Definitions

  • the invention relates to a closure device according to the features of the preamble of claim 1.
  • Closure devices of the aforementioned type are known in the prior art. These serve to close a container, for example a beverage bottle, and at the same time provide a chamber for the separate storage of liquid or powdery ingredients, for example tea essences, so that these do not immediately fill when filled with the contents of the container, i.e. H. for example water, come into contact and / or are mixed, but only at the moment when the closure device is removed from the container. This is usually the moment when a user wants to consume the beverage in the container.

  • the piercing of the membrane by means of the mandrel is effected by unscrewing the cover element from the inner housing arranged on the container.
  • the chamber arranged on the cover element is basically moved away from the mandrel.
  • a left-handed thread arranged between the cover element and the mandrel simultaneously causes the mandrel to move in the direction of the membrane until the mandrel cuts through the membrane.
  • the mandrel is longitudinally movable but non-rotatably mounted on the inner housing.
  • the closure device can finally be unscrewed from the container by means of the first thread arranged between the container and the inner housing.
  • a disadvantage of the closure device known in the prior art is that for a movement of the mandrel in the direction of the membrane, there must be axial mobility of the mandrel within the cover element with simultaneous torsional strength. This increases the proportion of elements movably arranged in the closure device, which on the one hand results in a more complex manufacture of the closure device and on the other hand could also cause the mandrel movably mounted in the cover element to tilt, which would impede the proper functioning of the closure device.
  • WO 2006/037244 A1 which is generic, a closure device is known in which the cover is screw-connected to the inner housing at a vertical distance from an area in which the inner housing is connected to the container mouth.

  • the cover element moves in the direction of the inner housing, i. H. with the container upright, while the rotary movement is then transferred to the first thread arranged between the container and the inner housing, so that the closure device can be completely unscrewed from the container.
  • the locking device i.e. specifically unscrewed the inner housing from the container.
  • the user does not need to change the direction of rotation of the cover element. Rather, the different threads cause the cover element to lower and then raise the cover element relative to the container with the same rotational movement of the cover element.

If the mandrel is needle-shaped, it is advisable to arrange it outside the axis of rotation of the membrane.
  • a sealing element is advantageously arranged on the side of the closure means facing away from the chamber. Because the chamber is sealed with the closure means during the closed position, the additional sealing element can be arranged outside the chamber. In this respect, the demands on the material of the sealing element are lower than if the sealing element comes into direct contact with the medium stored in the container.

As a result of that the second thread 11 is a left-handed thread, the cover element 4 is rotated further towards the container 2 during a conventional opening movement of the container 2 in the counterclockwise direction.

Description

Die Erfindung betrifft eine Verschlussvorrichtung nach den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a closure device according to the features of the preamble of claim 1.

Verschlussvorrichtungen der vorgenannten Art sind im Stand der Technik bekannt. Diese dienen dazu, einen Behälter, beispielsweise eine Getränkeflasche, zu verschließen, und gleichzeitig eine Kammer zur separaten Speicherung von flüssigen oder pulverförmigen Zutaten, beispielsweise Teeessenzen, bereitzustellen, so dass diese nicht unmittelbar beim Befüllen mit dem Inhalt des Behälters, d. h. beispielsweise Wasser, in Berührung kommen und/oder gemischt werden, sondern erst in dem Moment, in dem die Verschlussvorrichtung von dem Behälter entfernt wird. Dies ist regelmäßig der Moment, in welchem ein Benutzer das in dem Behälter befindliche Getränk konsumieren möchte.Closure devices of the aforementioned type are known in the prior art. These serve to close a container, for example a beverage bottle, and at the same time provide a chamber for the separate storage of liquid or powdery ingredients, for example tea essences, so that these do not immediately fill when filled with the contents of the container, i.e. H. for example water, come into contact and / or are mixed, but only at the moment when the closure device is removed from the container. This is usually the moment when a user wants to consume the beverage in the container.

Die im Stand der Technik bekannten Verschlussvorrichtungen bestehen regelmäßig aus einem Deckelelement, an welchem die Kammer angeordnet ist, und einem Innengehäuse. Die Verschlussvorrichtung wird in der Regel als Ganzes, d. h. vollständig vormontiert, auf den Behälter aufgeschraubt. Zu diesem Zweck weist das Innengehäuse ein mit dem Gewinde des Behälters formschlüssig korrespondierendes erstes Gewinde auf. Darüber hinaus sind Deckelelement und Innengehäuse über formschlüssig korrespondierende zweite Gewinde miteinander verbunden. Bei einem Öffnen des Behälters, d. h. einem Abschrauben des Deckelelementes, wird das Deckelelement relativ zu dem Innengehäuse bewegt. Dabei wird das Deckelelement von einer Schließposition in eine Ablassposition bewegt, in welcher Ablassposition ein in der Kammer bevorratetes Medium in den Behälter austreten kann.The closure devices known in the prior art regularly consist of a cover element, on which the chamber is arranged, and an inner housing. The closure device is usually as a whole, i.e. H. completely pre-assembled, screwed onto the container. For this purpose, the inner housing has a first thread that corresponds to the thread of the container in a form-fitting manner. In addition, the cover element and the inner housing are connected to one another via form-fitting corresponding second threads. When opening the container, i.e. H. unscrewing the cover element, the cover element is moved relative to the inner housing. The cover element is moved from a closed position to a drain position, in which drain position a medium stored in the chamber can escape into the container.

Die Druckschrift WO 2008/017890 A1 betrifft eine solche Verschlussvorrichtung, welche beim Losschrauben des Deckelelementes von dem damit verschlossenen Behälter ein in der Kammer befindliches Medium in den Behälter abgibt. Die Kammer ist in Bezug auf eine Schließposition mit einer Membran verschlossen. Diese Membran wird in der Ablassposition durch ein an dem Innengehäuse angeordnetes Öffnungselement, nämlich einen Dorn mit integriertem Ablasskanal, durchstoßen. Durch die Öffnung der Membran kann das in der Kammer befindliche Medium durch den Ablasskanal des Dorns in den Behälter fließen. Das Durchstoßen der Membran mittels des Dorns wird durch eine Abschraubbewegung des Deckelelementes von dem an dem Behälter angeordneten Innengehäuse bewirkt. Durch die Abschraubbewegung des Deckelelementes wird die an dem Deckelelement angeordnete Kammer grundsätzlich von dem Dorn wegbewegt. Durch ein zwischen dem Deckelelement und dem Dorn angeordnetes linkssteigendes Gewinde wird jedoch gleichzeitig eine Bewegung des Dorns in Richtung der Membran bewirkt bis der Dorn die Membran durchtrennt. Dazu ist der Dorn longitudinal beweglich, aber drehfest, an dem Innengehäuse gelagert. Mittels des zwischen Behälter und Innengehäuse angeordneten ersten Gewindes kann die Verschlussvorrichtung schließlich von dem Behälter abgeschraubt werden.The publication WO 2008/017890 A1 relates to such a closure device which, when the cover element is unscrewed, is closed from it Container releases a medium in the chamber into the container. The chamber is closed with a membrane with respect to a closed position. In the drain position, this membrane is pierced by an opening element arranged on the inner housing, namely a mandrel with an integrated drain channel. Through the opening of the membrane, the medium in the chamber can flow through the drain channel of the mandrel into the container. The piercing of the membrane by means of the mandrel is effected by unscrewing the cover element from the inner housing arranged on the container. As a result of the unscrewing movement of the cover element, the chamber arranged on the cover element is basically moved away from the mandrel. A left-handed thread arranged between the cover element and the mandrel simultaneously causes the mandrel to move in the direction of the membrane until the mandrel cuts through the membrane. For this purpose, the mandrel is longitudinally movable but non-rotatably mounted on the inner housing. The closure device can finally be unscrewed from the container by means of the first thread arranged between the container and the inner housing.

Nachteilig bei der im Stand der Technik bekannten Verschlussvorrichtung ist, dass für eine Bewegung des Dorns in Richtung der Membran eine axiale Beweglichkeit des Dorns innerhalb des Deckelelementes, bei gleichzeitiger Drehfestigkeit gegeben sein muss. Dadurch erhöht sich der Anteil der beweglich in der Verschlussvorrichtung angeordneten Elemente, was zum einen eine aufwendigere Herstellung der Verschlussvorrichtung zur Folge hat und zum anderen auch eine Verkantung des beweglich in dem Deckelelement gelagerten Dorns verursachen könnte, wodurch die einwandfreie Funktion der Verschlussvorrichtung behindert würde.A disadvantage of the closure device known in the prior art is that for a movement of the mandrel in the direction of the membrane, there must be axial mobility of the mandrel within the cover element with simultaneous torsional strength. This increases the proportion of elements movably arranged in the closure device, which on the one hand results in a more complex manufacture of the closure device and on the other hand could also cause the mandrel movably mounted in the cover element to tilt, which would impede the proper functioning of the closure device.

Aus der US 5,149,445 A ist eine Verschlussvorrichtung mit einem Deckelelement bekannt. Es ist nur ein Gewinde ausgebildet. Darüber hinaus ist auf die US 2009/321286 A1 zu verweisen, bei welcher an einer gleichen Wand des Innengehäuses sowohl innen- wie auch außenseitig Gewinde vorgesehen sind. Hierbei dient ein sekundäres Gewinde zum Befestigen auf dem Behälterhals und ein primäres Gewinde um eine äußere Kappe nach oben zu schrauben, um damit die ganze Kappe gegenüber dem Innengehäuse anzuheben und damit die Ablassöffnung freizugeben. Das primäre und sekundäre Gewinde sind gleichgängig.From the US 5,149,445 A a closure device with a cover element is known. Only one thread is formed. It is also on the US 2009/321286 A1 to refer to, in which threads are provided on the same wall of the inner housing both on the inside and on the outside. Here, a secondary thread is used for fastening on the neck of the container and a primary thread for screwing an outer cap upwards, in order to raise the entire cap against the inner housing and thus to open the drain opening. The primary and secondary threads are the same.

Aus der WO 2006/037244 A1 , die gattungsbildend ist, ist eine Verschlussvorrichtung bekannt, bei welcher der Deckel mit dem Innengehäuse vertikal beabstandet schraubverbunden ist gegenüber einem Bereich, in welchem das Innengehäuse mit der Behältermündung verbunden ist.From the WO 2006/037244 A1 , which is generic, a closure device is known in which the cover is screw-connected to the inner housing at a vertical distance from an area in which the inner housing is connected to the container mouth.

Ausgehend von dem zuletzt genannten Stand der Technik beschäftigt sich die Erfindung mit der Aufgabenstellung, die bekannte, zuletzt genannte Verschlusseinrichtung raumgünstig auszubilden.Starting from the last-mentioned prior art, the invention is concerned with the task of making the known, last-mentioned closure device space-saving.

Diese Aufgabe ist beim Gegenstand des Anspruches 1 gelöst, wobei darauf abgestellt ist, dass der Seitenrand im aufgeschraubten Zustand der Verschlusseinrichtung nach außen weisend ein innengehäuseseitiges zweites Teilgewinde trägt.This object is achieved with the subject matter of claim 1, with the aim being that the side edge, when the closure device is screwed on, has a second partial thread pointing outward on the inside of the housing.

Durch die Gegenläufigkeit der Gewinde zwischen Innengehäuse und Behälter bzw. zwischen Deckelelement und Innengehäuse ist auch das linkssteigende Gewinde in einen Bereich außerhalb des Behälters verlegt, nämlich an die Außenwandung der Behälteröffnung. Dadurch entfällt gleichzeitig eine bewegliche Lagerung des Öffnungselementes an dem Innengehäuse. Das Öffnungselement ist unmittelbar einteilig mit dem Innengehäuse ausgebildet. Die Herstellung der Verschlussvorrichtung ist besonders einfach und kostengünstig. Es kann nicht zu ungewünschten Verkantungen des beweglich gelagerten Öffnungselementes innerhalb der Auslassöffnung der Kammer kommen.Because the threads run in opposite directions between the inner housing and the container or between the cover element and the inner housing, the left-handed thread is also moved to an area outside the container, namely to the outer wall of the container opening. As a result, there is no need for a movable mounting of the opening element on the inner housing. The opening element is formed directly in one piece with the inner housing. The production of the closure device is particularly simple and inexpensive. It cannot undesired canting of the movably mounted opening element within the outlet opening of the chamber.

Die zweiten Gewinde, welche korrespondierend an Deckelelement und Innengehäuse angeordnet sind, sind als linkssteigende Gewinde ausgebildet und die ersten Gewinde, welche zwischen Innengehäuse und Behälter ausgebildet sind, sind als rechtssteigende Gewinde ausgebildet.The second threads, which are arranged correspondingly on the cover element and inner housing, are designed as left-handed threads and the first threads, which are formed between the inner housing and container, are designed as right-handed threads.

Durch diese Ausgestaltung wird das Deckelelement entlang des linkssteigenden Gewindes bei einer Rotationsbewegung entgegen dem Uhrzeigersinn auf das Innengehäuse zu bewegt, so dass das an dem Innengehäuse angeordnete Öffnungsmittel ein an der Kammer angeordnetes Verschlussmittel durchtrennen kann und somit das Medium, welches in der Kammer gespeichert ist, in den Behälter austreten kann. Der Nutzer der Verschlussvorrichtung kann den Behälter somit wie gewohnt durch eine Drehung gegen den Uhrzeigersinn aufschrauben. Dabei erfolgt zuerst eine Bewegung des Deckelelementes in Richtung des Innengehäuses, d. h. bei aufrecht stehendem Behälter nach unten, während anschließend eine Überleitung der Drehbewegung auf das zwischen Behälter und Innengehäuse angeordnete erste Gewinde erfolgt, so dass die Verschlussvorrichtung komplett von dem Behälter abgeschraubt werden kann. Durch die Betätigung dieses Rechtsgewindes wird die Verschlussvorrichtung, d.h. konkret das Innengehäuse von dem Behälter abgeschraubt.As a result of this configuration, the cover element is moved along the left-hand thread in a counterclockwise rotation towards the inner housing, so that the opening means arranged on the inner housing can cut through a closing means arranged on the chamber and thus the medium which is stored in the chamber. can leak into the container. The user of the closure device can thus unscrew the container as usual by turning it counterclockwise. First, the cover element moves in the direction of the inner housing, i. H. with the container upright, while the rotary movement is then transferred to the first thread arranged between the container and the inner housing, so that the closure device can be completely unscrewed from the container. By actuating this right-hand thread, the locking device, i.e. specifically unscrewed the inner housing from the container.

Der Nutzer braucht die Drehrichtung der Drehbewegung des Deckelelementes nicht zu ändern. Die unterschiedlichen Gewinde verursachen vielmehr bei derselben Drehbewegung des Deckelelementes zunächst ein Absenken des Deckelelementes und sodann ein Anheben des Deckelelementes relativ zu dem Behälter.The user does not need to change the direction of rotation of the cover element. Rather, the different threads cause the cover element to lower and then raise the cover element relative to the container with the same rotational movement of the cover element.

Es empfiehlt sich im Sinne der Erfindung, dass das zweite Teilgewinde zeitlich vor dem ersten Teilgewinde betätigbar ist. Dadurch nimmt die Verschlussvorrichtung vor dem tatsächlichen Abschrauben von dem Behälter zuerst die Ablassposition ein, in welcher das in der Kammer bevorratete Medium in den Behälter austreten kann. Dies bedeutet konkret, dass das Medium noch während des gesamten anschließenden Abschraubens aus dem Behälter austreten kann. Somit ist es möglich, dass die Kammer bei der endgültigen Trennung der Verschlussvorrichtung von dem Behälter vollständig entleert ist. Ein Nachtropfen aus der Kammer wird somit minimiert. Im Gegensatz zum Stand der Technik ist dies ein entscheidender Vorteil, da dort die Bewegungen entlang des rechtssteigenden Gewindes und des linkssteigenden Gewindes zeitgleich ablaufen. Dadurch ist die effektive Zeit, die für das Austreten des Mediums aus der Kammer in den Behälter zur Verfügung steht, unvorteilhaft verkürzt.It is recommended in the sense of the invention that the second partial thread can be actuated before the first partial thread. This takes the closure device Before actually unscrewing from the container, first enter the drain position in which the medium stored in the chamber can escape into the container. Specifically, this means that the medium can still escape from the container during the entire subsequent unscrewing. It is thus possible for the chamber to be completely emptied when the closure device is finally separated from the container. Dripping from the chamber is thus minimized. In contrast to the prior art, this is a decisive advantage, since there the movements along the right-hand thread and the left-hand thread run simultaneously. This disadvantageously shortens the effective time available for the medium to exit the chamber into the container.

Es wird vorgeschlagen, dass die Kammer eine mit einem Verschlussmittel versehene Ablassöffnung aufweist, welche mittels eines an dem Innengehäuse angeordneten Öffnungsmittels öffenbar ist. Somit weisen die an dem Deckelelement angeordnete Kammer und das Innengehäuse korrespondierende Elemente, nämlich ein Verschlussmittel und ein Öffnungsmittel, auf, welche bei einer Bewegung des Deckelelementes in Richtung des Innengehäuses erfindungsgemäß zusammenwirken. Bei der Rotationsbewegung des Deckelelementes entlang des zweiten Gewindes wird die Kammer in Richtung des Öffnungsmittels bewegt bis schließlich das Öffnungsmittel auf das Verschlussmittel einwirkt und somit das Verschlussmittel die in der Kammer ausgebildete Ablassöffnung freigibt.It is proposed that the chamber have a drain opening provided with a closure means, which can be opened by means of an opening means arranged on the inner housing. Thus, the chamber arranged on the cover element and the inner housing have corresponding elements, namely a closure means and an opening means, which interact according to the invention when the cover element is moved in the direction of the inner housing. During the rotational movement of the cover element along the second thread, the chamber is moved in the direction of the opening means until finally the opening means acts on the closing means and thus the closing means releases the drain opening formed in the chamber.

Gemäß einer Ausführungsvariante kann das Öffnungsmittel als Dorn ausgebildet sein. In Kombination kann das Verschlussmittel als eine die Ablassöffnung verschließende Membran ausgebildet sein. Dabei wirken der Dorn und die Membran vorteilhaft so miteinander, dass der Dorn die Membran durchsticht oder zerschneidet. Die Membran kann beispielsweise eine Metallfolie, beispielsweise Alufolie, sein. Alternativ eignen sich auch Membranen aus Kunststoff, beispielsweise PBT, so dass die Membran bevorzugt aus dem gleichen Material hergestellt ist wie die Kammer. Vorteilhaft ist die Membran an die Kammer angeschweißt. Der Dorn kann beispielsweise nadelförmig oder auch klingenförmig ausgebildet sein, wobei die Membran durch die rotierende Bewegung des Deckelelementes über dem Dorn rotiert, so dass vorteilhaft nicht nur eine punktförmige Einstichstelle entsteht, sondern die Membran möglichst großflächig zerstört wird, so dass die Ablassöffnung möglichst großflächig freigegeben wird. Sofern der Dorn nadelförmig ausgebildet ist, empfiehlt es sich, diesen außerhalb der Rotationsachse der Membran anzuordnen.According to one embodiment variant, the opening means can be designed as a mandrel. In combination, the closure means can be designed as a membrane closing the drain opening. The mandrel and the membrane advantageously work with one another such that the mandrel pierces or cuts the membrane. The membrane can be, for example, a metal foil, for example aluminum foil. Alternatively, plastic membranes are also suitable, for example PBT, so that the membrane is preferably made of the same material as the chamber. The membrane is advantageously welded to the chamber. The mandrel can, for example, be needle-shaped or also blade-shaped, the membrane rotating through the rotating movement of the cover element over the mandrel, so that advantageously not only a punctiform puncture point is created, but rather the membrane is destroyed over a large area, so that the drainage opening is released as far as possible becomes. If the mandrel is needle-shaped, it is advisable to arrange it outside the axis of rotation of the membrane.

Vorteilhaft ist auf der der Kammer abgewandten Seite des Verschlussmittels ein Dichtungselement angeordnet. Dadurch, dass die Kammer während der Schließposition mit dem Verschlussmittel versiegelt ist, kann das zusätzliche Dichtungselement außerhalb der Kammer angeordnet sein. Insofern sind die Ansprüche an das Material des Dichtungselementes geringer als wenn das Dichtungselement unmittelbar mit dem in dem Behälter bevorrateten Medium in Kontakt kommt. Vorteilhaft ist das Dichtungselement ein thermoplastisches Elastomer. Thermoplastische Elastomere (TPE) besitzen den Vorteil, dass diese geschweißt werden können, um beispielsweise wasserfeste Verbindungen zu erzeugen. Vorteilhaft ist das Dichtungselement dabei zwischen der Kammer und dem Öffnungsmittel angeordnet, wobei diese möglichst spaltfrei abgedichtet sind. Das Öffnungsmittel kann dabei insbesondere während der Bewegung von der Schließposition in die Ablassposition kontinuierlich mit dem Dichtungselement in Verbindung stehen, wobei das Öffnungsmittel einen Ablasskanal aufweist, durch welchen das in der Kammer angeordnete Medium hindurchfließen kann, um von der Kammer in den Behälter zu gelangen.A sealing element is advantageously arranged on the side of the closure means facing away from the chamber. Because the chamber is sealed with the closure means during the closed position, the additional sealing element can be arranged outside the chamber. In this respect, the demands on the material of the sealing element are lower than if the sealing element comes into direct contact with the medium stored in the container. The sealing element is advantageously a thermoplastic elastomer. Thermoplastic elastomers (TPE) have the advantage that they can be welded to produce, for example, waterproof connections. The sealing element is advantageously arranged between the chamber and the opening means, these being sealed as free of gaps as possible. The opening means can in particular be continuously connected to the sealing element during the movement from the closed position to the discharge position, the opening means having a discharge channel through which the medium arranged in the chamber can flow in order to get from the chamber into the container.

Gemäß einer weiteren Ausführungsform der Erfindung kann vorgesehen sein, dass das Verschlussmittel ein einteilig mit dem Öffnungsmittel ausgebildetes Stopfenelement ist. In diesem Fall erübrigt sich ein separates Verschlussmittel, welches die Ablassöffnung im Sinne einer Membran verschließt. Vielmehr können die Form der Ablassöffnung und die Form des Stopfenelements korrespondierend so zueinander ausgebildet sein, dass das Stopfenelement während der Bewegung von der Schließposition in die Ablassposition erst die Ablassöffnung vollständig verschließt und anschließend einen Ablasskanal freigibt, durch welchen das Medium aus der Kammer in den Behälter austreten kann.According to a further embodiment of the invention, it can be provided that the closure means is a stopper element which is formed in one piece with the opening means. In this case, there is no need for a separate closure means, which closes the drain opening in the sense of a membrane. Rather, the shape of the drain opening and the shape of the stopper element can be designed so that the stopper element completely closes the drain opening during the movement from the closed position into the drain position and then releases a drain channel through which the medium from the chamber into the container can leak.

Neben der zuvor dargestellten Verschlussvorrichtung für einen Behälter schlägt die Erfindung ebenso einen Behälter mit einer vorgenannten Verschlussvorrichtung vor, wobei die Behälteröffnung des Behälters ein erstes Gewinde aufweist, welches formschlüssig korrespondierend mit einem ersten Gewinde des Innengehäuses verbunden ist.In addition to the above-described closure device for a container, the invention also proposes a container with the aforementioned closure device, the container opening of the container having a first thread which is connected in a form-fitting manner to a first thread of the inner housing.

Darüber wird auch ein Verfahren zur Abgabe eines Mediums aus einer Verschlussvorrichtung in einen Behälter beschrieben, insbesondere aus einer wie zuvor dargestellten Verschlussvorrichtung, wobei die Verschlussvorrichtung ein Deckelelement zum Verschließen einer Behälteröffnung des Behälters, ein Innengehäuse und eine an dem Deckelelement angeordnete Kammer aufweist, wobei das Deckelelement bei einem Wechsel der Verschlussvorrichtung von einer Schließposition in eine Ablassposition in eine Richtung auf den Behälter zu bewegt wird, wodurch die an dem Deckelelement angeordnete Kammer auf das an dem Behälter angeordnete Innengehäuse zu bewegt wird, wobei ein an dem Innengehäuse angeordnetes Öffnungsmittel ein an der Kammer angeordnetes Verschlussmittel freigibt, wodurch ein in der Kammer befindliches Medium aus der Kammer in den Behälter austreten kann. Erfindungsgemäß wird somit ein Verfahren vorgeschlagen, bei welchem bei einer üblichen Öffnungsbewegung des Behälters, d. h. bei Rotation des Deckelelementes in Richtung gegen den Uhrzeigersinn, eine Bewegung des Deckelelementes in Richtung des Innengehäuses, d. h. des Behälters, erfolgt, wodurch schließlich das an dem Innengehäuse angeordnete Öffnungsmittel mit einem an der Kammer angeordneten Verschlussmittel wechselwirkt, in dem Sinne, dass das Verschlussmittel einen Ablasskanal freigibt, so dass ein in der Kammer befindliches Medium in den Behälter austreten kann. Insbesondere bietet es sich dabei an, dass das Deckelelement entlang eines linkssteigenden Gewindes in eine Richtung auf den Behälter zu bewegt wird.In addition, a method for dispensing a medium from a closure device into a container is described, in particular from a closure device as described above, the closure device having a lid element for closing a container opening of the container, an inner housing and a chamber arranged on the lid element, wherein the Lid element is moved in a direction towards the container when the closure device is changed from a closed position into a lowering position, as a result of which the chamber arranged on the cover element is moved towards the inner housing arranged on the container, with an opening means arranged on the inner housing one at the other Chamber arranged closure means releases, whereby a medium in the chamber can escape from the chamber into the container. According to the invention, a method is thus proposed in which during a normal opening movement of the container, ie when the cover element rotates in the counterclockwise direction, the cover element moves in the direction of the inner housing, ie the container, which ultimately results in the opening means arranged on the inner housing with one the closure means arranged in the chamber interacts in the sense that the closure means releases a discharge channel, so that a medium in the chamber can escape into the container. In particular, it is advisable that the cover element is moved in one direction towards the container along a left-hand thread.

Die Figuren 1 bis 3 zeigen unterschiedliche Ausführungsformen einer erfindungsgemäßen Verschlussvorrichtung. Diese unterscheiden sich zum einen durch die Ausbildung der an dem Deckelelement angeordneten Kammer und zum anderen durch die Art des Verschlussmittels und Öffnungsmittels.The Figures 1 to 3 show different embodiments of a closure device according to the invention. These differ on the one hand by the design of the chamber arranged on the cover element and on the other hand by the type of closure means and opening means.

Figur 1 zeigt eine Verschlussvorrichtung 1, welche an einem Behälter 2, beispielsweise einer Getränkeflasche, angeordnet ist. Die Verschlussvorrichtung 1 ist im Bereich der Behälteröffnung 3 auf den Behälter 2 aufgeschraubt. Die Verschlussvorrichtung 1 weist ein Deckelelement 4, ein Innengehäuse 5 sowie eine an dem Deckelelement 4 angeordnete Kammer 6 auf. Die Kammer 6 ist zumindest teilweise in dem Innengehäuse 5 angeordnet, wobei ein in vertikaler Richtung oberer Teilbereich der Kammer 6 aus dem Innengehäuse 5 heraus ragt. In der Kammer 6 befindet sich ein Medium, welches beispielsweise eine Flüssigkeit oder ein Pulver sein kann. Die Kammer 6 weist an ihrem unteren Ende eine Ablassöffnung 8 auf, welche mittels eines Verschlussmittels 7, hier einer Aluminiumfolie, verschlossen ist. Vorteilhaft ist das Verschlussmittel 7 an die Kammer 6 angeschweißt. Das Innengehäuse 5 weist ein Öffnungsmittel 9, hier ein Dorn, auf. Dieses Öffnungsmittel 9 ragt in der Schließposition der Verschlussvorrichtung 1 bevorzugt in die Ablassöffnung 8, jedoch im gegebenen Fall nur soweit, dass das Öffnungsmittel 9 das Verschlussmittel 7 nicht oder nur nicht verletzend berührt. Nicht verletzend berührt meint hiermit, dass keine Schädigung des Verschlussmittels eintritt, so dass es zu einem unbeabsichtigten Austreten des Mediums kommen kann. Eine gewisse Berührung kann aber gegebenenfalls eintreten. Die Ablassöffnung 8 kann gegenüber dem Öffnungsmittel 9 durch ein Dichtungselement 12 abgedichtet sein. Dieses ist dann ringförmig in die Ablassöffnung 8 eingelassen. Das Öffnungsmittel 9 weist darüber hinaus einen Ablasskanal 13 auf, durch welchen das in der Kammer 6 bevorratete Medium in geöffneter Stellung des Verschlussmittels 7 aus der Kammer 6 in den Behälter 2 strömen kann. Figure 1 shows a closure device 1, which is arranged on a container 2, for example a beverage bottle. The closure device 1 is screwed onto the container 2 in the region of the container opening 3. The closure device 1 has a cover element 4, an inner housing 5 and a chamber 6 arranged on the cover element 4. The chamber 6 is at least partially arranged in the inner housing 5, an upper partial region of the chamber 6 projecting out of the inner housing 5 in the vertical direction. In the chamber 6 there is a medium which can be, for example, a liquid or a powder. The chamber 6 has at its lower end an outlet opening 8, which is closed by means of a closure means 7, here an aluminum foil. The closure means 7 is advantageously welded to the chamber 6. The inner housing 5 has an opening means 9, here a mandrel. In the closed position of the closure device 1, this opening means 9 preferably protrudes into the drain opening 8, but in the given case only to such an extent that the opening means 9 does not touch the closing means 7, or does not touch it in an injuring manner. Non-injuriously means here that the closure means is not damaged, so that the medium can escape unintentionally. A certain touch may occur, however. The drain opening 8 can be sealed off from the opening means 9 by a sealing element 12. This is then let into the outlet opening 8 in a ring shape. The opening means 9 also has a drain channel 13 through which the medium stored in the chamber 6 can flow from the chamber 6 into the container 2 in the open position of the closure means 7.

Bei der Herstellung der in Figur 1 gezeigten Verschlussvorrichtung wird die Kammer 6 mit einem Folienelement 14 verschlossen. Dieses Folienelement 14 ist vorteilhaft an einen Randbereich der Kammer 6 angeschweißt oder angeklebt. Darüber hinaus ist das Folienelement 14 vorteilhaft ebenfalls an das Deckelelement 4 angeschweißt oder angeklebt. Zur Anbringung der Verschlussvorrichtung 1 an den Behälter 2 wird zuerst das Innengehäuse 5 mit integriertem Öffnungsmittel 9 auf den Behälter 2 aufgeschraubt. Zu diesem Zweck verfügt das Innengehäuse 5 über einen U-förmigen Randbereich, welcher an der zu der Außenwand des Behälters 2 gerichteten Seite ein erstes Gewinde 10 trägt. Der Behälter 2 verfügt über ein formschlüssig korrespondierendes erstes Gewinde 10, so dass das Innengehäuse 5 auf den Behälter 2 aufgeschraubt werden kann. Sodann wird das Deckelelement 4 mit daran angeordneter Kammer 6 auf das Innengehäuse 5 (und damit auch gleichzeitig auf den Behälter 2) aufgeschraubt. Dazu wird ein auf der Innenseite des Deckelelementes 4 angeordnetes zweites Gewinde 11 mit einem nach außen weisenden zweiten Gewinde 11 des Seitenrandes des Innengehäuses 5 in Eingriff gebracht. Das Deckelelement 4 wird soweit auf das Innengehäuse 5 geschraubt, bis ein an dem Deckelelement 4 angeordnetes Rastelement 16 in einen an dem Innengehäuse 5 angeordneten Vorsprung 15 greift. Dies entspricht einer Position, bei welcher das Öffnungsmittel 9 derart in die Ablassöffnung 8 der Kammer 6 eingreift, dass das in die Ablassöffnung 8 eingebrachte Verschlussmittel 7 nicht zerstört wird.In the manufacture of the Figure 1 shown closure device, the chamber 6 is closed with a film element 14. This film element 14 is advantageously welded or glued to an edge region of the chamber 6. In addition, the film element 14 is also advantageously attached to the cover element 4 welded or glued. To attach the closure device 1 to the container 2, the inner housing 5 with integrated opening means 9 is first screwed onto the container 2. For this purpose, the inner housing 5 has a U-shaped edge region which carries a first thread 10 on the side facing the outer wall of the container 2. The container 2 has a form-fitting corresponding first thread 10, so that the inner housing 5 can be screwed onto the container 2. Then the cover element 4 with the chamber 6 arranged thereon is screwed onto the inner housing 5 (and thus simultaneously onto the container 2). For this purpose, a second thread 11 arranged on the inside of the cover element 4 is brought into engagement with an outwardly pointing second thread 11 of the side edge of the inner housing 5. The cover element 4 is screwed onto the inner housing 5 until a catch element 16 arranged on the cover element 4 engages in a projection 15 arranged on the inner housing 5. This corresponds to a position in which the opening means 9 engages in the drain opening 8 of the chamber 6 in such a way that the closure means 7 introduced into the drain opening 8 is not destroyed.

Figur 2 zeigt eine zweite Ausführungsform einer erfindungsgemäßen Verschlussvorrichtung 1, welche anstelle einer mit einem Folienelement 14 verschlossenen Kammer 6 eine - abgesehen von der Ablassöffnung 8 - vollständig verschlossene Kammer 6 aufweist. Diese Kammer 6 ist von dem Material des Deckelelementes 4 zylinderförmig umspritzt, so dass Kammer 6 und Deckelelement 4 fest miteinander verbunden sind. Im Übrigen ist die Ausgestaltung wie zuvor in Bezug auf die Verschlussvorrichtung 1 gemäß Figur 1 dargestellt. Figure 2 shows a second embodiment of a closure device 1 according to the invention which, instead of a chamber 6 closed with a film element 14, has a chamber 6, which is completely closed apart from the outlet opening 8. This chamber 6 is overmolded in a cylindrical shape by the material of the cover element 4, so that the chamber 6 and cover element 4 are firmly connected to one another. Otherwise, the configuration is as previously in relation to the closure device 1 according to FIG Figure 1 shown.

Figur 3 zeigt eine Verschlussvorrichtung 1 gemäß einer dritten Ausführungsvariante. Diese Verschlussvorrichtung 1 verfügt über eine Kammer 6, welche wie in Figur 2 dargestellt ausgebildet ist, d. h. - abgesehen von der Ablassöffnung 8 - vollständig geschlossen ist. Die Kammer 6 ist von dem Material des Deckelelementes 4 zylinderförmig umspritzt, so dass Kammer 6 und Deckelelement 4 fest miteinander verbunden sind. Im Gegensatz zu einem separaten Verschlussmittel 7 und einem separaten Öffnungsmittel 9 verfügt die Verschlussvorrichtung 1 gemäß Figur 3 über ein einteilig ausgebildetes Stopfenelement, welches sowohl ein Verschlussmittel 7 als auch ein Öffnungsmittel 9 aufweist. Das Stopfenelement ist an dem Innengehäuse 5 angeordnet, wobei zumindest das Verschlussmittel 7 als oberer Endbereich des Stopfenelementes in die der Kammer 6 zugeordnete Ablassöffnung 8 ragt. In der Ablassöffnung 8 ist ein Dichtungselement 12 angeordnet, welches je nach der Position des Verschlussmittels 7 an diesem anliegt oder nicht. In Figur 3 ist die Schließposition der Verschlussvorrichtung 1 dargestellt. In dieser liegt das Verschlussmittel 7 mit einem verbreiterten Endbereich an dem Dichtungselement 12 an und verschließt den Ablasskanal 13, so dass das in der Kammer 6 bevorratete Medium nicht ausströmen kann. In einer nicht dargestellten Ablassposition der Verschlussvorrichtung 1 ist das Verschlussmittel 7 hingegen weiter in die Kammer 6 hineinbewegt (in Figur 3 "nach oben"), so dass der verbreiterte Endbereich des Verschlussmittels 7 nicht mehr an dem Dichtungselement 12 anliegt und der Ablasskanal 13 freigegeben ist. Figure 3 shows a closure device 1 according to a third embodiment. This closure device 1 has a chamber 6, which as in Figure 2 is shown, that is - apart from the drain opening 8 - is completely closed. The chamber 6 is made of the material of the Cover element 4 molded around in a cylinder shape, so that chamber 6 and cover element 4 are firmly connected. In contrast to a separate closure means 7 and a separate opening means 9, the closure device 1 according to FIG Figure 3 via a one-piece plug element which has both a closure means 7 and an opening means 9. The stopper element is arranged on the inner housing 5, with at least the closing means 7, as the upper end region of the stopper element, projecting into the discharge opening 8 assigned to the chamber 6. In the drain opening 8, a sealing element 12 is arranged, which, depending on the position of the closure means 7, bears against it or not. In Figure 3 the closed position of the closure device 1 is shown. In this, the closure means 7 abuts the sealing element 12 with a widened end region and closes the drain channel 13, so that the medium stored in the chamber 6 cannot flow out. In a drain position (not shown) of the closure device 1, however, the closure means 7 is moved further into the chamber 6 (in FIG Figure 3 "upwards"), so that the widened end region of the closure means 7 is no longer in contact with the sealing element 12 and the drain channel 13 is released.

Im Folgenden wird die Funktionsweise der Verschlussvorrichtung 1 anhand der Figuren 4 bis 6 näher erläutert. Die Figuren 4 bis 6 betreffen die in Figur 1 gezeigte Ausführungsform.The mode of operation of the closure device 1 is described below with reference to FIG Figures 4 to 6 explained in more detail. The Figures 4 to 6 concern the in Figure 1 shown embodiment.

Die in Figur 4 dargestellte Verschlussvorrichtung 1 befindet sich in einer Ablassposition. Ausgehend von der in Figur 1 dargestellten Schließposition wird diese Ablassposition erreicht, in dem das Deckelelement 4 in Richtung des Behälters 2 bewegt wird, wobei die Kammer 6 weiter in das Innengehäuse 5 bewegt wird. Dies geschieht durch eine Rotation des Deckelelementes 4 entlang des zwischen Deckelelement 4 und Innengehäuse 5 ausgebildeten zweiten Gewindes 11, welches als linkssteigendes Gewinde ausgebildet ist. Dadurch, dass das zweite Gewinde 11 ein linkssteigendes Gewinde ist, wird das Deckelelement 4 bei einer üblichen Öffnungsbewegung des Behälters 2 in Richtung gegen den Uhrzeigersinn weiter auf den Behälter 2 zu gedreht. Für den Benutzer ergibt sich jedoch die übliche Betätigungsweise während eines Öffnungsvorgangs gegen den Uhrzeigersinn, so dass hierdurch keine abweichende Handhabung beachtet werden muss. Durch die Bewegung des Deckelelementes 4 auf den Behälter 2 zu wird gleichzeitig auch die an dem Deckelelement 4 angeordnete Kammer 6 weiter in den Behälter 2 hineinbewegt. Dadurch gelangt das in der Ablassöffnung 8 der Kammer 6 angeordnete Verschlussmittel 7 in Kontakt mit dem an dem Innengehäuse 5 angeordneten Öffnungsmittel 9. Das Öffnungsmittel 9 ist wie zuvor erläutert ein Schneidelement, welches einen zentralen Ablasskanal 13 aufweist, durch welchen Medium aus der Kammer 6 in den Behälter 2 strömen kann, sofern das in der Ablassöffnung 8 eingebrachte Verschlussmittel 7 zerstört wird. Durch die Rotation des Deckelelementes 4 wird gleichzeitig auch das Verschlussmittel 7 relativ zu dem Öffnungsmittel 9 rotiert, so dass sich eine großflächige im Wesentlichen runde Öffnung innerhalb der Ablassöffnung 8 der Kammer 6 ergibt. Das Deckelelement 4 ist in dieser Ablassposition wie maximal möglich auf das Innengehäuse 5 und damit den Behälter 2 aufgeschraubt.In the Figure 4 The closure device 1 shown is in a lowering position. Starting from the in Figure 1 shown closing position, this drain position is reached by moving the cover element 4 in the direction of the container 2, the chamber 6 being moved further into the inner housing 5. This is done by rotating the cover element 4 along the second thread 11 formed between the cover element 4 and the inner housing 5, which is designed as a left-handed thread. As a result of that the second thread 11 is a left-handed thread, the cover element 4 is rotated further towards the container 2 during a conventional opening movement of the container 2 in the counterclockwise direction. For the user, however, there is the usual way of actuation during an opening process counterclockwise, so that no different handling has to be observed as a result. Due to the movement of the cover element 4 towards the container 2, the chamber 6 arranged on the cover element 4 is simultaneously moved further into the container 2. As a result, the closure means 7 arranged in the discharge opening 8 of the chamber 6 comes into contact with the opening means 9 arranged on the inner housing 5. As previously explained, the opening means 9 is a cutting element which has a central discharge channel 13, through which medium from the chamber 6 in can flow the container 2, provided that the closure means 7 introduced into the drain opening 8 is destroyed. Due to the rotation of the cover element 4, the closure means 7 is simultaneously rotated relative to the opening means 9, so that there is a large, essentially round opening within the drain opening 8 of the chamber 6. In this drain position, the cover element 4 is screwed onto the inner housing 5 and thus the container 2 as much as possible.

In der zeichnerischen Darstellung hat sich die Position des nach außen ragenden Gewindevorsprungs der Kammer 5 zwischen Fig. 1 und Fig. nicht geändert. Dies ist auf die Tatsache zurückzuführen, dass die Kammer 5 ihre Stellung in Auf- bzw. Abschraubrichtung zwischen Fig. 1 und Fig. 5 auch nicht geändert hat. Vielmehr ist der Gewindevorsprung nur zufolge der Drehung von der entsprechenden Ausnehmung an der Innenwand des Deckelelementes 4 überlaufen worden, was entsprechend in derselben Schnittebene immer zu einer selben Relativanordnung zueinander führt.In the drawing, the position of the outwardly projecting thread projection of the chamber 5 has between Fig. 1 and Fig. not changed. This is due to the fact that the chamber 5 between in the screwing or unscrewing direction Fig. 1 and Fig. 5 hasn't changed either. Rather, the thread projection has only been overrun due to the rotation of the corresponding recess on the inner wall of the cover element 4, which correspondingly always leads to the same relative arrangement in the same cutting plane.

Figur 5 zeigt die erfindungsgemäße Verschlussvorrichtung 1 während des Abschraubens von dem Behälter 2. Durch eine weitere Drehung des Deckelelementes 4 in eine Richtung entgegen dem Uhrzeigersinn wird das Innengehäuse 5 und damit auch das an dem Innengehäuse 5 angeordnete Deckelelement 4 von dem Behälter 2 abgeschraubt. Dadurch, dass die zwischen Innengehäuse 5 und Behälter 2 ausgebildeten ersten Gewinde 10 als rechtssteigende Gewinde ausgebildet sind, wird die Verschlussvorrichtung 1 insgesamt von dem Behälter 2 weg bewegt. Während dieses Abschraubvorgangs kann das in der Kammer 6 gespeicherte Medium vollständig in den Behälter 2 entweichen. Figure 5 shows the closure device 1 according to the invention while being unscrewed from the container 2. By further turning the cover element 4 in a counterclockwise direction, the inner housing 5 and thus also the cover element 4 arranged on the inner housing 5 are unscrewed from the container 2. Because the first threads 10 formed between the inner housing 5 and the container 2 are designed as right-hand threads, the closure device 1 is moved away from the container 2 as a whole. During this unscrewing process, the medium stored in the chamber 6 can completely escape into the container 2.

Figur 6 schließlich zeigt die Verschlussvorrichtung in einem Zustand, in welchem die Verschlussvorrichtung 1 vollständig von dem Behälter 2 getrennt ist. Dabei sind alle Komponenten der Verschlussvorrichtung 1, nämlich insbesondere das Deckelelement 4 mit der daran angeordneten Kammer 6 und das Innengehäuse 5 von dem Behälter 2 gelöst. Figure 6 finally shows the closure device in a state in which the closure device 1 is completely separated from the container 2. All components of the closure device 1, namely in particular the cover element 4 with the chamber 6 arranged thereon and the inner housing 5, are detached from the container 2.

In Bezug auf die in den Figuren 2 und 3 dargestellten Verschlussvorrichtungen 1 funktioniert die Erfindung entsprechend analog. Herauszustellen ist dabei jeweils, dass die Verschlussvorrichtung 1 über stets den gleichen Gewindemechanismus von einer Schließposition in eine Ablassposition übergeleitet wird. Dieser Gewindemechanismus beinhaltet ein linkssteigendes Gewinde, welches für die Bewegung des Deckelelementes 4 in Richtung des Innengehäuses 5 sorgt, und ein rechtsteigendes Gewinde, welches schließlich für die Trennung der Verschlussvorrichtung 1, insbesondere dem Innengehäuse 5, von dem Behälter 2 sorgt.Regarding those in the Figures 2 and 3rd Shown locking devices 1, the invention works accordingly analog. It should be emphasized in each case that the closure device 1 is always transferred from a closed position to a lowering position via the same thread mechanism. This thread mechanism includes a left-hand thread, which ensures the movement of the cover element 4 in the direction of the inner housing 5, and a right-hand thread, which finally ensures the separation of the closure device 1, in particular the inner housing 5, from the container 2.

Gemäß Figur 3 funktioniert die Öffnung der Ablassöffnung 8 nicht über korrespondierende Verschlussmittel 7 und Öffnungsmittel 9, welche als Membran und Dorn ausgebildet sind, sondern vielmehr über ein einteiliges Stopfenelement, welches sowohl die Funktion des Verschlussmittels 7 als auch des Öffnungsmittels 9 übernimmt. Je nach der Stellung des Stopfenelements innerhalb der Ablassöffnung 8 wird entweder ein zwischen Stopfenelement und Dichtungselement 12 ausgebildeter Ablasskanal 13 verschlossen oder geöffnet.According to Figure 3 the opening of the drain opening 8 does not work via corresponding closure means 7 and opening means 9, which are designed as a membrane and mandrel, but rather via a one-piece plug element, which functions both the closure means 7 and the opening means 9 takes over. Depending on the position of the plug element within the drain opening 8, either a drain channel 13 formed between the plug element and the sealing element 12 is closed or opened.
