Abstract

La présente invention concerne un article vestimentaire jetable qui comprend une patte de fixation et qui est facile à maintenir. Des première et seconde zones de taille (13, 14) de l'article vestimentaire jetable (10) peuvent s'étendre et se contracter élastiquement dans la direction horizontale (X). La patte de fixation (20) présente une direction d'épaisseur (Z), une section proximale (21) fixée à la surface extérieure de la première zone de taille (14) et une section distale (22) faisant face à la section proximale (21) dans la direction d'épaisseur (Z). La section proximale (21) et la section distale (22) sont fixées temporairement l'une à l'autre par l'intermédiaire de sections de fixation temporaire (65, 66) positionnées davantage sur l'intérieur dans la direction horizontale (X) qu'une zone de joint de section latérale (23). La section distale (22) comporte une zone de fixation (68) et une section de maintien (63) qui s'étend à partir de la section de fixation temporaire (65) en direction du côté de la zone de joint de section latérale (23). Lorsque les première et seconde zones de taille (13, 14) sont dans un état contracté, la zone de joint de section latérale (23) s'incurve dans la direction horizontale (X), avec la première zone de taille (14) sur l'extérieur de celle-ci et, par conséquent, une partie de la section proximale (21) est également incurvée et la section de maintien (63) est éloignée de la section incurvée de la section proximale (21) et s'étend vers l'extérieur dans la direction horizontale (X).
