Description:
FIELD OF THE INVENTION 
     The invention relates to an improved food and beverage container particularly adapted to be held in one hand. 
     BACKGROUND OF THE INVENTION 
     It is particularly desirable at times for a person to be able to hold a plate of food and a beverage cup in one hand, freeing the other hand for another activity. Guests at social events must attempt to balance a tray of food precariously on the top rim of beverage container in order to free a hand for another activity such as eating, gesturing, or greeting. In utilizing conventional serving means, it is generally necessary to locate a place upon which to set the beverage cup before one can consume the food with ease. Several attempts have been made to alleviate this problem. U.S. Pat. No. 2,920,804 discloses a non-compartmentalized serving plate and glass holder assembly made, of necessity, of rigid materials. A similar, generally triangular design is shown in U.S. Pat. No. Des. 211,532. U.S. Pat. No. 3,955,672 depicts a plate assembly with a channel formed in the lower surface of the assembly to receive the forearm of the user for support of the assembly. 
     DISCLOSURE OF THE INVENTION 
     The present invention provides a mutually supporting tray and drinking cup device particularly suitable for serving food and beverages at fairs, shopping centers, picnics, and other social gatherings. The device comprises an integral food and beverage container that can be stably supported by one hand and includes an upwardly open receptacle for liquids, the receptacle having side walls and a flange extending outwardly from the walls to provide a generally horizontal upper surface suitable for supporting food servings. The container includes ribs extending above the upper surface of the flange and between the flange and side walls to support the flange and to define, with the upper surface of the flange, a plurality of separate, food-receiving compartments.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The container (8) of the invention preferably is formed as an integral piece but, for ease of understanding, the beverage receptacle and flange portions will be described as separate elements. 
     The container of the invention comprises an upwardly open receptacle (12) having outer walls (15). The receptacle (12) may be closed at its bottom to receive a beverage, or may have an open bottom so that the receptacle (12) may receive a separate cup containing a beverage. 
     Extending generally horizontally outwardly from the walls as an integral part thereof is a flange (10), the flange (10) desirably having a circular configuration and an outer, peripheral, upwardly turned rim (11). Although desirably circular in shape, as noted, the flange (10) may be formed with a generally rectangular, square or other configuration (viewed from the top), as may be aesthetically or functionally desired. The flange (10) includes a generally horizontal upper surface upon which food may be supported. 
     A plurality of angularly spaced ribs (13), at least two and preferably four or more in number, extend radially from the rim (11) of the flange (10) to the outer wall of the receptacle (12). Desirably, the ribs (13) are equiangularly spaced and are formed integrally with the flange (10), as by molding. They desirably exhibit an inverted V-shape in cross section, as shown in FIG. 5. Each rib (13) extends radially inwardly from the flange rim (11) to the outer wall of the receptacle (12). The ribs (13), when in contact with the receptacle (12), operate to hold the receptacle (12) and flange (10) together. The ribs (13) also join the outer rim (11) of the flange (10) to the receptacle (12), thus helping to support the weight of the food carried upon the flange (10). Through close contact with the beverage receptacle (12), the ribs (13) also support the beverage receptacle (12) to hold it in place and prevent it from falling through the opening (7) in the flange (10). The ribs (13), the outer wall of the receptacle (12), the upper surface of the flange (10), and the rim (11) define a plurality of separate, upwardly open food receiving compartments (9). 
     Although the ribs (13) have generally been shown as having an inverted &#34;V&#34; cross section, each rib providing support for adjacent sections of the flange, the ribs may take the form of single thickness, continuous or discontinuous webs of material. 
     The serving tray (8) thus described is not meant to be lifted to the lips. Liquid may be removed from the receptacle (12) using a drinking straw (14) or the like. In one embodiment, a drinking cup may be removably received in the receptacle which, in this embodiment, may have an open bottom through which the cup may protrude. The cup, which can be of paper or the like, may be removed from the receptacle and used for drinking. A straw may also be used, enabling the removable cup to remain inside of the receptacle during use. 
     Preferably, the serving tray container is molded or otherwise formed as an integral unit in a disposable or a non-disposable form from polystyrene, paper, plastic or other suitable material. 
     In a preferred embodiment as illustrated in FIG. 1, the walls of the receptacle (12) converge downwardly permitting the container to be easily formed through molding and readily nested with identical containers, providing efficient utilization of storage space. 
     When a food serving is received on the flange (10) of the invention, the ribs (13) support the flange (10) against sagging by exerting forces equal but opposite in direction to the forces exerted on the ribs (13) by the weight of the food serving. Referring to FIG. 6, the force (F1) exerted by the weight of the food acting on the flange is assumed for simplicity and ease of understanding, to act vertically downwardly on the rim (11) of the flange (10). In this loading condition, the upper portion of the rib (16) is in tension and the lower portion (15) of the rib is in compression. An outwardly directed force (F3) is applied to the upper receptacle portion (18) and an inwardly directed force (F5) is applied to the receptacle portion at the intersection of the rib (13), flange (10), and receptacle (12), by the flange (10) and rib (13) combination. These forces, F3 and F5, are opposed by forces F2 and F4 respectively, which are equal in magnitude but opposite in direction and are exerted by the receptacle (12) on the rib (13) and flange (10) combination in the same respective locations, that serve to keep the container in force equilibrium thus preventing the container from collapsing. The ribs (13) also exert force generally vertically upwardly on the adjacent flange (10) to oppose the generally vertically downwardly applied force of a food serving. 
     By utilizing the general configuration shown in FIGS. 1 and 2, the assemblies of the invention can be nested together so that they can readily be stored in an orderly fashion. 
     Because of the support offered by the ribs (13) and the receptacle (12), the flange (10) may be made somewhat thinner and more flexible than plates previously used for picnics and the like, and I contemplate that the serving tray container may be made at a sufficiently low cost as to enable the container to be used once and then thrown away. 
     In another embodiment of the invention illustrated in FIG. 7, the portion of the receptacle (12) that protrudes upwardly above the upper surface of the flange (10) has walls that converge upwardly to restrain liquid in the receptacle from spilling into the flange. Also, a generally vertical, circumferential skirt (24) extends downwardly from the lower surface of the flange (10), at or adjacent its rim (11), the skirt having lower edges (26) which can be carried above, below, or in the same plane as the bottom surface of the receptacle (12). The skirt (24) adds support to the flange (10) by providing a stable base to contact surface upon which the container is placed, helping to prevent the container from toppling over. The skirt (24) may be unbroken throughout its periphery or one or more portions may be removed from it, as shown in FIGS. 8 and 9, to allow a hand to be received therethrough to grasp the receptacle (12). 
     Alternatively, a plurality of posts, preferably at least three in number, could be employed in place of the skirt (24) to add support to the flange (10) and help provide a stable base upon which the container may rest. 
     While a preferred embodiment of the invention has been described, it should be understood that various changes, adaptations and modifications may be made therein without departing from the spirit of the invention and the scope cf the appended claims.
