Embodiment Construction

[0024]One embodiment of the present invention is a coffee cup. Such an embodiment can be used for coffee or any liquid that is desired to be brought into and maintained within a desired temperature range. The cup rapidly cools the coffee or liquid by employing phase change materials (PCMs) to help manage the temperature of the coffee. The phase change materials are placed within an insert adapted to be inserted into the cup. Additional phase change materials can be placed inside the cup walls, such as disclosed in U.S. Pat. No. 6,634,417, incorporated herein by reference.

[0025]Cup embodiments of the present invention include phase change material in an insert or inserts designed to be placed within the interior of the liquid cavity of the cup. The insert can be of several different designs but each design increases the amount of surface area that is between the coffee and the PCM (as compared to PCM in the walls of the cup alone) thereby increasing the thermal transfer between the h...

Abstract

A thermal receptacle having a side wall which has an inner surface and a spaced outer surface. An interstitial chamber may be defined by the space between the inner and outer surfaces. A phase change material containing insert is provided into the receptacle. The insert contains a phase change material or a plurality of different phase change materials. Phase change material may also be located within the interstitial chamber. The phase change material regeneratively absorbs thermal energy from a hot liquid in the receptacle thereby rapidly lowering the temperature of the liquid and then the material releases the thermal energy back to the liquid to maintain the temperature of the liquid.

Description

RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application Ser. No. 61 / 583,888, filed Jan. 6, 2012, and incorporated herein by reference.TECHNICAL FIELD[0002]The subject invention relates generally to liquid receptacles or containers and more specifically to a receptacle having a phase change material insert and which rapidly cools a hot liquid (or heats a cold liquid) to a desired range and then maintains the fluid in the desired range for an extended period.BACKGROUND OF THE INVENTION[0003]There have been many attempts in the past to maintain liquids and solids within certain temperature ranges. Hot beverages are usually prepared and served at temperatures well above the desired temperature range of consumption. Typically, the consumer must wait some time before the beverage to sufficiently cool before drinking it. Some impatient consumers will attempt to drink the beverage too soon resulting in burns to the mouth. Similarly, if the drink is spil...
