Abstract
A method and apparatus for making metallic-convenience closure for a cylindrical container by forming a panel with an endless severing line formed in the panel and defining a central removable portion and a peripheral fixed portion adapted for attaching a closure to the end of a container to close the end and attaching manually graspable pull-tab is attached to the removable portion of the panel, the pull-tab having a nose portion movable upon lifting of the tab into position adjacent the score line for severing the score line. The tab includes a first portion which is attached by a rivet to the removable portion of the panel, a second portion extending radially outwardly toward the score line, and a manual graspable portion integral with the second portion and extending radially inwardly. After the pull-tab is attached to the closure with the second portion of the pull-tab extending radially outwardly toward the score line of the panel, opposed clamping forces are applied to the exposed surface of the manual graspable portion, and the portion of the pull-tab attached to the removable portion of the panel, and a force is applied to the portion of the panel surrounded by the graspable portion of the pull-tab to deform the portion upwardly into the area surrounded by the graspable portion so that the deformed portion prevents rotation about the axis of the rivet.
