I designed this after hearing about people almost dying from a wasp sting that got in their mouth when drinking from a can of soda. the solution is a lid that clicks on a soda can with a rotating top lid so you can open it when you want to drink, and close it when you are not, keeping wasps and the like out of it.

I added serated edge for better grip when opening with index finger.
