<P> In 1959 , the recyclable aluminum can was introduced to the market in a 7 oz . size by the Adolph Coors Company . Also in 1959 , Ermal Fraze devised a can - opening method that would come to dominate the canned drink market . His invention was the `` pull - tab '' . This eliminated the need for a separate opener tool by attaching an aluminium pull - ring lever with a rivet to a pre-scored wedge - shaped tab section of the can top . The ring was riveted to the center of the top , which created an elongated opening large enough that one hole simultaneously served to let the drink flow out while air flowed in . In 1959 , while on a family picnic , Mr. Fraze had forgotten to bring a can opener and was forced to use a car bumper to open a can of beer . Thinking there must be an easier way , he later stayed up all night until he came up with the pull tab . Pull - tab cans , or the discarded tabs from them , were also called `` pop - tops '' colloquially . In Australia these were colloquially known as `` ring - pull '' . Into the 1970s , the pull - tab was widely popular , but its popularity came with a significant problem , as people would frequently discard the pull - tabs on the ground as litter , or drop them into the can and risk choking on them . These problems were both addressed by the invention of the `` push - tab '' . Used primarily on Coors Beer cans in the mid-1970s , the push - tab was a raised circular scored area used in place of the pull - tab . It needed no ring to pull up . Instead , the raised aluminium blister was pushed down into the can , with a small unscored piece that kept the tab connected after being pushed inside . Push - tabs never gained wide popularity because while they had solved the litter problem of the pull - tab , they created a safety hazard where the person 's finger upon pushing the tab into the can was immediately exposed to the sharp edges of the opening . An unusual feature of the push - tab Coors Beer cans was that they had a second , smaller , push - tab at the top as an airflow vent -- a convenience that was lost with the switch from can opener to pull - tab . The `` push - tab '' was introduced into Australia in the early 1980s and was locally known as `` pop - tops '' . </P>
