Description
Gegenstand der Erfindung ist eine Schutzhülle für Thermosgefäße beliebiger Form, wie sie beispielsweise als Flaschen oder topfartige Gefäße auf dem Markt sind. Gefäße dieser Art bedürfen einer Schutzhülle, die bisher aus einem Blechmantel, der in Gummiringen gelagert ist, besteht. Solche Schutzhüllen sind verhältnismäßig leicht zerstörbar, sie leiden besonders unter der durch Kondenswasser sich bildenden Feuchtigkeit.The invention relates to a protective cover for any thermos flasks Shape, as they are, for example, as bottles or pot-like vessels on the market. Vessels of this type require a protective cover, which previously consisted of a sheet metal jacket, which is stored in rubber rings, consists. Such covers are proportionate Easily destructible, they particularly suffer from the condensation that forms Humidity.
Dieser wesentliche Mangel wird erfindungsgemäß dadurch beseitigt, daß man die Hülle aus einem elastischen, direkt auf das Gefäß aufgetragenen, wasserbeständigen Material herstellt.According to the invention, this essential deficiency is eliminated by that you can make the shell from an elastic, applied directly to the vessel, water-resistant Material manufactures.
Solches Material kann erfindungsgemäß aus gemischten Holz- und Gummifasern, die durch ein elastisches Bindemittel zusammengehalten werden, bestehen. Besonders vorteilhaft ist es aber, gemäß der Erfindung die Hülle mehrschichtig herzustellen, und zwar zunächst durch unmittelbares Auftragen einer Klebstoffschicht auf das Gefäß. Darauf wird eine Schicht von imprägniertem Faserstoff, z. B. eine Pappe aufgelegt, dann wieder eine Klebstoffschicht und wieder eine Schicht von imprägniertem Faserstoff usw., bis die gewünschte Hüllenstärke erreicht ist. In beiden Ausführungsformen überzieht man dann die so geschaffene elastische Hülle mit einem schlag- und wasserbeständigen Lack.According to the invention, such material can be made from mixed wood and rubber fibers, which are held together by an elastic binding agent. Particularly however, it is advantageous to produce the casing in multiple layers according to the invention, initially by applying a layer of adhesive directly to the vessel. A layer of impregnated fiber, e.g. B. put a cardboard, then again a layer of adhesive and again a layer of impregnated fiber material etc. until the desired thickness of the hull is achieved. In both embodiments the elastic cover created in this way is then covered with an impact-resistant and water-resistant Paint.
Das Gefäß kann dann an seinem Unterteil mit einem zweckmäßig metallischen Fuß versehen werden, der ebenfalls von der Schutzhülle umfaßt wird.The lower part of the vessel can then be provided with a suitably metallic foot which is also enclosed by the protective sheath.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch veranschaulicht. i ist das Thermosgefäß, 2 ist der Fuß und 3 die Schutzhülle, die in der einen oder anderen Weise gemäß der vorliegenden Erfindung hergestellt ist. Der Fuß 2 wird unten durch einen aus nicht rostendem Material hergestellten Deckel,4 luftdicht abgeschlossen.An exemplary embodiment of the invention is shown schematically in the drawing illustrated. i is the thermos, 2 is the base and 3 is the protective cover, the is made in one way or another in accordance with the present invention. The foot 2 is at the bottom by a cover made of rustproof material, 4 hermetically sealed.
