Insulated beverage container for both heated and chilled liquids

Abstract

The present invention is directed generally to an apparatus to insulate beverage containers, and more particularly to a design which may sustain a temperature gradient over a designed time frame. In a particular embodiment of the invention, the insulated beverage container when housing a chilled liquid beverage initially in the range of 40 degrees Fahrenheit and ambient temperature no more than 80 degrees, the temperature of the liquid beverage will not rise more than 10 degrees over a period of 45 minutes with the insulating cap sealing the top of the beverage container. Similarly, the same insulated beverage container with a heated beverage initially in the range of 170 degrees Fahrenheit, and ambient temperature no less than 20 degrees, the temperature of the liquid beverage may not cool more than 10 degrees over a period of 45 minutes with the insulating cap sealing the top of the beverage container.
