Abstract
This application is concerned with a can end comprising an end plate and a tab, the tab and end plate being so adapted to one another that by bending of the tab up by one desiring to open the can, the tab forces a section of the can to pivot inward, thus allowing access to the contents of the can without detaching any piece of the end or tab. The can end is made of aluminum, and the tab is made of steel coated with a material so chosen as to minimize or eliminate corrosion of the steel. In a preferred embodiment, the steel tab is coated with zinc.
