Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Verschließen von Flaschen und dergleichen Behältern aus thermoplastischem Kunststoff.The invention relates to a method and a device for closing bottles and the like Thermoplastic containers.

Im Zuge der Entwicklung der Kunststoffverarbeitung sind auch Flaschen und dergleichen Behälter aus Kunststoff bekanntgeworden, die zum Aufbewahren und Versenden flüssiger oder pulvriger Stoffe dienen. Sie besitzen meistens einen Flaschenhals mit Gewinde, auf welchem eine aus gleichem oder anderem Werkstoff bestehende Verschlußkapsel aufgeschraubt wird. Diese Verschlußart ist ziemlich umständlich herzustellen und bedingt auch eine besondere Lagerhaltung von Flaschen, Kapsem und eventuellen Dichtungsscheiben. Auch ist es so möglich, daß Flaschen mit Substanzen nachgefüllt werden, die nicht dem Etikettaufdruck entsprechen. Dadurch entsteht eine erhöhte Unfallgefahr. Weiterhin ist es bekannt, flüssige und pulvrige Stoffe in Schläuchen, Beuteln und ähnlichen Behältern aus Kunststoff aufzubewahren, die mittels Heißsiegeln (Impulsverfahren) verschlossen werden. Der Nachteil dieser Verschlußmethode besteht darin, daß die Heißsiegelstelle selbst infolge veränderter Oberflächenstruktur eine höhere Wasserdampfdurchlässigkeit aufweist als die nicht behandelten Stellen und nur bei dünnen Wandstärken anwendbar ist.In the course of the development of plastics processing, bottles and the like are also containers Made of plastic, which is used to store and send liquid or powdery substances to serve. They usually have a threaded bottle neck on which one of the same or another Material existing cap is screwed on. This type of closure is quite cumbersome produce and also requires a special storage of bottles, capsules and any sealing washers. It is also possible that bottles are refilled with substances, which do not correspond to the label. This creates an increased risk of accidents. Furthermore it is known to store liquid and powdery substances in hoses, bags and similar containers made of plastic, which are closed by means of heat sealing (impulse method). The disadvantage of this locking method consists in the fact that the heat sealing point itself as a result of the changed surface structure has a higher Has water vapor permeability than the untreated areas and only with thin wall thicknesses is applicable.

Schließlich ist es bekannt, zwei Kunststoffteile derart miteinander zu verbinden, daß zwischen diese eine Zeitlang ein heißer Metallkörper gedrückt wird, bis die einander zugekehrten, mit dem Metallkörper in Berührung gebrachten Kunststoffflächen zu schmelzen beginnen und der Metallkörper zu gleiten beginnt. Er wird dann entfernt und die beiden Kunststoffteile aneinandergepreßt. Diese Methode ist insofern nachteilig, als Kunststoffteile an der geheizten Fläche hängenbleiben können und herausgerissen werden. Bei Anwendung des Verfahrens zum Verschließen von Flaschen aus thermoplastischen Kunststoffen würden undichte Schweißstellen entstehen. Außerdem ist ein derartiges Verfahren schon wegen der erforderlichen häufigen Reinigung der Heizfläche für automatische Verschlußmaschinen unbrauchbar.Finally, it is known to connect two plastic parts to one another in such a way that one between them A hot metal body is pressed for a while until the two facing each other come into contact with the metal body The plastic surfaces that have been brought into place begin to melt and the metal body begins to slide. He is then removed and the two plastic parts pressed together. This method is disadvantageous in that plastic parts are attached to the heated surface can get caught and torn out. When using the method of closing Thermoplastic bottles would result in leaky welds. aside from that is such a method because of the required frequent cleaning of the heating surface for automatic Sealing machines unusable.

Durch die Erfindung werden diese Nachteile dadurch vermieden, daß gegen die Innenwand des Flaschen- bzw. Behälterhalses aus thermoplastischem Kunststoff allseitig Heißluft geblasen und der Hals, nachdem die Innenwand bis zum Schmelzpunkt erhitzt ist, von außen fest zusammengedrückt wird.By the invention, these disadvantages are avoided in that against the inner wall of the Bottle or container neck made of thermoplastic material blown hot air on all sides and the neck, after the inner wall is heated to the melting point, is firmly pressed together from the outside.

Auf diese Weise entsteht ein Flaschenverschluß, der als Originalverschluß gilt. Die beiden gegenüberliegenden Innenwandteile des Flaschenhalses werden fest und dicht miteinander verschweißt, ohne die Verfahren und Vorrichtung zum Verschließen von Flaschen und dergleichen BehälternIn this way, a bottle cap is created that is considered an original cap. The two opposite Inner wall parts of the bottle neck are firmly and tightly welded together without the Method and device for closing bottles and similar containers

Struktur des Kunststoffes in der ganzen Tiefe der Wandstärke zu verändern.
An Hand der Zeichnung sei das Verfahren und die zur Durchführung des Verfahrens möglichen Vorrichtungen beispielsweise näher erläutert.To change the structure of the plastic in the entire depth of the wall thickness.
The method and the devices possible for carrying out the method are explained in more detail, for example, with reference to the drawing.

Die zu verschließende Flasche 1 wird in einem Gestell — hier nicht mitdargestellt — gehalten. Oberhalb des Haschenhalses 2 ist ein Kolben 3 beweglich so angeordnet, daß er in den Flaschenhals 2 (Fig. 1 und 2) hineingetaucht werden kann, ohne die Innenwand des Flaschenhalses zu berühren. Der Kolben ist hohl, mit Löchern 6 versehen und über ein Rohr 5 mit einer Vorrichtung zur dauernden oder zeitweiligen Zufuhr heißer Luft oder heißen Gases (Schutzgas) verbunden.The bottle 1 to be closed is held in a frame - not shown here. Above the neck of the hook 2, a piston 3 is movably arranged so that it is in the bottle neck 2 (Fig. 1 and 2) can be immersed without touching the inside wall of the bottle neck. The piston is hollow, provided with holes 6 and via a tube 5 with a device for permanent or temporary Supply of hot air or hot gas (protective gas) connected.

Sobald der Kolben 3 in den Flaschenhals 2 eingetaucht ist, werden durch die Löcher 6 allseitig heiße Gase oder Luft gegen die Innenwand des Flaschenhalses geblasen, wodurch diese zum Schmelzen gebracht wird. Sobald der Schmelzpunkt erreicht ist, wird der Kolben aus dem Flaschenhals herausgezogen. Außerhalb des Flaschenhalses ist ein bewegliches Preßbackenpaar 4 so angeordnet, daß der Flaschenhals nach dem Entfernen des Kolbens 3 zusammengepreßt werden kann (Fig. 3).As soon as the piston 3 is immersed in the bottle neck 2, the holes 6 become hot on all sides Gas or air is blown against the inside wall of the bottle neck, causing it to melt will. As soon as the melting point is reached, the plunger is withdrawn from the neck of the bottle. Outside the bottle neck a movable pair of jaws 4 is arranged so that the Bottle neck can be compressed after removing the piston 3 (Fig. 3).

Es ist sehr vorteilhaft, diese Querschnittsform des Kolbens ähnlich dem Querschnitt des Flaschenhalses auszuführen.It is very advantageous to have this cross-sectional shape of the piston similar to the cross-section of the bottle neck to execute.

Zur Kennzeichnung des Verschlusses ist es in zweckmäßiger Ausgestaltung der Erfindung möglich, die Preßbacken mit einer entsprechenden Gravur zu versehen.To identify the closure, it is possible in an expedient embodiment of the invention, to provide the press jaws with a corresponding engraving.

Die erfindungsgemäße Verschlußart eignet sich insbesondere beim Verschluß von Flaschen mit ätzenden oder sonstwie schädlichen Chemikalien, für die die Flaschen nur einmal verwendet werden dürfen.The type of closure according to the invention is particularly suitable for the closure of bottles with corrosive or other harmful chemicals for which the bottles can only be used once.
