  Verfahren und Vorrichtung zur Herstellung eines dichten, leicht zu   öffnenden    Behälterverschlusses und nach dem Verfahren hergestellter   Behälterverschlu°.   



     Gegenstand    vorliegender Erfindung ist ein Verfahren zur   Herstellung    eines dichten, leicht zu öffnenden Behälterverschlusses, gemäss welchem man Deckel und Behälterkorpus miteinander verbördelt. Gemäss der Erfindung wird zur Vorbereitung der Trennung von Deckel und   Behälterkorpus    der   letzter, e nach dem Bördeln geschwächt. Diese    Schwächung ist besonders vorteilhaft bei Pappbehältern, wo der hohle Deckel mit konischer Dichtungsfläche nach   Durchschnei-    dung der Schwächung mittels eines gewöhnlichen Messers oder eines andern Gerätes, unter Beibehaltung des dichten Schlusses zwischen den konischen Passflächen, immer wieder abgehoben und aufgesetzt werden   kann.   



   Die Vorrichtung zur Ausübung des Verfahrens, welche mit Falzrollen,   lBalzkopf    und   Falzteller    ausgerüstet ist, hat erfindungsgemäss eine Perforierrolle zum Sehwä  ellen    des Behälters.



     Gegenstand    der Erfindung ist auch der nach dem Verfahren hergestellte Behälterverschluss.



   Beiliegende Zeichnung zeigt   beisriels-    weise in
Fig. 1 in schematischer Weise einen Teil der Vorrichtung, mit welcher das Verfahren ausgeübt werden kann, in
Fig. 2 einen Schnitt durch den fertig hergestellten Verschluss und in
Fig. 3 eine Draufsicht der Perforierkante einer Perforierrolle.



   Der Deckel 1 aus   Pappmaterial    oder aus   hIetall    hat eine konische Passfläche 2, welche bei zusammengebautem Zustande auf einer Passfläche 3 des   Pappbehälterkorpus    4 aufliegt. Der   Behälterkorrus    4 hat einen horizontalen, ringförmigen Rand 14. Auch der Deckel 1 weist einen solchen horizontalen Rand 15 auf, der aussen leicht nach unten umgebogen ist. Der   Deckel    1, der auf den auf den   Faizteller    7 aufgesetzten Behälter  korpus 4 aufgesetzt ist, wird mittels des Falzkopfes 5 dadurch in den Behälterkorpus eingepresst, dass man den Falzteller 7 nach oben   beweg.    Die Passflächen 2 und 3 sind so genau hergestellt, dass schon durch sie allein also ohne Verbördelung, ein absolut dichter Schluss gewährleistet ist.

   Lässt man Falzkopf 5 und Falzteller 7 mit dem Behälter rotieren und fährt mit der Falzrolle 6 gegen den Rand des Deckels, so wird durch Einrollen der Ränder 14 und 15 eine doppelt gefalzte Bördelung gemäss Fig. 3 hergestellt.



   Ist die Bördelung fertig, so fährt man mit der Falzrolle 6   zurück rund    setzt die Perforierrolle 10 an der fertigen Bördelung an. Diese Perforierrolle hat eine Perforierkante 11 (Fig. 3), welche bei Rotation des   Behälterkorpus    unmittelbar unter dem fertigen Bördelrand, also in einem Abstand über dem Deckelboden, im   Behälterkorpus    eine Schwächung 13 herstellt, welche mittels eines gewöhnlichen Messers oder eines andern Instrumentes die Trennung von Behälterkorpus und Deckel leicht und ohne Beschädigung des letzteren erlaubt. Der Deckel kann somit nach seiner Abtrennung wiederholt abgehoben und aufgesetzt werden, und zwar unter Beibehaltung des dichten Schlusses zwischen den   konischen    Passflächen 2 und 3.



  Diese Schwächung wird also vorgenommen, nachdem die Bördelung zu Ende geführt ist; die Rille 16 der Rolle 10 ist daher so tief, dass ihr Grund nicht auf die Bördelung stösst.



     Würde    man die Schwächung vor dem Einführen des Deckels oder noch bei Anfertigung der Hülse vornehmen, so wäre beim Einpressen oder Bördeln des letzteren eine Beschädigung des geschwächten Behälters zu befürchten.



   Auch bei Innenverbördelungen kann die Schwächung   verfahreusgemäss    nach dem Bördeln mittels einer Perforierrolle erfolgen.   



  
 



  Method and device for producing a tight, easy-to-open container closure and container closure produced according to the method.



     The present invention relates to a method for producing a tight, easy-to-open container closure, according to which the lid and the container body are flanged together. According to the invention, in preparation for the separation of the lid and the container body, the last, e, is weakened after the flanging. This weakening is particularly advantageous in cardboard containers, where the hollow lid with conical sealing surface can be lifted off and put on again and again after cutting through the weakening using a conventional knife or other device, while maintaining the tight seal between the conical fitting surfaces.



   The device for carrying out the method, which is equipped with hemming rollers, a scoring head and hemming plate, has, according to the invention, a perforating roller for viewing the container.



     The invention also relates to the container closure produced by the method.



   The accompanying drawing shows, for example, in
Fig. 1 schematically shows part of the device with which the method can be practiced, in
Fig. 2 shows a section through the finished closure and in
Figure 3 is a plan view of the perforating edge of a perforating roller.



   The cover 1 made of cardboard material or made of metal has a conical fitting surface 2 which, when assembled, rests on a fitting surface 3 of the cardboard container body 4. The container body 4 has a horizontal, ring-shaped edge 14. The cover 1 also has such a horizontal edge 15 which is slightly bent downwards on the outside. The lid 1, which is placed on the container body 4 placed on the folding plate 7, is pressed into the container body by means of the folding head 5 by moving the folding plate 7 upwards. The mating surfaces 2 and 3 are manufactured so precisely that they alone ensure an absolutely tight seal without flanging.

   If the hemming head 5 and hemming plate 7 are rotated with the container and the hemming roller 6 moves against the edge of the cover, then a double-folded flange according to FIG. 3 is produced by rolling in the edges 14 and 15.



   When the flanging is finished, the hemming roller 6 is moved back around and the perforating roller 10 starts at the finished flanging. This perforating roller has a perforating edge 11 (Fig. 3) which, when the container body rotates, produces a weakening 13 in the container body immediately below the finished beaded edge, i.e. at a distance above the lid base, which by means of a conventional knife or other instrument separates Container body and lid allowed easily and without damaging the latter. The cover can thus be repeatedly lifted off and placed on after it has been separated, while maintaining the tight seal between the conical fitting surfaces 2 and 3.



  This weakening is carried out after the flanging has been completed; the groove 16 of the roller 10 is therefore so deep that its base does not come into contact with the flange.



     If the weakening were to be carried out before the cover was inserted or while the sleeve was being manufactured, then there would be a risk of damage to the weakened container when the latter is pressed in or crimped.



   In the case of internal crimps, too, the weakening can take place according to the procedure after crimping by means of a perforating roller.
