The present invention relates to an insulated electrically heated pot which is provided with an insulated container and an electric heating apparatus disposed therewithin, into which insulated container a liquid such as water or the like is introduced and heated, and the temperature thereof is maintained, as well as to a manufacturing method therefor. In the insulated electrically heated pot in accordance with the present invention, at least one gas having a low conductivity selected from the group consisting of xenon, krypton, and argon is made to fill the insulating layer of the insulated container.

Insulated electrically heated pot and manufacturing method therefor

Cold-hot storage box with inert gas insulating jacket

A thermally insulated cooking device, including an insulated container, a cooking spot suspended inside the insulated cooking container, an insulated outer lid which closes off an upper opening of the insulated container, and an inner lid for closing off an upper opening of the cooking pot. Further included is a heat retaining material that can be heated by microwaves, which is removably attached to an inner face of the insulated outer lid. By attaching the heat retaining material, after it has been heated in a microwave oven, a temperature drop inside the insulated container can be substantially and safely prevented since heat radiates from the heat retaining material into the insulated container. Moreover the heat retaining material can be safely handled.
