Verfahren zum Herstellen tor Schrumpfkapseln und nach dem Verfahren hergestellte SchrumpfkapselProcess for producing tor shrink capsules and according to the Process manufactured shrink capsule

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen von Sehrumpf kapseln,, die dazu "bestimmt sind, bereits mit Stöpsel, insbesondere Korken., verschlossene !laschen zu umschliessen, ferner umfasst die Erfindung eine nach.diesem Verfahren hergestellte Schrumpf kapsel. .....The invention relates to a method of manufacture from very hull capsules "which are intended" already with Stoppers, especially corks, to enclose closed flaps, The invention further comprises one according to this Process manufactured shrink capsule. .....

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 eingef ührt ist*It is already known the estuary and the. upper part of the Necks of bottles, especially for wine or spirits or to capsulate cosmetics after the stopper or cork is introduced *

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 Staniolkaps-eln aber -sehr kostspielig sind^ ist man dazu Ub er gegangen ^ Fl^scihenkapseln aus. .Aluminium ke.*·- zustellen% Diese Kapseln sind zwar erheblieji balliger als die Stanie·!kapseln* lass.en sich Jedoch wegen der Sprödigkeit des Metalles, ohne Falten zu bilden, schwer auf den Flaschenhals auf br ing en· % Various types of capsules are known for this purpose. »Capsules made of tin foil have proven to be ideal because they can be attached to the neck of the bottle without creases. Since these tin capsules are very expensive, however, one went over to them ^ bottle capsules. .Aluminium ke. * · - deliver % These capsules are considerably more convex than the Stanie ·! Capsules * can, however, because of the brittleness of the metal, be attached to the bottle neck with difficulty without forming folds %

Man hat daher auch bereits Flasohenkapseln aus Kunststoff hergestellt. Hierbei wurde als Material in erstem 3j.ija.ie PoIy-vinylehlorld verwendet, welches aufgeweitet wurde und dann durch aufschrumpfen unter Wärmeeinwirkung auf den Flaschen-Flasher capsules have therefore already been made from plastic. The material used in the first 3j.ija.ie was PoIy-vinylehlorld used, which was widened and then shrunk on the bottle under the action of heat.

hals auf gebracht werden konnte. Diese bekannten Schrunipfkapseln wurden durch Tauchen aus einem Weichmacher enthaltenden Polyvinylchlorid in der gewünschten Form hergestellt. Sin Nachteil dieser Sehrumpfkapseln 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 Versehlußmaschinen dadurch erschwerte, daß die "mit den Kapseln versehenen Flaschen mit ihrem Hals in heißesWasser getaucht werden mußten. Der Arbeitsaufwand war dadurch recht erheblich.throat could be brought up. These well-known shrink capsules were made by dipping from a plasticizer containing Polyvinyl chloride produced in the desired shape. A disadvantage of these very hull capsules is that that the application, on the bottle neck, as a result of the soft Material of the lid ^ causes difficulties and the locking process, especially in connection with filling and sealing machines made more difficult by the fact that the "with the capsules with their necks dipped in hot water had to be. The workload was therefore quite considerable.

Der Erfindung liegt die Aufgabe zugrunde ein Verfahren zum Herstellen von Schrumpf kapseln zu schaffen,, welches auf unkomplizierte und wirtsohaftliehe Weise Flaschenkapseln liefert, die sich ohne Schwierigkeiten auf einen Flaschenhals aufbringen lassen und faltenlos den Flaschenhals umschliesseu.The invention is based on the object of a method for Manufacture of shrink capsules to create, which is uncomplicated and delivers bottle caps in an economical manner, which can easily get on the neck of a bottle leave and wrap around the neck of the bottle without wrinkles.

Diese Aufgabe wi?d erfindungsgemäß, dadurch gelöst, daß zunächst aus einer Hatte oder einem Band aus starrem Material eine kreisrunde Sßhtibe ausgestanzt, diese durch ümbördeln eines Halides zu einer Kappe geformt wird und anschließend an dem land der Kappe, eine Hülse aus unter Wäremeeinwirkung schrumpfbar em ijuhgtstof^* beispielsweise Polyvinylchlorid, gefestigt wird*According to the invention, this object is achieved by initially made of a hat or a band of rigid material a circular shaft is punched out, this by flanging of a halide is formed into a cap and then on the land of the cap, a sleeve made of heat shrinkable em ijuhgtstof ^ * for example polyvinyl chloride, is consolidated *

Das Verfahren gemäß der Irfxndung lässt sich auch leicht für Massenhersteilung, auf einer entsprechenden Maschine anwenden, Hierbei wird zweckmäßig die· aus einer Platte oder besser einem. Band aus Metall oder nichtschrumpfbarem Kunst-* stoff ausgestanzte kreisrunde. Scheibe vor die Stirnseite eines Dornes geführt» dort durch Ümbördeln zu einer Kappe geformt und dann aus Abschnitten eines fortlaufenden Bandes aus schrumpfbarem Kunststoff die Hülse durch BefestigenThe method according to the invention can also be easily carried out for mass production, use on a corresponding machine, In this case, the · from a plate or better one. Band made of metal or non-shrinkable plastic * fabric punched out circular. Disc in front of the front a thorn led »there by crimping to a cap shaped and then made from sections of a continuous ribbon the sleeve made of shrinkable plastic by fastening it

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 vorgenommen werden.formed on the cap edge. The mandrel expediently has a groove below the level of the cap edge, in which then the material of the sleeve is shrunk. The free ends of the sections obtained from the tape become advantageous connected to one another by gluing or welding. The connection between the sleeve and the cap edge can be easily achieved by shrinking them in places using the supply of heat be made.

Um die meist erforderliche konische Form der Hülse der S chrumpf kaps el zu erhalten, werden in an sich bekannter Y/eise die Abschnitte vor dem Aufwickeln trapezförmig geschnitten. Das Band aus schrumpfbarem Kunststoff kann auch so bemessen werd®} daß die gebildete Hülse über den Deckel der Kappe übersteht und dann über diesen umgelegt wird.To get the most necessary conical shape of the sleeve Shrink capsules are obtained in a manner known per se cut the sections trapezoidal before winding. The shrinkable plastic tape can also be sized werd®} that the sleeve formed over the lid of the cap survives and is then thrown over this.

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 Schrumffkapsel kann noch auf dem Dorn mit einer Prägung oder einem Aufdruck versehen werden.Since the cap of the shrink capsule of the invention is made of rigid Material is made, this remains completely in its shape even after the shrink capsule has been applied to the bottle received smooth and wrinkle-free. This cover of the shrink capsule can still be embossed or embossed on the mandrel Imprint.

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 HUgeführt werden.Both the material of the cap and the "shrinkable material" the core can be wound onto rolls in the desired color before production and transferred to the machine from there HU are carried out.

Nach dem Verschließen der Flaschen und dem Aufbringen der Schrumpfkapsein 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 wirdt After sealing the bottles and applying the Schrumpfkapsein the bottles can be easily performed on a conveyor belt through a tunnel, in which the shrinking process effected by supplying heat to the upper portion of the bottles t
