  • Patent number: 8584909
    Abstract: A dispensing tap for beverages that comprises an actuator and a valve housing. A conical spring washer is joined and/or sealed to an actuator base to form the actuator. The actuator is then inserted into the valve housing to form the dispensing tap for attachment to a container containing a liquid. In use, a force is exerted on the conical spring washer to actuate the actuator base within the valve housing and thereby create an opening and/or passageway in the dispensing tap. Once opened and as the force is maintained, the liquid in the container can flow through the opening or passageway for dispensing the liquid out the dispensing tap. Upon releasing the force, the conical spring washer returns back to its original position. This movement of the conical spring washer causes the actuator base to move in the reverse direction within the valve housing thereby closing the opening and/or eliminating the passageway in the dispensing tap.
