  • Patent number: 4420111
    Abstract: A drinking cup and cover combination is provided. The cup has a substantially rectangular mouth, walls and an open top extending to the walls. The cover for the cup includes a plurality of downwardly depending lips, which in cooperation with an arcuate lip on the cup allows the cover to be releasably retained on the mouth of the cup and permits sliding movement of the cover parallel to two parallel sides of the cup mouth and between first and second extreme positions. The foregoing structure permits the cover to completely close the mouth of the cup when it is in the first position and to form a pouring aperture at the mouth of the cup when the cover is in the second position.
