Die vorliegende Erfindung betrifft eine Ab gäbe Vorrichtung für ein vorzugsweise kosmetisches Produkt gemäß dem Oberbegriff einer der unabhängigen Ansprü- che.The present invention relates to a Ab gabe device for a preferably cosmetic product according to the preamble of one of the independent claims che.
Die Abgabevorrichtung dient vorzugsweise einer nicht- sprühenden Aus- bzw. Abgabe eines vorzugsweise kosmetischen Produkts. Jedoch kann auch eine sprühende Ausgabe vorgesehen sein.The dispensing device preferably serves for non-spraying dispensing or dispensing of a preferably cosmetic product. However, a spraying output may also be provided.
Unter dem Begriff "kosmetisches Produkt" sind in einem engeren Sinn Kosmetika, Haarspray, Haarlack, ein Deodorant, ein Schaum, insbesondere Rasierschaum, ein Gel, ein Farbspray, ein Sonnen- oder Hautpflegemittel o. dgl. oder sonstige kosmetische Flüssigkeiten, Fluide, Pasten, Lotionen, Emulsionen oder dgl. zu verstehen. Vorzugsweise werden in einem weiteren Sinn aber auch sonstige Körperpflegeprodukte, Reinigungsprodukte, o. dgl., und auch Suspensionen und Fluide, ggf. auch mit Gasphasen, umfaßt. Weiter können als sonstige Flüssigkeiten und Fluide, 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 kosmetischem Produkt gesprochen. Besonders bevorzugt wird die vorschlagsgemäße Abgabevorrichtung zur Lagerung und Ausgabe von einem Gel, insbesondere Rasiergel, oder einer Paste, insbesondere Zahnpasta, o. dgl. verwendet.In a narrower sense, the term "cosmetic product" includes cosmetics, hair spray, hair lacquer, a deodorant, a foam, in particular shaving cream, a gel, a paint spray, a sunscreen or skin care agent or the like or other cosmetic fluids, fluids, pastes , Lotions, emulsions or the like.

BESTÄTIGUNGSKOPSE stellt. Problematisch ist das Diffusionsverhalten. Polypropylen ist nämlich nicht diffusionsdicht, insbesondere nicht gegenüber Sauerstoff. Dementsprechend kann eine längere Lagerung problematisch sein, da durch das Ventilgehäuse hindurch Sauerstoff in einem Ventilraum diffundieren und insbesondere bei einem kosmetischen Produkt zu unerwünschten Reaktionen fuhren kann. Um diesem unerwünschten Effekt entgegenzuwirken, ist eine sehr dickwandige Ausbildung des Ventilgehäuses erforderlich. Dies ist jedoch hinsichtlich der Materialkosten und Baugröße nachteilig.BESTÄTIGUNGSKOPSE provides. The problem is the diffusion behavior. In fact, polypropylene is not diffusion-tight, especially not oxygen. Accordingly, prolonged storage can be problematic because oxygen can diffuse through the valve housing in a valve space and can lead to undesirable reactions, especially in the case of a cosmetic product. To counteract this undesirable effect, a very thick-walled construction of the valve housing is required. However, this is disadvantageous in terms of material costs and size.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine verbesserte Abgabevorrichtung anzugeben, die eine gegenüber dem Stand der Technik vereinfachte und/oder kostengünstigere Herstellung ermöglicht und/oder die universell - insbesondere auch mit anderen Materialien - einsetzbar ist.The present invention has for its object to provide an improved dispensing device, which allows a comparison with the prior art simplified and / or cost-effective production and / or the universal - especially with other materials - can be used.
Die obige Aufgabe wird durch eine Abgabevorrichtung gemäß einem der unabhängigen Ansprüche gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.The above object is achieved by a dispenser according to one of the independent claims. Advantageous developments are the subject of the dependent claims.
Gemäß einem ersten Aspekt der vorliegenden Erfindung ist der Innenbehälter mit dem Ventilgehäuse ultraschallverschweißt. Des weiteren wird vorzugsweise Polyethylen oder Polyamid für das Ventilgehäuse und die innere Schicht des Innenbehälters verwendet. So wird eine vereinfachte und kostengünstige Herstellung ermöglicht, insbesondere kann das Ventilgehäuse bei mindestens gleichguter oder gar besserer Diffusionsdichtigkeit dünner ausgebildet werden.According to a first aspect of the present invention, the inner container is ultrasonically welded to the valve housing. Furthermore, polyethylene or polyamide is preferably used for the valve housing and the inner layer of the inner container. Thus, a simplified and cost-effective production is made possible, in particular, the valve housing can be made thinner at least equally good or even better diffusion tightness.
Gemäß einem zweiten, auch unabhängig realisierbaren Aspekt der vorliegenden Erfindung ist am Ventilgehäuse mindestens ein Schweißwulst vor dem Verschweißen mit dem Innenbehälter angeordnet oder gebildet, der beim Verschweißen vom Innenbehälter überdeckt wird. Dies ist wiederum einer einfachen und kostengünstigen Herstellung, insbesondere dem Verschweißen des Innenbehälters mit dem Ventilgehäuse durch Ultraschall, zuträglich.According to a second, independently realizable aspect of the present invention, at least one welding bead is arranged or formed on the valve housing prior to welding to the inner container, which is covered during welding by the inner container. This in turn is a simple and cost-effective production, in particular the welding of the inner container with the valve housing by ultrasound, conducive.
Gemäß einem dritten, ebenfalls unabhängig realisierbaren Aspekt der vorliegenden Erfindung ist der Innenbehälter mit dem Ventilgehäuse über eine Länge von mindestens 70 % oder mehr der Längserstreckung des Ventilgehäuses ver- schweißt. Alternativ oder zusätzlich ist der Innenbehälter mit dem Ventilgehäuse bis zu einer dem Innenbehälter zugewandten oder benachbarten Seite eines Tellers des Ventils, der das Ventilgehäuse mit einem zugeordneten Außenbehälter verbindet, verschweißt oder verbunden. Dies ist der Erhöhung der Diffusions- dichtigkeit zuträglich und gestattet insbesondere eine geringere Wanddicke des Ventilgehäuses bei ausreichender oder gar verbesserter Diffusionsdichtigkeit und damit eine einfachere und kostengünstigere Herstellung.According to a third, likewise independently realizable aspect of the present invention, the inner container with the valve housing is over a length of at least 70% or more of the longitudinal extent of the valve housing. welded. Alternatively or additionally, the inner container with the valve housing to a inner container facing or adjacent side of a plate of the valve, which connects the valve housing with an associated outer container, welded or connected. This is conducive to increasing the diffusion density and in particular allows a smaller wall thickness of the valve housing with sufficient or even improved diffusion tightness and thus a simpler and more cost-effective production.

The like. The valve 3 and valve housing 3a preferably ends on the outlet side in the recess 6b. Preferably, a particular annular seal 7 between the bottom of the recess 6b and the end face of the valve housing 3a is arranged to seal the valve housing 3a on the outside of the plate 6 and so to close the outer container 5 gas-tight. However, other constructive solutions are possible.
Der Innenbehälter 4 ist gasdicht mit dem Ventilgehäuse 3 - insbesondere an dem dem Teller 6 abgewandten Endbereich bzw. Einlaßende - verbunden. Dieser Endbereich bzw. dieses Einlaßende ragt insbesondere in das Innere des Außenbehälters 5 und insbesondere in den Innenraum des Innenbehälters 4.The inner container 4 is gas-tight with the valve housing 3 - in particular at the end facing away from the plate 6 and inlet end - connected. This end region or this inlet end projects in particular into the interior of the outer container 5 and in particular into the interior of the inner container 4.
Der Innenbehälter 4 enthält das auszugebende, vorzugsweise kosmetische Produkt 2. Um die Aufnahme des Produkts 2 aus dem Innenbehälter 4 zu erleichtern kann einlaßseitig an das Ventil 3 eine optionale Steigleitung 8, insbesondere ein Schlauch o. dgl., angeschlossen sein. Die Steigleitung 8 ist insbesondere in einen oder auf einen vom Ventilgehäuse 3 a gebildeten, einlaßseitigen Anschlußstutzen o. dgl. gesteckt oder in sonstiger geeigneter Weise mit dem Ventilgehäuse 3a einlaßseitig verbunden bzw. verbindbar.The inner container 4 contains the preferably cosmetic product 2 to be dispensed. In order to facilitate the reception of the product 2 from the inner container 4, an optional riser 8, in particular a hose or the like, may be connected on the inlet side to the valve 3. The riser 8 is in particular in one or on one of the valve housing 3 a formed, inlet side connecting piece o. The like. Plugged or connected in any other suitable manner with the valve housing 3a on the inlet side or connectable.
Der Außenbehälter 5 ist mit einem unter Druck stehenden Gas 9, das in Fig. 1 gepunktet angedeutet ist, befüllt. Bei dem Gas 9 handelt es sich insbesondere um Luft oder ein sonstiges geeignetes Druckgas, gegebenenfalls auch Flüssiggas o. dgl.The outer container 5 is filled with a pressurized gas 9, which is indicated dotted in Fig. 1. The gas 9 is, in particular, air or another suitable compressed gas, if appropriate also liquid gas or the like.
Der in dem Außenbehälter 5 herrschende Gasdruck wirkt außenseitig auf den flexiblen Innenbehälter 4 ein, so daß das Produkt 2 bei geöffnetem Ventil 3 über das Ventil 3 und einen sich eventuell anschließenden Ausgabekopf o. dgl. ausgegeben wird. Bei der Entnahme bzw. Abgabe des Produkts 2 kollabiert der Innenbehälter 4. Der Innenbehälter 4 ist mit dem Ventilgehäuse 3a - wie bereits erwähnt - vorzugsweise gasdicht verbunden, insbesondere verschweißt. Besonders bevorzugt ist der Innenbehälter 4 mit dem Ventilgehäuse 3a ultraschallverschweißt. Dies ermöglicht eine wesentlich energiesparendere, schnellere und/oder kostengünsti- gere Herstellung der Abgabevorrichtung 1 gegenüber der beim Stand der Technik vorgesehenen Wärmeschweißung. Jedoch ist es grundsätzlich auch möglich, den Innenbehälter 4 mit dem Ventilgehäuse 3 auf jede sonstige geeignete Art und Weise, beispielsweise durch sonstiges Schweißen, Klemmen, Anspritzen, Kleben o. dgl. zu verbinden.The prevailing in the outer container 5 gas pressure acts on the outside of the flexible inner container 4, so that the product 2 with the valve open 3 via the valve 3 and a possibly subsequent dispensing head o. The like. Is outputted. When removing or dispensing the product 2, the inner container 4 collapses. The inner container 4 is connected to the valve housing 3a - as already mentioned - preferably gas-tight, in particular welded. Particularly preferably, the inner container 4 is ultrasonically welded to the valve housing 3a. This makes possible a substantially more energy-saving, faster and / or more cost-effective production of the dispensing device 1 compared with the heat welding provided in the prior art. However, in principle it is also possible to connect the inner container 4 to the valve housing 3 in any other suitable manner, for example by means of other welding, clamping, spraying, gluing or the like.
Beim Darstellungsbeispiel weist das Ventil 3 bzw. Ventilgehäuse 3a einen zumindest im wesentlichen rohrförmigen Abschnitt 3 b und insbesondere zwei an gegenüberliegenden Seiten des Abschnitts 3b angeordnete, sich insbesondere radial und längs des rohrförmigen Abschnitts 3b erstreckende Seitenflügel 3c auf. Dies ist insbesondere der perspektivischen Ansicht des Ventils 3 gemäß Fig. 2 und der Unteransicht des Ventils 3 ohne Teller 6 gemäß Fig. 3 zu entnehmen.In the illustrated example, the valve 3 or valve housing 3a has an at least substantially tubular section 3b and in particular two side wings 3c arranged on opposite sides of the section 3b and extending in particular radially and along the tubular section 3b. This is particularly the perspective view of the valve 3 shown in FIG. 2 and the bottom view of the valve 3 without plate 6 as shown in FIG. 3 can be seen.
Die Seitenflügel 3c verjüngen sich vorzugsweise zu ihren freien Kanten hin. Insbesondere laufen die beiden Flügel 3c nach außen hin bzw. radial spitz zu. Dies verhindert oder minimiert eine Zwickelbildung im Bereich der freien Kanten und der sich ausgehend von dem rohrförmigen Bereich 3b an der Kante treffenden Innenbehälterwandungen.The side wings 3c preferably taper towards their free edges. In particular, the two wings 3c run outwardly or radially pointedly. This prevents or minimizes gussing in the area of the free edges and the inner container walls which meet at the edge starting from the tubular area 3b.
Der Innenbehälter 4 ist insbesondere in dem Bereich des vorzugsweise rohrför- migen Abschnitts 3b und der Seitenflügel 3c mit dem Ventilgehäuse 3a verbunden, insbesondere ultraschallverschweißt. Beim Darstellungsbeispiel weist der Innenbehälter 4 vorzugsweise eine obere bzw. im Bereich des Ventils 3 angeordnete Verbindungs- bzw. Schweißnaht 4a auf, die in Fig. 1 durch Schraffierung angedeutet ist und sich beispielsweise über die gesamte Breite des Innenbehälters 4 erstreckt. Vorzugsweise ist in diese Schweißnaht 4a das Ventilgehäuse 3a mit dem rohrförmigen Abschnitt 3b und den Seitenflügeln 3c eingeschweißt. Jedoch sind auch andere konstruktive Lösungen möglich.The inner container 4 is connected, in particular in the area of the preferably tubular section 3b and the side wings 3c, to the valve housing 3a, in particular ultrasonically welded. In the illustrated embodiment, the inner container 4 preferably has an upper or arranged in the region of the valve 3 connecting or welding seam 4a, which is indicated in Fig. 1 by hatching and extends for example over the entire width of the inner container 4. Preferably, in this weld 4a, the valve housing 3a with the tubular portion 3b and the side wings 3c welded. However, other constructive solutions are possible.
Um eine möglichst hohe Diffusionsdichtigkeit des Ventilgehäuses 3a zu errei- chen, also eine mögliche Diffusion des Gases 9 bzw. von Bestandteilen des Ga- ses 9, wie Sauerstoff, durch das Ventilgehäuse 3a hindurch in einen Ventilraum mit dem Produkt 2, wo das Gas 9 bzw. ein Bestandteil davon mit dem Produkt 2 - insbesondere bei längerer Lagerung - reagieren kann, zu minimieren, ist der Innenbehälter 4 mit dem Ventilgehäuse 3a vorzugsweise über eine Länge von mindestens 70 %, insbesondere zu etwa 80 % oder mehr, der Längserstreckung des Ventilgehäuses 3a oder Ventils 3 verbunden bzw. verschweißt, das Ventilgehäuse 3 a also diffusionsdicht abgedeckt.In order to achieve the highest possible diffusion-tightness of the valve housing 3a, ie a possible diffusion of the gas 9 or of components of the gas ses 9, such as oxygen, through the valve housing 3a through into a valve chamber with the product 2, where the gas 9 or a part thereof with the product 2 - especially during prolonged storage - can react to minimize, the inner container 4 with the Valve housing 3a preferably over a length of at least 70%, in particular about 80% or more, the longitudinal extension of the valve housing 3a or valve 3 connected or welded, the valve housing 3 a so covered diffusion-tight.
Alternativ oder zusätzlich ist der Innenbehälter 4 mit dem Ventilgehäuse 3a vor- zugsweise bis zu der dem Innenbehälter 4 zugewandten oder benachbarten Seite 6a des Tellers 6 verbunden bzw. verschweißt, um die Diffusionsdichtigkeit des Ventilgehäuses 3a zu erhöhen.Alternatively or additionally, the inner container 4 is connected to the valve housing 3a, preferably up to the inner container 4 facing or adjacent side 6a of the plate 6 or welded to increase the diffusion tightness of the valve housing 3a.
Aufgrund der Erhöhung der Diffusionsdichtigkeit ist es grundsätzlich möglich, die Wandungsdicke des Ventilgehäuses 3a zu verringern. Dies gestattet eine kostengünstigere Herstellung.Due to the increase in the diffusion-tightness, it is basically possible to reduce the wall thickness of the valve housing 3a. This allows a cheaper production.
Gemäß einem weiteren, auch unabhängigen Aspekt der vorliegenden Erfindung ist am Ventilgehäuse 3 a vorzugsweise mindestens ein Schweißwulst 10 vor dem Verschweißen mit dem Innenbehälter 4 angeordnet oder gebildet, insbesondere angeformt. Der Schweißwulst 10 wird beim Verschweißen vom Innenbehälter 4 überdeckt. Der Schweißwulst 10 ist insbesondere stegartig oder rippenartig und/oder durchgängig bzw. fortlaufend ausgebildet. Der Schweißwulst 10 ist im Querschnitt beispielsweise im wesentlichen dreieckig, quadratisch, rechteckig, trapezförmig oder konvex bzw. gewölbt ausgebildet.According to a further, independent aspect of the present invention, at least one welding bead 10 is preferably arranged or formed, in particular integrally formed, on the valve housing 3a prior to welding to the inner container 4. The welding bead 10 is covered during welding by the inner container 4. The weld bead 10 is designed in particular web-like or rib-like and / or continuous or continuous. The weld bead 10 is formed in cross section, for example, substantially triangular, square, rectangular, trapezoidal or convex or curved.
Besonders bevorzugt erfolgt ein Verschweißen des Innenbehälters 4 mit dem Ventilgehäuse 3 a entlang des Schweißwulstes 10, so daß eine definierte, insbesondere zumindest im wesentlichen linienförmige Verbindung zwischen dem Ventilgehäuse 3a einerseits und dem Innenbehälter 4 andererseits ermöglicht wird. So kann mit verhältnismäßig wenig Ultraschallenergie eine definierte und dichte Verbindung zwischen dem Ventilgehäuse 3 a und dem Innenbehälter 4 erreicht werden. Der Schweißwulst 10 kann jedoch nicht nur beim Ultraschallschweißen, sondern auch beim sonstigen Schweißen eingesetzt werden. Der Schweißwulst 10 weist vorzugsweise eine Höhe und/oder Breite von mindestens 0,2 mm und/oder von höchstens 0,8 mm, besonders bevorzugt von weniger als 0,5 mm, auf. Ganz besonders bevorzugt beträgt die Höhe und/oder Breite im wesentlichen 0,3 mm.Particularly preferably, a welding of the inner container 4 with the valve housing 3 a along the Schweißwulstes 10 so that a defined, in particular at least substantially linear connection between the valve housing 3a on the one hand and the inner container 4 on the other hand is possible. Thus, a defined and sealed connection between the valve housing 3 a and the inner container 4 can be achieved with relatively little ultrasound energy. However, the weld bead 10 can be used not only in ultrasonic welding but also in other welding. The welding bead 10 preferably has a height and / or width of at least 0.2 mm and / or of at most 0.8 mm, particularly preferably less than 0.5 mm. Most preferably, the height and / or width is substantially 0.3 mm.
Besonders bevorzugt endet der Schweißwulst 10 in einer im Querschnitt zumindest im wesentlichen rechteckigen Kante oder Spitze. Der Schweißwulst 10 ist im Querschnitt insbesondere im wesentlichen dreieckförmig oder trapezförmig ausgebildet oder mit einer zumindest im wesentlichen dreieckförmigen oder tra- pezförmigen Spitze zum freien Ende hin verschen.Particularly preferably, the weld bead 10 ends in an edge or tip which is at least substantially rectangular in cross-section. The weld bead 10 is formed in cross-section in particular substantially triangular or trapezoidal shape or verschen with an at least substantially triangular or trapezoidal tip towards the free end.
Besonders bevorzugt erstreckt sich der Schweißwulst 10 zumindest im wesentlichen um einen Umfang des Ventilgehäuses 3a bzw. einer mit dem Innenbehälter 4 zu verbindenden Oberfläche des Ventilgehäuses 3 a.Particularly preferably, the welding bead 10 extends at least substantially around a circumference of the valve housing 3 a or a surface of the valve housing 3 a to be connected to the inner container 4.
Besonders bevorzugt erstrecken sich die Schweißwülste 10 bis zu den freien Längskanten der Seitenflügel 3c, gegebenenfalls sogar etwas seitlich über diese hinaus, um auch im Bereich dieser Kanten eine gute Abdichtung und Verbindung mit dem Innenbehälter 4 nach dem Verschweißen sicherzustellen.Particularly preferably, the welding beads 10 extend to the free longitudinal edges of the side wings 3c, possibly even slightly laterally beyond them, to ensure a good seal and connection with the inner container 4 after welding in the region of these edges.
Besonders bevorzugt bildet der Schweißwulst 10 eine geschlossene Schleife. Jedoch kann es sich auch um einen nur endlichen, also keine geschlossene Schleife bildenden Steg, Rippe o. dgl. handeln.Particularly preferably, the welding bead 10 forms a closed loop. However, it can also be a fin, ie no closed loop forming web, rib o. The like. Act.
Anstelle eines durchgehenden Schweiß wulstes 10 können auch mehrere Abschnitte, die beispielsweise einander überlappen und/oder nur sehr geringe Abstände aufweisen, vorgesehen sein.Instead of a continuous welding bead 10 can also be several sections, for example, overlap each other and / or have only very small distances may be provided.
Besonders bevorzugt sind mindestens zwei Schweißwülste 10 vorgesehen, die beabstandet bzw. parallel zueinander verlaufen. So kann eine Art "Doppeldichtung" bzw. zweifache linienmäßige Verbindung zwischen dem Ventilgehäuse 3a einerseits und dem Innenbehälter 4 andererseits erreicht werden. Beim Verschweißen des Innenbehälters 4 mit dem Ventilgehäuse 3a erfolgt ein Aufschmelzen des Schweißwulstes 10 bzw. der Schweißwülste 10 und dementsprechend ein Abflachen und Verbinden mit dem Innenbehälter 4.Particularly preferably, at least two welding beads 10 are provided which are spaced or parallel to each other. Thus, a kind of "double seal" or double line connection between the valve housing 3a on the one hand and the inner container 4 on the other hand can be achieved. When the inner container 4 is welded to the valve housing 3a, the welding bead 10 or the welding beads 10 are melted and, accordingly, a flattening and bonding to the inner container 4 takes place.
In Fig. 1 sind nur aus Veranschaulichungsgründen die Schweißwülste 10 dargestellt. Tatsächlich sind die Schweißwülste 10 bei angeschweißtem Innenbehälter 4 zumindest im wesentlichen nicht mehr vorhanden bzw. sichtbar.In Fig. 1, the Schweißwülste 10 are shown only for illustrative reasons. In fact, the welding beads 10 are at least substantially no longer present or visible when the inner container 4 is welded.
Besonders bevorzugt sind das Ventilgehäuse 3a und zumindest die innere Schicht des Innenbehäiters 4 aus dem gleichen Material hergestellt. Dies erleichtert das Verbinden, insbesondere Verschweißen. Dies ist jedoch nicht unbedingt erforderlich. Es ist auch möglich, daß unterschiedliche Materialien eingesetzt werden, die miteinander verbindbar sind, insbesondere durch Verschweißen oder auf sonstige geeignete Art und Weise, wie bereits beschrieben.Particularly preferably, the valve housing 3a and at least the inner layer of the Innenbehäiters 4 are made of the same material. This facilitates the joining, in particular welding. However, this is not essential. It is also possible that different materials are used, which are connectable to each other, in particular by welding or other suitable manner, as already described.
Wenn der Innenbehälter 4 aus einem einschichtigen Material hergestellt ist, bildet dieses Material auch die innere Schicht. Der Begriff "innere Schicht" ist also auch so verstehen, daß er eine einschichtige Ausbildung umfaßt.When the inner container 4 is made of a single-layer material, this material also forms the inner layer. The term "inner layer" is thus also understood to include a single-layered training.
Beim Darstellungsbeispiel besteht das Ventilgehäuse 3a und/oder die innere Schicht des Innenbehälters 4 vorzugsweise aus Polyethylen. Dieses Material weist gegenüber dem im Stand der Technik verwendeten Polypropylen eine wesentlich höhere Diffusionsdichtigkeit auf. Des weiteren läßt sich dieses Material auch durch Ultraschall verschweißen.In the illustrated embodiment, the valve housing 3a and / or the inner layer of the inner container 4 is preferably made of polyethylene. This material has a much higher diffusion-tightness than the polypropylene used in the prior art. Furthermore, this material can also be welded by ultrasound.
Alternativ kann für das Ventilgehäuse 3a und/oder die innere Schicht des Innenbehälters 4 insbesondere auch Polyamid eingesetzt werden. Hier ergeben sich insbesondere entsprechende Vorteile wie bei der Verwendung von Polyethylen.Alternatively, polyamide can be used in particular for the valve housing 3a and / or the inner layer of the inner container 4. This results in particular corresponding advantages as in the use of polyethylene.
Es ist anzumerken, daß das Ventilgehäuse 3a nicht vollständig aus dem genannten Material bestehen muß. Vielmehr kann gemäß einer nicht dargestellten Ausführungsvariante das Ventilgehäuse 3 a auch bereichsweise aus einem anderen Material hergestellt sein. Beispielweise ist es gemäß einer nicht dargestellten Ausfuhrungsvariante möglich, das Ventilgehäuse 3 a in dem Bereich, in dem es nicht mit dem Innenbehälter 4 verbunden oder von diesem abgedeckt wird, aus einem anderen Material herzustellen und/oder mit einer einem anderen Material herzustellen und/oder mit einer Abdeckung aus einem anderen Material zu versehen, wobei das andere Material insbesondere eine höhere Diffusionsdichtigkeit oder sonstige vorteilhafte Eigenschaften aufweist. Beispielsweise ist es möglich, eine diffusionsdichte Abdeckung in diesen ande- ren Bereichen anzuspritzen, besonders bevorzugt durch sogenannte "Bi- Injektion", also Spritzen des anderen Materials in der gleichen Spritzform gegen ein erstes Material.It should be noted that the valve housing 3a does not have to be made entirely of said material. Rather, according to an embodiment variant, not shown, the valve housing 3 a may also be partially made of a different material. For example, it is possible according to an embodiment not shown, the valve housing 3 a in the area where it is not connected to the inner container 4 or covered by this, to produce from a different material and / or with a another material to produce and / or provided with a cover of a different material, wherein the other material in particular has a higher diffusion-tightness or other advantageous properties. For example, it is possible to inject a diffusion-proof covering in these other areas, particularly preferably by so-called "bi-injection", ie spraying of the other material in the same injection mold against a first material.
Einzelne Merkmale und konstruktive Lösungen der beschriebenen Ausftihrungs- Varianten können auch beliebig miteinander kombiniert und/Oder bei sonstigen Abgabevorrichtungen eingesetzt werden. Individual features and constructive solutions of Ausfüihrungs- variants described can also be arbitrarily combined with each other and / or used in other dispensing devices.
