Description

ZUMISCH-VERSCHLUSSVORRICHTUNG FÜR EINEN BEHÄLTER  ZUMISCH CLOSURE DEVICE FOR A CONTAINER
Die Erfindung betrifft eine Verschlussvorrichtung für einen Behälter, insbesondere eine Getränkeflasche, wobei die Verschlussvorrichtung ein Deckelelement zum Verschließen des Behälters, eine an dem Deckelelement angeordneteThe invention relates to a closure device for a container, in particular a beverage bottle, wherein the closure device comprises a cover element for closing the container, one arranged on the cover element
Kammer und ein Innengehäuse aufweist, wobei die Kammer ein Kammerendstück mit einer mittels eines Verschlussmittels verschließbaren Ablassöffnung aufweist, wobei das Innengehäuse Öffnungsmittel zur Öffnung der Ablassöffnung aufweist, und wobei die Kammer relativ zu dem Innengehäuse von einer Schließposition in eine Ablassposition bewegbar ist, wobei in der Ablassposition ein Ablasskanal zwischen der Kammer und dem Behälter freigegeben ist, so dass ein in der Kammer bevorratetes Medium in den Behälter austreten kann. A chamber and an inner housing, wherein the chamber has a Kammerendstück with a closable by means of a closure means Ablassöffnung, wherein the inner housing opening means to the opening of the discharge opening, and wherein the chamber is movable relative to the inner housing from a closed position to a discharge position, wherein in Ablassposition a discharge channel between the chamber and the container is released, so that a stored in the chamber medium can escape into the container.
Verschlussvorrichtungen der vorgenannten Art sind im Stand der Technik be- kannt. Diese sind - wie der Behälter auch - üblicherweise aus Polyethylen (PE) oder Polypropylen (PP) hergestellt. Die Verschlussvorrichtungen dienen dazu, einen Behälter, beispielsweise eine Getränkeflasche, zu verschließen, und gleichzeitig eine Kammer zur separaten Speicherung von flüssigen oder pul- verförmigen Zutaten, beispielsweise Tee-Essenzen, bereitzustellen, so dass diese erst in dem Moment, in dem die Verschlussvorrichtung von dem Behälter entfernt wird, in den Behälter gegeben werden und dort, beispielsweise mit Wasser, in Berührung kommen und/ oder gemischt werden. Dies ist regelmäßig der Moment, in welchem ein Benutzer beispielsweise das in dem Behälter befindliche Getränk konsumieren möchte. Closure devices of the aforementioned type are known in the prior art. These are - like the container also - usually made of polyethylene (PE) or polypropylene (PP). The closure devices serve to close a container, for example a beverage bottle, and at the same time to provide a chamber for the separate storage of liquid or powdered ingredients, for example tea essences, so that they do not become active until the closure device of FIG the container is removed, placed in the container and there, for example, come into contact with water and / or mixed. This is usually the moment in which a user, for example, wants to consume the beverage in the container.
Die Druckschrift WO 2007/129116 AI betrifft beispielsweise eine Verschlussvorrichtung, bei welcher das Deckelelement eine in den Behälter hineinragende Wandung aufweist, welche eine Kammer zur Bevorratung des Mediums be- grenzt. Die Wandung dieser Kammer ist mit einem Kammerendstück verbunden, welches die Kammer endseitig nach Art einer Steckverbindung umgreift. Das Kammerendstück weist eine Ablassöffnung auf, in welcher ein an einem Innengehäuse angeordnetes Verschlusselement angeordnet ist. Bei einem Ab- schrauben des Deckelelementes von dem Behälter entfernt sich das Deckelelement und damit gleichzeitig auch die daran angeordnete Kammer von dem Innengehäuse. Dadurch wird das Verschlussmittel innerhalb der Ablassöffnung des Kammerendstücks verschoben, wobei ein Ablasskanal freigegeben wird und das in der Kammer bevorratete Medium in den Behälter austreten kann. The document WO 2007/129116 A1 relates, for example, to a closure device in which the cover element has a wall projecting into the container, which has a chamber for storing the medium. borders. The wall of this chamber is connected to a chamber end piece, which engages around the chamber end in the manner of a plug connection. The chamber end piece has a discharge opening in which a closure element arranged on an inner housing is arranged. When the cover element is unscrewed from the container, the cover element and thus at the same time the chamber disposed thereon are removed from the inner housing. Thereby, the closure means is displaced within the discharge opening of the Kammerendstücks, wherein a discharge passage is released and the stored in the chamber medium can escape into the container.
Nachteilig bei dieser vorbekannten Verschlussvorrichtung ist, dass Kammer und Deckelelement einstückig ausgebildet sind, so dass die Wandungen der Kammer - wie auch die des Deckelelementes - aus PP oder PE gebildet sind. Diese Kunststoffe bilden jedoch keine ausreichende Barriere für Gase wie Sau- erstoff oder Kohlendioxid. Darüber hinaus ist das vorbekannte Deckelelement relativ zeit- und kostenaufwendig in der Herstellung. A disadvantage of this known closure device is that the chamber and lid member are integrally formed, so that the walls of the chamber - as well as the lid member - are made of PP or PE. However, these plastics do not form a sufficient barrier to gases such as oxygen or carbon dioxide. In addition, the previously known cover element is relatively time consuming and expensive to manufacture.
Die WO 2012/175934 A2 betrifft eine Verschlussvorrichtung, welche ein Deckelelement und eine daran angeordnete Kammer aufweist. Die Kammer ist mit dem Material des Deckelelementes umspritzt. Diese Umspritzung ist ebenfalls material- und zeitaufwendig, da die Kammer bis zu dem Kammerendstück mit dem Material des Deckelelementes umspritzt werden muss, um die gewünschte Dichtigkeit, d. h. Barriereeigenschaft, der Kammer gegenüber Gasen wie beispielsweise Sauerstoff und Kohlendioxid zu gewährleisten. WO 2012/175934 A2 relates to a closure device which has a cover element and a chamber arranged thereon. The chamber is overmolded with the material of the cover element. This encapsulation is also material and time consuming, since the chamber must be encapsulated up to the Kammerendstück with the material of the cover member to the desired tightness, d. H. Barrier property to ensure the chamber against gases such as oxygen and carbon dioxide.
Es ist daher Aufgabe der Erfindung, eine Verschlussvorrichtung zu schaffen, bei welcher die Kammer und das Kammerendstück schnell, kostengünstig und besonders fluiddicht sowie gasdicht miteinander verbunden werden können. Diesbezüglich schlägt die Erfindung eine Verschlussvorrichtung nach dem Oberbegriff des Anspruchs 1 vor, bei welcher die Kammer und das Kammerendstück mittels einer an Kammer und Kammerendstück angespritzten Kunst- Stoffdichtung fluid- und gasdicht miteinander verbunden sind, wobei Kammer, Kammerendstück und Kunststoffdichtung aus dem gleichen Kunststoff gebildet sind. It is therefore an object of the invention to provide a closure device in which the chamber and the Kammerendstück can be quickly, inexpensively and particularly fluid-tight and gas-tight connected to each other. In this regard, the invention proposes a closure device according to the preamble of claim 1, in which the chamber and the chamber end are fluidly and gas-tightly connected to each other by means of an injection-molded at the chamber and chamber end piece of plastic material seal, said chamber, Kammerendstück and plastic seal formed from the same plastic are.
Gemäß der Erfindung kann die Kammer nun mit dem Kammerendstück und der Kunststoffdichtung als von dem Deckelelement unabhängige Einheit hergestellt werden. Dadurch ergibt sich zusätzlich der Vorteil, als Material für die Kammer, das Kammerendstück und die Kunststoffdichtung einen Kunststoff zu wählen, welcher von dem Material des Deckelelementes abweicht, insbesondere eine größere Dichte aufweist und / oder eine geeignete Barriere für beispiels- weise Sauerstoff und Kohlendioxid bietet. Durch die Erfindung wird also eine fluid- und gasdichte Einheit geschaffen, welche als solche nur noch mit dem Deckelelement verbunden werden muss, beispielsweise über eine einfache Klemmverbindung. Mittels der angespritzten Kunststoffdichtung können Kammer und Kammerendstück nun unmittelbar aus einem gas- und fluiddich- ten Material herstellt werden, so dass eine zusätzliche Abdichtung oder eine zusätzliche Verstärkung, beispielsweise durch eine großflächige Umspritzung mit dem Material des Deckelelementes, überflüssig ist. Dies ist insbesondere auch vorteilhaft, wenn, wie bevorzugt, die gefüllte Kammer gegenüber der Umgebung unter Überdruck steht. Der Überdruck kann geeignet durch ein Gaspolster erreicht sein. According to the invention, the chamber can now be manufactured with the chamber end piece and the plastic seal as a unit independent of the cover element. This additionally has the advantage of selecting as the material for the chamber, the chamber end piece and the plastic seal a plastic which deviates from the material of the cover element, in particular has a greater density and / or offers a suitable barrier for, for example, oxygen and carbon dioxide , The invention thus provides a fluid and gas-tight unit which, as such, only has to be connected to the cover element, for example via a simple clamping connection. By means of the molded plastic seal chamber and Kammerendstück can now be made directly from a gas- and fluid-tight material, so that an additional seal or an additional reinforcement, for example by a large-scale encapsulation with the material of the cover element is superfluous. This is particularly advantageous if, as is preferred, the filled chamber is under pressure with respect to the environment. The overpressure can be suitably achieved by a gas cushion.
Vorteilhaft kann die Kammer in einem zeitlich vorgelagerten Fertigungsschritt vollständig für die Montage an dem Deckelelement vorbereitet werden. Insbe- sondere kann die Kammer zuerst mit dem Kammerendstück und gegebenenfalls weiteren Dichtungselementen vorbereitet werden. Insbesondere kann beispielsweise zusätzlich ein zwischen Kammer und Kammerendstück und/ oder zwischen Kammerendstück und Ablassöffnung, d.h. Verschlussmit- tel, angeordnetes Dichtungselement (Dichtgummi) vormontiert werden. Durch das anschließende Anspritzen der erfindungs gemäßen Kunststoffdichtung sowohl an Kammer als auch an Kammerendstück werden diese gas- und fluid- dicht miteinander verbunden und bilden eine einstückige Kammereinheit, welche als solche in einem weiteren Herstellungsschritt mit dem Deckelelement verbunden werden kann. Durch das Anspritzen der Kunststoff dichtung an Kammer und Kammerendstück werden diese zumindest partiell aufgeweicht, so dass sich eine fluiddichte und gasdichte Verbindung von Kammer, Kunststoffdichtung und Kammerendstück ergibt. Kammer, Kammerendstück und Kunststoffdichtung sind gemäß der Erfindung aus dem gleichen Kunststoff, bevorzugt einem thermoplastischen Kunststoff, gebildet. Insbesondere wird vorgeschlagen, dass der Kunststoff eine Dichte zwischen 1,1 g/ cm3 und 1,5 g/ cm3, besonders bevorzugt zwischen 1,20 g/ cm3 und 1,45 g/ cm3, aufweist. Insbesondere kann der Kunststoff Polybutylen- terephthalat (PBT) sein. Alternativ wäre auch die Verwendung von Polyethyl- enterephthalat (PET) denkbar. Dadurch, dass sowohl Kammer und Kammerendstück als auch die Kunststoffdichtung aus dem gleichen Kunststoff gebildet sind, können diese besonders einfach durch bloßes Anspritzen der Kunststoffdichtung an die Kammer und das Kammerendstück miteinander verbunden werden. Durch das Anspritzen werden sowohl die Kammer als auch dasAdvantageously, the chamber can be completely prepared for mounting on the cover element in a temporally preceding production step. In particular, In particular, the chamber can first be prepared with the chamber end piece and optionally further sealing elements. In particular, for example, a sealing element (sealing rubber) arranged between the chamber and the chamber end piece and / or between the chamber end piece and the discharge opening, ie the closure means, can additionally be preassembled. By the subsequent injection molding of the plastic seal according to the invention both at the chamber and at the chamber end piece, these are gas-tight and fluid-tightly connected to one another and form an integral chamber unit, which as such can be connected to the cover element in a further production step. By injecting the plastic seal on the chamber and chamber end piece they are at least partially softened, so that there is a fluid-tight and gas-tight connection of chamber, plastic seal and Kammerendstück. Chamber, Kammerendstück and plastic seal are formed according to the invention of the same plastic, preferably a thermoplastic material. In particular, it is proposed that the plastic has a density between 1.1 g / cm 3 and 1.5 g / cm 3 , more preferably between 1.20 g / cm 3 and 1.45 g / cm 3 . In particular, the plastic may be polybutylene terephthalate (PBT). Alternatively, the use of polyethylene terephthalate (PET) would be conceivable. Characterized in that both chamber and chamber end piece and the plastic seal are formed from the same plastic, these can be particularly easily connected by merely molding the plastic seal to the chamber and the Kammerendstück. By spraying both the chamber and the
Kammerendstück zumindest in Teilbereichen aufgeweicht, so dass sich durch das darauffolgende Abkühlen des Kunststoffs eine fluiddichte und gasdichte Schweißverbindung ergibt. Vorteilhaft wird als Kunststoff Polybutylentereph- thalat (PBT) gewählt, welches im Stand der Technik regelmäßig als Material für die Kammer vorgesehen ist. Dies insbesondere, um die notwendige Barrierewirkung gegenüber Gasen wie Sauerstoff und Kohlendioxid sicherzustellen. Nunmehr kann zusätzlich auch das Kammerendstück aus PBT gebildet sein, so dass dieses keine Leckstelle für Fluide oder Gase darstellt. Zusätzlich wird durch die angespritzte Kunststoffdichtung eine weitere Erhöhung der Dichtigkeit erreicht und gleichzeitig auch die mechanische Verbindung zwischen Kammer und Kammerendstück - zusätzlich zu der Steckverbindung - gestärkt. Es wird zusätzlich vorgeschlagen, dass die Kammer zylinderförmig ausgebildet ist, wobei Kammerendstück und Kunststoffdichtung im Wesentlichen ringförmig ausgebildet sind. Durch eine solche geometrische Ausgestaltung ist es besonders einfach, die erfindungsgemäße Verschlussvorrichtung an einem zylinderförmigen Behälter, wie beispielsweise eine Getränkeflasche, anzupassen. Das Kammerendstück ist dabei ringförmig ausgebildet, wobei dieses zentral eine Ablassöffnung ausspart. Die Kunststoffdichtung ist ebenfalls ringförmig ausgebildet, so dass diese gleichermaßen formschlüssig an Kammerendstück und Kammer angelegt werden kann. Schließlich wird vorgeschlagen, dass das Kammerendstück endseitig derChamber end piece softened at least in some areas, so that there is a fluid-tight and gas-tight welded joint by the subsequent cooling of the plastic. Advantageously, as plastic polybutylene terephthalate Thalat (PBT), which is provided in the art regularly as a material for the chamber. This, in particular, to ensure the necessary barrier effect against gases such as oxygen and carbon dioxide. Now, in addition, the Kammerendstück PBT may be formed so that this is no leak for fluids or gases. In addition, a further increase in the tightness is achieved by the molded plastic seal and at the same time strengthened the mechanical connection between the chamber and Kammerendstück - in addition to the connector. It is additionally proposed that the chamber is cylindrical, wherein the chamber end and the plastic seal are substantially annular. By such a geometric configuration, it is particularly easy to adapt the closure device according to the invention on a cylindrical container, such as a beverage bottle. The Kammerendstück is annular, with this centrally spared a drain opening. The plastic seal is also annular, so that it can be equally form-fitting applied to Kammerendstück and chamber. Finally, it is proposed that the Kammerendstück end of the
Kammer formschlüssig in die Kammer eingesteckt ist, wobei zwischen Kammer und Kammerendstück ein Spalt zur Anordnung der Kunststoffdichtung ausgebildet ist. Sowohl die Wandung der Kammer als auch das Kammerendstück können dabei so ausgeformt sein, dass deren einander zugewandte Oberflächen nicht vollständig miteinander in Kontakt stehen, sondern beispielsweise besonders geformte Endbereiche aufweisen, welche einen Spalt zwischen einander ausbilden. In diesen Spalt kann das Material zur Ausbildung der Kunststoffdichtung eingespritzt werden, wodurch sich die Kontaktfläche zwischen Kunststoff dichtung und Kammer beziehungsweise Kunststoff dichtung und Kammerendstück vergrößert. Dadurch wird die mechanische Stabilität und Dichtheit der Verbindung von Kammer und Kammerendstück zusätzlich verstärkt. Chamber is positively inserted into the chamber, wherein between the chamber and Kammerendstück a gap for the arrangement of the plastic seal is formed. Both the wall of the chamber and the Kammerendstück can be formed so that their facing surfaces are not completely in contact with each other, but for example, have specially shaped end portions which form a gap between each other. In this gap, the material can be injected to form the plastic seal, whereby the contact surface between Plastic seal and chamber or plastic seal and chamber end increased. As a result, the mechanical stability and tightness of the connection of chamber and chamber end piece is additionally reinforced.

Fig. 1 eine erfindungsgemäße Verschlussvorrichtung mit einer an Kammer und Kammerendstück angespritzten Kunststoffdichtung in einer Schließp osition, 1 shows a closure device according to the invention with a molded-on chamber and chamber end piece plastic seal in a Schließp osition,
Fig. 2 Verschlussvorrichtung gemäß Fig. 1 in einer Ablassposition,  2 closure device according to FIG. 1 in a discharge position, FIG.
Fig. 3 Verschlussvorrichtung gemäß Fig. 1 in einer vollständig von einem Behälter getrennten Position. Fig. 3 closure device according to FIG. 1 in a completely separated from a container position.
Die in Figur 1 dargestellte Verschlussvorrichtung 1 ist bereits vormontiert auf einen Behälter 2 aufgeschraubt. Beispielsweise ist der Behälter 2 eine übliche Kunststoff-Getränkeflasche. The closure device 1 shown in Figure 1 is already pre-mounted screwed onto a container 2. For example, the container 2 is a common plastic beverage bottle.
Die Verschlussvorrichtung 1 weist ein Deckelelement 3, eine an dem Deckelelement 3 angeordnete Kammer 5 und ein an dem Behälter 2 angeordnetes Innengehäuse 4 auf. Der Behälter 2 ist über ein erstes Gewindepaar 14 mit dem Innengehäuse 4 verbunden. Das Innengehäuse 4 wiederum ist über ein zweites Gewindepaar 15 mit dem Deckelelement 3 verbunden. Die Kammer 5 ist beispielsweise mittels einer Klemmverbindung an dem Deckelelement 3 angeord- net, wobei sich das Material des Deckelelementes 3 lediglich über eine Teillänge der Gesamtlänge der Kammer 5 erstreckt. Im vorliegenden Beispiel bedeckt das Material des Deckelelementes 3 ungefähr ein Fünftel der Gesamtlänge der Seitenwandung der Kammer 5. An dem Innengehäuse 4 sind ein Öffnungsmittel 8 und ein Verschlussmittel 6 angeordnet, wobei Öffnungsmittel 8 und Verschlussmittel 6 gemäß diesem Ausführungsbeispiel als einteiliges Stopfenelement ausgebildet sind. Dieses Stopfenelement ragt in eine Ablassöffnung 7 der Kammer 5. Das Öffnungsmittel 8 ist gemäß dieser Ausführungsform dadurch mit dem Innengehäuse 4 ver- bunden, dass das Material des Innengehäuses 4 teilweise über einen Randbereich des Öffnungsmittels 8 gespritzt ist. The closure device 1 comprises a cover element 3, a chamber 5 arranged on the cover element 3 and a container 5 arranged on the container 2 Inner housing 4 on. The container 2 is connected via a first pair of threads 14 with the inner housing 4. The inner housing 4 in turn is connected to the cover element 3 via a second pair of threads 15. The chamber 5 is arranged, for example, by means of a clamping connection on the cover element 3, wherein the material of the cover element 3 extends over only a partial length of the overall length of the chamber 5. In the present example, the material of the cover element 3 covers approximately one fifth of the total length of the side wall of the chamber 5. On the inner housing 4, an opening means 8 and a closure means 6 are arranged, wherein opening means 8 and closure means 6 are formed according to this embodiment as a one-piece plug member. This plug element projects into a discharge opening 7 of the chamber 5. According to this embodiment, the opening means 8 is connected to the inner housing 4 in that the material of the inner housing 4 is partially injected over an edge region of the opening means 8.
Die Kammer 5 weist an deren dem Deckelelement 3 abgewandten Endbereich ein Kammerendstück 9 auf, welches ringförmig ausgebildet ist und eine Ab- lassöffnung 7 bereitstellt. Zwischen dem Kammerendstück 9 und dem in die Ablassöffnung 7 hineinragenden Verschlussmittel 6 des Stopfenelementes ist zusätzlich ein Dichtungselement 12, beispielsweise ein Dichtgummi oder ein Polymer mit gummiartigen Eigenschaften, insbesondere aus Nitril, angeordnet, welches die Ablassöffnung 7 in Verbindung mit dem Verschlussmittel 6 je nach der Position des Verschlussmittels 6 entweder verschließt oder freigibt. In der dargestellten Schließposition befindet sich innerhalb des engsten Öffnungsquerschnitts der Ablassöffnung 7 ein Vorsprung des Verschlussmittels 6, welcher die Ablassöffnung 7 fluid- und gasdicht verschließt. Bei der Herstellung der gezeigten Verschlussvorrichtung 1 wird vorteilhaft zuerst eine vorgefertigte Einheit aus einer Kammer 5, einem Kammerendstück 9, einer Kunststoffdichtung 10 und bevorzugt auch einem Dichtungselement 12 hergestellt. Dafür wird das Kammerendstück nach Art einer Steckverbindung in den offenen Endbereich der Kammer 5 eingesteckt. Das Kammerendstück 9 ist zusätzlich bevorzugt formschlüssig mit dem Dichtungselement 12 verbunden, welches die Kontaktbereiche zu der Kammer 5 einerseits und zu dem Verschlussmittel 6 andererseits abdichtet. Durch die Form der Endbereiche von Kammer 5 und Kammerendstück 9 bildet sich ein Spalt 11, in welchen Kunststoffmaterial eingespritzt wird, so dass sich eine Kunststoffdichtung 10 ausbildet. Durch die hohe Temperatur der anzuspritzenden Kunststoff dichtung 10 werden Kammer 5 und Kammerendstück 9 zumindest partiell aufgeschmolzen, insbesondere da diese aus dem gleichen Material hergestellt sind und somit den gleichen Schmelzpunkt aufweisen. Nach der Aushärtung ergibt sich eine Einheit aus Kammer 5, Kammerendstück 9, Kunststoff dichtung 10 und Dichtungselement 12. Diese Einheit kann nun mit dem Deckelelement 3 verbunden werden, beispielsweise mittels einer Klemmverbindung. Anschließend werden Deckelelement 3 und Innengehäuse 4 über das zweite Gewindepaar 15 miteinander verbunden. Die dadurch fertiggestellte Verschlussvorrichtung 1 wird dann mit dem Behälter 2 verbunden. Dazu wird das Innengehäuse 4 der Verschlussvorrichtung 1 mittels des ersten Gewindepaares 14 mit dem Behälter 2 verschraubt. The chamber 5 has, at its end region facing away from the cover element 3, a chamber end piece 9, which is of annular design and provides a discharge opening 7. A sealing element 12, for example a sealing rubber or a polymer with rubber-like properties, in particular nitrile, is additionally arranged between the chamber end piece 9 and the closure means 6 of the plug element projecting into the drain opening 7, said outlet opening 7 being connected to the closure means 6 in dependence on FIG Position of the closure means 6 either closes or releases. In the illustrated closed position is located within the narrowest opening cross-section of the discharge opening 7, a projection of the closure means 6, which closes the drain opening 7 fluid-tight and gas-tight. In the production of the closure device 1 shown, a prefabricated unit comprising a chamber 5, a chamber end piece 9, a plastic seal 10 and preferably also a sealing element 12 is advantageously produced first. For the chamber end piece is inserted in the manner of a connector in the open end of the chamber 5. The chamber end piece 9 is additionally preferably connected in a form-fitting manner to the sealing element 12, which seals the contact areas to the chamber 5 on the one hand and to the closure means 6 on the other hand. The shape of the end regions of chamber 5 and chamber end piece 9 forms a gap 11, in which plastic material is injected, so that a plastic seal 10 is formed. Due to the high temperature of the plastic seal 10 to be sprayed chamber 5 and 9 Kammerendstück at least partially melted, especially since they are made of the same material and thus have the same melting point. After curing, a unit of chamber 5, chamber end piece 9, plastic seal 10 and sealing element 12 results. This unit can now be connected to the lid member 3, for example by means of a clamping connection. Subsequently, cover element 3 and inner housing 4 are connected to each other via the second pair of threads 15. The thus completed closure device 1 is then connected to the container 2. For this purpose, the inner housing 4 of the closure device 1 is screwed by means of the first thread pair 14 with the container 2.
Figur 2 zeigt die Verschluss Vorrichtung 1 in einer Ablassposition, d.h. nach einer Betätigung der Verschluss Vorrichtung 1. Durch eine Öffnungsbewegung der Verschlussvorrichtung 1 relativ zu dem Behälter 2 (entlang des zweiten Ge- windepaares 15) wird das Deckelelement 3 und damit auch die an dem Deckelelement 3 angeordnete Kammer 5 von dem Innengehäuse 4 wegbewegt, d.h. gemäß der Figur 1 nach oben, wodurch die Position des Verschlussmittels 6 innerhalb der Ablassöffnung 7 der Kammer 5 verändert wird. Das Verschluss- mittel 6 ist bevorzugt stillstehend und der Behälter 2 wird relativ zu dem Verschlussmittel 6 bewegt. Dabei wird ein Ablasskanal 13 innerhalb des Öffnungsmittels 8 freigegeben, so dass ein in der Kammer 5 bevorratetes Medium in dem Behälter 2 austreten kann. Bei einer weiteren Abschraubbewegung des Deckelelementes 3 von dem Behälter 2 gelangen die zwischen Deckelelement 3 und Innengehäuse 4 ausgebildeten Gewinde in eine Endstellung, in welcher sich Deckelelement 3 und Innengehäuse 4 nicht weiter zueinander verdrehen können. Dadurch wird die Drehbewegung mittels der zwischen Innengehäuse 4 und Behälter 2 ausgebildeten ersten Gewinde 14 fortsetzt, so dass es schließlich zu einer vollständigen Abschraubung der Verschlussvorrichtung 1 von dem Behälter 2 kommt. FIG. 2 shows the closure device 1 in a release position, ie after an actuation of the closure device 1. By an opening movement of the closure device 1 relative to the container 2 (along the second position). Windepaares 15), the lid member 3 and thus also arranged on the lid member 3 chamber 5 is moved away from the inner housing 4, ie according to the figure 1 upwards, whereby the position of the closure means 6 is changed within the discharge opening 7 of the chamber 5. The closure means 6 is preferably stationary and the container 2 is moved relative to the closure means 6. In this case, a discharge channel 13 is released within the opening means 8, so that a stocked in the chamber 5 medium in the container 2 can escape. In a further unscrewing movement of the cover element 3 from the container 2, the threads formed between the cover element 3 and the inner housing 4 reach an end position in which the cover element 3 and the inner housing 4 can not rotate any further. As a result, the rotational movement is continued by means of the first thread 14 formed between the inner housing 4 and the container 2, so that finally a complete unscrewing of the closure device 1 from the container 2 occurs.
Die vollständig von dem Behälter 2 gelöste Verschlussvorrichtung 1 zeigt Figur 3. Dabei befindet sich das Verschlussmittel 6 innerhalb der Ablassöffnung 7 in einer Endstellung, in welcher die Ablassöffnung 7 mittels eines entsprechend ausgeformten Endbereiches des Verschlussmittels 6 verschlossen ist, so dass ein Nachtropfen aus der Kammer 5 verhindert wird. The closure device 1 completely detached from the container 2 is shown in FIG. 3. The closure means 6 is located within the outlet opening 7 in an end position in which the outlet opening 7 is closed by means of a correspondingly shaped end region of the closure means 6, so that dripping from the chamber 5 is prevented.
