A Brief History of Flat Top Beer Cans

Problems with the Pull Tab

The pull tab was not without problems. Iron City printed no instructions on top of their can, creating confusion for some drinkers. When pulled, the tab sometimes left sharp edges that could cut lips and tongues. Worse, sometimes the tab would break off before removing the entire metal strip, creating thirsty and angry non-drunks. There was also the new problem of litter; thin pieces of metal appeared in the wake of any drinking session. It was clear that the technology was far from perfect.
