  Verfahren zur Herstellung becherförmiger Flasehenkapseln aus Metallfolie. 



   Es ist bekannt, becherförmige Flaschenkapseln aus einem kreisförmigen Blatt aus Metallfolie, z. B. Stanniol, durch Anbringung radial laufender Stehfalten zu formen, auf den Flaschenhals aufzu- schieben und sodann die Stehfalten um den Flaschenhals herum zu Quetschfalten zusammenzupressen. 



   Derartige Kapseln weisen vor ihrer Aufbringung auf den Flaschenhals den Nachteil auf, dass die vor- bereiteten Kapseln ziemlich empfindlich sind, indem die unvermeidlichen Handhabungen mit den
Vorratskapseln zu Quetschungen führen, die die Form der Falten beeinträchtigen und die nachherige
Umbildung zu guten Quetschfalten erschweren. 



   Das Verfahren gemäss der Erfindung besteht nun darin, dass die Stehfalten der in bekannter
Weise hergestellten Kapseln vor dem Aufsetzen auf den Flaschenhals auf einem Dorn od. dgl. zusammen- gepresst, also zu Quetschfalten umgeformt werden. Derart ausgebildete Kapseln besitzen den Vorteil, dass sie auch vor ihrer Verwendung gegen Verquetschung wenig empfindlich sind und wie Kapseln mit stehenden Falten sich während der Anbringung am Flaschenhals infolge ihrer Steifheit nicht schief stellen. Sie lassen sich ferner fester um den Flaschenhals schliessen und ergeben eine Mantelfläche, die genügend glatt und fest ist, um mit reliefartigen Zeichen od. dgl. versehen werden zu können. 



   In der Zeichnung ist der Hergang der erfindungsgemässen Herstellung von   Flaschenkapsln   veranschaulicht. Fig. 1 zeigt eine Kapsel mit den   üblichen   Stehfalten, Fig. 2 einen Schnitt nach der Linie 11-11 der Fig. 1, Fig. 3 die fertige Kapsel, Fig. 4 einen Schnitt nach der Linie   IN-IN   der Fig. 3. Die Fig. 5 und 6 zeigen Werkzeuge zur Herstellung von Kapseln mit verschiedener Kegelgestalt. 



   Zur Durchführung des   erfindungsgemässen   Verfahrens wird von einer Kapsel gemäss Fig. 1 ausgegangen, die aus einem kreisförmigen Blatt einer Metallfolie ausgeformt ist und nebst dem glatten Boden 3 den in Stehfalten 4 gelegten Mantel 2 aufweist. Der so hergestellte   Hohlkörper.'2,   3 wird auf einen Dorn 6 gestülpt und samt diesen in eine Matrize 7 eingeführt, um die Falten   4   zu Quetschfalten zusammenzupressen, wodurch eine Kapsel nach Fig. 3 mit glattem Boden 3 und glatt zusammengepresstem Mantel 8 gebildet wird. Um dem Zuwachs der Wandstärke Rechnung zu tragen, der beim Zusammenpressen der Falten auftritt, weist der Dorn 6 gegenüber der Matrize 7 einen kleineren Winkel am Scheitel auf.

  Process for the production of cup-shaped bottle capsules from metal foil.



   It is known to make cup-shaped bottle caps from a circular sheet of metal foil, e.g. B. tinfoil, to be formed by applying radially running standing creases, pushing it onto the bottle neck and then compressing the standing creases around the bottle neck to pinch folds.



   Such capsules, before they are applied to the neck of the bottle, have the disadvantage that the prepared capsules are quite sensitive, in that the unavoidable handling with the
Storage capsules lead to bruises, which affect the shape of the folds and the subsequent
Make it difficult to transform into good pinch folds.



   The method according to the invention now consists in that the standing folds in the known
Capsules produced in this manner are pressed together on a mandrel or the like before being placed on the bottle neck, that is to say formed into pinch folds. Capsules designed in this way have the advantage that they are not very sensitive to squeezing even before they are used and, like capsules with standing folds, do not tilt when they are attached to the bottle neck due to their rigidity. They can also be closed more tightly around the bottle neck and result in a jacket surface which is sufficiently smooth and firm to be able to be provided with relief-like characters or the like.



   In the drawing, the course of the production of bottle caps according to the invention is illustrated. 1 shows a capsule with the usual standing folds, FIG. 2 shows a section along line 11-11 in FIG. 1, FIG. 3 shows the finished capsule, FIG. 4 shows a section along line IN-IN of FIG. FIGS. 5 and 6 show tools for producing capsules with various cone shapes.



   To carry out the method according to the invention, a capsule according to FIG. 1 is assumed, which is formed from a circular sheet of metal foil and, in addition to the smooth bottom 3, has the jacket 2 laid in standing folds 4. The hollow body 2, 3 produced in this way is placed on a mandrel 6 and inserted together with this into a die 7 in order to compress the folds 4 into pinch folds, whereby a capsule according to FIG. 3 with a smooth bottom 3 and a smoothly compressed jacket 8 is formed . In order to take account of the increase in wall thickness that occurs when the folds are pressed together, the mandrel 6 has a smaller angle at the apex with respect to the die 7.
