Abstract

L'invention concerne une couche jetable qui est susceptible d'empêcher les excréments de suinter jusqu'à un côté ceinture et, par conséquent, de se fixer à la peau. Une couche jetable (10) comprend : un noyau absorbant (31) ; une feuille côté surface de peau (20) qui est située en une position plus proche d'un côté de surface faisant face à la peau, par rapport à la position du noyau absorbant ; et une ceinture (80) qui est située en une position, dans une région de sangle arrière, située plus près du côté de surface faisant face à la peau, par rapport à la position de la feuille côté surface de la peau et qui s'étend et se contracte dans la direction de la largeur. La ceinture comprend : une partie d'érection (85) qui est conçue pour pouvoir être érigée ; et une partie d'extrémité de base (84, 87) qui est jointe à la feuille côté surface de peau et qui comprend un bord d'extrémité de base pour servir de point de pivotement pour ériger la partie d'érection. Au moins une portion de la partie d'érection est pliée vers un côté arrière au niveau d'une ligne de pliage située sur un côté avant par rapport à la position de la partie d'extrémité de base et est conçue pour être érigée de la partie d'extrémité de base vers le côté de surface faisant face à la peau. La partie d'extrémité de base comporte en son sein une couche de film imperméable aux liquides (813).
