Abstract

The cylindrical pump housing (13) which may be screwed on top of a bottle carries a stack of discs (22) above which projects the piston rod (15) of the pump. A cylindrical skirt (17) forming a cap (11), extends downwards from a flat top with a central opening connected by a side outlet to a dispensing nozzle projecting radially outwards. When the cap is pressed, the contents of the bottle are forced upwards through the central opening and through the nozzle due to the pumping action. The cap can be rotated about its vertical axis to control the discharge. In one position, the bottom of the skirt is blocked by the top disc, so that it cannot be pushed down. By rotating the cap until a vertical rib (19) inside is aligned with grooves (20,23) on the vertical outside faces of the discs, the cap can be pushed down.

Description

Die Erfindung betrifft eine handbetätigbare Austragpumpe für Medien, wie Flüssigkeiten, mit einem Pumpengehäuse und einem gegenüber diesem verschiebbaren Pumpdrücker, der als Kappe mit einem Kappenmantel einen Ringteil eines muffenförmigen Pumpenträgers axial verschiebbar übergreift, wobei an der Innenseite des Kappenmantels und am Außenumfang des Ringteiles ein Vorsprung und eine Anschlagschulter für diesen vorgesehen sind, die durch relative Verdrehung des Kappenmantels zwecks Einstellung des Pumphubes gegeneinander verstellbar sind.The invention relates to a manually operable discharge pump for media, such as liquids, with a pump housing and a pump pusher which can be displaced relative to it and which, as a cap with a cap jacket, engages axially slidably over a ring part of a sleeve-shaped pump carrier, a projection on the inside of the cap jacket and on the outer circumference of the ring part and a stop shoulder are provided for this, which are adjustable relative to each other by relative rotation of the cap shell for the purpose of adjusting the pump stroke.

Durch die FR-A-2 300 916 ist eine Austragpumpe bekannt, bei welcher die Anschlagschulter durch eine wendelförmige, kontinuierliche Steigungsfläche mit verhältnismäßig steiler Steigung gebildet ist, weshalb eine genaue Einstellung des Pumphubes kaum möglich ist und die Gefahr besteht, daß beim Auftreffen des zugehörigen Vorsprunges auf die Anschlagschulter eine so große Drehkraft auf den Pumpdrücker ausgeübt wird, daß sich dieser am Ende des eingestellten Pumphubes verdreht und ein größerer als der gewünschte Pumphub erfolgt. Es ist auch bekannt, für den Eingriff eines Vorsprunges mehrere über den Umfang verteilte Axialnuten vorzusehen, jedoch läuft in diesem Fall der Pumpdrücker innerhalb des Ringteiles, weshalb er den Vorsprung für den Eingriff in die Vertiefungen an seinem Außenumfang tragen muß. Eine solche Ausführung hat zahlreiche Nachteile, vor allem hinsichtlich der leichten Verschmutzung der Vertiefungen, was schnell zu ungenauen Hubwegen führt. Der vorstehende Vorsprung ist aber auch hinderlich, da man an ihm leicht hängen bleiben kann und außerdem kann er wegen seines Freiliegens leicht abgebrochen oder so beschädigt werden, daß seine bestimmungsgemäße Funktion nicht mehr sichergestellt ist.From FR-A-2 300 916 a discharge pump is known in which the stop shoulder is formed by a helical, continuous slope surface with a relatively steep slope, which is why an exact adjustment of the pump stroke is hardly possible and there is a risk that when the associated one hits Projection on the stop shoulder such a large torque is exerted on the pump handle that it rotates at the end of the set pump stroke and there is a larger than the desired pump stroke. It is also known to provide several circumferential axial grooves for the engagement of a projection, but in this case the pusher runs inside the ring part, which is why it has to carry the projection for engagement in the recesses on its outer circumference. Such a design has numerous disadvantages, especially with regard to the slight contamination of the depressions, which quickly leads to inaccurate stroke paths. The above projection is also a hindrance because it can easily get caught on it and, because of its exposure, it can easily be broken off or damaged so that its intended function can no longer be guaranteed.

Der Erfindung liegt die Aufgabe zugrunde, eine Austragpumpe der genannten Art zu schaffen, bei welcher auch bei kleiner Dimensionierung jeder der vorgegebenen Hubwege des Pumpdrückers ohne die Gefahr einer Selbstverstellung sicher und genau eingestellt werden kann und bei welcher die Vertiefungen trotzdem geschützt innerhalb des Kappenmantels liegen, wobei es ferner auf einfache Weise möglich sein soll, daß auf den Pumpdrücker nur sehr geringe Gleitreibungskräfte wirken.The invention has for its object to provide a discharge pump of the type mentioned, in which each of the predetermined stroke distances of the pump lever can be set safely and precisely without the risk of self-adjustment, and in which the depressions are nevertheless protected within the cap shell, even with small dimensions, it should also be possible in a simple manner that only very low sliding friction forces act on the pump handle.

Diese Aufgabe wird bei einer handbetätigbaren Austragpumpe der eingangs beschriebenen Art gemäß der Erfindung dadurch gelöst, daß mehrere axial gegeneinander versetzte Anschlagschultern vorgesehen und durch endseitige Querflächen mehrerer im Abstand zueinander um die Drehachse verteilter, axialnutförmiger Vertiefungen gebildet sind. Ein besonderer Vorteil ergibt sich bei dieser Lösung auch dadurch, daß die Gleitführung zwischen dem Kappenmantel und dem Pumpenträger nicht durch verhältnismäßig großflächige Umfangsflächen zu erfolgen braucht, sondern daß es hierfür ausreicht, wenn der oder die Vorsprünge lediglich an den Bodenflächen der Vertiefungen laufen, so daß sich trotz spielfreier Führung eine sehr geringe Gleitreibung ergibt. Dadurch eignet sich die erfindungsgemäße Ausbildung vor allem auch für Austragpumpen, die sehr klein dimensioniert und daher gegen Verkanten bei Betätigung recht empfindlich sind.This object is achieved in a manually operated discharge pump of the type described at the outset according to the invention in that a plurality of axially offset stop shoulders are provided and are formed by end transverse surfaces of a plurality of axially groove-shaped depressions spaced apart from one another about the axis of rotation. A particular advantage of this solution also results from the fact that the sliding guide between the cap casing and the bellhousing does not have to take place through relatively large circumferential surfaces, but that it is sufficient if the protrusion (s) only run on the bottom surfaces of the depressions, so that there is very little sliding friction despite the play-free guidance. As a result, the design according to the invention is particularly suitable for discharge pumps which are of very small dimensions and are therefore quite sensitive to tilting when actuated.

Eine besonders sichere und einfache Lagerung des Pumpdrückers sowie eine einfache Herstellung der Austragpumpe ergeben sich, wenn die Vertiefungen an mindestens einem Ringteil des Pumpenträgers und mindestens zwei rippenförmige Vorsprünge am Kappenmantel des Pumpdrückers vorgesehen sind.A particularly safe and simple mounting of the pump pusher and simple manufacture of the discharge pump result if the depressions are provided on at least one ring part of the pump carrier and at least two rib-shaped projections on the cap jacket of the pump pusher.

Nach einem weiteren Merkmal der Erfindung ist bei Drehlage des Vorsprunges in mindestens einer der Vertiefungen der Betätigungsdrücker in einer Arretierstellung gegen Betätigung gesperrt, so daß eine versehentliche Betätigung des Pumpdrückers in einfacher Weise vermieden werden kann.According to a further feature of the invention, when the projection is in the rotational position, the actuation pusher is locked in a locking position against actuation in at least one of the recesses, so that inadvertent actuation of the pump pusher can be avoided in a simple manner.

Ein versehentliches Abziehen des Betätigungsdrückers während der Verstellung seiner Drehlage läßt sich auf einfache Weise dadurch vermeiden, daß der jeweilige Vorsprung in Drehrichtung an einer in Umfangsrichtung an die jeweilige Vertiefung anschließenden, ebenfalls vertieften Umfangsfläche geführt ist, die zweckmäßig geringfügig geringer vertieft ist, so daß die Führung durch einen leichten Kontaktdruck mit einer vorbestimmten Reibhemmung erfolgt.Accidental pulling of the actuating button during the adjustment of its rotational position can be avoided in a simple manner in that the respective projection is guided in the direction of rotation on a circumferentially adjacent, also recessed peripheral surface, which is expediently slightly less deepened, so that the Guided by a slight contact pressure with a predetermined friction inhibition.

Bilden die Vertiefungen zusammen mit dem jeweiligen Vorsprung federnde Drehrasten, so ist die jeweilige Pumphub-Einstellung durch Rastung festgelegt, was mit sich bringt, daß sie einerseits leicht aufgefunden werden kann und andererseits kaum versehentlich zu verstellen ist.If the depressions form resilient rotary catches together with the respective projection, the respective pump stroke setting is determined by detent, which means that on the one hand it can be found easily and on the other hand it can hardly be adjusted accidentally.

Eine besonders einfache Handhabung der Austragpumpe ergibt sich, wenn der Pumpdrücker gegenüber dem Pumpenträger verdrehbar angeordnet und vorzugsweise die Anschlagschulter der längsten Vertiefung durch eine äußere Ringschulter des zugehörigen Ringteiles gebildet ist.A particularly simple handling of the discharge pump results if the pump pusher is arranged such that it can be rotated relative to the pump carrier and preferably the stop shoulder of the longest depression is formed by an outer ring shoulder of the associated ring part.

In weiterer Ausgestaltung der Erfindung wirkt mindestens ein Vorsprung bei Ausgangslage des Pumpdrückers mit einer sich nur über einen Teil eines Kreisumfanges erstreckenden, vertieften Umfangsfläche zusammen, von welcher die Vertiefungen ausgehen und deren beiden Enden die Drehbewegung des Vorsprunges begrenzen, wobei im Bereich eines Endes der Umfangsfläche eine die axiale Bewegung des Vorsprunges freigebende Vertiefung vorgesehen sein kann, so daß einerseits die Drehendlagen des Pumpdrückers genau festgelegt sind und andererseits die Drehlage, in welcher der Pumpdrücker axial zu betätigen ist, leicht aufgefunden werden kann.In a further embodiment of the invention, at least one projection cooperates with a recessed peripheral surface extending only over part of a circular circumference, from which the depressions originate and the two ends of which limit the rotary movement of the projection, in the region of one end of the peripheral surface a depression which releases the axial movement of the projection can be provided, so that on the one hand the rotational end positions of the pump pusher are precisely defined and on the other hand the rotational position in which the pump pusher is to be actuated axially can be easily found.

Bildet die Umfangsfläche in der Arretierstellung eine Rast für den Vorsprung, so ist dieser in der Arretierstellung noch besser gesichert.If the peripheral surface forms a catch for the projection in the locking position, then this is even better secured in the locking position.

Durch eine weitere Ausbildung ist es auch in vorteilhafter Weise möglich, daß der Vorsprung in der Arretierstellung gegen Abziehrichtung des Pumpdrückers gesichert in eine Ausnehmung eingreift, die vorzugsweise an ein Ende der Umfangsfläche anschließend durch die zugehörige, als Umfangsnut ausgebildete Vertiefung gebildet ist, so daß der Pumpdrücker in der Arretierstellung selbst bei größerer Belastung nicht versehentlich von der Austragpumpe abgedrückt werden kann.By further training it is also possible in an advantageous manner that the projection in the locking position against pulling direction of the pusher engages securely in a recess, which is preferably formed at one end of the peripheral surface by the associated, designed as a circumferential groove, so that the Pump pusher in the locking position cannot be inadvertently pressed off by the discharge pump, even with greater loads.

Besonders dann, wenn die Austragpumpe für durch den Benutzer wiederbefüllbare Behälter bestimmt ist, ist es vorteilhaft, wenn ein Aufschraubgewinde des Pumpenträgers zum Aufschrauben auf einen Behälter und die Anordnung der Umfangsfläche so getroffen sind, daß der Vorsprung sich beim Aufschrauben in der Arretierstellung befindet, so daß beim Aufschrauben eine axiale Betätigung des Pumpdrückers gesperrt ist.Particularly when the discharge pump is intended for containers that can be refilled by the user, it is advantageous if a screw thread of the pump support for screwing onto a container and the arrangement of the peripheral surface are such that the projection is in the locking position when screwed on, so that an axial actuation of the pump pusher is blocked when screwing on.

Zur Einstellung der Austragpumpe kann auch der Ringteil drehbar, vorzugsweise auf dem Pumpenträger, gelagert sein, so daß, insbesondere bei nichtzylindrischen Behältern, eine bestimmte bevorzugte Ausrichtung des Pumpdrückers gegenüber dem Behälter im wesentlichen aufrechterhalten werden kann.To adjust the discharge pump, the ring part can also be rotatably mounted, preferably on the pump support, so that, in particular in the case of non-cylindrical containers, a certain preferred alignment of the pump pusher with respect to the container can essentially be maintained.

Vor allem die zuletzt genannte Ausbildung ermöglicht es auch, daß in dem am Pumpenträger vorzugsweise begrenzt drehbar gelagerten Ringteil und in dem in Richtung auf den Pumpdrücker benachbarten Bereich des Pumpenträgers miteinander zum Fluchten zu bringende axiale Vertiefungen vorgesehen sind, in denen wenigstens ein innerer Vorsprung des in diesen Bereich eingreifenden Pumpdrückers laufen kann. Der gesonderte Ringteil ist auch bei einer Sicherung gegen Betätigung und/oder gegen Abziehen des Pumpdrückers vorteilhaft, weil dann die vorgegebene Sicherheits-Drehstellung unabhängig von der zum Beispiel durch ein Gewinde zufällig erfolgenden Stellung der Pumpe auf dem Behälter der Betätigungsdrücker beispielsweise zur Verpackung in eine bestimmte Lage gedreht werden kann. Dies kann vor allem dann wichtig sein, wenn sowohl der Behälter als auch der Pumpdrücker eine nicht rotationssymmetrische Form haben, also beispielsweise ein flacher oder eckiger Behälter mit einem Pumpdrücker mit seitlichem Vorsprung versehen wird.Above all, the last-mentioned design also makes it possible to provide axial recesses in the ring part, which is preferably rotatably mounted to a limited extent on the bellhousing, and in the region of the bellhousing adjacent to the pump lever, in which at least one inner projection of the in this area engaging pump trigger can run. The separate ring part is also advantageous for securing against actuation and / or against pulling off the pump pusher, because then the predetermined safety rotary position is independent of the position of the pump on the container of the actuation pusher, for example due to a thread, for example for packaging into a specific one Location can be rotated. This can be particularly important if both the container and the pump pusher have a non-rotationally symmetrical shape, for example a flat or square container is provided with a pump pusher with a lateral projection.

Bei allen beschriebenen Ausführungsformen können die Vorsprünge oder Ausnehmungen, worunter auch Schultern, Stufen, Anschlagflächen usw. zu verstehen sind, entweder am Pumpdrücker oder am Pumpengehäuse vorgesehen sein. Durch zumindest teilweise hinterschnittene Ausbildung der Vorsprünge bzw. Ausnehmungen kann der Pumpdrücker in einer einzigen vorgegebenen Drehstellung sowohl gegen Abziehen von der Pumpenkolbenstange wie auch gegen deren Betätigung gesichert werden, so daß nicht nur ein Verlust des Pumpdrückers, sondern auch eine Kontaminierung des Auslaßkanales der Pumpenkolbenstange sicher vermieden ist.In all of the described embodiments, the projections or recesses, which should also be understood to include shoulders, steps, stop surfaces, etc., can be provided either on the pump lever or on the pump housing. Through at least partially undercut design of the projections or recesses, the pump pusher can be secured in a single predetermined rotational position both against being pulled off the pump piston rod and against its actuation, so that not only loss of the pump pusher, but also contamination of the outlet channel of the pump piston rod is ensured is avoided.

Die erfindungsgemäße Austragpumpe ist insbesondere auch für pharmazeutische Produkte bzw. zur Ausgabe jeglicher fließfähiger Stoffe, wie flüssiger, gelartiger oder pastöser Medien geeignet. Mit der Austragpumpe kann dabei sehr genau dosiert und die dosierte Menge auch zerstäubt ausgebracht werden. Weitere Vorteile und Merkmale der Erfindung gehen auch aus den Unteransprüchen und der folgenden Beschreibung im Zusammenhang mit den Zeichnungen hervor. Die Merkmale der Unteransprüche sind einzeln oder in Kombination miteinander zweckmäßig und vorteilhaft.The discharge pump according to the invention is also particularly suitable for pharmaceutical products or for dispensing any flowable substances, such as liquid, gel-like or pasty media.

Further advantages and features of the invention also emerge from the subclaims and the following description in conjunction with the drawings.

In den Fig. 1 bis 3 ist eine Austragpumpe 11 dargestellt, die auf einen Behälter 12 aufgeschraubt ist. Die Austragpumpe 11 besitzt ein Pumpengehäuse 13, an dem ein nicht dargestellter, in den Behälter teilweise hineinragender Pumpenzylinder mit einer einfach wirkenden Kolbenpumpe vorgesehen ist. Eine Kolbenstange 15 der Pumpe ragt aus dem Pumpengehäuse nach oben heraus und auf sie ist als Betätigungsdrücker ein Pumpdrücker 14 aufgepreßt, der einen mit dem Auslaßkanal der hohl ausgebildeten Kolbenstange in Verbindung stehenden Auslaßkanal 27 enthält, welcher in einem Mündungsrohr seitlich über den übrigen, als umgekehrt topfförmiges Teil ausgebildeten Betätigungsdrücker hinausragt. Der Boden des Topfes wird von der Betätigungsdruckfläche 16 gebildet, auf die der Benutzer zur Betätigung der Pumpe in Richtung des Pfeiles 28 drückt.1 to 3, a discharge pump 11 is shown, which is screwed onto a container 12. The discharge pump 11 has a pump housing 13 on which a pump cylinder (not shown), which partially protrudes into the container, is provided with a single-acting piston pump. A piston rod 15 of the pump protrudes upwards out of the pump housing and a pump pusher 14 is pressed onto it as an actuating pusher, said pusher 14 containing an outlet channel 27 which is connected to the outlet channel of the hollow piston rod and which, in an orifice tube, laterally over the rest, and vice versa Pot-shaped part protruding push button protrudes. The bottom of the pot is formed by the actuating pressure surface 16, which the user presses in the direction of arrow 28 to actuate the pump.

Der zylindrische Kappenmantel 17 des Pumpdrückers 14 hat an seiner Innenfläche im vorliegenden Beispiel vier Vorsprünge 19 in Form axial verlaufender Rippen. Während der Kappenmantel 17 in seinem Innendurchmesser so bemessen ist, daß er über einen oberen zylindrischen Ringteil 21 des Pumpengehäuses herübergreift, sind die Vorsprünge 19 so bemessen, daß sie normalerweise an einer Stufe 29 in dem Ringteil 21 aufliegen. Es sind jedoch in gleicher Anordnung wie die Rippen 19 vier Vertiefungen 20 in dem Ringteil 21 in Form von längs verlaufenden Nuten vorgesehen, die die Vorsprünge 19 aufnehmen können.The cylindrical cap jacket 17 of the pump pusher 14 has four projections 19 in the form of axially extending ribs on its inner surface in the present example. While the cap jacket 17 is dimensioned in its inner diameter so that it extends over an upper cylindrical ring part 21 of the pump housing, the projections 19 are dimensioned such that they normally rest on a step 29 in the ring part 21. However, in the same arrangement as the ribs 19, four depressions 20 are provided in the ring part 21 in the form of longitudinal grooves which can accommodate the projections 19.

In einer Ringnut 24 des Pumpengehäuses ist ein Ringteil 22 von im wesentlichen L-förmiger Gestalt axial unverschiebbar, jedoch in Umfangsrichtung drehbar gelagert. Die Außenfläche seines in Achsrichtung verlaufenden L-Schenkels schließt an den Ringteil 21 übergangslos an und besitzt ebenfalls als axiale Nuten ausgebildete Vertiefungen 23, die durch Drehung des Ringteiles 22 fluchtend mit den Vertiefungen 20 ausgerichtet werden können (siehe Fig. 1). An dem nach außen vorstehenden L-Schenkel des Ringteiles 22 und dem angrenzenden Bereich des Pumpengehäuses 13 sind Markierungen 25 vorgesehen, die zwei Stellungen des Ringteiles 22 entsprechen. In diesen Stellungen kann der Ringteil 22 durch nicht näher dargestellte beliebige Anschläge die Begrenzung seiner Drehstellung finden. Es ist ferner möglich, den beiden Stellungen federnde Rasten zuzuordnen.In an annular groove 24 of the pump housing, an annular part 22 of essentially L-shaped shape is axially immovable, but is rotatably mounted in the circumferential direction. The outer surface of its L-leg extending in the axial direction connects seamlessly to the ring part 21 and also has recesses 23 designed as axial grooves, which can be aligned with the recesses 20 by rotating the ring part 22 (see FIG. 1). On the outwardly projecting L-leg of the ring part 22 and the adjacent area of the pump housing 13, markings 25 are provided, the two positions of the ring part 22 correspond. In these positions, the ring part 22 can find the limit of its rotational position by any stops (not shown). It is also possible to assign resilient detents to the two positions.

Die Wirkungsweise der Ausführung nach den Figuren 1 bis 3 ist wie folgt:The mode of operation of the embodiment according to FIGS. 1 to 3 is as follows:

In der in Fig. 1 dargestellten Stellung steht die Austragpumpe auf vollem Hub (kenntlich durch die Markierung "1"). Dabei fluchten die beiden Vertiefungen 20, 23 miteinander. Wenn jetzt der Pumpdrücker 14 heruntergedrückt wird, läuft der Vorsprung 19 in den fluchtenden Vertiefungen 20, 23 und kommt erst an der unteren Anschlagschulter 30 des Ringteiles 22 zum Anschlag. Dies entspricht dem vollen Pumpenhub.In the position shown in Fig. 1, the discharge pump is at full stroke (indicated by the mark "1"). The two depressions 20, 23 are aligned with one another. If the pump pusher 14 is now pressed down, the projection 19 runs in the aligned recesses 20, 23 and only comes to a stop at the lower stop shoulder 30 of the ring part 22. This corresponds to the full pump stroke.

In der Stellung nach Fig. 2 ist durch Drehen des Ringteiles 22 der halbe Hub eingestellt. Dabei sind die Vertiefungen 20 und 23 nicht in fluchtender Anordnung, so daß der Vorsprung 19 nun nur durch die Vertiefung 20 laufen kann und dann an der oberen Stirnfläche 26 des Ringteiles 22 zur Anlage kommt. Fig. 3 zeigt ebenfalls diese Stellung mit gegeneinander versetzten Vertiefungen 20, 23.In the position according to FIG. 2, half the stroke is set by rotating the ring part 22. The recesses 20 and 23 are not in alignment, so that the projection 19 can now only run through the recess 20 and then comes to rest on the upper end face 26 of the ring member 22. Fig. 3 also shows this position with mutually offset recesses 20, 23rd

Es ist noch zu bemerken, daß bei dieser Ausführung die Pumpe gänzlich blockiert werden kann, indem der Pumpdrücker 14 gegenüber dem Pumpengehäuse 13 so verdreht wird, daß die Vorsprünge 19 auf der Stufe 29 aufliegen, wenn sie nämlich nicht mit den Vertiefungen 20 fluchten. Dies ist eine Sicherungsstellung gegen ungewollte Betätigung der Pumpe.It should also be noted that in this embodiment the pump can be completely blocked by turning the pump pusher 14 relative to the pump housing 13 so that the projections 19 rest on the step 29 when they are not aligned with the recesses 20. This is a securing position against unintentional activation of the pump.

In Fig. 4 ist eine Ausführungsform dargestellt, die eine Einstellung in mehreren Stufen, nämlich den Stufen 0, 1/4, 1/2, 3/4, 1 gemäß den Markierungen 25a ermöglicht. Dazu ist ein Ringteil 22a vorgesehen, der an seinem Außenumfang eine Ausnehmung in Form einer Vertiefung 23a in der zylindrischen Wand des Ringteiles 22a hat, deren untere Fläche als Anschlagschultern 26a treppenförmig in fünf Stufen ansteigt. In Fig. 4 ist die Pumpe in der Stellung "0" dargestellt, in der ein Vorsprung 19a an der Innenfläche des zylindrischen Mantels des Pumpdrückers 14a auf der höchsten Stufe aufliegt. An dieser Stufe wird die Vertiefung 23a von einem Steg 31 übergriffen, so daß der Vorsprung 19a in der 0-Stellung den Pumpdrücker 14a an jeder axialen Bewegung, sowohl in Arbeitsrichtung, als auch gegen Abziehen des Betätigungsdrückers, sichert.FIG. 4 shows an embodiment which enables adjustment in several stages, namely the stages 0, 1/4, 1/2, 3/4, 1 according to the markings 25a. For this purpose, a ring part 22a is provided, which has on its outer circumference a recess in the form of a recess 23a in the cylindrical wall of the ring part 22a, the lower surface of which rises in five steps as stop shoulders 26a. In Fig. 4, the pump is shown in the position "0", in which a projection 19a rests on the inner surface of the cylindrical shell of the pump pusher 14a at the highest level. At this stage, the recess 23a is overlapped by a web 31, so that the projection 19a in the 0 position secures the pump pusher 14a against any axial movement, both in the working direction and against the actuation pusher being pulled off.

Um ein Verkanten des Pumpdrückers zu verhindern, kann die gleiche Anordnung auf der gegenüberliegenden Seite nochmals vorgesehen sein.In order to prevent the pump pusher from tilting, the same arrangement can be provided again on the opposite side.

Bei einer Verstellung auf einen beliebigen gewünschten Hubwert kann der Pumpdrücker 14a so weit herabgedrückt werden, bis der Vorsprung 19a auf der entsprechenden Anschlagschulter 26a aufliegt.When adjusted to any desired stroke value, the pump pusher 14a can be pushed down until the projection 19a rests on the corresponding stop shoulder 26a.

In den Fig. 5 und 6 ist eine Ausführung dargestellt, bei der der Pumpdrücker 14b im Bereich einer unteren Kante 32 ein System von Ausnehmungen und Stegen hat, das mit entsprechenden Vorsprüngen 19b an dem Pumpengehäuse 13 oder einem darauf gelagerten Ringteil zusammenwirkt.5 and 6, an embodiment is shown in which the pump pusher 14b has a system of recesses and webs in the region of a lower edge 32, which system cooperates with corresponding projections 19b on the pump housing 13 or an annular part mounted thereon.

Das System von Ausnehmungen ist am Innenumfang des Kappenmantels 17b des Pumpdrückers 14b angeordnet und besteht aus vier gleichen Systemeinheiten. Jede enthält eine in der Innenwand des Kappenmantels 17b vertiefte, axial verlaufende Vertiefung 33 in Form eines Schlitzes, an den sich eine etwas geringer vertiefte Umfangsfläche 34 im Bereich der unteren Kante 32 anschließt. Diese ist zur Kante 32 hin offen und nur in ihrem von der Vertiefung 33 entfernten Ende von einem Steg 35 so überdeckt, daß in diesem kurzen Bereich eine kanalartige Nut entsteht. In diesem Bereich ist eine Ausnehmung 36 in der Umfangsfläche 34 vorgesehen.The system of recesses is arranged on the inner circumference of the cap jacket 17b of the pump pusher 14b and consists of four identical system units. Each contains an axially extending recess 33 in the form of a slot, which is recessed in the inner wall of the cap jacket 17b and which is adjoined by a slightly less recessed peripheral surface 34 in the region of the lower edge 32. This is open towards the edge 32 and is only covered in its end remote from the recess 33 by a web 35 such that a channel-like groove is formed in this short area. In this area, a recess 36 is provided in the peripheral surface 34.

Die insgesamt vier Vorsprünge 19b sind in ihrer Breite und Tiefe so bemessen, daß sie mit leichtem Kontaktdruck in der Umfangsfläche 34 laufen können, während sie in der gegenüber der Umfangsfläche noch weiter vertieften Vertiefung 33 ohne Hindernis laufen können. In der letzteren Stellung kann die Pumpe betätigt werden. Wird dagegen der Pumpdrücker 14b in der Ruhestellung so verdreht, daß die Vorsprünge 19b in der Umfangsfläche 34 laufen, so ist die Pumpe gegen Betätigung gesperrt. Beim Weiterdrehen bis zum Ende 37 bzw. Anschlag laufen die Vorsprünge 19b in den kanalartigen Abschnitt der Umfangsfläche 34 ein, so daß der Pumpdrücker 14b durch den Steg 35 auch gegen Abnehmen gesichert ist. Die Ausnehmungen 36 bilden zusammen mit den Vorsprüngen 19b Rasten, die den Pumpdrücker 14b in dieser Lage federnd festlegen. Die Drehrichtung ist so gewählt, daß beim Aufschrauben der mit einem Schraubgewinde 42 (siehe Fig. 7) versehenen Pumpe auf einen Behälter der Pumpdrücker automatisch diese Sicherheits-Drehstellung, die in Fig. 6 dargestellt ist, einnimmt. Damit ist die Pumpe sofort nach ihrer Aufbringung auf den Behälter für den Transport gesichert.The total of four projections 19b are dimensioned in their width and depth in such a way that they can run in the peripheral surface 34 with slight contact pressure, while they can run in the recess 33, which is further deepened compared to the peripheral surface, without obstacle. The pump can be operated in the latter position. If, on the other hand, the pump pusher 14b is rotated in the rest position so that the projections 19b run in the peripheral surface 34, the pump is locked against actuation. When turning further to the end 37 or stop, the projections 19b run into the channel-like section of the peripheral surface 34, so that the pump pusher 14b is also secured against removal by the web 35. The recesses 36, together with the projections 19b, form catches which resiliently fix the pump pusher 14b in this position. The direction of rotation is selected so that when the pump, which is provided with a screw thread 42 (see FIG. 7), is screwed onto a container, the pump pusher automatically assumes this safety rotary position, which is shown in FIG. 6. This means that the pump is secured for transport as soon as it is placed on the container.

In Fig. 7 ist eine Ausführung dargestellt, die mit einem Pumpdrücker 14b nach den Fig. 5 und 6 arbeitet. Das Pumpengehäuse 13c enthält in diesem Falle als gesondert eingesetztes Teil den Pumpenzylinder 38. Unter Pumpengehäuse sind jedoch generell alle Teile der Pumpe zu verstehen, die gegenüber dem Behälter fest sind bzw. gegenüber denen sich der Pumpdrücker axial bewegt.FIG. 7 shows an embodiment which works with a pump trigger 14b according to FIGS. 5 and 6. In this case, the pump housing 13c contains the pump cylinder 38 as a separately inserted part. However, pump housing is generally understood to mean all parts of the pump that are fixed relative to the container or against which the pump pusher moves axially.

Am Pumpengehäuse 13c ist in einer ringförmigen Randausnehmung 39 ein Ringteil 22c eingesetzt und durch Einschnappen eines ringförmigen Wulstes 40 in eine entsprechende Nut gegen axiale Bewegung gesichert und in seiner Drehbewegung kontrolliert gebremst. Am Außenumfang des Ringteiles 22c, der mit dem Außenumfang des Pumpengehäuses 13c bündig ist, sind die vier Vorsprünge 19b angeformt, die mit den Vertiefungen 33 und den Umfangsflächen 34 zusammenarbeiten. Die Anordnung dieses gegen einen gewissen Widerstand drehbaren Ringteiles 22c ermöglicht es, den Pumpdrücker 14b in eine beliebige Lage zu drehen und von dieser Grundstellung aus die anhand der Fig. 5 und 6 beschriebenen Funktionen Pumpenbetätigung, gesperrte Betätigung und Sicherungsstellung auszuführen.On the pump housing 13c, an annular part 22c is inserted in an annular edge recess 39 and is secured against axial movement by snapping an annular bead 40 into a corresponding groove and its rotation is braked in a controlled manner. On the outer periphery of the ring part 22c, which is flush with the outer periphery of the pump housing 13c, the four projections 19b are formed, which cooperate with the depressions 33 and the peripheral surfaces 34. The arrangement of this ring part 22c, which can be rotated against a certain resistance, makes it possible to turn the pump pusher 14b into any position and, from this basic position, to perform the functions of pump actuation, blocked actuation and locking position described with reference to FIGS. 5 and 6.

Dies ist wichtig, um z. B. ein Mündungsrohr 18 in eine zum Transport geeignete Lage zu drehen und trotzdem den Pumpdrücker 14b in axialer Richtung zu sichern. Statt des Mündungsrohres könnte jedoch auch eine Zerstäuberdüse oder eine generell andere Gestaltung des Pumpdrückers verwendet werden.This is important to e.g. B. to turn a muzzle tube 18 into a suitable position for transport and still secure the pump pusher 14b in the axial direction. Instead of the mouth tube, however, an atomizing nozzle or a generally different design of the pump lever could also be used.
