Vacuum Storage Bag

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.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to an extremely simple and economical vacuum storage bag which does not require the use of an external vacuum source. This simple system can replace many off-the-shelf freezer and storage bags such as Ziploc, Glad, Hefty and independent freezer and standard storage bags as well as those by The FoodSaver, Weston or Nesco vacuum appliances and other similar units. It is much more economical and more likely to be purchased by everyday shoppers without investing in expensive vacuum equipment and specialized vacuum bags needed to use such equipment. The new invention discloses a resilient compressible polymeric material that may be an integral part of one of the bag walls or an insert of a resilient compressible polymeric material.2. Description of the Prior Art[0002]There are presently a wide variety of bags and storage systems in which food and other materials can be stored indefinitely. Many of the...

AI Technical Summary

Benefits of technology

The present invention is a vacuum storage bag that is simple and economical without the need for an external vacuum source. It can remove air and create a vacuum inside the bag using a sponge material or a compressible polymeric material inserted into the bag. The bag can be used for storing various food products or medical substances by compressing the sponge material and forcing the air out of the bag. This creates a vacuum that helps keep the contents of the bag fresh and dry. The invention provides a convenient and affordable solution for storing goods outside the presence of air.

Problems solved by technology

Expensive and cumbersome appliances along with costly vacuum bags are what make this patent insufficient as an answer when an economical and simple bag system is desired.

Those bags are also very costly and not available in many local store even if you own the vacuum / hot sealer.

This prior art is very difficult to make and isn't very practical or cost effective and hasn't been seen as a large seller in the market.

U.S. Pat. No. 6,231,236 discloses a resealable food bag with one way valve but still doesn't resolve the problem of air left in bag.

As quoted from the patent, “at least partial exhaustion of gases is desirable.” Because this prior art does not offer a means of removing air from the storage area, it does not eliminate freeze(burn for sensitive food products.
