Liquid retaining absorbent structures consisting of a plurality of cells, each cell having an aperture to allow a liquid to enter the cell. The cell contains an expandable absorbent material and a valve member. As liquid enters the cell, the absorbent expands. When the amount of liquid is equivalent to the free volume of the cell the expanding absorbent causes the valve member to seal the aperture to isolate the liquid.
