- A closure with pressure-compensating valve for the filling hole of a liquid container, with a bung-type socket (10) which fits sealingly into the filling hole and is provided with a central orifice (18) and a lateral pressure-compensating duct (42), the outside end of which is disposed above the liquid level in the completely filled container, and with a valve element (20) which can be manually turned into position in the central orifice (18) within limits defined by stops from a clearly defined closed position to a clearly defined pressure-compensating position, whereby 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 seals the path tightly on both inside and outside, characterized in that the bung-type socket (10) consists of elastic material, in that the valve element (20) has an external flange (44), which fits into a recess (32) of the bung-type socket (10), in that on the bottom of the recess (32) there is provided a groove (66) extending outward from the central orifice (18), which is covered by the flange (44) in the closed position, and in that the valve element (20) has a surface groove (65), which in pressure-compensating position brings the inside end of the pressure-compensating duct (42) into communication with the groove (66) on the bottom of the recess (32).
- A closure according to claim 1, characterized in that the flange (44) is noncircular and in closed position and pressure compensating position it snaps radially onto the outside of the bung-type socket (10) with a projection (68), and in that in closed position the projection (68) covers the outside end of the groove (66) on the bottom of the recess (32).
- A closure according to claims 1 or 2, characterized in that the valve element (20) has a notch (62) extending over its circumference, and in that the bung-type socket (10) is provided with a cog (64), which locates the notch (62) and becomes stopped at the ends thereof, thereby limiting the adjustment angle of the valve element (20) and defining the closed position and pressure-compensating position.
- A closure according to one of claims 1 to 3, characterized in that the portion of the valve element (20) disposed opposite the inside end of the pressure-compensating duct (42) forms in circumferential direction a ramp, which descends in turning direction from closed position to pressure-compensating position.
- A closure according to one of claims 1 to 4, characterized in that it has an originality-protecting feature, which reveals whether or not the pressure-compensating valve has already been actuated.
- A closure according to one of claims 1 to 5, characterized in that the valve element (20) is provided with a liftable curved handle (74), which is fastened to the valve element (20) by means of ribs (78), which break away when the handle (74) is lifted for the first time.
- A closure according to one of claims 1 to 6, characterized in that the curved handle (74) attached to the ribs (78) is flush-mounted in the recess (32) of the bung-tpye socket (10).
- A closure according to claim 7, characterized in that the recess (32) of the plug-tpye socket (10) has a widened portion (80), which allows the curved handle (74) to be grasped from underneath.
- A closure according to one of claims 1 to 8, characterized in that the bung-tpye socket (10) is made in the two-plastic technique from a soft external part and a hard reinforcing ring completely embedded therein.
