Valve Providing Resistant Seal and Air Expulsion in a Receptacle

Abstract

A multi-layer control device comprising an adhesive layer, a base layer provided over the underlayer of adhesive, a baffle layer having a resealable section and a remainder section. The resealable section is able to detach from the remainder section of the baffle layer. The base layer has an opening to allow the expulsion of air within a receptacle while maintaining a seal from the outside environment. The interaction between the base layer and the baffle layer generates static energy. A method for adhering a multi-layer control device to a receptacle and releasing air pressure is also provided.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims the benefit of U.S. Provisional Application No. 61 / 310,740 filed Mar. 5, 2010, which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to valves. More specifically, the present invention relates to valves that provide a hermetic or water resistant seal but allow for the release of air pressure.BACKGROUND OF THE INVENTION[0003]A common problem with consumer or industrial packaging is excess air inside the receptacle. Often, it is desirable for a receptacle to provide a dry environment as well as to allow for air expulsion during package distribution, so that packages can be shipped flat and more packages can be fit within the trailer or rail car. In order to provide such an environment for a product, receptacles often times have small perforations, and must be kept in a dry environment in order to avoid water and moisture from entering the receptacle ...

AI Technical Summary

Benefits of technology

[0013]In accordance with a further embodiment of the present invention, a permeable layer of material is provided over the under layer of adhesive covering an opening in the adhesive layer. This additional layer would allow particulates to remain inside the interior of the receptacle while keeping liquids and unwanted contaminants on the exterior of the container from entering the interior of the receptacle.

[0014]In accordance with another embodiment of the present invention, a possible method for attaching a multi-layer control device to a receptacle and releasing air pressure from the receptacle is provided. By applying pressure to the receptacle, air flows through the opening in the base layer and then navigates its way out of the perforations in the baffle layer portion. The resealable section of the baffle layer unhinges from the base layer and separates from the remainder section of the baffle layer in order to facilitate the flow of air out of the interior of the receptacle.

[0016]In accordance with another embodiment a multi-layer control device having a continuous top layer and a layer of flexible material capable underneath the cover layer is provided. The flexible material facilitates the expulsion of air from the interior of the receptacle.

Problems solved by technology

In accordance with one embodiment, a one-way valve is disclosed which allows for air expulsion from a receptacle but does not allow water or moisture into the interior of a receptacle.

The flow of unwanted components through the perforated baffle layer creates pressure that results in the separation of the resealable section of the baffle layer from the remainder of the baffle layer and the unhinging of the resealable section of the baffle layer from the base layer.
