Embodiment Construction

[0024]The present invention is now illustrated in greater detail by way of the following detailed description which represents the best presently known mode of carrying out the invention. However, it should be understood that this description is not to be used to limit the present invention, but rather, is provided for the purpose of illustrating the general features of the invention.

[0025]Referring now to the Figures and initially to FIG. 1, a multi-layer control device 10 that provides an effective seal while still enabling the expulsion of unwanted components 60 from a receptacle to which the device 10 is attached, is disclosed. The multi-layer control device 10 includes a patterned under layer of adhesive 20 forming an opening 21. The adhesive has a top face 63 and a bottom face 62. A permeable layer 11 may be included and has a top face 13 and a bottom face 12 provided over the top face 63 of the adhesive layer 20. The permeable layer 11 covers the opening and the patterned und...

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 ...
