- the first material and the second material are different, ie differ in particular with regard to their composition and / or properties.
- other constructions are possible in which the same or the same material can be used for the first material and the second material.
- a material pairing is selected for the first material and the second material, so that the two materials are preferably firmly connected to each other directly by spraying.

- the two materials are basically injected into the same injection mold almost simultaneously.
- the desired solid compound is achieved.
- no further measures for connecting the two materials or components here of the actuating element 15 and the valve element 12
- other measures such as pressing, clamping, welding or the like can be used in principle.

Die vorliegende Erfindung betrifft einen Abgabekopf für ein vorzugsweise kosmetisches Produkt gemäß dem Oberbegriff des Anspruchs 1 sowie eine Abgabevorrichtung mit einem Abgabekopf gemäß des Anspruchs 1.The present invention relates to a dispensing head for a preferably cosmetic product according to the preamble of
Die vorliegende Erfindung betrifft einen Abgabekopf, der vorzugsweise an einem Behälter bzw. dessen Abgabeventil oder an einer handbetätigten Pumpe angebracht oder anbringbar ist. Der Abgabekopf dient vorzugsweise der nicht-sprühenden Aus- bzw. Abgabe eines vorzugsweise kosmetischen Produkts.The present invention relates to a dispensing head, which is preferably attached or attachable to a container or its dispensing valve or to a hand-operated pump. The dispensing head preferably serves for non-spraying dispensing or dispensing of a preferably cosmetic product.
Unter dem Begriff "Produkt" sind generell Flüssigkeiten und insbesondere auch Suspensionen und sonstige Fluide, ggf. mit Gasphasen, zu verstehen. Das Produkt kann als Paste, Strahl oder Nebel oder in sonstiger Weise, beispielsweise als Schaum oder Gel, ausgegeben werden.The term "product" generally liquids and especially suspensions and other fluids, possibly with gas phases to understand. The product may be dispensed as a paste, jet or mist or otherwise, for example as a foam or gel.
Vorzugsweise wird der Abgabekopf für ein kosmetisches Produkt eingesetzt. Unter dem Begriff "kosmetisches Produkt" sind in einem engeren Sinn Kosmetika, Haarspray, Haarlack, Deodorant, Rasierschaum, Farbspray, Sonnen- oder Hautpflegemittel, generell Mittel zur Schönheitspflege, o. dgl. zu verstehen. Vorzugsweise werden in einem weiteren Sinn aber auch sonstige Körper- oder Haarpflegeprodukte umfaßt.Preferably, the dispensing head is used for a cosmetic product. The term "cosmetic product" in a narrower sense cosmetics, hair spray, hair lacquer, deodorant, shaving cream, paint spray, sunscreen or skin care products, generally means for beauty care, o. The like. To understand. Preferably, however, other body or hair care products are included in a broader sense.
Beispielsweise kann es sich bei dem Produkt aber auch um Reinigungsmittel oder Schmiermittel oder sonstige Produkte, beispielsweise Luftverbesserer, und insbesondere auch um andere technische Produkte und Fluide, wie Rostlöser o. dgl., handeln. Nachfolgend wird jedoch aus Vereinfachungsgründen und aufgrund des Nutzungsschwerpunkts oft nur von kosmetischem Produkt gesprochen.For example, the product may also be detergents or lubricants or other products, for example air fresheners, and in particular also other technical products and fluids, such as rust remover or the like. However, for simplification reasons and because of the focus of use, the following is often only spoken of cosmetic product.
Bei heutigen Abgabeköpfen zur Abgabe von insbesondere aufschäumenden oder aufgeschäumten Produkten, wie Rasierschaum, oder bei Spenderpumpen besteht häufig das Problem, daß das Produkt nach Beendigung der eigentlichen Abgabe nachträglich noch austritt, insbesondere nachschäumt oder nachtropft. Dieses Problem ist besonders bei Rasierschaum o. dgl. eklatant, tritt jedoch auch bei nicht aufgeschäumten bzw. nicht aufschäumenden Produkten auf und kann insbesondere zu unerwünschten Verschmutzungen der Abgabeköpfe führen.In today's dispensing heads for dispensing particular foaming or foamed products, such as shaving cream, or donor pumps, there is often the problem that the product exits after completion of the actual delivery later, especially nachschäumt or drips. This problem is particularly blatant with shaving o. The like., But also occurs non-foamed or non-intumescent products and may in particular lead to undesirable contamination of the dispensing heads.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Abgabekopf und eine Abgabevorrichtung mit einem Abgabekopf anzugeben, wobei ein einfacher und kostengünstiger Aufbau und/oder ein optimiertes definiertes Öffnen bzw. Schließen des Auslaßventils ermöglicht wird bzw. werden.The present invention has for its object to provide a dispensing head and a dispensing device with a dispensing head, wherein a simple and inexpensive construction and / or an optimized defined opening or closing of the exhaust valve is or will be possible.
Die obige Aufgabe wird durch einen Abgabekopf gemäß Anspruch 1 oder durch eine Abgabevorrichtung gemäß Anspruch 15 gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.The above object is achieved by a dispensing head according to
Gemäß einer anderen, auch unabhängig realisierbaren Idee ist das Ventilelement in der Schließstellung zumindest im wesentlichen nur in Richtung zu einer Schwenkachse des Betätigungselements hin gegen eine Auslaßöffnung des Abgabekopfs bzw. Auslaßkanals vorgespannt. Dies gestattet bei einfachem und kostengünstigem Aufbau insbesondere ein sehr definiertes und weitgehend kraftfreies Schließen des Auslaßventils.According to another, independently realizable idea, the valve element is biased in the closed position at least substantially only in the direction towards a pivot axis of the actuating element against an outlet opening of the dispensing head or outlet channel. This allows with a simple and inexpensive construction in particular a very defined and largely force-free closing of the exhaust valve.
Es ist anzumerken, daß das bei der vorliegenden Erfindung unter dem Begriff "Ventilelement" ein Element zu verstehen ist, das eine Auslaßöffnung bei geschlossenem Auslaßventil verschließt und bei geöffnetem Auslaßventil öffnet.It should be noted that in the present invention, the term "valve element" is an element which closes an outlet opening with the outlet valve closed and opens when the outlet valve is open.
Unter dem Begriff "Betätigungselement" ist vorzugsweise ein Element zu verstehen, das manuell unmittelbar betätigbar ist und/oder zur Betätigung des Abgabekopfs betätigt werden muß. Insbesondere erfolgt das Betätigen durch Niederdrücken eines Teils des Betätigungselements.The term "actuating element" is preferably to be understood as meaning an element which is manually operable directly and / or must be actuated to actuate the dispensing head. In particular, the operation is carried out by depressing a part of the actuating element.

Der Abgabekopf 1 weist weiter ein vorzugsweise in das Gehäuseteil 5 eingesetztes und/oder davon gehaltenes oder gebildetes Bauteil 6 auf, das einen Auslaßkanal 7 bildet und an das Abgabeventil 4 anschließbar bzw. angeschlossen ist. Beim Darstellungsbeispiel ist das Bauteil 6 mit einem entsprechenden Anschlußabschnitt 8 zur insbesondere steckbaren Verbindung mit dem Abgabeventil 4 bzw. einem Stutzen 9 des Abgabeventils 4 versehen.The dispensing
Beim Darstellungsbeispiel sind das Gehäuseteil 5 und das Bauteil 6 vorzugsweise einstückig miteinander ausgebildet, insbesondere wobei das Gehäuseteil 5 das Bauteil 6 und damit den Auslaßkanal 7 bzw. Anschlußabschnitt 8 kippbar bzw. niederdrückbar hält.In the illustrated embodiment, the
Vorzugsweise ist das Bauteil 6 zungenartig oder armartig ausgebildet und/oder auf einer Seite bzw. an einem Ende gehalten.Preferably, the
Der Anschlußabschnitt 8 ist vorzugsweise im Bereich der Mitte des Abgabekopfs 1 bzw. des freien Endes des Bauteils 6 angeordnet.The
Das Bauteil 6 oder Gehäuseteil 5 bildet vorzugsweise einen federnd nachgiebigen, beispielsweise kippbaren und/oder zungenartigen Bereich bzw. Abschnitt, so daß dieser mit dem Anschlußabschnitt 8 zum Abgabeventil 4 hin verlagerbar und dadurch das (behälterseitige) Abgabeventil 4 öffenbar ist.The
Die Abgabekopf 1 weist beim Darstellungsbeispiel ein Auslaßventil 10 auf, das insbesondere dem Auslaßkanal 7 und/oder einem Abgabeende 11 des Abgabekopfs 1 zugeordnet ist.In the illustrated embodiment, the dispensing
Besonders bevorzugt weist das Auslaßventil 10 ein Ventilelement 12 zum Öffnen und Schließen des Auslaßventils 10 bzw. des Auslaßkanals 7 auf. Besonders bevorzugt schließt sich keine Düse, kein weiterer Kanal o. dgl. an das Auslaßventil 10 bzw. dessen Ventilelement 12 bzw. an das Abgabeende 11 oder eine Auslaßöffnung 13 des Auslaßkanals 7 an. Vielmehr öffnen sich diese vorzugsweise "ins Freie". So kann die Produkt 2 nach Austritt aus dem Auslaßventil 10 von einem nicht dargestellten Benutzer vorzugsweise unmittelbar aufgenommen bzw. benutzt werden. Beim Darstellungsbeispiel überdeckt das Ventilelement 12 die Auslaßöffnung 13 des Auslaßkanals 7 in der gezeigten Schließstellung vorzugsweise nur von außen.The
Die Abgabeöffnung 13 des Auslaßkanals 7 endet vorzugsweise in oder an einer Seitenwand 14 des Abgabekopfs 1 bzw. Gehäuseteils 5.The
Der Abgabekopf 1 weist ein Betätigungselement 15 auf, das beim Darstellungsbeispiel als separates Teil ausgeführt ist. Jedoch sind auch andere konstruktive Lösungen möglich, beispielsweise eine einstückige Ausbildung.The dispensing
Das Öffnen des Abgabeventils 4 erfolgt vorzugsweise durch Niederdrücken und/oder Kippen des oben genannten, federnd nachgiebigen Bereich bzw. Bauteils 6 bzw. des Anschlußabschnitts 8 bzw. des Betätigungselements 15. Beispielsweise kann das Betätigungselement 15 hierzu über einen Vorsprung oder Betätigungsabschnitt 16 auf das Bauteil 6 einwirken.The opening of the dispensing
Das Betätigungselement 15 ist vorzugsweise schwenkbar bzw. kippbar, insbesondere relativ zum Gehäuseteil 5, Bauteil 6 und/oder Auslaßkanal 7.
Vorzugsweise liegt die Schwenkachse 17 im wesentlichen zwischen dem Anschlußabschnitt 8 einerseits und dem Abgabeende 11 (Auslaß) bzw. der Auslaßöffnung 13 andererseits.Preferably, the
Grundsätzlich kann der Schwenkbewegung des Betätigungselements 15 bei Betätigung des Abgabekopfs 1 bzw. unmittelbarer manueller Betätigung des Betätigungselements 15 auf eine andere Bewegung überlagert sein. Alternativ oder zusätzlich kann das Betätigungselement 15 auch translatorisch und/oder rotatorisch, beispielsweise um eine Achse senkrecht oder windschief zur Schwenkachse 17, bewegbar bzw. betätigbar sein.Basically, the pivoting movement of the
Das Ventilelement 12 ist vorzugsweise ausschließlich vom Betätigungselement 15 geführt bzw. gehalten.The
Vorzugsweise ist das Ventilelement 12 fest mit dem Betätigungselement 15 verbunden.Preferably, the
Insbesondere ist das Ventilelement 12 nur zusammen mit dem Betätigungselement 15 bewegbar.In particular, the
Das Ventilelement 12 besteht vorzugsweise aus einem elastischen Material bzw. Kunststoff.The
Vorzugsweise ist das Ventilelement 12 an das Betätigungselement 15 angespritzt oder umgekehrt. Dies erfolgt insbesondere bevorzugt durch sogenannte "Bi-Injection". Hierbei wird ein erstes Bauteil, wie das Betätigungselement 15, zunächst in einer Form gespritzt und anschließend bzw. (fast) gleichzeitig das zweite Bauteil, wie das Ventilelement 12, in der gleichen Spritzform unmittelbar gegen das erste Bauteil gespritzt. Jedoch sind auch andere Arten der Herstellung möglich.Preferably, the
Erfindungsgemäß ist das Ventilelement 12 kalottenartig ausgebildet.According to the invention, the
Das Ventilelement 12 verschließt die Auslaßöffnung 13 des Auslaßkanals 7 nur von außen her, insbesondere mit dem vorgenannten Verschlußabschnitt 20.The
Besonders bevorzugt ist das Ventilelement 12 an einem freien Ende bzw. Rand 21 des Betätigungselements 15 angeordnet.Particularly preferably, the
Das Betätigungselement 15 ist vorzugsweise zur unmittelbaren manuellen Betätigung ausgebildet und weist hierzu vorzugsweise einen Griff- bzw. Niederdrückabschnitt 22 auf. Der Griffabschnitt 22 ist vorzugsweise bezüglich des Ventilelements 12 bzw. Auslaßventils 10 auf der anderen Seite der Schwenkachse 17 angeordnet.The
Besonders bevorzugt ist der Abstand des Griffabschnitts 22 von der Schwenkachse größer als der Abstand des Ventilelements 12 von der Schwenkachse 17, vorzugsweise um den Faktor 1,5 oder mehr, beim Darstellungsbeispiel insbesondere etwa um den Faktor 2. Dies führt zu einer vorteilhaften Übersetzung.Particularly preferably, the distance of the
Im dargestellten, geschlossenen Zustand befindet sich das Betätigungselement 15 in der nicht gekippten bzw. oberen Position (Ausgangsposition), so daß das Ventilelement 12 das Auslaßventil 10 geschlossen hält, wie in
Das Betätigungselement 15 ist um die vorzugsweise horizontal bzw. bei der Darstellung gemäß
Durch Niederdrücken des Betätigungselements 15 bzw. Griffabschnitts 22 (in den
Bei Betätigung des Betätigungselements 15 wird das Auslaßventil 10 zwangsweise geöffnet, insbesondere selbsttätig unabhängig vom Produktdruck, da das Ventilelement 12 von der Auslaßöffnung 13 - insbesondere zumindest im wesentlichen quer bzw. senkrecht zur Hauptauslaßrichtung - abgerückt wird. Das Ventilelement 12 wird vorzugsweise ausschließlich von dem Betätigungselement 15 geführt. Das Ventilelement 12 wird vorzugsweise nur auf einer Kreisbahn bewegt, wie in
Bei geöffnetem Abgabeventil 4 kann dann das im Reservoir bzw. Behälter 3 vorzugsweise unter Druck stehende Produkt 2 beispielsweise über eine Steigleitung 23 (
Die Produkt 2 kann dann durch das geöffnete Auslaßventil 10 nach außen bzw. ins Freie entweichen und besonders bevorzugt aufschäumen bzw. weiter aufschäumen oder ein Gel oder ein sonstiges Produkt bilden oder in flüssiger, pastöser oder sonstiger Form ausgegeben werden.The
Das Abgabeventil 4 schließt bei Loslassen des Betätigungselements 15 vorzugsweise wieder selbsttätig. Beim Darstellungsbeispiel erfolgt die Rückstellung des Bauteils 6 bzw. Anschlußabschnitts 8 vorzugsweise ausschließlich durch Federkräfte des federnden Abschnitts und/oder durch das Abgabeventil 4.The dispensing
Zusätzlich oder alternativ kann jedoch beispielsweise auch eine nicht dargestellt Rückstell- oder Schließfeder oder eine sonstige konstruktive Lösung eingesetzt werden.In addition or as an alternative, however, it is also possible to use, for example, an unillustrated return or closing spring or another constructive solution.
Bedarfsweise kann es sich bei dem Abgabeventil 4 beispielsweise auch um ein Dosierventil oder eine sonstige Ventileinrichtung handeln.If necessary, the dispensing
Die Produktabgabe bzw. Schaumerzeugung endet endgültig, wenn das Auslaßventil 10 schließt. Das geschlossene bzw. sich schließende Auslaßventil 10 verhindert, daß im Auslaßkanal 7 befindliches Produkt 2 bzw. befindlicher Schaum der dgl. in unerwünschter Weise noch nachträglich austreten bzw. herausschäumen kann.The product delivery or foaming finally ends when the
Besonders bevorzugt ist das Betätigungselement 15 in seine Ausgangsstellung bzw. die das Auslaßventil 10 schließende Schließstellung vorgespannt. Beim Darstellungsbeispiel ist hierzu ein Federabschnitt 24 vorgesehen, der insbesondere am Bauteil 6 einstückig angeformt bzw. von diesem gebildet ist. Jedoch sind auch andere konstruktive Lösungen möglich.Particularly preferably, the
Die vom Federabschnitt 24 bzw. einer sonstigen Einrichtung auf das Betätigungselement 15 ausgeübte Rückstellkraft ist vorzugsweise kleiner als die zum Niederdrücken des Bauteils 6 bzw. Anschlußabschnitts 8 und insbesondere die zum Öffnen des Abgabeventils 4 erforderliche Kraft. So kann erreicht werden, daß bei Betätigen bzw. Niederdrücken des Betätigungselements 15 bzw. Griffabschnitts 22 zunächst das Ventilelement 12 abgerückt, also das Auslaßventil 10 geöffnet wird, bevor das Abgabeventil 4 öffnet.The restoring force exerted on the
Ein besonderer Vorteil des Auslaßventils 10 liegt darin, daß neben der Vermeidung eines nachträglichen Austritts von Produkt 2 auch für den Benutzer eine sehr einfache Reinigung ermöglicht wird, da das Auslaßventil 10 vorzugsweise ein sauberes bzw. leicht zu reinigendes Abgabeende 11 bildet.A particular advantage of the
Beim Darstellungsbeispiel erfolgt die Produktsausgabe vorzugsweise im wesentlichen quer, insbesondere senkrecht, zur Niederdrückrichtung bzw. Öffnungsrichtung des Abgabeventils 4 und/oder zumindest im wesentlichen horizontal oder quer zur Längsrichtung des Behälters 3.In the illustrated embodiment, the product dispensing preferably takes place substantially transversely, in particular perpendicular, to the depression direction or opening direction of the dispensing
Es ist zu erwähnen, daß sich an das Abgabeende 11 vorzugsweise keine weitere, die Produktsabgabe formende Einrichtung, wie eine Düse, ein Kanal oder dgl., anschließt. Dies schließt jedoch nicht aus, daß beispielsweise eine schalenartige Erweiterung, gehäuseseitige Vertiefung o. dgl., in die das Abgabeende 11 mündet, vorgesehen sein kann.It is to be noted that preferably no further product-discharge-forming means, such as a nozzle, a channel or the like, adjoins the
Beim Darstellungsbeispiel ist das Betätigungselement 15 vorzugsweise als separates Teil ausgebildet, das insbesondere aufgesetzt, aufgesteckt, aufgeklemmt oder aufgerastet ist, insbesondere an den Halteabschnitten 19 (
Vorzugsweise ist das Betätigungselement 15 mit seinen Lagerabschnitten bzw. Lageraugen 18 oder auf sonstige Weise auf beiden Seiten des Auslaßventils 10 bzw. Ventilelements 12 gelagert bzw. abgestützt und/oder auf die Halteabschnitte 19 aufrastbar bzw. aufgerastet.Preferably, the
Es sind aber auch andere konstruktive Lösungen möglich. Insbesondere kann das Betätigungselement 15 grundsätzlich auch auf sonstige Weise gelagert, elastisch verformbar und/oder an das Gehäuseteil 5 bzw. Bauteil 6 angeformt sein.But there are also other constructive solutions possible. In particular, the
Nachfolgend wird eine zweite Ausfuhrungsform des vorschlagsgemäßen Abgabekopfs 1 anhand der weiteren Figuren erläutert, wobei sich die folgende Beschreibung auf wesentliche Unterschiede oder neue Aspekte beschränkt. Die bisherigen Ausführungen und Erläuterungen gelten insbesondere entsprechend oder ergänzend.Hereinafter, a second embodiment of the proposed
Bei der zweiten Ausführungsform ist das Ventilelement 12 vorzugsweise auf einer Innenseite des Rands 21 des Betätigungselements 15 angeordnet.In the second embodiment, the
Bei der zweiten Ausführungsform ist der Verschlußabschnitt 20 des Ventilelements 12 vorzugsweise gewölbt bzw. kalottenartig ausgebildet und/oder so angepaßt, daß er sich zumindest teilweise in die Abgabeöffnung 13 bzw. den sich anschließenden Auslaßkanal 7 von der Auslaßseite her in der Schließstellung hinein erstrecken kann.In the second embodiment, the
Besonders bevorzugt ist das Betätigungselement 15 bzw. Auslaßventil 10 rastend in der Schließstellung bzw. unbetätigten Stellung gehalten. Dies kann insbesondere durch den vorgenannten Eingriff des Ventilelements 12 bzw. dessen Verschlußabschnitts 20 in die Auslaßöffnung 13 bzw. den Auslaßkanal 7 realisiert werden. Jedoch sind hier auch andere konstruktive Lösungen möglich.Particularly preferably, the
Bei der zweiten Ausführungsform ist das Ventilelement 12 in der Schließstellung vorzugsweise zumindest im wesentlichen axial bzw. nur zur Schwenkachse 17 hin gegen die Auslaßöffnung 13 vorgespannt. So wird ein quasi kraftfreies und/oder definiertes Schließen des Auslaßventils 10 ermöglicht. Insbesondere ist die Betätigung des Betätigungselements 15 zumindest weitgehend von der Schließkraft entkoppelt. Dies gestattet eine möglichst einfache Betätigung bei hoher Dichtwirkung bzw. Schließkraft.In the second embodiment, the
Besonders bevorzugt liegen die Schwenkachse 17 und der letzte Abschnitt des Auslaßkanals 7, der sich zur Auslaßöffnung 13 hin erstreckt, zumindest im wesentlichen in einer Ebene. Alternativ oder zusätzlich kreuzt die Schwenkachse 17 vorzugsweise eine Mittelsenkrechte der Auslaßöffnung 13 oder führt nah daran vorbei.Particularly preferably, the
Die nachfolgende Ausführungsformen beziehen sich insbesondere auf alle Ausführungsformen sowie generell auf die Erfindung.The following embodiments relate in particular to all embodiments and in general to the invention.
Das Gehäuseteil 5, Bauteil 6, Ventilelement 12 ist bzw. sind vorzugsweise spritzgegossen bzw. aus Kunststoff hergestellt.The
Das Betätigungselement 15 ist aus einem ersten Material, insbesondere einem relativ starren Kunststoffmaterial, hergesteht. Bevorzugt wird ein Polyolephin, insbesondere PP (Polypropylen) oder PE (Polyethylen) eingesetzt.The
Das Ventilelement 12 ist aus einem zweiten Material hergestellt. Insbesondere handelt es sich bei dem zweiten Material um ein Elastomer und/oder einen Thermoplasten. Bevorzugt wird TPE (thermoplastisches Elastomer) oder TPV o. dgl. eingesetzt. Insbesondere handelt es sich um ein flexibles Material. Das zweite Material ist insbesondere flexibel oder weicher als das erste Material. Dies ist insbesondere bei den dargestellten Ausrührungsformen wünschenswert, da das daraus gebildete Ventilelement 12 eine gewisse elastische Verformbarkeit und/oder Flexibilität im Gegensatz zu dem Betätigungselement 15 aufweisen soll.The
Dementsprechend sind das erste Material und das zweite Material unterschiedlich, unterscheiden sich also insbesondere hinsichtlich ihrer Zusammensetzung und/oder Eigenschaften. Jedoch sind grundsätzlich auch andere Konstruktionen möglich, bei denen für das erste Material und das zweite Material das gleiche bzw. dasselbe Material verwendet werden kann.Accordingly, the first material and the second material are different, ie differ in particular with regard to their composition and / or properties. However, in principle, other constructions are possible in which the same or the same material can be used for the first material and the second material.
Vorzugsweise wird für das erste Material und das zweite Material eine Materialpaarung gewählt, so daß die beiden Materialien vorzugsweise direkt durch Spritzen miteinander fest verbindbar sind. Besonders bevorzugt ist eine derartige feste Verbindung der beiden Materialien ohne Vorbehandlung, Haftvermittler, Bearbeitung o. dgl. erreichbar.Preferably, a material pairing is selected for the first material and the second material, so that the two materials are preferably firmly connected to each other directly by spraying. Such a solid compound of the two materials without pretreatment, adhesion promoter, processing or the like is particularly preferably attainable.
Besonders bevorzugt erfolgt das Anspritzen durch die sogenannte "BI-Injection", bei der zunächst ein Material (das erste Material) in eine Spritzform gespritzt und dann das andere Material (das zweite Material) insbesondere in derselben Spritzform gegen das zuvor gespritzte Material gespritzt wird. Jedoch ist es grundsätzlich auch möglich, daß die beiden Materialien grundsätzlich fast gleichzeitig in dieselbe Spritzform gespritzt werden.Injection molding is particularly preferably carried out by the so-called "BI injection" in which first a material (the first material) is injected into an injection mold and then the other material (the second material) is sprayed, in particular in the same injection mold, against the previously sprayed material. However, it is also possible in principle that the two materials are basically injected into the same injection mold almost simultaneously.
Durch das Spritzen der beiden Materialien gegeneinander wird die gewünschte feste Verbindung erreicht. Vorzugsweise sind keine weiteren Maßnahmen zur Verbindung der beiden Materialien bzw. Bauteile (hier des Betätigungselements 15 und des Ventilelements 12) erforderlich, um die gewünschte Festigkeit, chemische Verbindung, chemische Beständigkeit und/oder Dichtigkeit zu erreichen. Jedoch können grundsätzlich auch ergänzende oder alternativ sonstige Maßnahmen, wie ein Verpressen, Einklemmen, Verschweißen o. dgl. eingesetzt werden.By spraying the two materials against each other, the desired solid compound is achieved. Preferably, no further measures for connecting the two materials or components (here of the
Besonders bevorzugt bildet das Betätigungselement 15 eine obere Abdeckung des Abgabekopfs 1 und/oder überdeckt das Bauteil 6 und ggf. auch das Gehäuseteil 12 zumindest im wesentlichen vollständig. Besonders bevorzugt ist das Betätigungselement 15 zumindest im wesentlichen deckelartig bzw. kappenartig ausgebildet.Particularly preferably, the
Besonders bevorzugt erstreckt sich das Betätigungselement 15 mit seinem Rand 21 in den Bereich der Seitenwandung des vorzugsweise zumindest im wesentlichen zylindrischen Gehäuseteils 5. Jedoch sind auch andere konstruktive Lösungen möglich.Particularly preferably, the
Die vorgeschlagenen Ausführungsformen gestatten ein optimales Öffnen des Auslaßventils 10 insbesondere auf den vollen Querschnitt der Auslaßöffnung 13. So können ein optimiertes Ausströmverhalten und eine optimierte Restentleerung erreicht werden.The proposed embodiments allow an optimal opening of the
