Abstract
A gasket that is capable of venting gas from a positive pressure gas generating system in a package, such as a bottle or a container. In so doing, the gasket prevents the liquid contained within the package from leaking out. The gasket has a core that is impermeable to liquids, with a first side and a second side opposite the first side. A first outer layer is connected to the first side and a second outer layer is connected to the second side. The first outer layer and the second outer layer are made of a gas permeable membrane. Furthermore, the gasket provides a method of venting gas from the package. The method includes securing a closure fitting shaped to form a seal to an opening of a package. The seal contains a gasket capable of venting gases while preventing liquid from leaking therefrom.
