Patent attributes
Insulated shipping container and method of making the same. In a preferred embodiment, the insulated shipping container comprises an outer box, an insulated insert, an insulated cover, a payload container and a plurality of coolant members. The outer box comprises a rectangular prismatic cavity bounded by a plurality of rectangular side walls, a closed bottom end, and top closure flaps. The insulated insert is snugly, but removably, disposed within the outer box and is shaped to define a bottom, four sides and a top. The top includes a raised peripheral edge and a recessed shelf. A large rectangular prismatic cavity surrounded by a plurality of smaller cavities extends downwardly from the recessed shelf. The large cavity of the insulated insert is adapted to receive a payload container, together with a pair of coolant saddle bags adapted to surround the payload container. Each of the smaller cavities of the insulated insert has a “top hat” shape when viewed from above, with each of these cavities including a comparatively wider but shorter and shallower section and a comparatively narrower but longer and deeper section. The wider but shorter and shallower section is dimensioned to loosely receive a coolant brick, with the unoccupied portion of the section and the completely unoccupied narrower but longer and deeper section providing air spaces for convection.
