Abstract
A container lid, adapted for use with a cold or hot drink, is provided with a condiment reservoir built into the lid. An orifice for drinking a liquid in the container is provided on one side of a planar surface forming the lid and an open top recess, forming the condiment reservoir, is provided on the other side. Closed side walls and a bottom extending down toward the container serve to form the reservoir. The condiment can be carried directly in the reservoir or in a condiment holder, such as a packet or cup, placed in the reservoir. The side walls extend at an acute angle from the planar surface to allow multiple lids to nest together prior to use. A mating groove and annular projection in the recess and on a cup, respectively, serves as a snap fit interlock system to hold the cup in place. The side walls of the recess include a semicircular wall and a diagonal wall connecting the ends to form the reservoir. Alternatively, the recess can be various shapes, including cylindrical, rectangular or multiple recesses connected together, as well as various sizes. If desired, the recess can be deep enough so that the reservoir is positioned in ice when a cold drink fills the container.
