ABSTRACT:
A thermally insulated container is provided, mainly intended for storing and transporting material such as vaccine, biological material or the like, which requires storing at a constant temperature during several months. The container comprises an outer and an inner vessel each of which is hermetically sealed and defining an outer and an inner space respectively. The material to be kept at said temperature is arranged in the inner space. A solid-to-liquid phase transforming material is arranged in the inner space completely surrounding said material. A composite insulation fills out the outer space and comprises layers of a porous material under vacuum alternating with layers of a heat reflecting material. The insulation encloses the inner vessel on all sides and the outer space is free from structural connections extending between the inner and outer vessels, so that thermal bridges between the inner and outer vessels are effectively prevented.
