Patent ID: 8616405

Claim:
A drink cup lid comprising a ring-shaped brim mount adapted to mate with the brim of a cup associated with the drink cup lid and a central closure surrounded by the ring-shaped brim mount, wherein the central closure includes an elevated basin arranged to extend upwardly above the ring-shaped brim mount and away from any cup mated to the ring-shaped brim mount and formed to include a spout with a liquid-discharge outlet, the central closure further includes a radially outwardly extending flange arranged to surround the elevated basin and interconnect an outer perimeter edge of the elevated basin and an inner perimeter edge of the ring-shaped brim mount to define a ring-shaped low-elevation liquid-retention channel above the radially outwardly extending flange and between the elevated basin and the surrounding ring-shaped brim mount, and the elevated basin is formed to include a raised liquid-collection region below the liquid-discharge outlet and above the ring-shaped low-elevation liquid-retention channel and to include a first side-discharge channel located between a raised upstanding ridge and the spout and interconnecting the raised liquid-collection region and the ring-shaped low-elevation liquid-retention channel to provide first channel means for conducting any overflow liquid leaking inadvertently out of a cup coupled to the drink cup lid through the liquid-discharge outlet into the raised-liquid collection region formed in the elevated basin downwardly along a first predetermined path on an exterior surface of the elevated basin into the ring-shaped low-elevation liquid-retention channel.
