Der Erfindung liegt insbesondere die Aufgabe zugrunde, eine kostengünstige und einfache Austragvorrichtung für eine Mehrkomponentenmasse bereitzustellen. Sie wird durch eine erfindungsgemäße Austragvorrichtung entsprechend dem Anspruch 1 gelöst. Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.The invention is in particular the object of providing a cost-effective and simple discharge device for a multi-component mass. It is achieved by a discharge device according to the invention according to claim 1. Further developments of the invention will become apparent from the dependent claims.
Die Erfindung geht aus von einer Austragvorrichtung zum gleichzeitigen Ausbringen von zumindest zwei fließfähigen Komponenten einer Mehrkomponentenmasse aus unterschiedlichen Vorratsvolumen, mit einer passiven Mischeinheit, die einen zentralen Mischkanal aufweist, der zur Führung der miteinander vermengten Komponenten sich entlang einer Fließrichtung erstreckt, und mit zumindest zwei Zuflüssen, die in den zentralen Mischkanal münden.The invention is based on a discharge device for the simultaneous discharge of at least two flowable components of a multicomponent mass from different storage volumes, with a passive mixing unit having a central mixing channel which extends along a flow direction for guiding the components mixed together, and with at least two inlets , which flow into the central mixing channel.
Es wird vorgeschlagen, dass die Zuflüsse dem gleichen Vorratsvolumen zugeordnet sind und entlang der Fließrichtung an unterschiedlichen Stellen in den Mischkanal münden. Dadurch kann erreicht werden, dass sich die einzelnen Komponenten in dem zentralen Mischkanal miteinander vermengen, ohne dass in dem Mischkanal ein zusätzliches Mischelement angeordnet werden muss, welches für eine Vermischung der einzelnen Komponenten miteinander vorgesehen ist. Durch eine erfindungsgemäße Ausgestaltung kann somit auf ein zusätzliches Mischelement in dem zentralen Mischkanal verzichtet werden, wodurch die Austragvorrichtung besonders kostengünstig ausgebildet werden kann. Unter einer Mehrkomponentenmasse soll insbesondere eine fließfähige Masse aus zumindest zwei Komponenten verstanden werden, wobei zumindest eine der Komponenten ein Aktivator ist, durch den nach einem Vermischen der Komponenten eine chemische Reaktion ausgelöst wird, durch welche sich chemische oder physikalische Eigenschaften der Mehrkomponentenmasse verändern. Unter einer "Komponente der Mehrkomponentenmasse" soll dabei insbesondere ein fließfähiges Material verstanden werden, welches unvermischt mit einer anderen Komponente über einen Zeitraum gelagert werden kann, der länger ist als ein Zeitraum, während dem nach dem Vermischen der Komponenten die chemische Reaktion abläuft. Vorzugsweise sind die voneinander getrennten Komponenten über eine Zeitraum von Wochen, Monaten oder Jahren lagerbar, während die Mehrkomponentenmasse nach dem Vermischen der Komponenten innerhalb eines Zeitraums von Sekunden, Minuten oder Stunden ihre endgültigen Eigenschaften annimmt. Unter einer "passiven Mischeinheit" soll insbesondere eine Mischeinheit verstanden werden, die zum Vermischen der einzelnen Komponenten lediglich ortsfest angeordnete Komponenten aufweist und bei der eine Bewegung der Komponenten durch die Mischeinheit eine Vermengung der Komponenten miteinander bewirkt. Unter einem "Zufluss" soll in diesem Zusammenhang insbesondere ein in den zentralen Mischkanal mündender Kanal verstanden werden, der zur Führung von lediglich einer der Komponenten, d.h. nicht zur Führung der vermengten Mehrkomponentenmasse, vorgesehen ist. Unter einem "zentralen Mischkanal" soll in diesem Zusammenhang insbesondere ein Kanal verstanden werden, der zur Führung der miteinander vermengten Komponenten vorgesehen ist. Unter einer "Fließrichtung" soll insbesondere eine Richtung verstanden werden, entlang der die Komponenten, insbesondere nachdem sie miteinander vermengt wurden, fließen, wenn sie aus der Austragvorrichtung ausgebracht werden. Die Fließrichtung wird insbesondere durch eine Erstreckungsrichtung der Zuflüsse und/oder des zentralen Mischkanals vorgegeben und kann grundsätzlich von einer geradlinigen Richtung abweichen, beispielsweise wenn der zentrale Mischkanal für eine bessere Handhabung abgeknickt ist oder wenn er wellenförmig ausgeführt ist. Unter "vorgesehen" soll insbesondere speziell ausgelegt und/oder ausgestattet verstanden werden.It is proposed that the inflows are assigned to the same storage volume and open along the flow direction at different points in the mixing channel. It can thus be achieved that the individual components in the central mixing channel mix with one another without an additional mixing element having to be arranged in the mixing channel for mixing the individual components together. By an embodiment of the invention can thus be dispensed with an additional mixing element in the central mixing channel, whereby the discharge can be designed particularly inexpensive. A multicomponent composition is to be understood as meaning, in particular, a flowable mass of at least two components, wherein at least one of the components is an activator, by means of which a chemical reaction is triggered after mixing of the components, by which chemical or physical properties of the multicomponent mass change. A "component of the multicomponent composition" should be understood to mean, in particular, a flowable material which can be stored unmixed with another component over a period of time which is longer than a period during which the chemical reaction takes place after the components have been mixed. Preferably, the discrete components are storable over a period of weeks, months or years, while the multicomponent mass assumes its final properties after mixing the components within a time period of seconds, minutes or hours. A "passive mixing unit" should in particular be understood to mean a mixing unit which has only stationary components for mixing the individual components and in which a movement of the components through the mixing unit causes mixing of the components with one another. In this context, an "inflow" is to be understood as meaning, in particular, a channel opening into the central mixing channel and intended to guide only one of the components, ie not to guide the mixed multicomponent mass. Under a "central A "flow direction" is to be understood in particular as meaning a direction along which the components, in particular after they have been mixed with one another, flow when they pass through The flow direction is predetermined in particular by an extension direction of the inflows and / or the central mixing channel and may in principle deviate from a rectilinear direction, for example if the central mixing channel is bent for better handling or if it is wave-shaped "intended" should be understood in particular specially designed and / or equipped.
Indem die Zuflüsse, die an unterschiedlichen Stellen in den zentralen Mischkanal münden, dem gleichen Vorratsvolumen zugeordnet sind, kann erreicht werden, dass die jeweilige Komponente an unterschiedlichen Stellen der bereits im Mischkanal vorhandenen Mehrkomponentenmasse zugemischt wird, wodurch eine besonders gute Vermischung der Komponenten erreicht werden kann.By the inflows, which open at different points in the central mixing channel, are assigned to the same storage volume, it can be achieved that the respective component is mixed at different points of existing already in the mixing channel multi-component mass, whereby a particularly good mixing of the components can be achieved ,
Weist weiter die Mischeinheit zumindest einen weiteren Zufluss auf, der in den Mischkanal mündet, können beide Komponenten an einer der Stellen zusammengeführt werden, wodurch die Vermischung der Komponenten weiter verbessert werden kann, ohne dass ein zusätzliches Mischelement notwendig ist. Oder es kann eine der Komponenten an einer weiteren Stelle der bereits vermischen Mehrkomponentenmasse zugeführt werden, wodurch ebenfalls die Vermischung verbessert werden kann.Further, if the mixing unit has at least one further inflow, which opens into the mixing channel, both components can be brought together at one of the points, whereby the mixing of the components can be further improved without the need for an additional mixing element. Or it can be fed to one of the components at a further point of the already mixed multicomponent mass, whereby also the mixing can be improved.
Ferner wird vorgeschlagen, dass die Mischeinheit zumindest einen direkt an eines der Vorratsvolumen angebundenen Zuführkanal aufweist, der sich zumindest einmal in zumindest zwei der Zuflüsse verzweigt. Dadurch kann die Austragvorrichtung konstruktiv besonders einfach ausgestaltet werden. Unter einem "Zuführkanal" soll in diesem Zusammenhang insbesondere ein Kanal zur Führung von genau einer Komponente der Mehrkomponentenmasse verstanden werden, über den die Komponente aus dem entsprechenden Vorratsvolumen auf die dem Vorratsvolumen zugeordneten Zuflüsse verteilt wird. Vorzugsweise weist die Austragvorrichtung eine gleiche Anzahl von Zuführkanälen und Vorratsvolumen auf.It is also proposed that the mixing unit has at least one supply channel directly connected to one of the storage volumes, which branches at least once into at least two of the feeds. As a result, the discharge device can be made structurally particularly simple. In this context, a "supply channel" is to be understood as meaning, in particular, a channel for guiding precisely one component of the multicomponent mass, via which the component from the corresponding storage volume to the storage volume allocated inflows is distributed. Preferably, the discharge device has an equal number of supply channels and storage volume.
In einer vorteilhaften Weiterbildung der Erfindung wird vorgeschlagen, dass der zumindest eine Zuführkanal und der zentrale Mischkanal zumindest im Wesentlichen parallel verlaufen. Dadurch kann die Austragvorrichtung mittels einfacher Formteile hergestellt werden, wodurch eine besonders einfache und damit kostengünstige Massenproduktion möglich ist.In an advantageous development of the invention, it is proposed that the at least one feed channel and the central mixing channel run at least substantially parallel. As a result, the discharge device can be produced by means of simple molded parts, whereby a particularly simple and thus cost-effective mass production is possible.
Vorzugsweise münden die zumindest zwei Zuflüsse von unterschiedlichen Seiten in den zentralen Mischkanal. Dadurch kann eine besonders gute Vermischung der Komponenten erreicht werden. Unter "von unterschiedlichen Seiten" soll dabei insbesondere verstanden werden, dass die Zuflüsse bezüglich einer Ebene, in der der zentrale Mischkanal liegt, von unterschiedlichen Seiten in den Mischkanal münden.Preferably, the at least two tributaries open from different sides into the central mixing channel. As a result, a particularly good mixing of the components can be achieved. The term "from different sides" is to be understood in particular as meaning that the inlets open into the mixing channel from different sides with respect to a plane in which the central mixing channel lies.
Besonders vorteilhaft münden die einem der Vorratsvolumen zugeordneten Zuflüsse jeweils wechselweise von den Seiten in den zentralen Mischkanal. Dadurch kann eine besonders gute Durchmischung erreicht werden. Unter "wechselweise" soll in diesem Zusammenhang insbesondere verstanden werden, dass entlang der Fließrichtung die Zuflüsse, die dem gleichen Vorratsvolumen zugeordnet sind, die Seiten wechseln, von denen die Zuflüsse in den zentralen Mischkanal münden.Particularly advantageously, the flows assigned to one of the supply volumes each lead alternately from the sides into the central mixing channel. This allows a particularly good mixing can be achieved. By "alternately" is to be understood in this context, in particular, that along the flow direction, the inflows, which are assigned to the same storage volume, change sides, from which the tributaries open into the central mixing channel.
Weiter wird vorgeschlagen, dass die Austragvorrichtung eine Packungsfolie umfasst, die einen Teil der Zuflüsse ausbildet. Durch eine solche Ausgestaltung können die Zuflüsse besonders einfach realisiert werden. Unter einer "Folie" im Allgemeinen soll dabei insbesondere ein Metall- oder Kunststoffblatt mit einer Dicke von höchstens 1 Millimeter verstanden werden. Vorzugsweise beträgt die Dicke der Folie höchstens 500 Mikrometer. Besonders vorteilhaft hat die Folie eine Dicke von höchstens 100 Mikrometer. Unter einer "Packungsfolie" im Speziellen soll insbesondere eine Folie verstanden werden, die eine von einer ebenen Erstreckung abweichende Form aufweist, durch die sie die Zuflüsse ausbildet, wie insbesondere eine mittels einer Form umgeformte Kunststofffolie.It is further proposed that the discharge device comprises a packing film which forms part of the inflows. By such an embodiment, the tributaries can be particularly easily realized. A "foil" in general should be understood to mean in particular a metal or plastic sheet having a thickness of at most 1 millimeter. Preferably, the thickness of the film is at most 500 microns. Particularly advantageously, the film has a thickness of at most 100 micrometers. In particular, a film is intended to mean a "packaging film" in particular be understood, which has a deviating from a flat extent form through which it forms the tributaries, in particular a deformed by means of a mold plastic film.
Bildet die Packungsfolie weiter die Vorratsvolumen und den zumindest einen Zuführkanal zumindest teilweise aus, kann die Austragvorrichtung konstruktiv besonders einfach ausgestaltet werden. Insbesondere ist eine Ausgestaltung der Austragvorrichtung mit einer geringen Anzahl von Teilen möglich, wodurch zudem eine besonders kostengünstige Herstellung realisiert werden kann.If the packing film further forms at least part of the storage volume and the at least one supply channel, the discharge device can be made structurally particularly simple. In particular, an embodiment of the discharge with a small number of parts is possible, which also allows a particularly cost-effective production can be realized.
Außerdem wird vorgeschlagen, dass die Packungsfolie den zentralen Mischkanal zumindest teilweise ausbildet. Dadurch kann die konstruktive Ausgestaltung weiter vereinfacht werden. Vorzugsweise werden die Zuflüsse, die Vorratsvolumen, der zumindest eine Zuführkanal und der Mischkanal in einem Umformschritt aus einem Folienrohling hergestellt.It is also proposed that the packing film at least partially form the central mixing channel. As a result, the structural design can be further simplified. Preferably, the inflows, the storage volume, the at least one feed channel and the mixing channel are produced in a forming step from a film blank.
Vorzugsweise bildet die Packungsfolie den zentralen Mischkanal zumindest teilweise aus. Dadurch kann die konstruktive Ausgestaltung der Austragvorrichtung weiter vereinfacht werden. Vorzugsweise werden die Zuflüsse, die Vorratsvolumen, der zumindest eine Zuführkanal und der Mischkanal in einem Umformschritt aus einem Folienrohling hergestellt.Preferably, the packing film at least partially forms the central mixing channel. As a result, the structural design of the discharge device can be further simplified. Preferably, the inflows, the storage volume, the at least one feed channel and the mixing channel are produced in a forming step from a film blank.
Ferner wird vorgeschlagen, dass die Austragvorrichtung eine Coverfolie aufweist, die einen Teil der Zuflüsse zumindest teilweise ausbildet. Dadurch kann eine erfindungsgemäße Austragvorrichtung besonders einfach hergestellt werden, insbesondere wenn die Zuflüsse von unterschiedlichen Seiten in den Mischkanal münden sollen.It is also proposed that the discharge device has a cover film which forms part of the inflows at least partially. As a result, a discharge device according to the invention can be produced in a particularly simple manner, in particular if the inflows from different sides are to flow into the mixing channel.
Vorteilhafterweise umfasst die Austragvorrichtung weiter eine zwischen der Packungsfolie und der Coverfolie angeordnete Siegelfolie. Dadurch können insbesondere die Zuflüsse, die teilweise von der Packungsfolie und teilweise von der Coverfolie ausgebildet werden, einfach voneinander getrennt werden. Durch eine solche Ausgestaltung ist die Austragvorrichtung als ein Blister ausbildbar, welcher von der Packungsfolie, der Coverfolie und der Siegelfolie gebildet wird. Die Packungsfolie, die Coverfolie und die Siegelfolie können dabei in einem Schweißverfahren miteinander verbunden werden, wodurch eine einfache und kostengünstige Ausgestaltung realisiert werden kann.Advantageously, the discharge device further comprises a sealing film arranged between the packaging film and the cover film. As a result, in particular the inflows, which are partially formed by the packaging film and partially by the cover film, can be easily separated from one another. By such an embodiment, the discharge device can be formed as a blister, which is formed by the packaging film, the cover film and the sealing film. The packaging film, the cover film and the sealing film can are connected together in a welding process, whereby a simple and inexpensive design can be realized.
Begrenzt die Siegelfolie zumindest den zentralen Mischkanal, den zumindest einen Zuführkanal und zumindest einen Teil der Zuflüsse, kann eine Anzahl der für die Ausgestaltung der Austragvorrichtung erforderlichen Bauteile gering gehalten werden. Insbesondere ist dadurch eine dreiteilige Ausgestaltung denkbar.If the sealing film at least delimits the central mixing channel, the at least one feed channel and at least part of the inflows, a number of the components required for the configuration of the discharge device can be kept small. In particular, by a three-part design is conceivable.
In einer besonders vorteilhaften Ausgestaltung weist die Siegelfolie zumindest eine Perforation auf, die den zumindest einen durch die Coverfolie ausgebildeten Zufluss mit dem durch die Packungsfolie ausgebildeten Zuführkanal verbindet. Dadurch können die durch die Coverfolie ausgebildeten Zuflüsse einfach mit dem Zuführkanal verbunden werden, wodurch die Zuflüsse insgesamt in zwei unterschiedlichen Ebenen angeordnet werden können, die durch die Siegelfolie voneinander getrennt sind.In a particularly advantageous embodiment, the sealing film has at least one perforation, which connects the at least one inflow formed by the cover film with the feed channel formed by the packing film. Thereby, the inflows formed by the cover sheet can be easily connected to the feed channel, whereby the inflows can be arranged in total in two different levels, which are separated by the sealing film.
Zudem ist vorteilhaft, wenn die Siegelfolie zumindest eine Perforation aufweist, die den zumindest einen durch die Coverfolie ausgebildeten Zufluss mit dem durch die Packungsfolie ausgebildeten zentralen Mischkanal verbindet. Dadurch kann insbesonders einfach realisiert werden, dass die Zuflüsse von unterschiedlichen Seiten in den zentralen Mischkanal münden, wodurch eine besonders einfache konstruktive Ausgestaltung möglich ist.In addition, it is advantageous if the sealing film has at least one perforation, which connects the at least one inflow formed by the cover film with the central mixing channel formed by the packing film. This makes it particularly easy to realize that the tributaries open from different sides in the central mixing channel, whereby a particularly simple structural design is possible.
Außerdem wird vorgeschlagen, dass die Austragvorrichtung zumindest einen Aktivierungspin aufweist, der dazu vorgesehen ist, bei einer Aktivierung zumindest eine der Perforationen zu erzeugen. Dadurch können die Komponenten in einem Auslieferungszustand durch die Siegelfolie voneinander getrennt werden, wodurch eine vorzeitige Vermischung mit hoher Sicherheit vermieden werden kann. Gleichzeitig kann die Austragvorrichtung einfach aktiviert werden, beispielsweise indem die Mischeinheit komprimiert wird, wodurch eine einfache Handhabung der Austragvorrichtung realisiert werden kann.In addition, it is proposed that the discharge device has at least one activation pin which is provided to generate at least one of the perforations upon activation. As a result, the components can be separated from one another in a delivery state by the sealing film, whereby premature mixing with high security can be avoided. At the same time, the discharge can be easily activated, for example by the Mixing unit is compressed, whereby a simple handling of the discharge can be realized.

Die Austragvorrichtung umfasst in dem dargestellten Ausführungsbeispiel zwei Vorratskammern, die die Vorratsvolumen 10, 11 begrenzen. Die Vorratsvolumen 10, 11 sind nebeneinander angeordnet. Durch eine Komprimierung der Vorratskammern, beispielsweise indem der Blister 26 mittels des Clips 27 aufgerollt wird, werden die einzelnen Komponenten aus den Vorratsvolumen 10, 11 hinausgedrückt. Um die Komponenten miteinander zu vermischen, weist die Austragvorrichtung eine passive Mischeinheit 12 auf, in der die Komponenten allein durch ihre Bewegung durch die Mischeinheit 12 hindurch miteinander zu der gebrauchsfertigen Mehrkomponentenmasse vermengt werden.The discharge device comprises in the illustrated embodiment, two storage chambers, which limit the

Zur Ausbildung der Vorratsvolumen 10, 11, der Zuführkanäle 19, 20, der Zuflüsse 15, 16, 17, 18 und des Mischkanals 13 weisen die Packungsfolie 21 und die Coverfolie 22 jeweils eine Höhenprofilierung auf, die durch Umformung eines Rohlings mittels entsprechender Formen ausgebildet wird. In Bezug auf die Ebene, in der die Siegelfolie 23 angeordnet ist, bilden die Höhenprofilierung der Packungsfolie 21 und die Höhenprofilierung der Coverfolie 22 Vertiefungen aus. Ist die Siegelfolie 23 mit der Packungsfolie 21 und der Coverfolie 22 verbunden, bilden diese Vertiefungen Hohlkammern aus, welche die Vorratsvolumen 10, 11, die Zuführkanäle 19, 20, die Zuflüsse 15, 16, 17, 18 und den Mischkanal 13 ausbilden.
