Abstract

Abstract A drinking container includes a cup including a bottom, a side wall surrounding an interior of the cup and having an upper peripheral edge, and a U-shaped, elongate trough integrally formed with the side wall and extending upwardly therefrom, beyond the upper peripheral edge. A lid includes a generally circular base with a downwardly extending peripheral flanged lip structured for releasable attachment over the upper peripheral edge of the side wall of the cup and a trough cover integrally formed with the base and extending upwardly therefrom. The trough cover includes an outer, generally convex surface, an inner generally concave surface, and opposite sides having a flanged lip structured for releasable attachment over the side edges of the trough so that when the lid is attached to the cup, the combined trough and trough cover form a drinking spout extending from the cup and terminating at a spout opening.
