A lid for use in an easy open can including a lid panel provided with a weakened portion defining a tear line, a tab fixed to the lid panel near the tear line having an end portion adapted to cut into the lid panel and a concave rib formed in the lid panel adjacent to the tab to permit deformation of the lid panel when the tab is lifted during the opening of the can to prevent the tab from breaking off the lid panel. |
