Plastic bottles were introduced to the bottling industry and the world in 1978. In the past 44 years, that container and closure technical changes have addressed varying attributes. However, the ability to reduce carbonated beverages’ ability to go “flat” has not been effectively addressed. That is about to change. To help consumers avoid flat soft drinks, a patent-pending gas-trap cap now is available for the carbonated beverage world.
“A check valve, inside a soda cap, what a clever, game changing design ― why didn’t anyone think of this 40 years ago?,” says the head of mechanical engineering of the Southern Alberta Institute of Technology (SAIT).
