Abstract

L'invention porte sur un article jetable à porter qui, par manipulation relativement simple, positionne une région de taille avant vers le bas d'une manière telle que l'abdomen d'un porteur est exposé, et peut être fixé fermement au corps du porteur dans un état de suspension. Un système de fixation destiné à relier les sections de bord sur les deux côtés des régions de taille avant et arrière (12, 13) comprend : un premier élément de fixation (17) disposé sur la surface tournée vers la peau d'une paire de languettes de fermeture à ruban (15, 16) qui s'étendent des bords sur les deux côtés (13a, 13b) de la région de taille arrière (13) à l'extérieur dans la direction d'un axe horizontal (Q) ; et un second élément de fixation (18) positionné presque parallèlement au premier élément de fixation (17) sur la surface non tournée vers la peau de la région de taille avant (12). Plusieurs sections de guidage courbes (24, 25, 26), qui s'étendent dans la direction de l'axe horizontal (Q) dans la région de taille avant (12) et une région d'entrejambe (14), sont formées dans un noyau absorbant (22) d'un corps principal (11) de couche-culotte.
