Abstract

There is disclosed an improved stand-off for large vacuum compression storage bags made from a thermoplastic material such as polyethylene or other thermoplastic material and preferably made by extrusion. The stand-off includes a base having an aperture therein for alignment with the valve of the bag. The base further includes a plurality of ribs. The stand-off may include a variety of geometries provided that it is of sufficient length and width to cover the valve area. It may extend from one side of the bag to the other side of the bag or include variations thereof in size.

Description

RELATED APPLICATION

[0001] The present application claims benefit of U.S. Provisional Application Ser. No. 61 / 344,831 filed Oct. 20, 2010 entitled “VACUUM COMPRESSION STORAGE BAGS”.FIELD OF INVENTION

[0002] The present invention relates to vacuum compression storage bags. More specifically, the invention is directed to large vacuum compression storage bags for clothing and other items which include a stand-off for optimizing the air flow and evacuation of air from the bag.BACKGROUND OF THE INVENTION

[0003] Vacuum compression storage bags are known in the art. For example, SPACE BAG® brand vacuum compression storage bags are commercially available for storage of clothing and other items. Such storage bags generally include a first side panel and a second side panel which side panels are sealed at the edges and the bottom forming the bag having an open top. These bags further include a re-closable closure mechanism near the top portion of the bag for opening and closing the bag. The bags fu...

Embodiment Construction

[0025]The present invention is directed to large vacuum compression storage bags which are simple and inexpensive to manufacture while providing substantially complete evacuation of air from the bag without the need for a complex and expensive valve and bag assembly. The storage bag of the invention includes a simple and inexpensive valve and an improved stand-off which provides for efficient evacuation of air from the storage bag after it is filled with the items, e.g. clothing, blankets and other material, to be stored and closed. The improved stand-off of the invention is preferably made by extrusion from a plastic material such as polyethylene. The stand-off is flexible and rigid, i.e. it has greater thickness than the storage bag walls. Other materials may also be used for the stand-off such as polypropylene, nylon or bioplastics.

[0026]Referring generally to FIGS. 5-8, large vacuum compression storage bags, e.g. in the range of about 18 inches by 20 inches to about 35 inches to...
