[Category : - OTHER]
[Viewed 346 times]

A one-way valve to control the release of pressurized gas from within a sealed container through a venting aperture. The valve comprises a layer of flexible material having an upper and a lower surface with a portion of the upper surface adhered to a surface of the container and overlaying the venting aperture. A channel is defined by a portion of the container and an adjacent portion of the flexible material which has not been adhered to the container. The channel is in communication with the venting aperture and an exhaust gas aperture in the layer of flexible material. The channel is operable between a closed and an open configuration upon gas pressure within the container exceeding a predetermined limit. When open the channel permits gas to flow from said container into the exterior atmosphere. When closed the channel restricts the flow of gas between the venting aperture and exhaust gas aperture.
