本発明において、上述の吸収体を構成する第1吸収層及び第2吸収層として用い得る吸収性部材は、尿などの排泄液を吸収して保持することができるものであれば特に制限されず、当分野において公知の任意の吸収性部材を用いることができる。 In the present invention, the first absorbent layer and an absorbent member which can be used as the second absorbent layer forming the absorbent body described above is not particularly limited as long as it can be absorbing and retaining bodily fluid such as urine it can be used any known absorbent member in the art. そのような吸収性部材としては、例えば、任意の吸収性材料によって構成される吸収コアを、親水性を有するティッシュ等のコアラップシートで覆ったものなどを用いることができる。 Such absorbent members, for example, an absorbent core composed of any absorbent material can be used such as those covered by the core wrap sheets of tissue or the like having a hydrophilic. さらに、上述の吸収コアを構成する吸収性材料としては、例えば、親水性繊維や高吸収性ポリマーなどを用いることができ、更に具体的には、粉砕パルプ、コットン、レーヨン、アセテート等のセルロース系繊維;アクリル酸ナトリウムコポリマー等の高吸収性ポリマーからなる粒状物などを用いることができる。 Furthermore, as the absorbent material constituting the absorbent core described above, for example, it can be used as the hydrophilic fibers and superabsorbent polymer, and more specifically, ground pulp, cotton, rayon, cellulose such as acetate fibers; and particulates comprising a superabsorbent polymer such as sodium acrylate copolymer can be used. これらの吸収性材料は、1種類の吸収性材料を単独で用いても、2種類以上の吸収性材料を併用してもよい。 These absorbent materials can be used one type of absorbent material alone or in combination of two or more absorbent materials. なお、第1吸収層と第2吸収層は、同じ構成の吸収性部材を用いても、異なる構成の吸収性部材を用いてもよい。 The first absorbent layer and a second absorbent layer, even with an absorbent member having the same construction may be used an absorbent member of a different configuration.

また、上述の実施形態において、第1吸収層21Aは、図1及び図6に示すように、平面視にて、少なくとも股間部領域A の幅方向Wの中央部(すなわち、長手方向Lに延びる幅方向中央軸線C と重複する部分)に、当該第1吸収層21Aを厚さ方向Tに貫通する貫通孔21A を備えており、さらに、第2吸収層21Bも、図1に示すように、股間部領域A の幅方向Wの中央部であって第1吸収層21Aの貫通孔21A と厚さ方向Tに重複する位置に、平面視にて貫通孔21A よりも小さい寸法形状を有し且つ第2吸収層21Bを厚さ方向Tに貫通する貫通孔21B を備えている。 In the above embodiment, the first absorbent layer 21A, as shown in FIGS. 1 and 6, in plan view, the central portion in the width direction W of at least the crotch region A C (i.e., in the longitudinal direction L the widthwise central axis C L and overlapping portions) extending includes a through hole 21A S penetrating the first absorbent layer 21A in the thickness direction T, furthermore, also the second absorbent layer 21B, shown in FIG. 1 as described above, in a position overlapping a central portion in the width direction W of the crotch region a C into the through hole 21A S and the thickness direction T of the first absorbent layer 21A, it is smaller than the through-hole 21A S in a plan view and a through hole 21B S penetrating the and second absorbing layer 21B has a size and shape in the thickness direction T. これらの貫通孔21A 及び貫通孔21B は、厚さ方向Tにおいて連通しており、全体として吸収体21を厚さ方向Tに貫通し且つ当該厚さ方向Tにおいて開孔面積が段階的に異なる貫通孔を形成している。 These through holes 21A S and the through hole 21B S is communicated in the thickness direction T, the absorber 21 through the thickness direction T and the gradual are opening area in the thickness direction T as a whole forming a different through-holes.
吸収体が、このような貫通孔を備えていると、排泄液の厚さ方向Tへの吸収を促すことができるため、より優れた吸収性能(特に、吸収速度)を発揮することができる。 Absorber, when provided with such a through-hole, it is possible to promote absorption of the thickness direction T of the liquid waste, better absorbing performance (in particular, absorption rate) can exhibit.

なお、本発明の吸収性物品においては、吸収体は、上述の実施形態のような2層の吸収層によって構成されている必要はなく、吸収体は、単層構造を有する吸収性部材によって構成されていても、3層以上の複層構造を有する吸収性部材によって構成されていてもよい。 In the absorbent article of the present invention, the absorbent body need not be constituted by the absorbing layer of the two-layer such as the embodiment described above, the absorber, composed of absorbent member having a single-layer structure it is, may be constituted by absorbent member having three or more layers of a multilayer structure.
吸収体を構成する吸収層として用い得る吸収性部材の坪量や厚み等は、当該吸収性部材が吸収性物品の吸収体として機能し得る諸特性(例えば、吸収性、柔軟性等)を有するものであれば特に制限されず、任意の坪量及び厚み等を採用することができる。 The basis weight and thickness, and the like of the absorbent member which can be used as an absorbent layer which constitutes the absorbent body has the characteristics which the absorbent member can function as an absorber of an absorbent article (e.g., absorption, flexibility, etc.) It not particularly limited as long as it is possible to adopt such an arbitrary basis weight and thickness.

また、上述の実施形態では、吸収体21は、股間部領域A において、幅方向Wの両端縁(すなわち、幅方向Wの一方側端縁21E 及び他方側端縁21E )が一対の防漏壁部の各々の基部41の幅方向Wにおける内方側端縁よりも幅方向Wの内方側に位置する部分を有するように、幅方向Wの内方側に向かって括れた外形形状を有している。 In the embodiment described above, the absorber 21, in the crotch region A C, both edges in the width direction W (i.e., one side edge 21E 3 and the other side edge 21E 4 in the width direction W) of the pair so as to have a portion located inward in the width direction W than the inner side edge in the width direction W of each of the base portion 41 of the leakage preventing wall portion, the outer shape having a constricted toward the inner side in the width direction W It has a shape. 吸収体21がこのような外形形状を有していると、股間部領域A において、吸収体21による剛性への影響が小さく、上述の一対の防漏壁部の変形及び移動の自由度が高くなるため、着用者が尿取りパッド1を着用した際に、上述の一対の防漏壁部を着用者の身体形状(股間部の形状)に追従させながら密着させることができる。 When the absorbent body 21 has such a contour, the crotch region A C, a small influence on the rigidity by the absorber 21, that variations and freedom of movement of the pair of leak-barrier walls of the above because higher, can wearer when wearing the urine absorbing pad 1, it is brought into close contact while tracking a pair of leak-barrier walls of the above the wearer's body shape (the shape of the crotch portion). したがって、このような外形形状を有する吸収体21を備えた尿取りパッド1は、着用者の身体(股間部)と一対の防漏壁部との間に隙間が形成され難いため、排泄液の横漏れをより確実に防ぐことができる。 Thus, the urine absorbing pad 1 having an absorber 21 having such a contour shape of the wearer's body since it is difficult gap is formed between the (crotch portion) and a pair of leak-barrier walls portions, the liquid waste it is possible to prevent side leakage more reliably.

さらに、上述の実施形態では、吸収体21は、腹部領域A 及び背部領域A において、吸収体21の幅方向Wにおける両端縁(すなわち、幅方向Wの一方側端縁21E 及び他方側端縁21E )が一対の防漏壁部の各々の第2接合部45の幅方向Wにおける外方側端縁よりも幅方向Wの外方側に位置する部分を有するように配置されている。 Furthermore, in the embodiment described above, the absorber 21 is in the abdominal region A F and back region A B, both edges in the width direction W of the absorber 21 (i.e., one side edge 21E 3 and the other side in the width direction W and edge 21E 4) are arranged to have a portion located outer side in the width direction W than the outer side edge in the width direction W of the second joint 45 of each of the pair of leakage preventing walls portions there. 吸収体21がこのように配置されていると、着用者が横向きに寝ているような場合(すなわち、着用者から排出される排泄液が重力方向(より具体的には、吸収本体部2の幅方向Wの外方側へ向かう方向)に流れ易いような場合)でも、幅方向Wの外方側に向かって流れる排泄液を吸収体21によって着実に吸収することができ、排泄液の横漏れを更に確実に防ぐことができる。 When absorber 21 is arranged in this manner, the wearer may as sleeping sideways (i.e., the liquid waste is gravity direction (more specifically discharged from the wearer, the absorbent main body 2 If the direction) toward the outer side in the width direction W flows easily like) but can be steadily absorbed by the absorber 21 the liquid waste flowing toward the outer side in the width direction W, next to the liquid waste it is possible to prevent leakage more reliably.

なお、本発明の吸収性物品においては、一対の防漏壁部の各々における液流動制御部は、少なくとも背部領域に配置されていればよいが、上述の実施形態に係る尿取りパッド1では、液流動制御部F は、腹部領域A 及び背部領域A の各々に配置されており、さらに、吸収体21は、図1に示すように、平面視にて、当該吸収体21の長手方向Lにおける腹部領域側端縁21E が腹部領域A に配置された液流動制御部F の第2接合部45の幅方向Wにおける内方側端縁のうち長手方向Lの最も内方側に位置する内方側端部45E よりも長手方向Lの外方側に位置し、且つ、吸収体21の幅方向Wにおける両端縁(すなわち、幅方向Wの一方側端縁21E 及び他方側端縁21E )が腹部領域A において基部41の幅 In the absorbent article of the present invention, the liquid flow control unit in each of the pair of leak-barrier walls unit may be disposed in at least the back region, but in the urine absorbing pad 1 according to the embodiment described above, liquid flow control unit F C is arranged in each of the abdominal area a F and back region a B, furthermore, the absorbent body 21, as shown in FIG. 1, in plan view, longitudinal of the absorbent body 21 innermost longitudinal direction L of the inner side edge abdominal area side edge 21E 2 in the direction L is in the width direction W of the second joint portion 45 of the disposed liquid flow control unit F C to the abdominal area a F than the inner-side end portion 45E i located on the side located on the outer side of the longitudinal direction L, and, both edges in the width direction W of the absorber 21 (i.e., one side edge 21E 3 and the width direction W the other side edge 21E 4) width of the base portion 41 in the abdominal region a F 向Wにおける内方側端縁よりも幅方向Wの外方側に位置するように、吸収本体部2内に配置されている。 So as to be positioned on the outer side in the width direction W than the inner side edge in the direction W, and is located in the absorbent body unit 2.
吸収体21がこのように配置されていると、着用者がうつ伏せ状態で寝ているような場合(すなわち、着用者から排出される排泄液が重力方向(より具体的には、吸収本体部2の幅方向Wの外方側へ向かう方向)に流れ易いような場合)でも、上述の腹部領域A に配置された液流動制御部F によって、当該腹部領域A における排泄液の横漏れを着実に防ぎつつ、長手方向Lにおける腹部側からの漏れをも生じ難くすることができる。 When absorber 21 is arranged in this way, if as sleeping state wearer prone (i.e., the liquid waste is gravity direction (more specifically discharged from the wearer, the absorbent main body 2 But if the direction) toward the outer side of the width direction W, such as to facilitate the flow), the arranged liquid flow control unit F C to the abdominal area a F of the above, the lateral leakage of liquid waste in the abdominal area a F steadily while preventing, it can be difficult to occur also leak from the abdomen side in the longitudinal direction L.

[エンボス部] [Embossed portion]
上述の実施形態において、吸収本体部2は、長手方向Lに延びる幅方向中央軸線C によって区画される幅方向第1領域A W1及び幅方向第2領域A W2の各々に配置され且つ肌対向面から厚さ方向Tに窪む一対のエンボス部3、3を有している。 In the above embodiment, the absorbent body 2, and the skin-facing arranged on each of the longitudinal width direction center axis extending in the L C L widthwise first region partitioned by A W1 and the width direction second region A W2 and a pair of embossed portions 3 recessed in the thickness direction T from the surface. かかる一対のエンボス部3、3の各々は、図1に示すように、股間部領域A において、長手方向Lに延びる直線状の平面視形状を有しており、さらに、吸収本体部2の厚さ方向Tにおいて、肌対向面側から窪みつつ、表面シート22と吸収体21が圧搾により一体化されている。 Each such pair of embossed portions 3, 3, as shown in FIG. 1, in the crotch region A C, has a linear shape in plan view extending in the longitudinal direction L, more, of the absorbent main body 2 in the thickness direction T, while the depression from the skin facing side, the absorbent body 21 are integrated by pressing the topsheet 22. なお、このようなエンボス部は、加熱又は非加熱の任意のエンボス加工手段を用いて、吸収本体部を肌対向面から厚さ方向Tに圧搾することにより形成することができる。 Note that such embossed portions, using any embossing means or without heating, it can be formed by compressing in the thickness direction T of the absorbent main body from the skin-facing surface.

そして、本実施形態においては、一対のエンボス部3、3は、当該エンボス部3から基部41の幅方向Wにおける内方側端縁までの幅方向長さ、第1壁部42の幅方向長さ及び第2壁部43の幅方向長さの合計長さが、上述の幅方向中央軸線C からエンボス部3まで(具体的には、エンボス部3の幅方向の中心線まで)の幅方向長さよりも長くなるように配置されている。 Then, in the present embodiment, a pair of embossed portions 3, 3, the length in the width direction from the embossed portion 3 to the inner side edge in the width direction W of the base portion 41, the width direction length of the first wall portion 42 and the width direction length total length of the second wall portion 43, the width from the widthwise center axis C L described above to embossed portions 3 (specifically, to the center line in the width direction of the embossed portion 3) It is arranged so as to be longer than the length in the direction. 一対のエンボス部3、3がこのように配置されていると、当該一対のエンボス部3、3が折れ曲がり起点となって、吸収本体部2の幅方向中央軸線C に沿って延びる幅方向中央部が肌対向面側に向かって突出するように(すなわち、長手方向中央軸線C に沿った断面形状が略W字形となるように)吸収本体部2が変形し易くなる上、上述の一対の防漏壁部の起立高さが、肌対向面側に向かって突出する幅方向中央部の突出高さよりも高くなり易くなるため、吸収本体部2の幅方向中央部における肌対向面を着用者の股間部に密着又は近接させて、着用者から排出される排泄液を吸収体21に吸収させ易くすることができるとともに、排泄液の横漏れをより確実に防ぐことができる。 When a pair of embossed portions 3, 3 are arranged in this manner, become a starting point the pair of embossed portions 3, 3 bent, widthwise center extending along the widthwise center axis C L of the absorbent main body 2 part is to project toward the skin-facing side (i.e., as the cross-sectional shape along a longitudinal central axis C W become substantially W-shape) on the absorption body portion 2 is easily deformed, a pair of above wear standing height of the leakage preventing walls portions, since likely be higher than the protruding height of the widthwise central portion projecting toward the skin-facing side, a skin-facing surface in the widthwise central portion of the absorbent main body portion 2 of who in close contact with or close to the crotch portion, it is possible to easily absorbed into the absorbent body 21 the liquid waste discharged from the wearer, it is possible to prevent side leakage of bodily fluid more reliably.

なお、このような作用効果は、一対のエンボス部が吸収本体部の折れ曲がり起点となり得るものであれば、上述の実施形態以外の態様でも同様に奏されるため、本発明において、一対のエンボス部は、上述の実施形態のように、必ずしも表面シートと吸収体が一体化されるように形成されている必要はなく、例えば、吸収体のみに形成されていてもよい。 It should be noted that such advantages are, as long as a pair of embossed portions can become a bending starting point of the absorbent main body, because they are achieved as well in a manner other than the above-described embodiments, the present invention, a pair of embossed portions , as in the embodiment described above, not necessarily the topsheet and the absorbent body is formed so as to be integrated, for example, it may be formed only on the absorber.

本発明において、一対のサイドシートに配置される複数本の弾性部材は、展開した状態の吸収本体部(具体的には、一対のサイドシートを介して吸収本体部)に長手方向の収縮力を付与し得る材料であれば特に制限されず、例えば、天然ゴムからなる糸ゴムや平ゴム;ウレタン、エチレン−酢酸ビニル共重合体(EVA)等の熱可塑性エラストマーを糸状又は帯状に成形したものなどの任意の弾性部材を用いることができる。 In the present invention, a plurality of elastic members disposed on the pair of side sheets (specifically, the absorbent main body via a pair of side sheets) absorbing body of the developed state of a longitudinal contractive force in any material capable of imparting not particularly limited, for example, rubber thread and flat rubber consisting of natural rubber; urethane, ethylene - thermoplastic elastomers such as vinyl acetate copolymer (EVA) such as those molded to the string or strip it is possible to use any elastic member.

本発明の吸収性物品に用い得る弾性部材の寸法形状は、サイドシートを介して展開した状態の吸収本体部を長手方向に収縮し得るものであれば特に制限されず、吸収性物品の用途やサイズなどに応じた任意の寸法形状を採用することができる。 Geometry of the elastic member can be used in the absorbent article of the present invention, if the absorption body of the developed state through the side sheet as it is capable of shrinking in the longitudinal direction is not particularly limited, Ya application of the absorbent article it is possible to employ any size and shape corresponding to the size, etc.. そのような寸法形状としては、例えば、弾性部材の長手方向長さが、吸収性物品の全長の1/4以上、好ましくは1/3以上であり、繊度が200dtex〜800dtexの範囲内、好ましくは300dtex〜700dtexの範囲内である。 Such dimensions, for example, the longitudinal length of the elastic member, the absorbent of the total length of the article 1/4 or more, preferably 1/3 or more, the range fineness of 200Dtex~800dtex, preferably it is within the range of 300dtex~700dtex. なお、弾性部材の本数も、サイドシートを介して展開した状態の吸収本体部を長手方向に収縮し得るものであれば特に制限されず、弾性部材は、一対の防漏壁部の各々に、1本や2本、3本以上等の任意の本数ずつ配置することができる。 Also the number of the elastic members, when the absorption body of the developed state through the side sheet as it is capable of shrinking in the longitudinal direction is not particularly limited, the elastic member, each of the pair of leakage preventing walls portions, one or two, it may be arranged one by any number of three or more like.

また、上述の実施形態に係る尿取りパッド1においては、一対の防漏壁部(サイドシート)の各々に配置された5本(複数本)の弾性部材ELは、図1に示すように、幅方向Wの外方側に位置する弾性部材ELの長手方向長さが、幅方向Wの内方側に位置する弾性部材ELの長手方向長さよりも長く形成されている。 The elastic members EL in the urine absorbing pad 1 according to the embodiment described above, a pair of leak-barrier walls 5 present, which is arranged in each of the (side sheets) (plural), as shown in FIG. 1, longitudinal length of the elastic members EL positioned on the outer side in the width direction W is formed longer than the longitudinal length of the elastic members EL positioned inward in the width direction W. このように、幅方向Wの外方側に位置する弾性部材ELの長手方向長さが幅方向Wの内方側に位置する弾性部材ELの長手方向長さよりも長く形成されていると、一対の防漏壁部の幅方向Wにおける外方側部分においては、第1壁部42及び第2壁部43による起立構造を維持し易くなり、幅方向Wの外方側へ向かう排泄液に対する耐久性を更に確保することができる一方、一対の防漏壁部の幅方向Wにおける内方側部分(すなわち、一対の防漏壁部の起立起点となる部分及び頂部となる部分)においては、変形や移動の自由度が高くなり、一対の防漏壁部を着用者の身体形状(股間部の形状)に追従させながら密着させ易くすることができる。 Thus, when the is formed longer than the longitudinal length of the elastic members EL located inward of the longitudinal length in the width direction W of the elastic member EL positioned on the outer side in the width direction W, the pair in the outer side portion in the width direction W of the leakage preventing walls unit, apt to maintain the standing structure by the first wall portion 42 and the second wall portion 43, the durability against liquid waste toward the outer side in the width direction W while it is possible to further ensure the gender, in inner side portion of the width direction W of the pair of leak-barrier walls portions (i.e., the portion to be the portion and top portion a standing start point of the pair of leakage preventing walls unit), modified and freedom of movement is increased, it is possible to easily brought into close contact while tracking a pair of leakage preventing walls portions to the wearer's body shape (the shape of the crotch portion). これにより、このような複数本の弾性部材が配置された尿取りパッド1は、一対の防漏壁部の防漏機能をより良好に発揮させることができる。 Thus, the urine absorbing pad 1 having elastic members arranged in such a plurality may be exhibited better the leakage prevention function of the pair of leakage preventing walls portion.

また、上述の実施形態に係る尿取りパッド1においては、一対の防漏壁部の各々は、平面視にて、複数本の弾性部材ELによって長手方向Lに収縮可能に形成された、長手方向Lに延在する収縮領域を有していて、当該収縮領域は、幅方向Wの内方側に位置する部分の長手方向長さが、幅方向Wの外方側に位置する部分の長手方向長さよりも長く形成されている。 In the urine absorbing pad 1 according to the embodiment described above, each of the pair of leak-barrier walls section, in plan view, which is contractible formed in the longitudinal direction L by an elastic member EL a plurality of longitudinal have extended contracts region L, and the contraction region, the longitudinal length of the portion located inward in the width direction W is the longitudinal direction of the portion located on the outer side in the width direction W It is formed longer than the length. このように、一対の防漏壁部の各々の収縮領域において、幅方向Wの内方側に位置する部分の長手方向長さが幅方向Wの外方側に位置する部分の長手方向長さよりも長く形成されていると、一対の防漏壁部の各々において、頂部となる部分が捲れ上がり難くなり、当該一対の防漏壁部の防漏機能をより確実に発揮させることができる。 Thus, in each of the contraction region of the pair of leakage preventing walls section, than the longitudinal length of the portion longitudinal length of the portion located inward in the width direction W is positioned on the outer side in the width direction W If is also formed longer, in each of the pair of leakage preventing walls portions, portions to be the top portion is difficult to increase turning up, it is possible to more reliably exhibit the leakage prevention function of the pair of leakage preventing walls portion.

さらに、上述の実施形態では、吸収体21は、図1に示すように、腹部領域A において吸収体21の幅方向Wの長さが最も長い部分である幅広部21Mと、腹部領域A 及び股間部領域A の境界部分において吸収体21の幅方向Wの長さが幅広部21Mの幅方向Wの長さ(すなわち、腹部領域A における吸収体21の幅方向Wの最大長さ)よりも小さい幅狭部21Nと、を有していて、当該幅狭部21Nは、平面視にて上述の収縮領域と重複している。 Furthermore, in the embodiment described above, the absorber 21, as shown in FIG. 1, and the wide portion 21M length in the width direction W of the absorber 21 is the longest part in the abdominal area A F, abdominal area A F and crotch area a C of the length in the width direction W length of the wide portion 21M in the width direction W of the absorber 21 at the boundary (i.e., the maximum length in the width direction W of the absorber 21 in the abdominal area a F ) have a small narrow portion 21N than the narrow portion 21N is overlapped with the above contraction region in plan view. このように、腹部領域A 及び股間部領域A の境界部分において、吸収体21の幅方向Wの長さが腹部領域A における吸収体21の幅方向Wの最大長さよりも小さい幅狭部21Nを有していると、当該幅狭部21Nを有する部分の尿取りパッド1の剛性が相対的に低くなるため、尿取りパッド1を着用する際に、当該尿取りパッド1が、上述の幅狭部21Nを有する部分を起点として肌対向面側の表面が凹むように曲がり易くなる。 Thus, at the boundary of the abdominal area A F and crotch area A C, less narrower than the maximum length in the width direction W of the absorber 21 the length in the width direction W of the absorber 21 in the abdominal area A F as having a section 21N, the rigidity of the urine absorbing pad 1 of the portion having the narrow width portion 21N is relatively low, when wearing the urine absorbing pad 1, the incontinence pad 1, above easily bend a width portion having a narrow portion 21N of so that the surface of the skin-facing surface side recessed starting. その上、かかる尿取りパッド1は、平面視にて、幅狭部21Nが上述の収縮領域と重複しているため、当該尿取りパッド1を着用する際に、曲率の大きい腹部領域A と股間部領域A との境界部分(すなわち、幅狭部21Nと厚さ方向Tに重複する部分)において、防漏壁部の第2壁部43の肌対向面側の表面が、図7に示すように、吸収本体部2の肌対向面側の表面と略平行な面状の形態を維持したまま、上述の防漏壁部が肌対向面側に向かって起立し易くなる。 Moreover, according urine absorbing pad 1, in plan view, since the narrow portion 21N is duplicated with the above contraction region, when wearing the urine absorbing pad 1, a large abdominal area A F of curvature boundary between the crotch region a C (i.e., the portion that overlaps the narrow portion 21N and the thickness direction T) in the skin facing side of the surface of the second wall portion 43 of the leakage preventing wall is in Figure 7 as shown, while maintaining the surface substantially parallel to the planar form of the skin-facing side of the absorbent main body 2, the leakage preventing walls of the above is likely to stand up toward the skin-facing surface side. これにより、かかる尿取りパッド1は、着用する際に曲率が大きくなる部分(すなわち、腹部領域A と股間部領域A との境界部分)の防漏壁部と、着用者の肌面との接触面積をより大きく確保することができる(換言すれば、防漏壁部と着用者の肌面との間に、隙間を形成し難くすることができる)ため、排泄液の横漏れを更に確実に防ぐことができる。 Thus, according urine absorbing pad 1, a leakage preventing wall of the portion where the curvature is increased when worn (i.e., the abdominal area A F and the boundary portion between the crotch region A C), and the skin surface of the wearer greater can be secured area of ​​contact (in other words, between the wearer's skin surface and the leakage preventing wall can be difficult to form a gap) for further side leakage excretions it is possible to reliably prevent.
