Disposable diaper with reception, distribution-storage and anti-leakage zones within the absorbent core

Abstract

A disposable diaper is described in which the absorbent core's material is distributed in such a way that three zones are made inside of it" one of liquid reception, a zone of distribution-storage, and finally an anti-leakage zone. The reception zone is placed where generally the user discharges urine while using the diaper. This zone is less dense and has a lower specific gravity than the distribution-storage zone that fully surrounds it, in such way that when liquid flows in the reception zone it is immediately absorbed and flows towards the distribution-storage zone, which will distribute the liquid to every zone of the diaper and there it will remain until the diaper is disposed, since when liquid reaches the anti-leakage zone fluid flow is drastically stopped because this zone has lower density than the distribution-storage zone and the liquid will not flow towards it due to the increased size of the capillary radius. This anti-leakage zone surrounds all the distribution-storage zone, shaping all the periphery of the absorbent core, so that as is does not permit liquid flow towards it, it will remain dry and it will completely avoid leakage in any of the zones of the diaper.
