A bicomponent material which allows liquids to pass in a first direction, but substantially prevents the liquids from passing in the opposite direction, is disclosed. The material also exposes any gases attempting to pass in the direction opposite to that of the liquid transmission to an odor control lamina. The material is especially suitable for use with articles which deal with bodily fluids and the gases generated therefrom.

A disposable absorbent article for collecting liquids discharged from a source and substantially containing malodors generated by the collected liquids, said article comprising: (a) an absorbent core means for absorbing liquids, said core means having a first face and a second face opposed thereto; (b) a liquid impermeable backsheet overlaying said first opposed face of said core means; (c) a liquid permeable topsheet overlaying said second opposed face of said core means; and (d) a bicomponent film laminate disposed between said topsheet and said backsheet, said laminate comprising a first polymeric lamina exhibiting a pattern of discrete apertures therein, said first lamina having an exterior face and an interior face opposed thereto; said laminate further comprising a second active lamina comprising an odor control means, said second lamina having a first face adjacent said interior face of said first lamina and a second face opposed thereto, said second face of said second lamina being directionally oriented toward said core means, said second lamina also exhibiting a pattern of discrete apertures substantially coinciding with said discrete apertures of said first lamina, whereby said laminate includes means for permitting liquids deposited on said exterior face of said first lamina to pass through said discrete apertures in said laminate to said core means without substantially wetting said second lamina, said laminate also including means substantially preventing gaseous malodors generated by the absorbed liquids from passing through said laminate in a direction opposite to the direction of transmission of deposited liquids without substantial exposure of the gaseous malodors to said second face of said second lamina.
