The present invention relates to a bi-layer pre-oil valve assembly and method of making that may be attached to a receptacle that provides a fluid resistant seal but allows for the expulsion of air pressure from the interior of a receptacle. The valve assembly may include a base layer, an adhesive layer, a fluid layer, and a material layer. The fluid layer may be a low viscosity fluid that is applied during the manufacturing of the valve and incorporated into the layer of the valve. The base layer may include an aperture. The adhesive layer may be provided about a portion of the perimeter of the base layer to define a non-adhesive portion. The fluid layer is applied along a portion of the non-adhesive portion of the base layer to define a channel or path to facilitate the release of gas or fluid from the receptacle. |
