Description

本発明は、子供用、大人用、あるいは失禁用等の使い捨て吸収性物品に関するものである。 The present invention relates to a disposable absorbent article for children, adults or incontinence.

一般的に、使い捨て吸収性物品は、表面シートと、裏面シートと、これら両シートの間に配設された吸収体とを有する略四角形状の吸収性物品本体を備えている。この吸収性物品本体には、装着者の背側の腰回りに位置する背側腰回り部と、装着者の腹側の腰回りに位置する腹側腰回り部と、装着者の股下に位置し、両側部に脚回り部を有する股下回り部とが長手方向に順次一体的に形成されている。 Generally, a disposable absorbent article includes a substantially rectangular absorbent article body having a top sheet, a back sheet, and an absorbent body disposed between the two sheets. The absorbent article main body includes a back waist portion located around the waist of the wearer, a ventral waist portion located around the waist of the wearer, and a crotch of the wearer. And the crotch part which has a leg part on both sides is integrally formed in order in the longitudinal direction.

この吸収性物品本体の前記背側腰回り部および前記腹側腰回り部の両側部には、面状ファスナを有する接合片がそれぞれ設けられ、これらの面状ファスナを係合することで前記背側腰回り部および前記腹側腰回り部の両側部が接合されて、一つの腰回り開口部と、一対の脚回り開口部とを有するパンツ形状に形成される。なお、前記背側腰回り部および前記腹側腰回り部の両側部がそれぞれ例えば溶着等によりあらかじめ接合されて、パンツ形状とされるものもある。 Bonding pieces having planar fasteners are provided on both sides of the back waist portion and the abdominal waist portion of the absorbent article body, and the back fasteners are engaged by engaging the planar fasteners. Both side portions of the side waist portion and the abdomen waist portion are joined to form a pants shape having one waist opening and a pair of leg openings. In some cases, both the back waist part and the abdomen waist part are joined in advance, for example, by welding or the like to form a pant.

そして、例えば***物等の漏出を防止する為に、吸収性物品本体の内面に長手方向に沿って、この吸収性物品本体の内面から起立可能な基部と、この基部から一体的に形成され、弾性体が設けられて伸縮可能な延出部とを有するフラップ部が設けられたものがある。 And, for example, in order to prevent leakage of excrement etc., along the longitudinal direction on the inner surface of the absorbent article main body, a base that can stand up from the inner surface of the absorbent article main body, and integrally formed from this base, There is one in which an elastic body is provided and a flap portion having an extendable and contractible extension portion is provided.

このフラップ部の延出部は、前記基部の上側に位置した中間延出部と、これら基部および中間延出部より前記吸収性物品本体の幅方向の内側に位置した内側延出部と、前記基部および前記中間延出部より前記吸収性物品本体の幅方向の外側に位置した外側延出部とから形成されており、使い捨て吸収性物品の装着時において、前記延出部が、折り重なることなく前記吸収性物品本体の幅方向へ広がり、前記延出部全体が肌に密着し易く、例えば***物等の漏出を確実に防止できる（例えば、特許文献１参照。）。
特開平１１−２７６５２０号公報（第２−４頁、図１、図３） The extension part of the flap part includes an intermediate extension part located on the upper side of the base part, an inner extension part located on the inner side in the width direction of the absorbent article body from the base part and the intermediate extension part, Formed from a base portion and an outer extension portion positioned on the outer side in the width direction of the absorbent article body from the intermediate extension portion, and when the disposable absorbent article is mounted, the extension portion does not overlap. It spreads in the width direction of the absorbent article main body, and the entire extension part is easy to adhere to the skin, and for example, leakage of excrement can be reliably prevented (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 11-276520 (page 2-4, FIGS. 1 and 3)

しかしながら上述した特許文献１の使い捨て吸収性物品では、延出部において、中間延出部は前記基部の上側に位置するので、前記基部の影響で内側延出部および外側延出部より伸縮し難くなり、延出部の幅方向の断面形状が凹状に変形してしまうので、前記延出部が装着部に確実に密着できず、例えば***物等が漏出してしまう問題が考えられる。 However, in the disposable absorbent article of Patent Document 1 described above, in the extension portion, the intermediate extension portion is located above the base portion, so that it is less likely to expand and contract than the inner extension portion and the outer extension portion due to the influence of the base portion. Thus, since the cross-sectional shape in the width direction of the extension portion is deformed into a concave shape, the extension portion cannot be securely adhered to the mounting portion, and for example, there is a problem that excrement or the like leaks out.

また、前記基部の自由部は、前記延出部の伸縮に伴って起立し易い状態になるが、前記中間延出部が前記基部の影響で伸縮し難く、前記延出部全体が伸縮し難いので、前記基部が起立し難くなり、例えば***物等の漏出を確実に防止できない問題が考えられる。 In addition, the free portion of the base portion is likely to stand up with the expansion and contraction of the extension portion, but the intermediate extension portion is difficult to expand and contract due to the influence of the base portion, and the entire extension portion is difficult to expand and contract. Therefore, it is difficult for the base to stand up, and for example, there is a problem that leakage of excrement or the like cannot be reliably prevented.

さらに、前記使い捨て吸収性物品は、インナとして別体のインナ使い捨て吸収性物品を配設して使用することがある。この場合に、特許文献１の使い捨て吸収性物品では、前記基部が起立し難く、前記内側延出部が前記外側延出部より下方に位置するように前記延出部を傾斜させた構成となっているため、前記インナ使い捨て吸収性物品を前記延出部の上部に配設し難く、前記別体の使い捨て吸収性物品を両側基部の間に配設する場合には、前記基部が使い捨て吸収性物品の幅方向の外側へ向かって起立しているため、前記基部と前記延出部によって囲むように前記別体の使い捨て吸収性物品を配設できないので、例えば***物等が漏出してしまう可能性がある。 Further, the disposable absorbent article may be used by disposing a separate inner disposable absorbent article as the inner. In this case, the disposable absorbent article of Patent Document 1 has a configuration in which the base portion is difficult to stand up and the extension portion is inclined so that the inner extension portion is positioned below the outer extension portion. Therefore, it is difficult to dispose the inner disposable absorbent article on the upper part of the extension part, and when the separate disposable absorbent article is disposed between the base parts on both sides, the base part is disposable absorbent. Since the separate disposable absorbent article cannot be disposed so as to be surrounded by the base part and the extension part because it stands up toward the outer side in the width direction of the article, for example, excrement etc. may leak out There is sex.

本発明はこのような点に鑑みなされたもので、例えば排出物等の漏出を確実に防止でき、さらに、インナ使い捨て吸収性物品を配設する場合にも確実に対応できる使い捨て吸収性物品を提供する。 The present invention has been made in view of the above points, and provides a disposable absorbent article that can reliably prevent, for example, leakage of discharged matter, and can reliably cope with an inner disposable absorbent article.

And a free portion 18 located between the base end portion 16 and the branch portion 17.

延出部15は、基部14における分岐部17の上側に位置する中間延出部19と、この中間延出部19より延出部15の幅方向の内側に位置する内側延出部20と、中間延出部19より延出部15の幅方向の外側に位置する外側延出部21とを有する。 The extending portion 15 includes an intermediate extending portion 19 positioned above the branching portion 17 in the base portion 14, and an inner extending portion 20 positioned on the inner side in the width direction of the extending portion 15 from the intermediate extending portion 19, An outer extending portion 21 located on the outer side in the width direction of the extending portion 15 from the intermediate extending portion 19 is provided.

これら基部14および延出部15をそれぞれ異なるシート材で形成すると、例えば基部14を起立し易いシート材で形成し、装着者の装着部に密着する延出部15を柔軟性が良好なシート材で形成する等、基部14および延出部15をそれぞれに適したシート材で形成できるので好ましい。 When the base 14 and the extension 15 are formed of different sheet materials, for example, the base 14 is formed of a sheet material that is easy to stand up, and the extension 15 that is in close contact with the wearer's mounting portion is a sheet material with good flexibility. For example, the base 14 and the extension 15 can be formed of sheet materials suitable for each.

基部14および延出部15を形成するシート材は限定されないが、例えば不織布や合成樹脂製シート等で形成され、表面には熱エンボスが施されている。 The sheet material forming the base portion 14 and the extension portion 15 is not limited, but is formed of, for example, a nonwoven fabric or a synthetic resin sheet, and the surface is heat embossed.

また、基部14および延出部15は、それぞれ異なる素材や製法のシート材で形成したり、同一の素材や製法のシート材で素材の密度や熱エンボスの量を変えて形成したりすることも可能である。 In addition, the base 14 and the extension 15 may be formed of sheet materials of different materials or manufacturing methods, or may be formed of sheet materials of the same material or manufacturing method with varying material density or amount of heat embossing. Is possible.

なお、この実施の形態では、異なるシート材である基部14と延出部15とが接合されてフラップ部13が形成されているが、同一のシート材で基部14と延出部15とが一体的なフラップ部13を形成してもよい。 In this embodiment, the base portion 14 and the extension portion 15 which are different sheet materials are joined to form the flap portion 13, but the base portion 14 and the extension portion 15 are integrally formed of the same sheet material. A typical flap portion 13 may be formed.

延出部15では、中間延出部19、内側延出部20、外側延出部21にそれぞれ中間弾性体22、内側弾性体23、外側弾性体24が配設されて、延出部15全体が伸縮可能となっている。 In the extending portion 15, the intermediate extending portion 19, the inner extending portion 20, and the outer extending portion 21 are provided with an intermediate elastic body 22, an inner elastic body 23, and an outer elastic body 24, respectively. Can be stretched.

中間弾性体22、内側弾性体23、外側弾性体24の収縮により延出部15全体が収縮することで、基部14は、図２に示されるような自由部18が起立する起立状態となる。また、使い捨て吸収性物品１を展開し、中間弾性体22、内側弾性体23、外側弾性体24が伸長して延出部15全体が伸長することで、基部14は、図３に示されるような内側面全体が表面シート３および吸収体５上に密着する密着状態となる。 The entire extended portion 15 contracts due to the contraction of the intermediate elastic body 22, the inner elastic body 23, and the outer elastic body 24, so that the base portion 14 is in an upright state in which the free portion 18 as shown in FIG. Further, the disposable absorbent article 1 is developed, and the intermediate elastic body 22, the inner elastic body 23, and the outer elastic body 24 are extended so that the entire extension portion 15 is extended, whereby the base portion 14 is as shown in FIG. The entire inner surface is in close contact with the top sheet 3 and the absorbent body 5.

このように、基部14は、延出部15の伸縮によって、例えば図２に示されるような起立状態や図３に示されるような密着状態等に自在に変形できる。 As described above, the base portion 14 can be freely deformed into an upright state as shown in FIG. 2, a close contact state as shown in FIG.

中間弾性体22、内側弾性体23、外側弾性体24は、例えば紐状ゴム等の伸長可能な部材であり、これら中間弾性体22、内側弾性体23、外側弾性体24が延出部15の長手方向に沿って伸長した状態で、それぞれ中間延出部19、内側延出部20、外側延出部21に例えば接着剤等で固着されて配設され、延出部15が伸縮可能となる。 The intermediate elastic body 22, the inner elastic body 23, and the outer elastic body 24 are extensible members such as string-like rubber, for example, and the intermediate elastic body 22, the inner elastic body 23, and the outer elastic body 24 are included in the extension portion 15. In an extended state along the longitudinal direction, for example, the intermediate extension portion 19, the inner extension portion 20, and the outer extension portion 21 are fixedly disposed with an adhesive or the like, for example, so that the extension portion 15 can be expanded and contracted. .

また、中間延出部19の伸長応力は、内側延出部20および外側延出部21の伸長応力より大きくなるように形成されている。 Further, the extension stress of the intermediate extension portion 19 is formed to be larger than the extension stress of the inner extension portion 20 and the outer extension portion 21.

中間弾性体22、内側弾性体23、外側弾性体24は、中間延出部19の伸長応力が内側延出部20および外側延出部21の伸長応力より大きければ、それぞれ形状は限定されず、例えば、紐状、リボン状、フィルム状等で適宜選択でき、それぞれが異なる形状のものでもよい。 The shape of the intermediate elastic body 22, the inner elastic body 23, and the outer elastic body 24 is not limited as long as the extension stress of the intermediate extension portion 19 is larger than the extension stress of the inner extension portion 20 and the outer extension portion 21, respectively. For example, a string shape, a ribbon shape, a film shape, or the like can be selected as appropriate, and each may have a different shape.

なお、中間弾性体22、内側弾性体23、外側弾性体24は、配設数や配設間隔も限定されない。 Note that the number and arrangement intervals of the intermediate elastic body 22, the inner elastic body 23, and the outer elastic body 24 are not limited.

さらに、中間弾性体22、内側弾性体23、外側弾性体24の長手方向の長さは限定されず、例えば略同一の長さの中間弾性体22、内側弾性体23、外側弾性体24が配設されてもよく、それぞれ異なる長さの中間弾性体22、内側弾性体23、外側弾性体24が配設されてもよいが、中間弾性体22および内側弾性体23の長さが外側弾性体24の長さより長いことで、延出部15の幅方向の断面形状を平面状に維持し易いので好ましい。 Further, the lengths of the intermediate elastic body 22, the inner elastic body 23, and the outer elastic body 24 in the longitudinal direction are not limited. For example, the intermediate elastic body 22, the inner elastic body 23, and the outer elastic body 24 having substantially the same length are arranged. The intermediate elastic body 22, the inner elastic body 23, and the outer elastic body 24 having different lengths may be provided, but the lengths of the intermediate elastic body 22 and the inner elastic body 23 are the outer elastic bodies. A length longer than 24 is preferable because the cross-sectional shape of the extending portion 15 in the width direction can be easily maintained flat.

また、中間延出部19の伸長応力を内側延出部20および外側延出部21の伸長応力より大きくする方法は限定されず、例えば、図２のように同一の紐状の弾性体を用いて、内側弾性体23および外側弾性体24より多い配設数の中間弾性体22を配設すると、容易に中間延出部19の伸長応力を内側延出部20および外側延出部21の伸長応力より大きくできるので好ましい。 Further, the method of making the extension stress of the intermediate extension portion 19 larger than the extension stress of the inner extension portion 20 and the outer extension portion 21 is not limited. For example, the same string-like elastic body as shown in FIG. If the number of the intermediate elastic bodies 22 is larger than that of the inner elastic body 23 and the outer elastic body 24, the extension stress of the intermediate extension portion 19 can be easily extended by the extension of the inner extension portion 20 and the outer extension portion 21. This is preferable because it can be greater than the stress.

中間弾性体22、内側弾性体23、外側弾性体24の配設方法は限定されず、図２のように、延出部15によって囲繞されるように配設されると、使い捨て吸収性物品１の装着時に、中間弾性体22、内側弾性体23、外側弾性体24によっての装着感が悪化し難いので好ましい。 The arrangement | positioning method of the intermediate | middle elastic body 22, the inner side elastic body 23, and the outer side elastic body 24 is not limited, If it arrange | positions so that it may be enclosed by the extension part 15 like FIG. 2, the disposable absorbent article 1 This is preferable because the feeling of wearing by the intermediate elastic body 22, the inner elastic body 23, and the outer elastic body 24 is unlikely to deteriorate.

なお、この場合は、延出部15の内面全面に例えば接着剤等を塗布して、内面を全面的に接合することも可能であるが、延出部15の内面を全面的に接合すると延出部15が硬くなってしまい、装着感が悪化する恐れがある。したがって、中間弾性体22、内側弾性体23、外側弾性体24それぞれに例えば接着剤等を塗布して延出部15の内面に接合し、これら中間弾性体22、内側弾性体23、外側弾性体24に塗布された接着剤によって延出部15の内面同士を接合すると、延出部15が硬くなることによる装着感の悪化を抑制できるので好ましい。 In this case, it is possible to apply, for example, an adhesive to the entire inner surface of the extension portion 15 to bond the inner surface to the entire surface. The protruding portion 15 becomes hard, and the wearing feeling may be deteriorated. Therefore, for example, an adhesive is applied to each of the intermediate elastic body 22, the inner elastic body 23, and the outer elastic body 24 and joined to the inner surface of the extending portion 15, and the intermediate elastic body 22, the inner elastic body 23, the outer elastic body, and the like. It is preferable to join the inner surfaces of the extension portions 15 with the adhesive applied to 24, since deterioration of the wearing feeling due to the extension portions 15 becoming hard can be suppressed.

フラップ部13における基部14と延出部15とがそれぞれ異なるシート材で形成された場合、必要に応じて、基部14が延出部15より不透液性の良好なシート材で形成されると、例えば***物等の漏出を効果的に防止できるので好ましい。 When the base portion 14 and the extension portion 15 in the flap portion 13 are formed of different sheet materials, if necessary, the base portion 14 is formed of a sheet material having better liquid permeability than the extension portion 15. For example, it is preferable because leakage of excrement and the like can be effectively prevented.

基部14および延出部15の両方が、不透液性を有するシート材で形成される必要はなく、基部14が不透液性を有するシート材で形成されると、この基部14が起立することで、例えば***物等の漏出を防止できるので、延出部15は不透液性を有するシート材で形成されなくてもよい。 It is not necessary that both the base portion 14 and the extension portion 15 are formed of a liquid-impermeable sheet material. When the base portion 14 is formed of a liquid-impermeable sheet material, the base portion 14 stands up. In this way, for example, leakage of excrement and the like can be prevented, so that the extension 15 does not have to be formed of a sheet material having liquid impermeability.

また、基部14および延出部15の両方が不透液性を有するシート材で形成され、さらに基部14が延出部15より不透液性が良好なシート材で形成されると、例えば***物等の漏出を確実に防止できるので好ましい。 Further, when both the base portion 14 and the extension portion 15 are formed of a sheet material having liquid impermeability, and the base portion 14 is further formed of a sheet material having better liquid permeability than the extension portion 15, for example, excretion It is preferable because leakage of objects can be surely prevented.

基部14および延出部15の不透液性については、低水圧用の耐水試験Ａ法（ＪＩＳＬ１０９２：１９９８）において、基部14のシート材の耐水度が１００ｍｍＨ_２Ｏ以上であれば、基部14の不透液性を確保できるので好ましい。さらに好ましくは１００〜４００ｍｍＨ_２Ｏである。 Regarding the liquid impermeability of the base portion 14 and the extension portion 15, in the water resistance test A method (JISL1092: 1998) for low water pressure, if the water resistance of the sheet material of the base portion 14 is 100 mmH ₂ O or more, It is preferable because liquid impermeability can be secured. More preferably 100~400mmH ₂ O.

また、延出部15のシート材は、耐水度が１００ｍｍＨ_２Ｏより小さくてもよいが、１００ｍｍＨ_２Ｏ以上であれば、延出部15の不透液性も確保できるので好ましい。 The sheet material of the extension portion 15 is water resistance may be smaller than 100 mm H ₂ O, if 100 mm H ₂ O or more, since the liquid-impermeable extension portion 15 can be ensured preferred.

なお、基部14および延出部15は、必要に応じて不透液性を有するシート材で形成されるものであり、不透液性を有するシート材で形成されない場合もある。 The base portion 14 and the extending portion 15 are formed of a liquid-impermeable sheet material as necessary, and may not be formed of a liquid-impermeable sheet material.

フラップ部13の基部14における分岐部17および自由部18より吸収性物品本体２の幅方向の外側部には、外側フラップ部25が吸収性物品本体２の長手方向に沿って形成されている。 An outer side flap portion 25 is formed along the longitudinal direction of the absorbent article main body 2 on the outer side in the width direction of the absorbent article main body 2 from the branch portion 17 and the free portion 18 in the base portion 14 of the flap portion 13.

この外側フラップ部25は、長手方向に沿って外側フラップ弾性体26が配設されて、伸縮可能となっており、このように外側フラップ弾性体26が配設された外側フラップ部25が形成されたことで、フラップ部13および外側フラップ部25によって、例えば***物等の漏出をより確実に防止でき、さらに、脚回り部９が伸縮可能となって装着者の脚回りに確実に密着できるので好ましい。 The outer flap portion 25 is provided with an outer flap elastic body 26 along the longitudinal direction and can be expanded and contracted. Thus, the outer flap portion 25 in which the outer flap elastic body 26 is provided is formed. As a result, the flap portion 13 and the outer flap portion 25 can more reliably prevent, for example, leakage of excrement and the like, and the leg portion 9 can be expanded and contracted, so that it can be securely attached to the wearer's leg. preferable.

外側フラップ弾性体26は、外側フラップ部25の長手方向に沿って配設されていれば、中間弾性体22、内側弾性体23、外側弾性体24と同様に、その形状、配設数数、配設方法、配設間隔、配設箇所は限定されないが、図２に示されるように、フラップ部13の基部14における基端部16と裏面シート４との間に外側フラップ弾性体26が配設されると、外側フラップ弾性体26による装着時の違和感を防止できるので好ましい。 If the outer flap elastic body 26 is arranged along the longitudinal direction of the outer flap portion 25, the shape, the number of arrangement, the intermediate elastic body 22, the inner elastic body 23, the outer elastic body 24, Although the arrangement method, the arrangement interval, and the arrangement location are not limited, as shown in FIG. 2, the outer flap elastic body 26 is arranged between the base end portion 16 and the back sheet 4 in the base portion 14 of the flap portion 13. If provided, it is possible to prevent a feeling of strangeness when the outer flap elastic body 26 is worn, which is preferable.

また、フラップ部13の外側延出部21の外側縁部が外側フラップ弾性体26より外側に突出していると、この突出部分から例えば***物等が漏出してしまう可能性があるので、外側延出部21の外側縁部が外側フラップ弾性体26より前記吸収性物品本体２の幅方向の内側に位置するように形成されると、例えば***物等の漏出を確実に防止できるので好ましい。 Further, if the outer edge of the outer extension 21 of the flap 13 protrudes outward from the outer flap elastic body 26, for example, excrement may leak out from the protruding portion. It is preferable that the outer edge portion of the protruding portion 21 is formed so as to be positioned on the inner side in the width direction of the absorbent article main body 2 from the outer flap elastic body 26 because leakage of excrement and the like can be reliably prevented.

さらに、フラップ部13の内側延出部20の内側縁部が吸収体５の幅方向の外側縁部より外側に位置していると、例えば***物等が延出部15を越え易くなり漏出する可能性があるので、内側延出部20の内側縁部が吸収体５上に位置するように形成されると例えば***物等の漏出をより効果的に防止できるので好ましい。 Furthermore, if the inner edge of the inner extension 20 of the flap 13 is positioned outside the outer edge of the absorbent body 5 in the width direction, for example, excrement or the like easily exceeds the extension 15 and leaks. Since there is a possibility, it is preferable to form the inner edge portion of the inner extension portion 20 so as to be positioned on the absorbent body 5 because leakage of excrement and the like can be more effectively prevented.

なお、外側フラップ部25および外側フラップ弾性体26は、必要に応じて設けるものであり、外側フラップ部25および外側フラップ弾性体26を設けない場合もある。 The outer flap portion 25 and the outer flap elastic body 26 are provided as necessary, and the outer flap portion 25 and the outer flap elastic body 26 may not be provided.

図４および図５は、使い捨て吸収性物品１にインナとして別体のインナ使い捨て吸収性物品27を配設して使用する場合を示す。 4 and 5 show a case where a separate inner disposable absorbent article 27 is disposed and used as the inner to the disposable absorbent article 1.

図４は、両側基部14間で基部14および延出部15によって囲まれるように、表面シート３および吸収体５上に別体のインナ使い捨て吸収性物品27が配設された状態である。 FIG. 4 shows a state where a separate inner disposable absorbent article 27 is disposed on the topsheet 3 and the absorbent body 5 so as to be surrounded by the base portion 14 and the extending portion 15 between the base portions 14 on both sides.

このように基部14および延出部15によって囲むように別体のインナ使い捨て吸収性物品27を配設すると、両側基部14間にインナ使い捨て吸収性物品27を固定でき、このインナ使い捨て吸収性物品27によって吸収力を向上できるとともに、基部14および延出部15によって例えば***物等の漏出を防止できるので好ましい。 When the separate inner disposable absorbent article 27 is disposed so as to be surrounded by the base portion 14 and the extension portion 15 as described above, the inner disposable absorbent article 27 can be fixed between the base portions 14 on both sides, and this inner disposable absorbent article 27 can be fixed. As a result, the absorption power can be improved, and leakage of excrement and the like can be prevented by the base portion 14 and the extension portion 15, which is preferable.

図５は、延出部15上にインナ使い捨て吸収性物品27が配設された状態であり、インナ使い捨て吸収性物品27の幅方向の長さが両側基部14間の長さより長い場合はこのように配設する。 FIG. 5 shows a state in which the inner disposable absorbent article 27 is disposed on the extension 15, and this is the case when the length of the inner disposable absorbent article 27 in the width direction is longer than the length between the side bases 14. It arranges in.

インナ使い捨て吸収性物品27を延出部15上に配設すると、基部14および延出部15によってインナ使い捨て吸収性物品27を装着部へ押し上げることができるので、インナ使い捨て吸収性物品27を直接肌に密着させることで、吸収力を向上できるので好ましい。 When the inner disposable absorbent article 27 is disposed on the extension part 15, the inner disposable absorbent article 27 can be pushed up to the mounting part by the base part 14 and the extension part 15. Since it is possible to improve the absorptive power, it is preferable to make it closely adhere to.

なお、インナ使い捨て吸収性物品27は、必要に応じて配設するものであり、特に配設しなくてもよい。 Note that the inner disposable absorbent article 27 is provided as necessary, and need not be provided.

次に、上記第１の実施の形態の作用および効果を説明する。 Next, the operation and effect of the first embodiment will be described.

使い捨て吸収性物品１の装着に際しては、吸収性物品本体２の背側腰回り部６、腹側腰回り部７、股下回り部８をそれぞれ装着者の背側腰回り、腹側腰回り、股下回りに対応させ、背側腰回り部６および腹側腰回り部７の接合片10に設けられた面状ファスナを互いに係合させて装着する。 When the disposable absorbent article 1 is worn, the back waist part 6, the abdomen waist part 7 and the crotch part 8 of the absorbent article body 2 are respectively connected to the wearer's back waist part, abdominal waist part, crotch part. Corresponding to the lower part, the planar fasteners provided on the joining piece 10 of the back side waist part 6 and the abdomen waist part 7 are engaged with each other and attached.

ここで、吸収性物品本体２の幅方向の両側部には、基部14および延出部15を有するフラップ部13が設けられたことで、装着時に、延出部15が確実に装着者の肌に密着でき、基部14と延出部15とによって例えば***物等の漏出を防止できる。 Here, since the flap part 13 which has the base 14 and the extension part 15 was provided in the both sides of the width direction of the absorbent article main body 2, the extension part 15 is surely attached to a wearer's skin at the time of mounting | wearing. The base portion 14 and the extension portion 15 can prevent leakage of excrement and the like, for example.

そして、このフラップ部13の延出部15における中間延出部19、内側延出部20、外側延出部21に、中間延出部19の伸長応力が内側延出部20および外側延出部21の伸長応力より大きくなるように、それぞれに中間弾性体22、内側弾性体23、外側弾性体24を配設することで、下側に基部14が位置し、この基部14の影響で伸縮し難い中間延出部19が、内側延出部20および外側延出部21と同様に伸縮でき、延出部15の幅方向の断面形状を平面状に維持できるので、延出部15が装着部に確実に密着でき、例えば***物等の漏出を確実に防止できる。 The extension portion 15 of the flap portion 13 has an intermediate extension portion 19, an inner extension portion 20, and an outer extension portion 21, and the extension stress of the intermediate extension portion 19 is increased by the inner extension portion 20 and the outer extension portion. By arranging the intermediate elastic body 22, the inner elastic body 23, and the outer elastic body 24 respectively so as to be larger than the elongation stress of 21, the base 14 is positioned on the lower side, and the base 14 is affected by the influence of the base 14. The difficult intermediate extension part 19 can be expanded and contracted in the same manner as the inner extension part 20 and the outer extension part 21, and the cross-sectional shape in the width direction of the extension part 15 can be maintained in a flat shape. For example, it is possible to reliably prevent leakage of excrement and the like.

また、中間延出部19が内側延出部20および外側延出部21と同様に伸縮できることで、延出部15全体が確実に伸縮でき、この延出部15の伸縮に伴って基部14が確実に起立できるので、装着者の装着部の動きに対応して延出部15が確実に装着部に密着し、例えば***物等の漏出を確実に防止できる。 Further, since the intermediate extension portion 19 can be expanded and contracted in the same manner as the inner extension portion 20 and the outer extension portion 21, the entire extension portion 15 can be expanded and contracted reliably. Since it can stand up reliably, the extension part 15 adheres to a mounting part reliably according to a motion of a mounting part of a wearer, and leakage of excrement etc. can be prevented reliably.

さらに、延出部15の幅方向の断面形状を平面状に維持できかつ基部14が確実に起立できるので、使い捨て吸収性物品１に別体のインナ使い捨て吸収性物品27を配設する場合も、インナ使い捨て吸収性物品27の幅方向の大きさに限定されることなく確実に対応できる。 Furthermore, since the cross-sectional shape of the extending portion 15 in the width direction can be maintained in a flat shape and the base portion 14 can be erected reliably, even when the separate inner disposable absorbent article 27 is disposed on the disposable absorbent article 1, The inner disposable absorbent article 27 can be reliably handled without being limited to the size in the width direction.

フラップ部13における基部14および延出部15がそれぞれ異なるシート材によって形成され、使い捨て吸収性物品１の装着時に例えば***物等と接触し易いフラップ部13の基部14が、延出部15より不透液性が良好なシート材で形成されると、例えば***物等の漏出を効果的に防止できる。 The base portion 14 and the extension portion 15 in the flap portion 13 are formed of different sheet materials, and the base portion 14 of the flap portion 13 that easily comes into contact with, for example, excrement when the disposable absorbent article 1 is attached is less than the extension portion 15. When formed with a sheet material having good liquid permeability, for example, leakage of excrement can be effectively prevented.

また、基部14および延出部15の両方が不透液性を有するシート材で形成され、さらに、基部14が延出部15より不透液性が良好なシート材で形成されると、例えば***物等の漏出を確実に防止できる。 Further, when both the base portion 14 and the extension portion 15 are formed of a sheet material having liquid impermeability, and further, when the base portion 14 is formed of a sheet material having better liquid permeability than the extension portion 15, for example, Leakage of excrement etc. can be surely prevented.

フラップ部13の基部14における分岐部17および自由部18より吸収性物品本体２の幅方向の外側部に、吸収性物品本体２の長手方向に沿って、外側フラップ弾性体26が配設された伸縮可能な外側フラップ部25が設けられたことで、フラップ部13と外側フラップ部25とによって、例えば***物等の漏出をより確実に防止できる。 An outer flap elastic body 26 is disposed along the longitudinal direction of the absorbent article main body 2 on the outer side in the width direction of the absorbent article main body 2 from the branch portion 17 and the free portion 18 in the base portion 14 of the flap portion 13. By providing the outer flap portion 25 that can be expanded and contracted, the flap portion 13 and the outer flap portion 25 can more reliably prevent leakage of excrement, for example.

また、フラップ部13の外側延出部21の外側縁部が、外側フラップ弾性体26より吸収性物品本体２の幅方向の内側に位置し、フラップ部13の内側延出部20の内側縁部が吸収体５上に位置するように形成されることで、フラップ部13と外側フラップ部25とによって例えば***物等の漏出をより確実に防止できる。 Further, the outer edge of the outer extension 21 of the flap 13 is positioned on the inner side in the width direction of the absorbent article body 2 from the outer flap elastic body 26, and the inner edge of the inner extension 20 of the flap 13. Is formed so as to be positioned on the absorbent body 5, for example, leakage of excrement and the like can be more reliably prevented by the flap portion 13 and the outer flap portion 25.

次に、第２の実施の形態を図６を参照して説明する。なお、上記の実施の形態と同一の構成および作用については、同一符号を付してその説明を省略する。 Next, a second embodiment will be described with reference to FIG. In addition, about the structure and effect | action same as said embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

図６に示されるように、中間延出部19に中間弾性体22が三本配設され、内側延出部20に中間弾性体22と同一の弾性体である内側弾性体23が中間弾性体22より広い配設間隔で二本配設され、外側延出部21に中間弾性体22および内側弾性体23と同一の弾性体である外側弾性体24が一本配設されている。 As shown in FIG. 6, three intermediate elastic bodies 22 are arranged in the intermediate extension portion 19, and an inner elastic body 23 that is the same elastic body as the intermediate elastic body 22 is provided in the inner extension portion 20. Two outer elastic bodies 24 that are the same elastic bodies as the intermediate elastic body 22 and the inner elastic body 23 are provided in the outer extending portion 21 at two arrangement intervals wider than 22.

このように中間弾性体22、内側弾性体23、外側弾性体24を配設することで、フラップ部13の延出部15では、中間延出部19の伸長応力が最も大きく、次いで内側延出部20の伸長応力が大きく、外側延出部21の伸長応力が最も小さくなる。 By arranging the intermediate elastic body 22, the inner elastic body 23, and the outer elastic body 24 in this way, the extension portion 15 of the flap portion 13 has the largest extension stress of the intermediate extension portion 19, and then the inner extension The extension stress of the portion 20 is large, and the extension stress of the outer extension portion 21 is the smallest.

最も伸縮し難い中間延出部19の伸長応力を最も大きくし、次いで伸縮し難い内側延出部20の伸長応力を次いで大きくし、最も伸縮し易い外側延出部21の伸長応力を最も小さくすることで、延出部15の幅方向の断面形状をより確実に平面状に維持でき、延出部15が装着部に確実に密着できるので、例えば***物の漏出を確実に防止できる。 The extension stress of the intermediate extension part 19 that is most difficult to expand and contract is maximized, the extension stress of the inner extension part 20 that is difficult to expand and contract is then increased, and the extension stress of the outer extension part 21 that is most easily expanded and contracted is minimized. Thus, the cross-sectional shape of the extending portion 15 in the width direction can be more reliably maintained in a flat shape, and the extending portion 15 can be securely adhered to the mounting portion, so that, for example, leakage of excrement can be reliably prevented.

延出部15において伸長応力を調整する方法は上述した方法に限定されず、例えばそれぞれ異なる弾性体を配設して調整する方法や同一の弾性体を用いて弾性体の配設数や配設間隔を変えて調整する方法等で適宜選択できる。 The method of adjusting the extension stress in the extending portion 15 is not limited to the above-described method. For example, a method of adjusting by arranging different elastic bodies, the number of elastic bodies arranged using the same elastic body, and the arrangement thereof It can select suitably by the method etc. which adjust by changing a space | interval.

次に、第３の実施の形態を図７を参照して説明する。なお、上記の実施の形態と同一の構成および作用については、同一符号を付してその説明を省略する。 Next, a third embodiment will be described with reference to FIG. In addition, about the structure and effect | action same as said embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

図７に示されるように、フラップ部13の延出部15は、内側延出部20の幅方向の長さが、外側延出部21の幅方向の長さより短く形成されている。 As shown in FIG. 7, the extending portion 15 of the flap portion 13 is formed such that the length in the width direction of the inner extending portion 20 is shorter than the length in the width direction of the outer extending portion 21.

なお、内側延出部20および外側延出部21の幅方向の長さは限定されないが、外側延出部21の幅方向の長さを自由部18の断面方向の長さより短くすると、自由部18が起立し易いので好ましい。 Although the length in the width direction of the inner extension portion 20 and the outer extension portion 21 is not limited, if the length in the width direction of the outer extension portion 21 is shorter than the length in the cross-sectional direction of the free portion 18, the free portion 18 is preferable because it is easy to stand up.

このように、内側延出部20の幅方向の長さが、外側延出部21の幅方向の長さより短く形成されたことで、吸収体５上に位置する表面シート３および吸収体５が内側延出部20によって覆われる面積を小さくできるので、内側延出部20による吸収体５の吸収力の低下を抑制できる。 As described above, the length of the inner extension portion 20 in the width direction is shorter than the length of the outer extension portion 21 in the width direction, so that the topsheet 3 and the absorber 5 positioned on the absorber 5 are Since the area covered by the inner extension portion 20 can be reduced, it is possible to suppress a decrease in the absorption power of the absorbent body 5 by the inner extension portion 20.

また、外側延出部21の幅方向の長さが長いので、幅方向の長さが長いインナ使い捨て吸収性物品27であっても延出部15上に確実に配設できる。 Further, since the length in the width direction of the outer extending portion 21 is long, even the inner disposable absorbent article 27 having a long length in the width direction can be reliably disposed on the extending portion 15.

次に、第４の実施の形態を図８を参照して説明する。なお、上記の実施の形態と同一の構成および作用については、同一符号を付してその説明を省略する。 Next, a fourth embodiment will be described with reference to FIG. In addition, about the structure and effect | action same as said embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

図８に示されるように、フラップ部13の長手方向の両端縁部には、内側延出部20の下側面と表面シート３の上側面とが接合された内側接合部30が形成され、さらに外側延出部21の下側面と基部14の外側面とが接合された外側接合部31が形成されている。 As shown in FIG. 8, an inner joint portion 30 in which the lower side surface of the inner extension portion 20 and the upper side surface of the topsheet 3 are joined is formed at both end edges in the longitudinal direction of the flap portion 13. An outer joint portion 31 is formed in which the lower surface of the outer extension portion 21 and the outer surface of the base portion 14 are joined.

また、外側接合部31の長手方向の長さは、内側接合部30の長手方向の長さより長く形成されており、このように形成されることで、内側延出部20より反りが発生し易い外側延出部21の反りの発生を抑制でき、延出部15全体を平面状に維持し易くできるので、確実に延出部15が肌に密着でき、例えば***物等の漏出を確実に防止できる。 Further, the length in the longitudinal direction of the outer joint portion 31 is formed to be longer than the length in the longitudinal direction of the inner joint portion 30, and the warpage is more likely to occur than the inner extension portion 20 by being formed in this way. The occurrence of warpage of the outer extension 21 can be suppressed, and the extension 15 can be easily maintained flat, so that the extension 15 can be in close contact with the skin, and for example, leakage of excrement etc. can be reliably prevented. it can.

そして、吸収性物品本体２の長手方向の両端縁部の吸収体５が配設されていない部分には、内側接合部30と外側接合部31とによって端縁フラップ部32が形成され、例えば***物等が吸収性物品本体２の長手方向から漏出する恐れを防止できる。 And the edge flap part 32 is formed in the part in which the absorber 5 of the both ends edge part of the longitudinal direction of the absorbent article main body 2 is not arrange | positioned by the inner side junction part 30 and the outer side junction part 31, for example, excretion It is possible to prevent the possibility that objects etc. leak from the longitudinal direction of the absorbent article body 2.

ここで、内側接合部30は、吸収体５が配設されていない端縁フラップ部32上に形成され、外側接合部31は、端縁フラップ部32から吸収体５が配設された部分の中間弾性体22、内側弾性体23、外側弾性体24の近傍まで形成されると、端縁フラップ部32によって例えば***物等の漏出をより確実に防止でき、外側延出部21の反りの発生をより抑制できるので好ましい。 Here, the inner joint portion 30 is formed on the edge flap portion 32 where the absorber 5 is not disposed, and the outer joint portion 31 is a portion of the portion where the absorber 5 is disposed from the edge flap portion 32. When formed up to the vicinity of the intermediate elastic body 22, the inner elastic body 23, and the outer elastic body 24, leakage of excrement etc. can be prevented more reliably by the edge flap portion 32, and warpage of the outer extension portion 21 occurs. Is more preferable because it can be further suppressed.

次に、第５の実施の形態を図９を参照して説明する。なお、上記の実施の形態と同一の構成および作用については、同一符号を付してその説明を省略する。 Next, a fifth embodiment will be described with reference to FIG. In addition, about the structure and effect | action same as said embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

パンツ形状にして着用されるタイプの使い捨て吸収性物品１において、図９に示されるように、フラップ部13の延出部15は、吸収性物品本体２の背側腰回り部６の少なくとも一部に設けられた非伸縮である背側非伸縮部33と、吸収性物品本体２の腹側腰回り部７の少なくとも一部に設けられた非伸縮である腹側非伸縮部34とを備えており、背側非伸縮部33の吸収性物品本体２の長手方向の長さは、腹側非伸縮部34の吸収性物品本体２の長手方向の長さより長く形成されている。 In the disposable absorbent article 1 of the type worn in pants, as shown in FIG. 9, the extension part 15 of the flap part 13 is at least part of the back waist part 6 of the absorbent article body 2. A non-stretchable dorsal side non-stretchable portion 33 and a non-stretchable ventral side non-stretchable portion 34 provided on at least a part of the abdomen waistline portion 7 of the absorbent article body 2. The longitudinal length of the absorbent article main body 2 of the back side non-stretchable portion 33 is formed longer than the length of the abdominal non-stretchable portion 34 in the longitudinal direction of the absorbent article main body 2.

これら背側非伸縮部33および腹側非伸縮部34を非伸縮に形成する方法は限定されず、例えば弾性体を配設しない方法や配設された弾性体を切断する方法等で適宜選択できる。 The method of forming the dorsal non-stretchable portion 33 and the ventral non-stretchable portion 34 in a non-stretchable manner is not limited. .

ここで、装着者の背側の腰回りは腹側の腰回りに比べて屈曲し難く、背側腰回り部６は比較的伸縮性を有さなくてよいので、背側非伸縮部33の長さを腹側非伸縮部34の長さより長く形成し、背側腰回り部６を腹側腰回り部７より伸縮し難くすることで、背側腰回り部６および腹側腰回り部７を装着者の腰回りに対応させ易くできるので、使い捨て吸収性物品１を容易に装着できる。 Here, the waistline on the back side of the wearer is less likely to bend than the waistline on the abdomen side, and the back side waistline part 6 does not have to be relatively stretchable. By forming the length longer than the length of the ventral side non-stretchable portion 34 and making the back side waistline portion 6 less stretchable than the ventral side waistline portion 7, the back side waistline portion 6 and the ventral side waistline portion 7. Can be easily adapted to the waist circumference of the wearer, so that the disposable absorbent article 1 can be easily worn.

また、背側非伸縮部33の長手方向の長さを比較的長めに形成することで、中間弾性体22、内側弾性体23、外側弾性体24の伸縮によって、背側腰回り部６に皺が形成され難くできるので、皺による装着時の違和感を抑制できる。 Further, by forming the length of the back side non-stretchable portion 33 in the longitudinal direction to be relatively long, the back side waistline portion 6 can be stretched by the expansion and contraction of the intermediate elastic body 22, the inner elastic body 23, and the outer elastic body 24. Since it is difficult to form, it is possible to suppress a sense of incongruity when worn by a heel.

背側非伸縮部33の吸収性物品本体２の長手方向の長さが、腹側非伸縮部34の吸収性物品本体２の長手方向の長さより長く形成されていれば、これら背側非伸縮部33および腹側非伸縮部34の長さは限定されず、例えば背側腰回り部６全体の延出部15を背側非伸縮部33とすると、背側腰回り部６に皺ができ難く、装着時の違和感をより抑制できるので好ましい。 If the length in the longitudinal direction of the absorbent article main body 2 of the back side non-stretchable part 33 is formed longer than the length of the absorbent article main body 2 in the longitudinal direction of the ventral side non-stretchable part 34, these back side non-stretchable parts The lengths of the portion 33 and the ventral non-stretchable portion 34 are not limited. For example, if the extended portion 15 of the entire back waistline portion 6 is the backside non-stretchable portion 33, the backside waistline portion 6 can be wrinkled. It is difficult, and it is preferable because it can suppress a sense of incongruity at the time of wearing.

次に、第６の実施の形態を図１０を参照して説明する。なお、上記の実施の形態と同一の構成および作用については、同一符号を付してその説明を省略する。 Next, a sixth embodiment will be described with reference to FIG.
