Description

Die Erfindung betrifft eine Schraubverschlußanordnung mit Originalitätssicherung für Behälter, insbesondere Flaschen.The invention relates to a screw cap arrangement with tamper-evident device for containers, in particular bottles.

Es gibt bereits eine Reihe von Schraubverschlußanordnungen mit Originalitätssicherung für Behälter aller Art, z.B. Glas oder Plastikflaschen, die so konstruiert sind, daß ersichtlich ist, ob der Behälter bereits geöffnet wurde. In der Regel wird dies dadurch erreicht, daß beim ersten vollständigen oder auch nur teilweisen Öffnen Teile des Verschlusses abreißen und auf diese Weise eine Manipulation am Verschluß erkennbar wird.There are already a number of screw cap arrangements with tamper evident for containers of all kinds, e.g. Glass or plastic bottles that are designed to show whether the container has already been opened. As a rule, this is achieved by tearing off parts of the closure the first time it is opened completely or only partially, and in this way tampering with the closure becomes recognizable.

Diese bekannten Verschlußsysteme haben jedoch Nachteile, die die ordnungsgemäße Funktion in Frage stellen. In vielen Fällen läßt sich die Sicherung mit einfachen Mitteln so manipulieren, daß ein Öffnen auch ohne Zerstörung der Originalitätssicherung möglich ist. Oft sind die Soll-Bruchstellen so schwach ausgelegt, daß es schon bei der Verarbeitung oder beim Transport zur Zerstörung der Originalitätssicherung kommt. Sind die Soll-Bruchstellen dagegen verstärkt, ist der zum Öffnen des Verschlusses notwendige Kraftaufwand zu hoch, so daß der Behälter nur schwer geöffnet werden kann. Schließlich ist auch bei vielen bekannten Verschlüssen eine Verarbeitung in automatisch arbeitenden Anlagen nicht möglich.However, these known closure systems have disadvantages which jeopardize their proper functioning. In many cases the security can be manipulated with simple means so that it can be opened without destroying the tamper-evident device. Often, the predetermined breaking points are so weak that the tamper-evident device is destroyed during processing or transport. If, on the other hand, the predetermined breaking points are reinforced, the force required to open the closure is too high, so that the container can only be opened with difficulty. Finally, even with many known closures, processing in automatic systems is not possible.

Es bestand daher die Aufgabe, eine Verschlußanordnung zu finden, die die genannten Nachteile vermeidet und insbesondere einen verbesserten Schutz gegen unbefugtes Öffnen und gegen ungewollte Beschädigungen bei Verarbeitung und Transport bietet, die trotzdem ohne großen Kraftaufwand geöffnet werden kann und die auch auf automatisch arbeitenden Verschließmaschinen als Einheit verarbeitet werden kann.The object was therefore to find a closure arrangement which avoids the disadvantages mentioned and in particular offers improved protection against unauthorized opening and against unwanted damage during processing and transport, which can nevertheless be opened without great effort and which can also be used on automatically operating sealing machines Unit can be processed.

Diese Aufgabe wurde durch die vorliegende Erfindung ge-löst.This object has been dissolved by the present invention e-g.

Gegenstand der Erfindung ist demgemäß eine Schraubverschlußancrdnung mit Originalitätssicherung für Behälter, insbesondere Flaschen, mit einer auf den Behälter aufschraubbaren Schraubkappe, Abreißsegmenten, die beim ersten Öffnen des Verschlusses abreißen, mit gegen die Schließrichtung weisenden Federlaschen, unterhalb des Schraubgewindes am Behälterhals angebrachten, in Schließrichtung weisenden sägezahnartigen Nocken und einem nach außen weisenden Wulstrand am unteren Teil der Schraubkappe, dadurch gekennzeichnet, daß die Abreißsegmente und ihre Anbindungen

  • a) innerhalb der Schraubkappe liegen,
  • b) von dem Wulstrand der Schraubkappe vollständig abgedeckt werden und
  • c) eine mit der Schraubkappe gemeinsam verarbeitbare Einheit bilden.
The invention accordingly relates to a screw cap with tamper-evident device for containers, in particular bottles, with a screw cap that can be screwed onto the container, tear-off segments that tear off when the closure is opened for the first time, with spring tabs pointing against the closing direction, underneath the screw thread on the container neck, pointing in the closing direction sawtooth-like cams and an outwardly pointing bead on the lower part of the screw cap, characterized in that the tear-off segments and their connections
  • a) lie inside the screw cap,
  • b) are completely covered by the bead of the screw cap and
  • c) form a unit which can be processed together with the screw cap.

In einer bevorzugten Ausgestaltungsform ist diese Schraubverschlußanordnung so gestaltet, daß die Abreißsegmente über Soll-Bruchstellen an einem Trägerring befestigt sind, der bajonettartig mit der Schraubkappe verbunden ist.In a preferred embodiment, this screw closure arrangement is designed in such a way that the tear-off segments are attached via predetermined breaking points to a carrier ring which is connected in a bayonet-like manner to the screw cap.

In einer anderen bevorzugten Ausgestaltungsform ist die Schraubverschlußanordnung dadurch gekennzeichnet, daß die Abreißsegmente direkt über Soll-Bruchstellen mit der Schraubkappe verbunden sind.In another preferred embodiment, the screw closure arrangement is characterized in that the tear-off segments are connected directly to the screw cap via predetermined breaking points.

In den Zeichnungen sind bevorzugte Ausgestaltungsformen dargestellt.Preferred embodiments are shown in the drawings.

  • Figur 1 zeigt eine Vorderansicht einer bevorzugten Form des Verschlusses.Figure 1 shows a front view of a preferred form of closure.
  • Figur 2 zeigt eine Aufsicht auf die Behältermündung mit dem Originalitätssicherungsring.Figure 2 shows a plan view of the container mouth with the tamper-evident ring.
  • Figur 3 zeigt die Vorderansicht einer anderen bevorzugten Form des Verschlusses.Figure 3 shows the front view of another preferred form of closure.
  • Figur 4 zeigt eine Aufsicht auf den Verschluß nach Zeichnung 3.FIG. 4 shows a top view of the closure according to drawing 3.

Mit 1 ist darin der Behälterhals bezeichnet mit dem Schraubgewinde 2, den Nocken 3 und dem Absatz 4. 5 ist eine Schraubkappe mit dem Wulstrand 6, den Haltewinkeln 7 und den Haltestiften 8. 9 ist der Originalitätssicherungsring, bestehend aus dem Trägerring 10, den AbreißSegmenten 11, den Anbindungen 12, den Federlaschen 13, den Stützsegmenten 14 und den Haltenocken 15. 16 ist eine andere Form einer Schraubkappe, in der die Abreißsegmente 11 mit den Federlaschen 13 über die Anbindungen 12 direkt an den Wulstrand 6 der Schraubkappe befestigt sind. Mit 17 sind Beobachtungsfenster bezeichnet, durch die die Abreißsegmente 11 sichtbar sind.1 with the container neck is designated with the screw thread 2, the cams 3 and the paragraph 4. 5 is a screw cap with the bead 6, the brackets 7 and the retaining pins 8. 9 is the tamper-evident ring consisting of the carrier ring 10, the tear-off Segments 11, the connections 12, the spring tabs 13, the support segments 14 and the retaining cams 15. 16 is another form of a screw cap, in which the tear-off segments 11 with the spring tabs 13 are fastened via the connections 12 directly to the bead 6 of the screw cap. With 17 observation windows are designated, through which the tear-off segments 11 are visible.

In der erfindungsgemäßen Schraubverschlußanordnung mit Originalitätssicherung können die die Originalitätssicherung bewirkenden Elemente entweder, wie in den Figuren 3 und 4 gezeigt, fest mit der Schraubkappe verbunden sein oder können, wie in den Figuren 1 und 2 gezeigt, ein separates Teil bilden. In jedem Fall jedoch kann die Schraubkappe mit der Originalitätssicherung als Einheit verarbeitet werden, so daß eine Verarbeitung auf automatischen Abfüll- und Verschließanlagen möglich ist.In the screw closure arrangement according to the invention with tamper-evident securing, the elements which bring about tamper-evident securing can either be firmly connected to the screw cap, as shown in FIGS. 3 and 4, or, as shown in FIGS. 1 and 2, can form a separate part. In any case, however, the screw cap with the tamper-evident device can be processed as a unit, so that processing on automatic filling and closing systems is possible.

Im Falle des mehrteiligen Systems nach den Figuren 1 und 2 wird dies dadurch erreicht, daß am Wulstrand 6 der Schraubkappe 5 Haltewinkel 7 vorgesehen sind, in die die Haltenocken 15 des Originalitätssicherungsrings 9 bajonettverschlußartig einrasten können. Dazu wird der Originalitätssicherungsring 9 so in die Schraubkappe 5 eingesetzt, daß die Haltenocken 15 zwischen den Haltewinkeln 7 liegen, worauf durch eine kurze Drehung die Ealtenocken 15 gegen den Widerstand der biegsamen Haltestifte 8 in die Haltewinkel 7 eingerastet werden. Der Originalitätssicherungsring 9 ist damit gegen ein Herausfallen aus der Schraubkappe gesichert.In the case of the multi-part system according to FIGS. 1 and 2, this is achieved in that retaining brackets 7 are provided on the bead 6 of the screw cap 5, into which the retaining cams 15 of the tamper-evident ring 9 can snap in the manner of a bayonet lock. For this purpose, the tamper-evident ring 9 is inserted into the screw cap 5 in such a way that the retaining cams 15 lie between the retaining brackets 7, whereupon the snap cams 15 are snapped into the retaining bracket 7 against the resistance of the flexible retaining pins 8. The tamper-evident ring 9 is thus secured against falling out of the screw cap.

In dieser vereinigten Form liegt der Originalitätssicherungsring 9 innerhalb der Schraubkappe 5 und insbesondere die empfindlichen Abreißsegmente 11 werden durch den Wulstrand 6 gegen jegliche Belastungen bei Transport oder Handhabung der Schraubkappe mit Griginalitätssicherungsring geschützt. Die Anbindungen 12 können daher so schwach ausgelegt werden, daß zum späteren Öffnen des Verschlusses, wobei die Abreißsegmente abgerissen werden, keine große Kraftentfaltung notwendig ist.In this combined form, the tamper-evident ring 9 lies within the screw cap 5, and in particular the sensitive tear-off segments 11 are protected by the beaded edge 6 against any stresses during transport or handling of the screw cap with a tamper-evident ring. The connections 12 can therefore be designed so weak that the subsequent opening of the closure, wherein the Abreißsegmente be torn off, no big Kraftentfaltun g is required.

Beim Verschließen eines Behälters mit der den Originalitätssicherungsring 9 enthaltenden Schraubkappe 5 gleiten die Federlaschen 13 über die sägezahnartigen Nocken 3 des Behälterhalses 1. Der Behälter kann auf diese Weise manuell oder automatisiert ohne Zerstörung des Onginalitätssicherungssystems verschlossen werden. Im geschlossenen Zustand sind die Abreißsegmente 11 durch den am Behälterhals 1 vorgesehenen Absatz 4 verdeckt, so daß Manipulationen an den Abreißsegmenten 11 bzw. den Federlaschen 13, durch die bei vielen bekannten Verschlüssen auch ein Öffnen ohne Zerstörung der Originalitätssicherunc möglich ist, zuverlässig verhindert werden. Die Federlaschen 13 sind jetzt im Eingriff mit den sägezahnartigen Nocken 3. Wird daher die Schraubkappe 5 in öffnungsrichtung gedreht, so kann der Originalitätssicherungsring 9 diese Bewegung nicht mitmachen. Bei einer geringen Drehung der Schraubkappe 5 lösen sich deshalb zunächst die Haltenocken 15 aus den Haltewinkeln 7. Obwohl damit die Verbindung zwischen Schraubkappe 5 und Originalitätssicherungsring 9 gelöst ist, kann dieser nicht nach unten herausfallen, da er mit den Abreißsegmenten 11 auf dem Absatz 4 abgestützt ist. Wird die Schraubkappe 5 weiter in Öffnungsrichtung gedreht, werden die Haltenocken 15 mit dem Trägerring 10 von den Haltewinkeln 7 mitgenommen und es kommt zum Abreißen der Abreißsegmente 11. Da nur die Abreißsegmente 11 auf dem Absatz 4 abgestützt sind, nicht jedoch der Trägerring 10, fällt dieser nun nach unten heraus und es ist sofort erkennbar, daß ein Öffnunasversuch stattgefunden hat.When a container is closed with the screw cap 5 containing the tamper-evident ring 9, the spring tabs 13 slide over the sawtooth-like cams 3 of the container neck 1. In this way, the container can be closed manually or automatically without destroying the originality assurance system. In the closed state, the tear-off segments 11 are covered by the paragraph 4 provided on the container neck 1, so that tampering with the tear-off segments 11 or the spring tabs 13, by means of which many known closures can also be opened without destroying the tamper evident, can be reliably prevented. The spring tabs 13 are now in engagement with the sawtooth-like cams 3. If the screw cap 5 is therefore rotated in the opening direction, the tamper-evident ring 9 cannot take part in this movement. With a slight rotation of the screw cap 5, therefore, the holding cams 15 first detach from the holding brackets 7. Although the connection between the screw cap 5 and the tamper-evident ring 9 is thus loosened, it cannot fall out downward because it is supported on the paragraph 4 with the tear-off segments 11 is. Will the Screw cap 5 rotated further in the opening direction, the retaining cams 15 are carried along with the carrier ring 10 by the holding brackets 7 and the tear-off segments 11 tear off. Since only the tear-off segments 11 are supported on the shoulder 4, but not the carrier ring 10, the latter now falls downwards and it is immediately recognizable that an opening attempt has taken place.

Im Prinzip in der gleichen Weise funktioniert der Verschluß nach den Zeichnungen 3 und 4, bei dem die Abreißsegmente 11 mit Hilfe der Anbindungen 12 direkt an den Wulstrand E der Schraubkappe 16 angespritzt sind. Auch bei dieser Ausführungsform der erfindungsgemäßen Verschlußanordnung liegen die Abreißsegmente 11 vollständig innerhalb der Schraubkappe 16 und sind so gegen Beschädigungen bei Transport und Verarbeitung geschützt. Im Gegensatz zu der zuerst beschriebenen Verschlußanordnung wird hier jedoch die beim Drehen der Schraubkappe in Öffnungsrichtung erfolgende Zerstörung der Originalitätssicherung durch Abreißen der Abreißsegmente 11 durch die Abreißsegmente selbst optisch angezeigt. Dazu sind in der Schraubkappe 16 Beobachtungsfenster 17 vorgesehen, durch die man sofort erkennen kann, ob die Abreißsegmente 11 noch ordnungsgemäß an die Schraubkappe 16 angebunden sind oder nicht.In principle, the closure according to the drawings 3 and 4 functions in the same way, in which the tear-off segments 11 are injection-molded directly onto the bead edge E of the screw cap 16 with the aid of the connections 12. In this embodiment of the closure arrangement according to the invention, the tear-off segments 11 lie completely within the screw cap 16 and are thus protected against damage during transport and processing. In contrast to the closure arrangement described first, however, the destruction of the tamper-evident device when the screw cap is turned in the opening direction is optically indicated by the tear-off segments 11 being torn off by the tear-off segments themselves. For this purpose, observation windows 17 are provided in the screw cap 16, through which one can immediately see whether the tear-off segments 11 are still properly connected to the screw cap 16 or not.

Die Herstellung der Schraubverschlüsse mit Originalitätssicherung erfolgt in der Regel im Spritzgußverfahren aus einem thermoplastischen Kunstoff wie z.B. Polyäthylen oder, vorzugsweise, Polypropylen. Die Maße sind abgestimmt auf die zu verschließenden Glas-, Metall- oder KunststoffDehälter.The screw caps with tamper-evident protection are usually made by injection molding from a thermoplastic material such as Polyethylene or, preferably, polypropylene. The dimensions are matched to the glass, metal or plastic containers to be closed.

Im Falle des zweiteiligen Verschlusses werden die beiden Teile 5 und 9 jeweils für sich hergestellt und danach zu einer gemeinsam zu verarbeitenden Einheit zusammengefügt. Obwohl in beiden bevorzugten Ausführungsformen die Abreißsegmente 11 im Prinzip auch geschlossen, d.h. als Abreißring ausgeführt werden könnten, welche Form ebenfalls von der Erfindung umfaßt sein soll, ist doch die mehrteilige, in 3 - 4 Segmente unterteilte Form bevorzugt. Die Stützsegmente 14 sind bisher nicht erwähnt worden, da diese Teile zur Funktion der Originalitätssicherung nicht beitragen, sondern lediglich zur Versteifung des Ringes 9 dienen.In the case of the two-part closure, the two parts 5 and 9 are each manufactured for themselves and then assembled into a unit to be processed together. Although in both preferred embodiments the tear-off segments 11 are in principle also closed, i.e. could be designed as a tear-off ring, which form is also intended to be encompassed by the invention, since the multi-part form, divided into 3-4 segments, is preferred. The support segments 14 have not yet been mentioned, since these parts do not contribute to the function of tamper-evident protection, but only serve to stiffen the ring 9.

Hinsichtlich Gewindesteigung und -profil, ggf. vorgesehenen Dichtungen, Materialauswahl und Verformung richtet sich der Fachmann in üblicher Weise nach dem vorgesehenen Verwendungszweck.With regard to thread pitch and profile, any seals provided, material selection and deformation, the person skilled in the art customarily depends on the intended use.

Durch die erfindungsgemäße Schraubverschlußanordnung mit Originalitätssicherung steht somit ein Verschluß zur Verfugung, der nicht nur sehr zuverlässig selbst Öffnungsversuche an den damit verschlossenen Behältern anzeigt, sondern auch als komplette Einheit auf automatisierten Verschließanlagen verarbeitet werden kann, und der insbesondere einen hervorragenden Schutz sowohl gegen ungewollte Beschädigungen der Originalitätssicherung als auch gegen unerkannte Manipulationen an der Originalitätssicherung bietet.Due to the screw cap arrangement according to the invention with tamper-evident protection, a closure is thus available which not only very reliably indicates attempts to open the containers closed with it, but which can also be processed as a complete unit on automated closing systems, and which in particular offers excellent protection against unwanted damage to the Offers tamper evidence as well as against undetected manipulations of tamper evidence.

Der neue Verschluß kann in an sich bekannter Weise überall dort eingesetzt werden, wo eine Originalitätssicherung für Schraubverschlußanordnungen gewünscht wird.The new closure can be used in a manner known per se wherever tamper-evident securing for screw closure arrangements is desired.
