Patent Images
1. A liquid reception device comprising:
- (a) a liquid receiving layer having a target zone;
(b) a peripheral zone located within or outside said liquid receiving layer;
(c) mechanical transport means located partially within said target zone and adapted for liquid communication with said peripheral zone; and
comprising;
(i) at least one tube having at least one sealed opening within said target zone;
(ii) suction means comprising a compressed bulb containing a superabsorbent connected to said at least one tube for drawing said liquid through said at least one tube from said target zone to said peripheral zone; and
(iii) means for opening said at least one sealed opening activated by contact with said liquid thereby causing said suction means to draw said liquid.

Abstract
A liquid reception device as a component, for example, of a personal care product such as a disposable diaper, an incontinent garment, or for other applications such as, for example, an industrial soaker pad or the like. The device includes liquid activated means to move a liquid insult from a target zone to a peripheral zone. The liquid activated transport means operated mechanically by suction created by compression or vacuum or by physical movement of a liquid container from the target zone to the peripheral zone. The disclosed device provides increased use of available liquid handling capacity.
