Description

Die Erfindung betrifft einen Behälter.The invention relates to a container.

Der Behälter, auf welchen sich die Erfindung bezieht, dient spezifisch zur Bereitstellung eines Befestigungsmittels, bestehend aus einem aeroben Klebstoff und einem hydrophilen Aktivator.The container to which the invention relates specifically serves to provide a fastener consisting of an aerobic adhesive and a hydrophilic activator.

Ein derartiges Befestigungsmittel ist aus der WO 2009/156 013 A1 bekannt. Das dort beschriebene Befestigungsmittel besteht aus einer Mischung aus einem aeroben Klebstoff und einem hydrophilen Aktivator, wobei dem hydrophilen Aktivator dosiert Feuchtigkeit zugeführt ist. Der hydrophile Aktivator sorgt dafür, dass der aerobe Klebstoff in seinem gesamten Volumen aushärten kann.Such a fastener is from the WO 2009/156 013 A1 known. The fastening means described therein consists of a mixture of an aerobic adhesive and a hydrophilic activator, wherein the hydrophilic activator metered moisture is supplied. The hydrophilic activator ensures that the aerobic adhesive can cure in its entire volume.

Bei diesem System werden der aerobe Klebstoff und ein hydrophiler Stoff in separaten Behältern gelagert. Zur Bereitstellung des Befestigungsmittels wird aus dem ersten Behälter aerober Klebstoff in eine Schale gegeben. Dann wird aus dem zweiten Behälter der hydrophile Stoff in die Schale gegeben. Dann werden von einer Bedienperson mittels eines Spatels diese Komponenten miteinander vermischt, um so das Befestigungsmittel zu erhalten. Dabei ist der Spatel befeuchtet, so dass den Komponenten dosiert Feuchtigkeit zugeführt ist und das Befestigungsmittel aushärten kann. Dieses Befestigungsmittel wird dann dazu verwendet, einen Gegenstand auf einer Unterlage zu befestigen.In this system, the aerobic adhesive and a hydrophilic substance are stored in separate containers. To provide the fastener, aerobic adhesive is placed in a tray from the first container. Then, the hydrophilic substance is added to the dish from the second container. Then, by an operator by means of a spatula, these components are mixed together to obtain the fastener. In this case, the spatula is moistened, so that the components metered moisture is supplied and can harden the fastener. This fastener is then used to secure an article to a substrate.

Nachteilig hierbei ist, dass der Mischvorgang zum Durchmischen des aeroben Klebstoffs mit dem hydrophilen Stoff und die Zudosierung von Feuchtigkeit mehrere Arbeitsschritte umfasst, so dass die Bereitstellung des Befestigungsmittels relativ zeitaufwändig ist.The disadvantage here is that the mixing process for mixing the aerobic adhesive with the hydrophilic substance and the addition of moisture comprises several steps, so that the provision of the fastening means is relatively time consuming.

Ein weiterer Nachteil dieses Systems besteht darin, dass eine genaue, reproduzierbare Vorgabe eines Mischungsverhältnisses von aerobem Klebstoff und hydrophilem Stoff nicht oder nur mit hohem Aufwand möglich ist. Die Bedienperson müsste hierzu exakt abgemessene Mengen an aerobem Klebstoff aus dem ersten Behälter und weiterhin exakt abgemessene Mengen an hydrophilem Stoff aus dem zweiten Behälter ausführen, was ohne zusätzliche Messmittel nahezu unmöglich ist.Another disadvantage of this system is that an exact, reproducible specification of a mixing ratio of aerobic adhesive and hydrophilic substance is not possible or only with great effort. For this purpose, the operator would have to carry out exactly measured amounts of aerobic adhesive from the first container and furthermore exactly measured amounts of hydrophilic substance from the second container, which is almost impossible without additional measuring means.

Vielmehr sind die Mengen an aerobem Klebstoff und hydrophilem Stoff, die aus den beiden Behältern entnommen werden, typischerweise durch ein Abschätzen der Bedienperson mit erheblichen Ungenauigkeiten behaftet, so dass keine reproduzierbare Vorgabe eines bestimmten Mischungsbehältnisses möglich ist. Damit aber weist auch das so bereitgestellte Befestigungsmittel keine definierten Eigenschaften, insbesondere hinsichtlich des Aushärtungsprozesses und seiner Hafteigenschaften, auf.Rather, the amounts of aerobic adhesive and hydrophilic substance that are removed from the two containers, typically by estimating the operator with considerable inaccuracies, so that no reproducible specification of a particular mixing container is possible. However, the fastening means thus provided does not have any defined properties, in particular with regard to the curing process and its adhesive properties.

Der Erfindung liegt die Aufgabe zugrunde, einen Behälter der eingangs genannten Art so auszubilden, dass eine Bereitstellung eines Befestigungsmittels mit reproduzierbaren Eigenschafen ermöglicht wird.The invention has the object of providing a container of the type mentioned in such a way that a provision of a fastening means with reproducible properties is made possible.

Zur Lösung dieser Aufgabe sind die Merkmale des Anspruchs 1 vorgesehen. Vorteilhafte Ausführungsformen und zweckmäßige Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.To solve this problem, the features of claim 1 are provided. Advantageous embodiments and expedient developments of the invention are described in the dependent claims.

Die Erfindung betrifft einen Behälter mit zwei in dessen Längsrichtung verlaufenden, durch wenigstens eine Trennwand getrennten Innenkammern. In einer Innenkammer ist ein aerober Klebstoff gelagert. In der anderen Innenkammer ist ein hydrophiler, gelartiger Aktivator gelagert, wobei am vorderen Ende des Behälters eine Mischeinheit fixierbar ist. Über ein Fördermittel wird aerober Klebstoff aus der ersten Innenkammer und hydrophiler Aktivator aus der zweiten Innenkammer in einem vorgegebenen Mischungsverhältnis der Mischeinheit zugeführt und dort durchmischt. Diese Mischung wird über eine Auslassöffnung der Mischeinheit ausgeführt.The invention relates to a container with two extending in the longitudinal direction, separated by at least one partition inner chambers. An aerobic adhesive is stored in an inner chamber. In the other inner chamber, a hydrophilic gel-like activator is mounted, wherein at the front end of the container a mixing unit is fixable. Via a conveyor aerobic adhesive from the first inner chamber and hydrophilic activator from the second inner chamber in a predetermined mixing ratio of the mixing unit is supplied and mixed there. This mixture is carried out via an outlet opening of the mixing unit.

Das so gebildete Befestigungsmittel kann unmittelbar zur Fixierung zweier beliebig geformter Gegenstände verwendet werden.With the container according to the invention, a mounting set is provided, by means of which in a single operation, a mixture of an aerobic adhesive and a hydrophilic activator is automatically generated. The fastening means formed in this way can be used directly for fixing two arbitrarily shaped objects.

Ein wesentlicher Aspekt der Erfindung besteht darin, dass der aerobe Klebstoff und der hydrophile Aktivator in separaten Innenkammern des Behälters vollkommen getrennt voneinander gelagert werden. Dabei liegen der aerobe Klebstoff und der hydrophile Aktivator jeweils in fließfähiger Form vor, da der aerobe Klebstoff in der ersten Innenkammer in nicht ausgehärteter Form vorliegt, und in der zweiten Innenkammer ein gelförmiger hydrophiler Aktivator gelagert ist.An essential aspect of the invention is that the aerobic adhesive and the hydrophilic activator are stored in separate inner chambers of the container completely separate from each other. The aerobic adhesive and the hydrophilic activator are each in flowable form, since the aerobic adhesive is present in the first inner chamber in uncured form, and in the second inner chamber, a gel-shaped hydrophilic activator is mounted.

Um die in den Innenkammern gelagerten Komponenten miteinander zu mischen, braucht eine Bedienperson lediglich ein Fördermittel am hinteren Ende zu betätigen. Durch das Fördermittel werden insbesondere durch Erzeugen eines mechanischen Drucks sowohl der in der ersten Innenkammer gelagerte aerobe Klebstoff als auch der in der zweiten Innenkammer gelagerte hydrophile Aktivator der Mischeinheit zugeführt. In der Mischeinheit werden der aerobe Klebstoff und der hydrophile Aktivator selbsttätig gemischt, wobei vorteilhaft die Mischeinheit so ausgebildet ist, dass eine vollständige Durchmischung des aeroben Klebstoffs und des hydrophilen Aktivators erfolgt. Das so gebildete Gemisch wird über die Auslassöffnung der Mischeinheit ausgeführt und steht dann sofort als gebrauchsfertiges Befestigungsmittel zur Verfügung, mit dem zwei Gegenstände miteinander verbunden werden können.In order to mix the components stored in the inner chambers, an operator only needs to operate a conveyor at the rear end. By means of the conveying means, in particular by generating a mechanical pressure, both the aerobic adhesive stored in the first inner chamber and the hydrophilic activator mounted in the second inner chamber are fed to the mixing unit. In the mixing unit, the aerobic adhesive and the hydrophilic activator are mixed automatically, wherein advantageously the mixing unit is designed so that a complete mixing of the aerobic adhesive and the hydrophilic activator takes place. The mixture thus formed is carried out via the outlet opening of the mixing unit and is then immediately available as a ready-to-use fastener with which two objects can be connected to one another.

Wesentlich hierbei ist, dass der Behälter mit seinen Komponenten, insbesondere die Ausbildung der Innenkammern und des Fördermittels gewährleisten, dass bei Betätigen des Fördermittels stets aerober Klebstoff und hydrophiler Aktivator in demselben Mischungsverhältnis dieser Mischeinheit zugeführt wird. Damit wird allein durch den Behälter ein reproduzierbares, ideales Mischungsverhältnis vorgegeben, das ein vollständiges Aushärten des aeroben Klebstoffs durch die Zugabe einer dosierten Menge an hydrophilem Aktivator garantiert. Damit werden ideale und reproduzierbare Hafteigenschaften des aus aerobem Klebstoff und hydrophilem Aktivator bestehenden Befestigungsmittels erhalten.It is essential here that the container with its components, in particular the formation of the inner chambers and the conveying means, ensures that when the conveyor is actuated, aerobic adhesive and hydrophilic activator are always supplied in the same mixing ratio to this mixing unit. In order to a reproducible, ideal mixing ratio is predetermined solely by the container, which guarantees complete curing of the aerobic adhesive by the addition of a metered amount of hydrophilic activator. This provides ideal and reproducible adhesive properties of the fastening agent consisting of aerobic adhesive and hydrophilic activator.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist der aerobe Klebstoff von silanen Polymeren oder von Polyurethan gebildet.According to an advantageous embodiment of the invention, the aerobic adhesive is formed by silane polymers or by polyurethane.

Weiter vorteilhaft ist der hydrophile Aktivator von Baumwolle, Cellulose, einem Faserverbundwerkstoff, einem Salz, einem Mineral, einem Harz, Glycerin oder Propylenglykol gebildet.Further advantageously, the hydrophilic activator of cotton, cellulose, a fiber composite material, a salt, a mineral, a resin, glycerol or propylene glycol is formed.

Da der hydrophile Aktivator gelförmig in der Innenkammer vorliegt, kann der hydrophile Aktivator vorteilhaft Feuchtigkeit, insbesondere Wasser oder Isopropanol enthalten.Since the hydrophilic activator is in the form of a gel in the inner chamber, the hydrophilic activator may advantageously contain moisture, in particular water or isopropanol.

Die Innenkammern des Behälters bilden vorteilhaft kanalförmige Strukturen aus, die sich im Wesentlichen über die gesamte Länge des Behälters erstrecken.The inner chambers of the container advantageously form channel-shaped structures which extend substantially over the entire length of the container.

Gemäß einer ersten konstruktiven Variante sind die Innenkammern nebeneinander liegend angeordnet.According to a first constructive variant, the inner chambers are arranged lying side by side.

Alternativ ist eine zentrale erste Innenkammer vorgesehen, welche von der zweiten Innenkammer umschlossen ist.Alternatively, a central first inner chamber is provided, which is enclosed by the second inner chamber.

Gemäß einer ersten vorteilhaften Ausgestaltung der Erfindung ist der Behälter in Form einer Tube ausgebildet, deren Außenwand flexibel ist.According to a first advantageous embodiment of the invention, the container is designed in the form of a tube whose outer wall is flexible.

In diesem Fall ist das Fördermittel von einem Tubenschlüssel am hinteren Ende der Tube gebildet.In this case, the conveyor is formed by a tube key at the rear end of the tube.

Mit dem Tubenschlüssel kann das hintere Ende der Tube in bekannter Weise aufgerollt werden, wodurch ein gleichförmiger Druck auf den aeroben Klebstoff in der ersten Innenkammer und den hydrophilen Aktivator in der zweiten Innenkammer erzeugt wird, der dazu führt, dass aerober Klebstoff und hydrophiler Aktivator in einem vorgegebenen Mischungsverhältnis der Mischeinheit zugeführt werden.With the tube key, the rear end of the tube can be rolled up in a known manner, creating a uniform pressure on the aerobic adhesive in the first inner chamber and the hydrophilic activator in the second inner chamber, which causes the aerobic adhesive and hydrophilic activator in one predetermined mixing ratio of the mixing unit are supplied.

Gemäß einer zweiten vorteilhaften Ausgestaltung der Erfindung ist der Behälter in Form einer Kartusche ausgebildet.According to a second advantageous embodiment of the invention, the container is designed in the form of a cartridge.

In diesem ist das Fördermittel von wenigstens einem Kolben am hinteren Ende der Kartusche gebildet.In this, the funding is formed by at least one piston at the rear end of the cartridge.

Mit dem oder den Kolben wird sowohl auf den aeroben Klebstoff in der ersten Innenkammer als auch auf den hydrophilen Aktivator in der zweiten Innenkammer ein definierter Druck ausgeübt, der dazu führt, dass aerober Klebstoff und hydrophiler Aktivator in einem vorgegebenen Mischungsverhältnis der Mischeinheit zugeführt werden.With the piston or pistons, a defined pressure is exerted both on the aerobic adhesive in the first inner chamber and on the hydrophilic activator in the second inner chamber, which results in that aerobic adhesive and hydrophilic activator are supplied in a predetermined mixing ratio of the mixing unit.

Gemäß einer vorteilhaften Ausgestaltung ist die Mischeinheit ein Statik-Mischer, welcher ein Mischrohr und eine Mischwendel aufweist.According to an advantageous embodiment, the mixing unit is a static mixer, which has a mixing tube and a mixing coil.

Mit diesem Statik-Mischer kann auf einfache Weise eine vollständige Durchmischung des aeroben Klebstoffs und des hydrophilen Aktivators, die aus den Innenkammern diesem zugeführt werden, durchgeführt werden. Die vollständige Durchmischung wird dabei durch eine hinreichend lange Mischwendel erreicht, da die anfangs getrennten Komponenten, das heißt der aerobe Klebstoff und der hydrophile Aktivator mit jeder Umdrehung der Mischwendel weiter vermischt werden.With this static mixer can be easily carried out a complete mixing of the aerobic adhesive and the hydrophilic activator, which are supplied from the inner chambers this. The complete mixing is achieved by a sufficiently long mixing helix, since the initially separate components, that is, the aerobic adhesive and the hydrophilic activator with each revolution of the mixing helix are further mixed.

Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist am vorderen Ende des Behälters ein Anschlusssegment vorgesehen, an welchem die Mischeinheit reversibel lösbar befestigbar ist.According to a further advantageous embodiment of the invention, a connection segment is provided at the front end of the container, to which the mixing unit is reversibly releasably fastened.

Insbesondere weist das Anschlusssegment ein Gehäuse auf, so dass die Mischeinheit an diesem aufschraubbar ist.In particular, the connection segment has a housing, so that the mixing unit can be screwed onto it.

Wenn durch das Betätigen des Fördermittels aerober Klebstoff und hydrophiler Aktivator aus den Innenkammern der Mischeinheit zum Mischen dieser Komponenten zugeführt werden, wird zwar der größte Teil der in der Mischeinheit erzeugten Mischung über deren Auslassöffnung ausgeführt. Jedoch verbleiben typischerweise noch Reste der Mischung in der Mischeinheit und härten dort aus, so dass dann die Mischeinheit unbrauchbar wird. Um mehrmals aus dem Behälter aeroben Klebstoff und hydrophilen Aktivator zu fördern und zur Erzeugung des Befestigungsmittels nutzen zu können, kann eine Mischeinheit nach Gebrauch vom Behälter abgenommen und dann durch eine neue Mischeinheit ersetzt werden.When aerobic adhesive and hydrophilic activator are supplied from the inner chambers of the mixing unit to mix these components by the actuation of the conveying means, most of the mixture produced in the mixing unit is carried out via its outlet opening. However, typically remains of the mixture in the mixing unit and harden out there, so that then the mixing unit is unusable. In order to be able to pump aerobic adhesive and hydrophilic activator several times from the container and use it to produce the fastening means, a mixing unit can be removed from the container after use and then replaced by a new mixing unit.

Figur 1 zeigt ein erstes Ausführungsbeispiel des erfindungsgemäßen Behälters in Form einer Tube 1. Die Tube 1 umfasst in bekannter Weise einen Grundkörper mit einem flexiblen Außenrand 2, die beispielsweise aus einem reversibel verformbaren Kunststoff besteht. Am vorderen Ende der Tube 1 befindet sich ein Anschlusssegment 3, das eine im Wesentlichen hohlzylindrische Form aufweist und aus einem starren, biegefesten Material, insbesondere aus einem Kunststoff besteht. Auf der äußeren Mantelfläche befindet sich ein Außengewinde 4. Am hinteren Ende der Tube 1 befindet sich ein Tubenschlüssel 5. FIG. 1 shows a first embodiment of the container according to the invention in the form of a tube 1. The tube 1 comprises in a known manner a base body with a flexible outer edge 2, which consists for example of a reversibly deformable plastic. At the front end of the tube 1 is a Terminal segment 3, which has a substantially hollow cylindrical shape and consists of a rigid, bending-resistant material, in particular of a plastic. On the outer lateral surface is an external thread 4. At the rear end of the tube 1 is a tube key. 5

Erfindungsgemäß ist der Innenraum der Tube 1 in zwei Innenkammern 6, 7 unterteilt. Figur 2 zeigt eine erste Ausführungsform, bei welcher die beiden Innenkammern 6, 7 nebeneinanderliegend angeordnet sind. Figur 3 zeigt eine zweite Ausführungsform mit zwei koaxial verlaufenden Innenkammern 6, 7, das heißt eine erste Innenkammer 6 umgibt eine zweite zentrale Innenkammer 7.According to the interior of the tube 1 is divided into two inner chambers 6, 7. FIG. 2 shows a first embodiment in which the two inner chambers 6, 7 are arranged side by side. FIG. 3 shows a second embodiment with two coaxial inner chambers 6, 7, that is, a first inner chamber 6 surrounds a second central inner chamber. 7

Bei beiden Ausführungsformen verlaufen die Innenkammern 6, 7 in Längsrichtung der Tube 1 parallel zueinander. Dabei sind die Innenkammern 6, 7 durch Wandungen 8 vollkommen getrennt voneinander. Jede Innenkammer 6, 7 erstreckt sich über die gesamte Länge, wobei insbesondere die Innenkammern 6, 7 im Bereich des Anschlusssegments 3 Ausmündungsbereiche 6a, 7a bilden, die durch die Wandungen 8 getrennt sind. Damit werden in den Innenkammern 6, 7 mit ihren Ausmündungsbereichen 6a, 7a unterschiedliche Stoffe völlig getrennt voneinander gelagert.In both embodiments, the inner chambers 6, 7 extend in the longitudinal direction of the tube 1 parallel to each other. The inner chambers 6, 7 are completely separated from each other by walls 8. Each inner chamber 6, 7 extends over the entire length, wherein in particular the inner chambers 6, 7 in the region of the connection segment 3 form Ausmündungsbereiche 6a, 7a, which are separated by the walls 8. Thus, different substances are stored completely separate from each other in the inner chambers 6, 7 with their discharge areas 6a, 7a.

Erfindungsgemäß ist in der ersten Innenkammer 6 ein aerober Klebstoff gelagert. In der zweiten Innenkammer 7 ist ein hydrophiler Aktivator gelagert.According to the invention, an aerobic adhesive is mounted in the first inner chamber 6. In the second inner chamber 7, a hydrophilic activator is mounted.

Der aerobe Klebstoff ist von einem silanen Polymer oder von Polyurethan gebildet. Der aerobe Klebstoff liegt in der ersten Innenkammer 6 in nicht ausgehärteter Form und damit in fließfähiger Form vor.The aerobic adhesive is formed by a silane polymer or polyurethane. The aerobic adhesive is present in the first inner chamber 6 in uncured form and thus in flowable form.

In der zweiten Innenkammer 7 ist ein hydrophiler Aktivator gelagert, der generell einen Reaktionsbeschleuniger bildet, der das Aushärten des aeroben Klebstoffs beschleunigt, wenn der hydrophile Aktivator mit dem aeroben Klebstoff durchmischt wird.In the second inner chamber 7, a hydrophilic activator is supported, which generally forms a reaction accelerator, which accelerates the curing of the aerobic adhesive when the hydrophilic activator is mixed with the aerobic adhesive.

Der hydrophile Aktivator liegt in der zweiten Innenkammer 7 in gelartiger und damit in fließfähiger Form vor. Vorteilhaft ist der hydrophile Aktivator von Baumwolle, Cellulose, einem Faserverbundwerkstoff, einem Salz, einem Mineral, einem Harz, Glycerin oder Propylenglykol gebildet.The hydrophilic activator is in the second inner chamber 7 in gel-like and thus in flowable form. Advantageously, the hydrophilic activator of cotton, cellulose, a fiber composite material, a salt, a mineral, a resin, glycerol or propylene glycol is formed.

Insbesondere für den Fall, dass die Substanzen des hydrophilen Aktivators ursprünglich in fester Form vorliegen, ist dem hydrophilen Aktivator Feuchtigkeit, insbesondere Wasser oder Isopropanol beigemischt, so dass der hydrophile Aktivator in gelartiger Form vorliegt.In particular in the event that the substances of the hydrophilic activator are originally present in solid form, the hydrophilic activator is admixed with moisture, in particular water or isopropanol, so that the hydrophilic activator is in gelatinous form.

Um ein Befestigungsmittel bereitzustellen, mittels dessen zwei Gegenstände durch eine Klebeverbindung dauerhaft und fest verbunden werden, wird auf dem Anschlusssegment 3 eine Mischeinheit aufgesetzt. Eine derartige Mischeinheit in Form eines Statik-Mischers 9 zeigt Figur 4.To provide a fastener by means of which two objects are permanently and firmly connected by an adhesive bond, a mixing unit is placed on the connection segment 3. Such a mixing unit in the form of a static mixer 9 shows FIG. 4 ,

Der Statik-Mischer 9 umfasst ein Mischrohr 10 und eine im Mischrohr 10 gelagerte, sich in dessen Längsrichtung erstreckende Mischwendel 11. Im vorliegenden Fall weist die Mischwendel 11 vier in axialer Richtung aneinander anschließende Wendelsegmente auf. Generell kann auch eine andere, insbesondere größere Anzahl von Wandelsegmenten vorgesehen sein. Am hinteren Ende des Statik-Mischers 9 befindet sich ein Gewinde 12, das auf das Außengewinde 4 des Anschlusssegments des Behälters aufgeschraubt werden kann, wodurch eine reversibel lösbare Verbindung zwischen Behälter und Statik-Mischer 9 entsteht. Das vordere Ende des Statik-Mischers 9 ist in Form einer Spitze ausgebildet, an deren vorderem Rand eine Auslassöffnung 13 vorgesehen ist.The static mixer 9 comprises a mixing tube 10 and a mixing spiral 10 mounted in the mixing tube 10 and extending in its longitudinal direction. In the present case, the mixing spiral 11 has four spiral segments adjoining one another in the axial direction. In general, another, in particular larger number of change segments can be provided. At the rear end of the static mixer 9 is a thread 12 which can be screwed onto the external thread 4 of the terminal segment of the container, whereby a reversible detachable connection between the container and static mixer 9 is formed. The front end of the static mixer 9 is in the form of a tip, at the front edge of which an outlet opening 13 is provided.

Zur Bereitstellung des Befestigungsmittels wird der Tubenschlüssel 5 gedreht, das heißt allgemein das Fördermittel betätigt, wodurch vom hinteren Ende der Tube 1 aus ein Druck sowohl auf den aeroben Klebstoff in der ersten Innenkammer 6 als auch auf den hydrophilen Aktivator in der zweiten Innenkammer 7 ausgeübt wird. Durch diesen Druck werden aus den beiden Innenkammern 6, 7 sowohl aerober Klebstoff als auch hydrophiler Aktivator dem Statik-Mischer 9 zugeführt. Durch die Ausbildung des Fördermittels in Form des Tubenschlüssels 5, der einen gleichförmigen Druck auf den aeroben Klebstoff in der ersten Innenkammer 6 und den hydrophilen Aktivator in der zweiten Innenkammer 7 ausübt und durch die spezifische geometrische Ausbildung der Innenkammern 6, 7 ist gewährleistet, dass der aerobe Klebstoff und der hydrophile Klebstoff in einem definierten konstanten Mischungsverhältnis dem Statik-Mischer 9 zugeführt werden.To provide the fastener of the tube key 5 is rotated, that is generally actuated the conveyor, whereby from the rear end of the tube 1 of a pressure on both the aerobic adhesive in the first inner chamber 6 and on the hydrophilic activator in the second inner chamber 7 is applied , As a result of this pressure, both the aerobic adhesive and the hydrophilic activator are supplied to the static mixer 9 from the two inner chambers 6, 7. By the formation of the conveyor in the form of the tube key 5, which exerts a uniform pressure on the aerobic adhesive in the first inner chamber 6 and the hydrophilic activator in the second inner chamber 7 and by the specific geometric configuration of the inner chambers 6, 7 ensures that the aerobic adhesive and the hydrophilic adhesive in a defined constant mixing ratio to the static mixer 9 are supplied.

Im Statik-Mischer 9 werden der aerobe Klebstoff und der hydrophile Aktivator in Folge des vom Tubenschlüssel 5 ausgeübten Drucks nacheinander durch die einzelnen Wendelsegmente der Mischwendel 11 geführt. Von einem Wendelsegment zum nächsten erfolgt eine immer stärkere Durchmischung der beiden Komponenten. Die Anzahl der Wendelsegmente ist so gewählt, dass am Ende der Mischwendel 11 der aerobe Klebstoff und der hydrophile Aktivator vollständig durchmischt sind. Das so gebildete Befestigungsmittel wird dann über die Auslassöffnung 13 aus dem Statik-Mischer 9 ausgeleitet und kann dann zur Fixierung zweier Gegenstände verwendet werden.In the static mixer 9, the aerobic adhesive and the hydrophilic activator are successively guided through the individual helical segments of the mixing helix 11 as a result of the pressure exerted by the tube key 5. From one spiral segment to the next there is an ever greater mixing of the two components. The number of helical segments is chosen so that at the end of the mixing helix 11 of the aerobic adhesive and the hydrophilic activator are completely mixed. The fastener thus formed is then discharged via the outlet opening 13 from the static mixer 9 and can then be used for fixing two objects.

Nach Gebrauch des Statik-Mischers 9 wird dieser wieder vom Behälter abgeschraubt. Sobald der Behälter von neuem zur Bereitstellung des Befestigungsmittels benötigt wird, wird ein neuer Statik-Mischer 9 auf das Anschlusssegment des Behälters aufgeschraubt.After use of the static mixer 9 this is unscrewed from the container again. Once the container is needed anew to provide the fastener, a new static mixer 9 is screwed onto the terminal segment of the container.

Figur 5 zeigt ein zweites Ausführungsbeispiel des Behälters in Form einer Kartusche 14. Die Kartusche 14 weist analog zur Ausführungsform der Figur 2 zwei konzentrische, durch eine Wandung 8 getrennte Innenkammern 6, 7 auf. Prinzipiell können auch nebeneinanderliegende Innenkammern 6, 7 vorgesehen sein. FIG. 5 shows a second embodiment of the container in the form of a cartridge 14. The cartridge 14 has analogous to the embodiment of FIG. 2 two concentric, separated by a wall 8 inner chambers 6, 7. In principle, adjacent inner chambers 6, 7 may be provided.

Analog zur Ausführungsform von Figur 1 ist am vorderen Ende der Kartusche 14 ein Anschlusssegment 3 mit einem Außengewinde 4 vorgesehen. Die Innenkammern 6, 7 erstrecken sich über die gesamte Länge der Kartusche 14 und sind mit ihren Ausmündungsbereichen 6a, 7a bis in den Innenraum des Anschlusssegments 3 geführt.Analogous to the embodiment of FIG. 1 At the front end of the cartridge 14, a connection segment 3 with an external thread 4 is provided. The inner chambers 6, 7 extend over the entire length of the cartridge 14 and are guided with their mouth areas 6a, 7a into the interior of the connection segment 3.

Am hinteren Ende der Kartusche 14 befinden sich Kolben 15a, 15b als Fördermittel. Durch ein nicht dargestelltes Betätigungsmittel wird mit dem ersten Kolben 15a ein Druck auf den in der ersten Innenkammer 6 gelagerten aeroben Klebstoff ausgeübt. Entsprechend wird dem zweiten Kolben 15b ein Druck auf den in der Innenkammer 7 gelagerten hydrophilen Aktivator ausgeübt. Vorzugsweise wird auf beide Komponenten der gleiche Druck ausgeübt. Der aerobe Klebstoff und der hydrophile Aktivator entsprechen hinsichtlich ihrer Ausbildung der Ausführungsform gemäß Figur 1.At the rear end of the cartridge 14 are pistons 15a, 15b as conveying means. By an actuating means, not shown, with the first piston 15a, a pressure on the stored in the first inner chamber 6 aerobic adhesive is exercised. Accordingly, the second piston 15b, a pressure on the bearing in the inner chamber 7 hydrophilic activator is exercised. Preferably, the same pressure is exerted on both components. The aerobic adhesive and the hydrophilic activator correspond to the embodiment according to their embodiment FIG. 1 ,

In weiterer Analogie zur Ausführungsform gemäß Figur 1 kann der Statik-Mischer 9 gemäß Figur 5 auf das Anschlusssegment 3 der Kartusche 14 aufgeschraubt werden. Dann wird durch Ausüben von Druck mit den Kolben 15a, 15b aerober Klebstoff aus der ersten Innenkammer 6 und hydrophiler Aktivator aus der zweiten Innenkammer 7 dem Statik-Mischer 9 zugeführt, wo die Durchmischung dieser Komponenten erfolgt. Das so gebildete Befestigungsmittel wird wieder über die Auslassöffnung 13 des Statik-Mischers 9 ausgeführt.In a further analogy to the embodiment according to FIG. 1 can the static mixer 9 according to FIG. 5 be screwed onto the connection segment 3 of the cartridge 14. Then, by applying pressure with the pistons 15a, 15b, aerobic adhesive from the first inner chamber 6 and hydrophilic activator from the second inner chamber 7 are fed to the static mixer 9, where the mixing of these components takes place. The fastening means thus formed is carried out again via the outlet opening 13 of the static mixer 9.
