Description

Die Erfindung betrifft eine als Kippverschluß ausgebildete Verschlußvorrichtung für Behälter mit fließfähigen Medien, insbesondere für Reinigungsmittel, Kosmetika od. dgl., bestehend aus einem mit einer Behälteröffnung mediendicht befestigbarem Gehäuse mit einem Austrittsstutzen, der mit einer das Medium freigebenden Austrittsöffnung verbunden ist, einem mediendurchströmbaren Verschlußrohr, mittels dessen der Austrittsstutzen mediendicht verschließbar und freigebbar ist, sowie einem als Kipphebel ausgebildeten Betätigungselement an dem der Austrittskanal für das Medium vorgesehen ist, mittels dessen das Verschlußrohr in seine Sollposition überführbar ist.The invention relates to a trained as a tilt lock Closing device for containers with flowable media, in particular for cleaning agents, cosmetics or the like from a media-fastened with a container opening Housing with an outlet nozzle that connected to an outlet opening releasing the medium is, a sealing tube through which media can flow of which the outlet connection can be closed in a media-tight manner can be released, as well as a rocker arm Actuating element on which the outlet channel for the medium is provided, by means of which the sealing tube in its target position can be transferred.

Aus der EP 0 111 811 A1 ist eine Verschlußvorrichtung bekannt, bei der das Betätigungselement als Kippdeckel ausgeführt ist. An der Unterseite des Kippdeckels ist ein als Dichtring ausgebildetes Verschlußelement angeordnet, das abdichtend in die Austrittsöffnung des Austrittsstutzens eingreift. In radialem Abstand zu diesem Dichtring ist an der Unterseite des Kippdeckels eine Dichtkappe angeordnet, die in der Verschlußstellung sowie in der Öffnungsstellung den Austrittsstutzen außenseitig dichtend umschließt. Hierdurch ist gewährleistet, daß das in dem Behälter bevorratete Medium beim Passieren der Verschlußvorrichtung direkt der Austrittsöffnung zugeführt wird und nicht in Hohlräume der Verschlußvorrichtung eindringt, die dem Verschlußelement benachbart sind, wodurch unnötige Verluste des bevorrateten Mediums entstehen würden sowie die Handhabbarkeit der Verschlußvorrichtung beeinträchtigt werden könnte.A closure device is known from EP 0 111 811 A1 known in which the actuating element as a tilt lid is executed. At the bottom of the tilt lid is a closure element designed as a sealing ring is arranged, the sealing in the outlet opening of the outlet nozzle intervenes. A radial distance from this sealing ring is on the Bottom of the tilting lid a sealing cap arranged in the outlet position in the closed position and in the open position seals on the outside. This is ensures that the medium stored in the container at Pass the closure device directly to the outlet opening is supplied and not in cavities of the closure device penetrates, which are adjacent to the closure element, whereby unnecessary losses of the stored medium would arise and impaired the handling of the closure device could be.

Es ist oftmals erforderlich, derartige Verschlußvorrichtungen bei fließfähigen Medien mit stark unterschiedlicher Viskosität einzusetzen. Des weiteren sind die Medien je nach Anwendungszweck in stark unterschiedlichen Dosierungen zu verwenden. Es sind daher Verschlußvorrichtungen erwünscht, die wahlweise mindestens zwei unterschiedliche Öffnungsquerschnitte freigeben, so daß der Öffnungsquerschnitt dem jeweils vorliegenden Medium bzw. dessen Dosierung anpaßbar ist. Dabei sollte der freigebbare Öffnungsquerschnitt über einen möglichst großen Bereich variierbar sein, so daß die Verschlußvorrichtung möglichst universell einsetzbar ist. Bei der in der EP 0 411 311 A1 beschriebenen Verschlußvorrichtung erweist sich hierbei als nachteilig, daß das Verschlußelement nur in eine geöffnete und in eine geschlossene Stellung überführbar ist, so daß nicht je nach Viskosität der Medien wahlweise unterschiedliche Öffnungsquerschnitte freigebbar sind. Des weiteren ist der Öffnungsquerschnitt aufgrund des beschränkten Verschwenkbereiches des Verschlußelementes auf eine vergleichsweise geringe Größe beschränkt, da anderenfalls eine dichtende Anlage der Dichtkappe an dem Austrittsstutzen nicht gewährleistbar ist.Such closures are often required for flowable media with very different viscosities to use. Furthermore, the media are depending on the application to be used in very different dosages. It closure devices are therefore desired, which are optional release at least two different opening cross-sections, so that the opening cross-section to the present Medium or its dosage is adjustable. The openable opening cross-section over the largest possible Range can be varied so that the closure device as possible is universally applicable. In the case of EP 0 411 311 A1 described locking device proves to be disadvantageous that the closure element only in an open and can be moved into a closed position so that not different depending on the viscosity of the media Opening cross sections can be released. Furthermore is the Opening cross-section due to the limited swivel range of the closure element to a comparatively low Size limited, otherwise a sealing system of the Sealing cap on the outlet nozzle is not guaranteed.

Bei der aus der EP 0 111 813 bekannten gattungsgemäßen Vorrichtung ist das Verschlußrohr auf dem Austrittsstutzen so aufsetzbar, daß dieses im verschlossenen Zustand den Austrittsstutzen in sich aufnimmt. Das Verschlußrohr und der Austrittsstutzen verlaufen in Einbaulage kollinear zueinander. Das an dem Deckel angeformte Verschlußrohr wird beim Öffnen von dem Austrittsstutzen durch Kippen des Kipphebels beabstandet. Das Verschlußrohr bleibt mit dem Austrittsstutzen im geöffneten Zustand an einer Anlagekante in Verbindung. Bei einer nur teilweisen Öffnung der Austrittsöffnung erhöht sich durch den Rückstau der interne Druck innerhalb der Verschlußkappe. Dieser Rückstau tritt insbesondere an der Anlagekante zwischen Verschlußrohr und Austrittsstutzen auf, so daß es hier vornehmlich zu Undichtigkeiten kommt.In the generic device known from EP 0 111 813, this is Locking tube can be placed on the outlet connection so that this in the closed state the outlet nozzle in itself records. The sealing tube and the outlet pipe run in the installation position collinear to each other. The molded on the lid The closure tube is opened by the outlet nozzle spaced by tilting the rocker arm. The sealing tube remains in one position with the outlet nozzle in the open state Contact edge in connection. With only a partial opening the back opening increases the internal back pressure Pressure inside the cap. This backlog occurs especially on the contact edge between the sealing tube and Outlet connection on, so that there are mainly leaks is coming.

Der Erfindung liegt das technische Problem zugrunde, eine gattungsgemäße Verschlußvorrichtung derart weiterzuentwickeln, daß Undichtigkeiten innerhalb der Verschlußvorrichtung vermieden werden, die insbesondere im teilweise geöffneten Zustand durch den Rückstau des Mediums entstehen. The invention is based on the technical problem to further develop the generic closure device in such a way that leaks are avoided within the closure device be, especially in the partially open state caused by the back pressure of the medium.

Zur Lösung dieses technischen Problems wird erfindungsgemäß vorgeschlagen, daß das Verschlußrohr beim Öffnen über seinen gesamten Umfang abdichtend in der Führungshülse längsverschieblich geführt ist, daß ein Endbereich desselben eine mediendicht von einem Dichtsitz aufnehmbare Eintrittsöffnung aufweist und ein anderer Endbereich, mit der das Medium freigebenden Austrittsöffnung in Verbindung steht, wobei das Verschlußrohr und der Dichtsitz relativ zueinander beabstandbar sind, so daß das Verschlußrohr bei der Beabstandung über seinen gesamten Verfahrweg mediendicht in der Führungshülse geführt ist, daß in Abhängigkeit von der Beabstandung die Eintrittsöffnung des Verschlußrohrs in mindestens zwei unterschiedliche Öffnungsquerschnitte freigebbar ist, und daß das flexible Verschlußrohr radial nach außen versetzt ist zum Umfang des Austrittsstutzens.To solve this technical problem, the invention suggested that the closure tube when opening over sealingly displaceable along its entire circumference in the guide sleeve is that an end portion of the same one Media-tight entry opening that can be accommodated by a sealing seat has and another end region with which the medium releasing Exit opening is connected, the closure tube and the sealing seat can be spaced apart from one another are so that the closure tube at the spacing above its The entire travel path is media-tight in the guide sleeve is that depending on the spacing Entry opening of the closure tube in at least two different Opening cross sections can be released, and that the flexible Closure tube is offset radially outwards to the circumference of the outlet nozzle.

Durch das Ausmaß der Beabstandung des mediendurchströmbaren Verschlußelementes relativ zu dem Dichtsitz sind unterschiedliche Öffnungsquerschnitte der Eintrittsöffnung freigebbar. Da das bei der Beabstandung verfahrene Verschlußrohr über seinen gesamten Verfahrweg in dem Führungsrohr geführt wird, kann die Beabstandung so bemessen werden, daß in der Endstellung des Verfahrweges der von der Eintrittsöffnung freigegebene Querschnitt dem Querschnitt des mediendurchströmbaren Verschlußelementes entspricht. Damit ist ein maximaler Öffnungsquerschnitt geschaffen, so daß auch hochviskose Medien die Verschlußvorrichtung einfach passieren können. Das Verschlußelement kann dabei kontinuierlich oder stufenweise auf verschiedene Sollpositionen eingestellt werden, solange gewährleistet ist, daß bei der Höhenverstellung des Bauteils eine mediendichte Führung gewährleistet ist. Der Verfahrweg erfolgt entlang eines Kreisbogens. Der Klarstellung halber sei ausgeführt, daß die Beabstandung von Verschlußelement und Dichtsitz das Verschlußelement oder der Dichtsitz oder beide mittels des Betätigungselementes verfahren werden können.Due to the extent of the spacing of the media Closure element relative to the sealing seat are different Opening cross-sections of the entry opening can be released. There the sealing tube moved during the spacing over its the entire travel path in the guide tube, the Distance should be such that in the end position of the Travel the cross section released by the inlet opening the cross section of the closure element through which media can flow corresponds. This is a maximum opening cross-section created so that even highly viscous media Locking device can easily pass. The closure element can vary continuously or in stages Target positions can be set as long as guaranteed is that in the height adjustment of the component media-tight leadership is guaranteed. The travel path takes place along an arc. For the sake of clarification, that the spacing of the closure element and sealing seat the closure element or the sealing seat or both by means of the Actuator can be moved.

Vorteilhafterweise weist der Austrittsstutzen eine seitliche Öffnung auf, durch die das Verschlußelement im Bereich des Dichtsitzes von dem austretenden Medium seitlich anströmbar ist. Hierdurch ist eine Ausführungsform mit besonders geringer Bauhöhe geschaffen. Dabei kann das Verschlußelement beispielsweise eine seitlich angeordnete Eintrittsöffnung aufweisen, die zu der seitlichen Öffnung des Austrittsstutzens fluchtend positionierbar ist.The outlet connection advantageously has a lateral one Opening through which the closure element in the area of Sealing seat from the emerging medium can flow to the side is. This makes an embodiment with a particularly low Height created. The closure element can, for example have an inlet opening on the side, aligned with the side opening of the outlet port is positionable.

Das Verschlußelement ist als vertikal angeordnetes, höhenverstellbares Rohr ausgeführt. Die mediendichte Führung ist als ein das Rohr voll umfänglich umschließender Zylinder ausgeführt oder erstreckt sich nur über einen Teilbereich des Umfangs.The closure element is a vertically arranged, height-adjustable Tube executed. The media-tight leadership is as a cylinder completely surrounding the tube or extends only over part of the circumference.

Besonders vorteilhaft ist es, wenn das rohrförmige Verschlußelement an seiner unteren Stirnseite offen ausgeführt ist und mit dieser abdichtend an den Dichtsitz anlegbar ist. Hierdurch kann bei entsprechender Beabstandung, beispielsweise durch vertikalen Hub, der gesamte Innenquerschnitt des Rohres freigegeben werden. Der Dichtsitz kann dabei ortsfest an dem Gehäuse angeordnet sein, beispielsweise, indem er einstückig an diesem angeformt ist.It when the tubular closure element is particularly advantageous is open at its lower end and can be applied sealingly to the sealing seat. Hereby can with appropriate spacing, for example by vertical stroke, the entire inner cross-section of the pipe is released become. The sealing seat can be stationary on the housing be arranged, for example, by being in one piece this is molded.

Das Rohr ist an seiner oberen Stirnseite mit einer Öffnung versehen, welche über einen Austrittskanal mit der Austrittsöffnung der Verschlußvorrichtung in Verbindung steht. Der Austrittskanal kann sich - ausgehend von der Stirnseite - auch über einen Teilbereich der seitlichen Rohrwandung erstrecken.The tube has an opening on its upper face provided, which via an outlet channel with the outlet opening the closure device is in communication. The Exit channel can - starting from the front - too extend over a portion of the side tube wall.

Eine konstruktiv besonders einfache Ausführungsform liegt vor, wenn das Verschlußelement mit dem der Austrittsöffnung zugewandten Ende einstückig an dem Betätigungselement angeformt ist.A particularly simple design is available, if the closure element with that facing the outlet opening Formed in one piece on the actuating element is.

Des weiteren ist es vorteilhaft, wenn der Austrittskanal in dem Betätigungselement angeordnet ist und seitlich aus diesem austritt, wobei das Betätigungselement in der Verschlußstellung des Verschlußelementes im Bereich des Austrittskanals abdichtend an der Innenwand des Gehäuses anliegt und in der ersten der Öffnungspositionen die Austrittsöffnung vollständig freigibt. Hierdurch liegt eine Verschlußvorrichtung mit zwei Dichtungsbereichen vor, die einen besonders sicheren Einschluß des in dem Behälter bevorrateten Mediums gewährleistet. Des weiteren ist in jeder Öffnungsposition der Austrittskanal vollständig freigelegt und durch das austretende Medium vollständig durchspülbar, so daß sich keine Verkrustungen des Mediums im Austrittskanal festsetzen können.Furthermore, it is advantageous if the outlet channel is in the actuating element is arranged and laterally from this emerges, the actuating element in the closed position of the closure element in the area of the outlet channel seals against the inner wall of the housing and in the first of the opening positions the outlet opening completely releases. As a result, there is a closure device with two Sealing areas before that a particularly safe enclosure of the medium stored in the container. Of the outlet channel is in each open position completely exposed and completely through the escaping medium flushable, so that no incrustations of the Can fix medium in the outlet channel.

Die das Verschlußelement mediendicht umgebende Führung ist vorzugsweise kreisbogenartig geformt, so daß eine Rohr-in-Rohr-Führung gegeben ist.The guide surrounding the closure element is media-tight preferably shaped like a circular arc, so that a tube-in-tube guide given is.

Es ist besonders vorteilhaft, wenn das Verschlußrohr exzentrisch zur Schwenkachse des Kipphebels mit diesem verbunden ist. Ist beispielsweise eine zylindrische Führungshülse vorgesehen, so erfolgt unter Verschwenkung des Kipphebels ein Hub des in der Führungshülse angeordneten flexiblen Rohres und der aus der zylindrischen Führungshülse vorstehende Bereich des flexiblen Rohres wird bogenförmig deformiert. Hierdurch ist die vergleichsweise aufwendige Ausbildung von bogenförmig geformten, relativ zueinander bewegten Bauteilen, die abdichtend aneinander anliegen, entbehrlich und eine besonders einfache, sehr gut abdichtende Rohr-in-Rohr-Führung geschaffen.It is particularly advantageous if the sealing tube is eccentric connected to the pivot axis of the rocker arm is. If, for example, a cylindrical guide sleeve is provided, so there is a stroke by pivoting the rocker arm of the flexible tube arranged in the guide sleeve and the protruding area of the cylindrical guide sleeve flexible pipe is deformed into an arc. This is the comparatively complex formation of arches molded, relatively moving components that seal close to each other, dispensable and a particularly simple, very good sealing pipe-in-pipe guide created.

Das flexible Rohr wird bei Betätigung eines Kipphebels bogenförmig deformiert, so daß aufgrund der elastischen Deformation des Verschlußelementes auf den in einer Öffnungsposition befindlichen Kipphebel elastische Rückstellkräfte wirken. Es ist dann besonders vorteilhaft, eine Rastsperre mit verschiedenen Rastpositionen vorzusehen, die an den Kipphebel angreift und diesen in seinen verschiedenen Öffnungspositionen rastend arretiert. Eine derartige Rastsperre ist jedoch für eine einfache Einstellung der Dosierung vorteilhaft, wenn das Betätigungselement als Schieber ausgeführt ist. The flexible tube becomes curved when a rocker arm is actuated deformed so that due to the elastic deformation of the closure element on the one in an open position Rocker arms have elastic restoring forces. It is then particularly advantageous, a detent with different To provide latching positions that engage the rocker arm and locking this in its various opening positions locked. Such a locking device is, however, simple Setting the dosage is advantageous when the actuator is designed as a slide.

Die in den Figuren 1 bis 5 dargestellte erfindungsgemäße Verschlußvorrichtung ist als Kippverschluß ausgeführt. Die Verschlußvorrichtung 1 weist ein topfförmiges Gehäuse 2 auf, das koaxial zu dem Austrittsstutzen 3 des Behälters angeordnet und mittels des Gewindestutzens 4 mit diesem verschraubt ist. Das Gehäuse 2 weist einen zylindrischen Austrittsstutzen 5 auf, der koaxial in dem Gehäuse 2 angeordnet und mit einer seitlichen Öffnung 6 versehen ist. Konzentrisch zwischen dem Austrittsstutzen 5 und dem Gewindestutzen 4 ist eine Dichtlippe 7 angeordnet, die abdichtend an dem Austrittsstutzen 3 des Behälters anliegt. Die seitliche Öffnung 6 des Austrittsstutzens 5 ist durch den als Verschlußelement wirkenden, vertikal angeordneten Rohrabschnitt 8 mediendicht verschließbar und in verschiedenen Öffnungsstellungen freigebbar. Der zylindrische Rohrabschnitt 8 ist in seinem mittleren Bereich über seinen gesamten Umfang abdichtend in einer Führungshülse 9 längsverschiebbar geführt und an seinem oberen Ende einteilig an dem um die horizontal angeordnete Mittelachse des Gehäuses 2 schwenkbar gelagerten Kipphebel 10 angeformt. Das untere, stirnseitig offene Ende des Verschlußrohres 8 kann mediendicht in einem Dichtsitz 11 angeordnet werden, dessen mittlerer Bereich von dem Gewindestutzen 4 unterstützt wird und der einteilig an dem Gehäuse 2 angeformt ist. Hierdurch ist eine besonders stabile als auch raumsparende Anordnung des Dichtsitzes 11 gegeben. Das obere Ende des Verschlußrohres 8 geht in einen rechtwinklig zu diesem abgewinkelten Austrittskanal 12 über, der in dem Kipphebel 10 angeordnet und mit diesem verschwenkbar ist. Dadurch wird bei seitlich an dem Stutzen 5 angeordneter Öffnung 6 das austretende Medium zweimal um jeweils 90° umgelenkt, wodurch eine platzsparende Anordnung der Abdichtbereiche des Dichtsitzes 11 und der Austrittsöffnung 13 gegeben ist. Der Austrittskanal weist dabei einen geringeren Querschnitt als das Verschlußrohr auf, so daß eine strömungstechnisch günstige Ausführungsform gegeben ist. Die das Medium freigebende Austrittsöffnung 13 ist dabei in der in Fig. 1 gezeigten Verschlußstellung der Verschlußvorrichtung hinter einem Teilbereich des Gehäuses 2 angeordnet, wobei das austrittsseitige Ende des Austrittskanals 12 dichtend an der Innenwand des Teilbereichs des Gehäuses 2 anliegt. Des weiteren liegt das untere, stirnseitig offene Ende des Rohres 8 in der in Fig. 1 gezeigten Stellung des Kipphebels 10 dichtend an dem Dichtsitz 11 an. Hierdurch ist eine zweifache Abdichtung der Verschlußvorrichtung gegeben, so daß eine sichere Bevorratung des Mediums in dem Behälter gewährleistet ist.The closure device according to the invention shown in Figures 1 to 5 is designed as a tilt lock. The locking device 1 has a cup-shaped housing 2, the arranged coaxially to the outlet nozzle 3 of the container and is screwed to this by means of the threaded connector 4. The Housing 2 has a cylindrical outlet connection 5, which is arranged coaxially in the housing 2 and with a side Opening 6 is provided. Concentric between the outlet nozzle 5 and the threaded connector 4 is a sealing lip 7 arranged, the sealing on the outlet nozzle 3 of the Of the container. The lateral opening 6 of the outlet nozzle 5 is vertical by acting as a closure element arranged pipe section 8 media-tight closable and in different opening positions can be released. The cylindrical Pipe section 8 is in its central area above its sealing the entire circumference in a guide sleeve 9 longitudinally led and at its upper end in one piece on the about the horizontally arranged central axis of the housing 2 pivoted rocker arm 10 formed. The lower, the open end of the closure tube 8 can be media-tight be arranged in a sealing seat 11, the middle Area is supported by the threaded connector 4 and the is integrally formed on the housing 2. This is one particularly stable and space-saving arrangement of the sealing seat 11 given. The upper end of the sealing tube 8 goes into a right-angled outlet duct 12 over that arranged in the rocker arm 10 and with this is pivotable. Thereby, at the side of the nozzle 5 arranged opening 6, the emerging medium twice around each Deflected 90 °, which creates a space-saving arrangement of the Sealing areas of the sealing seat 11 and the outlet opening 13 given is. The outlet channel has a smaller one Cross section than the closure tube, so that a fluid favorable embodiment is given. The the medium releasing outlet opening 13 is in FIG. 1 shown locking position of the locking device behind a partial area of the housing 2, the outlet side End of the outlet channel 12 sealing against the Inner wall of the portion of the housing 2 abuts. Furthermore is the lower, open end of the tube 8 in the position of the rocker arm 10 shown in Fig. 1 sealing the sealing seat 11. This creates a double seal given the closure device, so that a secure stockpiling of the medium in the container is guaranteed.

Wird die Verschlußvorrichtung unter Betätigung des Kipphebels 10 aus der in Fig. 1 gezeigten Verschlußstellung in eine erste Öffnungsstellung überführt, wie sie beispielhaft in Fig. 2 veranschaulicht ist, so wird das untere stirnseitige Ende des rohrförmigen Verschlußelementes 8 von dem Dichtsitz 11 beabstandet sowie der Austrittskanal 12 mit seinem der Innenwand des Gehäuses 2 zugewandtem Ende nach oben verschwenkt und so die endseitig an dem Austrittskanal 12 angeordnete Austrittsöffnung 13 vollständig oberhalb des Gehäuserandes angeordnet. Bei dieser Verschwenkung wird der oberhalb der Führungshülse 9 angeordnete Bereich des elastischen Verschlußelementes 8 bogenförmig deformiert. Hierdurch kann die Schwenkbewegung des Kipphebels in eine Hubbewegung des Verschlußrohres 8 überführt werden, wobei gleichzeitig das Rohr 8 sowie die dieses dichtend umgebende Führungshülse 9 als zylindrische Bauteile ausführbar sind. Die Beabstandung des unteren Endes des Verschlußelementes 8 von dem Dichtsitz 11 hängt dabei von dem Verschwenkwinkel des Kipphebels 10 sowie von dem Abstand des Verschlußelementes 8 von der Schwenkachse des Kipphebels 10 ab. Da die Verschwenkbewegung des Kipphebels in einen vertikalen Hub des Verschlußelementes 8 überführt wird, kann der Dichtsitz 10 planar ausgeführt werden, während der die Austrittsöffnung 13 abdichtende Bereich der Innenwandung des Gehäuses 2 sowie der dichtend an diesem anliegende Bereich des Austrittskanals 12 in Form von Kugelsphären geformt sind. Aufgrund der planaren Ausführung des Dichtsitzes 11 ist dieser besonders maßgenau herstellbar.The locking device is actuated by the rocker arm 10 from the closed position shown in Fig. 1 in a first Open position, as exemplified in Fig. 2nd is illustrated, so the lower end of the tubular closure element 8 spaced from the sealing seat 11 and the outlet channel 12 with its the inner wall of the housing 2 facing end pivoted up and so the outlet opening arranged at the end on the outlet channel 12 13 arranged completely above the edge of the housing. During this swiveling, it is above the guide sleeve 9 arranged area of the elastic closure element 8 deformed in an arc. This allows the pivoting movement of the Rocker arm converted into a lifting movement of the closure tube 8 be, at the same time the tube 8 and this sealing surrounding guide sleeve 9 executable as cylindrical components are. The spacing of the lower end of the closure element 8 of the sealing seat 11 depends on the Pivot angle of the rocker arm 10 and the distance from the Locking element 8 from the pivot axis of the rocker arm 10 from. Since the pivoting movement of the rocker arm into a vertical Stroke of the closure element 8 is transferred, the Sealing seat 10 are executed planar, during which the outlet opening 13 sealing area of the inner wall of the Housing 2 and the sealing area of this Exit channel 12 are shaped in the form of spheres. Due to the planar design of the sealing seat 11, this is Can be manufactured particularly accurately.

In Fig. 3 ist die Verschlußvorrichtung in einer weiteren Öffnungsposition dargestellt, bei der der Kipphebel 10 weiter aus seiner Verschlußposition verschwenkt ist und das untere Ende des Verschlußelementes 8 weiter von dem Dichtsitz 11 beabstandet ist. Hierdurch ist ein größerer Querschnittsbereich der seitlich an dem Austrittsstutzen 5 angeordneten Öffnung 6 freigegeben. In dieser Position kann auch ein höherviskoses Medium leicht das Verschlußelement 8 und letztlich die Austrittsöffnung 13 passieren. Damit ist die Verschlußvorrichtung in unterschiedliche Öffnungspositionen überführbar, in der jeweils Medien mit deutlich unterschiedlicher Viskosität dosiergenau dem Behälter entnehmbar sind. Der Querschnitt der Öffnung 6 kann dabei so bemessen sein, daß er mit dem durchströmbaren Querschnitt des Verschlußelementes 9 übereinstimmt, wobei das Verschlußelement 9 bei größtem Hub die Öffnung 6 vollständig freigibt.In Fig. 3 the closure device is in a further open position shown, in which the rocker arm 10 further out its closed position is pivoted and the lower end of the closure element 8 further apart from the sealing seat 11 is. This results in a larger cross-sectional area Opening 6 arranged laterally on the outlet connection 5 Approved. A higher viscosity can also be used in this position Medium lightly the closure element 8 and ultimately the outlet opening 13 happen. So that the closure device convertible into different opening positions in which media with clearly different viscosities each precisely can be removed from the container. The cross section of the Opening 6 can be dimensioned so that it with the flowable Cross section of the closure element 9 corresponds, the closure element 9 opening 6 at the greatest stroke fully releases.

Das Verschlußelement 8 besteht in dem gezeigten Ausführungsbeispiel aus dem gleichen Material wie der Kipphebel 10 und ist einteilig an diesem angeformt. Die Flexibilität des Verschlußelementes 8 wird dabei durch eine geeignete Bemessung der Wandstärke desselben erreicht. Das Verschlußelement 8 kann jedoch auch aus einem anderen Material als der Kipphebel 10 bestehen und kann an diesem beispielsweise durch Verklebung oder durch Preßsitz gehaltert werden.The closure element 8 is in the embodiment shown made of the same material as the rocker arm 10 and is molded in one piece on this. The flexibility of the closure element 8 is determined by a suitable design the wall thickness of the same. The closure element 8 can but also from a different material than the rocker arm 10 exist and can be on this for example by gluing or be held by a press fit.

Fig. 4 zeigt einen Schnitt der erfindungsgemäßen Verschlußvorrichtung, aus dem deutlich hervorgeht, daß sowohl das Gehäuse 2 als auch der Austrittsstutzen 5 der Verschlußvorrichtung jeweils einen kreisrunden Querschnitt aufweisen. Dabei ist ebenfalls ersichtlich, daß das Verschlußelement 8 sowie die dieses abdichtend umgebende Führungshülse 9 ebenfalls einen kreisrunden Querschnitt aufweisen, wobei das Verschlußrohr 8 am Umfang des Austrittsstutzens 5 angeordnet ist, wobei die Längsachse des Verschlußrohres 8 radial nach außen versetzt zum Umfang des Austrittsstutzens 5 angeordnet ist und das Verschlußrohr 8 in einem Teilbereich mit dem Anschlußstutzen 5 überlappt. Hierdurch ist im Dichtungsbereich des Rohres 8 eine exakte Führung gewährleistet, da die Führungshülse 9 das Verschlußelement 8 um mehr als seinen halben Umfang umgreift, zugleich ist bei gegebenem Hub des Verschlußelementes 8 ein vergleichsweise großer Querschnitt der Öffnung 6 für den Ausfluß des Mediums freigegeben. Des weiteren ist ersichtlich, daß der Kipphebel 10 mittels der Zapfen 14 schwenkbar gelagert ist, wobei die Verschwenkachse in der Mittelebene der Verschlußvorrichtung verläuft. Unterhalb der Zapfen 14 sind ebene Kreissegmente 15 an dem Kipphebel 10 einstückig angeformt, die der Halterung des Kipphebels 10 bei Einwirkung eines vertikal abwärts gerichteten Druckes dienen.4 shows a section of the closure device according to the invention, which clearly shows that both the housing 2 and the outlet nozzle 5 of the closure device each have a circular cross section. It is also seen that the closure element 8 and the this sealingly surrounding guide sleeve 9 also a have a circular cross section, the sealing tube 8 is arranged on the circumference of the outlet nozzle 5, the Longitudinal axis of the sealing tube 8 offset radially outwards is arranged to the extent of the outlet nozzle 5 and that Sealing tube 8 in a partial area with the connecting piece 5 overlaps. As a result, 8 is in the sealing area of the tube ensures exact guidance, since the guide sleeve 9 the Engages closure element 8 by more than half its circumference, at the same time is a given stroke of the closure element 8 comparatively large cross section of the opening 6 for the outflow released the medium. It can also be seen that the rocker arm 10 is pivotally mounted by means of the pin 14 is, the pivot axis in the central plane of the closure device runs. Below the pin 14 are flat Circular segments 15 integrally formed on the rocker arm 10, the the mounting of the rocker arm 10 under the action of a vertical serve downward pressure.

Wie in Fig. 5 zu sehen ist, werden die Kreissegmente 15 vor und hinter der Drehachse des Kipphebels 10 von Auflagern 16 unterstützt, die balkenförmig ausgebildet an der Innenwand des Gehäuses 2 einteilig angeformt sind. Die Auflager 16 weisen dabei eine mit den Kreissegmenten 15 korrespondierende bogenförmige Auflagefläche auf. An der Umfangsfläche der Kreissegmente 15 sind voneinander beabstandet mehrere Hinterschneidungen 17 angeordnet. Zwischen den Auflagern 16 ist eine Blattfeder 18 vorgesehen, in deren Scheitelpunkt ein Rastnocken 19 einteilig angeformt ist, der wahlweise unter Verschwenkung des Kipphebels 10 in eine der Hinterschneidungen 17 einführbar ist. Damit ist jeder der Sollstellungen, in die die Verschlußvorrichtung überführbar ist, eine definierte Verschwenkstellung des Kipphebels und eine damit korrespondierende Anordnung des Rastnockens 19 in einer der Hinterschneidungen 17 zugeordnet. Durch die Anordnung des Rastnockens 19 auf der Blattfeder 18 ist dabei die Rastsperre in beiden Verkipprichtungen des Verkipphebels leicht betätigbar und, da sie an der Innenwand des Gehäuses 2 angeordnet ist, vor äußeren Eingriffen geschützt. As can be seen in Fig. 5, the circular segments 15 are forward and behind the axis of rotation of the rocker arm 10 of supports 16 supports that are bar-shaped on the inner wall of the Housing 2 are integrally formed. The supports 16 point thereby an arcuate corresponding to the circle segments 15 Contact surface. On the circumferential surface of the circular segments 15 are a plurality of undercuts spaced from each other 17 arranged. Between the supports 16 is a leaf spring 18 is provided, at the apex of which a locking cam 19 is integrally formed, which is optionally pivoted by the Rocker arm 10 can be inserted into one of the undercuts 17 is. So that each of the target positions in which the locking device is transferable, a defined pivot position of the rocker arm and a corresponding arrangement assigned to the locking cam 19 in one of the undercuts 17. By arranging the locking cam 19 on the leaf spring 18 is the detent in both tilt directions of the Tilt lever easy to operate and, as it is on the inner wall the housing 2 is arranged, protected from external interference.
