Abstract
(EN)
The purpose of the present disclosure is to provide an absorbent body having excellent fitting properties, wearability, and absorbability. The absorbent body of the present disclosure has the following configuration. An absorbent body (14) characterized by comprising a superabsorbent polymer-containing absorbent core (47) and an intermediate layer (43) in the thickness direction (T), wherein: in a crotch region (MA) and in the width direction (W), the absorbent body (14) is partitioned into an absorbent core overlapping region (C2OP) overlapping the absorbent core (47) in the thickness direction (T) and a pair of absorbent core non-overlapping regions (C2NP) that do not overlap the absorbent core (47) in the thickness direction (T) and are arranged at both ends of the absorbent core overlapping region (C2OP); the intermediate layer (43) includes, in the crotch region (MA), an intermediate layer overlapping part (43OP) and a pair of intermediate layer non-overlapping parts (43NP) respectively arranged in the absorbent core overlapping region (C2OP) and the pair of absorbent core non-overlapping regions (C2NP); and in the crotch region (MA), the average basis weight or thickness of each of the pair of intermediate layer non-overlapping parts (43NP) is smaller than the average basis weight or thickness of the intermediate layer overlapping part (43OP).

L'objectif de la présente invention est de fournir un corps absorbant présentant d'excellentes propriétés d'adaptation, de portabilité et d'absorbabilité. Le corps absorbant de la présente invention présente la configuration suivante. L'invention concerne un corps absorbant (14) caractérisé en ce qu'il comprend un noyau absorbant (47) contenant un polymère superabsorbant et une couche intermédiaire (43) dans une direction de l'épaisseur (T), où : dans une région d'entrejambe et dans la direction de la largeur (W), le corps absorbant (14) est divisé en une région (C2OP) de chevauchement de noyau absorbant chevauchant le noyau absorbant (47) dans la direction de l'épaisseur (T) et une paire de régions (C2NP) de non-chevauchement de noyau absorbant qui ne chevauchent pas le noyau absorbant (47) dans la direction de l'épaisseur (T) et qui sont disposées aux deux extrémités de la région (C2OP) de chevauchement de noyau absorbant; la couche intermédiaire (43) comprend, dans la région d'entrejambe (MA), une partie (43OP) de chevauchement de couche intermédiaire et une paire de parties (43NP) de non-chevauchement de couche intermédiaire disposées respectivement dans la région (C2OP) de chevauchement de noyau absorbant et la paire de régions (C2NP) de non-chevauchement de noyau absorbant; et dans la région d'entrejambe (MA), le poids ou l'épaisseur de base moyen(ne) de chacune de la paire de parties (43NP) de non-chevauchement de couche intermédiaire est inférieur(e) au poids ou à l'épaisseur de base moyen(ne) de la partie (43OP) de chevauchement de couche intermédiaire.
