Abstract
A lid for containers, such as cans which have an edge (B) connected to a side flank (2A) of the container (2). The has a groove (10) having a “U” section following around the side flank (2A) of the container (2). A pre-fracture line (3) is made in a bottom (10A) of the groove (10). A weakening line is provided in an edge joining an inner wall (10B) of the groove (10).
