Abstract:

A vacuum sealed canister unit which includes two parallel integrally constructed interconnected cylinders. A large cylinder defines a canister for storing food items and has a wide top opening with removable cover which can be sealed in place. The vacuum is released by a valve mechanism incorporated in the cover and handle of the large cylinder. The storage container is connected to a vacuum pump chamber by a passageway with a one-way check valve on the pump side. The arrangement of the vacuum pump shaft allows outside air pressure on the top side of the pump assembly shaft to be equalized and the pump handle to be stored in a down stroke position after pumping is complete. To operate, one places the thumb over a hole in the handle and depresses the handle. Space above a piston at the base of the handle shaft expands, drawing a vacuum in the storage container as air is drawn through the connecting passage between the cylinder. Upon raising the handle, the check valve closes to maintain the vacuum in the storage container.
