Abstract

　L'objet de la présente invention est de mettre au point un article absorbant qui s'adapte bien à la zone de l'entrejambe de l'utilisateur et permet à un absorbeur d'absorber des fluides corporels rapidement et efficacement.　La présente invention concerne un article absorbant qui comprend une seconde feuille (3) pliée. La seconde feuille (3) pliée comprend une partie de référence placée sur un côté feuille supérieure (2), et une première zone et/ou une deuxième zone qui s'étendent respectivement à partir des extrémités de ladite partie de référence. Ces zones ont chacune un nombre p de lignes de pliage de parties saillantes (p étant un nombre entier supérieur ou égal à 1), et un nombre q de lignes de pliage de parties en creux (q étant un nombre entier supérieur ou égal à 0). Dans la seconde feuille (3) pliée, la partie de référence et au moins une zone divisée de pliage de parties saillantes adjacente à ladite ligne de pliage de parties saillantes, vue en plan, s'étendent dans le sens de la largeur sur une ligne centrale s'étendant dans le sens de la longueur de l'article absorbant, et s'étendent également dans le sens de la longueur sur une ligne centrale s'étendant dans le sens de la largeur de l'article absorbant.
