Patent ID: 7798706

Claim:
A method for producing a temperature-indicating, thermally insulated container having a single container structure comprising a bottom member and a side wall, at least the side wall having a thermally conducting part and a thermally insulating part, and a temperature indicator, the method comprising the steps of: forming the side wall having an inner surface and an outer surface and the bottom member having an inner surface and an outer surface; providing a material for forming the thermally conducting part; masking an area on the material for forming the thermally conducting part with a mask; laminating, adhering, coating or attaching at least one layer of a material for forming the thermally insulating part on the material for forming the thermally conducting part; removing the mask; affixing the temperature indicator such that it is in the side wall or on the outer surface of the side wall and is visible from outside the container, and such that the temperature indicator is in thermal contact with the thermally conducting part and is affixed in the area on the material for forming the thermally conducting part that was masked in the masking step.
