1529618 Pull tabs for easy-open can ends ALUMINUM CO OF AMERICA 1 Oct 1976 [22 Jan 1976] 40886/76 Heading B8D A sheet metal pull tab for attachment to the score-defined removable panel of an easy-open can end comprises a rivet-receiving attachment lug or tang 44 which is inclined out of the general plane of the tab such that, on attachment to the can end, the tang resiliently presses the tab against the can end to prevent excessive lifting of the lifting or finger-ring portion 50 of the tab from the can end when the latter is domed by internal pressure. As shown, the tab is in the form of a ring and the tang is inclined upwardly between 10 and 50 degrees to the general plane of the tab. In a modification the tang is incised from the main body of a sheet metal tab itself, Fig. 6 (not shown), between a nose portion and a finger ring portion. |
