  • Increased strength for metal beverage closure through reforming
    Patent number: 4641761
    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.
    Type: Grant
    Filed: September 5, 1985
    Date of Patent: February 10, 1987
    Assignee: Ball Corporation
