Tab from ring pull canThe ring pull can was invented by Ermal Cleon “Ernie” Fraze of Dayton, Ohio, in 1959.  It was first put to the test by Iron City Brewing in Pittsburg in 1962 and soon became widely used for beer and soft drinks. The original ring pull detached from the can and caused litter. To solve this problem, Fraze invented the first push-in, fold-back tab which was patented in 1977.
