Abstract

L'invention concerne une couche jetable facile à utiliser qui est équipée d'une ceinture, réduit l'anxiété concernant une fuite éventuelle d'excréments à travers une ouverture à la taille, et rassure une personne qui la porte. Une couche jetable (10) comporte : une direction devant-derrière (L) et une direction de largeur (W) qui sont orthogonales l'une à l'autre ; deux régions de tour de taille comprenant une région de tour de taille avant (S1) et une région de tour de taille arrière (S2), et une région d'entrejambe (S3) disposée entre lesdites deux régions de tour de taille ; une ceinture (80) qui est disposée dans au moins l'une des deux régions de tour de taille ; et une partie corps (11) qui comprend une partie centrale absorbante (31) et qui est formée d'un élément qui est disposé en une position plus près d'un côté surface non tournée vers la peau par rapport à la position de la ceinture. Un espace de réception (AS) est formé de façon s'ouvrir vers le côté de la région d'entrejambe (S3) de la ceinture sur le côté surface non tournée vers la peau. La ceinture (80) est conçue pour être disposée de manière à faire face à un côté surface tournée vers la peau (T1) de la couche jetable (10).
