ABSTRACT:
The present invention relates to an insulated container used for example as a cooler box, a thermos flask or an insulated lunch box, a suitable insulating material for such a container and a method for its manufacture. The insulated container of the present invention is made with an insulating layer between inner and outer walls of a double walled container with the inner and outer walls joined together as one, and has an insulating material, made by filling a bag with a low thermal conductivity gas comprising at least one of gases such as Xenon, Krypton and Argon, disposed between the inner and outer walls. The method of manufacturing the insulated container involves the steps of inserting a bag into the space of the double walled container, filling the bag inserted into the space with a low thermal conductivity gas, and then sealing the bag.
