Description

Vorrichtung zur Abgabe eines flüssigen Wirkstoffs in ein Spülwasser Device for dispensing a liquid active substance into a rinse water
Die Erfindung betrifft eine Vorrichtung zur Abgabe eines flüssigen Wirkstoffs in ein Spülwasser, insbesondere in ein Toilettenbecken gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for dispensing a liquid active substance into a flushing water, in particular into a toilet bowl, according to the preamble of patent claim 1.
Aus der DE 199 12 217 AI ist eine Vorrichtung zur Abgabe eines flüssigen Wirkstoffs bekannt. Diese Vorrichtung weist einen Behälter zur Aufnahme des flüssigen Wirkstoffs auf, der eine unterseitige Öffnung besitzt. Dieser Öffnung ist eine Verteilerplatte zugeordnet, die den aus dem Behälter austretenden flüssigen Wirkstoff über deren Oberfläche verteilt. Die Verteilerplatte ist von einem Teilrahmen umgeben, über den der Wirkstoff zusammen mit dem Spülwasser abgeleitet wird. Diese bekannte Vorrichtung hat sich in der Praxis gut bewährt. Allerdings hat sich herausgestellt, daß der Wirkstoff nach dem Spülvorgang in das Toilettenbecken nachtropft, was insbesondere bei färbenden Wirkstoffen zu unansehnlichen Tropfspuren im Toilettenbecken führt.DE 199 12 217 AI discloses a device for dispensing a liquid active substance. This device has a container for holding the liquid active substance, which has an opening on the underside. A distribution plate is assigned to this opening, which distributes the liquid active substance emerging from the container over its surface. The distributor plate is surrounded by a subframe, via which the active ingredient is drained off together with the rinse water. This known device has proven itself in practice. However, it has been found that the active ingredient drips into the toilet bowl after the flushing process, which in particular with coloring agents leads to unsightly drip marks in the toilet bowl.
Der Erfindung liegt die Aufgabe zugrunde, die eingangs genannte Vorrichtung dahingehend zu verbessern, daß ein Nachtropfen des flüssigen Wirkstoffs zuverlässig verhindert wird.The invention has for its object to improve the above-mentioned device so that dripping of the liquid active ingredient is reliably prevented.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with the features of claim 1.
Die Vorrichtung gemäß Anspruch 1 weist einen Behälter auf, der einen flüssigen Wirkstoff aufnimmt. Ein flüssiger Wirkstoff hat gegenüber einem festen Wirkstoff den Vorteil, daß dieser in gleichbleibender Qualität und insbesondere Konzentration vorliegt, so daß dessen Wirkung für die gesamte Einsatzdauer konstant bleibt. Als Wirkstoffe kommen insbesondere Duftstoffe, Reinigungsmittel vorzugsweise in der Form von Tensiden und Färbemittel, insbesondere Blaufärbemittel in Frage. Diese Wirkstoffe müssen in bestimmter Dosierung dem Spülwasser zugesetzt werden, damit sie ihre optimale Wirkung entfalten können. Zu diesem Zweck steht die Öffnung des Behälters mit einer Verteilerplatte in Wirkverbindung, die den Wirkstoff über deren Oberfläche möglichst gleichmäßig verteilt. Insbesondere beim Einsatz von Duftstoffen als Wirkstoffkompo- nente sorgt diese flächige Verteilung des Wirkstoffs für ein effizientes Verdunsten des Duftstoffs, so daß auch zwischen den einzelnen Spülvorgängen eine ausreichende Duftstoffmenge an die Umgebungsluft abgegeben wird. Im übrigen sorgt die Verteilerplatte für eine korrekte Do- sierung des Wirkstoffs für den nächsten Spülvorgang. In der Regel enthält der Wirkstoff ein Färbemittel zur Färbung des Spülwassers, wobei insbesondere eine Blaufärbung des Spülwassers erwünscht ist, was den Eindruck von Frische erweckt. Um zu verhindern, daß nach Abschluß des Spülvorgangs der Wirkstoff in das Toilettenbecken nachtropfen kann, was zu unerwünschten Verfärbungen des Toilettenbeckens führen würde, ist die Verteilerplatte von einer Wanne umfaßt, die sich über deren Oberkante erstreckt. Während des Spülvorgangs wird in der Regel das Spülwasser zusammen mit dem auf der Verteilerplatte befindlichen Wirkstoff oberseitig weggeschwemmt, so daß nur ein Teil des Spülwassers und des Wirkstoffs in die Wanne gelangt. Dies ist wichtig, um zu verhindern, daß nach Beendigung des Spülvorgangs Spülwasser auf der Verteilerplatte stehen bleibt. Gegebenenfalls ist es auch vorstellbar, daß das auf die Verteilerplatte auftreffende Spülwasser vollständig in die Wannndig in die Wanne gelangt. Die Wanne selbst weist mindestens einen Abfluß auf, damit sich diese wieder entleeren kann. Um ein unerwünschtes Nachtropfen der in der Wanne enthaltenen Flüssigkeit nach Beendigung des Spülvorgangs zu vermeiden, ist der Abfluß mit einem Siphon ausgerüstet, der erst ab einem bestimmten Füllstand der Wanne Flüssigkeit austreten läßt. Der Siphon ist dabei vorzugsweise derart ausgebildet, daß die Wanne nahezu vollständig entleert werden kann. Tropft anschließend von der Verteilerplatte Spülwasser bzw. Wirkstoff in die Wanne, so hält der Siphon diese Flüssigkeit bis zum nächsten Spülvorgang in der Wanne zurück. Auf diese Wiese werden unansehnliche Nachtropfspuren im Toilettenbecken zuverlässig verhindert. Um mit einfachen Mitteln sicherzustellen, daß die Wanne möglichst vollständig entleert wird, ist es gemäß Anspruch 2 vorteilhaft, wenn der Siphon einen Rohrstutzen aufweist, der unterseitig über den Wannenboden übersteht. Dieser Rohrstutzen erzeugt eine bestimmte Saugkraft auf die in der Wanne enthaltene Flüssigkeit, so daß diese bis zum tiefsten Punkt des Siphons entleert wird. Damit kann sich die Wanne anschließend beispielsweise durch von der Verteilerplatte tropfenden Wirkstoff bzw. Wasser bis zum höchsten Punkt des Siphons füllen, ohne daß Flüssigkeit aus dem Siphon austritt.The device according to claim 1 has a container which holds a liquid active substance. A liquid active substance has the advantage over a solid active substance that it is of constant quality and in particular concentration, so that its effect remains constant for the entire period of use. In particular, fragrances, cleaning agents, preferably in the form of surfactants and coloring agents, in particular blue coloring agents, are suitable as active ingredients. These active ingredients must be added to the rinse water in a certain dosage so that they can develop their optimal effect. For this purpose, the opening of the container is operatively connected to a distributor plate which distributes the active substance as evenly as possible over its surface. Particularly when fragrances are used as the active ingredient component, this areal distribution of the active ingredient ensures efficient evaporation of the fragrance, so that a sufficient amount of fragrance is released into the ambient air between the individual rinsing processes. In addition, the distributor plate ensures correct active ingredient for the next rinsing process. As a rule, the active ingredient contains a colorant for coloring the rinsing water, in particular a blue coloration of the rinsing water is desired, which gives the impression of freshness. In order to prevent the active substance from dripping into the toilet bowl after the flushing process has ended, which would lead to undesirable discoloration of the toilet bowl, the distributor plate is surrounded by a tub which extends over the upper edge thereof. During the rinsing process, the rinsing water is generally washed away along with the active ingredient on the distributor plate, so that only part of the rinsing water and the active ingredient get into the tub. This is important in order to prevent rinsing water from remaining on the distributor plate after the rinsing process has ended. If necessary, it is also conceivable that the rinsing water striking the distributor plate will completely enter the tub in the tub. The tub itself has at least one drain so that it can be emptied again. In order to avoid undesired dripping of the liquid contained in the tub after completion of the rinsing process, the drain is equipped with a siphon, which only lets liquid escape from a certain level in the tub. The siphon is preferably designed such that the trough can be almost completely emptied. If rinsing water or active ingredient then drips from the distributor plate into the tub, the siphon holds this liquid in the tub until the next rinsing process. In this way, unsightly dripping marks in the toilet bowl are reliably prevented. In order to ensure with simple means that the tub is emptied as completely as possible, it is advantageous according to claim 2 if the siphon has a pipe socket which projects beyond the bottom of the tub. This pipe socket creates a certain suction force on the liquid contained in the tub, so that it is emptied to the lowest point of the siphon. The trough can then be filled, for example, by the active ingredient or water dripping from the distributor plate up to the highest point of the siphon without liquid escaping from the siphon.
Grundsätzlich kann jede beliebige bekannte Siphonform genutzt werden. Um die Vorrichtung möglichst einfach und damit preisgünstig herstellen zu können, hat sich die Ausbildung des Siphons gemäß Anspruch 3 bewährt. Bei dieser Ausbildung taucht der Rohrstutzen von unten in den Wannenboden ein und ist von einer Glocke umfaßt. Diese Glocke besitzt bodennahe Öffnungen, so daß die in der Wanne enthaltene Flüssigkeit durch die Öffnungen in die Glocke eindringen kann. Die Öffnungen bilden dabei den tiefsten Punkt des Siphons. Ein Abfluß dieser Flüssigkeit ist jedoch erst dann möglich, wenn der Flüssigkeitspegel in der Wanne bis zum oberen Ende des Rohrstutzens reicht. Da das Spülwasser schwallartig ankommt, wird der Flüssigkeitspegel in der Wanne während des Spülvorgangs in der Regel wesentlich über das obere Ende des Rohrstutzens reichen, so daß die Glocke in diesem Fall vollständig mit der Flüssigkeit gefüllt ist. Dies gewährleistet in optimaler Weise eine nahezu vollständige Entleerung der Wanne. Bei dieser Ausgestaltung des Siphons kann der Rohr- stutzen gerade ausgebildet sein, was dessen Herstellung insbesondere im Spritzgußverfahren erheblich vereinfacht.In principle, any known siphon shape can be used. In order to be able to manufacture the device as simply and inexpensively as possible, the design of the siphon according to claim 3 has proven itself. In this design, the pipe socket is immersed in the bottom of the tub and is surrounded by a bell. This bell has openings near the bottom, so that the liquid contained in the tub can penetrate through the openings into the bell. The openings form the lowest point of the siphon. However, an outflow of this liquid is only possible when the liquid level in the tub extends to the upper end of the pipe socket. Since the rinsing water arrives like a surge, the liquid level in the tub will usually reach substantially above the upper end of the pipe socket during the rinsing process, so that the bell is completely filled with the liquid in this case. This ensures that the tub is almost completely emptied in an optimal manner. With this design of the siphon, the pipe be formed straight, which considerably simplifies its manufacture, particularly in the injection molding process.
Eine weitere Vereinfachung der Herstellung der Vorrichtung ergibt sich, wenn gemäß Anspruch 4 die Glocke einstückig an die Wanne angeformt ist. Damit entfallen Montageschritte zum Einbau der Glocke in die Wanne. Bei der Herstellung der Wanne im Spritzgußverfahren kann diese zusammen mit der Glocke gegebenenfalls ohne oder mit nur geringfügigen Hinterschneidungen ausgebildet sein, so daß bei deren Herstellung keinerlei Kerne gezogen werden müssen. Der Rohrstutzen wird in diesem Fall als gesondertes Teil erstellt und formschlüssig an der Wanne gehalten. Hierzu sind am den Rohrstutzen tragenden Teil und an der Wanne geringfügige Hinterschneidungen erforderlich, die jedoch spritzgußtechnisch unproblematisch sind.A further simplification of the manufacture of the device results if, according to claim 4, the bell is integrally formed on the tub. This eliminates assembly steps for installing the bell in the tub. In the manufacture of the tub by injection molding, this can be formed together with the bell, if necessary, with no or only slight undercuts, so that no cores have to be drawn during their manufacture. In this case, the pipe socket is created as a separate part and is held in a form-fitting manner on the tub. For this purpose, slight undercuts are required on the part supporting the pipe socket and on the tub, but these are not problematic in terms of injection molding.
Um die Wanne an der Verteilerplatte festzulegen, hat sich gemäß Anspruch 6 eine reibschlüssige Verbindung bewährt. Diese ist besonders einfach herzustellen, zumal keinerlei Hinterschneidungen erforderlich sind. In der Regel wird diese Verbindung durch sich daran ablagernden Wirkstoff zusätzlich verfestigt, so daß sich ohne weitere Maßnahmen eine feste Halterung der Wanne an der Verteilerplatte ergeben.In order to fix the tub to the distributor plate, a frictional connection has proven itself according to claim 6. This is particularly easy to manufacture, especially since no undercuts are required. As a rule, this connection is additionally solidified by the active substance deposited thereon, so that there is a firm mounting of the trough on the distributor plate without further measures.
Um der auf der Verteilerplatte befindlichen Flüssigkeit zu ermöglichen, in die Wanne zu gelangen, hat es sich gemäß Anspruch 7 bewährt, daß in der Verteilerplatte mindestens eine Durchbrechung vorgesehen ist. Vorzugsweise werden mehrere Durchbrechungen über die Verteilerplatte verteilt angeordnet, um einen effektiven Abfluß der Flüssigkeit in die Wanne zu gewährleisten.In order to enable the liquid on the distributor plate to get into the trough, it has proven itself according to claim 7 that at least one opening is provided in the distributor plate. Preferably several openings are made via the distributor plate distributed to ensure an effective drainage of the liquid into the tub.
Um zu verhindern, daß der Wirkstoff ungehindert in die Wanne abfließen kann, ist es gemäß Anspruch 8 günstig, wenn die Durchbrechung in der Verteilerplatte derart dimensioniert ist, daß sie vom Wirkstoff nur im durch das Spülwasser verdünnten Zustand passiert werden kann. Damit bleibt der auf der Verteilerplatte aufgebrachte Wirkstoff zwischen den Spülvorgängen erhalten, was insbesondere für im Wirkstoff enthaltene Duftstoffkomponenten wichtig ist.In order to prevent that the active ingredient can flow unhindered into the tub, it is advantageous according to claim 8 if the opening in the distributor plate is dimensioned such that the active ingredient can only pass through it in the state diluted by the rinse water. The active ingredient applied to the distributor plate is thus retained between the rinsing processes, which is particularly important for fragrance components contained in the active ingredient.
Alternativ oder zusätzlich ist es gemäß Anspruch 9 günstig, wenn zwischen der Wanne und der Verteilerplatte eine Öffnung gebildet ist, durch die der Wirkstoff bzw. das Spülwasser in die Wanne gelangen kann. Diese Öffnung ist bevorzugt im Eckbereich der Verteilerplatte angeordnet, so daß diese die Haltewirkung der Wanne an der Verteilerplatte nicht ungünstig beeinflussen kann.Alternatively or additionally, it is advantageous if an opening is formed between the tub and the distributor plate through which the active substance or the rinsing water can get into the tub. This opening is preferably arranged in the corner region of the distributor plate, so that it cannot adversely affect the holding effect of the trough on the distributor plate.
Damit sich eine reproduzierbare Menge des Wirkstoffs auf der Verteilerplatte möglichst gleichmäßig verteilt, ist es gemäß Anspruch 10 vorteilhaft, wenn die Verteilerplatte den Wirkstoff mittels Kapillarkanälen über deren Oberfläche verteilt. Beispielsweise ist daran gedacht, die Verteilerplatte aus porösem Material zu bilden, das den Wirkstoff wie ein Schwamm aufsaugt.So that a reproducible amount of the active ingredient is distributed as evenly as possible on the distributor plate, it is advantageous according to claim 10 if the distributor plate distributes the active ingredient over its surface by means of capillary channels. For example, it is contemplated to form the distributor plate from porous material that absorbs the active ingredient like a sponge.
Eine bevorzugte Ausbildung der Kapillarkanäle ergibt sich aus Anspruch 11. Dabei sind in die Oberfläche der Verteilerplatte Nuten bzw. Schlitze eingeformt, die die Kapi- larkanäle bilden. Dies hat den Vorteil, daß die Verteilerplatte aus dem gleichen Material wie die Wanne gefertigt werden kann, was die Herstellung der gesamten Vorrichtung erheblich vereinfacht.A preferred embodiment of the capillary channels results from claim 11. Grooves or slots are formed in the surface of the distributor plate which form lark channels. This has the advantage that the distributor plate can be made of the same material as the tub, which considerably simplifies the manufacture of the entire device.
Sind die Kapillarkanäle durch Schlitze der Verteilerplatte gebildet, so ist es gemäß Anspruch 12 günstig, wenn diese gleichzeitig die Durchbrechungen bilden, um den Wirkstoff bzw. das Spülwasser in die Wanne zu leiten. In diesem Fall kann auf zusätzliche Durchbrechungen der Verteilerplatte verzichtet werden.If the capillary channels are formed by slots in the distributor plate, then it is advantageous if these form the openings at the same time in order to guide the active substance or the rinsing water into the tub. In this case, additional openings in the distributor plate can be dispensed with.
Bei der Ausbildung der Kapillarkanäle in Form von Nuten der Verteilerplatte ist es gemäß Anspruch 13 zweckmäßig, die Durchbrechungen in der Verteilerplatte im Bereich zwischen den Nuten vorzusehen, um ein unkontrolliertes Abfließen des Wirkstoffs in die Wanne zu verhindern.When designing the capillary channels in the form of grooves in the distributor plate, it is expedient according to claim 13 to provide the openings in the distributor plate in the region between the grooves in order to prevent the active substance from flowing uncontrollably into the tub.
Schließlich ist es gemäß Anspruch 14 vorteilhaft, wenn die Verteilerplatte, die Wanne und/oder der Siphon aus einem thermoplastischen Polymer, insbesondere Polyethylen erstellt sind. Ein derartiger Polymer läßt sich sehr einfach im Spritzgußverfahren verarbeiten, was die Herstellung der Vorrichtung insgesamt kostengünstig macht.Finally, it is advantageous according to claim 14 if the distributor plate, the trough and / or the siphon are made of a thermoplastic polymer, in particular polyethylene. Such a polymer can be processed very easily by injection molding, which makes the manufacture of the device overall inexpensive.

Figur 2 eine Schnittdarstellung durch die Vorrichtung gemäß Figur 1.FIG. 2 shows a sectional view through the device according to FIG. 1.
Figur 3 eine vergrößerte Detailansicht der Schnittdarstellung gemäß Figur 2 undFigure 3 is an enlarged detail view of the sectional view of Figure 2 and
Figur 4 eine Ansicht einer alternativen Ausführungsform einer Vorrichtung von oben.Figure 4 is a top view of an alternative embodiment of a device.
Eine Vorrichtung 1 zur Abgabe des flüssigen Wirkstoffs 2 in ein Toilettenbecken gemäß Figur 1 weist einen Behälter 3 zur Aufnahme des flüssigen Wirkstoffs 2 auf. Der Behälter 3 besteht vorzugsweise aus einem transparenten Polymer, um den Flüssigkeitsstand des Wirkstoffs 2 im Behälter 3 leicht überprüfen zu können. Der Behälter 3 ist in einem Gehäuse 4 eingesteckt, das ein einfaches Auswechseln des Behälters 3 ermöglicht. Dies ist insbesondere dann erforderlich, wenn der Wirkstoff 2 im Behälter 3 verbraucht ist.A device 1 for dispensing the liquid active substance 2 into a toilet bowl according to FIG. 1 has a container 3 for holding the liquid active substance 2. The container 3 preferably consists of a transparent polymer in order to be able to easily check the liquid level of the active substance 2 in the container 3. The container 3 is inserted into a housing 4, which enables the container 3 to be replaced easily. This is particularly necessary when the active ingredient 2 in the container 3 has been consumed.
Die Vorrichtung 1 weist außerdem eine Verteilerplatte 5 auf, die den flüssigen Wirkstoff 2 aufnimmt und über deren Oberfläche möglichst gleichmäßig verteilt. Diese Verteilerplatte 5 besitzt eine Reihe von Kapillarkanälen 6, die in Form von Nuten 6 ausgebildet sind. Alternativ könnten die Kapillarkanäle 6 auch von die Verteilerplatte 5 vollständig durchsetzenden Schlitzen gebildet sein.The device 1 also has a distributor plate 5 which receives the liquid active substance 2 and distributes it as uniformly as possible over its surface. This distributor plate 5 has a series of capillary channels 6, which are designed in the form of grooves 6. alternative the capillary channels 6 could also be formed by slots which completely penetrate the distributor plate 5.
Um zu verhindern, daß auf der Verteilerplatte 5 befindlicher flüssiger Wirkstoff 2 bzw. Spülwasser nach dem Spülvorgang in das Toilettenbecken tropfen kann, ist die Verteilerplatte 5 innerhalb einer Wanne 7 angeordnet. Diese Wanne 7 kann grundsätzlich in beliebiger Weise geformt sein, wobei lediglich sichergestellt sein muß, daß die Wanne 7 eine Oberkante 8 der Verteilerplatte 5 allseitig überragt. Zusätzlich weist die Verteilerplatte 5 mehrere Durchbrechungen 9 auf, durch die auf der Verteilerplatte 5 befindliches Spülwasser, in dem teilweise der Wirkstoff 2 gelöst ist, in die Wanne 7 abfließen kann.In order to prevent liquid active substance 2 or flushing water located on the distributor plate 5 from dripping into the toilet bowl after the flushing process, the distributor plate 5 is arranged inside a tub 7. This trough 7 can in principle be shaped in any way, it only being necessary to ensure that the trough 7 projects over an upper edge 8 of the distributor plate 5 on all sides. In addition, the distributor plate 5 has a plurality of openings 9 through which rinsing water on the distributor plate 5, in which the active ingredient 2 is partially dissolved, can flow into the trough 7.
Um zu verhindern, daß die Wanne 7 durch ständige Aufnahme von Spülwasser und Wirkstoff 2 überläuft, ist diese mit einem Abfluß 10 versehen.In order to prevent the tub 7 from overflowing due to the constant absorption of rinsing water and active ingredient 2, it is provided with a drain 10.
Die weitere Beschreibung der Vorrichtung 1 erfolgt anhand der Schnittdarstellungen gemäß den Figuren 2 und 3. Der Abfluß 10 wird von einem Siphon 11 gebildet, durch den ein Nachtropfen des Wirkstoffs 2 aus der Wanne 7 nach Beendigung des Spülvorgangs verhindert werden soll. Dieser Siphon 11 wird von einem Rohrstutzen 12 und einer dessen oberes Ende 13 umfassenden Glocke 14 gebildet. Die Glocke 14 ist dabei einstückig an die Wanne 7 angeformt, um deren Herstellung zu vereinfachen. Zwischen der Glocke 14 und dem Wannenboden 15 befinden sich Öffnungen 16, die es der in der Wanne 7 befindlichen Flüssigkeit ermöglichen, in den Raum innerhalb der Glocke 14 einzudringen. Diese Öffnungen 16 sind in Höhe des Wannenbodens 15 angeordnet und sie bilden den tiefsten Punkt des Siphons 11. Damit ist gewährleistet, daß die Wanne 7 über den Siphon 11 vollständig entleert werden kann.The further description of the device 1 is based on the sectional representations according to FIGS. 2 and 3. The drain 10 is formed by a siphon 11, by means of which dripping of the active ingredient 2 from the tub 7 is to be prevented after the rinsing process has ended. This siphon 11 is formed by a pipe socket 12 and a bell 14 comprising its upper end 13. The bell 14 is integrally formed on the tub 7 to simplify its manufacture. Between the bell 14 and the trough bottom 15 there are openings 16 which allow the liquid in the trough 7 to penetrate into the space inside the bell 14. This Openings 16 are arranged at the level of the trough bottom 15 and form the lowest point of the siphon 11. This ensures that the trough 7 can be completely emptied via the siphon 11.
Das obere Ende 13 des Rohrstutzens 12 bildet den höchsten Punkt des Siphons, den die aus der Wanne 7 austretende Flüssigkeit überwinden muß. Der Rohrstutzen 12 erstreckt sich dabei über das untere Ende 17 des Siphons 11 hinaus, so daß beim Entleeren der Wanne 7 auf die darin enthaltende Flüssigkeit eine Kraft ausgeübt wird, die diese bis über das obere Ende 13 des Rohrstutzens 12 anhebt. Damit wird die Wanne 7 nach dem Spülvorgang nicht nur bis zur Oberkante 13 des Rohrstutzens 12, sondern bis zur Höhe der Öffnungen 16 der Glocke 14 und damit bis zum Wannenboden 15 entleert.The upper end 13 of the pipe socket 12 forms the highest point of the siphon, which the liquid emerging from the tub 7 must overcome. The pipe socket 12 extends beyond the lower end 17 of the siphon 11, so that when the trough 7 is emptied, a force is exerted on the liquid contained therein which lifts it up to the upper end 13 of the pipe socket 12. So that the tub 7 is emptied not only up to the upper edge 13 of the pipe socket 12, but up to the height of the openings 16 of the bell 14 and thus to the tub bottom 15 after the rinsing process.
Tropft anschließend weiterer Wirkstoff 2 durch die Durchbrechung 9 in die Wanne 7 hinein, so verhindert der Siphon 11 das Austreten dieser Flüssigkeit aus der Wanne 7. Erst wenn sich der Flüssigkeitspegel über das obere Ende 13 des Rohrstutzens 12 erstreckt, kann die Wanne 7 über den Siphon 11 wieder entleert werden. Ein Nachtropfen des Wirkstoffs 2 in das Toilettenbecken wird daher zwischen den Spülvorgängen zuverlässig verhindert.If further active ingredient 2 then drips through the opening 9 into the trough 7, the siphon 11 prevents this liquid from escaping from the trough 7. Only when the liquid level extends over the upper end 13 of the pipe socket 12 can the trough 7 pass over the Siphon 11 can be emptied again. Dripping of the active ingredient 2 into the toilet bowl is therefore reliably prevented between the flushing processes.
Aus der Figur 2 ist außerdem der Aufbau des Gehäuses 4 zu entnehmen. Am Gehäuse 4 ist ein Ring 18 angeformt, der einen Hals 19 des Behälters 3 umfaßt. Die Verbindung zwischen dem Ring 18 und dem Hals 19 ist dabei derart ausgebildet, daß zwischen beiden zwar Luft eintreten kann, um aus dem Behälter 3 entnommenen Wirkstoff 2 zu ersetzen, das Spülwasser jedoch vom Behälter 3 ferngehalten wird. Auf diese Weise wird verhindert, daß sich der Wirkstoff 2 im Behälter 3 durch eintretendes Spülwasser verdünnt.The structure of the housing 4 can also be seen from FIG. A ring 18 is formed on the housing 4 and comprises a neck 19 of the container 3. The connection between the ring 18 and the neck 19 is designed such that air can enter between them to replace active substance 2 removed from container 3, but the rinsing water is kept away from container 3. In this way it is prevented that the active ingredient 2 in the container 3 is diluted by rinsing water entering.
An der Verteilerplatte 5 ist ein Dorn 20 angeformt, der einen Verschluß 21 des Behälters 3 entlang einer Sollbruchstelle aufbricht. Auf diese Weise wird der Behälter 3 unmittelbar beim Einsetzen in das Gehäuse 4 geöffnet, wodurch ein versehentliches Austreten des Wirkstoffs 2 vor dem Einsetzen des Behälters 3 in das Gehäuse 4 verhindert wird. Der Verschluß 21 weist dabei eine Dichte auf, die geringer ist als die Dichte des Wirkstoffs 2, so daß dieser aufschwimmt und die gebildete Öffnung 22 des Behälters 3 nicht mehr behindern kann.A mandrel 20 is formed on the distributor plate 5 and breaks open a closure 21 of the container 3 along a predetermined breaking point. In this way, the container 3 is opened immediately upon insertion into the housing 4, thereby preventing the active ingredient 2 from inadvertently escaping before the container 3 is inserted into the housing 4. The closure 21 has a density that is less than the density of the active ingredient 2, so that it floats and can no longer hinder the opening 22 formed in the container 3.
Um die Verteilerplatte 5 am Gehäuse 4 festzulegen, weist die Verteilerplatte 5 Halteclips 23 auf, die in entsprechende Ausnehmungen des Gehäuses 4 eingreifen.In order to fix the distributor plate 5 on the housing 4, the distributor plate 5 has retaining clips 23 which engage in corresponding recesses in the housing 4.
Figur 4 zeigt eine alternative Ausführungsform der Vorrichtung 1 gemäß Figur 1 von oben, wobei gleiche Bezugszeichen gleiche Teile benennen. Bei dieser Ausführungsform ist die Verteilerplatte 5 derart geformt, daß sich in ihrem Eckbereich eine schlitzförmige Öffnung 24 bildet, durch die der Wirkstoff 2 bzw. das auf der Verteilerplatte 5 befindliche Spülwasser in die Wanne 7 gelangen kann.FIG. 4 shows an alternative embodiment of the device 1 according to FIG. 1 from above, the same reference symbols denoting the same parts. In this embodiment, the distributor plate 5 is shaped in such a way that a slot-shaped opening 24 is formed in its corner region, through which the active substance 2 or the rinsing water located on the distributor plate 5 can get into the tub 7.
Außerdem weist die Verteilerplatte 5 Kapillarkanäle 25 in Form von Schlitzen 25 auf, durch die der Wirkstoff 2 ent- lang der Verteilerplatte 5 verteilt wird. Diese Schlitze 25 sind derart ausgebildet, daß der unverdünnte Wirkstoff 2 in den Schlitzen 25 gehalten wird. Sobald der Wirkstoff 2 durch Spülwasser verdünnt ist, reicht dagegen die Kapillarwirkung der Schlitze 25 nicht mehr aus, so daß der Wirkstoff 2 in die Wanne 7 von dort über den Siphon 10 in das Toilettenbecken gelangt.In addition, the distributor plate 5 has capillary channels 25 in the form of slots 25 through which the active substance 2 long the distribution plate 5 is distributed. These slots 25 are designed such that the undiluted active substance 2 is held in the slots 25. As soon as the active ingredient 2 is diluted by rinsing water, the capillary action of the slots 25 is no longer sufficient, so that the active ingredient 2 enters the tub 7 from there via the siphon 10 into the toilet bowl.
