Description

Die Erfindung bezieht sich auf einen Drehverschlußdeckel für Flüssig­keiten, Granulaten, Pulver usw. aufnehmende Gebinde mit einer Plom­biervorrichtung, die den aufgeschraubten Deckel mit einer Ratschverzahnung auf dem Flansch abdrehsicher festlegt und den Deckel nur durch eine erkennbare Veränderung an ihr freigibt.The invention relates to a screw cap for liquids, granules, powders, etc. receiving container with a sealing device that fixes the screwed-on lid with ratchet teeth on the flange and only releases the lid by a recognizable change to it.

Derartige Drehdeckelverschlüsse sind an sich bekannt; sie werden gefordert, um sowohl dem Abfüller als auch dem Benutzer eine Gewähr dafür zu bieten, daß das abgefüllte Gut hinsichtlich seiner Zusammensetzung dem entspricht, was vom Abfüller in das Gebinde eingefüllt wurde. An der Plombiervorrichtung oder dem Deckel in Verbindung mit der Plombiervorrichtung soll jederzeit erkennbar sein, wenn das Gebinde widerrechtlich angebrochen wurde.Such rotary lid closures are known per se; they are required in order to offer both the bottler and the user a guarantee that the filled goods correspond in terms of their composition to what was filled into the container by the bottler. On the sealing device or the lid in connection with the sealing device should be recognizable at any time if the container has been opened illegally.

Bei den bekannten Drehverschlußdeckeln mit Plombiervor­richtung ist an den Deckel selbst über durchreißbare Stege ein Kunststoffring angespritzt, der beim unbefugten Öffnen vom Deckel abbricht und dann abfällt. Einem wenig geschulten oder unachtsamen Benutzer fällt, da der Rastring einfach abfällt, möglicherweise überhaupt nicht auf, daß das Gebinde zuvor schon widerrechtlich ange­brochen wurde.In the known twist-off caps with sealing device, a plastic ring is molded onto the lid itself via tearable webs, which breaks off the lid when it is opened without authorization and then falls off. A less-trained or careless user may not notice at all that the container has already been opened illegally because the locking ring simply falls off.

Es ist Aufgabe der Erfindung, einen Drehverschlußdeckel der eingangs erwähnten Art zu schaffen, bei dem das widerrechtliche Öffnen eines Gebindes völlig erkennbar ist.It is an object of the invention to provide a screw cap of the type mentioned, in which the illegal opening of a container is completely recognizable.

Die gestellte Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Ratschverzahnung der Plombiervorrichtung an einem Kunststoffratschring 9 vorgesehen ist, der bei auf den Flansch aufsitzendem Deckel 1 zwischen dem Deckel 1 und dem Fuß des Flansches festgeklemmt ist und der über Kunststofffilmverbindungen 17 mit konzentrischen Spreng­ringteilen 15 verbunden ist, die den Deckel 1 umfassen, wobei der Deckel 1 mit Sperrgliedern 7 versehen ist, die nach außen greifen und Schneidkanten 31 aufweisen, die zwischen dem Ratschring 9 und den Sprengringteilen 15 in Umfangsrichtung auf die Kunststoffilmverbindung 17 gerichtet sind.The object is achieved in that the ratchet teeth of the sealing device is provided on a plastic ratchet ring 9 which is clamped between the cover 1 and the base of the flange when the cover 1 is seated on the flange and which is connected to concentric snap ring parts 15 via plastic film connections 17 , which comprise the cover 1, the cover 1 being provided with locking members 7 which reach outwards and have cutting edges 31 which are directed circumferentially between the ratchet ring 9 and the snap ring parts 15 onto the plastic film connection 17.

Wird der Drehverschlußdeckel mit dieser Plombiervorrich­tung in Öffnungsrichtung gedreht, dann schneiden die Schneidkanten der Sperrglieder die Kunststofffilmver­bindungen durch und trennen somit die Sprengringteile von dem Ratschring. Wenn nun dafür gesorgt ist, daß die Sperrglieder die Sprengringteile nicht völlig von dem Ratschring trennen können, dann zeigen die noch an dem Ratschring und an dem Deckel baumelnden Sprengringteile, daß das Gebinde vorher bereits geöffnet worden ist.If the screw cap is turned in the opening direction with this sealing device, the cutting edges of the locking members cut through the plastic film connections and thus separate the snap ring parts from the ratchet ring. If it is now ensured that the locking members cannot completely separate the snap ring parts from the ratchet ring, then the snap ring parts still dangling on the ratchet ring and on the lid show that the container has already been opened.

Nach einer weiteren Ausgestaltung der Erfindung ist vorge­sehen, daß die Sperrglieder 7 im Querschnitt dreieck­förmig ausgebildet sind, wobei eine erste Sperrglied­fläche 7a etwa in die Ebene fällt, in der sich auch die Filmverbindungen erstrecken. Durch die dreieckförmige Aus­bildung der Sperrglieder ergeben sich an den Sperrgliedern Schneidkanten, mit denen die Filmverbindungen beim Drehen des Deckels in Umfangsrichtung durchgeschnitten werden können.According to a further embodiment of the invention it is provided that the locking members 7 are triangular in cross section, a first locking member surface 7a falling approximately in the plane in which the film connections also extend. The triangular design of the locking members results in cutting edges on the locking members with which the film connections can be cut in the circumferential direction when the cover is turned.

Nach einer weiteren Ausgestaltung der Erfindung ist vorge­sehen, daß die erste Sperrgliedfläche 7a an dem Ratsch­ring 9 anliegt. Die Sperrglieder können damit über den Rand des Rastringes hinweg gleiten und finden damit eine gute Führung.According to a further embodiment of the invention, it is provided that the first locking member surface 7a rests on the ratchet ring 9. The locking members can thus slide over the edge of the locking ring and thus find good guidance.

Nach einer weiteren Ausgestaltung der Erfindung ist vorge­sehen, daß zwischen den Sprengringteilen 15 und dem Ratschring 9 Ausnehmungsbereiche 23 ohne Filmver­bindungen 17 vorgesehen sind, durch die die Sperrglieder 7 des ein getrenntes Kunststoffspritzteil bildenden Deckels 1 greifen, und daß die Sprengringteile 15 mit von Aus­nehmungsbereichen in sie hineinreichenden Aussparungen 25 versehen sind, in die zweite Sperrgliedflächen 7b der Sperrglieder 7 eingreifen. Die Sperrglieder können auf diese Weise beim Zusammendrücken von Plombiervorrichtung und Drehverschlußdeckel in die Ausnehmungen eingedrückt werden. Durch ein leichtes Verdrehen des Deckels gegen­über der Plombiervorrichtung rasten dann die Sperrglieder in die Aussparungen der Sprengringteile ein. Besonders günstig ist dabei, wenn nach einer weiteren Ausgestaltung der Erfindung vorgesehen ist, daß die Aussparungen 25 keilförmig gestaltet sind und die zweiten Sperrglied­flächen 7b,die dachförmig aneinander schließen, in die keilförmigen Aussparungen 25 einrasten.According to a further embodiment of the invention it is provided that between the snap ring parts 15 and the ratchet ring 9 recess areas 23 without film connections 17 are provided, through which the locking members 7 of the cover 1 forming a separate plastic injection part engage, and that the snap ring parts 15 with recess areas into them Recessing recesses 25 are provided, engage in the second locking member surfaces 7b of the locking members 7. In this way, the locking members can be pressed into the recesses when the sealing device and the rotary closure lid are pressed together. The locking members then snap into the recesses in the snap ring parts by slightly turning the cover relative to the sealing device. It is particularly advantageous if, according to a further embodiment of the invention, it is provided that the cutouts 25 are wedge-shaped and the second locking member surfaces 7b, which adjoin one another in a roof shape, snap into the wedge-shaped cutouts 25.

Um sicher zu stellen, daß die Sprengringteile nicht voll­ständig von dem Rastring abgetrennt werden und damit die zerstörte Plombiervorrichtung weiter an dem Deckel fest­halten, ist nach einer weiteren Ausgestaltung der Er­findung vorgesehen, daß die Sprengringteile 15 und der Ratschring 9 über kräftige Kunststoffbrücken 19 mitein­ander verbunden sind, die sich in Aufdrehrichtung unmit­telbar an den Rastplatz der Sperrglieder in den keil­förmigen Aussparungen 25 anschließen. Diese kräftigen Kunststoffbrücken sorgen für eine bleibend feste Ver­bindung zwischen den Sprengringteilen und dem Ratschring.In order to ensure that the snap ring parts are not completely separated from the locking ring and thus hold the destroyed sealing device further on the cover, it is provided according to a further embodiment of the invention that the snap ring parts 15 and the ratchet ring 9 are connected to one another via strong plastic bridges 19 which connect in the unscrewing direction directly to the rest area of the locking members in the wedge-shaped recesses 25. These strong plastic bridges ensure a permanently firm connection between the snap ring parts and the ratchet ring.

Nach einer weiteren Ausgestaltung der Erfindung ist vorge­sehen, daß zwischen den einzelnen Sprengringteilen 15 anschließend an die Ausnehmungsbereiche 23 Freiräume 21 vorgesehen sind, deren Länge in Umfangsrichtung mindestens der der Sperrglieder 7 entspricht. Diese Freiräume er­leichtern das Aufstecken des Deckels mit seinen Sperr­ gliedern auf die Plombiervorrichtung.According to a further embodiment of the invention, it is provided that between the individual snap ring parts 15, after the recess areas 23, free spaces 21 are provided, the length of which in the circumferential direction corresponds at least to that of the locking members 7. These free spaces make it easier to put on the cover with its locks structure on the sealing device.

Nach einer weiteren Ausgestaltung der Erfindung, wobei die als getrennte Teile gespritzen Sprengringteile und der Ratschring einerseits und der Deckel andererseits aus unterschiedlich eingefärbten Kunststoffen bestehen, ist vorgesehen, daß die Sprengringteile 15 den Deckel­rand 5 umgreifen und die eingerasteten Sperrglieder 7 an derer Farbgebung sichtbar zwischen den Sprengring­teilen 17 und dem Ratschring 9 hindurchgreifen. Besteht der Deckel beispielsweise aus einem schwarzen Kunststoff und die Plombiervorrichtung aus einem gelben Kunststoff, dann zeichnet sich sehr deutlich ab, wenn nach einem Drehen der Sperrglieder und damit einem Abschneiden der Sprengringteile diese vor dem schwarzen Deckel schräg und schief abstehen gegenüber einer vorherigen Anlage.According to a further embodiment of the invention, wherein the snap ring parts injection molded as separate parts and the ratchet ring on the one hand and the cover on the other hand consist of differently colored plastics, it is provided that the snap ring parts 15 encompass the cover edge 5 and the latching locking members 7 are visible between the colors thereof Reach out snap ring parts 17 and ratchet ring 9. For example, if the cover is made of black plastic and the sealing device is made of yellow plastic, it becomes very clear if, after turning the locking elements and thus cutting off the snap ring parts, they protrude diagonally and crookedly in front of the black cover compared to a previous system.

Die Erfindung wird anhand der Zeichnung näher erläutert.

  • Es zeigen:Fig. 1 einen Drehverschlußdeckel ohne Plombier­vorrichtung in Seitenansicht ;
  • Fig. 2 eine Plombiervorrichtung für den Deckel nach Fig.1 in Seitenansicht und teilweise geschnitten;
  • Fig. 3 den Deckel nach Fig. 1 mit aufgesetzter Plombier­vorrichtung nach Fig. 2 in Seitenansicht und teil­weise geschnitten;
  • Fig. 4 den Deckel nach Fig. 1 nach einem teilweise er­folgten Abtrennen der Sprengringteile der Plombier­vorrichtung.
The invention is explained in more detail with reference to the drawing.
  • The figures show: 1 is a side view of a screw cap without a sealing device;
  • 2 shows a sealing device for the lid according to FIG. 1 in a side view and partially in section;
  • 3 shows the lid according to FIG. 1 with the sealing device according to FIG. 2 in a side view and partially in section;
  • Fig. 4 shows the lid of Fig. 1 after a partial separation of the snap ring parts of the sealing device.

Fig. 1 zeigt einen Deckel 1, der mit Griffrippen 3 ver­sehen ist und der einen Deckelrand 5 aufweist. Der Deckel­rand 5 ist mit wenigstens einem Sperrglied 7 versehen, welches im Schnitt dreieckförmig ist und radial von dem Deckelrand absteht.1 shows a cover 1 which is provided with grip ribs 3 and which has a cover edge 5. The lid edge 5 is provided with at least one locking member 7, which is triangular in section and protrudes radially from the lid edge.

Fig. 2 zeigt eine Plombiervorrichtung für diesen Deckel. Diese Plombiervorrichtung besteht aus einem Ratschring 9, der an seiner Innenwand 11 mit Ratschnasen 13 versehen ist, die nicht näher dargestellt sind, da sie zum Stand der Technik gehören. Koaxial zu dem Ratschring 9 sind Sprengringteile 15 vorgesehen. Der Deckel 1 ist ebenso wie die Plombiervorrichtung nach Fig. 2 aus Kunststoff gespritzt. Dabei sind zwischen dem Ratschring 9 und den Sprengringteilen 15 Filmverbindungen 17 gespritzt, welche die Ratschringteile in unzerstörter Lage unmittelbar koaxial gegenüber dem Ratschring 9 festhalten. Es sind zusätzliche Verbindungsbrücken 19 vorgesehen, die kräftige Verbindungen zwischen den Sprengringteilen 15 und dem Ratschring herbeiführen.Fig. 2 shows a sealing device for this lid. This sealing device consists of a ratchet ring 9, which is provided on its inner wall 11 with ratchet 13, which are not shown in detail, since they belong to the prior art. Snap ring parts 15 are provided coaxially with the ratchet ring 9. Like the sealing device according to FIG. 2, the cover 1 is injection molded from plastic. In this case, 15 film connections 17 are injection molded between the ratchet ring 9 and the snap ring parts, which hold the ratchet ring parts in an undamaged position directly coaxially with respect to the ratchet ring 9. Additional connecting bridges 19 are provided which bring about strong connections between the snap ring parts 15 and the ratchet ring.

Zwischen den Sprengringteilen 15 befinden sich Freiräume 21. Weiterhin sind Ausnehmungsbereiche 23 vorgesehen, in dem die Filmverbindungen 17 weggelassen sind. Die Sprengringteile 15 haben noch keilförmige Aussparungen 25, die von den Ausnehmungsbereichen 23 in sie hineingeführt sind.There are free spaces 21 between the snap ring parts 15. Recess areas 23 are also provided, in which the film connections 17 are omitted. The snap ring parts 15 still have wedge-shaped recesses 25 which are guided into the recess regions 23.

Fig. 3 zeigt nun, wie der Deckel 1 und die Plombiervor­richtung nach Fig. 2 ineinander verhakt sind. Das Inein­anderverhaken kommt dadurch zu Stande, daß beim axialen Zusammenführen der Teile nach Fig. 1 und 2 in Richtung der Pfeile 27 die Sperrglieder 7 durch die Freiräume 21 hindurch in die Ausnehmungsbereiche 23 eingeschoben wer­den. Durch ein Verdrehen der Teile nach Fig. 1 und 2 gegeneinander, entgegen der Richtung der Pfeile 29, gleiten die Sperrglieder 7 mit ihren ersten Sperrglied­flächen 7a über die Oberkante 30 des Ratschringes hinweg in die Aussparungen 25 ein. Die Sperrglieder 7 liegen da­bei sehr verdrehsicher mit ihren dachförmig aneinander anschließenden zweiten Sperrgliedflächen 7b in den keil­förmigen Aussparungen 25. Die durch die Aussparungen vor­gegebenen Rastplätze liegen unmittelbar neben der Kunst­stoffbrücken 19. Die Länge der Freiräume 21 in Umfangs­richtung entspricht mindestens der der Sperrglieder 19.Fig. 3 shows how the lid 1 and the sealing device according to Fig. 2 are hooked together. The interlocking is achieved in that when the parts according to FIGS. 1 and 2 are brought together axially in the direction of arrows 27, the locking members 7 are inserted through the free spaces 21 into the recess areas 23. By rotating the parts according to FIGS. 1 and 2 against one another, counter to the direction of the arrows 29, the locking members 7 slide with their first locking member surfaces 7a over the upper edge 30 of the ratchet ring into the recesses 25. The locking members 7 are located in the wedge-shaped recesses 25 with their roof-like adjoining second locking member surfaces 7b in the wedge-shaped recesses 25. The rest areas specified by the recesses are located directly next to the plastic bridges 19. The length of the free spaces 21 in the circumferential direction corresponds at least to that of the locking members 19.

Der Deckel 1 kann beispielsweise aus schwarzem Kunststoff­gespritzt sein. Die Plombiervorrichtung nach Fig. 2 kann demgegenüber aus gelbem Kunststoff gespritzt sein. Auch andere Farbkombinationen können gewünscht und eingesetzt werden. Die Sprengringteile umgreifen, wie der Schnitt in Fig. 3 deutlich zeigt, den Deckelrand 5. Die einge­rasteten Sperrglieder 7 anderer Farbgebung greifen sicht­bar zwischen den Sprengringteilen 15 und dem Ratschring 9 hindurch.The cover 1 can, for example, be injection molded from black plastic. In contrast, the sealing device according to FIG. 2 can be injection molded from yellow plastic. Other color combinations can also be requested and used. As the section in FIG. 3 clearly shows, the snap ring parts encompass the lid edge 5. The latching locking elements 7 of different colors reach visibly between the snap ring parts 15 and the ratchet ring 9.

Aus Fig. 2 und 3 rechte Seite des Bildes ist anhand der dargestellten Schnitte die Lage und der Aufbau der Filmverbindungen dargestellt. Die Filmverbindungen haben eine im Querschnitt etwa 1-förmige Gestalt und in sie legt sich, wie aus Fig. 3 zu ersehen ist, der Rand 5 des Deckels 1 ein. Werden nun der Deckel 1 und die Plombier­vorrichtung nach Fig. 2 in Richtung der Pfeile 29 nach Fig. 3 gegeneinander verdreht, dann schneidet die Schneid­kante 31 des jeweiligen Sperrgliedes 7 die Filmverbindung zwischen dem rechtsbenachbarten Sprengringteil 17 und dem Ratschring 9 durch. Diese Durchtrennung ist in Fig. 4 durch die Trennstelle 33 angedeutet. Die Sprengringteile 15 stehen nun nach ihrem Abschneiden bogenförmig ab und hoch, so daß die Zerstörung der Plombiervorrichtung deut­lich erkennbar ist. Eine bleibende Verbindung zwischen den Sprengringteilen 15 und dem Ratschring 9 bilden die kräftigen Kunststoffbrücken 19.The position and the structure of the film connections are shown in FIGS. The film connections have an approximately 1-shaped cross-section and, as can be seen from FIG. 3, the edge 5 of the cover 1 is inserted into them. If the cover 1 and the sealing device according to FIG. 2 are now rotated relative to one another in the direction of the arrows 29 according to FIG. 3, the cutting edge 31 of the respective locking member 7 cuts through the film connection between the right-hand snap ring part 17 and the ratchet ring 9. This severing is indicated in FIG. 4 by the separation point 33. The snap ring parts 15 now stand out in an arc after being cut off and up, so that the destruction of the sealing device is clearly recognizable. The strong plastic bridges 19 form a permanent connection between the snap ring parts 15 and the ratchet ring 9.
