Abstract

L'invention concerne un article absorbant qui est conçu pour s'ajuster le long du corps. Une section de guidage incurvée (80) comprend : une paire de sections de guidage incurvées avant (81), qui sont disposées au moins dans une zone d'ouverture excrétoire (ER) faisant face à l'ouverture d'excrétion de l'utilisateur, et qui s'étendent vers l'arrière à partir d'un emplacement espacé d'un bord d'extrémité avant (30F) d'un absorbeur (30) sur les deux côtés extérieurs à partir du centre dans le sens de la largeur W de l'absorbeur (30) ; et une section de guidage incurvée arrière (82), qui est disposée entre la paire de sections de guidage incurvées avant (81) et s'étend dans la direction avant/arrière (L) davantage vers l'arrière que la région d'ouverture excrétoire (ER). Un bord d'extrémité avant (82F) de la section de guidage incurvée arrière (82) est situé davantage vers l'arrière qu'un bord d'extrémité avant (81F) de la paire de sections de guidage incurvées avant (81). Des bords d'extrémité arrière (81R) de la paire de sections de guidage incurvées avant (81) sont situées davantage vers l'arrière que le bord d'extrémité avant (82F) de la section de guidage incurvée arrière (82), et davantage vers l'avant qu'un bord d'extrémité arrière (82R) de la section de guidage incurvée arrière (82).
