Abstract
An improved home dispenser of carbonated beverages is disclosed, together with a novel actuator valve mechanism. The valve mechanism may be shifted from the non-dispensing to the dispensing mode with minimum of applied force by reason of the interaction between sealing gaskets carried by the valve stem and complemental gasket enveloping skirts formed within the valve, the skirts being calculated to be radially outwardly deformed by pressure applied by the gaskets.
