caption_attribution_description: English: Photograph taken 6 March 2009 showing a w:pull tab in use on a can of Tsingtao Beer (青岛啤酒) in Beijing, China. I kid you not, a pull tab. Haven't seen one of those for years. Presume it is a patent use fee savings. Yes, the photo date stamp shows the date as 5 March on the photograph - but, having crossed the International Date Line but not having reset the camera clock, the camera was wrong. It was actually taken on the 6th. Skål - Williamborg (talk) 01:13, 8 March 2009 (UTC)
context_page_description: A drink can is a metal container designed to hold a fixed portion of liquid such as carbonated soft drinks, alcoholic drinks, fruit juices, teas, herbal teas, energy drinks, etc. Drink cans are made of aluminium or tin-plated steel. Worldwide production for all drink cans is approximately 370 billion cans per year worldwide.
context_section_description: Mikolaj Kondakow and James Wong of Thunder Bay, Ontario, Canada invented the pull tab version for bottles in or before 1951 (Canadian patent 476789). 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.
  The early pull-tabs detached easily. In 1976, the Journal of the American Medical Association noted cases of children ingesting pull-tabs that had broken off and dropped into the can.
  Full-top pull-tabs were also used in some oil cans and are currently used in some soup, pet food, tennis ball, nuts, and other cans.
