ABSTRACT:
A portable, insulated carrying chest having both hot and cold compartments. Two separate, insulated compartments are provided within a receptacle. Each compartment has its own cover, so that when one compartment is opened, the other is not disturbed, and heat transfer therebetween is minimized. One compartment has a chilling medium, such as a commercially available frozen, enclosed medium. The other compartment has a heating medium, such as a commercially available heating pack comprising a material which emits heat spontaneously upon being exposed to air. Metal carriers are provided for holding two such heating packs against opposing walls of the hot compartment.
