Absorbent devices and precursors therefor

Abstract From the Canadian patent

An absorbent device comprises an absorbent layer having an apertured contoured polymer film attached to one surface which 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 a 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.
