ABSTRACT:
Method for shaping a sheet metal lid, preferably for a beverage can, which includes a panel, an openable area defined in the panel by a score line, and a mounting place for a tab for breaking into the openable area. At least one projection in the panel is shaped twice, such that a pre-form of the projection is shaped out of the panel of the sheet metal lid, in which the pre-form is located near an attaching portion of the tab, but at a distance from a the mounting place, and at least a front edge of the pre-form of at least one projection is re-formed, so that no score line is provided in the panel during shaping or re-forming. Further, to obtain better blocking of an outer edge portion of the attaching portion, an outer edge portion is associated with the re-formed front edge. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
