Description

Die Erfindung betrifft eine Applikationsvorrichtung mit einem stift- oder tubenartigen Aufnahmekörper für ein flüssiges oder viskoses Applikationsmedium, nämlich lösungsmittelhaltige Lacke, wobei am Aufnahmekörper Mittel zum Befestigen einer Dosier- und Abgabeeinrichtung des Applikationsmediums sowie eine lösbare Abdeckkappe vorgesehen sind, sowie weiterhin mit einem trichterförmigen Mundstück, welches eine, auch austauschbare Applikationsspitze aufnimmt, gemäß Oberbegriff des Anspruchs 1.The invention relates to an application device with a pen-like or tube-like receptacle for a liquid or viscous application medium, namely solvent-based paints, with means for attaching a metering and dispensing device for the application medium and a detachable cover cap being provided on the receptacle, and also with a funnel-shaped mouthpiece, which accommodates an application tip, which can also be exchanged, according to the preamble of claim 1.

Aus der DE 10 2008 021 441 A1 ist ein Applikationsstift vorbekannt, welcher dem Applizieren eines flüssigen oder viskosen Applikationsmediums dient. Diesbezüglich ist ein Gehäuse mit einem Reservoir zur Aufnahme des Applikationsmediums vorgesehen. Der Applikationsstift umfasst weiterhin ein stiftförmiges Gehäuse mit einem Adapter, in welchem eine Applikatorspitze mit Applikatorelement vorgesehen ist. Das stab- oder stiftförmige Applikatorelement besteht aus einem porösen Material, welches für ein kapillares Durchströmen des Applikationsmediums geeignet ist und eine ausreichende Festigkeit besitzt. Der Applikationsstift verfügt über eine Verschlusskappe, die auf das Gehäuse bzw. auf den Adapter mit Applikatorelement aufsetzbar ist, um die Applikatorspitze zu schützen. Ein Patronenkörper ist mit einer membranartigen Wandung verschlossen, die aus einem gummielastischen Material besteht. Dieser Wandabschnitt wird durch eine Kanüle im Bedarfsfall durchstoßen, so dass eine Benutzung des Patronenkörpers möglich ist und ein Fluss des Applikationsmediums erreicht werden kann. Beim Durchstoßen sollen sich im Bereich der Membran Lappen ausbilden, die nach dem Zurückbewegen der Kanüle die Patrone wieder möglichst dicht verschließen. Ob und inwieweit ein solcher Verschluss sich nach Zurückziehen der Kanüle wieder einstellt, bleibt mehr oder weniger dem Zufall überlassen, so dass keine reproduzierbaren Verhältnisse beim Einsatz eines derartigen Applikators gegeben sind. Die DE 10 2008 021 441 A1 offenbart den Oberbegriff des Anspruchs 1.From the DE 10 2008 021 441 A1 an application pen is already known which is used to apply a liquid or viscous application medium. In this regard, a housing with a reservoir for receiving the application medium is provided. The application pen furthermore comprises a pen-shaped housing with an adapter in which an applicator tip with an applicator element is provided. The rod-shaped or pen-shaped applicator element consists of a porous material which is suitable for a capillary flow through the application medium and which has sufficient strength. The application pen has a closure cap that can be placed on the housing or on the adapter with the applicator element in order to protect the applicator tip. A cartridge body is closed with a membrane-like wall made of a rubber-elastic material. If necessary, this wall section is pierced by a cannula, so that the cartridge body can be used and the application medium can flow. When it is pierced, lobes should form in the area of the membrane which, after the cannula has been moved back, close the cartridge as tightly as possible. Whether and to what extent such a closure is established again after the cannula has been withdrawn is more or less left to chance, so that no reproducible conditions exist when using such an applicator. The DE 10 2008 021 441 A1 discloses the preamble of claim 1.

Bei dem Applikationsstift nach DE 20 2007 010 286 U1 wird eine Flüssigkeit zu Mal- oder Zeichenzwecken im hülsenartigen Schaft aufgenommen. Am dortigen Mundstück sowie an der vorhandenen Steckkappe sind Verriegelungsmittel vorgesehen, um die auf das Mundstück aufgesetzte Steckkappe gegen ein Abnehmen zu verriegeln. Die Führung des Applikationsmediums vom hülsenartigen Schaft hin zur Schreibspitze erfolgt allein durch die Eigenschaften des Applikatorelements, und zwar mehr oder weniger ungesteuert. Kommt es bei Gebrauchsunterbrechungen zu einer Beeinträchtigung der Kapillarfunktion der Applikatorspitze, ist bei einem Wiederingebrauchnehmen von schlechteren Produkteigenschaften auszugehen.At the application pen DE 20 2007 010 286 U1 a liquid is absorbed in the sleeve-like shaft for painting or drawing purposes. Locking means are provided on the mouthpiece there and on the existing plug-in cap in order to prevent the plug-in cap placed on the mouthpiece from being removed. The application medium is guided from the sleeve-like shaft to the writing tip solely through the properties of the applicator element, more or less in an uncontrolled manner. If the capillary function of the applicator tip is impaired in the event of interruption of use, poorer product properties can be assumed when it is used again.

Bei der Vorrichtung zum Applizieren eines flüssigen, medizinischen Behandlungsmediums nach DE 10 2007 046 600 A1 wird von der Grundkonstruktion eines sogenannten Markers ausgegangen, und zwar auf der Basis eines röhrchenartigen Körpers, der ein Behandlungsmedium aufnimmt. Weiterhin ist eine Ventil- oder Dosierpumpe in einem Einsatz eines hülsenartigen Mundstücks ausgebildet und es ist eine Applikationsspitze nebst Verschlusskappe vorhanden. Durch axiales Verschieben der Applikationsspitze gegen die Wirkung einer in der Dosierpumpe vorgesehenen Rückstellfeder ist ein Betätigen der Dosierpumpe möglich, und zwar zur Entnahme einer dosierten Menge des Behandlungsmediums aus den Behältern und zur Abgabe dieser Menge an die Applikationsspitze. Wenn die von der Dosierpumpe bereitgestellte Menge des Mediums verbraucht ist, muss der entsprechende Stift abgesetzt und ein erneutes Pumpen vorgenommen werden.In the device for applying a liquid medical treatment medium according to DE 10 2007 046 600 A1 is based on the basic construction of a so-called marker, on the basis of a tube-like body that receives a treatment medium. Furthermore, a valve or metering pump is designed in an insert of a sleeve-like mouthpiece and an application tip and a closure cap are provided. By axially displacing the application tip against the action of a return spring provided in the metering pump, it is possible to actuate the metering pump to remove a metered amount of the treatment medium from the containers and to deliver this amount to the application tip. When the amount of medium provided by the dosing pump has been used up, the corresponding pin must be removed and the pump must be pumped again.

Die Verwendung einer derartigen Dosierpumpe schränkt also den Einsatz eines Applikationsstifts dann ein, wenn z.B. zum Zweck der Versiegelung von Möbelkanten oder Reparaturen an Möbelstücken möglichst Linien gleicher Strichstärke bei großer Länge zu ziehen sind. Jede Unterbrechung des Auftragsvorgangs führt zu einer sichtbaren Veränderung der Strichstärke bzw. der Menge des aufgebrachten Materials.The use of such a metering pump restricts the use of an application pen when e.g. For the purpose of sealing the edges of furniture or repairs to pieces of furniture, lines of the same line width should be drawn over long distances. Every interruption of the application process leads to a visible change in the line thickness or the amount of material applied.

Die FR 2919585 A1 offenbart eine Vorrichtung Aufbewahren und Auftragen eines kosmetischen Produktes, beispielsweise ein Produkt zum Auftragen auf den Körper oder das Gesicht. Ein dortiges Ventil sorgt dafür, dass einerseits ein unerwünschtes Austreten des Produktes, zum Beispiel bei Druckveränderungen im Rahmen eines Flugzeugtransportes ausgeschlossen ist, jedoch beim Ausüben eines manuellen Druckes auf den Vorratsraum über eine Ventilöffnung das Produkt zum Auftragselement, zum Beispiel einem Schaumstoffkörper gelangt. Bei einer weiteren Ausgestaltung ist das Ventil als Rückschlagventil ausgeführt, wobei es darum geht, den Eintritt von Verschmutzungen aus der Umgebung in den Vorratsraum zu verhindern.The FR 2919585 A1 discloses a device for storing and applying a cosmetic product, for example a product for application to the body or face. A valve there ensures that, on the one hand, an undesired escape of the product, for example in the event of pressure changes within the framework of a Transport by air is excluded, but when manual pressure is exerted on the storage space, the product reaches the application element, for example a foam body, via a valve opening. In a further embodiment, the valve is designed as a check valve, the aim being to prevent contamination from the environment from entering the storage space.

Aus dem Vorgenannten ist es daher Aufgabe der Erfindung, eine weiterentwickelte Applikationsvorrichtung mit einem stift- oder tubenartigen Aufnahmekörper für ein flüssiges oder viskoses Applikationsmedium, insbesondere lösungsmittelhaltige Lacke anzugeben, welche eine sichere und einfache Handhabung ermöglicht und mit deren Hilfe ein möglichst vollständiges Ausnutzen des vorhandenen Applikationsmediums erfolgen kann. Dabei sollen auch notwendige Arbeitsunterbrechungen möglich sein, ohne dass es bei erneuter Inbetriebnahme der Vorrichtung zu Problemen bei deren Handhabung kommt.From the above, it is therefore the object of the invention to provide a further developed application device with a pen or tube-like receptacle for a liquid or viscous application medium, in particular solvent-based paints, which enables safe and simple handling and with the help of which the most complete possible use of the existing application medium can be done. Necessary work interruptions should also be possible, without problems in handling the device when it is started up again.

Es wird demnach von einer Applikationsvorrichtung mit einem stift- oder tubenartigen Aufnahmekörper für ein flüssiges oder viskoses Applikationsmedium, nämlich für lösungsmittelhaltige Lacke, z. B. zum Zweck der Reparatur von Möbelstücken, ausgegangen. Der Aufnahmekörper kann bei einer bevorzugten Ausführungsform eine an sich bekannte Tube aus metallischem Material mit entsprechender Tubenöffnung sein.It is therefore of an application device with a pen or tube-like receiving body for a liquid or viscous application medium, namely for solvent-based paints, eg. B. for the purpose of repairing furniture, assumed. In a preferred embodiment, the receiving body can be a known tube made of metallic material with a corresponding tube opening.

Am Aufnahmekörper sind Mittel zum Befestigen einer Dosier- und Abgabeeinrichtung für das Applikationsmedium vorhanden. Weiterhin ist eine lösbare Abdeckkappe vorgesehen. Ebenso ist ein trichterförmiges Mundstück vorhanden, welches eine, auch austauschbare, Applikationsspitze aufnimmt. Die Applikationsspitze kann z.B. aus einem filzartigen Material bestehen und eine Spitze mit unterschiedlicher Spitzenform oder aber auch eine angeschrägte Spitzenfläche besitzen.Means for attaching a metering and dispensing device for the application medium are provided on the receiving body. A detachable cover cap is also provided. There is also a funnel-shaped mouthpiece which accommodates an application tip, which can also be exchanged. The application tip can e.g. consist of a felt-like material and have a tip with a different tip shape or a beveled tip surface.

Erfindungsgemäß ist im Mundstück ein zum Aufnahmekörper offener Hohlraum ausgebildet. Dieser offene Hohlraum nimmt einen Ventilträgerkörper rastend fixierbar auf.According to the invention, a cavity open to the receiving body is formed in the mouthpiece. This open cavity accommodates a valve carrier body in a latching manner.

Der Ventilträgerkörper ist seinerseits form- und/oder kraftschlüssig mit dem Aufnahmekörper und einer dort vorhandenen Austrittsöffnung, insbesondere einer Tubenöffnung, für das Applikationsmedium verbindbar.For its part, the valve support body can be connected in a form-fitting and / or force-fitting manner to the receiving body and to an outlet opening there, in particular a tube opening, for the application medium.

Der Ventilträgerkörper weist eine erste Ringnut auf, in welche ein Membranventilplättchen einsetzbar ist, welches mit einer Durchgangsöffnung des Ventilträgerkörpers in Verbindung steht, so dass die Austrittsmenge des Applikationsmediums steuerbar ist. Weiterhin dichtet das Membranventilplättchen gleichzeitig den Ventilträgerkörper zum Mundstückinneren ab. Es kommt also demnach dem Membranventilplättchen eine doppelte Funktion zu, nämlich einerseits die erforderliche Abdichtung zwischen den vorerwähnten Komponenten sowie andererseits der gesteuerten Produktabgabe.The valve carrier body has a first annular groove into which a membrane valve plate can be inserted, which is connected to a through opening of the valve carrier body, so that the discharge amount of the application medium can be controlled. Furthermore, the diaphragm valve plate simultaneously seals the valve carrier body from the inside of the mouthpiece. The membrane valve plate therefore has a double function, namely, on the one hand, the necessary sealing between the aforementioned components and, on the other hand, the controlled product release.

Fertigungstechnisch wird die Membran des Membranventilplättchens mit ein oder mehreren Durchstoßungen versehen, die eine gezielte Produktdurchtrittsmenge gestatten, wenn ein entsprechender Druck aufgebaut ist. Bei Nichtgebrauch bzw. Druckabfall schließen sich diese Durchstoßungen und es wird ein Austrocknen des Applikationsmediums bzw. ein Härtevorgang ausgeschlossen. Da die Durchstoßungen werkseitig ausgeführt werden, sind reproduzierbare Verhältnisse ja nach eingesetztem Applikationsmedium erreichbar.In terms of manufacturing technology, the membrane of the membrane valve plate is provided with one or more perforations, which allow a targeted amount of product to pass through when a corresponding pressure is built up. When not in use or when there is a drop in pressure, these perforations close and the application medium does not dry out or a hardening process occurs. Since the penetrations are carried out at the factory, reproducible conditions can be achieved depending on the application medium used.

Bei einer bevorzugten Ausgestaltung weist der Ventilträgerkörper eine zweite, zum Aufnahmekörper weisende Ringnut auf, wobei die Austrittsöffnung des Aufnahmekörpers, z.B. die Tubenöffnung, in diese zweite Ringnut eintaucht. Hierdurch ist gewährleistet, dass das Applikationsmedium verlustfrei in Richtung Ventilträgerkörper, dort aufgenommener Membran hin zum Applikationsstift im Mundstück fließen kann.In a preferred embodiment, the valve support body has a second annular groove facing the receiving body, the outlet opening of the receiving body, e.g. the tube opening, dips into this second annular groove. This ensures that the application medium can flow without loss in the direction of the valve carrier body, the membrane accommodated there, and the application pin in the mouthpiece.

Bei einer wiederum bevorzugten Ausführungsform besitzt der Ventilträgerkörper zum Aufnahmekörper hin gerichtete Rastmittel, wobei eine umlaufende Kragung im Bereich der Austrittsöffnung von diesen Rastmitteln hintergriffen wird, so dass der Ventilträgerkörper entsprechend fixierbar ist. Durch die bevorzugt vorgeschlagene Rastbefestigung wird ein Abdrehen bzw. Abschrauben des kompletten Mundstücks vom Aufnahmekörper, versehentlich oder absichtlich, verhindert.In another preferred embodiment, the valve carrier body has latching means directed towards the receiving body, a circumferential collar in the area of the outlet opening being engaged from behind by these latching means so that the valve carrier body can be fixed accordingly. The preferably proposed latching attachment prevents the complete mouthpiece from being twisted or unscrewed from the receiving body, accidentally or intentionally.

Das Membranventilplättchen besitzt einen verstärkten, umlaufenden, beidseitig hervorstehenden Rand bzw. eine entsprechend ausgebildete Kragung, wobei der Rand einerseits in die erste Ringnut eingreift und andererseits die Abdichtung zum Mundstückinneren bewirkt.The diaphragm valve plate has a reinforced, circumferential edge protruding on both sides or a correspondingly formed collar, the edge engaging in the first annular groove on the one hand and sealing the mouthpiece inside on the other.

Innerhalb des vom Rand umschlossenen Raums ist die eigentliche Durchtrittsmembran bezüglich des Applikationsmediums ausgebildet, welche bevorzugt aus einem thermoplastischen Polymerkunststoff besteht.Within the space enclosed by the edge, the actual passage membrane with respect to the application medium is formed, which preferably consists of a thermoplastic polymer.

Das die Abdeckkappe aufnehmende Ende des Mundstücks weist erfindungsgemäß eine mehrfach konisch ausgeführte bzw. konisch abgestufte Gestalt mit Hohlraum zur Aufnahme der Applikationsspitze auf, wobei die Innenkontur der Abdeckkappe mindestens teilweise der konischen Gestalt komplementär ausgebildet ist.According to the invention, the end of the mouthpiece receiving the cap has a multiple conical or conically stepped shape with a cavity for receiving the application tip, the inner contour of the cap being at least partially complementary to the conical shape.

Am geschlossenen Ende der Abdeckkappe ist in deren Innenraum ein Dichteinsatz angeordnet, wobei bei aufgesetzter Kappe das freie Ende der Applikationsspitze vom Dichteinsatz verschlossen wird. Der Dichteinsatz kann diesbezüglich aus einem zum Zweck der Dichtung optimierten Material, z.B. einem Polymer geringer Dichte hergestellt werden, wobei hingegen die eigentliche Abdeckkappe aus einem kostengünstigeren, härteren Kunststoffmaterial bestehen kann.At the closed end of the cover cap, a sealing insert is arranged in its interior, with the free end of the application tip being closed by the sealing insert when the cap is in place. In this regard, the sealing insert can be made of a material optimized for sealing purposes, e.g. a polymer of low density, whereas the actual cover cap can consist of a cheaper, harder plastic material.

Insofern kann die Abdeckkappe aus Polypropylen gefertigt werden.In this respect, the cover cap can be made from polypropylene.

Das Mundstück und der Ventilträgerkörper bestehen bevorzugt aus einem glasfaserverstärkten Kunststoff, insbesondere einem glasfaserverstärkten Polyamid.The mouthpiece and the valve support body preferably consist of a glass fiber reinforced plastic, in particular a glass fiber reinforced polyamide.

Der Aufnahmekörper ist bei einer bevorzugten Ausführungsform als Tube ausgebildet, welche in ihrem Inneren Schüttelkörper zur Mischung des Applikationsmediums aufnimmt.In a preferred embodiment, the receiving body is designed as a tube which in its interior receives shaking bodies for mixing the application medium.

Erfindungsgemäß sind die Schüttelkörper nicht kugelförmig, sondern mit einer vom Kreisrunden oder Kugelförmigen abweichenden, vieleckigen Form ausgebildet. Ein Festklemmen der Schüttelkörper in Ecken des tubenförmigen Aufnahmekörpers wird hierdurch verhindert.According to the invention, the shaking bodies are not spherical, but rather have a polygonal shape that deviates from the circular or spherical shape educated. This prevents the shaking bodies from jamming in corners of the tubular receiving body.

Die bevorzugt eingesetzte Tube ist vom Tubenende bzw. Tubenboden her aufrollbar. Diesbezüglich kann ein sogenannter Tubenschlüssel Verwendung finden. Die für den Austritt des Mediums erforderlichen Druckverhältnisse werden also durch Druck auf die Tube bzw. durch den Aufrollvorgang zur Verfügung gestellt.The tube that is preferably used can be rolled up from the end of the tube or the bottom of the tube. A so-called tube key can be used in this regard. The pressure conditions required for the medium to exit are therefore made available by pressure on the tube or by the rolling process.

Die Erfindung soll nachstehend anhand eines Ausführungsbeispiels sowie unter Zuhilfenahme einer Figur näher erläutert werden.The invention will be explained in more detail below using an exemplary embodiment and with the aid of a figure.

Die Figur zeigt hierbei eine Längsschnittdarstellung einer Applikationsvorrichtung mit tubenförmigem Aufnahmekörper sowie Mundstück, Verschlusskappe und der Dosier- und Abgabeeinrichtung.The figure shows a longitudinal sectional view of an application device with a tube-shaped receiving body as well as a mouthpiece, closure cap and the dosing and dispensing device.

Bei der Applikationsvorrichtung gemäß Ausführungsbeispiel wird also von einem Aufnahmekörper 1 in Tubenform ausgegangen. Dieser Aufnahmekörper 1 besitzt ein oberes Tubenende 2 mit einer umlaufenden Kragung 3.In the application device according to the exemplary embodiment, a receiving body 1 in the form of a tube is assumed. This receiving body 1 has an upper tube end 2 with a circumferential collar 3.

Weiterhin ist ein Mundstück 4 vorhanden, welches einen zum Aufnahmekörper 1 hin offenen Hohlraum aufweist. Innerhalb des Mundstücks 4 ist ein Ventilträgerkörper 5 eingesetzt bzw. dort rastend fixierbar aufgenommen.Furthermore, there is a mouthpiece 4 which has a cavity that is open towards the receiving body 1. Inside the mouthpiece 4, a valve support body 5 is inserted or received there in a latching manner.

Der Ventilträgerkörper 5 steht seinerseits form- und kraftschlüssig mit dem Aufnahmekörper 1 und der dort vorhandenen umlaufenden Kragung in Verbindung.The valve carrier body 5 for its part is positively and non-positively connected to the receiving body 1 and the circumferential collar present there.

Eine erste, obere Ringnut 51 des Ventilträgerkörpers 5 nimmt einen unteren umlaufenden Rand 61 eines Membranventilplättchens 6 auf.A first, upper annular groove 51 of the valve support body 5 receives a lower circumferential edge 61 of a membrane valve plate 6.

Gleichzeitig dichtet ein oberer Rand 62 des Membranventilplättchens 6 den Ventilträgerkörper 5 zum Mundstückinneren ab.At the same time, an upper edge 62 of the membrane valve plate 6 seals the valve support body 5 from the inside of the mouthpiece.

Weiterhin nimmt das Mundstück 4 in einem inneren Durchgangshohlraum die eigentliche Applikationsspitze 7 auf, welche im Gebrauchsfall, d.h. bei abgenommener Abdeckkappe 8 mit dem vorderen Ende frei liegt.Furthermore, the mouthpiece 4 accommodates the actual application tip 7 in an inner passage cavity, which in use, i.e. when the cap 8 is removed, the front end is exposed.

Erkennbar ist aus der figürlichen Darstellung darüber hinaus, dass der Ventilträgerkörper 5 eine zweite Ringnut 52 aufweist, wobei die Austrittsöffnung des Aufnahmekörpers 1 bzw. der Tube in diese zweite Ringnut eintaucht.It can also be seen from the figurative representation that the valve support body 5 has a second annular groove 52, the outlet opening of the receiving body 1 or the tube dipping into this second annular groove.

Wie ebenfalls aus der Figur ersichtlich, weist das Membranventilplättchen 6 einen verstärkten, umlaufenden, beidseitig hervorstehenden Rand auf, wobei der Rand einerseits in die erste Ringnut eingreift als auch andererseits die Abdichtung zum Mundstückinneren bewirkt.As can also be seen from the figure, the diaphragm valve plate 6 has a reinforced, circumferential, edge protruding on both sides, the edge engaging in the first annular groove on the one hand and sealing the inside of the mouthpiece on the other.

Unterhalb des vom Rand umschlossenen Raums ist die eigentliche Membran 63 ausgebildet, welche aus einem thermoplastischen Polymerkunststoff besteht und die herstellungsseitig eine definierte Zahl von Durchstoßungen besitzt.Underneath the space enclosed by the edge, the actual membrane 63 is formed, which consists of a thermoplastic polymer and which has a defined number of perforations on the manufacturing side.

Wie weiterhin ersichtlich, ist das die Abdeckkappe 8 aufnehmende Ende des Mundstücks 4 mehrfach konisch 41; 42 ausgebildet, wobei die Innenkontur der Abdeckkappe 8 mindestens teilweise der konischen Gestalt komplementär ausgeführt wird, um einen dichten, festen Sitz der Kappe am Mundstückaußenumfang in dessen vorderen Bereich zu gewährleisten.As can also be seen, the end of the mouthpiece 4 receiving the cover cap 8 is conical several times 41; 42, the inner contour of the cover cap 8 being designed to be at least partially complementary to the conical shape in order to ensure a tight, firm fit of the cap on the outer circumference of the mouthpiece in its front area.

Am geschlossenen Ende besitzt die Abdeckkappe 8 in deren Innenraum befindlich einen Dichteinsatz 9, welcher bei aufgesetzter Kappe 8 das freie Ende der Applikationsspitze 7 verschließt und die Abdichtung verbessert.At the closed end, the cover cap 8 has a sealing insert 9 located in its interior, which when the cap 8 is in place closes the free end of the application tip 7 and improves the seal.

Der Dichteinsatz kann hier aus einem Polymer geringer Dichte, z.B. LDPE bestehen. Die Abdeckkappe selbst kann aus Polypropylen gefertigt werden.The sealing insert can be made of a low density polymer, e.g. LDPE exist. The cover cap itself can be made of polypropylene.

Gemäß einer bevorzugten Ausführungsform werden das Mundstück und der Ventilträgerkörper aus einem glasfaserverstärkten Kunststoff, insbesondere glasfaserverstärktem Polyamid gefertigt.According to a preferred embodiment, the mouthpiece and the valve support body are made from a glass fiber reinforced plastic, in particular glass fiber reinforced polyamide.

Im Inneren des Aufnahmekörpers 1 werden (in der Figur nicht gezeigte) Schüttelkörper eingebracht, wobei diese Schüttelkörper bevorzugt vom Kugelförmigen oder Kreisrunden abweichend eine vieleckige Gestalt besitzen.Shaking bodies (not shown in the figure) are introduced into the interior of the receiving body 1, these shaking bodies preferably having a polygonal shape deviating from spherical or circular shapes.

Im Gebrauchsfall dringt das Applikationsmedium vom Inneren des Aufnahmekörpers 1 in den Durchgangshohlraum des Ventilträgerkörpers 5 ein. Bei steigendem Druck werden die Nadelstärke aufweisenden, sich wiederum selbst verschließenden Löcher der Membran 63 durchdrungen und es gelangt das Applikationsmedium in den folgenden Zwischenhohlraum sowie über den Verbindungskanal 43 zur Applikationsspitze 7.When in use, the application medium penetrates from the interior of the receiving body 1 into the passage cavity of the valve carrier body 5. When the pressure rises, the self-closing holes of the membrane 63, which have the needle thickness, are penetrated and the application medium reaches the following intermediate cavity and via the connecting channel 43 to the application tip 7.

Die Menge des Applikationsmediums ist über die Druckverhältnisse im Aufnahmekörper, d.h. der Tube 1 gesteuert ausbringbar.The amount of application medium is determined by the pressure conditions in the receiving body, i.e. the tube 1 can be dispensed in a controlled manner.

Bei Nichtgebrauch verschließen sich die Durchstoßungen in der lösungsmittelresistenten Membran 63 und es wird das Innere des Aufnahmekörpers 1 abgedichtet. Mit Aufstecken der Abdeckkappe 8 auf das Mundstück 4 erfolgt auch diesbezüglich ein dichter Verschluss, wobei insbesondere der Einsatz 9 das offene Ende der Applikationsspitze gegen Austrocknen sichert.When not in use, the penetrations in the solvent-resistant membrane 63 close and the interior of the receiving body 1 is sealed. When the covering cap 8 is slipped onto the mouthpiece 4, a tight seal also takes place in this regard, with the insert 9 in particular securing the open end of the application tip against drying out.

Die eigentliche funktionsrelevante Dosier- und Abgabeeinrichtung besteht nur aus drei Teilen, nämlich Mundstück, Ventilträgerkörper und Membranventil. Die vorgenannten Teile sind durch Steck- und Rastverbindungen produktionstechnisch leicht verbindbar und im Gebrauchsfall gegen unbefugtes Öffnen gesichert.The actual function-relevant metering and dispensing device consists of only three parts, namely the mouthpiece, valve support body and diaphragm valve. The aforementioned parts can be easily connected in terms of production technology by means of plug and locking connections and are secured against unauthorized opening when in use.

Die Applikationsvorrichtung kann insbesondere als sogenannter Kanten-Lackstift zum deckenden Einfärben von Möbelstücken oder dergleichen Anwendung finden, ohne jedoch auf eine solche Anwendung beschränkt zu sein.The application device can be used in particular as a so-called edge touch-up stick for the opaque coloring of pieces of furniture or the like, but without being restricted to such an application.
