  • Patent number: 6758390
    Abstract: The cup has a lid portion extending up from one side of the cup, configured to flip down into the body of the cup, along a first score line, going from convex to concave, so as to close the otherwise open top of the cup. Flaps extend preferably from the lid portion near its lateral intersections with the cup body outwardly from the cup, or alternatively from the cup body in the same area, but inwardly. In either case, the flaps overlie what might otherwise be a small gap between the lid and the cup body in that area. This reduces any possibility for liquid to escape via that small gap. In the case of the flaps extending outwardly from the lid, the flaps also tend to act as stops against excessive downward rotation of the lid, and provide an easy way to lift the lid to open the cup, if desired.

  • Patent number: 6592504
    Abstract: The disposable cup has a bottom insert, and a substantially truncated conical body having an integral lid and a cup opening. The lid is movable between a raised position and a closed position, possibly via a semi-closed position. The lid has a free edge, with a liquid passage opening allowing liquid passage when the lid is in said closed position. The lid is foldably joined to the body along an arcuate first score line. The lid further has second score lines arranged at respective ends of the free edge, the second score lines connecting the free edge and the first score line so that, when the lid is pushed towards the cup opening, the lid flips into a position inside the cup opening, the movement of the lid being substantially aided by the folding of the lid along the second score lines.
