ABSTRACT:
A portable vacuum apparatus comprises a vacuum chamber to be filled with lidded jars, bottles or other containers containing foodstuff or other products for the purpose of storing the contents under vacuum. The vacuum chamber is composed of a platform covered by a layer of a resilient material serving as a seal, and of a removable cover seated on the platform. The chamber is pipe-connected to an electrically operated vacuum pump and to an automatic valve connecting the chamber with the atmosphere in open state. To evacuate the chamber and the jars the valve is manually closed and the pump is started exhausting air from the chamber and the jars. The valve is adapted to open automatically as soon as the required vacuum has been reached and to interrupt the electric supply to the pump motor. The valve is designed to open a wide passageway to the chamber causing the air to rush in and to create a shock wave. The lids on the jars and containers are of the conventional kind provided with gaskets and are slightly lifted off their seats during evacuation and are firmly pressed onto the openings of the jars by this shock and thus closed under vacuum conditions.
