20120027323 | One Way Valve For Evacuating Air From Food Storage Bags - A one way valve for exhaling or evacuating air from containers, such as storage bags for preserving food and other items. The one way valve device is attached or sealed airtight to the body of the bag's outer surface wherein the one way valve is centrally positioned over a hole created on the surface of the bag. The hole forms a passage for the air to be evacuated from the interior of the bag to be led to the one way valve device. The one way valve device is made of a composition that remembers its original form, the form of the device having at least two component arms that meet with a sealing male and female format that separates and opens to allow any and all of the air from the interior of the bag to be released through the use of human applied pressure against the bag flexible structure, thereby evacuating the air from the interior of the bag. Upon release of the applied pressure the at least two component or component arms close and seal the bag preventing any additional air from reentering the bag through the one way valve device and thereby protecting the bag's contents from the destruction of its food contents or any other kind of stored contents for which air has a harming effect on it. | 02-02-2012 |
