Description

Die vorliegende Erfindung betrifft ein WC-Körbchen zur Aufnahme von festen oder gelförmigen Zubereitungen.The present invention relates to a toilet basket for holding solid or gel-like preparations.

Stand der TechnikState of the art

Zur selbsttätigen Reinigung von Toilettenschüsseln ist es bekannt, Wirkstoffzubereitungen in stückiger Form in einem käfigartigen Behälter am Innenrand der Toilettenschüssel anzubringen. Bei jedem Spülvorgang löst sich ein Teil des Wirkstoffs im Spülwasser und wird zusammen mit dem Wasser in der Schüssel verteilt.For automatic cleaning of toilet bowls, it is known to apply active ingredient preparations in lump form in a cage-like container on the inner edge of the toilet bowl. With each rinsing process, part of the active ingredient dissolves in the rinse water and is distributed together with the water in the bowl.

Es werden derartige Wirkstoffzubereitungen eingesetzt, die einerseits zu formbeständigen, nicht zerfließenden Blöcken geformt werden können und andererseits eine ausreichende Löslichkeit besitzen, so dass während der kurzen Spülphase eine ausreichende Menge an Wirkstoffen an das Wasser abgegeben wird. Wichtig ist außerdem, dass der Wirkstoffblock nach dem Spülvorgang, abgesehen von einer Duftabgabe, unverändert bleibt.Active ingredient preparations of this type are used which, on the one hand, can be formed into dimensionally stable, non-deliquescent blocks and, on the other hand, have sufficient solubility so that a sufficient amount of active ingredients is released into the water during the short rinsing phase. It is also important that the active ingredient block remains unchanged after the rinsing process, with the exception of a fragrance release.

Ein Beispiel für eine derartige Wirkstoffzubereitung findet sich in der DE 34 24 317 A1 . Die Zubereitung enthält anionische und nichtionische Tenside, Parfüm, Cellulosepulver, Abspülregulatoren, anorganische Salze, Komplexbildner, kalksteinlösende Säuren, antimikrobielle Wirkstoffe, Plastifikatoren und weitere übliche Zusätze.An example of such an active ingredient preparation can be found in DE 34 24 317 A1 . The preparation contains anionic and nonionic surfactants, perfume, cellulose powder, rinsing regulators, inorganic salts, complexing agents, acids that dissolve limescale, antimicrobial agents, plasticizers and other common additives.

Bekannt sind einmalig verwendbare WC-Körbchen, die nach dem vollständigen Auflösen des Wirkstoffblocks entsorgt werden müssen. Günstiger im ökologischen Sinne sind die ebenfalls bekannten nachfüllbaren WC-Körbchen, von denen zwei in der DE 80 01 994 U1 und der DE 34 23 758 A1 beschrieben werden.One-time use toilet baskets that have to be disposed of after the active substance block has completely dissolved are known. The well-known refillable toilet baskets, two of which are in the, are cheaper in the ecological sense DE 80 01 994 U1 and the DE 34 23 758 A1 to be discribed.

Die bekannten WC-Körbchen zur Aufnahme stückiger WC-Reinigungsblöcke sind für Pasten oder Flüssigkeiten üblicherweise nicht einsetzbar. Die Paste bzw. Flüssigkeit soll nämlich nach Beendigung des Spülvorgangs nicht selbsttätig aus dem Körbchen ausfließen oder heraustropfen. Bei jedem Spülvorgang soll außerdem nur ein definierter Bruchteil der Flüssigkeit bzw. Paste abgegeben werden. Dieser abgegebene Bruchteil der Wirkstoffzubereitung soll bei jedem Spülvorgang möglichst gleich sein. Derartige WC-Körbchen für pastöse oder flüssige Zubereitungen sind beispielsweise aus DE19520145A1 oder aus EP1334239B1 bekannt.The known toilet baskets for holding lumpy toilet cleaning blocks cannot usually be used for pastes or liquids. The paste or liquid should not automatically flow or drip out of the basket after the flushing process has ended. In addition, only a defined fraction of the liquid or paste should be dispensed with each flushing process. This released fraction of the active ingredient preparation should be the same as possible in each rinsing process. Such toilet baskets for pasty or liquid preparations are made, for example DE19520145A1 or off EP1334239B1 known.

Auch sind im Stand der Technik Mehrkammerbehältnisse für die eingangs beschriebenen Wirkstoffzubereitungen bekannt, die derart in das WC-Becken gehangen werden, dass beim Spülvorgang des WC-Beckens mit Wasser eine Wirkstoffabgabe aus dem WC-Körbchen in das Toilettenbecken erfolgt. Durch die ungleichmäßigen Strömungsbedingungen innerhalb des Spülwasserflusses kann es, je nach Positionierung des WC-Körbchens am Rand des Toilettenbeckens, zu einer ungleichmäßigen Entleerung der Kammern kommen.Also known in the prior art are multi-chamber containers for the active ingredient preparations described at the beginning, which are hung in the toilet bowl in such a way that when Rinsing of the toilet bowl with water takes place an active ingredient is released from the toilet basket into the toilet bowl. The uneven flow conditions within the flushing water flow can result in uneven emptying of the chambers, depending on the positioning of the toilet basket on the edge of the toilet bowl.

DE 10 2009 003 088 A2 offenbart ein WC-Körbchen gemäß des Oberbegriffs des Anspruchs 1. DE 10 2009 003 088 A2 discloses a toilet basket according to the preamble of claim 1.

Ein wesentlicher Nachteil all dieser WC-Körbchen ist dass die Wirkstofffreisetzung durch den Benutzer nicht gesteuert werden kann. Es besteht jedoch ein regelmäßiges Bedürfnis für Benutzer, die Menge an Wirkstoffen und somit die Intensität der Reinigungs- bzw. Beduftungsleistung eines WC-Körbchens auf einfache Weise beeinflussen zu können.A major disadvantage of all of these toilet baskets is that the release of active ingredient cannot be controlled by the user. However, there is a regular need for users to be able to easily influence the amount of active ingredients and thus the intensity of the cleaning or scenting performance of a toilet basket.

Aufgabe der vorliegenden Erfindung ist es daher die aufgezeigten Nachteile zu vermeiden und einen WC-Körbchen bereitzustellen, bei dem die Menge an Wirkstoffen und somit die Intensität der Reinigungs- bzw. Beduftungsleistung eines WC-Körbchens auf einfache Weise durch einen Benutzer beeinflussbar sind.The object of the present invention is therefore to avoid the disadvantages mentioned and to provide a toilet basket in which the amount of active ingredients and thus the intensity of the cleaning or scenting performance of a toilet basket can be easily influenced by a user.

Diese Aufgabe wird durch ein WC-Körbchen mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a toilet basket with the features of claim 1.

Das erfindungsgemäße WC-Körbchen zur Aufnahme von festen oder gelförmigen Zubereitungen umfasst eine Mehrzahl von - bezogen auf die Längsmittelachse M des WC-Körbchens - in Reihe zueinander angeordneten Behältern zur Aufnahme mindestens einer Zubereitung, wobei die Behälter derart unterhalb des Toilettenrandes positionierbar sind, dass sie beim Spülen der Toilette von Spülwasser überströmbar und jeweils mindestens eine Einlassöffnung und eine Auslassöffnung in der Behälterwand für das Spülwasser ausgeformt ist, einen Halter zum Befestigen des WC-Körbchens am Toilettenrand, wobei am WC-Körbchen ein Spülwasserleitelement derart angeordnet und konfiguriert ist, dass das Spülwasserleitelement von Spülwasser beim Spülen beaufschlagt und eine Zuführung des Spülwassers zu den Einlassöffnung des Behälters bewirkt ist, wobei die Einlassöffnungen asymmetrisch bezüglich der Vertikalachse V der Behälter und in einem Anstellwinkel α zur Längsmittelachse M von 1°-60°, bevorzugt 5°-45°, insbesondere bevorzugt 10°-30° angeordnet sind.The toilet basket according to the invention for holding solid or gel-like preparations comprises a plurality of containers arranged in a row with respect to the longitudinal center axis M of the toilet basket for holding at least one preparation, the containers being positionable below the toilet rim in such a way that they flushing water can flow over when the toilet is flushed and at least one inlet opening and one outlet opening are formed in the container wall for the flushing water, a holder for attaching the toilet basket to the toilet rim, a flushing water guide element being arranged and configured on the toilet basket in such a way that the Rinsing water guide element acted upon by rinsing water during rinsing and the rinsing water is supplied to the inlet opening of the container, the inlet openings being asymmetrical with respect to the vertical axis V of the container and at an angle of incidence α to the longitudinal center axis M of 1 ° -60 °, preferably 5 ° -45 ° , in particular preferably 10 ° -30 ° are arranged.

Durch die erfindungsgemäße asymmetrische Anordnung der Spülwassereinlassöffnungen sowie der gewinkelten Anstellung der Behälter des WC-Körbchens können zwei unterschiedliche Wirkstoffabgabemengen aus dem WC-Spüler realisiert werden, indem der WC-Spüler einfach durch den Benutzer an sich gegenüberliegenden Seiten des Toilettenbeckens positioniert wird. Dies wird nachfolgend noch näher erläutert.Due to the inventive asymmetrical arrangement of the flushing water inlet openings and the angled positioning of the toilet basket container, two different amounts of active ingredient can be released from the toilet freshener by simply positioning the toilet freshener on opposite sides of the toilet bowl by the user. This is explained in more detail below.

Behältercontainer

Unter einem Behälter wird ein Verpackungsmittel verstanden, das dazu geeignet ist, eine feste, flüssige oder gelförmige Zubereitung zumindest teilweise zu umhüllen und/oder zusammenzuhalten.A container is understood to mean a packaging means which is suitable for at least partially enveloping and / or holding together a solid, liquid or gel-like preparation.

Das erfindungsgemäße WC-Körbchen besteht aus einer Mehrzahl an Behältern wobei diese nebeneinander, in Reihe zueinander, angeordnet sindThe toilet basket according to the invention consists of a plurality of containers, these being arranged next to one another, in series with one another

Des Weiteren ist mehr als ein Behälter zur Aufnahme einer Zubereitung oder voneinander verschiedener Zubereitungen am WC-Körbchen vorgesehen. Hierdurch können insbesondere nicht miteinander lagerstabile Zubereitungen räumlich voneinander getrennt bevorratet werden. Es ist jedoch auch prinzipiell denkbar, insbesondere bei festen Zubereitungen, voneinander verschiedene Zubereitungen nebeneinander in einem Behälter von der Mehrzahl der Behälter zu positionieren.Furthermore, more than one container is provided on the toilet basket to hold a preparation or preparations that differ from one another. As a result, preparations that are not stable to one another can in particular be stored spatially separated from one another. In principle, however, it is also conceivable, in particular in the case of solid preparations, to position preparations that are different from one another next to one another in one of the plurality of containers.

In diesem Zusammenhang ist es vorteilhaft die Behälter derart auszubilden, dass ein Austausch von eingetretenem Spülwasser zwischen den Behältern verhindert ist.In this context, it is advantageous to design the containers in such a way that an exchange of flushing water that has entered between the containers is prevented.

Die Mehrzahl von Behältern können einstückig miteinander verbunden sein. Dies hat insbesondere den Vorteil, dass die Behälter einstückig, beispielsweise in einem Spritzgussprozess, geformt werden können und ein nachträgliches Zusammenfügen von einzelnen Behältern entfällt. Bei einer derartigen Ausbildung der Behälter ist es des Weiteren vorteilhaft, die Behälter als Halbschalen auszubilden, welche durch eine Materialbrücke miteinander in Verbindung stehen. Die Materialbrücke dient dabei als Scharnier, um das die Halbschalen gekippt und zu einem oder einer Mehrzahl von Behältern gefügt werden können.The plurality of containers can be integrally connected to one another. This has the particular advantage that the containers can be formed in one piece, for example in an injection molding process, and there is no need to subsequently join individual containers together. With such a design of the containers, it is also advantageous to design the containers as half-shells which are connected to one another by a material bridge. The material bridge serves as a hinge around which the half-shells can be tilted and joined to form one or a plurality of containers.

Die Behälter können in einer Ausgestaltung der Erfindung über einen nicht wasserführenden Steg miteinander verbunden sein. Hierdurch lassen sich insbesondere formstabile Behälter ausbilden, die einen hinreichenden mechanischen Schutz der in ihnen bevorrateten Zubereitungen bereitstellen, wobei durch die Stege eine elastische Verbindung zwischen den Behältern ausbildbar ist, so dass das WC-Körbchen im eingesetzten Zustand der Kontur des Toilettenbeckens folgt.In one embodiment of the invention, the containers can be connected to one another via a web that does not carry water. In this way, in particular, dimensionally stable containers can be formed which provide sufficient mechanical protection for the preparations stored in them, with the webs being able to form an elastic connection between the containers so that the toilet basket follows the contour of the toilet bowl when inserted.

Insbesondere für feste und gelförmige Zubereitungen ist der Behälter von Spülwasser durchströmbar ausgebildet, d.h. er weist zumindest eine Einlassöffnung für den Eintritt von Spülwasser in den Behälter und wenigstens eine Auslassöffnung zum Austritt von mit Zubereitung beladenem Spülwasser aus dem Behälter auf.In particular for solid and gel-like preparations, the container is designed so that rinsing water can flow through it, ie it has at least one inlet opening for the entry of rinsing water into the container and at least one outlet opening for the exit of rinsing water loaded with preparation from the container.

In einer vorteilhaften Ausbildung des erfindungsgemäßen WC-Körbchens liegen die Einlassöffnungen der Behälter im in der Toilette eingebauten Zustand des WC-Körbchens außerhalb des Spülwasserstroms. D.h. dass ohne Verwendung des Spülwasserleitelements kein oder zumindest nur eine sehr geringe Menge an Spülwasser durch die Einlassöffnungen in die Behälter eintritt.In an advantageous embodiment of the toilet basket according to the invention, when the toilet basket is installed in the toilet, the inlet openings of the containers are outside the flow of flushing water. I.e. that without the use of the flushing water guide element, no or at least only a very small amount of flushing water enters the container through the inlet openings.

Auch ist es vorteilhaft, die Einlassöffnungen schlitzartig parallel zur Längsachse des WC-Körbchens auszubilden.It is also advantageous to design the inlet openings in a slot-like manner parallel to the longitudinal axis of the toilet basket.

ZubereitungenPreparations

Feste Zubereitungen, welche auch gewöhnlich als Toilettensteine bezeichnet werden, werden überwiegend als gepresste Formkörper, als Extrudate oder mittels Gießverfahren hergestellt. Es ist auch denkbar derartige Formkörper zumindest teilweise aus einer gelförmigen oder flüssigen Phase auszubilden. So kann beispielsweise der Kern eines Toilettensteins aus einem Gel bestehen, das in einer Kavität des Toilettensteins z.B. durch Kleben fixiert ist.Solid preparations, which are also commonly referred to as toilet blocks, are mainly produced as pressed moldings, as extrudates or by means of casting processes. It is also conceivable to form such shaped bodies at least partially from a gel-like or liquid phase. For example, the core of a toilet block can consist of a gel that is deposited in a cavity of the toilet block, e.g. is fixed by gluing.

Üblicherweise haben Toilettensteine heute eine zylindrische oder balkenartige Form. Es ist jedoch denkbar und wünschenswert, Formen bereitzustellen, die sich von diesen traditionellen Formen abgrenzen, wodurch eine größere Eigenständigkeit eines entsprechenden Produkts beim Verbraucher erzielt werden kann. Insbesondere können die festen Zubereitungen daher kugel oder zylinderartig ausgebildet sein. Zubereitungen für ein erfindungsgemäßes WC-Körbchen enthalten üblicherweise Substanzen wie z.B. Reinigungssubstanzen, Enzyme, Parfümöle, Farbstoffe, Tenside oder Schaumbildner. Insbesondere kann es sich hierbei um natürliche Parfümöle, Farbstoffe und Tenside handeln. Die Zubereitung weist bevorzugt einen Tensidgehalt von 2-50 Gew-% und/oder einen Parfümölgehalt von 1-20 Gew-% und/oder einen Farbstoffgehalt von 0,5-20 Gew-% auf. In einer besonders bevorzugten Ausführungsform umfasst die Zubereitung wenigstens ein Enzym in einer Konzentration von 0,1 bis 10 Gew-% auf.Usually, toilet blocks today have a cylindrical or bar-like shape. However, it is conceivable and desirable to provide shapes that differ from these traditional shapes, as a result of which a corresponding product can be achieved more independently for the consumer. In particular, the solid preparations can therefore have a spherical or cylindrical shape. Preparations for a toilet basket according to the invention usually contain substances such as e.g. Cleaning substances, enzymes, perfume oils, dyes, surfactants or foaming agents. In particular, these can be natural perfume oils, dyes and surfactants. The preparation preferably has a surfactant content of 2-50% by weight and / or a perfume oil content of 1-20% by weight and / or a dye content of 0.5-20% by weight. In a particularly preferred embodiment, the preparation comprises at least one enzyme in a concentration of 0.1 to 10% by weight.

Es ist besonders bevorzugt, dass ein Toilettenstein wenigstens einen ersten wasserlöslichen Grundkörper sowie wenigstens eine den Grundkörper zumindest teilweise überdeckenden, äußeren, wasserlöslichen Schicht umfasst. Ganz besonders bevorzugt ist es, wenn die äußere Schicht vom Grundkörper verschiedene optische Eigenschaften aufweist, wie beispielsweise Farbe und/oder Glanz. Hierdurch ist es möglich, eine Indikatorfunktion für den Benutzer bereitzustellen, welche nach einigen Spülgängen anzeigt, wie gleichmäßig die jeweiligen Toilettensteine im WC-Körbchen von Wasser überströmt und beaufschlagt sind, um evtl. eine andere Positionierung des WC-Spülers im Toilettenbecken vornehmen zu können.It is particularly preferred that a toilet block comprises at least one first water-soluble base body and at least one outer, water-soluble layer which at least partially covers the base body. It is very particularly preferred if the outer layer has different optical properties from the base body, such as color and / or gloss. This makes it possible to provide the user with an indicator function which, after a few flushes, shows how evenly the respective toilet blocks in the toilet basket are overflowing and exposed to water, in order to be able to position the toilet flush in the toilet bowl.

Die äußere Schicht des Toilettensteins weist bevorzugt eine Dicke zwischen 10-1.000 µm, besonders bevorzugt 20-500 µm, ganz besonders bevorzugt 50-150 µm auf. Bevorzugt umschließt die Schicht den Grundkörper vollständig.The outer layer of the toilet block preferably has a thickness between 10-1,000 μm, particularly preferably 20-500 μm, very particularly preferably 50-150 μm. The layer preferably completely encloses the base body.

Bevorzugte Toilettensteine sind des Weiteren dadurch gekennzeichnet, daß der Grundkörper ein Granulat und/oder ein Extrudat und/oder ein Pellet und/oder ein Prill und/oder ein schmelzgegossener Formkörper und/oder eine Tablette ist.Preferred toilet blocks are further characterized in that the base body is a granulate and / or an extrudate and / or a pellet and / or a prill and / or a melt-cast molded body and / or a tablet.

Halterholder

Das erfindungsgemäße WC-Körbchen umfasst einen Halter zum Befestigen des WC-Körbchens am Beckenrand einer Toilette.The toilet basket according to the invention comprises a holder for fastening the toilet basket to the edge of the toilet bowl.

Üblicherweise sind derartige Halter als stabförmiges Element mit zwei Schleifen ausgebildet, so dass durch die Federwirkung der Schleifen der Halter mit dem WC-Körbchen am Rand der Toilette geklemmt werden kann.Such holders are usually designed as a rod-shaped element with two loops, so that the holder with the toilet basket can be clamped on the edge of the toilet by the spring action of the loops.

In einer vorteilhaften Weiterentwicklung der Erfindung umfasst der Halter wenigstens ein Federelement, das im in der Toilette eingebauten Zustand des WC-Spülers einen im Wesentlichen vertikalen oder horizontalen Federweg aufweist. Ferner ist es ganz besonders bevorzugt, dass der Halter wenigstens zwei Federelemente aufweist, wobei im in der Toilette eingebauten Zustand des WC-Spülers ein Federelement einen im Wesentlichen vertikalen Federweg und ein Federelement einen im Wesentlichen horizontalen Federweg aufweist. Durch den bereitgestellten Federweg wird eine verbesserte und flexiblere Fixierung des WC-Körbchens an Toiletten mit unterschiedlichen Beckenrandstärken und -ausgestaltungen ermöglicht. Insbesondere kann das Federelement rautenförmig ausgebildet sein.In an advantageous further development of the invention, the holder comprises at least one spring element which, when the toilet freshener is installed in the toilet, has an essentially vertical or horizontal spring travel. Furthermore, it is very particularly preferred that the holder has at least two spring elements, with one spring element having an essentially vertical spring deflection and one spring element having an essentially horizontal spring deflection when the toilet freshener is installed in the toilet. The spring travel provided enables an improved and more flexible fixation of the toilet basket on toilets with different pool rim thicknesses and configurations. In particular, the spring element can be designed in a diamond shape.

Fig. 1 zeigt eine Ausführungsform des erfindungsgemäßen WC-Körbchens 1 in im Toilettenbecken 9 eingehangenem Zustand, wobei das WC-Körbchen 1 mittels des Halters 2 am Toilettenbecken 9 lösbar fixiert ist. Fig. 1 shows an embodiment of the toilet basket 1 according to the invention in the state suspended in the toilet bowl 9, the toilet basket 1 being releasably fixed on the toilet bowl 9 by means of the holder 2.

Das WC-Körbchen 1 besteht aus vier in einer Reihe angeordneten Behältern 3a, 3b, 3c, 3d welche zylinderförmig ausgebildet sind und welche jeweils eine feste WC-Reinigungszusammensetzung 4a,4b,4c,4d bevorraten. Auf der vom Toilettenbecken 9 abgewandet Seite des WC-Körbchens 1 sind die Auslassöffnungen 6a,6b,6c,6d der Behälter 3a,3b,3c,3d angeordnet.The toilet basket 1 consists of four containers 3a, 3b, 3c, 3d arranged in a row, which are cylindrical and which each store a solid toilet cleaning composition 4a, 4b, 4c, 4d. On the side of the toilet basket 1 facing away from the toilet bowl 9, the outlet openings 6a, 6b, 6c, 6d of the containers 3a, 3b, 3c, 3d are arranged.

Das WC-Körbchen 1 ist so konfiguriert, dass das Spülwasserleitelement 8 (nicht sichtbar) in im Toilettenbecken 9 eingehangenem Zustand unterhalb des Toilettenrandes 10 angeordnet ist.The toilet basket 1 is configured in such a way that the flushing water guide element 8 (not visible) is arranged below the toilet rim 10 when it is suspended in the toilet bowl 9.

Fig. 2 zeigt das Fig. 1 bekannte WC-Körbchen 1 in einer perspektivischen, auf die im in der Toilette 9 eingehangenen Zustand zum Toilettenbecken hin gerichteten Ansicht. Fig. 2 shows that Fig. 1 known toilet basket 1 in a perspective view directed towards the toilet bowl when it is suspended in the toilet 9.

Die Behälter 3a,3b,3c,3d sind zylinderförmig ausgebildet, wobei deren Rotationsachse senkrecht zur Vertikalachse V angeordnet ist. Die Behälter 3a,3b,3c,3d sind linienartig nebeneinander angeordnet.The containers 3a, 3b, 3c, 3d are cylindrical, their axis of rotation being perpendicular to the vertical axis V. The containers 3a, 3b, 3c, 3d are arranged in a line next to one another.

An den zylinderförmigen Behälter 3a,3b,3c,3d ist in etwa horizontal mittig das Spülwasserleitelement 8 über die gesamte Länge des WC-Körbchens 1 angeordnet. Das Spülwasserleitelement 8 ist plattenartig ausgebildet. Oberhalb des Spülwasserleitelements 8 sind in den Behältern 3a,3b,3c,3d Einlassöffnungen 5a,5b,5c,5d für Spülwasser vorgesehen, welches durch das Spülwasserleitelement 8 den Einlassöffnungen 5a,5b,5c,5d zugeführt wird.On the cylindrical container 3a, 3b, 3c, 3d, the flushing water guide element 8 is arranged approximately horizontally in the center over the entire length of the toilet basket 1. The flushing water guide element 8 is designed in the manner of a plate. Inlet openings 5a, 5b, 5c, 5d for flushing water are provided in the containers 3a, 3b, 3c, 3d above the flushing water guide element 8, which is supplied to the inlet openings 5a, 5b, 5c, 5d through the flushing water guide element 8.

Die Einlassöffnungen 5a,5b,5c,5d sind asymmetrisch bezüglich der Vertikalachse V an den Behältern 3a,3b,3c,3d angeordnet. Ferner sind die Behältern 3a,3b,3c,3d mit den jeweiligen Einlassöffnungen 5a,5b,5c,5d in einem Anstellwinkel α zur Längsmittelachse M von 1°-60°, bevorzugt 5°-45°, insbesondere bevorzugt 10°-30° angeordnet. Die Einlassöffnungen 5a,5b,5c,5d sind schlitzförmig, parallel zum Spülwasserleitelement 8 ausgebildet.The inlet openings 5a, 5b, 5c, 5d are arranged asymmetrically with respect to the vertical axis V on the containers 3a, 3b, 3c, 3d. Furthermore, the containers 3a, 3b, 3c, 3d with the respective inlet openings 5a, 5b, 5c, 5d are at an angle of incidence α to the longitudinal center axis M of 1 ° -60 °, preferably 5 ° -45 °, particularly preferably 10 ° -30 ° arranged. The inlet openings 5a, 5b, 5c, 5d are slot-shaped, parallel to the flushing water guide element 8.

Bei Betätigung der WC-Spülung trifft Spülwasser, welches üblicherweise mit einer gerichteten Verwirblung in das Toilettenbecken gespült wird, mit einer Strömungsrichtungskomponente, welche parallel zum Spülwasserleitelement 8 verläuft, auf den WC-Spüler 1. Im gezeigten Beispiel der Fig. 2 ist dies durch den Pfeil angedeutet.When the toilet flush is actuated, flushing water, which is usually flushed into the toilet bowl with a directed swirl, meets the toilet freshener 1 with a flow directional component that runs parallel to the flushing water guide element 8 Fig. 2 this is indicated by the arrow.

Durch die asymmetrische Anordnung der Einlassöffnungen 5a,5b,5c,5d und die angestellte Ausrichtung der Behälter 3a,3b,3c,3d gelangt unterschiedlich viel Spülwasser in die Einlassöffnungen 5a,5b,5c,5d, je nachdem aus welcher Richtung das Spülwasser auf den WC-Spüler 1 auftrifft. Mit der Spülwasserrichtungsabhängigen Beaufschlagung der Behälter 3a,3b,3c,3d mit Spülwasser erfolgt auch eine unterschiedlich starke Wirkstofffreisetzung aus dem WC-Spüler.Due to the asymmetrical arrangement of the inlet openings 5a, 5b, 5c, 5d and the adjusted alignment of the containers 3a, 3b, 3c, 3d, different amounts of rinse water get into the inlet openings 5a, 5b, 5c, 5d, depending on the direction from which the rinse water reaches the Toilet freshener 1 hits. When the containers 3a, 3b, 3c, 3d are subjected to flushing water, depending on the direction of the flushing water, there is also a different degree of active ingredient release from the toilet freshener.

Diese Funktionsweise wird anhand von Fig. 3 näher erläutert. Fig. 3 zeigt zwei unterschiedliche Fixierungspositionen des erfindungsgemäßen WC-Körbchens 1 in einem Toilettenbecken 9, welche typischerweise vom Benutzer zur Fixierung von WC-Körbchen 1 am Toilettenbecken 9 gewählt werden.This functionality is demonstrated using Fig. 3 explained in more detail. Fig. 3 shows two different fixing positions of the toilet basket 1 according to the invention in a toilet bowl 9, which are typically selected by the user for fixing the toilet basket 1 on the toilet bowl 9.

Wird das aus Fig. 2 bekannte WC-Körbchen 1 wie in der linken Abbildung der Fig. 3 gezeigt, an der linken Seite des Toilettenrandes 9 befestigt, so wird, wenn der Spülwasserstrom eine Verwirblungsbewegung in Richtung des in Fig. 2 gezeigten Pfeils aufweist, vergleichsweise geringe Spülwassermengen in das WC-Körbchen 1 eindringen, da durch die Anstellung der Behälter 3a,3b,3c,3d der Spülwasserstrom in großen Teilen parallel zu den schlitzförmigen Einlassöffnungen 5a,5b,5c,5d verläuft. Wird hingegen das WC-Körbchen 1 an der rechten Seite des Toilettenbeckens 9 fixiert, wie es in der rechten Abbildung von Fig. 3 gezeigt ist, so trifft der Spülwasserstrom nicht mit der in Fig. 2 gezeigten Richtung auf das WC-Körbchen 1, sondern in genau der entgegen gesetzten Richtung. In diesem Fall wird durch die Anstellung der Behälter 3a,3b,3c,3d sowie die asymmetrische Ausbildung der Einlassöffnungen 5a,5b,5c,5d der Spülwasserstrom direkt auf die Einlassöffnungen 5a,5b,5c,5d zugeleitet, wodurch vergleichsweise große Spülwassermengen in das WC-Körbchen eintreten können. Durch diese, für den Benutzer einfach vorzunehmende Positionsvariation an einer Toilette, ist es dem Benutzer somit durch das erfindungsgemäße WC-Körbchen ermöglicht, den Grad der Produktfreisetzung aus dem WC-Spüler zu steuern.Will that turn out Fig. 2 well-known toilet basket 1 as in the left figure of the Fig. 3 shown, attached to the left side of the toilet rim 9, so when the flushing water flow swirls in the direction of the in Fig. 2 shown arrow, comparatively small amounts of flush water penetrate into the toilet basket 1, since the adjustment of the containers 3a, 3b, 3c, 3d, the flushing water flow in large parts parallel to the slot-shaped inlet openings 5a, 5b, 5c, 5d. If, on the other hand, the toilet basket 1 is fixed on the right-hand side of the toilet bowl 9, as shown in the right-hand illustration of FIG Fig. 3 is shown, the flush water flow does not meet the in Fig. 2 direction shown on the toilet basket 1, but in exactly the opposite direction. In this case, the adjustment of the containers 3a, 3b, 3c, 3d and the asymmetrical design of the inlet openings 5a, 5b, 5c, 5d lead to the flushing water flow directly to the inlet openings 5a, 5b, 5c, 5d, which means that comparatively large amounts of flushing water are fed into the Toilet basket can enter. As a result of this position variation on a toilet, which is easy for the user to undertake, the toilet basket according to the invention enables the user to control the degree of product release from the toilet freshener.
