ABSTRACT:
A travel mug has an outer case, an inner case, a film heater, a temperature control device, and a power source connector. The inner case is fitted into the outer case in conjunction with a spacer, thereby resulting in formation of an air space insulation between the inner case and the outer case. The film heater is fastened to the bottom end of the inner case and is connected to an electrical receptacle of the outer case by a wire which is also connected with the temperature control device located in proximity of the film heater. The receptacle is connected to a power source by the power source connector.
