ABSTRACT:
A disposable food tray and container system formed of at least a pair of container elements generally having an overall circular contour. The container elements include a central substantially planar member joined in one-piece formation to a rim element extending around the periphery of the planar section. The rim element has upper and lower elements with discrete apertures formed therethrough. The upper and lower rim elements are matingly interfaceable in order to provide a box-like structure. Upper and lower apertures may be aligned in a varying manner by slidable rotation of one element on another subsequent to the nesting interfacing and locking construction. By providing varying sizes of through openings determined by the position of the upper and lower apertures, the venting of vapors contained within the system may be adjusted as to the rate of dispersal to the environment. The upper and lower elements or sections of the rim element includes bead or lug members on an upper surface and a recess formed within a lower surface. The bead or lug members of one rim element are insertable within the recess of a second rim element to provide the nesting interface when the system is used as a box-like container. When the container elements are utilized alone, they may be used as a tray for consuming edible material at the site of a commercial establishment. When used as a box-like structure, the system may be used to transport material contained therein to a remote site.
