Abstract

Dans la présente invention, une bande jetable (10) est disposée sur une surface externe d'une couche-culotte (1). La bande jetable (10) est conçue de telle sorte qu'une partie fixe (12), une partie d'extension (15) et une partie de fixation (18) sont agencées dans cet ordre le long d'une direction de longueur (X1) de la bande jetable (10), et sont pliées en trois couches dans cet ordre. La partie de fixation (18) et la partie d'extension (15) sont liées l'une à l'autre de manière pelable, et la partie d'extension et la partie fixe (12) sont également liées l'une à l'autre de manière pelable. La résistance à la traction à laquelle l'allongement de la partie de fixation (18) commence est supérieure à la résistance à la traction à laquelle commence l'allongement de la partie d'extension (15). La résistance à la traction à laquelle l'allongement de la partie d'extension (15) commence est inférieure ou égale à 6,5 N. La force de pelage entre la partie de fixation (18) et la partie d'extension (15) est inférieure ou égale à 4,0 N.
