Patent ID: 8056757

Claim:
A hot beverage cup sleeve adapted for attachment to a hot beverage cup, the sleeve comprising: an outer annular wall having an inner surface and an outer surface, the outer annular wall being adapted for coaxial attachment around a wall of the beverage cup; a plurality of insulating bodies projecting from the inner surface of the outer annular wall, the insulating bodies being spaced apart, defining gaps therebetween, the insulating bodies being adapted for spacing the sleeve outer annular wall away from the cup wall and defining air gaps therebetween; and a plurality of thermally reflective surfaces attached to the inner surface of the outer annular wall in the gaps between the insulating bodies for radiating heat away from the outer annular wall back towards the cup, wherein each said thermally reflective surface is spaced apart from a corresponding pair of said insulating bodies such that a pair of insulating gaps is formed between each said thermally reflective surface and the corresponding pair of said insulating bodies.
