Abstract
A pumping system that is incorporated into and made part of a flexible air tight bag of the interlocking seal variety. Currently, the practice is to squeeze the storage compartment of the bag to force out as much air as possible and then sealing the bag. The improved method provides a means of pumping out air and other gases after the bag is sealed. This method results in a more complete elimination of air and other gases in the storage compartment of the bag.
