<p>The present invention relates to a container equipped with a thermally self regulating heater, applicable in particular for heating substances to be maintained at a highest constant temperature. The container (1) is substantially similar to the thermally insulated containers for pic-nic and it is equipped with a particular self regulating cable (3) of a known type that is preferably placed in the insulated air space of the perimetrical walls forming the tank (11) and it is wound in close proximity round the inner walls (112). The vessels ( R ) containing the substances to be heated and maintained at a suitable highest operating temperature are placed in the inner space (V) of the tank (11) which can be closed by a suitable cover (12). When the self regulating cable (3) is supplied with electric power, the inner space (V) and the substances stored therein are progressively heated. Since the thermal emission of the self regulating cable (3) decreases as the temperature increases, the heating is automatically cut off when it is reached the desired highest temperature. <IMAGE></p> |
