Abstract
The present invention provides an insulated container for cooling hot beverages to an acceptable temperature and then maintaining the beverage temperature in an acceptable temperature range for consumption. This invention has an upper reservoir and a lower reservoir surrounding a beverage chamber, the upper and lower reservoirs communicating with one another through at least one passageway having a two-way valve. A liquid located in the lower reservoir is permitted to flow into the upper reservoir through the valve. The thermal liquid removes some of the heat from the hot beverage. After the hot beverage reaches a satisfactory drinking temperature, the liquid is then allowed to flow back through the valve into the lower reservoir. The air in the upper reservoir maintains the beverage at a proper temperature. A method of use is also provided.
