Mittels eines Betätigungselements kann Druck auf den Tablettenhalter ausgeübt werden, so dass eine dem Behälterinhalt zugewandte Seitenwand des Tablettenhalters aufbricht und die Tablette dem Inhalt des Behälters zugebbar ist. Anschließend kann die Ringmanschette abgeschraubt werden und der Inhalt ist aus dem Behälter entnehmbar. Um ein unbeabsichtigtes Zugeben der Tablette zu vermeiden, ist das Betätigungsmittel im Ausgangszustand durch eine Schutzkappe unzugänglich abgedeckt. Im Ausgangszustand ist die Tablette in dem Tablettenhalter gekapselt, insbesondere flüssigkeitsdicht verschlossen.From WO 00/27717 A1 discloses a device for opening a container is known, with a screw on a bottle neck ring collar, through which a tablet holder can be fixed on the bottle opening. By means of an actuating element pressure can be exerted on the tablet holder so that a side wall of the tablet holder facing the container contents breaks open and the tablet can be dispensed to the contents of the container. Subsequently, the ring collar can be unscrewed and the contents can be removed from the container. In order to avoid unintentional adding of the tablet, the actuating means is covered in the initial state inaccessible by a protective cap. In the initial state, the tablet is encapsulated in the tablet holder, in particular sealed liquid-tight.

Aus DE 69 22 863 U ist ein Verschluß bekannt, der zur Aufnahme eines Wirkstoffs einen zusätztlichen Behälter aufweist. Beim Öffnen des Verschlußes öffnet sich gleichzeitig der zusätztlichen Behälter, wobei der Wirkstoff ausgelöst wird.From DE 69 22 863 U a closure is known which has an additional container for receiving an active substance. When you open the shutter opens at the same time the additional container, the active ingredient is triggered.

Soweit die bekannten Vorrichtungen die Zugabe eines Wirkstoffs ermöglichen, ist deren Konstruktion und die Montage an dem Behälter aufwendig.As far as the known devices allow the addition of an active ingredient, the construction and assembly of the container is expensive.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Öffnen eines Behälters bereitzustellen, mit der auch ein Wirkstoff dem Inhalt des Behälters zugebbar ist, und die dennoch einfach und kostengünstig herstellbar und montierbar ist und darüber hinaus einfach und dauerhaft zuverlässig zu bedienen ist. Außerdem soll ein Verfahren zur Anordnung des Wirkstoffs an einer solchen Vorrichtung bereitgestellt werden.The invention has for its object to provide a device for opening a container with which an active ingredient is the content of the container zugebbar, and yet easy and inexpensive to manufacture and assemble and beyond easy and durable to use reliable. In addition, a method for the arrangement of the active substance is to be provided on such a device.

Diese Aufgabe ist durch die im Anspruch 1 bestimmten Vorrichtung sowie durch das im nebengeordneten Anspruch bestimmte Verfahren gelöst. Besondere Ausführungsarten der Erfindung sind in den Unteransprüchen bestimmt.This object is achieved by the device defined in claim 1 and by the method defined in the independent claim. Particular embodiments of the invention are defined in the subclaims.

Die Aufgabe ist bei einer Vorrichtung zum Öffnen eines Behälters, insbesondere eines Getränkebehälters, mit einem Betätigungselement, bei dessen Betätigen ein in fester Phase vorliegender Wirkstoff dem Inhalt des Behälters zugebbar ist, dadurch gelöst, dass der Wirkstoff an dem Betätigungselement und/oder einem weiteren Element der Vorrichtung festgefügt ist und dass beim erstmaligen Betätigen des Betätigungselements der Wirkstoff vom Betätigungselement und/oder dem weiteren Element lösbar ist und dadurch dem Inhalt des Behälters zugebbar ist.The object is in a device for opening a container, in particular a beverage container, with an actuating element, in the actuation of which a solid phase active substance can be added to the contents of the container, achieved in that the active ingredient in the Actuating element and / or a further element of the device is fixed and that upon actuation of the actuating element of the first time the active substance from the actuating element and / or the further element is detachable and thereby the content of the container is zugebbar.

Der Wirkstoff liegt ursprünglich granular oder pulverförmig vor. Das Festfügen erfolgt vorzugsweise durch Verpressen mit oder ohne Feuchtigkeitszugabe. Es entsteht dadurch eine kompakte Wirkstoffeinheit an der Vorrichtung, die beim Lösen vorzugsweise auch nicht wieder in den Ausgangszustand eines Granulats oder Pulvers zerfällt, sondern als kompakte Einheit oder jedenfalls nur in größeren Bruchstücken dem Inhalt des Behälters zugebbar ist. Das Zugeben kann ausschließlich aufgrund der Gewichtskraft erfolgen oder durch Unterstützung entsprechender Antreib- oder Schubmittelmittel der Vorrichtung. Nach dem Lösen des Wirkstoffs, gegebenenfalls nach nochmaligem Verschließen des Behälters, kann das Lösen des Wirkstoffs im Inhalt des Behälters durch Bewegung des Behälters beschleunigt werden.The active ingredient is originally granular or powdered. The staking is preferably carried out by pressing with or without addition of moisture. This results in a compact drug unit on the device, which preferably does not disintegrate when loosening again in the initial state of a granulate or powder, but as a compact unit or at least only in larger fragments the content of the container is zugebbar. The addition may be made solely on the basis of weight or by the assistance of appropriate means for propelling or pushing the device. After dissolution of the active ingredient, optionally after resealing the container, the dissolution of the active ingredient in the contents of the container can be accelerated by movement of the container.

Die erfindungsgemäße Vorrichtung kann sowohl an dem Behälter festgelegt werden, beispielsweise aufgeklebt werden, oder auf den Behälter lösbar aufgeschraubt werden. Insbesondere ist die Vorrichtung anwendbar für unter der Marke Tetra Pak angebotenen Getränkebehälter, wobei in diesem Fall die Vorrichtung vorzugsweise auf den komplett befüllten und verschlossenen Getränkebehälter aufgeklebt wird. In diesem Fall ist es vorteilhaft, dass beim erstmaligen Betätigen des Betätigungselements eine Öffnung in eine Außenwand des Behälters einbringbar ist. Hierzu kann die Vorrichtung ein weiteres Element aufweisen, das vorzugsweise einstückig ein Trennmittel ausbildet zum Öffnen des Behälters, insbesondere zum Durchtrennen einer hierfür vorgesehenen Stelle an der Außenwand des Behälters, die beispielsweise nur durch eine aluminiumbeschichtete Kunststoffolie gebildet sein kann. Über die so eingebrachte Öffnung kann der Wirkstoff dem Inhalt des Behälters zugebbar sein und/oder die eingebrachte Öffnung kann für die Entnahme des Inhalts aus dem Behälter dienen.The device according to the invention can both be fixed to the container, for example, be glued, or be detachably screwed onto the container. In particular, the device is applicable to beverage containers offered under the brand Tetra Pak, in which case the device is preferably adhered to the completely filled and sealed beverage container. In this case, it is advantageous that during the first actuation of the actuating element, an opening can be introduced into an outer wall of the container. For this purpose, the device may comprise a further element which preferably forms in one piece a separating means for opening the container, in particular for severing a location provided for this purpose on the outer wall of the container Container, which may be formed, for example, only by an aluminum-coated plastic film. About the thus introduced opening, the active ingredient may be attributed to the contents of the container and / or the introduced opening may serve for the removal of the contents of the container.

In einer besonderen Ausführungsart weist die Vorrichtung mindestens ein weiteres Element auf, wobei der Wirkstoff durch eine beim erstmaligen Betätigen des Betätigungselements auftretende Relativbewegung zwischen dem Betätigungselement und dem weiteren Element lösbar ist. Hierzu kann beispielsweise der Wirkstoff an einem Element festgefügt oder eingehakt sein und aufgrund der Relativbewegung gegen das andere Element stoßen bzw. die Verhakung gelöst werden und bei weiterer Relativbewegung vom ersten Element gelöst werden. Vorzugsweise bewegen sich beim Betätigen sowohl das Betätigungselement als auch das weitere Element, insbesondere kommt es zu einer gegensinnigen Drehbewegung dieser beiden Elemente.In a particular embodiment, the device has at least one further element, wherein the active substance can be released by a relative movement occurring between the actuating element and the further element when the actuating element is actuated for the first time. For this purpose, for example, the active ingredient may be fixed or hooked to an element and abut against the other element due to the relative movement or the entanglement can be released and released upon further relative movement of the first element. Preferably, both the actuating element and the further element move when actuated, in particular there is an opposite rotational movement of these two elements.

In einer besonderen Ausführungsart ist das Betätigungselement eine Kappe, insbesondere eine vom Behälter oder von einem weiteren Element der Vorrichtung, das an dem Behälter festlegbar ist, abschraubbare Schraubkappe. Damit kann der Behälter auch wieder verschließbar sein. Beim erstmaligen Abschrauben der Kappe kann das mit dem Trennmittel versehene weitere Element in Richtung auf die zu öffnende Außenwand des Behälters bewegt werden und letztlich die Öffnung in den Behälter einbringen.In a particular embodiment, the actuating element is a cap, in particular a screw cap unscrewable from the container or from a further element of the device which can be fixed to the container. Thus, the container can also be closed again. When unscrewing the cap for the first time, the further element provided with the separating agent can be moved in the direction of the outer wall of the container to be opened and ultimately bring the opening into the container.

Die Bewegungskopplung zwischen Betätigungselement und weiterem Element kann dabei nur beim erstmaligen öffnenden Betätigen bestehen und in Schließrichtung einen Freilauf aufweisen. Darüber hinaus kann die Kopplung auch beim erstmaligen Betätigen des Betätigungselements nur so weit vorgesehen sein, wie es für ein Öffnen des Behälters erforderlich ist. Ist der Behälter einmal geöffnet, kann die Bewegungskopplung zwischen Betätigungselement und weiterem Element gänzlich aufgehoben sein und das weitere Element kann in der die Außenwand des Behälters durchdringenden Position verbleiben, beispielsweise um eine definierte Öffnung des Behälters zu gewährleisten.The movement coupling between the actuating element and further element can only consist of the first opening operation and have a freewheel in the closing direction. In addition, the Coupling be provided only so far when you first press the actuator, as it is necessary for opening the container. Once the container has been opened, the movement coupling between the actuating element and the further element can be completely eliminated and the further element can remain in the position penetrating the outer wall of the container, for example to ensure a defined opening of the container.

In einer besonderen Ausführungsart weist das weitere Element Verhakungsmittel auf, in welche der festgefügte Wirkstoff eingehakt ist, der vorzugsweise gleichzeitig an dem Betätigungselement festgefügt oder jedenfalls ebenfalls verhakt ist. Kommt es nun zu einer Relativbewegung zwischen Betätigungselement und dem weiteren Element, wird eine Kraft auf die Festfüge- und/oder Verhakungsstelle zwischen dem Wirkstoff und dem Betätigungselement bzw. dem weiteren Element ausgeübt, die dann zu einem Lösen des festgefügten Wirkstoffs von der Vorrichtung führt.In a particular embodiment, the further element comprises interlocking means, in which the firmly attached active ingredient is hooked, which is preferably fixed at the same time to the actuating element or at least also hooked. If there is now a relative movement between the actuating element and the further element, a force is exerted on the fixation and / or hooking point between the active substance and the actuating element or the further element, which then leads to a release of the firmly attached active substance from the device.

Die Verhakungsmittel können auf verschiedenste Weise realisiert sein, beispielsweise durch eine geeignete regelmäßige oder unregelmäßige Oberflächenstruktur, durch Nuten, Öffnungen, Stege, Erhebungen usw., die eine Bewegungskopplung des eingehakten Wirkstoffes mit dem Element gewährleisten, so dass der Wirkstoff sich löst.The interlocking means can be realized in many different ways, for example by a suitable regular or irregular surface structure, by grooves, openings, webs, elevations, etc., which ensure a movement coupling of the hooked active substance with the element, so that the active ingredient dissolves.

In einer besonderen Ausführungsart ist der Wirkstoff verschlussmittelfrei an dem Betätigungselement und/oder dem weiteren Element der Vorrichtung festgefügt und eine Kapselung des Wirkstoffs gegenüber der Umgebung erfolgt erst durch das Anbringen der Vorrichtung an dem Behälter. Dadurch kann auf eine separate Verschlussmembran, wie sie im Stand der Technik erforderlich ist, verzichtet werden, wodurch sich einfachere und kostengünstigere Vorrichtungen und einfachere Montageverfahren ergeben.In a particular embodiment, the active ingredient is fastened to the actuating element and / or the further element of the device free of closure agent, and encapsulation of the active substance relative to the environment takes place only by attaching the device to the container. This allows for a separate sealing membrane, as in the prior art is required, be waived, resulting in simpler and less expensive devices and simpler assembly procedures.

In einer besonderen Ausführungsart handelt es sich bei dem Behälter um eine Weichverpackung für Flüssigkeiten, und durch den Wirkstoff wird dem Inhalt der Weichverpackung, insbesondere einem Getränk, beispielsweise Kohlensäure zugegeben. Dadurch ist es möglich, auch kohlensäurehaltige Getränke in einer Weichverpackung anzubieten. Im Falle eines wiederverschließbaren Behältnisses ist dafür Sorge zu tragen, dass eine ausreichende Entlüftung gewährleistet ist, beispielsweise durch eine entsprechende Ventilfunktion oder eine Entgasungsöffnung der erfindungsgemäßen Vorrichtung oder einer entsprechenden Einrichtung an dem Behälter. Die Vorrichtung kann aber auch bei anderen Behältern eingesetzt werden, insbesondere bei Kunststoff- oder Glasflaschen, Blechdosen, Kanistern, Fässern und dergleichen, vorzugsweise zum Aufbewahren und Transportieren von Lebensmitteln, insbesondere Getränken. Die Vorrichtung kann außerdem eine Sicherung gegen unbeabsichtigtes Betätigen des Betätigungselements aufweisen.In a particular embodiment, the container is a soft packaging for liquids, and by the active ingredient is added to the contents of the soft packaging, in particular a beverage, for example carbonic acid. This makes it possible to offer carbonated drinks in a soft packaging. In the case of a resealable container, care must be taken to ensure that sufficient ventilation is ensured, for example by means of a corresponding valve function or a degassing opening of the device according to the invention or a corresponding device on the container. The device can also be used in other containers, especially in plastic or glass bottles, tin cans, canisters, barrels and the like, preferably for storing and transporting food, especially drinks. The device may also have a safeguard against unintentional actuation of the actuating element.

Alternativ oder ergänzend kann es sich bei dem Wirkstoff auch um Nahrungsmittelergänzungsstoffe, Probiotika, Vitamine, Provitamine, Geschmacksstoffe, Hefe, Zucker oder dergleichen handeln oder um eine Mischung aus diesen Stoffen. So kann vorteilhaft eine Beimischung eines Trägerstoffes wie beispielsweise Zucker oder Traubenzucker verwendet werden, um die Festfügung des Wirkstoffes an der Vorrichtung zu vereinfachen.Alternatively or additionally, the active ingredient may also be food supplements, probiotics, vitamins, provitamins, flavorings, yeast, sugar or the like or a mixture of these substances. Thus, advantageously, an admixture of a carrier such as sugar or glucose can be used to facilitate the attachment of the active ingredient to the device.

Die Erfindung betrifft auch ein Verfahren zum Festfügen eines Wirkstoffes an einem Betätigungselement und/oder einem weiteren Element einer erfindungsgemäßen Vorrichtung zum Öffnen eines Behälters, insbesondere eines Getränkebehälters, wobei beim erstmaligen Betätigen des Betätigungselements der Behälter zu öffnen ist und der Wirkstoff vom Betätigungselement und/oder dem weiteren Element lösbar ist und in den Behälter einbringbar ist, und wobei der in fester Phase vorliegende, insbesondere granulare oder pulverförmige Wirkstoff an dem Betätigungselement und/oder dem weiteren Element festgefügt wird, insbesondere unter Einwirkung von Druck festgepresst wird. Beim Verpressen kann sich an der Oberfläche des festgefügten Wirkstoffes eine verhältnismäßig glatte, insbesondere feinporige oder geschlossene Oberfläche bilden, welche vorteilhaft die Oberfläche des Wirkstoffs verkleinert.The invention also relates to a method for fixing an active substance to an actuating element and / or a further element of a Device according to the invention for opening a container, in particular a beverage container, wherein upon first actuation of the actuating element, the container is to be opened and the active substance is detachable from the actuating element and / or the further element and can be introduced into the container, and wherein the solid phase, In particular, granular or powdery active substance is fixed to the actuating element and / or the further element, in particular is pressed under the action of pressure. During pressing, a relatively smooth, in particular fine-pored or closed surface can form on the surface of the firmly-attached active substance, which advantageously reduces the surface area of the active ingredient.

Alternativ zu einem Verpressen kann der Wirkstoff auch in Form einer entsprechend ausgebildeten Tablette vorliegen, die in einer Vormontage derart in die Vorrichtung eingelegt wird und vorzugsweise dort verhakt, dass die Tablette in einer Montageposition der Vorrichtung an dem Behälter, in der die Öffnung der Vorrichtung nach unten zeigt, in der Vorrichtung verbleibt.As an alternative to compression, the active ingredient may also be present in the form of a suitably formed tablet, which is inserted into the device in a pre-assembly and preferably hooked there, that the tablet in a mounting position of the device to the container in which the opening of the device below, remains in the device.

Abhängig von dem jeweiligen Wirkstoff und den Anwendungsbedingungen kann es vorteilhaft sein, dass der Wirkstoff vor und/oder während des Verpressens befeuchtet wird. Hierzu kann beispielsweise mittels einer Injektionsnadel eine vorgebbare Menge an Wasser in den festzufügenden Wirkstoff eingespritzt werden. Gegebenenfalls kann eine oder mehrere solcher Injektionsnadeln in den Druckstempel integriert werden. Alternativ oder ergänzend kann der Wirkstoff durch Wasserdampf, Sprühnebel oder dergleichen befeuchtet werden oder das Festfügen des Wirkstoffs kann in entsprechend feuchten Atmosphären erfolgen.Depending on the particular active ingredient and the conditions of use, it may be advantageous for the active ingredient to be moistened before and / or during the compression. For this purpose, for example, by means of an injection needle, a predeterminable amount of water can be injected into the solid substance to be solidified. Optionally, one or more such injection needles can be integrated into the plunger. Alternatively or additionally, the active ingredient can be moistened by steam, spray mist or the like or the fixing of the active ingredient can take place in correspondingly moist atmospheres.

In einer besonderen Ausführungsart wird der Wirkstoff in die komplett montierte, aus dem Betätigungselement und mindestens einem weiteren Element bestehende Vorrichtung eingepresst, die anschließend an dem Behälter festgelegt wird, insbesondere mittels einem Schraubflanschelement an dem Behälter festgeklebt wird. Auf diese Weise können vorteilhaft auch bestehende Öffnungsvorrichtungen durch die vorstehend beschriebene Festfügung des Wirkstoffes erfindungsgemäß ausgestaltet werden, so dass eine Neukonstruktion von Öffnungsvorrichtungen nicht unbedingt erforderlich ist. Das Festfügen des Wirkstoffes kann unmittelbar vor dem Festlegen der Vorrichtung an dem Behälter erfolgen; dadurch sind auch ohne eine separate Verschlussmembran die bei der Verpackung von Lebensmitteln zu stellenden hohen Hygieneanforderungen zu erfüllen.In a particular embodiment, the active substance is pressed into the completely assembled device consisting of the actuating element and at least one further element, which device is then fixed to the container, in particular by means of a Schraubflanschelement is glued to the container. In this way, advantageously existing opening devices can be designed according to the invention by the above-described attachment of the active ingredient, so that a redesign of opening devices is not absolutely necessary. The attachment of the active substance can take place immediately before fixing the device to the container; As a result, even without a separate sealing membrane to meet the packaging of food high hygiene requirements to be met.

Die Fig. 1 zeigt schematisch ein erstes Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung 1 zum Öffnen eines Behälters 2, insbesondere eines Getränkebehälters, mit einem Betätigungselement 3, bei dessen Betätigen ein in fester Phase vorliegender Wirkstoff 4 dem Inhalt 5 des Behälters 2 zugebbar ist. Bei dem Wirkstoff 4 kann es sich um Hydrogenkarbonat handeln, das beim Lösen im Behälters 2 Kohlensäure bildet. Bei dem Inhalt 5 kann es sich beispielsweise um einen Fruchtsaft oder einen Wein handeln, oder um eine Mischung aus Fruchtsaft oder Wein und Mineralwasser. Durch die Zugabe des Wirkstoffs 4 entsteht dann ein kohlensäurehaltiges Getränk. Bei dem Behälter 2 kann es sich insbesondere um eine Weichverpackung handeln, die im Ausgangszustand vollverschlossen und gefüllt ist und auf welche die Vorrichtung 1 mittels eines flanschartigen Befestigungselements 6 aufgeklebt ist, welches ein Außengewinde 7 aufweist, auf das ein kappenartiges Betätigungselement 3 aufschraubbar ist.Fig. 1 shows schematically a first embodiment of a device 1 according to the invention for opening a container 2, in particular a beverage container, with an actuating element 3, in the actuation of a present in solid phase active substance 4 to the contents 5 of the container 2 is zugebbar. The active ingredient 4 may be bicarbonate which forms carbonic acid when dissolved in the container 2. The content 5 may be, for example, a fruit juice or a wine, or a mixture of fruit juice or wine and mineral water. By adding the active ingredient 4 then creates a carbonated drink. The container 2 may in particular be a soft packaging, which is fully closed and filled in the initial state and to which the device 1 is glued by means of a flange-like fastening element 6, which has an external thread 7, on which a cap-like actuator 3 is screwed.

Die Fig. 2 zeigt in vergrößerter Darstellung einen Ausschnitt der Fig. 1 im Bereich der erfindungsgemäßen Vorrichtung 1. Das flanschartige Befestigungselement 6 kann beispielsweise mittels eines Heißschmelzklebers 31 an einer dafür vorgesehenen Stelle des Behälters 2 aufgeklebt werden, an welcher der Behälter 2 einen Bereich 8 aufweist, in dem die Außenwand 24 des Behälters 2 beispielsweise aufgrund einer reduzierten Materialstärke mit geringem Kraftaufwand durchtrennbar ist und eine Öffnung in den Behälter 2 eingebracht werden kann. An seinem im Wesentlichen ringförmig von dem Behälter 2 abstehenden Abschnitt 9 weist das Befestigungselement 6 ein vorzugsweise rechtsdrehendes Außengewinde 7 und auf der Innenseite ein vorzugsweise linksdrehendes Innengewinde 10 auf. Die Steigung des Innengewindes 10 ist dabei vorzugsweise größer als die Steigung des Außengewindes 7, beispielsweise um einen Faktor von 1,5 bis 3, insbesondere etwa 2.1 in the region of the device 1 according to the invention. The flange-like fastening element 6 can be glued, for example, by means of a hot-melt adhesive 31 to a designated location of the container 2, at which the container 2 a region 8 has, in which the outer wall 24 of the container 2, for example, due to a reduced material thickness with little effort is severable and an opening in the container 2 can be introduced. At its substantially annular projecting from the container 2 section 9, the fastening element 6 has a preferably right-handed external thread 7 and on the inside a preferably anti-clockwise internal thread 10. The pitch of the internal thread 10 is preferably greater than the pitch of the external thread 7, for example by a factor of 1.5 to 3, in particular about 2.

Das kappenartige Betätigungselement 3 weist ein mit dem Außengewinde 7 korrespondierendes Innengewinde 11 auf, mittels dem das Betätigungselement 3 auf das Befestigungselement 6 auf- und abschraubbar ist. An seiner Innenseite weist das Betätigungselement 3 außerdem einen vorzugsweise einstückig ausgebildeten Mitnahmefinger 12 auf, der beim öffnenden Betätigen entsprechend der Drehrichtung des Pfeils 13 mit einem vorzugsweise einstückig von einem weiteren Element 14 ausgebildeten Mitnahmeelement 15 zusammenwirkt und dadurch das weitere Element 14 in Drehrichtung gemäß dem Pfeil 16 bringt.The cap-like actuating element 3 has an internal thread 11 corresponding to the external thread 7, by means of which the actuating element 3 can be screwed up and down onto the fastening element 6. On its inner side, the actuating element 3 also has a preferably integrally formed driving finger 12, which cooperates with the opening direction corresponding to the direction of rotation of the arrow 13 with a preferably integrally formed by another element 14 driving element 15 and thereby the further element 14 in the direction of rotation according to the arrow 16 brings.

An der Vorrichtung ist der Wirkstoff 4 derart festgefügt, dass er in der in Fig. 2 dargestellten Montageposition der Vorrichtung 1 fixiert ist, insbesondere beim Zuführen an den Behälter 2 nicht aus der Vorrichtung 1 herausfällt. Hierzu kann der Wirkstoff 4 derart in die Vorrichtung 1 gepresst und/oder verhakt sein, gegebenenfalls unter Zuführung von Feuchtigkeit, dass der festgefügte Wirkstoff 4 an dem Betätigungselement 3 haftet. Alternativ oder ergänzend kann der Wirkstoff 4 auch mit als Öffnungen realisierte Verhakungselemente 17 des weiteren Elements 14 verhaken und dadurch in der dargestellten Position fixiert sein.The active substance 4 is firmly fixed to the device in such a way that it is fixed in the assembly position of the device 1 shown in FIG. 2, in particular does not fall out of the device 1 when it is supplied to the container 2. For this purpose, the active ingredient 4 may be pressed and / or hooked into the device 1, optionally with the introduction of moisture, so that the firmly attached active substance 4 adheres to the actuating element 3. Alternatively or additionally, the active substance 4 can also be hooked with interlocking elements 17 of the further element 14 realized as openings and thereby fixed in the illustrated position.

Das weitere Element 14 weist außerdem ein mit dem Innengewinde 10 des flanschartigen Befestigungselements 6 zusammenwirkendes Außengewinde 18 auf. Beim Drehen des Betätigungselements 3 gemäß Pfeil 13 kommt es aufgrund des Eingriffs des Außengewindes 7 des Befestigungselements 6 und des Innengewindes 11 zu einer öffnenden Bewegung des Betätigungselements 3 gemäß dem Pfeil 19. Aufgrund des demgegenüber gegenläufigen Innengewindes 10 des Befestigungselements 6, das mit dem Außengewinde 18 in Eingriff ist, kommt es gleichzeitig zu einer gekoppelten Dreh- und Längsbewegung des weiteren Elements 14 gemäß den Pfeilen 16, 20. Daraufhin durchtrennt das weitere Element 14 im Bereich 8 die Außenwand 24 des Behälters 2 und bringt in diesen eine Öffnung ein. Zu diesem Zweck kann das weitere Element 14 an seinem dem Behälter 2 zugewandten Ende Trennmittel 21 aufweisen, beispielsweise in Form von Spitzen oder Schneiden.The further element 14 also has an external thread 18 cooperating with the internal thread 10 of the flange-like fastening element 6. Upon rotation of the actuating element 3 according to arrow 13 due to the engagement of the external thread 7 of the fastening element 6 and the internal thread 11 there is an opening movement of the actuating element 3 according to the arrow 19. Due to the opposite counter-rotating internal thread 10 of the fastening element 6, with the external thread 18th is engaged, it comes simultaneously to a coupled rotational and longitudinal movement of the other element 14 according to the arrows 16, 20. Thereupon, the further element 14 cuts through the outer wall 24 of the container 2 in the region 8 and introduces into this an opening. For this purpose, the further element 14 may have at its end facing the container 2 separating means 21, for example in the form of tips or cutting.

Aufgrund der entgegengerichteten Längsbewegungen gemäß den Pfeilen 19, 20 und der unterschiedlichen Rotationsgeschwindigkeiten kommt es zu einer Relativbewegung zwischen dem Betätigungselement 3 und dem weiteren Element 14. Infolgedessen löst sich der festgefügte Wirkstoff 4 und kann aufgrund der Gewichtskraft in das Innere des Behälters 2 hineinfallen. Vorzugsweise ist die durch das weitere Element 14 in die Außenwand 24 eingebrachte Öffnung größer als die lichte Weite des weiteren Elements 14 in dem Bereich, in dem der Wirkstoff 4 in der Vorrichtung festgefügt ist.Due to the opposing longitudinal movements according to the arrows 19, 20 and the different rotational speeds, there is a relative movement between the actuating element 3 and the further element 14. As a result, the firmly bonded active substance 4 dissolves and can fall into the interior of the container 2 due to the weight force. Preferably, the opening introduced into the outer wall 24 by the further element 14 is greater than the inside width of the further element 14 in the region in which the active substance 4 is fixed in the device.

Für einige Anwendungen ist es wünschenswert, dass der Wirkstoff 4 beim Lösen von der Vorrichtung 1 in nicht allzu viele Bruchstücke zerfällt, insbesondere nicht pulverisiert wird. Sofern sich der Wirkstoff 4 einstückig von der Vorrichtung 1 löst oder jedenfalls nur in einigen größeren Bruchstücken, ist durch die sich dabei ergebende relativ geringe Oberfläche gewährleistet, dass sich der Wirkstoff 4 nicht zu schnell in dem Behälter 2 löst. Dies ist beispielsweise bei der Zugabe von Kohlensäure wünschenswert, da andernfalls die Gefahr einer übermäßigen Schaumbildung besteht. Für andere Anwendungen kann es wünschenswert sein, dass der Wirkstoff 4 beim Lösen in möglichst viele und möglichst kleine Bruchstücke zerfällt, um ein rasches Lösen und Vermischen zu gewährleisten.For some applications, it is desirable that the active ingredient 4 disintegrate when dissolving from the device 1 in not too many fragments, in particular not pulverized. Provided that the active substance 4 solves in one piece from the device 1 or at least only in some larger fragments, is characterized by the resulting relatively small surface area ensures that the active ingredient 4 does not dissolve too quickly in the container 2. This is desirable, for example, in the addition of carbonic acid, otherwise there is a risk of excessive foaming. For other applications, it may be desirable that the active ingredient 4 disintegrates when dissolved in as many and as small as possible fragments to ensure rapid dissolution and mixing.

Durch eine größere Steigung des Außengewindes 18 des weiteren Elements 14 gegenüber dem gegenläufigen Innengewinde 11 des Betätigungselements 3 ist sichergestellt, dass sich das weitere Element 14 um einen größeren Betrag in Richtung auf den Behälter 2 bewegt als sich das Betätigungselement 3 in entgegengesetzte Richtung bewegt. Zum einen wird dadurch ein Durchtrennen der Außenwand des Behälters 2 durch das weitere Element 14 sichergestellt. Zum anderen wird vermieden, dass nach einem erneuten Aufschrauben des Betätigungselements 3 dieses noch einmal in Eingriff mit dem weiteren Element 14 kommt. Insbesondere soll das weitere Element 14 nach dem erstmaligen Betätigen des Betätigungselements 3 in seiner den Behälter 2 öffnenden Position verbleiben und die eingebrachte Öffnung freihalten, sowohl für den Durchtritt des Wirkstoffs 4 in den Behälter 2 als auch für die Entnahme des Inhalts 5 aus dem Behälter 2. Eine Mitkopplung ergibt sich außerdem vorzugsweise nur bei einer Drehung des Betätigungselements 3 gemäß Pfeil 13. In umgekehrter Drehrichtung besteht ein Freilauf und insbesondere keine Bewegungskopplung zwischen dem Betätigungselement 3 und dem weiteren Element 14.By a larger pitch of the external thread 18 of the further element 14 relative to the counter-rotating internal thread 11 of the actuating element 3 ensures that the further element 14 moves by a larger amount in the direction of the container 2 as the actuator 3 moves in the opposite direction. On the one hand this ensures a severing of the outer wall of the container 2 by the further element 14. On the other hand, it is avoided that, after a renewed screwing on of the actuating element 3, this again comes into engagement with the further element 14. In particular, after the first actuation of the actuating element 3, the further element 14 should remain in its position opening the container 2 and keep the inserted opening clear, both for the passage of the active substance 4 into the container 2 and for the removal of the contents 5 from the container 2 A positive feedback also preferably results only in the case of a rotation of the actuating element 3 according to arrow 13. In the reverse direction of rotation there is a free-wheeling and in particular no movement coupling between the actuating element 3 and the further element 14.

Vorzugsweise wird beim erstmaligen Betätigen das weitere Element 14 beim Durchtrennen der Außenwand 24 des Behälters 2 um weniger als eine volle Umdrehung gedreht, bei Verwendung mehrerer in Umfangsrichtung in einem Winkelbereich von etwa 180° angeordneter Trennmittel 21 sogar um weniger als eine halbe Umdrehung gedreht, damit eine beim Durchtrennen der Außenwand 24 des Behälters 2 entstehende Verschlusshaut noch laschenartig an der Innenseite des Behälters 2 anhängt und nicht vollständig abgetrennt wird und in das Innere des Behälters 2 hineinfällt.Preferably, upon first actuation, the further element 14 will be less than when severing the outer wall 24 of the container 2 turned one full turn, even rotated by less than half a revolution when using a plurality of circumferentially arranged in an angular range of about 180 ° separating means 21, so that a resulting cut when severing the outer wall 24 of the container 2 still hangs plate-like on the inside of the container 2 and is not completely separated and falls into the interior of the container 2.

Die Außenwand 24 des Behälters 2 kann beispielsweise durch einen Verbund aus einem an der Außenseite gegebenenfalls noch mit einer Kunststofffolie kaschierten Karton 22 und einer zur Innenseite des Behälters 2 hin auf den Karton 22 aufgebrachten aluminiumbeschichteten Kunststofffolie 23 gebildet sein. Im Bereich 8, in dem durch das weitere Element 14 eine Öffnung in den Behälter einbringbar ist, besteht die Außenwand 24 lediglich aus der aluminiumbeschichteten Kunststofffolie 23.The outer wall 24 of the container 2 may be formed, for example, by a composite of a cardboard 22, optionally also laminated with a plastic film on the outside, and an aluminum-coated plastic film 23 applied to the inside of the container 2. In the region 8, in which an opening can be introduced into the container by the further element 14, the outer wall 24 consists only of the aluminum-coated plastic film 23.

Die Fig. 3 zeigt eine aus drei Elementen bestehende Schraubverschlusseinrichtung 125, die für ein zweites Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung verwendet werden kann. Das flanschartige Befestigungselement 106 kann an dem in der Fig. 3 nicht dargestellten Behälter 2 angeklebt werden. Der stutzenartig abstehende Abschnitt 109 weist ein Außengewinde 107 auf und ein Innengewinde 110 mit gegenüber dem Außengewinde 107 größerer Steigung. Auf das Außengewinde 107 ist das kappenartige Betätigungselement 103 aufschraubbar. In das Innengewinde 110 ist ein im Wesentlichen ringförmiges weiteres Element 114 einschraubbar, welches ein mit dem Innengewinde 110 des flanschartigen Betätigungselements 106 korrespondierendes Außengewinde 118 aufweist. An seinem dem Behälter 2 zugewandten stirnseitigen Ende bildet das weitere Element 114 in Umfangsrichtung über einen Winkelbereich von etwa 160° gleich verteilt insgesamt vier Trennmittel 121 aus, mit denen die Außenwand 24 des Behälters 2 durchtrennbar ist. Außerdem weist das weitere Element 114 auf seiner Mantelfläche mehrere Verhakungselemente 117 in Form von Öffnungen auf, in welche sich der an der Vorrichtung 1 festgefügte Wirkstoff 4 verhaken kann.Fig. 3 shows a three-element screw closure means 125 which can be used for a second embodiment of a device according to the invention. The flange-like fastening element 106 can be glued to the container 2, not shown in FIG. 3. The nozzle-like protruding portion 109 has an external thread 107 and an internal thread 110 with respect to the external thread 107 greater pitch. On the external thread 107, the cap-like actuator 103 is screwed. In the internal thread 110, a substantially annular further element 114 can be screwed, which has an external thread 118 corresponding to the internal thread 110 of the flange-like actuating element 106. At his the tank 2 facing end face forms the further element 114 in the circumferential direction over an angular range of about 160 ° evenly distributed a total of four release agent 121, with which the outer wall 24 of the container 2 can be severed. In addition, the further element 114 has on its lateral surface a plurality of hooking elements 117 in the form of openings into which the active substance 4 fixed to the device 1 can get caught.

Auf seiner Innenseite bildet das weitere Element 114 vorzugsweise einstückig und in Umfangsrichtung gleichverteilt insgesamt vier Mitnahmeelemente 115 aus, die mit entsprechend ausgebildeten Mitnahmefingern 112 korrespondieren, die vorzugsweise einstückig von dem Betätigungselement 103 ausgebildet werden. Beim Drehen des Betätigungselements 103 gemäß Pfeil 113 kommt es zu einer Abhebebewegung gemäß dem Pfeil 119 des Betätigungselements und gleichzeitig zu einer Eintauchbewegung gemäß dem Pfeil 120 des weiteren Elements 114. Die Mitnahmeelemente 115 und Mitnahmefinger 112 sind so ausgebildet, dass bei einer Schließbewegung entgegen der Drehrichtung gemäß Pfeil 113 keine Bewegungskopplung zwischen dem Betätigungselement 103 und dem weiteren Element 114 besteht.On its inside, the further element 114 forms preferably integrally and in the circumferential direction uniformly distributed a total of four driving elements 115, which correspond with correspondingly formed driving fingers 112, which are preferably formed in one piece by the actuating element 103. Upon rotation of the actuating element 103 according to arrow 113, there is a lift-off movement according to the arrow 119 of the actuating element and at the same time a plunge movement according to the arrow 120 of the further element 114. The entrainment elements 115 and driving finger 112 are formed so that in a closing movement counter to the direction of rotation According to arrow 113 there is no movement coupling between the actuating element 103 and the further element 114.

Die Fig. 4 zeigt nochmals die Elemente der Schraubverschlusseinrichtung 125 der Fig. 3, wobei diesmal eine Unteransicht des Betätigungselements 103 und des weiteren Elements 114 dargestellt ist, aus denen das Zusammenwirken der Mitnahmeelemente 115 und Mitnahmefinger 112 ersichtlich ist.FIG. 4 again shows the elements of the screw closure device 125 of FIG. 3, this time showing a bottom view of the actuating element 103 and the further element 114, from which the interaction of the entrainment elements 115 and driving finger 112 can be seen.

Die Fig. 5 bis 8 zeigen schematisch ein Ausführungsbeispiel für das erfindungsgemäße Verfahren zum Festfügen eines Wirkstoffes 4 an einem Betätigungselement 3 und/oder einem weiteren Element 14 einer Vorrichtung 1 zum Öffnen eines Behälters 2. Die Fig. 5 zeigt, wie in eine aus einem Betätigungselement 3, einem Befestigungselement 6 und einem weiteren Element 14 bestehende, komplett montierte Vorrichtung 1, deren offene Seite nach oben zeigt, mittels eines verschließbaren Trichters 26 der granular oder pulverförmig vorliegende Wirkstoff 4 in einer vorgebbaren Menge eingefüllt wird. Nach dem Befüllen ergibt sich der in der Fig. 6 gezeigte Zustand, in dem der Wirkstoff 4 als lose Schüttung in die Vorrichtung 1 eingefüllt ist. Wollte man in diesem Zustand die Vorrichtung 1 an einem Behälter 2 montieren, wäre es erforderlich, eine Verschlussmembran anzubringen, beispielsweise an dem flanschartigen Befestigungselement 6, um ein Herausfallen des Wirkstoffs 4 zu verhindern.5 to 8 show schematically an embodiment of the inventive method for fixing an active ingredient 4 to a Actuating element 3 and / or a further element 14 of a device 1 for opening a container 2. Fig. 5 shows, as in a consisting of an actuator 3, a fastener 6 and another element 14, completely assembled device 1, the open side pointing upward, by means of a closable funnel 26, the granular or powdered active substance 4 is introduced in a predeterminable amount. After filling, the state shown in FIG. 6 results, in which the active substance 4 is filled into the device 1 as a loose filling. If one wanted to mount the device 1 to a container 2 in this state, it would be necessary to attach a sealing membrane, for example to the flange-like fastening element 6, in order to prevent the active substance 4 from falling out.

Erfindungsgemäß erfolgt nun die in der Fig. 7 dargestellte Festfügung des Wirkstoffs 4 an dem Betätigungselement 3 und dem weiteren Element 14 unter Einwirkung von Druck mittels eines Druckstempels 27. Für manche Anwendungen kann es vorteilhaft sein, wenn über einen vorzugsweise zentrisch im Druckstempel 27 geführten Kanal 28 Feuchtigkeit, Wasser oder ein anderes geeignetes Lösungs- bzw. Verdichtungsmittel dem festzufügenden Wirkstoff 4 zugeführt wird, gegebenenfalls auch mittels einer an der Stirnseite des Druckstempels 27 überstehenden Injektionsnadel 29. Durch den Festfügevorgang, dessen Parameter wie beispielsweise Anpresskraft, Temperatur und Feuchtigkeit an den jeweiligen Anwendungsfall und insbesondere Wirkstoff 4 angepasst sind, ergibt sich der in der Fig. 8 dargestellte Zustand, in dem der Wirkstoff 4 an der Vorrichtung 1 festgefügt ist. Die Festfügung ergibt sich im Ausführungsbeispiels durch ein Anhaften des kompaktierten Wirkstoffs 4 an dem Betätigungselement 3 und/oder durch ein Verhaken des kompaktierten Wirkstoffs 4 mit dem weiteren Element 14. In diesem Zustand kann die Vorrichtung 1 so gedreht werden, dass die offene Seite nach unten zeigt, ohne dass der an der Vorrichtung 1 festgefügte Wirkstoff 4 herausfällt. In dieser Position kann die Vorrichtung 1 an dem Behälter 2 festgelegt werden, insbesondere aufgeklebt werden.According to the invention, the fusing of the active substance 4 to the actuating element 3 and the further element 14 under the action of pressure by means of a plunger 27 now takes place. For some applications, it may be advantageous to use a channel which is preferably guided centrally in the plunger 27 28 moisture, water or other suitable solvent or compression agent is supplied to the solidifying agent 4, optionally also by means of a protruding on the end face of the plunger 27 injection needle 29. By the Festfügevorgang whose parameters such as contact pressure, temperature and humidity to the respective Use case and in particular drug 4 are adjusted, resulting in the state shown in FIG. 8, in which the active ingredient 4 is fixed to the device 1. The Festfügung results in the embodiment by adhering the compacted drug 4 to the actuator 3 and / or by hooking the compacted drug 4 with the other element 14. In this state, the Device 1 are rotated so that the open side faces down, without the stuck to the device 1 active ingredient 4 falls out. In this position, the device 1 can be fixed to the container 2, in particular glued.

Die Fig. 9 zeigt schematisch das Öffnen des Behälters 2 mit einer erfindungsgemäßen Vorrichtung durch Drehen des Betätigungselements 3 entsprechend dem Pfeil 13, wobei es zu einer Abhebebewegung des Betätigungselements 3 entsprechend dem Pfeil 19 kommt. Gleichzeitig wird dadurch die Festfügung des Wirkstoffs 4 von der Vorrichtung 1 gelöst und der Wirkstoff 4 fällt im dargestellten Ausführungsbeispiel in Form von zwei größeren Bruchstücken 4a, 4b aufgrund der Gewichtskraft in den Behälter 2 entsprechend dem Pfeil 30. Anschließend kommt es zu einer Auflösung der Bruchstücke 4a, 4b im Behälter 2. Erforderlichenfalls kann durch Anbringen entsprechender Strukturen beispielsweise am Betätigungselement 3 vorgegeben sein, ob der gemäß Fig. 8 festgefügte Wirkstoff 4 in einem Stück, in wenigen großen Bruchstücken oder in vielen kleinen Bruchstücken von der Vorrichtung 1 gelöst wird.Fig. 9 shows schematically the opening of the container 2 with a device according to the invention by rotating the actuating element 3 according to the arrow 13, wherein there is a lifting movement of the actuating element 3 according to the arrow 19. At the same time thereby the fusing of the active ingredient 4 is released from the device 1 and the active ingredient 4 falls in the illustrated embodiment in the form of two larger fragments 4a, 4b due to the weight in the container 2 according to the arrow 30. Then there is a dissolution of the fragments 4a, 4b in the container 2. If necessary, can be predetermined by attaching appropriate structures, for example on the actuator 3, whether the fixed according to FIG. 8 active ingredient 4 in one piece, in a few large fragments or in many small fragments of the device 1 is released.
