It seems whenever I am out in the backyard I’ll find a pop-top. This can-opening method dominated the canned beverage market when in 1959 Ermal Fraze devised the “pull-tab” or pop-top, as it made a popping sound when you opened the can. This eliminated the need for a separate opener tool. It became widely popular in the 1970’s but it came with a significant problem as people would frequently discard the pull-tabs on the ground as liter (in my yard!) or drop them into the can and risk choking on them. The safety and litter problems were both eventually solved later in the 1970’s with Daniel F. Cudzik’s invention of the “Stay-Tab” that we use today. Must have been lots of parties at the house during the 1970’s!
