Description

Wärmeisolierende Metall-Doppelwandbehälter nach Patent 537 438 Die Erfindung betrifft die Verbesserung und weitere Ausbildung der durch Patent 537438 geschützten Erfindung eines wärmeisolierenden Metall-Doppelwandbehälters.Heat-insulating metal double-walled container according to patent 537,438 The invention relates to the improvement and further development of the invention, protected by patent 537438, of a heat-insulating metal double-walled container.

Das Neue besteht darin, daß das abdichtende Gummiband und die zargenförmigen Ränder gemäß dem Gegenstande des Hauptpatents durch ein dünnes, zwischen zwei ebenen Gefäßrändern eingeklemmtes Vollgummiband ersetzt werden, wodurch die Ausführung verbilligt und die Festigkeit'der Metallgefäßvereinigung erhöht wird.The new thing is that the sealing rubber band and the frame-shaped Edges according to the subject matter of the main patent by a thin, between two flat ones Vessel rims jammed solid rubber band are replaced, whereby the execution cheaper and the strength of the metal vessel association is increased.

Fig. i der Zeichnung stellt einen Längsschnitt, Fig.2 einen Querschnitt und teilweise einen Grundriß des Erfindungsgegenstandes ,dar.FIG. 1 of the drawing shows a longitudinal section, and FIG. 2 shows a cross section and partially a plan of the subject matter of the invention.

Die beiden spiegelnd auspolierten Metallgefäße J und A enden oben in zwei eben gedrehten oder geschliffenen Ringebenen. F', F", zwischen denen ein äußerst dünner Gummiring G einvulkanisiert liegt. Die an der Lötstelle L luftleer gepumpten Gefäße werden durch den Luftdruck stark aufeinandergepreßt, so daß eine dauernde Dichtung mit dem halbfesten Zwischenlageband G zustande kommt.The two mirror polished metal vessels J and A end at the top in two evenly turned or ground ring planes. F ', F ", between which a extremely thin rubber ring G is vulcanized into it. The one at the soldering point L is evacuated pumped vessels are strongly pressed together by the air pressure, so that a permanent seal with the semi-rigid intermediate layer G comes about.

Durch ein falzförmig ausgeschnittenes Gummiband R werden beide Ränder F', F" verkleidet und nach außen hin derart isoliert, daß die obere Bandseite gleichzeitig als Dichtungsfläche für den Verschlußdeekel D oder ähnliche Verschlußmittel dient. Die an den Verschlußmitteln angelenkten BefestigungsstückeB sind an dem das Ganze umhüllenden Zellstoffmantel M befestigt.A creased elastic band R is used to establish both edges F ', F "clad and insulated from the outside in such a way that the upper side of the tape is at the same time serves as a sealing surface for the closure cap D or similar closure means. The fastening pieces B hinged to the locking means are the whole enveloping pulp jacket M attached.

Auch diese Ausführung läßt sich ohne weiteres auf Kühlschränke, Kühlkisten von beliebiger Form o. dgl. übertragen.This version can also be used with refrigerators and cold boxes of any shape or the like. Transferred.
