Mikolaj Kondakow and James Wong of Thunder Bay, Ontario, Canada invented the pull tab version for bottles in or before 1951 (Canadian patent 476789). Then, in 1962, Ermal Cleon Fraze (1913 -- 1989) of Dayton, Ohio, United States, invented the similar integral rivet and pull - tab version (also known as ring pull in British English), which had a ring attached at the rivet for pulling, and which would come off completely to be discarded. He received US Patent No. 3,349,949 for his pull - top can design in 1963 and licensed his invention to Alcoa and Pittsburgh Brewing Company, the latter of which first introduced the design on Iron City Beer cans. The first soft drinks to be sold in all - aluminium cans were R.C. Cola and Diet - Rite Cola, both made by the Royal Crown Cola company, in 1964.
