ABSTRACT:
A liquid dispensing container is provided with a pressure controlled flexible outlet which is opened and closed by applying and releasing pressure on a flexible area in the cover of the container above the level of the liquid and opposite the flexible outlet of the cover. An increase of pressure within the container by pressure on the flexible area causes automatic opening of a resilient conduit in the outlet permitting liquid to pass therethrough while a decrease of pressure in the container causes the resilient conduit to close and seal the container. A collection spout surrounds the resilient conduit and any dripping of liquid occurring when the contents of the container are being dispensed is collected in the spout and forced back into the container through a valve controlled orifice when pressure on the flexible area of the container is released.
