Abstract
A thermally insulated sleeve is adapted to fit over a cup. The sleeve has a sidewall having an inside surface and an outer surface. The sidewall is adapted to seal the sidewall upon itself and to form a seam. A thin thermally insulating coating having a controlled thickness is supported by the sidewall. The thin thermally insulating coating is comprised of a binder and void containing particles, ranging from 0.1 microns to 200 microns in size, adapted to being restricted by the binder. A heat-activated adhesive is supported by the inside surface of the sidewall. When the sleeve is heated the heat activated adhesive bonds the sleeve to the cup.
