An insulating transport and storage container

A thermally insulating transport container comprising:

• a cuboid body comprising six insulating panels;
• and a coolant support member;
• wherein the coolant comprises a solid that sublimates;
• wherein the cuboid panels comprise a base panel, first and second end-wall panels and first and second sidewall panels and a cover panel;
• wherein the insulation panels are fastened such that they provide a substantially gas-tight seal along mutually orthogonal edges;
• wherein the coolant support member comprises at least a support tray spaced, in use, from an inside face of the cover panel, the support tray being provided with upstanding support members;
• wherein a payload volume is defined below the coolant support tray, which payload volume provides sufficient space for a palletized good;
• wherein, in use, once assembled and provided with coolant, the coolant gases emanating from the coolant are operable to cool the payload volume by sublimation;
• and
• wherein a gas valve is provided to enable gaseous pressure control within the cuboid volume due to the sublimation gases arising from the coolant.
