Abstract
Methods and apparatus for forming a convenience-feature, sheet metal end closure structure (133) for a container body (153) having a non-cylindrical side wall. A new scoring tool (94) configuration enables a peripheral scoreline (102) defining a separable convenience-feature panel (112) to be located contiguous to the closure chuck wall (100) which interfits about its entire periphery with the open end of the side wall of such a container. Separation of such panel leaves substantially no obstruction to removal of solid-pack container. The separable panel (112) is formed with a multiple-layer fold (127) of sheet metal which is nested against the interior periphery of such panel, so as to shield torn residual metal remaining with the panel after severance along such peripheral scoreline. And, preselected placement of an elongated integral openers (148) as designated on various non-circular configuration endwall panels, along with novel shaping of chuck wall tooling (170), enables desired chuck wall support for chime seam assembly of such sheet metal end closure to a container body.
