"A liquid receptacle has an inner vessel for holding a liquid, an insulated outer shell spaced from the Miler vessel, and a chamber defined between the inner vessel and the outer shell. A phase change material is disposed in the chamber for absorbing thermal energy from the liquid and then releasing the thermal energy back to the liquid to maintain the temperature of the liquid. ... The present invention relates generally to liquid receptacles, containers, and accessories for such receptacles that rapidly cool a hot liquid to a warm range and then maintain the liquid in the warm range for an extended period."
