  • at least one component is formed by at least one, for example detachable or catalytically active, solid body which can be brought together as a whole with the other component by the design according to the invention, since the closure completely covers the transfer path or the transfer opening releases. Due to the manually operated discharge pump connected to the main chamber in the operating state, the mixed medium can then be discharged very easily in, for example, precisely metered quantity units, so that above all those mixed media can be used which are detrimental to aerosols or similar propellants.
  • a diaphragm which is to be destroyed by a riser pipe of a valve head is provided as a closure between two chambers and generally tends to lie relatively closely around the riser pipe, so that if the upper chamber were to accommodate an admixture component, a safe passage of this admixture component into the main chamber is not guaranteed would.

Abstract

Eine Austragvorrichtung (l) weist für jede der miteinander in einer Hauptkammer (4) zu mischenden Zumischkomponenten eine Zumischkammer (5) auf, die in eine durch einen Gefäßhals gebildete Halterung (7) der Hauptkammer (4) eingesetzt ist. Eine Wandung der Zumischkammer (5) ist im wesentlichen als Verschlußteil (l7) ausgebildet, der über eine Sollbruchstelle (l8) einteilig mit der Zumischkammer (5) verbunden ist und einen Bestandteil eines Steigrohres (6) bildet. Zur Inbetriebnahme der Austragvorrichtung wird ein Verschluß geöffnet und eine Austragpumpe (3) innerhalb der Halterung (7) in die Zumischkammer (5) derart eingesetzt, daß die Austragpumpe (3) mit einem Ansaugstutzen (27) unter Öffnung eines Rohrverschlusses mit dem Steigrohr (6) verbunden und danach durch weiteres axiales Verschieben des Steigrohres (6) der Verschlußteil (l7) freigebrochen wird, so daß die Komponente aus der Zumischkammer (5) in die Hauptkammer (4) fließt. Durch Betätigung der Austragpumpe (3) läßt sich dann das Mischmedium unmittelbar über den Austragkanal (38) der Austragpumpe (3) austragen.A discharge device (1) has a mixing chamber (5) for each of the mixing components to be mixed in a main chamber (4), which is inserted into a holder (7) of the main chamber (4) formed by a neck of the vessel. One wall of the admixing chamber (5) is essentially designed as a closure part (l7), which is connected in one piece to the admixing chamber (5) via a predetermined breaking point (l8) and forms part of a riser pipe (6). To start up the discharge device, a closure is opened and a discharge pump (3) is inserted into the admixing chamber (5) within the holder (7) in such a way that the discharge pump (3) with an intake port (27) opens a pipe closure with the riser pipe (6 ) connected and then by further axial displacement of the riser pipe (6) the closure part (l7) is broken free so that the component flows from the admixing chamber (5) into the main chamber (4). By actuating the discharge pump (3), the mixed medium can then be discharged directly via the discharge channel (38) of the discharge pump (3).

Description

Die Erfindung betrifft eine Austragvorrichtung für Mischme­dien aus mindestens zwei Komponenten, mit einer Hauptkammer und mindestens einer gegenüber dieser mit einem zur Öffnung von außen zugänglichen Verschlußteil geschlossenen Zumisch­kammer, deren Komponente nach Öffnung des Verschlusses in die Hauptkammer überführbar ist.The invention relates to a discharge device for mixed media comprising at least two components, with a main chamber and at least one admixing chamber closed with respect to the latter with a closure part which is accessible from the outside for opening, the component of which can be transferred into the main chamber after the closure has been opened.

Technische, pharmazeutische, kosmetische und ähnliche Medien bestehen häufig aus mehreren Komponenten, die aus Gründen einer Reaktionszeit oder weil sie im gemischten Zustand zu Veränderungen, beispielsweise geringerer Haltbarkeit neigen, möglichst erst kurz vor Gebrauch gemischt werden sollten. Daher werden solche Mischmedien in der Regel getrennt von­einander in gesonderten Gefäßen bereitsgestellt und vor dem Gebrauch muß die Zumisch-Komponente nach Öffnen des zugehö­rigen Gefäßdeckels der Hauptkomponente zugegeben sowie mit dieser durchmischt werden. Hierzu bedarf es einiger Ge­schicklichkeit und auch hoher Sorgfalt, wenn es darauf an­ kommt, daß die Komponenten in einem genauen Mengenverhältnis miteinander gemischt werden. Ist mindestens eine Komponente von der Art, daß ihr eine unmittelbare Berührung mit Luft abträglich ist, so kann die Mischung praktisch nur unter La­borbedingungen erfolgen.Technical, pharmaceutical, cosmetic and similar media often consist of several components, which should only be mixed shortly before use for reasons of a reaction time or because they tend to change in the mixed state, for example less durability. Such mixed media are therefore usually provided separately from one another in separate vessels and, before use, the admixing component must be added to the main component after opening the associated vessel lid and mixed with it. This requires some skill and also great care when it comes down to it comes that the components are mixed together in an exact quantitative ratio. If at least one component is such that direct contact with air is detrimental to it, the mixing can practically only take place under laboratory conditions.

Der Erfindung liegt die Aufgabe zugrunde, eine Austragvor­richtung der genannten Art zu schaffen, bei welcher auf ein­fache Weise das Zumischen mindestens einer Komponente zu mindestens einer weiteren Komponente in einfacher Weise so vorgenommen werden kann, daß ein sicheres und vollständiges Übertreten der einen Komponente in die Kammer der anderen Komponente gewährleistet ist und daß danach das Mischmedium unmittelbar aus der zugehörigen Kammer für den Gebrauch aus­getragen werden kann, ohne daß die Hauptkammer unter Druck gesetzt werden muß.The invention has for its object to provide a discharge device of the type mentioned, in which the admixing of at least one component to at least one further component can be carried out in a simple manner so that a safe and complete transfer of the one component into the chamber the other component is guaranteed and that the mixed medium can then be discharged directly from the associated chamber for use without the main chamber having to be pressurized.

Zur Lösung dieser Aufgabe ist bei einer Austragvorrichtung der eingangs genannten Art gemäß der Erfindung vorgesehen, daß mindestens eine Zwischenkammer über den Verschlußteil unmittelbar an die Hauptkammer angrenzt, daß der Verschluß­teil über eine Sollbruchstelle aus der Verschlußlage ab­trennbar ist und daß die Hauptkammer eine Halterung für eine saugseitig an ihren Innenraum anzuschließende handbetätig­bare Austragpumpe aufweist. Die Zwischenkammer und die Hauptkammer sind also beispielsweise über eine in einer ge­meinsamen Wandung vorgesehene, zunächst mit dem Verschluß­teil geschlossen gehaltene Übertrittsöffnung unmittelbar miteinander leitungsverbunden, so daß nach Abtrennen des Verschlußteiles die Übertrittsöffnung im wesentlichen auf ihrer gesamten, durch ihre formstabile Begrenzung genau de­finierten Weite offen ist und der Inhalt der einen Kammer unter Umgehung irgendwelcher Leckverluste unmittelbar in die andere Kammer überführt werden kann. Die zu mischenden Kom­ponenten, die zweckmäßig fließfähig sind, können Flüssigkei­ten, pulverförmige Substanzen, Gase o.dgl. sein, wobei auch jede der genannten Aggregatformen zur Mischung mit einer beliebigen der beiden anderen Aggregatformen vorgese­hen sein kann. Beispielsweise kann die Zumischkomponente pulverförmig und die Hauptkomponente flüssig sein. Es ist aber des weiteren auch denkbar, daß mindestens eine Kompo­nente durch wenigstens einen, beispielsweise lösbaren oder katalytisch wirkenden Festkörper gebildet ist, der durch die erfindungsgemäße Ausbildung als Ganzes mit der anderen Kom­ponente zusammengebracht werden kann, da der Verschluß den Übertrittsweg bzw. die Übertrittsöffnung vollständig frei­gibt. Durch die im Betriebszustand an die Hauptkammer ange­schlossene handbetätigbare Austragpumpe läßt sich das Misch­medium dann in beispielsweise genau dosierten Mengeneinhei­ten sehr einfach austragen, so daß vor allem solche Mischme­dien zur Anwendung kommen können, denen Aerosole oder ähnli­che Treibmittel abträglich sind.To solve this problem it is provided in a discharge device of the type mentioned according to the invention that at least one intermediate chamber directly adjoins the main chamber via the closure part, that the closure part can be separated from the closed position via a predetermined breaking point and that the main chamber has a holder for a suction side has to be connected to its interior manually operated discharge pump. The intermediate chamber and the main chamber are thus, for example, directly connected to one another via a transition opening provided in a common wall and initially kept closed with the closure part, so that after the closure part has been removed, the transition opening is essentially open over its entire width, which is precisely defined by its dimensionally stable limitation and the contents of one chamber can be transferred directly to the other chamber, avoiding any leakage losses. The components to be mixed, which are expediently flowable, can be liquids, powdery substances, gases or the like. be where each of the aforementioned forms of aggregate can also be provided for mixing with any of the two other aggregate forms. For example, the admixing component can be in powder form and the main component can be liquid. However, it is also conceivable that at least one component is formed by at least one, for example detachable or catalytically active, solid body which can be brought together as a whole with the other component by the design according to the invention, since the closure completely covers the transfer path or the transfer opening releases. Due to the manually operated discharge pump connected to the main chamber in the operating state, the mixed medium can then be discharged very easily in, for example, precisely metered quantity units, so that above all those mixed media can be used which are detrimental to aerosols or similar propellants.

Durch die US-PS 32 40 403 ist zwar eine Austragvorrichtung mit zwei durch einen Zwischendeckel getrennten Kammern be­kanntgeworden, bei welcher die obere Kammer das auszutragen­de Medium und die untere Kammer ein Treibgas enthält, das nicht als Mischkomponente, sondern lediglich zur Erzeugung eines das Medium über einen Ventilkopf nach außen fördernden Druckes vorgesehen ist. Eine Deckelplatte zwischen den bei­den Kammern wird unter dem Gasdruck in Verschlußlage gehal­ten, weshalb diese Ausbildung nicht zum Zusammenmischen ge­trennt gehaltener Mischkomponenten wie beim Erfindungsgegen­stand geeignet ist. Bei einer anderen, durch die US-PS 3l 34 505 bekanntgewordenen Austragvorrichtung ist als Ver­schluß zwischen zwei Kammern eine durch ein Steigrohr eines Ventilkopfes zu zerstörende Membran vorgesehen, die in der Regel dazu neigt, sich relativ eng um das Steigrohr zu le­gen, so daß, falls die obere Kammer zur Aufnahme einer Zu­mischkomponente vorgesehen wäre, ein sicherer Übertritt die­ser Zumischkomponente in die Hauptkammer nicht gewährleistet wäre. Dadurch, daß beim Erfindungsgegenstand der Verschluß­teil über mindestens eine Sollbruchstelle abtrennbar ist, werden die genannten Nachteile vermieden.From US-PS 32 40 403 a discharge device with two chambers separated by an intermediate cover has become known, in which the upper chamber contains the medium to be discharged and the lower chamber contains a propellant gas which is not used as a mixing component, but only for producing a medium a valve head to the outside promoting pressure is provided. A cover plate between the two chambers is kept in the closed position under the gas pressure, which is why this design is not suitable for mixing separately kept mixing components as in the subject of the invention. In another discharge device which has become known from US Pat. No. 3l 34 505, a diaphragm which is to be destroyed by a riser pipe of a valve head is provided as a closure between two chambers and generally tends to lie relatively closely around the riser pipe, so that if the upper chamber were to accommodate an admixture component, a safe passage of this admixture component into the main chamber is not guaranteed would. Because the closure part in the subject matter of the invention can be separated via at least one predetermined breaking point, the disadvantages mentioned are avoided.

Eine besonders vorteilhafte Weiterbildung des Erfindungsge­genstandes besteht darin, daß die Zumischkammer in die vor­zugsweise nach Art eines Gefäßhalses ausgebildete Halterung für die Austragpumpe eingesetzt ist, so daß sie bei normaler Standstellung der Hauptkammer in der Regel oberhalb von de­ren Inhalt liegt und deshalb der Inhalt der Zumischkammer nach Öffnen des Verschlußteiles unter seiner Gewichtskraft von selbst in die Hauptkammer gelangt. Es ist zwar denkbar, die Wandungen der Zumischkammer einteilig mit denen der Hauptkammer auszubilden, jedoch ergibt sich eine besonders einfach herzustellende und zu handhabende Ausführungsform, wenn die Zumischkammer in Form eines gesonderten, in die Hauptkammer eingesetzten Behältnisses vorgesehen ist, das vorzugsweise an der äußeren Stirnfläche der Halterung für die Austragpumpe mit einem Flanschring abgedichtet anliegt.A particularly advantageous development of the subject matter of the invention is that the admixing chamber is inserted into the holder for the discharge pump, which is preferably designed in the manner of a neck of the vessel, so that when the main chamber is in the normal position, it is generally above its content and therefore the content of the admixing chamber Opening of the closure part under its own weight reaches the main chamber by itself. Although it is conceivable to form the walls of the admixing chamber in one piece with those of the main chamber, there is an embodiment which is particularly easy to manufacture and handle if the admixing chamber is provided in the form of a separate container inserted into the main chamber, which is preferably on the outer end face the holder for the discharge pump is sealed with a flange ring.

Ist der Verschlußteil in einer Bodenwand der vorzugsweise napfförmigen Zumischkammer vorgesehen und nimmt er insbeson­dere annähernd die gesamte Bodenwand ein, so wird zur Öff­nung der Verbindung zwischen der Zumischkammer und der Hauptkammer praktisch die gesamte zugehörige Wandung heraus­gebrochen, so daß besonders sicher gewährleistet ist, daß der gesamte Inhalt der Zumischkammer in die Hauptkammer ge­langt.If the closure part is provided in a bottom wall of the preferably cup-shaped admixing chamber and, in particular, it takes up almost the entire bottom wall, practically the entire associated wall is broken out to open the connection between the admixing chamber and the main chamber, so that it is ensured with particular certainty that the entire Contents of the admixing chamber reaches the main chamber.

Der Aufbau sowie die Handhabung der erfindungsgemäßen Aus­tragvorrichtung können noch wesentlich dadurch vereinfacht werden, daß der Verschlußteil durch die von außen in eine Kammer, insbesondere die Zumischkammer einführbare Austrag­pumpe öffenbar ist, so daß also die Austragpumpe zunächst von dem die Zumisch- und die Hauptkammer bildenden Behältnis getrennt bereitgestellt wird und zur Vermischung der Kompo­ nenten die als Ganzes von dem Behälter lösbare Austragpumpe lediglich in ihrer Betriebslage am Behälter angebracht wer­den muß.The construction and handling of the discharge device according to the invention can be significantly simplified in that the closure part can be opened by the discharge pump that can be inserted from the outside into a chamber, in particular the mixing chamber, so that the discharge pump first of all from the container forming the mixing and the main chamber is provided separately and for mixing the compo The discharge pump which can be detached as a whole only has to be attached to the container in its operating position.

Bildet dabei der Verschlußteil einen festen Bauteil mit einem Steigrohr für die Austragpumpe, das erst beim Ein­setzen der Austragpumpe in den Behälter an die Pumpe ange­schlossen wird, so braucht nicht das verhältnismäßig empfindliche und daher leicht zu beschädigende innere Ende des Steigrohres zum Öffnen des Verschlußteiles verwendet werden und es kann auch vermieden werden, daß sich der Ver­schlußteil nach dem Öffnen in unkontrollierter Lage in der Hauptkammer befindet. Des weiteren kann dadurch der Ver­schlußteil einerseits einteilig mit dem Steigrohr und ande­rerseits einteilig mit der Zumischkamme ausgebildet werden, so daß also bei einer bevorzugten Ausführungsform Zumisch­kammer, Verschlußteil und Steigrohr durch einen einzigen einstückigen Bauteil aus Kunststoff o.dgl. gebildet sind. Die einteilige Ausbildung des Verschlußteiles mit der Zu­mischkammer und die Verbindung des Verschlußteiles mit der Zumischkammer ausschließlich über die Sollbruchstelle ermög­licht auch ohne besonderen Aufwand eine äußerst dichte Aus­bildung der Zumischkammer, so daß auch im ungünstigsten Fal­le keinerlei Anteile der Zumischkomponente unbeabsichtigt in die Hauptkammer gelangen können.If the closure part forms a solid component with a riser pipe for the discharge pump, which is only connected to the pump when the discharge pump is inserted into the container, the relatively sensitive and therefore easily damaged inner end of the riser pipe need not be used to open the closure part and it can also be avoided that the closure part is in an uncontrolled position in the main chamber after opening. Furthermore, the closure part can be formed on the one hand in one piece with the riser tube and on the other hand in one piece with the admixing comb, so that in a preferred embodiment the admixing chamber, closure member and riser tube or the like by means of a single integral component made of plastic. are formed. The one-piece design of the closure part with the admixing chamber and the connection of the closure part with the admixing chamber exclusively via the predetermined breaking point enables an extremely dense formation of the admixing chamber even without special effort, so that even in the worst case, no proportions of the admixing component can get into the main chamber unintentionally.

Damit das Steigrohr keine Leitungsverbindung zwischen der Zumischkammer und der Hauptkammer herstellt, kann jeder be­liebige, von außen zu öffnende Verschluß vorgesehen sein, wobei es beispielsweise denkbar ist, eine Verschlußkappe für den Gefäßhals bzw. die Zumischkammer an ihrer Innenseite mit einem Verschlußglied für das Steigrohr zu versehen, so daß dieses Verschlußglied beim Entfernen der Verschlußkappe gleichzeitig vom Steigrohr abgezogen wird. Zum hermetischen Verschluß des Steigrohres ist es jedoch besonders vorteil­haft, wenn der Rohrverschluß des Steigrohres über eine Soll­ bruchstelle einteilig mit dem Steigrohr verbunden und so angeordnet ist, daß er durch die von außen einführbare Aus­tragpumpe öffenbar ist.So that the riser pipe does not establish a line connection between the admixing chamber and the main chamber, any closure that can be opened from the outside can be provided, it being conceivable, for example, to close a closure cap for the neck of the vessel or the admixing chamber on the inside with a closure member for the riser pipe provided so that this closure member is simultaneously removed from the riser when removing the closure cap. For the hermetic closure of the riser pipe, however, it is particularly advantageous if the pipe closure of the riser pipe is above a target Breakage is connected in one piece to the riser pipe and is arranged so that it can be opened by the discharge pump which can be inserted from the outside.

Vorteilhaft liegt der Rohrverschluß geschützt innerhalb des Steigrohres, dessen äußeres Ende zweckmäßig als Steck-Außen­hülse für die Aufnahme eines als Ansaugstutzen vorgesehenen Endstutzens des Gehäuses der Austragpumpe ausgebildet ist. Beim Einsetzen der Austragpumpe wird dadurch der Rohrver­schluß von selbst freigebrochen und somit geöffnet. Der Rohrverschluß kann daßei so ausgebildet sein, daß er aus einzelnen Segmenten besteht, die über weitere Sollbruchstel­len aneinander anschließen und sich beim Öffnen voneinander lösen, wobei diese Segmente dann jeweils eine maximale Weite haben, die kleiner als die lichte Weite des Innenkanales des Steigrohres ist, so daß mit Sicherheit gewährleistet ist, daß der freigebrochene Rohrverschluß nicht im Steigrohr stecken bleibt, sondern vollständig in die Hauptkammer fällt, wo er nicht hindert.The pipe closure is advantageously protected inside the riser pipe, the outer end of which is expediently designed as a plug outer sleeve for receiving an end piece of the discharge pump housing provided as an intake pipe. When the discharge pump is inserted, the pipe closure is broken open by itself and thus opened. The pipe closure can be designed so that it consists of individual segments which connect to one another via further predetermined breaking points and detach from one another when opened, these segments then each having a maximum width which is smaller than the clear width of the inner channel of the riser pipe, so that it is guaranteed with certainty that the broken pipe closure does not get stuck in the riser pipe, but falls completely into the main chamber, where it does not prevent.

Um eine sichere Verbindung der Austragpumpe mit dem Steig­rohr zu gewährleisten, ist es vorteilhaft, wenn die Soll­bruchstelle des Rohrverschlusses eine geringere Bruchkraft als die Sollbruchstelle des Verschlußteiles aufweist, so daß der Verschlußteil erst freigebrochen wird, wenn die Steck­verbindung zwischen Austragpumpe und Steigrohr hergestellt ist. Es ist aber auch denkbar, für das innere Ende des Steigrohres einen, beispielsweise durch den gegenüberliegen­den Boden der Hauptkammer gebildeten Anschlag vorzusehen, an welchem das innere Ende des Steigrohres in einer Lage an­schlägt, welche ihrer mit der Austragpumpe verbundenen Be­triebslage entspricht, so daß beim Einsetzen der Austragpum­pe zuerst der Verschlußteil geöffnet werden kann, wonach unter Freibrechen des Rohrverschlusses die endgültige Be­triebsverbindung zwischen Austragpumpe und Steigrohr herge­stellt wird. In diesem Fall ist das innere Ende des Steig­ rohres bzw. der Anschlag so ausgebildet, daß in der Be­triebslage das innere Ende nicht verschlossen, sondern, bei­spielsweise seitlich im Mantel zum Ansaugen des gemischten Mediums, geöffnet ist.In order to ensure a secure connection of the discharge pump with the riser pipe, it is advantageous if the predetermined breaking point of the pipe closure has a lower breaking strength than the predetermined breaking point of the closure part, so that the closure part is only broken free when the plug connection between the discharge pump and the riser pipe is established. However, it is also conceivable to provide a stop, for example formed by the opposite bottom of the main chamber, for the inner end of the riser pipe, against which the inner end of the riser pipe strikes in a position which corresponds to its operating position connected to the discharge pump, so that when inserted The discharge part of the discharge pump can first be opened, after which the final operational connection between the discharge pump and the riser pipe is established by breaking the pipe closure. In this case, the inner end of the climb Pipe or the stop formed so that the inner end is not closed in the operating position, but is open, for example laterally in the jacket for sucking in the mixed medium.

Die erfindungsgemäße Ausbildung eignet sich insbesondere für Austragvorrichtungen, bei welchen die Austragpumpe als Schubkolbenpumpe ausgebildet ist, deren Pumpenkammer vor­zugsweise über ein Einlaßventil mit dem Ansaugstutzen ver­bunden ist und deren insbesondere im Kolbenstößel liegender Austragkanal mindestens ein Auslaßventil aufweist. Diese Austragpumpe ist sowohl für flüssige wie pastöse Medien ge­eignet, kann auf genau dosierte Austragmengen justiert wer­den und ermöglicht auch einen zerstäubten bzw. gesprühten Austrag des Mischmediums. Des weiteren hat eine solche Aus­tragpumpe des wesentlichen Vorteil, daß dadurch, daß das Auslaßventil und eine ggf. in ihr vorgesehene Belüftung für die Hauptkammer im Ausgangszustand federnd geschlossen sind, im Falle empfindlicher Mischmedien deren Haltbarkeit wesent­lich erhöht werden kann.The design according to the invention is particularly suitable for discharge devices in which the discharge pump is designed as a thrust piston pump, the pump chamber of which is preferably connected to the intake port via an inlet valve, and the discharge channel of which, in particular in the piston rod, has at least one outlet valve. This discharge pump is suitable for both liquid and pasty media, can be adjusted to precisely metered discharge quantities and also enables atomized or sprayed discharge of the mixed medium. Furthermore, such a discharge pump has the essential advantage that, in the case of sensitive mixed media, the durability of the discharge valve and any ventilation provided for it in the main chamber are closed in the initial state.

Diese und weitere Merkmale von bevorzugten Weiterbildungen der Erfindung gehen auch aus der Beschreibung und den Zeich­nungen hervor, wobei die einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombinationen bei einer Ausführungsform der Erfindung und auf anderen Gebieten verwirklicht sein können. Ein Ausführungsbeispiel der Erfin­dung ist in den Zeichnungen dargestellt und wird im folgen­den näher erläutert. In den Zeichnungen zeigen:

These and further features of preferred developments of the invention are also apparent from the description and the drawings, the individual features being able to be implemented individually or in groups in the form of sub-combinations in one embodiment of the invention and in other fields. An embodiment of the invention is shown in the drawings and is explained in more detail below. The drawings show:
  • 1 is a discharge device according to the invention in view and in storage condition,
  • 2 shows a detail of the container of the discharge device according to FIG. 1 in axial section,
  • 3 shows the detail according to FIG. 2, but in the operating state of the discharge device,
  • 4 the admixing chamber of the discharge device according to FIGS. 1 to 3 in a substantially enlarged illustration and in axial section.

Wie die Fig. l bis 4 zeigen, weist eine erfindungsgemäße Austragvorrichtung l einen Speicher- bzw. Aufnahme-Behäl­ter 2 für alle zu mischenden Medienkomponenten und eine vor der Mischung und dem Austrag der Komponenten außerhalb des Behälters 2 gehaltene Austragpumpe 3 in Form einer handbetä­tigbaren Schubkolbenpumpe auf, die zum Mischen der Komponen­ten sowie zum Austrag der gemischten Komponenten gemäß Fig. 3 mit dem Behälter 2 verbunden wird.As shown in FIGS. 1 to 4, a discharge device 1 according to the invention has a storage or receiving container 2 for all media components to be mixed and a discharge pump 3 in the form of a hand-operated push piston pump which is held outside the container 2 before mixing and discharge of the components on, which is connected to the container 2 for mixing the components and for discharging the mixed components according to FIG. 3.

Der Behälter 2 weist als flaschenförmigen Außenbehälter eine Hauptkammer 4 auf, in welche als innenliegender, wesentlich kleiner-volumiger Behälter eine mit einem Steigrohr 6 inte­grierte Zumischkammer 5 eingesetzt ist. Die Zumischkammer 5 ist sowohl hinsichtlich ihrer Querschnitte als auch hin­sichtlich ihrer Länge bzw. Höhe wesentlich kleiner als die Hauptkammer 4. Zur Aufnahme der Zumischkammer 5 weist die Hauptkammer 4 an ihrer oberen Stirnwand 9 eine muffenförmige Halterung 7 auf, deren Innenweite wesentlich kleiner als die Innenweite der übrigen Hauptkammer 4 ist und die ausschließ­lich nach außen über die Stirnwand 9 vorsteht. Diese Halte­rung 7 ist nach Art eines Gefäßhalses einteilig mit allen übrigen Wandungen der Hauptkammer 4 ausgebildet und bildet auch die Befüllöffnung zur Befüllung der Hauptkammer 4 mit der Hauptkomponente. Die über ihre Länge im wesentlichen durchgehend konstante Innenweite der Halterung 7 ist nur geringfügig größer als die Außenumfangsweite der Zumischkam­ mer 5, die annähernd über ihre gesamte Höhe konstante Quer­schnitte aufweist und mit geringem Spaltabstand derart in die Halterung 7 eingreift, daß ihr inneres Ende nach innen über die Stirnwand 9 vorsteht, jedoch ein großer bzw. ihr größter Teil innerhalb der Halterung 7 liegt. Die Zumisch­kammer 5 ist somit nach Art einer einfachen Steckverbindung mit der Hauptkammer 4 verbunden und in ihrer zur Mittelachse l0 der Austragvorrichtung l achsgleichen Lage gegenüber der Halterung 7 zentriert. Am äußeren Ende weist die Zumischkam­mer 5 einen über ihren Außenumfang vorstehenden Flanschring ll auf, der gleichen Außenquerschnitt wie das zugehörige Ende der Halterung 7 aufweist und an deren Stirnfläche l2 unter Zwischenlage einer Ringdichtung l3 anliegt. Benachbart zum Flanschring ll weist die Zumischkammer 5 zur Zentrierung gegenüber der Halterung 7 einen in der Außenweite erweiter­ten Abschnitt auf. Die Boden-Wandung l5 der napfförmigen und an ihrem äußeren Ende auf voller Weite offenen Zumischkammer 5 ist einteilig mit der Mantelwandung l4 der Zumischkammer 5 sowie mit dem Steigrohr 6 ausgebildet, das annähernd über seine gesamte Länge konstante Querschnitte hat. Ein in die Zumischkammer 5 ragender Längsabschnitt des Steigrohres 6 ist kürzer als die Zumischkammer 5, so daß das Ende dieses Längsabschnittes zwischen der Wandung l5 und dem offenen Ende der Zumischkammer 5 innerhalb von dieser vorgesehen ist. Der andere Längsabschnitt ragt von der Boden-Wandung l5 in die Hauptkammer 4, hat jedoch im Zustand gemäß Fig. 2 von deren gegenüberliegender Bodenwand l6 einen verhältnismäßig großen Abstand. In der Ebene der Boden-Wandung l5 steht über den Außenumfang des Steigrohres 6 ringbundförmig ein Ver­schlußteil l7 vor, der wenigstens einen zentralen Teil der Boden-Wandung l5 bildet und mit dem an seinen Außenumfang anschließenden Teil der Boden-Wandung bzw. der Mantelwand l4 über eine Sollbruchstelle l8 einteilig verbunden ist. Die durch eine beträchtliche Dickenschwächung der Wandung der Zumischkammer 5 gebildete Sollbruchstelle l8 ist durch min­destens eine ringförmig um die Mittelachse l0 geschlossene Kerbnut an der Innenseite oder an der Außenseite der zugehö­rigen Wand der Zumischkammer 5 definiert, wobei im darge­stellten Ausführungsbeispiel derartige Kerbnuten l9, 20 im wesentlichen deckungsgleich und von gleichem Querschnitt bzw. gleicher Tiefe an beiden Seiten vorgesehen sind. Die Sollbruchstelle l8 kann auch eine Weite aufweisen, die we­nigstens an die Innenweite der Zumischkammer 5 angenähert ist. Die Außenweite des Steigrohres 6, insbesondere von des­sen in die Zumischkammer 5 ragenden Teil, ist gegenüber der Innenweite der Zumischkammer 5 wesentlich kleiner, bei­spielsweise nur etwa halb so groß.The container 2 has, as a bottle-shaped outer container, a main chamber 4, into which an admixing chamber 5 integrated with a riser pipe 6 is inserted as an inner, substantially smaller-volume container. The admixing chamber 5 is substantially smaller than the main chamber 4 both in terms of its cross sections and in terms of its length or height. To accommodate the admixing chamber 5, the main chamber 4 has a sleeve-shaped holder 7 on its upper end wall 9, the inside width of which is considerably smaller than the inside width the rest of the main chamber 4 and which only projects outwards beyond the end wall 9. This holder 7 is formed in one piece in the manner of a vessel neck with all the other walls of the main chamber 4 and also forms the filling opening for filling the main chamber 4 with the main component. The essentially constant internal width of the holder 7 over its length is only slightly larger than the outer circumferential width of the admixture mer 5, which has approximately constant cross sections over its entire height and engages with a small gap distance in the holder 7 such that its inner end protrudes inward beyond the end wall 9, but a large or its largest part is within the holder 7. The admixing chamber 5 is thus connected to the main chamber 4 in the manner of a simple plug-in connection and is centered relative to the holder 7 in its position which is axially identical to the central axis l0 of the discharge device l. At the outer end, the admixing chamber 5 has a flange ring 11 projecting over its outer circumference, which has the same outer cross section as the associated end of the holder 7 and bears against the end face 12 thereof with an intermediate ring seal 13. Adjacent to the flange ring II, the admixing chamber 5 has a section which is widened in the outside width for centering relative to the holder 7. The bottom wall l5 of the cup-shaped admixing chamber 5, which is open at its outer end to its full width, is formed in one piece with the jacket wall l4 of the admixing chamber 5 and with the riser pipe 6, which has constant cross sections over its entire length. A longitudinal section of the riser tube 6 projecting into the admixing chamber 5 is shorter than the admixing chamber 5, so that the end of this longitudinal section is provided between the wall 15 and the open end of the admixing chamber 5. The other longitudinal section protrudes from the bottom wall l5 into the main chamber 4, but is in the state according to FIG. 2 from its opposite bottom wall l6 a relatively large distance. In the plane of the bottom wall l5, a closure part l7, which forms at least a central part of the bottom wall l5 and projects with the part of the bottom wall or the jacket wall l4 adjoining its outer circumference, projects in a ring collar over the outer circumference of the riser tube 6 a predetermined breaking point l8 is connected in one piece. The predetermined breaking point 18 formed by a considerable weakening of the thickness of the wall of the admixing chamber 5 is closed by at least one ring around the central axis 10 Notch groove defined on the inside or on the outside of the associated wall of the admixing chamber 5, such notches 19, 20 being substantially congruent and of the same cross-section or the same depth being provided on both sides in the exemplary embodiment shown. The predetermined breaking point 18 can also have a width which is at least approximated to the inner width of the admixing chamber 5. The outside width of the riser pipe 6, in particular of its part projecting into the admixing chamber 5, is considerably smaller than the inside width of the admixing chamber 5, for example only about half as large.

Die Verschlußkappe 8 übergreift die Halterung 7 an der Au­ßenseite und ist in ihrer Verschlußlage gegenüber der Halte­rung 7 durch geeignete Sicherungsglieder gesichert. Im dar­gestellten Ausführungsbeispiel sind die Sicherungsglieder 2l durch ein Außengewinde an der Halterung 7 und ein Innenge­winde am Mantel der Verschlußkappe 8 gebildet. Sie können aber auch durch die Glieder eines Schnappverschlusses, eines Springverschlusses oder durch ein gesondertes, nur durch Zerstörung lösbares und als Versiegelung dienendes Siche­rungsglied gebildet sein. Die ebene Stirnwand der Verschluß­kappe 8 liegt abgedichtet am Flanschring ll an und preßt diesen gegen die Halterung 7, so daß durch die Verschlußkap­pe 8 einerseits die Hauptkammer 4 und die Zumischkammer 5 gegeneinander und andererseits jede einzelne Kammer für sich nach außen verschlossen ist.The closure cap 8 engages over the holder 7 on the outside and is secured in its closed position relative to the holder 7 by suitable securing members. In the illustrated embodiment, the securing members 2l are formed by an external thread on the holder 7 and an internal thread on the jacket of the closure cap 8. However, they can also be formed by the members of a snap lock, a spring lock or by a separate securing member that can only be removed by destruction and serves as a seal. The flat end wall of the closure cap 8 lies in a sealed manner on the flange ring 11 and presses it against the holder 7, so that the main chamber 4 and the admixing chamber 5 are closed to one another by the closure cap 8 and each individual chamber is closed to the outside on the other hand.

Nach Abnehmen der Verschlußkappe 8 ist die Zumischkammer 5 an ihrer Oberseite geöffnet, wobei die Zumischkammer 5 nur über einen Teil oder annähernd über ihre gesamte Höhe mit der zugehörigen Zumischkomponente gefüllt sein kann. Auch in diesem Zustand bleibt die Hauptkammer 4 nach außen ver­schlossen, d.h., daß auch in diesem Zustand die Zumischkam­mer 5 gegenüber der Hauptkammer 4 verschlossen ist. Dies wird durch einen Rohrverschluß 22 erreicht, der in dem Steigrohr 6 innerhalb der Zumischkammer 5 und zwar relativ nahe benachbart zum zugehörigen Ende des Steigrohres 6 vor­gesehen ist. Der scheiben- bzw. membranförmige Rohrverschluß 22 ist einteilig mit dem Steigrohr 6 ausgebildet und schließt an die Begrenzung von dessen Innenkanal über eine ringförmige Sollbruchstelle 23 an. Diese Sollbruchstelle 23, die ebenfalls durch eine oder zwei Kertnuten gebildet sein kann, liegt so, daß nach Freibrechen des Rohrverschlusses 22 praktisch keinerlei Grat über die Begrenzungsfläche des In­nenkanales 24 vorsteht. Der Rohrverschluß 22 liegt innerhalb eines für die Steckverbindung mit einem Ansaugstutzen 27 der Austragpumpe 3 vorgesehenen Anschlusses 25, der durch das als Steck-Außenhülse 26 ausgebildete zugehörige Ende des Steigrohres 6 gebildet ist. Der äußere Endabschnitt dieser Außenhülse 26 weist eine gegenüber dem übrigen Steigrohr 6 sowie gegenüber dem Außenumfang des Ansaugstutzens 27 ge­ringfügig größere Innenweite auf, wobei dieser Abschnitt über einen spitzwinklig kegelstumpfförmig verjüngten Zwi­schenabschnitt 28 in den anschließenden, engeren Innenkanal 24 übergeht und der Rohrverschluß 22 am Übergang zwischen dem Zwischenabschnitt 28 und dem übrigen Innenkanal 24 liegt. Die Länge des weiteren Endabschnittes der Außenhülse 26 liegt in der Größenordnung etwa von der Hälfte der Länge des Ansaugstutzens 27, so daß dieser annähernd mit der Hälf­te seiner Länge in den anschließenden Innenkanal 24 eingrei­fen kann, dessen Innenquerschnitt an den Außenquerschnitt des Ansaugstutzens 27 so angepaßt ist, daß dieser abgedich­tet eingreift. Nach dem Abnehmen der Verschlußkappe 8 wird die Austragpumpe 3 in die Zumischkammer 5 derart eingesetzt, daß der Ansaugstutzen 27 in die Außenhülse 26 eintaucht. Nach Anschlagen der Endfläche des Ansaugstutzens 27 an dem Rohrverschluß 22 wird dieser durch weiteres Einführen der Austragpumpe 3 freigebrochen, so daß der Ansaugstutzen 27 vollends in seine Betriebslage gemäß Fig. 3 in das Steigrohr 6 eindringt. Bei Erreichen dieser Lage schlägt die Austrag­pumpe 3 mit einem Endanschlag 29 an der zugehörigen Stirn­ fläche des Steigrohres 6 an, wobei dieser Endanschlag 29 durch eine an den Ansaugstutzen 27 anschließende kegel­stumpfförmige Ringschulter 29 gebildet ist, die durch Ein­greifen in den Innenrand der Außenhülse 26 zur weiteren Ab­dichtung der Verbindung zwischen Austragpumpe 3 und Steig­rohr 6 beiträgt. In dieser Lage hat die Austragpumpe 3 noch nicht ihre Betriebsstellung gegenüber dem Behälter 2 er­reicht, in welcher sie mit einem über die Außenseite ihres Gehäuses vorstehenden Ringflansch 30, der zweckmäßig durch eine äußere Zylinderdeckelkappe des Gehäuses gebildet ist, unter Zwischenlage einer Ringdichtung 3l an der äußeren Stirnfläche des Flanschringes ll anliegt und dadurch die Zumischkammer 5 verschließt. Zur vollständigen Überführung in die Betriebslage wird die Austragpumpe 3 weiter in die Zumischkammer 5 hineingedrückt, wobei sie über den Endan­schlag 29 das klemmend mit ihr verbundene Steigrohr 6 unter Brechen der Sollbruchstelle l8 mitnimmt. Dadurch wird der Verschlußteil l7 vollständig von der Zumischkammer 5 gelöst, so daß um das Steigrohr 6 eine ringförmige Übertrittsöffnung 32 von der Zumischkammer 5 zur Hauptkammer 4 freigelegt wird. Die in der Zumischkammer 5 befindliche Zumischkompo­nente fließt selbsttätig in die Hauptkammer 4, in welcher sie mit der dort befindlichen Hauptkomponente zusammenge­bracht und ggf. durch Schütteln vermischt wird. Diese Durch­mischung wird noch durch die in die Hauptkammer 4 ragende Zumischkammer 5 und den ringtellerförmigen Verschlußteil l7 gefördert, da diese Teile zur Strömungsverwirbelung bei­tragen.After the closure cap 8 has been removed, the admixing chamber 5 is open at its top, the admixing chamber 5 being able to be filled with the associated admixing component only over part or almost its entire height. In this state, too, the main chamber 4 remains closed to the outside, ie the admixing chamber 5 is also closed in relation to the main chamber 4 in this state. This is achieved by a pipe closure 22 which in the Riser pipe 6 is provided within the admixing chamber 5, namely relatively close to the associated end of the riser pipe 6. The disk-shaped or membrane-shaped pipe closure 22 is formed in one piece with the riser pipe 6 and connects to the boundary of its inner channel via an annular predetermined breaking point 23. This predetermined breaking point 23, which can also be formed by one or two notches, is such that after the pipe closure 22 has been broken free, practically no burr protrudes beyond the boundary surface of the inner channel 24. The pipe closure 22 lies within a connection 25 provided for the plug-in connection with an intake port 27 of the discharge pump 3, which is formed by the associated end of the riser pipe 6 designed as a plug-in outer sleeve 26. The outer end section of this outer sleeve 26 has a slightly larger inner width than the remaining riser pipe 6 and the outer circumference of the intake manifold 27, this section passing over an intermediate section 28 tapering in the shape of a truncated cone into the subsequent, narrower inner channel 24 and the pipe closure 22 at the transition between the intermediate section 28 and the remaining inner channel 24. The length of the further end portion of the outer sleeve 26 is of the order of about half the length of the intake manifold 27, so that it can engage approximately half its length in the adjoining inner channel 24, the internal cross section of which is adapted to the external cross section of the intake manifold 27 that this engages sealed. After the closure cap 8 has been removed, the discharge pump 3 is inserted into the admixing chamber 5 in such a way that the suction nozzle 27 dips into the outer sleeve 26. After striking the end face of the intake manifold 27 on the pipe closure 22, this is broken open by further insertion of the discharge pump 3, so that the intake manifold 27 completely penetrates into the riser pipe 6 into its operating position according to FIG. 3. When this position is reached, the discharge pump 3 strikes with an end stop 29 on the associated forehead Surface of the riser pipe 6, this end stop 29 being formed by a frustoconical annular shoulder 29 adjoining the intake manifold 27, which, by engaging in the inner edge of the outer sleeve 26, contributes to further sealing the connection between discharge pump 3 and riser pipe 6. In this position, the discharge pump 3 has not yet reached its operating position in relation to the container 2, in which it has an annular flange 30 projecting beyond the outside of its housing, which is expediently formed by an outer cylinder cover cap of the housing, with the interposition of an annular seal 3l on the outer End face of the flange ring 11 abuts and thereby closes the admixing chamber 5. For complete transfer into the operating position, the discharge pump 3 is pressed further into the admixing chamber 5, taking the riser pipe 6 connected to it in a clamped manner via the end stop 29, breaking the predetermined breaking point 18. As a result, the closure part 17 is completely released from the admixing chamber 5, so that an annular transition opening 32 from the admixing chamber 5 to the main chamber 4 is exposed around the riser pipe 6. The admixing component located in the admixing chamber 5 flows automatically into the main chamber 4, in which it is brought together with the main component located there and mixed if necessary by shaking. This mixing is further promoted by the admixing chamber 5 projecting into the main chamber 4 and the ring-shaped closure part 17, since these parts contribute to the swirling of the flow.

Zur Sicherung der Austragpumpe 3 dient eine die Verschluß­kappe 8 ersetzende Muffe, die zweckmäßig durch dieselben Sicherungsglieder 2l der Halterung 7 wie die Verschlußkappe 8 gesichert, also im dargestellten Ausführungsbeispiel als Schraubmuffe 8ʹ ausgebildet ist, mit welcher die Austrag­pumpe 3 sicher festgespannt werden kann. Es ist aber auch denkbar, die am Ringflansch 30 angreifende, die Halterung 7 am Außenumfang umgebende Muffe durch andere Sicherungsglie­der als die Verschlußkappe 8 gegenüber der Halterung 7 zu sichern, beispielsweise dadurch, daß sie nach Art eines Schnappverschlusses aufgesprengt ist.To secure the discharge pump 3 is a closure cap 8 replacing sleeve, which is expediently secured by the same securing members 2l of the holder 7 as the closure cap 8, that is, in the exemplary embodiment shown is designed as a screw sleeve 8 'with which the discharge pump 3 can be securely clamped. However, it is also conceivable for the holder 7, which acts on the ring flange 30 to secure the surrounding sleeve on the outer circumference by means of securing members other than the closure cap 8 relative to the holder 7, for example in that it is blown open in the manner of a snap closure.

Die Austragpumpe 3 ist im dargestellter Ausführungsbeispiel als Schubkolbenpumpe ausgebildet, deren in die Zumischkammer 5 ragendes, zum Ansaugstutzen 27 im Außendurchmesser mehr­fach abgesetzt reduziertes Zylindergehäuse über seine gesam­te Länge mit Abstand vom Innenumfang der Zumischkammer 5 liegt. Die Austragpumpe 3 weist eine im Zylindergehäuse 33 verschiebbare Kolbeneinheit 34 mit einer elastischen Kolben­manschette 35 auf, die an ihren äußerer Ende einteilig mit einer elastisch federnden Stauchhülse 36 ausgebildet ist. Die Kolbenmanschette 35 und die Stauchhülse 36 sind am Au­ßenumfang eines Kolbenstößels 37 angeordnet, welcher von einem zu seinem außerhalb des Pumpengehäuses liegenden Ende führenden Austragkanal 38 durchsetzt ist. Die Kolbenman­schette 35 bildet im Übergangsbereich zur Stauchhülse 36 den äußeren, ringförmigen Ventilschließteil eines Auslaßventiles 39, dessen Ventilsitz am Kolbenstößel 37 vorgesehen ist. Die Kolbenmanschette 35 kann einschließlich des Ventilschließ­teiles unter rückfedernder Stauchung der Stauchhülse 36 ge­genüber dem Kolbenstößel 37 entgegen der Richtung des Pump­hubes bewegt werden, wodurch das Auslaßventil 39 öffnet. Diese Bewegung kann entweder gegen Ende des Pumphubes durch Anschlag der Kolbenmanschette 35 an einer Innenschulter des Zylindergehäuses 33 zwangsläufig oder durckabhängig durch einen entsprechenden Überdruck in der Pumpenkammer erfolgen. Zwischen der Pumpenkammer und dem Ansaugstutzen 27 weist die Austragpumpe 3 ein Einlaßventil 40 in Form eines Kugelventi­les auf, welches bei Überdruck in der Pumpenkammer, also während des Pumphubes, schließt.The discharge pump 3 is designed in the exemplary embodiment shown as a thrust piston pump, the cylinder housing of which projects into the admixing chamber 5 and is reduced in the outer diameter several times over the entire length of the admixing chamber 5. The discharge pump 3 has a piston unit 34 which can be displaced in the cylinder housing 33 and has an elastic piston sleeve 35 which is formed in one piece at its outer end with an elastically resilient compression sleeve 36. The piston sleeve 35 and the compression sleeve 36 are arranged on the outer circumference of a piston tappet 37 which is penetrated by a discharge channel 38 leading to its end located outside the pump housing. In the transition area to the compression sleeve 36, the piston sleeve 35 forms the outer, annular valve closing part of an outlet valve 39, the valve seat of which is provided on the piston tappet 37. The piston sleeve 35, including the valve closing part, can be moved against the direction of the pump stroke, with the compression sleeve 36 springing back against the piston tappet 37, as a result of which the outlet valve 39 opens. This movement can take place either towards the end of the pump stroke by abutment of the piston sleeve 35 on an inner shoulder of the cylinder housing 33 or, depending on the pressure, through a corresponding excess pressure in the pump chamber. Between the pump chamber and the intake port 27, the discharge pump 3 has an inlet valve 40 in the form of a ball valve, which closes when there is excess pressure in the pump chamber, that is to say during the pumping stroke.
