Definitions
- the present invention relates in particular to a multi-chamber container having a container housing with at least two chambers arranged one above the other for accommodating product components.
- the multi-chamber container also has a metering element, which conveys the product components by means of the chambers associated with the piston and displaceable in the container longitudinal axis.

- a device for generating a first and / or second product component from the respective chamber aus carenden pressure difference is provided.
- the device which is realized here as a pump, generates an overpressure when actuated in the chamber downstream of the pump. This overpressure is passed on to a next downstream chamber, so that the contained product component is discharged from both chambers.
- the pump is returned to a starting position via a spring. In this return movement results in a negative pressure in both chambers, whereby the pistons of the chambers are moved in the direction of dosing.
- a rotatably mounted metering element it is possible to open or close the discharge openings of the chambers according to the mixing ratio, so that the ratio of the various discharged product components can be varied.
- the disadvantages of the prior art are that the vacuum-induced movement of the pistons deteriorates with increasing viscosity of the product components, and no movement is generated at all beyond a certain degree of viscosity.
- the transferability of the positive / negative pressure from one chamber to the next chamber may decrease.
- the present invention has for its object to provide a multi-chamber container, which promotes the product components from the chambers in an improved manner.
- a multi-chamber container in the context of this invention, a container with at least two, possibly also three or more separate chambers for receiving respectively different product components understood.

- an arrangement between the piston and the element is understood, with which it is possible to transmit forces from the element to the piston.
- the engagement is preferably effected positively and / or non-positively.
- a positive connection in the form of a thread or the like is used.
- engagement means between the piston and the container longitudinal axis which cause a certain positive locking due to wedging, which in any case lead to jamming of the piston with the extending in the direction of the longitudinal axis of the container element, so that only a relative movement of the two elements in one Direction is possible.
- means may be used which cut into the material of the cooperation partner of the engagement to position both elements in a predetermined manner relative to one another.
- the present invention it is possible to displace the pistons arranged in the multi-chamber container in order to discharge the various product components.
- the displacement of all pistons is preferably carried out by means of extending in the container axis element.
- This element has a significantly greater spatial extent in the longitudinal direction than in the transverse direction.
- the element has sufficient shape and material properties to absorb the tensile and / or compressive forces occurring in the multi-chamber container in order to be able to discharge the product components.
- an optionally also variable space is understood, which is suitable for itself or by receiving a bag in the multi-chamber container to be stored and to be delivered by this amount of product.

- the metering member may be rotatably provided to close one or both discharge ports of channels leading to the different chambers, in whole or in part, thereby to vary the mixing ratio of the individual product components dispensed.
- an engagement region located in engagement is formed by a spring washer.
- This spring washer usually interacts with the outer peripheral surface of the piston and, in relative movement of the piston along the container longitudinal axis intersects in each case parallel to this extending element of the multi-chamber container to hold the piston in engagement with this element. Accordingly, the spring washer cooperates with the elements extending in the direction of the longitudinal axis of the container in such a way that a relative movement in one direction between the element and the piston is possible, whereas with a reverse relative movement the spring washer digs into the element and prevents a relative movement.
- the spring washer is preferably provided concentrically to the container longitudinal axis in the engagement region of at least one piston of the multi-chamber container and is preferably by means of injection molding by means of injection molding in the way of producing the piston attached with plastic.

- the push rod is preferably made of plastic, although other materials such as metal can be used.
- the surface of the push rod can be formed either smooth or with depressions, for example in the form of a sawtooth profile for latchable engagement of the spring washer in the push rod.
- the spring washer is preferably bent in the region of the inner diameter in the thrust direction of the push rod. Characterized a substantially translational movement of the push rod is allowed relative to the piston in the thrust direction by the spring washer. In a movement opposite to the thrust direction of the push rod, the spring disc blocks the movement of the push rod, so that the push rod is positively connected to the piston and the piston is taken over the push rod.
- the push rod may comprise an outer push rod and at least one inner push rod.
- these push rods are coupled in the longitudinal direction, so that all push rods cover the same push paths.

- a reverse rotation lock also embodiments are possible in which engage one or more spring tongues in a toothing.
- the suck-back effect usually arises due to the overpressure in the chambers in any case when the spring-back of the piston in the original position preventing means are designed in a corresponding manner.
- a certain play in the above-mentioned reverse rotation lock or the previously described spring washer can allow such a suction effect.
- Also in the preferred provided drive with drive sleeve with teeth and cooperating with the spindle counter teeth may be provided a corresponding clearance, which a certain provision of the piston for retracting the product component in the Multi-chamber container allowed.
- This back suction effect can also be effected by appropriate design of the toothing or the counter toothing.
- the spindle may for example comprise an upper and at least one lower spindle. Also, the spindle may comprise an outer spindle and at least one inner spindle. In the latter arrangement, there is the advantage that each spindle can be assigned a separate drive. These drives can then be designed so that these different spindles are driven at different angular speed.

Description
Die vorliegende Erfindung betrifft im Besonderen einen Mehrkammerbehälter mit einem Behältergehäuse mit wenigstens zwei übereinander angeordneten Kammern zur Aufnahme von Produktkomponenten. Der Mehrkammerbehälter hat ferner ein Dosierelement, welches mittels den Kammern zugeordneter und in Behälterlängsachse verschiebbarer Kolben die Produktkomponenten ausfördert.The present invention relates in particular to a multi-chamber container having a container housing with at least two chambers arranged one above the other for accommodating product components. The multi-chamber container also has a metering element, which conveys the product components by means of the chambers associated with the piston and displaceable in the container longitudinal axis.
Ein gattungsbildender Mehrkammerbehälter, der aufgrund von wenigstens zwei übereinander angeordneten Klammern auch als Mehrkammerbehälter bezeichnet wird, ist beispielsweise aus der
Bei dem vorbekannten Mehrkammerbehälter ist eine Einrichtung zur Erzeugung einer die erste und/oder die zweite Produktkomponente aus der jeweiligen Kammer ausfördernden Druckdifferenz vorgesehen. Die Einrichtung, welche hier als Pumpe realisiert ist, erzeugt beim Betätigen in der der Pumpe nachgeordneten Kammer einen Überdruck. Dieser Überdruck wird an eine nächste nachgeordnete Kammer weitergegeben, so dass aus beiden Kammern die enthaltene Produktkomponente ausgefördert wird. Nach Entnahme der Produktkomponenten, wird die Pumpe über eine Feder wieder in eine Ausgangsstellung zurückgestellt. Bei dieser Rückstellbewegung ergibt sich ein Unterdruck in beiden Kammern, wodurch die Kolben der Kammern in Richtung Dosierkopf bewegt werden. Mittels eines drehbar gelagerten Dosierelementes ist es möglich, die Ausgabeöffnungen der Kammern dem Mischungsverhältnis entsprechend zu öffnen oder zu schließen, so dass das Verhältnis der verschiedenen ausgeförderten Produktkomponenten variiert werden kann.In the previously known multi-chamber container, a device for generating a first and / or second product component from the respective chamber ausfördernden pressure difference is provided. The device, which is realized here as a pump, generates an overpressure when actuated in the chamber downstream of the pump. This overpressure is passed on to a next downstream chamber, so that the contained product component is discharged from both chambers. After removing the product components, the pump is returned to a starting position via a spring. In this return movement results in a negative pressure in both chambers, whereby the pistons of the chambers are moved in the direction of dosing. By means of a rotatably mounted metering element, it is possible to open or close the discharge openings of the chambers according to the mixing ratio, so that the ratio of the various discharged product components can be varied.
Die Nachteile bei dem Stand der Technik sind, dass die durch Unterdruck induzierte Bewegung der Kolben sich mit zunehmender Viskosität der Produktkomponenten verschlechtert und ab einem bestimmten Grad der Viskosität überhaupt keine Bewegung mehr erzeugt wird. Zudem kann auch bei einem Mehrkammerbehälter mit mehreren Kammern die Übertragbarkeit des Über-/Unterdruckes von einer Kammer zu der nächsten Kammer abnehmen.The disadvantages of the prior art are that the vacuum-induced movement of the pistons deteriorates with increasing viscosity of the product components, and no movement is generated at all beyond a certain degree of viscosity. In addition, even with a multi-chamber container having a plurality of chambers, the transferability of the positive / negative pressure from one chamber to the next chamber may decrease.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Mehrkammerbehälter anzugeben, welcher auf verbesserte Weise die Produktkomponenten aus den Kammern ausfördert. Als Mehrkammerbehälter im Sinne dieser Erfindung wird ein Behälter mit wenigstens zwei, gegebenenfalls auch drei oder mehr separaten Kammern zur Aufnahme jeweils unterschiedlicher Produktkomponenten verstanden.The present invention has for its object to provide a multi-chamber container, which promotes the product components from the chambers in an improved manner. As a multi-chamber container in the context of this invention, a container with at least two, possibly also three or more separate chambers for receiving respectively different product components understood.
Zur Lösung dieses Problems wird mit der vorliegenden Erfindung ein Mehrkammerbehälter mit den Merkmalen von Anspruch 1 vorgeschlagen. Dieser unterscheidet sich von dem gattungsbildenden Stand der Technik dadurch, dass wenigstens ein Kolben mit einem sich in Behälterlängsachse erstreckenden Element verschiebbar im Eingriff ist.To solve this problem, a multi-chamber container with the features of claim 1 is proposed by the present invention. This differs from the generic state of the art in that at least one piston is displaceably engaged with an element extending in the container longitudinal axis element.
Mit der Erfindung ist es möglich, auch Produktkomponenten mit sehr hoher Viskosität auszufördern. Auch ist es möglich, durch den direkten Eingriff des sich in Behälterlängsachse erstreckenden Elementes eine genauere Dosierung der einzelnen Produktkomponenten zu erzielen.With the invention it is possible to also produce product components with very high viscosity. It is also possible to achieve a more accurate metering of the individual product components by the direct engagement of extending in the container longitudinal axis element.
Als Eingriff im Sinne der Erfindung wird insbesondere eine Anordnung zwischen Kolben und dem Element verstanden, mit der es möglich ist, Kräfte von dem Element an den Kolben zu übertragen. Der Eingriff wird dabei vorzugsweise form- und/oder kraftschlüssig bewirkt. Besonders bevorzugt kommt eine formschlüssige Verbindung in Form eines Gewindes oder dergleichen zum Einsatz. Denkbar sind auch Eingriffsmittel zwischen dem Kolben und der Behälterlängsachse, die einen gewissen Formschluss aufgrund einer Verkeilung bewirken, die jedenfalls zu einer Verklemmung des Kolbens mit dem sich in Richtung der Längsachse des Behälters erstreckenden Element führen, so dass nur eine Relativbewegung der beiden Elemente in einer Richtung möglich ist. Insbesondere können Mittel zum Einsatz, die in das Material des Kooperationspartners des Eingriffs einschneiden, um beide Elemente in vorbestimmter Weise relativ zueinander zu positionieren.As an intervention in the context of the invention, in particular an arrangement between the piston and the element is understood, with which it is possible to transmit forces from the element to the piston. The engagement is preferably effected positively and / or non-positively. Particularly preferred is a positive connection in the form of a thread or the like is used. Also conceivable are engagement means between the piston and the container longitudinal axis, which cause a certain positive locking due to wedging, which in any case lead to jamming of the piston with the extending in the direction of the longitudinal axis of the container element, so that only a relative movement of the two elements in one Direction is possible. In particular, means may be used which cut into the material of the cooperation partner of the engagement to position both elements in a predetermined manner relative to one another.
Mit der vorliegenden Erfindung ist die Möglichkeit geschaffen, die in dem Mehrkammerbehälter angeordneten Kolben zu verschieben, um die verschiedenen Produktkomponenten auszufördern. Das Verschieben sämtlicher Kolben erfolgt dabei vorzugsweise mittels des sich in Behälterachse erstreckenden Elementes. Dieses Element weist dabei eine deutlich größere räumliche Ausdehnung in Längs- als in Querrichtung auf. Weiter weist das Element ausreichende Form- und Materialeigenschaften auf, um die im Mehrkammerbehälter auftretenden Zug- und/oder Druckkräfte aufzunehmen, um die Produktkomponenten ausfördern zu können.With the present invention, it is possible to displace the pistons arranged in the multi-chamber container in order to discharge the various product components. The displacement of all pistons is preferably carried out by means of extending in the container axis element. This element has a significantly greater spatial extent in the longitudinal direction than in the transverse direction. Furthermore, the element has sufficient shape and material properties to absorb the tensile and / or compressive forces occurring in the multi-chamber container in order to be able to discharge the product components.
Als Kammer im Sinne der Erfindung wird ein gegebenenfalls auch variabler Raum verstanden, der für sich oder durch Aufnahme eines Beutels geeignet ist, die in dem Mehrkammerbehälter zu bevorratende und durch diese auch abzugebende Menge an Produkt aufzunehmen. Als Kammer wird dabei insbesondere ein Aufnahmeraum verstanden, der sich zur Bevorratung einer hinreichenden Menge der Produktkomponente eignet, so dass Produkt mehrfach entnommen werden kann. Das bevorratete Volumen ist im Regelfall groß gegenüber dem beim Dosieren, d.h. der Betätigung des Dosierelementes, ausgegebenen Volumen.As a chamber in the context of the invention, an optionally also variable space is understood, which is suitable for itself or by receiving a bag in the multi-chamber container to be stored and to be delivered by this amount of product. A chamber is to be understood in particular as a receiving space which is suitable for storing a sufficient amount of the product component, so that product can be removed several times. The stored volume is usually large compared to the volume dispensed during dosing, ie the actuation of the dosing element.
Als Dosierelement wird im Sinne der Erfindung ein Element verstanden, welches bei Betätigung die Produktkomponenten aus den Kammern ausfördert. Das Dosierelement ist dabei vorzugsweise am Kopf des Mehrkammerbehälters angeordnet, kann aber beispielsweise auch am Boden des Mehrkammerbehälters ausgebildet sein: Vorzugsweise umfasst das Dosierelement zusätzlich die Ausgabeöffnungen der verschiedenen Kammern. Dabei ist es auch möglich, einzelne Produktkomponenten im Dosierelement zu mischen, und als Gemisch auszugeben. Das Dosierelement kann beispielsweise gemäß der Offenbarung der
Bei einer bevorzugten Ausgestaltung des Mehrkammerbehälters ist ein im Eingriff befindlicher Eingriffsbereich durch eine Federscheibe gebildet. Diese Federscheibe wirkt dabei üblicherweise mit der Außenumfangsfläche des Kolbens zusammen und schneidet sich bei Relativbewegung des Kolbens entlang der Behälterlängsachse jeweils in das sich parallel hierzu erstreckende Element des Mehrkammerbehälters ein, um den Kolben im Eingriff mit diesem Element zu halten. Die Federscheibe wirkt dementsprechend mit dem sich in Richtung der Behälterlängsachse erstreckenden Elemente derart zusammen, dass eine Relativbewegung in einer Richtung zwischen dem Element und dem Kolben möglich ist, wohingegen bei einer umgekehrten Relativbewegung die Federscheibe sich in dem Element verkrallt und eine Relativbewegung verhindert.In a preferred embodiment of the multi-chamber container an engagement region located in engagement is formed by a spring washer. This spring washer usually interacts with the outer peripheral surface of the piston and, in relative movement of the piston along the container longitudinal axis intersects in each case parallel to this extending element of the multi-chamber container to hold the piston in engagement with this element. Accordingly, the spring washer cooperates with the elements extending in the direction of the longitudinal axis of the container in such a way that a relative movement in one direction between the element and the piston is possible, whereas with a reverse relative movement the spring washer digs into the element and prevents a relative movement.
Die Federscheibe ist dabei vorzugsweise konzentrisch zur Behälterlängsachse im Eingriffsbereich wenigstens eines Kolbens des Mehrkammerbehälters vorgesehen und wird vorzugsweise im Wege der Herstellung des Kolbens mittels Spritzgießens durch Umspritzen mit Kunststoff befestigt. Die Federscheibe kann dabei eine Federscheibe aus Metall oder Kunststoff sein. Vorzugsweise ist die Federscheibe als Einlegeteil in eine Spritzgussform eingelegt und bei der Herstellung des Kolbens mittels Spritzgießen durch Umspritzen mit Kunststoff in diesem eingesiegelt. Durch die Federscheibe ragt bevorzugt eine Schubstange, welche mit der Federscheibe zur Übertragung von Kräften mit dem Kolben zusammenwirkt. Als Schubstange im Sinne der Erfindung wird insbesondere eine Stange verstanden, die durch Aufbringen einer Druckkraft in Längsrichtung der Stange eine Verschiebung in Richtung der Längsachse des Mehrkammerbehälters ausführt. Die Schubstange ist bevorzugt aus Kunststoff hergestellt, wobei auch andere Materialien wie z.B. Metall zum Einsatz kommen können. Die Oberfläche der Schubstange kann entweder glatt oder mit Vertiefungen, beispielsweise in Form eines Sägezahnprofils zum rastbaren Eingreifen der Federscheibe in die Schubstange ausgeformt sein. Die Federscheibe ist dabei bevorzugt im Bereich des inneren Durchmessers in Schubrichtung der Schubstange gebogen. Dadurch wird eine im wesentlichen translatorische Bewegung der Schubstange relativ zu dem Kolben in Schubrichtung durch die Federscheibe zugelassen. Bei einer Bewegung entgegengesetzt zu der Schubrichtung der Schubstange blockiert die Federscheibe die Bewegung der Schubstange, so dass die Schubstange formschlüssig mit dem Kolben verbunden ist und der Kolben über die Schubstange mitgenommen wird.The spring washer is preferably provided concentrically to the container longitudinal axis in the engagement region of at least one piston of the multi-chamber container and is preferably by means of injection molding by means of injection molding in the way of producing the piston attached with plastic. The spring washer can be a spring washer made of metal or plastic. Preferably, the spring washer is inserted as an insert in an injection mold and sealed in the manufacture of the piston by injection molding by injection molding with plastic in this. By the spring washer preferably protrudes a push rod which cooperates with the spring washer for transmitting forces to the piston. In the sense of the invention, a push rod is understood to mean, in particular, a rod which, by applying a compressive force in the longitudinal direction of the rod, performs a displacement in the direction of the longitudinal axis of the multi-chamber container. The push rod is preferably made of plastic, although other materials such as metal can be used. The surface of the push rod can be formed either smooth or with depressions, for example in the form of a sawtooth profile for latchable engagement of the spring washer in the push rod. The spring washer is preferably bent in the region of the inner diameter in the thrust direction of the push rod. Characterized a substantially translational movement of the push rod is allowed relative to the piston in the thrust direction by the spring washer. In a movement opposite to the thrust direction of the push rod, the spring disc blocks the movement of the push rod, so that the push rod is positively connected to the piston and the piston is taken over the push rod.
Zu dem vorbeschriebenen Formschluss kommt es, indem die Federscheibe beispielsweise entweder in das Verzahnungsprofil eingreift oder aber bei einer glatten Oberfläche der Schubstange sich in die Oberfläche einschneidet. Bei einer weiteren Ausgestaltung der Schubstange kann die Schubstange eine äußere Schubstange und wenigstens eine innere Schubstange umfassen. Bevorzugterweise sind diese Schubstangen in Längsrichtung gekoppelt, so dass alle Schubstangen die gleichen Schubwege zurücklegen. Es ist aber auch möglich, die äußere Schubstange mit der wenigstens einen inneren Schubstange verschiebbar gegeneinander anzuordnen. Dadurch ist es möglich, die mit den Schubstangen korrespondierenden Kolben aufgrund einer unterschiedlichen Auslenkung der Schubstangen mit unterschiedlichen Wegstrecken zu bewegen.For the above-described form-fit occurs by the spring washer, for example, either engages the tooth profile or with a smooth surface of the push rod cuts into the surface. In a further embodiment of the push rod, the push rod may comprise an outer push rod and at least one inner push rod. Preferably, these push rods are coupled in the longitudinal direction, so that all push rods cover the same push paths. But it is also possible to arrange the outer push rod with the at least one inner push rod slidable against each other. This makes it possible to move the piston corresponding to the push rods due to a different deflection of the push rods with different distances.
Damit bei einem Mehrkammerbehälter alle Kammern mit den Ausgabeöffnungen kommunizieren können, sind jeweils die Schubstangen, die eine Kammer durchsetzen und in die nächste Kammer hineinragen, als Steigrohr ausgebildet. Bei ineinandergreifenden Schubstangen mit unterschiedlichen Durchmessern ist üblicherweise zwischen der äußeren Schubstange und der inneren Schubstange ein Ringkanal gebildet, der als Steigrohr wirkt.In order for all chambers to be able to communicate with the dispensing openings in the case of a multi-chamber container, in each case the push rods which pass through one chamber and protrude into the next chamber are formed as a standpipe. In interlocking push rods with different diameters is usually between the outer Push rod and the inner push rod formed an annular channel, which acts as a riser.
Bei einer alternativen Ausgestaltung des Mehrkammerbehälters ist das Element durch eine Spindel gebildet. Als Spindel im Sinne der Erfindung wird ein Bauteil verstanden, welches eine relative Verdrehung zu einem im Eingriff mit der Spindel stehenden Bauteil zulässt. Diese Spindel ist drehbar gegenüber dem Behältergehäuse beziehungsweise den Kolben gelagert. Die Spindel ist aus Kunststoff oder Metall geformt und weist vorzugsweise außenseitig ein Gewinde auf.In an alternative embodiment of the multi-chamber container, the element is formed by a spindle. As a spindle in the context of the invention, a component is understood, which allows a relative rotation to a standing in engagement with the spindle component. This spindle is rotatably mounted relative to the container housing or the piston. The spindle is molded from plastic or metal and preferably has a thread on the outside.
Angetrieben wird die Spindel kopf- oder fußseitig durch einen Antrieb mit einer Antriebshülse, welche über eine Anlaufschräge einen Mitnehmer antreibt, der eine sich konzentrisch zur Drehachse ausgebildete Verzahnung aufweist, die mit einer konzentrisch zur Drehachse ausgebildeten Gegenverzahnung zusammenwirkt. Über diesen Eingriff kann somit die Dreh- bzw. Schwenkbewegung des Mitnehmers auf die Spindel übertragen werden.The spindle is driven head or foot side by a drive with a drive sleeve which drives a driver via a run-on slope, which has a concentric with the axis of rotation formed teeth, which cooperates with a counter-toothing concentric to the rotational axis. Thus, the rotational or pivotal movement of the driver can be transmitted to the spindle via this engagement.
In einer weiteren Ausführungsform der Spindel ist eine zusätzliche konzentrisch zur Drehachse ausgebildete Verzahnung vorgesehen, die derart in eine Gegenverzahnung eingreift, dass eine Rückdrehbewegung der Spindel blockiert ist. Als Rückdrehsperre sind dabei auch Ausgestaltungen möglich, bei denen eine oder mehrere Federzungen in eine Verzahnung eingreifen. Der Antrieb des Kolbens bei dem erfindungsgemäßen Mehrkammerbehälter erfolgt vorzugsweise derart, dass nach dem Ausfördern von Produktkomponenten aus den Kammern sich ein Rücksaugeffekt einstellt, der die Produktkomponente von der Ausgabeöffnung zurück in das Innere des Behälters zieht, so dass die Produktkomponente nicht an der Ausgabeöffnung ansteht bzw. aus dieser ungewollt heraustritt. Der Rücksaugeffekt stellt sich üblicherweise aufgrund des Überdrucks in den Kammern jedenfalls dann ein, wenn die das Zurückspringen des Kolbens in die Ursprungsstellung verhindernden Mittel in entsprechender Weise ausgelegt sind. So kann ein gewisses Spiel bei der oben genannten Rückdrehsperre bzw. der zuvor bereits beschriebenen Federscheibe einen solchen Rücksaugeffekt ermöglichen. Auch bei dem bevorzugt vorgesehenen Antrieb mit Antriebshülse mit Verzahnung und einer mit der Spindel zusammenwirkenden Gegenverzahnung kann ein entsprechendes Spiel vorgesehen sein, welches eine gewisse Rückstellung des Kolbens zum Zurückziehen der Produktkomponente in den Mehrkammerbehälter erlaubt. Dieser Rücksaugeffekt kann auch durch angemessene Auslegung der Verzahnung bzw. der Gegenverzahnung bewirkt werden.In a further embodiment of the spindle an additional concentric with the axis of rotation formed toothing is provided, which engages in such a counter-toothing, that a reverse rotation of the spindle is blocked. As a reverse rotation lock also embodiments are possible in which engage one or more spring tongues in a toothing. The drive of the piston in the multi-chamber container according to the invention is preferably carried out such that after the removal of product components from the chambers, a suck-back effect occurs, which pulls the product component from the dispensing opening back into the interior of the container, so that the product component is not present at the dispensing opening or . out of this unintentionally emerges. The suck-back effect usually arises due to the overpressure in the chambers in any case when the spring-back of the piston in the original position preventing means are designed in a corresponding manner. Thus, a certain play in the above-mentioned reverse rotation lock or the previously described spring washer can allow such a suction effect. Also in the preferred provided drive with drive sleeve with teeth and cooperating with the spindle counter teeth may be provided a corresponding clearance, which a certain provision of the piston for retracting the product component in the Multi-chamber container allowed. This back suction effect can also be effected by appropriate design of the toothing or the counter toothing.
Die Spindel kann dabei beispielsweise eine obere und wenigstens eine untere Spindel umfassen. Auch kann die Spindel eine äußere Spindel und wenigstens eine innere Spindel umfassen. Bei der zuletzt genannten Anordnung, besteht der Vorteil, dass jeder Spindel ein separater Antrieb zugeordnet sein kann. Diese Antriebe können dann derart gestaltet sein, dass diese verschiedenen Spindeln mit unterschiedlicher Winkelgeschwindigkeit angetrieben werden.The spindle may for example comprise an upper and at least one lower spindle. Also, the spindle may comprise an outer spindle and at least one inner spindle. In the latter arrangement, there is the advantage that each spindle can be assigned a separate drive. These drives can then be designed so that these different spindles are driven at different angular speed.
In einer bevorzugten Ausführungsform ist die äußere Spindel mit der wenigstens einen inneren Spindel bzw. die obere Spindel mit der wenigstens einen unteren Spindel verdrehfest verbunden. Dadurch kann eine Drehbewegung in gleichen Maßen an alle Spindel übertragen werden.In a preferred embodiment, the outer spindle with the at least one inner spindle or the upper spindle with the at least one lower spindle is rotationally connected. As a result, a rotational movement in the same dimensions can be transmitted to all spindle.
Bei der Ausführungsform mit der Spindel kann - wie bei der Ausführungsform mit der Schubstange - jeweils die Spindel, die eine Kammer durchsetzt und in die nächste Kammer hineinragt, als Steigrohr ausgebildet sein. Zur Aufnahme der Produktkomponente aus der entsprechenden Kammer ist das Steigrohr endseitig offen vorgesehen. Bei einer Ausführungsform, bei der eine Spindel mehrere Kammern durchsetzt, können Zulauföffnungen am Umfang der Spindel ausgebildet sein.In the embodiment with the spindle can - as in the embodiment with the push rod - each of the spindle, which passes through a chamber and projects into the next chamber, be formed as a riser. To accommodate the product component from the corresponding chamber, the riser end is provided open. In an embodiment in which a spindle passes through a plurality of chambers, inlet openings may be formed on the circumference of the spindle.
Für den Eingriff mit den Kolben weist die Spindel bevorzugt ein Gewinde auf, welches mit dem Gewinde der Kolben zusammenwirkt. Auch sind Alternativen möglich, bei denen die Spindel eine glatte Oberfläche aufweist und die Kolben selbstschneidende Elemente aus beispielsweise Metall umfassen, die sich formschlüssig an der Spindel, beispielsweise in Form eines Gewindes, entlang einschneiden. Diese Elemente werden ebenso wie die Federscheibe bevorzugt bei der Herstellung des Kolbens mittels Spritzgießens durch Umspritzen mit dem den Kolben ausbildenen Kunststoff befestigt.For engagement with the piston, the spindle preferably has a thread which cooperates with the thread of the piston. Also, alternatives are possible in which the spindle has a smooth surface and the pistons comprise self-tapping elements made of, for example, metal, which cut in a form-locking manner on the spindle, for example in the form of a thread. These elements are preferred as well as the spring washer in the manufacture of the piston by injection molding by injection molding with the plastic forming the piston attached.
Relativbewegungen zwischen den Kolben bei gleicher Winkelgeschwindigkeit der Spindeln sind möglich, wenn die den einzelnen Kolben zugeordneten Spindeln mit unterschiedlichen Gewindesteigungen ausgebildet sind, wie es gemäß einer bevorzugten Weiterbildung der vorliegenden Erfindung vorgeschlagen wird. In dem Zusammenhang ist auch der Einsatz von links- und rechtsläufigen Gewinden denkbar, um z.B. die Kolben in entgegengesetzte Richtung zu verschieben. Für diese Ausführungsform wäre beispielsweise auch eine Spindel mit einem gegenläufigen Gewinde möglich. Es sind auch Ausgestaltungen möglich, bei denen bei einer Spindel Segmente mit unterschiedlichen Gewindesteigungen ausgebildet sind.Relative movements between the pistons at the same angular velocity of the spindles are possible if the spindles associated with the individual pistons are designed with different thread pitches, as proposed according to a preferred development of the present invention. In this context, the use of left- and right-handed threads is conceivable, for example, to move the pistons in the opposite direction. For example, for this embodiment Also a spindle with an opposite thread possible. Embodiments are also possible in which segments with different thread pitches are formed in a spindle.
In einer weiteren bevorzugten Ausgestaltung der Erfindung ergibt sich, dass die Außenspindel ein Innengewinde aufweist. Mit diesem Innengewinde wirkt die Innenspindel zusammen, welche endseitig in einem Kolben verdrehfest gehalten ist. Durch Rotation der Außenspindel können somit Außenspindel und Innenspindel gegeneinander verdreht werden. Auch ist eine Ausgestaltung möglich, bei der die Außenspindel endseitig in einem Kolben verdrehfest gehalten ist und die Innenspindel über einen Antrieb angetrieben ist.In a further preferred embodiment of the invention, it follows that the outer spindle has an internal thread. With this internal thread, the inner spindle cooperates, which is held in a rotationally fixed end in a piston. By rotation of the outer spindle thus outer spindle and inner spindle can be rotated against each other. Also, a configuration is possible in which the outer spindle is held rotationally fixed end in a piston and the inner spindle is driven by a drive.

Die Kolben 4, 8 weisen in an sich bekannter Weise Dichtlippen auf, die mit der Innenumfangsfläche des Behältergehäuses 2 zusammenwirken. Zusätzlich sind die Kolben 4, 8 mit einer Spindel 11 im Eingriff. Die Spindel 11 umfasst eine Außenspindel 20 zum Eingriff mit dem oberen Kolben 8 und eine Innenspindel 22 zum Eingriff mit dem unteren Kolben 4. Die Außenspindel 20, welche verdrehfest mit der Innenspindel 22 verbunden ist, ist zusätzlich derart ausgebildet, dass sie die obere Kammer 12 durchsetzt und dass zwischen Außenspindel 20 und Innenspindel 22 ein Ringskanal 24 gebildet ist, so dass die Außenspindel 20 ein ringförmiges Steigrohr 26 für die Produktkomponente aus der unteren Kammer 10 umgibt. Der Eingriff der Kolbens 4, 8 erfolgt durch selbstschneidende Elemente 28, 30 aus Metall oder Kunststoff, die in den Kolben 4, 8 befestigt sind und derart geformt sind, dass sie ein Gewinde in die glatte Außenumfangsfläche der Spindel 11 schneiden, realisiert.The
Zu der Spindel 11 ist ein Antrieb 31 vorgesehen, der aufgrund der Betätigung des Dosierelementes 14 die so bewirkte translatorische Bewegung des Dosierelementes 14 in eine rotatorische Bewegung der Spindel 11 umsetzt. In
Der Antrieb 31 hat Antriebshülse 32, die verdrehfest, üblicherweise an dem Gehäusekopf 6 befestigt bzw. daran angeformt ist. Die Antriebshülse 32 weist Auflaufschrägen 34 auf, die an gegenüberliegenden Seitenwänden der Antriebshülse 32 vorgesehen sind. Die Auflaufschrägen 34 sind als Nuten an der Antriebshülse 32 ausgebildet. Die Auflaufschrägen 34 wirken mit Mitnehmernocken 36 zusammen, die an einem Mitnehmer 38 ausgebildet sind, der in dem Gehäusekopf 6 drehbar und zumindest geringfügig in Behälterlängsrichtung beweglich aufgenommen ist.

Die Federscheiben 86 wirken lediglich in einer Richtung arretierend mit den Schubstangen 88, 90 zusammen. Wird nun bei Betätigung des Gehäusekopfes 6 dieser gegen die Rückstellkraft der Rückstellfeder 54 nach unten gedrückt, so gleiten die Schubstangen 88, 90 relativ zu den Kolben 4, 8 nach unten und an Krallkanten der Federscheiben 86 vorbei.

Innerhalb der Kappe ist ein eine obere Anlagefläche für die Rückstellfeder 54 ausbildendes Rückstellhalteelement 104 vorgesehen. Eine Drückerbetätigung der Kappe 96 nimmt dieses Rückstellhalteelement 104 mit, wodurch die Rückstellfeder 54 komprimiert wird. Das Rückstellhalteelement 104 bildet des weiteren mit seinen sich parallel zu der Behälterlängsachse innen erstreckenden Schenkeln die Antriebshülse 32 aus, die mit dem Mitnehmer 38 formschlüssig im Eingriff ist, um bei einer axialen Bewegung des Rückstellhalteelementes 104 eine Rotationsbewegung des Mitnehmers 38 zu bewirken.Within the cap, a
Durch die Rotationsbewegung des Mitnehmers 38 wird das Steigrohr 26 und die damit verdrehfest verbundene Spindel 22 in Drehung versetzt, wodurch der untere Kolben 4 angehoben wird. Die Produktmasse in der Kammer 10 wird so über das Steigrohr 26 in dem Maße, wie es die Überschneidung der Öffnung 16 und der korrespondierenden Querbohrung der Kanalabdeckung 100 zulassen ausgefördert. Entsprechend erfolgt die Ausbringung der Produktmasse aus der Kammer 12, wobei der kompressierende Kolben 8 durch das Vorschieben der Produktmasse aus der Kammer 10 in dem Umfang, wie es die Überlappung der korrespondierenden Öffnung 18 und der Querbohrung der Kanalabdeckung 100, erlauben vorgeschoben wird. Befinden die beiden besagten Öffnungen sich nicht in Überschneidung, unterbleibt die Produktausbringung aus der jeweiligen zugeordneten Kammer 10, 12 vollständig und die gesamte Produktmenge wird aus der jeweils anderen Kammer ausgebracht.By the rotational movement of the
Durch die zuvor beispielhaft beschriebene Ausgestaltung ist es möglich, einerseits einen speziellen Antrieb im Sinne der vorliegenden Erfindung anzugeben, welcher eine axiale Bewegung des Gehäusekopfes 6 in eine Drehbewegung der Spindel 11 überführt. Darüber hinaus erlaubt die Ausgestaltung eine Veränderung des Mischungsverhältnisses der ausgeförderten Substanzen aus der jeweiligen Kammer 10, 12.By the embodiment described above by way of example, it is possible, on the one hand, to specify a special drive in the sense of the present invention, which converts an axial movement of the
