ABSTRACT:
A portable container for heating and storing pizza includes a fabric box about 20 inches long, about 20 inches wide, and about 8 inches high supported in its four vertical corners by plexiglass strips positioned inside sleeves. A lower rigid panel located at the bottom of the fabric box is used to support a heating unit. An upper rigid panel located above the heating unit forms a compartment with the sides and top of the fabric box large enough to contain two pizzas in their delivery box containers. The heating unit includes an aluminum pan which contains a block of insulation having a one-half inch depression in its upper surface. A silicon rubber heating element is positioned inside this depression. The temperature inside the portable container is maintained between 165.degree.-180.degree. F. The portable container can be carried with one hand when used for delivery of hot pizzas.
