ABSTRACT OF THE DISCLOSURE A metal closure cap is described for sealing containers. It is of the lug type having a metal shell with a flowed-in gasket. The cap differs from prior twist caps of this general type by having a tapered corner between the cap top and the cap skirt. This corner design permits a reduced amount of metal to be used and further provides a more rigid closure corner permitting the use of lighter-weight metal. Improved methods of forming the cap shell, including the corner portion are also described.
