Abstract
The top (2) of a sheet metal container (1) for the transportation and storage of liquids has a central fill opening (3) which is edged by a neck (5) which is perpendicular to the top surface (4) of the container. A plastic or metal ring (6) with an external thread (7) is pressed down against the top surface (4) by the upper edge (8) of the neck (5). The neck is swaged outwardly. The threaded ring (6) is protected against rotation by form-fit connections on the neck (5). A plastic screw cap (11) into which a disc-shaped insert (12) of special steel is pressed, is screwed onto the threaded ring (6). Between the outside edge (13) of the cap insert (12) and a ring projection (14) of the latter, an annular groove (15) for holding a gasket (16) is molded into the insert, and by this gasket (16) the screw cap (11) is sealed against the upper edge (8) of the neck (5).
