Abstract

L'invention concerne un article absorbant qui comprend : une première partie extérieure qui forme un panneau avant; une seconde partie extérieure qui forme un panneau arrière; et un corps principal absorbant qui, à des parties d'extrémité dans le sens avant-arrière, comprend des parties de liaison qui chevauchent la première partie extérieure et la seconde partie extérieure. La première partie extérieure et la seconde partie extérieure forment une partie taille lorsque des parties d'extrémité de direction de taille respectives de celles-ci sont reliées entre elles au niveau de parties de jonction. Au moins une partie extérieure parmi la première partie extérieure et la seconde partie extérieure est positionnée davantage vers l'intérieur, c'est-à-dire, plus près de la peau d'un utilisateur, que le corps principal absorbant, et, dans une région dans laquelle une partie de liaison chevauche une partie extérieure qui est disposée sur l'intérieur, il y a au moins une poche qui a une extrémité ouverte qui s'ouvre vers l'entrejambe. La ou les poches sont suffisamment grandes pour loger une masse qui est formée lorsque la première partie extérieure et la seconde partie extérieure ont été séparées au niveau des parties de jonction et que tout sauf la poche a été enroulé dans la direction avant-arrière.
