Abstract

La présente invention concerne une couche jetable : qui peut être ajustée au corps d'un porteur avec une facilité relative par pliage d'une région de taille avant du corps de couche principal fermement vers l'extérieur ; et dont les emplacements fléchis n'ondulent pas lorsque la couche est portée. Un noyau absorbant (22) a une section de guide de pliage (24) qui s'étend dans la direction de l'axe horizontal (Q) dans la région de taille avant (11), et des régions latérales élastiques (43), qui peuvent s'étendre et se contracter le long des deux côtés (30, 31), sont formées sur les deux côtés (30, 31) d'une région d'entrejambe (13). Des sections de faible élasticité (46) ayant un faible taux de contraction comparé aux autres emplacements (sections très élastiques) (47), qui s'étendent vers la région de taille arrière (12) depuis la proximité du bord arrière (24a) de la section de guide de pliage (24), sont formées sur les régions latérales élastiques (43).
