ABSTRACT:
A bung screw-threadedly received in a receptacle has a plurality of flow openings therethrough disposed in a series about the axis of the bung, and an axially movable valve disc for simultaneously opening or closing all of the openings. Each opening has a thin penetrable closure which can be penetrated without disturbing any of the other closures. In this way, when the container is tilted to discharge the contents, only the closure of the flow opening which is lowermost need be broken. The disc can then be manipulated to open and close the bung, without the contents of the container flowing over the tools and the hands of the operator who opens and closes the disc.
