Further, since the absorber 85 is thinned in the guide groove 95, the step between the lower end portion of the pocket forming portion 20 positioned above the absorber 85 is reduced, and thus excrement flows into the pocket space S more. It can be said that it becomes easy.

By being located in the pocket 30, it is excellent in leakproofness and can prevent exudation of such soft stool. Moreover, the leak-proof sheet 86 has a dimension in the lateral direction X that is larger than the dimension in the lateral direction X of the pocket opening of the pocket 30. Therefore, exudation of excrement entering the pocket space S from the pocket opening can be effectively prevented.

Abstract

La présente invention concerne une couche jetable comprenant une poche qui reçoit et conserve les excréments qui se déplacent vers le côté d'ouverture vers la taille dans une région de taille arrière, et à l'aide de laquelle il est possible d'empêcher que les excréments n'entrent en contact avec la peau de l'utilisateur. Dans cette couche jetable (10), une région (14) de taille arrière comprend : une région en forme de bande (région de contact avec la peau) (23), qui est située sur le côté de la surface opposée à la peau, et qui s'étend le long de la direction latérale (X) ; et une section (20) formant une poche, comprenant une poche (30) qui est située sur le côté de la surface qui n'est pas opposée à la peau, et qui s'oppose à la région (23) en forme de bande dans la direction allant de l'avant vers l'arrière dans une section centrale de la direction latérale (X). La section (20) formant une poche comprend : des sections (45) de fixation des côtés, qui sont fixées à la région (23) en forme de bande ; une région (42) à l'intérieur de la poche, qui s'étend vers le haut à partir d'une section reliée à la région (23) en forme de bande entre les deux sections (45) de fixation des côtés ; et une région (43) extérieure de la poche, qui s'oppose à la région (42) à l'intérieur de la poche dans la direction allant de l'avant vers l'arrière par l'intermédiaire d'une section de flexion (33) s'étendant le long de la direction latérale (X) et qui s'étend vers le côté de la région d'entrejambe (15). La région (23) en forme de bande peut subir une expansion/une contraction élastiques dans la direction latérale (X), et, entre les deux sections (45) de fixation des côtés, la vitesse de contraction de la région (23) en forme de bande est supérieure à la vitesse de contraction de la région (43) extérieure de la poche.
