Abstract: A collapsible thermal insulating container (10) includes a bottom wall (14), side wall (16) and integral lid (20). The side wall is formed from hinged panels including fastener strips (36). The container can be disassembled to form a sheet which lies flat in a common plane. All walls and the lid of the container are constructed from a matrix including inner and outer radiant energy reflective laminates (44) and an air trapping laminated foam insulating layer (52) disposed therebetween. A rigidity imparting structural reinforcement layer (56) is also included in the panels of the sidewall, bottom wall and lid.

Abstract: A portable thermal barrier is disclosed for thermally dividing an enclosure. In a preferred form, the barrier includes a flexible thermal sheet formed by two separable sheet forms that may be folded and stored in a holder such as a bag. The sheet forms may be laid out and releasably joined along inside edges to span the enclosure. Outer foldable flaps of the sheet forms are adjustably positionable adjacent wall surfaces of the enclosure to adjust for varying size enclosures. Opposed top and bottom flap sections fold over onto the sheet, such that outward folded surfaces are selectively positioned adjacent top and bottom wall surfaces of the enclosure. Pockets along side flap sections of the sheet forms receive opposed foot plates of extensible load locks. The load locks are manually extendible to secure the thermal sheet in place against the walls of the enclosure.
