Type 4 – United Kingdom Snap Cap
1947 – 1960s
The Type 4 can is all metal and has a cap that snaps on and off the can. It was made in England from around 1947 until the early 1960s. There is also an inner disc that must be pressed to release the factory pressure packed air. Once a Type 4 can is opened, the inner disc is usually discarded, therefore, it is not commonly seen with cans. This type of can is also known as a ‘disc lid’.
