Abstract
A soft-sided, collapsible insulative container having a flexible casing, a base, peripheral sidewalls extending from the base, and a lid. The sidewalls fold upward from the base at a fold hinge and releasably attach at their vertical edges to form an enclosure. The lid fits the top of the enclosure. Each of the sidewalls, the base and the lid are formed of a sealable pocket having a compressible insulation lining for receiving block insulation. The flexible casing extends tightly around the container in a fully-closed position, exerting a uniform pressure on the container to improve the thermal seals.
Claims22
A collapsible insulative container comprising:
- a base;
- side walls extending from the base;
- and
- a lid;
- wherein the side walls fold upward from the base at a fold hinge, the side walls releasably attaching to each other at vertical edges to form an enclosure having a top opening;
- wherein the lid is sized to fit the top opening;
- and
- wherein the side walls, the base and the lid each comprise a pocket with a pocket opening, the pocket opening for removably receiving block insulation.
A thermally insulative container comprising:
- a base;
- side walls extending upward from the base to form an enclosure having a top opening;
- and
- a lid sized to fit the top opening;
- wherein the side walls, the base and the lid each comprise:
- a pocket with a closeable pocket opening;
- and
- a vacuum panel removably received within the pocket.
A collapsible thermally insulative container comprising:
- a base;
- side walls folding upward from the base at a fold hinge, the side walls releasably attaching to each other at vertical edges to form an enclosure having a top opening;
- wherein the side walls, the base and the lid each comprise:
- a pocket;
- and
- a vacuum panel received within the pocket.
A collapsible insulative container comprising:
- a base;
- side walls extending from the base, the side walls releasably attaching to each other at edges to form a collapsible enclosure having a top opening;
- a lid sized to fit the top opening;
- the base, side walls and lid in an assembly position meeting at thermal junctions;
- and
- a flexible casing secured to at least one of the lid and the base and releasably attachable relative to the other of the lid and the base, the flexible casing sized to fit around the sidewalls in an assembled position, the flexible casing releasably attaching to exert pressure on the thermal junctions.
A collapsible insulative container comprising:
- a base having an upper surface and a lower surface with a depth therebetween which contains block insulation;
- side walls each connected to the base by a flexible hinge, the side walls releasably attaching to each other at adjacent edges to form an enclosure having a top opening, each of the side walls comprising block insulation;
- and
- a lid sized to fit the top opening;
- wherein the flexible hinge for at least one side wall allows the side wall to fold flat against the upper surface of the base, and wherein the flexible hinge for at least one adjacent side wall allows that adjacent side wall to fold flat against the lower surface of the base.
