A single walled container for storing hot or cold foods or liquids having a layer of insulation comprised of void containing particles held together with a binder applied to the outer part of the sidewall. The insulation layer provides a controlled amount of insulation which is sufficient to prevent pain to the fingers yet it transmits sufficient heat to warn the user of the temperature of the container's contents. The binder may be any thermoplastic or thermoset resin, and other ingredients may be added to the binder to control viscosity, density, or color.

[ We claim:] [1.]1. A thermally insulated sleeve adapted to fit over a cup, the sleeve comprising;a sidewall having an inner surface and an outer surface;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; andwherein the sidewall is adapted to seal the sidewall upon itself and to form a seam.
