The Evolution of the Pull Tab - Because We Don’t Always Find ‘Treasure’
History, Waste of Time 1 Comment »If you consider yourself a metal detectorist of any caliber then you have an extensive collection of pull tabs. If you’re anything like me, you wonder where the heck they all came from. So I did some digging around online to see what I could find about them and got a pretty good history lesson.
In the early 1960’s the Pittsburgh Brewing Company introduced “Iron City Beer” in ‘self-opening cans.’ The concept was pretty novel – just pull up on a tab and you had an open can of beer in your hand! No accessories like a ‘church key’ or bottle opener neccessary - imagine that! These early pull tabs were known as “zip tops” and were disposable. But because of the rough edges of the aluminum, the cans often left people with cuts on their fingers, lips and even noses. ![]()
But the revolution had begun! By 1965 the design was changed to the ring style, which I’m sure every metal detectorists has seen his or her share of. The ring style was even easier then the zip top; just put your finger into the ring, yank forward and have your beverage with less potential for physical injury - even better!
Needless to say, the swift evolution of the zip top to the ring tab revolutionized canned beverages. By the mid-60’s over 75% of all cans produced in the U.S. had a pull-tab opening.
But for all their convenience, the pull tabs were an environmental and metal detectorist’s nightmare. For 10 years people opened cans, ripped off the pull-tabs and threw them to the side because they were encouraged to - there was nothing else to do with these removable metal pieces. Pets and wildlife died from ingesting them, as did a few people who dropped them into a can and accidentally choked on them. They wound up everywhere – from beaches and parks, to playgrounds and garbage disposals. People routinely cut themselves in a time when hand sanitizer wasn’t in every woman’s purse.
Ten years after the “ring” version of the pull tab was introduced, an answer to this environmental and safety nightmare finally came. The “stay tab” style was introduced in 1975 by the Falls City Brewing Company, and they were here to stay – literally. These ring-style-stay-tabs are what we can see on every can of coke and beer in the grocery store today. Unfortunately, they don’t stay quite as well as the designers would have liked. But at least this style doesn’t force people to throw the tab aside… they actually have to do a little work to get it off.
Thankfully, metal detectorists like you and me pick these up as we go… cleaning the beaches, parks and playground for the future, all in the name of a healthy hobby. Personally, I think we live in a disposable world now-a-days, and I wonder when we’ll figure out that convenience comes at the price of our environment. But that’s another conversation, meant for another day. In the meantime, keep picking those pull tab’s up, and thank Pittsburgh Brewing Company for the introduction of your most frequent find.
