  • Patent number: 5413138
    Abstract: An emptying and filling device for a fluid in a container, including an emptying or filling hole closable by a bung. The bung has an outwardly open substantially cylindrical cavity and two mutually spaced projections.

After fastening the housing sealingly against a flange at the hole, a movably arranged bung holder provided with grippers is adapted peripherally to engage and retain the bung by releasable engagement with both projections of the bung, thus enabling, apart from screwing in and out the bung in the hole, a regulatable emptying or filling of the contents of the container without the container needing to be raised into a vertical position before assuming its horizontal emptying and/or filling position.
