Description

Stand der TechnikState of the art

Die Erfindung betrifft eine Austragvorrichtung zum Austrag von insbesondere pharmazeutischen Flüssigkeiten nach dem Oberbegriff von Anspruch 1.The invention relates to a discharge device for discharging in particular pharmaceutical liquids according to the preamble of claim 1.

Derartige Austragvorrichtungen sind aus dem Stand der Technik bekannt. Ihre Besonderheit liegt darin, dass bei aufgesetzter Kappe eine Betätigung nicht möglich ist. Somit wird insbesondere das versehentliche Betätigen wirksam verhindert.Such discharge devices are known from the prior art. Its peculiarity lies in the fact that an actuation is not possible when the cap is attached. Thus, in particular, the accidental operation is effectively prevented.

Eine derartige Austragvorrichtung ist beispielsweise aus der EP 1 051 262 B1 bekannt. Die dort gezeigte und beschriebene Austragvorrichtung weist an einer Kappe zwei Fortsätze auf, die sich durch Ausnehmungen eines Außengehäuses der Austragvorrichtung hindurch in diese hinein erstrecken und im aufgesetzten Zustand der Kappe eine Verlagerung der Betätigungshandhabe zumindest insoweit blockieren, dass kein vollständiger Austragvorgang möglich ist.Such a discharge device is for example from the EP 1 051 262 B1 known. The discharge device shown and described there comprises two extensions on a cap which extend through recesses of an outer housing of the discharge device into it and in the attached state of the cap block a displacement of the actuating handle at least to the extent that no complete discharge process is possible.

Die Austragvorrichtung der EP 1 051 262 B1 ist trotz der betätigungshindernden Wirkung der Kappe jedoch nicht als wirksamer Schutz vor einer missbräuchlichen Betätigung durch Kinder geeignet, da die Fortsätze an der Kappe die Nutzung eines komplexeren Kappentyps, beispielsweise eines kindergesicherten Drehverschlusses, verhindern. Die Gefahr ist daher groß, dass Kinder erfolgreich die Kappe vom Außengehäuse lösen oder durch Aufbringen einer hohen Kraft auf die Betätigungshandhabe die Kappe aus ihrer Schutzstellung abheben und somit Zugang zu der dann austragbaren pharmazeutischen Flüssigkeit erhalten können.The discharge of the EP 1 051 262 B1 However, despite the anti-actuation effect of the cap, it is not suitable as effective protection against abuse by children because the extensions on the cap prevent the use of a more complex cap type, such as a child-proof screw cap. The danger is therefore great that children successfully loosen the cap from the outer housing or by applying a high force on the actuating handle lift the cap from its protective position and thus can get access to the then liquid pharmaceutical liquid.

Aus der gattungsbildenden DE 29908923 U1 , Ausführungsbeispiel der Fig. 28, ist ein Spender bekannt, der einen Auslöseknopf aufweist, der bei Betätigung die Kraft einer vorgespannten Feder freigibt, so dass es zur Kompression einer Pumpkammer und damit zu einem Austragvorgang kommt. Der Auslösknopf ist für eine Betätigungsbewegung quer zur Austragrichtung vorgesehen. Ein mit dem Auslösknopf verbundener Sicherungssteg gestattet diese Bewegung jedoch nur, wenn eine Kappe des Spenders zuvor abgenommen wurde.From the generic DE 29908923 U1 , Embodiment of Fig. 28, a dispenser is known which has a release button, which releases the force of a prestressed spring when actuated, so that it comes to the compression of a pumping chamber and thus to a discharge process. The release button is provided for an actuating movement transversely to the discharge direction. However, a safety bar connected to the trigger button will allow this movement only if a cap of the dispenser has been previously removed.

Aus der FR 2682305 A1 , Ausführungsbeispiel der Fig. 6, ist ein Spender bekannt, der ebenfalls über einen radial beweglichen Auslöseknopf verfügt. Dieser ist erst nach Entfernen einer Kappe zugänglich. Weiterhin verfügt dieser Spender auch über in der Kappenbereich ragende Fortsätze, die bewirken, dass bei Aufsetzen der Kappe nach einem Austrag der Spender für den Folgeaustrag gespannt wird.From the FR 2682305 A1 , Embodiment of Fig. 6, a dispenser is known, which also has a radially movable release button. This is only accessible after removing a cap. Furthermore, this dispenser also has protruding projections in the cap area, which cause that when placing the cap after a discharge of the dispenser for the follow-up is stretched.

Aufgabe und LösungTask and solution

Aufgabe der Erfindung ist es, eine gattungsgemäße Austragvorrichtung dahingehende weiterzubilden, dass diese einen sichereren Schutz vor der missbräuchlichen Verwendung durch Kinder bietet und/oder eine flexiblere Verwendung von Kappentypen gestattet.The object of the invention is to develop a generic discharge pertinent to this, that they provide a safer protection provides for misuse by children and / or allows more flexible use of cap types.

Erfindungsgemäß wird dies durch eine Gestaltung einer Austragvorrichtung gemäß Anspruch 1 bewirkt.According to the invention this is effected by a design of a discharge device according to claim 1.

Bei einer erfindungsgemäßen Gestaltung ist vorgesehen, dass das Sperrglied, das der Wirkkopplung zwischen Kappe und Betätigungshandhabe dient, nicht kappenseitig vorgesehen ist, sondern stattdessen an der Betätigungshandhabe angebracht ist bzw. zumindest mit dieser zwangsgekoppelt ist. Nach Abnahme der Kappe bleibt das Sperrglied somit an der dann einsatzbereiten Austragvorrichtung und ist zumindest teilweise durch das Außengehäuse der Austragvorrichtung davor geschützt, beschädigt zu werden.In a design according to the invention it is provided that the locking member which serves the active coupling between the cap and actuating handle is not provided on the cap side, but instead is attached to the actuating handle or at least positively coupled with this. After removal of the cap, the locking member thus remains at the then ready for use discharge and is at least partially protected by the outer casing of the discharge from being damaged.

Das Sperrglied und die Ausnehmung im Außengehäuse, durch die das Sperrglied in den Kappenbereich hindurchragt, wenn die Betätigungshandhabe betätigt wird, sind derart an die Kappe angepasst, dass das Sperrglied dann, wenn die Kappe in ihrer Schutzstellung angeordnet ist, mit dieser kollidiert, sobald die Betätigungshandhabe betätigt wird und bevor ein vollständiger Austragvorgang bewirkt werden kann. Als Schutzstellung im Sinne der Erfindung wird die Endlage der Kappe beim Aufsetzen auf das Außengehäuse angesehen. Die Ausnehmung weist vorzugsweise eine Größe auf, die nur geringfügig größer ist als der Querschnitt des Sperrgliedes, da das Sperrglied durch die Ausnehmung vorzugsweise nur hindurchbewegt wird, ohne quer zur Erstreckungsrichtung innerhalb der Ausnehmung beweglich sein zu müssen.The locking member and the recess in the outer housing, through which the locking member protrudes into the cap portion when the actuating handle is actuated, are adapted to the cap, that the locking member, when the cap is disposed in its protective position, collides with this, as soon as the Actuating handle is actuated and before a complete discharge process can be effected. As a protective position in the context of the invention, the end position of the cap when placed on the outer housing is considered. The recess preferably has a size which is only slightly larger than the cross section of the locking member, since the locking member is preferably only moved through the recess, without having to be movable transversely to the extension direction within the recess.

Aufgrund der Tatsache, dass das Sperrglied nicht an der Kappe vorgesehen ist, bedarf es keiner speziellen Anforderung an die Kappe. Diese kann somit alle aus dem Stand der Technik üblichen Gestaltungen annehmen und insbesondere auch als dafür ausgebildet sein, durch eine andere als eine Linearbewegung auf das Außengehäuse aufgesetzt und von diesem abgenommen zu werden. So kann die Kappe beispielsweise als Gewindekappe ausgebildet sein, die ein Innengewinde aufweist, mit dem sie auf ein Außengewinde am Außengehäuse der Austragvorrichtung aufgeschraubt werden kann. Eine solche Gewindekappe stellt für Kleinkinder bereits eine erhebliche Hürde dar und ist insbesondere auch aufgrund der Selbsthemmung des Gewindes durch eine erhebliche Kraftbeaufschlagung der Betätigungshandhabe nicht zu überwinden.Due to the fact that the locking member is not provided on the cap, there is no special requirement for the cap. This can thus assume all customary from the prior art designs and in particular also be designed as by a other than a linear movement placed on the outer housing and to be removed from this. Thus, the cap may be formed, for example, as a threaded cap having an internal thread, with which it can be screwed onto an external thread on the outer housing of the discharge. Such a threaded cap already represents a considerable hurdle for toddlers and, in particular due to the self-locking of the thread by a considerable application of force to the actuating handle can not be overcome.

Die Fördereinrichtung einer erfindungsgemäßen Austragvorrichtung ist als Pumpe ausgebildet, die eine Pumpkammer aufweist, deren Inhalt durch eine Kraftbeaufschlagung der Betätigungshandhabe unter Druck gesetzt werden kann. Die Verlagerung der Betätigungshandhabe durch die manuelle Kraftbeaufschlagung erfolgt gegen die Kraft eine Rückhubfeder. Die Fördereinrichtung und die Rückhubfeder sind erfindungsgemäß Teil eines in die Austragvorrichtung eingesetzten Pumpspenders sein, der darüber hinaus auch den Flüssigkeitsspeicher umfasstThe conveyor of a discharge device according to the invention is designed as a pump having a pumping chamber, the content of which can be pressurized by a force applied to the actuating handle. The displacement of the actuating handle by the manual application of force takes place against the force of a return spring. According to the invention, the conveying device and the return stroke spring are part of a pump dispenser inserted in the discharge device, which also comprises the liquid storage device

Von besonderem Vorteil ist es, wenn die Gewindekappe als Sicherheitsgewindekappe ausgebildet ist und als solche einen Innenabschnitt mit Gewinde und einen von außen zugänglichen Außenabschnitt aufweist, wobei der Außenabschnitt zur drehfesten Kopplung mit dem Innenabschnitt axial gegenüber dem Innenabschnitt verlagerbar ist. Hierdurch wird ein erhöhtes Maß an Sicherheit erreicht, welches es Kindern und insbesondere Kleinkindern besonders erschwert, Medium aus der Austragvorrichtung auszutragen.It is particularly advantageous if the threaded cap is designed as a safety threaded cap and as such has an inner threaded portion and an externally accessible outer portion, the outer portion being axially rotatable relative to the inner portion for rotationally fixed coupling with the inner portion. As a result, an increased level of security is achieved, which makes it particularly difficult for children and especially infants to discharge medium from the discharge device.

Von besonderem Vorteil ist es weiterhin, wenn das Sperrglied derart ausgebildet ist, dass es sowohl in der betätigten als auch in der unbetätigten Relativstellung der Betätigungshandhabe zum Außengehäuse zumindest abschnittsweise in der Ausnehmung des Außengehäuses angeordnet ist. Hierdurch ist die Ausnehmung stets verschlossen, sodass ein Eindringen von Schmutz verhindert wird. Insbesondere wird durch eine derartige permanente Anordnung des Sperrgliedes in der Ausnehmung erreicht, das nach der Einführung des Sperrgliedes in die Ausnehmung während des Montagevorgangs keine weiteren Einführvorgänge während des Betriebes erforderlich sind, sodass ein etwaiges Verkanten des Sperrgliedes an der Ausnehmung nicht zu befürchten ist.It is furthermore of particular advantage if the locking member is designed such that it is at least partially in the recess of the outer housing both in the actuated and in the unactuated relative position of the actuating handle to the outer housing is arranged. As a result, the recess is always closed, so that penetration of dirt is prevented. In particular, is achieved by such a permanent arrangement of the locking member in the recess, which after the introduction of the locking member into the recess during the assembly process no further insertion operations are required during operation, so that any tilting of the locking member to the recess is not to be feared.

Das Sperrglied kann durch die Betätigungshandhabe mittelbar bewegt werden, beispielsweise um eine von der Betätigungshandhabe abweichenden Bewegungsgeschwindigkeit oder eine abweichende Bewegungsrichtung aufzuweisen. Als besonders vorteilhaft wird es jedoch angesehen, wenn das Sperrglied ortsfest zu Betätigungshandhabe and dieser angebracht ist oder sogar einstückig an einem Hauptabschnitt der Betätigungshandhabe angeformt ist, da somit eine besonders unmittelbare Wirkung der Kappe in ihrer Schutzstellung auf die Bewegbarkeit der Betätigungshandhabe erzielt wird. Bei solchen Gestaltungen folgt das Sperrglied stets unmittelbar der Bewegung der Betätigungshandhabe. Sobald das Sperrglied aufgrund einer aufgesetzten Kappe nicht weiter bewegt werden kann, endet auch die Möglichkeit, die Betätigungshandhabe weiter zu bewegen, so dass ein Austragvorgang nicht erzielt werden kann.The locking member can be moved indirectly by the actuating handle, for example, to have a deviating from the actuating handle movement speed or a different direction of movement. However, it is considered to be particularly advantageous if the blocking member is attached stationary to actuating handle and this is even integrally formed on a main portion of the actuating handle, since thus a particularly direct effect of the cap is achieved in its protective position on the mobility of the actuating handle. In such designs, the locking member always follows directly the movement of the actuating handle. As soon as the locking member can not be moved further due to an attached cap, the possibility also ends that the actuating handle continues to move, so that a discharge process can not be achieved.

Von besonderem Vorteil ist weiterhin, wenn zwei Sperrglieder vorgesehen sind, die sich zumindest in der betätigten Stellung der Betätigungshandhabe jeweils durch bezogen auf die Austragöffnung gegenüberliegende Ausnehmungen im Außengehäuse erstrecken. Durch diese Gestaltung mit zwei Sperrgliedern wird ein höheres Maß an Sicherheit erreicht. Von besonderem Vorteil ist eine Gestaltung, bei der am Außengehäuse bezogen auf die Austragöffnung gegenüberliegend zueinander zwei Fingerauflageflächen vorgesehen sind, wobei die Fingerauflageflächen in Umfangsrichtung versetzt zu den Ausnehmungen angeordnet sind, vorzugsweise um 90° versetzt.Of particular advantage is further, if two locking members are provided which extend at least in the actuated position of the actuating handle in each case by relative to the discharge opening opposite recesses in the outer housing. This design with two locking members a higher degree of security is achieved. Of particular advantage is a design in which the outer housing relative to the discharge opening opposite each other two finger support surfaces are provided, wherein the finger support surfaces offset in the circumferential direction to the recesses are arranged, preferably offset by 90 °.

The pumping device 54 is designed to be actuated by a relative displacement of the outlet nozzle 56 against the force of a return spring provided in the pump dispenser in the direction of the liquid reservoir 52. The outlet port 56 is inserted into an extension piece 16, which is integrally formed on the housing 10. Within the extension piece 16, a liquid channel 18 which leads to a discharge opening 20 extends.

Die Austragvorrichtung ist dafür ausgebildet, dass durch eine mittels manueller Kraftbeaufschlagung bewirkte Verlagerung der Betätigungshandhabe 30 und damit des Flüssigkeitsspeichers 52 des Pumpspenders 50 gegenüber dem Gehäuse 10 und damit dem im Gehäuse 10 fest fixierten Auslassstutzen 56 ein Austragvorgang erzielt wird. Durch die dabei fortschreitende Verlagerung der Betätigungshandhabe wird eine Pumpkammer im Pumpspender 50 kontinuierlich komprimiert, so dass Flüssigkeit aus der Pumpkammer in Richtung des Auslassstutzens 56 herausgedrückt wird. Die durch den Auslassstutzen 56 ausgebrachte Flüssigkeit strömt in den Kanal 18 und wird so bis zur Austragöffnung 20 gefördert.The discharge device is designed such that by means of a manual application of force caused displacement of the actuating handle 30 and thus of the liquid reservoir 52 of the pump dispenser 50 relative to the housing 10 and thus the housing 10 fixedly fixed outlet nozzle 56 a discharge process is achieved. As a result of the progressive displacement of the actuating handle, a pumping chamber in the pump dispenser 50 is continuously compressed, so that fluid is forced out of the pumping chamber in the direction of the outlet connection 56. The discharged through the outlet port 56 liquid flows into the channel 18 and is thus conveyed to the discharge opening 20.

Wie insbesondere aus der Darstellung der Fig. 1 und der Fig. 2a, linke Seite, hervorgeht, sind am Betätigungsabschnitt 30 zwei Fortsätze 32 einstückig angebracht, die sich in Richtung von Ausnehmungen 22 des Gehäuses 10 erstrecken. Im gesicherten Zustand der Fig. 2a sowie im entsicherten und unbetätigtem Zustand der Fig. 2b ragen diese Fortsätze 32 nicht über die Ausnehmungen 22 nach außen hinaus.As in particular from the representation of Fig. 1 and the Fig. 2a Left side, are shown, two extensions 32 are integrally mounted on the actuating portion 30, which extend in the direction of recesses 22 of the housing 10. In the secured state of Fig. 2a as well as in the unlocked and unactuated state of Fig. 2b these projections 32 do not protrude beyond the recesses 22 to the outside.

Zur Sicherung der Austragvorrichtung der Fig. 1 und 2a bis 2c ist eine Sicherheitskappe 70 vorgesehen. Diese ist als Schraubkappe ausgebildet und weist hierfür ein Innengewinde 72 auf, welches zum Zusammenwirken mit einem am Gehäuse 10 vorgesehenen Außengewinde 24 ausgebildet ist.To secure the discharge of the Fig. 1 and 2a to 2c a safety cap 70 is provided. This is designed as a screw cap and has for this purpose an internal thread 72, which cooperates is formed with an external thread 24 provided on the housing 10.

Das Innengewinde 72 ist an einem Innenbauteil 74 der Kappe 70 vorgesehen. Das Innenbauteil ist von außen nicht unmittelbar zugänglich, sondern durch ein Außenbauteil 76 abgeschirmt. Dieses Außenbauteil 76 ist in Richtung des Pfeils 4 gegenüber dem Innenbauteil 74 verlagerbar. An der Stirnseite 75 des Innenbauteils 74 sowie der korrespondierenden Innenseite 78 des Außenbauteils 76 sind formschlüssig zusammenwirkende Fortsätze und Ausnehmungen angebracht, die bei Kraftbeaufschlagung des Außenbauteils 76 in Richtung des Innenbauteils 74 einen Formschluss bewirken, durch den die beiden Bauteile 74, 76 drehfest miteinander verbunden sind, sodass durch Verdrehen des Außenbauteils 76 um die durch den Pfeil 4 definierte Achse auch das Innenbauteil 74 verdreht werden kann und die Kappe 70 somit in Ihrer Gesamtheit vom Außengewinde 24 des Gehäuses 10 abgeschraubt werden kann.The internal thread 72 is provided on an inner component 74 of the cap 70. The inner component is not directly accessible from the outside, but shielded by an outer member 76. This outer component 76 is displaceable in the direction of the arrow 4 relative to the inner component 74. On the end face 75 of the inner member 74 and the corresponding inner side 78 of the outer member 76 positively co-operating projections and recesses are mounted, which cause a positive engagement with force of the outer member 76 in the direction of the inner member 74 through which the two components 74, 76 are rotatably connected to each other , so that by rotating the outer member 76 about the axis defined by the arrow 4 and the inner member 74 can be rotated and the cap 70 thus can be unscrewed in its entirety from the external thread 24 of the housing 10.

Das Innenbauteil 74 weist auf seiner zum Gehäuse 10 hinweisenden Seite einen umlaufenden Sicherungsflansch 77 auf. Dieser kommt im gesicherten Zustand der Fig. 2a zum Anliegen auf der Oberfläche des Gehäuses 10. Dabei ist der Flansch so geformt, dass er in der Schutzstellung der Kappe 70 der Fig. 2a unmittelbar oberhalb der Ausnehmungen 22 angeordnet ist.The inner component 74 has on its side facing the housing 10 a circumferential securing flange 77. This comes in the secured state of Fig. 2a To the concern on the surface of the housing 10. In this case, the flange is shaped so that it in the protective position of the cap 70 of Fig. 2a is arranged directly above the recesses 22.

Dies bewirkt, dass in der in Fig. 2a dargestellten Schutzstellung der Kappe 70 eine Bewegung des Betätigungsabschnittes 30 in Richtung des Pfeils 2a gegenüber dem Gehäuse 10 blockiert ist. Eine Verlagerung des Betätigungsabschnitts 30 wird dadurch unterbunden, dass im Zuge einer solchen Verlagerung die Fortsätze 32 mit der Kappe 70, genauer mit dem Sicherungsflansch 77, kollidieren. Bei aufgesetzter Kappe 70 ist somit kein Austragvorgang zu bewirken.This causes in the in Fig. 2a illustrated protective position of the cap 70 is a movement of the actuating portion 30 in the direction of the arrow 2a with respect to the housing 10 is blocked. A displacement of the actuating portion 30 is thereby prevented that in the course of such a displacement, the extensions 32 with the cap 70, more precisely with the securing flange 77, collide. When attached cap 70 thus no discharge operation is to effect.

Erst wenn die Kappe 70 abgeschraubt wurde und dadurch der Zustand der Fig. 2b erzielt wurde, ist es möglich, durch eine Kraftbeaufschlagung des Betätigungsabschnittes 30 in Richtung des Pfeils 2a den Betätigungsabschnitt 30 gegenüber dem Gehäuse 10 zu verlagern, sodass hierdurch ein Austragvorgang in der oben beschriebenen Art und Weise erreicht wird, also ein Sprühstrahl 8 durch die Austragöffnung 20 erfolgt. Wie die linke Darstellung der Fig. 2c zeigt, werden während des Austragvorgangs die Sperrglieder 32 nach oben aus den Ausnehmungen 22 herausgeschoben, wobei dies aufgrund der entfernten Kappe 70 ungehindert möglich ist.Only when the cap 70 has been unscrewed and thereby the state of Fig. 2b has been achieved, it is possible, by applying force to the actuating portion 30 in the direction of the arrow 2a to shift the actuating portion 30 relative to the housing 10, so that a discharge process in the manner described above is achieved, ie a spray jet 8 through the discharge port 20th he follows. Like the left illustration of the Fig. 2c shows, during the Austragvorgangs the locking members 32 are pushed up out of the recesses 22, which is possible due to the removed cap 70 unhindered.
