a thermally insulated disposable container for pizzas , pies or other round , flat food items is formed of a unitary sheet of plastic foam material with lower and upper sections each formed with a round flat member and a drafted side wall . an integral , flexible hinge connects a portion of the rim of each of the upper and lower sections , so that the sections can be closed with the pizza or other food item contained inside . tabs which extend from the side walls of the container carry a velcro or similar filament pile engaging material to permit the upper and lower sections to be releasably close to one another by the tabs and the engaging materials . in one version , radial ribs in the lower section divide the same into wedge - shaped compartments so that pie wedges of different types of pies can be kept segregated from one another .
