摘要

The double-walled receptacle (1) for hot drinks, soup and suchlike has an inner wall (2) made from a heat conducting material, and an outer wall (4) made from a material which does not conduct heat. The cavity (3) between the inner and outer walls is filled with a liquid via a sealable filling connector (11). The volume of the intermediate cavity corresponds approximately to the receptacle's content of the inner section (7). The inner wall may be installed concentrically or eccentrically to the outer wall.
