Description

Die Erfindung betrifft eine Austragvorrichtung nach dem Oberbegriff des Patentanspruches 1. Sie ist für Medien beliebiger Art bzw. für fließfähige Medien vorgesehen, wobei insbesondere Mittel zur manuellen oder ähnlichen Austrag-Betätigung vorgesehen sind.The invention relates to a discharge device according to the preamble of claim 1. It is provided for media of any kind or for flowable media, in particular means for manual or similar discharge actuation being provided.

Die Austragvorrichtung weist zweckmäßig eine Erfassungseinrichtung zur Erfassung relevanter Daten, zum Beispiel zum Speichern und Anzeigen einer ersten Benutzung, der Anzahl der durchgeführten Austragzyklen o.dgl. auf. Zu diesem Zweck wird die Erfassungeinrichtung über ein zum Beispiel manuell oder ähnlich zu beeinflussendes Betätigungsglied gesteuert.The discharge device expediently has a detection device for recording relevant data, for example for storing and displaying a first use, the number of discharge cycles carried out or the like. on. For this purpose, the detection device is controlled via an actuator that can be influenced, for example, manually or in a similar manner.

Ist die Erfassung im wesentlichen streng und unbeeinflußbar an die Austrag-Betätigung gebunden, so ist zum Beispiel bei kosmetischen oder pharmazeutischen Anwendungen eine Erfassung nur der Tatsache der Anwendung unabhängig von der Anzahl der jeweils durchgeführten Austragzyklen nicht möglich.If the detection is essentially strictly and uninfluenced by the discharge operation, it is, for example, in cosmetic or pharmaceutical applications it is not possible to record only the fact of the application regardless of the number of discharge cycles carried out.

Die US-A-4 565 302 zeigt eine Austragvorrichtung mit einer Erfassungseinrichtung, die jeweils durch Betätigen der Austrag-Betätigungseinrichtung zwangsläufig weitergeschaltet wird. Ein zusätzlicher Ring kann zwar mit der Erfassungseinrichtung gekuppelt, jedoch weder im ausgekuppelten noch im eingekuppelten Zustand unabhängig von der Austrag-Betätigungseinrichtung betätigt werden.US-A-4 565 302 shows a discharge device with a detection device which is inevitably switched on by actuating the discharge actuation device. An additional ring can be coupled to the detection device, but can be actuated independently of the discharge actuating device neither in the disengaged nor in the coupled state.

Die DE-B-1 227 198 zeigt ein Futteral für eine Austragvorrichtung; eine Erfassungseinrichtung für Daten wird jedoch nicht erwähnt.DE-B-1 227 198 shows a case for a discharge device; a data acquisition device is not mentioned, however.

Der Erfindung liegt die Aufgabe zugrunde, eine Austragvorrichtung bzw. für eine solche Austragvorrichtung eine Erfassungseinrichtung zu schaffen, bei welcher Nachteile bekannter Ausbildungen bzw. der beschriebenen Art vermieden sind und die insbesondere eine willkürliche Erfassung ermöglicht.The invention has for its object to provide a discharge device or for such a discharge device a detection device in which disadvantages of known designs or of the type described are avoided and which in particular enables arbitrary detection.

Zur Lösung sind die Merkmale des Patentanspruches 1 geeignet. Es ist ein Betätigungsglied für die Erfassungseinrichtung vorgesehen, das unabhängig von der Austrag-Betätigung manuell oder ähnlich betätigt werden kann und daher eine Datenspeicherung unabhängig von der Austrag-Betätigung zuläßt. Zum Beispiel kann die Anzahl der Anwendungen mit oder ohne direkte Anzeige erfaßt werden. Ferner kann der nächstfolgende Anwendungszeitpunkt unabhängig davon angezeigt werden, wieviel Austrag-Betätigungen bei der letzten Anwendung durchgeführt worden sind.The features of claim 1 are suitable for solving. An actuating element is provided for the detection device, which can be actuated manually or similarly independently of the discharge actuation and therefore permits data storage independently of the discharge actuation. For example, the number of applications can be recorded with or without a direct display. Furthermore, the next application time can be displayed regardless of how many discharge operations have been carried out in the last application.

Das Betätigungsglied kann wenigstens teilweise axial und/oder radial von der Austragvorrichtung abhebbar, z.B. abklappbar oder nach Art eines Betätigungsschlüssels vollständig von der Austragvorrichtung trennbar sein. In beiden Fällen kann es so ausgebildet sein, daß es in eingesetztem Zustand nach Art einer Sperre eine Betätigung der Austragvorrichtung unmöglich macht.The actuating member can be at least partially axially and / or radially liftable from the discharge device, for example foldable or completely separable from the discharge device in the manner of an actuation key. In both cases, it can be designed such that, in the inserted state, it makes it impossible to actuate the discharge device in the manner of a lock.

Soll ein gewisser Zwang zur Betätigung der Erfassungseinrichtung am Ende einer Anwendung des Mediums vorgegeben sein, so kann das Betätigungsglied so ausgebildet sein, daß ohne seine Überführung in eine Betätigungsstellung zumindest eine Erschwerung der Verwahrung der Austragvorrichtung gegeben ist. Dies kann zum Beispiel dadurch erreicht werden, daß das Betätigungsglied als Verschluß, Schutzkappe o.dgl. wenigstens für einen Teil der Austragvorrichtung nämlich für mindestens einen der Bauteile, ausgebildet ist, die durch die Austrag-Betätigung, die Erfassungseinrichtung und eine Austragöffnung gebildet sind. Beim Aufsetzen dieses Verschlusses wird dadurch automatisch die Erfassungseinrichtung betätigt.If there is to be a certain pressure to actuate the detection device at the end of an application of the medium, the actuating member can be designed in such a way that, without being transferred to an actuating position, there is at least some difficulty in keeping the discharge device safe. This can be achieved, for example, that the actuator or the like as a closure, protective cap. at least for part of the discharge device namely for at least one of the components, which are formed by the discharge actuation, the detection device and a discharge opening. When this closure is put on, the detection device is automatically actuated.

Insbesondere wenn die Stellbewegung des mit dem Betätigungsglied zu schaltenden Gliedes der Austragvorrichtung eine zum Betätigungsglied etwa koaxiale Drehbewegung ist, ist die Anordnung zweckmäßig so vorgesehen, daß das Betätigungsglied gegen Verdrehen gesichert ist. Das abhebbare Betätigungsglied wird bei der Betätigungsbewegung zuerst in Steckeingriff mit einer Verdrehsicherung und dann in Steckeingriff mit einer Bewegungssteuerung für das bewegbare Glied gebracht. Dieses Glied kann unmittelbar ein Erfassungsglied sein, das entweder eine Markierung, wie ein Anzeigefenster für die Bewegung entlang einer Skala und/oder eine solche Skala für die Bewegung entlang einer Markierung o.dgl. aufweist. Die Betätigungsglieder, Erfassungseinrichtungen, Sicherungsführungen, Stellglieder, Anzeigeeinrichtungen, Schaltrastungen, Grundkörper u.dgl. gemäß den Unteransprüchen können jeweils gesondert vorgesehen oder die entsprechenden Merkmale in einer einzigen Anordnung zusammengefaßt sein. Insofern kann die Austragvorrichtung zwei oder mehr zwangsläufig steuerverbundene und/oder unabhängig voneinander betätigbare Erfassungseinrichtungen aufweisen.In particular, if the actuating movement of the member of the discharge device to be switched with the actuating member is a rotational movement approximately coaxial with the actuating member, the arrangement is expediently provided such that the actuating member is secured against rotation. The actuating element which can be lifted off is brought into engagement with an anti-rotation device during the actuation movement and then into engagement with a movement control for the movable member. This element can be a detection element that has either a marking, such as a display window for moving along a scale and / or such a scale for moving along a marking or the like. having. The actuators, detection devices, safety guides, actuators, display devices, switching detents, base body and the like. according to the subclaims, each can be provided separately or the corresponding features can be combined in a single arrangement. In this respect, the discharge device can have two or more detection devices which are inevitably tax-linked and / or can be actuated independently of one another.

Die erfindungsgemäße Erfassungseinrichtung ist für Austragvorrichtungen geeignet, die mit mindestens einer Pumpe, z.B. einer Schubkolbenpumpe, mit einem quetschbaren Speichergefäß, mit einer Pipette, mit einem Tropfspender oder ähnlichem zu betätigen sind. Sie ist auch für solche Austragvorrichtungen geeignet, die mindestens zwei gesonderte, gemeinsam und/oder unabhängig voneinander betätigbare Einzel-Austragvorrichtungen aufweisen, welche ggf. aus gesonderten Speichern fördern.The detection device according to the invention is suitable for discharge devices which can be operated with at least one pump, for example a push piston pump, with a squeezable storage vessel, with a pipette, with a drip dispenser or the like. It is also suitable for discharge devices that have at least two separate, have jointly and / or independently operable individual discharge devices which, if necessary, convey from separate memories.

Unabhängig von der beschriebenen Ausbildung kann die erfindungsgemäße Aufgabe auch dadurch gelöst werden, daß mindestens eine Erfassungseinrichtung im wesentlichen unabhängig von einem Austragförderer, wie einer Austragpumpe, montierbar bzw. durch eine von einem solchen Austragförderer gesonderte Montage- oder Baugruppe gebildet ist, die zum Beispiel unmittelbar an einem mit dem Austragförderer zu versehenden Speichergefäß oder über einen gesonderten Flansch mit einem Befestigungsglied an dem Speichergefäß zu befestigen ist, mit welchem auch der Austragförderer befestigt wird. Bei einer sehr einfachen Ausbildung wird ein Grundkörper der Erfassungeinrichtung mit einer federnden Rast- bzw. Schnappverbindung oder einer klemmenden Steckverbindung montiert. Die Erfassungseinrichtung kann dadurch wahlweise an Speichergefäßen angebracht werden, ohne daß dadurch die Ausgestaltung des Austragförderers beeinflußt wäre.Irrespective of the design described, the object according to the invention can also be achieved in that at least one detection device can be mounted essentially independently of a discharge conveyor, such as a discharge pump, or is formed by an assembly or assembly which is separate from such a discharge conveyor and which, for example, is direct on a storage vessel to be provided with the discharge conveyor or via a separate flange with a fastening element on the storage vessel, with which the discharge conveyor is also fastened. In a very simple design, a base body of the detection device is mounted with a resilient snap or snap connection or a clamping plug connection. As a result, the detection device can optionally be attached to storage vessels without the design of the discharge conveyor being influenced thereby.

Zur Lösung der Aufgabe wird des weiteren auch ein Futteral für die Austragvorrichtung vorgeschlagen, das zweckmäßig für die im wesentlichen vollständig verkapselte Aufnahme sowohl eines Speichergefäßes als auch des an diesem angebrachten Austragförderers ausgebildet ist. Soll eine Erfassungseinrichtung vorgesehen werden, so kann diese baulich unmittelbar mit dem Futteral vereint werden, ohne daß die Austrageinheit aus Speicher und Förderer in irgendeiner Weise verändert werden muß. Der Speicher besteht zweckmäßig aus Glas.To solve the problem, a case for the discharge device is also proposed, which is expediently designed for the substantially completely encapsulated reception of both a storage vessel and the discharge conveyor attached to it. If a detection device is to be provided, this can be structurally combined directly with the case without the discharge unit comprising the storage device and conveyor having to be changed in any way. The memory suitably consists of glass.

Durch die erfindungsgemäße Ausbildung kann jede Austragvorrichtung wahlweise an den jeweiligen Anwendungsfall zumindest insofern angepaßt werden, als sie mit einer in beliebiger Weise arbeitenden Erfassungseinrichtung versehen werden kann. Dadurch kann die Austragvorrichtung zum Beispiel mit einer solchen Erfassungseinrichtung zusammengesetzt werden, die dem jeweiligen ärztlich verschriebenen, individuellen Anwendungsmodus einer Medizin entspricht.With the design according to the invention, each discharge device can optionally be adapted to the respective application, at least insofar as it can be used in any one Wise working detection device can be provided. As a result, the discharge device can be assembled, for example, with such a detection device that corresponds to the respective medically prescribed, individual mode of use of a medicine.

Die Austragvorrichtung 1 weist eine als in sich geschlossene Montagebaugruppe ausgebildete Austrageinheit 2 mit einem Austragförderer 3 und einem Speichergefäß 4 auf, die durch eine Austrag-Betätigungseinrichtung 5 manuell zu betätigen sind. Hierbei wird die Kolbeneinheit 7 einer zum größten Teil in das Speichergefäß 4 eingreifenden Pumpe 6 betätigt, deren Pumpenkammer einen ventilgesteuerten Einlaß 8 und einen ventilgesteuerten Auslaß 9 aufweist. Zur Betätigung ist ein Kolben- bzw. Betätigungsstößel 10 vorgesehen, der mit einer Förderhandhabe 11 in Form einer ihn umgebenden Druckfläche verbunden und über eine Steckverbindung an dem Kolbenstößel der Kolbeneinheit 7 angeordnet ist. Der Betätigungsstößel 10 ist von einem an den Auslaß 9 angeschlossenen Auslaßkanal durchsetzt, von einem einteilig mit ihm ausgebildeten und etwa in der Pumpenachse liegenden Austragstutzen 12 umgeben und weist im Bereich seiner Endfläche die ins Freie führende Austragdüse oder Austragöffnung 13 der Austrageinheit 2 auf. Das Zylindergehäuse bildet mit einem Zylinderdeckel einen Grundkörper 14, mit welchem der Austragförderer 3 durch ein Befestigungsglied 15, zum Beispiel einen kappenförmigen Gefäßflansch 16 umgreifenden Krimpring an dem Gefäßhals 17 befestigt ist. Zwischen diesem Gefäßflansch 16 und dem Gefäßbauch 18 bildet der Gefäßhals 17 am Außenumfang eine Ringnut, die an einer Flanke von dem Befestigungsglied 15 begrenzt sein kann. Der aus dem Speichergefäß 4 vorstehende Teil des Grundkörpers und das Befestigungsglied 15 werden von einer Kappe 19 übergriffen, welche mit ihrer Stirnseite die Förderhandhabe 11 bildet.The discharge device 1 has a discharge unit 2 designed as a self-contained assembly assembly with a discharge conveyor 3 and a storage vessel 4, which can be operated manually by a discharge actuation device 5. Here, the piston unit 7 of a pump 6 engaging for the most part in the storage vessel 4 is actuated, the pump chamber of which has a valve-controlled inlet 8 and a valve-controlled outlet 9. For actuation, a piston or actuating tappet 10 is provided, which is connected to a conveyor handle 11 in the form of a pressure surface surrounding it and is arranged on the plunger tappet of the piston unit 7 via a plug connection. The actuating plunger 10 is connected to the outlet 9 by a Extends through the outlet channel, surrounded by a discharge nozzle 12 formed in one piece with it and lying approximately in the pump axis and has in the region of its end face the discharge nozzle or discharge opening 13 of the discharge unit 2 leading to the outside. The cylinder housing forms a base body 14 with a cylinder cover, with which the discharge conveyor 3 is fastened to the vessel neck 17 by means of a fastening member 15, for example a crimp ring encompassing a cap-shaped vessel flange 16. Between this vessel flange 16 and the vessel belly 18, the vessel neck 17 forms an annular groove on the outer circumference, which can be delimited on one side by the fastening member 15. The part of the base body protruding from the storage vessel 4 and the fastening member 15 are overlapped by a cap 19 which forms the conveying handle 11 with its end face.

Zur Zählung der Häufigkeit des Öffnens bzw. Freilegens der mit einer Schutzkappe gesicherten Austrag-Betätigung 5 ist eine Erfassungseinrichtung 20 vorgesehen, die eine von der Austrageinheit 2 unabhängig zu montierende Baugruppe bildet, welche vor oder nach der Austrageinheit 2 am Speichergefäß 4 befestigt werden und gegenüber der Austrageinheit 2 im wesentlichen berührungsfrei sein kann. Die Erfassungseinrichtung 20 weist einen hülsenförmigen Grundkörper 21 auf, welcher zentriert am Außenumfang des Speichergefäßes 4 anliegt und teilweise auch den Grundkörper 14, das Befestigungsglied 15 und/oder die Kappe 19 umgibt. An seinem Außenumfang trägt der Grundkörper 21 bewegbar, insbesondere etwa um die Pumpenachse drehbar, ein hülsen- bzw. ringförmiges Erfassungsglied 22, das mit dem durch die Schutzkappe gebildeten Betätigungsglied 23 dann jedesmal einen Schritt weitergeschaltet wird, wenn das Betätigungsglied 23 zur Abdeckung der Austrag-Betätigung 5, des Austragstutzens 12, der Austragöffnung 13, des Erfassungsgliedes 22 und/oder weiterer Bauteile aufgesetzt wird. Der Grundkörper 21 ist mit einer Schnappverbindung 24 durch axiales Aufstecken am Gefäßhals 17 befestigt und weist hierzu am Innenumfang einen federnd aufweitbaren Ringwulst 25 auf, der in die Ringnut des Gefäßhalses 17 im wesentlichen axialspielfrei und vorgespannt eingreift. Die Kappe 19 ist mit dem Betätigungsstößel 10 nach der Montage des Grundkörpers 21 an dem Kolbenstößel durch Aufstecken zu befestigen, so daß der Ringwulst 25 bei der Montage über das Befestigungsglied 15 hinweggleiten kann.To count the frequency of opening or exposing the discharge actuation 5 secured with a protective cap, a detection device 20 is provided which forms an assembly to be mounted independently of the discharge unit 2, which are attached to the storage vessel 4 before and after the discharge unit 2 and opposite the discharge unit 2 can be essentially non-contact. The detection device 20 has a sleeve-shaped base body 21, which rests centered on the outer circumference of the storage vessel 4 and partially also surrounds the base body 14, the fastening member 15 and / or the cap 19. On its outer circumference, the base body 21 carries a sleeve-shaped or ring-shaped detection element 22, which can be moved, in particular rotates approximately about the pump axis, and which is switched one step further with the actuating element 23 formed by the protective cap whenever the actuating element 23 covers the discharge. Actuation 5, the discharge nozzle 12, the discharge opening 13, the detection member 22 and / or other components is placed. Of the Base body 21 is fastened with a snap connection 24 by axial plugging onto the vessel neck 17 and for this purpose has a resiliently expandable annular bead 25 on the inner circumference, which engages in the annular groove of the vessel neck 17 essentially without axial play and pretensioned. The cap 19 is to be fastened with the actuating tappet 10 after the assembly of the base body 21 on the piston tappet by plugging on, so that the annular bead 25 can slide over the fastening member 15 during assembly.

Das Erfassungsglied 22 ist mit einer Schnappverbindung 26 axial gesichert am Grundkörper 21 angeordnet und weist hierzu am Innenumfang einen Ringwulst 27 auf, der in eine Ringnut am Außenumfang eines hülsenförmigen Mantelabschnittes 28 eingreift, welcher den an den Ringwulst 25 anschließenden Endabschnitt des Grundkörpers 21 bildet und die Kappe 19 am Außenumfang umgibt.The detection member 22 is arranged with a snap connection 26 axially secured to the base body 21 and for this purpose has an annular bead 27 on the inner circumference, which engages in an annular groove on the outer periphery of a sleeve-shaped jacket section 28, which forms the end portion of the base body 21 adjoining the annular bead 25 and the Cap 19 surrounds on the outer circumference.

Das Betätigungsglied 23 kann eckige oder im wesentlichen kreisrunde Basisquerschnitte haben. Zweckmäßig wird es nach Beginn des selbstzentrierenden Aufsteckens auf den Grundkörper 21 durch eine dann in Eingriff gelangende Sicherungsführung 29 gegen Verdrehen um seine Mittelachse gesichert, wobei das Betätigungsglied 23 zweckmäßig nur in Eingriff mit der an der Austrageinheit 2 angeordneten Baugruppe der Erfassungseinrichtung 20 gelangt und gegenüber der Austrageinheit 2 im wesentlichen berührungsfrei bleibt.The actuator 23 can have angular or substantially circular base cross sections. After the self-centering attachment to the base body 21, it is expediently secured against rotation about its central axis by a locking guide 29 which then comes into engagement, the actuating member 23 expediently only engaging with the assembly of the detection device 20 arranged on the discharge unit 2 and with respect to the Discharge unit 2 remains essentially contactless.

Nachdem die Sicherungsführung 29 in Eingriff gelangt ist, kommt das Betätigungsglied 23 über einen Stelltrieb 30 so in Eingriff mit dem Erfassungsglied 23, daß dieses um einen von mehreren Schaltschritten weitergedreht wird. Die Sicherungsführung 29 weist am Innenumfang des Betätigungsgliedes 23 und mit geringem Abstand von dessen Kappenöffnung über den Umfang verteilte, durch Axialstege gebildete Sicherungsnocken 31 auf, die an ihren Enden schräge Einlaufflächen haben. Entsprechende Sicherungsnocken 31 sind auch am Außenumfang des Grundkörpers 21 etwa im Axialbereich des Ringwulstes 25 vorgesehen. Zwischen seitlich benachbarten Sicherungsnocken 31 sind etwa axiale Sicherungsnuten 32 gebildet, die zu ihren Eingriffsenden trichterförmig erweitert sind. Beim Aufstecken des Betätigungsgliedes 23 gelangen die Sicherungsnocken 31 jeweils des einen Bauteiles in die Sicherungsnuten 32 des jeweils anderen Bauteiles, so daß der Grundkörper 21 und das Betätigungsglied 23 gegeneinander verdrehgesichert sind.After the safety guide 29 has come into engagement, the actuating member 23 comes into engagement with the detection member 23 via an actuating drive 30 such that it is rotated further by one of several switching steps. The safety guide 29 has on the inner circumference of the actuating member 23 and at a short distance from its cap opening distributed over the circumference, formed by axial webs Safety cams 31, which have inclined inlet surfaces at their ends. Corresponding securing cams 31 are also provided on the outer circumference of the base body 21 approximately in the axial region of the annular bead 25. Between laterally adjacent securing cams 31, approximately axial securing grooves 32 are formed, which are widened in a funnel shape at their engagement ends. When the actuator 23 is plugged in, the locking cams 31 of one component enter the locking grooves 32 of the other component, so that the base body 21 and the actuator 23 are secured against rotation.

Der Stelltrieb 30 weist in größerer Entfernung von der Kappenöffnung ebenfalls am Innenumfang des Mantels des Betätigungsgliedes 32 gleichmäßig über den Umfang verteilte Stellnocken 33 in Form von etwa axialen Stegvorsprüngen auf. Entsprechende Gegennocken 34 sind am Außenumfang und nur an einem Endabschnitt des Erfassungsgliedes 22 vorgesehen. Die Stellnocken 33 und die Gegennocken 34 weisen komplementär schräge Endflächen auf, mit welchen sie bei verdrehgesichertem Betätigungsglied 23 während dessen weiterer Aufsteckbewegung aufeinandertreffen. Dadurch wird auf das Erfassungsglied 22 eine der Breite der Stellnocken entsprechende Drehbewegung übertragen, bis die Stellnocken 33 in Nuten zwischen den Gegennocken 34 und die Gegennocken 34 in entsprechende Nuten zwischen den Stellnocken 33 einfahren. In der Endstellung kann das Betätigungsglied 23 zum Beispiel durch Anlage des Kappenbodens an der Endfläche des Austragsstutzens 12 anschlagbegrenzt sein. Damit die Sicherungsnocken 31 nicht in Eingriff mit den Gegennocken 34 gelangen können, sind die Sicherungsnocken 31 an einem erweiterten Endabschnitt 35 des Betätigungsgliedes 23 vorgesehen. Ferner liegen zur Verbesserung der Leichtgängigkeit die Gegennocken 34 etwa im selben Axialbereich wie die Schnappverbindung 26.At a greater distance from the cap opening, the actuating drive 30 also has adjusting cams 33 in the form of approximately axial web projections, which are distributed uniformly over the circumference on the inner circumference of the casing of the actuating member 32. Corresponding counter cams 34 are provided on the outer circumference and only on one end section of the detection element 22. The actuating cams 33 and the counter cams 34 have complementarily inclined end faces with which they meet when the actuating member 23 is secured against rotation during its further pushing-on movement. As a result, a rotational movement corresponding to the width of the actuating cams is transmitted to the detection member 22 until the actuating cams 33 move into grooves between the counter cams 34 and the counter cams 34 into corresponding grooves between the control cams 33. In the end position, the actuating member 23 can be stop-limited, for example, by abutment of the cap base on the end face of the discharge nozzle 12. So that the securing cams 31 cannot come into engagement with the counter-cams 34, the securing cams 31 are provided on an enlarged end section 35 of the actuating member 23. Furthermore, in order to improve the smooth operation, the counter cams 34 are located approximately in the same axial area as the snap connection 26.

Das von dem Stelltrieb 30 weiter entfernte, hintere Ende des Erfassungsgliedes 22 greift in eine stirnseitige Ringnut dadurch ein, daß es am Außenumfang von einem dünnwandigen Abdeckmantel 36 des Grundkörpers 21 umgeben ist. In dessen Bereich ist eine durch die Erfassungseinrichtung 20 gesteuerte Anzeigeeinrichtung 37 vorgesehen, die durch ein Anzeigefenster 38 im Abdeckmantel 36 und eine Skala 40 am Außenumfang des Erfassungsgliedes 22 gebildet ist. Im Anzeigefenster 38 liegt jeweils eines der Skalensymbole frei, während die anderen vom Abdeckmantel 36 unsichtbar abgeschirmt werden. Durch die beschriebene Ausbildung kann das Betätigungsglied 23 mit gleicher Wirkung in zahlreichen verschiedenen relativen Drehlagen aufgesetzt werden. Im aufgesetzten Zustand deckt es mit seinem Endabschnitt 35 auch die Anzeigeeinrichtung 37 am Außenumfang ab. Soll die Anzeige nur bei abgenommener Schutzkappe erkannt werden können, so ist diese im entsprechenden Bereich undurchsichtig; sie kann aber auch wenigstens in diesem Bereich aus durchsichtigem Werkstoff bestehen.The rear end of the detection element 22, which is further away from the actuator 30, engages in an end-face annular groove in that it is surrounded on the outer circumference by a thin-walled cover jacket 36 of the base body 21. In its area, a display device 37 controlled by the detection device 20 is provided, which is formed by a display window 38 in the cover jacket 36 and a scale 40 on the outer circumference of the detection element 22. One of the scale symbols is exposed in the display window 38, while the others are invisibly shielded by the cover 36. Due to the design described, the actuator 23 can be placed with the same effect in numerous different relative rotational positions. In the attached state, its end section 35 also covers the display device 37 on the outer circumference. If the display can only be recognized when the protective cap is removed, it is opaque in the corresponding area; but it can also consist of transparent material at least in this area.

Damit das Erfassungsglied 22 in der jeweils eingestellten Lage nicht nur durch Reibung gesichert ist, kann eine Rastung 39 vorgesehen sein, welche zum Beispiel im Bereich des hinteren Endes am Innenumfang des Erfassungsgliedes 22 und an einer Außenumfangsfläche des Grundkörpers 21 ineinandergreifende Rastzähne aufweist. Sind diese Rastzähne hinsichtlich ihrer Zahnteilung bzw. -verteilung so angeordnet, daß sie am Ende eines Schaltvorganges durch den Stelltrieb 30 nicht vollständig ineinandergreifen, sondern mit Flanken unter Ausübung einer Drehkraft vorgespannt aneinanderliegen, so wird das Erfassungsglied 22 beim Abnehmen des Betätigungsgliedes 23 und Freigeben des Stelltriebes 30 unter dieser Kraft ein kleines Stück weit in der der Schaltbewegung entsprechenden Drehrichtung weitergedreht, so daß beim nachfolgenden Aufsetzen des Betätigungsgliedes 23 die Stellnocken 33 und die Gegennocken 34 mit Sicherheit wieder in Dreheingriff gelangen.So that the detection element 22 is not only secured by friction in the respectively set position, a detent 39 can be provided which, for example, has interlocking locking teeth in the region of the rear end on the inner circumference of the detection element 22 and on an outer circumferential surface of the base body 21. If these locking teeth are arranged with respect to their tooth pitch or distribution so that they do not fully mesh with one another at the end of a switching operation, but rather are biased against one another with flanks while exerting a rotational force, then the detection element 22 becomes when the actuating element 23 is removed and released Actuator 30 rotated a little further under this force in the direction of rotation corresponding to the switching movement, so that when the actuating member 23 is put on again, the actuating cams 33 and the counter cams 34 certainly come into rotary engagement again.

In Fig. 2 ist links die Endlage des Betätigungsgliedes 23a und rechts eine vorangehende Lage dargestellt, die derjenigen nach Fig. 1 entspricht. In Fig. 2 sind für einander entsprechende Bauteile die gleichen Bezugszeichen wie in Fig. 1, jedoch mit dem Index "a" verwendet, weshalb alle Beschreibungsteile sinngemäß für alle Ausführungsformen gelten.2, the end position of the actuating member 23a is shown on the left and a preceding position on the right, which corresponds to that according to FIG. 1. 2, the same reference numerals as in FIG. 1 are used for corresponding components, but with the index "a", which is why all parts of the description apply mutatis mutandis to all embodiments.

Gemäß Fig. 2 ist für die vollständig verkapselte Aufnahme der Austrageinheit 2 ein Futteral 41 aus Grundgehäuse und Deckel vorgesehen. Zweckmäßig ist das Grundgehäuse durch den Grundkörper 21a und der Deckel durch das Betätigungsglied 23a der Erfassungseinrichtung 20a gebildet. Die Austrageinheit 2a ist in den Grundkörper 21a bis zum Anschlag des Speichergefäßes 4a am Boden 42 des Grundkörpers 21a eingesetzt und an dessen Innenumfang nur durch eine vorgespannte Reibungsverbindung 24a gesichert. Der über seine Länge im wesentlichen durchgehend konstante Dicke aufweisende Mantel 28a umgibt die Kappe 19a auch dann auf einem Teil Ihrer Länge, wenn die Austrag-Betätigung 5a in Ausgangsstellung steht, so daß der Gefäßhals 17a von dem Mantel 28a und das Befestigungsglied 15a von der Kappe 19a abgedeckt sind.According to FIG. 2, a case 41 comprising the basic housing and cover is provided for the completely encapsulated reception of the discharge unit 2. The base housing is expediently formed by the base body 21a and the cover by the actuating member 23a of the detection device 20a. The discharge unit 2a is inserted into the base body 21a until the storage vessel 4a stops on the bottom 42 of the base body 21a and is secured on its inner circumference only by a prestressed friction connection 24a. The jacket 28a, which is substantially constant throughout its length, also surrounds the cap 19a over part of its length when the discharge actuation 5a is in the starting position, so that the neck 17a of the jacket 28a and the fastening member 15a of the cap 19a are covered.

Das Erfassungsglied 22a liegt vollständig frei am Außenumfang des Mantels 28a und reicht bis zu dem bundartig über diesen Außenumfang vorstehenden Boden 42. In diesem Fall ist die Skala 40a am Außenumfang des Mantels 28a und das Anzeigefenster 38a im hinteren bzw. unteren Ende des Erfassungsgliedes 22a so vorgesehen, daß es auch dann freiliegt, wenn das Betätigungsglied 23a in Endlage aufgesetzt ist. Der Stelltrieb 30a befindet sich bei dieser Ausbildung im Bereich des erweiterten Endabschnittes 35a und näher bei der Kappenöffnung als die Sicherungsführung 29a, die am offenen Ende des Mantels 28a Sicherungsnocken und Sicherungsnuten aufweist. Das Erfassungsglied 22a reicht nur über einen Teil der Länge des Mantels 28a und liegt im Abstand hinter dessen vorderen bzw. offenen Ende.The detection element 22a lies completely free on the outer circumference of the casing 28a and extends to the bottom 42 which projects like a collar over this outer circumference. In this case, the scale 40a on the outer circumference of the casing 28a and the display window 38a in the rear or lower end of the detection element 22a are so provided that it is exposed even when the actuator 23a is placed in the end position. The actuator 30a is in this training in the region of the enlarged end section 35a and closer to the cap opening than the securing guide 29a, which has securing cams and securing grooves at the open end of the casing 28a. The detection element 22a extends only over part of the length of the jacket 28a and lies at a distance behind its front or open end.
