Description

Die Erfindung bezieht sich auf einen Betätigungskopf einer Saug-Druck-Pumpe zum Ausspritzen eines Produkts aus einem Behältnis, der einen zu einer Ausspritzöffnung führenden Auslaßkanal aufweist, in dem ein durch eine Feder belastetes Verschlußstück angeordnet ist, wobei das Verschlußstück in seiner Schließstellung die Ausspritzöffnung unter der Kraft der Feder unmittelbar abdichtet und durch den bei Betätigung der Saug-Druck-Pumpe ausgeübten Druck des Produkts dessen Durchfluß durch den Auslaßkanal und durch die Ausspritzöffnung gegen die Kraft der Feder freigibt, und wobei ein sich an die Ausspritzöffnung anschließender erster Auslaßkanalabschnitt von einem Rohr umgeben ist, in dem das Verschlussstück abgedichtet verschiebbar geführt ist und das in eine Bohrung im Körper des Betätigungskopfes eingesetzt ist, die zwischen sich und dem Rohr einen einen zweiten Auslaßkanalabschnitt bildenden Ringraum begrenzt, der über einen dritten, die Wand des Rohres durchquerenden Auslaßkanalabschnitt mit dem ersten Auslaßkanalabschnitt verbunden ist.The invention relates to an actuating head of a suction-pressure pump for ejecting a product from a container having a leading to an ejection outlet outlet channel in which a loaded by a spring closure member is arranged, wherein the closure piece in its closed position, the ejection opening under the force of the spring directly seals and released by the pressure exerted by the pressure of the product on actuation of the suction pressure product of the flow through the outlet channel and through the ejection opening against the force of the spring, and wherein a subsequent to the ejection opening first outlet channel of a pipe is surrounded, in which the closure piece is sealingly slidably guided and which is inserted into a bore in the body of the actuating head, which defines between itself and the tube a second outlet channel forming annular space through a third, the wall of the tube durchque ing outlet duct section is connected to the first outlet channel section.

Bei einem bekannten Betätigungskopf dieser Art ( DE 201 03 144 U1 ) erstreckt sich ein Auslaßkanalabschnitt durch den Körper des Betätigungskopfes hindurch bis in einen sich an die Austrittsöffnung anschließenden zylindrischen Raum in einer Bohrung des Körpers, in der das Verschlußstück abgedichtet geführt ist. Die Ausbildung dieses Auslaßkanalabschnitts ist aufwendig. Sie erfordert ein kompliziertes Formwerkzeug, wenn der Körper des Betätigungskopfes, wie üblich, aus thermoplastischem Kunststoff hergestellt wird. Zusätzlich erfordert er eine zweiteilige Ausbildung des Körpers, dessen Teile dicht miteinander verbunden werden müssen, sei es durch Schweißen oder Kleben, was zeit- und arbeitsaufwendig ist.In a known actuator head of this type ( DE 201 03 144 U1 ) extends a Auslaßkanalabschnitt through the body of the actuating head through to a subsequent to the outlet opening cylindrical space in a bore of the body in which the closure piece is guided sealed. The formation of this outlet channel section is expensive. It requires a complicated mold when the body of the actuator head, as usual, made of thermoplastic material. In addition, it requires a two-part construction of the body, the parts of which must be sealed together, whether by welding or gluing, which is time consuming and laborious.

Bei einem anderen bekannten Betätigungskopf ( DE 27 09 796 B2 ) ist das Verschlußstück als Ventilschieber ausgebildet, der quer zu einer Einlaßöffnung eines zwischen dem Verschlußstück und der Ausspritzöffnung liegenden Auslaßkanals verschiebbar ist. Der Ausspritzöffnung ist eine Wirbelkammer in dem Auslaßkanal vorgeschaltet. Über die Ausspritzöffnung steht der Auslaßkanal in jeder Lage des Verschlußstücks mit der Umgebung in Verbindung. Ein nicht vollständig aus dem Auslaßkanal ausgestoßener Produktrest kann daher mit kontaminierenden und schädlichen, in der Außen- bzw. Umgebungsluft enthaltenen Keimen, Bakterien oder Viren sowie mit aggressiven, für das Produkt schädlichen Gasen, insbesondere Luftsauerstoff, in Berührung kommen. Derart schädliche Einflüsse sind besonders dann unerwünscht oder gefährlich, wenn es sich bei dem Produkt um ein Nahrungsmittel, ein Medikament, Deodorant oder ein anderes Produkt handelt, das vom Menschen ein- oder aufgenommen wird, selbst wenn nur ein geringer kontaminierter Produktrest im Betätigungskopf verbleibt. Ein solcher kontaminierter Produktrest könnte bei der nächsten Betätigung nach längerer Nichtbetätigung mit ausgespritzt werden und die Gesundheit des Benutzers gefährden.In another known actuator head ( DE 27 09 796 B2 ), the closure piece is designed as a valve slide, which is displaceable transversely to an inlet opening of a lying between the closure piece and the ejection opening outlet channel. The ejection opening is preceded by a vortex chamber in the outlet channel. About the ejection opening of the outlet channel is in any position of the closure piece with the environment in connection. A product residue that is not completely ejected from the outlet channel can therefore come into contact with contaminating and harmful germs, bacteria or viruses contained in the outside or ambient air and with aggressive gases which are harmful to the product, in particular atmospheric oxygen. Such deleterious effects are particularly undesirable or dangerous if the product is a food, drug, deodorant, or other product that is ingested or ingested by humans, even if only a small amount of contaminated product remains in the actuator head. Such a contaminated product residue could be ejected at the next operation after prolonged non-operation with and endanger the health of the user.

In NL-A-6918423 sind unterschiedliche Bauformen von Betätigungsköpfen für Saug-Druck-Pumpen zum Ausspritzen eines Produkts aus einem Behältnis offenbart. Zum Verschluss der Ausgabeöffnung für das Produkt dient ein federbelasteter Verschlusskörper, der in einen korrespondierenden Aufnahmeraum im Betätigungskopf eingesetzt ist. Der Verschlusskörper weist an Teilen seiner Außenseite eine schraubenförmig ausgebildete Furche aus, durch die das auszugebende Produkt hindurch treten kann, da das Produkt in einem hinteren Bereich des Verschlusskörpers aus dem Behälter gefördert wird, der sich entfernt zur Ausgabeöffnung befindet. In einem vorderen Bereich ist der Verschlusskörper kegelförmig geformt, so dass dieser mit Hilfe der Feder die Ausgabeöffnung verschließen kann. Gemäß einer der vorgeschlagenen Bauausführungen wird vorgeschlagen, dass der Verschlusskörper mitsamt der Ausgabeöffnung und dem, den Verschlusskörper aufnehmenden Aufnahmebereich, als vorgefertigte Baueinheit in eine korrespondierende, im Betätigungskopf vorgesehene Ausnehmung eingesetzt werden kann. Um eine fluidische Verbindung zwischen dem Behälter und dem den Verschlusskörper aufnehmenden Aufnahmebereich herzustellen, ist zwischen der Ausnehmung im Betätigungskopf und der Baueinheit mit dem Verschlusskörper ein ringförmiger Verbindungsraum vorgesehen.In NL-A-6918423 different types of actuator heads for suction-pressure pumps for ejecting a product from a container are disclosed. A spring-loaded closure body, which is inserted into a corresponding receiving space in the actuating head, serves to close the product discharge opening. The closure body has, on parts of its outer side, a helically formed groove through which the product to be dispensed can pass, as the product in a rear region of the closure body is conveyed out of the container, which is remote from the dispensing opening. In a front region of the closure body is conically shaped so that it can close the output opening by means of the spring. According to one of the proposed building designs, it is proposed that the closure body, together with the dispensing opening and the receiving area receiving the closure body, can be inserted as a prefabricated structural unit into a corresponding recess provided in the actuating head. In order to establish a fluidic connection between the container and the receiving body receiving the closure body, an annular connecting space is provided between the recess in the actuating head and the structural unit with the closure body.

Der Erfindung liegt die Aufgabe zugrunde, einen Betätigungskopf der eingangs geschilderten Art anzugeben, der einfacher herstellbar und bei dem die Gefahr einer Kontaminierung des Produkts weitgehend vermieden ist.The invention has for its object to provide an actuating head of the type described, the easier to produce and in which the risk of contamination of the product is largely avoided.

Erfindungsgemäß ist diese Aufgabe bei einem Betätigungskopf der eingangs geschilderten Art dadurch gelöst, daß das Verschlußstück aus gummielastischem Material mit einem Übermaß des Endabschnitts gegenüber dem Durchmesser der Ausspritzöffnung besteht.According to the invention, this object is achieved in an actuating head of the type described above in that the closure piece is made of rubber-elastic material with an excess of the end portion relative to the diameter of the ejection opening.

Bei dieser Lösung werden die drei erwähnten Auslaßkanalabschnitte durch die Bohrung und das Rohr begrenzt, das lediglich in die Bohrung dicht eingesetzt zu werden braucht. Die Formgebung des Betätigungskopfes ist daher sehr einfach, und zwar unabhängig von seinem Material, das vorzugsweise aus thermoplastischem Kunststoff besteht. Ferner kann weder in der Offenstellung noch in der Schließstellung des Verschlußstücks ein im Auslaßkanal vorhandener Produktrest kontaminiert werden: In der nur kurzzeitig andauernden Offenstellung bei der Produktausgabe würde er weitgehend ausgestoßen, und in der Schließstellung ist der Auslaßkanal nach außen hin völlig durch das Verschlußstück abgesperrt. Ein im Auslaßkanal verbliebener Produktrest kann daher nicht mit schädlichen Keimen, Bakterien, Viren usw. sowie mit schädlichen Materialien, wie Gasen, insbesondere Luftsauerstoff, in Berührung kommen. Außerdem legt sich der Endabschnitt der Kolbenstange in der Schließstellung des Verschlußstücks besonders fest in der Ausspritzöffnung an. Dies ergibt eine besonders hohe Dichtwirkung des Endabschnitts in der Ausspritzöffnung.In this solution, the three mentioned Auslaßkanalabschnitte are limited by the bore and the tube, which only needs to be used tightly into the bore. The shape of the actuating head is therefore very simple, regardless of its material, which preferably consists of thermoplastic material. Furthermore, neither in the open position nor in the closed position of the closure a present in the outlet channel product residue can be contaminated: In the short-term continuous open position in the product output, he would largely expelled, and in the closed position, the outlet channel is completely closed to the outside by the closure member. One in the outlet channel residual product residue can therefore not come into contact with harmful germs, bacteria, viruses, etc., as well as with harmful materials, such as gases, in particular atmospheric oxygen. In addition, the end portion of the piston rod sets particularly firmly in the ejection opening in the closed position of the closure piece. This results in a particularly high sealing effect of the end portion in the ejection opening.

Vorzugsweise ist dafür gesorgt, daß das Verschlußstück einen gegen die Innenseite des Auslaßkanals dichtenden Kolben mit einer Kolbenstange aufweist, die in der Schließstellung des Verschlußstücks mit einem Endabschnitt dicht in die Ausspritzöffnung ragt. Hierbei wirkt das Verschlußstück nicht nur als solches, sondern auch als Druckkolben, der das nach der Betätigung der Saug-Druck-Pumpe durch den Betätigungskopf im Auslaßkanal verbliebene Produkt unter der Kraft der Feder durch die Ausspritzöffnung ausspritzt und dabei gleichzeitig die Ausspritzöffnung absperrt.Preferably, it is ensured that the closure piece has a piston sealing against the inside of the outlet channel with a piston rod which projects in the closed position of the closure piece with an end portion tightly into the ejection opening. Here, the closure piece acts not only as such, but also as a pressure piston which ejects the product remaining after actuation of the suction-pressure pump by the actuating head in the outlet channel under the force of the spring through the ejection opening while blocking the ejection opening.

Ferner kann der an den Endabschnitt angrenzende Abschnitt der Kolbenstange einen größeren Durchmesser als die Ausspritzöffnung haben und in der Schließstellung des Verschlußstücks am inneren Rand der Ausspritzöffnung unter der Kraft der Feder anliegen. Der den größeren Durchmesser aufweisende Abschnitt der Kolbenstange legt sich dabei während der Schließbewegung des Verschlußstücks unter der Kraft der Feder mit seiner vom größeren zum kleineren Durchmesser übergehenden Schulterfläche zusätzlich abdichtend am inneren Rand der Ausspritzöffnung an. Gleichzeitig wird dadurch die Schließbewegung begrenzt.Further, the adjacent to the end portion portion of the piston rod may have a larger diameter than the ejection opening and bear in the closed position of the closure member at the inner edge of the ejection opening under the force of the spring. The section of the piston rod having the larger diameter lays down during the closing movement of the closure piece under the force of the spring with its shoulder surface passing from the larger to the smaller diameter in an additional sealing manner on the inner edge the ejection opening on. At the same time this limits the closing movement.

Vorzugsweise weist der Kolben eine umlaufende Dichtlippe auf, die einen Durchtritt des Produkts nur in Richtung zur Ausspritzöffnung zuläßt. Die Dichtlippe ermöglicht einerseits den Durchtritt von Luft aus der Federkammer in den Auslaßkanal bei der erstmaligen Betätigung des Betätigungskopfes, so daß im wesentlichen nur die Federkraft durch den Produktdruck während der Produktausgabe zu überwinden ist. Die dabei aus der Federkammer in den Auslaßkanal eingedrungene Luft würde sich bei der erstmaligen Betätigung dann zwar teilweise mit der ausgegebenen und bei der nächsten Betätigung auszugebenden Produktmenge vermischen. Bei der zweiten und jeder folgenden Betätigung würde jedoch keine weitere Luft aus der Federkammer in den Auslaßkanal gelangen, weil ihr Überdruck bereits abgebaut ist und die Dichtlippe den Luftdurchtritt nur in der einen Richtung und damit kein erneutes Eindringen von Luft in die Federkammer zuläßt. Desgleichen wird ein Eindringen des Produkts über die Dichtlippe hinweg in die Federkammer verhindert.Preferably, the piston has a circumferential sealing lip, which allows a passage of the product only in the direction of the ejection opening. The sealing lip allows on the one hand, the passage of air from the spring chamber in the outlet channel at the first actuation of the actuating head, so that essentially only the spring force is overcome by the product pressure during product dispensing. The case thereby penetrated from the spring chamber into the outlet air would then be partially mixed with the output and to be issued at the next operation amount of product during the first operation. In the second and each subsequent operation, however, no further air from the spring chamber would get into the outlet because its overpressure has already been reduced and the sealing lip allows the passage of air only in one direction and thus no re-entry of air into the spring chamber. Likewise, penetration of the product across the sealing lip into the spring chamber is prevented.

Insbesondere kann die Dichtlippe als Topfmanschette ausgebildet sein. Die Topfmanschette wird durch den Produktdruck zusätzlich gegen die Innenseite des Auslaßkanals gedrückt und sorgt so für eine besonders hohe Dichtwirkung.In particular, the sealing lip may be formed as a cup sleeve. The cup seal is additionally pressed by the product pressure against the inside of the outlet channel and thus ensures a particularly high sealing effect.

Das gummielastische Material kann ein Kunststoff sein. Ein derartiges Material ermöglicht eine einfache Herstellung des Verschlußstücks als einstückiges Teil.The rubber-elastic material may be a plastic. Such a material allows easy production of the closure piece as a one-piece part.

Die dargestellte Saug-Druck-Pumpe 1 ist auf dem Rand der Öffnung eines Behältnisses 2 über eine dazwischen angeordnete Dichtringscheibe 3 dicht befestigt. Die Saug-Druck-Pumpe 1 hat ein hohlzylindrisches Gehäuse 4. Das untere Ende des Gehäuses 4 ist durch ein Rückschlagventil mit einer Ventilverschlußkugel 5 absperrbar. Die Ventilverschlußkugel 5 sitzt in ihrer in Fig. 1 dargestellten unteren Lage auf einem Ventilsitz 6 dicht auf.The illustrated suction-pressure pump 1 is tightly mounted on the edge of the opening of a container 2 via a sealing ring disc 3 arranged therebetween. The suction-pressure pump 1 has a hollow cylindrical housing 4. The lower end of the housing 4 can be shut off by a check valve with a valve closure ball 5. The valve closure ball 5 is seated in its illustrated in Fig. 1 lower layer on a valve seat 6 tight.

In dem Gehäuse 4 ist ein hohlzylindrischer Kolben 7, gegen die Innenseite des Gehäuses 4 dichtend, axial verschiebbar gelagert. Die Bohrung 8 des Kolbens 7 setzt sich in einer am Kolben 7 angeformten, hohlen Kolbenstange 9 fort. Die Kolbenstange 9 ist in einer Öffnung 10 einer oberen Verschlußhaube 11 von Gehäuse 4 und Behälter 2 abgedichtet verschiebbar.In the housing 4 is a hollow cylindrical piston 7, sealingly against the inside of the housing 4, axially displaceably mounted. The bore 8 of the piston 7 is continued in a piston 7 integrally formed on the hollow piston rod 9. The piston rod 9 is sealed in an opening 10 of an upper closure cap 11 of the housing 4 and container 2 slidably.

Auf dem freien Ende der aus dem Gehäuse 4 herausragenden Kolbenstange 9 ist ein Betätigungskopf 12 der Saug-Druck-Pumpe 1 dicht und fest aufgesetzt. Den Betätigungskopf 12 durchsetzt ein Auslaßkanal, bestehend aus Auslaßkanalabschnitten 13a-13d, der sich an die Bohrung 8 anschließt. Der Auslaßkanalabschnitt 13b ist als Ringraum ausgebildet, der durch die Innenseite einer Bohrung 14 im Körper des Betätigungskopfes 12 und die Außenseite eines in die Bohrung 14 fest eingesetzten Rohres 15 begrenzt ist. Der Auslaßkanalabschnitt 13c ist eine durch die Wand des Rohres 15 hindurchgehende Bohrung, die in den den Innenraum des Rohres 15 bildenden Auslaßkanalabschnitt 13d mündet. Das Rohr 15 verjüngt sich zu seinem äußeren Ende hin zu einer Ausspritzöffnung 16. In dem Auslaßkanalabschnitt 13d ist ein durch eine schwache Feder 17 belastetes Verschlußstück 18 axial verschiebbar angeordnet. Das Verschlußstück 18 hat einen gegen die Innenseite des Auslaßkanalabschnitts 13d in dem Rohr 15 dichtenden Kolben 19 mit einer Kolbenstange 20, die in der in Fig. 1 dargestellten Schließstellung des Verschlußstücks 18 mit einem Endabschnitt 20a dicht in die Ausspritzöffnung 16 ragt. Der an den Endabschnitt 20a angrenzende Abschnitt 20b der Kolbenstange 20 hat einen größeren Durchmesser als die Austrittsöffnung 16 und liegt in der Schließstellung des Verschlußstücks 18 mit einem schrägen Übergang vom größeren zum kleineren Durchmesser am inneren Rand der Ausspritzöffnung 16 unter der Kraft der Feder 17 an. Der Kolben 19 hat eine umlaufende Dichtlippe 21, die unter ihrer Eigenelastizität an der Innenseite des Rohres 15 bzw. des Auslaßkanalabschnitts 13d dicht anliegt und einen Durchtritt eines Mediums nur in Richtung zur Ausspritzöffnung 16 zuläßt, dagegen zu der die Feder 17 aufweisenden Kammer 22 sperrt. Die Dichtlippe 21 ist durch eine Topfmanschette gebildet. Das Verschlußstück 18 besteht aus gummielastischem Material, insbesondere einem Elastomer-Kunststoff mit einem Übermaß des Endabschnitts 20a der Kolbenstange 20 gegenüber dem Durchmesser der Ausspritzöffnung 16.On the free end of the protruding from the housing 4 piston rod 9, an actuating head 12 of the suction-pressure pump 1 is tightly and firmly placed. The actuating head 12 passes through an outlet channel, consisting of outlet channel sections 13a-13d, which adjoins the bore 8. The outlet passage 13b is formed as an annular space which is bounded by the inside of a bore 14 in the body of the actuating head 12 and the outside of a tube 15 fixedly inserted into the bore 14. The outlet channel section 13c is a hole passing through the wall of the tube 15 and opening into the outlet channel section 13d forming the interior of the tube 15. The tube 15 tapers toward its outer end toward an ejection port 16. In the outlet passage section 13d a loaded by a weak spring 17 closure member 18 disposed axially displaceable. The closure member 18 has a against the inside of the Auslaßkanalabschnitts 13d in the tube 15 sealing piston 19 with a piston rod 20 which projects in the closed position shown in Fig. 1 of the closure member 18 with an end portion 20a in the ejection opening 16. The adjacent to the end portion 20 a portion 20 b of the piston rod 20 has a larger diameter than the outlet opening 16 and is in the closed position of the closure member 18 with an oblique transition from larger to smaller diameter at the inner edge of the ejection opening 16 under the force of the spring 17. The piston 19 has a circumferential sealing lip 21 which rests tightly under its own elasticity on the inside of the tube 15 and the outlet passage 13d and allows passage of a medium only in the direction of the ejection opening 16, however, to the spring 17 having chamber 22 blocks. The sealing lip 21 is formed by a cup seal. The closure member 18 is made of rubber-elastic material, in particular an elastomeric plastic with an excess of the end portion 20 a of the piston rod 20 relative to the diameter of the ejection opening sixteenth

Der Kolben 7 liegt in seiner unbetätigten Lage nach den Fig. 1, 3 und 5 mit einer an seinem freien Ende umlaufenden Dichtlippe 24 dicht an der Innenseite des Gehäuses 4 an. Ein den Kolben 7 oberhalb der Dichtlippe 24 umgebender Bund 25 dient der Führung des Kolbens 7 während seiner Bewegung, läßt jedoch ein Spiel zwischen sich und der Innenseite des Gehäuses 4 frei. Eine Rückstellfeder 26, die unterbrochen dargestellt ist, stützt sich einerseits im Kolben 7 am Boden eines Ringraums 27, der von der äußeren Wand des Kolbens 7 und einem Rohrstutzen 28 begrenzt ist, und andererseits an einer Schulter 29 im Gehäuse 4 ab. Das Gehäuse hat am Ende eines durch das Gehäuse 4 begrenzten Druckraums 30 eine Abstufung 31, unterhalb der der Innendurchmesser des Gehäuses 4 etwas größer als der Außendurchmesser der Dichtlippe 24 des Kolbens 7 ist. In einem Anschlußstutzen 32 am freien unteren Ende des Gehäuses 4 ist ein bis nahe an den Boden des Behältnisses 2 ragendes Tauchrohr 34 befestigt. Oberhalb der oberen Endlage des Kolbens 7 gemäß Fig. 1 ist das Gehäuse 4 durch seitliche Schlitze 35 mit dem Innenraum des Behältnisses 2 oberhalb des maximalen Produkt-Füllstandes verbunden.The piston 7 is in its unactuated position according to FIGS. 1, 3 and 5 with a circumferential at its free end sealing lip 24 close to the inside of the housing 4 at. A collar 25 surrounding the piston 7 above the sealing lip 24 serves to guide the piston 7 during its movement, but leaves a clearance between it and the inside of the housing 4 free. A return spring 26, which is shown interrupted supports on the one hand in the piston 7 at the bottom of an annular space 27 which is bounded by the outer wall of the piston 7 and a pipe socket 28, and on the other hand on a shoulder 29 in the housing 4 from. The housing has at the end of a limited by the housing 4 pressure chamber 30 a gradation 31, below which the inner diameter of the housing 4 is slightly larger than the outer diameter of the sealing lip 24 of the piston 7. In a connection piece 32 at the free lower end of the housing 4 a projecting to near the bottom of the container 2 immersion tube 34 is attached. Above the upper end position of the piston 7 according to FIG. 1, the housing 4 is connected by lateral slots 35 with the interior of the container 2 above the maximum product level.

Bei der erstmaligen Betätigung des Betätigungskopfes 12 durch manuelle Ausübung eines Drucks auf seine Oberseite bewegt sich der Kolben 7 gegen die Kraft der Rückstellfeder 26 in dem Raum 30 gemäß Fig. 2 in Richtung auf das Rückschlagventil 5, 6. Durch den dabei im Raum 30, in der Bohrung 8 und im Auslaßkanal 13a-13d entstehenden Druck wird einerseits das Rückschlagventil 5, 6 geschlossen gehalten und andererseits die Dichtlippe 21 des Verschlußstücks 18 an die Innenseite des Rohres 15 bzw. des durch sie begrenzten Auslaßkanalabschnitts 13d gedrückt. Infolgedessen wird der Kolben 19 gegen die Kraft der Feder 17 verschoben und der Endabschnitt 20a der Kolbenstange 20 aus der Ausspritzöffnung 16 herausgezogen. Dabei kann die im Raum 30, in der Bohrung 8, im Auslaßkanal 13a-13d und in der Federkammer 22 enthaltene Luft teilweise durch die Ausspritzöffnung 16 austreten. Nach Wegnahme des manuellen Drucks vom Betätigungskopf 12 drückt die Rückstellfeder 26 den Kolben 7 und die Feder 17 den Kolben 19 in die in Fig. 3 dargestellte Lage zurück. Durch den dabei im Raum 30, in der Bohrung 8 und im Auslaßkanal 13a-13d entstehenden Unterdruck wird die Ventilverschlußkugel 5 bis gegen über ihr im Gehäuse 4 ausgebildete Rippen 37 von ihrem Sitz 6 abgehoben. Gleichzeitig wird durch den Unterdruck aus dem Behältnis 2 ein Teil des im Behältnis 2 enthaltenen Produkts 38 über das Tauchrohr 34 und das geöffnete Rückschlagventil 5, 6 bis in den Raum 30 gesaugt, wie es in Fig. 3 dargestellt ist. Das Produkt 38 ist vorzugsweise pastenartig, kann aber auch eine Flüssigkeit sein.During the first actuation of the actuating head 12 by manually exerting pressure on its upper side, the piston 7 moves against the force of the return spring 26 in the space 30 according to FIG. 2 in the direction of the check valve 5, 6. in the bore 8 and in the outlet channel 13a-13d resulting pressure on the one hand, the check valve 5, 6 is kept closed and pressed the other hand, the sealing lip 21 of the closure member 18 to the inside of the tube 15 and the limited by them outlet channel section 13d. As a result, the piston 19 is displaced against the force of the spring 17 and the end portion 20 a of the piston rod 20 is pulled out of the ejection opening 16. In this case, the air contained in the space 30, in the bore 8, in the outlet channel 13a-13d and in the spring chamber 22 partially escape through the ejection opening 16. After removal of the manual pressure from the actuator head 12, the return spring 26 presses the piston 7 and the spring 17, the piston 19 in the position shown in Fig. 3 back. By doing in the space 30, in the bore 8 and the outlet 13a-13d resulting negative pressure valve closure ball 5 is lifted up against her in the housing 4 formed ribs 37 from its seat 6. At the same time, a portion of the product 38 contained in the container 2 is sucked through the dip tube 34 and the open check valve 5, 6 into the space 30 by the negative pressure from the container 2, as shown in Fig. 3. The product 38 is preferably pasty, but may also be a liquid.

Durch erneutes Niederdrücken des Kolbens 7 mittels des Betätigungskopfes 12 wird das Rückschlagventil 5, 6 wieder geschlossen und der Kolben 19 wieder gegen die Kraft der Feder 17 in die in Fig. 2 dargestellte Lage gedrückt. Gleichzeitig wird das Produkt aus dem Raum 30 über die Bohrung 8, den Auslaßkanal 13a-13d und die wieder geöffnete Ausspritzöffnung 16 ausgestoßen, wie es in Fig. 4 dargestellt ist. Dabei kann der Kolben 7 mit seiner Dichtlippe 24 bis unter die Abstufung 31 gedrückt werden. Sobald die Dichtlippe 24 dabei die Abstufung 31 überquert hat, wird der Druck im Raum 30 an der Dichtlippe 24 und dem Bund 25 des Kolbens 7 vorbei durch die Schlitze 35 in den Raum des Behältnisses 2 oberhalb des Produkt-Füllstandes abgebaut, so daß kein weiteres Produkt 38 mehr ausgestoßen wird. Dadurch wird die bei jeder Betätigung ausgegebene Produktmenge genau dosiert.By again depressing the piston 7 by means of the actuating head 12, the check valve 5, 6 is closed again and the piston 19 again pressed against the force of the spring 17 in the position shown in Fig. 2. At the same time, the product is ejected from the space 30 via the bore 8, the outlet channel 13a-13d and the re-opened ejection opening 16, as shown in Fig. 4. In this case, the piston 7 can be pressed with its sealing lip 24 to below the gradation 31. As soon as the sealing lip 24 has crossed the gradation 31, the pressure in the space 30 at the sealing lip 24 and the collar 25 of the piston 7 is degraded by the slots 35 in the space of the container 2 above the product level, so that no further Product 38 is ejected more. This will accurately dose the amount of product dispensed each time it is pressed.

Während der sich nach Wegnahme des manuellen Drucks auf den Betätigungskopf 12 anschließenden Rückbewegung des Kolbens 7 saugt der Kolben 7 erneut einen Teil des Produkts 38 aus dem Behältnis 2 in den Raum 30, wobei der Kolben 19 wieder die Ausspritzöffnung 16 unter dem Druck der Feder 17 schließt, wie es in Fig. 5 dargestellt ist.During the subsequent movement of the manual pressure on the actuating head 12 subsequent return movement of Piston 7, the piston 7 sucks again a portion of the product 38 from the container 2 in the space 30, wherein the piston 19 again closes the ejection opening 16 under the pressure of the spring 17, as shown in Fig. 5.

Wenn der Kolben 7 aus der Lage nach Fig. 5 erneut in die Lage nach Fig. 4 niedergedrückt wird, wird sofort wieder eine genau dosierte Produktmenge ausgegeben. Das gleiche geschieht bei jeder weiteren Betätigung bis zur völligen Entleerung des Behältnisses 2.When the piston 7 is pressed again from the position shown in FIG. 5 in the position shown in FIG. 4, a precisely metered amount of product is immediately issued again. The same happens at each further operation until complete emptying of the container. 2

Wie die Fig. 1, 3 und 5 zeigen, ist der Auslaßkanal 13a-13d in der Schließstellung des Verschlußstücks 18 nach außen hin völlig durch das Verschlußstück 18 abgesperrt. Ein im Auslaßkanal verbliebener Produktrest kann daher nicht mit schädlichen Keimen, Bakterien, Viren usw. sowie mit schädlichen Materien, Gasen usw. in Berührung kommen. Die Offenstellung des Verschlußstücks 18 nach den Fig. 2 und 4 dauert dagegen nur kurzzeitig an. Ein im Auslaßkanal 13a-13d verbliebener Produktrest würde dagegen bei der Produktausgabe weitgehend ausgestoßen und könnte nicht kontaminiert werden, da die Offenstellung des Verschlußstücks 18 nur kurzzeitig andauert.As shown in FIGS. 1, 3 and 5, the outlet channel 13a-13d is shut off in the closed position of the closure member 18 to the outside completely by the closure member 18. A product residue remaining in the outlet channel therefore can not come into contact with harmful germs, bacteria, viruses, etc. as well as with harmful materials, gases, etc. The open position of the closure member 18 of FIGS. 2 and 4, however, takes only a short time. By contrast, a product residue remaining in the outlet channel 13a-13d would be largely expelled during product delivery and could not be contaminated since the open position of the closure piece 18 lasts only for a short time.

Das Verschlußstück 18 wirkt nicht nur als solches, sondern auch als Druckkolben, der das nach der Betätigung des Betätigungskopfes 12 im Abschnitt 13d des Auslaßkanals verbliebene Produkt unter der Kraft der Feder 17 durch die Ausspritzöffnung 16 ausspritzt und dabei gleichzeitig die Ausspritzöffnung 16 absperrt. Der den größeren Durchmesser aufweisende Abschnitt 20b der Kolbenstange 20 legt sich dabei während der Schließbewegung des Verschlußstücks 18 unter der Kraft der Feder 17 mit seiner vom größeren zum kleineren Durchmesser übergehenden Schulterfläche zusätzlich abdichtend am inneren Rand der Ausspritzöffnung 16 an. Gleichzeitig wird dadurch die Schließbewegung des Verschlußstücks 18 begrenzt.The closure member 18 acts not only as such, but also as a pressure piston which ejects the remaining after actuation of the actuator head 12 in the portion 13d of the outlet channel product under the force of the spring 17 through the ejection opening 16 and at the same time the ejection opening 16 shuts off. The larger diameter portion 20b of the piston rod 20 sets during the closing movement of the closure member 18 under the force of the spring 17 with its larger diameter from the smaller diameter shoulder surface sealingly on the inner edge of the ejection opening 16 at. At the same time thereby the closing movement of the closure member 18 is limited.

Die Dichtlippe 21 ermöglicht einerseits den Durchtritt von Luft aus der Federkammer 22 in den Auslaßkanal bei der erstmaligen Betätigung des Betätigungskopfes 12 und einer dadurch bedingten Verschiebung des Kolbens 19 gegen die Kraft der Feder 17. Daher ist im wesentlichen nur die Kraft der Feder 17 durch den Produktdruck während der Produktausgabe zu überwinden. Die dabei aus der Federkammer 22 in den Auslaßkanal eingedrungene Luft würde sich bei der erstmaligen Betätigung dann zwar teilweise mit der ausgegebenen und bei der nächsten Betätigung auszugebenden Produktmenge vermischen. Bei der zweiten und jeder folgenden Betätigung würde jedoch keine weitere Luft aus der Federkammer 22 in den Auslaßkanal gelangen, weil ihr Überdruck bereits abgebaut ist und die Dichtlippe 21 den Durchtritt der Luft nur in der einen Richtung und damit kein erneutes Eindringen von Luft in die Federkammer 22 zuläßt. Desgleichen wird auch ein Eindringen des Produkts über die Dichtlippe 21 hinweg in die Federkammer 22 verhindert. Da die Dichtlippe als Topfmanschette ausgebildet ist, wird sie durch den Produktdruck zusätzlich gegen die Innenseite des Rohres 15 bzw. des Abschnitts 13d des Auslaßkanals gedrückt. Sie sorgt daher für eine besonders hohe Dichtwirkung. Aufgrund der Ausbildung des Verschlußstücks 18 aus gummielastischem Material und mit einem Übermaß seines Endabschnitts 20a gegenüber dem Innendurchmesser der Ausspritzöffnung 16 legt sich der Endabschnitt 20a in der Schließstellung des Verschlußstücks 18 besonders fest in der Ausspritzöffnung 16 an. Dies ergibt eine besonders hohe Dichtwirkung des Endabschnitts 20a in der Ausspritzöffnung 16. Eine Ausbildung des gummielastischen Materials des Verschlußstücks 18 aus Kunststoff ermöglicht darüber hinaus eine einfache Herstellung des Verschlußstücks 18 als einstückiges Teil.The sealing lip 21 allows on the one hand the passage of air from the spring chamber 22 in the outlet channel at the first actuation of the actuating head 12 and consequent displacement of the piston 19 against the force of the spring 17. Therefore, essentially only the force of the spring 17 by the Overcome product pressure during product dispensing. The case thereby penetrated from the spring chamber 22 in the exhaust passage air would then be partially mixed with the output and to be issued at the next operation amount of product at the first actuation. In the second and each subsequent operation, however, no further air from the spring chamber 22 would get into the outlet, because its pressure is already reduced and the sealing lip 21 the passage of air only in one direction and thus no re-entry of air into the spring chamber 22 allows. Likewise, penetration of the product beyond the sealing lip 21 into the spring chamber 22 is prevented. Since the sealing lip is formed as a cup seal, it is additionally pressed by the product pressure against the inside of the tube 15 and the portion 13 d of the outlet channel. It therefore ensures a particularly high sealing effect. Due to the formation of the closure piece 18 made of rubber-elastic material and with an excess of its end portion 20a with respect to the inner diameter of the ejection opening 16, the end portion 20a sets particularly firmly in the ejection opening 16 in the closed position of the closure member 18. This results in a particularly high sealing effect of the end portion 20a in the ejection opening 16. A design of the rubber-elastic material of the closure piece 18 made of plastic also allows easy production of the closure member 18 as an integral part.
