Definitions
- the invention relates to a metering device with a pumping device and an actuating handle associated with the pumping device, wherein the actuating handle is manufactured as a separate component and attached to the pumping device and wherein on a component of the pumping device, a protective cap enclosing at least one discharge opening is releasably securable.
- actuating handles are integrally formed on a corresponding housing part of the pumping device. This is in particular on the DE 33 15 334 A1 referenced, from which the one-piece molding of an actuating handle on a housing body designed as a nose olive is known.
- a discharge device in which a handle is designed as a separate component. This handle and a cap of the discharge are dimensioned so that the handle must be firmly connected before fitting the cap with the discharge.
- the object of the invention is to provide a metering device of the type mentioned, which has a reduced production cost.
- the protective cap is adapted to the shape of the actuating handle so that the handle can be attached to the pumping device even when the protective cap is fastened. This makes it possible to mount the actuating handle as the last component on the pumping device. It is not necessary to remove the protective cap from the pumping device before mounting the actuating handle.
- the final assembly can in particular also be carried out by the user, so that it is possible to pack the actuating handle in the unassembled state of the metering device, so that a smaller packing volume can be achieved as a result.
- the manufacturer of the metering device does not have to do the assembly himself.
- the actuating handle is attached by means of a latching connection to the pump device.
- the locking connection is designed as a permanent connection.
- This type of connection between actuating handle and pumping device allows a simple, especially tool-free installation, for example by the user. At the same time, however, it is suitable to transmit sufficient forces of the actuating handle on the pumping device. Due to the non-releasability of the connection between the actuating handle and the pumping device, it is possible to have both an actuating force in the sense of effecting a discharge stroke and a force acting in the opposite direction of force Force to initiate. So it's not just a discharge stroke manually generated, but also a return stroke. At the same time, the production of the non-detachable connection also provides protection against subsequent manipulation.
- the shaped body in which the actuating handle is formed as the media storage at least partially surrounding moldings.
- the shaped body has a substantially cylindrical basic shape.
- the shaped body deviates from the basic cylindrical shape, for. B. a relief structure or instead of the purely cylindrical basic shape in cross-section oval or elliptical basic shape.
- one of the end faces of the cylindrical basic shape may be open.
- the one end face opposite the other end face may be formed at least substantially closed and have an opening for placement on the pumping device.
- the outer shape of a metering device can be determined at least partially by the actuating handle. It is thereby changed in a simple manner, without having to change anything in the construction of the metering device, the pumping device or their shape.
- the separation of functional components and the actuation handle that is decisive for the design is advantageous, so that different actuation handles for the same functional device can optionally be used.
- Only the already separately mountable actuating handle is designed in different ways. The changes in the design can affect both the color and the shape. Thus, different colorations are possible, whereby metering devices for different people or with different content are distinguishable from each other. Multi-component injection molded parts with different haptic designs can be used particularly advantageously.

It is not necessary to remove the protective cap from the pumping device before mounting the actuating handle.
Die Endmontage kann insbesondere auch durch den Benutzer erfolgen, so dass es möglich ist, die Betätigungshandhabe im nicht montierten Zustand der Dosiervorrichtung beizupacken, so dass dadurch ein geringeres Packvolumen erzielbar ist. Der Hersteller der Dosiervorrichtung muss die Montage nicht selbst vornehmen.The final assembly can in particular also be carried out by the user, so that it is possible to pack the actuating handle in the unassembled state of the metering device, so that a smaller packing volume can be achieved as a result. The manufacturer of the metering device does not have to do the assembly himself.
In Ausgestaltung der Erfindung ist die Betätigungshandhabe mittels einer Rastverbindung an der Pumpvorrichtung befestigt. Vorzugsweise ist die Rastverbindung als unlösbare Verbindung gestaltet. Diese Art der Verbindung zwischen Betätigungshandhabe und Pumpvorrichtung erlaubt eine einfache, insbesondere auch werkzeuglose Montage, beispielsweise durch den Benutzer selbst. Gleichzeitig ist sie jedoch geeignet, ausreichende Kräfte der Betätigungshandhabe auf die Pumpvorrichtung zu übertragen. Durch die Nichtlösbarkeit der Verbindung zwischen der Betätigungshandhabe und der Pumpvorrichtung ist es möglich, sowohl eine Betätigungskraft im Sinne der Bewirkung eines Austraghubes als auch eine in entgegengesetzter Kraftrichtung wirkende Kraft einzuleiten. Es ist also nicht nur ein Austraghub manuell erzeugbar, sondern auch ein entsprechender Rückhub. Gleichzeitig bietet die Herstellung der nicht lösbaren Verbindung auch einen Schutz vor nachträglicher Manipulation.In an embodiment of the invention, the actuating handle is attached by means of a latching connection to the pump device. Preferably, the locking connection is designed as a permanent connection. This type of connection between actuating handle and pumping device allows a simple, especially tool-free installation, for example by the user. At the same time, however, it is suitable to transmit sufficient forces of the actuating handle on the pumping device. Due to the non-releasability of the connection between the actuating handle and the pumping device, it is possible to have both an actuating force in the sense of effecting a discharge stroke and a force acting in the opposite direction of force Force to initiate. So it's not just a discharge stroke manually generated, but also a return stroke. At the same time, the production of the non-detachable connection also provides protection against subsequent manipulation.
Vorteilhaft sind Ausgestaltungen der Erfindung, bei denen die Betätigungshandhabe als den Medienspeicher wenigstens bereichsweise umgebender Formkörper ausgebildet ist. Hierzu weist der Formkörper gemäß bevorzugter Ausgestaltung eine im wesentlichen zylindrische Grundform auf. Alternativ ist es möglich, dass der Formkörper Abweichungen von der zylindrischen Grundform aufweist, z. B. eine Relief struktur oder auch anstelle der rein zylindrischen Grundform eine im Querschnitt ovale oder elliptische Grundform. Dabei kann eine der Stirnflächen der zylindrischen Grundform offen ausgebildet sein. Die dieser einen Stirnfläche gegenüberliegende andere Stirnfläche kann zumindest weitgehend geschlossen ausgebildet sein und eine Öffnung zum Aufsetzen auf die Pumpvorrichtung aufweisen.Advantageous embodiments of the invention, in which the actuating handle is formed as the media storage at least partially surrounding moldings. For this purpose, the shaped body according to a preferred embodiment has a substantially cylindrical basic shape. Alternatively, it is possible that the shaped body deviates from the basic cylindrical shape, for. B. a relief structure or instead of the purely cylindrical basic shape in cross-section oval or elliptical basic shape. In this case, one of the end faces of the cylindrical basic shape may be open. The one end face opposite the other end face may be formed at least substantially closed and have an opening for placement on the pumping device.
Bei solchen Ausgestaltungen ist es vorteilhaft, wenn die äußere Gestalt einer Dosiervorrichtung wenigstens teilweise durch die Betätigungshandhabe bestimmbar ist. Sie wird dabei in einfacher Weise verändert, ohne dass am Aufbau der Dosiervorrichtung, der Pumpvorrichtung oder aber ihrer Gestalt etwas geändert werden muß. Vorteilhaft ist somit insbesondere die Trennung von Funktionsbauteilen und der für das Design maßgeblichen Betätigungshandhabe, so dass unterschiedliche Betätigungshandhaben für die gleiche Funktionsvorrichtung wahlweise eingesetzt werden können. Lediglich die ohnehin gesondert montierbare Betätigungshandhabe wird in jeweils anderer Weise gestaltet. Die Änderungen in der Gestaltung können dabei sowohl die Farb- als auch die Formgebung betreffen. So sind unterschiedliche Farbgebungen möglich, wodurch Dosiervorrichtungen für verschiedene Personen oder mit unterschiedlichem Inhalt voneinander unterscheidbar sind. Mehrkomponenten-Spritzgussteile mit unterschiedlichen haptischen Gestaltungen sind besonders vorteilhaft einsetzbar. Hier können insbesondere unterschiedliche Materialkomponenten wie PP oder TPE mittels unterschiedlicher Extruder einer entsprechend angepassten Spritzgussform zugeführt werden, so dass sich je nach Bedarf insbesondere glatte und samtartig griffige Bereiche bei der Betätigungshandhabe schaffen lassen. Ebenso ist es denkbar, beispielsweise für Kinder, dem Formkörper eine bunte und/oder figurenartige Gestalt zu geben. Derartige Gestaltungen sind für Kinder besonders ansprechend und daher eine gewisse ergänzende Motivation für die Benutzung der Dosiervorrichtung.In such embodiments, it is advantageous if the outer shape of a metering device can be determined at least partially by the actuating handle. It is thereby changed in a simple manner, without having to change anything in the construction of the metering device, the pumping device or their shape. Thus, in particular, the separation of functional components and the actuation handle that is decisive for the design is advantageous, so that different actuation handles for the same functional device can optionally be used. Only the already separately mountable actuating handle is designed in different ways. The changes in the design can affect both the color and the shape. Thus, different colorations are possible, whereby metering devices for different people or with different content are distinguishable from each other. Multi-component injection molded parts with different haptic designs can be used particularly advantageously. Here, in particular, different material components such as PP or TPE by means of different Extruder be fed to a suitably adapted injection mold, so that in particular can create smooth and velvety grip areas in the actuating handle as needed. Likewise, it is conceivable, for example, for children, to give the shaped body a colorful and / or figure-like shape. Such designs are particularly appealing to children and therefore provide some complementary motivation for using the dosing device.
Es kann von Vorteil sein, wenn beim Aufsetzen der Betätigungshandhabe bereits ein Austraghub durchgeführt wird. Soweit die Pumpvorrichtung zu Beginn ihres Einsatzes eines sogenannten Primings bedarf, bevor tatsächlich Medium ausgetragen wird, kann beim Aufsetzen der Handhabe unbewusst bereits ein Austraghub erzeugt werden, wodurch die Anzahl weiterer Hübe, die für das Priming erforderlich sind, verringert wird. Das Priming ist das Befüllen der Pumpkammer der Pumpvorichtung mit Medium aus dem Medienspeicher, um sicherzustellen, dass tatsächlich ein Medienaustrag in der gewünschten Dosierung durch die Austragöffnung erfolgt.It may be advantageous if a discharge stroke is already carried out when placing the actuating handle. As far as the pumping device at the beginning of their use requires a so-called priming before actually medium is discharged, a discharge stroke can unconsciously already be generated when placing the handle, whereby the number of further strokes that are required for priming is reduced. The priming is the filling of the pumping chamber of the pumping device with medium from the media reservoir, to ensure that actually takes place a Medienaustrag in the desired dosage through the discharge opening.

Eine Dosiervorrichtung nach
Radial in Abstand zu dem inneren Zylindermantel 4 bildet der innere Pumpgehäuseteil 3 einen äußeren Zylindermantel 5, der - wie auch der innere Zylindermantel 4 - einstückig an dem Verschlussdeckel 1 angeformt ist. Der äußere Zylindermantel 5 ist koaxial zu dem inneren Zylindermantel ausgerichtet. Zwischen dem inneren Zylindermantel 4 und dem äußeren Zylindermantel 5 verbleibt ein ringförmiger Verdrängerraum 14, auf den nachfolgend noch näher eingegangen wird und der zu einer Pumpkammer zählt.Radially in distance from the inner cylinder shell 4, the inner
Relativ zu dem lagefest am Medienspeicher befestigbaren Aufnahmeteil 2 einschließlich des inneren Pumpgehäuseteils 3 ist eine Pumpeinheit hubbeweglich gelagert. Die hubbewegliche Pumpeinheit weist einen äußeren Pumpgehäuseteil 8 auf, der mit einer inneren Pumpkolbeneinheit 9 bis 11 fest verbunden ist. Die Pumpkolbeneinheit 9 bis 11 ist separat als einstückiges Bauteil hergestellt und im Inneren des äußeren Pumpgehäuseteiles 8 verrastet. Die Pumpkolbeneinheit weist einen Kolbenkörper 9 auf, der in einem oberen Bereich einen Zylinderraum für ein koaxial angeordnetes, hubbewegliches Auslassventil 16 bildet. Das Auslassventil 16 ist durch eine Druckfederanordnung, vorliegend in Form einer nicht näher bezeichneten Schraubendruckfeder, in Schließrichtung so druckbelastet, dass das kolbenförmige Auslassventil 16 die Auslassöffnung 18 verschließt. Die Druckfederanordnung ist im Inneren des kolbenförmigen Auslassventils 16 angeordnet und stützt sich an einem Boden des Zylinderraumes des Kolbenkörpers 9 ab. Der Zylinderraum des Kolbenkörpers 9 ist in seinem oberen Randbereich mit einer umlaufenden Dichtlippe versehen, die sich umlaufend dicht an den Außenmantel des kolbenförmigen Auslassventils 16 anschmiegt. Dadurch ist der Zylinderraum und damit auch der Aufnahmeraum für die Druckfederanordnung gegen das Eindringen eines Mediums, insbesondere einer Flüssigkeit, abgedichtet. Das Auslassventil 16 ist zusätzlich als Füllstück ausgebildet, indem es das Innere des äußeren Pumpgehäuseteiles 8 nahezu vollständig ausfüllt. Auch der Kolbenkörper 9 ist als Füllkörper gestaltet, indem er mit seiner Außenkontur weitgehend an die Innenkontur des äußeren Pumpgehäuseteiles 8 angepasst ist.Relative to the fixed position on the media storage
In dem Kolbenkörper 9 ist ein erster Abschnitt einer zur Pumpkammer gehörenden Auslasskammer 17 gebildet, die zu dem Verdrängerraum 14 und der Dosierstrecke 13 hin offen ist. Dieser erste Abschnitt ist in seinem oberen Bereich radial nach außen hin offen und geht in einen Ringkammerabschnitt der Auslasskammer 17 über, der zwischen dem Außenmantel des Kolbenkörpers 9, der Außenkontur des Auslassventils 16 und der Innenkontur des äußeren Pumpgehäuseteiles 8 gebildet ist. Durch die Rastverbindung des Kolbenkörpers 9 in einem ringförmigen Rastflanschbereich mit dem äußeren Pumpgehäuseteil 8 ist der Ringkammerabschnitt axial nach unten geschlossen. Zur Auslassöffnung 18 hin verschließt das Auslassventil 16 den Ringkammerabschnitt der Auslasskammer 17.In the piston body 9, a first portion of a pump chamber belonging to the
In einem unteren Bereich bildet der Kolbenkörper 9 einen koaxial inneren Ventilkolben 10, der zusammen mit dem inneren Zylindermantel 4 im Bereich der Dosierstrecke 13 ein als Schieberventil gestaltetes Einlassventil für die Pumpvorrichtung bildet. Hierzu ist der Ventilkolben 10, der einstückig an dem Kolbenkörper 9 angeformt ist, in einem unteren Bereich mit einer ringförmigen Dosierlippe 12 versehen, die sich bei einem Eintauchen des Ventilkolbens 10 in die Dosierstrecke 13 dicht an eine Innenwandung des die Dosierstrecke 13 bildenden Dosierkanals anschmiegt. Der Durchmesser der Dosierlippe 12 ist größer als der Durchmesser des Ventilkolbens 10. Die Länge des Ventilkolbens 10 sowie der Hub des Kolbenkörpers 9 und damit der gesamten, hubbeweglichen Pumpeinheit sind so bemessen, dass die Dosierlippe 12 in einer oberen, in
Koaxial und in radialem Abstand ist der Ventilkolben 10 von einem glockenartigen Verdrängerkolben 11 umschlossen, der mittels eines unteren Dichtrandes umlaufend dicht an einer Innenwandung des ringförmigen Verdrängerraumes 14 anliegt. Der Querschnitt des glockenförmigen Verdrängerkolbens 11 ist an den Querschnitt des Verdrängerraumes 14 derart angepasst, dass in der nach unten bewegten Endposition des Kolbenkörpers nahezu kein Totraum im Verdrängerraum verbleibt, da der Verdrängerkolben 11 in dieser Position vollständig in den Verdrängerraum 14 eingetaucht ist. Auch der zwischen der Außenwandung des Ventilkolbens 10 und der Innenwandung des Verdrängerkolbens 11 verbleibende Ringraum ist in seinem Volumen auf das Körpervolumen des inneren Zylindermantels 4 abgestimmt, wodurch das verbleibende Totraumvolumen bei nach unten bewegter Pumpeinheit weiter reduziert ist. Das kolbenförmige Auslassventil 16 ist im Bereich seines Außenmantels mit mehreren Ringstufen versehen, die Druckangriffsflächen zum Öffnen des Auslassventils 16 bilden. Die Schutzkappe 19 weist eine sich konisch nach unten erweiternde Glockenform auf, die über einen oberen Formabschnitt des äußeren Pumpgehäuseteiles 8 gestülpt ist und auf einem Ringschulterabsatz des Pumpgehäuseteiles 8 axial zur Anlage kommt. Die Schutzkappe 19 wird manuell lösbar auf den Formabschnitt des Pumpgehäuseteiles 8 aufgerastet. Der Außendurchmesser der Schutzkappe 19 ist geringer als der maximale Außendurchmesser des Pumpgehäuseteils 8. Der obere Formabschnitt des Pumpgehäuseteils 8 ist als Nasenolive gestaltet, um eine Applikation eines in dem Medienspeicher enthaltenen Mediums in die Nase zu ermöglichen. Vorzugsweise ist in dem in dem Medienspeicher gelagerten Medium wenigstens ein pharmazeutischer Wirkstoff enthalten.Coaxially and at a radial distance, the
Auf einen Außenmantelbereich des äußeren Pumpgehäuseteiles 8 ist eine Betätigungshandhabe 20 aufgerastet, die an ihrer Oberseite wenigstens auf zwei gegenüberliegenden Seiten mit jeweils einer Fingerauflage versehen ist. In der Darstellung gemäß
Unterhalb des Raststeges 21 weist der Pumpgehäuseteil 8 einen zylindrischen Führungsmantel auf, der in seinem unteren Randbereich mit mehreren, über den Außenumfang des Führungsmantels auf gleicher Höhe verteilt angeordneten Anschlagnocken 23 versehen ist, die mit einem radial nach innen abragenden, umlaufenden Rastbund 24 des mantel- oder becherartigen Aufnahmeteiles 2 zusammenwirken. Die Rastnocken 23 und der Rastbund 24 bilden Rastprofilierungen, die eine Axialsicherung des hubbeweglichen Pumpgehäuseteils 8 an dem feststehenden Aufnahmeteil 2 gewährleisten. Die Rastprofilierungen 23, 24 bilden einen axialen Rückhalt des Pumpgehäuseteils 8 gegen die Druckkraft einer Pumpfederanordnung 15, die als Pumpantrieb für eine Rückstellung der hubbeweglichen Pumpeinheit in die in

Da der Verschlussdeckel 1 in Verbindung mit der zuvor beschriebenen Pumpvorrichtung ein als Medienspeicher dienendes Behältnis dicht abschließt, muss bei entsprechenden Pumpvorgängen ein Druckausgleich erfolgen, um die Funktion der Pumpvorrichtung nicht zu beeinträchtigen. Beim dargestellten Ausführungsbeispiel ist hierzu eine Druckausgleichsvorrichtung 25, 26, D vorgesehen, die in dem Verschlussdeckel 1 integriert ist. Die Druckausgleichsvorrichtung weist zum einen eine sich zur Außenseite hin stark verjüngende, als Druckausgleichsöffnung dienende Düsenbohrung D auf, deren engster Durchmesser vorzugsweise 0,2mm bis 0,3mm nicht übersteigt. Hierdurch wird ein Gasaustausch gewährleistet, ein Flüssigkeitsverlust hingegen ist aufgrund der äußerst kleinen Düsenbohrung D minimiert. Damit ergibt sich eine reduzierte Verdunstung. Die reduzierte Verdunstung ist insbesondere vorteilhaft für die in

Der Flüssigkeitsdruck drückt dann das Auslassventil 16 gegen die Druckkraft der Druckfederanordnung nach unten, wodurch über die Auslassöffnung 18 der entsprechende Austragvorgang des Mediums erfolgt. Die Auslassöffnung 18 ist vorzugsweise düsenförmig gestaltet, um eine Zerstäubung des ausgebrachten Mediums zu bewirken.
