ABSTRACT:
A container is provided which can be designed to heat its outer surface as to sterilize it, or to heat its inner surface and any contents therewithin. In a container that self sterilizes its outer surface, the container includes a combustible layer of thermit-type pyrotechnic material which can be ignited to generate considerable heat, and a thin casing around the combustible layer which is of highly thermally conductive materials such as aluminum which can be heated to a high temperature by the ignited combustible layer. A buffer layer which may be of metal, lies within the combustible layer, and a layer of insulation such as Teflon lies within the buffer layer to insulate the contents of the container from the heat. The thicknesses of the thermit-type charge of the combustible layer and of the casing are chosen so that the amount of heat from the charge heats the casing to a temperature which is only moderately high to avoid melting the casing.
