Description

Die Erfindung betrifft einem Vorratsbehälter und ein System zur Abgabe von mindestens zwei Wirkstofffluiden gemäß dem Oberbegriff der Ansprüche 1, 5 und 7.The invention relates to a storage container and a system for dispensing at least two active substance fluids according to the preamble of claims 1, 5 and 7.

Stand der TechnikState of the art

Der Begriff Wirkstofffluid meint fließfähige, also flüssige bis zähflüssige, ggf. gelartige oder auch pastenartige oder granulatförmige oder anderweit schüttfähige Wirkstoffzubereitungen mit reinigender, desinfizierender, desodorierender, bleichender u.ä. Wirkung (insbesondere beschrieben DE 199 30 362 A1 , sowie in der EP 0 775 741 A1 und der EP 0 960 984 A2 ).The term active ingredient fluid means flowable, that is liquid to viscous, possibly gelatinous or pasty or granular or otherwise pourable active substance preparations with cleansing, disinfecting, deodorizing, bleaching and the like. Effect (especially described DE 199 30 362 A1 , as well as in the EP 0 775 741 A1 and the EP 0 960 984 A2 ).

Abgabevorrichtungen der in Rede stehenden Art sind unter dem Stichwort "WC-Körbchen" in verschiedenen Ausführungen bekannt. Bekannt sind zunächst Abgabevorrichtungen für ein einzelnes Wirkstofffluid. Das Wirkstofffluid befindet sich dort in einem in einem Halter fest angeordneten oder auswechselbar eingesetzten Vorratsbehälter mit einer bei am Halter angebrachtem Vorratsbehälter bodenseitig angeordnetem Auslaßöffnung.Dispensers of the type in question are known under the keyword "toilet bowl" in different versions. First, dispensing devices for a single active substance fluid are known. The drug fluid is there in a fixed in a holder or interchangeably inserted reservoir with a mounted on the holder reservoir bottom outlet opening arranged.

Bei einer ersten bekannten Abgabevorrichtung für ein einzelnes Wirkstofffluid wird das Wirkstofffluid über ein damit tränkbares, mit der Spülflüssigkeit beaufschlagbares Betätigungselement (z.B. aus einem offenporigen Schaumstoff) zugegeben ( EP 785 315 A1 ). Hier wird die Auslaßöffnung des Vorratsbehälters nach Herausstoßen eines Verschlußteils des Vorratsbehälters von einem am Halter ortsfest angeordneten Dichtungselement großteilig verschlossen, so daß nur noch ein Strömungsweg mit geringem Querschnitt zum Heraussickern des Wirkstofffluids zur Verfügung steht. Die Vorrichtung funktioniert unter Nutzung der Kapillarwirkung des offenporigen Schaumstoffs. Eine ähnliche Konstruktion ist auch mit einer der Verteilung dienenden Rippenplatte bekannt.In a first known dispensing device for a single active substance fluid, the active substance fluid is added via an actuating element (eg made of an open-cell foam) which can be impregnated therewith and acted upon by the irrigation fluid ( EP 785 315 A1 ). Here, the outlet opening of the reservoir after expulsion of a closure member of the reservoir of a holder fixedly arranged on the sealing member is largely closed, so that only a flow path with a small cross-section for leakage of the active ingredient fluid is available. The device works by utilizing the capillary action of the open cell foam. A similar construction is also known with a distribution ribbed plate.

Bei der Verwendung zuvor erläuterter Abgabevorrichtungen der in Rede stehenden Art müssen alle Komponenten, die in die Spülflüssigkeit des Toilettenbeckens gelangen, im Wirkstofffluid gemeinsam enthalten sein. Manche Wirkstoffkomponenten sind aber nicht gemeinsam lagerstabil zu realisieren. Deshalb hat man bereits eine Mehrkammer-Abgabevorrichtung vorgeschlagen ( EP 0 960 984 A2 ). Diese bekannte Abgabevorrichtung, dient zur Abgabe von mindestens zwei unterschiedlichen oder gleichen festen, gelartigen, pastösen oder flüssigen Medien in flüssiger oder wässriger Form in ein Toilettenbecken. An einem am Rand des Toilettenbeckens aufhängbaren Halter befindet sich ein Behälter, der zum Bevorraten der Medien mindestens zwei nebeneinander angeordnete eigenständige Kammern aufweist. Jede Kammer hat eine Abgabeeinrichtung mit einem Abgaberöhrchen, das mit seinem einen freien Ende über den Boden des Behälters in die Umgebung austritt und an seinem anderen freien Ende Fluid führend von einer Abdeckung umgeben ist. Die beiden Kammern des Behälters sind über schlitzartige Durchlässe eines Deckelteils von überströmendem Spülwasser befüllbar, das dann nach Art eines Siphons oder Überlaufs über die Abgaberöhrchen unter Mitnahme des jeweiligen Wirkstoffs in das Toilettenbecken austritt. Die Trennung der Kammern in dem Behälter hat den Vorteil, daß unterschiedliche Medien eingesetzt werden können, die ansonsten bei einer gemeinsamen Bevorratung in nur einer Kammer sich in ihrer gewünschten Wirkung schädlich beeinflussen würden. Auch die Konsistenz der Medien kann in den unterschiedlichen Kammern unterschiedlich sein.When using previously explained dispensing devices of the type in question, all components that enter the rinsing fluid of the toilet bowl must be contained in the active substance fluid together. However, some active ingredient components can not be realized together in a storage-stable manner. Therefore, a multi-chamber dispenser has already been proposed ( EP 0 960 984 A2 ). This known dispensing device is used to dispense at least two different or the same solid, gel-like, pasty or liquid media in liquid or aqueous form in a toilet bowl. On a suspendable on the edge of the toilet bowl holder is a container which has for storing the media at least two juxtaposed independent chambers. Each chamber has a dispenser with a dispensing tube, which exits with its one free end over the bottom of the container into the environment and at its other free end fluid leading surrounded by a cover. The two chambers of the container can be filled via slit-like passages of a cover part of overflowing rinse water, which then exits in the manner of a siphon or overflow via the delivery tube with entrainment of the respective active ingredient in the toilet bowl. The separation of the chambers in the container has the advantage that different media can be used, which would otherwise be detrimental to their desired effect in a common storage in only one chamber. The consistency of the media may vary in the different chambers.

Bei der zuvor erläuterten Abgabevorrichtung, wird das Funktionsprinzip bekannter "WC-Körbchen" genutzt, nach dem von oben her überströmendes Spülwasser in die das Wirkstofffluid enthaltenden Kammern einströmt, Teile der Wirkstoffsubstanz löst und unter Mitführung dieser aus den Kammern wieder abfließt. Dabei besteht das Problem darin, daß mit dem hier verwirklichten Siphoneffekt in den Kammern ein erheblicher Flüssigkeitsspiegel zurückbleibt. Die Einwirkung der Spülflüssigkeit auf das Wirkstofffluid in der jeweiligen Kammer geht also weiter, auch wenn der Spülvorgang lange abgeschlossen worden ist. Der Verbrauch von Wirkstofffluid ist praktisch nicht optimal zu steuern.In the previously described dispensing device, the principle of operation known "toilet bowl" is used, after flowing from above overflow rinse water flows into the fluid containing chambers, parts of the drug substance dissolves and flows with this entrainment from the chambers again. The problem is that with the siphon effect realized in the chambers, a considerable amount of liquid remains behind. The action of the rinsing liquid on the active substance fluid in the respective chamber therefore continues, even if the rinsing process has been completed for a long time. The consumption of active substance fluid is practically not optimal to control.

Es ist üblich, dass derartige Mehrkammersysteme jeweils eine Auslassöffnung für ein Wirkstofffluid aus einer der Kammern bereitstellen. Häufig werden daher entweder zwei separat ausgeformte Kammern mit jeweils einer Auslassöffnung miteinander gekuppelt im WC-Körbchen angeordnet. Alternativ kann ein einstückiger Vorratsbehälter mit zwei Kammern und zwei Auslassöffnungen vorgesehen sein.It is common that such multi-chamber systems each provide an outlet port for a drug fluid from one of the chambers. Often, therefore, either two separately formed chambers, each with an outlet opening are coupled together arranged in the toilet bowl. Alternatively, a one-piece reservoir with two chambers and two outlet openings may be provided.

Durch die Ausbildung von zwei separierten Auslassöffnungen ist es häufig notwendig, auch zwei Abgabevorrichtungen vorzusehen, die die Abgabe von Wirkstofffluid aus den Vorratsbehältern in die Spülflüssigkeit des Toilettenbeckens steuern. Hier sind beispielsweise Ventilanordnungen bekannt, bei denen ein mit Spülwasser beaufschlagter Hebel mit einem Ventil verbunden ist, dass beim Abspülen die Freisetzung einer Teilmenge an Wirkstofffluid aus einem der Vorratsbehälter bewirkt. Andere Abgabevorrichtungen sind beispielsweise durch Kapillarwirkungen realisiert, die sich zwischen den Wirkstofffluiden und entsprechend dimensionierten Abgabekanälen ausbilden und somit ein freies Fließen eines Wirkstofffluids aus dem Vorratsbehälter verhindern.With the formation of two separate outlet ports, it is often necessary to provide two dispensers which control the delivery of active fluid from the reservoirs into the flushing fluid of the toilet bowl. Here, for example, valve arrangements are known in which a flushing water acted upon lever is connected to a valve that causes the release of a subset of active fluid from one of the reservoir during rinsing. Other dispensing devices are realized, for example, by capillary action that forms between the drug fluids and appropriately sized dispensing channels, thus preventing free flow of active fluid from the reservoir.

Die Ausbildung von zwei separierten Abgabevorrichtungen für die jeweiligen Auslassöffnungen ist aufwendig und kostenintensiv.The formation of two separate dispensing devices for the respective outlet openings is complicated and costly.

Ferner ist häufig nicht gewährleistet, dass es zu einer gleichmäßigen Abgabe von Wirkstoffluiden aus den jeweiligen Behältern kommt, da die Abgabevorrichtungen beispielsweise ungleichmäßig öffnen und schließen. So kommt es häufig vor, dass bereits eine Kammer vollständig von Wirkstofffluid entleert ist, während in der anderen noch Wirkstofffluid ansteht, wodurch die Fehlfunktion eines derartigen WC-Körbchens für den Verbraucher sofort ersichtlich ist.Furthermore, it is often not ensured that there is a uniform delivery of active fluids from the respective containers, since the dispensing devices open and close, for example unevenly. Thus, it often happens that one chamber is already completely emptied of active substance fluid, while in the other still drug fluid is present, whereby the malfunction of such a toilet bowl for the consumer is immediately apparent.

Andere Abgabesysteme sind in WO 2006106987 , US 4581777 oder GB2194258 offenbart.Other delivery systems are in WO 2006106987 . US 4581777 or GB2194258 disclosed.

Aufgabe der ErfindungObject of the invention

Aufgabe der Erfindung ist es daher die geschilderten, aus dem Stand der Technik bekannten Nachteile zu überwinden und ein Abgabesystem für wenigstens zwei Wirkstofffluide zu schaffen, das auf einfache und kostengünstige Weise herzustellen ist und das eine gleichzeitige und gleichmäßige Abgabe der Wirkstofffluide in die Spülflüssigkeit eines Toilettenbeckens gewährleistet.The object of the invention is therefore to overcome the described, known from the prior art disadvantages and to provide a delivery system for at least two active fluids, which is to produce in a simple and cost-effective manner and that a simultaneous and uniform delivery of the active fluids in the rinsing fluid of a toilet bowl guaranteed.

Die Aufgabe wird durch ein Abgabesystem gemäß Anspruch 1 und 5 sowie durch einen Vorratsbehälter gemäß Anspruch 7 zur Verwendung in einem Abgabesystem gelöst.The object is achieved by a dispensing system according to claims 1 and 5 and by a storage container according to claim 7 for use in a dispensing system.

Durch die Ausbildung einer einzigen Abgabeöffnung für eine Mehrzahl von Wirkstofffluiden ist sichergestellt, dass die Wirkstofffluide gleichmäßig in die Spülflüssigkeit abgegeben werden und eine ungleichmäßige Abgabe, wie sie beispielsweise bei einer ungleichmäßigen Beaufschlagung der Abspülplatte bei WC-Spülern mit wenigstens zwei Abgabeöffnungen vorkommen kann, verhindert wird.The formation of a single discharge opening for a plurality of active substance fluids ensures that the active substance fluids are dispensed uniformly into the rinsing fluid and prevents uneven delivery, as may occur, for example, in the case of uneven loading of the rinsing plate in toilet rinsers with at least two discharge openings ,

Ferner ist der fertigungstechnische Aufwand verglichen mit dem aus dem Stand der Technik bekannten WC-Spülern deutlich geringer, da nicht für jedes einzelne Fluid eine Ventil- oder sonstige Fließkontrollvorrichtung notwendig ist, sondern lediglich eine Ventil- oder sonstige Fließkontrollvorrichtung für alle Wirkstofffluide benötigt wird.Furthermore, the manufacturing effort compared to the known from the prior art toilet bowls significantly lower because not every single fluid valve or other flow control device is necessary, but only a valve or other flow control device is needed for all drug fluids.

Vorratsbehälterreservoir

Ein Vorratsbehälter im Sinne dieser Anmeldung ist ein Behälter, der zur Aufnahme eines fließ- oder streufähigen Produktes geeignet ist. Der Vorratsbehälter verfügt über eine bodenseitige Abgabeöffnung, aus der die Wirkstofffluide austreten.A storage container in the sense of this application is a container which is suitable for receiving a flowable or spreadable product. The storage container has a bottom-side discharge opening, from which the active substance fluids emerge.

Es ist besonders bevorzugt, die Vorratsbehälter einstückig auszuformen. Die Vorratsbehälter können durch eine Trennwand zumindest abschnittsweise voneinander separiert sein.It is particularly preferred to form the storage container in one piece. The storage containers can be separated from each other by a partition at least in sections.

Es ist jedoch auch denkbar dass die Vorratsbehälter mehrstückig ausgeformt sind. Die Vorratsbehälter verfügen über eine gemeinsame, bodenseitige Abgabeöffnung.However, it is also conceivable that the reservoir are formed in several pieces. The reservoirs have a common, bottom-side discharge opening.

Im Abgabesystem der vorliegenden Erfindung sind zwei Vorratsbehälter vorgesehen, die, bevorzug voneinander separiert sind, und jeweils ein Wirkstofffluid enthalten. Es kann aber auch mehrere Vorratsbehälter für mehrere Wirkstofffluide geben. Die Vorratsbehälter sind voneinander separiert, um eine vorzeitige Mischung der Wirkstofffluide zu unterbinden. Sie können körperlich separat oder als separate Abteile in einem zusammenhängenden Körper ausgebildet sein.In the delivery system of the present invention, two reservoirs are provided, which are preferably separated from each other and each contain a drug fluid. But there may also be several reservoirs for multiple drug fluids. The reservoirs are separated from each other to prevent premature mixing of the drug fluids. They may be physically separate or formed as separate compartments in a contiguous body.

In einer weiteren Ausführungsform ist vorgesehen, dass an dem WC-Spüler ein Vorratsbehälter mit einer bodenseitigen Öffnung ausgeformt ist, wobei die Wirkstofffluide im Vorratsbehälter im Wesentlichen nicht miteinander mischbare Phasen mit vertikal verlaufenden Phasengrenzen ausbilden und die Phasengrenze bevorzugt mittig über der Abgabeöffnung steht.In a further embodiment, provision is made for a storage container having a bottom-side opening to be formed on the toilet freshener, wherein the active-substance fluids form in the reservoir substantially immiscible phases with vertically extending phase boundaries and the phase boundary is preferably centrally above the discharge opening.

Die bodenseitige Abgabeöffnung kann mittig oder versetzt zur Mitte des WC-Spülers angeordnet sein.The bottom-side discharge opening may be arranged centrally or offset to the center of the toilet rinser.

Die Böden können insbesondere zur Öffnung hin abfallend ausgebildet sein, um eine vollständige Restentleerbarkeit der Wirkstofffluide aus den Vorratsbehältern zu gewährleisten.The floors may be sloping, in particular, towards the opening in order to ensure complete emptying of the active substance fluids from the storage containers.

Es ist insbesondere bevorzugt, den Vorratsbehälter transparent auszubilden, um eine Füllstandskontrolle bezüglich der bevorrateten Wirkstofffluide zu erlauben.It is particularly preferred to form the reservoir transparent to allow a level control with respect to the stored drug fluids.

Es ist ferner denkbar, dass der Vorratsbehälter gemeinsam mit einer Abgabevorrichtung konfektioniert angeboten wird. Es ist jedoch auch möglich, dass der Vorratsbehälter als Nachfüll- oder Austauscheinheit konfiguriert ist.It is also conceivable that the storage container is offered ready made together with a dispenser. However, it is also possible that the reservoir is configured as a refill or exchange unit.

Abgabevorrichtungdispenser

Eine Abgabevorrichtung im Sinne dieser Anmeldung ist eine der Abgabeöffnung der Vorratsbehälter in Fließrichtung der Wirkstofffluide nachgeschaltete Anordnung, die die Abgabe der Wirkstofffluide in die Spülflüssigkeit steuert.For the purposes of this application, a dispensing device is an arrangement arranged downstream of the dispensing opening of the storage container in the direction of flow of the active substance fluids, which controls the dispensing of the active substance fluids into the rinsing liquid.

Steuern bedeutet in diesem Zusammenhang, dass ein freies Fließen der Wirkstofffluide durch die Abgabevorrichtung verhindert ist und eine Freisetzung von Produkt durch die Abgabevorrichtung insbesondere unmittelbar vor, während oder nach einem Spülvorgang der Toilette erfolgt.Control in this context means that a free flow of the active substance fluids is prevented by the dispensing device and a release of product by the dispensing device takes place in particular immediately before, during or after a rinsing process of the toilet.

Die Abgabe kann beispielsweise durch den Spülwasserschwall des Toilettenbeckens bewirkt sein, indem der Spülwasserschwall beispielsweise eine Ventilanordnung öffnet. Die Abgabevorrichtung kann auch durch eine Anordnung realisiert sein, die ein freies Fließen der Wirkstofffluide aus den Vorratsbehältern zum Beispiel durch Kapillarwirkungen verhindert. Es wird hierzu auf die Abgabevorrichtungen verwiesen, die aus der EP1334239 B, siehe auch WO 0240791 , bekannt sind. Das Dokument WO 0240791 wird als nächstliegender Stand der Technik angesehen. Das Dokument offenbart die Merkmale, die im Oberbegriff der Ansprüche 1, 5 und 7 beschrieben sind.The dispensing may be effected, for example, by the flushing water surge of the toilet bowl, for example, by the Spülwasserschwall opens a valve assembly. The dispenser may also be realized by an arrangement which prevents free flow of the active fluids from the reservoirs, for example by capillary action. Reference is made to the dispensers, the from the EP1334239 B, see also WO 0240791 , are known. The document WO 0240791 is considered to be the closest prior art. The document discloses the features described in the preamble of claims 1, 5 and 7.

Wirkstofffluidactive fluid

Die fließfähigen Wirkstofffluide sind insbesondere durch ihre jeweilige Viskositäten in derart konfiguriert, dass sie im Wesentlichen nicht miteinander mischbare Phasen mit vertikal verlaufenden Phasengrenzen ausbilden können.The flowable drug fluids are particularly configured by their respective viscosities in such that they can form substantially immiscible phases with vertically extending phase boundaries.

Es ist besonders bevorzugt, dass genau zwei voneinander verschiedene Wirkstofffluide eine vertikal durch den Vorratsbehälter verlaufende Phasengrenze ausbilden, wobei die Phasengrenze in etwa mittig über der Abgabeöffnung verläuft.It is particularly preferred that exactly two different drug fluids form a vertically extending through the reservoir phase boundary, wherein the phase boundary extends approximately centrally above the discharge opening.

Fig. 1 WC-Spüler in perspektivischer Ansicht Fig. 1 Toilet freshener in perspective view

Fig. 1 zeigt einen WC-Spüler 1 mit einem ersten Vorratsbehälter 2 und einem zweiten Vorratsbehälter 3. Die Vorratsbehälter sind mit jeweils voneinander verschiedenen Wirkstofffluiden 4,5 gefüllt. Fig. 1 shows a toilet freshener 1 with a first reservoir 2 and a second reservoir 3. The reservoirs are filled with each different drug fluids 4,5.

Die Vorratsbehälter 2,3 sind durch eine Trennwand 6 zumindest abschnittsweise voneinander separiert. Wie in Fig. 1 gezeigt, schließt die Trennwand 6 mit dem Boden 12, 11 ab.The storage containers 2, 3 are separated from each other at least in sections by a partition wall 6. As in Fig. 1 shown, the partition 6 closes with the bottom 12, 11 from.

Die Trennwand 6 kann als eine geschlossene Fläche ausgeformt sein. Die Trennwand 6 kann auch Öffnungen aufweisen, wobei die Öffnungen in derart ausgeführt sind, dass eine Vermischung der Wirkstofffluide 4,5 verhindert ist. Die Trennwand kann demnach in einer weiteren Ausführungsform als engmaschiges Gitter ausgebildet sein. Die Trennwand 6 kann auch als Folie oder Film ausgebildet sein.The partition wall 6 may be formed as a closed surface. The partition wall 6 may also have openings, wherein the openings are designed in such a way that mixing of the active substance fluids 4, 5 is prevented. The partition can therefore be formed in a further embodiment as a close-meshed grid. The partition wall 6 may also be formed as a film or film.

Die Trennwand 6 ist mit einem oder beiden der Vorratsbehälter 2,3 fest verbunden. In einer weiteren Ausführungsform der Erfindung, die nicht in den Abbildungen gezeigt ist, ist es auch denkbar, dass die Trennwand 6 keine Verbindung mit dem Vorratsbehälter aufweist, also zwischen den Wirkstofffluiden 4,5 schwimmend gelagert ist.The partition 6 is firmly connected to one or both of the reservoir 2.3. In a further embodiment of the invention, which is not shown in the figures, it is also conceivable that the dividing wall 6 has no connection to the storage container, that is, it is floatingly mounted between the active substance fluids 4, 5.

Wie in Fig. 1 nicht gezeigt, ist es jedoch auch möglich, die Trennwand 6 aus den Vorratsbehältern 2,3 zu entfernen und die Wirkstofffluide 4,5 in derart zu konfigurieren, dass die voneinander verschiedenen Wirkstofffluide eine vertikal durch den Vorratsbehälter verlaufende Phasengrenze ausbilden, wobei die Phasengrenze in etwa mittig über der Abgabeöffnung verläuft.As in Fig. 1 not shown, however, it is also possible to remove the partition 6 from the reservoirs 2, 3 and to configure the active fluids 4, 5 in such a way that the mutually different active fluids form a phase boundary running vertically through the reservoir, the phase boundary being approximately runs centrally above the discharge opening.

Bei der dargestellten Abgabevorrichtung weist der Vorratsbehälter 2 einen Behälterstutzen 8 auf, bei dem sich im verschlossenen Zustand der Vorratsbehälters 2,3 ein Verschluss befindet.In the case of the dispensing device shown, the storage container 2 has a container neck 8, in which a closure is located in the closed state of the storage container 2, 3.

Für die Abgabe der Wirkstofffluid 4,5 aus den Vorratsbehältern 2,3 sind Gravitation, Unterdruck oberhalb des Flüssigkeitsspiegels der Wirkstofffluid 4,5 in denFor the delivery of the active substance fluid 4,5 from the storage containers 2, 3, gravitation, negative pressure above the liquid level of the active substance fluid 4, 5 are in the

Vorratsbehältern 2,3, Verdünnung der Wirkstofffluide 4,5 an der Abgabestelle, ebenso von Bedeutung wie die räumliche Lage der Abgabevorrichtung im Toilettenbecken, die Intensität der Strömung der Spülflüssigkeit.Reservoirs 2,3, dilution of the active substance fluids 4,5 at the delivery point, as important as the spatial position of the dispenser in the toilet bowl, the intensity of the flow of the rinsing liquid.

Die Vorratsbehälter 2,3 sind gegen den Eintritt von Spülflüssigkeit aus der WC-Spülung geschützt und verfügen jeweils über einen Boden 11,12, wobei die Böden 11,12 der Vorratsbehälter 2,3 eine gemeinsame bodenseitige Öffnung 7 aufweisen, aus der die Wirkstofffluide 4,5 austreten können. Das Mischungsverhältnis der Wirkstofffluide 4,5 kann durch die Größe und Lage der Öffnung 7 sowie durch Konfiguration der Fließeigenschaften der Wirkstofffluide beeinflusst werden.The storage containers 2, 3 are protected against the entry of rinsing liquid from the toilet rinse and each have a bottom 11, 12, the bottoms 11, 12 of the storage containers 2, 3 having a common bottom-side opening 7, from which the active-substance fluids 4 , 5 can escape. The mixing ratio of the active fluids 4, 5 can be influenced by the size and position of the opening 7 as well as by the configuration of the flow properties of the active substance fluids.

Von der Öffnung 7 erstreckt sich in bodenseitiger Richtung ein Behälterstutzen 8 an dem sich in Fließrichtung nachfolgend eine Abgabevorrichtung 13 befindet, die die Abgabe der Wirkstofffluide 4,5 in die Umgebung und/oder die Spülflüssigkeit steuert.Extending from the opening 7 in the bottom-side direction is a container nozzle 8, on which there is a downstream delivery device 13 in the direction of flow, which controls the delivery of the active substance fluids 4, 5 into the environment and / or the rinsing liquid.

Die Abgabevorrichtung kann beispielsweise ventilgesteuert sein oder durch eine Anordnung realisiert sein, die ein freies Fließen der Wirkstofffluide verhindert, zum Beispiel durch Kapillarwirkung.For example, the dispenser may be valve-controlled or may be implemented by an arrangement that prevents free flow of the active fluids, for example by capillary action.

Von der Abgabevorrichtung 13 gelangen die Wirkstofffluide 4,5 auf eine Abspülplatte 9, wo sich durch die Beaufschlagung mit Spülflüssigkeit aufgelöst und mitgeschwemmt werden.From the dispensing device 13, the active-substance fluids 4, 5 reach a rinsing plate 9, where they are dissolved and co-washed by the application of rinsing liquid.
