Abstract

Dual component container systems are provided for separately storing at least two liquids, which are intermixed within the system prior to dispensing. Two or more containers having mixing openings are provided wherein the mixing openings are sealed by sealing members. The sealed openings of the containers are interconnected by one or more connecting elements, thereby forming a sealed conduit interposed between containers and wherein at least one of the sealing members is connected to the connecting element by a releasable clamping joint. Systems of the present invention are designed such that relative movement of the two containers causes the sealing members to open or be removed, whereby fluids from the two or more containers may intermix via the open conduit formed by the connecting element.

Description

Die Erfindung bezieht sich auf ein Behältersystem aus mindestens zwei Behältern zur getrennten Aufbewahrung von Stoffen, die in gemischtem Zustand zu verwenden sind, wobei die Behälter jeweils eine mittels einer Verschlusskappe abschliessbare Mischöffnung aufweisen und mittels eines mit den Verschlusskappen zusammenwirkenden Verbindungsstücks mit einander zugewandten Mischöffnungen miteinander verbunden sind.The invention relates to a container system comprising at least two containers for separate storage of substances to be used in a mixed state are, the containers each being lockable by means of a closure cap Have mixing opening and by means of one with the caps cooperating connector with mutually facing mixing openings are interconnected.

Beispielsweise ist ein Doppelkammersystem bekannt, in denen Zweikomponenten-Substanzen getrennt verschlossen aufbewahrt sind. Vor Gebrauch müssen die Behälterverschlüsse durch Zerstörung, beispielsweise durch Aufschneiden oder Durchstossen, geöffnet werden, um die Subtanzen zusammen zu bringen. Aus der Patentschrift DE-C-44 36 863 ist ein solches Doppelkammersystem bekannt, bei welchem die Behälter durch festklemmbare Stopfen verschlossen sind, die durch eine Relativ-Bewegung zu einander sich gegenseitig aus der Klemmverschlusslage herausdrücken und dadurch Verbindungskanäle zwischen den Behältern freigeben. Dadurch sind jedoch die Behälteröffnungen sehr weit eingeengt und werden die zu vermischenden Substanzen an den Konstruktionsteilen zwischen den Behältern bzw. deren Öffnungen gehindert werden und teilweise daran haften.For example, a double-chamber system is known in which two-component substances are kept separately locked. Before use the container closures by destruction, for example by cutting or poking through, to bring the substances together. Such a double-chamber system is known from patent specification DE-C-44 36 863, in which the containers are closed by clampable plugs, which move relative to each other from the clamp position push out and thereby connecting channels between the containers release. As a result, however, the container openings are very narrowed and the substances to be mixed on the construction parts between the containers or their openings are hindered and partially be liable.

Es ist ferner ein derartiges Behältersystem in der nicht offenbarten deutschen Patentanmeldung 19635833 derselben Erfinder der vorliegenden Erfindung beschrieben.It is also such a container system in the not disclosed German Patent application 19635833 of the same inventor of the present invention.

Das dort beschriebene Behältersystem, das dazu dient, ein aus zwei Komponenten bestehendes Haarfärbemittel aufzubewahren, besteht aus einem zylinderförmigen unteren Behälter und einem kugelförmigen oberen Behälter. Der untere Behälter weist an der Oberseite und der obere Behälter an der Unterseite jeweils eine Mischöffnung auf. Beide Mischöffnungen sind mittels einer Schraubkappe abgeschlossen, wobei die Schraubkappe des unteren Behälters in den Hals dieses Behälters eingeschraubt ist, während die Schraubkappe des oberen Behälters in ein Gewindeteil eines Verbindungsrings geschraubt ist. Der obere Behälter ist in ein Aussengewindeteil des Verbindungsrings geschraubt, so dass die Öffnung des oberen Behälters letztendlich sowohl durch die jeweilige Verschlusskappe als auch durch den Verbindungsring abgeschlossen wird. Der untere Behälter samt darauf festgeschraubter Kappe ist mit dem Hals in das Innengewindeteil des Verbindungsrings geschraubt. Beim Ineinanderschrauben der verschiedenen Behälter, der jeweiligen Kappen und des Verbindungsrings wird zwischen beiden Kappen ausserdem eine Schnappverbindung hergestellt.The container system described there, which serves one of two components Retaining existing hair dye consists of a cylindrical one lower container and a spherical upper container. The lower Container faces on the top and the top container on the bottom, respectively a mixing opening. Both mixing openings are by means of a screw cap completed, with the screw cap of the lower container in the neck of this Container is screwed in while the screw cap of the upper container is screwed into a threaded part of a connecting ring. The upper container is in screwed an external thread part of the connecting ring so that the opening of the upper container ultimately through both the respective cap is also completed by the connecting ring. The lower container together screwed cap is with the neck in the internal thread part of the connecting ring screwed. When screwing the different containers together, the respective caps and the connecting ring is between the two caps also creates a snap connection.

Bevor sie ineinandergeschraubt wurden, sind beide Behälter im übrigen mit den unterschiedlichen Komponenten des Haarfärbemittels abgefüllt worden. Alle Schraubverbindungen ausser der Gewindeverbindung zur Befestigung der Verschlusskappe im unteren Behälter sind gleichgängig. Ausserdem weisen beide Schraubkappen ineinandergreifende Zapfen auf, und die Schraubkappe des unteren Behälters hat einen in radialer Richtung vorspringenden Teil, der mit einer im Verbindungsring befindlichen, axial orientierten Führungsbahn zusammenwirken kann.Before they were screwed into each other, both containers are with the rest different components of the hair dye have been filled. All Screw connections apart from the threaded connection for fastening the sealing cap in the lower container are the same. In addition, both point Screw caps interlocking pegs, and the screw cap of the bottom Container has a projecting part in the radial direction, which with a in Interacting axially oriented guideway can.

Wenn jetzt die Flüssigkeiten in beiden Behältern zum Gebrauch vermischt werden sollen, wird zunächst ein Teil des Zwischenrings, der beispielsweise als Abrissstreifen ausgeführt werden kann, entfernt, um eine gegenseitige axiale Bewegung beider Behälter zu ermöglichen. Anschliessend wird der untere Behälter gegenüber dem Verbindungsring und dem oberen Behälter gedreht, wobei sich seine Kappe durch das gegenläufige Gewinde der Kappe ebenfalls drehen wird. Die Zapfen dieser Schraubkappe und die Zapfen der Kappe des oberen Behälters greifen dabei ineinander, so dass auch diese Kappe sich dreht und sich so aus dem Verbindungsring löst.Now if the liquids are mixed in both containers for use should first be a part of the intermediate ring, for example as a tear strip can be performed away from each other for axial movement to enable both containers. The lower container is then opposite the connecting ring and the upper container rotated, with its The cap will also turn due to the opposite thread of the cap. The Pin of this screw cap and the pin of the cap of the upper container interlock so that this cap also rotates and turns out releases the connecting ring.

Beim Drehen werden die vorspringenden Teile der Schraubkappe des unteren Behälters und die Führungsbahn des Verbindungsrings irgendwann ineinandergreifen, so dass die Schraubkappe gegen Weiterdrehen gesichert wird. Wenn der untere Behälter gegenüber dem Zwischenring weitergedreht wird, wird seine Schraubkappe jetzt festgehalten und durch das gegenläufige Gewinde der Kappe aus dem Hals des unteren Behälters gelöst. Auf diese Weise werden letztendlich die Schraubkappe des unteren Behälters und die damit verbundene Schraubkappe des oberen Behälters aus den jeweiligen Öffnungen gelöst, so dass zwischen dem unteren und dem oberen Behälter eine offene Verbindung für die Flüssigkeiten entsteht. Die in den Behältern jeweils enthaltenen Komponenten können so durch leichtes Schütteln des Behältersystems vermischt werden, wobei die beiden Kappen ein Schüttelorgan bilden. Anschliessend kann die auf diese Weise entstandene Zweikomponentenflüssigkeit durch eine getrennte, mittels einer Verschlusskappe zugeschraubte Ausflussöffnung hinausströmen und verwendet werden.When turning, the protruding parts of the screw cap of the lower The container and the guideway of the connecting ring interlock at some point, so that the screw cap is secured against further turning. If the lower container is turned relative to the intermediate ring, will Screw cap now held in place and by the opposite thread of the cap released from the neck of the lower container. That way, ultimately the screw cap of the lower container and the screw cap connected to it the upper container from the respective openings so that between an open connection for the liquids in the lower and the upper container arises. The components contained in the containers can thus be mixed by gently shaking the container system, the two Caps form a shaking organ. Then the one created in this way Two-component liquid through a separate, by means of a cap Flow out the screwed-out orifice and be used.

Im Vergleich zu andern Behältern für Zweikomponentenflüssigkeiten, bei denen die Teile durchgestochen oder aufgeschnitten werden müssen, hat dieses Behältersystem den Vorteil, dass zwischen beiden Behältern eine breite Öffnung für die Flüssigkeiten entsteht, wenn die beiden Verschlusskappen gelöst werden. Ausserdem kann das System nach dem Gebrauch grundsätzlich erneut abgefüllt und wiederverwendet werden.Compared to other containers for two-component liquids where this container system has the parts to be pierced or cut open the advantage that a wide opening for the Liquids are created when the two caps are loosened. Furthermore the system can basically be refilled after use and be reused.

Das vorgenannte Behältersystem hat jedoch den Nachteil, dass Herstellung und Zusammenbau des Systems durch die vielfache Verwendung von Gewindeverbindungen vergleichsweise aufwendig und teuer sind, während der Zusammenbau ausserdem mit besonders grosser Sorgfalt zu erfolgen hat, um zu gewährleisten, dass die Verschlusskappe des oberen Behälters während der Schraubbewegung des unteren Behälters völlig gelöst wird. Ferner kann der Abrissstreifen, der die gegenseitige Lage der beiden Behälter fixiert, nicht wiederverwendet werden, nachdem das System geöffnet worden ist. Damit muss der Verbindungsring insgesamt ersetzt werden.However, the aforementioned container system has the disadvantage that production and Assembly of the system through the multiple use of threaded connections are comparatively complex and expensive during assembly must also be carried out with great care to ensure that that the cap of the upper container during the screwing motion of the lower container is completely released. Furthermore, the tear strip, which fixes the mutual position of the two containers, cannot be reused, after the system has been opened. So that the connecting ring to be replaced altogether.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, ein Behältersystem des oben beschriebenen Typs derart zu verbessern, dass dessen Teile einfacher und kostengünstiger hergestellt und zusammengebaut werden können. Erfindungsgemäss wird diese Aufgabe dadurch erreicht, dass mindestens eine der Verschlusskappen mittels einer Klemmverbindung mit dem Verbindungsstück verbunden ist. Indem die Verschlusskappe auf das Verbindungsstück geklemmt statt geschraubt wird, können Verschlusskappe und Verbindungsstück einfacher ausgeführt werden, wobei die Verbindung der Teile schneller erfolgen kann. Vorteilhafterweise ist die Verschlusskappe auf dem Verbindungsstück festgeschnappt, somit wird eine positive Verbindung der Verschlusskappe mit dem Verbindungsstück erreicht. Mit Vorteil ist zumindest einer der Halter in axialer Richtung nahezu unbeweglich mit dem Verbindungsstück verbunden. Somit ist keine axiale Bewegung zwischen den Behältern mehr erforderlich, um die Kappen zu lösen, so dass auch kein Abreissstreifen mehr benötigt wird und das Verbindungsstück folglich insgesamt wiederverwendet werden kann. Vorteilhafterweise können die Verschlusskappen und der Behälter mittels einer Schnappverbindung am Verbindungsstück befestigt sein, was die Konstruktionsweise und den Zusammenbau weiter vereinfacht. Auf diese Weise wird eine positive Befestigung dieser Teile am Verbindungsstück erreicht. Die andere Verschlusskappe ist vorzugsweise mittels einer Schraubverbindung mit dem jeweiligen Behälter verbunden, wobei das Verbindungsstück Mittel zur Sicherung der Schraubkappe gegen Drehbewegungen aufweist. Auf diese Weise wird eine Drehbewegung des Behälters in eine geradlinige axiale Bewegung der Schraubkappe umgewandelt. Die Sicherungsmittel können dabei mindestens einen zwischen beiden Verschlusskappen befindlichen, mit der Schraubkappe zusammenwirkenden Führungsrand umfassen, der vorzugsweise selbstzentrierend ausgeführt ist, so dass auch dann, wenn die Lage der Schraubkappe gegenüber dem Verbindungsstück nicht genau stimmen sollte, der Führungsrand und die Schraubkappe dennoch ineinandergreifen. Um eine geschlossene Ausgangslage des Behältersystems eindeutig feststellen zu können, weisen vorzugsweise auf jeden Fall der durch die Schraubkappe abschliessbare Behälter und das Verbindungsstück eine nicht-runde Querschnittsform auf. Auf diese Weise ist mit einem Blick erkennbar, ob der Behälter gegenüber seiner Ausgangslage gedreht wurde. Um zu gewährleisten, dass die Schraubkappe beim Drehen des jeweiligen Behälters tatsächlich gelöst ist, weisen der Behälter und das Verbindungsstück vorzugsweise zusammenwirkende, in einer bestimmten Drehrichtung wirksame Sperrmittel, beispielsweise in Form ineinandergreifender Sperrzahnräder, auf. Auf diese Weise kann der Behälter ausschliesslich in der richtigen Richtung gegenüber dem Verbindungsstück gedreht werden. Mit Vorteil sind der durch die Schraubkappe abschliessbare Behälter und das Verbindungsstück zumindest um eine halbe Umdrehung gegenüber einander drehbar. Bei einer asymmetrischen Querschnittsform der Behälter und des Verbindungsstücks wird somit klar erkennbar, in welcher Lage sich das Behältersystem befindet. Um ein unter allen Umständen flüssigkeitsdichtes Behältersystem zu bilden, trotz des Gebrauchs von relativ einfachen Verbindungen zwischen den verschiedenen Teilen, kann zwischen den Behältern zumindest eine Abdichtung angebracht sein. Die Verschlusskappen sind mit Vorteil flüssigkeitsdicht miteinander verbindbar. Somit' bilden sie zusammen einen Treibkörper, wodurch das Lösen der Verschlusskappen aus den Öffnungen vereinfacht wird und dieser Körper gleichzeitig als Schüttelorgan dient, um die verschiedenen Flüssigkeiten zu vermischen.The present invention is based on the object of a container system of the type described above so that its parts easier and can be manufactured and assembled more cheaply. According to the invention this task is achieved in that at least one of the Caps are connected to the connector by means of a clamp connection is. By placing the cap on the connector instead screwed, cap and connector can be made easier be, whereby the connection of the parts can be done faster. Advantageously the cap is snapped onto the connector, thus a positive connection of the closure cap with the connecting piece reached. Advantageously, at least one of the holders is almost in the axial direction immovably connected to the connector. So there is no axial movement between the containers more needed to loosen the caps so that also no tear-off strip is needed and consequently the connecting piece can be reused overall. The closure caps can advantageously and the container by means of a snap connection on the connector be attached to what the construction method and assembly further simplified. In this way, a positive attachment of these parts on Connector reached. The other cap is preferably by means of a screw connection connected to the respective container, the connecting piece Means for securing the screw cap against rotating movements having. In this way, a rotational movement of the container into a straight line axial movement of the screw cap converted. The means of protection can at least one located between the two caps, with the screw cap cooperating guide edge, which preferably is self-centering, so that even when the location the screw cap should not exactly match the connector, the guide edge and the screw cap still mesh. To one to be able to clearly determine the closed starting position of the container system, preferably have the lockable by the screw cap Container and the connector on a non-round cross-sectional shape. In this way it can be seen at a glance whether the container is opposite its Starting position was turned. To ensure that the screw cap when Rotation of the respective container is actually solved, the container and the connector preferably cooperating in a particular Effective blocking means of rotation, for example in the form of interlocking Ratchet gears, on. In this way, the container can only in the the correct direction in relation to the connector. With advantage are the container that can be locked with the screw cap and the connecting piece rotatable relative to one another by at least half a turn. At a asymmetrical cross-sectional shape of the container and the connector the position of the container system is clearly recognizable. Around to form a liquid-tight container system under all circumstances, despite the Using relatively simple connections between the different parts, At least one seal can be attached between the containers. The closure caps can advantageously be connected to one another in a liquid-tight manner. Thus, together they form a propellant, causing the caps to loosen is simplified from the openings and this body at the same time serves as a shaking device to mix the different liquids.

Um die zwei Komponentenflüssigkeiten zu verwenden, kann zumindest einer der Behälter mit einer Spenderöffnung versehen sein, die mittels einer darauf geklemmten Verschlusskappe abschliessbar ist. Dadurch, dass die Verschlusskappe auf die Spenderöffnung geklemmt ist, wird die Konstruktion des Behältersystems zusätzlich vereinfacht.To use the two component liquids, at least one of the Containers can be provided with a dispenser opening which is clamped thereon Locking cap is lockable. Because the cap is clamped onto the dispenser opening, the construction of the container system additionally simplified.

In den Figuren sind für dieselben Elemente jeweils dieselben Bezugszeichen verwendet worden, wenn nicht ausdrücklich anders erwähnt.In the figures, the same reference numerals are used for the same elements unless expressly stated otherwise.

Ein Behältersystem 1 gemäss der Erfindung besteht aus einem oberen Behälter 2 und einem unteren Behälter 3, die mittels eines Verbindungsstücks 4 miteinander verbunden sind (Fig. 1). Wie aus der Fig. 1 ersichtlich haben der obere Behälter 2, das Verbindungsstück 4 und der untere Behälter 3 je eine nicht-runde, insbesondere elliptische Querschnittsform. Die Behälter 2, 3 können unterschiedliche Stoffe (insbesondere Flüssigkeiten) enthalten, die zwar getrennt aufzubewahren, aber in gemischtem Zustand zu verwenden sind, beispielsweise die Bestandteile einer Zweikomponentenflüssigkeit. Die Behälter 2, 3 weisen jeweils eine Mischöffnung 5, 7 auf, die in zusammengebautem Zustand der Behälter 2, 3 einander zugewandt sind. Die Öffnungen 5, 7 sind jeweils mittels einer Verschlusskappe 6, 8 abgeschlossen, wobei die Verschlusskappe 8 auf den Hals des unteren Behälters 3 geschraubt ist, während die Verschlusskappe 6 mittels einer Schnappverbindung 9 mit dem Verbindungsstück 4 verbunden ist und mit welchem der obere Behälter 2 mittels einer Schraubverbindung 10 verbunden ist. Die Öffnung 5 des Behälters 2 wird also sowohl durch das Verbindungsstück 4 als auch durch die Verschlusskappe 6 abgeschlossen. Um eine ordnungsgemässe Abdichtung zu gewährleisten, weist die Verschlusskappe 6 eine umlaufende Nut 38 auf, in die sich das abgeschrägte Ende 28 eines zylinderförmigen Teils 23 des Verbindungsstücks 4 fügt. Ausserdem weist das Verbindungsstück 4 eine umlaufende Dichtungsrippe 27 auf, die mit dem zylinderförmigen Gewindeteil 26 des Verbindungsstücks 4 eine Nut 39 bildet, in die sich ein abgeschrägtes Ende 40 des oberen Behälters 2 fügt. Dementsprechend weist die Verschlusskappe 8 eine umlaufende Nut 33 auf, in die sich ein abgeschrägtes Ende 34 des Halses 31 des unteren Behälters 3 fügt.A container system 1 according to the invention consists of an upper container 2 and a lower container 3 which are connected to one another by means of a connecting piece 4 are connected (Fig. 1). As can be seen from FIG. 1, the upper container 2, the connector 4 and the lower container 3 each have a non-round, in particular elliptical cross-sectional shape. The containers 2, 3 can be different Contain substances (especially liquids) that must be kept separately, but must be used in a mixed state, for example the components a two-component liquid. The containers 2, 3 each have a mixing opening 5, 7 on, in the assembled state of the container 2, 3 facing each other are. The openings 5, 7 are each by means of a closure cap 6, 8 completed, the cap 8 on the neck of the lower container 3 is screwed, while the cap 6 by means of a snap connection 9 is connected to the connector 4 and with which the upper Container 2 is connected by a screw 10. The opening 5 of the Container 2 is thus both through the connector 4 and through Cap 6 completed. To ensure proper sealing ensure, the cap 6 has a circumferential groove 38 into which the beveled end 28 of a cylindrical part 23 of the connecting piece 4 adds. In addition, the connector 4 has a circumferential Sealing rib 27, which with the cylindrical threaded part 26 of the Connector 4 forms a groove 39 into which a beveled end 40th of the upper container 2 inserts. Accordingly, the closure cap 8 has a circumferential groove 33 into which a beveled end 34 of the neck 31 of the lower container 3 inserts.

Der untere Behälter 3 ist mittels einer Schnappverbindung 11, die aus einer umlaufenden Rippe 30 auf dem unteren Behälter 3 und einer umlaufenden Rippe 29 im zylinderförmigen Teil 23 des Verbindungsstücks 4 besteht, mit dem Verbindungsstück verbunden (Fig. 4). Der untere Behälter 3 und das Verbindungsstück 4 weisen ausserdem zusammenwirkende, in einer bestimmten Drehrichtung wirksame Sperrmittel 20 auf, die aus zwei Sägezahnzapfen 21 auf dem unteren Behälter 3 und einer grossen Anzahl damit zusammenwirkender Sperrradzähne 22 an der Unterseite des zylinderförmigen Teils 23 des Verbindungsstücks 4 bestehen. Die Sägezahnzapfen 21 weisen dabei eine vertikal aus der Oberseite des Behälters 3 herausragende Stirnfläche 45 und eine zur Oberseite des Behälters 3 hin geneigte Oberfläche 44 auf (Fig. 3). Ausserdem weist das Verbindungsstück 4 Mittel 13 zur Sicherung der festgeschraubten Verschlusskappe 8 gegen Drehbewegungen auf. Diese Sicherungsmittel bestehen aus vier parallele Führungsleisten 14, die paarweise einander diametral gegenüberliegend längs der Innenwand des zylinderförmigen Teils 23 des Verbindungsstücks 4 angeordnet sind (vgl. Fig. 2). Zwei paarweise angeordnete Führungsleisten 14 bilden dabei jeweils eine Führungsnut 49, in die ein Führungszapfen 32 der Schraubkappe 8 geführt ist. The lower container 3 is by means of a snap connection 11, which consists of a rotating Rib 30 on the lower container 3 and a circumferential rib 29 in the cylindrical part 23 of the connector 4, with the connector connected (Fig. 4). The lower container 3 and the connector 4 also have interacting, effective in a certain direction of rotation Locking means 20 on the two sawtooth pins 21 on the lower container 3 and a large number of ratchet teeth 22 interacting therewith exist on the underside of the cylindrical part 23 of the connecting piece 4. The sawtooth pins 21 have a vertical from the top of the Container 3 protruding end face 45 and one to the top of the container 3rd inclined surface 44 (Fig. 3). In addition, the connector 4 Means 13 for securing the screwed cap 8 against rotary movements on. These securing devices consist of four parallel guide rails 14, which are diametrically opposed in pairs along the inner wall of the cylindrical part 23 of the connecting piece 4 are arranged (cf. 2). Two guide strips 14 arranged in pairs each form a guide groove 49, into which a guide pin 32 of the screw cap 8 is guided.

Die Schraubkappe 8 besitzt an der Oberseite ausserdem einige vorspringende Segmente 35, die jeweils einen nach aussen vorspringenden Schnapprand 36 aufweisen (Fig. 4). Entsprechend weist die Verschlusskappe 6 einen umlaufenden Flansch 50 auf, der einen nach innen vorspringenden Schnapprand 37 aufweist. Dadurch dass die vorspringenden Teile 35 als Segmente ausgeführt sind und keinen ununterbrochenen Flansch bilden, sind diese gegenüber den übrigen Teilen der Konstruktion vergleichsweise flexibel oder biegsam.The screw cap 8 also has some protruding on the top Segments 35, each of which has an outwardly projecting snap edge 36 have (Fig. 4). Correspondingly, the closure cap 6 has a circumferential one Flange 50, which has an inwardly projecting snap edge 37. Because the projecting parts 35 are designed as segments and none form continuous flange, these are compared to the other parts the construction is comparatively flexible or pliable.

Der obere Behälter 2 weist an der gegenüber der Mischöffnung 5 liegenden Seite noch eine Ausflussöffnung 15 auf, die mittels einer Verschlusskappe 16 abgeschlossen ist, die mittels einer Schnappverbindung 17 darauf befestigt ist. Die Verschlusskappe 16 besteht dabei aus einem Ausflusskörper, der in eine vergleichsweise enge Ausflussöffnung 18 mündet, die mittels einer Kappe 19 abgeschlossen ist, die mittels einer Schraubverbindung 48 darauf angebracht ist. Statt einer Schraubverbindung könnte dazu selbstverständlich ebenfalls eine Schnappverbindung mit abdichtenden Schnapprändern gemäss den Rändern 46 und 47 der Schnappverbindung 17 verwendet werden.The upper container 2 has on the side opposite the mixing opening 5 still an outflow opening 15, which is closed by a cap 16 which is fastened thereon by means of a snap connection 17. The Closure cap 16 consists of a discharge body, which is comparatively narrow outflow opening 18, which is closed by a cap 19 which is mounted thereon by means of a screw connection 48. Instead of a screw connection could of course also be a snap connection with sealing snap edges according to edges 46 and 47 the snap connection 17 can be used.

Vor dem Gebrauch des Behältersystems 1 wird zuerst der untere Behälter 3 mit der betreffenden Flüssigkeit abgefüllt und mittels der Verschlusskappe 8 festgeschraubt. Anschliessend wird der untere Behälter 3 samt darauf geschraubter Verschlusskappe 8 in das Verbindungsstück 4 eingeschnappt, wobei die Führungszapfen 32 in die Führungsnuten 49 greifen. Danach kann die Verschlusskappe 6 des oberen Behälters 2 auf dem Verbindungsstück 4 eingeschnappt und der obere Behälter 2 in das Verbindungsstück 4 geschraubt werden, wonach der obere Behälter 2 über die Öffnung 15 abgefüllt werden kann, bevor diese Öffnung mittels der Verschlusskappe 16 abgeschlossen wird. Andererseits ist es auch möglich, zuerst die Verschlusskappe 16 auf dem oberen Behälter 2 zu befestigen, den Behälter danach umzukehren und über die Mischöffnung 5 abzufüllen, um anschliessend den übrigen Teil des Behältersystems (d. h. den unteren Behälter 3, das Verbindungsstück 4 und die darauf eingeschnappte Verschlusskappe 6) in umgekehrtem Zustand auf den oberen Behälter 2 zu schrauben. In diesem Zustand können jetzt die beiden Komponenten in den Behältern 2 und 3 getrennt voneinander aufbewahrt werden. Die nicht runden, im obigen Beispiel ellipsenförmigen Querschnittsformen des unteren Behälters 3 und des Verbindungsstücks 4 fügen sich dabei aneinander, so dass von der Aussenseite des Behältersystems 1 mit einem Blick erkennbar ist, dass die Behälter 2 und 3 tatsächlich in gebrauchsfertigem Zustand abgeschlossen sind.Before using the container system 1, the lower container 3 is first used filled the liquid in question and screwed tight by means of the cap 8. Then the lower container 3 is screwed onto it Cap 8 snapped into the connector 4, the guide pin 32 engage in the guide grooves 49. Then the cap 6 of the upper container 2 snapped onto the connector 4 and the upper container 2 are screwed into the connector 4, after which the Upper container 2 can be filled through the opening 15 before this opening is completed by means of the closure cap 16. On the other hand, it is too possible to first fasten the cap 16 on the upper container 2, then invert the container and fill it through the mixing opening 5 in order to then the remaining part of the container system (i.e. the lower container 3, the connector 4 and the snap cap 6) snapped onto it reverse state to screw on the upper container 2. In this condition can now separate the two components in containers 2 and 3 be kept apart. The non-round, elliptical in the example above Cross-sectional shapes of the lower container 3 and the connector 4 fit together so that from the outside of the container system 1 It can be seen at a glance that containers 2 and 3 are actually ready for use Condition are complete.

Wenn der Inhalt des Behältersystems 1 nun verwendet werden soll, müssen zuerst die beiden Komponenten in den Behältern 2 und 3 vermischt werden. Dazu wird der untere Behälter 3 gegenüber dem Verbindungsstück 4 in der von den Sperrmitteln 20 zugelassenen Richtung gedreht (Pfeile R1; Fig. 3). Dabei kann die Schraubkappe 8 nicht mit dem unteren Behälter 3 mitdrehen, weil sie durch die Führungsleisten 14 gegen Drehbewegungen gesichert ist. Die Schraubkappe 8 wird also gegenüber dem unteren Behälter 3 eine gegenläufige Drehbewegung ausführen, wodurch diese sich vom Hals 31 des unteren Behälters 3 löst. Dabei bewegt sich die Schraubkappe 8 nach oben, bis sich die Schnappränder 36 der vorspringenden Segmente 35 am Schnapprand 37 der oberen Verschlusskappe 6 verhaken und der Flansch 50 der oberen Verschlusskappe 6 auf der Oberseite der Schraubkappe 8 ruht.If the contents of the container system 1 are now to be used, the two components in the containers 2 and 3 must first be mixed. For this purpose, the lower container 3 is rotated relative to the connecting piece 4 in the direction permitted by the locking means 20 (arrows R 1 ; FIG. 3). The screw cap 8 cannot rotate with the lower container 3 because it is secured against rotation by the guide strips 14. The screw cap 8 will therefore perform an opposite rotational movement with respect to the lower container 3, as a result of which it detaches from the neck 31 of the lower container 3. The screw cap 8 moves upwards until the snap edges 36 of the projecting segments 35 hook onto the snap edge 37 of the upper sealing cap 6 and the flange 50 of the upper sealing cap 6 rests on the top of the screw cap 8.

Wenn der untere Behälter 3 jetzt weitergedreht, wird die obere Verschlusskappe 6 durch die weitere Bewegung der Schraubkappe 8 nach oben (in die durch Pfeil L angegebene Richtung; Fig. 4) mitgeführt, so dass die Schnappverbindung 9 zwischen der Verschlusskappe 6 und dem Verbindungsstück 4 getrennt wird. Jetzt erreicht die Schraubkappe 8 ebenfalls das Ende des Gewindeteils des Halses 31, so dass die beiden Verschlusskappen 6, 8 sich vom Verbindungsstück 4 bzw. vom unteren Behälter 3 lösen und zwischen den einander zugewandten Öffnungen 5 und 7 des oberen Behälters 2 und des unteren Behälters 3 eine offene Verbindung für die Flüssigkeiten entsteht. Die darin enthaltenen Komponenten können somit durch Schütteln des Behältersystems 1 vermischt werden, wobei die miteinander verbundenen Verschlusskappen 6 und 8, die in der Flüssigkeit im oberen Behälter 2 schweben, wie ein Schüttelorgan wirken. Die vermischte Zweikomponentenflüssigkeit kann letztendlich nach Entfernung der Kappe 19 oder gar der Verschlusskappe 16 durch die Ausflussöffnung 15 hinausströmen.If the lower container 3 now continues to rotate, the upper closure cap 6 by the further movement of the screw cap 8 upwards (into the direction indicated by arrow L specified direction; Fig. 4) carried so that the snap connection 9 between the cap 6 and the connector 4 is separated. Now the screw cap 8 also reaches the end of the threaded part of the neck 31, so that the two caps 6, 8 protrude from the connector 4 or detach from the lower container 3 and between the mutually facing openings 5 and 7 of the upper container 2 and the lower container 3 an open connection for the liquids. The components it contains can thus be mixed by shaking the container system 1, the interconnected caps 6 and 8 in the liquid in the upper container 2 float, act like a shaking organ. The mixed two-component liquid can ultimately after removal of the cap 19 or even of the closure cap 16 flow out through the outflow opening 15.

Bei einer alternativen Ausführung des Behältersystems gemäss der Erfindung (Fig. 5) ist der untere Behälter 3 mittels eines Bajonettverschlusses mit dem Verbindungsstück 4 verbunden. Dazu ist der untere Behälter 3 mit einem umlaufenden Rand 54 mit zwei einander gegenüberliegenden Aussparungen 55 und 56 versehen, während das Verbindungsstück 4 zwei mit den Aussparungen übereinstimmenden Nocken 57 und 58 aufweist, die von der Innenwand des zylindrischen Teiles 23 des Verbindungsstücks 4 nach innen vorstehen. Der Nocken 57 und die zugehörige Aussparung 55 haben dabei andere Abmessungen als der Nocken 58 und die Aussparung 56, so dass das Verbindungsstück nur auf eine Weise mit dem unteren Behälter 3 befestigt werden kann. Die Aussparungen 55, 56 und die Nocken 57, 58 sind derart ausgebildet, dass der untere Behälter 3 nur in einer Richtung gegenüber dem Verbindungsstück 4 gedreht werden kann, nachdem die Nocken in die Aussparungen hineingebracht worden sind. Dazu weist jede Aussparung 55, 56 an einer Seite eine nach unten abgeschrägte Fläche 63 auf, die als Führung für die Drehbewegung des unteren Behälters 3 gegenüber dem Zwischenstück 4 dient, während die gegenüberliegende Fläche 64 jeder Aussparung 55, 56 als Anschlag dient und eine Verdrehung des unteren Behälters 3 in eine andere Richtung verhindert. Die Aussparungen 55, 56 sind wie gesagt einander diametral gegenüberliegend im Rand 54 angebracht, und sind im gezeigten Beispiel symmetrisch in Bezug auf die kurze Symmetrieachse des unteren Behälters 3. Die Nocken 57, 58, die ebenfalls einander diametral gegenüberliegen, sind ungefähr zwischen der kurzen und der langen Symmetrieaxe des Verbindungsstücks 4 vorgesehen, so dass der untere Behälter 3 mit dem Verbindungsstück 4 einen Winkel von ungefähr 45 Grad einschliesst, wenn die Nocken 57, 58 gerade in die Aussparungen 55, 56 hineingedrückt werden können. Dadurch dass der untere Behälter 3 und das Zwischenstück 4 eine nicht-runde Querschnittsform aufweisen, ist dieser Winkel zwischen den beiden Teilen klar ersichtlich und bildet somit eine sehr gute Anzeige für den momentanen Zustand beim Zusammenbau des Behältersystems 1.In an alternative embodiment of the container system according to the invention (Fig. 5) is the lower container 3 by means of a bayonet lock with the connector 4 connected. For this purpose, the lower container 3 with a rotating one Edge 54 with two mutually opposite cutouts 55 and 56 provided while the connecting piece 4 two matching with the recesses Has cams 57 and 58 extending from the inner wall of the cylindrical Project part 23 of the connector 4 inwards. The cam 57 and the associated recess 55 have different dimensions than the cam 58 and the recess 56 so that the connector only has one way the lower container 3 can be attached. The recesses 55, 56 and Cams 57, 58 are designed such that the lower container 3 only in one Direction relative to the connector 4 can be rotated after the Cams have been inserted into the recesses. Each recess has this 55, 56 on one side a downwardly beveled surface 63, the as a guide for the rotational movement of the lower container 3 relative to the intermediate piece 4 serves while the opposite surface 64 of each recess 55, 56 serves as a stop and a rotation of the lower container 3 in one other direction prevented. The recesses 55, 56 are, as I said, one another attached diametrically opposite in the edge 54, and are in the example shown symmetrical with respect to the short axis of symmetry of the lower container 3. The cams 57, 58, which are also diametrically opposite one another, are approximate between the short and the long axis of symmetry of the connector 4 is provided so that the lower container 3 with the connector 4 a Includes an angle of approximately 45 degrees when the cams 57, 58 are just in the Recesses 55, 56 can be pressed. By making the lower one Container 3 and the intermediate piece 4 have a non-round cross-sectional shape, this angle between the two parts is clearly visible and thus forms one very good display for the current state when assembling the container system 1.

Um den Hals 31 des unteren Behälters 3 ist unten am Rand 54 noch eine ringförmige Abdichtung 62 eines federelastisch verformbaren Materials, beispielsweise eines gummiartigen Materials, angebracht. Dieser Abdichtungsring 62 wirkt in montiertem Zustand des Behältersystems 1 mit dem unteren Rand 65 des zylindrischen Teils 23 des Zwischenstücks 4 zusammen, um ein Ausfliessen der Flüssigkeit am Bajonettverschluss zu verhindern. Der untere Rand 65 des zylindrischen Teiles 23 wird dazu kräftig gegen den Abdichtungsring 62 gedrückt, wenn die Nocken 57, 58 bei einer Drehung des unteren Behälters 3 in Bezug auf das Zwischenstück 4 unter den Rand 54 gedrängt werden.Around the neck 31 of the lower container 3 there is still an annular bottom edge 54 Sealing 62 of a resiliently deformable material, for example a rubber-like material. This sealing ring 62 acts in assembled state of the container system 1 with the lower edge 65 of the cylindrical Part 23 of the intermediate piece 4 together to allow the liquid to flow out to prevent the bayonet catch. The lower edge 65 of the cylindrical Part 23 is pressed firmly against the sealing ring 62 when the cams 57, 58 upon rotation of the lower container 3 with respect to the Intermediate piece 4 are pushed under the edge 54.

Nachdem der untere Behälter 3 und das Zwischenstück 4 zusammengesteckt worden sind, kann der untere Behälter 3 verdreht werden in einen für den Gebrauch fertig abgeschlossenen Zustand, wobei der Aussenumriss des unteren Behälters 3 an denjenigen des Zwischenstücks 4 anschliesst (Fig. 6). In diesem Zustand werden die beiden Teile gegenüber einander verriegelt, indem die Nokken 57, 58 in den Aussparungen 60 bzw. 61 unterhalb des Randes 64 ruhen. Zumindest eine dieser Aussparungen, in diesem Beispiel die Aussparung 60, ist dabei mit einem nach unten vorstehenden Rand 66 (Fig. 7) versehen, der als Anschlag dient und das Zurückdrehen des unteren Behälters 3 verhindert.After the lower container 3 and the intermediate piece 4 are plugged together the lower container 3 can be twisted into one for use Completely closed state, the outer outline of the lower Container 3 connects to that of the intermediate piece 4 (Fig. 6). In this Condition the two parts are locked against each other by the cams 57, 58 rest in the recesses 60 and 61 below the edge 64. At least one of these recesses, in this example the recess 60, is present provided with a downwardly projecting edge 66 (Fig. 7) which acts as a stop serves and prevents the lower container 3 from turning back.

Falls der Inhalt des Behältersystems 1 zu verwenden ist, wird der untere Behälter 3 in Bezug auf das Zwischenstück 4 wieder verdreht (Pfeil R2; Fig. 6), in diesem Fall um eine halbe Umdrehung. Dabei werden die Nocken 57, 58 aus den Aussparungen 60, 61 hinaus etwas nach unten gedrückt, wodurch der untere Rand 65 des Zwischenstücks 4 mit zusätzlicher Kraft auf die obere Fläche des Abdichtungsrings 62 gedrückt wird, und eine gute Dichtung gewährleistet ist, auch wenn die Toleranzen der Ausmasse der verschiedenen Teile des Behältersystems 1 infolge Materialverformung mit der Zeit zugenommen haben. Am Ende der halben Umdrehung liegen die Nocken 57, 58 in den gegenüberliegenden Aussparungen 60 bzw. 61, so dass der untere Behälter 3 wieder gegen Zurückdrehen verriegelt wird. Wegen des Anschlagrandes 59 (Fig. 5) oben auf dem Bajonettrand 54, der mit einem längeren Führungsrand 14 des Zwischenstücks 4 zusammenwirkt, wird ausserdem verhindert, dass der untere Behälter 3 noch weiter drehen kann. Die verschiedenen Teile des Behältersystems 1 können somit nicht weiter bewegt werden.If the content of the container system 1 is to be used, the lower container 3 is rotated again with respect to the intermediate piece 4 (arrow R 2 ; FIG. 6), in this case by half a turn. The cams 57, 58 are pressed out of the recesses 60, 61 somewhat downward, as a result of which the lower edge 65 of the intermediate piece 4 is pressed onto the upper surface of the sealing ring 62 with additional force, and a good seal is ensured, even if the Tolerances of the dimensions of the different parts of the container system 1 have increased over time as a result of material deformation. At the end of half a turn, the cams 57, 58 lie in the opposite cutouts 60 and 61, respectively, so that the lower container 3 is locked again against turning back. Because of the stop edge 59 (FIG. 5) on top of the bayonet edge 54, which cooperates with a longer guide edge 14 of the intermediate piece 4, it is also prevented that the lower container 3 can rotate even further. The various parts of the container system 1 can therefore not be moved further.

Sowohl die Schraubkappe 8 als auch die eingeschnappte Verschlusskappe 6 zeigen bei dieser Ausführung eine etwas andere Form als diejenigen der ersten Ausführung. Beide Verschlusskappen 6, 8 sind mit einem halbkugelförmigen Teil 52 bzw. 53 versehen, die zusammen eine flüssigkeitsdichte Kugel bilden, wenn die Verschlusskappen miteinander in Kontakt gebracht worden sind. Dazu ist die Schraubkappe 8 mit einem vorstehenden Rand 67 versehen, der eng umschliessend auf einen nach unten vorstehenden Rand 68 der Verschlusskappe 6 eingeschnappt werden kann. Die Verschlusskappe 6 ist zur Bildung einer Schnappverbindung 9 im übrigen mit einem ununterbrochenen Klemmrand 43 an der Aussenseite des umlaufenden Flansches 50 versehen, der in eine Nut 51 in der Innenwand des zylindrischen Teiles 23 des Zwischenstücks 4 hineingreift. Dadurch dass der Rand 43 und die Nut 51 relativ flach ausgeführt sind, kann die Schnappverbindung einfacher gelöst werden.Both the screw cap 8 and the snap-in cap 6 show in this version a slightly different shape than that of the first Execution. Both caps 6, 8 are with a hemispherical part 52 or 53 provided, which together form a liquid-tight ball, if the caps have been brought into contact with each other. This is the Screw cap 8 is provided with a protruding edge 67 which is closely surrounding snapped onto a downwardly projecting edge 68 of the closure cap 6 can be. The closure cap 6 is to form a snap connection 9 otherwise with an uninterrupted clamping edge 43 on the outside of the circumferential flange 50 provided in a groove 51 in the inner wall of the cylindrical part 23 of the intermediate piece 4 engages. Thereby that the edge 43 and the groove 51 are made relatively flat, the snap connection be solved more easily.

Während der Drehung des unteren Behälters 3 wird die Schraubkappe 8 ähnlich wie bei der ersten Ausführung gegen - weiterer - Verdrehung blockiert, indem die vorstehenden Nocken 32 mit den Rändern 14 des Zwischenstücks 4 in Angriff gelangen. Auch wenn die Nocken 32 zunächst noch nicht an den Rändern 14 anstehen, wird durch eine geringe Drehung der Schraubkappe 8 diesen Zustand bald erreicht, d.h. die Ränder 14 haben darauf eine selbstzentrierende Wirkung. Die Schraubkappe 8 wird somit auf den Hals 31 des unteren Behälters 3 nach oben bewegt. Dabei wird diese mit der Verschlusskappe 6 des oberen Behälters 2 in Kontakt treten und somit durch das Zusammenklemmen der Ränder 67, 68 eine flüssigkeitsdichte Verbindung bilden (Fig. 9). Da der kugelförmige Raum zwischen den beiden Verschlusskappen 6, 8 mit Luft gefüllt wird, werden die eine Kugel bildenden Verschlusskappen 6, 8 aus der Öffnung des Zwischenstücks 4 zum oberen Behälter 2 nach oben getrieben. Durch den Auftrieb dieser Verschlusskappen 6, 8 wird das Lösen derselben einfacher. Die Verschlusskappen 6, 8 werden des weiteren ausgezeichnet als Schüttelorgan dienen, wenn sie im oberen Behälter 2 treiben, wodurch die Vermischung der beiden Flüssigkeitskomponenten verbessert wird.During the rotation of the lower container 3, the screw cap 8 becomes similar as in the first version blocked against further rotation by the protruding cam 32 with the edges 14 of the intermediate piece 4 in attack reach. Even if the cams 32 are not yet in contact with the edges 14, is a small rotation of the screw cap 8 this state reached soon, i.e. the edges 14 have a self-centering effect thereon. The screw cap 8 is thus on the neck 31 of the lower container 3 after moved up. This is with the cap 6 of the upper container 2nd come into contact and thus by clamping the edges 67, 68 together Form liquid-tight connection (Fig. 9). Because the spherical space between the two caps 6, 8 is filled with air, they form a ball Caps 6, 8 from the opening of the intermediate piece 4 to the upper Tray 2 pushed up. The buoyancy of these caps 6, 8 solving them becomes easier. The caps 6, 8 are the serve as a shaking device if they are in the upper container 2 drive, which improves the mixing of the two liquid components becomes.

Da im Behältersystem 1 gemäss der vorliegenden Erfindung viele verschiedene Schnappverbindungen verwendet werden können, lassen sich die einzelnen Teile des Behältersystems leicht herstellen und zusammenbauen. Ausserdem brauchen die Behälter 2, 3 zum Lösen der Verschlusskappen 6, 8 nicht in axialer Richtung gegenseitig bewegt zu werden, wie es bei dem Behältersystem der vorhin genannten deutschen Patentanmeldung 19635833 der Fall ist, so dass auch keine Sperrvorrichtungen in Form eines Abrissstreifens mehr benötigt werden, um die beiden Behälter 2, 3 in der Ausgangslage gegenseitig zu fixieren. Alle Teile des Behältersystems 1 können folglich grundsätzlich nachgefüllt und wiederverwendet werden, so dass weniger Abfall entsteht.Since in the container system 1 according to the present invention, many different The individual parts can be used with snap connections of the container system easy to manufacture and assemble. Also need the containers 2, 3 for loosening the caps 6, 8 not in the axial direction to be moved mutually, as is the case with the container system of the aforementioned German patent application 19635833 is the case, so that also none Locking devices in the form of a tear-off strip are needed to the more to fix both containers 2, 3 to each other in the starting position. All parts of the Container system 1 can therefore basically be refilled and reused so there’s less waste.
