ABSTRACT:
A reusable insulated box includes a shipping container having a plurality of interconnected sides integral with a closed bottom and a sealable top. Bottom, top and side insert members are comprised of a rigid insulating material having at least an inner or outer surface thereof coated with a reflective insulating material for thereby providing a plurality of insulating plate members and each of the insulating plate members is sheathed in a heat shrunk thermoplastic insulating material. The bottom insert member is disposed in facial relation with the closed bottom of the container and the side insert members extend upwardly from a peripheral portion thereof in facial relation with the sides of the container. A top insert member is engaged with and supported by an upper surface of each of the side insert members and the combination of the thickness of the top and bottom insert members with the height of the side insert members is sufficient to permit closing and sealing of the sealable top.
