Description

Die Erfindung betrifft eine Austragvorrichtung für Medien, mit einem Speicher, dem eine mit einer Handhabe betätigbare Austragpumpe zugeordnet ist, welche an einem am Speicher anzuordnenden Pumpen­gehäuse mit einem den Speicher mit einer Pumpenkam­mer verbindenden Saugkanal und einem von der Pumpen­kammer zu einer Auslaßöffnung führenden Auslaßkanal versehen ist.The invention relates to a discharge device for media, with a storage device, to which a discharge pump that can be actuated with a handle is assigned, which is provided on a pump housing to be arranged on the storage device with a suction channel connecting the storage device to a pump chamber and an outlet channel leading from the pump chamber to an outlet opening .

Besonders pharmazeutische und kosmetische, aber auch technische und ähnliche Medien, können im Anwendungszustand aus zwei oder mehr Komponenten bestehen, die aus Gründen einer einzuhaltenden Reaktionszeit, einer möglichst frischen und daher wirksamen Zubereitung oder weil sie im gemischten Zustand zu Veränderungen, beispielsweise geringerer Haltbarkeit, neigen, möglichst erst kurz vor Ge­brauch bzw. beim Gebrauch gemischt werden sollten. Daher werden solche Mischmedien in der Regel ge­trennt voneinander in gesonderten Gefäßen bereit­gestellt. Entweder müssen die Komponenten vor dem Gebrauch gemischt oder bei pharmazeutischen und kosmetischen Zubereitungen gelegentlich unmittel­bar nacheinander appliziert und dadurch zur Ver­bindung bzw. Mischung gebracht werden. Hierzu be­darf es einiger Geschicklichkeit und auch hoher Sorgfalt, wenn es darauf ankommt, daß die Kompo­nenten in einem genauen Mengenverhältnis mitein­ander anzuwenden sind.Especially pharmaceutical and cosmetic, but also technical and similar media can consist of two or more components in the application state, which are used for reasons of a reaction time to be observed, a preparation that is as fresh and therefore effective as possible or because in the mixed state they cause changes, for example less Shelf life, tend to be mixed just before use or when in use. Such mixed media are therefore usually provided separately from each other in separate vessels. Either the components have to be mixed before use or, in the case of pharmaceutical and cosmetic preparations, occasionally applied one after the other and thereby brought together or mixed. This requires some skill and also great care when it comes down to the fact that the components are to be used in an exact quantity ratio.

Der Erfindung liegt die Aufgabe zugrunde, eine Aus­tragvorrichtung der genannten Art zu schaffen, mit welcher mindestens zwei in Verbindung miteinander anzuwendende Komponenten zeitlich aufeinander ge­nau abgestimmt ausgebracht und durch einfache Hand­betätigung in Verbindung miteinander gebracht wer­den können, ohne daß die Medien hierzu im Speicher einem Druck ausgesetzt werden müssen.The invention has for its object to provide a discharge device of the type mentioned, with which at least two components to be used in conjunction with each other can be applied precisely in time and brought into connection with one another by simple manual operation, without exposing the media to pressure in the memory Need to become.

Diese Aufgabe wird bei einer Austragvorrichtung der eingangs beschriebenen Art gemäß der Erfindung dadurch gelöst, daß für mindestens zwei Medien - ­Komponenten gesonderte Speicher mit gesonderten Austragpumpen vorgesehen sind und mindestens zwei Austragspumpen mit einer einzigen Handhabe gemein­sam betätigbar sind. Dadurch werden einerseits die Komponenten in ihren noch nicht verwendeten ge­speicherten Vorratsmengen ständig getrennt vonein­ander gehalten und andererseits können die beiden Komponenten durch Betätigung nur einer einzigen Handhabe in einem relativ genau bestimmbaren Mengen­ verhältnis in Verbindung miteinander gebracht bzw. ausgetragen werden. Austragpumpen der genannten Art können nämlich als verhältnismäßig genau dosierende Dosierpumpen ausgebildet sein, die mit jedem Pump­takt eine genau reproduzierbare Menge an Medium fördern, wobei die gemeinsam zu betätigenden Aus­tragpumpen je nach den Erfordernissen gleiche oder unterschiedliche Fördermengen aufweisen können.This object is achieved in a discharge device of the type described at the outset according to the invention in that separate stores with separate discharge pumps are provided for at least two media components and at least two discharge pumps can be actuated together with a single handle. As a result, on the one hand, the components in their unused stored quantities are kept separate from one another, and on the other hand, the two components can be operated in a relatively precisely determinable amount by actuating only a single handle relationship in connection with each other or carried out. Discharge pumps of the type mentioned can namely be designed as relatively precisely metering dosing pumps which deliver a precisely reproducible amount of medium with each pump cycle, the discharge pumps to be operated together having the same or different delivery rates depending on the requirements.

Es ist denkbar, die Anordnung so vorzusehen, daß die Austragpumpen nach Art einer Registersteuerung un­mittelbar aufeinander folgend, also nacheinander in Stufen fördern, so daß die zugehörigen Komponenten nacheinander ausgetragen werden. Besonders vorteil­haft ist es jedoch, wenn die Ausbildung so vorge­sehen ist, daß bei Betätigung der Handhabe mindestens zwei von dieser betätigbare Austragpumpen gleichzeitig bzw. simultan fördern, so daß die Komponenten unmittel­bar beim Austragen miteinander gemischt werden können. Hierzu führen die Auslaßkanäle mindestens zweier Austragpumpen zweckmäßig zu einer Komponenten-Misch­zone, die vorzugsweise in unmittelbarer Nähe wenig­stens einer Auslaßöffnung liegt.It is conceivable to provide the arrangement in such a way that the discharge pumps, in the manner of a register control, deliver directly in succession, that is to say in stages, so that the associated components are discharged one after the other. However, it is particularly advantageous if the design is provided such that when the handle is actuated, at least two discharge pumps which can be actuated by the latter deliver simultaneously or simultaneously, so that the components can be mixed with one another immediately during discharge. For this purpose, the outlet channels of at least two discharge pumps expediently lead to a component mixing zone, which is preferably in the immediate vicinity of at least one outlet opening.

Ist mindestens eine Komponente von der Art, daß ihr eine unmittelbare Berührung mit Luft vor Vermischung mit der anderen Komponente abträglich ist, so ist die Mischzone vorteilhaft in Austragrichtung vor der Auslaßöffnung, insbesondere unmittelbar benachbart zum Eintritt in eine Auslaßdüse vorgesehen, wobei vorzugsweise beide Auslaßkanäle in einen gemeinsamen Endkanal übergehen, der seinerseits in die bei­spielsweise am Umfang und/oder im Bereich ihrer hin­teren Stirnseite mit schraubenwendelförmigen oder spiralnutartigen Drallkanälen versehene Auslaßdüse mündet. Dadurch sind ab etwa dem Bereich, in welchem die Komponenten zusammengebracht werden und vor der Auslaßöffnung Wirbelzonen bzw. Wirbelkammern gebil­det, in welchen die zusammengebrachten Komponenten intensiv unter Ausnutzung des Förderdruckes vermischt werden.If at least one component is such that direct contact with air before mixing with the other component is detrimental to it, the mixing zone is advantageously provided in the discharge direction in front of the outlet opening, in particular immediately adjacent to the inlet into an outlet nozzle, preferably both outlet channels in pass over a common end channel, which in turn is provided in the outlet nozzle, which is provided, for example, on the periphery and / or in the region of its rear end face with helical or spiral groove-like swirl channels flows. As a result, from around the area in which the components are brought together and vortex zones or vortex chambers are formed in front of the outlet opening, in which the brought-together components are mixed intensively using the delivery pressure.

Nicht nur bei aufeinanderfolgendem Austrag der Kompo­nenten, sondern auch bei gleichzeitigem Austrag kann es aber auch aufgrund spezifischer Eigenschaften die­ser Komponenten vorteilhaft sein, wenn die Komponenten erst außerhalb der Austragvorrichtung zusammengebracht werden, so daß das Verbleiben vermischter Komponenten in der Austragvorrichtung völlig ausgeschlossen ist. In diesem Fall liegt die Mischzone in Austragrichtung nach der Auslaßöffnung, insbesondere außerhalb der Aus­tragvorrichtung im Freien. Je nach Eigenart des Mediums kann es dabei zweckmäßig sein, daß die austretenden Komponenten an benachbarten Stellen gesondert aufge­tragen und dann beispielsweise durch Verreiben mitein­ander vermischt werden. Die Komponenten können aber auch in diesem Fall vor Erreichen der Auftragstelle außerhalb der Austragvorrichtung sehr gut gemischt werden, da handbetätigbare Pumpen bei Verwendung ent­sprechend gestalteter Auslaßdüsen besonders vorteil­haft zur Erzeugung eines feinsten Sprühnebel-Strahles geeignet sind. Sind die Auslaßöffnungen so zueinander ausgerichtet, daß sich die aus ihnen austretenden Strahle in nicht allzu weiter Entfernung von den Aus­laßdüsen überschneiden, so ist insbesondere bei Er­zeugung von Sprühnebel-Strahlen infolge der feinsten Tröpfchenverteilung des Mediums in dieser durch Über­schneidung gebildeten Sprühnebelzone eine sehr inten­sive Durchmischung in äußerst kurzem zeitlichem Ab­ stand vor dem Auftreffen auf der Auftragstelle zu erzielen. Dies kann in besonderem Maße bei pharma­zeutischen Wirkstoffen von großem Vorteil sein, da diese häufig eine umso bessere Wirksamkeit haben, je frischer sie vor der Anwendung angemischt sind.Not only with successive discharge of the components, but also with simultaneous discharge, it can also be advantageous due to the specific properties of these components if the components are first brought together outside the discharge device, so that the remaining mixed components in the discharge device are completely excluded. In this case, the mixing zone is in the discharge direction after the outlet opening, in particular outside of the discharge device outdoors. Depending on the nature of the medium, it may be expedient for the emerging components to be applied separately at adjacent locations and then mixed with one another, for example by rubbing. In this case, too, the components can be mixed very well before reaching the application point outside the discharge device, since hand-operated pumps are particularly advantageously suitable for producing a very fine spray jet when using appropriately designed outlet nozzles. If the outlet openings are aligned with each other so that the jets emerging from them overlap not too far from the outlet nozzles, particularly when spray mist jets are generated due to the finest droplet distribution of the medium in this spray mist zone formed by overlapping, there is a very intensive mixing extremely short time stood before hitting the job site. This can be of particular advantage in the case of active pharmaceutical ingredients, since the more effective they are, the fresher they are mixed before use.

Zur Erzielung einer möglichst kompakten und leicht handzuhabenden Bauweise ist die Austragöffnung bzw. sind die Austragöffnungen unmittelbar an der Hand­habe vorgesehen, wobei sie etwa bündig in einer Wandung der Handhabe liegen oder am Ende eines über den Außenumfang der Handhabe vorstehenden Ansatzes, wie eines Schnabels, vorgesehen sein können.In order to achieve the most compact and easy-to-use design, the discharge opening or the discharge openings are provided directly on the handle, being approximately flush in a wall of the handle or provided at the end of an extension projecting beyond the outer circumference of the handle, such as a beak could be.

Vor allem wenn baulich gesonderte und erst durch die Austragvorrichtung räumlich einander zugeordnete Speicher verwendet werden, ist es vorteilhaft, wenn zur Erzielung einer möglichst großen Stabilität der Gesamtvorrichtung die Handhabe mindestens zwei neben­einanderliegende Austragpumpen miteinander,insbeson­dere nach Art einer Brücke, verbindet und vorzugs­weise einteilig ausgebildet ist. Dies wird noch wei­ter verbessert, wenn die Handhabe im Bereich einer gemeinsamen brückenartigen Anschlußkappe für die insbesondere flaschenförmigen Speicher liegt und vorzugsweise mit einem Wandungsrand in einen ihrer Grundform entsprechenden Ringsteg der Anschlußkappe eingreift, so daß die beiden gesonderten, flaschen­förmigen und ggf. gleichen Speicher nicht unmittel­bar in Berührung oder mechanisch fester Verbindung miteinander stehen müssen, sondern mit geringem Ab­stand auf Lücke benachbart zueinander angeordnet werden können.Especially if structurally separate and only spatially allocated to each other by the discharge device are used, it is advantageous if, in order to achieve the greatest possible stability of the overall device, the handle connects at least two discharge pumps lying next to one another, in particular in the manner of a bridge, and is preferably constructed in one piece . This is further improved if the handle lies in the area of a common bridge-like connection cap for the bottle-shaped memory in particular and preferably engages with a wall edge in an annular web of the connection cap corresponding to its basic shape, so that the two separate, bottle-shaped and possibly the same memory do not immediately must be in contact or mechanically fixed connection with each other, but can be arranged close to each other with a small gap.

In weiterer Ausgestaltung der Erfindung weist die Anschlußkappe jedoch gesonderte Halterungen für die Austragpumpen sowie ggf. gesonderte Verbindungskappen für Flaschenhälse der etwa parallel unmittelbar be­nachbart zueinander stehenden Speicher auf, wobei auch die Anschlußkappe einteilig ausgebildet sein kann. Die Flaschenhälse können durch einfache, druck­dichte Schnappverbindungen gesondert oder gemeinsam in Eingriff mit den Verbindungskappen gebracht werden, was insbesondere vorteilhaft ist, wenn die beiden Speicher durch einen einzigen formfesten, beispiels­weise einteiligen Bauteil gebildet sind. Bei geson­derter Ausbildung der Speicher können die Flaschen­hälse aber auch über Gewinde in Eingriff mit den Ver­bindungskappen gebracht werden, da die Speicher un­abhängig voneinander in die Verbindungskappen einge­schraubt werden können.In a further embodiment of the invention, however, the connection cap has separate holders for the Discharge pumps and, if necessary, separate connection caps for bottle necks of the approximately parallel immediately adjacent storage tanks, wherein the connection cap can also be formed in one piece. The bottle necks can be brought into engagement with the connection caps separately or simply together by simple, pressure-tight snap connections, which is particularly advantageous if the two stores are formed by a single dimensionally stable, for example one-piece component. With a separate design of the storage, the bottle necks can also be brought into engagement with the connecting caps via threads, since the storage can be screwed into the connecting caps independently of one another.

Zur weiteren Erhöhung der Festigkeit der Gesamtvor­richtung und zur Vermeidung von eventuell zu Lecks führenden Belastungen der Verbindung der Austragvor­richtung mit den Speichern, kann nach der Herstellung dieser Verbindung eine zusätzliche Halterungsbrücke an den Speichern angebracht werden, die vorzugsweise durch eine flache, die Speicher im Bodenbereich eng umschließende Steckkappe gebildet ist.In order to further increase the strength of the overall device and to avoid possible loads on the connection of the discharge device to the accumulators which may lead to leaks, an additional mounting bridge can be attached to the accumulators after the production of this connection, which is preferably narrow due to a flat, the accumulator in the bottom area enclosing plug cap is formed.

Die erfindungsgemäße Ausbildung ist insbesondere für solche Austragvorrichtungen geeignet, bei denen die Austragpumpen nicht als Balg-, elastische Kammer - ­oder ähnliche Pumpen, sondern als Schubkolbenpumpen ausgebildet sind, da diese wesentliche Vorteile haben. Sie können mit hohen Förderdrücken betrieben werden, eignen sich zur sehr genauen Dosierung, erlauben einen luftdichten Abschluß sowohl des Pumpengehäuses als auch des Speichers bei Ausgangsstellung der Pumpe, gewährleisten eine hohe Austraggeschwindigkeit und sind sowohl zum tropfenweisen als auch zum spritz­ strahlartigen oder sprühstrahlartigen Austrag ge­eignet; ferner können sie sowohl für flüssige wie auch für pastöse bzw. breiige oder ähnlich fließ­fähige Medien verwendet werden. Zweckmäßig weist die jeweilige Austragpumpe ein vom Druck in der Pumpen­kammer oder in Abhängigkeit von der Kolbenstellung des Pumpkolbens gesteuertes Auslaßventil auf, das somit die Verbindung von der Pumpenkammer zum Aus­laßkanal erst öffnet, wenn in der Pumpenkammer bei geschlossenem Zustand eines die Verbindung zum Spei­cher herstellenden Saugventiles ein verhältnismäßig hoher Druck aufgebaut ist.The design according to the invention is particularly suitable for discharge devices in which the discharge pumps are not designed as bellows, elastic chamber or similar pumps, but as thrust piston pumps, since these have significant advantages. They can be operated at high delivery pressures, are suitable for very precise dosing, allow an airtight seal for both the pump housing and the reservoir when the pump is in the initial position, ensure a high discharge rate and are suitable for both drop by drop and spray suitable for jet-like or spray-like discharge; furthermore, they can be used both for liquid and for pasty or pulpy or similarly flowable media. The respective discharge pump expediently has an outlet valve which is controlled by the pressure in the pump chamber or as a function of the piston position of the pump piston and which therefore only opens the connection from the pump chamber to the outlet channel when a suction valve which connects to the accumulator is in the closed state in the pump chamber relatively high pressure is built up.

Wie die Fig. 1 bis 4 zeigen, weist eine erfindungs­gemäße Austragvorrichtung 1 zwei fläschchenförmige, im wesentlichen zylindrische Speicher 2 zur Vorratshal­tung von Medien-Komponenten auf, in die jeweils eine Austragpumpe 3 im Bereich des Flaschenhalses 4 ein­gesetzt ist. Die beiden Flaschenhälse 4 sind über eine in Draufsicht langrunde Anschlußkappe 5 derart formschlüssig miteinander verbunden, daß die beiden Speicher 2 mit geringem Abstand voneinander parallel zueinander sowie in gleicher Höhe vorgesehen sind. Im Bereich jedes etwa halbrunden Endes bildet die An­schlußkappe 5 an der Innenseite eine im wesentlichen achssymmetrische Verbindungskappe 6, welche im Be­reich des halbrunden Endes mit der Anschlußkappe 5 eine gemeinsame Wandung bildet und gleiche Höhe wie die Anschlußkappe 5 hat. Die Verbindungskappen 6 übergreifen die beiden Flaschenhälse 4 und sind über Schraub-Gewindeverbindungen 8 auf den Flaschenhälsen 4 festgezogen. Jede Verbindungskappe 6 bildet eine Hal­terung 7 für die zugehörige Austragpumpe 3 in Form einer einen Ringflansch des Pumpengehäuses aufnehmen­den Ringschulter, welche diesen Ringflansch 11 unter Zwischenlage einer Ringdichtung 9 gegen die äußere Stirnfläche des zugehörigen Flaschenhalses 4 spannt.As shown in FIGS. 1 to 4, a discharge device 1 according to the invention has two vial-shaped, essentially cylindrical stores 2 for storing media components, in each of which a discharge pump 3 is inserted in the area of the bottle neck 4. The two bottle necks 4 are positively connected to one another via a connection cap 5, which is long in plan view, in such a way that the two stores 2 are provided parallel to one another and at the same height at a short distance from one another. In the area of each approximately semicircular end, the connection cap 5 forms on the inside a substantially axially symmetrical connection cap 6, which forms a common wall with the connection cap 5 in the region of the semicircular end and has the same height as the connection cap 5. The connecting caps 6 overlap the two bottle necks 4 and are tightened via screw-threaded connections 8 on the bottle necks 4. Each connecting cap 6 forms a holder 7 for the associated discharge pump 3 in the form of an annular shoulder receiving an annular flange of the pump housing, which clamps this annular flange 11 with the interposition of an annular seal 9 against the outer end face of the associated bottle neck 4.

Beide Austragpumpen 3 sind mit einer gemeinsamen Hand­habe 10 in Form einer achsparallel zu den Austrag­pumpen 3 verschiebbaren Betätigungskappe verbunden, die im wesentlichen gleiche Grundform wie die An­schlußkappe 5 aufweist, jedoch gegenüber dieser in Draufsicht geringfügig kleiner ist. Die Handhabe 10 greift mit ihrem den Speichern 2 zugekehrten, lang­runden Wandungsrand 13 in die Innenseite eines sie mit geringem Spaltabstand umgebenden Ringsteges 12 ein, der über die äußere Stirnseite der die Stirn­ wandungen der Verbindungskappen 6 bildenden Stirn­wand der Anschlußkappe 5 vorsteht. In der den Wan­dungsrand 13 bildenden Umfangswand der Handhabe 10 ist benachbart zu deren zur Betätigung zu drückenden Stirnwand eine Auslaßöffnung 16 vorgesehen, die über Auslaßkanäle 14 der beiden Austragpumpen 3 und an diese anschließende Austrittskanäle 15 in der Handhabe 10 an die beiden Pumpenkammern beider Austragpumpen 3 angeschlossen ist. Die beiden Aus­tragpumpen 3 ihrerseits sind jeweils durch einen durch ein Steigrohr gebildeten Saugkanal 17 saug­seitig in Bodennähe an den zugehörigen Speicher 2 angeschlossen. Durch Niederdrücken der Handhabe 10 entgegen der Kraft von Rückstellfedern der beiden Austragpumpen 3 wird aus beiden Speichern 2 gleich­zeitig Medium in Richtung zur Auslaßöffnung 16 gefördert und vor Erreichen der Auslaßöffnung 16 durch ggf. verwirbeltes Zusammenführen mit der je­weils anderen Komponente gemischt, wonach das so hergestellte Mischmedium als ein einziger, ggf. versprühter Strahl aus der Austrittsöffnung 16 aus­tritt. Es ist aber auch denkbar, die beiden Kompo­nenten über gesonderte, unmittelbar benachbart zu­einander beispielsweise in konzentrischen Kränzen liegende Düsenöffnungen auszutragen und dadurch bereits im Bereich des Austrittes zusammenzubringen; die Düsenöffnungen können dann in einem gemeinsamen Düsenkörper vorgesehen sein. Im dargestellten Aus­führungsbeispiel sind die beiden achsgleich zuein­anderliegenden Austrittskanäle 15 bis zur Anschluß­stelle an einen Endkanal 18 gegeneinander gerichtet bzw. durch einen einzigen durchgehenden Kanal ge­bildet, an welchen der zur Auslaßöffnung 16 führen­de Endkanal 18 rechtwinklig angeschlossen ist; im Bereich dieses Anschlußes ist die Anordnung einer im Querschnitt ggf. erweiterten Wirbelkammer denkbar.Both discharge pumps 3 are connected to a common handle 10 in the form of an actuating cap which can be displaced axially parallel to the discharge pumps 3 and which has essentially the same basic shape as the connection cap 5, but is slightly smaller in plan view than this. The handle 10 engages with its long round wall edge 13 facing the accumulators 2 into the inside of an annular web 12 surrounding it with a small gap spacing, which extends over the outer end face of the forehead walls of the connecting caps 6 forming end wall of the connecting cap 5 protrudes. In the peripheral wall forming the wall edge 13 of the handle 10, an outlet opening 16 is provided adjacent to the end wall to be pressed for actuation and is connected to the two pump chambers of both discharge pumps 3 via outlet channels 14 of the two discharge pumps 3 and to these adjoining outlet channels 15 in the handle 10 is. The two discharge pumps 3 in turn are each connected to the associated storage unit 2 on the suction side near the floor by a suction channel 17 formed by a riser pipe. By depressing the handle 10 against the force of return springs of the two discharge pumps 3, medium is simultaneously conveyed from the two reservoirs 2 towards the outlet opening 16 and, before reaching the outlet opening 16, mixed with the other component by possibly swirling merging, after which the mixed medium thus produced emerges from the outlet opening 16 as a single, possibly sprayed jet. However, it is also conceivable to discharge the two components via separate nozzle openings located directly adjacent to one another, for example in concentric rings, and thereby bring them together in the area of the outlet; the nozzle openings can then be provided in a common nozzle body. In the illustrated embodiment, the two axially aligned outlet channels 15 are directed towards one another up to the connection point to an end channel 18 or are formed by a single continuous channel to which the end channel 18 leading to the outlet opening 16 is connected at right angles; In the area of this connection, the arrangement of a swirl chamber possibly enlarged in cross section is conceivable.

Die beiden Austrittskanäle 15 sind zweckmäßig gleich lang, so daß beide Komponenten etwa gleichen Strömungs­verhältnissen ausgesetzt sind. Die gemäß Fig. 2 am Ende eines frei vorstehenden Schnabels 19 vorge­sehene Auslaßöffnung 16 liegt an einer langen Sei­te der Handhabe 10 und zwar in der Mitte dieser langen Seite.The two outlet channels 15 are expediently of equal length, so that both components are exposed to approximately the same flow conditions. The outlet opening 16 provided at the end of a freely protruding beak 19 according to FIG. 2 lies on a long side of the handle 10 and in the middle of this long side.

Jede Austragpumpe 3 ist als Schubkolbenpumpe ausge­bildet, deren durch den Flaschenhals 4 in den zuge­hörigen Speicher 2 ragendes, zum Saugkanal 17 im Außendurchmesser mehrfach abgesetzt reduziertes Zylindergehäuse 20 über seine gesamte Länge mit Ab­stand vom Innenumfang des Flaschenhalses 4 liegt. Die Austragpumpe 3 weist eine im Zylindergehäuse 20 verschiebbare Kolbeneinheit 21 mit einer elastischen Kolbenmanschette 22 auf, die an ihrem äußeren Ende einteilig mit einer elastisch federnden Stauchhülse 23 ausgebildet ist. Die Kolbenmanschette 22 und die Stauchhülse 23 sind am Außenumfang eines Kolben­stößels 24 angeordnet, welcher aus dem Pumpengehäuse und über den Ringsteg 12 in die Handhabe 10 vorsteht und von dem Auslaßkanal 14 durchsetzt ist. Die Kolben­manschette 22 bildet im Übergangsbereich zur Stauch­hülse 23 den äußeren, ringförmigen Ventilschließ­teil eines im einzelnen nicht näher dargestellten Auslaßventiles 25, dessen Ventilsitz am Kolben­stößel 24 vorgesehen ist. Die Kolbenmanschette 22 kann einschließlich des Ventilschließteiles unter rückfedernder Stauchung der Stauchhülse 23 gegenüber dem Kolbenstößel 24 entgegen der Richtung des Pump­hubes bewegt werden, wodurch das Auslaßventil 25 öffnet. Diese Bewegung kann entweder gegen Ende des Pumphubes durch Anschlag der Kolbenmanschette 22 an einer Innenschulter des Zylindergehäuses 20 zwangs­ läufig oder druckabhängig durch einen entsprechen­den Überdruck in der Pumpenkammer erfolgen. Das äußere Ende des Zylindergehäuses 20 ist von einer Zylinderdeckelkappe 27 verschlossen, die den Ring­flansch 11 bildet und von dem Kolbenstößel 24 durch­setzt ist. Zwischen der Pumpenkammer und dem Saug­kanal 17 weist jede Austragpumpe 3 ein Einlaßven­til 26 in Form eines Kugelventiles auf, welches bei Überdruck in der Pumpenkammer, also während des Pumphubes, schließt.Each discharge pump 3 is designed as a thrust piston pump, the cylinder housing 20 of which extends through the bottle neck 4 into the associated accumulator 2 and is reduced in its outer diameter several times to the suction channel 17 over its entire length at a distance from the inner circumference of the bottle neck 4. The discharge pump 3 has a piston unit 21 which is displaceable in the cylinder housing 20 and has an elastic piston sleeve 22 which is formed in one piece with an elastically resilient compression sleeve 23 at its outer end. The piston sleeve 22 and the compression sleeve 23 are arranged on the outer circumference of a piston tappet 24 which protrudes from the pump housing and over the ring web 12 into the handle 10 and is penetrated by the outlet channel 14. The piston sleeve 22 forms in the transition area to the compression sleeve 23 the outer, annular valve closing part of an exhaust valve 25, not shown in detail, the valve seat of which is provided on the piston tappet 24. The piston sleeve 22, including the valve closing part, can be moved against the direction of the pump stroke with resilient compression of the compression sleeve 23 relative to the piston tappet 24, as a result of which the outlet valve 25 opens. This movement can either be forced towards the end of the pump stroke by abutment of the piston sleeve 22 on an inner shoulder of the cylinder housing 20 be carried out frequently or depending on the pressure by a corresponding overpressure in the pump chamber. The outer end of the cylinder housing 20 is closed by a cylinder cover cap 27, which forms the annular flange 11 and is penetrated by the piston tappet 24. Between the pump chamber and the suction channel 17, each discharge pump 3 has an inlet valve 26 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.

Die Handhabe 10 weist an der Innenseite ihrer Stirn­wand, welche auch die Austrittskanäle 15 enthält, eine der Anzahl der Speicher 2 entsprechende Anzahl von vorstehenden Steckmuffen 28 auf, die axial ge­sichert durch Aufstecken mit den äußeren Enden der Kolbenstößel 24 verbunden sind, derart, daß alle Zylinderdeckelkappen 27 der Austragpumpen 3 von der Handhabe 10 überdeckt sind.The handle 10 has on the inside of its end wall, which also contains the outlet channels 15, a number of protruding push-in sleeves 28 corresponding to the number of stores 2, which are axially secured by being connected to the outer ends of the piston tappets 24 such that all Cylinder cover caps 27 of the discharge pumps 3 are covered by the handle 10.

Zur Stabilisierung der Lage der Speicher 2 gegenein­ander in deren der Handhabe 10 gegenüberliegenden Bodenbereich ist eine Halterungsbrücke 29 in Form einer langrunden Flachschale vorgesehen, welche mit ihren teilkreisförmigen Wandungsabschnitten die Speicher 2 durch Aufstecken eng umschließt und mit ihrer Bodenplatte die Standfläche der Austragvor­richtung bildet. Die Halterungsbrücke 29 bildet einen gesonderten Bauteil, so daß die Speicher 2 zuerst an der Anschlußkappe 5 befestigt werden können, wonach die Halterungsbrücke 29 angebracht wird.To stabilize the position of the accumulators 2 relative to one another in their bottom area opposite the handle 10, a mounting bridge 29 is provided in the form of a long round flat shell which, with its part-circular wall sections, tightly encloses the accumulators 2 by plugging on and forms the base of the discharge device with its base plate. The bracket bridge 29 forms a separate component, so that the memory 2 can first be attached to the connection cap 5, after which the bracket bridge 29 is attached.

Wie Fig. 4 zeigt, kann im Bereich der Auslaßöffnung 16 bzw. benachbart zu dieser ein Düsenkörper 30 im Strömungsweg der Medien vorgesehen sein, der am Um­ fang mit Drallnuten 31 versehen ist. Statt dessen oder zusätzlich hierzu können auch an mindestens einer Stirnseite des Düsenkörpers 30 Spiralnuten 32 vorgesehen sein. Die zu mischenden Medien-Kompo­nenten werden entweder gesondert oder bereits zu­sammengeführt dem Düsenkörper 30 zugeführt, wo sie stark verwirbelt und dadurch intensiv vermischt werden, wonach sie, ggf. als Sprühstrahl, durch die Auslaßöffnung 16 austreten.As shown in FIG. 4, a nozzle body 30 can be provided in the flow path of the media in the region of the outlet opening 16 or adjacent to it catch is provided with swirl grooves 31. Instead of or in addition to this, 30 spiral grooves 32 can also be provided on at least one end face of the nozzle body. The media components to be mixed are either supplied separately or already brought together to the nozzle body 30, where they are swirled strongly and thereby intensively mixed, after which they emerge through the outlet opening 16, optionally as a spray jet.

Bei der Ausführungsform gem. Fig. 5 ist für jede Komponente eine gesonderte Auslaßöffnung 16a vor­gesehen, wobei die beiden Auslaßöffnungen 16a im dargestellten Ausführungsbeispiel nahe benachbart zueinander an den Enden von schräg gegeneinander ge­richtet vorstehenden Schnäbeln 19a vorgesehen sind. Die Austrittskanäle 15a stehen innerhalb der Aus­tragvorrichtung 1a nicht in Verbindung miteinander, sondern die Medien-Komponenten treffen erst un­mittelbar nach Verlassen der Auslaßöffnungen 16a außerhalb der Austragvorrichtung 1a und in unmittel­barer Nähe der Auslaßöffnungen 16a aufeinander, so daß sie dann hier zusammengeführt und gemischt werden.In the embodiment according to 5, a separate outlet opening 16a is provided for each component, the two outlet openings 16a being provided in the exemplary embodiment shown close to one another at the ends of beaks 19a projecting at an angle to one another. The outlet channels 15a are not connected to one another within the discharge device 1a, but the media components meet only immediately after leaving the outlet openings 16a outside the discharge device 1a and in the immediate vicinity of the outlet openings 16a, so that they are then brought together and mixed here.

Besonders vorteilhaft ist es, wenn mindestens eine oder mindestens zwei Austragpumpen hinsichtlich ihrer Austrag­menge durch Einstellung veränderbar sind, beispielsweise gemäß Patentanmeldung P 32 25 910.7, auf die wegen wei­terer Einzelheiten Bezug genommen wird. Dadurch läßt sich das Mischungsverhältnis der Komponenten jederzeit an die Erfordernisse anpassen.It is particularly advantageous if at least one or at least two discharge pumps can be changed with regard to their discharge quantity by adjustment, for example according to patent application P 32 25 910.7, to which reference is made for further details. This allows the mixing ratio of the components to be adapted to requirements at any time.
