PCT No. PCT/SE92/00168 Sec. 371 Date Sep. 17, 1993 Sec. 102(e) Date Sep. 17, 1993 PCT Filed Mar. 18, 1992 PCT Pub. No. WO92/16449 PCT Pub. Date Oct. 1, 1992.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. The device includes a generally cylindrical housing which is releasably mountable at its open end over the hole. 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.
