Description

Verfahren zur Herstellung von Blechdosen. Die Erfindung betrifft ein Verfahren zur Herstellung von Blechdosen, insbesondere von Konservendosen, deren Inhalt durch Sterilisieren konserviert werden soll. Sie besteht im wesentlichen darin, daß der an den Rand anschließende zylindrische Teil des Deckels und des Bodens tiefer gezogen und alsdann derart behandelt wird, daß mehrere aneinanderliegende Blechlagen gebildet werden. Dies kann in der Weise geschehen, daß der tiefer gezogene Zylinderteil mit einer oder mehreren Nuten versehen und dann zusammengedrückt wird, so daß er mehrere übereinanderliegende Blechlagen bildet. Es kann ferner auch in der Weise verfahren werden, daß der untere Teil des tiefer gezogenen Zylinders ein oder mehrere Male zurückgezogen wird, so daß er mehrere nebeneinanderliegende Blechlagen bildet.Process for the manufacture of tin cans. The invention relates to a Process for the production of tin cans, in particular food cans, their Contents should be preserved by sterilization. It essentially consists in that the cylindrical part of the lid and the bottom adjoining the edge is drawn deeper and then treated in such a way that several adjacent Sheet metal layers are formed. This can be done in such a way that the more deeply drawn Cylinder part is provided with one or more grooves and then pressed together, so that it forms several superimposed sheet metal layers. It can also be used in be proceeded in such a way that the lower part of the deeper drawn cylinder or is withdrawn several times so that it has several sheet metal layers lying next to one another forms.

Hierdurch soll erreicht werden, daß der an den Rand anschließende Teil des Deckels eine größere Widerstandsfähigkeit und Festigkeit erhält, wie sie für die beim Sterilisieren der Dosen auftretende Beanspruchung des Deckels und des Bodens erforderlich ist, und dies hat zur Folge, daß man Dosen mit derartigen Deckeln und Böden mit genügender Widerstandsfähigkeit auch aus leichterem bzw. weicherem Material, z. B. aus Aluminium, herstellen kann. Das- Verfahren kann auch bei der Herstellung von Dosen Anwendung finden, bei denen Rumpf und Boden aus einem Stück Blech gezogen werden.This is to ensure that the adjacent to the edge Part of the lid is given greater resistance and strength as it does for the stress on the lid and the cans that occur when sterilizing the cans Soil is required, and this has the consequence that you cans with such lids and floors with sufficient resistance also made of lighter or softer Material, e.g. B. made of aluminum. The procedure can also be used in the Manufacture of cans are used in which the body and base are made from one piece Sheet can be drawn.

In der Zeichnung ist die Ausführung des Verfahrens beispielsweise an einem Dosendeckel veranschaulicht. Fig. i zeigt den Deckel nach dem ersten Arbeitsgang, bei weichem der an den Rand a anschließende Zylinder b gezogen wird.In the drawing, the execution of the method is for example illustrated on a can lid. Fig. I shows the lid after the first step, at which the cylinder b adjoining the edge a is pulled.

Fig. 2 zeigt die im zweiten Arbeitsgang angebrachte Nut d und Fig.3 den durch Zusammendrücken derselben fertiggestellten Deckel, welcher drei aufeinanderliegende Blechlagen b1, b2, b3 aufweist. Bei Anbringung von mehreren Nuten in dem Zylinderteil werden durch Zusammendrücken derselben entsprechend . mehr aufeinanderliegende Blechlagen gebildet. Der innere Teil des Deckels ist mit Sicken c versehen.FIG. 2 shows the groove d and FIG. 3 made in the second operation the lid, which is finished by pressing the same together, which has three Has sheet metal layers b1, b2, b3. When making several grooves in the cylinder part by pressing them together accordingly. more sheet metal layers lying on top of one another educated. The inner part of the lid is provided with beads c.

Fig, q. veranschaulicht einen Deckel, bei welchem der untere Teil des Zylinders b zurückgezogen ist, so daß zwei nebeneinanderliegende Blechlagen b4,- b5 gebildet werden, Fig. 5 einen solchen, bei welchem eine nochmalige Zurückziehung des Zylinderteils vorgenommen ist, so daß der Deckel drei nebeneinanderliegende Blechlagen b6, b7, b8 aufweist.Fig, q. illustrates a cover in which the lower part of the cylinder b is retracted so that two sheet metal layers b4, - b5 lying next to one another are formed; b6, b7, b8.
