Abstract:
(EN) Provided is a diaper equipped with an absorbent main body (11), an abdomen-side waist portion (2), and a back-side waist portion (3), wherein the absorbent main body (11) has a top sheet (51) in which a plurality of convex portions (511) formed along the longitudinal direction are provided at a predetermined pitch (W1) in the lateral direction, an abdomen-side elastic region (X2) stretching in the lateral direction is provided to the abdomen-side waist portion (2) so as to intersect the plurality of convex portions (511) on one end portion (11A) of the absorbent main body (11), a back-side elastic region (X3) stretching in the lateral direction is provided to the back-side waist portion (3) so as to intersect the plurality of convex portions (511) on the other end portion (11B) of the absorbent main body (11), and the maximum lateral-direction spacing (W3) of a plurality of wrinkles (110) of the abdomen-side distal end region (11Af) and/or the maximum lateral-direction spacing (W3) of a plurality of wrinkles (110) of the back-side distal end region (11Bb) is greater than the prescribed pitch (W1) of the convex portions (511) in a longitudinal-direction center portion in a state in which the abdomen-side elastic region (X2) and the back-side elastic region (X3) are contracted in the lateral direction.
(FR) L'invention concerne une couche équipée d'un corps principal absorbant (11), d'une partie de taille côté abdomen (2) et d'une partie de taille côté arrière (3), lequel corps principal absorbant (11) comprend une feuille supérieure (51) dans laquelle une pluralité de parties convexes (511) formées dans le sens longitudinal sont agencées avec un pas prédéterminé (W1) dans le sens latéral, une région élastique côté abdomen (X2) s'étirant dans le sens latéral est placée sur la partie de taille côté abdomen (2) de façon à croiser la pluralité de parties convexes (511) sur une partie d'extrémité (11A) du corps principal absorbant (11), une zone élastique côté arrière (X3) s'étirant dans le sens latéral est placée sur la partie de taille côté arrière (3) de manière à croiser la pluralité de parties convexes (511) sur l'autre partie d'extrémité (11B) du corps principal absorbant (11) et l'espacement maximal dans le sens latéral (W3) d'une pluralité de plis (110) de la région d'extrémité distale côté abdomen (11Af) et/ou l'espacement maximal dans le sens latéral (W3) d'une pluralité de plis (110) de la région d'extrémité distale côté arrière (11Bb) est supérieur au pas prescrit (W1) des parties convexes (511) dans une partie centrale dans le sens longitudinal dans un état dans lequel la région élastique côté abdomen (X2) et la région élastique côté arrière (X3) sont comprimés dans le sens latéral.
(JA) 吸収性本体(11)と、腹側胴回り部(2)と、背側胴回り部(3)と、を備えたおむつ1であって、吸収性本体(11)は、長手方向に沿って形成された凸部(511)が横方向に所定のピッチ(W1)で複数設けられたトップシート(51)を有し、腹側胴回り部(2)には、横方向に伸縮する腹側弾性領域(X2)が吸収性本体(11)の一端部(11A)における複数の凸部(511)と交差するように設けられ、背側胴回り部(3)には、横方向に伸縮する背側弾性領域(X3)が吸収性本体(11)の他端部(11B)における複数の凸部(511)と交差するように設けられ、腹側弾性領域(X2)及び背側弾性領域(X3)が横方向に収縮した状態において、腹側先端領域(11Af)の複数の皺(110)の横方向の最大間隔(W3)、及び背側先端領域(11Bb)の複数の皺(110)の横方向の最大間隔(W3)のうちの少なくとも一方が、長手方向の中央部における凸部(511)の所定のピッチ(W1)よりも大きい。
