Abstract
(EN)
A disposable diaper (1) includes an absorbent member (4) containing an oblong absorbent core (40) and has a front portion (A), a crotch portion (C), and a rear portion (B). The absorbent core (4) has a high basis weight region (41) in a laterally middle part of the crotch portion (C) and a low basis weight region (42) having a lower basis weight than the high basis weight region (41) on both sides of the high basis weight region (41). The absorbent core (40) has a central bending-inducing region (43) extending in its longitudinal direction in the form of a slit, a groove, or a fiber-tree region in the high basis weight region (41) and a side bending-inducing region (44) in the form of a fiber-free region in each low basis weight region (42). The central bending-inducing region (43) extends toward the front end of the absorbent core (40) beyond the front end of each side bending-inducing region (44), and the side bending-inducing regions (44) extend toward the rear end of the absorbent core (40) beyond the rear end of the central bending-inducing region (43).

(FR)
La présente invention concerne une couche jetable (1) qui est dotée d'un corps absorbant (4) contenant un corps absorbant oblong (40) et comprenant une partie abdominale (A), une partie d'entre-jambe (C) et une partie arrière (B). Le cœur absorbant (40) a une partie à grammage élevé (41) dans le centre de la direction de la largeur de l'entrejambe (C) et des parties à faible grammage (42) d'un grammage inférieur à celui de ladite partie à grammage élevé (41) sur les deux côtés de la partie à grammage élevé. La partie à grammage élevé (41) a une partie centrale d'induction de plis (43) qui est configurée à partir d'une région de fente, de sillon ou sans fibre qui s'étend dans le sens longitudinal du cœur absorbant (40). Chaque partie à faible grammage a une partie latérale d'induction de plis (44) qui est configurée à partir d'une région sans fibre. Sur le côté abdominal (A) du cœur absorbant (40) dans le sens longitudinal, la partie centrale d'induction de plis (43) s'étend au-delà des extrémités des parties latérales d'induction de plis (44) et sur le côté de l'arrière (B) du cœur absorbant (40) dans le sens longitudinal, les parties latérales d'induction de plis (44) s'étendent au-delà de la partie centrale d'induction de plis (43).
