Description

Verfahren zur Erhöhung der Haltbarkeit von Thermosflaschen, die aus Reinaluminium bestehen Um die Haltbarkeit von Thermosflaschen wesentlich zu erhöhen, werden diese bei dem Verfahren nach der Erfindung aus Reinaluminium hergestellt. Die Verwendbarkeit einer solchen Thermosflasche ist deshalb fast unbegrenzt. Ihre Form kann beliebig sein. Die Erfindung beruht daher in erster Linie auf der Verwendung von Reinaluminium bei dem nachstehend genannten Verfahren, und zwar an Stelle von Glas, das sehr zerbrechlich ist.Method of increasing the shelf life of thermos flasks that are made from Made of pure aluminum To significantly increase the shelf life of thermos flasks, these are produced in the process according to the invention from pure aluminum. The usability of such a thermos bottle is therefore almost unlimited. Her Shape can be any. The invention is therefore primarily based on use of pure aluminum in the process mentioned below, in place of Glass that is very fragile.

Das erfindungsgemäße Verfahren der Herstellung beruht darin, daß die innere Hülle der Thermosflasche vor (lern Zusammensetzen an ihrem äußeren Umfang mit einer Schutzschicht auf galvanischem Wege überzogen wird. Diese Schutzschicht kommt einem Verkupfern oder Vermessingen gleich. Die äußere Hülle der Thermosflasche wird in gleicher Weise an ihrem inneren Umfang behandelt. Diese ütberzüge sollen die Verbindung des Quecksilberdampfes mit dem Metall erleichtern.The inventive method of production is based on the fact that the inner cover of the thermos bottle (learn to assemble on its outer circumference is galvanically coated with a protective layer. This protective layer is equivalent to copper plating or brass plating. The outer shell of the thermos bottle is treated in the same way on its inner circumference. These covers should facilitate the connection of the mercury vapor with the metal.

Es werden dann verfahrensgemäß beide Hüllen am oberen Ende zusammengeschweißt. Die äußere Hülle erhält in ihrem Boden eine kleine Öffnung, durch welche der Quecksilberdampf in den eine Weite von i cm betragenden Hohlraum hineingeblasen wird. Die vorerwähnte kleine Öffnung wird dann ebenfalls durch Schweißung wieder verschlossen.According to the method, both sheaths are then welded together at the upper end. The bottom of the outer shell has a small opening through which the mercury vapor can pass is blown into the cavity with a width of 1 cm. The aforementioned The small opening is then closed again by welding.

Die äußere Hülle wird über dem Boden von diesem getrennt, um ein Ineinanderpassen der beiden Hüllen zu ermöglichen. Der untere Teil wird nach dem Verschweißen der oberen Enden der beiden Hüllen mit dem oberen Teil wieder durch Schweißen verbunden.The outer shell is separated therefrom above the floor so as to fit into one another of the two cases. The lower part is after welding the the upper ends of the two shells are connected to the upper part again by welding.

Die auf diese Weise hergestellten Thermosflaschen können gegebenenfalls mit einer Schutzhülle aus Filz oder Metall versehen werden.Thermoses made in this way can if necessary, provided with a protective cover made of felt or metal.

Das Verfahren erstreckt sich auch auf Wärmebehälter, die für andere Zwecke als Thermosflaschen benutzbar sind.The procedure also extends to warming containers that are used for others Purposes as thermoses are usable.
