ABSTRACT:
A filling and discharge bunghole bunghole (9) and an aerating and venting bunghole (10) are arranged in protected fashion in depressions (11, 12) of the lid portion (4) of the bunghole barrel. The stacking surface (8) of the lid portion (4) passes over into two webs (17, 18) extending in the circumferential direction and encompassing the bottom surface of the depression (11) for the filling and discharge bunghole (9), these webs running with a slight slope from the stacking surface (8) toward the bottom surface of the depression (11) and forming, in the slightly tilted upended position (1') of the bunghole barrel, drainage channels (21, 22) for the residual fluid (24) collecting on the inside (27) of the lid portion (4) and flowing off through the bunghole opening (15) of the filling and discharge bunghole (9).
