ABSTRACT:
A container is provided for storing items in a vacuum state. The container includes a receptacle with associated lid. A lever and clamp act together as a toggle to exert a relatively high closure force on the lid. The container includes a vacuum pump, preferably within a base of the container. A switch is provided to activate and deactivate the pump which is activated by the lever when the lever is pivoted to a closed position. A sensor is optionally also provided to shut off the pump when a sufficiently low pressure is reached. The lid includes a bleed port which is closed by the clamp when the lid is closed. When the lever and clamp are pivoted to an open position, this bleed port is opened so that pressure equalization occurs and the lid can be easily opened without fighting atmospheric pressure forces acting on the lid.
