Abstract
A plastic container lid is disclosed for a container having double locking flanges around its upper peripheral edge for locking engagement with the lid. The lid has a central portion in a peripheral annular skirt. The skirt has an annular groove dividing the skirt into an upper portion and a lower tear-off strip portion. The upper portion has intermittent locking flange segments for engaging one of the container locking flanges. The tear-off strip portion has a second locking flange for engaging the other of the container locking flanges. Thin membrane windows are formed in the skirt upper portion on either side of the intermittent locking flange segments and bordering on the annular groove, so that the membrane windows form weakened notches upon removal of the tear-off strip portion to facilitate upward deflection of the lid annular skirt in the area of the intermittent flange segments to facilitate removal of the lid.
