Benefits of technology

The patent describes a device that can be added to existing food storage packages to improve their vacuum-sealing ability. By periodically checking the package, any air or moisture that may enter through the package's sidewalls can be removed, ensuring the package remains in a vacuum state and maintaining its freshness. This device can improve the storage and preservation of frozen food, making it easier to retrieve and reseal the package.

Problems solved by technology

Compressed foam valve cannot be readily opened by manual compression on the sealed bag but can stay closed at low vacuum.
Our test indicated that the zipper strips of food packages are incapable of holding high vacuum and only heat sealed food bags can hold high vacuum.

Embodiment Construction

[0024]FIG. 1 Illustrates a box shape compressed foam sponge valve 100 as described in the inventor's U.S. Pat. No. 8,056,471; (A) front view, (B) top isometric view and (C) sectional view 1C-1Ccut from (A). Rectangular valve box housing 101 is open at the front and has a central tubular protrusion 104 with central opening 105 in the bottom and contains compressed closed cell foam block 102. The degree of compression determines the magnitude of closing force of the valve by controlling the expansive force of the block. The rectangular double-sided amorphous viscid adhesive insert 103 with a central bore is bonded to the inferior rectangular surface of the valve box 101. The adhesive insert 103 has two main roles; (1) to bond two elements, the valve 101 and a food package 501 as show in FIG. 5 and (2) to fill in micro holes and grooves on what appears to be flat surface of the rigid valve housing 101. If they are not filled with amorphous viscid adhesive material, micro tracts may be ...

Abstract

Universal air removal port can be installed on factory sealed frozen food bags or any new plastic food bags. The port comprises of a flat disk or compressed foam check valve, air sieve and double-sided adhesive inserts to bond two elements. A hole is created on one-side wall of food bag. The check valve is bonded to the exterior hole and the air sieve to the interior hole. Valve restricts air flows to outflows from the sealed bag. Multiple openings of air sieve prevent blocking of valve inlet by foods or bag film. Its flat top plate reinforces bonding of bag film and the valve. Amorphous viscid adhesive inserts fill micro holes and grooves on valve surface, eliminating formation of micro tracts and loss of vacuum. The universal air removal port can be removed from empty bag and reused on a new food bag.

Field of the Invention[0006]This invention relates to a universal air removal port. More specifically the air removal port that can be installed on any existing food bags, as the word, “universal” implies, such as factory packed frozen food bags with or without resealing zipper strips, new empty food bags with or without resealing zipper strips. In case of food bags without resealing zipper strips, the open ends of the bags are sealed by an...
