ABSTRACT:
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.
