Abstract
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.
Claims64
An insulated container comprising:
- a base having an edge;
- a sidewall, having an inner surface and an outer surface, surrounding the base;
- and
- a thin thermally insulating outer coating having a controlled thickness, directly printed on the outer surface of the sidewall, said thin thermally insulating outer coating comprising a binder and void containing particles, ranging from 0.1 microns to 200 microns in size, adapted to being restricted by the binder.
An insulated paper container comprising:
- a base having an edge;
- a sidewall, having an inner surface and an outer surface, surrounding the base;
- and
- a thin thermally insulating outer coating having a controlled thickness, directly printed on the outer surface of the sidewall, said thin thermally insulating outer coating comprising a binder and void containing particles, ranging from 0.1 microns to 200 microns in size, adapted to being restricted by the binder.
An insulated paper container comprising:
- a base having an edge;
- a sidewall, having an inner surface and an outer surface, surrounding the base;
- the inner surface supporting an inner coating adapted to seal the sidewall upon itself and upon the edge of the base;
- a thin thermally insulating outer coating having a controlled thickness, directly printed on the outer surface of the sidewall, said thin thermally insulated outer coating comprising a binder of acrylic resin, and void containing particles ranging from 0.1 microns to 200 microns in size, adapted to being restricted by the binder, and
- a lip formed upon an extremity of the sidewall opposite to the base.
A blank adapted to the manufacture of a paper container having an outer surface, an inner surface, an upper edge, a lower edge, a left edge, and a right edge comprising:
- an inner coating supported by the inner surface, and
- a thin thermally insulating outer coating having a controlled thickness direct printed on the outer surface;
- wherein the outer coating comprises a binder and void containing particles, ranging from 0.1 microns to 200 microns in size, adapted to being restrained by the binder.
An insulated food container comprising:
- a first portions having at least one edge and an outer and an inner surface;
- a flexible web portion being attached to an edge of the first portion;
- a second portion, having at least one edge and an outer and an inner surface, being attached to the web portion so that folding the first portion over upon the second portion defines a volume;
- and
- a thin thermally insulating outer coating having a controlled thickness, directly printed on at least one of said outer surfaces, said thin thermally insulating outer coating comprising a binder and void containing particles adapted to being restrained by the binder.
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 outer coating having a controlled thickness, supported by the outer surface of 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
- wherein the inner surface of the sidewall is adapted to seal the sidewall upon itself and to form a seam.
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 inner surface and an outer surface;
- a thin thermally insulating outer coating having a controlled thickness, supported by the outer surface of 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
- wherein the inner surface of the sidewall is adapted to seal the sidewall upon itself and to form a seam.
