Abstract:
A pouring spout for a liquid container comprising a non-resilient, pliable plastic sheet defining one side of the pouring spout and movable towards and away from an opposite side of the pouring spout to close and open the pouring spout for dispensing liquid therethrough; said non-resilient, pliable plastic sheet being dimensioned such that when liquid is to be dispensed, the non-resilient, pliable plastic sheet is freely movable away from said opposite side by the liquid to permit the liquid to be dispensed, and when liquid is not being dispensed through the pouring spout, the non-resilient, pliable plastic sheet moves towards and into contact with said opposite side and adheres to said opposite side solely by surface tension of the liquid to produce a liquid dependent self-sealing action with respect to said pouring spout.
