The liquid dispenser disclosed therein has a liquid reservoir which is integral with the dispenser and together with it constitutes a disposable article. Other typical donors are eg in WO 2015/070935 A1 and WO 2015/003762 A1 disclosed.

AUFGABE UND LÖSUNGTASK AND SOLUTION

Aufgabe der Erfindung ist es, einen Flüssigkeitsspender zur Verfügung zu stellen, der es gestattet, Teile des Spenders nach Entleerung des Flüssigkeitsspeichers wiederzuverwenden.The object of the invention is to provide a liquid dispenser, which allows to reuse parts of the dispenser after emptying the liquid reservoir.

Hierfür wird ein Flüssigkeitsspender für den Austrag von pharmazeutischen oder kosmetischen Flüssigkeiten vorgeschlagen, der wie folgt ausgestaltet ist: Der Flüssigkeitsspender weist einen Flüssigkeitsspeicher zur Aufnahme der Flüssigkeit vor dem Austrag auf. Er weist weiterhin eine Austragöffnung zum Austrag der Flüssigkeit sowie eine Pumpeinrichtung mit Betätigungsfläche zur manuellen Betätigung der Pumpeinrichtung auf, mittels derer Flüssigkeit aus dem Flüssigkeitsspeicher zur Austragöffnung gefördert werden kann.For this purpose, a liquid dispenser for the discharge of pharmaceutical or cosmetic liquids is proposed, which is configured as follows: The liquid dispenser has a liquid reservoir for receiving the liquid prior to discharge. He also has a discharge for discharging the liquid and a pumping device with actuating surface for manual actuation of the pumping device, by means of which liquid can be conveyed from the liquid reservoir to the discharge opening.

Der Flüssigkeitsspeicher ist innerhalb einer wechselbaren Containereinheit vorgesehen, die an eine Haupteinheit, umfassend die Pumpeinrichtung und vorzugsweise auch die Austragöffnung, ankoppelbar und von dieser abkoppelbar ist. Hierfür verfügen die Containereinheit und die Haupteinheit über eine Kopplungseinrichtung, mittels derer die Containereinheit durch Andrücken an die Haupteinheit alternierend an diese ankoppelbar und von dieser lösbar ist. Diese Kopplungseinrichtung verfügt über zwei Kopplungsteileinrichtungen, wobei eine Kopplungsteileinrichtung an der Containereinheit und eine Kopplungsteileinrichtungen an der Haupteinheit vorgesehen ist.The liquid reservoir is provided within a replaceable container unit, which can be coupled to a main unit, comprising the pump device and preferably also the discharge opening, and can be decoupled from this. For this purpose, the container unit and the main unit have a coupling device, by means of which the container unit by pressing against the main unit can be coupled to these alternately and detachable from this. This coupling device has two coupling part devices, wherein a coupling part device is provided on the container unit and a coupling part means on the main unit.

Bei einem erfindungsgemäßen Flüssigkeitsspender ist somit die genannte Containereinheit als Wechseleinheit vorgesehen. Während die Haupteinheit, umfassend die Pumpeinrichtung und vorzugsweise auch die Austragöffnung, bestimmungsgemäß für eine längere Verwendung vorgesehen sind, ist die Containereinheit, die den Flüssigkeitsspender umfasst, dafür vorgesehen, ausgetauscht zu werden. Dies gestattet es zum einen, eine bereits vollständig entleerte Containereinheit gegen eine neue, volle Containereinheit auszutauschen. Darüber hinaus ist es dem Nutzer hierüber auch möglich, verschiedene Container mit gattungsgleichem, jedoch unterschiedlichem Inhalt, beispielsweise verschiedenen Sorten Make-up, anlassbezogen im Wechsel zu verwenden.In a liquid dispenser according to the invention, the said container unit is thus provided as an exchange unit. While the main unit, comprising the pumping means and preferably also the discharge opening, are intended for prolonged use, the container unit comprising the liquid dispenser is intended to be replaced. This makes it possible, on the one hand, to exchange an already completely emptied container unit for a new, full container unit. In addition, it is also possible for the user to use different containers with generic same, but different content, for example, different types of make-up, depending on the occasion alternately.

Gegenstand der Erfindung ist insbesondere, wie die Kopplungseinrichtung zum Ankoppeln der Containereinheit funktioniert. Diese Kopplungseinrichtung ist dafür ausgebildet, durch eine Kraftbeaufschlagung der Containereinheit in Richtung der Haupteinheit sowohl das Ankoppeln als auch das Abkoppeln der Containereinheit zu gestatten. Somit ist sowohl zum Ankoppeln als auch zum Abkoppeln eine übereinstimmende Kraftbeaufschlagung der Containereinheit vorgesehen. Da der Flüssigkeitsspender vorzugsweise eine Stiftform aufweist, entspricht der Ablauf zum Ankoppeln und Abkoppeln dementsprechend quasi dem Ablauf, mit dem bei Druckkugelschreibern im Wechsel die Schreibspitze ausgefahren und wieder eingefahren werden kann.The invention is in particular how the coupling device for coupling the container unit works. This coupling device is designed to allow both the coupling and uncoupling of the container unit by a force application of the container unit in the direction of the main unit. Thus, both for coupling and for uncoupling a matching force application of the container unit is provided. Since the liquid dispenser preferably has a pin shape, the procedure for coupling and uncoupling accordingly corresponds more or less to the sequence with which the writing tip can be extended and retracted alternately in the case of pressure ballpoint pens.

Dieser Ablauf ist insbesondere zweckmäßig, wenn die Haupteinheit über einen Aufnahmeschacht verfügt, in den die Containereinheit eingesetzt wird. Ein solcher Aufnahmeschacht stabilisiert die angekoppelte Containereinheit und kann durch seine Ausgestaltung als Teil der Haupteinheit hochwertiger gestaltet sein als Außenwandungen der bestimmungsgemäß wechselbaren Containereinheit.This procedure is particularly expedient if the main unit has a receiving shaft into which the container unit is inserted. Such a receiving shaft stabilizes the docked container unit and can be designed by its design as part of the main unit higher quality than the outer walls of the intended change container unit.

Wenn so ein Aufnahmeschacht an der Haupteinheit vorgesehen ist, so würde eine Kopplungseinrichtung, die zum Abkoppeln der Containereinheit eine Kraftbeaufschlagung in einer der Einschubrichtung entgegengesetzten Trennrichtung vorsieht, es erforderlich machen, dass die Containereinheit in relevantem Maße aus dem Aufnahmeschacht herausragt, um zum Zwecke des Wechsel ergriffen werden zu können.If such a receiving shaft is provided on the main unit, then a coupling device, which provides for the uncoupling of the container unit to apply force in a direction opposite to the insertion direction separating direction, would require that the container unit protrudes to a relevant extent from the receiving shaft in order to change the to be taken.

Bei der Gestaltung mit einer sowohl zum Ankoppeln als auch zum Abkoppeln vorgesehenen Druckbeaufschlagung der Containereinheit in Richtung der Haupteinheit kann die Containereinheit im angekoppelten Zustand sich hingegen in einer gegenüber dem Rand des Aufnahmeschachtes zurückgesetzten Position befinden und dennoch durch die Öffnung des Aufnahmeschachtes hindurch abkoppelbar sein. Vorzugsweise beträgt das Maß, um das das Ende der Containereinheit zurückgesetzt ist, einige Millimeter.In the design with both intended for coupling and decoupling pressurization of the container unit in the direction of the main unit, the container unit in the coupled state, however, are located in a recessed relative to the edge of the receiving shaft position and yet be decoupled through the opening of the receiving shaft. Preferably, the amount by which the end of the container unit is reset is a few millimeters.

Alternativ zu einer derartigen versenkten Anordnung der Containereinheit im Aufnahmeschacht kann diese jedoch auch in geringem Maße herausragen. Dies kann insbesondere zweckmäßig sein, um von außen erkennen zu können, welcher Art eine Containereinheit eingesetzt ist. Hierfür können verschiedene Containereinheiten an ihrem aus dem Aufnahmeschacht herausragenden Teilbereich eine Farbcodierung aufweisen. Auch eine endseitige Beschriftung des Containers ist jedoch denkbar, so dass man die Art der eingesetzten, gegebenenfalls in einer zurückgesetzten Position befindlichen Containereinheit an dieser im Aufnahmeschacht noch sichtbaren endseitigen Stirnfläche erkennen kann.As an alternative to such a sunk arrangement of the container unit in the receiving shaft, however, this can also protrude to a slight extent. This may be particularly useful to be able to recognize from the outside, which type a container unit is used. For this purpose, various container units may have a color coding on their protruding from the receiving shaft portion. However, an end-side labeling of the container is also conceivable, so that one can recognize the type of container unit used, optionally in a recessed position, at this end-side end face still visible in the receiving shaft.

Die beiden Kopplungsteileinrichtungen sind derart aufeinander abgestimmt, dass sie in einem ineinander eingeschobenen Zustand gegeneinander um eine Drehachse drehbar sind. Die entsprechende Drehachse wird vorzugsweise durch die Geometrie der Kopplungsteileinrichtungen definiert. Alternativ oder zusätzlich können einen Innenwandung des Aufnahmeschachtes und eine Außenwandung der Containereinheit kreisrund ausgestaltet und mit nahezu identischem Durchmesser versehen sein, so dass diese Wandungen die Drehachse definieren.The two coupling part devices are matched to one another in such a way that, in a state inserted into one another, they are rotatable relative to each other about an axis of rotation. The corresponding axis of rotation is preferably defined by the geometry of the coupling part devices. Alternatively or additionally, an inner wall of the receiving shaft and an outer wall of the container unit can be designed circular and provided with almost identical diameter, so that these walls define the axis of rotation.

Vorzugsweise ist an einer der Kopplungsteileinrichtungen mindestens eine Haltenocke vorgesehen und an der anderen Kopplungsteileinrichtung ist eine korrespondierende Haltestruktur mit in Umfangsrichtung durch Unterbrechungen unterbrochene Anschlagsflächen vorgesehen, so dass die Kopplungsteileinrichtungen in einer Relativdrehstellung in Richtung der Drehachse voneinander gelöst werden können, wenn die Haltenocke mit einer Unterbrechung fluchtet. In einer anderen Relativdrehstellung, in der die Haltenocke mit einer Anschlagsfläche fluchtet, sind die Kopplungsteileinrichtungen dagegen gegen axiales Auseinanderziehen gesichert.Preferably, at least one retaining cam is provided on one of the coupling part devices and on the other coupling part means a corresponding support structure is provided with stop surfaces interrupted in the circumferential direction by interruptions so that the coupling part devices can be released from each other in a relative rotational position in the direction of the axis of rotation, if the retaining cam with an interruption flees. In another relative rotational position, in contrast, in which the retaining cam is aligned with a stop surface, the coupling part devices are secured against axial pulling apart.

Gemäß dieser Weiterbildung ist somit vorgesehen, dass zum Zwecke der formschlüssigen Kopplung an einer der Kopplungsteileinrichtungen, vorzugsweise an der Kopplungsteileinrichtung auf Seite der Haupteinheit, Anschlagsflächen vorgesehen sind, die durch Unterbrechungen voneinander getrennt sind. Die auf Seiten der anderen Kopplungsteileinrichtung, also vorzugsweise an der Containereinheit, vorgesehene Haltenocke ist in einer Drehstellung fluchtend zu den Unterbrechungen angeordnet, so dass sie hinter jene Unterbrechungen eintauchen kann. In einer anderen Drehstellung fluchtet sie dann mit den Anschlagsflächen, so dass sie somit gegen unmittelbares Herausziehen formschlüssig gesichert ist.According to this development, it is thus provided that for the purpose of positive coupling to one of the coupling part devices, preferably on the coupling part device on the side of the main unit, stop surfaces are provided which are separated from each other by interruptions. The holding cam provided on the side of the other coupling subassembly, that is preferably on the container unit, is arranged in a rotational position in alignment with the interruptions, so that it can dive behind those interruptions. In another rotational position, it is then aligned with the stop surfaces, so that it is thus secured against direct withdrawal form-fitting.

Grundsätzlich reicht eine Haltenocke aus. Es können jedoch auch mehr Haltenocken vorgesehen sein, die in Umfangsrichtung gegeneinander versetzt sind, insbesondere zwei Haltenocken auf einander gegenüberliegenden Seiten oderfürjede Anschlagsfläche jeweils eine zugeordnete Haltenocke.Basically, a retaining sock is sufficient. However, it may also be provided more retaining cams, which are offset in the circumferential direction against each other, in particular two retaining cams on opposite sides or for each abutment surface in each case an associated retaining cam.

An mindestens einer der Kopplungsteileinrichtungen ist vorzugsweise eine verzahnungsartige Rampenstruktur und an der anderen Kopplungseinrichtung eine hierzu korrespondierende Gegenfläche vorgesehen, durch die die beiden Kopplungseinrichtungen gegeneinander um die Drehachse in eine definierte Sollrelativdrehstellung verdreht werden, wenn sie axial aufeinander zu gedrückt werden. Die Anzahl der in eine der Drehrichtungen wirkenden Einzelrampen der Rampenstruktur stimmt dabei vorzugsweise mit der Summe der Unterbrechungen und der zwischen ihnen vorgesehenen Unterbrechungen überein. Insbesondere vorzugsweise handelt es sich um vier oder mehr in gleicher Drehrichtung angeordnete Rampen an der verzahnungsartigen Rampenstruktur.At least one of the coupling part devices preferably has a tooth-like ramp structure and at the other coupling device a mating surface corresponding thereto is provided, by which the two coupling devices are rotated against each other about the axis of rotation in a defined desired relative rotational position when they are pressed axially towards each other. The number of individual ramps of the ramp structure acting in one of the directions of rotation preferably coincides with the sum of the interruptions and the interruptions provided between them. In particular, it is preferably four or more arranged in the same direction of rotation ramps on the tooth-like ramp structure.

Vorzugsweise ist nicht nur eine Rampenstruktur an einer Kopplungsteileinrichtung vorgesehen, sondern es ist auch die korrespondierende Gegenfläche in Form einer Rampenstruktur vorgesehen. Diese aufeinander zu weisenden Strukturen, die vorzugsweise in Art einer Stirnverzahnung ausgebildet sind, gelangen in Eingriff miteinander, wenn die Containereinheit ausgehend vom angekoppelten oder abgekoppelten Zustand so weit als möglich an die Kopplungsteileinrichtung der Haupteinheit angepresst wird. Diese Soll-Relativstellungen gestatten es, die beiden Kopplungsteileinrichtungen gezielt bezogen auf die Umfangsrichtung zueinander auszurichten, um durch das Anpressen der Kopplungsteileinrichtungen aneinander eine definierte Drehstellung zu bewirken, in der je nach Position der mindestens einen Haltenocke bei einer anschließenden Beabstandung entweder das Einfädeln der Haltenocke in eine Unterbrechung oder das Aufsetzen der Haltenocke auf einer Anschlagsfläche die Folge ist. Da vorzugsweise je ein Zahn der verzahnungsartigen Rampenstruktur zu jeweils einer SollRelativdrehstellung führt, ist vorzugsweise eine korrespondierende Zahl von Unterbrechungen und Anschlagsflächen vorgesehen.Preferably, not only is a ramp structure provided on a coupling part, but also the corresponding counter surface in the form of a ramp structure is provided. These mutually facing structures, which are preferably formed in the manner of a spur gearing, engage with each other when the container unit is pressed from the coupled or disconnected state as far as possible to the coupling part of the main unit. These desired relative positions make it possible to align the two coupling parts specifically with respect to the circumferential direction to one another by pressing the coupling parts to each other to effect a defined rotational position, depending on the position of the at least one retaining cam at a subsequent spacing either the threading Holding cam in an interruption or putting the retaining cam on a stop surface is the result. Since preferably one tooth each of the tooth-like ramp structure leads to a desired relative rotational position in each case, a corresponding number of interruptions and stop surfaces is preferably provided.

An der Haltestruktur sind vorzugsweise in Umfangsrichtung erstreckte schräggestellte Gleitflächen jeweils zwischen den Unterbrechungen und den Anschlagsflächen vorgesehen, wobei in den genannten Sollrelativdrehstellungen die Haltenocke derart relativ zur Haltestruktur ausgerichtet ist, dass sie mit einer der Gleitflächen fluchtet.Preferably, circumferentially extending slanted sliding surfaces are provided on the support structure between the breaks and the abutment surfaces, wherein in the said desired relative rotational positions, the retaining cam is oriented relative to the support structure so as to be aligned with one of the sliding surfaces.

Die Gleitflächen sorgen dafür, dass die Haltenocke oder die Haltenocken, wenn sie auf die Haltestruktur zu bewegt wird, aus den Übergangsbereichen zwischen Anschlagsflächen und Unterbrechungen leicht in Umfangsrichtung versetzt werden, um entweder auf einer Anschlagsfläche aufzusetzen oder in eine Unterbrechung eingeschoben zu werden, so dass die Haupteinheit und die Containereinheit voneinander getrennt werden können.The sliding surfaces ensure that the retaining cam or the retaining cams, when moved towards the support structure, are easily circumferentially offset from the transitional areas between abutment surfaces and interruptions to either seat on a stop surface or be inserted into a break, such that the main unit and the container unit can be separated from each other.

Der bestimmungsgemäße Ablauf bei einer Gestaltung mit einer der bereits erwähnten Rampenstruktur, die Soll-Relativdrehstellungen verursacht, und den beschriebenen Gleitflächen ist der Folgende: Wenn die Containereinheit zum Zwecke des Koppelns erstmals an die Haupteinheit angepresst wird, so durchquert die Haltenocke dabei eine der zwischen den Anschlagsflächen vorgesehenen Unterbrechungen.The intended course in a design with one of the ramp structure already mentioned, the target relative rotational positions caused, and the sliding surfaces described is the following: When the container unit is first pressed against the main unit for the purpose of coupling, the retaining cam thereby crosses one of the between the Stop surfaces provided interruptions.

Wenn die hierfür erforderliche Relativdrehstellung zwischen der Haupteinheit und der Containereinheit einer der Soll-Relativdrehstellungen entsprechen würde, so würde das nachfolgende Anpressen der Kopplungsteileinrichtungen kein Verdrehen der Containereinheit und der Haupteinheit gegeneinander verursachen, so dass eine nachfolgende in Axialtrennrichtung wirkende Kraft dazu führen würde, dass die Containereinheit sich wieder von der Haupteinheit lösen würde.If the required relative rotational position between the main unit and the container unit would correspond to one of the desired relative rotational positions, the subsequent pressing of the coupling subassemblies would not cause any rotation of the container unit and the main unit relative to one another, so that a subsequent force acting in the axial separation direction would cause the Container unit would solve again from the main unit.

Die Drehstellung, in der die Haltenocke durch die Unterbrechung geführt werden kann, ist daher eine, die anschließend aufgrund der Rampenstruktur und der Gegenflächen ein leichtes Verdrehen der Containereinheit und der Haupteinheit gegeneinander verursacht. Dieses Verdrehen reicht aus, um bei einer anschließend stattfindenden entgegengesetzten Relativbewegung in Axialrichtung von der Containereinheit relativ zur Haupteinheit ein Aufsetzen der Haltenocke auf einer der Gleitflächen zu verursachen, wobei diese Gleitfläche derart angestellt ist, dass die Haltenocke nach der leichten Relativdrehbewegung auf einer Anschlagsfläche aufsetzt. Damit ist der gekoppelte Zustand hergestellt.The rotational position in which the retaining cam can be guided through the interruption is therefore one which subsequently causes a slight rotation of the container unit and the main unit against each other due to the ramp structure and the mating surfaces. This twisting is sufficient, in a subsequent relative movement taking place in the axial direction of the container unit relative to the main unit to a placement of the retaining cam on one of the sliding surfaces cause this sliding surface is set such that the retaining cam touches on a stop surface after the slight relative rotational movement. Thus, the coupled state is established.

Wird nun die Containereinheit nochmals an die Haupteinheit angepresst, so kommt es wieder aufgrund des Zusammenwirkens der Rampenstruktur und der Gegenfläche zu einer Relativdrehung zwischen Containereinheit und Haupteinheit, so dass diesmal die Haltenocke bis in eine Relativdrehstellung verschoben wird, von der aus sie anschließend auf eine zur vorgenannten Gleitfläche benachbarte Gleitfläche aufsetzt, die aufgrund ihrer Schrägstellung die Haltenocke in eine Unterbrechung zwischen den Anschlagsflächen führt. Es ist somit sowohl beim Ankoppeln als auch beim Abkoppeln der Containereinheit vorgesehen, dass es jeweils zu einer zweigeteilten rotativen Bewegung kommt, deren erster Teil durch das Anpressen der Kopplungsteileinrichtungen aneinander verursacht wird, und deren zweiter Teil durch das anschließende Abgleiten der Haltenocke an einer der Gleitflächen verursacht wird.If the container unit is then pressed against the main unit again, it will again due to the interaction of the ramp structure and the counter surface to a relative rotation between the container unit and the main unit, so that this time the retaining cam is moved to a relative rotational position, from which they then to a for abuts the aforementioned sliding surface adjacent sliding surface, which leads due to their inclination, the retaining cam in an interruption between the stop surfaces. It is thus provided both when coupling and when uncoupling the container unit that it comes to a two-part rotary movement, the first part is caused by the pressing of the coupling parts together, and the second part by the subsequent sliding of the retaining cam on one of the sliding surfaces is caused.

Es kann weiterhin vorzugsweise eine Federeinrichtung, insbesondere in Form einer Schraubenfeder, vorgesehen sein, die im gekoppelten Zustand der Kopplungseinrichtung zwischen den Kopplungsteileinrichtungen diese in einer Trennrichtung gegeneinander kraftbeaufschlagt.Furthermore, a spring device, in particular in the form of a helical spring, can preferably be provided which, in the coupled state of the coupling device between the coupling part devices, forces it against each other in a separating direction.

Die Federeinrichtung sorgt dafür, dass ein Zusammendrücken der Kopplungsteileinrichtungen nur bei gleichzeitiger Verformung der Federeinrichtung und somit gegen deren Kraft erfolgen kann. Dies führt dazu, dass nach der Kraftbeaufschlagung der Kopplungsteileinrichtungen aufeinander zu die Kopplungsteileinrichtungen sich von selbst wieder leicht voneinander trennen, damit im Zuge dieser Bewegung die Haltenocke auf der Gleitfläche aufsetzen kann.The spring device ensures that compression of the coupling part devices can only take place with simultaneous deformation of the spring device and thus against its force. As a result, after the coupling subassemblies are applied to each other, the coupling subassemblies automatically separate from each other again, so that in the course of this movement the retaining cam can rest on the sliding surface.

Die Federeinrichtung kann insbesondere an einer der Kopplungsteileinrichtungen festgelegt sein und sich in Richtung der anderen Kopplungsteileinrichtung erstrecken. An der anderen Kopplungsteileinrichtung ist vorzugsweise eine Führungsstruktur für die Feder vorgesehen, die die Feder bei Annäherung der Kopplungsteileinrichtungen führt.The spring device can in particular be fixed to one of the coupling part devices and extend in the direction of the other coupling part device. At the other coupling part device, a guide structure for the spring is preferably provided, which guides the spring when approaching the coupling part devices.

Bei einer besonderen Gestaltung ist die die Federeinrichtung einstückig mit einer der Kopplungseinrichtungen ausgebildet. Die Verwendung eines einstückig mit einem vorzugsweise als Kunststoffteil ausgebildeten Teils der Kopplungseinrichtung ist fertigungstechnisch von Vorteil. Obwohl grundsätzlich bevorzugt wird, dass die Federeinrichtung an der der Haupteinheit zugeordneten Kopplungsteileinrichtung vorgesehen ist, kann es bei einer solchen einstückig vorgesehenen Kunststofffeder von Vorteil sein, wenn diese an der Kopplungsteileinrichtung der Containereinheit vorgesehen ist, da hierdurch ihre erforderliche Lebensdauer beschränkt ist und somit Relaxationserscheinungen in der Kunststofffeder weniger Relevanz haben. Findet eine metallische Feder Verwendung, so ist diese vorzugsweise auf Seiten der Haupteinheit festgelegt.In a particular embodiment, the spring device is formed integrally with one of the coupling devices. The use of an integrally formed with a preferably designed as a plastic part of the coupling device is manufacturing technology advantageous. Although it is generally preferred that the spring device is provided on the coupling unit associated with the main unit, it can be provided in such a one-piece provided plastic spring of Be advantageous if it is provided on the coupling part of the container unit unit, as this is their required life is limited and thus Relaxationserscheinungen in the plastic spring have less relevance. If a metallic spring is used, it is preferably fixed on the side of the main unit.

Die Containereinheit verfügt über eine Ausgangsöffnung, durch die die Flüssigkeit in Richtung der Pumpeinrichtung strömen kann. Diese Ausgangsöffnung ist im Lieferzustand vorzugsweise durch eine Membran verschlossen. Zum Öffnen dieses Verschlusses kann an einer der Kopplungsteileinrichtung der Haupteinheit eine Öffnungshülse vorgesehen sein, die beim Ankoppeln der Containereinheit die Membran durchsticht und dadurch die Containereinheit öffnet.The container unit has an outlet opening through which the liquid can flow in the direction of the pumping device. This outlet opening is preferably closed in the delivery state by a membrane. To open this closure can be provided on one of the coupling part of the main unit an opening sleeve which pierces the membrane when coupling the container unit and thereby opens the container unit.

Das Verschließen der Containereinheit mit einer Membran im Lieferzustand ermöglicht es, das Öffnen alleine durch das Einschieben der Containereinheit zu bewirken, indem die Membran gegen die vorzugsweise mit einer Schneidspitze versehene Öffnungshülse gedrückt wird. Eine solche Membran kann einstückiger Teil der containerseitigen Kopplungsteileinrichtung sein oder an dieser angeschweißt oder angeklebt sein. Eine alternative Gestaltung zu einer Membran sieht vor, dass eine Verschlusskugel an der Öffnung der Containereinheit anliegt, die durch leichten Überdruck in der Containereinheit in Position gehalten wird.The closure of the container unit with a membrane in the delivery state makes it possible to effect the opening solely by the insertion of the container unit by pressing the membrane against the preferably provided with a cutting tip opening sleeve. Such a membrane may be an integral part of the container side coupling part means or be welded or glued thereto. An alternative design to a membrane provides that a closure ball rests against the opening of the container unit, which is held in position by slight overpressure in the container unit.

Die Öffnungshülse kann auch dafür genutzt werden, an ihrer Außenseite die Haltenocke oder mehrere Haltenocken anzuordnen.The opening sleeve can also be used to arrange on its outside the retaining cam or more retaining cam.

Zusätzlich zur gesicherten Befestigung der Kopplungsteileinrichtungen aneinander verfügen die Kopplungsteileinrichtungen vorzugsweise auch über eine gemeinsame Klemmeinrichtung, durch die die Kopplungseinrichtung in einer Relativstellung, in der sie gegenüber der formschlüssig gesicherten Relativstellung weiter voneinander beabstandet sind, zueinander fixierbar sind.In addition to the secured attachment of the coupling part devices to one another, the coupling part devices preferably also have a common clamping device, by means of which the coupling device can be fixed relative to one another in a relative position in which they are further spaced apart from the positively secured relative position.

Die Klemmeinrichtung ist eine kraftschlüssig oder formschlüssig wirkende Klemmeinrichtung, die bestimmungsgemäß beim Einschieben und/oder beim Herausziehen der Containereinheit aus der Haupteinheit in einer Zwischenstellung die Haupteinheit und die Containereinheit zueinander lagefixieren, wobei es sich um eine leicht überwindbare Fixierung handelt. Beispielsweise kann die durchstochene Membran in Zusammenwirkung mit der Öffnungshülse diese Klemmenrichtung bilden. Die Containereinheit kann ausgehend von dieser Lage zerstörungsfrei herausgezogen werden. Diese zur eigentlichen gesichert gekoppelten Lage zusätzliche Fixierlage erleichtert das Ankoppeln und Entkoppeln der Containereinheit, da die Containereinheit, selbst wenn sie beim Ankoppeln oder Abkoppeln losgelassen wird, sich nicht selbsttätig von der Haupteinheit trennt und zu Boden fällt, sondern im Bereich der Klemmeinrichtungzunächst hängen bleibt.The clamping device is a force-locking or positive-locking clamping device, which is intended to fix the position of the main unit and the container unit to one another during insertion and / or withdrawal of the container unit from the main unit in an intermediate position, which is an easily overcome fixation. For example, the pierced membrane in cooperation with the opening sleeve can form this terminal direction. The container unit can be pulled out of this location non-destructive. This secured to the actual coupled position additional fixing facilitates coupling and decoupling the container unit, since the container unit, even if it is released when coupling or uncoupling, does not automatically separate from the main unit and falls to the ground, but gets stuck in the area of the clamping device first.

Die Kopplungsteileinrichtung der Haupteinheit ist vorzugsweise als Kunststoffteil ausgebildet, welches mindestens zwei Komponenten ausgewählt aus den Komponenten der Öffnungshülse, eines Festlegungsbereichs für die Federeinrichtung und einer Rampenstruktur in sich vereint. Vorzugsweise sind alle drei Komponenten in dem einen Bauteil vereint. Gegenüberliegend hierzu ist vorzugsweise auch die Kopplungsteileinrichtung an der Containereinheit durch ein einstückiges Bauteil, insbesondere aus Kunststoff, gebildet, welches mindestens zwei und vorzugsweise drei der Komponenten, ausgewählt aus den Komponenten umfassend die Anschlagsflächen, die Gleitflächen und die Rampenstruktur, in sich vereint.The coupling part of the main unit is preferably formed as a plastic part, which combines at least two components selected from the components of the opening sleeve, a fixing area for the spring device and a ramp structure in itself. Preferably, all three components are combined in the one component. Opposite this, the coupling part device is preferably formed on the container unit by a one-piece component, in particular made of plastic, which at least two and preferably three of the components selected from the components comprising the abutment surfaces, the sliding surfaces and the ramp structure in itself.

Das Gehäuse des Flüssigkeitsspenders weist wie eingangs erwähnt vorzugsweise eine Stiftform auf, wobei die Länge ohne Berücksichtigung einer eventuell vorgesehenen Kappe insbesondere vorzugsweise mindestens 100 mm beträgt, vorzugsweise mindestens 120mm, und der maximale Durchmesser insbesondere vorzugsweise höchstens 18 mm beträgt. Die Betätigungsfläche der Pumpeinrichtung kann zur Betätigung insbesondere orthogonal zu einer Haupterstreckungsrichtung des Flüssigkeitsspenders ausgebildet. Zumindest im Bereich der Betätigungsfläche weist der Spender vorzugsweise einen Durchmesser von höchstens 22 mm auf.The housing of the liquid dispenser, as mentioned above, preferably has a pin shape, wherein the length is preferably at least 100 mm, preferably at least 120 mm, without taking into account a possibly provided cap, and the maximum diameter is preferably at most 18 mm. The actuating surface of the pumping device can be designed to operate in particular orthogonal to a main extension direction of the liquid dispenser. At least in the area of the actuating surface, the dispenser preferably has a diameter of at most 22 mm.

Der beschriebene Flüssigkeitsspender dient insbesondere dem Zweck, kosmetische oder pharmazeutische Flüssigkeiten auszutragen. Der Flüssigkeitsspeicher eines erfindungsgemäße Flüssigkeitsspeichers ist vorzugsweise befüllt mit pharmazeutische oder kosmetische Flüssigkeit zur topischen Applikation, mit einem kosmetischen und/oder pharmazeutisches Hautpflegeprodukt, mit einer Make-Up-Flüssigkeit, mit Lip-Gloss, mit Nagellack, mit einer Mascara- oder Lidschattenflüssigkeit oder mit einem Make-Up-Entferner oder Nagellack-Entferner.The liquid dispenser described serves in particular the purpose of discharging cosmetic or pharmaceutical liquids. The liquid reservoir of a fluid reservoir according to the invention is preferably filled with a pharmaceutical or cosmetic liquid for topical application, with a cosmetic and / or pharmaceutical skin care product, with a make-up liquid, with lip gloss, with nail polish, with a mascara or eye shadow liquid or with a make-up remover or nail polish remover.

Je nach Anwendungszweck sind verschiedene Ausgestaltungen betreffend den Applikator denkbar, an dem die Austragöffnung vorgesehen ist. Um dosiert Flüssigkeit verteilen zu können, nachdem diese zuvor bereits ausgetragen wurde, eignet sich eine Applikatorgestaltung mit einem Schwamm oder einer textile Applikationsfläche. Eine solche Applikationsfläche oder auch eine vom Austragkanal durchdrungene Applikationsfläche aus Kunststoff, Keramik oder Metall kann gegenüber der Haupterstreckungsachse des vorzugsweise stiftförmigen Spenders leicht schräggestellt sein, vorzugsweise in einem Winkel zwischen 20° um 70°, um korrespondierend mit der bestimmungsgemäßen Handhabung des Flüssigkeitsspenders in Art eines Stiftes im Betrieb etwas parallel zur Hautoberfläche ausgerichtet zu sein. Anderweitige mögliche Applikatorgestaltung umfassen die Anordnung einer drehbaren Applikationsrolle oder Applikationskugel im Bereich der Austragöffnung, wie es von Deorollern und dergleichen bekannt ist. Je nach Anwendungszweck, beispielsweise für den Austrag von Mascara, ist auch eine Bürste am Applikator zweckmäßig.Depending on the purpose of use, various embodiments relating to the applicator are conceivable, on which the discharge opening is provided. In order to be able to dispense dosed liquid after it has already been discharged, an applicator design with a sponge or a textile application surface is suitable. Such an application surface or also an application surface of plastic, ceramic or metal penetrated by the discharge channel can be slightly inclined relative to the main extension axis of the preferably pin-shaped dispenser, preferably in FIG an angle between 20 ° by 70 °, in order to be aligned parallel to the skin surface corresponding to the proper handling of the liquid dispenser in the manner of a pin during operation. Other possible applicator designs include the placement of a rotatable applicator roll or application ball in the area of the discharge opening, as known from deodorant rollers and the like. Depending on the application, for example for the discharge of mascara, a brush on the applicator is expedient.

DETAILLIERTE BESCHREIBUNG DERAUSFÜHRUNGSBEISPIELEDETAILED DESCRIPTION OF THE EMBODIMENTS

Die Fig. 1 und 2 zeigen einen erfindungsgemäßen Flüssigkeitsspender 10 in einer Gesamtdarstellung.The Fig. 1 and 2 show a liquid dispenser 10 according to the invention in an overall view.

Der Flüssigkeitsspender 10 weist grundsätzlich eine Stiftform auf und ist von außen mit Ausnahme des Applikators 70 und der Betätigungshandhabe 64 äußerlich grundsätzlich rotationssymmetrisch geformt. Bezug nehmend auf Fig. 2, in der der Flüssigkeitsspender 10 in geschnittener Darstellung und mit aufgesetzter Kappe 12 dargestellt ist, werden die Einzelkomponenten beschrieben. Der Flüssigkeitsspender 10 verfügt über eine Haupteinheit 60 mit einem Griffstück 61, an dem die Betätigungshandhabe 64 vorgesehen ist. Diese Betätigungshandhabe 64 ist in einer Durchbrechung 63 des Griffstücks 61 angeordnet und begrenzt eine Pumpkammer 65. Durch elastisches Eindrücken der Betätigungshandhabe 64 kann das Volumen der Pumpkammer 65 reduziert werden, so dass darin befindliche Flüssigkeit durch ein Überdruckventil 65A in Richtung einer Austragöffnung 72 am Applikator 70 gedrückt wird. Wird die Betätigungshandhabe 64 wieder losgelassen, so öffnet sich ein Überdruckventil 65B, welches zwischen der Pumpkammer 65 und einem Flüssigkeitsspeicher 24 vorgesehen ist, so dass unter dem Eindruck der Expansion der Pumpkammer 65 diese mit Flüssigkeit aus dem Flüssigkeitsspeicher 24 aufgefüllt wird.The liquid dispenser 10 basically has a pin shape and externally, with the exception of the applicator 70 and the actuating handle 64, is fundamentally rotationally symmetrical in shape. Referring to Fig. 2 , in which the liquid dispenser 10 is shown in a sectional view and with attached cap 12, the individual components are described. The liquid dispenser 10 has a main unit 60 with a handle 61 on which the actuating handle 64 is provided. This actuating handle 64 is disposed in an opening 63 of the handle 61 and defines a pumping chamber 65. By resiliently pressing the actuating handle 64, the volume of the pumping chamber 65 can be reduced, so that liquid therein through a pressure relief valve 65A toward a discharge port 72 on the applicator 70th is pressed. When the actuating handle 64 is released again, an overpressure valve 65B opens, which is provided between the pumping chamber 65 and a liquid reservoir 24, so that under the impression of the expansion of the pumping chamber 65 it is filled with liquid from the liquid reservoir 24.

Der Flüssigkeitsspeicher 24 ist Teil einer Containereinheit 20, die auf dem der Austragöffnung 72 abgewandten Ende in einen Aufnahmeschacht 66 der Haupteinheit 60 eingeschoben ist. Die Containereinheit 20 verfügt über eine im Weiteren noch näher erläuterte Kopplungsteileinrichtung 32, die im Zustand der Fig. 2 angekoppelt ist an einer haupteinheitsseitigen Kopplungsteileinrichtung 34.The liquid reservoir 24 is part of a container unit 20 which is inserted on the discharge opening 72 facing away from the end in a receiving shaft 66 of the main unit 60. The container unit 20 has a coupling part 32, which will be explained in more detail below, which in the state of Fig. 2 is coupled to a main unit coupling device 34th

Die Fig. 3 zeigt die Haupteinheit 60 und die Containereinheit 20 in getrennter Darstellung. Es ist zu ersehen, dass die Containereinheit 20 aus zwei Bauteilen besteht, nämlich einem endseitig geschlossenen Hülsenbauteil 21, welches das Volumen des Flüssigkeitsspeichers 24 definiert, und einem darauf aufgesetzten Bauteil 23, welches die Kopplungsteileinrichtung 32 zur Verfügung stellt.The Fig. 3 shows the main unit 60 and the container unit 20 in separate representation. It can be seen that the container unit 20 consists of two components, namely a closed end sleeve member 21, which defines the volume of the liquid reservoir 24, and a component 23 placed thereon, which provides the coupling sub 32 available.

In dem Zustand der Fig. 3, in dem die Containereinheit 20 noch nicht eingesetzt wurde, ist eine Ausgangsöffnung 22 der Containereinheit 20 noch verschlossen, wobei hierfür eine Membran 26 vorgesehen ist, die einstückiger Teil mit der containereinheitsseitigen Kopplungsteileinrichtung 32 ist. Die Containereinheit 20 ist somit aufgrund der Verwendung von nur zwei Bauteilen sehr wirtschaftlich herstellbar.In the state of Fig. 3 in which the container unit 20 has not yet been used, an outlet opening 22 of the container unit 20 is still closed, for which purpose a membrane 26 is provided, which is an integral part with the container unit side coupling part 32. The container unit 20 is thus very economical to produce due to the use of only two components.

Die wesentlichen Komponenten der Haupteinheit 60 sind zuvor schon erläutert worden. Bezug genommen wird daher nur auf die haupteinheitsseitige Kopplungsteileinrichtung 34, die über eine mit einer Schneidspitze versehene Öffnungshülse 56 verfügt, welche bestimmungsgemäß beim Einsetzen der Containereinheit 20 die Membran 26 durchstößt.The essential components of the main unit 60 have already been explained. Reference is therefore made only to the main unit-side coupling part means 34, which has a provided with a cutting tip opening sleeve 56, which punctures the intended use of the container unit 20, the membrane 26.

Die beiden Kopplungsteileinrichtungen 32, 34 sind nachfolgend anhand der Fig. 4A bis 4C bzw. 5A bis 5C nochmals erläutert.The two coupling part devices 32, 34 are described below with reference to FIG FIGS. 4A to 4C or 5A to 5C explained again.

Die Fig. 4A bis 4C zeigen die haupteinheitsseitige Kopplungsteileinrichtung 34. Diese weist einen vergleichsweise einfachen Aufbau auf. Eine außenseitige Hülse 51 verfügt stirnseitig über eine verzahnungsartige Rampenstruktur 53 mit insgesamt 12 Zähnen 52, die in Art einer Stirnverzahnung angeordnet sind und jeweils über zwei Einzelrampen 54 verfügen. Zentrisch an der Kopplungsteileinrichtung 34 ist die genannte Öffnungshülse 56 vorgesehen, die bestimmungsgemäß zum Öffnen der genannten Membran vorgesehen ist und als Hohlrohr ausgebildet ist, um Flüssigkeit aus dem Flüssigkeitsspeicher 24 fördern zu können. In Radialrichtung weisen auf gegenüberliegenden Seiten zwei Haltenocken 50 von der Öffnungshülse 56 weg. Die Kopplungsteileinrichtung 34 verfügt darüber hinaus über einen Festlegungsbereich 58 zur Anbringung einer metallischen Schraubenfeder 55.The FIGS. 4A to 4C show the main unit-side coupling part 34. This has a comparatively simple structure. An outer sleeve 51 has frontally a tooth-like ramp structure 53 with a total of 12 teeth 52, which are arranged in the manner of a spur toothing and each have two individual ramps 54. The aforementioned opening sleeve 56 is provided centrally on the coupling part 34 and is intended to open said membrane and is designed as a hollow tube in order to be able to convey liquid from the liquid reservoir 24. In the radial direction have two retaining cams 50 on opposite sides of the opening sleeve 56 away. The coupling part 34 further has a fixing portion 58 for mounting a metallic coil spring 55.

Die in den Fig. 5A bis 5C dargestellte Kopplungsteileinrichtung 32 auf Seiten der Containereinheit 20 verfügt ebenfalls entlang ihres äußeren Umfangs über eine verzahnungsartige Rampenstruktur 43. Von dieser Rampenstruktur 43 umgeben ist eine Innenhülse 47, wobei zwischen der Rampenstruktur 43 und der Innenhülse 47 eine Führungsstruktur 46 zur Aufnahme der genannten Schraubenfeder 55 vorgesehen ist.The in the Figs. 5A to 5C An inner sleeve 47 is surrounded by this ramp structure 43, wherein between the ramp structure 43 and the inner sleeve 47, a guide structure 46 for receiving said coil spring 55 is provided ,

An der Innenseite der Innenhülse 47 ist in Richtung der haupteinheitsseitigen Kopplungsteileinrichtung 34 weisend eine Einführstruktur 48 vorgesehen und auf der gegenüberliegenden Seite eine Haltestruktur40. Die Hattestruktur40 umfasst jeweils sechs Unterbrechungen 41 und sechs Anschlagsflächen 42, wobei jeweils zwischen den Unterbrechungen 41 und den Anschlagsflächen 42 Gleitflächen 45 vorgesehen sind.On the inside of the inner sleeve 47, an insertion structure 48 is provided pointing in the direction of the main unit-side coupling part 34, and a support structure 40 is provided on the opposite side. The hat structure 40 comprises six interruptions 41 and six stop surfaces 42, with sliding surfaces 45 being provided between the interruptions 41 and the stop surfaces 42, respectively.

Das Fügen der Kopplungseinrichtungen 30 bestehend aus den beiden Kopplungsteileinrichtungen 32, 34 ist anhand der Fig. 6A bis 8C verdeutlicht.The joining of the coupling devices 30 consisting of the two coupling part devices 32, 34 is based on the FIGS. 6A to 8C clarified.

Die Fig. 6A bis 6C zeigen eine erste Phase, im Zuge derer die Containereinheit 20 in Richtung des Pfeils 6 in den Aufnahmeschacht 66 eingeschoben wird. Bei der Annäherung der Containereinheit 20 an die Kopplungsteileinrichtung 34 der Haupteinheit 60 wird die Öffnungshülse 56 in die Ausgangsöffnung 22 der Containereinheit 20 eingeschoben und durchstößt die Membran 26. Die Schraubenfeder 55 fährt gleichzeitig in die hierfür vorgesehene Führungsstruktur 46 ein, bis sie im Zustand der Fig. 6A bis 6C deren Grund erreicht, so dass eine fortgesetzte Bewegung der Containereinheit 20 in Richtung der Kopplungsteileinrichtung 34 gegen die Kraft dieser Schraubenfeder erfolgt. Kurz nachdem die Membran durch die Öffnungshülse 56 durchstoßen wurde, fahren die Haltenocken 50 in die Hülse 47 ein und werden von der Einführstruktur 48 in eine von sechs möglichen definierten Drehstellungen gebracht, wobei hierfür die Containereinheit 20 und die Haupteinheit 60 als Ganzes in geringem Umfang ihre Drehstellung zueinander ändern. Beim fortgesetzten Einschieben der Containereinheit 20 gelangen die Rampenstrukturen 43, 53 ab der Stellung der Fig. 7A bis 7C in Eingriff miteinander. Hierdurch kommt es zu einem weiteren Verdrehen der Haupteinheit 60 und der Containereinheit 20 relativ zueinander, bis der Zustand der Fig. 8A bis 8C erreicht ist, in welchem eine Soll-Drehrelativstellung zwischen der Haupteinheit 60 und der Containereinheit 20 erzielt ist. In dieser Soll-Relativstellung sind die Haltenocken 50 fluchtend zu Gleitflächen 45 der Kopplungsteileinrichtung 32 ausgerichtet, wobei es sich um solche Gleitflächen 45 handelt, die abschüssig in Richtung der Anschlagsflächen 42 ausgerichtet sind. Dies führt mit Wegfall der Kraftbeaufschlagung der Containereinheit 20 dazu, dass bei sich entspannender Federeinrichtung 55 die Haltenocken zunächst in Kontakt mit den genannten Gleitflächen kommen, an diesen abgleiten und dann gegen die Anschlagsflächen 42 gedrückt werden. Nun ist eine formschlüssige Sicherung der Kopplungsteileinrichtungen 32, 34 aneinander erzielt.The FIGS. 6A to 6C show a first phase, in the course of which the container unit 20 is inserted in the direction of the arrow 6 in the receiving shaft 66. When approaching the container unit 20 to the coupling part 34 of the main unit 60, the opening sleeve 56 is inserted into the outlet opening 22 of the container unit 20 and pierces the membrane 26. The coil spring 55 moves at the same time in the guide structure provided for this purpose 46 until it is in the state FIGS. 6A to 6C reaches the bottom, so that a continued movement of the container unit 20 in the direction of the coupling part 34 takes place against the force of this coil spring. Shortly after the membrane has been pierced through the opening sleeve 56, the retaining cams 50 move into the sleeve 47 and are brought from the Einführstruktur 48 in one of six possible defined rotational positions, for which the container unit 20 and the main unit 60 as a whole to a limited extent Change rotational position to each other. During continued insertion of the container unit 20, the ramp structures 43, 53 reach from the position of Figs. 7A to 7C engaged with each other. This results in a further rotation of the main unit 60 and the container unit 20 relative to each other until the state of 8A to 8C is achieved, in which a desired rotational relative position between the main unit 60 and the container unit 20 is achieved. In this desired relative position, the retaining cams 50 are aligned in alignment with sliding surfaces 45 of the coupling part device 32, these being those sliding surfaces 45 which are aligned downwards in the direction of the stop surfaces 42. With the elimination of the application of force to the container unit 20, this leads to the fact that, when the spring device 55 relaxes, the retaining cams initially come into contact with the sliding surfaces mentioned, slide on them and are then pressed against the stop surfaces 42. Now a positive locking of the coupling part means 32, 34 is achieved together.

Die nach Entleerung der Containereinheit 20 stattfindende Trennung erfolgt analog.The separation taking place after emptying the container unit 20 takes place analogously.

Ausgehend von dem beschriebenen Zustand, bei dem Haltenocken 50 an den Anschlagsflächen 42 anliegen, erfolgt eine Kraftbeaufschlagung der Containereinheit 20 in gleiche Richtung 6 wie beim Koppeln, also in Richtung der Haupteinheit 60. Hierdurch werden die Haltenocken 50 aus den Vertiefungen der Anschlagsflächen 42 hinausgedrückt und die Rampenstrukturen 43, 53 kommen wieder in Eingriff miteinander. Sie führen wieder zu einem Verdrehen, so dass die Haltenocken wieder fluchtend zu Gleitflächen 45 angeordnet sind,jetzt jedoch zu Gleitflächen 45, die in Richtungvon Unterbrechungen 41 abschüssig ausgerichtet sind. Nun führt der Wegfall der Kraftbeaufschlagung am hinteren Ende der Containereinheit 20 dazu, dass die Haltenocken auf jene beschriebenen Gleitflächen 45 aufgesetzt werden, an diesen abgleiten und somit in die die Unterbrechungen 41 bildenden Kanäle eintauchen.Starting from the described state in which rest holding cam 50 against the abutment surfaces 42, a force is applied to the container unit 20 in the same direction 6 as when coupling, ie in the direction of the main unit 60. As a result, the retaining cams 50 are pushed out of the wells of the stop surfaces 42 and the ramp structures 43, 53 are again engaged with each other. They lead again to a twist, so that the retaining cams are again arranged in alignment with sliding surfaces 45, but now to sliding surfaces 45, which are aligned in the direction of interruptions 41 sloping. Now, the elimination of the application of force at the rear end of the container unit 20 causes the retaining cams are placed on those described sliding surfaces 45, slide on these and thus dive into the interruptions 41 forming channels.

Da diese, wie beispielsweise in Fig. 5B gezeigt, durchgehend gestaltet sind, kann nunmehr die Containereinheit aus dem Aufnahmeschacht 66 der Haupteinheit 60 herausgezogen werden.Because these, such as in Fig. 5B shown, are designed continuously, now the container unit can be pulled out of the receiving shaft 66 of the main unit 60.
