The mechanism used for opening cans has replaced the pull-back tab mechanism with a sliding key mechanism which the key can also be used after opening as a fork, useful for ‘on the go’ consumption. The key- is made from injection moulded poly propylene because it is food safe, relatively low cost, recyclable and quite strong. The key is positioned onto the lid after the can is sealed and heated. The rivet- in which the key locks into is rivetted onto the lid part before the outer edge of the lid is rolled onto the can.
