The closure consists of a filling nozzle (10) and a screw cap (20). The filling nozzle (10) consists of a piece of tube (11) with a flange (12). Formed at the upper end of the filling nozzle is an external thread (13). A valve cone (16) is held via webs (15) centrally in the filling nozzle (10). The screw cap (20) has an internal thread (22) which fits onto the external thread (13) of the filling nozzle (10). A cylindrical, central discharge tube (24) passes through the cap surface (23). When the screw cap (20) is screwed on, the lower end (25) of the discharge tube (24) is pressed onto the valve cone (16) of the filling nozzle (10). To seal the two parts relative to each other, the upper end of the filling nozzle (10) is provided with a concentric wall (17) against which an annular wall (26) of the screw cap (20) bears in a sealing manner. <IMAGE>
