ABSTRACT:
Self cooling and self heating beverage containers utilizing water, the boiling point of which has been lowered by a vacuum as the working cooling fluid. A dessicant in a separate container sorbs the vapor generated by the boiling water. The sorption of vapor by the dessicant raises the temperature of the dessicant and limits its vapor sorbing abilities. Provision is made to lower the temperature of the dessicant chamber. In one version of the invention the dessicant chamber is constructed of good heat conducting material, and is immersed in a water bath, to lower the temperature of the dessicant chamber. Alternatively, the outside surfaces of the dessicant chamber are coated with a wick like material. Pre-packaged water is provided to wet the coated dessicant chamber surfaces. The dessicant chamber is then cooled by natural evaporation of the water. In a related improvement, a beverage to be heated is used instead of water as the cooling medium. A single unit of the invention can thus serve as both a cooling and heating device.
