Patent ID: 6849065

Claim:
An absorbent article comprising a liquid removal system and a storage member, said liquid removal system which comprises an interface device, said interface device comprising a first zone and a second zone and having a porous membrane separating said first zone from said second zone, said second zone being activated to provide a lower pressure therein than said first zone so as to provide a suction, said porous membrane being capable of maintaining a suction in said second zone without permitting air from said first zone to pass through said membrane into said second zone when said membrane has been wetted with a first liquid; said suction being maintained until said membrane is contacted with a second liquid; and wherein said second liquid upon entering said first zone and contacting said porous membrane is removed from said first zone by said suction in said second zone by passing through said membrane into said second zone said first zone having a user facing surface, said second zone having a back surface, said user facing surface having a urine acquisition zone, said second zone being in liquid communication with said storage member wherein said storage member imbibes liquid from said liquid removal system by at least one of capillary suction and osmotic pressure, said storage member comprising a superabsorbent polymer, characterized in that said liquid removal system has a skin hydration value of less than 200 milligrams.
