Description

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen von Schrumpfkapseln.The invention relates to a method for producing shrink capsules.

Diese sind dazu bestimmt, bereits mit Stöpsel, insbesondere Korken, verschlossene Flaschen zu umschließen. These are intended to enclose bottles that have already been closed with stoppers, in particular corks.

Es ist bereits bekannt, die Mündung und den oberen Teil des Halses von Flaschen, insbesondere für Wein oder Spirituosen oder Kosmetika mit Kapseln zu versehen, nachdem der Stöpsel oder Korken eingeführt ist.It is already known the mouth and the upper part of the neck of bottles, in particular for To cap wine or spirits or cosmetics after inserting the stopper or cork is.

Zu diesem Zweck sind verschiedene Arten von Kapseln bekannt geworden. Bestens bewährt haben sich Kapseln aus Zinnfolie, weil sich diese faltenlos um den Flaschenhals anbringen lassen. Da diese Staniolkapseln aber sehr kostspielig sind, ist man dazu übergegangen, Flaschenkapseln aus Aluminium herzustellen. Diese Kapseln sind zwar erheblich billiger als die Staniolkapseln, lassen sich jedoch wegen der Sprödigkeit des Metalles ohne Falten zu bilden, schwer auf den Flaschenhals aufbringen.Various types of capsules have become known for this purpose. Have proven to be the best capsules made of tin foil, because they can be attached to the neck of the bottle without creases. Because these tinfoil capsules but are very expensive, there has been a move to manufacture bottle caps from aluminum. Although these capsules are considerably cheaper than the tinfoil capsules, they can be because of the Brittleness of the metal without forming folds, difficult to apply to the neck of the bottle.

Man hat daher auch bereits Flaschenkapseln aus Kunststoff hergestellt. Hierbei wurde als Material in erster Linie Polyvinylchlorid verwendet, welches aufgeweitet wurde und dann durch Aufschrumpfen unter Wärmeeinwirkung auf den Flaschenhals aufgebracht werden konnte. Diese bekannten Schrumpfkapseln wurden durch Tauchen aus einem Weichmacher enthaltenden Polyvinylchlorid in der gewünschten Form hergestellt. Ein Nachteil dieser Schrumpfkapseln besteht darin, daß das Aufbringen auf den Flaschenhals, infolge des weichen Materials des Deckels Schwierigkeiten bereitet und den Verschlußvorgang, insbesondere im Anschluß an Füll- und Verschlußmaschinen dadurch erschwerte, daß die mit den Kapseln versehenen Flaschen mit ihrem Hals in heißes Wasser getaucht werden mußten. Der Arbeitsaufwand war dadurch recht erheblich.Bottle caps have therefore already been made from plastic. The material in primarily polyvinyl chloride used, which was expanded and then shrunk under Heat could be applied to the neck of the bottle. These well-known shrink capsules were made by dipping from a plasticizer-containing polyvinyl chloride in the desired shape manufactured. A disadvantage of these shrink capsules is that the application to the bottle neck, as a result of the soft material of the lid causes difficulties and the locking process, in particular in connection with filling and sealing machines made difficult by the fact that the capsules provided Bottles had to be dipped in hot water with their necks. The workload was thereby quite considerable.

Der Erfindung liegt die Aufgabe zugrunde ein Verfahren zum Herstellen von Schrumpfkapseln zuThe invention is based on the object of a method for producing shrink capsules

ίο schaffen, welches auf unkomplizierte und wirtschaftliche Weise Flaschenkapseln liefert, die sich ohne Schwierigkeiten auf einen Raschenhals aufbringen lassen und faltenlos den Flaschenhals umschließen.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zunächst aus einer Platte oder einem Band aus starrem Material eine kreisrunde Scheibe ausgestanzt, diese durch Umbördeln eines Randes zu einer Kappe geformt und anschließend an dem Rand der Kappe eine Hülse aus unter Wärmeeinwirkung schrumpfbarem Kunststoff, beispielsweise Polyvinylchlorid, befestigt wird.ίο, which delivers bottle caps in an uncomplicated and economical way, which can be attached to a quick neck without any difficulties and which surround the bottle neck without creases.
According to the invention, this object is achieved in that a circular disk is first punched out of a plate or a band of rigid material, this is formed into a cap by flanging an edge and then a sleeve made of plastic that can be shrinked under the action of heat, for example polyvinyl chloride, is attached to the edge of the cap. is attached.

Das Verfahren gemäß der Erfindung läßt sich auch leicht für Massenherstellung auf einer entsprechen- Γ den Maschine anwenden. Hierbei wird zweckmäßig die aus einer Platte oder besser einem Band aus Metall oder nichtschrumpfbarem Kunststoff ausgestanzte kreisrunde Scheibe vor die Stirnseite eines Domes geführt, dort durch Umbördeln zu, einer Kappe geformt und dann aus Abschnitten eines fortlaufenden Bandes aus schrumpfbarem Kunststoff die Hülse durch Befestigen am Kappenrand gebildet. Der Dorn besitzt zweckmäßig unterhalb der Höhe des Kappenrandes eine Rille, in welche dann das Material der Hülse eingeschrumpft wird. Die freien Enden der aus dem Band gewonnenen Abschnitte werden vorteilhaft durch Verkleben oder Verschweißen miteinander verbunden. Die Verbindung von Hülse und Kappenrand kann auf einfache Weise durch stellenweises Aufschrumpfen mittels Wärmezufuhr vorge-The method of the invention can also be easy for mass production on a corresponding Γ apply the machine. In this case, the circular disc punched out of a plate or, better, a band made of metal or non-shrinkable plastic is guided in front of the end face of a dome, formed into a cap there by flanging and then the sleeve is made from sections of a continuous band of shrinkable plastic by fastening it to the edge of the cap educated. The mandrel expediently has a groove below the level of the cap edge, into which the material of the sleeve is then shrunk. The free ends of the sections obtained from the tape are advantageously connected to one another by gluing or welding. The connection between the sleeve and the edge of the cap can be prepared in a simple manner by shrinking them on in places with the aid of a heat supply.

Um die meist erforderliche konische Form der Hülse der Schrumpf kapsel zu erhalten, werden in an sich bekannter Weise die Abschnitte vor dem Aufwickeln trapezförmig geschnitten. Das Band ausIn order to obtain the conical shape of the sleeve of the shrink capsule, which is usually required, in an known way, the sections cut trapezoidal before winding. The tape off

schrumpf barem Kunststoff kann auch so bemessen ^ werden, daß die gebildete Hülse über den Deckel der Kappe übersteht und dann über diesen umgelegt wird.shrinkable plastic can also be dimensioned so that the sleeve formed over the lid of the The cap protrudes and is then folded over it.

Da die Kappe der Schrumpfkapsel der Erfindung aus starrem Material hergestellt ist, bleibt diese auch nach dem Aufbringen der Schrumpfkapsel auf die Flasche in ihrer Form völlig glatt und faltenlos erhalten. Dieser Deckel der Schrumpfkapsel kann noch auf dem Dom mit einer Prägung oder einem Aufdruck versehen werden.Since the cap of the shrink capsule of the invention is made of rigid material, it remains after the shrink capsule has been applied to the bottle, its shape is completely smooth and wrinkle-free. This cover of the shrink capsule can also be embossed or printed on the dome be provided.

Sowohl das Material der Kappe wie das schrumpfbare Material der Hülse kann vor der Herstellung in der gewünschten Farbgebung auf Rollen aufgewickelt und von dort der Maschine zugeführt werden.Both the material of the cap and the shrinkable material of the sleeve can be in the desired color can be wound up on rolls and fed from there to the machine.

Nach dem Verschließen der Flaschen und dem Aufbringen der Schrumpfkapseln können die Flaschen auf einfache Weise auf einem Transportband durch einen Tunnel geführt werden, in welchem der Schrumpfvorgang durch Wärmezufuhr an dem oberen Teil der Flaschen bewirkt wird.After closing the bottles and applying the shrink capsules, the bottles can be easily guided on a conveyor belt through a tunnel in which the Shrinking process is caused by the supply of heat to the upper part of the bottles.

Mit dem Verfahren gemäß der Erfindung ist es auch möglich, Schulterkapseln wie sie aus Metall bekannt sind, herzustellen.With the method according to the invention it is also possible to produce shoulder capsules such as those known from metal are to produce.
