ABSTRACT:
A self-closing valve for use with a bottle which includes a body having a neck with an opening therein at one end, and a moveable base at the other, is provided. In general, the valve comprises a stopper for selective location in the opening of the neck of the bottle, and an elongate actuating arm for moving the stopper. One end of the elongate arm is connected to the base of the bottle, while the stopper is located at the opposite end. Means are provided for allowing the base of the bottle to move with respect to the body. Pressure on the base of the bottle thus causes upward movement of the elongate arm, which movement causes the stopper to be pressed outwardly from the opening in the neck of the bottle, thus allowing fluid to flow from the bottle. Biasing means cause the base of the bottle to return to its natural state upon removal of the pressure, which simultaneously causes the stopper to be retracted into the neck of the bottle, stopping fluid flow.
