Description

特許文献１の吸収性物品は、前身頃の脚回り弾性部材と後身頃の脚回り弾性部材とがずれている部分では、前身頃側の伸縮力と後身頃側の伸縮力が異なり、接合部が前身頃又は後身頃に寄せられることが考えられる。 The absorbent article of Patent Document 1, in the portion where the leg elastic members of the leg elastic members and the back body of the front body are shifted, different stretching force and the back body side of the stretching force of the front body side, the joint May be brought to the front or back.

しかし、前身頃の脚回り弾性部材と後身頃の脚回り弾性部材とがずれている部分において、サイド接合部の一部が前身頃側か後身頃側に寄せられた場合であっても、前後方向内側端部（股下側の端部）が前身頃又は後身頃に十分に寄せられず、接合部の前後方向内側端部が着用者の脚に当たるおそれがある。 However, before the leg elastic members and the leg elastic members and a portion is displaced in the rear body of the body, even if a part of the side joint is provided by, the rear body side or front body side, front and rear The inner end in the direction (the end on the crotch side) is not sufficiently brought close to the front body or the rear body , and the inner end in the front-rear direction of the joint may hit the wearer's leg.

本発明に係る吸収性物品は、身体前側と身体後側とに延びる前後方向と、前記前後方向に直交する幅方向と、前記着用者に向かう内方向及び前記内方向と反対側に向かう外方向を有する厚み方向とを有する吸収体を有する吸収性本体と、前記吸収性本体よりも前記外方向に配置される外装体と、を備え、着用者の腹側に配置される前胴回り域と、着用者の背側に配置される後胴回り域と、前記前胴回り域と前記後胴回り域との間に位置し、着用者の股下に配置される股下域とを有し、前記外装体の前記前胴回り域の前記幅方向外側端部と前記外装体の前記後胴回り域の前記幅方向外側端部とが接合された一対のサイド接合部が形成されることにより、前記着用者の脚が挿入される一対の脚回り開口部が設けられるパンツタイプの吸収性物品であって、前記外装体には、前記前胴回り域又は前記後胴回り域の一方の脚回り開口部に沿って配置された複数の第１弾性部材と、前記前胴回り域又は前記後胴回り域の他方の脚回り開口部に沿って配置された複数の第２弾性部材と、が設けられており、前記複数の第１弾性部材及び前記複数の第２弾性部材が伸長した伸長状態において、前記複数の第１弾性部材のうち最も前記脚回り開口部側に位置する端部第１弾性部材と前記幅方向に延びる仮想線とがなす角度は、前記複数の第２弾性部材のうち最も前記脚回り開口部側に位置する端部第２弾性部材と前記仮想線とがなす角度よりも大きく、前記端部第２弾性部材の前記幅方向の伸縮力は、前記端部第１弾性部材の前記幅方向の伸縮力よりも高いことを要旨とする。 Absorbent article according to the present invention, a longitudinal direction extending in the body front and the body rear side, a width direction perpendicular to the longitudinal direction, an outer direction toward the side opposite to the direction and the plane direction within toward the wearer A front waistline region disposed on the abdomen side of the wearer, comprising an absorbent body having an absorbent body having a thickness direction and an exterior body disposed more outward than the absorbent body; A rear waistline region disposed on the back side of the wearer, and a crotch region located between the front waistline region and the back waistline region and disposed on the wearer's inseam, The wearer's leg is inserted by forming a pair of side joints in which the widthwise outer end of the front waistline and the widthwise outer end of the rear waistline of the exterior body are joined. A pants-type absorbent article provided with a pair of leg openings. The outer body includes a plurality of first elastic members disposed along one leg opening of the front waistline or the rear waistline, and the other of the front waistline or the rear waistline. A plurality of second elastic members disposed along the leg opening of the plurality of legs, and in the extended state where the plurality of first elastic members and the plurality of second elastic members are extended, The angle formed by the end first elastic member located closest to the leg opening portion of the first elastic member and the imaginary line extending in the width direction is the most around the leg opening of the plurality of second elastic members. The expansion / contraction force in the width direction of the end second elastic member is larger than the angle formed by the end second elastic member located on the portion side and the imaginary line, and the width direction of the end first elastic member is The gist is that it is higher than the elastic force of

後弾性部材５５は、脚回り開口部に沿って配置された３本の後脚回り弾性部材５７と、後脚回り弾性部材５７よりも前後方向外側に位置する後胴回り弾性部材５６と、を有する。後胴回り弾性部材５６は、幅方向に沿って配置されている。後胴回り弾性部材５６は、７８０ｄｔｅｘの太さ、２．１倍の伸長率で、１０本伸長固定される。 The rear elastic member 55 includes three rear leg elastic members 57 arranged along the leg opening, and a rear waist elastic member 56 positioned on the outer side in the front-rear direction than the rear leg elastic member 57. . The rear waistline elastic member 56 is disposed along the width direction. Ten rear waistline elastic members 56 are stretched and fixed at a thickness of 780 dtex and an elongation ratio of 2.1 times.
