Abstract:
1. A package for transporting a temperature sensitive payload comprising: a container defining an interior volume; a plurality of thermal insulation panels contained within the interior volume; and a plurality of different phase change materials within the interior volume and contained within the plurality of thermal insulation panels, with said plurality of different phase change materials being contained within a plurality of hollow panels, with at least a pair of said plurality of hollow panels being adjacent each along one side of a payload volume to define an inner panel adjacent the payload volume and an outer panel separated from the payload volume by the inner panel, with no thermal insulation being positioned between the inner panel and the outer panel, and with a temperature of the phase change material within the outer panel being outside of a predetermined desired temperature range for payload protection, and with the phase change material within the inner panel thermally buffering the payload volume from thermal damage from the phase change material within the outer panel.
