Abstract
Abstract This invention relates to food and beverage containers and more particularly to containers of the thermodynamic type capable of regulating the temperature of the food and beverage therein. The thermodynamic container disclosed herein comprises an outer wall of low thermal conductivity separated by an insulating material from an inner metal capsule of very high thermal conductivity having a heat-storage material disposed therein. Beverages too hot to drink melt the heat-storage material which in turn cools the beverage to a drinkable temperature within two minutes. Heat lost during the beverage''s cooling is then returned to the beverage to maintain it at a drinkable temperature as the heatstorage material resolidifies.
