ABSTRACT:
A container lid is formed from a disc having thin walls of uniform thickness throughout which span and overlap the open end of the container. The overlapping portion includes a downwardly depending resilient skirt that partly overlies in engaging relation one surface of the sidewall adjacent the open end. Complementary engagement means are formed in the skirt for releasably engaging lid engagement means such as a continuous bead or groove that comprise an integral part of the container. A reclosable tear strip defines an opening through which the contents of the container may be discharged and forms an integral part of the disc and the skirt. The strip has sides defined by fracture lines formed in the disc, an outer end defined by the lines extending into the skirt to include the complementary engagement means and an inner end forming a hinge along a weakened line in the disc. In one embodiment the tear strip extends to the bottom edge of the skirt while in another, the strip ends before the edge to form a continuous reinforcement band around the container.
