Claim Text:
1. A non-spill valve for a neck and spout of a liquid container, comprising: a flexible tube which is open at a first end and upstands from an apertured support of which an aperture is in registry with and of the same size as the first open end of the tube, the support having a shape which is complementary with an interior of the neck and spout so that it forms a partition in the neck and spout of the container and permits the passage of liquid from the aperture in the support into the tube interior, wherein a second end of the tube directed towards a mouth of the neck or spout is closed and an incision separates a side wall portion of the tube from the second end and the adjoining portions of the side wall portions of the tube, wherein the incision continues along the side wall portion up to a distance short of the support to define a flap which is substantially perpendicular to the support and which is hinged to a remaining portion of the side wall portion, and wherein the flap lies against the second end and the adjoining portions of the side wall portions of the tube from which it is severed, and wherein the flap can flex under suction applied to the neck and spout and thereby permit liquid to reach from the tube interior to a mouth of the neck or spout.
