Abstract
A cap-type container has a tube stub formed directly from sheet metal of the container cover and from which the opening can be shaped. The tube stub is externally threaded and cooperates with a cap provided with a sealing ring engaging an annular surface of the tube stub. The latter can be double walled and a reinforcing ring inserted between the walls.
