The First Pull Tabs (1960s)
In 1962, Ermal Fraze invented the first pull-off tab. It was revolutionary—but flawed.
People loved the convenience, but injuries and litter became serious issues.
The Stay-On Tab (1970s)
In 1975, the modern stay-on tab was introduced. It solved nearly every problem of earlier designs and quickly became the industry standard.
Since then, improvements have been subtle but continuous.
The Secret Function #6: Encouraging Recycling
The tab is made from the same aluminum alloy as the can itself.
This is intentional.
Because the tab stays attached:
It doesn’t get lost during recycling
It doesn’t contaminate waste streams
The entire can can be recycled together
Aluminum is one of the most recyclable materials on Earth. It can be recycled endlessly without losing quality.
The tab plays a small but important role in making aluminum recycling efficient and economical.
The Myth: Is the Ring for Holding a Straw?
You may have heard this popular claim:
“The ring is meant to hold your straw in place.”
While clever, this is not the original purpose of the tab.
However, the design does allow for this use, and many people find it helpful for:
Keeping straws from floating up
Stabilizing straws in moving vehicles
This is an example of emergent functionality—a use that wasn’t originally intended but works because of smart design.
The Hidden Function #7: Visual and Tactile Feedback
The ring provides instant feedback that the can has been opened.
You feel it.
You hear it.
You see it.
This multisensory confirmation helps users know:
The seal is broken
The drink is safe to consume
The can hasn’t been tampered with
That feedback builds trust in packaged beverages, especially in public or shared spaces.
Why the Design Has Barely Changed
In a world of constant innovation, why hasn’t the can tab been reinvented?
Because it already meets nearly every design requirement:
Safe
Cheap
Durable
Recyclable
Easy to use
Universally understood
Engineers often refer to it as a “near-perfect design”—simple, elegant, and effective.
Any change would need to improve all of these factors without introducing new problems. That’s a very high bar.
