Abstract

L'invention concerne un sous-vêtement jetable, lequel s'adapte facilement au corps d'un utilisateur, et lequel permet de supprimer les glissements vers le bas. Plus spécifiquement, une couche (1) de type culotte comporte: un élément (11) côté ventre; un élément (12) côté dos; un élément fourche (5) qui relie les deux éléments précédents; des parties ouvertures (13, 14) pour les jambes, formées par assemblage entre elles de parties d'extrémité (15a, 15b) gauches et de parties d'extrémité (15c, 15d) droites de l'élément (11) côté ventre et de l'élément (12) côté dos, de façon à être entourées par l'élément (11) côté ventre, l'élément (12) côté dos et l'élément fourche (5); des corps élastiques (21, 21a, 21b) entourant le tronc, lesquels s'étendent vers la droite et vers la gauche de l'élément (11) côté ventre et de l'élément (12) côté dos, et lesquels sont positionnés dans une région située au-dessous parties hanches (4, 4a, 4b) le long de chaque extrémité supérieure des éléments (11, 12) et au-dessus des parties ouvertures (13, 14) pour les jambes. Au moins une partie des corps élastiques (21, 21a, 21b) entourant le tronc se caractérisent en ce que leur force de serrage s'affaiblit peu à peu à partir du côté parties hanches (4, 4a, 4b) en direction du côté parties ouvertures (13, 14) pour les jambes droite et gauche.
