Description

Die Erfindung betrifft eine Austragvorrichtung mit einer Betätigungshandhabe, einem ersten Pumpsystem zum Fördern eines ersten Mediums und einem zweiten Pumpsystem zum Fördern eines zweiten Mediums nach dem Oberbegriff von Anspruch 1.The invention relates to a discharge device with an actuating handle, a first pump system for conveying a first medium and a second pump system for conveying a second medium according to the preamble of claim 1.

Bei dem ersten und/oder dem zweiten Medium handelt es sich beispielsweise um ein pastöses Medium wie viskose oder cremeartige Flüssigkeiten, Suspensionen und/oder Fluide, Wasser-in-Öl-Emulsionen (W/O-Emulsionen), Öl-in-Wasser-Emulsionen (O/W-Emulsionen), Oleogele, Hydrogele oder dergleichen. Insbesondere handelt es sich dabei um kosmetische Medien, wie Hautpflegemittel, Lotionen, Haargele, Waschgele oder dergleichen.The first and / or the second medium is, for example, a pasty medium such as viscous or cream-like liquids, suspensions and / or fluids, water-in-oil emulsions (W / O emulsions), oil-in-water Emulsions (O / W emulsions), oleogels, hydrogels or the like. In particular, these are cosmetic media such as skin care products, lotions, hair gels, washing gels or the like.

Aus DE 10110888 A1 ist eine Austragvorrichtung zur gleichzeitigen, dosierten Ausgabe flüssiger und/oder pastöser Medien aus wenigstens zwei Vorratsspeichern bekannt, die in einem gemeinsamen Gehäuse angeordnet sind und denen jeweils separate Pumpsysteme zugeordnet sind. Eine als Hebel gestaltete Betätigungshandhabe ist dabei derart angebracht, dass sie in einer zwischen den Pumpsystemen gelegenen Mittelebene auf ein gemeinsames Betätigungsorgan einwirkt, sodass beide Pumpsysteme gleichgroße Dosierhübe durchführen.Out DE 10110888 A1 a discharge device for the simultaneous, metered dispensing of liquid and / or pasty media from at least two storage reservoirs is known, which are arranged in a common housing and to which separate pump systems are assigned. An actuating handle designed as a lever is attached in such a way that it acts on a common actuating element in a central plane located between the pump systems, so that both pump systems carry out metering strokes of the same size.

Aus der DE 202009014316 U1 ist ein Spender bekannt, bei dem eine Einstelleinrichtung vorgesehen ist, um zeitlich versetzt den Pumpenhub zweier Pumpen zu bewirken. Die Einstelleinrichtung ist als Ring mit angestellter Anlagefläche ausgestaltet, die beim Niederdrücken zunächst eine erste Kolbenstange niederdrückt und später eine andere Kolbenstange.From the DE 202009014316 U1 a dispenser is known in which an adjusting device is provided in order to effect the pump stroke of two pumps with a time offset. The adjustment device is designed as a ring with an engaged contact surface which, when pressed down, first presses down a first piston rod and later another piston rod.

Aus der WO 2010/003091 A1 ist ein Spender mit einer Einstellvorrichtung bekannt, bei der mittels eines Schiebers für einen von zwei Kolben ein Leerweg eingestellt werden kann, entlang dessen eine Drücker zunächst verlagert werden muss, bis der betreffende Kolben niedergedrückt werden kann.From the WO 2010/003091 A1 a dispenser with an adjusting device is known in which an idle travel can be adjusted for one of two pistons by means of a slide, along which a trigger must first be displaced until the piston in question can be depressed.

Aus der DE 69006451 T2 ist ein weiterer Spender bekannt, der über einen gemeinsamen Drücker verfügt, mittels dessen zwei Pumpen gleichzeitig betätigt werden können.From the DE 69006451 T2 Another dispenser is known which has a common pusher by means of which two pumps can be operated simultaneously.

Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Austragvorrichtung mit zwei Pumpsystemen zu schaffen.The invention is based on the object of creating an improved discharge device with two pump systems.

Diese Aufgabe wird gelöst durch den Gegenstand mit den Merkmalen des Anspruchs 1. Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.This object is achieved by the subject matter with the features of claim 1. Further advantageous configurations emerge from the subclaims.

Insbesondere bei kosmetischen Produkten besteht der Bedarf, diese für bestimmte Anforderungen der Nutzer, beispielsweise bestimmte Haar- oder Hauttypen, individuell anzupassen. Um die Zahl an Produkten gleichwohl gering zu halten, ist eine Individualisierung einzelner Produkte durch Mischung von Bestandteilen wünschenswert. Zudem ist eine Mischung von Bestandteilen unmittelbar vor einer Verwendung bei Bestandteilen von Vorteil, welche unterschiedliche Anforderungen an ihre Lagerung stellen und/oder welche bei einer Mischung miteinander reagieren.In the case of cosmetic products in particular, there is a need to adapt them individually to specific user requirements, for example specific hair or skin types. In order to keep the number of products low, individualization of individual products by mixing components is desirable. In addition, a mixture of constituents immediately before use is advantageous for constituents which place different requirements on their storage and / or which react with one another when mixed.

Eine Bewegung der Betätigungshandhabe für einen Austrag erfolgt manuell und/oder mittels einer motorischen Unterstützung.A movement of the actuating handle for a discharge takes place manually and / or by means of a motorized support.

Aufgrund des Leerwegs erfolgt zu Beginn und/oder am Ende einer Bewegung der Betätigungshandhabe zwischen Ausgangslage und Endlage keine Bewegungsübertragung auf den Kolben. Bei einer Rückstellung der Betätigungshandhabe in deren Ausgangslage kann mittels dieser Relativbewegung ein zusätzlicher Rücksaugeffekt erzielt werden, durch welchen eine Menge des verbleibenden Mediums im Bereich einer Austrittsöffnung minimiert wird. Dadurch wird die Gefahr einer Produktantrocknung und somit einer Blockierung im Bereich der Austrittsöffnung verhindert oder zumindest reduziert.Because of the idle travel, no movement is transmitted to the piston at the beginning and / or at the end of a movement of the actuating handle between the starting position and the end position. When the actuating handle is returned to its starting position, this relative movement can be used to achieve an additional suck back effect, by means of which an amount of the remaining medium in the area of an outlet opening is minimized. This prevents or at least reduces the risk of the product drying out and thus blocking in the area of the outlet opening.

In einer Ausgestaltung ist vorgesehen, dass die Betätigungshandhabe und der zweite Kolben derart miteinander gekoppelt sind, dass die Betätigungshandhabe und der zweite Kolben in Betätigungsrichtung über einen zweiten Leerweg relativ zueinander verlagerbar sind, wobei die Distanz zwischen Ausgangslage und Endlage größer als der zweite Leerweg ist. Bei einer Rückstellung der Betätigungshandhabe in deren Ausgangslage kann mittels einer Relativbewegung zwischen dem zweiten Kolben und der Betätigungshandhabe ebenfalls ein zusätzlicher Rücksaugeffekt erzielt werden, durch welchen eine Menge des verbleibenden Mediums im Bereich einer Austrittsöffnung minimiert wird.In one embodiment it is provided that the actuating handle and the second piston are coupled to one another in such a way that the actuating handle and the second piston can be displaced relative to one another in the actuating direction over a second idle travel, the distance between the starting position and the end position being greater than the second idle travel. When the actuating handle is returned to its initial position, a relative movement between the second piston and the actuating handle can also be used to achieve an additional suck back effect, which minimizes a quantity of the remaining medium in the area of an outlet opening.

In einer vorteilhaften Ausgestaltung weichen der erste Leerweg und der zweite Leerweg voneinander ab. Durch die unterschiedlichen Leerwege ist es dabei möglich, mittels einer gemeinsamen Betätigungshandhabe, welche über einen Betätigungshub bewegt wird, unterschiedliche Dosierhübe für die Pumpsysteme zu bewirken und damit unterschiedliche Dosiermengen des ersten und des zweiten Mediums über die zugehörigen Pumpsysteme zu fördern. Ein Dosierhub des ersten Pumpsystems entspricht dabei dem Betätigungshub minus des ersten Leerwegs. Ein Dosierhub des zweiten Pumpsystems entspricht dem Betätigungshub minus des zweiten Leerwegs.In an advantageous embodiment, the first idle travel and the second idle travel differ from one another. The different idle paths make it possible to use a common operating handle, which is moved over an operating stroke, to effect different metering strokes for the pump systems and thus to convey different metering quantities of the first and second medium via the associated pump systems. A metering stroke of the first pump system corresponds to the actuation stroke minus the first idle travel. A metering stroke of the second pump system corresponds to the actuation stroke minus the second idle travel.

In einer besonders bevorzugten Ausgestaltung ist der zweite Kolben spielfrei mit der Betätigungshandhabe wirkverbunden. Das heißt, zwischen dem zweiten Kolben und der Betätigungshandhabe ist kein Leerweg vorgesehen. Ein Dosierhub des zweiten Pumpsystems entspricht dabei dem Betätigungshub. Dadurch erfolgt unmittelbar folgend auf eine Bewegung der Betätigungshandhabe ein Austrag eines Mediums. Dies kann sich vorteilhaft auf eine Wahrnehmung einer Handhabungsqualität durch den Nutzer auswirken.In a particularly preferred embodiment, the second piston is operatively connected to the actuating handle without play. That is, no free travel is provided between the second piston and the actuating handle. A metering stroke of the second pump system corresponds to the actuation stroke. As a result, a medium is discharged immediately following a movement of the actuating handle. This can have an advantageous effect on a perception of a handling quality by the user.

Erfindungsgemäss st das Zwischenstück hülsenförmig, wobei die Betätigungshandhabe und/oder der erste Kolben verschieblich in den Zwischenstück geführt ist. Das Bauteil ist dabei aus einem Material mit einer ausrechenden Steifigkeit, beispielsweise aus Polyamid oder Polypropylen oder aus Metall gefertigt.According to the invention, the intermediate piece is sleeve-shaped, the actuating handle and / or the first piston being guided displaceably into the intermediate piece. The component is made from a material with adequate rigidity, for example from polyamide or polypropylene or from metal.

In einer alternativen Ausgestaltung ist das Zwischenstück reversibel verformbar, wobei die Betätigungshandhabe oder der erste Kolben einteilig mit dem Zwischenstück gefertigt und/oder mit diesem im Wesentlichen spielfrei gekoppelt ist. Das Zwischenstück ist beispielsweise als Faltenbalg aus einem thermoplastischen Material und/oder aus einem elastisch verformbaren Material gefertigt. Das reversibel verformbare Zwischenstück ist in einer Ausgestaltung mit der Betätigungshandhabe oder dem ersten Kolben einteilig gefertigt, beispielsweise als Zwei-Komponenten-Spritzgussteil. Eine Verbindung mit dem jeweils anderen Teil erfolgt beispielsweise stoffschlüssig mittels Schweißen oder Kleben oder kraftschlüssig, wobei elastische Rückstellkräfte des Zwischenstücks nutzbar sind. Alternativ ist das Zwischenstück als separates Bauteil gefertigt und mit beiden Teilen kraft- und/oder stoffschlüssig verbindbar. Das reversibel verformbare Zwischenstück erlaubt eine Relativbewegung des Kolbens und der Betätigungshandhabe um den Leerweg.In an alternative embodiment, the intermediate piece is reversibly deformable, the actuating handle or the first piston being manufactured in one piece with the intermediate piece and / or being coupled to it essentially without play. The intermediate piece is made, for example, as a bellows from a thermoplastic material and / or from an elastically deformable material. The reversibly deformable intermediate piece is manufactured in one embodiment with the actuating handle or the first piston, for example as a two-component injection-molded part. A connection with the respective other part takes place, for example, in a materially bonded manner by means of welding or gluing or non-positively, with elastic restoring forces of the intermediate piece being usable. Alternatively, the intermediate piece is manufactured as a separate component and can be connected to both parts in a non-positive and / or cohesive manner. The reversibly deformable intermediate piece allows a relative movement of the piston and the actuating handle about the free travel.

Erfindungsgemäß ist zwischen dem ersten Kolben und einem Gehäuse der Pumpkammer ein erstes Kraftelement vorgesehen, wobei der erste Kolben entgegen einer Rückstellkraft des ersten Kraftelements für eine Verkleinerung eines Volumens der Pumpkammer verlagerbar ist. Das erste Kraftelement ist in einer Ausgestaltung in der Pumpkammer angeordnet. Insbesondere bei viskosen Medien ist jedoch eine Anordnung des Kraftelements außerhalb der Pumpkammer vorteilhaft. Das erste Kraftelement wird auch als Kolbenrückstellelement bezeichnet.According to the invention, a first force element is provided between the first piston and a housing of the pump chamber, the first piston being displaceable against a restoring force of the first force element to reduce a volume of the pump chamber. In one embodiment, the first force element is arranged in the pump chamber. In particular in the case of viscous media, however, an arrangement of the force element outside the pump chamber is advantageous. The first force element is also referred to as a piston return element.

Alternativ oder zusätzlich ist zwischen dem ersten Kolben und der Betätigungshandhabe in vorteilhaften Ausgestaltungen ein zweites Kraftelement vorgesehen, mittels welchem der erste Kolben und die Betätigungshandhabe auf Abstand gehalten sind. Das zweite Kraftelement dient unter anderem einer Stabilisierung der Bewegung über den Leerweg. Eine Verlagerung der Betätigungshandhabe relativ zu dem Kolben erfolgt entgegen der Kraft des zweiten Kraftelements. Bei einer Gestaltung des Zwischenstücks als elastisches Bauteil fungiert in einer Ausgestaltung das Zwischenstück auch als zweites Kraftelement.Alternatively or in addition, a second force element is provided between the first piston and the actuating handle in advantageous configurations, by means of which the first piston and the actuating handle are kept at a distance. The second force element serves, among other things, to stabilize the movement over the free travel. The actuating handle is shifted relative to the piston against the force of the second Power element. When the intermediate piece is designed as an elastic component, in one configuration the intermediate piece also functions as a second force element.

Das erste und/oder das zweite Kraftelement sind insbesondere als Rückstellfeder gestaltet. Sofern sowohl das erste als auch das zweite Kraftelement vorhanden ist, kann aufgrund einer Wahl der Rückstellkräfte der Kraftelemente festgelegt werden, ob eine Relativbewegung zu Beginn einer Bewegung der Betätigungshandhabe oder an einem Ende der Bewegung erfolgt. Sofern ein zweites Kraftelement mit einer hohen Rückstellkraft eingesetzt ist, werden bei einer Bewegung der Betätigungshandhabe zunächst beide Elemente gemeinsam bewegt bis der erste Kolben eine Endlage erreicht. Bei Erreichen der Endlage des erstens Kolbens führt eine weitere Bewegung der Betätigungshandhabe zu einer Relativbewegung der Betätigungshandhabe relativ zu dem ersten Kolbens über den Leerweg. Sofern ein zweites Kraftelement mit einer niedrigen Rückstellkraft eingesetzt ist, wird bei einer Bewegung der Betätigungshandhabe zunächst die Betätigungshandhabe relativ zu dem ersten Kolben über den Leerweg bewegt. Bei einer Verstellbewegung der Betätigungshandhabe über eine den Leerweg übersteigende Distanz werden die Betätigungshandhabe und der Kolben für einen Produktaustrag gemeinsam bewegt.The first and / or the second force element are designed in particular as a return spring. If both the first and the second force element are present, it can be determined on the basis of a selection of the restoring forces of the force elements whether a relative movement occurs at the beginning of a movement of the actuating handle or at an end of the movement. If a second force element with a high restoring force is used, when the actuating handle is moved, both elements are initially moved together until the first piston reaches an end position. When the end position of the first piston is reached, a further movement of the actuating handle leads to a relative movement of the actuating handle relative to the first piston over the idle travel. If a second force element with a low restoring force is used, when the actuating handle is moved, the actuating handle is initially moved over the idle path relative to the first piston. When the actuating handle is adjusted over a distance exceeding the idle travel, the actuating handle and the piston are moved together for product discharge.

In einer Ausgestaltung sind die Betätigungshandhabe und der erste Kolben in der Ausgangslage miteinander für eine Bewegungsübertragung gekoppelt und werden bei Erreichen einer Endlage des Kolbens für eine Relativbewegung über den Leerweg entkoppelt. In vorteilhaften Ausgestaltungen sind die Betätigungshandhabe und der erste Kolben in der Ausgangslage beabstandet zueinander angeordnet und gelangen bei einer Betätigung der Betätigungshandhabe für einen Austrag nach dem ersten Leerweg für eine Bewegungsübertragung auf Anschlag.In one embodiment, the actuating handle and the first piston are coupled to one another in the starting position for a movement transmission and are decoupled for a relative movement over the idle travel when an end position of the piston is reached. In advantageous refinements, the actuating handle and the first piston are arranged at a distance from one another in the starting position and, when the actuating handle is actuated for a discharge after the first idle travel, come to a stop for a movement transmission.

DETAILLIERTE BESCHREIBUNG DER AUSFÜHRUNGSBEISPIELEDETAILED DESCRIPTION OF THE EMBODIMENTS

Die Figur 1 und 2 zeigen schematisch jeweils ein Ausführungsbeispiel einer Austragvorrichtung 1 mit einer Betätigungshandhabe 2, einem ersten Pumpsystem 3 zum Fördern eines ersten Mediums und einem zweiten Pumpsystem 4 zum Fördern eines zweiten Mediums. Die Medien sind dabei in einem ersten Behälter 30 und einem zweiten Behälter 40 bevorratet. Die dargestellten Austragvorrichtungen 1 umfassen jeweils ein beiden Pumpsystemen 3, 4 gemeinsames Gehäuse 10 und eine beiden Pumpsystemen 3, 4 gemeinsame Kappe 11.The Figure 1 and 2 each schematically show an exemplary embodiment of a discharge device 1 with an actuating handle 2, a first pump system 3 for conveying a first medium and a second pump system 4 for conveying a second medium. The media are stored in a first container 30 and a second container 40. The illustrated discharge devices 1 each include a housing 10 common to both pump systems 3, 4 and a cap 11 common to both pump systems 3, 4.

Der erste Behälter 30 weist in einem Ausführungsbeispiel einen Schleppkolben auf. Der zweite Behälter 40 ist in einem Ausführungsbeispiel für einen Druckausgleich mit der Umgebung kommuniziert. Diese Gestaltung erlaubt es, ein empfindliches Medium in dem ersten Behälter 30 ohne Kontakt mit der Umgebung zu bevorraten, wohingegen ein zweites Medium ohne besondere Schutzvorkehrungen in dem zweiten Behälter 40 bevorratet ist. Die Volumina der zwei Behälter 30, 40 weichen voneinander ab, wobei ein Volumen des zweiten Behälters 30 größer ist als das des ersten Behälters 40. Die beschriebene und/oder dargestellte Gestaltung ist jedoch lediglich beispielhaft und es sind zahlreiche Abwandlungen denkbar.In one embodiment, the first container 30 has a drag piston. In one exemplary embodiment, the second container 40 communicates with the environment for pressure equalization. This design makes it possible to store a sensitive medium in the first container 30 without contact with the environment, whereas a second medium is stored in the second container 40 without special protective measures. The volumes of the two containers 30, 40 differ from one another, with a volume of the second container 30 being greater than that of the first container 40. However, the design described and / or shown is only exemplary and numerous modifications are conceivable.

Die Betätigung beider Pumpsysteme 3, 4 erfolgt über die gemeinsame Betätigungshandhabe 2. An der Betätigungshandhabe 2 ist eine oder sind zwei oder mehr nicht dargestellte Austrittsöffnungen für das erste und das zweite Medium vorgesehen.The actuation of both pump systems 3, 4 takes place via the common actuation handle 2. One or two or more outlet openings (not shown) for the first and second medium are provided on the actuation handle 2.

Ein Fördern des ersten Mediums aus dem Behälter 30 zu der oder den nicht dargestellten Austrittsöffnung(en) erfolgt mittels des ersten Pumpsystems 3. Das dargestellte Pumpsystem 3 umfasst eine erste Pumpkammer 31 und einen verschieblich in der ersten Pumpkammer 31 angeordneten ersten Kolben 32.The first medium is conveyed from the container 30 to the outlet opening (s) (not shown) by means of the first pump system 3. The pump system 3 shown comprises a first pump chamber 31 and a first piston 32 which is displaceably arranged in the first pump chamber 31.

Der erste Kolben 32 ist mehrteilig gestaltet und umfasst ein in der ersten Pumpkammer 31 gelagertes Ringelement 320, ein Stellelement 322 und einen Ventilschieber 324. Der Ventilschieber 324 ist im Wesentlichen spielfrei mit dem Stellelement 322 gekoppelt und mit dem Stellelement 322 relativ zu dem als Ventilsitz fungierenden Ringelement 320 um einen Ventilhub verschieblich. An einem Gehäuse 310 der Pumpkammer 31 ist ein Widerlager 33 ortsfest angebracht. Das Widerlager 33 dient als Anschlag für den Kolben 32 in einer dargestellten oberen Endlage des Kolbens 32. Zwischen dem Kolben 32, genauer zwischen dem Stellelement 322 des Kolbens 32 und dem Widerlager 33 ist ein als Rückstellfeder gestaltetes Kraftelement 34 vorgesehen.The first piston 32 is designed in several parts and comprises a ring element 320 mounted in the first pump chamber 31, an actuating element 322 and a valve slide 324 Valve slide 324 is coupled to actuating element 322 essentially without play and is displaceable with actuating element 322 by one valve stroke relative to ring element 320 functioning as a valve seat. An abutment 33 is fixedly attached to a housing 310 of the pump chamber 31. The abutment 33 serves as a stop for the piston 32 in an illustrated upper end position of the piston 32. Between the piston 32, more precisely between the actuating element 322 of the piston 32 and the abutment 33, a force element 34 designed as a return spring is provided.

Der Kolben 32 ist auf bekannte Weise entgegen einer Rückstellkraft des Kraftelements 34 aus der dargestellten oberen Endlage für eine Verkleinerung eines Volumens der Pumpkammer 31 verlagerbar. Dabei wird zunächst das Stellelement 322 mit dem Ventilschieber 324 relativ zu dem Ringelement 320 verlagert, sodass ein durch den Ventilschieber 324 und das Ringelement gebildetes Auslassventil 35 öffnet. Bei einem Verschieben des Stellelements 322 über eine den Ventilhub übersteigende Distanz gelangt das Stellelement 322 auf Anschlag mit dem Ringelement 320 und die Bewegung des Stellelements wird auf das Ringelement 320 übertragen. Durch Verschieben des Kolbens 32 wird ein in der Pumpkammer 31 vorhandenes Medium verdrängt, sodass das Medium aus der Pumpkammer 31 über das Auslassventil 35 in einen in dem Kolben 32 vorgesehen Auslasskanal 36 gelangt. Der Auslasskanal 36 des Kolbens 32 ist mit einem mit der Austrittsöffnung (nicht dargestellt) kommunizierten Kanal 20 in der Betätigungshandhabe 2 kommuniziert. Bei einer Rückbewegung des Kolbens 32 in die dargestellte Endlage aufgrund der Rückstellkräfte des Kraftelements 34 wird zunächst das Stellelement 322 mit dem Ventilschieber 324 relativ zu dem Ringelement 320 bewegt, so dass das Auslassventil 35 schließt. Aufgrund eines in der Pumpkammer 31 bei der Rückbewegung entstehenden Unterdrucks öffnet das als Kugelventil gestaltete Einlassventil 37, sodass Medium aus dem Behälter 30 für einen Druckausgleich in die Pumpkammer 31 gefördert wird.The piston 32 can be displaced in a known manner against a restoring force of the force element 34 from the illustrated upper end position in order to reduce the volume of the pump chamber 31. In this case, the actuating element 322 with the valve slide 324 is first displaced relative to the ring element 320, so that an outlet valve 35 formed by the valve slide 324 and the ring element opens. When the adjusting element 322 is displaced by a distance exceeding the valve stroke, the adjusting element 322 comes into contact with the ring element 320 and the movement of the adjusting element is transmitted to the ring element 320. By moving the piston 32, a medium present in the pump chamber 31 is displaced, so that the medium passes from the pump chamber 31 via the outlet valve 35 into an outlet channel 36 provided in the piston 32. The outlet channel 36 of the piston 32 communicates with a channel 20 in the actuating handle 2 that is communicated with the outlet opening (not shown). When the piston 32 moves back into the illustrated end position due to the restoring forces of the force element 34, the actuating element 322 with the valve slide 324 is first moved relative to the ring element 320 so that the outlet valve 35 closes. As a result of a negative pressure occurring in the pump chamber 31 during the return movement, the inlet valve 37 designed as a ball valve opens, so that medium is conveyed from the container 30 into the pump chamber 31 for pressure equalization.

Eine Bewegung des Kolbens 32 aus der dargestellten oberen Endlage erfolgt mittels der Betätigungshandhabe 2. Dabei ist die Betätigungshandhabe 2 derart mit dem ersten Kolben 32 gekoppelt, dass die Betätigungshandhabe 2 relativ zu dem Kolben 32 in Betätigungsrichtung über einen Leerweg L verlagerbar ist.The piston 32 is moved out of the upper end position shown by means of the actuating handle 2. The actuating handle 2 is coupled to the first piston 32 in such a way that the actuating handle 2 can be displaced over an idle travel L relative to the piston 32 in the actuating direction.

In dem in Fig. 1 dargestellten Ausführungsbeispiel ist zu diesem Zweck ein starres Zwischenstück 5 vorgesehen, wobei die Betätigungshandhabe 2 und der erste Kolben 32 mittels des Zwischenstücks 5 in Betätigungsrichtung über den Leerweg L relativ zueinander verlagerbar gekoppelt sind.In the in Fig. 1 For this purpose, a rigid intermediate piece 5 is provided for this purpose, wherein the actuating handle 2 and the first piston 32 are coupled by means of the intermediate piece 5 in the actuating direction so that they can be displaced over the idle travel L relative to one another.

Das dargestellte Zwischenstück 5 ist als separates, hülsenförmiges Bauteil gestaltet. Ein derartiges Bauteil ist kostengünstig fertigbar. Das dargestellte Zwischenstück 5 ist zumindest im Wesentlichen spielfrei mit dem Kolben 32, genauer mit dem Stellelement 322 des Kolbens 32 mittels einer Rastverbindung gekoppelt. In anderen Ausgestaltungen ist das Zwischenstück 5 einteilig mit dem ersten Kolben 32, insbesondere dem Stellelement 322 gefertigt. In noch einer anderen Ausgestaltung ist das Zwischenstück 5 einteilig mit der Betätigungshandhabe 2 gefertigt und relativ zu dem Kolben 32 um den Leerweg L verschieblich mit dem Kolben 32 gekoppelt.The illustrated intermediate piece 5 is designed as a separate, sleeve-shaped component. Such a component can be manufactured inexpensively. The illustrated intermediate piece 5 is at least substantially free of play coupled to the piston 32, more precisely to the adjusting element 322 of the piston 32 by means of a latching connection. In other configurations, the intermediate piece 5 is manufactured in one piece with the first piston 32, in particular the adjusting element 322. In yet another embodiment, the intermediate piece 5 is manufactured in one piece with the actuating handle 2 and is coupled to the piston 32 so as to be displaceable relative to the piston 32 by the free travel L.

In dem dargestellten Ausführungsbeispiel ist an der Betätigungshandhabe 2 ein den Kanal 20 aufweisender Zapfen 22 vorgesehen, welcher in dem als Hülse gestalteten Zwischenstück 5 verschieblich geführt ist. Die Betätigungshandhabe 2 und der erste Kolben 32 sind in dem dargestellten Ausführungsbeispiel in einer dargestellten Ausgangslage der Betätigungshandhabe 2 beabstandet zueinander angeordnet. Zwischen dem ersten Kolben 32 und der Betätigungshandhabe 2 ist ein zweites Kraftelement 6 vorgesehen, mittels welchem der erste Kolben 32 und die Betätigungshandhabe 2 auf Abstand gehalten sind. Ein maximaler Abstand ist dabei über Anschläge begrenzt. Das zweite Kraftelement 6 dient dabei auch einer Stabilisierung einer Relativbewegung, sodass ein Verklemmen oder dergleichen vermieden wird.In the illustrated embodiment, a pin 22 having the channel 20 is provided on the actuating handle 2 and is guided displaceably in the intermediate piece 5 designed as a sleeve. In the illustrated embodiment, the actuating handle 2 and the first piston 32 are arranged at a distance from one another in an illustrated starting position of the actuating handle 2. A second force element 6 is provided between the first piston 32 and the actuating handle 2, by means of which the first piston 32 and the actuating handle 2 are kept at a distance. A maximum distance is limited by stops. The second force element 6 also serves to stabilize a relative movement, so that jamming or the like is avoided.

Die Rückstellkräfte des ersten Kraftelements 34 und des zweiten Kraftelements 6 sind beispielsweise derart gewählt, dass bei einer Betätigung der Betätigungshandhabe 2 für einen Austrag zunächst die Betätigungshandhabe 2 ohne Bewegungsübertragung auf den Kolben 32 relativ zu dem Kolben 32 in ihre Ausgangslage bewegt wird. Die Bewegung erfolgt entgegen der Rückstellkraft des zweiten Kraftelements 6. Nach einer Bewegung über eine dem Leerweg L entsprechende Distanz gelangt die Betätigungshandhabe 2, genauer der Zapfen 22 auf Anschlag mit dem Kolben 32, sodass bei einer weiteren Bewegung der Betätigungshandhabe 2 eine Bewegungsübertragung auf den Kolben 32 erfolgt.The restoring forces of the first force element 34 and the second force element 6 are selected, for example, in such a way that when the actuating handle 2 is actuated for a discharge, the actuating handle 2 is initially moved into its starting position without any movement being transmitted to the piston 32 relative to the piston 32. The movement takes place against the restoring force of the second force element 6. After a movement over a distance corresponding to the idle travel L, the actuating handle 2, more precisely the pin 22, comes into contact with the piston 32, so that when the actuating handle 2 moves further, a movement is transmitted to the piston 32 takes place.

Bei Wegfall einer Betätigungskraft bewirkt das erste Kraftelement 32 eine Rückstellbewegung des Kolbens 32 in die dargestellte Endlage des Kolbens 32. Zudem wird die Betätigungshandhabe 2 aufgrund der Rückstellkräfte des zweiten Kraftelements 6 relativ zu dem Kolben 32 bewegt. Mittels dieser Relativbewegung wird ein zusätzlicher Rücksaugeffekt erzielt, durch welchen ein an der nicht dargestellten Austrittsöffnung verbliebenes Medium in den Kanal 20 und/oder den Auslasskanal 36 gesogen wird. Dadurch wird die Gefahr einer Produktantrocknung und somit einer Blockierung im Bereich der Austrittsöffnung verhindert oder zumindest reduziert.When an actuating force is lost, the first force element 32 effects a return movement of the piston 32 into the illustrated end position of the piston 32. In addition, the actuating handle 2 is moved relative to the piston 32 due to the restoring forces of the second force element 6. By means of this relative movement, an additional back suction effect is achieved, by means of which a medium remaining at the outlet opening (not shown) is sucked into the channel 20 and / or the outlet channel 36. This prevents or at least reduces the risk of the product drying out and thus blocking in the area of the outlet opening.

Fig. 2 zeigt eine alternative Ausgestaltung. Im Unterschied zu der Ausgestaltung gemäß Fig. 1 ist ein zumindest teilweise reversibel verformbares Zwischenstück 105 vorgesehen, wobei auch bei dieser Ausgestaltung die Betätigungshandhabe 2 und der erste Kolben 32 mittels des Zwischenstücks 105 in Betätigungsrichtung über den Leerweg L relativ zueinander verlagerbar gekoppelt sind. Das reversibel verformbare Zwischenstück 105 ist beispielsweise aus einem elastisch verformbaren Material gefertigt und/oder als Faltenbalg gestaltet. Fig. 2 shows an alternative embodiment. In contrast to the design according to Fig. 1 an at least partially reversibly deformable intermediate piece 105 is provided, with the actuating handle 2 and the first piston 32 also being coupled in the actuating direction via the idle travel L relative to one another by means of the intermediate piece 105. The reversibly deformable intermediate piece 105 is made, for example, of an elastically deformable material and / or designed as a bellows.

Das in Fig. 2 dargestellte Zwischenstück 105 ist ebenfalls als separates Bauteil gestaltet, welches mit dem Kolben 32, genauer mit dem Stellelement 322 des Kolbens 32, und mit der Betätigungshandhabe, genauer mit dem Zapfen 22 der Betätigungshandhabe gekoppelt ist. Eine Verbindung erfolgt kraft- oder stoffschlüssig. In anderen Ausgestaltungen ist das Zwischenstück 105 einteilig, beispielsweise als Zwei-Komponenten-Spritzgussteil mit dem Stellelement 322 oder der Betätigungshandhabe 2 gefertigt.This in Fig. 2 The intermediate piece 105 shown is also designed as a separate component which is coupled to the piston 32, more precisely to the actuating element 322 of the piston 32, and to the actuating handle, more precisely to the pin 22 of the actuating handle. A connection is made with a force-fit or material fit. In other configurations, the intermediate piece 105 is made in one piece, for example as a two-component injection-molded part with the adjusting element 322 or the actuating handle 2.

Bei der in Fig. 2 dargestellten Ausführungsform übernimmt das elastisch verformbare Zwischenstück 105 auch die Funktion des Kraftelements 6 gemäß Fig. 1. In anderen Ausgestaltungen ist ein zusätzliches Kraftelement vorgesehen.At the in Fig. 2 illustrated embodiment, the elastically deformable intermediate piece 105 also takes over the function of the force element 6 according to Fig. 1 . In other configurations, an additional force element is provided.

In beiden in Fig. 1 und 2 dargestellten Ausführungsbeispielen ist wie erwähnt weiter ein zweites Pumpsystem 4 vorgesehen. Das zweite Pumpsystem 4 umfasst einen, in einer zweiten Pumpkammer 41 geführten zweiten Kolben 42. Der zweite Kolben 42 ist ebenfalls mehrteilig gestaltet und umfasst ein in der zweiten Pumpkammer 42 gelagertes Ringelement 420 und ein Stellelement 422. Der zweite Kolben 42 umfasst ein Widerlager 424 für ein in der Pumpkammer 41 angeordnetes Kraftelement 44.In both in Fig. 1 and 2 As mentioned, a second pump system 4 is also provided in the illustrated embodiments. The second pump system 4 comprises a second piston 42 guided in a second pump chamber 41. The second piston 42 is also designed in several parts and comprises a ring element 420 mounted in the second pump chamber 42 and an actuating element 422. The second piston 42 comprises an abutment 424 for a force element 44 arranged in the pump chamber 41.

Der Kolben 42, genauer das Stellelement 422 des Kolbens 42 ist in dem dargestellten Ausführungsbeispiel zumindest im Wesentlichen spielfrei mit der Betätigungshandhabe 2 gekoppelt, sodass eine unmittelbare Bewegungsübertragung von der Betätigungshandhabe 2 auf den Kolben 42 erfolgt.The piston 42, more precisely the adjusting element 422 of the piston 42, is coupled to the actuating handle 2 at least essentially without play in the illustrated embodiment, so that a direct transfer of movement from the actuating handle 2 to the piston 42 takes place.

Für einen Austrag werden die Pumpsysteme 3, 4 gemeinsam über die Betätigungshandhabe betätigt. Ein Dosiervolumen des zweiten Pumpsystems 4 ist in dem dargestellten Ausführungsbeispiel jedoch größer als das des ersten Pumpsystems 3, sodass ein längerer Hub für einen vollständigen Austrag notwendig ist. Mittels des Abstands zwischen der Betätigungshandhabe 2 und dem Kolben 32 wird in dem dargestellten Ausführungsbeispiel ein Ausgleich geschaffen, wobei der Hub des ersten Kolbens 32 um eine dem Leerweg L entsprechende Länge kürzer ist als der des zweiten Kolbens 42.For a discharge, the pump systems 3, 4 are actuated jointly via the actuating handle. In the exemplary embodiment shown, however, a metering volume of the second pump system 4 is greater than that of the first pump system 3, so that a longer stroke is necessary for complete discharge. In the exemplary embodiment shown, compensation is created by means of the distance between the actuating handle 2 and the piston 32, the stroke of the first piston 32 being shorter than that of the second piston 42 by a length corresponding to the free travel L.
