The closure has a bung-type socket (10) of elastic material which fits sealingly into the filling hole and is provided with a central orifice (18). The valve element (20) of the pressure-compensating valve occupies in the central orifice a clearly defined closed position and a clearly defined pressure-compensating position, between which it can be turned within limits defined by stops. The bung-type socket (10) has a lateral pressure-compensating duct (42), the outside end of which is disposed above the liquid level in the completely filled container. The valve element (20) in pressure-compensating position opens up a flow path from the inside end of the pressure-compensating duct (42) to the upper side of the bung-type socket (10), while in closed position it shuts off the path on the inside, covers it on the outside and seals it tightly on both inside and outside.

[ What is claimed is:] [1.] A closure with pressure-compensating valve for the filling hole of a liquid container, with a bung-type socket of elastic material which fits sealingly into the filling hole and is provided with a central orifice, and with a valve element which can be manually turned into position and which occupies in the central orifice a sealing closed position and a pressure-compensating position, in which the interior of the container is in communication with the atmosphere, characterized in that the bung-type socket (10) has a lateral pressure-compensating duct (42), the outside end of which is disposed above the liquid level in the completely filled container, in that the valve element (20) can be turned within limits defined by stops from a clearly defined closed position to a clearly defined pressure-compensating position and back, and in that the valve element (20) in pressure-compensating position opens up a flow path from the inside end of the pressure-compensating duct (42) to the upper side of the bung-type socket (10), while in closed position it shuts off the path on the inside, covers it on the outside and seals it tightly on both inside and outside.
