Description

Kronverschluß. Crown lock.

Die Erfindung bezieht sich auf einen Kronverschluß aus vorsugsweise thermoplastischen Kunststoffen, beispielsweise Phenol-, Harnstoff-, Melaminharzpressmassen bzw. Polyäthylen, Polypropylen, Polyvinylchlorid od. dgl.The invention relates to a crown lock from preventive thermoplastic plastics, for example phenolic, urea, melamine resin molding compounds or polyethylene, polypropylene, polyvinyl chloride or the like.

Pur die Herstellung von Forzkdrpern aus duro- und thermoplastischen Kunststoffen kennt man verschiedene Methoden. Beispielsweise ist es bei thermoplastischen Kunststoffen bekannt, Pormkörper im Spritzgußverfahren herzustellen. Ebenso ist es bekannt, Formkörper im Preßverfahren und insbesondere im Kaltfließpreßverfahren analog der Verarbeitung von Metallen herzustellen.Pur the production of molded parts from thermosetting and thermoplastic Different methods are known to plastics. For example, it is thermoplastic Plastics known to produce Pormkörper by injection molding. Likewise is it is known, molded bodies in the compression process and in particular in the cold extrusion process analogous to the processing of metals.

Aufgabe der Erfindung ist es, einen gut dichtenden Kronverschluß aus thermoplastischem Kunststoff zu schaffen, der in kontinuierlicher Arbeitsweise hergestellt werden kann.The object of the invention is to provide a well-sealing crown closure to create thermoplastic material that is manufactured in a continuous manner can be.

Der erfindungsgemäße Kronverschluß ist dadurch gekennzeichnet, daß er einen im Durchmesser mit Untermaß ausgebildeten und mit Rippen versehenen Rand aufweist und aus einem bei kurzzeitiger mechanischer Reckung sich zumindest annähernd in seine Ursprungsform zurUckbildenden Material hergestellt ist.The crown closure according to the invention is characterized in that it has an edge that is undersized in diameter and provided with ribs has and from a short-term mechanical stretching at least approximately is produced in its original form restoring material.

Auf diese Weise wird von der elastischen Eigenschaft des Materials in der Weise Gebrauch gemacht, daß der Rand des Kronenverschlusses in bezug auf die Plaschen mit Untermaß ausgebildet und mit Rippen versehen wird, so daß eine kurzfristige mechanische Reckung sich zumindest nahezu völlig wieder zurllckbildet. Dabei kann vorgesehen sein, den Kronverschluß mit einer DichtungseinLage zu versehen, die sowohl einstückig angeformt oder auch als gesondertes Teil aÅge£ertigt und eingelegt werden kann.This way it takes advantage of the elastic property of the material made use of that in relation to the edge of the crown lock the Plaschen is formed with undersize and provided with ribs, so that a short-term mechanical stretching at least almost completely disappears again. It can be provided that the crown closure is provided with a sealing insert, which are either molded in one piece or manufactured and inserted as a separate part can be.

Zur leichteren Handhabung beim Verschließen der Flaschen auf der Abfüllanlage kann das Material des Kronenverschlusses mit magnetisierbarem Metall, vorzugsweise in Form von Staub, versetzt werden.For easier handling when closing the bottles on the filling line The material of the crown clasp can be made of magnetizable metal, preferably in the form of dust.

Nach einem weiteren Erfindungsgedanken ist der Kronenverschluß an seiner Innenseite mit einer in den Hals der zu verschließenden Flasche hineinragender Dichtungslippe versehen.According to a further idea of the invention, the crown lock is on its inside with a protruding into the neck of the bottle to be closed Provide sealing lip.

Beim Aufdrücken des Kronverschlusses auf den Flaschenhals tritt nur eine geringfügige kurzzeitige Dehnung pro Rippe auf und durch die zweite, innen angebrachte konische Lippendichtung wird die Flasche dicht verschlossen.When pressing the crown cap on the bottle neck only occurs a slight short-term stretch per rib on and through the second, inside attached conical lip seal, the bottle is tightly closed.

Die Erfindung ist in der Zeichnung in einem Busführungsbeispiel gezeigt und wird anhand dieses im folgenden noch erläutert.The invention is shown in the drawing in an example of a bus routing and is explained on the basis of this in the following.

In der Zeichnung ist der erfindungsgemäße Kronenkorken 18 in dem dreiteiligen Werkzeugstempel dargestellt, in dem er ausgebildet wird.In the drawing, the crown cap 18 according to the invention is in the three-part Tool stamp shown in which it is trained.

Wie in der linken Hälfte der Figur gezeigt, dienen die Teile 19a und 19b in Verbindung mit dem Formnest 2 zur Ausbildung des mittleren Teils des Bodens und der rippenartigen Ringdichtung 18a und die Teile 19b und 19c wiederum in Verbindung mit dem Formnest 2 zur Bildung des äußeren Teils des Bodens und des äußeren Randes 18b. Dabei ist die Teilung des Stempels in die Teile 19b und 19c insbesondere deshalb vorgenommen, um nach dem Fertigpressen und hinreichenden Abktllilen bzw. im Falle von Duroplasten einer genügenden Aushärtung des Formlings zunächst den sich noch auf dem Stempel befindlichen Formling aus dem Forinnest ausfahren zu können und alsdann nach Zurückfffhren der FUhrungshlllse 15 durch Vorschieben des Teils 19c den Kronenverachluß unter vorübergehendem Recken seines Randes 18b über das gewölbte Ende 19d des Stempelteils 19b zu schieben.As shown in the left half of the figure, parts 19a and 19a serve 19b in connection with the mold cavity 2 to form the central part of the bottom and the rib-like ring seal 18a and the parts 19b and 19c in turn in connection with the mold cavity 2 to form the outer part of the bottom and the outer edge 18b. The division of the stamp into parts 19b and 19c is particularly important for this reason made to after the final pressing and sufficient Abktllilen or in the case of thermosets, sufficient curing of the molded part is still possible to be able to pull out the molding located on the stamp from the forinnest and then after returning the guide sleeve 15 by advancing the part 19c the crown closure with temporary stretching of its edge 18b over the arched To push the end 19d of the stamp part 19b.
