Abstract
A sliding lid is disclosed for use on open top tapered trays having angularly disposed side walls and no top flange. The lid is prepared from a blank of flexible material such as paperboard or the like and comprises a central panel having inside and outside panels and a glue flap foldably attached to each side edge thereof. The inside and outside panels are folded to produce side flaps that are fixed in place when the glue flaps are adhered to the inside of the central panel. In their fixed position, the side flaps are angularly oriented with the lid central panel so as to grip the tapered side walls of the tray when the lid is in place.
