PRESSURE RESPONSIVE VALVE

摘要

The present invention (Fig. 6) relates to a pressure responsive valve for use within a self-contained cooling apparatus to be placed in a beverage container, with the self-contained cooling apparatus comprising multiple chambers for separating vaporizable liquid and sorbent or desiccant. This invention provides a simplified method of using the pressure differential to activate the valve, thus solving the long felt need to activate a self-contained cooling apparatus within a sealed and pressurized beverage container. When the beverage container is opened, the pressure differential will cause the valve to become activated, to switch from the closed position to the open position, thus permitting the self-contained cooling apparatus to operate as designed.
