1. A temperature-controlled shipper comprising:
a product receptacle comprising first and second phase change material containers, each containing a dual phase change material liquid suspension comprising a first phase change material and a second phase change material combined in a homogenous suspension,
said first and second phase change material containers being received in mated facing relation wherein facing surfaces thereof cooperate to define at least one product receiving cavity therebetween for receiving and enclosing a temperature sensitive product; and
an insulating case comprising first and second insulated clamshell portions received in mated facing relation wherein facing surfaces thereof cooperate to define a cavity for receiving said product receptable, the first and second insulated clamshell portions each comprising a bi-level shape having a high level section and a low level section, the high level section of each insulated clamshell portion having a height greater than its low level section and the high level section of each insulated clamshell portion being configured to mate with the low level section of the other insulated clamshell portion,
said first phase change container being frictionally received within said first insulated clamshell portion, said second phase change container being frictionally received within said second insulated clamshell portion,
each of said first and second insulated clamshell portions comprising a ridge and a shoulder positioned along a perimeter of each of its high and low level sections, the ridges and shoulders of the first insulated clamshell portion being frictionally received in inter-fitting mated relation with the shoulders and ridges of the second insulated clamshell portion to retain said product receptacle and said insulating case in assembled relation.
