Abstract

La présente invention concerne une couche jetable qui a une ouverture de taille qui est facilement expansée et qui est rigidement maintenue sur le corps. La couche jetable comporte une paire de ceintures de taille, et les ceintures de taille sont assemblées à un corps de couche par l'intermédiaire de lignes d'assemblage qui approchent une ligne centrale verticale depuis le côté d'ouverture de jambe vers le côté d'ouverture de taille dans les régions de taille avant et arrière. Au moins une des régions de taille avant et arrière comporte une région supérieure positionnée au niveau du côté d'ouverture de taille et une région inférieure positionnée au niveau du coté d'ouverture de jambe, et, dans un état dans lequel les ceintures de taille sont contractées, la dimension de longueur de la région inférieure dans la direction latérale devient supérieure à celle de la région supérieure dans la direction latérale.
