<p>A tamper-evident top closure lid construction for a container. The lid is integrally formed from a plastic cover member, the member carrying a main and a secondary paperboard insert on its upper surface, the member and insert being bonded together. The plastic cover member has an integral tongue to define, upon tongue pivoting, an opening in the member. The main paperboard insert is hingéd about a contiguous pivot axis. the secondary insert carries a pull tab. If formed from a brittle plastics material, pulling the pull tab breaks the plastics member at its tongue hinge. The pull tab is so formed as to indicate tampering to a prospective purchaser of the container provided with the top closure lid construction of this invention. The lid may also be provided with an upstanding rim to facilitate stacking.</p> |
