Description

Die Erfindung betrifft eine Mehrkammer-Ampulle für portionierte Flüssigkeiten, mit einer äußeren Hülse aus elastischem Material, die im Inneren eine Kammer aufweist, die sich längs einer Achse erstreckt und die bodenseitig mit einem Boden verschlossen ist, und mit einem Verschlußelement, das die äußere Hülse kopfseitig verschließt und das einen Micropinsel aufweist, der an der Spitze ein flüssigkeitsaufnehmendes Element besitzt.The invention relates to a multi-chamber ampoule for portioned liquids, with an outer sleeve made of elastic material, inside a chamber has, which extends along an axis and the bottom with a Bottom is closed, and with a closure element that the outer Closes the sleeve on the head side and has a micro brush attached to the Tip has a liquid-absorbing element.

Es ist eine derartige Mehrkammer-Ampulle aus der DE-U-92 02 654 bekannt. Bei der bekannten Ampulle wird der Kammerhohlraum durch die eingefüllte Flüssigkeit selbst in zwei Kammern unterteilt. In der unteren Kammer befindet sich die portionierte Flüssigkeitsmenge und oberhalb der Flüssigkeit Luft.Such a multi-chamber ampoule is known from DE-U-92 02 654. In the known ampoule, the chamber cavity is filled in by the one Liquid itself divided into two chambers. Located in the lower chamber the portioned amount of liquid and air above the liquid.

Bestimmte Flüssigkeiten sind aber weitestgehend unter Luftabschluß einzufüllen. Nachteilig bei der bekannten Ampulle ist, daß aufgrund des Micropinsels, der in den Kammerhohlraum ragt, zuviel von der Flüssigkeit eingefüllt werden müßte, um die Luft weitestgehend zu verdrängen. Ein anderer Nachteil ist, daß bei einer übermäßigen Füllung der Schaft oder das Kopfteil des Micropinsels mit benetzt wird, weshalb es bei der Entnahme zu unerwünschten Abtropferscheinungen kommen kann.However, certain liquids are largely sealed off from the air fill in. A disadvantage of the known ampoule is that due to the Micro brush protruding into the chamber cavity, too much of the liquid would have to be filled in to largely displace the air. Another The disadvantage is that the shaft or the head part is overfilled of the micro brush is wetted with, which is why it is removed when it is removed unwanted draining symptoms can occur.

Daher ist es Aufgabe der Erfindung, eine Mehrkammer-Ampulle zu schaffen, bei der die Flüssigkeit trotz des vorhandenen Micropinsels weitestgehend unter Luftabschluß portioniert abfüllbar ist.It is therefore an object of the invention to provide a multi-chamber ampoule, where the liquid is largely below despite the existing micro brush Airtight can be filled in portions.

Die Aufgabe der Erfindung wird durch die Merkmale des Anspruchs 1 gelöst.The object of the invention is solved by the features of claim 1.

Erfindungsgemäß wird eine Mehrkammer-Ampulle geschaffen, bei der der Micropinsel getrennt von der portionierten Flüssigkeit in einer unteren Kammer einer äußeren Hülse aufbewahrt wird. Der Micropinsel ist in eine hohle und kolbenförmige innere Hülse eingelagert, die ein verschiebbares Verschlußelement für die äußere Hülse mit der unteren Kammer bildet. Die innere Hülse ist als gleitbarer Kolben in der äußeren Hülse eingelagert. Dabei bildet die innere Hülse selbst eine zweite und obere Kammer, in die der Micropinsel mit seiner Spitze ragt.According to the invention, a multi-chamber ampoule is created in which the Micro brush separated from the portioned liquid in a lower chamber an outer sleeve is kept. The micro brush is in a hollow and Piston-shaped inner sleeve which is slidable Closure element for the outer sleeve forms with the lower chamber. The inner sleeve is embedded as a slidable piston in the outer sleeve. there the inner sleeve itself forms a second and upper chamber into which the Micro brush with its tip protrudes.

Wesentlich ist, daß die Wandung der inneren Hülse radiale Bohrungen aufweist, die von der Wandung der äußeren Hülse abgedichtet werden. Durch Einschieben des Micropinsels wird die kolbenähnliche innere Hülse in die darunterliegende Flüssigkeit gepreßt. Dabei weitet sich die äußere elastische Wandung der äußeren Hülse bzw. die Wandung der inneren Hülse wird nach Innen gepreßt. So entsteht ein kleiner Wandungsspalt, über den die Flüssigkeit durch die Bohrungen hindurch, in die Kammer strömen kann, die den Micropinsel enthält.It is essential that the wall of the inner sleeve has radial bores has, which are sealed by the wall of the outer sleeve. By Pushing the micropinel into the piston-like inner sleeve liquid underneath pressed. The outer elastic widens Wall of the outer sleeve or the wall of the inner sleeve becomes after Pressed inside. This creates a small wall gap over which the liquid through the holes, can flow into the chamber that the Includes micro brush.

Durch vollständiges Absenken der inneren Hülse strömt die gesamte Flüssigkeit aus der ersten Kammer der äußeren Hülse in die zweite Kammer der inneren Hülse. Das Aufweiten des Wandungsspaltes zwischen der inneren und äußeren Hülse wird durch eine Dichtlippe im unteren Bereich der inneren Hülse unterstützt, wenn die Dichtlippe aus der zugehörigen Dichtnut verlagert wurde.By completely lowering the inner sleeve, the entire flows Liquid from the first chamber of the outer sleeve into the second chamber the inner sleeve. The widening of the wall gap between the inner and outer sleeve is covered by a sealing lip in the lower area of the inner Sleeve supports when the sealing lip moves out of the associated sealing groove has been.

In vorteilhafter Weise läßt sich mit der Erfindung die zu portionierende Flüssigkeit unter einem minimalen Lufteinschluß und getrennt von dem Micropinsel lagern. Der Micropinsel bildet selbst das Werkzeug, die innere Hülse abzusenken.The portion to be portioned can advantageously be obtained with the invention Liquid under minimal air entrapment and separate from that Store micro brushes. The micro brush itself forms the tool, the inner one Lower the sleeve.

Die Erfindung gestattet sogar das Aufbewahren einer Zweikomponenten-Flüssigkeit. Die eine Komponente befindet sich in der unteren Kammer der äußeren Hülse, die von der inneren Hülse verschlossen wird. Die andere Komponente ist in der zweiten Kammer eingelagert, die die innere Hülse aufweist und die den Micropinsel enthält.The invention even allows a two-component liquid to be stored. One component is in the lower chamber of the outer sleeve, which is closed by the inner sleeve. The other Component is stored in the second chamber, which is the inner sleeve and which contains the micro brush.

Fig. 1 zeigt einen Längsschnitt durch eine Mehrkammer-Ampulle, die eine äußere Hülse 2 aufweist. Die äußere Hülse 2 besitzt einen Standfuß 14 und einen zylindrischen Hohlraum, der eine erste Kammer 12 bildet. In der ersten Kammer 12 ist eine Flüssigkeit 17 angeordnet. Die Kammer 12 besitzt vorzugsweise einen planen Boden 31. Die äußere Hülse 2 erstreckt sich längs der Achse y und ist oben offen. 1 shows a longitudinal section through a multi-chamber ampoule which has an outer sleeve 2. The outer sleeve 2 has a stand 14 and a cylindrical cavity which forms a first chamber 12. A liquid 17 is arranged in the first chamber 12. The chamber 12 preferably has a flat bottom 31. The outer sleeve 2 extends along the axis y and is open at the top.

In der äußeren Hülse 2, die eine im wesentlichen glatte Innenwandung aufweist, ist eine kolbenförmige innere Hülse 3 eingelagert. Die innere Hülse 3 ist längs der Achse y verschiebbar in der äußeren Hülse 2 gelagert. Die Unterseite 30 der inneren Hülse 3 bildet den Abschluß für die eingelagerte Flüssigkeit 17 in der Kammer 12. Da die äußere Wandung der inneren Hülse 3 flüssigkeitsdicht an der inneren Wandung der äußeren Hülse 2 anliegt, bildet die innere Hülse 3 ein Verschlußelement für die Kammer 12 der äußeren Hülse.In the outer sleeve 2, which has a substantially smooth inner wall has a piston-shaped inner sleeve 3 is embedded. The inner sleeve 3 is slidably mounted in the outer sleeve 2 along the axis y. The Bottom 30 of the inner sleeve 3 forms the conclusion for the stored Liquid 17 in the chamber 12. Since the outer wall of the inner sleeve 3rd rests liquid-tight on the inner wall of the outer sleeve 2, forms the inner sleeve 3 is a closure element for the chamber 12 of the outer Sleeve.

Die innere Hülse 3 ist wie die äußere Hülse 2 nach oben offen, jedoch steckt abgedichtet ein Micropinsel 1 mit seinem Kopfteil 28 und seinem Schaft 27 in der inneren Hülse 3, deren Öffnung 33 somit verschlossen wird. Der Micropinsel 1 weist einen stielförmigen Handgriff 26 auf, der aus der Öffnung 32 der äußeren Hülse 2 ragt. Unter Bildung einer Hinterschneidung 24 legt sich die äußere Hülse 2 abdichtend an den Handgriff 26 an. Jedoch ist es möglich, eine entsprechend weite Öffnung 25 vorzusehen, um den Micropinsel 1 aus der äußeren Hülse 2 abziehen zu können.The inner sleeve 3, like the outer sleeve 2, is open at the top, but is stuck seals a micro brush 1 with its head part 28 and its shaft 27 in the inner sleeve 3, the opening 33 is thus closed. The Micro brush 1 has a handle-shaped handle 26 that comes out of the opening 32 of the outer sleeve 2 protrudes. Forms an undercut 24 the outer sleeve 2 sealingly on the handle 26. However, it is possible to provide a correspondingly wide opening 25 to the micro brush 1 from the to be able to pull off the outer sleeve 2.

Zwischen der inneren Wandung der inneren Hülse 3 und dem Micropinsel 1 ist eine Abdichtung vorgesehen, die in Fig.1 aus einer Dichtlippe 5 und einer Dichtnut 6 besteht, die das Kopfteil 28 als Ringnut umläuft. Je nach Bedarf, können weitere Abdichtungen vorgesehen sein.Is between the inner wall of the inner sleeve 3 and the micro brush 1 a seal is provided, which in Figure 1 consists of a sealing lip 5 and a Sealing groove 6, which runs around the head part 28 as an annular groove. As required, further seals can be provided.

In gleicher Weise ist eine Abdichtung zwischen der inneren Wandung der äußeren Hülse 2 und der äußeren Wandung der inneren Hülse 3 vorgesehen. Die Abdichtung besteht in Fig.1 aus der Dichtlippe 7 und der Dichtnut 8, die gleichzeitig bewirken, daß die innere Hülse 3 in einer oberen Höhenposition gehalten wird. Nach Fig.1 sind parallel zu der untersten Dichtnut 8 höher angeordnete Nuten vorgesehen, die in Form von Rastnuten 9 Rastelemente bilden. Mittels der Rastnuten 9 läßt sich die kolbenförmige innere Hülse 3 schrittweise absenken. In the same way is a seal between the inner wall of the outer sleeve 2 and the outer wall of the inner sleeve 3 is provided. The seal consists of the sealing lip 7 and the sealing groove 8 in FIG at the same time cause the inner sleeve 3 in an upper height position is held. According to Fig.1 are parallel to the lowest sealing groove 8 higher Arranged grooves provided, the 9 locking elements in the form of locking grooves form. By means of the locking grooves 9, the piston-shaped inner sleeve 3rd lower gradually.

Der Boden 31 der äußeren Hülse 2 ist an die Form der Unterseite 30 der inneren Hülse 3 so angepaßt, daß im vollständig abgesenkten Zustand kein Spalt verbleibt. Vorzugsweise sind der Boden 31 und die Unterseite 30 plan, können aber auch z.B. kugelig gekrümmt sein. Wenn die Unterseite 30 plan auf dem Boden 31 aufliegt, kommt die oberste Rastnut 9 mit der Dichtlippe 5 in Eingriff. D. h., der Hubweg der Unterseite 30 entspricht dem Abstand der Dichtnut 8 zur obersten Rastnut 9.The bottom 31 of the outer sleeve 2 is the shape of the bottom 30 of the inner sleeve 3 adapted so that in the fully lowered state no Gap remains. The bottom 31 and the underside 30 are preferably flat, but can also e.g. be spherically curved. If the bottom 30 flat on the bottom 31 rests, the top detent groove 9 comes with the sealing lip 5 in Intervention. That is, the stroke of the bottom 30 corresponds to the distance of the Sealing groove 8 to the top detent groove 9.

Die Haltekräfte zwischen der äußeren Hülse 2 und der inneren Hülse 3 sind größer als die Haltekräfte des Micropinsels 1 in der inneren Hülse 3. Damit ist sichergestellt, daß bei einem Abziehen des Micropinsels 1 die innere Hülse nicht wieder nach oben gezogen wird.The holding forces between the outer sleeve 2 and the inner sleeve 3 are is greater than the holding forces of the micro brush 1 in the inner sleeve 3 ensured that when the micro brush 1 is removed, the inner sleeve is not pulled up again.

Die innere Hülse 3 spannt eine zweite Kammer 13 auf, die mit einer zweiten Flüssigkeit 16 gefüllt sein kann. Somit lassen sich zwei Kammern 12, 13 bilden, die eine Zweikomponenten-Lösung aufnehmen. Die erste Kammer 12 läßt sich im wesentlichen mit einem kleinen Restluftanteil auffüllen. Um die Restluft zu entfernen, kann die innere Hülse 3 vor Verschluß mit dem Micropinsel 1 in eine entsprechende Position abgesenkt werden. Ebenso ist es möglich, die Ampulle auf dem Kopf stehend zu füllen und den Standfuß 14 nach dem Befüllen anzuschweißen.The inner sleeve 3 spans a second chamber 13 with a second Liquid 16 can be filled. Two chambers 12, 13 can thus be formed, that incorporate a two-component solution. The first chamber 12 can be essentially fill up with a small amount of residual air. To the remaining air remove, the inner sleeve 3 before sealing with the micro brush 1 in a corresponding position can be lowered. It is also possible to use the ampoule upside down and fill the stand 14 after filling to weld.

An dem Kopfteil 28 des Micropinsels 1 ist eine Spitze 10 ausgebildet, die nach Fig.1 eine Beflockung 11 aufweist. Die Spitze 10 reicht im wesentlichen bis zu dem Bodenbereich der zweiten Kammer 13. Anstelle der Beflockung 11 können auch Pinselhaare vorgesehen sein. Die Spitze 10 kann auch direkt auf den Boden der zweiten Kammer 13 drücken, wenn die innere Hülse 3 abgesenkt werden soll. Bevorzugt ist jedoch an dem Micropinsel 1 eine Auflageschulter 4 vorgesehen, die sich z.B. an einem Absatz in der Wandung der inneren Hülse 3 abstützt. Somit laßt sich die innere Hülse 3 auch mit einem Micropinsel 1 absenken, der Pinselhaare aufweist.A tip 10 is formed on the head part 28 of the micro brush 1, which follows 1 has flocking 11. The tip 10 extends up to the bottom area of the second chamber 13. Instead of the flocking 11 can brush hairs may also be provided. The tip 10 can also directly on the Press the bottom of the second chamber 13 when the inner sleeve 3 is lowered shall be. However, a support shoulder 4 is preferred on the micro brush 1 provided, e.g. on a shoulder in the wall of the inner sleeve 3 supports. Thus, the inner sleeve 3 can also be used with a micro brush 1 lower, which has brush hair.

Wesentlich ist nun für den Absenkvorgang der inneren Hülse 3, daß Mittel vorgesehen sind, die ein Überströmen der Flüssigkeit 17 aus der ersten Kammer 12 in die zweite Kammer 13 der inneren Hülse 3 erlauben. Hierzu weist die Wandung der inneren Hülse 3 radiale Bohrungen 15 auf, die im Bodenbereich der Hülse 3 angeordnet sind. Je nach der Viskosität der Flüssigkeit 17 können eine oder mehrere Bohrungen 15 vorgesehen sein. Die Bohrungen 15, von der in Fig. 1 nur eine erkennbar ist, sind auf die innere Wandung der äußeren Hülse 2 gerichtet. Folglich dichtet die Wandung der äußeren Hülse 2 die Bohrungen 15 in der Wandung der inneren Hülse 3 ab.It is essential for the lowering process of the inner sleeve 3 that means are provided which overflow the liquid 17 from the first Allow chamber 12 in the second chamber 13 of the inner sleeve 3. For this has the wall of the inner sleeve 3 radial bores 15 which in Bottom region of the sleeve 3 are arranged. Depending on the viscosity of the Liquid 17 can be provided with one or more bores 15. The Bores 15, of which only one can be seen in Fig. 1, are on the inner Wall of the outer sleeve 2 directed. Consequently, the wall seals the outer sleeve 2 from the holes 15 in the wall of the inner sleeve 3.

Bei der Abwärtsbewegung der inneren Hülse 3 zwängt sich die Flüssigkeit 17 zwischen der inneren Hülse 3 und der inneren Wandung der äußeren Hülse 2 zu der Bohrung 15 und kann so in die zweite Kammer 13 überströmen. Damit die Wandungen der aufeinander liegenden Hülsen 2, 3 abheben können, besteht die Ampulle aus federelastischem Material.When the inner sleeve 3 moves downward, the liquid 17 is forced between the inner sleeve 3 and the inner wall of the outer sleeve 2 to the bore 15 and can thus flow into the second chamber 13. In order to the walls of the sleeves 2, 3 lying on top of each other can lift off, the ampoule is made of resilient material.

Weiter ist wesentlich, daß die Bildung eines Wandspaltes zwischen den Hülsen 2, 3 durch die Abdichtung aus der ringförmigen Dichtlippe 7 und der Dichtnut 8 unterstützt wird. Hierzu ist wichtig, daß die Dichtlippe 7 oberhalb der Kammer 12 bzw. des Flüssigkeitsspiegels der Flüssigkeit 17 angeordnet ist. Mit der Abwärtsbewegung der inneren Hülse 3 verläßt die Dichtlippe 7 die Dichtnut 8. Die Dichtlippe 7 kommt auf der äußeren Wandung der inneren Hülse 3 zum Gleiten. Wegen des nunmehr engeren Durchmessers preßt die innere Hülse 3 die Wandung der äußeren Hülse 2 in Richtung der Pfeile x nach außen bzw. die Wandung der inneren Hülse 3 wird nach innen gedrückt. Funktionell dient die Abdichtung aus der Dichtlippe 7 und der Dichtnut 8 zusätzlich dazu, bei der Abwärtsbewegung der inneren Hülse 3 den Wandungsspalt zu erhöhen, damit die Flüssigkeit 17 leicht überströmen kann. Dabei ist es unbeachtlich, ob die Dichtlippe 7 an der Hülse 2 oder der Hülse 3 ausgebildet ist, um die Spreizwirkung in Richtung der Pfeile x zu bewirken.It is also essential that the formation of a wall gap between the sleeves 2, 3 through the sealing of the annular sealing lip 7 and the sealing groove 8 is supported. For this it is important that the sealing lip 7 above the chamber 12 or the liquid level of the liquid 17 is arranged. With the Downward movement of the inner sleeve 3, the sealing lip 7 leaves the sealing groove 8. The sealing lip 7 comes to the outer wall of the inner sleeve 3 Slide. Because of the now narrower diameter, the inner sleeve 3 presses the wall of the outer sleeve 2 in the direction of the arrows x to the outside or the wall of the inner sleeve 3 is pressed inwards. Functionally serves the seal from the sealing lip 7 and the sealing groove 8 in addition to the Downward movement of the inner sleeve 3 to increase the wall gap so that can easily flow over the liquid 17. It is irrelevant whether the Sealing lip 7 is formed on the sleeve 2 or the sleeve 3 to the To cause spreading effect in the direction of arrows x.

Bevorzugt ist an der äußeren Wandung der inneren Hülse 3 ein Sammelkanal 18 vorgesehen, damit die Flüssigkeit schneller zu den Bohrungen 15 findet und sich kein zu hoher Druck bei dem Umströmvorgang der Flüssigkeit 17 zwischen den Wandungen aufbauen kann. Somit wird weiter vermieden, daß die äußere Hülse 2 platzen kann.A collecting duct is preferred on the outer wall of the inner sleeve 3 18 provided so that the liquid finds the holes 15 faster and there is no excessive pressure in the flow around the liquid 17 between can build up the walls. This further prevents the outer Sleeve 2 can burst.

Vorzugsweise umläuft der Sammelkanal 18 unter Verbindung der Bohrungen 15 die äußere Wandung der inneren Hülse 3 als wellenförmiger Kurvenzug so, daß die Bohrungen 15 in den Wellentälern liegen. Da die einzelnen Abschnitte des Sammelkanals 18 schiefe Ebenen bilden, ist sichergestellt, daß alle restlichen Teile der Flüssigkeit 17 in die zweite Kammer 13 abfließen und keine Restbestände in dem Sammelkanal 18 verbleiben. Im Zusammenwirken mit den zusätzlichen Rastnuten 9, die in bestimmten Höhenlagen angeordnet sind, lassen sich Anteile der Flüssigkeit 17 portionsweise in die Kammer 13 überführen. D.h., das Volumen der Kammer 12 läßt sich stufenweise verkleinern. Dabei verbleibt der Rest der Flüssigkeit 17 in der Kammer 12 weiterhin gut verschlossen.The collecting duct 18 preferably rotates by connecting the bores 15 the outer wall of the inner sleeve 3 as a wavy curve, that the holes 15 are in the troughs. Because the individual sections of the collecting channel form 18 inclined planes, it is ensured that all remaining parts of the liquid 17 flow into the second chamber 13 and none Remaining stocks remain in the collecting channel 18. In cooperation with the additional locking grooves 9, which are arranged at certain altitudes, portions of the liquid 17 can be added to the chamber 13 in portions convict. That is, the volume of the chamber 12 can be gradually downsize. The rest of the liquid 17 remains in the chamber 12 still well closed.

Weiter zeigt Fig. 1 eine Verschweißung 21 im oberen Bereich der Hülsen 2, 3. Ebenso ein umlaufende Sollbruchstelle 19 an der äußeren Hülse 2 und eine umlaufende Sollbruchstelle 20 an der inneren Hülse 3. Weiter ist ein Führungskanal 23 in der äußeren Hülse 2 und eine Nase 22 an der äußeren Wandung der inneren Hülse 3 vorgesehen. Der Führungskanal 23 weist eine L-Form auf, wobei ein ringförmiger Abschnitt die Achse y umkreist und ein geradliniger Abschnitt sich parallel zu der Achse y erstreckt. In Fig. 1 ist im wesentlichen nur der geradlinige Abschnitt erkennbar. Die Nase 22 ist an den Führungskanal 23 angepaßt. 1 shows a weld 21 in the upper region of the sleeves 2, 3. Likewise, a circumferential predetermined breaking point 19 on the outer sleeve 2 and one circumferential predetermined breaking point 20 on the inner sleeve 3. Next is a Guide channel 23 in the outer sleeve 2 and a nose 22 on the outer Wall of the inner sleeve 3 is provided. The guide channel 23 has an L shape with an annular portion encircling axis y and a rectilinear section extends parallel to the axis y. In Fig. 1 is in essentially only the rectilinear section is recognizable. The nose 22 is on the Guide channel 23 adapted.

Fig. 2 zeigt einen Schnitt durch den Bereich des Führungskanals 23 und die zylindrischen Wandungen der Hülsen 2, 3, die konzentrisch um den Micropinsel 1 angeordnet sind. Die Sollbruchstellen 19, 20 sowie die Nase 22 und der Führungskanal 23 bilden eine Kindersicherung. In der in Fig. 2 gezeigten Stellung liegt die Nase 22 auf dem ringförmigen Abschnitt der L-Form des Führungskanals 23 auf. Der ringförmige Abschnitt bildet gleichzeitig eine Geleitfläche 29 für die Nase 22. Ein Absenken der Hülse 3 in der gezeigten Position ist nicht möglich. FIG. 2 shows a section through the region of the guide channel 23 and the cylindrical walls of the sleeves 2, 3, which are arranged concentrically around the micro brush 1. The predetermined breaking points 19, 20 and the nose 22 and the guide channel 23 form a child lock. In the position shown in FIG. 2, the nose 22 rests on the annular section of the L-shape of the guide channel 23. The annular section simultaneously forms a guide surface 29 for the nose 22. A lowering of the sleeve 3 in the position shown is not possible.

Zum Absenken muß die nach Fig. 2 die äußere Hülse 2 im unteren Bereich gehalten und im oberen Bereich im Uhrzeigersinn gedreht werden. Dabei reißt die Sollbruchstelle 19 auf und die Nase 22 wird gleitend auf der Gleitfläche 29 zu dem geradlinigen Abschnitt des Führungskanals 23 geführt. Anschließend ist die Hülse 3 absenkbar und die Nase 22 gleitet in dem geradlinigen Abschnitt des Führungskanals 23. Dabei reißt die zweite Sollbruchstelle 20 auf.2, the outer sleeve 2 in the lower region held and rotated clockwise in the upper area. It tears the predetermined breaking point 19 and the nose 22 becomes sliding on the sliding surface 29 led to the rectilinear section of the guide channel 23. Subsequently the sleeve 3 can be lowered and the nose 22 slides in the straight section of the guide channel 23. The second predetermined breaking point 20 tears open.

Folglich wirken die Gleitfläche 29 und die Sollbruchstelle 19 in einer ersten Stufe zusammen, ein Absenken der Hülse 3 zu unterbinden. In einem zweiten Sicherungsschritt wirken die Verschweißung 21 und die Sollbruchstelle 20 zusammen, eine Absenken der Hülse 3 zu unterbinden, obwohl sich die Nase 22 über dem geraden Abschnitt des Führungskanals 23 befindet. Befinden sich eine weniger gefährliche Flüssigkeit 17 in der Kammer 12, kann man z.B. auf die Verschweißung 23 und die Sollbruchstelle 20 verzichten. In einer anderen Ausführungsform ist es gleichfalls möglich, den Führungskanal 23 umgekehrt anzuordnen, damit zuerst eine geradlinige Verschiebung und anschließend eine Drehbewegung erforderlich ist, um die Hülse 3 abzusenken.Consequently, the sliding surface 29 and the predetermined breaking point 19 act in a first Stage together to prevent the sleeve 3 from lowering. In a second The securing step acts on the weld 21 and the predetermined breaking point 20 together to prevent the sleeve 3 from lowering, even though the nose 22 is located above the straight section of the guide channel 23. Are located a less dangerous liquid 17 in the chamber 12, e.g. on do without the weld 23 and the predetermined breaking point 20. In another Embodiment, it is also possible to reverse the guide channel 23 to arrange, so first a linear shift and then a rotational movement is required to lower the sleeve 3.

Die oberen und abgetrennten Teile der Hülsen 2, 3 werden an dem Handgriff 26 in Richtung der Achse y verschoben und bilden einen Fingerschutz vor zurücklaufender Flüssigkeit, wenn der getränkte Micropinsel 1 entnommen wurde. The upper and separated parts of the sleeves 2, 3 are on the handle 26 shifted in the direction of the y axis and form a finger guard returning liquid when the soaked micro brush 1 is removed has been.

Mittels der Rastnuten 9 ist ein schrittweises Absenken und portionsweises Umfüllen der Flüssigkeit 17 in die Kammer 13 möglich. Fig. 3 zeigt, daß die Rastelemente, zu denen die Dichtlippe 7 und die Dichtnut 8 gehören als Sperriegel ausgebildet sein können und Hinterschneidungen aufweisen, so daß eine Rückbewegung der inneren Hülse 3 beim Abziehen des Micropinsel 1 vollkommen unterbunden wird.By means of the locking grooves 9 is a gradual lowering and portionwise Transferring the liquid 17 into the chamber 13 is possible. Fig. 3 shows that the Locking elements, which include the sealing lip 7 and the sealing groove 8 as Locking bolts can be formed and have undercuts so that a return movement of the inner sleeve 3 when the micro brush 1 is removed is completely prevented.
