Zusammenfassung:	A closure is provided for a container opening. The opening is defined by a neck extending outwardly from the top of the container. The closure includes a liner cap disposed both interiorly and exteriorly of the neck and defines a central passage. A plug extends across the top of the cap to close off the passage from the exterior. The plug is provided with at least one longitudinal hole. The lower end of the plug has attached thereto a membrane extending across the passage. This membrane does not permit liquids within the container to pass therethrough, but possesses the property of being capable of venting gasses therethrough. A dust cap may extend across the top of the closure during shipment and storage.
