Abstract:
(EN) The purpose of the present invention to disperse body fluid discharged onto the widthwise center of an absorber so that the absorbent capacity of the absorber can be efficiently used. The disposable diaper (10) includes: an absorber (40) that has an absorbent core (40a) and a core wrap (40b); and a top sheet (50) that is disposed on a skin facing side of the absorber. The absorber includes: a center region (45) that is disposed in the widthwise center of the absorber and comprises a center absorbent layer (401); and side regions (45) disposed outside the center region in the width direction and comprising the center absorbent layer (401), a first side absorbent layer (402), and a second side absorbent layer (402). The top sheet is disposed spanning across the skin facing side of the center region and the skin facing side of the side regions. The core wrap has a density that is higher than the density of the top sheet. The side regions have a density that is higher than the density of the center region.
(FR) L'invention concerne la dispersion d’un fluide corporel déchargé sur le centre dans le sens de la largeur d'un absorbeur, de telle sorte que la capacité absorbante de l'absorbeur puisse être efficacement utilisée. La couche jetable (10) comprend : un absorbeur (40) qui a un noyau absorbant (40a) et une enveloppe centrale (40b) ; et une feuille supérieure (50) qui est disposée sur un côté de l'absorbeur faisant face à la peau. L'absorbeur comprend : une région centrale (45) qui est disposée dans le centre de la largeur de l'absorbeur et comprend une couche absorbante centrale (401) ; et des régions latérales (45) disposées à l'extérieur de la région centrale dans la direction de la largeur et comprenant la couche absorbante centrale (401), une première couche absorbante latérale (402) et une seconde couche absorbante latérale (402). La feuille supérieure est disposée sur toute la longueur du côté faisant face à la peau de la région centrale et du côté faisant face à la peau des régions latérales. L'enveloppe centrale a une densité qui est supérieure à la densité de la feuille supérieure. Les régions latérales ont une densité qui est supérieure à la densité de la région centrale.
(JA) 吸収体の幅方向の中央に排出された体液を拡散し、吸収体の吸収性能を有効活用する。使い捨ておむつ(10)は、吸収コア(40a)及びコアラップ(40b)を有する吸収体(40)と、吸収体の肌対向面側に配置されたトップシート(50)と、を備える。吸収体は、吸収体の幅方向の中央に配置され、かつ中央吸収層(401)を有する中央領域(45)と、中央領域の幅方向の両外側に配置され、かつ中央吸収層(401)、第1側部吸収層(402)及び第2側部吸収層(402)を有する側部領域(45)と、を備える。トップシートは、中央領域の肌対向面側と側部領域の肌対向面側を跨がって配置されている。コアラップの密度は、トップシートの密度よりも高い。側部領域の密度は、中央領域の密度よりも高い。
