Abstract
The wall of a protective jacket of a vacuum flask, containing a double-walled vessel whose walls are permeable to solar radiation, includes parts capable of being swung open. These parts and a wall part situated between them each have a reflective coating. The reflective surfaces of these coatings, viewed in cross-section, extend along a parabola when the movable wall parts are opened out, so that incident solar radiation is collected in the core zone of the vessel. A solar-radiation absorbing member may be disposed in this core zone, e.g., a metal tube having a black outer surface. Liquid contents of such a vacuum flask can be heated by means of solar energy.
