Abstract
This relates to the hot packing of products such as food within cans. In order to permit the use of less strength cans than heretofore considered practicable, it has been necessary prior to the closing of such hot packed cans to introduce a pressurizing media such as liquid nitrogen being preferred. It is here proposed to so apply the closing end unit to the filled can so as to permit the end unit to function as a piston and to effect a pumping action when it is applied so as to permit the internal pressurization of the newly filled can without requiring any additive.
