Description

Verfahren zur Herstellung von Zinkbechern, insbesondere für elektrische Taschenlampenbatterien. Die Herstellung der Zinkbecher für elektrische Taschenlampenbatterien geschieht in der Weise, daß die Längsnaht des Zylinders gelötet oder geschweißt und der Boden gleichfalls eingelötet oder elektrisch eingeschweißt wird. Diese Herstellungsart ergibt Zinkbecher, die bei der Massenherstellung vielfach undicht sind.Process for the production of zinc cups, in particular for electric ones Flashlight batteries. The manufacture of zinc cups for electric flashlight batteries happens in such a way that the longitudinal seam of the cylinder is soldered or welded and the bottom is also soldered in or electrically welded in. This manufacturing method results in zinc cups, which are often leaky in mass production.

Dieser Mangel soll durch den Gegenstand der Erfindung beseitigt werden. Das Wesen der Erfindung besteht darin, daB der Boden des Zinkbechers auf den zylindrischen Teil aufgepreßt und dann in den Innenteil des Bodens eine leicht schmelzende, harzartige Masse eingestreut wird, die nach dem Erwärmen den Boden ankittet und gleichzeitig elektrisch isolierend wirkt.This deficiency is intended to be eliminated by the subject matter of the invention. The essence of the invention is that the bottom of the zinc cup is on the cylindrical Part pressed on and then in the inner part of the bottom a slightly melting, resinous Mass is sprinkled, which cementes the floor after heating and at the same time acts electrically isolating.

Das Verfahren zur Herstellung der Zinkbecher geschieht folgendermaßen Der zylindrische Teil wird durch Schweißen bzw. Löten der Längsnaht gebildet oder aus nahtlos gezogenen Rohren hergestellt. Der besonders hergestellte Boden wird- auf den zylindrischen Teil aufgezogen oder in denselben eingesetzt, und zwar derart, daß die Außenwände bündig liegen. Die Verbindung zwischen Boden- und Seitenteilen geschieht durch Verschmelzen mit einer Isoliermasse, z. B. Holzpech. Die harzige Masse wird in einer dünnen Schicht in das Innere eingestreut. Die Höhe der Schicht beträgt z. B. z bis 2 mm. Die so vorbereiteten Becher werden der Einwirkung der Wärme so lange ausgesetzt, bis die Masse geschmolzen ist. Nach dem Erkalten bildet die Masse eine gute, dichte Verbindung des Bodens mit dem zylindrischen Teil. Dabei hat sich gezeigt, daß die Isoliermasse beim Schmelzen auch entlang dem etwa vorhandenen Schweiß- oder Lötnähten sich ausbreitet und diese dadurch vollkommen dichtet. Ferner hat das Verfahren noch den Vorteil, daß der Boden der darnach hergestellten Zinkbecher nicht besonders isoliert zu werden braucht.The process for making the zinc cups is as follows The cylindrical part is formed or by welding or soldering the longitudinal seam made from seamlessly drawn tubes. The specially manufactured floor is drawn onto or inserted into the cylindrical part in such a way that that the outer walls are flush. The connection between bottom and side parts is done by fusing it with an insulating compound, e.g. B. pitch. The resinous one A thin layer of mass is sprinkled inside. The height of the layer is z. E.g. up to 2 mm. The cups prepared in this way are subject to the action of the Exposed to heat until the mass has melted. Forms after cooling the mass a good, tight connection of the soil with the cylindrical part. Included it has been shown that the insulating compound also along the possibly existing when melting Welding or soldering seams spreads out and thus seals them completely. Further the method still has the advantage that the bottom of the zinc cups produced in accordance with it need not be particularly isolated.

PATENTANSPRUCH: Verfahren zur Herstellung von Zinkbechern, insbesondere für elektrische Taschenlampenbatterien, dadurch gekennzeichnet, daß nach dem Auf- bzw. Einsetzen des Bodens auf den zylindrischen Teil das Innere des Bodenteils mit einer leicht schmelzenden, elektrisch isolierenden Masse, z. B. Holzpech, in dünner Schicht bestreut und dann erwärmt wird, so daß sie schmilzt und den Boden des Gefäßes mit dem zylindrischen Teil dicht und elektrisch isolierend verbindet. PATENT CLAIM: A method for the production of zinc cups, in particular for electric flashlight batteries, characterized in that after the placement or insertion of the bottom on the cylindrical part, the interior of the bottom part with a slightly melting, electrically insulating compound, for. B. pitch, sprinkled in a thin layer and then heated so that it melts and connects the bottom of the vessel with the cylindrical part tightly and electrically insulating.
