CORROSION RESISTANT CLOSURE CONSTRUCTION

摘要

A closure panel (48) for a composite closure which is formed of a corrosive metal and while the metal of the closure panel (48) is coated on both edges, in the formation thereof a raw edge (42) develops. In lieu of a straight peripheral flange (34) terminating in such raw edge (42), the peripheral flange (34) has been modified to terminate in a curl (50) with the raw edge (42) being protected by the curl (50).
