Definitions
- the invention relates to a discharge device for media according to the preamble of claim 1.
- a generic discharge device is for example from the documents WO / 03851 A1 .
- EP 1 197 266 B1 discloses a discharge device for media.
- the known in the art discharge devices are considered in many ways to be improved. For example, it is considered disadvantageous that it is due to the mostly exposed Handle can easily come to an unintentional actuation of the discharge.
- the object of the invention is to develop a generic discharge and a generic assembly method for a discharge to reduce the existing disadvantages in the prior art.
- 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 by actuation of the discharge handle within the housing, wherein an actuating portion of the pump dispenser, which is usually identical to a dispensing tube of the pump dispenser, is moved relative to the other components of the pump dispenser in the direction of the main axis, which means an actuation of the pump and a discharge device entails.
- 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 one In such a case, it is not absolutely necessary 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.
- a reversible discharge device has advantages, especially in the transport of the discharge device. This applies both to the one-time transport by the end user as well as for mass transport.
- the discharge device In the activated operating state, the discharge device can be used in a normal manner, so that an actuation of the discharge handle leads to a desired discharge process.
- an actuation of the discharge handle can be blocked. This means that the discharge handle from a rest position can not be moved and thus no accidental movement can take place.
- a decoupling of the discharge handle from the carrier may also be provided in the deactivated operating state. This decoupling refers to the operative connection in the axial direction. Such a decoupling has the consequence that the discharge handle can indeed be moved, but this has no influence on the position of the carrier within the housing. Thus, the risk of a discharge is not given.
- linearly or rotatably movable switch For switching a relative to the housing or a main component of the housing linearly or rotatably movable switch is provided, which enables the desired deactivation by locking the handle or decoupling the handle from the carrier.
- the discharge handle is arranged in the deactivated operating state in a space-saving stowed position.
- the discharge handle In this stowage position, the discharge handle is preferably tight against the housing of the discharge device.
- a space-saving stowage position facilitates transport, which is advantageous both for individual transport and for mass transport.
- the discharge device has a protective cap which can only be placed when the discharge handle is in its stowed position. The risk that a user forgets the transfer of the discharge in its deactivated operating state is thereby reduced.
- the discharge handle in the activated state is not movable into the stowage position.
- the axial active coupling between the discharge handle and the carrier is designed for this purpose so that when this active coupling the discharge handle does not reach the stowed position both in the actuated and in the unactuated activated state.
- Such a design ensures that the discharge device is not accidentally transferred, for example by movement in connection with the transport of the discharge on the deactivated operating state in the actuated activated operating state.
- Such an unintentional transfer of the discharge in the activated operating state would have on the one hand in the assembly disadvantages and on the other hand would be an actuation and leak-free transport is no longer guaranteed.
- the operating state is controllable by a rotational movement of the carrier about the main axis, wherein in at least a first angle section, the axial operative connection between the carrier and the discharge handle and interrupted in at least a second angle section, the axial operative connection between the carrier and the discharge handle is.
- a relative rotation between the discharge and the carrier can be used to determine the operating condition.
- the carrier is rotated relative to the housing with discharge handle.
- first and the second angle section together occupy an angle of not more than 90 °, so that even with a comparatively small movement of the operating state can be changed.
- first angle section there is an axial operative connection, so that an actuation of the discharge handle results in a translational movement of the carrier, which in turn leads to a discharge process via a movement of the pump dispenser.
- this axial operative connection between carrier and discharge handle is interrupted, this being possible by a complete decoupling of the carrier from the discharge handle or else by a decoupling only with regard to the axial component.
- Particularly preferred embodiments are those in which in a third angle section an axial locking connection between the carrier and the discharge handle, by which the discharge handle is held in a blocking position.
- This locking position preferably corresponds to the stowed position of the discharge handle.
- the design of the carrier with respect to the third angle section can ensure that the discharge handle remains in this stowed position in the deactivated operating state, so that the discharge device has an advantageous low expansion, and also prevents the discharge handle from interfering with it is freely movable in the decoupled state.
- the carrier has an operative connection section for interacting with the discharge handle, wherein the active connection section has at least one radially extending recess, into which, in the activated operating state, a guide extension connected to the discharge handle protrudes.
- the guide extension is adapted to be moved in the activated operating state by means of the discharge in the direction of the first housing fixed stop, which together with the guide extension and the active connection portion of the carrier and thus the carrier is moved in the direction of the first housing fixed stop.
- the recess is designed as a simple free space under a projection extending radially from the carrier.
- the active coupling between the discharge handle and the carrier is that the movement of the guide extension of the discharge by means of a force in the projection causes a corresponding movement of the carrier and an associated pump actuation, while in the opposite direction no corresponding active coupling exists.
- the recess is closed on the operative connection portion of the carrier in both directions of the main axis, so that there is a forced coupling acting in both directions between the carrier and the guide extension of the discharge in the activated operating state.
- the active connection portion has an at least partially cylindrical shape which extends in the direction of the main axis, wherein the recess is formed as a control curve which extends on a lateral surface of the operative connection portion.
- the control cam assigns each rotational position of the carrier in the unactuated position and thus its Wirkharmsabterrorisms a corresponding position of the discharge to. By rotating the carrier and thus the active connection section, it is determined where the discharge handle-side guide extension is located on the control curve.
- control cam is preferably configured such that it has in the first angle section a first control cam section which extends on the outer surface of the active connection section in a plane orthogonal to the main axis and / or in the second angular section has a second control section which extends on the outer surface of the operative connection section axially relative to the main pocket and extending in the circumferential direction relative to the outer surface of the gate section and / or in the third angular section having a third cam section extending on the outer surface of the operative connection section in a plane orthogonal to the main axis.
- this positive coupling is such that a movement range of the discharge handle is assigned a movement range of the carrier, this movement range of the carrier is tuned to the pump stroke of the pump in the pump dispenser and its position relative to the first housing-fixed stop.
- the positive coupling between the carrier and the discharge handle is preferably designed such that movement of the discharge handle is not possible. This is achieved by arranging the carrier at its end position opposite the first housing-fixed stopper, which preferably is defined by a counterstay fixed to the housing is.
- the cam is preferably formed in the second cam portion so that it connects the first cam portion and the third cam portion together and extends for this purpose in approximately helix portion-shaped on an outer surface of the operative connection portion. If the guide extension of the discharge handle is located in this second cam section, a movement of the discharge handle only leads to a rotation of the carrier or of the active connection section, although there is no axial displacement of the carrier. It is therefore when the guide extension is arranged in the second cam section or in the third cam section, it is not possible to effect a change in position of the carrier in the axial direction.
- the discharge device can be switched by means of an activation handle between the activated operating state and the deactivated operating state.
- an activation handle may be utilized by a user prior to using the dispenser, and to transfer the dispenser to the activated operating state.
- the activation handle is a second handle in addition to the discharge handle.
- an activation handle which is designed to be rotatable and is operatively connected to the carrier in a rotationally coupled manner.
- the activation handle can be part of the carrier or with be identical so that it is handled directly by the operator to change the operating state of the discharge.
- an activation handle which is operatively connected via a coupling with the carrier, which offers the advantage that the axial movement of the carrier due to an actuation of the discharge does not simultaneously axial movement of the activation handle result.
- the activation handle is connected to the carrier by means of a slip clutch.
- a slip clutch allows the operator to actuate the activation handle without having to take account of an end position, since, after reaching the activated or deactivated operating state, a further moving activation handle leads to a preferably perceptible slippage of the slip clutch.
- this has a toothing whose teeth are so far elastically deformable at least in part when a defined resistance torque is exceeded, that they fall out of engagement.
- This represents a very inexpensive form of a slip clutch, which also has the advantage that upon reaching the slip range characteristic noise generated by the sliding teeth of the teeth, indicating the user that he has reached the activated or deactivated operating state ,
- an activation handle which is designed as a section of the outer housing, in particular as a rotatable bottom portion. This represents a technically simple realization that Moreover, in terms of material savings is beneficial.
- the design as a rotatable bottom portion is advantageous because such an activation handle can hardly be confused with a usually lever-like discharge handle, which facilitates the operation for the end user.
- the discharge device has a protective cap, which preferably prevents the transfer of the discharge device into the activated operating state in a functional state.
- the protective cap In this functional state, in which the protective cap is placed on the discharge device, it preferably surrounds a region in which the discharge handle is provided, which requires that the discharge handle is in the jam state.
- This design of the protective cap leads to the fact that an accidental transfer of the discharge in the activated operating state is not accidentally possible with attached protective cap. On the other hand, it also ensures that a user is prompted to return the discharge after use in the deactivated mode, so that he can put the cap back on the discharge.

Description
Die Erfindung betrifft eine Austragvorrichtung für Medien gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a discharge device for media according to the preamble of claim 1.
Eine gattungsgemäße Austragvorrichtung ist beispielsweise aus den Dokumenten
Die zum Stand der Technik bekannten Austragvorrichtungen werden in vielerlei Hinsicht als verbesserungswürdig angesehen. So wird insbesondere als nachteilig angesehen, dass es aufgrund der zumeist exponierten Handhabe leicht zu einer unbeabsichtigten Betätigung der Austragvorrichtung kommen kann.The known in the art discharge devices are considered in many ways to be improved. For example, it is considered disadvantageous that it is due to the mostly exposed Handle can easily come to an unintentional actuation of the discharge.
Aufgabe der Erfindung ist es, eine gattungsgemäße Austragvorrichtung sowie ein gattungsgemäßes Montageverfahren für eine Austragvorrichtung weiterzubilden, um die im Stand der Technik vorhandenen Nachteile zu vermindern.The object of the invention is to develop a generic discharge and a generic assembly method for a discharge to reduce the existing disadvantages in the prior art.
Erfindungsgemäß wird dies durch eine Austragvorrichtung gemäß dem Anspruch 1.This is achieved by a discharge device according to claim 1.
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 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 by actuation of the discharge handle within the housing, wherein an actuating portion of the pump dispenser, which is usually identical to a dispensing tube of the pump dispenser, is moved relative to the other components of the pump dispenser in the direction of the main axis, which means an actuation of the pump and a discharge device entails. 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 one In such a case, it is not absolutely necessary 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.
Eine erfindungsgemäße umschaltbare Austragvorrichtung hat vor allem bei dem Transport der Austragvorrichtung Vorteile. Dies gilt sowohl für den Einzeitransport durch den Endverbraucher als auch für den Massentransport. Im aktivierten Betriebszustand kann die Austragvorrichtung in normaler Art und Weise verwendet werden, so dass eine Betätigung der Austraghandhabe zu einem gewünschten Austragvorgang führt. Zu diesem Zweck besteht eine axiale Wirkkopplung zwischen der Austraghandhabe und dem Träger im aktivierten Zustand. Im deaktivierten Betriebszustand kann eine Betätigung der Austraghandhabe gesperrt sein. Dies bedeutet, dass die Austraghandhabe aus einer Ruhelage nicht bewegt werden kann und somit auch keine versehentliche Bewegung stattfinden kann. Alternativ zur Sperrung der Austraghandhabe kann im deaktivierten Betriebzustand auch eine Entkopplung der Austraghandhabe vom Träger vorgesehen sein. Diese Entkopplung bezieht sich auf die Wirkverbindung in axialer Richtung. Eine derartige Entkopplung hat zur Folge, dass die Austraghandhabe zwar bewegt werden kann, wobei dies jedoch keinen Einfluss auf die Position des Trägers innerhalb des Gehäuses hat. Damit ist auch die Gefahr eines Austragvorgangs nicht gegeben.A reversible discharge device according to the invention has advantages, especially in the transport of the discharge device. This applies both to the one-time transport by the end user as well as for mass transport. In the activated operating state, the discharge device can be used in a normal manner, so that an actuation of the discharge handle leads to a desired discharge process. For this purpose there is an axial active coupling between the discharge handle and the carrier in the activated state. In the deactivated operating state, an actuation of the discharge handle can be blocked. This means that the discharge handle from a rest position can not be moved and thus no accidental movement can take place. As an alternative to blocking the discharge handle, a decoupling of the discharge handle from the carrier may also be provided in the deactivated operating state. This decoupling refers to the operative connection in the axial direction. Such a decoupling has the consequence that the discharge handle can indeed be moved, but this has no influence on the position of the carrier within the housing. Thus, the risk of a discharge is not given.
Zum Umschalten ist ein gegenüber dem Gehäuse oder einem Hauptbestandteil des Gehäuses linear- oder drehbeweglicher Schalter vorgesehen, der durch Sperren der Handhabe oder Entkoppeln der Handhabe vom Träger die gewünschte Deaktivierung ermöglicht.For switching a relative to the housing or a main component of the housing linearly or rotatably movable switch is provided, which enables the desired deactivation by locking the handle or decoupling the handle from the carrier.
Bei einer Weiterbildung der Erfindung ist die Austraghandhabe im deaktivierten Betriebszustand in einer platzsparenden Staustellung angeordnet. In dieser Staustellung liegt die Austraghandhabe vorzugsweise eng an dem Gehäuse der Austragvorrichtung an. Eine platzsparende Staustellung erleichtert den Transport, was sowohl beim Einzeltransport als auch beim Massentransport von Vorteil ist Darüber hinaus kann bei einer vorteilhaften Ausgestaltung vorgesehen sein, dass die Austragvorrichtung über eine Schutzkappe verfügt, welche lediglich dann aufsetzbar ist, wenn die Austraghandhabe in ihrer Staustellung ist. Die Gefahr, dass ein Benutzer die Überführung der Austragvorrichtung in ihren deaktivierten Betriebszustand vergisst, ist dadurch vermindert.In a further development of the invention, the discharge handle is arranged in the deactivated operating state in a space-saving stowed position. In this stowage position, the discharge handle is preferably tight against the housing of the discharge device. A space-saving stowage position facilitates transport, which is advantageous both for individual transport and for mass transport. In addition, in an advantageous embodiment it can be provided that the discharge device has a protective cap which can only be placed when the discharge handle is in its stowed position. The risk that a user forgets the transfer of the discharge in its deactivated operating state is thereby reduced.
Bei einer Weiterbildung der Erfindung ist die Austraghandhabe im aktivierten Zustand nicht in die Staustellung bewegbar. Die axiale Wirkkopplung zwischen der Austraghandhabe und dem Träger ist zu diesem Zweck so ausgebildet, dass bei Bestehen dieser Wirkkopplung die Austraghandhabe sowohl im betätigten als auch im unbetätigten aktivierten Zustand die Staustellung nicht erreicht. Eine derartige Gestaltung gewährleistet, dass die Austragvorrichtung nicht versehentlich, beispielsweise durch Bewegung im Zusammenhang mit dem Transport der Austragvorrichtung auf dem deaktivierten Betriebzustand in den betätigten aktivierten Betriebzustand überführt wird. Eine solche ungewollte Überführung der Austragvorrichtung in den aktivierten Betriebszustand hätte zum einen bei der Montage Nachteile und zum anderen wäre ein betätigungs- und leckagefreier Transport nicht mehr gewährleistet.In a further development of the invention, the discharge handle in the activated state is not movable into the stowage position. The axial active coupling between the discharge handle and the carrier is designed for this purpose so that when this active coupling the discharge handle does not reach the stowed position both in the actuated and in the unactuated activated state. Such a design ensures that the discharge device is not accidentally transferred, for example by movement in connection with the transport of the discharge on the deactivated operating state in the actuated activated operating state. Such an unintentional transfer of the discharge in the activated operating state would have on the one hand in the assembly disadvantages and on the other hand would be an actuation and leak-free transport is no longer guaranteed.
Bei einer Weiterbildung der Erfindung ist der Betriebszustand durch eine Drehbewegung des Trägers um die Hauptachse steuerbar, wobei in mindestens einem ersten Winkelabschnitt die axiale Wirkverbindung zwischen dem Träger und der Austraghandhabe besteht und in mindestens einem zweiten Winkelabschnitt die axiale Wirkverbindung zwischen dem Träger und der Austraghandhabe unterbrochen ist. Bei dieser Ausgestaltung kann demnach eine Relativdrehung zwischen der Austraghandhabe und dem Träger genutzt werden, um den Betriebszustand festzulegen. Vorzugsweise wird zu diesem Zweck der Träger gegenüber dem Gehäuse mit Austraghandhabe verdreht. Diese Lösung stellt eine besonders einfache Möglichkeit dar, um durch einen einfachen Bewegungsablauf den Betriebszustand zu steuern. Der Träger weist zu diesem Zweck eine unterschiedliche Gestaltung in verschiedenen Winkelabschnitten bezogen auf die Hauptachse auf. Besonders vorteilhaft sind Gestaltungen, bei denen der erste und der zweite Winkelabschnitt gemeinsam einen Winkel von nicht über 90° einnehmen, so dass schon mit einer vergleichsweise geringen Bewegung der Betriebszustand gewechselt werden kann. Im ersten Winkelabschnitt besteht eine axiale Wirkverbindung, so dass eine Betätigung der Austraghandhabe eine Translationsbewegung des Trägers zur Folge hat, die wiederum über eine Bewegung Pumpspenders zu einem Austragvorgang führt. Im zweiten Winkelabschnitt ist diese axiale Wirkverbindung zwischen Träger und Austraghandhabe unterbrochen, wobei dies durch eine vollständige Entkopplung des Trägers von der Austraghandhabe oder aber durch eine Entkopplung lediglich im Hinblick auf die axiale Komponente realisiert sein kann.In a further development of the invention, the operating state is controllable by a rotational movement of the carrier about the main axis, wherein in at least a first angle section, the axial operative connection between the carrier and the discharge handle and interrupted in at least a second angle section, the axial operative connection between the carrier and the discharge handle is. In this embodiment Accordingly, a relative rotation between the discharge and the carrier can be used to determine the operating condition. Preferably, for this purpose, the carrier is rotated relative to the housing with discharge handle. This solution is a particularly simple way to control the operating state by a simple movement. The carrier has for this purpose a different design in different angle sections relative to the main axis. Particularly advantageous are designs in which the first and the second angle section together occupy an angle of not more than 90 °, so that even with a comparatively small movement of the operating state can be changed. In the first angle section there is an axial operative connection, so that an actuation of the discharge handle results in a translational movement of the carrier, which in turn leads to a discharge process via a movement of the pump dispenser. In the second angle section, this axial operative connection between carrier and discharge handle is interrupted, this being possible by a complete decoupling of the carrier from the discharge handle or else by a decoupling only with regard to the axial component.
Besonders bevorzugt sind Ausführungsformen, bei denen in einem dritten Winkelabschnitt eine axiale Sperrverbindung zwischen dem Träger und der Austraghandhabe besteht, durch die die Austraghandhabe in einer Sperrstellung gehalten wird. Diese Sperrstellung entspricht vorzugsweise der Staustellung der Austraghandhabe. Durch die Gestaltung des Trägers im Hinblick auf den dritten Winkelabschnitt kann gewährleistet werden, dass die Austraghandhabe im deaktivierten Betriebszustand in dieser Staustellung verbleibt, so dass die Austragvorrichtung eine vorteilhafte geringe Ausdehnung aufweist, und zudem auch vermieden wird, dass die Austraghandhabe in störender Art und Weise im entkoppelten Zustand frei beweglich ist.Particularly preferred embodiments are those in which in a third angle section an axial locking connection between the carrier and the discharge handle, by which the discharge handle is held in a blocking position. This locking position preferably corresponds to the stowed position of the discharge handle. The design of the carrier with respect to the third angle section can ensure that the discharge handle remains in this stowed position in the deactivated operating state, so that the discharge device has an advantageous low expansion, and also prevents the discharge handle from interfering with it is freely movable in the decoupled state.
Bei einer Weiterbildung der Erfindung weist der Träger einen Wirkverbindungsabschnitt zum Zusammenwirken mit der Austraghandhabe auf, wobei der Wirkverbindungsabschnitt zumindest eine sich radial erstreckende Ausnehmung aufweist, in die im aktivierten Betriebszustand ein mit der Austraghandhabe verbundener Führungsfortsatz ragt.In one development of the invention, the carrier has an operative connection section for interacting with the discharge handle, wherein the active connection section has at least one radially extending recess, into which, in the activated operating state, a guide extension connected to the discharge handle protrudes.
Der Führungsfortsatz ist dafür ausgebildet, im aktivierten Betriebszustand mittels der Austraghandhabe in Richtung des ersten gehäusefesten Anschlags bewegt zu werden, wobei zusammen mit dem Führungsfortsatz auch der Wirkverbindungsabschnitt des Trägers und damit der Träger in Richtung des ersten gehäusefesten Anschlags bewegt wird. Im einfachsten Fall ist die Ausnehmung als einfacher Freiraum unter einem sich vom Träger radial erstreckenden Vorsprung ausgestaltet. Bei einer solchen Ausgestaltung besteht die Wirkkopplung zwischen der Austraghandhabe und dem Träger darin, dass die Bewegung des Führungsfortsatzes der Austraghandhabe mittels einer Krafteinleitung in den Vorsprung eine entsprechende Bewegung des Trägers und eine damit einhergehende Pumpenbetätigung verursacht, während in Gegenrichtung keine entsprechende Wirkkopplung besteht. Bei einer anderen Ausgestaltung ist die Ausnehmung am Wirkverbindungsabschnitt des Trägers in beide Richtungen der Hauptachse geschlossen, so dass eine in beide Richtungen wirkende Zwangskopplung zwischen dem Träger und dem Führungsfortsatz der Austraghandhabe im aktivierten Betriebszustand besteht.The guide extension is adapted to be moved in the activated operating state by means of the discharge in the direction of the first housing fixed stop, which together with the guide extension and the active connection portion of the carrier and thus the carrier is moved in the direction of the first housing fixed stop. In the simplest case, the recess is designed as a simple free space under a projection extending radially from the carrier. In such an embodiment, the active coupling between the discharge handle and the carrier is that the movement of the guide extension of the discharge by means of a force in the projection causes a corresponding movement of the carrier and an associated pump actuation, while in the opposite direction no corresponding active coupling exists. In another embodiment, the recess is closed on the operative connection portion of the carrier in both directions of the main axis, so that there is a forced coupling acting in both directions between the carrier and the guide extension of the discharge in the activated operating state.
Bei einer besonders bevorzugten Ausführungsform der Austragvorrichtung weist der Wirkverbindungsabschnitt eine zumindest teilzylindrische Form auf, die sich in Richtung der Hauptachse erstreckt, wobei die Ausnehmung als Steuerkurve ausgebildet ist, die sich auf einer Mantelfläche des Wirkverbindungsabschnitts erstreckt. Die Steuerkurve ordnet jeder Drehstellung des Trägers in unbetätigter Lage und damit dessen Wirkverbindungsabschnitts eine korrespondierende Stellung der Austraghandhabe zu. Durch Verdrehen des Trägers und damit des Wirkverbindungsabschnitts wird festgelegt, wo auf der Steuerkurve sich der austraghandhabeseitige Führungsfortsatz befindet.In a particularly preferred embodiment of the discharge device, the active connection portion has an at least partially cylindrical shape which extends in the direction of the main axis, wherein the recess is formed as a control curve which extends on a lateral surface of the operative connection portion. The control cam assigns each rotational position of the carrier in the unactuated position and thus its Wirkverbindungsabschnitts a corresponding position of the discharge to. By rotating the carrier and thus the active connection section, it is determined where the discharge handle-side guide extension is located on the control curve.
Dabei ist die Steuerkurve vorzugsweise derart ausgestaltet, dass sie im ersten Winkelabschnitt einen ersten Steuerkurvenabschnitt aufweist, der sich auf der Außenfläche des Wirkverbindungsabschnitts in einer zur Hauptachse orthogonalen Ebene erstreckt und/oder im zweiten Winkelabschnitt einen zweiten Steuerkurvenabschnitt aufweist, der sich auf der Außenfläche des Wirkverbindungsabschnitts bezogen auf die Hauptasche axial und bezogen auf die Außenfläche des Kulissenabschnitts in Umfangsrichtung erstreckt und/oder im dritten Winkelabschnitt einen dritten Steuerkurvenabschnitt aufweist, der sich auf die Außenfläche des Wirkverbindungsabschnitts in einer zur Hauptachse orthogonalen Ebene erstreckt. Bei entsprechender Ausgestaltung ist dann, wenn sich der Führungsfortsatz im ersten oder im dritten Winkelabschnitt befindet, eine Zwangskopplung zwischen der Austraghandhabe und dem Träger gegeben. Im ersten Winkelabschnitt ist diese Zwangskopplung so geartet, dass einem Bewegungsbereich der Austraghandhabe ein Bewegungsbereich des Trägers zugeordnet ist, wobei dieser Bewegungsbereich des Trägers auf den Pumphub der Pumpe im Pumpspender und dessen Lage relativ zum ersten gehäusefesten Anschlag abgestimmt ist. Im dritten Winkelabschnitt ist die Zwangskopplung zwischen dem Träger und der Austraghandhabe vorzugsweise derart ausgebildet, dass eine Bewegung der Austraghandhabe nicht möglich ist Dies wird dadurch erreicht, dass der Träger an seiner dem ersten gehäusefesten Anschlag entgegengesetzten Endlage angeordnet ist, weiche vorzugsweise durch einen gehäusefesten Gegenanschlag definiert ist. In dieser Lage kann eine weitere Bewegung des Trägers weg vom ersten gehäusefesten Anschlag nicht erfolgen, so dass die in ihrer Staustellung befindliche Austraghandhabe gemeinsam mit dem in seiner Endlage befindlichen Träger ein stabiles System bilden, in dem eine Relativbewegung so lange nicht möglich ist, so lange der Führungsfortsatz sich im dritten Winkelabschnitt befindet. Die Steuerkurve ist im zweiten Steuerkurvenabschnitt vorzugsweise derart ausgebildet, dass sie den ersten Steuerkurvenabschnitt und den dritten Steuerkurvenabschnitt miteinander verbindet und sich zu diesem Zweck in etwa helixabschnittsförmig auf einer Außenfläche des Wirkverbindungsabschnitts erstreckt. Wenn der Führungsfortsatz der Austraghandhabe sich in diesem zweiten Steuerkurvenabschnitt befindet, führt eine Bewegung der Austraghandhabe lediglich zu einem Verdrehen des Trägers bzw. des Wirkverbindungsabschnitts, wobei es allerdings nicht zu einer axialen Verschiebung des Trägers kommt. Es ist also dann, wenn der Führungsfortsatz im zweiten Steuerkurvenabschnitt oder im dritten Steuerkurvenabschnitt angeordnet ist, nicht möglich, eine Lageveränderung des Trägers in axialer Richtung zu bewirken.In this case, the control cam is preferably configured such that it has in the first angle section a first control cam section which extends on the outer surface of the active connection section in a plane orthogonal to the main axis and / or in the second angular section has a second control section which extends on the outer surface of the operative connection section axially relative to the main pocket and extending in the circumferential direction relative to the outer surface of the gate section and / or in the third angular section having a third cam section extending on the outer surface of the operative connection section in a plane orthogonal to the main axis. With a corresponding embodiment, when the guide extension is in the first or in the third angle section, a forced coupling between the discharge handle and the carrier is provided. In the first angle section, this positive coupling is such that a movement range of the discharge handle is assigned a movement range of the carrier, this movement range of the carrier is tuned to the pump stroke of the pump in the pump dispenser and its position relative to the first housing-fixed stop. In the third angle section, the positive coupling between the carrier and the discharge handle is preferably designed such that movement of the discharge handle is not possible. This is achieved by arranging the carrier at its end position opposite the first housing-fixed stopper, which preferably is defined by a counterstay fixed to the housing is. In this position, a further movement of the carrier away from the first housing-fixed stop does not occur, so that the discharge handle located in its stowed position together with the carrier located in its end position form a stable system in which a relative movement is not possible as long as the guide extension is in the third angle section. The cam is preferably formed in the second cam portion so that it connects the first cam portion and the third cam portion together and extends for this purpose in approximately helix portion-shaped on an outer surface of the operative connection portion. If the guide extension of the discharge handle is located in this second cam section, a movement of the discharge handle only leads to a rotation of the carrier or of the active connection section, although there is no axial displacement of the carrier. It is therefore when the guide extension is arranged in the second cam section or in the third cam section, it is not possible to effect a change in position of the carrier in the axial direction.
Erfindungsgemäß ist die Austragvorrichtung mittels einer Aktivierungshandhabe zwischen dem aktivierten Betriebszustand und dem deaktivierten Betriebszustand umschaltbar. Eine solche Aktivierungshandhabe kann von einem Benutzer vor Verwendung der Austragvorrichtung genutzt werden, und die Austragvorrichtung in den aktivierten Betriebszustand zu überführen. Es handelt sich bei der Aktivierungshandhabe um eine zweite Handhabe neben der Austraghandhabe.According to the invention, the discharge device can be switched by means of an activation handle between the activated operating state and the deactivated operating state. Such an activation handle may be utilized by a user prior to using the dispenser, and to transfer the dispenser to the activated operating state. The activation handle is a second handle in addition to the discharge handle.
Besonders bevorzugt ist eine Aktivierungshandhabe, die drehbar ausgebildet ist und mit dem Träger drehgekoppelt wirkverbunden ist. Im einfachsten Fall kann die Aktivierungshandhabe Teil des Trägers oder mit diesem identisch sein, so dass dieser unmittelbar vom Bediener gehandhabt wird, um den Betriebszustand der Austragvorrichtung zu ändern. Denkbar ist jedoch auch eine Aktivierungshandhabe, die über eine Kupplung mit dem Träger wirkverbunden ist, wobei dies den Vorteil bietet, dass die axiale Bewegung des Trägers infolge einer Betätigung der Austraghandhabe nicht gleichzeitig eine Axialbewegung der Aktivierungshandhabe zur Folge hat.Particularly preferred is an activation handle which is designed to be rotatable and is operatively connected to the carrier in a rotationally coupled manner. In the simplest case, the activation handle can be part of the carrier or with be identical so that it is handled directly by the operator to change the operating state of the discharge. However, it is also conceivable an activation handle, which is operatively connected via a coupling with the carrier, which offers the advantage that the axial movement of the carrier due to an actuation of the discharge does not simultaneously axial movement of the activation handle result.
Bei einer besonders bevorzugten Weiterbildung ist die Aktivierungshandhabe mit dem Träger mittels einer Rutschkupplung verbunden. Hierdurch wird vermieden, dass die Aktivierungshandhabe zum Schaden des Trägers oder der Austraghandhabe über eine Sollstellung hinausgedreht werden kann. Gleichzeitig erlaubt es eine Rutschkupplung dem Bediener, die Aktivierungshandhabe zu betätigen, ohne auf eine Endlage Rücksicht nehmen zu müssen, da nach Erreichen des aktivierten bzw. des deaktivierten Betriebszustandes eine darüber hinausgehende bewegende Aktivierungshandhabe zu einem vorzugsweise wahrnehmbaren Durchrutschen der Rutschkupplung führt.In a particularly preferred embodiment, the activation handle is connected to the carrier by means of a slip clutch. This avoids that the activation handle to the damage of the carrier or the discharge handle can be rotated beyond a desired position. At the same time, a slip clutch allows the operator to actuate the activation handle without having to take account of an end position, since, after reaching the activated or deactivated operating state, a further moving activation handle leads to a preferably perceptible slippage of the slip clutch.
Bei einer besonders vorteilhaften Gestaltung der Rutschkupplung weist diese eine Verzahnung auf, deren Zähne zumindest zum Teil beim Überschreiten eines definierten Widerstandsdrehmoments so weit elastisch verformbar sind, dass sie aus dem Eingriff geraten. Dies stellt eine sehr preiswerte Form einer Rutschkupplung dar, die darüber hinaus noch den Vorteil bietet, dass am Erreichen des Rutschbereichs charakteristische Geräusche durch die abgleitenden Zähne der Verzahnung erzeugt werden, die dem Benutzer anzeigen, dass er den aktivierten bzw. den deaktivierten Betriebszustand erreicht hat.In a particularly advantageous design of the slip clutch, this has a toothing whose teeth are so far elastically deformable at least in part when a defined resistance torque is exceeded, that they fall out of engagement. This represents a very inexpensive form of a slip clutch, which also has the advantage that upon reaching the slip range characteristic noise generated by the sliding teeth of the teeth, indicating the user that he has reached the activated or deactivated operating state ,
Besonders bevorzugt ist eine Aktivierungshandhabe, die als Abschnitt des Außengehäuses ausgebildet ist, insbesondere als drehbarer Bodenabschnitt. Dies stellt eine technisch einfache Realisierung dar, die zudem im Hinblick auf Materialersparnis von Vorteil ist. Darüber hinaus ist die Gestaltung als drehbarer Bodenabschnitt deshalb von Vorteil, da eine solche Aktivierungshandhabe kaum mit einer üblicherweise hebelartig ausgebildeten Austraghandhabe verwechselt werden kann, was die Bedienung für den Endverbraucher erleichtert.Particularly preferred is an activation handle, which is designed as a section of the outer housing, in particular as a rotatable bottom portion. This represents a technically simple realization that Moreover, in terms of material savings is beneficial. In addition, the design as a rotatable bottom portion is advantageous because such an activation handle can hardly be confused with a usually lever-like discharge handle, which facilitates the operation for the end user.
Bei einer weiteren bevorzugten Weiterbildung weist die Austragvorrichtung eine Schutzkappe auf, die vorzugsweise in einem Funktionszustand die Überführung der Austragvorrichtung in den aktivierten Betriebszustand verhindert.In a further preferred development, the discharge device has a protective cap, which preferably prevents the transfer of the discharge device into the activated operating state in a functional state.
In diesem Funktionszustand, in dem die Schutzkappe auf die Austragvorrichtung aufgesetzt ist, umgreift sie vorzugsweise einen Bereich, in dem die Austraghandhabe vorgesehen ist, wobei dies erfordert, dass die Austraghandhabe sich im Stauzustand befindet. Diese Gestaltung der Schutzkappe führt zum einem dazu, dass eine versehentliche Überführung der Austragvorrichtung in den aktivierten Betriebszustand nicht versehentlich bei aufgesetzter Schutzkappe möglich ist. Zum anderen gewährleistet es darüber hinaus, dass ein Benutzer veranlasst ist, die Austragvorrichtung nach Gebrauch wieder in den deaktivierten Betriebszustand zu überführen, damit er die Schutzkappe wieder auf die Austragvorrichtung aufsetzen kann.In this functional state, in which the protective cap is placed on the discharge device, it preferably surrounds a region in which the discharge handle is provided, which requires that the discharge handle is in the jam state. This design of the protective cap leads to the fact that an accidental transfer of the discharge in the activated operating state is not accidentally possible with attached protective cap. On the other hand, it also ensures that a user is prompted to return the discharge after use in the deactivated mode, so that he can put the cap back on the discharge.

Die Austragvorrichtung weist insgesamt vier Baugruppen 10, 30, 50, 70 auf, die im Betrieb jeweils zueinander in verschiedener Art und Weise relativbeweglich und in sich jeweils weitgehend unbeweglich sind. Die erste Baugruppe 10 besteht aus einem Außengehäuse 12 sowie einem in das Außengehäuse im Bereich einer Austragöffnung 12a fest eingesetzten Füllstück 14. Das Füllstück 14 erstreckt sich von einem durch das Gehäuse gebildeten Applikator 12d entlang einer Richtung einer Hauptachse 2 der Austragvorrichtung in einen vom Gehäuse 12 umgebenen Innenraum 16. Die zweite Baugruppe 30 umfasst einen Träger 32, der als getrennte Bauteile einen oberen Trägerabschnitt 34 und einen unteren Trägerabschnitt 36 aufweist. Die Trägerabschnitte 34, 36 umgeben einen Freiraum 38, in den ein Pumpspender 40 eingesetzt ist. Dieser Pumpspender 40 entspricht einem handelsüblichen Pumpspender und umfasst einen in etwa zylindrischen Medienspeicher 42, auf den ein Pumpsystem 44 mittels einer Schnappverbindung 46 befestigt ist. Bei dem Pumpsystem 44 handelt es sich um ein gängiges Pumpsystem, welches über eine Relativverschiebung eines Austragrohrs 44a relativ zum Medienspeicher 42 betätigt wird. Das Austragrohr 44a erstreckt sich entlang der Hauptachse 2 bis in das Füllstück 14 hinein, wobei der obere Trägerabschnitt 34 zu diesem Zweck eine zentrische Durchbrechung 34a aufweist. Der Pumpspender 40 kann durch eine als Funktionsabschnitt 36b agierende Bodenfläche des unteren Trägerabschnitts in Richtung der Austragöffnung 12a gedrückt werden.The discharge device has a total of four
Der obere Trägerabschnitt 34 ist mit dem unteren Trägerabschnitt 36 über Rastmittel 34f, 36a verbunden. Auf Seiten des unteren Trägerabschnitts 36 bestehen die Rastmittel 36a in einer Rastleiter 36a, die sich umlaufend am oberen Ende des becherförmigen unteren Trägerabschnitts 36 erstrecken. Auf Seiten des oberen Trägerabschnitts 34 umfassen die Rastmittel eine Reihe von Rastzungen 34f. Die Rastmittel 34f, 36a erlauben durch die Ausgestaltung des Rastmittels 36a als umlaufende Rastleiter und eine besondere Gestaltung der Rastzungen 34f bezüglich ihrer Anordnung, die im Folgenden noch erläutert wird, eine Vielzahl verschiedener Raststellungen, so dass die Relativlage des oberen Trägerabschnitts 34 zum unteren Trägerabschnitt 36 in einer Vielzahl verschiedener Stellungen fixierbar ist.The
Die Trägerbaugruppe 30 ist gegenüber der Gehäusebaugruppe 10 in zweierlei Weise beweglich. Zum einen kann die Trägerbaugruppe 30 im Wesentlichen in ihrer Gesamtheit entlang der Hauptachse 2 in Richtung des Füllstücks 14 verschoben werden. Zum anderen kann die Trägerbaugruppe 30 um die Hauptachse 2 herum relativ zur Gehäusebaugruppe 10 verdreht werden. Beide Freiheitsgrade und ihre Kopplung werden im Weiteren noch erläutert.The
Die dritte Baugruppe 50 ist die Baugruppe einer Austraghandhabe 52, die als etwa L-förmiger schwenkbarer Hebel ausgebildet ist. Ein erster Schenkel 52c des einstückigen Hebels 52 erstreckt sich in das Gehäuse 12 hinein, während ein zweiter Schenkel 52b sich in etwa parallel zur Hauptachse 2 im Zustand der
Die vierte Baugruppe 70 ist die Baugruppe der Aktivierungshandhabe 72. Die Aktivierungshandhabe ist an der der Austragöffnung 12a abgewandten Seite des Gehäuses 12 vorgesehen und in etwa zylindrisch und becherförmig geformt. An einer Mantelfläche 72a ist ein umlaufender Führungsring 72b vorgesehen, der in einer Nut 12c des Gehäuses 12 aufgenommen ist. Das Gehäuse 12 und die Aktivierungshandhabe 72 bilden dabei eine Spielpassung, so dass die Aktivierungshandhabe 72 um die Hauptachse 2 relativ zum Gehäuse drehbar ausgebildet ist. Dies stellt gleichzeitig den einzigen Freiheitsgrad der Aktivierungshandhabe 72 in Bezug auf das Gehäuse 12 im Betrieb dar. An einem oberen Rand 72c weist die Aktivierungshandhabe 72 eine Innenverzahnung 72d auf. Diese ist im Zusammenwirken mit einer Außenverzahnung 34e am ersten Trägerabschnitt 34 des Trägers 32 ausgebildet. Während die Innenverzahnung 72d ganzflächig einen Abschnitt der Innenseite Aktivierungshandhabe 72 überdeckt, ist die Verzahnung 34e am ersten Trägerabschnitt 34 auf insgesamt nur drei auf den Umfang verteilte Zähne 34e beschränkt.The

Die dargestellte Austragvorrichtung verbindet eine sehr praktische Handhabung durch getrennte Aktivierung und Betätigung mit einer besonders vorteilhaften Montierbarkeit, durch die Toleranzen in den Bauteilen ausgeglichen werden, sowie mit einer ebenfalls vorteilhaften Pumpensicherung in Form des zweiten gehäusefesten Anschlags, der eine Überbeanspruchung des Pumpsystems des Pumpspenders verhindert.The discharge device shown combines a very practical handling by separate activation and actuation with a particularly advantageous mountability, are compensated by the tolerances in the components, and with a likewise advantageous pump protection in the form of the second housing fixed stop, which prevents overuse of the pumping system of the pump dispenser.
