ABSTRACT:
A bung hole closure for cans is described, in which a liquid is stored under pressure or without pressure and from which it is removed under pressure by means of a tap fitting. It comprises a plug-like soft portion bored thru axially having at least one sealing portion in the inside bore, a projection serving for support on the rim region of the can lid surrounding the can opening and a seal seat for the rim of the can opening provided underneath the projection. This soft portion is surrounded by a reinforcing hard portion in the form of a sleeve, which has a projection which is embedded in the projection of the soft portion. The jacket of the sleeve is perforated and has smooth continuous webs and, arranged between these webs, conically outward protruding catches which can be pushed into the material of the soft portion.
