Abstract

L'invention fournit un article absorbant qui permet de faciliter la séparation d'ailettes au niveau d'une partie guide de déchirure, lorsqu'il est retiré d'un sous-vêtement. Cet article absorbant (1) est équipé : d'une direction avant/arrière (L) ; d'une direction latérale (W) perpendiculaire à la direction avant/arrière (L) ; d'une partie corps principale (2) possédant un corps absorbant (30) ; et d'une paire de première et de seconde ailette (41, 42) qui se prolonge côté externe dans la direction latérale à partir de la partie corps principale (2), et qui se chevauche de manière réciproque dans un état de port sur un sous-vêtement. La première ailette (41) possède la partie guide de déchirure (80) se prolongeant dans la direction avant/arrière (L). La première ailette (41) possède également une partie rétrécissement (70) en forme de relief vers le centre de la direction avant/arrière (L). La partie guide de déchirure (80) est agencée dans une région de la partie rétrécissement (70). La première ailette (41) possède une région relief (72) en forme de relief vers le côté externe à partir du centre de la direction avant/arrière (L) de la première ailette, côté interne de la direction latérale par rapport à la région de la partie rétrécissement (70).
