Patent ID: 8631957

Claim:
A thermoformed disposable, recloseable lid for closing an open top of a cup terminating in an annular upper edge, the lid comprising: a cup mount defining an annular channel for receiving an annular upper edge of a cup for mounting the lid to the cup; a cap comprising: an upper surface located above the cup mount; a peripheral wall with a positive draft angle extending upwardly from the cup mount and terminating at the upper surface; and a mounting recess formed in the upper surface and at least partially defined by a peripheral wall extending downwardly from the upper surface at a negative draft angle to form an undercut relative to the upper surface and an opening for the mounting recess; a thin-walled hollow structure extending above the upper surface and terminating in a top wall located above the upper surface and a drink opening located in the top wall; and a tab closure comprising a mounting plug and a drink plug connected by a strap, the mounting plug is at least partially defined by a peripheral wall having a negative draft angle such that when the mounting plug is received within the mounting recess to mount the tab closure to the cap, the peripheral wall of the mounting plug lies within the undercut, and the drink plug is received within the drink opening to close the drink opening, and the strap is configured to permit the insertion of the drink plug into the drink opening when the mounting plug is received within the mounting recess, whereby a user can open and close the lid by removing or inserting the drink plug from the drink opening while the tab closure remains mounted to the cap; wherein the cap, cup mount, and tab closure all have a common thickness and are fabricated of a flexible, thin-walled plastic by a conventional thermoforming process.
