Description

Anwendungsgebiet und Stand der TechnikField of application and state of the art

Die Erfindung betrifft eine Austragvorrichtung für Medien nach dem Oberbegriff von Anspruch 1.The invention relates to a discharge device for media according to the preamble of claim 1.

Eine im Kontext der vorliegenden Erfindung relevante Austragvorrichtung ist beispielsweise aus der in EP 1197266 B1 bekannt.A relevant in the context of the present invention discharge device is for example from the in EP 1197266 B1 known.

Aus der WO 2005/075100 A1 ist eine gattungsgemäße Austragvorrichtung bekannt, bei der zur Betätigung zwei Hebel vorgesehen sind. Ein erster Hebel dient als Betätigungshandhabe und ist zu diesem Zweck am Gehäuse gelagert. Ein zweiter Hebel, mittels dessen die Betätigung des ersten Hebels einen Austragvorgang bewirkt, ist am genannten ersten Hebel schwenkbar angelenkt.From the WO 2005/075100 A1 a generic discharge device is known in which two levers are provided for actuation. A first lever serves as an actuating handle and is mounted for this purpose on the housing. A second lever, by means of which the actuation of the first lever causes a discharge operation, is pivotably articulated on said first lever.

Die zum Stand der Technik bekannten Austragvorrichtungen werden in vielerlei Hinsicht als verbesserungswürdig angesehen.The known in the art discharge devices are considered in many ways to be improved.

Aufgabe und LösungTask and solution

Aufgabe der Erfindung ist es, eine gattungsgemäße Austragvorrichtung weiterzubilden, um insbesondere eine toleranzarme Kraftübertragung von der Austraghandhabe auf den Pumpspender zu erreichen.The object of the invention is to develop a generic discharge, in particular to achieve a low-tolerance power transmission from the discharge to the pump dispenser.

Erfindungsgemäß wird dies durch eine gattungsgemäße Austragvorrichtung erreicht, bei der der erste und der zweite Hebel jeweils mittels eines Lages gelagert sind, wobei die Lager an einem gemeinsamen einstückigen Bauteil vorgesehen sind, wobei das Bauteil vorzugsweise ein Gehäuseabschnitt ist.According to the invention this is achieved by a generic discharge device, wherein the first and the second lever are each mounted by means of a layer, wherein the bearings are provided on a common one-piece component, wherein the component is preferably a housing portion.

Eine Austragvorrichtung mit den gattungsgemäßen Merkmalen gestattet es, einen Pumpspender, der ein Medienspeicher und eine auf dem Medienspeicher aufgesetzte Pumpe umfasst, aufzunehmen. Dieser Pumpspender kann durch Betätigung der als erster schwenkbeweglicher Hebel ausgebildeten Austraghandhabe innerhalb des Gehäuses verschoben werden, wobei ein Betätigungsabschnitt des Pumpspenders, der üblicherweise mit einem Austragrohr des Pumpspenders identisch ist, gegenüber den anderen Bauteilen des Pumpspenders in Richtung der Hauptachse bewegt wird, was eine Betätigung der Pumpe und einen Austragvorrichtung zur Folge hat. Das ausgetragene Medium wird durch eine Austragöffnung, die im Außengehäuse vorgesehen ist, ausgetragen. Die Austragöffnung muss nicht unmittelbar Teil des Außengehäuses sein, sondern kann auch in einer Auslassbaugruppe vorgesehen sein, die mit dem Gehäuse fest verbunden ist. Der Pumpspender ist vorzugsweise als separate Einheit ausgebildet, er kann aber auch integraler Bestandteil der Austragvorrichtung sein. In einem solchen Fall ist es nicht zwingend erforderlich, dass die Pumpe des Pumpspenders und der Medienspeicher fest miteinander verbunden sind. Stattdessen kann der Medienspeicher auch eine feste Lage im Gehäuse einnehmen, während nur die Pumpe während eines Austragvorgangs durch den Träger bewegt und/oder zusammengedrückt wird.A dispensing device with the generic features makes it possible to accommodate a pump dispenser comprising a media reservoir and a pump mounted on the media reservoir. This pump dispenser can be displaced within the housing by actuation of the dispensing handle formed as a first pivotable lever, wherein an actuating portion of the pump dispenser, which is usually identical to a dispensing tube of the pump dispenser, is moved in the direction of the main axis relative to the other components of the pump dispenser, which is actuated the pump and a discharge device result. The discharged medium is discharged through a discharge opening, which is provided in the outer housing. The discharge opening need not be directly part of the outer housing, but may also be provided in an outlet assembly fixedly connected to the housing. The pump dispenser is preferably designed as a separate unit, but it can also be an integral part of the discharge device. In such a case, it is not mandatory that the pump of the pump dispenser and the media storage are firmly connected. Instead, the media reservoir can also occupy a fixed position in the housing, while only the pump is moved and / or compressed during a discharge process by the carrier.

Durch die genannte Anordnung der Schwenkachse des ersten Hebels kann die Austraghandhabe mittels des Daumens der Hand bewegt werden, die die Austraghandhabe umgreift. Dabei bewegen sich die Austraghandhabe und der Daumen während der Betätigung in etwa parallel zueinander, was in ergonomischer Hinsicht von Vorteil ist, da die Krafteinleitung auf den Hebel nicht nur am vordersten Fingerglied des Daumens, sondern über die gesamte Daumenlänge erfolgen kann.By means of said arrangement of the pivot axis of the first lever, the discharge handle can be moved by means of the thumb of the hand, which surrounds the discharge handle. In this case, the Austraghandhabe and the thumb move during operation in about parallel to each other, which is ergonomically advantageous because the force can be applied to the lever not only the foremost phalanx of the thumb, but over the entire length of the thumb.

Unter einer Anordnung der Schwenkachse auf der der Austragöffnung gegenüberliegenden Seite wird insbesondere eine Anordnung verstanden, bei der Abstand zwischen der Schwenkachse und der Austragöffnung bezogen auf die Richtung der Hauptachse mindestens 50% der Länge der Austragvorrichtung beträgt. Insbesondere umfasst sind Ausgestaltungen, bei denen ein der Schwenkachse abgewandtes Ende der Handhabe im Zuge der Betätigung in Richtung der Austragöffnung gedrückt wird und/oder bei denen die Schwenkachse des ersten Hebels, die Austragöffnung und das der Schwenkachse abgewandte Ende der Handhabe ein gedachtes Dreieck bilden, wobei der Innenwinkel an der Schwenkachse im unbetätigten Zustand zwischen 0° und 45°, vorzugsweise zwischen 10° und 30°, beträgt und durch Betätigung verringert wird.An arrangement of the pivot axis on the side opposite the discharge opening is understood in particular to mean an arrangement in which the distance between the pivot axis and the discharge opening, relative to the direction of the main axis, is at least 50% of the length of the discharge device. In particular, embodiments are included in which an end of the handle facing away from the pivot axis is pressed in the direction of the discharge opening in the course of actuation and / or in which the pivot axis of the first lever, the discharge opening and the end of the handle facing away from the pivot axis form a thought triangle; wherein the internal angle at the pivot axis in the unactuated state between 0 ° and 45 °, preferably between 10 ° and 30 °, and is reduced by actuation.

Die Austraghandhabe muss nicht zwingend das durch einen Bediener zum Zwecke der Betätigung unmittelbar berührte Bauteil sein. So wird beispielsweise beim Vorhandensein einer Schutzmembran die Austraghandhabe nur mittelbar berührt. Die Austraghandhabe ist jedoch im Sinne dieser Erfindung stets das erste bei einer Betätigung bewegte Bauteil, welches durch eine definierte Führung zur Bewegung auf einem definierten Bewegungspfad ausgebildet ist.The discharge handle does not necessarily have to be the component directly contacted by an operator for the purpose of actuation. For example, in the presence of a protective membrane, the discharge handle is only indirectly touched. However, in the context of this invention, the discharge handle is always the first component moved during an actuation, which component is formed by a defined guide for movement on a defined movement path.

Die Ausgestaltung der Austraghandhabe und des Übersetzungselement als schwenkbewegliche Hebel ist besonders einfach zu realisieren und führt zu einer hohen Zuverlässigkeit. Bezüglich der Austraghandhabe erlaubt die Gestaltung als schwenkbeweglicher Hebel darüber hinaus eine ergonomisch vorteilhafte Bewegung, bei der die Betätigung mit einem Daumen erfolgt, wobei die Schwenkachse des ersten schwenkbeweglichen Hebels, die Austraghandhabe bildet, in der Nähe der anatomischen Schwenkachse des Daumens liegt.The design of the discharge handle and the translation element as a pivoting lever is particularly easy to implement and leads to a high reliability. With respect to the discharge handle, the pivotable lever design also allows an ergonomically advantageous movement in which the operation is performed with a thumb, wherein the pivot axis of the first pivotable lever that forms the discharge handle is located near the anatomical pivot axis of the thumb.

Das Übersetzungselement als zweiter schwenkbeweglicher Hebel ist dabei weder mit dem Träger noch mit der Austraghandhabe unmittelbar verbunden und führt daher eine vom Träger und der Austraghandhabe unabhängige Bewegung im Zuge der Betätigung der Austraghandhabe aus. Gemeinsam mit der Austraghandhabe und dem Träger bildet das Übersetzungselement ein Getriebe, welches einerseits eine flexiblere Gestaltung der Wirkweise einer Betätigung der Austraghandhabe auf den Träger erlaubt und welches zum anderen auch eine flexiblere Anordnung der Austraghandhabe und ein ergonomischeren Bewegungsablauf bei der Betätigung der Austraghandhabe gestattet. Insbesondere ist es hierdurch möglich, eine konventionelle Mechanik, bei der ein Hebel mit Schwenkachse auf der Seite der Austragöffnung den Träger bewegt, mit einer Austraghandhabe zu kombinieren, die erfindungsgemäß auf der der Austragöffnung abgewandten Seite der Austragvorrichtung schwenkgelagert ist. Eine Betätigung der Austraghandhabe wirkt bei dieser Weiterbildung über einen Berührkontakt unmittelbar auf das Übersetzungselement, welches seinerseits entweder schwenkbeweglich oder linearbeweglich gelagert sein kann. Bei einer Ausgestaltung mit nur einem Übersetzungselement wirkt dieses Übersetzungselement dann auf den Träger und bewegt diesen entlang der Hauptachse auf den ersten gehäusefesten Anschlag zu. Neben der Ausgestaltung des Übersetzungselements als Übersetzungshebel wird auch die Ausgestaltung als translatorisch bewegliches Keilelement oder Kurvenelement als besonders vorteilhaft angesehen.The translation element as the second pivoting lever is connected directly to neither the carrier nor with the discharge handle and therefore performs an independent of the carrier and the discharge movement in the course of actuation of the discharge. Together with the discharge handle and the carrier, the transmission element forms a gear which on the one hand allows a more flexible design of the action of an operation of the discharge on the carrier and which on the other also allows a more flexible arrangement of the discharge and a more ergonomic movement in the operation of the discharge. In particular, this makes it possible to combine a conventional mechanism in which a lever with a pivot axis on the side of the discharge opening moves the carrier with a discharge handle, which according to the invention is pivotally mounted on the side of the discharge device facing away from the discharge opening. An actuation of the discharge handle acts in this development via a contact directly on the transmission element, which in turn can be mounted either pivotable or linearly movable. In an embodiment with only one translation element, this translation element then acts on the carrier and moves it along the main axis to the first housing-fixed stop. In addition to the configuration of the translation element as a translation lever and the design as translationally movable wedge element or curve element considered particularly advantageous.

Die Lagerung des ersten und des zweiten Hebels in einem einstückigen Bauteil ist vorteilhaft, da sie dazu führt, dass die Beabstandung der Schwenkachsen beider Hebel voneinander nur geringe Toleranzen unterworfen ist. Dies macht die Übersetzungsverhältnisse der beiden Hebel sehr gut und reproduzierbar berechenbar.The storage of the first and the second lever in a one-piece component is advantageous because it leads to the fact that the spacing of the pivot axes of both levers is subject to each other only small tolerances. This makes the transmission ratios of the two levers very well and reproducibly calculable.

Bei einer Weiterbildung der Erfindung ist ein Zentrierkonus zum Einführen eines Austragrohrs des Pumpspenders in eine gehäusefeste Aufnahmeausnehmung vorgesehen, wobei der Zentrierkonus axial in Richtung der Hauptachse zumindest zwischen einer ersten Endlage in der er in Richtung des Pumpspenders über die Aufnahmeausnehmung hinausragt, und einer zweiten Endlage, in der er eine Betätigung des Pumpspenders nicht behindert, verschiebbar angeordnet ist.In a further development of the invention, a centering cone for introducing a discharge tube of the pump dispenser is provided in a housing-fixed receiving recess, wherein the centering cone protrudes axially in the direction of the main axis at least between a first end position in which he projects beyond the receiving recess in the direction of the pump dispenser, and a second end position, in which he does not hinder actuation of the pump dispenser, is arranged displaceably.

Insbesondere bei Austragvorrichtungen, deren Gehäuse derart ausgebildet ist, dass der Pumpspender bzw. der Träger mitsamt Pumpspender in Richtung der Hauptachse eingeschoben wird, stellt es ein Problem dar, eine gehäusefeste Aufnahmeausnehmung zur Aufnahme eines Austragrohrs des Pumpspenders zielgenau zu treffen. Dies wird mittels des erfindungsgemäß vorgesehenen Zentrierkonus erleichtert, da dieser über die Aufnahmeausnehmung in Richtung des Trägers und des Pumpspenders hinausragt, so dass der vergrößerte Durchmesser des Zentrierkonus auf seiner dem Pumpspender zugewandten Seite ein leichtes Einführen des Pumpspenders gestattet. Dieser wird dadurch zielgenau in die Aufnahmeausnehmung gelenkt. Durch die verschiebbare Ausgestaltung des Zentrierkonus kann erreicht werden, dass dieser anschließend, insbesondere bei einer ersten Betätigung der Austragvorrichtung, aus seiner ursprünglichen Lage weggeschoben wird, so dass er einer Betätigung des Pumpspenders nicht im Wege steht. Der Zentrierkonus ist vorzugsweise auf einem Austragrohr verschiebbar angeordnet, welches den ersten gehäusefesten Anschlag bildet und/oder in der die Aufnahmeausnehmung ausgebildet ist. Vorzugsweise bildet der Zentrierkonus mit einem Führungselement, insbesondere dem genannten Austragsrohr, eine leichte Presspassung, so dass er gegen einen geringen Reibwiderstand verschiebbar ist.In particular, in discharge devices whose housing is designed such that the pump dispenser or the carrier is pushed along with pump dispenser in the direction of the main axis, it poses a problem to meet a housing-fixed receiving recess for receiving a discharge of the pump dispenser precisely. This is facilitated by means of the centering cone provided according to the invention, since it protrudes beyond the receiving recess in the direction of the carrier and the pump dispenser, so that the enlarged diameter of the centering cone on its side facing the pump dispenser allows easy insertion of the pump dispenser. This is thereby accurately directed into the receiving recess. Due to the displaceable design of the centering cone, it can be achieved that it is subsequently pushed away from its original position, in particular during a first actuation of the discharge device, so that it does not interfere with actuation of the pump dispenser. The centering cone is preferably arranged displaceably on a discharge tube, which forms the first housing-fixed stop and / or in which the receiving recess is formed. Preferably, the centering cone with a guide element, in particular the said discharge tube, forms a slight interference fit, so that it is displaceable against a low frictional resistance.

Bei einer Weiterbildung der Erfindung umfasst das Gehäuse mindestens zwei Gehäuseschalen, die im Bereich von sich im Wesentlichen in einer Haupterstreckungsachse des Gehäuses erstreckenden Verbindungsbereichen zusammensetzbar sind, wobei an beiden Enden der Gehäuseschalen in Richtung der Haupterstreckungsachse Fügeringe vorgesehen sind, die beide Gehäuseschalen umgreifen und relativ zueinander fixieren.In a further development of the invention, the housing comprises at least two housing shells, which can be assembled in the region of connecting areas extending substantially in a main extension axis of the housing, joining rings being provided at both ends of the housing shells in the direction of the main extension axis, which encompass both housing shells and relative to one another fix.

Ein solches Gehäuse erlaubt insbesondere eine einfache Montage der im Gehäuse angeordneten Bauteile der Austragvorrichtung. Diese können in einer ersten Gehäuseschale eingesetzt werden, auf die anschließend die zweite Gehäuseschale aufgesetzt wird, bevor mittels der Fügeringe eine Fixierung beider Gehäuseschalen vorgenommen wird. Die Verbindungsbereiche brauchen sich nicht genau in Richtung der Haupterstreckungsachse zu erstrecken. Erheblich ist jedoch, dass die mindestens zwei Gehäuseschalen sich jeweils bis in der Bereich der Stirnenden der Austragvorrichtung erstrecken, wo sie durch die Fügeringe zusammengehalten werden. Ein Gehäuse dieser Art ist sehr einfach aufgebaut und erlaubt eine unproblematische Montage der im Gehäuse vorgesehenen Bauteile. Es bedarf nicht zwingend thermischer Fügemethoden für die Gehäuseschalen, da je nach konkreter Ausgestaltung schon die Verbindung mittels der Fügeringe ausreicht. Bevorzugt ist es, wenn in den Verbindungsbereichen eine formschlüssige Verbindung der Gehäuseschalen vorgesehen ist, durch die ein Verschieben der Gehäuseschalen gegeneinander verhindert wird.Such a housing allows, in particular, a simple assembly of the components of the discharge device arranged in the housing. These can be used in a first housing shell, on which then the second housing shell is placed before fixing the two housing shells is made by means of the joining rings. The connection areas do not need to extend exactly in the direction of the main axis of extension. It is significant, however, that the at least two housing shells each extend into the region of the front ends of the discharge device, where they are held together by the joining rings. A housing of this type is very simple and allows easy installation of the components provided in the housing. It does not necessarily require thermal joining methods for the housing shells, since, depending on the specific design, the connection by means of the joining rings is sufficient. It is preferred if a positive connection of the housing shells is provided in the connecting regions, by which a displacement of the housing shells against each other is prevented.

Für die Fügeringe sind an den Gehäuseschalen vorzugsweise Aufnahmenuten vorgesehen, die die Fügeringe in axialer Richtung in ihrer Lage fixieren. Die Fügeringe sind bei einer besonderen Ausgestaltung als geschlossene Spannringe ausgebildet, die im zusammengesetzten Zustand der Gehäuseschalen eine Presspassung mit den Gehäuseschalen bilden. Hierzu sind die Fügeringe vorzugsweise aus einem Material gefertigt, was in elastischer Art und Weise verformt werden kann.For the joining rings preferably receiving grooves are provided on the housing shells, which fix the joining rings in the axial direction in their position. The joining rings are formed in a particular embodiment as a closed clamping rings, which form an interference fit with the housing shells in the assembled state of the housing shells. For this purpose, the joining rings are preferably made of a material, which can be deformed in an elastic manner.

Bei einer besonderen Ausgestaltung der Erfindung ist mindestens der Fügering, der an dem der Austragöffnung abgewandten Ende des Gehäuses vorgesehen ist, an einem flächigen Bodenabschnitt einstückig angeformt. Dieses einstückige Bauteil aus Bodenabschnitt und Fügering übernimmt demnach die Doppelfunktion, zum einen die beiden Gehäuseschalen im Bereich des Bodens miteinander zu verbinden und zum anderen das Gehäuse nach unten hin abzuschließen.In a particular embodiment of the invention, at least the joining ring, which is provided at the end of the housing facing away from the discharge opening, integrally formed on a flat bottom portion. This one-piece component from the bottom section and joining ring thus assumes the dual function of connecting the two housing shells together in the area of the floor and of completing the housing towards the bottom.

Besonders bevorzugt sind Ausführungsformen, bei denen an den mindestens zwei Gehäuseschalen jeweils ein Abschnitt eines Aufnahmeraums für einen Applikator vorgesehen ist, wobei die Abschnitte im zusammengesetzten Zustand einen hinterschnittenen Aufnahmeraum zur Fixierung des Applikators bilden. Die Abschnitte der zwei oder mehrere Gehäuseschalen bilden im zusammengesetzten Zustand einen vollständigen Aufnahmeraum, in dem ein Fixierungsabschnitt des Applikators angeordnet ist. Dieser ist aufgrund der Hinterschneidung in seiner Lage fixiert. Diese Ausgestaltung macht es möglich, bis auf den Applikator die gleichen Gehäuseteile für verschiedene Ausführungsformen zu verwenden, die sich lediglich im Hinblick auf den Applikator unterscheiden. Der Fixierungsabschnitt des Applikators ist bei Applikatoren verschiedenen Typs jeweils identisch ausgebildet, während andere Abschnitte des Applikators anwendungsspezifisch individualisiert sein können, beispielsweise in Hinblick auf ihre Formgebung oder die Dimension der Austragöffnung. Bei einer besonders bevorzugten Ausführungsform der Erfindung umfasst der Fügering, der an dem der Auftragöffnung zugewandten Ende des Gehäuses vorgesehen ist, einen Anlageabschnitt zur dichtenden Anlage am Applikator. Dies ist insbesondere bei Applikatoren vorteilhaft, die vom Gehäuse getrennt durch Einsetzen in den Aufnahmeraum mit diesem verbunden werden. Um zu gewährleisten, dass im Bereich des Aufnahmeraums keine Verschmutzungen in das Gehäuse eindringen und keine Flüssigkeit aus dem Gehäuse austreten kann, wird mittels dieses Anlageabschnitts eine abgedichtet Verbindung zwischen Fügering und Applikator geschaffen.Embodiments in which a section of a receiving space for an applicator is respectively provided on the at least two housing shells are particularly preferred, wherein the sections in the assembled state form an undercut receiving space for fixing the applicator. The portions of the two or more housing shells in the assembled state form a complete receiving space in which a fixing portion of the applicator is arranged. This is fixed due to the undercut in its position. This embodiment makes it possible to use, except for the applicator, the same housing parts for different embodiments, which differ only with regard to the applicator. The fixing section of the applicator is in each case identically designed for applicators of different types, while other sections of the applicator may be customized in an application-specific manner, for example with regard to their shape or the dimension of the discharge opening. In a particularly preferred embodiment of the invention, the joining ring, which is provided at the end of the housing facing the application opening, comprises a contact section for sealing contact with the applicator. This is particularly advantageous in applicators, which are separated from the housing by insertion into the receiving space connected thereto. In order to ensure that no dirt can penetrate into the housing in the area of the receiving space and no liquid can escape from the housing, a sealed connection between the joining ring and the applicator is created by means of this contact section.

Vorzugsweise greifen das Übersetzungselement und die Austraghandhabe in einer Richtung senkrecht zur Richtung einer Betätigungsbewegung formschlüssig ineinander. Hierdurch wird verhindert, dass bei einer ungünstigen Richtung der Kraftbeaufschlagung im Zuge der Betätigung ein Abrutschen der Austragshandhabe vom Übersetzungselement erfolgt. Die formschlüssige Verbindung kann insbesondere durch Stege und korrespondierende Nuten erzielt werden, die sich entlang des Weges des Berührkontakts erstrecken.Preferably, the translation element and the discharge handle engage positively in a direction perpendicular to the direction of an actuating movement. This prevents that occurs in an unfavorable direction of the application of force in the course of actuation slipping of the discharge from the translation element. The positive connection can be achieved in particular by webs and corresponding grooves which extend along the path of the contact.

Besonders bevorzugt ist eine Ausgestaltung der Austragvorrichtung, bei der zwischen der Betätigungsbewegung und der Austraghandhabe und der Axialbewegung des Trägers ein nichtlineares Verhältnis besteht. Ein solches nichtlineares Verhältnis ist gegeben, wenn eine Auslenkung der Austraghandhabe um einen definierten Auslenkungsweg oder -winkel in Abhängigkeit von der Lage der Austraghandhabe eine unterschiedlich große Axialbewegung des Trägers zur Folge hat. So kann das Getriebe aus Austraghandhabe, Übersetzungselement und Träger dahingehend ausgestaltet sein, dass zu Beginn der Bewegung der Austraghandhabe ein relativ kleiner Auslenkungsweg der Austraghandhabe zu einem vergleichsweise großen Bewegungsweg des Trägers führt. Dies hat den Vorteil, dass die Betätigungskraft zu Beginn der Betätigung relativ hoch sein muss, was ein Bediener zur Beaufschlagung der Austragvorrichtung mit einer hohen Kraft veranlasst, die ausreicht, um den Austragvorrichtung vollständig abzuschließen.Particularly preferred is an embodiment of the discharge device in which there is a non-linear relationship between the actuating movement and the discharge handle and the axial movement of the carrier. Such a nonlinear relationship exists if a deflection of the discharge handle by a defined deflection path or angle as a function of the position of the discharge handle results in a different axial movement of the carrier. Thus, the transmission can be configured from discharge handle, transmission element and carrier to the effect that at the beginning of the movement of the discharge handle a relatively small displacement of the discharge handle to a comparatively large path of movement of the vehicle leads. This has the advantage that the actuating force at the beginning of the operation must be relatively high, which causes an operator to act on the discharge device with a high force sufficient to complete the discharge device completely.

Bei einer Weiterbildung der Erfindung sind erste Kontaktabschnitte zwischen der Austraghandhabe und dem Übersetzungselement und/oder zweite Kontaktabschnitte zwischen dem Übersetzungselement und dem Träger derart ausgebildet, dass das Widerstandsdrehmoment oder die Widerstandskraft gegen eine Bewegung der Austraghandhabe einen über die Betätigungsbewegung abfallenden Verlauf aufweist. Dies kann neben der Formgebung und der Anordnung der Austraghandhabe, des Übersetzungselements und/oder des Trägers bei einer bevorzugten Weiterbildung der Erfindung durch eine variierende Oberfläche im Kontaktbereich zwischen Austraghandhabe und Übersetzungselement bzw. zwischen Übersetzungselement und Träger erreicht werden. So können die sich berührenden Oberflächen an der Austraghandhabe und im Übersetzungselement bzw. am Übersetzungselement und dem Träger in der unbetätigten Ausgangsstellung der Austraghandhabe einen besonders hohen Haftreibungsbeiwert und/oder Gleitreibungsbeiwert aufweisen. Der Bediener muss dann eine große Kraft aufbringen, um diese Haftreibung bei Beginn der Betätigung zu überwinden. Während der Betätigung verschieben sich die Berührpunkte auf der Austraghandhabe, dem Übersetzungselement und/oder dem Träger, so dass die jeweiligen Berührpunkte in einen Bereich geraten, der sich durch einen besonders geringen Gleitreibungsbeiwert auszeichnet, so dass sich die Reibungsverluste nach Überwinden der Haftreibung in Grenzen halten. Die Oberflächengestaltung kann insbesondere die Rauhigkeit der Oberfläche betreffen.In a further development of the invention, first contact sections between the discharge handle and the transmission element and / or second contact sections between the transmission element and the carrier are designed such that the resistance torque or the resistance force against a movement of the discharge handle has a gradient falling over the actuating movement. This can be achieved in addition to the shape and the arrangement of the discharge, the translation element and / or the carrier in a preferred embodiment of the invention by a varying surface in the contact area between discharge and translation element or between the translation element and the carrier. Thus, the contacting surfaces on the discharge handle and in the translation element or on the transmission element and the carrier in the unactuated initial position of the discharge handle have a particularly high coefficient of static friction and / or Gleitreibungsbeiwert. The operator then has to apply a great deal of force to overcome this stiction when starting to operate. During actuation, the contact points on the discharge handle, the translation element and / or the carrier, so that the respective contact points fall into an area which is characterized by a particularly low coefficient of sliding friction, so that the friction losses after overcoming the static friction is limited , The surface design may relate in particular to the roughness of the surface.

Besonders bevorzugt sind Austragvorrichtungen, bei denen der erste und der zweite Hebel vorzugsweise zu einer gegenläufigen Bewegung im Zuge einer Betätigung der Austraghandhabe ausgebildet sind.Particularly preferred are discharge devices, in which the first and the second lever are preferably designed for an opposite movement in the course of an actuation of the discharge handle.

Eine bevorzugte Weiterbildung der Austragvorrichtung sieht vor, dass die Austraghandhabe durch einen elastischen Wandungsabschnitt abgedeckt ist, der umlaufend mit dem Gehäuse verbunden ist. Dieser elastische Wandungsabschnitt schließt die Austragvorrichtung vorzugsweise hermetisch ab und verhindert somit eine Verschmutzung. Besonders bevorzugte ist es, dass der Wandungsabschnitt stoffschlüssig mit dem Gehäuse verbunden ist, das beispielsweise durch eine Materialauswahl erreicht werden kann, bei der der Wandungsabschnitt aus TPE und das Gehäuse aus PP gefertigt ist.A preferred embodiment of the discharge device provides that the discharge handle is covered by an elastic wall portion which is circumferentially connected to the housing. This elastic wall section preferably closes off the discharge device hermetically and thus prevents contamination. It is particularly preferred that the wall portion is integrally connected to the housing, which can be achieved for example by a choice of materials, in which the wall portion of TPE and the housing is made of PP.

Detaillierte Beschreibung des AusführungsbeispielsDetailed description of the embodiment

Die Fig. 1 bis 6 zeigen eine Ausführungsform einer erfindungsgemäßen Austragvorrichtung. Die Handhabung dieser Austragvorrichtung basiert bezüglich des Austragvorgangs darauf, dass mittels einer Austraghandhabe 152 ein Pumpspender 140 axial gegenüber einem ersten gehäusefesten Anschlag 114b verschoben wird. Dabei ist Position des Pumpspenders relativ zum ersten gehäusefesten Anschlag 114b dabei mittels Rastmitteln 134f, 136a einstellbar, um Bauteiltoleranzen des Pumpspenders 140 und der Bauteile der Austragvorrichtung ausgleichen zu können.The Fig. 1 to 6 show an embodiment of a discharge device according to the invention. The handling of this discharge is based with respect to the discharge process that by means of a discharge handle 152, a pump dispenser 140 is axially displaced relative to a first housing-fixed stop 114b. In this case, the position of the pump dispenser relative to the first housing-fixed stop 114b is adjustable by means of latching means 134f, 136a in order to achieve component tolerances of the pump dispenser 140 and the components of the discharge can compensate.

Bei der Montage wird ausgehend von dem Zustand der Fig. 1 der eingesetzte Träger 132, bestehend aus einem oberen Trägerabschnitt 134 und einem unteren Trägerabschnitt 136, in Richtung der Austragöffnung 122a gedrückt, bis ein oberes Ende 132a des Träger einen zweiten gehäusefesten 112d Anschlag erreicht. Damit einhergehend oder anschließend wird der Träger 132 mittels der Rastmittel 134f, 136a soweit zusammengedrückt, dass das Pumpsystem des Pumpspenders 140 durch Eindrücken eines Austragrohrs 144a des Pumpspenders 140 in seiner betätigten Hubendlage gelangt, während das Austragrohrs 144a am ersten gehäusefesten Anschlag 114a anliegt. Um zu verhindern, dass der obere Trägerabschnitt 134 sich in Folge der Handhabung vor der Montage in eine für die Montage ungeeignete Stellung bringt, ist eine Drehsicherung vorgesehen. Diese besteht aus einem am Gehäuse angeformten und axial erstreckten Steg 118b, der in eine am oberen Trägerabschnitt 134 vorgesehenen Nut 134i eingreift. Bei der Montage kann daher von einer definierten Ausrichtung des oberen Trägerabschnitts 134 ausgegangen werden. Dieser Formschluss des Steges 118b mit der Nut 134i ist in Fig. 6 dargestellt.During assembly, starting from the state of Fig. 1 the inserted support 132, consisting of an upper support portion 134 and a lower support portion 136, pushed in the direction of the discharge opening 122a until an upper end 132a of the carrier reaches a second housing-fixed 112d stop. Along with this or subsequently, the support 132 is compressed by means of the latching means 134f, 136a so far that the pumping system of the pump dispenser 140 passes by pressing a discharge tube 144a of the pump dispenser 140 in its actuated stroke end position, while the discharge tube 144a bears against the first housing-fixed stopper 114a. In order to prevent that the upper support portion 134 brings in consequence of the handling prior to assembly in an unsuitable for mounting position, a rotation lock is provided. This consists of an integrally formed on the housing and axially extending web 118 b, which engages in a provided on the upper support portion 134 groove 134 i. During assembly, therefore, a defined orientation of the upper support section 134 can be assumed. This positive connection of the web 118b with the groove 134i is in Fig. 6 shown.

Der Abschlusszustand der Montage entspricht dem betätigten Zustand, der in Fig. 3 dargestellt ist.The final state of the assembly corresponds to the actuated state which is in Fig. 3 is shown.

Fig. 2 zeigt den unbetätigten Zustand nach der Montage. Ausgehend von diesem Zustand kann durch die Betätigung der Austraghandhabe 152 mittels des Übertragungshebels 160 ein Anheben des Trägers 132 erreicht werden. Von besonderer Bedeutung ist dabei die Anlenkung der Austraghandhabe 152, die im Weiteren noch beschrieben wird. Fig. 2 shows the unactuated state after assembly. Starting from this state, lifting of the carrier 132 can be achieved by the actuation of the discharge handle 152 by means of the transmission lever 160. Of particular importance is the articulation of the discharge handle 152, which will be described below.

Die Wirkverbindung zwischen dem Übertragungshebel 160 und dem Träger 132 wird dabei über zwei in den Zeichnungen nur angedeuteten Schenkel 162 des Übertragungshebels und einen korrespondierenden, ebenfalls nur angedeuteten Vorsprung 132b des Trägers erzielt. Die Schenkel 162 umgreifen einen Hals der Trägers 132 unterhalb des Vorsprungs 132b.The operative connection between the transmission lever 160 and the carrier 132 is achieved via two legs 162 of the transmission lever, which are only indicated in the drawings, and a corresponding projection 132b of the carrier, which is also only indicated. The legs 162 surround a neck of the carrier 132 below the projection 132b.

Fig. 3 zeigt, wie durch Verschwenken des Übertragungshebels 160 der Träger 132 angehoben wird und dabei eine Betätigung des Pumpspenders 140 mittels des ersten gehäusefesten Anschlags 114b erreicht wird. Eine Betätigung über den Zustand der Fig. 3 hinaus ist nicht möglich, da das obere Ende 132a des Trägers 130, welches am zweiten gehäusefesten Anschlag 112d zur Anlage kommt, dies verhindert. Fig. 3 shows how by pivoting the transmission lever 160, the carrier 132 is raised and thereby actuation of the pump dispenser 140 is achieved by means of the first fixed housing stop 114b. An operation on the state of Fig. 3 In addition, it is not possible because the upper end 132a of the carrier 130, which comes to rest on the second housing-fixed stop 112d, prevents this.

Das Gehäuse 112 dieser Ausführungsform der erfindungsgemäßen Austragvorrichtung ist folgendermaßen aufgebaut. Wie der Explosionszeichnung der Fig. 4 entnehmbar ist, weist es zwei Gehäuseschalen 118, 119 auf, die in einer zur Hauptachse 102 weitgehend parallelen Ebene Fügebereiche aufweisen, in denen sie aneinander angesetzt werden. Die Fixierung der Verbindung der beiden Gehäuseschalen 118, 119 erfolgt über zwei Fügeringe 120a, 121, wobei der Fügering 120a, der das Gehäuse 112 der Austragvorrichtung bodenseitig abschließt, einstückig ausgebildet ist mit einem Bodenabschnitt 120b und kleineren Seitenwandungsabschnitten 120c. Der Fügering 120a ist dabei so dimensioniert, dass er mit den Gehäuseschalen 118, 119 eine Presspassung bildet und die beiden Gehäuseschalen somit aneinander anpresst. Die Austragöffnung 122a ist in einem separaten Applikatorbauteil 122 vorgesehen, welches an seinem der Austragöffnung 122a gegenüberliegenden Enden einen Kragen 122b aufweist, der in einer hinterschnittenen Kammer 122c aufgenommen wird, die durch zwei in etwa halbkreisförmige an den Gehäuseschalen 118, 199 angeformte T-Profile 118a, 119a an den Gehäuseschalen 118, 119 gebildet wird. Der zweite Fügering 121 umschließt diese T-Profile und fügt somit im Bereich des Applikators 122 die beiden Gehäuseschalen 118, 119 fest aneinander. Gleichzeitig weist der Fügering 121 einen Dichtabschnitt 121a auf, der an der Außenwandung des Applikatorbauteils 122 dichtend anliegt.The housing 112 of this embodiment of the discharge device according to the invention is constructed as follows. Like the exploded view of the Fig. 4 can be removed, it has two housing shells 118, 119 which have in a plane substantially parallel to the main axis 102 joining regions in which they are attached to each other. The fixing of the connection of the two housing shells 118, 119 via two joining rings 120a, 121, wherein the joining ring 120a, which closes the housing 112 of the discharge on the bottom side, is integrally formed with a bottom portion 120b and smaller Seitenwandungsabschnitten 120c. The joining ring 120a is dimensioned such that it forms a press fit with the housing shells 118, 119 and thus presses the two housing shells against one another. The discharge port 122a is provided in a separate applicator member 122 having at its opposite ends of the discharge port 122a a collar 122b which is received in an undercut chamber 122c formed by two approximately semicircular T-shaped profiles 118a formed on the housing shells 118, 199 , 119a on the housing shells 118, 119 is formed. The second joining ring 121 encloses these T-profiles and thus inserts in the region of the applicator 122, the two housing shells 118, 119 firmly together. At the same time, the joining ring 121 has a sealing portion 121a, which bears sealingly against the outer wall of the applicator component 122.

Die dargestellte Gehäuseform ist besonders einfach zu realisieren und vorteilhaft bei der Montage. Sie ermöglicht es, den Träger 132 in eine der beiden Gehäuseschalen 118, 119 einzulegen und anschließend diese mit der zweiten Gehäuseschale 119, 118 zu verbinden, wodurch die Notwendigkeit entfallen kann, den Träger axial einzufügen. Darüber hinaus erlaubt sie es, die als Betätigungshebel 152 ausgebildete Austraghandhabe und einen Übersetzungshebel 160 in jeweils zwei Lager 119b, 119c einzusetzen, die in der gleichen Gehäuseschale 119 vorgesehen sind. Dies ist zwar grundsätzlich auch bei einem einstückigen Gehäuse denkbar, die elastische Verformbarkeit ist jedoch bei einer einzelnen Gehäuseschale größer als bei einem einstückigen Gesamtgehäuse. Dies erleichtert die Montage, ohne die Stabilität im Betrieb negativ zu beeinflussen.The illustrated housing form is particularly easy to implement and advantageous during assembly. It makes it possible to insert the carrier 132 in one of the two housing shells 118, 119 and then to connect these with the second housing shell 119, 118, whereby the need can be omitted to insert the carrier axially. In addition, it allows to use the actuating handle 152 designed as a discharge handle and a transmission lever 160 in each case two bearings 119 b, 119 c, which are provided in the same housing shell 119. Although this is basically also conceivable for a one-piece housing, the elastic deformability is greater for a single housing shell than for a one-piece overall housing. This facilitates assembly without adversely affecting the stability during operation.

Ein Zentrierkonus 192 ist vor und während der Montage des Trägers 130 in das Gehäuse 112 am unteren Ende des Füllstücks 114 auf dieses aufgeschoben. Dieser Zustand ist in Fig. 1 dargestellt. Beim axialen Einschieben des Trägers 132 in das Gehäuse 112 wird das Austragrohrs 144a des Pumpspenders 140 mittels des Konus 192 eingefangen und so eine einfache Einführung in eine Aufnahmeausnehmung 114a des Füllstücks 114 ermöglicht. Sobald das Austragrohr 144a in der Aufnahmeausnehmung 114a angeordnet ist und der Träger 132 weiter in das Gehäuse 112 eingeschoben wird, kommt ein Deckel 141 des Pumpspenders 140 selbst in Kontakt mit dem Zentrierkonus 192 und schiebt diesen im Zuge des weiteren Einschiebens des Pumpspenders und des Trägers dabei auf dem Füllstück 114 in Richtung der Austragöffnung 122a nach oben. Die Endlage des Zentrierkonus 192 wird dann erreicht, wenn ein oberes Ende 132a des Trägers 132 an einem zweiten gehäusefesten Anschlag 112d ankommt. Der Zentrierkonus gelangt dadurch in einen Bereich, in dem er für den weiteren Betrieb der Austragvorrichtung nicht störend ist.A centering cone 192 is slid onto the housing 112 at the lower end of the filler 114 prior to and during assembly of the carrier 130. This condition is in Fig. 1 shown. When the carrier 132 is pushed axially into the housing 112, the dispensing tube 144a of the pump dispenser 140 is captured by means of the cone 192 and thus allows easy insertion into a receiving recess 114a of the filling piece 114. As soon as the discharge tube 144a is arranged in the receiving recess 114a and the carrier 132 is pushed further into the housing 112, a lid 141 of the pump dispenser 140 itself comes into contact with the centering cone 192 and pushes it in the course of the further insertion of the pump dispenser and the carrier on the filler 114 in the direction of the discharge opening 122a upwards. The end position of the centering cone 192 is then achieved when an upper end 132a of the carrier 132 arrives at a second fixed housing stop 112d. The centering cone thereby enters an area in which it is not disturbing for the further operation of the discharge device.

Diese Endlage des Zentrierkonus 192 ist der Fig. 2 zu entnehmen. Da die Endlage des Trägers 132 während der Montage auch der Endlage des Trägers 132 während der Betätigung, dargestellt in Fig. 3, entspricht, nimmt der Zentrierkonus 192 im Betrieb keinerlei Einfluss auf die Betätigung.This end position of the centering cone 192 is the Fig. 2 refer to. Since the end position of the carrier 132 during assembly also the end position of the carrier 132 during the operation, shown in FIG Fig. 3 , corresponds, the centering cone 192 does not affect the operation in operation.

Besonderheiten an der dargestellten Austragvorrichtung liegen insbesondere in der Gestaltung und der Lagerung der Austraghandhabe 152 sowie in dem Vorhandensein des Übertragungshebels 160. Der Betätigungsmechanismus der Austragvorrichtung umfasst den Betätigungshebel 152, den Übersetzungshebel 160 und den Träger 132. Wie die Fig. 2 und 3 zeigen, kann durch Eindrücken des Betätigungshebels 152 mittelbar auch der Übertragungshebel 160 verschwenkt werden, wobei der Drehsinn der beiden Hebelbewegungen zueinander gegenläufig ist. Diese Ausgestaltung mit zwei Hebeln erlaubt die einfache Realisierung von nichtlinearen Übertragungsverhältnissen. Bei der konkreten Ausgestaltung des zweiten Ausführungsbeispiels führt dies dazu, dass zu Beginn der Betätigung des Betätigungshebels 152 ein Verschwenken um einen definierten Winkel bezüglich des Betätigungshebels 152 ein vergleichsweise starkes Verschwenken des Übertragungshebels 160 zur Folge hat. Gegen Ende der Betätigungsbewegung führt der Übertragungshebel 160 beim einem Verschwenken des Betätigungshebels 152 um den gleichen Winkel eine deutlich verringerte Schwenkbewegung durch. Die Folge ist, dass die Kraft, die ein Bediener aufwenden muss, um die Austragvorrichtung der Fig. 1 bis 3 zu betätigen, eingangs größer ist als gegen Ende. Die erhöhte Kraft, die eingangs aufgebracht wird, führt dazu, dass die Gefahr vermindert wird, dass der Bediener im Laufe des Austragvorgangs die Kraft auf null reduziert und den Austragvorgang dadurch unvollendet lässt. Um den erforderlichen Kraftaufwand zu Beginn weiter zu erhöhen, kann der Oberflächenabschnitt 152f des Betätigungshebels 152, in dem der Berührpunkt zum Übertragungshebel 160 zu Beginn des Austragvorgangs ist, gegenüber einem Oberflächenbereich 152g, in dem sich der Berührpunkt im späteren Verlauf des Austragvorgangs befindet, unterschiedlich ausgeprägt sein. So bietet es sich an, im Bereich 152f die Oberfläche beispielsweise hinsichtlich ihrer Rauhigkeit oder auch ihrer Formgebung so zu gestalten, dass ein hoher Haftreibungsbeiwert mit dem Übertragungshebel 160 empfiehlt wird. In dem Bereich 152g ist hingegen auf einen geringen Gleitreibungsbeiwert zu achten, so dass nur geringe Reibungsverluste einem Weiterführen der Bewegung entgegenstehen.Particularities of the dispensing device shown are in particular in the design and the storage of the discharge handle 152 and in the presence of the transmission lever 160. The actuating mechanism of the discharge comprises the actuating lever 152, the transmission lever 160 and the carrier 132. Like the Fig. 2 and 3 show can be indirectly pivoted by pressing the operating lever 152 and the transmission lever 160, wherein the direction of rotation of the two lever movements are opposite to each other. This embodiment with two levers allows the simple realization of non-linear transmission ratios. In the concrete embodiment of the second embodiment, this leads to the fact that at the beginning of the actuation of the actuating lever 152 pivoting about a defined angle with respect to the actuating lever 152 has a relatively strong pivoting of the transmission lever 160 result. Towards the end of the actuating movement, the transmission lever 160 performs a significantly reduced pivoting movement when the actuating lever 152 is pivoted by the same angle. The result is that the force that an operator must expend to the discharge of the Fig. 1 to 3 to operate, initially larger than towards the end. The increased force applied at the outset results in a reduced risk of the operator walking over the discharge process reduces the force to zero and thus leaves the discharge process unfinished. To further increase the required force initially, the surface portion 152f of the operating lever 152, in which the point of contact with the transfer lever 160 at the beginning of the discharging operation, is different from a surface portion 152g in which the contact point is later in the discharging operation be. For example, it makes sense to design the surface in the area 152f, for example with respect to its roughness or its shape, in such a way that a high static friction coefficient with the transmission lever 160 is recommended. On the other hand, in the region 152g, attention must be paid to a low coefficient of sliding friction so that only slight frictional losses preclude continuing the movement.

Die Gestaltung mit zwei Hebeln, einem Betätigungshebel 152 und einem Übertragungshebel 160, hat darüber hinaus weitere Vorteile. So erlaubt es die Verwendung zweier Hebel 152, 160, die Schwenkachse 103 des Betätigungshebels 152 an dem der Austragöffnung 122a abgewandten Ende der Austragvorrichtung vorzusehen. Dies ist von Vorteil, da es eine Betätigung des Betätigungshebels 152 mit einem Daumen gestattet, wobei der Daumen und der Betätigungshebel 152 über den vollständigen Betätigungsvorgang in etwa parallel zueinander liegen. Die Kraft, die vom Daumen aufgebracht wird, kann dadurch über die komplette Länge des Hebels 152 statt nur in einem kurzen Abschnitt aufgebracht werden. Dies ist unter ergonomischen Gesichtspunkten von Vorteil.The design with two levers, an actuating lever 152 and a transmission lever 160, has further advantages. Thus, the use of two levers 152, 160 makes it possible to provide the pivot axis 103 of the actuating lever 152 at the end of the discharge device facing away from the discharge opening 122a. This is advantageous because it allows actuation of the actuating lever 152 with a thumb, with the thumb and the actuating lever 152 approximately parallel to each other throughout the complete actuation process. The force applied by the thumb can thereby be applied over the entire length of the lever 152 instead of just in a short section. This is advantageous from an ergonomic point of view.

Der Betätigungshebel 152 und der Übertragungshebel 160 sind in zwei Perspektiven auch der Fig. 5 zu entnehmen. Zu erkennen ist, dass der Betätigungshebel 152 eine Außenfläche 152h und daran anschließend drei nach innen gewandte Rippen 152i, 152j, 152k aufweist. Diese Bauform bietet eine hohe Stabilität bei geringem Materialaufwand. Korrespondierend zur mittleren Rippe 152j ist am Übertragungshebel 160 zwischen zwei Kontaktzungen 160a eine Ausnehmung 160b vorgesehen. Die Kontaktzungen 160a greifen in die Aussparungen zwischen den Rippen 152h, 152i, 152j ein, während gleichzeitig die mittlere Rippe 152i in die Ausnehmung 160b eingreift. Hierdurch wird eine formschlüssige Verbindung in einer Richtung quer zu Betätigungsrichtung geschaffen. Ein Abgleiten des Betätigungshebels 152 vom Übertragungshebel 160 in dieser Richtung 166 ist daher nicht zu befürchten.The operating lever 152 and the transmission lever 160 are also in two perspectives Fig. 5 refer to. It can be seen that the actuating lever 152 has an outer surface 152h and thereafter three inwardly facing ribs 152i, 152j, 152k. This design offers high stability with low material costs. Corresponding to the middle rib 152j is on the transfer lever 160 between two contact tongues 160a a recess 160b provided. The contact tongues 160a engage in the recesses between the ribs 152h, 152i, 152j, while at the same time the middle rib 152i engages in the recess 160b. As a result, a positive connection is created in a direction transverse to the direction of actuation. A sliding of the actuating lever 152 from the transmission lever 160 in this direction 166 is therefore not to be feared.

Als Schutz vor Verunreinigungen ist über der Austraghandhabe 152 eine elastische und im Zuge der Betätigung verformbare Membran 164 vorgesehen. Die elastische Membran stellt eine sehr vorteilhafte Möglichkeit zur Herstellung einer Abdichtung an der Austragshandhabe dar, die besonders kleine Austragvorrichtungen gestattet, da sie das Erfordernis entfallen lässt, zur Abdichtung die Austraghandhabe mit abdichtenden Seitenflächen zu versehen, die bei einer Betätigung in das Gehäuse eintauchen und dort Aufnahmeplatz beanspruchen.As a protection against contamination, an elastic and deformable in the course of actuation membrane 164 is provided on the Austraghandhabe 152. The elastic membrane is a very advantageous possibility for producing a seal on the discharge handle, which allows particularly small discharge devices, since it eliminates the need to provide for sealing the discharge handle with sealing side surfaces, which are immersed in an operation in the housing and there Take up space.
