First Claim
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 liquid 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 for drawing said liquid through said at least one tube from said target zone to said peripheral zone; and
(iii) opening means for opening said at least one sealed opening activated by contact with said liquid thereby causing said suction means to draw said liquid from said target zone to said peripheral zone.

Abstract
A liquid reception device is disclosed 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 is 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.
