Patent

CA 2103477

Here is disclosed a topsheet for use in body fluid absorptive goods so improved to achieve an effective shape-stabilization of liquid passages formed in the topsheet. To this end, a topsheet 2 comprises an upper sheet 7 having a skin-contacting area 14 and liquid passages 13 and a lower sheet 8 underlying the upper sheet 7. The lower sheet 8 is welded to the upper sheet 7 around lower openings 12 of the respective liquid passages 13 so as to restrict deformation of these passages which would otherwise possibly occur.

La présente invention vise une feuille extérieure de matériaux utilisés dans la fabrication des produits absorbants pour fluides biologiques, améliorée de telle manière que les cavités pour liquides que cette feuille recouvre conservent leur forme après l'absorption des liquides. Dans ce but, la feuille supérieure (2) se compose d'une première feuille (7) dont certaines parties entrent en contact avec la peau (14) et de cavités pour liquides (13), et d'une feuille inférieure (8) mise en place sous la première feuille (7). La feuille inférieure (8) est soudée à la première feuille (7) à la base des ouvertures (12) de chaque cavité pour liquides (13) de manière à réduire le plus possible la déformation de ces cavités.
