Abstract: front page image
(EN)Provided is an absorbent article comprising an absorbent (50) having cells (55), the periphery of each of which is surrounded by a joint (54) that joins a front sheet (51) and a rear sheet (52), and in which the front sheet (51) and the rear sheet (52) are not joined, and highly-absorbent polymer particles (53) contained in the cells (55). The joints (54) include weak joints (54b) which can be peeled with the expansive force of the highly-absorbent polymer particles (53) within adjoining cells (55), and strong joints (54a) which do not peel. Each cell is surrounded on the four sides by the vertical strong join line (58) and the horizontal strong join line (59), and at least three maximum expansion sections (55G) in which the joint between cells (55) within the section are only weak joints (54b) are arranged in the longitudinal direction LD. The surface area of the maximum expansion sections (55G) becomes greater towards the center in the longitudinal direction (LD) from front and rear edges of the absorbent (50).
(FR)L'invention concerne un article absorbant comprenant un absorbant (50) ayant des cellules (55), dont la périphérie de chacune est entourée par une jointure (54) qui relie une feuille avant (51) et une feuille arrière (52), et dans lequel la feuille avant (51) et la feuille arrière (52) ne sont pas jointes, et des particules polymères hautement absorbantes (53) contenues dans les cellules (55). Les jointures (54) comprennent des jointures faibles (54b) qui peuvent être arrachées par la force d'expansion des particules polymères hautement absorbantes (53) à l'intérieur de cellules adjacentes (55), et des jointures fortes (54a) qui ne sont pas arrachées. Chaque cellule est entourée sur les quatre côtés par la ligne de jonction forte verticale (58) et la ligne de jonction forte horizontale (59), et au moins trois sections d'expansion maximale (55G) dans lesquelles la jointure entre les cellules (55) à l'intérieur de la section ne sont que des jointures faibles (54b) disposées dans la direction longitudinale LD. La surface des sections d'expansion maximale (55G) devient plus grande vers le centre dans la direction longitudinale (LD) à partir des bords avant et arrière de l'absorbant (50).
