Abstract
Metal beverage closures of increased strength may be produced by a reform process which requires the initial production of a non-standard shell having a reduced countersink radius and reduced panel height. The shell is reformed, preferably in the conversion process, to industry standard dimensions, with the reduced countersink radius being maintained. To provide adequate material in the curl portion of the closure for seaming, the initial shell is provided with a reduced chuckwall diameter which is then reformed to industry standard dimensions.
