Four distinct designs were used in the design and development of opening mechanisms for aluminum cans. To get the liquid out of the can, one large hole or two smaller holes are needed. If two holes are needed, the first hole is designed to let air into the can, and the second hole is designed to ...

Another simple machine was built into the removable tab top. It consisted of a small ring that acted like a lever and would make the necessary hole by removing the tab from the can. This was a huge
improvement, but it also created a huge problem. The problem it created was ...
