Around aluminum — or aluminium in Europe — was introduced as a material for the can end, which made it much easier to punch open. This device was used to make two triangular holes in the can end to access its content. However, soft tops did not make it long in the world of packaging…. In Fraze patented a new design which would further revolutionize the market and would soon make the punch top and church key obsolete see also the work of archaeologist W.
Schroeder at Montana University Responding to complaints about low grip and sharp edges of zip-top tabs, which apparently cut fingers and lips, American Can Company ACCO started production of one of the first designs in using a pull ring , in stead of a solid flat zip-top tab. In effect the rings on these tabs proved too small to actually put a finger through for pulling, so the design was replaced by bigger rings that same year by ACCO and by Continental Can in Both companies introduced designs that in essence would stay in production for at least a decade in the USA and longer in other countries.
Cans sold in the Dutch market at the end of the s still held a tab very similar to the one produced by Continental in Responding to consumer and governmental complains that the ring pull tabs could still cut hands, lips and feet when stepped upon on recreational beaches, were sometimes swallowed when put in the can, and were littering the environment, can companies switched to a new style of tab in the 70s.
European countries made a similar switch some 10 to 15 years later. As our Pull Tab Archaeology project will show, developments did not stall after In continued efforts to ease opening, reduce costs and gain more profit, tab designers have come up with numerous small variations and improvements up to today. The number of different types of pull tabs that exist in the world is unknown and just one of many questions addressed in our project.

This system had two openings — a small pressure-release valve and a larger opening for drinking from. The circular tab remained attached after it was pushed in. It had its own problems though: you were likely to cut your finger pushing in the tab.
The problem was finally solved by US engineer Daniel F. Cudzik, who developed what he called the Sta-Tab, the fold-back opening common on soft drink cans today. The new device was patented in and has been universally adopted as the standard opening system for beer and soft drink cans.
