Definitions
- the invention relates to a discharge device for media according to the preamble of claim 1.
- the spray device disclosed therein comprises a cylindrical housing in which a pump dispenser is arranged.
- This pump dispenser includes a media reservoir and a pump which can be activated by axially compressing the pump dispenser. This axial compression is achieved indirectly via a handle, which is integrally connected to a carrier. Upon actuation of this handle, the pump dispenser is pressed in its entirety against a housing fixed stop, whereby the pump is compressed and thus the medium is conveyed from the pump dispenser, which is then further promoted to a discharge opening of the spray device and discharged from this.
- discharge devices are considered in many ways to be improved. Due to manufacturing tolerances in the housing-fixed stop as well as the pump provided in the pump dispenser, the operating range in which the discharge handle has to be moved for actuation in order to produce a discharge process, scatters to a great extent. This may result in a complete pump stroke beyond the discharge handle being unavailable or actuation beyond the end of the pump stroke. Furthermore, it is considered to be disadvantageous that the discharge handle protrudes in the unactuated state far from the housing of the discharge, so that the packing volume of such a discharge device is relatively large and there is a risk that accidentally in the transport handling of the discharge medium is discharged.
- EP 1 616 629 A1 disclose generic discharge devices.
- WO 02/30504 A1 and WO 01/03851 disclose generic discharge devices.
- a dispensing device in which a pump dispenser relative to an actuating handle with respect to its position in the direction of actuation by a thread is adjustable, so that different pump dispenser with the discharge device can be used.
- 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 is an actuation 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 may also occupy a fixed position in the housing while only the pump is moved by the carrier during a dispensing operation.
- an area in the movement sequence of the discharge handle can be determined, in which the actuation of the discharge handle causes actuation of the pump dispenser.
- an actuation of the discharge handle is not sufficient to carry out the complete pumping stroke or else it can still be moved after reaching the full pumping stroke.
- the adjustment also allows the use of different types of pump dispenser, as by adjusting the adjustment means the position of the functional section relative to the first housing-side stop in the operation of the discharge handle can be influenced.
- the adjusting means is preferably arranged within the housing or in another way such that it is not accessible during normal operation of the discharge device. This prevents that after adjusting the adjusting means in the course of a production and / or assembly process, a disadvantageous adjustment is made.
- adjusting means which are provided between the handle and the carrier or on a multi-part carrier between carrier sections themselves.
- the adjustment means is axially stepped adjustable. Furthermore, the adjustment means according to the invention is designed as a latching means which are formed for latching connections in a plurality of different locking positions, wherein the locking positions differ from each other by the axial position of the functional portion relative to the discharge or the first support portion.
- Such locking means are particularly advantageous in terms of their stability and ease of installation. They can be brought in a simple manner by applying a defined assembly force in their desired position.
- the carrier has at least two carrier sections, wherein a first carrier section is forcibly guided by the discharge handle at least during actuation of the discharge handle, a second carrier section comprises the functional section of the carrier and the position of the carrier sections is adjustable relative to one another by means of the adjusting means.
- the movement sequence of the first support section is always the same as a function of the movement sequence of the discharge handle and can not be adjusted by the adjustment means.
- the first carrier section can be integrally connected to the discharge handle.
- a particularly simple embodiment can be achieved by a pivotable discharge handle, wherein on the discharge handle an integrally formed Hebelabschriitt is provided which engages under an integrally on the support portion radially extending extension.
- the adjusting means is provided between the two support sections and structurally easy to implement.
- the execution of the first and the second support portion offers as a simple design as in approximately cylindrical or cup-like components, which are connected to each other by a thread.
- the adjusting means can be adjusted.
- a second fixed housing stop is provided, whose interaction with the discharge handle or the first support portion is provided.
- This second housing-fixed stop thus determines indirectly or directly, to what extent the discharge handle can be actuated. Confirmation beyond this is prevented by the second housing-fixed stop.
- This second housing-fixed stop allows a particularly advantageous adjustment of the adjusting means, since it allows to adjust the adjusting means, while the discharge handle or the first support portion abut the second housing-fixed stop. If in this end position of the discharge handle or the first support portion, the adjusting means is adjusted so that the functional surface of the carrier is spaced relative to the first housing fixed stop so that the pump dispenser is in an actuated state, so as to ensure that in a subsequent Operation in operation of the effective pump stroke of the pump dispenser is exactly completed when the discharge handle or the first support portion comes to rest on the second housing-fixed stop.
- the step size of the axial graduation is preferably less than one millimeter, more preferably less than 0.6 mm, in particular less than 0.3 mm.
- the advantage of axially stepped and preferably positively acting adjustment means is that they have a high security against an unwanted provision depending on the design.
- the latching means comprise a plurality of partial latching means, the respective latching positions differ at least partially from each other. This provides the advantage that a bessonders fine division and thus particularly small increments can be achieved.
- latching means comprising at least one latching conductor with latching steps and the at least one latching conductor opposite two latching noses, which are designed to cooperate with the latching conductor.
- the latching lugs are arranged offset slightly relative to one another with respect to the extension direction of the latching conductor transversely to the latching steps, preferably offset by half the distance between the latching steps of the latching conductors.
- the latching conductor can be formed, for example, circumferentially on an outer side of the second carrier section, while the latching lugs are provided on an inner side of the first carrier section surrounding the second carrier section.
- a spacer is inserted between the functional section of the carrier and the pump dispenser.
- the use of such a spacer results in that a second functional section is formed by the spacer, which takes over the function of the first functional section with regard to the introduction of force into the pump dispenser.
- the spacer itself rests on the first functional section.
- the use of such a spacer allows the use of the same discharge device with different pump dispensers, which may differ in particular with respect to the size of their media storage. Although this flexibility can also be achieved by means of a corresponding design of the adjustment means, the adjustment means can be made substantially smaller in the use of spacers, since they then serve not primarily to adapt to different pump dispenser sizes but only to compensate for component tolerances.
- the functional section is arranged such that the introduction of force takes place through the functional section on the side of the pump dispenser facing away from the first housing-fixed stop.
- the functional portion of a discharge would attack according to this development on the bottom of the bottle.
- the advantage of an embodiment according to this development is in particular that the pump dispenser is compressed by the actuating force in each case in its entirety, so that a special tightness is achieved.
- the adjustment means are of great advantage, as they can be compensated by the tolerances in the pump dispenser between the bottle bottom and the pumping system of the pump dispenser.
- the carrier or the first carrier section has a preferably funnel-shaped centering aid and / or guide aid for connecting to a housing-fixed discharge channel on a side facing the first housing-fixed stop.
- Such a design of the carrier is particularly advantageous in discharge devices in which the carrier is inserted in the direction of the main axis in the housing.
- the correct guidance of the carrier is considerable so that a connection of the discharge channel is achieved with the pump dispenser.
- such a centering can also serve as Schwarzshüfe by determining the position of the carrier during the axial movement during operation.
- 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 it does not obstruct actuation of the pump dispenser, is displaceably arranged, wherein preferably the centering cone is slidably mounted on a dispensing tube, which forms the first housing-fixed stop and / or in which the receiving recess is formed.
- 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.
- 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.
- 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 in the connection areas a positive connection of the Housing shells is provided, by which a displacement of the housing shells against each other is prevented.
- the discharge handle for discharge handling is formed substantially transversely to the main axis and connected to the carrier via at least one separate transmission element.
- the translation element 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 the actuation of the discharge.
- 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.
- An actuation of the discharge handle acts via a contact directly on the transmission element, which in turn can be mounted either pivotable or linearly movable.
- this translation element then acts on the carrier and moves it along the main axis to the first housing-fixed stop.
- this translation element acts on the carrier and moves it along the main axis to the first housing-fixed stop.
- the discharge handle is designed as a first lever, which is pivotable about a pivot axis, which is provided on the side opposite the discharge opening of the discharge.
- the discharge handle can be moved by means of the thumb of the hand, which embraces the discharge handle.
- the discharge handle is moving and the thumb approximately parallel to each other, which is ergonomically advantageous because the force can be applied to the lever not only on the foremost phalanx of the thumb, but over the entire length of the thumb.
- the invention further comprises a method for mounting a pump dispenser in a discharge device provided for receiving a pump dispenser with a first housing fixed stop, wherein the pump dispenser is actuated by compression in the direction of a main axis, wherein the method is characterized in that the pump dispenser inserted into the discharge is and by means of an adjusting means an adjustment of the position of the pump dispenser in a compressed state of the pump dispenser relative to the position of the first housing-fixed stop.
- the actuation of the dispensing device is accompanied by a movement of a portion of the pump dispenser which is thereby displaced in the direction of the first housing-fixed abutment, so that this first section of the pump dispenser faces a second section of the pump dispenser comes to rest in the housing fixed stop, is relatively moved, which has an operation of the pump pump side pump provided.
- the adjustment allow it to compensate for various manufacturing and assembly tolerances within the discharge and in particular within the pump dispenser by a permanent adjustment by means of the adjustment, so that the pump dispenser is located after the adjustment relative to the first housing-fixed stop in a defined position. This leads to a high reproducibility of the behavior of the discharge when actuated. Identical discharge devices are despite their different component tolerances respect. Their discharge behavior for the user indistinguishable.
- the pump In the compressed state in which the adjustment takes place, the pump is located in the pump dispenser at the end of its pumping stroke. If in this case
- the adjustment takes place to the effect that the pump dispenser is in the actuated state when the dispensing handle or a part operatively connected to it reaches an associated second stop.
- the discharge handle or the component operatively connected to it reaches the second associated stop so that actuation of the discharge handle beyond this state can not take place.
- the pump provided in the pump dispenser is thereby protected against overloading, because an exceeding operation of the discharge handle is prevented by the second stop.

- the protective cap 90 is already removed in this state and the discharge device is still in the deactivated operating state, which results from the fact that the guide extensions 52e are located in the second control cam sections 34h of the control cams 34c.
- An actuation of the discharge handle 52 is possible in this state only insofar as that the discharge handle 52 manually related to the perspective of the Fig. 1 can be swung clockwise, this has no effect on the position of the carrier 32 in the direction of the main axis 2, but only causes a rotation of the carrier 32 about the main axis 2.
- the activation handle 72 is rotated in the direction of rotation 4. This is in Fig.
- Fig. 8 shows the operation of the discharge handle 52 and the resulting discharge device.
- the discharge pipe 44a of the pump dispenser 40 is pressed during actuation against the first housing-fixed stop 14b of the filler 14 and thereby displaced relative to the media reservoir 42 of the pump dispenser 40 against a spring force of a return spring of the pumping system 44.
- This leads to a pumping process which ends at the moment at the moment in which the operative connection portion 34 d of the upper support portion 34 abuts against the second housing-fixed stop 12 d of the housing 12.
- the type of assembly described above ensures that, irrespective of the specific actuating force required, which is specific for the pump dispenser 40 used, the pumping stroke of the pumping system of the pump dispenser 40 is also passed through at this moment, so that the desired quantity of the medium was discharged. After releasing the actuating force the discharge device is returned to its original position by the restoring force of the spring of the pumping system.
- 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.
- the Fig. 9 to 12 show a second embodiment of a discharge device according to the invention.
- the basic mode of operation is similar to the mode of operation of the first embodiment.
- this discharge device is also based on the fact that a pump dispenser 140 is displaced axially relative to a first stop 114b which is fixed to the housing by means of a discharge handle 152.
- 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 be able to compensate for component tolerances of the pump dispenser 140 and of the components of the discharge device.
- the assembly goes in a similar manner as in the first embodiment of Fig. 1 to 8 vonstatten.
- the inserted support 132 consisting of an upper support portion 134 and a lower support portion 136, is urged toward the discharge opening 122a until an upper end 132a of the support reaches a second fixed housing 112d stop.
- the carrier 132 is compressed by means of the latching means 134f, 136a to such an extent that the pumping system of the pump dispenser 140 is pressed in by pushing in a discharge tube 144a of the pump Pump dispenser 140 passes in its actuated stroke end position, while the discharge tube 144 a rests against the first housing-fixed stop 114 a.
- 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. 14 shown
- the final state of the assembly corresponds to the actuated state which is in Fig. 11 is shown.
- Fig. 10 shows the unactuated state after assembly.
- lifting of the carrier 132 can be achieved by the actuation of the discharge handle 152 by means of the transmission lever 160.
- 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. 11 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. 11 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
- the housing 12 in the embodiment of the Fig. 1 to 8 is formed as a largely one-piece housing into which the support assembly 30 is inserted axially
- the housing 112 of the second embodiment of the discharge device according to the invention is constructed differently.
- the housing 112 of the second embodiment of the discharge device according to the invention 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 Sowandungsabêten 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, in the region of the applicator 122, firmly attaches the two housing shells 118, 119 to one another.
- the joining ring 121 has a sealing portion 121a, which bears sealingly against the outer wall of the applicator component 122.
- 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.
- 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.
- 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.
- the second major difference relates to the presence of a centering cone 192.
- the centering cone 192 is slid onto the housing 112 at the lower end of the filler 114 before and during assembly of the carrier 130. This condition is in Fig. 9 represented by.
- 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.
- 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 reached when an upper end 132a of the carrier 132 arrives at a second housing-fixed stop 112d. The centering cone thereby enters an area in which it is not disturbing for the further operation of the discharge device.
- This end position of the centering cone 192 is the Fig. 10 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. 11 , corresponds, the centering cone 192 does not affect the operation in operation.
- the third significant difference between the second embodiment of a discharge device according to the invention according to the Fig. 9 to 11 compared to the first embodiment of the Fig. 1 to 8 lies in the design and the storage of the discharge handle 152 and in the presence of the transmission lever 160. While in the first embodiment of the Fig. 1 to 8 a largely linear relationship between the deflection of the Austraghandhabe 52 and the corresponding deflection of the carrier 32 is, in the actuating mechanism of the second embodiment of the Fig. 9 to 11 a more complex operating mechanism is provided. This includes the actuating lever 152, the transmission lever 160 and the carrier 132. Like the Fig.
- 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.
- the design with two levers, an actuating lever 152 and a transmission lever 160 has further advantages.
- the use of two levers 152, 160 makes it possible to provide the pivot axis 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. This is advantageous from an ergonomic point of view.
- the operating lever 152 and the transmission lever 160 are also in two perspectives Fig. 13 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, a recess 160b is provided on the transmission lever 160 between two contact tongues 160a. The contact tongues 160a engage in the recesses between the ribs 152i, 152j, 152k, while at the same time the middle rib 152j 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.
- 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.

Abstract
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 in Hinblick auf die Erfindung relevante Austragvorrichtung ist beispielsweise aus der in
Die zum Stand der Technik bekannten Austragvorrichtungen werden in vielerlei Hinsicht als verbesserungswürdig angesehen. Aufgrund von Fertigungstoleranzen beim gehäusefesten Anschlag sowie bei der im Pumpspender vorgesehenen Pumpe streut der Betätigungsbereich, in dem die Austraghandhabe zur Betätigung bewegt werden muss, um einen Austragvorgang hervorzurufen, in starkem Maße. Dies kann dazu führen, dass ein vollständiger Pumpenhub über die Austraghandhabe nicht erreichbar ist oder eine Betätigung über das Ende des Pumpenhubs hinweg möglich ist. Weiterhin wird als nachteilig angesehen, dass die Austraghandhabe im unbetätigten Zustand weit vom Gehäuse der Austragvorrichtung abragt, so dass das Packvolumen einer solchen Austragvorrichtung vergleichsweise groß ist und die Gefahr besteht, dass versehentlich bei der Transporthandhabung der Austragvorrichtung Medium ausgetragen wird. Weiterhin wird als nachteilig angesehen, dass die Montage derartiger Austragvorrichtungen in der Regel durch ein koaxiales Zusammenstecken in einer Haupterstreckungsrichtung der Austragvorrichtung erfolgen muss, was zu konstruktiven Limitationen führt, da beispielsweise Hinterschneidungen vermieden werden müssen. Es wird weiterhin die im Stand der Technik übliche Anordnung der Austraghandhabe als nachteilig angesehen, bei der eine Betätigung der Austraghandhabe mittels des Daumens einer Hand aufgrund der sich gegenüberliegenden Schwenkachsen des Daumens und der Handhabe nicht in ergonomischer Art und Weise möglich ist.The known in the art discharge devices are considered in many ways to be improved. Due to manufacturing tolerances in the housing-fixed stop as well as the pump provided in the pump dispenser, the operating range in which the discharge handle has to be moved for actuation in order to produce a discharge process, scatters to a great extent. This may result in a complete pump stroke beyond the discharge handle being unavailable or actuation beyond the end of the pump stroke. Furthermore, it is considered to be disadvantageous that the discharge handle protrudes in the unactuated state far from the housing of the discharge, so that the packing volume of such a discharge device is relatively large and there is a risk that accidentally in the transport handling of the discharge medium is discharged. Furthermore, it is considered to be disadvantageous that the assembly of such discharge devices usually has to be done by a coaxial mating in a main extension direction of the discharge, resulting in constructive limitations, since, for example, undercuts must be avoided. Furthermore, the arrangement of the dispensing handle which is customary in the prior art is considered to be disadvantageous, in which an actuation of the dispensing handle by means of the thumb of a hand is not possible in an ergonomic manner due to the opposing pivot axes of the thumb and the handle.
Aus der
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 erreicht.This is achieved by a discharge device according to claim 1 according to the invention.
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 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 is an actuation 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 may also occupy a fixed position in the housing while only the pump is moved by the carrier during a dispensing operation.
Durch die Gestaltung mit einem Verstellmittel, mit dem der Funktionsabschnitt des Trägers, der zum Zwecke der Bewegung auf dem Pumpspender eine in Richtung des ersten gehäusefesten Anschlags wirkende Kraft ausübt, bezüglich seiner Relativlage zur Austraghandhabe verstellbar ist, kann eingestellt werden, in welcher Lage sich der Pumpspender bei einer definierten Stellung der Austraghandhabe befindet. Dies gestattet es, Toleranzen, die beispielsweise im Hinblick auf die Lage des Anschlags relativ zum Gehäuse, auf den wirksamen Pumphub relativ vom Pumpspender und auf ein Auslassrohr des Pumpspenders und dessen Länge bestehen, wirksam zu kompensieren. Hiermit wird erreicht, dass trotz der genannten und weiterer Fertigungstoleranzen bezüglich der einzelnen Bauteile ein Austragvorgang stets bei der gleichen Stellung der Austraghandhabe beginnt und/oder bei der gleichen Stellung der Austraghandhabe endet. Es kann demnach ein Bereich im Bewegungsablauf der Austraghandhabe festgelegt werden, in welchem die Betätigung der Austraghandhabe eine Betätigung des Pumpspenders bewirkt. Insbesondere ist vermeidbar, dass eine Betätigung der Austraghandhabe nicht ausreicht, um den vollständigen Pumphub durchzuführen oder aber noch nach Erreichen des vollen Pumphubs weiter bewegbar ist. Das Verstellmittel erlaubt darüber hinaus die Verwendung verschieden gearteter Pumpspender, da durch ein Verstellen der Verstellmittel die Lage des Funktionsabschnitts relativ zum ersten gehäuseseitigen Anschlag bei der Betätigung der Austraghandhabe beeinflusst werden kann.By the design with an adjusting means, with which the functional portion of the carrier, which exerts a force acting in the direction of the first housing-fixed stop force for the purpose of movement on the pump dispenser, with respect to its relative position to the discharge handle is adjustable, can be adjusted in which position of the Pump dispenser is located at a defined position of the discharge handle. This makes it possible to effectively compensate for tolerances that exist, for example, on the position of the stop relative to the housing, on the effective pump stroke, relative to the pump dispenser, and on an outlet tube of the pump dispenser and its length. This ensures that, despite the above-mentioned and further manufacturing tolerances with respect to the individual components, a discharge process always begins at the same position of the discharge handle and / or ends at the same position of the discharge handle. Accordingly, an area in the movement sequence of the discharge handle can be determined, in which the actuation of the discharge handle causes actuation of the pump dispenser. In particular, it is avoidable that an actuation of the discharge handle is not sufficient to carry out the complete pumping stroke or else it can still be moved after reaching the full pumping stroke. The adjustment also allows the use of different types of pump dispenser, as by adjusting the adjustment means the position of the functional section relative to the first housing-side stop in the operation of the discharge handle can be influenced.
Das Verstellmittel ist vorzugsweise innerhalb des Gehäuses oder auf andere Art und Weise derart angeordnet, dass es im bestimmungsgemäßen Betrieb der Austragvorrichtung nicht zugänglich ist. SO wird verhindert, dass nach Justieren des Verstellmittels im Zuge eines Produktions- und/oder Montagevorgang ein nachteiliges Verstellen vorgenommen wird.The adjusting means is preferably arranged within the housing or in another way such that it is not accessible during normal operation of the discharge device. This prevents that after adjusting the adjusting means in the course of a production and / or assembly process, a disadvantageous adjustment is made.
Die tatsächlich Anordnung und Ausgestaltung des Verstellmittels ist in vielen verschiedenen Ausgestaltungen denkbar. Insbesondere bevorzugt sind Verstellmittel, die zwischen der Handhabe und dem Träger oder an einem mehrteiligen Träger zwischen Trägerabschnitten selbst vorgesehen sind.The actual arrangement and configuration of the adjusting means is conceivable in many different embodiments. Particularly preferred are adjusting means, which are provided between the handle and the carrier or on a multi-part carrier between carrier sections themselves.
Erfindungsgemäß ist das Verstellmittel axial gestuft einstellbar. Weiterhin ist erfindungsgemäß das Verstellmittel als Rastmittel ausgebildet, die für Rastverbindungen in einer Mehrzahl verschiedener Raststellungen ausgebildet sind, wobei die Raststellungen sich voneinander durch die axiale Lage des Funktionsabschnitts relativ zur Austraghandhabe oder dem ersten Trägerabschnitt unterscheiden. Derartige Rastmittel sind insbesondere im Hinblick auf ihre Stabilität und die einfache Montagemöglichkeit vorteilhaft. Sie können in einfache Art und Weise durch Aufbringen einer definierten Montagekraft in ihre Soll-Lage gebracht werden.According to the adjustment means is axially stepped adjustable. Furthermore, the adjustment means according to the invention is designed as a latching means which are formed for latching connections in a plurality of different locking positions, wherein the locking positions differ from each other by the axial position of the functional portion relative to the discharge or the first support portion. Such locking means are particularly advantageous in terms of their stability and ease of installation. They can be brought in a simple manner by applying a defined assembly force in their desired position.
Bei einer Weiterbildung der Erfindung weist der Träger mindestens zwei Trägerabschnitte auf, wobei ein erster Trägerabschnitt zumindest während einer Betätigung der Austraghandhabe durch die Austraghandhabe zwangsgeführt ist, ein zweiter Trägerabschnitt den Funktionsabschnitt des Trägers umfasst und die Lage der Trägerabschnitte zueinander mittels des Verstellmittels verstellbar ist.In a further development of the invention, the carrier has at least two carrier sections, wherein a first carrier section is forcibly guided by the discharge handle at least during actuation of the discharge handle, a second carrier section comprises the functional section of the carrier and the position of the carrier sections is adjustable relative to one another by means of the adjusting means.
Bei einer Austragvorrichtung gemäß dieser Weiterbildung ist der Bewegungsablauf des ersten Trägerabschnitts in Abhängigkeit des Bewegungsablaufs der Austraghandhabe stets gleich und durch die Verstellmittel nicht einstellbar. Dies führt zu der Möglichkeit sehr einfacher Ausgestaltungen der Wirkverbindung zwischen der Betätigungshabe und dem ersten Trägerabschnitt. So kann der erste Trägerabschnitt im einfachsten Falle einstückig mit der Austraghandhabe verbunden sein. Ebenfalls eine besonders einfache Ausgestaltung ist durch eine schwenkbewegliche Austraghandhabe erzielbar, wobei an der Austraghandhabe ein einstückig angeformter Hebelabschriitt vorgesehen ist, der unter einen einstückig am Trägerabschnitt sich radial erstreckenden Fortsatz greift. Das Verstellmittel ist zwischen den beiden Trägerabschnitten vorgesehen und konstruktiv einfach realisierbar. Hier bietet sich als einfache Gestaltung beispielsweise die Ausführung des ersten und des zweiten Trägerabschnitts als in etwa zylindrische oder becherartige Bauteile an, die miteinander durch ein Gewinde verbunden sind. So kann durch einfaches Verdrehen des zweiten Trägerabschnitts relativ zum ersten Trägerabschnitt die Einstellung des Verstellmittels erfolgen.In a discharge device according to this development, the movement sequence of the first support section is always the same as a function of the movement sequence of the discharge handle and can not be adjusted by the adjustment means. This leads to the possibility of very simple embodiments of the operative connection between the actuating member and the first support portion. Thus, in the simplest case, the first carrier section can be integrally connected to the discharge handle. Also, a particularly simple embodiment can be achieved by a pivotable discharge handle, wherein on the discharge handle an integrally formed Hebelabschriitt is provided which engages under an integrally on the support portion radially extending extension. The adjusting means is provided between the two support sections and structurally easy to implement. Here, for example, the execution of the first and the second support portion offers as a simple design as in approximately cylindrical or cup-like components, which are connected to each other by a thread. Thus, by simply rotating the second carrier section relative to the first carrier section, the adjusting means can be adjusted.
Bei einer Weiterbildung der Erfindung ist ein zweiter gehäusefester Anschlag vorgesehen, dessen Zusammenwirken mit der Austraghandhabe oder dem ersten Trägerabschnitt vorgesehen ist.In a further development of the invention, a second fixed housing stop is provided, whose interaction with the discharge handle or the first support portion is provided.
Dieser zweite gehäusefeste Anschlag bestimmt demnach mittelbar oder unmittelbar, wieweit die Austraghandhabe betätigt werden kann. Eine Bestätigung darüber hinaus wird durch den zweiten gehäusefesten Anschlag verhindert. Dieser zweite gehäusefeste Anschlag erlaubt eine besonders vorteilhafte Einstellung der Verstellmittels, da er es gestattet, das Verstellmittel einzustellen, während die Austraghandhabe bzw. der erste Trägerabschnitt am zweiten gehäusefesten Anschlag anliegen. Wenn in dieser Endlage der Austraghandhabe oder des ersten Trägerabschnitts das Verstellmittel so eingestellt wird, dass die Funktionsfläche des Trägers relativ zum ersten gehäusefesten Anschlag derart beabstandet ist, dass der Pumpspender sich in einem betätigten Zustand befindet, so ist damit gewährleistet, dass bei einer nachfolgenden Betätigung im Betrieb der wirksame Pumphub des Pumpspenders genau dann beendet ist, wenn die Austraghandhabe bzw. der erste Trägerabschnitt am zweiten gehäusefesten Anschlag zum Anliegen kommt. Dies stellt einen wirksamen Schutz der Pumpe gegen eine Überbeanspruchung dar, da die Pumpe über ihren bestimmungsgemäßen Pumphub hinaus nicht zusammengedrückt werden kann. Eine manuelle Krafteinleitung in die Austraghandhabe über ihre durch den zweiten gehäusefesten Anschlag definierte Endlage hinaus führt zu einer Übertragung dieser Kraft mittels des zweiten gehäusefesten Anschlags in das Gehäuse, ohne dabei die Pumpe zu beschädigen.This second housing-fixed stop thus determines indirectly or directly, to what extent the discharge handle can be actuated. Confirmation beyond this is prevented by the second housing-fixed stop. This second housing-fixed stop allows a particularly advantageous adjustment of the adjusting means, since it allows to adjust the adjusting means, while the discharge handle or the first support portion abut the second housing-fixed stop. If in this end position of the discharge handle or the first support portion, the adjusting means is adjusted so that the functional surface of the carrier is spaced relative to the first housing fixed stop so that the pump dispenser is in an actuated state, so as to ensure that in a subsequent Operation in operation of the effective pump stroke of the pump dispenser is exactly completed when the discharge handle or the first support portion comes to rest on the second housing-fixed stop. This provides effective protection of the pump against overstress because the pump can not be compressed beyond its intended pumping stroke. A manual introduction of force into the discharge handle beyond its end position defined by the second housing-fixed stop results in transmission of this force into the housing by means of the second housing-fixed stop without damaging the pump.
Die Schrittweite der axialen Stufung ist vorzugsweise kleiner als ein Millimeter, besonders vorzugsweise kleiner als 0,6 mm, insbesondere kleiner als 0,3 mm sind. Der Vorteil an axial gestuften und vorzugsweise formschlüssig wirkenden Verstellmitteln liegt darin, dass sie abhängig von der Ausgestaltung eine hohe Sicherheit gegen eine ungewollte Rückstellung aufweisen.The step size of the axial graduation is preferably less than one millimeter, more preferably less than 0.6 mm, in particular less than 0.3 mm. The advantage of axially stepped and preferably positively acting adjustment means is that they have a high security against an unwanted provision depending on the design.
Hinsichtlich der Rastmittel wird es bevorzugt angesehen, dass die Rastmittel mehrere Teilrastmittel umfassen, deren jeweilige Raststellungen sich zumindest teilweise voneinander unterscheiden. Hierdurch wird der Vorteil erzielt, dass eine bessonders feine Teilung und damit besonders geringe Schrittweiten erzielbar sind.With regard to the latching means, it is preferably considered that the latching means comprise a plurality of partial latching means, the respective latching positions differ at least partially from each other. This provides the advantage that a bessonders fine division and thus particularly small increments can be achieved.
Dies kann beispielsweise mittels Rastmitteln erreicht werden, die mindestens eine Rastleiter mit Raststufen und der mindestens einen Rastleiter gegenüberliegende zwei Rastnasen umfassen, die zum Zusammenwirken mit der Rastleiter ausgebildet sind. Die Rastnasen sind bezogen auf die Erstreckungsrichtung der Rastleiter quer zu den Raststufen leicht versetzt zueinander angeordnet, vorzugsweise um den halben Abstand der Raststufen der Rastleiter versetzt zueinander. Bei einer Ausführungsform mit einem zweigeteilten Träger kann die Rastleiter beispielsweise umlaufend auf einer Außenseite des zweiten Trägerabschnitts ausgebildet sein, während die Rastnasen auf einer Innenseite des den zweiten Trägerabschnitt umgebenden ersten Trägerabschnitts vorgesehen sind.This can be achieved for example by means of latching means comprising at least one latching conductor with latching steps and the at least one latching conductor opposite two latching noses, which are designed to cooperate with the latching conductor. The latching lugs are arranged offset slightly relative to one another with respect to the extension direction of the latching conductor transversely to the latching steps, preferably offset by half the distance between the latching steps of the latching conductors. In one embodiment with a two-part carrier, the latching conductor can be formed, for example, circumferentially on an outer side of the second carrier section, while the latching lugs are provided on an inner side of the first carrier section surrounding the second carrier section.
Bei einer Weiterbildung der Erfindung ist zwischen dem Funktionsabschnitt des Trägers und dem Pumpspender ein Abstandshalter eingesetzt. Die Verwendung eines solchen Abstandshalters führt dazu, dass ein zweiter Funktionsabschnitt durch den Abstandshalter gebildet wird, der die Funktion des ersten Funktionsabschnitts in Hinblick auf die Krafteinleitung in den Pumpspender übernimmt. Auf dem ersten Funktionsabschnitt ruht der Abstandshalter selbst. Die Verwendung eines solchen Abstandshalters erlaubt die Nutzung der gleichen Austragvorrichtung mit verschiedenen Pumpspendern, die sich insbesondere hinsichtlich der Größe ihres Medienspeichers unterscheiden können. Zwar ist diese Flexibilität auch über eine entsprechende Gestaltung der Verstellmittel realisierbar, bei der Verwendung von Abstandshaltern können die Verstellmittel jedoch wesentlich kleiner ausgestaltet sein, da sie dann nicht primär der Anpassung an verschiedene Pumpspendergrößen, sondern nur dem Ausgleich von Bauteiltoleranzen dienen.In a development of the invention, a spacer is inserted between the functional section of the carrier and the pump dispenser. The use of such a spacer results in that a second functional section is formed by the spacer, which takes over the function of the first functional section with regard to the introduction of force into the pump dispenser. The spacer itself rests on the first functional section. The use of such a spacer allows the use of the same discharge device with different pump dispensers, which may differ in particular with respect to the size of their media storage. Although this flexibility can also be achieved by means of a corresponding design of the adjustment means, the adjustment means can be made substantially smaller in the use of spacers, since they then serve not primarily to adapt to different pump dispenser sizes but only to compensate for component tolerances.
Bei einer Weiterbildung der Erfindung ist das Funktionsabschnitt so angeordnet, dass die Krafteinleitung durch den Funktionsabschnitt auf der dem ersten gehäusefesten Anschlag abgewandten Seite des Pumpspenders erfolgt.In a development of the invention, the functional section is arranged such that the introduction of force takes place through the functional section on the side of the pump dispenser facing away from the first housing-fixed stop.
Im Falle eines üblichen Pumpspenders, der aus einer in etwa zylindrischen Flasche als Medienspeicher sowie einem darauf aufgesetzten Deckel mit Pumpe besteht, würde der Funktionsabschnitt einer Austragvorrichtung gemäß dieser Weiterbildung am Flaschenboden angreifen. Der Vorteil einer Ausgestaltung gemäß dieser Weiterbildung liegt insbesondere darin, dass der Pumpspender durch die Betätigungskraft jeweils in seiner Gesamtheit zusammengedrückt wird, so dass eine besondere Dichtigkeit erzielt wird. Gerade bei einer solchen Ausführungsform sind die Verstellmittel von großem Vorteil, da durch sie auch die Toleranzen im Pumpspender zwischen dem Flaschenboden und dem Pumpsystem des Pumpspenders ausgeglichen werden können.In the case of a conventional pump dispenser, which consists of an approximately cylindrical bottle as a media storage and a lid mounted thereon with a pump, the functional portion of a discharge would attack according to this development on the bottom of the bottle. The advantage of an embodiment according to this development is in particular that the pump dispenser is compressed by the actuating force in each case in its entirety, so that a special tightness is achieved. Especially in such an embodiment, the adjustment means are of great advantage, as they can be compensated by the tolerances in the pump dispenser between the bottle bottom and the pumping system of the pump dispenser.
Bei einer bevorzugten Weiterbildung weist der Träger bzw. der erste Trägerabschnitt an einer dem ersten gehäusefesten Anschlag zugewandten Seite eine vorzugsweise trichterförmige Zentrierhilfe und/oder Führungshilfe zum Verbinden mit einem gehäusefesten Austragkanal auf.In a preferred development, the carrier or the first carrier section has a preferably funnel-shaped centering aid and / or guide aid for connecting to a housing-fixed discharge channel on a side facing the first housing-fixed stop.
Eine solche Ausgestaltung des Trägers ist besonders vorteilhaft bei Austragvorrichtungen, bei denen der Träger in Richtung der Hauptachse in das Gehäuse eingeschoben wird. Bei einer solchen Ausgestaltung ist die korrekte Führung des Trägers erheblich, damit eine Verbindung des Austragkanals mit dem Pumpspender erreicht wird. Darüber hinaus kann eine solche Zentrierhilfe auch als Führungshüfe dienen, indem sie die Lage des Trägers während der axialen Bewegung im Betrieb festlegt.Such a design of the carrier is particularly advantageous in discharge devices in which the carrier is inserted in the direction of the main axis in the housing. In such an embodiment, the correct guidance of the carrier is considerable so that a connection of the discharge channel is achieved with the pump dispenser. In addition, such a centering can also serve as Führungshüfe by determining the position of the carrier during the axial movement during operation.
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, wobei vorzugsweise der Zentrierkonus auf einem Austragsrohr verschiebbar angeordnet ist, welches den ersten gehäusefesten Anschlag bildet und/oder in der die Aufnahmeausnehmung ausgebildet 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 it does not obstruct actuation of the pump dispenser, is displaceably arranged, wherein preferably the centering cone is slidably mounted on a dispensing tube, which forms the first housing-fixed stop and / or in which the receiving recess is formed.
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. 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.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. 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 in the connection areas a positive connection of the Housing shells is provided, by which a displacement of the housing shells against each other is prevented.
Bei einer Weiterbildung der Erfindung ist die Austraghandhabe für eine Austraghandhabung im Wesentlichen quer zur Hauptachse ausgebildet und über mindestens ein separates Übersetzungselement mit dem Träger verbunden. Das Übersetzungselement 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. Eine Betätigung der Austraghandhabe wirkt 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.In a further development of the invention, the discharge handle for discharge handling is formed substantially transversely to the main axis and connected to the carrier via at least one separate transmission element. The translation element 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 the 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. An actuation of the discharge handle acts 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 design of the transmission element as a transmission lever and the design of a translationally movable wedge element or cam element is considered particularly advantageous.
Bei einer Weiterbildung der Erfindung ist die Austraghandhabe als erster Hebel ausgebildet, der um eine Schwenkachse schwenkbar ist, die auf der der Austragöffnung gegenüber liegenden Seite der Austragvorrichtung vorgesehen ist. Durch diese Anordnung der Schwenkachse kann die Austraghandhabe mittels des Daumens der Hand bewegt werden, die die Austraghandhabe umgreift. Dabei bewegen sich die Austraghandhabe und der Daumen 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.In a further development of the invention, the discharge handle is designed as a first lever, which is pivotable about a pivot axis, which is provided on the side opposite the discharge opening of the discharge. By this arrangement of the pivot axis, the discharge handle can be moved by means of the thumb of the hand, which embraces the discharge handle. The discharge handle is moving and the thumb approximately parallel to each other, which is ergonomically advantageous because the force can be applied to the lever not only on the foremost phalanx of the thumb, but over the entire length of the thumb.
Die Erfindung umfasst weiterhin ein Verfahren zur Montage eines Pumpspenders in einer zur Aufnahme eines Pumpspenders vorgesehenen Austragvorrichtung mit einem ersten gehäusefesten Anschlag, wobei der Pumpspender durch Kompression in Richtung einer Hauptachse betätigbar ist, wobei sich das Verfahren dadurch auszeichnet, dass der Pumpspender in die Austragvorrichtung eingelegt wird und mittels eines Verstellmittels eine Justierung der Lage des Pumpspenders in einem komprimierten Zustand des Pumpspenders relativ zur Lage des ersten gehäusefesten Anschlags erfolgt.The invention further comprises a method for mounting a pump dispenser in a discharge device provided for receiving a pump dispenser with a first housing fixed stop, wherein the pump dispenser is actuated by compression in the direction of a main axis, wherein the method is characterized in that the pump dispenser inserted into the discharge is and by means of an adjusting means an adjustment of the position of the pump dispenser in a compressed state of the pump dispenser relative to the position of the first housing-fixed stop.
Bei Austragvorrichtungen, auf die dieses Verfahren anwendbar ist, geht die Betätigung der Austragvorrichtung mit einer Bewegung eines Abschnitts des Pumpspenders einher, der dabei in Richtung des ersten gehäusefesten Anschlags verschoben wird, so dass dieser erste Abschnitt des Pumpspenders gegenüber eines zweiten Abschnittes des Pumpspenders, der im gehäusefesten Anschlag zur Anlage kommt, relativ bewegt wird, was eine Betätigung der pumpspenderseitig vorgesehenen Pumpe zur Folge hat. Die Verstellmittel gestatten dabei, verschiedene Fertigungs- und Montagetoleranzen innerhalb der Austragvorrichtung und insbesondere innerhalb des Pumpspenders durch eine bleibende Justage mittels des Verstellmittels auszugleichen, so dass der Pumpspender sich nach der Justage relativ zum ersten gehäusefesten Anschlag in einer definierten Lage befindet. Dies führt zu einer hohen Reproduzierbarkeit des Verhaltens der Austragvorrichtung bei einer Betätigung. Baugleich Austragvorrichtungen sind trotz unterschiedlicher Bauteiltoleranzen bzgl. ihres Austragsverhalten für den Benutzer nicht zu unterscheiden.In dispensing devices to which this method is applicable, the actuation of the dispensing device is accompanied by a movement of a portion of the pump dispenser which is thereby displaced in the direction of the first housing-fixed abutment, so that this first section of the pump dispenser faces a second section of the pump dispenser comes to rest in the housing fixed stop, is relatively moved, which has an operation of the pump pump side pump provided. The adjustment allow it to compensate for various manufacturing and assembly tolerances within the discharge and in particular within the pump dispenser by a permanent adjustment by means of the adjustment, so that the pump dispenser is located after the adjustment relative to the first housing-fixed stop in a defined position. This leads to a high reproducibility of the behavior of the discharge when actuated. Identical discharge devices are despite their different component tolerances respect. Their discharge behavior for the user indistinguishable.
Im komprimierten Zustand, in dem die Justierung erfolgt, befindet sich die Pumpe im Pumpspender am Ende ihres Pumphubs. Wenn in diesemIn the compressed state in which the adjustment takes place, the pump is located in the pump dispenser at the end of its pumping stroke. If in this
Zustand die Einstellung erfolgt, kann gewährleistet werden, dass bei einer Betätigung einer Austraghandhabe der Austragvorrichtung dieser Zustand reproduzierbar erreicht wird. Dadurch ist gewährleistet, dass der vollständige Pumpenhub durchlaufen wird und damit eine vordefinierte Medienmenge vollständig ausgetragen werden kann.Condition the adjustment is made, it can be ensured that upon actuation of a discharge of the discharge this state is reproducibly achieved. This ensures that the complete pump stroke is passed through and thus a predefined amount of media can be completely discharged.
Bei einer Weiterbildung der Erfindung erfolgt die Justage dahingehend, dass der Pumpspender im betätigten Zustand ist, wenn die Austraghandhabe oder ein mit ihr wirkverbundenes Teil an einem zugeordneten zweiten Anschlag gelangt. Dies bedeutet, dass die Austraghandhabe oder das mit ihr wirkverbundene Bauteil, insbesondere ein Träger zur Aufnahme des Pumpspenders oder der Pumpspender selbst, an den zweiten Anschlag angefahren wird und in diesem Zustand bei komprimiertem Pumpspender die Einstellung derart erfolgt, dass der Pumpspender in dieser Lage gehalten wird. Es erfolgt dadurch eine Normierung eines Zustandes, der im normalen Betrieb der Austragvorrichtung am Ende des Austragvorgangs erreicht wird. Wenn die Austragvorrichtung später im Betrieb betätigt wird, erfolgt demnach eine Komprimierung des Pumpspenders, bis dieser so weit komprimiert ist, dass der Pumphub der im Pumpspender befindlichen Pumpe komplett durchlaufen ist. Sobald dieser Zustand erreicht ist, erreicht die Austraghandhabe oder das mit ihr wirkverbundene Bauteil den zweiten zugeordneten Anschlag, so dass eine Betätigung der Austraghandhabe über diesen Zustand hinaus nicht erfolgen kann. Die im Pumpspender vorgesehene Pumpe wird dadurch vor einer Überbelastung geschützt, denn eine darüber hinausgehende Betätigung der Austraghandhabe wird durch den zweiten Anschlag verhindert.In a further development of the invention, the adjustment takes place to the effect that the pump dispenser is in the actuated state when the dispensing handle or a part operatively connected to it reaches an associated second stop. This means that the discharge handle or the component operatively connected to it, in particular a support for receiving the pump dispenser or the pump dispenser itself, is approached to the second stop and in this state with compressed pump dispenser, the adjustment is made such that the pump dispenser held in this position becomes. This results in a normalization of a state that is reached during normal operation of the discharge at the end of the discharge. If the discharge device is subsequently actuated during operation, compression of the pump dispenser takes place until it has been compressed to such an extent that the pumping stroke of the pump located in the pump dispenser is completed. As soon as this state is reached, the discharge handle or the component operatively connected to it reaches the second associated stop so that actuation of the discharge handle beyond this state can not take place. The pump provided in the pump dispenser is thereby protected against overloading, because an exceeding operation of the discharge handle is prevented by the second stop.

Die
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 istThe
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.

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

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 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 aufgebracht werden. Dies ist unter ergonomischen Gesichtspunkten von Vorteil.The design with two levers, an

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
