Abstract
A vacuum sealing appliance for lidded containers. A container is evacuated by placing a conventional container with a lid under a bell cover or by applying a special lid to an open container. An actuator assembly moves a valve to an sealed position and energizes an electrical vacuum pump. A vacuum switch and solenoid simultaneously terminate the operation of the vacuum pump and allow atmospheric pressure to be applied to the lid, thereby to seal the lid against the container.
