Description

本発明は、着用者からの***物を受ける吸収性物品に関する。   The present invention relates to an absorbent article that receives excrement from a wearer.

従来より、使い捨ておむつや下着に取り付けて使用される軽失禁用の吸収パッド等の吸収性物品では、幅方向の両側において着用者に向かって起立する一対の側壁部（いわゆる、立体ギャザー）が設けられており、これにより、尿等の***物の漏出防止が図られている。   Conventionally, absorbent articles such as light incontinence absorbent pads used by attaching to disposable diapers and underwear are provided with a pair of side walls (so-called three-dimensional gathers) that stand toward the wearer on both sides in the width direction. Thus, leakage of excrement such as urine is prevented.

例えば、特許文献１の吸収性物品では、幅方向の両側に設けられた防漏壁が、着用者に向かって起立する基壁部、および、基壁部の上端部に連設された面状の弾性伸縮部を備え、面状の弾性伸縮部を着用者の肌に平面的にフィットさせることにより尿等の漏れ防止が図られている。特許文献１の吸収性物品では、面状の弾性伸縮部の幅方向の両端、および、その間の部位に長手方向に伸びる複数の弾性糸が接合されている。   For example, in the absorbent article of Patent Document 1, the leak-proof walls provided on both sides in the width direction are a base wall portion that stands up toward the wearer, and a planar shape that is connected to the upper end portion of the base wall portion. In order to prevent leakage of urine and the like, the elastic elastic part is provided to fit the wearer's skin planarly. In the absorbent article of Patent Document 1, a plurality of elastic yarns extending in the longitudinal direction are joined to both ends in the width direction of the planar elastic stretchable part and a portion therebetween.

また、特許文献２の吸収性物品では、２層の防液性シートを積層して形成されたバリヤカフスにおいて、２層の防液性シートを長手方向に伸びる線状の接合部にて接合することにより、２層の防液性シートの間に長手方向に伸びる複数の中空部が形成され、これらの中空部に弾性糸が防液性シートに接合されることなく配置される。   Moreover, in the absorbent article of patent document 2, in the barrier cuff formed by laminating two layers of liquid-proof sheets, the two layers of liquid-proof sheets are joined at a linear joint extending in the longitudinal direction. Thus, a plurality of hollow portions extending in the longitudinal direction are formed between the two layers of liquid-proof sheets, and elastic yarns are arranged in these hollow portions without being bonded to the liquid-proof sheets.

特許文献３の吸収性物品では、トップシートの幅方向の中央部と両側部とが長手方向の全長に亘ってベース層（吸収コア）またはバックシートに接合され、当該中央部と両側部との間の非接着領域においてトップシートとベース層との間に長手方向に伸びる弾性糸が配置される。弾性糸は、両端部においてトップシートおよびベース層に接着され、両端部の間の部位は非接着部分とされる。特許文献３の吸収性物品では、弾性糸が収縮することによりトップシートの非接着領域がベース層から離間して立ち上がり、フローティング内側カフスが形成される。   In the absorbent article of patent document 3, the center part and both side part of the width direction of a top sheet are joined to a base layer (absorption core) or a back sheet over the full length of a longitudinal direction, The said center part and both side parts An elastic yarn extending in the longitudinal direction is disposed between the top sheet and the base layer in the non-bonded region therebetween. The elastic yarn is bonded to the top sheet and the base layer at both ends, and a portion between the both ends is a non-bonded portion. In the absorbent article of Patent Document 3, when the elastic yarn contracts, the non-adhesion region of the top sheet rises away from the base layer, and a floating inner cuff is formed.

一方、特許文献４の使い捨ておむつでは、股下部の左右両側においてトップシートとバックシートとの間に形成された３本の管状部に弾性糸がそれぞれ接着等されることなく挿入されており、これらの弾性糸が収縮することによりレッグギャザーが形成される。
特許第３９１９６３８号公報 国際公開第ＷＯ９５／０７０６３号パンフレット 特許第２９４１２９０号公報 特許第３４７９３８３号公報 On the other hand, in the disposable diaper of Patent Document 4, elastic yarns are inserted into the three tubular parts formed between the top sheet and the back sheet on both the left and right sides of the crotch without being bonded to each other. Leg gathers are formed by contraction of the elastic yarn.

図１は、本発明の一の実施の形態に係る吸収性物品１を示す平面図であり、吸収性物品１は、着用者が着用する外装物品である下着の着用者側に取り付けられて着用者からの尿等の***物を受ける軽失禁用の吸収パッドである。吸収性物品１は、パッケージ等における表示吸収量が約２００ｍｌ（ミリリットル）以下である吸収パッドであり、本実施の形態では、吸収性物品１の表示吸収量は２０ｍｌ以上４０ｍｌ以下とされる。ただし、吸収性物品１の実際の吸収量は表示吸収量よりも大きい。図１では、着用者に接する面（すなわち、着用者側）を手前側にして吸収性物品１を描いている。   FIG. 1 is a plan view showing an absorbent article 1 according to an embodiment of the present invention, and the absorbent article 1 is attached to a wearer side of an undergarment that is an exterior article worn by the wearer. It is an absorption pad for light incontinence that receives excrement such as urine from a person. The absorbent article 1 is an absorbent pad having a display absorption amount of about 200 ml (milliliter) or less in a package or the like. In the present embodiment, the display absorption amount of the absorbent article 1 is 20 ml or more and 40 ml or less. However, the actual absorption amount of the absorbent article 1 is larger than the display absorption amount. In FIG. 1, the absorbent article 1 is drawn with the surface in contact with the wearer (that is, the wearer side) facing forward.

図２は、吸収性物品１を図１中に示すＡ−Ａの位置にて吸収性物品１の長手方向（すなわち、図１中の上下方向）に垂直な面で切断した断面図であり、図３は、吸収性物品１の図１中における上側の端部近傍の部位をＢ−Ｂの位置にて長手方向に垂直な面で切断した断面図である。吸収性物品１では、図１中における下側の端部近傍の部位も、図３に示す断面と同様の構造を有する。   FIG. 2 is a cross-sectional view of the absorbent article 1 cut along a plane perpendicular to the longitudinal direction of the absorbent article 1 (ie, the vertical direction in FIG. 1) at the position AA shown in FIG. FIG. 3 is a cross-sectional view of the absorbent article 1 taken along a plane perpendicular to the longitudinal direction at a position BB in the vicinity of the upper end in FIG. In the absorbent article 1, the site | part of the lower edge part vicinity in FIG. 1 also has the structure similar to the cross section shown in FIG.

図１および図２に示すように、吸収性物品１は、バックシート２３、制臭シート２４、吸収コア２２およびトップシート２１が着用者側とは反対側から順に積層された略シート状の本体部２、並びに、本体部２の両側部上において（すなわち、長手方向に垂直な幅方向の両側において）本体部２の長手方向のほぼ全長に亘って設けられた一対のサイドシート３を備える。本体部２では、トップシート２１とバックシート２３との間に配置された吸収体である吸収コア２２の着用者側の主面がトップシート２１により覆われ、吸収コア２２の着用者側とは反対側の主面がバックシート２３により覆われる。トップシート２１およびバックシート２３は、ホットメルト接着剤等により吸収コア２２および制臭シート２４の周囲にて互いに接合される。図２では、図示の都合上、本体部２の各構成およびサイドシート３を分離して描いている（図３、並びに、図５ないし図７においても同様）。   As shown in FIG. 1 and FIG. 2, the absorbent article 1 is a substantially sheet-like main body in which a back sheet 23, an odor control sheet 24, an absorbent core 22 and a top sheet 21 are laminated in order from the side opposite to the wearer side. And a pair of side sheets 3 provided over substantially the entire length in the longitudinal direction of the main body 2 on both sides of the main body 2 (that is, on both sides in the width direction perpendicular to the longitudinal direction). In the main body 2, the wearer-side main surface of the absorbent core 22, which is an absorbent body disposed between the topsheet 21 and the backsheet 23, is covered by the topsheet 21. The opposite main surface is covered with the back sheet 23. The top sheet 21 and the back sheet 23 are joined to each other around the absorbent core 22 and the odor control sheet 24 by a hot melt adhesive or the like. In FIG. 2, for convenience of illustration, each configuration of the main body 2 and the side sheet 3 are drawn separately (the same applies to FIGS. 3 and 5 to 7).

トップシート２１は透液性のシート材料、例えば、親水性繊維により形成された不織布であり、着用者からの***物の水分を速やかに捕捉して吸収コア２２へと移動させる。トップシート２１として利用される不織布は、例えば、ポイントボンド不織布やエアスルー不織布、スパンレース不織布であり、これらの不織布を形成する親水性繊維としては通常、セルロースやレーヨン、コットン等が用いられる。なお、トップシート２１として、表面を界面活性剤により親水処理した疎水性繊維（例えば、ポリプロピレン、ポリエチレン、ポリエステル、ポリアミド、ナイロン）にて形成された透液性の不織布が利用されてもよく、また、開孔を有するプラスチックフィルムが利用されてもよい。   The top sheet 21 is a liquid-permeable sheet material, for example, a non-woven fabric formed of hydrophilic fibers, and quickly captures moisture of excrement from the wearer and moves it to the absorbent core 22. Nonwoven fabrics used as the top sheet 21 are, for example, point bond nonwoven fabrics, air-through nonwoven fabrics, and spunlace nonwoven fabrics. As hydrophilic fibers forming these nonwoven fabrics, cellulose, rayon, cotton, or the like is usually used. As the top sheet 21, a liquid-permeable nonwoven fabric formed of hydrophobic fibers (for example, polypropylene, polyethylene, polyester, polyamide, nylon) whose surface is hydrophilically treated with a surfactant may be used. Alternatively, a plastic film having an aperture may be used.

吸収コア２２は、厚さ方向に積層された２層のコア部材２２１，２２２を備える。コア部材２２１，２２２はそれぞれ、親水性繊維（例えば、粉砕したパルプ繊維やセルロース繊維）に粒状の吸水性ポリマー（例えば、ＳＡＰ（Super Absorbent Polymer））を混合したものをティッシュペーパーや透液性不織布等の被覆シートにより包み込んで形成され、トップシート２１を透過した水分を吸収して迅速に固定する。親水性繊維を包む被覆シートは、親水性繊維および吸水性ポリマーとホットメルト接着剤により接合されて、親水性繊維の型崩れ、および、吸水性ポリマーの脱落（特に、吸水後における脱落）を防止する。   The absorbent core 22 includes two layers of core members 221 and 222 stacked in the thickness direction. Each of the core members 221 and 222 is obtained by mixing a hydrophilic fiber (for example, pulverized pulp fiber or cellulose fiber) with a granular water-absorbing polymer (for example, SAP (Super Absorbent Polymer)). It is formed by wrapping with a covering sheet such as the like, and absorbs moisture that has passed through the top sheet 21 and quickly fixes it. The cover sheet that wraps the hydrophilic fiber is bonded to the hydrophilic fiber and the water-absorbing polymer with a hot-melt adhesive to prevent the hydrophilic fiber from losing its shape and the water-absorbing polymer from falling off (especially after water absorption). To do.

なお、コア部材２２１，２２２の構造は、上記構造には限定されず、各コア部材は、例えば、２枚の不織布の間に粒状の高吸水性ポリマーをホットメルト接着剤等により固定した上で当該２枚の不織布をホットメルト接着剤やヒートシール等により接合した構造とされてもよい。このような構造のコア部材では、高吸水性ポリマーは、それぞれが長手方向に連続的に伸びる帯状であって幅方向に配列された複数の領域に固定され、当該複数の領域の隙間（すなわち、高吸水性ポリマーの非存在領域）において２枚の不織布がヒートシール等により接合されることにより、高吸水性ポリマーの複数の存在領域が個別に封止されることが好ましい。また、吸収コア２２は、例えば、１つのコア部材により構成されてもよい。   In addition, the structure of the core members 221 and 222 is not limited to the above structure, and each core member is formed by, for example, fixing a granular superabsorbent polymer between two nonwoven fabrics with a hot melt adhesive or the like. The two nonwoven fabrics may be joined by a hot melt adhesive or heat seal. In the core member having such a structure, the superabsorbent polymer is fixed to a plurality of regions each having a strip shape continuously extending in the longitudinal direction and arranged in the width direction, and gaps between the plurality of regions (that is, In the non-existing region of the superabsorbent polymer), it is preferable that the two non-woven fabrics are joined by heat sealing or the like so that the plural superabsorbing polymer regions are individually sealed. Moreover, the absorption core 22 may be comprised by one core member, for example.

バックシート２３は、撥水性または不透液性のプラスチックフィルムであり、トップシート２１を透過した***物が、本体部２の外部へとしみ出すことを防止する。吸収性物品１のムレを防止して着用者の快適性を向上するという観点からは、透湿性（すなわち、通気性）を有するプラスチックフィルムがバックシート２３として利用されることが好ましい。バックシート２３としては、撥水性または不透液性の不織布（例えば、スパンボンド不織布やメルトブロー不織布、ＳＭＳ不織布）や当該不織布の着用者側に撥水性または不透液性のプラスチックフィルムが積層された積層シートが利用されてもよい。   The back sheet 23 is a water-repellent or liquid-impervious plastic film, and prevents excrement that has permeated through the top sheet 21 from seeping out of the main body 2. From the viewpoint of preventing wear of the absorbent article 1 and improving the comfort of the wearer, it is preferable that a plastic film having moisture permeability (that is, air permeability) is used as the back sheet 23. As the back sheet 23, a water-repellent or liquid-impervious nonwoven fabric (for example, a spunbond nonwoven fabric, a melt blown nonwoven fabric, an SMS nonwoven fabric) or a water-repellent or liquid-impervious plastic film is laminated on the wearer side of the nonwoven fabric. Laminated sheets may be used.

制臭シート２４は、制臭剤を含有する親水性のシート部材であり、制臭シート２４を形成する親水性繊維としては、例えば、セルロースやパルプが用いられる。制臭剤としては、好ましくは金属（例えば、銀、銅、亜鉛、鉄、ニッケルコバルト、パラジウム、白金）を担持するゼオライト等の無機多孔結晶が用いられる。   The odor control sheet 24 is a hydrophilic sheet member containing an odor control agent, and as the hydrophilic fiber forming the odor control sheet 24, for example, cellulose or pulp is used. As the deodorant, an inorganic porous crystal such as a zeolite carrying a metal (for example, silver, copper, zinc, iron, nickel cobalt, palladium, platinum) is preferably used.

一対のサイドシート３はそれぞれ、図１および図２に示すように、撥水性または不透液性のシート部材であるサイドシート本体３１に、長手方向に伸びる帯状の弾性部材３２が部分的に接合されることにより形成される。本実施の形態では、サイドシート本体３１には弾性部材３２以外の弾性部材は接合されない。サイドシート本体３１は、例えば、スパンボンド不織布、メルトブロー不織布、ＳＭＳ不織布、または、エアスルー不織布により形成される。また、サイドシート本体３１は、プラスチックフィルムや上記不織布とプラスチックフィルムとが積層された積層シートにより形成されてもよく、この場合、透湿性を有するプラスチックフィルムが利用されることにより、吸収性物品１のムレが防止されて着用者の快適性が向上される。   As shown in FIGS. 1 and 2, each of the pair of side sheets 3 is partially joined to a side sheet main body 31 that is a water-repellent or liquid-impervious sheet member by a belt-like elastic member 32 extending in the longitudinal direction. Is formed. In the present embodiment, no elastic member other than the elastic member 32 is joined to the side seat body 31. The side sheet body 31 is formed of, for example, a spunbond nonwoven fabric, a melt blown nonwoven fabric, an SMS nonwoven fabric, or an air-through nonwoven fabric. The side sheet main body 31 may be formed of a plastic film or a laminated sheet in which the nonwoven fabric and the plastic film are laminated. In this case, the absorbent article 1 is obtained by using a plastic film having moisture permeability. This prevents stuffiness and improves the wearer's comfort.

図４は、図２中の弾性部材３２を拡大して示す断面図である。図４に示すように、弾性部材３２は、不織布により形成される２枚の帯状部材３２１，３２２、および、長手方向に伸びる２本の弾性糸３２３を備える。２枚の帯状部材３２１，３２２は、長手方向に伸びるとともに重ねられてホットメルト接着剤等により互いに接合される。２本の弾性糸３２３は、２枚の帯状部材３２１，３２２の間において、長手方向に沿って略平行かつ間隔をあけて配置され、伸張状態にて２枚の帯状部材３２１，３２２に接合される。弾性糸３２３としては、ポリウレタン糸や糸状の天然ゴム等が用いられる。本実施の形態では、弾性部材３２の幅は、５ｍｍ以上７０ｍｍ以下（より好ましくは、８ｍｍ以上６５ｍｍ以下）とされる。   FIG. 4 is an enlarged cross-sectional view of the elastic member 32 in FIG. As shown in FIG. 4, the elastic member 32 includes two belt-like members 321 and 322 formed of a nonwoven fabric, and two elastic yarns 323 extending in the longitudinal direction. The two strip members 321 and 322 extend in the longitudinal direction and are overlapped and joined to each other by a hot melt adhesive or the like. The two elastic yarns 323 are arranged between the two belt-like members 321 and 322 in a substantially parallel and spaced manner along the longitudinal direction, and are joined to the two belt-like members 321 and 322 in an extended state. The As the elastic yarn 323, polyurethane yarn, thread-like natural rubber, or the like is used. In the present embodiment, the width of the elastic member 32 is 5 mm to 70 mm (more preferably, 8 mm to 65 mm).

なお、弾性部材３２は、必ずしも２枚の帯状部材３２１，３２２により形成される必要はなく、例えば、１枚の帯状の布状部材が長手方向に伸びる折り返し線にて２つ折りにされて重ねられ、折り返し線の両側の２つの帯状部が、間に複数の弾性糸３２３を挟んで接合されることにより弾性部材３２が形成されてもよい。また、２枚の帯状部材３２１，３２２は、布状の部材により形成されるのであれば、必ずしも不織布により形成される必要はない。   The elastic member 32 is not necessarily formed by the two belt-like members 321 and 322. For example, one belt-like cloth-like member is folded in two along a folding line extending in the longitudinal direction and overlapped. The elastic member 32 may be formed by joining two belt-like portions on both sides of the folding line with a plurality of elastic yarns 323 interposed therebetween. Further, the two strip-shaped members 321 and 322 are not necessarily formed of a non-woven fabric as long as they are formed of a cloth-shaped member.

図２および図３に示すように、一対のサイドシート３はそれぞれ、長手方向の全長に亘って設けられた折り曲げ線３９の一方側の部位である帯状の接合部３３、および、折り曲げ線３９の他方側の部位である側壁部３４を備える。接合部３３は、本体部２の側方エッジ近傍において長手方向の全長に亘って本体部２の着用者側にホットメルト接着剤を介して接合され、側壁部３４は、折り曲げ線３９にて着用者側へと折り曲げられるとともにその一部（後述する起立部３４２（図２参照））が本体部２から起立する。   As shown in FIGS. 2 and 3, the pair of side sheets 3 are each formed of a belt-like joint portion 33 that is a part of one side of the fold line 39 provided over the entire length in the longitudinal direction, and the fold line 39. The side wall part 34 which is a site | part of the other side is provided. The joining portion 33 is joined to the wearer side of the main body portion 2 over the entire length in the vicinity of the side edge of the main body portion 2 via a hot melt adhesive, and the side wall portion 34 is worn at a fold line 39. A part thereof (an upright part 342 (see FIG. 2) described later) stands up from the main body part 2 while being bent toward the person side.

側壁部３４は、図３に示すように、長手方向の両端部において接合部３３上に重ねられてヒートシールにより接合部３３上に固定される２つの固定部３４１を備える。図１では、図の理解を容易にするために、一対の側壁部３４の各固定部３４１に平行斜線を付している。なお、固定部３４１の接合部３３に対する固定は、超音波接合やホットメルト接着剤による接着、あるいは、ヒートシールとホットメルト接着剤による接着の組み合わせ等により行われてもよい。   As shown in FIG. 3, the side wall portion 34 includes two fixing portions 341 that are overlapped on the joint portion 33 at both ends in the longitudinal direction and fixed on the joint portion 33 by heat sealing. In FIG. 1, in order to facilitate understanding of the drawing, parallel diagonal lines are given to the fixing portions 341 of the pair of side wall portions 34. The fixing portion 341 may be fixed to the bonding portion 33 by ultrasonic bonding, adhesion with a hot melt adhesive, or a combination of heat sealing and adhesion with a hot melt adhesive.

側壁部３４は、また、図２に示すように、本体部２の側方エッジよりも内側に位置する折り曲げ線３９から（すなわち、本体部２の側方エッジから内側に離れた本体部２上の位置から）着用者側へと起立する起立部３４２、および、起立部３４２の上端（すなわち、着用者側の端部）から幅方向における外方へと広がる平面部３４３を備える。本実施の形態では、起立部３４２の高さが数ｍｍ程度と極めて小さくされるが、側壁部３４では、もっと高い起立部３４２が設けられてもよい。   As shown in FIG. 2, the side wall 34 is also separated from a fold line 39 located inside the side edge of the main body 2 (that is, on the main body 2 away from the side edge of the main body 2. And a flat portion 343 extending from the upper end of the standing portion 342 (ie, the end portion on the wearer side) outward in the width direction. In the present embodiment, the height of the upright portion 342 is extremely small, such as several millimeters, but the side wall portion 34 may be provided with a higher upright portion 342.

平面部３４３は、２つのシート部（以下、図２中の上側および下側のシート部をそれぞれ、「第１平面シート部３４３１」および「第２平面シート部３４３２」という。）が積層されることにより形成されており、第１平面シート部３４３１と第２平面シート部３４３２とは長手方向の全長に亘って非接合とされる。側壁部３４では、弾性部材３２が、第１平面シート部３４３１と第２平面シート部３４３２との間において平面部３４３の外エッジ３４３３（すなわち、幅方向の外側のエッジ）から離れた位置に平面部３４３の全長に亘って配置される。平面部３４３および起立部３４２は、図１に示すように、２つの固定部３４１の間において２つの固定部３４１から連続している。   The planar portion 343 includes two sheet portions (hereinafter, the upper and lower sheet portions in FIG. 2 are referred to as “first planar sheet portion 3431” and “second planar sheet portion 3432”, respectively). Thus, the first flat sheet portion 3431 and the second flat sheet portion 3432 are not joined over the entire length in the longitudinal direction. In the side wall portion 34, the elastic member 32 is flat at a position away from the outer edge 3433 (that is, the outer edge in the width direction) of the flat portion 343 between the first flat sheet portion 3431 and the second flat sheet portion 3432. It is disposed over the entire length of the portion 343. As shown in FIG. 1, the planar portion 343 and the standing portion 342 are continuous from the two fixing portions 341 between the two fixing portions 341.

各サイドシート３では、２つの固定部３４１の間に弾性部材３２が伸張状態にて配置されており、弾性部材３２は、長手方向の両側の端部３２４にて２つの固定部３４１に接合される。また、弾性部材３２の両端部３２４の間の中間部３２５（すなわち、平面部３４３の第１平面シート部３４３１および第２平面シート部３４３２の間の部位）は、平面部３４３の長手方向の全長に亘って平面部３４３と非接合とされる。弾性部材３２の中間部３２５の長さは、側壁部３４を長手方向に伸張した状態において、好ましくは弾性部材３２の全長の６５％以上９０％以下とされる。吸収性物品１では、各サイドシート３の弾性部材３２が収縮することにより平面部３４３が収縮してギャザーが形成される。   In each side seat 3, the elastic member 32 is disposed in an extended state between the two fixing portions 341, and the elastic member 32 is joined to the two fixing portions 341 at both end portions 324 in the longitudinal direction. The Further, the intermediate portion 325 between both end portions 324 of the elastic member 32 (that is, the portion between the first flat sheet portion 3431 and the second flat sheet portion 3432 of the flat portion 343) is the total length in the longitudinal direction of the flat portion 343. The flat portion 343 is not joined over the entire area. The length of the intermediate portion 325 of the elastic member 32 is preferably 65% or more and 90% or less of the entire length of the elastic member 32 in a state where the side wall portion 34 is extended in the longitudinal direction. In the absorbent article 1, when the elastic member 32 of each side sheet 3 contracts, the flat portion 343 contracts to form a gather.

吸収性物品１が着用者に装着される際には、各サイドシート３に設けられた弾性部材３２が収縮することにより、本体部２の側方において側壁部３４の起立部３４２が着用者側に向かって起立するとともに平面部３４３が収縮してギャザーが形成される。すなわち、側壁部３４の固定部３４１の間の部位が立ち上がって立体ギャザーとなり、平面部３４３の着用者側の面である第１平面シート部３４３１（図２参照）が、着用者の足の付け根近傍の肌に対向する。そして、平面部３４３が足の付け根近傍の部位の形状に沿って変形しつつ第１平面シート部３４３１が足の付け根近傍の肌に密着する。   When the absorbent article 1 is attached to the wearer, the elastic member 32 provided on each side sheet 3 contracts, so that the upright part 342 of the side wall part 34 on the side of the main body 2 is on the wearer side. The flat portion 343 contracts and the gathers are formed. That is, the part between the fixing parts 341 of the side wall part 34 rises to form a three-dimensional gather, and the first flat sheet part 3431 (see FIG. 2), which is the wearer side face of the flat part 343, is the root of the wearer's foot. Opposes nearby skin. And the 1st plane sheet | seat part 3431 closely_contact | adheres to the skin of the base of a foot | base, deform | transforming along the shape of the site | part of the base of a foot | base.

このように、一対のサイドシート３の各側壁部３４が、幅が大きい平面部３４３にて着用者の肌に密着することにより、尿等の***物が平面部３４３よりも外側に移動して吸収性物品１から漏出することが防止される。吸収性物品１では、各サイドシート３において、平面部３４３を収縮させる弾性部材として帯状の弾性部材３２が第１平面シート部３４３１と第２平面シート部３４３２との間に設けられることにより、第１平面シート部３４３１と第２平面シート部３４３２との間に糸状の弾性部材のみが設けられる場合に比べて平面部３４３の形状安定性が向上される。これにより、平面部３４３の縒れ等が防止され、着用者に対する平面部３４３の密着性を向上することができる。その結果、サイドシート３の側壁部３４からの***物の漏出（いわゆる、横漏れ）がより確実に防止される。   In this way, the side walls 34 of the pair of side sheets 3 are brought into close contact with the wearer's skin by the flat portion 343 having a large width, so that excrement such as urine moves outside the flat portion 343. Leakage from the absorbent article 1 is prevented. In the absorbent article 1, in each side sheet 3, a belt-like elastic member 32 is provided between the first flat sheet portion 3431 and the second flat sheet portion 3432 as an elastic member that contracts the flat portion 343. The shape stability of the flat surface portion 343 is improved as compared with the case where only a thread-like elastic member is provided between the first flat sheet portion 3431 and the second flat sheet portion 3432. Thereby, the rolling etc. of the plane part 343 are prevented, and the adhesiveness of the plane part 343 with respect to a wearer can be improved. As a result, leakage of excrement from the side wall portion 34 of the side seat 3 (so-called side leakage) is more reliably prevented.

吸収性物品１では、各側壁部３４において、弾性部材３２の中間部３２５が平面部３４３と非接合とされることにより、平面部３４３の柔軟性（いわゆる、クッション性）が高められる。その結果、吸収性物品１の着用感が向上される。また、弾性部材３２が、側壁部３４の固定部３４１のみに接合され、平面部３４３の長手方向の全長に亘って平面部３４３と非接合とされることにより、平面部３４３の柔軟性がより高められ、吸収性物品１の着用感がさらに向上される。   In the absorbent article 1, the flexibility (so-called cushioning property) of the flat surface portion 343 is enhanced by making the intermediate portion 325 of the elastic member 32 non-joined with the flat surface portion 343 in each side wall portion 34. As a result, the wearing feeling of the absorbent article 1 is improved. Further, the elastic member 32 is joined only to the fixing part 341 of the side wall part 34 and is not joined to the flat part 343 over the entire length in the longitudinal direction of the flat part 343, whereby the flexibility of the flat part 343 is further increased. The wear feeling of the absorbent article 1 is further improved.

側壁部３４では、弾性部材３２が平面部３４３の外エッジ３４３３から幅方向の内側に離れた位置に配置されることにより、平面部３４３において着用者に比較的強く接触する外エッジ３４３３近傍の部位の柔軟性が高められる。これにより、吸収性物品１の着用感がより向上される。また、上述のように、弾性部材３２の平面部３４３と非接合とされる中間部３２５の長さが、弾性部材３２の全長の６５％以上とされることにより、柔軟な平面部３４３の長さが十分に確保されて吸収性物品１の着用感が向上され、さらに、中間部３２５の長さが弾性部材３２の全長の９０％以下とされることにより、弾性部材３２の両端部３２４（すなわち、弾性部材３２の中間部３２５の両側の部位）の長さが十分に確保されて弾性部材３２の固定部３４１に対する接合がより確実なものとされる。   In the side wall portion 34, the elastic member 32 is disposed at a position away from the outer edge 3433 of the flat surface portion 343 in the width direction, so that a portion of the flat surface portion 343 in the vicinity of the outer edge 3433 that contacts the wearer relatively strongly. Flexibility is increased. Thereby, the wearing feeling of the absorbent article 1 is further improved. Further, as described above, the length of the flexible flat portion 343 is set such that the length of the intermediate portion 325 that is not joined to the flat portion 343 of the elastic member 32 is 65% or more of the entire length of the elastic member 32. Is sufficiently secured and the wearing feeling of the absorbent article 1 is improved, and further, the length of the intermediate portion 325 is 90% or less of the entire length of the elastic member 32, whereby both end portions 324 ( In other words, the length of the portions on both sides of the intermediate portion 325 of the elastic member 32 is sufficiently secured, and the elastic member 32 is more reliably joined to the fixing portion 341.

サイドシート３では、側壁部３４の平面部３４３が、起立部３４２の上端から幅方向における外方へと広がることにより、平面部３４３が着用者の足の付け根近傍に沿いやすい形状となる。その結果、着用者に対する平面部３４３の密着性をより向上することができる。   In the side seat 3, the flat portion 343 of the side wall portion 34 spreads outward in the width direction from the upper end of the upright portion 342, so that the flat portion 343 has a shape that is easy to follow along the vicinity of the base of the wearer's foot. As a result, the adhesion of the flat surface portion 343 to the wearer can be further improved.

吸収性物品１では、弾性部材３２として、帯状のポリウレタンフィルムや帯状の天然ゴム等が用いられてもよいが、上述のように、弾性部材３２が、重ねられた２枚の帯状部材３２１，３２２の間に複数の弾性部材３２が接合された構造とされることにより、帯状のポリウレタンフィルム等が利用される場合に比べて弾性部材３２の強度が高くされる。これにより、平面部３４３の形状安定性がより向上され、平面部３４３の着用者に対する密着性をさらに向上することができる。また、弾性部材３２の製造コストを低減することもできる。   In the absorbent article 1, a belt-like polyurethane film, a belt-like natural rubber, or the like may be used as the elastic member 32, but as described above, the two belt-like members 321 and 322 in which the elastic member 32 is overlaid. By having a structure in which a plurality of elastic members 32 are joined between the two, the strength of the elastic members 32 is increased as compared with the case where a strip-like polyurethane film or the like is used. Thereby, the shape stability of the plane part 343 is further improved, and the adhesion of the plane part 343 to the wearer can be further improved. Moreover, the manufacturing cost of the elastic member 32 can also be reduced.

以上、本発明の実施の形態について説明してきたが、本発明は上記実施の形態に限定されるものではなく、様々な変更が可能である。   As mentioned above, although embodiment of this invention has been described, this invention is not limited to the said embodiment, A various change is possible.

例えば、弾性部材３２の両端部３２４は、側壁部３４の固定部３４１と平面部３４３との境界を跨いで固定部３４１および平面部３４３の双方に接合されてもよい。また、弾性部材３２は、必ずしも平面部３４３の全長に亘って設けられる必要はなく、伸張状態において平面部３４３の長さよりも多少短い弾性部材３２が、固定部３４１と重なることなく平面部３４３の長手方向のほぼ全長に亘って設けられてもよい。この場合、弾性部材３２の両端部３２４は平面部３４３の固定部３４１近傍の部位に接合される。すなわち、各サイドシート３では、弾性部材３２の長手方向の両端部３２４は、２つの固定部３４１および平面部３４３の少なくとも一方に接合される。   For example, both end portions 324 of the elastic member 32 may be joined to both the fixed portion 341 and the flat portion 343 across the boundary between the fixed portion 341 and the flat portion 343 of the side wall portion 34. Further, the elastic member 32 is not necessarily provided over the entire length of the flat surface portion 343, and the elastic member 32 that is slightly shorter than the length of the flat surface portion 343 in the extended state does not overlap the fixing portion 341. It may be provided over substantially the entire length in the longitudinal direction. In this case, both end portions 324 of the elastic member 32 are joined to portions near the fixed portion 341 of the flat surface portion 343. That is, in each side sheet 3, both end portions 324 in the longitudinal direction of the elastic member 32 are joined to at least one of the two fixing portions 341 and the flat portion 343.
