Abstract
Description
Die Erfindung bezieht sich auf einen Drehverschluß für Flüssigkeiten, Granulate, Pulver usw. aufnehmende Gebinde nach dem Oberbegriff des Anspruchs 1. 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 wiederrechtlich angebrochen wurde.The invention relates to a screw cap for liquids, granules, powders, etc. containing containers according to the preamble of claim 1. Such screw cap 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 when 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.
Aus dem Gebrauchsmuster G 8 534 321 ist ein Plombierverschluß bekannt, der aus einem Doppelring besteht, der bei Verletzung des Verschlusses in zwei Einzelteile zerfällt, wodurch die Plombierung aufgehoben ist. Auch hier besteht noch die Gefahr, daß einem unachtsamen Beobachter ein unbefugtes Öffnen nicht auffällt, da der abgetrennte Ring übersehen werden kann, bzw. daß er, da er über den Verschluß abgehoben werden kann, nicht mehr vorhanden ist.From the utility model G 8 534 321 a sealing closure is known, which consists of a double ring, which breaks into two individual parts when the closure is broken, whereby the sealing is removed. Here, too, there is still the danger that an unauthorized observer will not notice an unauthorized opening, since the separated ring can be overlooked or, since it can be lifted off via the closure, it is no longer present.
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 the opening, 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 vorgesehen ist, der bei auf den Flansch aufsitzendem Deckel zwischen dem Deckel und dem Fuß des Flansches festgeklemmt ist und der über Kunststofffilmverbindungen mit konzentrischen Sprengringteilen verbunden ist, die den Deckel umfassen, wobei der Deckel mit Sperrgliedern versehen ist, die nach außen greifen und Schneidkanten aufweisen, die zwischen dem Ratschring und den Sprengringteilen in Umfangsrichtung auf die Kunststoffilmverbindung gerichtet sind.The object is achieved in that the ratchet teeth of the sealing device is provided on a plastic ratchet ring which is clamped between the cover and the base of the flange when the cover is seated on the flange and which is connected via plastic film connections to concentric snap ring parts which comprise the cover , wherein the lid is provided with locking members which reach outwards and have cutting edges which are directed between the ratchet ring and the snap ring parts in the circumferential direction of the plastic film connection.
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 im Querschnitt dreieckförmig ausgebildet sind, wobei eine erste Sperrgliedfläche 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 are triangular in cross section, a first locking member surface 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 an dem Ratschring 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 rests on the ratchet ring. 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 und dem Ratschring Ausnehmungsbereiche ohne Filmverbindungen vorgesehen sind, durch die die Sperrglieder des ein getrenntes Kunststoffspritzteil bildenden Deckels greifen, und daß die Sprengringteile mit von Ausnehmungsbereichen in sie hineinreichenden Aussparungen versehen sind, in die zweite Sperrgliedflächen der Sperrglieder 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 keilförmig gestaltet sind und die zweiten Sperrgliedflächen, die dachförmig aneinander schließen, in die keilförmigen Aussparungen einrasten.According to a further embodiment of the invention it is provided that recess areas without film connections are provided between the snap ring parts and the ratchet ring, through which the locking members of the cover forming a separate plastic injection part engage, and that the snap ring parts are provided with recesses extending into them from recess areas into which engage second locking member surfaces of the locking members. 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 are wedge-shaped and the second locking member surfaces, which adjoin one another in a roof shape, snap into the wedge-shaped cutouts.
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 und der Ratschring über kräftige Kunststoffbrücken miteinander verbunden sind, die sich in Aufdrehrichtung unmittelbar an den Rastplatz der Sperrglieder in den keilförmigen Aussparungen 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 continue to hold the destroyed sealing device on the cover, it is provided according to a further embodiment of the invention that the snap ring parts and the ratchet ring are connected to one another via strong plastic bridges which are joined together Connect in the unscrewing direction directly to the rest area of the locking elements in the wedge-shaped recesses. 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 anschließend an die Ausnehmungsbereiche Freiräume vorgesehen sind, deren Länge in Umfangsrichtung mindestens der der Sperrglieder 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 free spaces are provided between the individual snap ring parts, the length of which corresponds in the circumferential direction at least to that of the locking members, following the recess areas. These free spaces make it easier to put the lid on with its locking elements 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 den Deckelrand umgreifen und die eingerasteten Sperrglieder an derer Farbgebung sichtbar zwischen den Sprengringteilen und dem Ratschring hindurchgreifen. Besteht der Deckel beispielsweise aus einem schwarzen Kunststoff und die Plombiervorrichtung aus einem gelbenAccording 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 are made of differently colored plastics, it is provided that the snap ring parts encompass the edge of the cover and the latching locking elements whose color is visible between the snap ring parts and the Reach through the ratchet ring. For example, the lid is made of black plastic and the sealing device is made of yellow
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.Plastic, it is 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.The invention is explained in more detail with reference to the drawing.

- 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, der mit Griffrippen versehen ist und der einen Deckelrand aufweist. Der Deckelrand ist mit wenigstens einem Sperrglied versehen, welches im Schnitt dreieckförmig ist und radial von dem Deckelrand absteht.Fig. 1 shows a lid which is provided with grip ribs and which has a lid edge. The edge of the lid is provided with at least one locking member, which is triangular in section and protrudes radially from the edge of the lid.
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
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
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 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 7.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
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
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 structure of the film connections are shown in FIGS. 2 and 3 on the right-hand side of the image using the cuts shown. 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
