Container and closure therefor.

摘要

A closure for a container having a neck portion (38), a plug (28) which has a fluid-tight fit within the neck portion, and a manually openable pressure release valve (89) associated with said plug operative upon being opened to release the pressure in the container and also to condition the plug for relatively easy withdrawal to open position. The closure also provides a novel assembly of parts which are easy to open and close and which in open position holds the parts in position to not obstruct pouring or drinking directly from the container or bottle and the closure provides a novel plug insertion structure which facilitates closure.
