Abstract
A tray formed of a unitary blank of paperboard for supporting food during a heating process. The tray comprises a bottom wall, two side walls, and two end walls with tabs interlocking the side and end walls. Tabs on the end walls project through slits in the bottom wall to form legs which support the wall in an elevated position. Interior flaps in the main wall lock the end wall tabs in place. The tray is set up without the use of adhesive. Apertures in the bottom wall allow fluid, such as water vapor in the form of steam escaping from the heated food, to flow through the tray.
