Abstract: A container is disclosed for storing and transporting vessels containing a composition susceptible to physicochemical alteration upon changes in temperature above or below a specified temperature range. It comprises a first housing having a vessel holder, and a heat sink disposed within the first housing. A second housing encloses the first housing, the second housing is preferably comprised of a metallic material and is of a double-walled construction.

Abstract: A collapsible and reusable shipping container incorporates a series of inner insulated panels and an outer enclosure. The inner insulated panels possess a series of parallel channels, both horizontally configured along the bottom panel and vertically around the side panels, said panels retaining a plurality of heat sinks. A bottom enclosure and bottom panel is in operative communication with the side panels and outer enclosure, the assemblage retained in a closed condition by a top inner panel and top enclosure. The heat sinks cooperate to maintain constant interior temperatures, while a pallet means allows the packed container to be moved and stored.
