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".

The safety and litter problems were both eventually solved later in the 1970s with Daniel F.
Cudzik's invention of the non-removing "Stay-Tab". The pull-ring was replaced with a stiff
aluminium lever, and the removable tab was replaced with a pre-scored round tab that
functioned similarly to the push-tab, but the raised blister was no longer needed, as the
riveted lever would now do the job of pushing the tab open and into the interior of the can.

In 2008, an aluminium version of the container design was adopted for packaging Coca-
Cola's Caribou Coffee beverage. In 2004, Anheuser-Busch adopted an all-aluminium bottle
for use with Budweiser and Bud Light beers.
