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...
