Abstract
A bottle cap comprises an outer casing of metal, pref. aluminium, coated internally with a firmly bonding layer of plastics, this coating being welded at least locally to the internal stopper which fits into the bottle neck, in the weld region, the material of the stopper is compatable with the coating so that it can be welded to it, resulting in one undetachable unit for the entire cap, Preferred materials for the internal coating and also stopper are polypropylene and hexymetafluorethylene.
