A foldable, resilient plate lid of paperboard or the like, having a central panel surrounded by four side panels glued together at overlapping end flap portions to form a continuous skirt which, when open, flares obliquely downwardly from the central panel to encompass the rim of a disposable plate. Opposed rim-receiving slots are formed in at least tow of the side panels. Initially, for gluing, the latter two side panels are folded inwardly under the central panel while the other two panels remain unfolded except for their end flaps, so that upon subsequent opening of the skirt to cover a plate, resilient bias forces urge the initially folded side panels into secure engagement with the rim.

A container for food or the like, comprising (a) a disposable plate having opposed convexly arcuate edge portions, and (b) a unitary lid of foldable, resilient sheet material for overlying the plate and engaging the edge portions thereof, formed from an initially flat sheet blank and including a flat central panel and a skirt which is manipulable between a first, unstressed position and a second, open position wherein the skirt flares obliquely outwardly and downwardly from said central panel for surrounding the periphery of the plate, said skirt comprising four side panels integral with and disposed in succession around the periphery of the central panel, said side panels being arranged in two opposed pairs, each of said side panels having an outer edge, opposed cut end edges, and opposed foldable end flaps, the end flaps of each side panel of one of said pairs being respectively overlappingly adhered to adjacent end flaps of the side panels of the other of said pairs, the side panels of said one pair respectively having slots for receiving said plate edge portions and being disposed, in the unstressed position, with their respective outer edges below the central panel and spaced inwardly from their locations in the open position, and the side panels of said other pair being disposed, in the unstressed position, with their respective outer edges spaced outwardly from their locations in the open position, such that upon outward bending of said one pair of side panels, the side panels of said other pair are bent inwardly toward each other and, in resisting such bending, exert on said one pair of panels a force for urging them into secure engagement with the plate edge portions; (c) said plate being of planar, circular configuration and said skirt being dimensioned, when in said second position overlying and engaging the edge portions of the plate, to enclose with clearance an article of food such as a pizza or the like lying on the plate.
