ABSTRACT:
A lid for sealing a container has a removable tear skirt. The lid includes a cap portion with a circular crown and depending sidewall. An undulating annular groove which defines a frangible thin walled strip divides the sidewall into an upper section and a lower tear skirt. The cap portion has a reinforced inner wall assembly that is spaced apart from an outer depending wall, the tear skirt being attached to a lower portion of the outer wall. A weakened area adjacent to and intersecting a small lateral slot formed in the undulating groove facilitates breaking of the tear skirt. When the tear skirt is removed, a plurality of bendable flaps are formed at the lower portion of the outer wall. A fastening rib formed on an inner surface of the outer wall is configured to lockingly engage a locking flange on the container for securing the lid to the container. Opening slots provided in the flaps are configured to receive a tool for disengaging the fastening ribs and the locking flange.
