A plastic container lid (10) is disclosed for a container (12) having double locking flanges (18, 20) around its upper peripheral edge for locking engagement with the lid. The lid has a central portion (14) and a peripheral annular skirt (16). The skirt has an annular groove (30) dividing the skirt into an upper portion (32) and a lower tear-off strip portion (34). The upper portion has intermittent locking flange segments (36) for engaging one of the container locking flanges. The tear-off strip portion has a second locking flange (38) for engaging the other of the container locking flanges. Openings (40) are formed in the skirt upper portion on either side of the intermittent locking flange segments (36) and borderin g on the annular groove (30), so that the openings form weakening notches upon removal of the tear-off strip portion (34) to facilitate upward deflection of the lid annular skirt (16) in the area of the intermittent flange segments (36) to facilitate removal of the lid.
