Abstract
A pizza box having a top and bottom each formed of a single layer of biodegradable, insulating material, such as molded fiber. The bottom provides an insulating airspace between the hot pizza product and the bottom major surface area and another insulating airspace between the bottom undersurface and a resting surface. The top and bottom, when closed, provided a closed chamber with no external air circulation. Thermal conduction paths are reduced by the small surface area contact between the bottom and the product and the small surface contact area between the bottom and a resting surface. Additional features include a closed storage chamber without air vents, a truncated cone or truncated pyramid shape, moisture absorption by the top inner surface, liquid resistance by the bottom top surface, stackable tops and bottoms, air restricting closure walls, cutting channels which also add strength to the bottom and radiation reflective color.
