A can lid having a top plate, a tab, a rivet, a score, a tongue, a first deboss, an emboss, a second deboss, and an embossed ridge. The first deboss is formed entirely within the score. The second deboss and emboss are formed entirely within the first deboss. The second deboss is formed by matching arcuate sidewalls, and has a sloped bottom surface. The rivet is offset from a center of the lid. The tongue is disposed between the rivet and top plate perimeter where the rivet is closest to the perimeter. The emboss is uniformly spaced from the score. An embossed ridge is uniformly spaced from the score outside of the score. In another embodiment, the second deboss is replaced with a contact emboss. A die insert for forming the first deboss, emboss, and second deboss (and, alternatively, contact emboss) is also disclosed.
