Abstract
A non-spill drink-through lid is provided with a retainer support wall defined in a chord position across the central cover portion thereof. The retainer support wall merges with the raised outer peripheral edge of the lid to define a well portion which encompasses a depressible tab portion defined by a slit provided in the central cover portion. The well portion is adapted to retain excess liquid above the slit so as to permit the excess liquid to drain back into the interior of the cup upon which the lid is mounted. Another embodiment of the invention consists of the non-spill drink-through lid having a pair of identical parallel spaced-apart cup support walls defined in the central cover portion of the lid and extending thereacross to merge at the ends thereof with the raised outer peripheral edge of the lid. Thus positioned, the cup support walls are adapted to stackably support another cup positioned thereon.
