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. The cup preferably but not necessarily has two secondary fold lines extending from the first score line to the outer edge of the lid portion, near opposite sides of the lid portion, which assists in holding the lid down once closed.
A disposable cup having a body portion and a lid portion, said lid portion extending upwardly from one side of said body portion of the cup when in an open position, and arranged to flip from convex to concave along an arcuate first score line into a position within the body of the cup and across the otherwise open top of the cup when in a closed position, said lid portion having flaps extending laterally outwardly from opposite sides thereof so as to overlie lateral edges of said body portion adjacent opposing areas where said lid portion meets said body portion.
A disposable cup having a body portion and a lid portion, said lid portion being integral with or secured to said body portion to extend upwardly from one side of said body portion of the cup when in an open position, and arranged to flip from convex to concave along an arcuate first score line into a position within the body of the cup and across the otherwise open top of the cup when in a closed position, said cup body having flaps extending laterally inwardly from each side thereof so as to overlie lateral edges of said body portion adjacent opposing areas where said lid portion meets said body portion.
A disposable cup having a body portion and a lid portion, said lid portion being integral with or secured to said body portion to extend upwardly from one side of said body portion of the cup when in an open position, and arranged to flip from convex to concave along an arcuate first score line into a position within the body of the cup and across the otherwise open top of the cup when in a closed position, wherein said lid portion has reinforcement pieces bonded thereto to provide a double layer and therefore added strength to at least portions thereof.
A disposable cup having a body portion and a lid portion, said lid portion being integral with or secured to said body portion to extend upwardly from one side of said body portion of the cup when in an open position, and to flip into a position within the body of the cup and across the otherwise open top of the cup when in a closed position, and at least one primary feature selected from the list comprising the following primary features:
