Description

Die Erfindung betrifft eine Austragvorrichtung für ein flüssiges Medium nach dem Oberbegriff von Anspruch 1.The invention relates to a discharge device for a liquid medium according to the preamble of claim 1.

Gattungsgemäße Austragvorrichtungen sind aus dem Stand der Technik bekannt. Sie werden für pharmazeutische Flüssigkeiten verwendet, beispielsweise für Augen- und Nasentropfen. Durch den Austragvorgang wird bei gattungsgemäßen Austragvorrichtungen die Menge des in dem Mediumreservoir befindlichen Mediums verringert, so dass Luft nachströmen muss, um zu verhindern, dass das Mediumreservoir dauerhaft unter Unterdruck steht.Generic discharge devices are known from the prior art. They are used for pharmaceutical liquids, for example for eye and nose drops. In the case of generic discharge devices, the discharge process reduces the amount of medium in the medium reservoir so that air must flow in order to prevent the medium reservoir from being permanently under negative pressure.

Hierfür ist es bei den aus dem Stand der Technik bekannten Austragvorrichtungen vorgesehen, einen Druckausgleichskanal von einer äußeren Umgebung bis zum Mediumreservoir zu führen, durch den Luft nachströmen kann. Um eine Kontamination des Mediums zu verhindern, ist es bei gattungsgemäßen Austragvorrichtungen weiterhin bekannt, eine Filteranordnung im Bereich des Druckausgleichskanals vorzusehen, die mittels eines Bakterienfilters Mikrobakterien aus der einströmenden Luft filtert.For this purpose, it is provided in the known from the prior art discharge devices to guide a pressure equalization channel from an external environment to the medium reservoir, can flow through the air. In order to prevent contamination of the medium, it is further known in generic dispensing devices to provide a filter arrangement in the region of the pressure equalization channel, which filters microbacteria from the incoming air by means of a bacterial filter.

Bei gattungsgemäßen Austragvorrichtungen ist es nicht ganz auszuschließen, dass Medium bis an diesen Bakterienfilter gelangt. Dies gilt insbesondere für solche Austragvorrichtungen, die zur Benutzung bestimmungsgemäß in eine von ihrer Ruhelage abweichende Lage gebracht werden, so dass das die vormals oben angeordnete Auslassöffnung nach unten weist. Der zumeist in der Ruhelage oberhalb des Flüssigkeitsspiegels in das Mediumreservoir mündende Druckausgleichskanal liegt dann während der Benutzung unterhalb des Flüssigkeitsspiegels. Zwar bleibt bei einem Drehen der Austragvorrichtung üblicherweise zwischen dem Medium und dem Bakterienfilter ein Luftkissen vorhanden, welches einen unmittelbaren Kontakt der Flüssigkeit mit dem Bakterienfilter verhindert. Insbesondere bei solchen Austragvorrichtungen, bei denen das Medium im Mediumreservoir zur Durchführung eines Austragvorgangs unter Druck gesetzt wird, kann das Medium jedoch auch in Kontakt mit dem Bakterienfilter gelangen.In generic discharge devices, it is not completely ruled out that the medium reaches this bacterial filter. This applies in particular to those discharge devices which are intended to be brought into a position deviating from their rest position for use, so that the outlet opening previously arranged upwards points downwards. The usually in the rest position above the liquid level in the medium reservoir pressure-equalizing channel is then during use below the liquid level. Although, when the discharge device is rotated, an air cushion usually remains between the medium and the bacteria filter, which prevents direct contact of the liquid with the bacteria filter. In particular, in such discharge devices in which the medium is pressurized in the medium reservoir for carrying out a discharge process, however, the medium can also come into contact with the bacterial filter.

Diese Situation ist deshalb sehr nachteilig, da die geringe Porengröße des Bakterienfilters zu einer hohen Oberflächenspannung des Mediums in diesen Poren führt, was auch nach Rücküberführung der Austragvorrichtung in ihre Ruhelage einen Verbleib dieses Mediums am Bakterienfilter zur Folge hat. Diese Medium verhindert durch die genannte Oberflächenspannung dann den Eintritt von Luft in das Mediumreservoir, so dass ein Ausgleich für das ausgetragene Medium nicht mehr ausreichend stattfinden kann. Eine Vergrößerung der Porengröße ist jedoch problematisch, da dadurch das Eindringen von Bakterien in den Bakterienfilter wieder begünstigt würde.This situation is therefore very disadvantageous, since the small pore size of the bacterial filter leads to a high surface tension of the medium in these pores, which even after the return of the discharge in its rest position has a whereabouts of this medium on the bacterial filter result. This medium prevents by the surface tension mentioned then the entry of air into the medium reservoir, so that a compensation for the discharged medium can no longer take place sufficiently. Increasing the pore size, however, is problematic because it would favor the penetration of bacteria into the bacterial filter again.

Aus der DE 19642073 A1 ist eine Verschlusseinreichtung bekannt, die zu Belüftungszwecken eine für Flüssigkeiten bzw. Feststoffe undurchlässige, jedoch gasdurchlässige Membran umfasst. Die genannte Schrift schlägt hierzu insbesondere vor, Membranen beidseitig an einem Trägermaterial vorzusehen. Weiterhin wird vorgeschlagen, die Membranen oleophob auszugestalten.From the DE 19642073 A1 For example, a closure device is known which, for ventilation purposes, comprises a liquid-impermeable but gas-permeable membrane. The cited document proposes in particular to provide membranes on both sides of a substrate. Furthermore, it is proposed to design the membranes oleophobic.

Aus der FR 2890382 A1 ist ein Spender mit einem Filtersystem bekannt. Dieses Filtersystem weist mehrere Membranen auf, die flüssigkeitsdicht bzw. zur Filterung von Schadstoffen ausgebildet sein können. Diese Membranen liegen in einem Schichtverbund unmittelbar aneinander an.From the FR 2890382 A1 a dispenser is known with a filtration system. This filter system has a plurality of membranes, which may be formed liquid-tight or for filtering pollutants. These membranes are directly adjacent to one another in a layer composite.

Aufgabe und LösungTask and solution

Aufgabe der Erfindung ist es, eine gattungsgemäße Austragvorrichtung dahingehend weiterzubilden, dass die genannten Nachteile des Standes der Technik vermieden oder vermindert werden.The object of the invention is to develop a generic discharge device to the effect that the disadvantages of the prior art mentioned avoided or reduced.

Erfindungsgemäß wird dies durch eine Austragvorrichtung für ein flüssiges Medium nach Anspruch 1 erreicht. Die beiden voneinander durch einen Freiraum beabstandeten Filter dieser Austragvorrichtung sind derart angeordnet, dass die beim Druckausgleich durch den Druckausgleichskanal strömende Luft beide Filter durchdringen muss. Der Flüssigkeitspfad, entlang dessen während des Austragvorgangs das Medium vom Mediumspeicher zur Austragöffnung gelangt, ist vom Druckausgleichskanal separat ausgebildet, so dass das austretende Medium nicht durch den Flüssigkeitsfilter und den Bakterienfilter hindurchtreten muss, um zur Austragöffnung zu gelangen.According to the invention this is achieved by a discharge device for a liquid medium according to claim 1. The two spaced from each other by a free space filter this discharge device are arranged such that the air flowing through the pressure equalization channel during pressure equalization must penetrate both filters. The liquid path, along which the medium passes from the medium reservoir to the discharge opening during the discharge process, is formed separately from the pressure equalization channel, so that the exiting medium does not have to pass through the liquid filter and the bacteria filter in order to reach the discharge opening.

Die beiden Filter sind innerhalb des Druckausgleichskanals hintereinander angeordnet, so dass beim bestimmungsgemäßen Druckausgleich die einströmende Luft zunächst den Bakterienfilter und anschließend den Flüssigkeitsfilter durchquert. Auf umgekehrtem Weg kann die Flüssigkeit jedoch nicht bis zum Bakterienfilter gelangen, da sie bereits durch den Flüssigkeitsfilter aufgehalten wird.The two filters are arranged one behind the other within the pressure equalization channel, so that when the pressure is equalized, the inflowing air first passes through the bacteria filter and then through the liquid filter. In the opposite way, however, the liquid can not reach the bacteria filter, since it is already stopped by the liquid filter.

Erfindungsgemäß sind der Flüssigkeitsfilter und der Bakterienfilter durch einen Freiraum voneinander beabstandet, vorzugsweise um mindestens 0,5 mm, insbesondere um mindestens 1 mm. Diese Beabstandung verhindert, dass durch den Flüssigkeitsfilter hindurch gelangendes Medium unmittelbar mit dem Bakterienfilter in Kontakt kommt. Stattdessen kann eine begrenzte Menge des Mediums ohne nachteilige Wirkung auf den Bakterienfilter in den Zwischenbereich zwischen Flüssigkeitsfilter und Bakterienfilter gelangen, von wo diese Flüssigkeitsmenge beim Druckausgleich zurück in das Reservoir gedrückt wird.According to the invention, the liquid filter and the bacterial filter are spaced apart by a free space, preferably by at least 0.5 mm, in particular by at least 1 mm. This spacing prevents media passing through the liquid filter from coming into direct contact with the bacterial filter. Instead, a limited amount of the medium can reach the intermediate region between the liquid filter and the bacterial filter without adverse effect on the bacterial filter, from where this quantity of liquid is forced back into the reservoir during pressure compensation.

Vorzugsweise ist der Austragöffnung ein Auslassventil zugeordnet, welches ab einem Öffnungsüberdruck öffnet, wobei der Flüssigkeitsfilter derart ausgebildet ist, dass am Flüssigkeitsfilter anliegendes Medium mindestens bis zu diesem Öffnungsüberdruck nicht durch den Flüssigkeitsfilter hindurchtreten kann. Da der Öffnungsüberdruck des Auslassventils gleichzeitig auch den Maximaldruck bildet, der im Mediumreservoir auftreten kann, ist hierdurch gewährleistet, dass kein Medium bis zum Bakterienfilter gelangt.Preferably, the discharge opening is associated with an outlet valve which opens from an opening overpressure, wherein the liquid filter is designed such that at least up to this opening overpressure medium can not pass through the liquid filter on the liquid filter. Since the opening overpressure of the outlet valve simultaneously also forms the maximum pressure which can occur in the medium reservoir, this ensures that no medium reaches the bacteria filter.

Der Flüssigkeitsfilter ist vorzugsweise derart ausgebildet, dass am Flüssigkeitsfilter anliegendes Medium bis zu einem Überdruck von mindestens 0,5 bar, vorzugsweise bis zu einem Überdruck von mindestens 1,0 bar, nicht durch den Flüssigkeitsfilter hindurchtreten kann. Da der während eines Austragvorgangs im Mediumreservoir üblicherweise gegebenen maximale Überdruck bei den meisten Austragvorrichtungen unter 0,5 bar, zumindest aber unter 1,0 bar liegt, führt eine solche Gestaltung des Flüssigkeitsfilters dazu, dass keinerlei Medium bis zum Bakterienfilter gelangen kann, selbst wenn das Medium während der Austragvorgangs unmittelbar am Flüssigkeitsfilter anliegt und druckbeaufschlagt wird.The liquid filter is preferably designed in such a way that medium applied to the liquid filter can not pass through the liquid filter up to an overpressure of at least 0.5 bar, preferably up to an overpressure of at least 1.0 bar. Since the maximum overpressure usually given during a discharge process in the medium reservoir is less than 0.5 bar in most discharge devices, but at least less than 1.0 bar, such a design of the liquid filter means that no medium can reach the bacteria filter, even if that Medium during the discharge process is applied directly to the liquid filter and is pressurized.

Selbst wenn der Flüssigkeitsfilter keine vollständige Sperre für die Flüssigkeit bietet, so vermindert er jedoch den Druck, mit dem die Flüssigkeit nach etwaigem Durchqueren des Flüssigkeitsfilters gegen den Bakterienfilter gedrückt wird, so dass ein Eindringen der Flüssigkeit in die Poren des Bakterienfilters nicht zu befürchten ist. Besonders vorteilhaft ist die Verwendung der beschriebenen Filteranordnung bei Austragvorrichtungen, die bestimmungsgemäß bezüglich ihrer Lage verändert werden, beispielsweise so, dass die Mündung des Druckausgleichskanals während der Benutzung unterhalb des Flüssigkeitsspiegels des Mediums liegt.However, even if the liquid filter does not provide a complete barrier to the liquid, it reduces the pressure at which the liquid is forced against the bacterial filter after passing through the liquid filter, so that penetration of the liquid into the pores of the bacteria filter is not to be feared. Particularly advantageous is the use of the described filter arrangement in discharge devices that are changed as intended with respect to their position, for example, so that the mouth of the pressure compensation channel is below the liquid level of the medium during use.

Die Filter können als Filter aus einem porösen Material, beispielsweise einem Sintermaterial, ausgebildet sein. Auch Gewebemembrane und andere Filtermaterialien können Verwendung finden.The filters can be designed as filters made of a porous material, for example a sintered material. Tissue membranes and other filter materials can also be used.

Erfindungsgemäß ist vorgesehen, dass der Flüssigkeitsfilter und der Bakterienfilter jeweils Filterporen aufweisen, wobei die mittlere Porengröße der Filterporen des Flüssigkeitsfilters größer ist als die mittlere Porengröße der Filterporen des Bakterienfilters. Da die Porengröße maßgeblich die Oberflächenspannung einer am Filter anliegenden und in die Poren gelangenden Flüssigkeit beeinflusst und deshalb der erforderliche Differenzdruck zwischen den beiden Seiten des Filters zur Ablösung der Flüssigkeit umso größer sein muss, je kleiner die Filterporen sind, ist es von Vorteil, am Flüssigkeitsfilter größere Poren vorzusehen. Wenn nach einer zwischenzeitlichen Überkopfposition der Austragvorrichtung eine Flüssigkeitsschicht am Flüssigkeitsfilter verbleibt, kann diese aufgrund der vergleichsweise großen Poren schon durch einen recht geringen Differenzdruck zwischen Außenumgebung und Mediumreservoir vom Filter abgelöst werden.According to the invention, it is provided that the liquid filter and the bacterial filter each have filter pores, wherein the average pore size of the filter pores of the liquid filter is greater than the mean pore size of the filter pores of the bacterial filter. Since the pore size significantly affects the surface tension of a liquid applied to the filter and entering the pores and therefore the required differential pressure between the two sides of the filter to dissolve the liquid must be greater, the smaller the filter pores, it is advantageous to the liquid filter provide larger pores. If, after an intermediate overhead position of the discharge device, a liquid layer remains on the liquid filter, it can already be detached from the filter due to the comparatively large pores by a rather small differential pressure between the outside environment and the medium reservoir.

Als besonders vorteilhaft hat sich ein mittlerer Porendurchmesser beim Flüssigkeitsfilter von mindestens 6 µm. Besonders von Vorteil ist es, wenn der Flüssigkeitsfilter einen mittleren Porendurchmesser größer 10 µm, insbesondere größer 15 µm aufweist. Diese vergleichsweise große Porengröße führt auf dem Flüssigkeitsfilter zu einer vorteilhaft geringen Oberflächenspannung, so dass ein Flüssigkeitsfilm auf der dem Bakterienfilter abgewandeten Seite des Flüssigkeitsfilters zuverlässig beim Druckausgleich entfernt wird, so dass nachfolgend Luftblasen zum Zweck des Drucksausgleichs eintreten können.Particularly advantageous is an average pore diameter at the liquid filter of at least 6 microns. It is particularly advantageous if the liquid filter has an average pore diameter of greater than 10 μm, in particular greater than 15 μm. This comparatively large pore size leads to an advantageously low surface tension on the liquid filter, so that a liquid film on the side facing away from the bacterial filter of the liquid filter is reliably removed during pressure equalization, so that subsequently air bubbles can occur for the purpose of pressure equalization.

In Hinblick auf den Bakterienfilter hat sich ein mittlerer Porendurchmesser von höchsten 5 µm, vorzugsweise von höchstens 1 µm, insbesondere von höchstens 0,2 µm als vorteilhaft herausgestellt. Je nach konkretem Anwendungszweck können beliebige Kombinationen der angegebenen Grenzwerte zweckmäßig sein.With regard to the bacterial filter, an average pore diameter of at most 5 μm, preferably at most 1 μm, in particular at most 0.2 μm, has proven to be advantageous. Depending on the specific application, any combination of the specified limits may be appropriate.

Bei einer Weiterbildung der Erfindung sind der Flüssigkeitsfilter und der Bakterienfilter Teil einer Filterbaueinheit, die in den Druckausgleichskanal eingesetzt sind. Die Filtereinheit kann somit während der Montage als Ganzes gehandhabt werden und den gewünschten Abstand zwischen dem Flüssigkeitsfilter und dem Bakterienfilter bereits fest vorgeben. Die Filterbaueinheit kann auch derart in den Druckausgleichskanal eingesetzt sein, dass sie selbst eine Verlängerung des Druckausgleichskanals bildet. Zu diesem Zweck ist sie vorzugsweise rohrförmig ausgebildet.In a further development of the invention, the liquid filter and the bacterial filter are part of a filter assembly, which are inserted into the pressure equalization channel. The filter unit can thus be handled as a whole during assembly and already set the desired distance between the liquid filter and the bacteria filter. The filter assembly may also be inserted into the pressure equalization channel such that it itself forms an extension of the pressure equalization channel. For this purpose, it is preferably tubular.

Bei einer Weiterbildung der Erfindung ist der Druckausgleichskanal zumindest abschnittsweise als Kapillarkanal ausgebildet. Durch einen solchen Kapillarkanal wird das Austreten von im Mediumreservoir verdunstetem Medium behindert. Als Kapillarkanal wird dabei ein Kanal von mindestens 10 mm Länge angesehen, dessen mittlere Querschnittsfläche kleiner 1 mm2 ist, vorzugsweise kleiner 0,5 mm2. Das Vorsehen eines Kapillarkanals führt dazu, dass der Druckausgleichskanal nicht durch ein vergleichsweise aufwendiges Ventil gegenüber dem Mediumreservoir abgedichtet werden muss. Dies ist insbesondere deshalb von Vorteil, da ein solches Ventil in Hinblick auf einen funktionierenden Druckausgleich schwierig auszulegen ist.In a further development of the invention, the pressure equalization channel is at least partially formed as a capillary channel. By such a capillary channel the escape of medium evaporated in the medium reservoir is hindered. As a capillary channel, a channel of at least 10 mm in length is considered, whose average cross-sectional area is less than 1 mm 2 , preferably less than 0.5 mm 2 . The provision of a capillary channel means that the pressure equalization channel does not have to be sealed by a comparatively complicated valve in relation to the medium reservoir. This is particularly advantageous because such a valve is difficult to design in terms of a functioning pressure equalization.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Weitere Aspekte und Vorteile der Erfindung ergeben sich außer aus den Ansprüchen auch aus der nachfolgenden Beschreibung zweier bevorzugter Ausführungsbeispiele der Erfindung, die anhand der Figuren erläutert werden. In den Figuren zeigt:

Fig. 1.
eine erste Ausführungsform einer erfindungsgemäßen Austragvorrichtung in einer geschnittenen Seitenan- sicht und
Fig. 2a und 2b
eine zweite Ausführungsform einer erfindungsgemä- ßen Austragvorrichtung in zwei geschnittenen Seiten- ansichten
Other aspects and advantages of the invention will become apparent from the claims and from the following description of two preferred embodiments of the invention, which are explained with reference to FIGS. In the figures shows:
Fig. 1.
a first embodiment of a discharge device according to the invention in a sectional side view and
Fig. 2a and 2b
A second embodiment of an inventive discharge in two sectional side views

In Figur 1 dargestellt ist eine Austragvorrichtung 10, die über ein flaschenartiges Mediumreservoir 20 sowie einen darauf aufgerasteten Dosierkopf 30 verfügt.In FIG. 1 illustrated is a discharge device 10, which has a bottle-like medium reservoir 20 and a dosed thereon 30 dosing.

Am Dosierkopf 30 ist eine Auslassöffnung 32 vorgesehen, die durch ein Ventil 34 verschlossen ist, bis der Druck im Medium in einer mit dem Mediumreservoir verbundenen Ventilkammer 36 eine vorgegebene Höhe erreicht hat. Sobald dies der Fall ist, wird das Ventil 34 vom Flüssigkeitsdruck gegen eine Federkraft aufgedrückt und der Austragvorgang beginnt. Bei der dargestellten Austragvorrichtung 10 ist vorgesehen, dass diese während des Austragvorgangs derart gehalten wird, so dass die Auslassöffnung 32 nach unten weist.On the dosing head 30, an outlet opening 32 is provided which is closed by a valve 34 until the pressure in the medium has reached a predetermined height in a valve chamber 36 connected to the medium reservoir. Once this is the case, the valve 34 is pressed by the liquid pressure against a spring force and the discharge process begins. In the illustrated discharge device 10 it is provided that it is held during the discharge process such that the outlet opening 32 points downward.

Die Druckbeaufschlagung des Mediums im Mediumreservoir 20 findet bei der dargestellten Austragvorrichtung dadurch statt, dass das Mediumreservoir 20 manuell zusammengedrückt wird. Das Mediumreservoir 20 ist über einen in Fig. 1 nicht dargestellten Kanal mit der Ventilkammer 36 verbunden, so dass das Zusammendrücken des Mediumreservoirs 20 eine Druckerhöhung sowohl im Mediumreservoir 20 als auch in der Ventilkammer 36 bewirkt. Alternative Ausführungsformen können jedoch auch ein anderweitig geartetes Druckerzeugungsmittel vorsehen, beispielsweise eine Kolbenpumpe, die zwischen dem Mediumreservoir und der Austrittsöffnung 32 angeordnet ist.The pressurization of the medium in the medium reservoir 20 takes place in the discharge device shown by the fact that the medium reservoir 20 is compressed manually. The medium reservoir 20 is via an in Fig. 1 not shown channel connected to the valve chamber 36, so that the compression of the medium reservoir 20 causes a pressure increase in both the medium reservoir 20 and in the valve chamber 36. Alternative embodiments may, however, also provide a different type of pressure generating means, for example a piston pump, which is arranged between the medium reservoir and the outlet opening 32.

Im Dosierkopf 30 ist ein Druckausgleichskanal 40 vorgesehen, durch den hindurch entlang der Pfeile 42a, 42b, 42c Luft aus einer Umgebung in das Mediumreservoir einströmen kann. Dadurch kann die zuvor ausgetragene Flüssigkeitsmenge durch nachströmende Luft ersetzt werden, so dass sich im Mediumreservoir nach einem Austragvorgang wieder der Normaldruck einstellt. Der Druckausgleichskanal 40 dient lediglich dem Einlass von Luft. Flüssiges Medium, welches vom Mediumreservoir 20 zur Ventilkammer 36 geleitet und durch die Austragöffnung 32 ausgegeben wird, wird hierfür nicht durch den Druckausgleichskanal 40 und die nachfolgend noch beschriebenen Filter 50, 52 hindurchgeführt.In the dosing head 30, a pressure equalization channel 40 is provided, through which air can flow from an environment into the medium reservoir along the arrows 42a, 42b, 42c. As a result, the previously discharged liquid quantity can be replaced by air flowing in, so that the normal pressure is restored in the medium reservoir after a discharge process. The pressure equalization channel 40 only serves for the admission of air. Liquid medium, which is conducted from the medium reservoir 20 to the valve chamber 36 and discharged through the discharge opening 32, is not passed through the pressure equalization channel 40 and the filters 50, 52 described below.

Im Druckausgleichskanal 40 ist eine Filterbaueinheit 44 eingeschoben, welche durch einen Presssitz an der dargestellten Position gehalten wird. Diese Filterbaueinheit weist ein zylinderförmigen Rohrabschnitt 44a auf, in dem kaskadiert hintereinander zwei Filter 50, 52 angeordnet sind. Die einströmende Luft muss beide Filter 50, 52 durchqueren, um in das Mediumreservoir 20 zu gelangen. Der obere Filter 50 ist von dem Kunststoffmaterial des Rohrabschnitts 44a umspritzt, während der untere Filter auf der Stirnfläche befestigt ist, beispielsweise mittels einer Klebverbindung.In the pressure equalization channel 40, a filter assembly 44 is inserted, which is held by a press fit in the position shown. This filter assembly has a cylindrical pipe section 44a, in which two filters 50, 52 are arranged in cascade one behind the other. The incoming air must pass through both filters 50, 52 to enter the medium reservoir 20. The upper filter 50 is overmolded by the plastic material of the tubular section 44a, while the lower filter is fastened on the end face, for example by means of an adhesive bond.

Bei dem bezogen auf die Figur 1 oberen Filter 50 handelt es sich um einen Bakterienfilter, also einen Filter, der kontaminierende Bestandteile aus der Luft zumindest zum Teil herausfiltert. Idealerweise ist er hierzu aus einem porösen Material gefertigt, welches eine Porengröße von 0,5 bis 1,5 µm aufweist. Je nach Anforderungen an die dekontaminierende Wirkung können auch andere Porengrößen vorgesehen sein. Je kleiner die Porengrößen des Bakterienfilters sind, desto vorteilhafter ist der untere Filter 52, der einen Flüssigkeitsfilter mit einer mittleren Porengröße von etwa 15 µm bildet. Dieser Flüssigkeitsfilter 52 verhindert in einer Überkopflage, in der die Auslassöffnung 32 nach unten weist, dass das Medium im Mediumreservoir 20 ungehindert bis zum Bakterienfilter 50 gelangen kann. Stattdessen gelangt es lediglich bis zum Flüssigkeitsfilter 52 und wird allenfalls in sehr geringer Menge bei der Druckbeaufschlagung des Mediums durch den Flüssigkeitsfilter 52 hindurchgedrückt. Selbst in einem solchen Fall reicht diese Menge der Flüssigkeit jedoch nicht aus, um den Bakterienfilter 50 vollflächig zu benetzen oder gar in die Poren des Bakterienfilters 50 eindringen zu können.With respect to the FIG. 1 Upper filter 50 is a bacterial filter, that is, a filter that at least partially filters contaminating components out of the air. Ideally, it is made of a porous material, which has a pore size of 0.5 to 1.5 microns. Depending on the requirements for the decontaminating effect, other pore sizes may be provided. The smaller the pore sizes of the bacteria filter, the more advantageous is the lower filter 52, which forms a liquid filter with an average pore size of about 15 μm. This liquid filter 52 prevents in an overhead position, in which the outlet opening 32 points downward, that the medium in the medium reservoir 20 can unhindered reach the bacteria filter 50. Instead, it only reaches the liquid filter 52 and is pushed through the liquid filter 52 at most in a very small amount when the medium is pressurized. However, even in such a case, this amount of liquid is not sufficient to wet the bacterial filter 50 over the entire surface or even to be able to penetrate into the pores of the bacterial filter 50.

Sobald die Austragvorrichtung nach einem Austragvorgang wieder in ihre in der Figur dargestellte ursprüngliche Lage zurückgedreht wird und die Druckbeaufschlagung des Mediums wegfällt, wird durch den sich dann im Mediumreservoir 20 einstellenden Unterdruck Luft durch den Druckausgleichskanal 40 angesogen. Ein eventuell auf dem Flüssigkeitsfilter 52 noch vorhandener Flüssigkeitsfilm wird dabei vom Filter 52 gelöst. Hierzu bedarf es keines großen Unterdrucks im Mediumreservoir 20, da die Poren des Flüssigkeitsfilters 52 vergleichsweise groß sind, so dass nur eine geringe Oberflächenspannung an der zum Flüssigkeitsfilter hinweisenden Seite des verbleibenden Flüssigkeitsfilms besteht.As soon as the discharge device is returned to its original position shown in the figure after a discharge operation and the pressurization of the medium is eliminated, air is sucked through the pressure equalization channel 40 by the negative pressure which is then established in the medium reservoir 20. Any liquid film still present on the liquid filter 52 is thereby released from the filter 52. For this purpose, there is no need for a large negative pressure in the medium reservoir 20, since the pores of the liquid filter 52 are comparatively large, so that there is only a small surface tension at the side of the remaining liquid film facing the liquid filter.

Nach Entfernen des Flüssigkeitsfilms kann die für den Druckausgleich erforderliche Luftmenge ungehindert durch den Druckausgleichskanal 40 in das Mediumreservoir 20 gelangen. Sofern zuvor Flüssigkeit zwischen die Filter 50, 52 gelangt ist, wird diese dabei zum Teil zurück in das Mediumreservoir 20 gedrückt.After removal of the liquid film, the amount of air required for pressure equalization can pass unimpeded through the pressure equalization channel 40 into the medium reservoir 20. If liquid has previously passed between the filters 50, 52, this is in part pressed back into the medium reservoir 20.

Die Ausführungsform der Fig. 2a und 2b ist weitgehend identisch zu der Ausführungsform der Fig. 1 aufgebaut. Da sich jedoch einige Aspekte dieser zweiten Ausführungsform geringfügig anders realisiert sind und/oder besser erkennbar sind, werden diese Aspekte an dieser zweiten Ausführungsform nochmals erläutert. Soweit nicht anders erwähnt, sind die Ausführungsformen der Fig. 1 und 2a / 2b funktionell identisch aufgebaut.The embodiment of the Fig. 2a and 2 B is largely identical to the embodiment of the Fig. 1 built up. However, since some aspects of this second embodiment are realized slightly differently and / or are more apparent, these aspects will be explained again in this second embodiment. Unless otherwise stated, the embodiments of the Fig. 1 and 2a / 2 B functionally identical.

Die Fig. 2a und 2b zeigen diese zweite Ausführungsform mit jeweils unterschiedlichen Schnittebenen.The Fig. 2a and 2 B show this second embodiment, each with different cutting planes.

Die Schnittebene der Fig. 2a dient der Verdeutlichung des Medienpfades 43, entlang dessen das Medium bei Kraftbeaufschlagung des Mediumreservoirs 20 in Überkopfstellung austritt. Das Medium tritt dabei in den an das Mediumreservoir 20 angrenzenden Austrittskanal 21 ein und gelangt von dort aus durch eine Radialbohrung 22 und einen schmalen Spalt 23 in die Ventilkammer 36, aus der heraus es durch die Austragöffnung 32 hindurch ausgetragen wird. Die Pfeile 43a bis 43d verdeutlichen diesen Medienpfad.The cutting plane of the Fig. 2a serves to illustrate the media path 43, along which the medium emerges when force applied to the medium reservoir 20 in the overhead position. The medium enters the adjacent to the medium reservoir 20 outlet channel 21 and passes from there through a radial bore 22 and a narrow gap 23 in the valve chamber 36, from which it is discharged through the discharge opening 32 therethrough. The arrows 43a to 43d illustrate this media path.

Der nachfolgende Druckausgleich ist anhand der Darstellung der Fig. 2b verdeutlicht. Der Druckausgleichskanal 40 dieser zweiten Ausführungsform verläuft etwas anders als bei der Ausführungsform der Fig. 1. Der Druckausgleichskanal weist entsprechend der Gestaltung der Fig. 1 einen axialen Kanalabschnitt 40a auf, der mit einer Ventilgegenkammer 40c durch eine Bohrung 40b verbunden ist. Diese Ventilgegenkammer 40c ist über eine radiale Bohrung 40d, einen als Kapillarkanal wirkenden Ringkanal 40e sowie eine Einlassbohrung 40f mit der Umgebung verbunden. Der sich nach einem Austragvorgang einstellende Unterdruck im Mediumreservoir 20 führt dazu, dass Luft entlang dieses Druckausgleichskanals und entlang der Pfeile 42a - 42d in das Mediumreservoir nachströmt. Dabei durchquert die Luft in der zur Ausführungsform der Fig. 1 beschriebenen Art und Weise die Filter 50, 52.The subsequent pressure compensation is based on the representation of Fig. 2b clarified. The pressure-equalizing passage 40 of this second embodiment is slightly different from the embodiment of FIG Fig. 1 , The pressure equalization channel has according to the design of Fig. 1 an axial passage portion 40a connected to a counter valve chamber 40c through a bore 40b. This valve counter chamber 40c is connected to the environment via a radial bore 40d, an annular channel 40e acting as a capillary channel and an inlet bore 40f. The negative pressure occurring in the medium reservoir 20 after a discharge process causes air to flow downstream along this pressure equalization channel and along the arrows 42a-42d into the medium reservoir. In this case, the air traverses in the embodiment of the Fig. 1 described manner the filters 50, 52nd

Somit besteht eine vollständige Trennung zwischen dem Pfad 42a - 42d, durch den hindurch Luft zum Zwecke des Druckausgleichs in das Mediumreservoir 20 strömt, und dem Medienpfad 43a - 43d, entlang dessen das flüssige Medium aus dem Mediumreservoir 20 an die Umgebung abgegeben wird.Thus, there is a complete separation between the path 42a-42d, through which air flows into the medium reservoir 20 for the purpose of pressure equalization, and the media path 43a-43d, along which the liquid medium is discharged from the medium reservoir 20 to the environment.

Wie auch bei der Ausführungsform der Fig. 1 ist der Druckausgleichskanal 40, 40a-40f stets für den Luftdurchfluss offen. Es wird allerdings durch den Kapillarkanalabschnitt 40e wirksam verhindert, dass relevante Mengen des Mediums, die innerhalb des Mediumreservoirs 20 verdunstet sind, aus der Austragvorrichtung 10 austreten können.As with the embodiment of the Fig. 1 the pressure equalization channel 40, 40a-40f is always open for the air flow. However, it is effectively prevented by the capillary channel portion 40e that relevant amounts of the medium, which have evaporated within the medium reservoir 20, can escape from the discharge device 10.
