Abstract
The present invention is directed to a top closure lid construction for a container. The lid is integrally formed from a plastic cover member, the member carrying a main paperboard insert on its upper surface, the member and insert being secured together. The plastic cover member has an integral tongue to define, upon tongue pivoting, an opening in the member. The main paperboard insert is hinged about a contiguous pivot axis, and carries a pull tab. Spaced lugs or detents are provided to facilitate reclosing of the closure. If formed from a brittle plastics material, pulling the pull tab breaks the plastics member at its tongue hinge. The closure lid further includes an upstanding wall which enables stacking.
