-1- Abstract: A container end for use in a container for pressurized liquid includes a push-in easy opening pouring closure defined by a weakening line. There is also a smaller pressure releasing closure defined by a weakening line and capable of being opened by a push-in force. The pressure releasing closure is formed partly within the pouring closure and partly outside the pouring closure. The pressure releasing closure is so arranged as to be permanently opened when the pouring closure is opened to create an air venting passageway. Both the closures are integrally connected to the container end at a position adjacent the periphery of the end whereby the permanently opened pressure releasing closure creates a liquid draining opening that facilitates substantially complete draining of the contents of the container.
