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.

A thermally insulated sleeve adapted to fit over a cup, the sleeve comprising;
- a sidewall having an inside surface and an outer surface, wherein the sidewall is adapted to seal the sidewall upon itself and to form a seam;
- a thin thermally insulating coating having a controlled thickness, supported by the sidewall, comprising a binder and void containing particles, ranging from 0.1 microns to 200 microns in size, adapted to being restricted by the binder;
- and
- a heat activated adhesive supported by the inside surface of the sidewall for bonding the sleeve to the cup.
A blank adapted to the manufacture of a thermally insulated sleeve which is adapted to fit over a cup having a conical shape, the blank comprising;
- a sidewall having an inside surface and an outer surface, wherein the sidewall is adapted to seal the sidewall upon itself and to form a seam;
- a thin thermally insulating coating having a controlled thickness, supported by the sidewall, comprising a binder and void containing particles, ranging from 0.1 microns to 200 microns in size, adapted to being restricted by the binder;
- and
- a heat activated adhesive supported by the inside surface of the sidewall for bonding the sleeve to the cup.
