Abstract
An absorbent device which comprises an absorbent layer having an apertured contoured polymer film attached to a surface, wherein this surface is provided with a plurality of depressions which communicate directly with the apertures in the film. The device may be produced by separating the polymer film and a carrier material which have been formed into a laminate having impressed therein raised areas defining, for example, the strands of net and depressed areas such that upon separation the depressed areas of the film remain attached together with associated portions of the attached absorbent, to the carrier, leaving the raised areas attached to the remainder of the absorbent.
Claims20
An absorbent device which comprises a contoured polymer film having opposed sides, an absorbent layer having a surface thereof attached to one said side and a carrier material attached to the other said side, said carrier material and said contoured polymer film forming a laminate having impressed in said carrier material and contoured polymer film a pattern of raised areas and depressed areas therebetween, said contoured polymer film and said carrier material being attached to each other such that upon separation of one from the other the depressed areas of the contoured polymer film remain adhered to the carrier material leaving behind on said surface of said absorbent layer an apertured film comprising the raised areas of said contoured polymer film, said surface having a plurality of depressions which communicate directly with the apertures in said apertured film, said depressions being free of film.
