Beverage dispenser having an airtight valve and seal

US-7854336-B2

Abstract

A beverage dispenser includes a container defining a container volume, and a substantially spill-proof cap, having a suction portion and an aperture on top of the suction portion, coupled to the container. A valve with a slit is inserted between the container and cap so that the slit is placed beneath the aperture of the cap. A pressure sensitive seal is placed on top of the aperture of the cap, so that a vacuum is created between the cap and the beverage inside the container. The slit is formed so that the beverage will flow through the slit of the valve and thus out of the aperture of the cap only if a suction force is applied on the suction portion of the cap 20.
