ABSTRACT:
A hot beverage cup and sleeve bring together two modes of heat transfer, conduction and radiation. The sleeve has an inner face with a plurality of high reflectivity surfaces for radiating heat back to the cup. The sleeve also has a plurality of insulating members for containing insulating air. Each of the insulating members is positioned to space the high reflectivity surfaces away from the cup. A low emissivity film can be adhered to the cup without touching the insulating members. The film can also be attached to the sleeve facing but spaced from the high reflectivity surfaces. This cup and sleeve arrangements minimize thermal contact and reduce heat transfer. Thus, the hot beverage cup and sleeve protect a person's hand as well as extend the time of keeping the beverage hot.
