• the space that is evacuated serves this purpose.
• the inner surface of the outer container wall is also mirrored so that the heat emitted by radiation is as low as possible.
• the present invention is based on the object of designing a thermos bottle so that its liquid content can be heated by solar radiation.

• FIG. 6 shows a perspective view of a third embodiment with the protective housing jacket parts folded
• FIGS. 8 and 9 vertical sections of embodiment variants which differ from the first or second embodiment only with regard to the design of an organ used in the container for absorbing the solar radiation,

• FIG. 13 shows a cross section of an embodiment variant of a fold-out jacket part which is equipped with an additional reflector wing which can be pushed out of it.
• thermos shown in Figures 1 to 3 has a double-walled container 1, with an inner wall la and an outer wall 1b, both of which are transparent to solar radiation, the space 2 between these two walls being evacuated.
• the container is immovably inserted in a protective housing, which is made, for example, of plastic and has parts 3 and 4, which are interlocked at 5.
• the cylindrical casing part of the protective housing which surrounds the cylindrical casing part of the container 1, has, as can best be seen from FIG. 2, two hinged casing parts 3a and 3b; these are quite stiff and are hinged together with the intermediate part 3c, opposite which a web 3d is present.
• the hinged jacket parts and the fixed jacket part 3c are provided on the inside with a reflective covering 6 and thus serve as reflectors which, when the jacket wall parts 3a and 3b are opened approximately into the position according to FIG. 2, the incident solar radiation into the interior of the container 1 radiate. If the shell parts 3a and 3b are closed and z in this closed position. 3. are held by a tension lever lock 7 (FIG.
• the reflective coating 6 also serves to insulate the radiation of heat from the container 1.
• the solar radiation which is radiated into the container 1 when the casing parts 3a and 3b are opened, is of course only absorbed by the liquid in the container when this liquid is dark, e.g. B. consists of coffee. So that other liquids can now be heated by the radiation, e.g. B. ordinary clear water, an additional, the solar radiation absorbing organ 8 is arranged in the core zone of the container. This organ is said to be matt black on the outside. It can e.g. B. consist of a fabric stocking or a tube which is placed on a part 9a of a conventional closure 9 for the container 1.
• an overpressure valve 10 is installed in an inner part 9b of the closure 9; such pressure relief valves are provided, for example, in steam cookers and therefore do not need to be described in more detail.
• the unfolded shell wall parts 3a and 3b together with the intermediate shell part 3c form a parabolic cylinder mirror in rough approximation, such that the incident solar radiation is essentially concentrated on the core zone of the container 1, where the radiation-absorbing material is concentrated Organ 8 is located. From this cross section, the mirror image arrangement with respect to the diametrical plane running there vertically can be clearly seen.
• the embodiment according to FIGS. 4, 5 and 6 differs from the embodiment just described mainly with regard to the design of that part of the protective housing which has the hinged jacket parts; this part is designated by 11 and the hinged casing parts belonging to it are designated by 11a and 11b, and the casing part located between them is designated by 11c.

• This Location is determined here by two three-part linkage 12, the parts of which are designated 12a, 12b and 12c; these parts can be of a similar design to parts of an umbrella frame, the two rods extending according to a straight line when the jacket parts 11a, 11b are open, whereas when the jacket parts 11a, 11b are folded, these rods can be accommodated in the intermediate empty space next to the container 1, as is the case here is indicated by dash-dotted lines.
• the hinged jacket parts 11a, 11b have attached carrying handles 11d and 11e, the latter being provided with push-button projections 11f which snap into corresponding holes in the handle 11d. With 11g a housing web corresponding to the web 3d is designated.
• the hinged jacket parts 11a, 11b in the cross-section perpendicular to the longitudinal axis of the container 1 have a length which is a multiple, z. B. is three times the outer diameter of the container 1; this obviously means that more solar radiation can be captured and reflected into the core zone of the container 1, where it is absorbed, for example, by the organ 8 and released to the surrounding liquid.
• the embodiment according to FIG. 7 can be designed similarly to the design of the hinged protective housing shell parts as in one or other of the previously described embodiments.
