Abstract

L'invention concerne un article pouvant être porté qui comprend une région de réception de déchets corporels qui a une capacité d'absorption de liquide, ne compromet pas la résistance à l'usure, et est capable de former un espace de réception de déchets corporels de taille relativement suffisante. Un absorbeur (25) d'un article pouvant être porté (10) comprend : une région de réception de déchets corporels (50) qui est isolée et présente une absorbabilité de liquide ; et une région périphérique d'absorption de liquide (51) qui est positionnée de façon à entourer la région de réception de déchets corporels (50). Après absorption du fluide corporel par l'absorbeur (25), la dimension d'épaisseur (D1) de la région de réception de déchets corporels (50) devient plus petite que les dimensions d'épaisseur (D2, D3) de la région périphérique. La différence des dimensions d'épaisseur entre la région de réception de déchets corporels (50) et la région périphérique (51) après absorption du fluide corporel par l'absorbeur (25) est supérieure à la différence des dimensions d'épaisseur entre la région de réception de déchets corporels (50) et la région périphérique (51) avant l'absorption du fluide corporel par l'absorbeur (25).
