Pull-off bottle cap

RingCrown (also known as RipCap, Ring-pull closure or pull off caps) is a bottle closure that can be opened without any tools. It has a ring that can be pulled and therefore detach the cap from a bottle. The cap splits along scores in the cap so it loosens from the bottle and is removed. Drink companies use ring pull caps to differentiate from competitors.[1]

History

"ALKA", the predecessor of modern ring-pull caps were introduced during the 1930s. ALKA had a seal made of natural cork. It became popular in Nordic countries as an easy-to-open cap. Alka made of aluminum had a tab that is pulled to remove the cap. There is no scoring on an ALKA cap. In the 1970s the MaxiCap was first produced. A MaxiCap is an aluminum closure with scoring and a tab to pull. They were easier to use than the ALKA and pre-manufactured outside of the bottling plant. This allowed for increased production speeds on the bottling line. Soon after the MaxiCap, came the RingCrown closure. Invented in the early 1980s originally called MaxiCrown and later known as RingCrown. RingCrown is easier to use than its predecessors, it has an attached ring rather than static pull off tab.[2]
