ABSTRACT:
A one piece pizza tray blank having a generally planar member and a pair of sidewalls capable of being folded upward therefrom. Each of the sidewalls has a pair of opposing extensions capable of being folded inward therefrom along vertical extension fold lines. Each of the extensions has a foot extending downward therefrom in the direction of the planar member. The feet are designed to lockingly engage with slots and pressure tabs in the corner regions of the planar member for lockingly engaging the sidewalls and extensions in a vertical position. The feet also act as supports to prevent the planar member holding a pizza from contacting a counter or table top upon which it may be placed. This pizza tray may be slid inside of an appropriate bag for pizza transport.
