Abstract
The tray is provided with ribs across the base to provide air flow passages under a hot pizza pie or slice to prevent the pizza from becoming soggy. The ribs also serve to stiffen the tray. The wall of the tray may also be provided with vertical ribs. A ledge is provided to receive an imperforate cover and integral protuberances or flanges on the tray secure the cover in place. In one embodiment, the wall of the tray is sloped to facilitate removal of a pizza slice.
