Claim:
A spill-resistant drinking glass for holding a liquid beverage, comprising: at least one side wall having an upper edge, the upper edge forming an outer rim of a liquid reservoir; an annular contoured lip of uniform width projecting inwardly from the outer rim, said annular contoured lip forming a partial upper surface of the reservoir that reduces spillage of the liquid beverage from the reservoir when the drinking glass is moved or tilted by a user; wherein an inner edge of the annular contoured lip forms a central aperture in the upper surface of the reservoir, said central aperture being large enough to be used to fill the container and to provide access for cleaning the interior of the container; and wherein the annular contoured lip includes a second aperture located between the inner edge of the annular contoured lip and the outer rim of the reservoir for drinking from the reservoir, said second aperture being smaller than the central aperture and sized in a range of one-eighth to one-half inch to accept a drinking straw; a horizontal base for supporting the reservoir; and a vertical stem connecting the base to the reservoir.
