Description

Die Erfindung betrifft eine Abgabevorrichtung zur Abgabe eines Wirkstofffluids in die Spülflüssigkeit in einem Toilettenbecken mit den Merkmalen des Oberbegriffs von Anspruch 1.The invention relates to a delivery device for delivering a drug fluid in the rinsing liquid in a toilet bowl with the features of the preamble of claim 1.

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 in der DE 199 30 362 A1, sowie in der EP 0 775 741 A 1 und der EP 0 960 984 A2).The term active ingredient fluid means flowable, that is liquid to viscous, possibly gelatinous or also pasty or granular or otherwise free-flowing Active substance preparations with cleansing, disinfecting, deodorizing, bleaching etc. Effect (in particular described in DE 199 30 362 A1, as well in EP 0 775 741 A1 and 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 angeordneten Auslaßöffnung.Dispensers of the type in question are under the keyword "toilet bowl" known in different versions. First, dispensing devices are known for a single drug fluid. The drug fluid is located There in a fixed in a holder or used interchangeably Reservoir with a mounted on the holder reservoir bottom side arranged outlet.

Bei einer ersten bekannten Abgabevorrichtung für ein einzelnes Wirkstoffluid 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 Heraussickem des Wirkstofffluids zur Verfügung steht. Die Vorrichtung funktioniert unter Nutzung der Kapillarwirkung des offenporigen Schaumstoffs.In a first known single agent fluid delivery device the active substance fluid via a soakable, acted upon by the rinsing liquid Actuating element (eg., From an open-cell foam) added (EP 785 315 A1). Here is the outlet of the reservoir after Pushing out a closure part of the reservoir from one to the holder fixedly arranged sealing element largely closed, so that only still a flow path with a small cross-section to heraussickem of Drug fluids is available. The device works under use the capillary action of the open-celled foam.

Eine der zuvor erläuterten Abgabevorrichtung ähnliche Abgabevorrichtung mit einer der Verteilung des Wirkstofffluids in der Spülflüssigkeit dienenden Rippenplatte ist ebenfalls bekannt (DE 199 12 217 A1; WO 99/66140 A). Bei dieser Konstruktion weist der Vorratsbehälter eine von einem ringförmigen Rand umschlossene Auslaßöffnung auf, über die das Wirkstofffluid in die Spülflüssigkeit abgebbar ist. Am Halter ist ein plattenartiges Verteilungselement vorgesehen, das einerseits einen beim Spülvorgang von Spülflüssigkeit überströmten Beaufschlagungsbereich und andererseits einen Anschlußbereich aufweist, in dem eine Aufstechspitze angeordnet ist. Das Innere des Vorratsbehälters steht über die Auslaßöffnung unter Zwischenschaltung der ein freies fließendes Wirkstofffluids verhindernden Aufstoßspitze mit seitlichen Rippen dauernd mit dem Verteilungselement in Verbindung. Dazu ist der Rand der Auslaßöffnung in einem geringen Abstand von der Fläche des Vertellungselementes angeordnet. Um diesen Abstand zu realisieren ist eine Abstandshalteranordnung vorgesehen, die parallel zueinander verlaufende Rippen aufweist, die zwischen sich Vertiefungen bilden. One of the previously explained dispensing device similar dispensing device with one of the distribution of the active substance fluid in the rinsing liquid serving rib plate is also known (DE 199 12 217 A1, WO 99/66140 A). At this Construction, the reservoir has an enclosed by an annular edge Outlet opening, via which the active substance fluid in the rinsing liquid is deliverable. On the holder, a plate-like distribution element is provided, on the one hand, a loading area overflowed during rinsing of rinsing liquid and on the other hand has a terminal region in which a Aufstechspitze is arranged. The inside of the reservoir is above the Outlet opening with the interposition of a free-flowing active fluid preventing bump tip with lateral ribs continuous with the distribution element in connection. For this purpose, the edge of the outlet opening in a small Distance from the surface of the Vertellungselementes arranged. Around this distance To realize a spacer assembly is provided which is parallel having mutually extending ribs which form recesses between them.

Diese Vertiefungen reichen vom Anschlußbereich in den Beaufschlagungsbereich bis zum gegenüberliegenden Rand und dienen im Beaufschlagungsbereich der Verteilung des Wirkstofffluids in die Spülflüssigkeit.These depressions extend from the terminal area into the loading area to the opposite edge and serve in the loading area the distribution of the active substance fluid into the rinsing fluid.

Eine weitere derartige Abgabevorrichtung ist in der internationalen Veröffentlichung WO 01/44591 A1 beschrieben. Bei dieser Konstruktion weist das Verteilungselment an der Oberseite, auf der vom Beaufschlagungsbereich abgewandten Seite des Anschlusspunktes einen vom Längsrand des Verteilungselmentes unter dem Rand hindurch reichenden, oberseitig offenen Belüftungskanal auf.Another such dispenser is in the international publication WO 01/44591 A1. In this construction, the Verteilelmentment at the top, facing away from the loading area Side of the connection point one from the longitudinal edge of the Verteilungselmentes under the edge passing through, open top ventilation duct on.

In der Druckschrift GB 2 338-496 A ist eine Abgabevorrichtung beschrieben, welche durch ein zusätzliches Ventil belüftet wird. Für die Funktionsweise dieses Ventils werden verschiedene Varianten dargestellt, jedoch ist die Ventilöffnung separat von der Auslassöffnung angeordnet.Document GB 2 338-496 A describes a dispensing device which is ventilated by an additional valve. For the functioning of this Valve are shown in different variants, but is the valve opening arranged separately from the outlet opening.

Bei allen aus dem Stand der Technik bekannten Abgabevorrichtungen muß man Vorsorge dafür treffen, daß auf irgendeine Weise das aus dem Vorratsbehälter austretende Wirkstofffluid durch in den Vorratsbehälter einströmende Luft ersetzt werden kann. Regelmäßig verwirklicht werden im Stand der Technik Belüftungskanäle, die unter die Auslaßöffnung des Vorratsbehälters reichen. Dadurch ergibt sich ein dynamisches Zusammenwirken von viskosem Wirkstofffluid und Luft, durch das der Luftaustausch gewährleistet wird.In all known from the prior art dispensing devices must be Make sure that in any way that from the reservoir Exiting active fluid replaced by flowing into the reservoir air can be. In the prior art, ventilation ducts are regularly realized. which extend under the outlet opening of the reservoir. This results a dynamic interaction of viscous active fluid and air, through which the air exchange is ensured.

Der Lehre liegt das Problem zugrunde, die bekannte Abgabevorrichtung zur Abgabe von Wirkstofffluiden hinsichtlich der Steuerungsmöglichkeit für die Abgabe des Wirkstofffluids zu optimieren.The teaching is based on the problem, the known dispensing device for delivery of drug fluids in terms of control of delivery of the drug fluid to optimize.

Die zuvor aufgezeigte Problemstellung ist bei einer Abgabevorrichtung mit den Merkmalen des Oberbegriffs von Anspruch 1 durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst. Im Stand der Technik ist der Belüftungskanal am inneren Ende randseitig offen. Der unter der Auslaßöffnung des Vorratsbehälters befindliche Anschlußbereich öffnet sich also lateral einerseits in Richtung des Beaufschlagungsbereiches, andererseits zum Belüftungskanal. Damit ist das klassische, dynamische Zusammenwirken von viskosem Wirkstofffluid und Luft zum Zwecke des Wirkstofffluid/Luft-Austausches realisiert.The problem identified above is in a dispenser with the Features of the preamble of claim 1 by the features of the characterizing Part of claim 1 solved. In the prior art is the ventilation duct at the inner end open at the edge. The under the outlet of the Reservoir located connection area thus opens laterally on the one hand in Direction of the Beaufschlagungsbereiches, on the other hand to the ventilation duct. This is the classic, dynamic interaction of viscous Active fluid and air realized for the purpose of drug fluid / air exchange.

Erfindungsgemäß ist erkannt worden, daß dieser seit Jahrzehnten bekannte, typische Luftaustausch über einen Belüftungskanal an der Oberseite des Verteilungselementes durch eine laterale Schließung des Belüftungskanals am inneren Ende optimiert werden kann. Dadurch wird die Luftzufuhr über den Belüftungskanal im entscheidenden Bereich nahe der Auslaßöffnung nach oben umgelenkt. Das entspricht der Aufstiegsrichtung der Luft in den Vorratsbehälter hinein. Dem Luftzutritt in den Vorratsbehälter wird der geringstrnögliche Widerstand entgegengesetzt. Gleichzeitig wird überraschenderweise verhindert, daß Wirkstofffluid in den Belüftungskanal eintritt, weil ein wie auch immer gearteter Kapillareffekt durch die Schließung des Endes des Belüftungskanals unterbunden, jedenfalls vermindert wird. Das Wirkstofffluid selbst dient der Abdichtung des Belüftungskanals, erlaubt aber den Zutritt von Luft über den Belüftungskanal. Das Wirkstofffluid wird selbst in entgegengesetzter Richtung zum Beaufschlagungsbereich hin abgegeben.According to the invention it has been recognized that this has been known for decades, typical Air exchange via a ventilation duct at the top of the distribution element by a lateral closure of the ventilation channel on the inner End can be optimized. As a result, the air supply through the ventilation duct deflected in the crucial area near the outlet opening upwards. This corresponds to the direction of advancement of the air into the storage container. the Admission of air into the storage container is counteracted by the least possible resistance. At the same time it is surprisingly prevented that drug fluid enters the ventilation duct because of whatever capillary effect prevented by the closing of the end of the ventilation duct, anyway is reduced. The drug fluid itself serves to seal the ventilation channel, but allows the access of air through the ventilation duct. The active substance fluid is even in the opposite direction to the loading area issued.

Die Schließung des lateralen Belüftungskanals am inneren Ende nach der Auslaßöffnung hat überdies zur Folge, daß die in den Anschlußbereich eintretende Spülflüssigkeit, die das Wirkstofffluid verdünnt und bestimmungsgemäß aus dem Anschlußbereich nach außen hin abführt, nicht, jedenfalls nicht mehr so stark wie bisher in den Belüftungskanal eintritt. Der Belüftungskanal bleibt der Belüftung vorbehalten.The closing of the lateral ventilation channel at the inner end after the outlet opening moreover has the consequence that the entering into the connection area Rinsing fluid that dilutes the drug fluid and intended from the Connecting area dissipates to the outside, not, at least not as strong as so far enters the ventilation duct. The ventilation channel remains the ventilation Reserved.

Die erfindungsgemäße Abgabevorrichtung bietet gemäß einer besonderen Ausführungsform die Möglichkeit, in den Vorratsbehältern 2 Kombinationen unterschiedlicher Wirkstofffluide einzusetzen, wobei gemäß einer bevorzugten Ausführungsform einer der Vorratsbehälter 2 eine Duftphase, insbesondere wie zuvor definiert, enthält.The dispensing device according to the invention offers according to a particular embodiment the possibility in the storage containers 2 combinations of different Insert drug fluids, according to a preferred embodiment one of the reservoir 2 a fragrance phase, in particular as before defined, contains.

Beispielsweise für einzusetzende Wirkstofffluid-Kombinationen sind parfümierte Duftstoffphasen kombiniert mit Chlorbleiche (miteinander zusammen nicht lagerstabil), parfümierte Duftphase mit hochkonzentrierter Tensidphase (Schaumbooster), Duftphase mit kalklösender, saurer Wirkstoffphase, Duftphase mit antibakterieller Wirkstoffphase, unterschiedliche Säure-Systeme, Duftphase kombiniert mit enzymhaltiger Wirkstoffphase, parfümierte Säurephase kombiniert mit wasserfärbender Phase, Duftphase mit geruchsabsorbierender Phase, parfümierte Säurephase mit Aktivsauerstoff, parfümierte Säurephase mit Wirkstoffphase, mit Polyacrylat verdickt etc. For example, for drug-fluid combinations to be used are perfumed Fragrance phases combined with chlorine bleach (together not storage stable), perfumed fragrance phase with highly concentrated surfactant phase (foam booster), Fragrance phase with lime-dissolving, acidic phase of active substance, fragrance phase with antibacterial Active ingredient phase, different acid systems, combined fragrance phase with enzyme-containing active substance phase, perfumed acid phase combined with water-coloring phase, fragrance phase with odor-absorbing phase, perfumed Acid phase with active oxygen, perfumed acid phase with active substance phase, thickened with polyacrylate etc.

Von besonderem Interesse sind dabei zähflüssige bis gelartige Wirkstofffluide mit Viskositäten im Bereich einiger tausend mPas, insbesondere von 2000 bis 5000 mPas, vorzugsweise 2500 bis 3500 mPas (gemessen mit Rotovisko LVT, Spindel 2, 6 U/min, 20°C).Of particular interest are viscous to gel-like drug fluids with Viscosities in the range of a few thousand mPas, in particular from 2000 to 5000 mPas, preferably 2500 to 3500 mPas (measured with Rotovisko LVT, spindle 2, 6 rpm, 20 ° C).

Fig. 1 zeigt, daß der Vorratsbehälter 2 einen auslaßseitigen Rand 3 und eine Auslaßöffnung 4 aufweist, über die das Wirkstofffluid in die Spülflüssigkeit abgebbar ist. Das dargestellte und insoweit bevorzugte, jedoch nicht zwingende Ausführungsbeispiel zeigt weiter, daß hier die Auslaßöffnung 4 in einem den Rand 3 bildenden Deckel 5 angeordnet ist. Im Deckel-5-wiederum ist die Auslaßöffnung 4 von einem gegenüber dem Rand 3 am Deckel 5 nach innen versetzten Auslaßrand 3' gebildet.Fig. 1 shows that the reservoir 2 has an outlet side edge 3 and a Outlet opening 4, via which the active substance fluid can be dispensed into the rinsing liquid is. The illustrated and so far preferred, but not mandatory Embodiment further shows that here the outlet opening 4 in a the Edge 3 forming cover 5 is arranged. In the lid-5-turn is the outlet opening 4 offset from one opposite the edge 3 on the lid 5 inwardly Outlet edge 3 'is formed.

Im dargestellten Ausführungsbeispiel ist ein auswechselbarer Vorratsbehälter 2 vorgesehen, dessen Auslaßöffnung 4 zunächst mit einem Stopfen 5' fest verschlossen ist. Durch das Einsetzen des Vorratsbehälters 2 in den Halter 1 wird der Stopfen 5', wie in Fig. 1 erkennbar, nach oben aus der Auslaßöffnung 4 in das Innere des Vorratsbehälters 2 gestoßen, so daß die Auslaßöffnung 4 dann geöffnet ist. Die Verwendung eines Deckels 5 mit dem darin über eine Sollbruchstelle zunächst verschließend fixierten Stopfen 5' ist herstellungsmäßig zweckmäßig. Man will den Vorratsbehälter 2 ja mit einer großen Öffnung schnell befüllen können, anschließend soll die Auslaßöffnung 4 aber nach ganz anderen Gesichtspunkten angeordnet und gestaltet sein. Außerdem wird der Stopfen 5' als verlorenes Element verwendet, um ein einfaches Aufstecken des Vorratsbehälters 2 mit nach unten gerichteter Auslaßöffnung 4 zu ermöglichen.In the illustrated embodiment, a replaceable reservoir is the second provided, the outlet 4 initially closed with a plug 5 'tight is. By inserting the reservoir 2 in the holder 1 is the stopper 5 ', as seen in Fig. 1, upwardly from the outlet opening 4 in the interior of the reservoir 2 is pushed, so that the outlet port 4 then is open. The use of a lid 5 with the therein a predetermined breaking point initially sealingly fixed plug 5 'is suitable for production. One wants to fill the reservoir 2 with a large opening quickly can, then the outlet 4 but after completely different points of view be arranged and designed. In addition, the plug 5 'as lost element used to simply plug in the reservoir 2 with downwardly directed outlet opening 4 to allow.

Am Halter 1 ist ein plattenartiges Verteilungselement 6 vorgesehen, daß einerseits einen beim Spülvorgang von Spülflüssigkeit überströmten Beaufschlagungsbereich 7 und andererseits einen Anschlußbereich 8, in dem ein Anschlußpunkt 9 für die Auslaßöffnung 4 des Vorratsbehälters 2 angeordnet ist, aufweist. Das kann man in Fig. 2 mit Fig. 1 zusammen gut nachvollziehen.On the holder 1, a plate-like distribution element 6 is provided, on the one hand an overflow during the rinsing liquid flushing area 7 and on the other hand, a connection area 8, in which a connection point 9 is arranged for the outlet opening 4 of the reservoir 2, has. This can be understood well in Fig. 2 with Fig. 1 together.

Das Innere des Vorratsbehälters 2 steht über die Auslaßöffnung 4, und zwar im dargestellten Ausführungsbeispiel unter Zwischenanordnung einer ein freies Fließen des Wirkstofffluids verhindernden, im dargestellten und bevorzugen Ausführungsbeispiel am Anschlußpunkt 9 eine Aufstoßspitze aufweisenden Anordnung dauernd mit dem Verteilungselement 6 in Verbindung. Um dies zu realisieren ist der Rand 3 - bei am Halter 1 angebrachtem Vorratsbehälter 2 - in einem geringen Abstand von der Fläche des Verteilungselementes 6 angeordnet.The interior of the reservoir 2 is above the outlet opening 4, in the illustrated embodiment with interposition of a free Flow of the drug fluid preventing, in the illustrated and preferred embodiment at the connection point 9 a Aufstoßspitze having arrangement permanently connected to the distribution element 6 in connection. To realize this is the edge 3 - attached to the holder 1 reservoir 2 - in one small distance from the surface of the distribution element 6 is arranged.

Durch die zuvor erläuterte Anordnung ist der Vorratsbehälter 2 gegen den Eintritt von Spülflüssigkeit in sein Inneres geschützt und die Auslaßöffnung 4 des Vorratsbehälters 2 ist so angeordnet, daß i. w. nur Wirkstofffluid austritt und zum Ersatz des Wirkstoffftuids im Vorratsbehälter 2 Luft in das Innere des Vorratsbehälters 2 eintritt. Bei jedem Spülvorgang erfolgt die Abgabe einer Teilmenge des Wirkstofffluids aus dem Vorratsbehälter 2 in die Spülflüssigkeit. By the above-explained arrangement, the reservoir 2 is against the entrance protected by rinsing liquid in its interior and the outlet opening 4 of the reservoir 2 is arranged so that i. w. only active fluid exits and for replacement the Wirkstoffftuids in the reservoir 2 air into the interior of the reservoir 2 enters. For each rinse, the delivery of a subset of Active fluids from the reservoir 2 in the rinsing fluid.

Für die Anordnung und Anbringung des Vorratsbehälters 2 darf im übrigen auf den eingangs erläuterten Stand der Technik verwiesen werden. Im übrigen wird verwiesen auf ein nachveröffentlichtes Gebrauchsmuster DE 201 16 963 U, das auf die Anmelderin zurückgeht.For the arrangement and attachment of the reservoir 2 may otherwise be referred to the above-explained prior art. Otherwise, will refer to a postponed utility model DE 201 16 963 U, the to the applicant.

Die in Fig. 1 dargestellte Abgabevorrichtung zeigt im übrigen, daß bei dieser Ausführungsform der Halter 1 einen den Vorratsbehälter 2 aufnehmenden Träger 10 aufweist, wobei eine dem Beaufschlagungsbereich 7 zugewandte Vorderwand 11 am Übergang vom Anschlußbereich 8 zum Beaufschlagungsbereich 7 verläuft. Die Vorderwand 11 des Halters 1 dient der Abschirmung des Vorratsbehälters 2 gegen einen ungewollten Wassereintritt von dieser Seite. Die negativen Folgen eines ungewollten Wassereintritts in den Vorratsbehälter 2 sind bekannt, weiter oben erläutert und im übrigen Gegenstand umfangreicher Analysen im Stand der Technik.The dispensing device shown in Fig. 1 shows, moreover, that in this embodiment the holder 1 a reservoir 2 receiving the carrier 10th wherein a front wall 11 facing the loading area 7 at the transition from the terminal area 8 extends to the loading area 7. The front wall 11 of the holder 1 serves to shield the storage container 2 against an unwanted ingress of water from this side. The negative consequences an unwanted entry of water into the reservoir 2 are known, continue explained above and the rest of the subject of extensive analysis in the state of Technology.

Das in der Zeichnung dargestellte Ausführungsbeispiel einer Abgabevorrichtung zeigt nun, daß an der Oberseite des Verteilungselementes 6 auf der vorn Beaufschlagungsbereich 7 abgewandten Seite des Anschlußpunktes 9 ein vom Rand des Verteilungselementes 6 unter dem Rand 3 hindurch reichender, oberseitig offener Belüftungskanal 12 angeordnet ist. Der Belüftungskanal 12 dient der bereits oben erläuterten gezielten Luftzufuhr von außen in das innere des Vorratsbehälters 2, um die Ablauf-Charakteristik des Wirkstofffluids zu optimieren.The illustrated in the drawing embodiment of a dispenser shows now that at the top of the distribution element 6 on the front loading area 7 opposite side of the connection point 9 a from the edge of the distribution element 6 under the edge 3 reaching through, upper side open ventilation channel 12 is arranged. The ventilation duct 12 already serves explained above targeted air supply from the outside into the interior of the reservoir 2 to optimize the effluent characteristics of the drug fluid.

Das dargestellte Ausführungsbeispiel zeichnet sich nun, wie insbesondere der Ausschnitt in Fig. 1 gut zeigt, dadurch aus, daß der Belüftungskanal 12 am inneren Ende randseitig geschlossen ist. Mit anderen Worten ist der Belüftungskanal 12 offen einerseits in Richtung von der Auslaßöffnung 4 weg gerichtet, andererseits nach oben. Aufgrund der Lage des Randes 3 des Vorratsbehälters 2 gegenüber dem Verteilungselement 6 im Anschlußbereich 8 bedeutet dies, daß der Belüftungskanal 12 bezogen auf die Auslaßöffnung 4 eine nach oben gerichtete Luft-Austrittsöffnung bildet. Das hat die im allgemeinen Teil der Beschreibung erläuterten vorteilhaften Wirkungen hinsichtlich des Austausches Luft/Wirkstofffluid.The illustrated embodiment is now apparent, in particular the Section in Fig. 1 shows well, characterized in that the ventilation channel 12 at the inner End edge is closed. In other words, the ventilation duct 12 open on the one hand in the direction of the outlet opening 4 directed away, on the other up. Due to the position of the edge 3 of the reservoir 2 opposite the distribution element 6 in the connection area 8, this means that the Ventilation duct 12 based on the outlet opening 4 an upward Air outlet opening forms. This has explained in the general part of the description advantageous effects with respect to the exchange of air / active substance fluid.

Man kann den Belüftungskanal 12 im Verteilungselement 6 auf unterschiedliche Arten ausgestalten und diesen Belüftungskanal 12 auch unterschiedlich in der Form gestalten. Im Querschnitt kann sich dabei eine V-Form, eine U-Form oder auch eine Form eines mehrspurigen Kanals als zweckmäßig erweisen. Der Belüftungskanal 12 kann in das Material des Verteilungselementes 6 im Anschlußbereich 8 eingelassen sein. Das hat bereits den zuvor angesprochenen Vorteil der Umlenkung der Luft nach oben. Außerdem wird ein direktes laterales Einströmen von Spülflüssigkeit verhindert. Das dargestellte und bevorzugte Ausführungsbeispiel zeichnet sich weiter dadurch aus, daß der Belüftungskanal 12 am inneren Ende mittels eines von der Oberseite des Verteilungselementes 6 nach oben abragenden Kanalrandes 13 geschlossen ist. Gerade in der vergrößerten Darstellung von Fig. 1 erkennt man im Schnitt den Kanalrand 13, der den Belüftungskanal 12 innen abschließt. Der von der Fläche des Verteilungselementes 6 aufragende Kanalrand 13 verhindert besonders effektiv ein Eintreten des Gemisches aus Spülflüssigkeit und Wirkstofffluid in den Belüftungskanal 12. You can the ventilation channel 12 in the distribution element 6 to different Types ausgestalten and this ventilation duct 12 also different in the Shape shape. In cross section may be a V-shape, a U-shape or also prove a form of multi-lane channel to be useful. The ventilation duct 12 may be in the material of the distribution element 6 in the connection area 8 be embedded. This already has the previously mentioned advantage the deflection of the air upwards. There will also be a direct lateral inflow prevented by rinsing liquid. The illustrated and preferred embodiment is further characterized by the fact that the ventilation duct 12 am inner end by means of a from the top of the distribution element 6 after above projecting channel edge 13 is closed. Especially in the enlarged Representation of Fig. 1 can be seen in section the channel edge 13, the ventilation duct 12 in completes. The of the surface of the distribution element. 6 towering channel edge 13 prevents particularly effective entry of the mixture from rinsing liquid and active substance fluid in the ventilation channel 12.

Über die Querschnittsform des Belüftungskanals 12 ist zuvor schon einiges erläutert worden. Im dargestellten Ausführungsbeispiel ist der Belüftungskanal 12 einfach bodenseitig glatt ausgeführt. Allerdings ist, wie Fig. 2 zeigt, im dargestellten Ausführungsbeispiel vorgesehen, daß das geschlossene Ende des Belüftungskanals 12 V-förmig hier mit einer bestimmten Abrundung, oder U-förmig zulaufend ist. Damit schafft man einen breiten Belüftungskanal 12, der von außen her einen leichten Zustrom von Luft zuläßt, realisiert aber im Anschlußbereich 8 trotzdem einen definierten, geringen Luftdurchtrittsquerschnitt. Dieser Luftdurchtrittsquerschnitt ist zweckmäßigerweise auf die Viskosität und die sonstige Beschaffenheit des im Vorratsbehälter 2 befindlichen oder aufzunehmenden Wirkstofffluids abzustimmen, um die gewünschte Funktionsweise zu garantieren. Fig. 3 zeigt in der Perspektive die Lage und Breite der Belüftungskanäle 12.About the cross-sectional shape of the ventilation duct 12 is already explained a lot Service. In the illustrated embodiment, the ventilation channel 12 simply smooth on the bottom side. However, as shown in FIG. 2, in the illustrated Embodiment provided that the closed end of the ventilation duct 12 V-shaped here with a certain rounding, or tapered in a U-shape is. This creates a wide ventilation channel 12, the outside allows a slight influx of air, but realized in the connection area 8 nevertheless a defined, small air passage cross-section. This air passage cross section is suitably on the viscosity and the other condition of the container 2 located or to be received To match active fluids to guarantee the desired functionality. FIG. 3 shows the position and width of the ventilation channels 12 in perspective.

Im einzelnen ist im Ausführungsbeispiel realisiert, daß die das freie Fließen des Wirkstofffluids verhindernde Anordnung eine Abstandshalteranordnung mit Abstandshaltern 14 aufweist, die von der Oberseite des Verteilungselementes 6 geringfügig nach oben abragen und auf denen der Rand 3 des Vorratsbehälters 2 aufsteht. Der zuvor erläuterte Belüftungskanal 12 unterbricht nun diese Abstandshalteranordnung bzw. ist zwischen zwei Abstandshaltern 14 dieser Abstandshalteranordnung angeordnet.In particular, it is realized in the embodiment that the free flow of the Active fluid preventing arrangement a spacer assembly with spacers 14, which from the top of the distribution element 6 slightly protrude upwards and on which the edge 3 of the reservoir 2 gets up. The ventilation duct 12 explained above now interrupts this spacer arrangement or is between two spacers 14 of this spacer assembly arranged.

Für die Funktionsweise der erfindungsgemäßen Abgabevorrichtung hat es sich für bestimmte Viskositäten in Versuchen als zweckmäßig herausgestellt, daß die Abstandshalter 14 und der Kanalrand 13 des Belüftungskanals 12 von der Oberseite des Verteilungselementes 6 um das selbe Maß nach oben abragen. Dann liegt der Rand 3 des Vorratsbehälters 2 sowohl auf den Abstandshaltern 14 als auch auf dem Kanalrand 13 auf. Nur das innerste nach oben offene Ende des Belüftungskanals 12 stellt dann definiert den Luftzutrittsquerschnitt her.For the operation of the dispensing device according to the invention, it has For certain viscosities in experiments proved to be expedient that the Spacer 14 and the channel edge 13 of the ventilation channel 12 from the top of the distribution element 6 protrude upwards by the same amount. Then the edge 3 of the reservoir 2 is located both on the spacers 14 as also on the channel edge 13. Only the innermost open end of the Aeration duct 12 then defines the air inlet cross section defined.

Im einzelnen hat sich beim Einsatz von Wirkstofffluiden mit mittlerer Viskosität eine Bemaßung als zweckmäßig erwiesen, bei der vorgesehen ist, daß die Abstandshalter 14 von der Oberseite des Verteilungselementes 6 um etwa 0,7 mm nach oben abragen. Das dargestellte und bevorzugte Ausführungsbeispiel zeigt dabei gleichzeitig, daß der Kanalrand 13 von der Oberseite des Verteilungselementes 6 um etwa 0,7 mm nach oben abragt.In particular, has the use of active fluids with medium viscosity a dimension proved to be expedient, in which it is provided that the spacers 14 from the top of the distribution element 6 by about 0.7 mm protrude upwards. The illustrated and preferred embodiment shows at the same time that the channel edge 13 from the top of the distribution element 6 protrudes upwards by about 0.7 mm.

In weiteren Versuchen mit anderen Viskositäten hat es sich in einer Alternative auch als zweckmäßig erwiesen, den Kanatrand 13 um ein größeres Maß als die Abstandshalter 14 von der Oberseite des Verteilungselementes 6 nach oben abragen zu lassen, also beispielweise um 0,9 mm bei Abstandshaltern 14 von 0,7 mm. Damit ragt der Kanalrand 13 in den inneren Bereich des Deckels 5 innerhalb des Randes 3 hinein und stellt für das Gemisch aus Wirkstofffluid und Spülflüssigkeit innerhalb der Abstandshalteranordnung eine noch wirksamere Barriere dar.In other experiments with other viscosities, it has an alternative also proved to be useful, the Kanat 13 to a greater degree than the Abut spacer 14 from the top of the distribution element 6 upwards let, for example, by 0.9 mm for spacers 14 of 0.7 mm. Thus, the channel edge 13 projects into the inner region of the lid 5 within of the edge 3 and provides for the mixture of active fluid and rinsing liquid within the spacer assembly an even more effective barrier represents.

Weiter oben ist bereits darauf hingewiesen worden, daß der Vorratsbehälter 2 möglichst gegen den Eintritt von Spülflüssigkeit in sein Inneres geschützt sein sollte. Dazu ist im Ausführungsbeispiel weiter vorgesehen, daß im Anschlußbereich 8 auf der dem einen Längsrand zugewandten Seite des Anschlußpunktes 9, die Abstandshalter 14 auf dieser Seite umfassend, ein von der Oberseite des Verteilungselementes 6 nach oben geringfügig abragender Schutzrand 15 ausgebildet ist. Das dargestellte und bevorzugte Ausführungsbeispiel zeigt dabei, daß dieser Schutzrand 15 etwas weiter nach oben abragt als der Kanalrand 13 und die Abstandshalter 14, nämlich um hier 0,9 mm.It has already been pointed out above that the storage container 2 be protected as possible against the ingress of rinsing liquid into its interior should. For this purpose, it is further provided in the exemplary embodiment that in the connection area 8 on the one longitudinal edge facing side of the connection point 9, comprising the spacers 14 on this side, one from the top of the Distribution element 6 upwardly slightly projecting protective edge 15 is formed is. The illustrated and preferred embodiment shows, that this protective edge 15 projects slightly further upwards than the channel edge 13 and the spacers 14, namely 0.9 mm here.

Zuvor ist im einzelnen erläutert worden, daß es auf die innere Öffnung des Belüftungskanals 12 ankommt. Im einzelnen kann es sich dabei als zweckmäßig erweisen, jedoch natürlich abhängig-vom Viskositätsbereich, in dem das Wirkstofffluid liegt, daß der freie Querschnitt des Überdeckungsbereiches des Belüftungskanals 12 innerhalb des Randes 3 in Längsrichtung des Belüftungskanals 12 ein Maß von ca. 0,6 bis 1,5 mm, vorzugsweise von etwa 1,0 mm aufweist. Eine weitere Bestimmungsgröße für den Belüftungskanal 12 ist vorzugsweise eine maximale Breite von 1,0 bis 5,0 mm, vorzugsweise von etwa 2,5 mm. Das ergibt die weiter oben erläuterte gute Zutrittsmöglichkeit für Luft.Previously, it has been explained in detail that it is on the inner opening of the ventilation duct 12 arrives. In particular, it may prove to be expedient however, of course, depending on the viscosity range in which the Active substance fluid is that the free cross section of the overlap region of the Ventilation channel 12 within the edge 3 in the longitudinal direction of the ventilation duct 12 has a dimension of about 0.6 to 1.5 mm, preferably about 1.0 mm. Another determinant of the ventilation channel 12 is preferred a maximum width of 1.0 to 5.0 mm, preferably about 2.5 mm. This results in the above-mentioned good accessibility for air.

Um die Balance zwischen Luftzutritt und der Verhinderung eines Austritts von Wirkstofffluid und/oder Spülflüssigkeit in den Belüftungskanal 12 und damit einer Blockierung des Belüftungskanals 12 einzuhalten, empfiehlt es sich bei Wirkstofffluiden mittlerer Viskosität, daß der Belüftungskanal 12 an der inneren Peripherie des Randes 3 eine Breite von etwa 0,5 bis 2,5 mm, vorzugsweise von etwa 1,0 bis 1,5 mm aufweist. Aus den zuvor angegebenen bevorzugten Maßen ergibt sich ein freier Querschnitt am Ende des Belüftungskanals 12 für den Luftdurchtritt von 0,2 bis 2,2 mm2, vorzugsweise von 0,5 bis 1,0 mm2.In order to maintain the balance between admission of air and the prevention of leakage of active fluid and / or rinsing liquid into the ventilation channel 12 and thus blockage of the ventilation channel 12, it is recommended for medium viscosity active fluids that the ventilation channel 12 at the inner periphery of the edge 3 has a width from about 0.5 to 2.5 mm, preferably from about 1.0 to 1.5 mm. From the preferred dimensions given above results in a free cross-section at the end of the ventilation channel 12 for the passage of air from 0.2 to 2.2 mm 2 , preferably from 0.5 to 1.0 mm 2 .

Das dargestellte und insoweit bevorzugte Ausführungsbeispiel zeigt im übrigen, daß zwischen dem äußeren Rand des Anschlußpunktes 9 und dem Beaufschlagungsbereich 7 ein Streifen glatter Oberfläche des Anschlußbereichs 8 besteht.The illustrated and so far preferred embodiment shows, moreover, that between the outer edge of the connection point 9 and the Beaufschlagungsbereich 7 is a strip of smooth surface of the connection area 8.

Weiter oben ist bereits darauf hingewiesen worden, daß die beschriebene Abgabevorrichtung sich besonders zur Abgabe mehrerer, insbesondere zweier Wirkstofffluide aus mehreren, insbesondere zwei Vorratsbehältern 2 auf ein Verteilungselement 6 eignet. Fig. 2 zeigt insoweit ein Verteilungselement 6 für zwei Vorratsbehälter 2, die selbst nicht dargestellt sind. Bei dieser Ausführungsform einer Abgabevorrichtung ist vorgesehen, daß im Halter 1 mindestens zwei Vorratsbehälter 2 für jeweils ein Wirkstöfffluid vorgesehen sind. Beide Vorratsbehälter 2 sind in entsprechender Weise gegen den Eintritt von Spülflüssigkeit in ihr Inneres geschützt und beide Auslaßöffnungen 4 der Vorratsbehälter 2 sind so angeordnet, daß nur Wirkstofffluid austritt und möglichst nur Belüftungsluft wieder eintritt. Die Auslaßöffnungen 4 beider Vorratsbehälter 2 sind in der aus Fig. 1 zu entnehmenden Gebrauchsstellung bodenseitig angeordnet. Im dargestellten und bevorzugten Ausführungsbeispiel sind dabei die Vorratsbehälter 2 im Halter einzeln auswechselbar angebracht.It has already been pointed out above that the described dispensing device especially for the delivery of several, in particular two Active fluid from several, in particular two storage containers 2 on a distribution element 6 is suitable. Fig. 2 shows so far a distribution element 6 for two Reservoir 2, which are not shown themselves. In this embodiment a dispenser is provided that in the holder 1 at least two reservoir 2 are provided for each one Wirkstöfffluid. Both storage tanks 2 are in a similar manner against the entry of flushing liquid in it Protected inside and both outlet ports 4 of the reservoir 2 are so arranged that only active fluid exits and possibly only ventilation air again entry.

Fig. 2 macht deutlich, daß das plattenartige Verteilungselement 6 für beide Vorratsbehälter 2, bei Vorhandensein mehrerer Vorratsbehälter 2 für alle Vorratsbehälter 2, gemeinsam vorgesehen ist, daß das Verteilungselement 6 im Anschlußbereich 8 nebeneinander beabstandet die Anschlußpunkte 9 für die Auslaßöffnungen 4 der Vorratsbehälter 2 aufweist und daß jedem Anschlußpunkt 10 ein eigener Belüftungskanal 12 zugeordnet ist.Fig. 2 makes it clear that the plate-like distribution element 6 for both reservoir 2, in the presence of several storage containers 2 for all storage containers 2, is provided in common that the distribution element 6 in the connection area 8 side by side spaced the connection points 9 for the outlet openings 4 of the reservoir 2 and that each connection point 10 a own ventilation channel 12 is assigned.

Schließlich läßt eine Zusammenschau der Fig. 1 und 2 erkennen, daß das Verteilungselement 6 im Beaufschlagungsbereich 7 vom Rand des Anschlußbereichs 8 ausgehend und etwa bis zum gegenüberliegenden Längsrand reichend Vertiefungen 16 aufweist, die der Verteilung des Wirkstofffluids bzw. der Wirkstofffluide in die Spülflüssigkeit dienen. Im dargestellten Ausführungsbeispiel erstrecken sich die Vertiefungen 16 bis gerade unter den Rand der Vorderwand 11. Im dargestellten Ausführungsbeispiel und nach bevorzugter Lehre ist dabei vorgesehen, daß zwischen dem obersten Rand der Vertiefungen 16 im Beaufschlagungsbereich 7 und dem Rand der Vorderwand 11 des Trägers 10 nur ein geringer Spalt vorliegt, vorzugsweise ein Spalt von 0,1 bis 0,4 mm, insbesondere ein Spalt von etwa 0,2 bis 0,3 mm.Finally, a synopsis of Figs. 1 and 2 can be seen that the distribution element 6 in the loading area 7 from the edge of the connection area 8 starting and reaching approximately to the opposite longitudinal edge depressions 16, the distribution of the active substance fluid or the active substance fluids serve in the rinsing liquid. In the illustrated embodiment extend the depressions 16 to just below the edge of the front wall 11. In the illustrated Embodiment and preferred teaching is provided here, that between the uppermost edge of the recesses 16 in the Beaufschlagungsbereich 7 and the edge of the front wall 11 of the carrier 10 only a small Gap is present, preferably a gap of 0.1 to 0.4 mm, in particular a Gap of about 0.2 to 0.3 mm.

Fig. 1 macht die Lage der Vorderwand 11 des Halters 1 bezogen auf die Vertiefungen 16 im Beaufschlagungsbereich 7 des Verteilungselements 6 deutlich. Fig. 1 macht femer deutlich, daß im hier dargestellten Ausführungsbeispiel der Träger 10 nicht integraler Bestandteil des Halters 1 ist, sondern ein gesondertes Einsatzteil ist, das in den Halter 1 eingesetzt wird. Die Vorderwand 11 ist hier am Halter 1 ausgebildet. Ist der Träger 10 integraler Bestandteil des Halters 1, so ist die Vorderwand 11 am Halter 1 ausgebildet.Fig. 1 makes the position of the front wall 11 of the holder 1 with respect to the recesses 16 in the loading area 7 of the distribution element 6 clearly. FIG. 1 further makes it clear that in the embodiment shown here, the carrier 10 is not an integral part of the holder 1, but a separate Insert is used in the holder 1. The front wall 11 is here on Holder 1 is formed. If the carrier 10 is an integral part of the holder 1, then the front wall 11 is formed on the holder 1.

Das dargestellte Ausführungsbeispiel läßt in Fig. 1 im übrigen erkennen, daß die Oberseite des Verteilungselementes 6 im Anschlußbereich 8 in Höhe des tiefsten Punktes der Vertiefungen 16 im Beaufschlagungsbereich 7 verläuft. Das Wirkstofffluid kann so stimseitig in die Vertiefungen 16 eintreten. Gleichzeitig wird die Zutrittsmöglichkeit für Wasser unter den Rand der Vorderwand 11 so stark wie möglich beschränkt. Man erkennt in Fig. 1 im übrigen weiter, daß sich zwischen der Unterseite des Halters 1 und der Oberfläche des Verteilungselements 6 im Anschlußbereich 8 in den freien Bereichen ein beachtlicher vertikaler Abstand ergibt.The illustrated embodiment can be seen in Fig. 1 in the rest that the Top of the distribution element 6 in the connection area 8 at the level of the deepest Point of the recesses 16 extends in the loading area 7. The Active substance fluid can thus enter the depressions 16 in a stimulus-like manner. At the same time the access for water under the edge of the front wall 11 so strong as limited as possible. It can be seen in Fig. 1, moreover, that between the underside of the holder 1 and the surface of the distribution element 6 in the connection area 8 in the free areas a considerable vertical distance results.

Fig. 2 zeigt schließlich noch, daß wie bereits erläutert, die Oberseite des Verteilungselements 6 im Anschlußbereich 8 für das Wirkstofffluid glatt ist, im übrigen aber aus befestigungstechnischen, anschlußtechnischen und abdichtungstechnischen Gründen einzelne Erhöhungen aufweisen kann.Fig. 2 finally shows that, as already explained, the top of the distribution element 6 in the connection area 8 for the drug fluid is smooth, otherwise but from fastening technology, connection technology and sealing technology Reasons may have individual increases.

Schließlich darf nochmals auf die weiter oben im speziellen Teil der Beschreibung bereits angesprochenen bevorzugten Viskositätsbereiche für das Wirkstofffluid hingewiesen werden. Diese sind besonders zweckmäßig zu realisieren.Finally, again on the above in the special part of the description already mentioned preferred viscosity ranges for the Be pointed drug fluid. These are particularly useful to implement.

Fig. 2 und 3 machen im übrigen deutlich, daß hier ein von der Oberseite des Verteilungselementes 6 geringfügig nach oben abragender Mittelrand 17 realisiert ist, der im dargestellten Ausführungsbeispiel dafür sorgt, daß die dort möglicherweise nicht miteinander kompatiblen Wirkstofffluide der beiden Vorratsbehälter 2 sich erst im Beaufschlagungsbereich 7 unter Hinzutreten von Spülflüssigkeit miteinander vermischen können. Im übrigen gibt es dafür eine Vielzahl von weiteren Varianten für miteinander kompatible und miteinander nicht kompatible Wirkstofffluide, wozu ebenfalls nochmals auf die nicht vorveröffentlichte DE 201 16 963 U hingewiesen werden darf.In addition, Figs. 2 and 3 make it clear that here is one from the top of the distribution element 6 slightly upwardly projecting center edge 17 realized is that in the illustrated embodiment ensures that there possibly incompatible drug fluids of the two reservoirs 2 only in the loading area 7 with the addition of rinsing liquid with each other can mix.
