Abstract

A vacuum storage bag not requiring the use of an external vacuum source. With a resilient sponge compressible polymeric material mass such as a rectangular sheet or any shape of sufficient thickness that is an integral part of an opposing wall of storage bag, a vacuum can be produced by compressing sponge within this sealable bag. The sponge being an integral part of inner bag wall will not shift and interfere with a valve or bag closure. By compressing the resilient sponge material/resilient mass flattening or rolling contents along with a food product/dry goods or any other material that is to be stored, and forcing the air volume out of the sealable bag, utilizing one of the many valved zipper closures or pinch rail valve closure systems expelling the air. Any residual air not exhausted from bag will mostly be trapped within sponge material when sponge expands.

Claims
