Description

Die vorliegende Erfindung betrifft ein Dosierventil zur Abgabe einer vorzugsweise kosmetischen Flüssigkeit gemäß dem Oberbegriff des Anspruchs 1, eine Vorrichtung mit einem derartigen Dosierventil, und ein Verfahren zum Herstellen eines derartigen Dosierventils.The present invention relates to a metering valve for dispensing a preferably cosmetic liquid according to the preamble of claim 1, a device with such a metering valve, and a method for producing such a metering valve.

Unter dem Begriff "kosmetische Flüssigkeit" sind in einem engeren Sinn Haarspray, Haarlack, ein Deodorant, ein Schaum, ein Gel, ein Farbspray, ein Sonnen- oder Hautpflegemittel o. dgl. zu verstehen. Vorzugsweise werden in einem weiteren Sinn aber auch sonstige Körperpflegeprodukte, Reinigungsprodukte, Kosmetika o. dgl., und auch Suspensionen und Fluide, insbesondere mit Gasphasen, umfaßt. Jedoch können als sonstige Flüssigkeiten, beispielsweise Luftverbesserer, und insbesondere auch technische Flüssigkeiten und Fluide, wie Rostlöser o. dgl., eingesetzt werden. Nachfolgend wird jedoch aus Vereinfachungsgründen und aufgrund des Nutzungsschwerpunkts oft nur von kosmetischer Flüssigkeit gesprochen.The term "cosmetic liquid" is to be understood in a narrow sense hair spray, hair lacquer, a deodorant, a foam, a gel, a paint spray, a sunscreen or skin care agent o. The like. In a broader sense, however, other personal care products, cleansing products, cosmetics o. The like., And also suspensions and fluids, in particular with gas phases, are preferably included. However, as other liquids, such as air freshener, and in particular also technical fluids and fluids, such as rust remover o. The like., Are used. However, for reasons of simplification and because of the focus of use, only cosmetic liquid is often referred to below.

Aus der US 2003/0230603 A1 ist eine Vorrichtung zur dosierten Zerstäubung einer kosmetischen Flüssigkeit bekannt, wobei ein die Flüssigkeit enthaltender Behälter ein Dosierventil mit einem bewegbaren Ventilelement in einem Ventilgehäuse aufweist. Das Ventilelement bildet zusammen mit dem Ventilgehäuse ein zulaufseitiges Einlaßventil und ein abgabeseitiges Auslaßventil. Das Ventilelement ist vorzugsweise mit einem aufgesteckten Sprühkopf o. dgl. zur Abgabe und Zerstäubung der Flüssigkeit versehen. Durch Niederdrücken des Sprühkopfes wird das Ventilelement axial bewegt, wodurch zunächst das zulaufseitige Einlaßventil des Dosierventils geschlossen und erst anschließend das abgabeseitige Auslaßventil des Dosierventils geöffnet wird. Dann kann die vorzugsweise ein Treibmittel enthaltende Flüssigkeit aus dem im Ventilgehäuse gebildeten Dosierraum entweichen und vom angeschlossenen Sprühkopf zerstäubt und ausgegeben werden.From the US 2003/0230603 A1 a device for the metered atomization of a cosmetic liquid is known, wherein a container containing the liquid comprises a metering valve with a movable valve element in a valve housing. The valve element together with the valve housing forms an inlet-side inlet valve and a discharge-side outlet valve. The valve element is preferably provided with an attached spray head o. The like. For dispensing and atomization of the liquid. By depressing the spray head, the valve element is moved axially, whereby initially the inlet-side inlet valve of the metering valve is closed and only then the discharge-side outlet valve of the metering valve is opened. Then, the liquid preferably containing a blowing agent can escape from the metering chamber formed in the valve housing and be atomized and dispensed by the connected spray head.

Um die gewünschte Dichtwirkung zwischen dem Ventilelement einerseits und dem Ventilgehäuse andererseits zu erreichen, ist eine Dichtung an das bewegbare Ventilelement angespritzt, die bei geschlossenem Einlaßventil axial dichtet. Das bekannte Dosierventil gestattet keine optimale Abdichtung. Die US 3073 489 A zeigt ein Dosierventil mit den Merkmalen des Oberbegriffs des Auspruchs 1. Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Dosierventil und eine Vorrichtung zur dosierten Abgabe einer vorzugsweise kosmetischen Flüssigkeit sowie ein Verfahren zur Herstellung eines derartigen Dosierventils anzugeben, wobei das Dosierventil eine optimale Abdichtung gestattet und universeller einsetzbar ist.In order to achieve the desired sealing effect between the valve element on the one hand and the valve housing on the other hand, a seal is molded onto the movable valve element, which seals axially with the inlet valve closed. The known metering valve does not allow optimal sealing. The US 3,073,489 A shows a metering valve with the features of the preamble of claim 1. The present invention has for its object to provide a metering valve and a device for the metered delivery of a preferably cosmetic liquid and a method for producing such a metering valve, wherein the metering valve allows optimal sealing and is universally applicable.

Die obiger Aufgabe wird durch ein Dosierventil gemäß Anspruch 1, eine Vorrichtung gemäß Anspruch 12, oder ein Verfahren gemäß Anspruch 15 gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.The above object is achieved by a metering valve according to claim 1, an apparatus according to claim 12, or a method according to claim 15. Advantageous developments are the subject of the dependent claims.

Vorschlagsgemäß weist das Ventilelement einen in Bewegungsrichtung federnden Federabschnitt und einen sich anschließenden Kopfabschnitt auf, wobei der Kopfabschnitt vorzugsweise das Einlaßventil bildet und insbesondere das vorzugsweise angespritzte Dichtungselement trägt. Hierdurch ergibt sich jeweils ein sehr einfacher Aufbau mit wenigen Teilen, so daß eine kostengünstige Herstellung und Montage ermöglicht werden. Weiter ermöglicht dies eine optimierte Abdichtung, da der Kopfabschnitt mit dem Dichtungselement optimal abdichtend an einen zugeordneten Ventilsitz am Ventilgehäuse sich anlegen oder darin eingreifen kann.According to the proposal, the valve element has a resilient in the direction of movement spring portion and a subsequent head portion, wherein the head portion preferably forms the inlet valve and in particular carries the preferably molded sealing element. This results in each case a very simple structure with few parts, so that a cost-effective production and assembly are possible. Furthermore, this makes possible an optimized sealing, since the head section with the sealing element can optimally seal against or engage in an associated valve seat on the valve housing.

Das Dichtungselement besteht vorzugsweise aus einem weicheren oder elastischeren Material als das Ventilelement und das Ventilgehäuse. Dies ermöglicht eine wesentlich stabilere Ausbildung des Dosierventils, insbesondere des Ventilgehäuses, das dementsprechend besser höheren Treibmittel- und Fülldrücken standhalten kann. Daher sind das vorschlagsgemäße Dosierventil und eine mit einem derartigen Dosierventil versehene Vorrichtung universell einsetzbar.The sealing element is preferably made of a softer or more elastic material than the valve element and the valve housing. This allows a much more stable design of the metering valve, in particular the valve housing, which can therefore withstand better higher blowing agent and filling pressures accordingly. Therefore, the proposed metering valve and a device provided with such a metering device are universally applicable.

Gemäß einer besonders bevorzugten Ausführungsform ist das Dichtungselement unmittelbar an das Ventilelement angespritzt. Dies kann beispielsweise direkt in der Spritzgießform für das Ventilelement erfolgen. Bedarfsweise kann das Dichtungselement auch als vorgefertigtes Teil in die Spritzgießform eingesetzt und das Ventilelement an das Dichtungselement angespritzt werden. In beiden Fällen wird eine besonders einfache und kostengünstige Herstellung ermöglicht, wobei die Montage in der bisher üblichen Weise ohne zusätzlichen Montageschritt für das Dichtungselement erfolgen kann.According to a particularly preferred embodiment, the sealing element is molded directly onto the valve element. This can be done, for example, directly in the injection mold for the valve element. If necessary, the sealing element can also be used as a prefabricated part in the injection mold and the valve element are molded onto the sealing element. In both cases, a particularly simple and cost-effective production is made possible, wherein the assembly can be done in the usual manner without additional mounting step for the sealing element.

Entsprechende Vorteile ergeben sich, wenn das Dichtungselement am Ventilelement insbesondere durch Aufstecken angebracht wird.Corresponding advantages arise when the sealing element is attached to the valve element in particular by plugging.

Vorzugsweise ist das Dichtungselement im Bereich eines freien Endes am Ventilelement angeordnet. Dies ist insbesondere einer entsprechend endseitigen Anordnung des Einlaßventils und einem möglichen Aufstecken des Dichtungselements auf das Ventilelement zuträglich.Preferably, the sealing element is arranged in the region of a free end on the valve element. This is in particular a corresponding end-side arrangement of the inlet valve and a possible attachment of the sealing element on the valve element beneficial.

Vorzugsweise sind das Dichtungselement, das Ventilelement und das Ventilgehäuse jeweils aus Kunststoff spritzgegossen, um eine kostengünstige Massenfertigung zu ermöglichen.Preferably, the sealing element, the valve element and the valve housing are each injection molded from plastic to enable a cost-effective mass production.

Vorzugsweise erfolgt das Spritzgießen mit einer derartigen Präzision und eine derartige Wahl der Materialien, daß keine Nachbearbeitung zur Erzielung der gewünschten Dichtwirkung erforderlich ist.Preferably, the injection molding is done with such precision and such a choice of materials that no post-processing to achieve the desired sealing effect is required.

Insbesondere ist das Dichtungselement selbstsichernd ausgebildet. Dies kann beispielsweise dadurch erreicht werden, daß das Dichtungselement in eine vorzugsweise hinterschnittene Aussparung des Ventilelements oder des Ventilgehäuses eingreift. Besonders bevorzugt wird dies jedoch dadurch erreicht, daß das Dichtungselement unmittelbar an das Ventilelement oder das Ventil angespritzt bzw. darin eingespritzt wird oder umgekehrt, um einen nichtlösbaren Verbund zu bilden.In particular, the sealing element is self-locking. This can be achieved, for example, in that the sealing element engages in a preferably undercut recess of the valve element or the valve housing. However, this is achieved in a particularly preferred manner by the sealing element being injection-molded or injected directly onto the valve element or the valve or vice versa, in order to form a non-detachable composite.

Besonders bevorzugt wird das Dosierventil zur dosierten Abgabe einer kosmetischen Flüssigkeit verwendet, die Partikel enthält, wobei verteilte Vorsprünge in einem Dosierraum des Dosierventils zur temporären Ablagerung der Partikel verwendet werden, um einem bodenseitigen Absetzen der Partikel und insbesondere Zusetzen des Einlaßventils entgegenzuwirken, wobei die auf den Vorsprüngen abgesetzten Partikel von der Flüssigkeit bei der Abgabe mit ausgetragen werden. So wird eine bessere Verteilung der Partikel in der ausgetragenen Flüssigkeit ermöglicht. Dies ist für partikelhaltige Formulierungen bzw. Suspensionen, die zunehmend verwendet werden, zuträglich, um möglichst gleichmäßige Verteilungen und damit einheitliche Eigenschaften sicherstellen zu können.Particularly preferably, the metering valve is used for metered delivery of a cosmetic liquid containing particles, wherein distributed projections in a metering chamber of the metering valve for temporary deposition the particles are used to counteract a bottom-side settling of the particles and in particular clogging of the inlet valve, wherein the deposited on the projections particles are discharged by the liquid in the discharge. This allows a better distribution of the particles in the discharged liquid. This is beneficial for particle-containing formulations or suspensions, which are increasingly being used, in order to be able to ensure as uniform a distribution as possible and thus uniform properties.

Beim Betätigen des Ventilelements 6 - also Herunterdrücken des Ventilelements 6 gegen die Kraft der Rückstellfeder 12 - wird zunächst das Einlaßventil 9 geschlossen und erst danach das Auslaßventil 10 geöffnet. In diesem betätigten Zustand kann dann die im Dosierraum 11 befindliche Flüssigkeit 3 über das geöffnete Auslaßventil 10 abgegeben werden, insbesondere aufgrund des genannten Treibmittels selbstständig ausströmen und beispielsweise von dem an das Anschlußstück 8 angeschlossenen, nicht dargestellten Sprühkopf versprüht bzw. zerstäubt werden. Das Dosierventil 2 gibt dementsprechend bei jeder Betätigung nur eine bestimmte bzw. dosierte Menge an Flüssigkeit 3 ab.Upon actuation of the valve element 6 - ie pushing down of the valve element 6 against the force of the return spring 12 - the inlet valve 9 is first closed and only then the exhaust valve 10 is opened. In this actuated state, the liquid 3 located in the dosing chamber 11 can then be discharged via the opened outlet valve 10, in particular due to the said blowing agent to flow independently and, for example, sprayed or atomized by the spray head, not shown, connected to the connecting piece 8. Accordingly, the metering valve 2 dispenses only a specific or metered quantity of liquid 3 with each actuation.

Beim Rückstellen des Dosierventils 2 in die unbetätigte Stellung wird erst das Auslaßventil 10 geschlossen und erst dann das Einlaßventil 9 geöffnet, um Flüssigkeit 3 in den Dosierraum 11 nachströmen zu lassen.When resetting the metering valve 2 in the unactuated position, only the exhaust valve 10 is closed and only then the inlet valve 9 is opened to allow liquid 3 to flow into the metering chamber 11.

Das Ventilelement 6 und das Ventilgehäuse 7 sind vorzugsweise jeweils einstückig ausgebildet und aus Kunststoff spritzgegossen, insbesondere aus einem relativ harten bzw. steifen Kunststoff, wie Polyamid oder Polyoxymethylen (POM).The valve element 6 and the valve housing 7 are preferably each formed in one piece and injection molded from plastic, in particular from a relatively hard or rigid plastic, such as polyamide or polyoxymethylene (POM).

Zur Abdichtung des Einlaßventils 9 im geschlossenen Zustand ist vorschlagsgemäß zusätzlich zwischen dem Ventilelement 6 und dem Ventilgehäuse 7 ein Dichtungselement 14 aus einem weicheren oder elastischeren Material als das Ventilelement 6 und das Ventilgehäuse 7 vorgesehen.To seal the intake valve 9 in the closed state, a sealing element 14 made of a softer or more elastic material than the valve element 6 and the valve housing 7 is also provided according to the proposal between the valve element 6 and the valve housing.

Vorzugsweise ist das Dichtungselement 14 an das Ventilelement 6 angespritzt, vorzugsweise unmittelbar in der zur Herstellung des Ventilelements 6 verwendeten Spritzgußform oder in einer separaten Spritzgußform. Alternativ kann das Dichtungselement 14 beispielsweise auch als vorgefertigtes Teil in die Spritzgußform eingelegt und das Ventilelement 6 angespritzt sein oder das Dichtungselement 14 auf das vorgefertigte Ventilelement 6 aufgesteckt sein.Preferably, the sealing element 14 is molded onto the valve element 6, preferably directly in the injection mold used for producing the valve element 6 or in a separate injection mold. Alternatively, the sealing element 14 may for example also be inserted as a prefabricated part into the injection mold and the valve element 6 may be injection-molded or the sealing element 14 may be attached to the prefabricated valve element 6.

Das Dichtungselement 14 ist vorzugsweise auch spritzgegossen, insbesondere aus einem geeigneten Elastomer, vorzugsweise aus einem thermoplastischen Elastomer (TPE), einem thermoplastischen Polyurethan (TPU) oder unter hohem Druck hergestelltem Polyethylen niedriger Dichte (LDPE).The sealing element 14 is also preferably injection molded, in particular of a suitable elastomer, preferably of a thermoplastic elastomer (TPE), a thermoplastic polyurethane (TPU) or high pressure produced low density polyethylene (LDPE).

Durch das Spritzgießen wird eine kostengünstige Massenfertigung ermöglicht, insbesondere wobei eine Nachbearbeitung der Dichtungsflächen - einerseits am Dichtungselement 14 und andererseits am Ventilelement 6 oder Ventilgehäuse 7 - nicht erforderlich ist.By injection molding a cost-effective mass production is possible, in particular wherein a reworking of the sealing surfaces - on the one hand on the sealing element 14 and on the other hand on the valve element 6 or valve housing 7 - is not required.

Das Anspritzen des Dichtungselements 14 an das Ventilelement 6 hat den Vorteil, daß das Dichtungselement 14 kein separates Teil bildet und daher keinen separaten Montageschritt erfordert und darüber hinaus den weiteren Vorteil, daß eine sehr gute Abdichtung zwischen dem Dichtungselement 14 und dem damit verbundenen Ventilelement 6 oder Ventilgehäuse 7 ohne zusätzliche Maßnahmen erreichbar ist.The injection of the sealing member 14 to the valve element 6 has the advantage that the sealing member 14 forms no separate part and therefore does not require a separate assembly step and beyond the further advantage that a very good seal between the sealing member 14 and the associated valve member 6 or Valve housing 7 can be reached without additional measures.

Das Dichtungselement 14 ist am Ventilelement 6 angeordnet und weist beim Darstellungsbeispiel vorzugsweise einen kegelstumpfförmigen, konischen, balligen, halbkugelförmigen oder abgerundeten Einführbereich 15 auf, um ein Einführen in einen korrespondierenden Dichtungsabschnitt des Ventilgehäuses 7 zur Abdichtung gegen das Dichtungselement 14 bei geschlossenem Einlaßventil 9 zu erleichtern.The sealing element 14 is arranged on the valve element 6 and, in the illustrated embodiment, preferably has a frusto-conical, conical, spherical, hemispherical or rounded insertion region 15 in order to be inserted into a corresponding sealing section of the valve housing 7 to facilitate sealing against the sealing element 14 with the inlet valve 9 closed.

Beim Darstellungsbeispiel ist das Dichtungselement 14 an einem freien Ende des Ventilelements 6 derart angeordnet, daß im unbetätigten Zustand ein axialer Zulaufkanal 17 im Ventilgehäuse 7 zum Dosierraum 11 nicht blockiert wird. Im betätigten Zustand - also bei niedergedrücktem Ventilelement 6 - ist das Ventilelement 14 vorzugsweise zumindest teilweise mit einem vorderen Ende des Ventilelements 6 in den Zuführkanal 17 zur radialen und/oder axialen Abdichtung an einem Dichtungsabschnitt des Ventilgehäuses 7 eingeführt. Jedoch sind grundsätzlich auch andere Ventilkonstruktionen möglich, beispielsweise eine tellerartige Ausbildung und/oder eine axiale Abdichtung.In the illustrated example, the sealing element 14 is arranged at a free end of the valve element 6 such that in the unactuated state, an axial inlet channel 17 in the valve housing 7 to the dosing chamber 11 is not blocked. In the actuated state - ie when depressed valve element 6 - the valve element 14 is preferably at least partially inserted with a front end of the valve element 6 in the supply channel 17 for radial and / or axial sealing at a sealing portion of the valve housing 7. However, in principle, other valve designs are possible, for example, a plate-like design and / or an axial seal.

Das einstückige Ventilelement 6 weist im Bereich seines vorderen bzw. freien Endes einen in Axial- bzw. Bewegungsrichtung B federnden Federabschnitt 21 und einen sich daran anschließenden Kopfabschnitt 22 auf. Das Dichtungselement 14 ist vorzugsweise zumindest im wesentlichen ausschließlich stirnseitig am Kopfabschnitt 22 angeordnet, vorzugsweise angespritzt.The one-piece valve element 6 has, in the region of its front or free end, a spring section 21, which is resilient in the axial direction or movement direction B, and an adjoining head section 22. The sealing element 14 is preferably arranged at least substantially exclusively on the front side of the head portion 22, preferably molded.

Beim Darstellungsbeispiel dichtet das Einlaßventil 9 zumindest im wesentlichen axial, indem das Dichtungselement 14 bei Betätigung des Ventilelements 6 an einem geeigneten, vorzugsweise konischen Schulterbereich 16 oder sonstigen Ventilsitz des Ventilgehäuses 7 zur Anlage kommt, wodurch das Einlaßventil 9 schließt. Im Verlauf der weiteren Betätigung des Ventilelements 6 - also bei weiterem Herunterdrücken des Ventilelements 6 - wird der Federabschnitt 21 axial zusammengedrückt und schließlich das Auslaßventil 10 geöffnet. In diesem zusammengedrückten Zustand ist die vom Federabschnitt 21 ausgeübte, in Schließrichtung des Einlaßventils 9 wirkende Federkraft dann ausreichend hoch, um das Einlaßventil 9 gegen den im Behälter 4 herrschenden Druck geschlossen zu halten.In the illustrated example, the inlet valve 9 seals at least substantially axially by the sealing element 14 comes to rest on actuation of the valve element 6 at a suitable, preferably conical shoulder region 16 or other valve seat of the valve housing 7, whereby the inlet valve 9 closes. In the course of the further actuation of the valve element 6 - ie upon further depression of the valve element 6 - the spring portion 21 is axially compressed and finally the exhaust valve 10 is opened. In this compressed state, the force exerted by the spring portion 21, acting in the closing direction of the intake valve 9 spring force is then sufficiently high to keep the inlet valve 9 against the pressure prevailing in the container 4 closed.

Der Federabschnitt 21 gestattet eine verbesserte Abdichtung zwischen dem Dichtungselement 14 und dem Ventilgehäuse 7 bzw. einem Ventilsitz, da sich das Dichtungselement 14 optimal gleichmäßig an den Ventilsitz anlegen kann, insbesondere wobei radiale und axiale Toleranzen sowie ein Verkippen kompensiert bzw. toleriert werden können.The spring section 21 permits an improved sealing between the sealing element 14 and the valve housing 7 or a valve seat, since the sealing element 14 can rest optimally uniformly on the valve seat, In particular, wherein radial and axial tolerances and tilting can be compensated or tolerated.

Das Auslaßventil 10 weist beim Darstellungsbeispiel ein separates Dichtungselement 18 auf, das insbesondere ringförmig ausgebildet ist und vom Ventilgehäuse 7 gegen einen Ringabschnitt des Deckels 5 dichtend gehalten ist. Das separate Dichtungselement 18 dichtet radial zu einem Schaftabschnitt des Ventilelements 6 bzw. Anschlußstücks 8 ab. Im dargestellten, unbetätigten Zustand ist das Auslaßventil 10 geschlossen und kann dementsprechend keine Flüssigkeit 3 aus dem Dosierraum 11 abgabeseitig austreten.The outlet valve 10 has in the illustrated example, a separate sealing element 18, which is in particular annular and is held by the valve housing 7 against a ring portion of the lid 5 sealing. The separate sealing element 18 seals radially to a shaft portion of the valve element 6 or fitting 8 from. In the illustrated, unactuated state, the outlet valve 10 is closed and accordingly no liquid 3 can emerge from the dosing chamber 11 on the discharge side.

Beim Betätigen des Ventilelements 6 wird das Ventilelement 6 bzw. das Anschlußstück 8 derart axial verschoben, daß ein radialer Durchlaßkanal 19 an dem separaten Dichtungselement 18 vorbei in das Innere des Ventilgehäuses 7 bewegt, also zum Dosierraum 11 hin freigegeben wird (diese Stellung ist nicht dargestellt). So wird das Auslaßventil 10 geöffnet, und Flüssigkeit 3 kann aus dem Dosierraum 11 durch den Durchlaßkanal 19 in eine axiale Aussparung 20 und durch diese aus dem Anschlußstück 8 hinaus in den nicht dargestellten Sprühkopf o. dgl. ausströmen.When the valve element 6 is actuated, the valve element 6 or the connecting piece 8 is displaced axially in such a way that a radial passage 19 moves past the separate sealing element 18 into the interior of the valve housing 7, ie is released towards the metering chamber 11 (this position is not shown) ). Thus, the outlet valve 10 is opened, and liquid 3 can flow out of the metering chamber 11 through the passage 19 in an axial recess 20 and through this from the connector 8 also in the spray head o. The like. Not shown.

Bedarfsweise kann das angespritzte oder ggf. auch eingespritzte Dichtungselement 14 auch für sonstige Ventile - also unabhängig von dem vorliegenden Dosierventil 2 - für derartige oder ähnliche Vorrichtungen 1 zur Abgabe und insbesondere Zerstäubung von kosmetischen Flüssigkeiten 3 eingesetzt werden.If desired, the molded or possibly also injected sealing element 14 can also be used for other valves - that is to say independently of the present metering valve 2 - for such or similar devices 1 for dispensing and, in particular, atomising cosmetic liquids 3.

Generell sind die vorschlagsgemäße Vorrichtung 1 und das vorschlagsgemäße Dosierventil 2 für jegliche Art von kosmetischen Flüssigkeiten 3 einsetzbar, wie bereits oben erläutert. Besonders geeignet ist jedoch die Verwendung eines derartigen oder ähnlichen Dosierventils 2 zur dosierten Abgabe einer kosmetischen Flüssigkeit 3, die Partikel enthält, wobei im Dosierraum 11 des Dosierventils 2 verteilte Vorsprünge zur temporären Ablagerung der Partikel verwendet werden, um einem bodenseitigen Absetzen der Partikel und insbesondere Zusetzen des Einlaßventils 9 des Dosierventils 2 entgegenzuwirken, und die Partikel von der Flüssigkeit 3 bei der Abgabe wieder mit ausgetragen werden. In der Gebrauchslage des Dosierventils 2 bzw. Behälters 1 sind die Vorsprünge vorzugsweise in vertikaler Richtung verteilt oder beabstandet angeordnet und besonders bevorzugt durch die Windungen der Rückstellfeder 12 und/oder sonstige Ausnehmungen, Einbuchtungen, Kanten o. dgl. vom Ventilelement 6 und/oder Ventilgehäuse 7 im Dosierraum 11 gebildet.In general, the proposed device 1 and the proposed metering valve 2 can be used for any type of cosmetic liquid 3, as already explained above. Particularly suitable, however, is the use of such or similar metering valve 2 for the metered delivery of a cosmetic liquid 3 containing particles, wherein in the metering chamber 11 of the metering valve 2 distributed projections for temporary deposition of the particles are used to a bottom-side settling of the particles and in particular clogging counteract the intake valve 9 of the metering valve 2, and the particles are discharged from the liquid 3 again during the delivery. In the position of use of the metering valve 2 or container 1 are the Projections preferably distributed in the vertical direction or arranged spaced and more preferably by the turns of the return spring 12 and / or other recesses, indentations, edges o. The like. Formed by the valve element 6 and / or valve housing 7 in the dosing 11.

Bei der Abgabe der Flüssigkeit 2 - also bei Erreichen des betätigten Zustands des Dosierventils 2 - werden dann die auf den Vorsprüngen abgesetzten Partikel von der ausströmenden Flüssigkeit 3 mitgerissen und dadurch zumindest weitgehend gleichmäßig in der Flüssigkeit 3, insbesondere beim anschließenden Versprühen, verteilt.When the liquid 2 is dispensed - ie when the actuated state of the metering valve 2 is reached - the particles deposited on the projections are then entrained by the outflowing liquid 3 and thereby distributed at least substantially evenly in the liquid 3, in particular during the subsequent spraying.
