらの測定は、直径５０ｍｍの円形状の測定端子を用い、１０ｇｆ／ｃｍ２の圧力になるように調整して行った。 The first hydrophobic layer 51 has a three-layer structure of both side portions 42 of the covering sheet 32, the main portion 41 and the leak-proof film 34, and the second hydrophobic layer 52 is formed from both side portions 42 of the covering sheet 32. Since the first and second hydrophobic layers 51 and 52 are formed by laminating a plurality of hydrophobic sheets, the first and second hydrophobic layers 51 and 52 are compared with those having a single layer structure. Excellent body fluid leakage. Further, the hydrophilic layer 50 has a four-layer structure composed of the extended portions 31A and 36A of the inner surface sheet 31 and the core wrap sheet 36. From the first and second hydrophobic layers 51 and 52, Has a multi-layer structure in which the number of stacked layers is large. Since the hydrophilic layer 50 has a multilayer structure, a larger amount of body fluid can be temporarily retained than when the hydrophilic layer 50 has a single-layer structure. The dimension in the thickness direction Z of the central portion in the lateral direction X in which the liquid-absorbent core 35 in the liquid-absorbent structure 30 exists in a natural state (a state in which no force is applied to the diaper 10 in any direction) When the dimension in the thickness direction Z of the side extension part 61 is compared, the rigidity of the side extension part 61 is the same or the dimension in the thickness direction Z of the side extension part 61 is larger. Since it can be made relatively high, it is easy to maintain a shape that covers the collar. In the present embodiment, the dimension in the thickness direction Z of the liquid-absorbent core 35 is 1.5 to 6.0 mm, and the dimension in the thickness direction Z of the side extending portion 61 is 2.5 to 7.0 mm. It is desirable to have little effect on the fit and appearance. Note that. The dimension in the thickness direction Z of the liquid-absorbent core 35 and the side extension 61 can be measured using a PEACOCK dial thickness gauge J-B manufactured by Ozaki Mfg. Co., Ltd. These measurements were performed using a circular measuring terminal having a diameter of 50 mm and adjusting the pressure to 10 gf / cm 2 .

さらに、後下方ウエスト弾性体２３Ｂが配置された伸縮域の伸長応力が、前下方ウエスト弾性体２０Ｂが配置された伸縮域の伸長応力よりも低いことが好ましい。吸収パネル１６の後端部１９Ｂと前端部１９Ａとは、前後下方ウエスト弾性体２０Ｂ、２３Ｂと交差してその収縮力によって横方向Ｘの寸法が縮められるところ、後端部１９Ｂの縮み量が前端部１９Ａの縮み量よりも小さくなり、後端部１９Ｂの横寸法が前端部１９Ａの横寸法よりも大きくなることから、着用する前において、着用者に対して臀部全体を被覆することができ、かつ、後ウエスト域１２側に排泄された体液を十分に吸収、保持できることを視覚上認識させることができ、安心感を与えることができる。また、前後ウエストパネル１４，１５から透視される前後端部１９Ａ，１９Ｂの横寸法が異なることから、おむつ１０の前後の識別が容易になる。また、透視された前端部１９Ａが後端部１９Ｂよりも幅狭であることに加え、吸収パネル１６の横方向Ｘの寸法が比較的に小さいことから、おむつ１０の正面視においてすっきりとした印象を与えることができる。したがって、着用者が身体にフィットした着衣を着用したときであっても、着衣の上からおむつ１０の外形がはっきりと視認されることはなく、おむつ１０を初めて着用する着用者に対して、着用することに対する抵抗感を低減することができる。   Furthermore, it is preferable that the extension stress of the stretchable region where the rear lower waist elastic body 23B is disposed is lower than the stretch stress of the stretchable region where the front lower waist elastic body 20B is disposed. The rear end portion 19B and the front end portion 19A of the absorbent panel 16 intersect with the front and rear lower waist elastic bodies 20B and 23B, and the size of the rear end portion 19B is reduced by the contraction force. Since the lateral dimension of the rear end part 19B becomes smaller than the lateral dimension of the front end part 19A, it is possible to cover the entire buttocks against the wearer before wearing. And it can be made to recognize visually that the bodily fluid excreted by the back waist area 12 side can fully be absorbed and held, and a sense of security can be given. Moreover, since the lateral dimensions of the front and rear end portions 19A and 19B seen through the front and rear waist panels 14 and 15 are different, the front and rear of the diaper 10 can be easily identified. Further, since the front end portion 19A seen through is narrower than the rear end portion 19B and the dimension in the lateral direction X of the absorbent panel 16 is relatively small, the diaper 10 has a clean impression when viewed from the front. Can be given. Therefore, even when the wearer wears a garment that fits the body, the outer shape of the diaper 10 is not clearly seen from above the garment, and the wearer wears the diaper 10 for the first time. It is possible to reduce a sense of resistance to doing.

＜伸縮域の伸長応力の測定方法＞
各伸縮域の伸長応力には、引張試験機（（株）島津製作所製）を用いて以下の方法で測定した。まず、おむつ１０（通常の大人用おむつのＭサイズであって、横方向の寸法Ｗ１が６００ｍｍ）において、シーム２５を剥離して前後ウエストパネル１４，１５を分離し、前後ウエストパネル１４，１５の内面に接着剤を介して接合された吸収パネル１６の前後端部１９Ａ，１９Ｂを両ウエストパネル１４，１５から取り外した後に、前後ウエストパネル１４，１５のそれぞれから前後下方ウエスト弾性体２０Ｂ，２３Ｂが配置された各伸縮域を１４０ｍｍの幅で切り取って各サンプルとした。次いで、サンプルの一方端部を可動治具（上チャック）、他方端部を固定治具（下チャック）にそれぞれ把持させた状態において、チャック間の距離が３００ｍｍの状態から可動治具を速度３００ｍｍ／ｍｉｎで上方へ移動させ、チャック間の距離が４２５ｍｍまで離隔させて、動きを反転し、チャック間が３００ｍｍになるまで接近させた後、再び動きを反転させてチャック間が４２５ｍｍになるまで離隔させた時点の伸長応力（Ｎ）を測定した。 <Measurement method of stretching stress in stretch zone>
The elongation stress in each stretch region was measured by the following method using a tensile tester (manufactured by Shimadzu Corporation). First, in the diaper 10 (M size of a normal adult diaper, the lateral dimension W1 is 600 mm), the seam 25 is peeled to separate the front and rear waist panels 14 and 15, and the front and rear waist panels 14 and 15 are separated. After the front and rear end portions 19A and 19B of the absorbent panel 16 joined to the inner surface with an adhesive are removed from both the waist panels 14 and 15, the front and lower waist elastic bodies 20B and 23B are respectively extended from the front and rear waist panels 14 and 15. Each stretched area was cut out with a width of 140 mm to obtain each sample. Next, in a state where one end of the sample is held by the movable jig (upper chuck) and the other end is held by the fixed jig (lower chuck), the distance between the chucks is 300 mm and the speed of the movable jig is 300 mm. The distance between chucks is separated up to 425 mm, the movement is reversed, and the distance between chucks is brought close to 300 mm, and then the movement is reversed again until the distance between chucks is 425 mm. The elongation stress (N) at the time of being made was measured.

かかる測定の結果、後下方ウエスト弾性体２３Ｂが配置された伸縮域の伸長応力が、約１６Ｎ／ｍ、前下方ウエスト弾性体２０Ｂが配置された伸縮域の伸長応力が約２１Ｎ／ｍであった。また、同様の測定方法の結果、Ｌサイズのおむつ１０では、前者が約３．５Ｎ／ｍ、後者が約１０Ｎ／ｍ、ＸＬサイズのおむつ１０では、前者が約１８Ｎ／ｍ、後者が約２３Ｎ／ｍであった。   As a result of the measurement, the extension stress of the stretch region where the rear lower waist elastic body 23B is arranged is about 16 N / m, and the extension stress of the stretch region where the front lower waist elastic body 20B is arranged is about 21 N / m. . As a result of the same measurement method, in the L size diaper 10, the former is about 3.5 N / m, the latter is about 10 N / m, and in the XL size diaper 10, the former is about 18 N / m and the latter is about 23 N. / M.

再び、図２を参照すると、既述のとおり、吸液性コア３５の両側縁３５ｃ，３５ｄは、横方向Ｘの内側へ向かって凸曲した形状を有し、クロッチ域１３の中央部において防漏カフ６０の基端部６２と最も離隔している。吸液性コア３５は、シート部材よりも剛性の高い半剛性であって、吸液性コア３５が基端部６２の近傍に位置するときには、基端部６２がその剛性の影響を受けて起立し難くなるおそれがあるが、最も体液が溜まるクロッチ域１３の中央部において基端部６２と吸液性コア３５とが最も離隔していることから、防漏カフ６０の起立が阻害されることはなく、体液の横漏れを防止することができる。   Referring to FIG. 2 again, as described above, both side edges 35c and 35d of the liquid-absorbent core 35 have a shape that is curved inward in the lateral direction X, and are prevented at the center of the crotch region 13. It is farthest from the base end 62 of the leakage cuff 60. The liquid absorbent core 35 is semi-rigid, which is higher in rigidity than the sheet member, and when the liquid absorbent core 35 is positioned in the vicinity of the base end portion 62, the base end portion 62 is raised by the influence of the rigidity. However, since the base end 62 and the liquid-absorbent core 35 are farthest apart from each other in the central portion of the crotch region 13 where body fluid is most accumulated, standing of the leak-proof cuff 60 is inhibited. No, it is possible to prevent side leakage of body fluid.

また、図５を参照すると、本実施形態においては、サイド延出部６１に位置する外側接合域４６と防漏カフ６０の基端部６２を形成する内側接合域４７とが横方向Ｘにおいて互いに離隔している。このように、外側接合域４６と基端部６２とが離隔していることによって、サイド延出部６１と防漏カフ６０とは互いの伸長、収縮作用による影響を受けることなく、独立して起立することができる。ただし、サイド延出部６１と防漏カフ６０とが互いに独立して起立する限りにおいて、おむつ１０の製造工程の簡略化のために、外側接合域４６と内側接合域４７とが連続するように被覆シート３２に塗布されていてもよい。   Referring to FIG. 5, in the present embodiment, the outer joint area 46 located in the side extension 61 and the inner joint area 47 forming the base end part 62 of the leak-proof cuff 60 are mutually in the lateral direction X. Separated. As described above, the outer joint region 46 and the base end portion 62 are separated from each other, so that the side extension portion 61 and the leak-proof cuff 60 are independently affected without being affected by the mutual expansion and contraction action. You can stand up. However, as long as the side extension part 61 and the leak-proof cuff 60 stand independently from each other, the outer joining area 46 and the inner joining area 47 are continuous in order to simplify the manufacturing process of the diaper 10. It may be applied to the covering sheet 32.
