Abstract

Abstract A portable heat treatment system in accordance with this invention includes a heating shoe having a heat conductive base member and heating means for transmitting heat along the base member. A heat conductive container having a base with peripheral walls extending upwardly therefrom defines a heat treating compartment, and the container is removably retained within the heating shoe with the base of the container being supported by the heat conductive base member of the shoe. A packaged, heat conductive container of body-treating material also constitutes part of this invention.
