Abstract
(EN)
A diaper (1) includes, at least in an abdomen-side section (A), a first stretch area (40) and a second stretch area (45) in which the stretching stress is greater than that in the first stretch area (40). An outer-layer sheet (30) of an external body (3) includes an outer-layer fold-back section (32) that is folded back to the skin-facing-surface side. An outer-layer fold-back section (32b) in a back-side section (B) is bonded to the skin facing surface of an absorbent body (2), at the end thereof closer to a crotch section (C). An outer-layer fold-back section (32a) in the abdomen-side section (A) includes a bonded section (50) at which the outer-layer fold-back section (32a) is bonded to a member opposite thereto, and a non-bonded section (53) that is located closer to the crotch section (C) than the bonded section (50) is and that is not bonded to a member opposite to the outer-layer fold-back section (32). The end of the bonded section (50) closer to the crotch section (C) is located in the first stretch area (40).

L'invention concerne une couche (1) comprenant, au moins dans une section côté abdomen (A), une première zone d'étirement (40) et une deuxième zone d'étirement (45) dans laquelle la contrainte d'étirement est supérieure à celle dans la première zone d'étirement (40). Une feuille externe de couche (30) d'un corps externe (3) comprend une section de repli de couche externe (32) qui est repliée vers le côté de surface faisant face à la peau. Une section de repli de couche externe (32b) dans une section côté arrière (B) est liée à la surface faisant face à la peau d'un corps absorbant (2), en son extrémité plus proche d'une section d'entrejambe (C). Une section de repli de couche externe (32a) dans la section côté abdomen (A) comprend une section liée (50) au niveau de laquelle la section de repli de couche externe (32a) est liée à un élément opposé à celui-ci et une section non liée (53) qui est située plus près de la section d'entrejambe (C) que la section liée (50) ne l'est et qui n'est pas liée à un élément opposé à la section de repli de couche externe (32). L'extrémité de la section liée (50) plus proche de la section d'entrejambe (C) est située dans la première zone d'étirement (40).
