ABSTRACT:
A beverage container is disclosed for keeping liquid evenly heated. The beverage container includes a cup, a heating element, and a removable battery power source. The cup has an inner sidewall surface, an outer sidewall surface, an inner bottom surface, and an outer bottom surface. The inner sidewall surface and inner bottom surface are shaped to hold liquid. The heating element is completely enclosed between the inner sidewall surface and the outer sidewall surface. The heating element heats the inner sidewall surface which then heats the liquid. An insulating layer is included between the heating element and the outer sidewall surface to keep the outer sidewall surface cool while the inner sidewall surface is heated. The battery power source is capable of being temporarily secured to the outer bottom surface of the cup and is utilized to keep the heating element energized to a predetermined level while the battery power source is secured to the cup. When the battery power source is removed, the cup is capable of being submerged in water without damaging the cup. When the battery power source is attached, the beverage container is portable.
