Abstract
Abstract An interlocking plate and cup set for use in casual dining so that one can hold a plate and cup with one hand. The plate and cup mate together so that the cup will be securely held to the plate and so that the mated combination can be placed on and removed from a flat surface without separation. The plate is generally flat and has an upper surface with a raised circumferential edge (12) for restraining food. The upper surface of the plate also has a cup-holding support (20) comprising a slot (24) extending in from the edge of the plate. The slot terminates in a concave cup-support area (22). The cup has a relatively broad base (30), a relatively narrow stem (32) extending up from the base, and a relatively broad liquid-holding body portion (34) extending up fro the stem. The body portion has a convex bottom surface (42) facing downward which is shaped to mate with the cup-support area in the plate. The cup support portion of the plate is spaced from the bottom of the plate and the cup's stem is dimensioned such that (a) the cup can be mated with the plate by inserting the stem of the cup into the slot of the plate until the convex underside of the cups body mates with the concave area of the plate, and (b) when the mated combination is placed upon a flat horizontal surface, it will remain mated.
