 o sind in Schlitzen eines   Rohrstuckes f geführt, gegen   dessen Rand die   Bodenwölbung   der   Flasche stosst,   auf diese Weise das Aufschieben begrenzend.

 auftrifft, der erweiterte Flaschenrand aus dem Spiegel des Zinkbades   herausragt,   so dass kein Zink in das Flascheninnere treten kann. Dieser Rand wird dann mit dem   Flascheninneren     zusammen   verzinnt. 



   Mit Hilfe dieser Eintauchvorrichtung vollzieht sich das Aussenverzinken solcher Flaschen ausserordentlich rasch, einwandfrei und unter geringstem Aufwand von Arbeitskräften. Nach genüfgendem Abkühlen der Flaschen erfolgt die Innenverzinnung in der in der Einleitung erwähnten   Weise durch Ein-   spritzen von flüssigem Zinn mittels Luft unter Druck. Um bei diesem Verfahren des   Aussenverzinkcu,   durch Eintauchen und des Innenverzinnens durch Einspritzen auf alle Fälle ein Oxidieren der gebeizten

 hüten, ist es vorteilhaft, vor dem   Eintauchen in   das Zinkbad eine vorläufige   Innenverzinnung mit einer   nur hauchartig dünnen Zinnschicht durch das Einspritzverfahren vorzunehmen.

   Zwar schmilzt dieser vorläufige Überzug bei der   Aussenverzinkung,   hält aber wegen seiner Feinheit die Innenwand der Blechflasche bedeckt, so dass sich ein Nachbeizen durch Säureeinspritzen erübrigt. Ausser für Flaschen ist dies Verfahren auch für kleinere Kannen oder büchsenartige Gefässe anwendbar. 



   PATENT-ANSPRÜCHE : 
 EMI2.4 
 gekennzeichnet, dass die Innenverzinnung durch Einspritzen flüssigen Zinnes mittels   Luft unter Druck   und vorher die Aussenverzinkung durch Eintauchen der Flaschen in aufrechter Stellung bis nahe dem Rand in ein Zinkbad erfolgt.

 hits, the extended edge of the bottle protrudes from the mirror of the zinc bath, so that no zinc can enter the inside of the bottle. This rim is then tinned together with the inside of the bottle.



   With the help of this immersion device, the external galvanizing of such bottles takes place extremely quickly, properly and with the least amount of labor. After the bottles have cooled down sufficiently, the internal tin-plating is carried out in the manner mentioned in the introduction by injecting liquid tin with air under pressure. In this process of external galvanizing, by dipping and internal tin-plating by injection, the pickled ones are in any case oxidized
 EMI2.3
 be careful, it is advantageous to carry out preliminary internal tinning with an only thin layer of tin using the injection process before immersing it in the zinc bath.

   Although this temporary coating melts during the external galvanizing, its delicacy keeps the inner wall of the metal bottle covered, so that pickling by acid injection is not necessary. In addition to bottles, this method can also be used for smaller jugs or can-like vessels.



   PATENT CLAIMS:
 EMI2.4
 characterized in that the internal tin-plating is carried out by injecting liquid tin by means of air under pressure and the external galvanizing is carried out beforehand by immersing the bottles in an upright position in a zinc bath close to the edge.
