Modern drink cans feature non-removable stay-on pull tabs

Lever tab rivets push pre-scored metal flaps inward without creating loose litter

Early aluminium beverage cans used detachable ring tabs that created sharp metal litter. Engineer Daniel F. Cudzik invented the non-removable stay-on tab for Reynolds Metals in 1975. The tab acts as a class-one lever, using a tiny central rivet as a fulcrum to push a pre-scored oval panel inward into the can.
