Description

Die Erfindung bezieht sich auf Verfahren und Vorrichtungen zum Verschließen von Kunststoffflaschen mit flachen Scheiben, die aus einem aus schweißbarem Kunststoff bestehenden oder aus einem mit einem solchen Werkstoff beschichteten Band entnommen, auf den Mündungsrand der Flasche aufgelegt und unter Anwendung von Druck und Wärme mit diesem fest und dicht verbunden werden. Diese Art des Verschließens von Flaschen gewährleistet gegenüber den üblichen Verschlußmitteln, wie Kork- oder Kunststoffstopfen, Schraubkappen u. dgl, nicht nur einen völlig gasdichten Abschluß des Flascheninhalts gegenüber der Außenluft, sondern ergibt auch einen gegenüber Innendruck zuverlässig dichten Verschluß. Dies ist von besonderer Bedeutung bei Kunststoffflaschen, insbesondere, wenn diese dünnwandig sind, da derartige Flaschen durch auf Teile ihrer Wand wirkenden äußeren Druck, wie er auf dem Transport, beim Lagern oder Hantieren leicht auftritt, verformt und dabei in ihrem Volumen verkleinert werden. Ein Flaschenverschluß durch mit dem Mündungsrand dicht und fest verbundene, insbesondere verschweißte Scheiben erfordert im übrigen einen außerordentlich geringen Aufwand an Verschlußmaterial und hat infolgedessen auch extrem geringes Gewicht und ist auch preiswert herzustellen.The invention relates to methods and apparatus for closing plastic bottles with flat washers, which are made from a weldable Existing plastic or taken from a strip coated with such a material, placed on the mouth edge of the bottle and with the application of pressure and heat with this be firmly and tightly connected. This type of closure of bottles guarantees against the usual closure means, such as cork or plastic stoppers, screw caps and the like, not just one completely Gas-tight seal of the bottle contents against the outside air, but also results in an opposite Internal pressure reliably tight closure. This is of particular importance for plastic bottles, especially if these are thin-walled, since such bottles act on parts of their wall external pressure, as it easily occurs during transport, storage or handling, is deformed and are thereby reduced in their volume. A bottle cap through with the mouth rim tightly and firmly connected, in particular welded panes requires an extraordinary low cost of closure material and as a result has and is extremely low weight also inexpensive to manufacture.

Bei bekannten Verfahren der eingangs erwähnten Art erfolgen das Herstellen der durch Anwendung von Druck und Wärme mit dem Rand der Behälteröffnung verkleb- oder verschweißbaren Scheiben, das Auflegen dieser Scheiben auf den Behälterrand sowie das Andrücken und Erwärmen der Scheibe getrennt nacheinander, und zwar auch dann, wenn — wie gleichfalls bekannt — das Ausstanzen der Scheiben aus einem längsbewegten Band, das Auflegen der ausgestanzten Scheibe auf den Behälterrand und ihr Andrücken und Erwärmen in ein und derselben Vorrichtung geschieht. Das bedeutet, daß sowohl — falls vorhanden — das Band, die Scheiben und die zu verschließenden Behälter nacheinander mehrere Stationen der Vorrichtung durchlaufen müssen, wodurch das Verfahren reichlich umständlich und die Vorrichtung entsprechend kompliziert und aufwendig wird.In known methods of the type mentioned at the outset, the manufacture is carried out by using Pressure and heat with the edge of the container opening can be glued or welded panes, the placement these discs on the edge of the container as well as pressing and heating the disc separately one after the other, even if - as is also known - the punching out of the disks a longitudinally moving belt, placing the punched disc on the edge of the container and pressing it and heating occurs in one and the same device. This means that both - if available - the tape, the panes and the containers to be closed one after the other several stations the device must go through, which makes the procedure cumbersome and cumbersome the device becomes correspondingly complicated and time-consuming.

Zweck der Erfindung ist die Schaffung eines Verfahrens und der für seine Durchführung geeigneten Mittel, die auf denkbar einfache Weise und mit geringstem materiellen und vorrichtungsmäßigen Aufwand die Gewinnung der Scheiben aus einem Band sowie ihr Auflegen und Verbinden mit dem Behälter durch Anwendung von Druck und Wärme gestatten.The purpose of the invention is to create a method and the means suitable for its implementation, which in the simplest possible way and with the least material and equipment expenditure, the extraction of the disks from a tape and allow them to be placed on and connected to the container by the application of pressure and heat.

schließen von Kunststoffflaschen mit aus einem aus schweißbarem Kunststoff bestehenden oder mit einem solchen Kunststoff beschichteten Band zu entnehmenden Scheiben erfindungsgemäß dadurch, daß das absatzweise geförderte Band mit jeweils einer Scheibe über der Mündung einer Flasche zentriert wird, die noch mit dem Band verbundene Scheibe mit der Flaschenmündung verschweißt und anschließend das Band unter Ablösen der mit der Flaschenmündung verschweißten Scheibe von dieser abgezogen wird.close plastic bottles with or with a made of weldable plastic such plastic-coated tape to be removed disks according to the invention in that the intermittent The conveyed belt is centered over the mouth of a bottle with one disc each The disc still connected to the tape is welded to the bottle mouth and then the Tape is pulled off from the bottle mouth while detaching the disc welded to it.

Dadurch, daß das die Scheibe noch enthaltende Band, auf der Flaschenmündung aufliegend, mit dieser gemeinsam unter die Schweißstelle geführt und nach dem Verschweißen von der Schweißstelle wegbewegt wird, wobei der Bandrest von der auf der Flasche verbleibenden Scheibe getrennt wird, ergibt sich eine kontinuierliche Arbeitsweise, die mit Hilfe einer äußerst einfachen, schnell arbeitenden und nur geringen Aufwand erfordernden Vorrichtung durchzuführen ist. Um den Aufwand an wertvollem thermoplastischem Kunststoff zu verringern, andererseits gleichwohl einen nicht nur dichten, sondern auch besonders druckfesten Flaschenverschluß zu erzielen, kann das Band aus einem wärmebeständigen Werkstoff, z. B. Zellhaut, Zelluloseazetat, aber auch aus Papier, Metall od. dgl. bestehen, der auf der der Flaschenöffnung zugewandten Seite mit einem thermoplastischen Kunststoff beschichtet ist.The fact that the tape still containing the disc rests on the bottle mouth with this guided together under the welding point and moved away from the welding point after welding is, with the remainder of the tape being separated from the disc remaining on the bottle, the result is a continuous way of working, which with the help of an extremely simple, fast working and only minor Expenditure requiring device is to be carried out. To the expense of valuable thermoplastic To reduce plastic, on the other hand not only seal one, but also special To achieve pressure-resistant bottle closure, the tape can be made of a heat-resistant material such. B. Cell skin, cellulose acetate, but also made of paper, metal or the like. Consist of the one facing the bottle opening Side is coated with a thermoplastic plastic.

Zur Erleichterung der Trennung von Scheibe und Bandrest kann ein Band Verwendung finden, das im Verlauf der Scheibenumfänge Perforationslinien auf-To facilitate the separation of the disc and the remainder of the tape, a tape can be used which is in the Perforation lines on the circumference of the pane

To move the belt with the help of easier Toothed guide rollers can this tape on one or both edges - similar to a movie - be provided with edge perforations.

Eine geeignete Vorrichtung zur Durchführung des vorgenannten Verfahrens ergibt sich, wenn nahe vor und hinter dem Schweißstempel je eine mit in die Randperforation des Bandes eingreifenden Zähnen versehene Umlenkrolle für das die Scheiben enthaltende Band vorgesehen ist, von denen die dem Schweißstempel nachgeschaltete Rolle federnd auf dem Flaschenhals aufliegt und das Band unter Lösen von der auf der Flasche verbleibenden Scheibe nach oben umlenkt. Die letztgenannte Umlenkrolle ist vorzugsweise hohl und von Kühlluft durchströmt, damit in jedem Fall die Schweißnaht ausreichend gekühlt und verfestigt ist, bevor der Bandrest abgezogen wird.A suitable device for carrying out the aforementioned method is obtained when near before and behind the welding die, one each with teeth engaging in the edge perforation of the strip provided pulley is provided for the tape containing the discs, of which the Welding stamp downstream roller rests resiliently on the bottle neck and loosens the tape deflects upwards from the disc that remains on the bottle. The latter pulley is preferred hollow and flowed through by cooling air, so that the weld seam is adequately cooled in every case and is solidified before the remainder of the tape is peeled off.
