Abstract: A valve for use with a cap for a spill resistant cup, the cap including a spout to dispense the liquid and a valve mount extending from the spout to engage with the valve. The valve includes a generally cylindrical valve tower extending from a valve base to sealingly engage the valve mount and having an interior bore for the passage of liquid and a valve face sloping across an upper end of the valve tower bore from a higher first point on a first side of the valve tower and to a lower second point on a diametrically opposite second side of the valve tower. A valve mechanism is located in the valve face for controlling a flow of the liquid through the valve mechanism dependent upon a pressure differential across the valve face. The valve mechanism is a valve slit extending through the valve face perpendicular to a mouth opening in the spout and is S-shaped or straight.

Abstract: According to the invention there is drinking cup having a flat bottom and two large diametrically opposed handles. A removable lid with a drinking spout and an air vent is provided to prevent spillage. A separate weighted convex base is attached to the base of the cup to automatically right the cup under the force of gravity. The bottom of the cup and the top of the base are provided with a circular groove and a mating circular ridge. The ridge and the groove positively engaged to align the base horizontally in place on the bottom of the cup while permitting rotation of the base relative to the cup. Two diametrically opposed generally C-shaped clips are located on the edge of the base and extend upwards from the edge of the base and face in opposite directions in order to engaged the handles on the cup upon rotation of the base.

Abstract: A locking apparatus for securing adjacent articulated members such as a toilet seat and lid mounted on a bowl. Included is a plate for mounting the apparatus to the bowl and a locking arm movable with respect to said plate to a position where the leg of the locking arm overlies the lid.

Abstract: A serving dish having a selectively divisible colander member and cover adapted to closure either or both the dish and/or colander.
