Attached to the top of at least the first container (1, 2) is a tubular adapter (5, 6) which surrounds the valve (3, 4) on the first container and is designed as a guide element to enable the top of the second container (2, 1) to be set on the first and displaced axially.

Description

"Vorrichtung zum Verbinden zweier jeweils im Kopfbereich mit Sprühventil aus¬ gerüsteten Behälter" "Device for connecting two containers each equipped with a spray valve in the head area"
Die Erfindung betrifft eine Vorrichtung zum Verbinden zweier jeweils im Kopf¬ bereich mit Sprühventil ausgerüsteten Behälter zum Einfüllen des Inhalts eines Behälters in den anderen Behälter.The invention relates to a device for connecting two containers, each equipped with a spray valve in the head region, for filling the contents of one container into the other container.
Es sind nachfüllbare Gasfeuerzeuge bekannt, welche mit unter Überdruck stehendem Gas gefüllt sind und auf der dem Kopfbereich, der die Austrittsöffnung mit Zündmechanismus aufweist, gegenüberliegenden Unterseite eine Nachfüllöffnung mit Rückschlagventil aufweisen. Durch diese Nachfüllöffnung ist es möglich, Brenngas nachzufüllen, wobei dieses Brenngas üblicherweise in einer unter Druck stehenden Aerosoldose mit Sprühventil aufbewahrt wird. Diese Aerosoldose wird zum Nachfüllen mit ihrem Sprühventil oder einer rohrförmigen Verlängerung gegen die Unterseite des nachfüllbaren Feuerzeuges gedrückt, so daß die Sprühventilöffnung bzw. die rohrförmige Verlängerung unter Öffnung des Rückschlagventils in die Nachfüllöffnung eindringt, durch diese Drückbewegung gleichzeitig das Sprühventil betätigt wird und Brenngas aus der Aerosoldose in das Feuerzeug eintritt. Nach dem Füljvorgang werden beide Elemente wieder voneinander getrennt, und durch das Rückschlagventil am Feuerzeug wird ein Austreten des Brenngases durch die Nachfüllöffnung zuverlässig vermieden.Refillable gas lighters are known which are filled with gas under excess pressure and have a refill opening with a non-return valve on the underside opposite the head region which has the outlet opening with ignition mechanism. This refill opening makes it possible to refill fuel gas, this fuel gas usually being stored in a pressurized aerosol can with a spray valve. This aerosol can is pressed for refilling with its spray valve or a tubular extension against the underside of the refillable lighter, so that the spray valve opening or the tubular extension penetrates into the refill opening while opening the check valve, the spray valve is simultaneously actuated by this pushing movement and fuel gas from the Aerosol can enters the lighter. After the filling process, both elements are separated from each other again, and the check valve on the lighter reliably prevents the fuel gas from escaping through the refill opening.
Es ist auch bekannt, zum Ausschäumen von Hohlräumen oder dgl. Schäume auf der Basis von Polyurethan einzusetzen, die in Aerosoldosen abgefüllt sind. Diese Schäume können dann durch einfaches Versprühen aus der Aerosoldose ent¬ weder direkt aus dem Sprühventil oder über eine rohrförmige bzw. schlauch- förmige Verlängerung in einen Hohlraum oder dgl. eingebracht werden.It is also known to use foams based on polyurethane for filling cavities or the like, which are filled in aerosol cans. These foams can then be introduced by spraying from the aerosol can either directly from the spray valve or via a tubular or tubular extension into a cavity or the like.
Es sind auch zweikomponentige Polyurethan-Schäume bekannt, die erst unmittelbar vor der Anwendung miteinander vermischt werden dürfen. D.h. beide Komponenten müssen in verschiedenen Behältern aufbewahrt werden. Auch diese zweikomponentigen Produkte lassen sich auf einfache Weise mittels einer Sprühdose mit Sprühventil versprühen, so daß man eine Komponente in einer derartigen Sprühdose aufbewahren könnte und die andere Komponente in einem anderen Behälter, dessen unter Überdruck stehender Inhalt dann allerdings vor der Anwendung in die die andere Komponente enthaltende Sprühdose einge¬ bracht werden muß. Hier könnte in ähnlicher Weise vorgegangen werden wie beim Prinzip des nachfüllbaren Feuerzeuges. Dies würde es jedoch erforderlich machen, eine herkömmliche, auf einfache Weise herzustellende Sprühdose vor¬ zugsweise auf der Unterseite zusätzlich noch mit einer Einfüllöffnung mit ent¬ sprechender Abdichtung (Rückschlagventil) oder dgl. auszurüsten, was einen zu¬ sätzlichen Herstellungs- und Montageaufwand nach sich ziehen würde.Two-component polyurethane foams are also known, which may only be mixed with one another immediately before use. Ie both components must be kept in different containers. Also these two-component products can be sprayed in a simple manner by means of a spray can with a spray valve, so that one component could be stored in such a spray can and the other component in another container, the contents of which are under pressure, however, before being used in the other component containing spray can must be introduced. This could be done in a similar way to the refillable lighter principle. However, this would make it necessary to additionally equip a conventional spray can, which is simple to produce, preferably on the underside, with a filler opening with a corresponding seal (check valve) or the like, which entails additional manufacturing and assembly costs would pull.
Aufgabe der Erfindung ist es deshalb, auf einfache und leicht handhabbare Weise ein in einem Behälter befindliches unter Druck stehendes Produkt in einen mit Sprühventil ausgerüsteten Behälter mit ebenfalls unter Druck stehendem Inhalt einzufüllen.The object of the invention is therefore to fill a product under pressure in a container into a container equipped with a spray valve with contents that are also under pressure in a simple and easy-to-use manner.
Diese Aufgabe wird mit einer Vorrichtung der eingangs bezeichneten Art erfin¬ dungsgemäß durch wenigstens ein am ersten Behälter im Kopfbereich befestig¬ bares erstes rohrförmiges Adapterteil gelöst, welches das Sprühventil des ersten Behälters umgibt und als Führungselement zum Aufsetzen und axialen Ver¬ schieben des Kopfbereiches des zweiten Behälter ausgebildet ist.This object is achieved with a device of the type described in the introduction by at least one first tubular adapter part which can be fastened to the first container in the head region and which surrounds the spray valve of the first container and as a guide element for fitting and axially displacing the head region of the second Container is formed.
Auf diese Weise ist es möglich, beide Komponenten des wenigstens zwei¬ komponentigen Produktes in herkömmliche Aerosoldosen und dgl. getrennt ab¬ zufüllen, ohne daß diese Aerosoldosen zusätzliche Füllöffnungen oder dgl. auf¬ weisen müssen. Durch Aufsetzen des wenigstens einen Adapterteils auf einen der beiden Behälter wird es dann auf einfache Weise ermöglicht, den anderen Behäl¬ ter gezielt und geführt derart Kopfbereich an Kopfbereich aufzusetzen, daß beide Behälter axial gegeneinander derart zusammengeschoben werden können, daß beide Sprühventile in die Betätigungsposition niedergedrückt werden und folglich das zuzumischende Produkt, das sich in einem der Behälter unter einem höheren Druck abgefüllt befindet, in den anderen Behälter einfüllbar ist. Ersichtlich können somit zwei herkömmliche Sprühflaschen verwendet werden, die keinerlei Zusatzelemeπte aufweisen müssen. Es ist lediglich eine erfindungsgemäßen Vor- richtung erforderlich, die vorzugsweise auch mehrfach verwendet werden kann, da sie kein integraler Bestandteil des Behälters ist.In this way it is possible to fill both components of the at least two-component product separately into conventional aerosol cans and the like, without these aerosol cans having to have additional filling openings or the like. By placing the at least one adapter part on one of the two containers, it is then possible in a simple manner to place the other container in a targeted and guided manner in such a way that the head region to the head region is such that both containers can be pushed together axially in such a way that both spray valves are pressed down into the actuating position are and consequently the product to be mixed, which is filled in one of the containers under a higher pressure, can be filled into the other container. Obviously, two conventional spray bottles can be used that do not have to have any additional elements. It is only a pre-invention direction required, which can preferably be used several times, since it is not an integral part of the container.
In besonders vorteilhafter Ausgestaltung ist vorgesehen, daß die Vorrichtung ein am zweiten Behälter im Kopfbereich befestigbares zweites rohrförmiges Adapter¬ teil aufweist, welches axial verschiebbar gegenüber dem ersten Adapterteil aus¬ gebildet ist. Auf diese Weise läßt sich eine noch bessere Führung der beiden zu¬ sammenzuführenden bzw. gegeneinander zu drückenden Behälter erreichen, gleichzeitig läßt sich auch die Abdichtung der Verbindungsbereiche der beiden Sprühventile durch diese Ausgestaltung verbessern, so daß zuverlässig gewähr¬ leistet ist, daß Produkt nur vom einen Behälter in den anderen Behälter eintritt und nicht an die Umgebung abgegeben wird.In a particularly advantageous embodiment it is provided that the device has a second tubular adapter part which can be fastened to the second container in the head region and which is designed to be axially displaceable relative to the first adapter part. In this way, an even better guidance of the two containers to be brought together or pressed against one another can be achieved, at the same time the sealing of the connection areas of the two spray valves can also be improved by this configuration, so that it is reliably ensured that product only from one container enters the other container and is not released into the environment.
Besonders vorteilhaft ist vorgesehen, daß die beiden Adapterteile ineinander schraubbar ausgebildet sind. Auf diese Weise ist eine besonders gute Führung und gezielte axiale Zusammenfügung und somit gezielte Betätigung der beiden Sprühventile zum Zusammenführen der Produkte möglich. Grundsätzlich können hier aber auch andere dem Fachmann geläufige Gestaltungen zur Verschiebung verwendet werden.It is particularly advantageously provided that the two adapter parts are designed to be screwed into one another. In this way, particularly good guidance and targeted axial assembly and thus targeted actuation of the two spray valves for bringing the products together is possible. In principle, however, other designs known to those skilled in the art can also be used for the displacement.
Weiterhin ist vorteilhaft vorgesehen, daß ein Adapterteil innenliegend eine Hülse aufweist, welche das Sprühventil des zugehörigen Behälters umgibt und eine axiale Einführung des Sprühventils des anderen Behälters ermöglicht. Auf diese Weise ist der Verbindungsbereich beider Behälter, nämlich der Bereich des Zu¬ sammentreffens beider Sprühventile, gegenüber der Umgebung noch besser ab¬ gedichtet.Furthermore, it is advantageously provided that an adapter part has a sleeve on the inside, which surrounds the spray valve of the associated container and enables an axial introduction of the spray valve of the other container. In this way, the connection area between the two containers, namely the area where the two spray valves meet, is sealed even better from the surroundings.
Dabei ist ganz besonders bevorzugt vorgesehen, daß in der Hülse axial ver¬ schiebbar geführt eine Ringdichtung angeordnet ist, deren Öffnungsdurchmesser kleiner als der Außendurchmesser der Sprühventile ist. Durch diese Gestaltung läßt sich eine ganz besonders gute Abdichtung erreichen, wobei durch die axiale Verschiebbarkeit der Ringdichtung gewährleistet ist, daß sich deren Position flexibel an den jeweiligen Verbindungsort der beiden Sprühventile anpassen kann und sich nicht verkantet, so daß die Abdichtung nicht beeinträchtigt wird. Dabei ist es zweckmäßig, daß die Hülse an der dem zugeordneten Sprühventil gegenüberliegenden Ende einen umlaufenden Endanschlag für die Ringdichtung aufweist, damit die Ringdichtung nicht aus der Hülse herausfallen kann. Diese ist am anderen Ende durch das zugeordneten Sprühventil bei auf dem zugeordneten Behälter aufgesetzten Adapterteil gehalten.It is very particularly preferably provided that an annular seal is arranged in the sleeve so as to be axially displaceable, the opening diameter of which is smaller than the outside diameter of the spray valves. This design enables a particularly good seal to be achieved, the axial displacement of the ring seal ensuring that its position can adapt flexibly to the respective connection location of the two spray valves and does not become jammed, so that the seal is not impaired. It is expedient for the sleeve to have a circumferential end stop for the ring seal at the end opposite the associated spray valve so that the ring seal cannot fall out of the sleeve. This is held at the other end by the assigned spray valve when the adapter part is placed on the assigned container.
Vorteilhaft sind im Falle von zwei Adapterteilen Anschlagflächen zum Begrenzen der axialen Verschiebbarkeit der beiden Adapterteile gegeneinander. Die aufeinanderliegenden Anschlagflächen ermöglichen dem Anwender, einen vorgegebenen, definierten Druck auf die Sprühveπtile auszuüben.In the case of two adapter parts, stop surfaces for limiting the axial displaceability of the two adapter parts against one another are advantageous. The superimposed abutment surfaces enable the user to exert a predetermined, defined pressure on the spray valves.
Die Erfindung ist nachstehend anhand der Zeichnung beispielsweise näher erläu¬ tert. Diese zeigt in:The invention is explained in more detail below with reference to the drawing, for example. This shows in:

Fig. 3 eine abgewandelte Ausführungsform einer erfindungsgemäßen Vor¬ richtung.3 shows a modified embodiment of a device according to the invention.
In der Zeichnung ist ein nicht vollständig dargestellter erster Behälter mit 1 be¬ zeichnet und ein zweiter Behälter mit 2. Bei beiden Behältern handelt es sich vor¬ zugsweise um Aerosoldosen, welche im Kopfbereich jeweils mit einem ersten bzw. zweiten Sprühventil 3, 4 ausgerüstet sind.In the drawing, a first container (not shown completely) is designated 1 and a second container is designated 2. Both containers are preferably aerosol cans, each of which is equipped with a first or second spray valve 3, 4 in the head region .
Diese Ventile 3, 4 lassen sich in bekannter Weise durch Niederdrücken in Rich¬ tung des Behälterinneren betätigen, derart, daß dann durch rohrförmigen Ventile 3, 4 Produkt aus dem Behälter 1 bzw. 2 austreten kann, welches sich jeweils unter Überdruck stehend im Behälter 1 bzw. 2 befindet. Da beim dargestellten Ausführungsbeispiel Produkt aus dem kleineren Behälter 2 in den größeren Behälter 1 eingefüllt werden soll, herrscht im Behälter 2 gegen¬ über dem mit einem anderen Produkt gefüllten Behälter 1 ein größerer Druck.These valves 3, 4 can be actuated in a known manner by pressing down in the direction of the interior of the container, in such a way that tubular valves 3, 4 can then release product from the container 1 or 2, which is under pressure in the container 1 or 2. Since, in the exemplary embodiment shown, product from the smaller container 2 is to be filled into the larger container 1, there is a greater pressure in the container 2 compared to the container 1 filled with another product.
Um nun auf einfache Weise das Produkt aus dem Behälter 2 in den Behälter 1 einfüllen zu können, ist eine erfindungsgemäße Vorrichtung vorgesehen, die beim gezeigten Ausführungsbeispiel ein erstes rohrförmiges Adapterteil 5 und ein zweites rohrförmiges Adapterteil 6 aufweist.In order to be able to fill the product from the container 2 into the container 1 in a simple manner, a device according to the invention is provided which, in the exemplary embodiment shown, has a first tubular adapter part 5 and a second tubular adapter part 6.
Das erste Adapterteil 5 ist am ersten Behälter 1 im Kopfbereich desselben befestigbar, wozu der Behälter 1 vorzugsweise einen Bördelwulst 7 aufweist, auf den das erste Adapterteil 5 mit einem umlaufenden, innenliegenden Befesti¬ gungswulst 8 aufgeprellt ist. Darüber hinaus kann das erste Adapterteil 5 auch noch eine umlaufende Schulter 9 aufweisen, welche sich an der Behälteroberseite abstützt.The first adapter part 5 can be fastened to the first container 1 in the head region thereof, for which purpose the container 1 preferably has a flanged bead 7, onto which the first adapter part 5 is bounced with a circumferential, inner fastening bead 8. In addition, the first adapter part 5 can also have a circumferential shoulder 9, which is supported on the top of the container.
Ausgehend vom Befestigungswulst 8 erstreckt sich das erste Adapterteil 5 zu¬ nächst im wesentlichen axial, dieser Bereich ist mit 10 bezeichnet. Dieser Bereich 10 geht an seinem anderen Ende in einen radialen Bereich 11 über, welcher in einen inneren hülsenförmigen Bereich 12 mündet, der bereichsweise das Sprüh¬ ventil 3 des Behälters 1 umgibt und sich innerhalb des Bördelwulstes 7 bis in den Fußbereich desselben erstreckt und an diesem anliegt. Innenseitig ist dabei der hülsenförmige Bereich 12 des Adapterteils 5 als Innengewinde 13 ausgebildet.Starting from the fastening bead 8, the first adapter part 5 initially extends essentially axially; this region is designated by 10. This area 10 merges at its other end into a radial area 11, which opens into an inner sleeve-shaped area 12, which partially surrounds the spray valve 3 of the container 1 and extends within the bead 7 to the foot area thereof and on it is present. On the inside, the sleeve-shaped area 12 of the adapter part 5 is designed as an internal thread 13.
Aύßenseitig ist der axiale Bereich 10 im Übergang zum radialen Bereich 11 mit einer umlaufenden Anlageschulter 14 versehen, welche zur Aufnahme eines Originalitätsverschlusses 15 dient, der hülsenförmig oder verschlußkappenförmig ausgebildet sein kann und zum öffnen bevorzugt mit einer Perforation 16 ver¬ sehen ist. An diesen Originalitätsverschluß 15 ist radial nach außen vorstehend ein Sicherungsring 17 angeformt, dessen Funktion nachfolgend noch erläutert wird.On the outside, the axial region 10 is provided in the transition to the radial region 11 with a circumferential contact shoulder 14, which serves to receive a tamper-evident closure 15, which can be sleeve-shaped or cap-shaped and is preferably provided with a perforation 16 for opening. At this tamper-evident closure 15, a locking ring 17 is formed radially outward, the function of which will be explained below.
Der zweite Behälter 2 weist zur Befestigung des zugeordneten zweiten Adapter¬ teils 6 und zur Befestigung des Ventils 4 einen Bördelwulst 18 auf, auf dem das Adapterteil 6 mit einem äußeren rohrförmigen Bereich 19 aufgeprellt ist, welcher dazu endseitig einen umlaufenden Befestigungswulst 20 aufweist. Der äußere rohrförmige Bereich 19 geht am anderen Ende in ein radialen, nach innen gerich¬ teten Bereich 21 über, wobei außenseitig im Übergangsbereich am rohrförmigen Bereich 19 eine umlaufende Anschlagschulter 22 vorgesehen ist.The second container 2 has a flanged bead 18 for fastening the assigned second adapter part 6 and for fastening the valve 4, on which the adapter part 6 is bounced with an outer tubular region 19 which to this end has a circumferential fastening bead 20. The outer tubular region 19 merges at the other end into a radial, inwardly directed region 21, a circumferential stop shoulder 22 being provided on the outside in the transition region on the tubular region 19.
Dieser radiale Bereich 21 geht innenseitig zunächst in einen hülsenförmigen Bereich 23 über, welcher endseitig am Bördelwulst 18 des Behälters 2 anliegt und sich bis in den Fußbereich desselben erstreckt. Entgegengesetzt zu diesem Bereich 23 geht der radiale Bereich 21 des Adapterteils 6 darüber hinaus in einen rohrförmigen Bereich 24 über, der außenseitig als Außengewinde 25 ausgebildet ist, wobei das Außengewinde 25 derart dimensioniert ist, daß dieses in das Innengewinde 13 des anderen Adapterteils 5 einschraubbar ist. Darüber hinaus ist an dem Innenrandbereich des radialen Bereiches 21 des Adapterteils 6 eine Hülse 26 angeformt, welche sich innerhalb des hülsenförmigen Bereiches 23 er¬ streckt und bereichsweise das Ventil 4 des Behälters 2 umgibt. Innerhalb dieser Hülse 26 ist axial verschiebbar geführt eine Ringdichtung 27, deren axiale Ver¬ schiebbarkeit einerseits durch das freie Ende des Ventils 4 und andererseits durch einen ringförmigen Anschlag 28 innerhalb der Hülse 26 begrenzt ist. Dabei ist der Innendurchmesser des Anschlages 28 der Hülse 26 so dimensioniert, daß er kleiner ist, als der Außendurchmesser der Ringdichtung 27 aber wenigstens geringfügig größer als der Außendurchmesser des Endes des Ventils 3 des ersten Behälters 1 , derart, daß das Ventil 3 durch den Anschlagring 28 hindurch in das Innere der Hülse 26 in Richtung zum anderen Ventil 4 hin eindringen kann.This radial area 21 initially merges into a sleeve-shaped area 23, which abuts the flanged bead 18 of the container 2 at the end and extends into the foot area thereof. Contrary to this area 23, the radial area 21 of the adapter part 6 also merges into a tubular area 24, which is formed on the outside as an external thread 25, the external thread 25 being dimensioned such that it can be screwed into the internal thread 13 of the other adapter part 5 . In addition, a sleeve 26 is formed on the inner edge area of the radial area 21 of the adapter part 6, which sleeve extends within the sleeve-shaped area 23 and partially surrounds the valve 4 of the container 2. An annular seal 27 is guided axially displaceably within this sleeve 26, the axial displaceability of which is limited on the one hand by the free end of the valve 4 and on the other hand by an annular stop 28 inside the sleeve 26. The inner diameter of the stop 28 of the sleeve 26 is dimensioned so that it is smaller than the outer diameter of the ring seal 27 but at least slightly larger than the outer diameter of the end of the valve 3 of the first container 1, such that the valve 3 through the stop ring 28 can penetrate into the interior of the sleeve 26 in the direction of the other valve 4.
Vorzugsweise werden die Behälter 1 und 2 getrennt voneinander angeboten, wo¬ bei jeweils das eine bzw. andere Adapterteil 5, 6 auf den jeweiligen Behälter 1 , 2 aufgesetzt ist. Grundsätzlich können die Behälter 1 , 2 auch ohne Adapterteil ver¬ trieben werden, und die Adapterteile 5, 6 können als Einzelteile vertrieben werden, welche der Anwender dann auf den jeweiligen Behälter 1 , 2 aufsetzen muß.The containers 1 and 2 are preferably offered separately from one another, with one or the other adapter part 5, 6 being placed on the respective container 1, 2. Basically, the containers 1, 2 can also be sold without an adapter part, and the adapter parts 5, 6 can be sold as individual parts, which the user must then place on the respective container 1, 2.
Um nun den Inhalt des Behälters 2 in den Behälter 1 zu entleeren, werden zu¬ nächst beide Behälter 1 , 2 mit den aufgesetzten Adapterteilen 5, 6 in der in Figur 1 dargestellten Weise aufeinandergesetzt, wozu zunächst der Originalitätsver¬ schluß 15 am Adapterteil 5 durch Abreißen entlang der Perforation 16 entfernt wird. Der Behälter 2 mit seinem Adapterteil 6 wird dann mit seinem Außen¬ gewinde 25 in das Innengewinde 13 des ersten Adapterteils 5 des ersten Behäl¬ ters 1 eingeschraubt (beispielsweise 1 1/2 Umdrehungen). Bei der dadurch ent¬ stehenden axialen Bewegung der beiden Adapterteile 5, 6 bzw. der beiden Behäl¬ ter 1 , 2 zueinander wird die Ringdichtung 27, deren innere Öffnung 27a selbst¬ verständlich einen kleineren Durchmesser als der Außendurchmesser der Ventil¬ schäfte 4 bzw. 3 aufweist, zwischen den Ventilschäften 3 und 4 eingeklemmt und dichtet somit zwischen beiden Ventilen. Beim weiteren Einschrauben des zweiten Adapterteils 6 in das erste Adapterteil 5 und dem weiteren axialen Aufeinander¬ treffen der Ventile 3, 4 und der Ringdichtung 27 beginnt das Öffnen der Ventile 3, 4. Durch unterschiedliche Ventilgeometrien, Ventilwege und Drücke entsteht da¬ bei eine Undefinierte Lage der Ringdichtung 27. Um hier eine flexible Anpassung zu erreichen, ist deshalb die Ringdichtung 27 in der Hülse 26 in axialer Richtung verschiebbar geführt. Durch das Niederdrücken beider Ventile 3, 4 (Fig. 2) tritt nun Produkt aus dem Behälter 2 in den Behälter 1 ein. Ein definierter Druck auf die beiden Ventile wird durch die Lage der radialen Bereiche 11 , 21 gewährleistet, die Anschlagflächen zum Begrenzen des Ineinanderschraubens bilden. Treffen beide Bereiche 11, 21 aufeinander, so ist der gewünschte Druck auf die Ventile erreicht.In order to empty the contents of the container 2 into the container 1, both containers 1, 2 with the attached adapter parts 5, 6 are first placed on top of one another in the manner shown in FIG. 1, for which purpose the tamper-evident closure 15 on the adapter part 5 first Tear off along perforation 16 becomes. The container 2 with its adapter part 6 is then screwed with its external thread 25 into the internal thread 13 of the first adapter part 5 of the first container 1 (for example 1 1/2 turns). During the resulting axial movement of the two adapter parts 5, 6 or the two containers 1, 2 relative to one another, the ring seal 27, the inner opening 27a of which is of course a smaller diameter than the outer diameter of the valve stems 4 or 3 has, clamped between the valve stems 3 and 4 and thus seals between the two valves. When the second adapter part 6 is screwed further into the first adapter part 5 and the valves 3, 4 and the ring seal 27 collide further axially, the valves 3, 4 begin to open. Different valve geometries, valve paths and pressures result in an undefined Position of the ring seal 27. In order to achieve a flexible adaptation here, the ring seal 27 is therefore guided in the sleeve 26 so as to be displaceable in the axial direction. By depressing both valves 3, 4 (FIG. 2), product from container 2 now enters container 1. A defined pressure on the two valves is ensured by the position of the radial regions 11, 21, which form stop surfaces to limit screwing into one another. If both areas 11, 21 meet, the desired pressure on the valves is reached.
Nach einer vorgegebenen Injektionszeit, die von den in den Behältern 1 bzw. 2 befindlichen Produkten, den Druckverhältnissen und den Größenverhältnissen abhängt, wird der Behälter 2 mit seinem Adapterteil 6 abgeschraubt. Im Behälter 1 steht dann das zusammengemischte zweikomponentige Produkt zur Verfügung, welches dann nach einer geringen Wartezeit und nach Schütteln (zur besseren Durchmischung) verwendet werden kann. Dazu wird dann vorzugsweise, wie an sich bekannt, am Sicherungsring 17 ein Betätigungshebel mit Rohr abgetrennt und der Hebel auf das Ventil 3 aufgeschraubt. Dies ist im einzelnen nicht dargestellt.After a predetermined injection time, which depends on the products in the containers 1 and 2, the pressure conditions and the size relationships, the container 2 is unscrewed with its adapter part 6. The mixed two-component product is then available in container 1, which can then be used after a short waiting time and after shaking (for better mixing). For this purpose, as is known per se, an actuating lever with a tube is preferably cut off on the securing ring 17 and the lever is screwed onto the valve 3. This is not shown in detail.
In Figur 3 ist eine weitere Ausführungsform einer erfindungsgemäßen Vorrichtung dargestellt, wobei dort allerdings nur der Behälter 2 und nicht der Behälter 1 gezeigt ist. Bei dieser Ausführungsform ist das Adapterteil 5 für den nicht darge¬ stellten Behälter 1 im Prinzip in gleicher Weise wie beim Ausführungsbeispiel nach Figuren 1 und 2 ausgestaltet, lediglich das Adapterteil 6 weist eine etwas andere Gestaltung auf. Dieses weist nämlich im rohrförmigen Bereich 19 nicht nur einen Befestigungswulst 20 auf, sondern zwei Befestigungswülste 20a, welche in entsprechend vorgesehene Befestigungswülste 29 am patronenförmigen Behälter 2 einprellbar sind. Dementsprechend entfällt bei diesem Adapterteil 6 der innere rohrförmige Bereich 23. Der patronenförmige Behälter 2 weist dabei selbstver¬ ständlich wiederum ein nicht dargestelltes Ventil auf, welches von der Hülse 26 bereichsweise umschlossen ist. Ansonsten ist die Funktionsweise dieser Vorrich¬ tung die gleiche wie bei der beschriebenen Vorrichtung.A further embodiment of a device according to the invention is shown in FIG. 3, although only the container 2 and not the container 1 is shown there. In this embodiment, the adapter part 5 for the container 1 (not shown) is designed in principle in the same way as in the exemplary embodiment according to FIGS. 1 and 2, only the adapter part 6 has something different design on. This is because, in the tubular region 19, it not only has a fastening bead 20, but also two fastening beads 20a, which can be pushed into correspondingly provided fastening beads 29 on the cartridge-shaped container 2. Accordingly, the inner tubular region 23 is omitted in this adapter part 6. The cartridge-shaped container 2 naturally has a valve, not shown, which is enclosed by the sleeve 26 in some areas. Otherwise, the functioning of this device is the same as that of the device described.
Natürlich ist die Erfindung nicht auf die dargestellten Ausführungsbeispiele beschränkt. Weitere Ausgestaltungen der Erfindung sind möglich, ohne den Grundgedanken zu verlassen. So kann beispielsweise das Adapterteil 5 bei entsprechender Dimensionierung auch mit dem Behälter 2 und folglich das Adapterteil 6 auch mit dem Behälter 1 verbunden werden. Of course, the invention is not limited to the exemplary embodiments shown. Further refinements of the invention are possible without leaving the basic idea. For example, the adapter part 5 can also be connected to the container 2, and consequently the adapter part 6 can also be connected to the container 1, if the dimensions are appropriate.
