Spill-proof cap for beverage containers

Abstract

A spill-proof cap or lid for a standard beverage container, such as a soft drink, water and other liquid bottle, includes a housing which is configured to fit over the container opening. The housing includes top and bottom, each of which includes a recess. A spout is mounted in the top recess and is pivotable between open and closed positions. A flow control section extends generally vertically in the bottom recess for receiving a flow control member. The flow control member is removably positioned in the flow control section and includes a flow control valve and an air intake valve. The spout includes at least one passageway which is in fluid communication with the bottom recess through a passageway extending between the top and bottom of the housing. In use, the cap is substituted for the conventional cap or lid that the typical soft drink, water or other liquid bottle is equipped with. When the spout is flipped upwardly in the open position, and a suction pressure is applied, the liquid from inside the bottle flows out through the spout passageway. When the suction pressure on the spout is released, the flow of liquid stops. Upon flipping the spout to the horizontal closed position, any risk of spilling or dripping is avoided.
