Abstract: A metal container or component part of a metal container (e.g. a can end or sidewall of a can body) has an aperture defined by a cut edge about the periphery of the aperture, with a cover element sealed to the outward-facing surface of the can end so as to extend over and cover the aperture. A film of lacquer is directly applied (without the presence of an intermediate primer layer) to the inward-facing of the container/component part so as to coat the entirety of the cut edge and all or part of the inward-facing surfaces of both the can end and that part of the cover element located radially inward of the cut edge, thereby inhibiting corrosion of the cut edge. The invention is particularly suitable for can ends. The invention also relates to a method of making a can end to the invention.
