Q:

When were pop top cans invented?

A:

In 1959, Ermal Fraze invented the pull tab can, which was a major improvement that allowed drinkers easy and quick access to drinks. The Pittsburgh Brewing Company in Pittsburgh Pennsylvania was the first company to use Ermal Fraze's improved design.

The improved can design by Ermal Fraze made it so that users only had to pull a removable tab to open their drink. Many users of the pull top can threw the tab on the ground, which increased litter in the United States, while others injured themselves by accidentally swallowing the tab or getting cut by it. The issue was remedied in 1977 when Fraze developed the first push-in fold-back tab. This ensured that the tab would remain attached to the can and prevent further injuries and littering.
