A beverage container is provided with an integral cooling element to maintain a beverage at a cooled temperature after exposure to a warmer environment. The cooling element incorporates use of solid/liquid phase change material. When the beverage is chilled, the phase change material is maintained in a solid state below its melting temperature. When the beverage container is exposed to a warmer environment, such as during consumption, the phase change material undergoes a phase change thereby absorbing heat from the surrounding beverage. The cooling element can either be attached to the inside of the container or free-floating, but in either case, is in direct contact with the beverage.

1. A beverage container with integral cooling capability, said container comprising: a sidewall, a base connected to the sidewall, and a top forming an upper portion of the container;a cooling element placed within the container and at least contacting an interior surface of the sidewall or base, said cooling element comprising a body containing phase change material therein wherein the phase change material undergoes a phase change from a solid to a liquid when absorbing heat from a beverage in the container; andsaid body further includes a plurality of extensions extending away from said peripheral edge and said extensions contacting said interior surface of the sidewall. 2. A container, as claimed in claim 1, wherein: said extensions are fin shaped. 3. A container, as claimed in claim 1, wherein: said extensions each include a base portion connected to said body of the cooling element and a pointed distal tip extending from the base portion, said distal tip contacting said interior surface of the sidewall. 4. A beverage container with integral cooling capability, comprising: a sidewall, a base connected to the sidewall, and a top forming an upper portion of the container;a cooling element placed within the container and at least contacting an interior surface of the sidewall or base, said cooling element comprising a body containing phase change material therein wherein the phase change material undergoes a phase change from a solid to a liquid when absorbing heat from a beverage in the container; andwherein said phase change material includes at least two different phase change materials and wherein each phase change material has a different melting point. 5. A container, comprising: a sidewall, a base connected to the sidewall, and a top forming an upper portion of the container;a cooling element placed within the container and at least contacting an interior surface of the sidewall or base, said cooling element comprising a body containing phase change material therein wherein the phase change material undergoes a phase change from a solid to a liquid when absorbing heat from a beverage in the container; andsaid body of said cooling element has upper and lower surfaces, and said lower surface being curved shape to conform to an exterior dome shaped panel of said base of said container. 6. A beverage container, comprising: sidewall, a base connected to the sidewall, and a top forming an upper portion of the container;a cooling element placed within the container and at least contacting an interior surface of the sidewall or base, said cooling element comprising a body containing phase change material therein wherein the phase change material undergoes a phase change from a solid to a liquid when absorbing heat from a beverage in the container;said body has an irregular shaped peripheral edge, and irregular shaped upper and lower surfaces. 7. A beverage container, comprising: sidewall, a base connected to the sidewall, and a top forming an upper portion of the container;a cooling element placed within the container and at least contacting an interior surface of the sidewall or base, said cooling element comprising a body containing phase change material therein wherein the phase change material undergoes a phase change from a solid to a liquid when absorbing heat from a beverage in the container;said cooling element has a disc shaped body and said body has a circular shaped peripheral edge that contacts said interior surface of said sidewall. 8. A beverage container with integral cooling capability, said container comprising: a sidewall, a base connected to the sidewall, and a top forming an upper portion of the container;a cooling element placed within the container and at least contacting an interior surface of the sidewall or base, said cooling element comprising first and second sheets of flexible plastic film sealed to one another along a peripheral edge, and phase change material encapsulated therein. 9. A container, as claimed in claim 8, wherein: said flexible plastic film is non-permeable and prevents migration of the beverage within the beverage container from contacting the phase change material. 10. A method of maintaining a beverage within the container at a desired temperature, said method comprising the steps of: providing a beverage container having an interior surface;placing a cooling element within the container wherein the container holds a beverage in direct contact with the cooling element, said cooling element having a phase change material;maintaining the beverage in a cooler environment wherein the phase change material is maintained in a solid state;removing the beverage from the cooler environment to a warmer environment, such as when a consumer is consuming the beverage; andwherein said phase change material undergoes a phase change from a solid to a liquid and the phase change material absorbs heat from the surrounding beverage within the container thereby maintaining the beverage at a cooler temperature during the phase change; andwherein said phase change material includes at least two different phase change materials, each having different melting point temperatures. 11. A beverage container with integral cooling capability, said container comprising: a sidewall, a base connected to the sidewall, and a top forming an upper portion of the container;a cooling element placed within the container and at least contacting an interior surface of the sidewall or base, said cooling element comprising a frame with a plurality of gaps formed between extensions of the frame, and a plurality of phase change elements secured between said gaps, said phase change elements having an outer protective covering and phase change material placed therein, said frame having a peripheral edge that contacts an interior surface of the sidewall. 12. A beverage container, as claimed in claim 11, wherein: said outer covering is non-permeable with respect to the beverage thereby preventing migration of the beverage into the cooling element. 13. A beverage, as claimed in claim 1, wherein: said phase change material is selected from the group consisting of paraffin-based waxes and hydrated salts.
