Abstract

The new bag cartridges (1, 12) are intended for use in re-usable applicators. Not only are cartridges (1) for a single component possible, but also cartridges (12) for two components (e.g. two-component adhesives). The advantage of the new cartridge is that the packaging necessary for the filler or adhesive is reduced to the absolute minimum, viz: a thin sheet of highly tear-resistant plastic. The applicator nozzle (4) is directly bonded or welded to the cartridge. The nozzle can be hermetically sealed with a cap (5) to prevent the filler or adhesive in the nozzle from drying out, thus avoiding any need to clean out the nozzle before use. For components which must be mixed thoroughly together or which react readily with each other, there is a special (screw-on) mixer nozzle (15). For special applications, cartridges can be designed with a semicircular nozzle (23).

Die heute verwendeten Einwegkartuschen bestehen aus dickwandigen Kunst¬ stoffdosen. Deren Verwendung ist so stark gewachsen, dass von einem ech¬ ten Abfallproblem und Materialverschwendung gesprochen werden uss. Aus- serdem können die Spritzdüsen nicht verschlossen werden, so dass die Dichtmasse oder der Klebstoff bei Nichtgebrauch austrocknet. Zum Verarbeiten von zwei Komponenten müssen Spezialkittpistolen verwendet werden, die wiederum Spezialkartuschen benötigen.The disposable cartridges used today consist of thick-walled plastic cans. Their use has grown so much that there is talk of a real waste problem and wasted material. In addition, the spray nozzles cannot be closed, so that the sealant or adhesive dries out when not in use.

Bis heute gibt es nur für vereinzelte Kittauspresswerkzeuge dazu passende in sogenannte Folienumhüllungen abgepackte Dichtmassen oder Klebstoffe. Für die gängigsten Dauerkartuschen existiert nichts Vergleichbares, das auch im grossen Rahmen, das heisst im Do-it-yourself-Bereich, angewendet wird. Obwohl heute überall der Anteil an Verpackung reduziert wird und von Einwegverpackungen verlangt wird, dass sie so wenig Material wie nur möglich brauchen, werden bis heute relativ dickwandige Kunststoffdosen als Einwegkartuschen verwendet. Bei der Verarbeitung von zwei Komponenten müssen unhandliche Spezialkitt- pistolen verwendet werden. Es handelt sich um ein Werkzeug mehr, das angeschafft werden muss. Dabei kommt es vor, dass die Kartuschen und Werkzeuge untereinander nicht kompatibel sind; man braucht auch noch die passenden Spezialkartuschen, wenn man zum Beispiel Zweikomponentenkleber verarbeiten will.To date, there are only suitable sealants or adhesives packaged in so-called foil wrappers for isolated kit extrusion tools. There is nothing comparable for the most common permanent cartridges that is also used on a large scale, i.e. in the do-it-yourself area. Although the proportion of packaging is reduced everywhere today and disposable packaging is required to use as little material as possible, relatively thick-walled plastic cans are still used as disposable cartridges. Bulky special cement guns must be used when processing two components. It is one more tool that must be purchased. It happens that the cartridges and tools are not compatible with each other; You also need the right special cartridges if you want to process two-component adhesives, for example.
Mit den nachfolgend beschriebenen Folienkartuschen für eine oder zwei Komponenten wird das benötigte Verpackungsmaterial drastisch reduziert. Die Folienkartuschen werden in Dauerkartuschen eingesetzt. Ausserde wird durch die bereits aufgesetzte Spritzdüse das Handling sehr stark erleich¬ tert. Es zeigen:With the film cartridges for one or two components described below, the packaging material required is drastically reduced. The foil cartridges are used in permanent cartridges. In addition, handling is greatly facilitated by the spray nozzle already attached. Show it:

Die Folienkartusche 1 (Fig.1) besteht aus einem Schlauch 2 aus dünner, hochreissfester Kunststoffolie, der am Boden 3 einer Spritzdüse 4 ange¬ leimt oder angeschweisst ist. Der Boden 3 ist als eine Art Rondelle aus¬ gebildet, welche verhindert, dass die Folienkartusche beim Auspressen aus der Bohrung des Deckels der Dauerkartusche herausgedrückt wird. Die Masse der Kunststofffol e ist im Vergleich zur Masse der bisher verwendeten Ein¬ wegkartusche vernachlässigbar klein. Ferner werden die Spritzdüsen 3 erstmals mit einer hermetisch abdichtenden Verschlusskappe 5 versehen. Die Spritzdüse 4 weist eine rundumlaufende Rille 6 auf, in die ein innen an der Verschlusskappe 5 ausgeformter Dichtring 7 einrastet. Dabei ver¬ steht es sich von selbst, dass die Abmessungen der Rille 6 und des Dicht¬ ringes 7 so gewählt werden, dass die Verschlusskappe zum einen wirklich hermetisch abdichtet und zum anderen satt auf die Spritzdüse 4 aufge¬ steckt werden kann. Somit wird verhindert, dass bei Nichtgebrauch der in der Spritzdüse 3 verbleibende Kitt oder Klebstoff austrocknet. Das bedeu- tet wiederum Materialeinsparung, denn einmal ausgetrockneter Kitt oder Klebstoff ist verloren. Ausserdem entfällt das mühsame Reinigen verstopf¬ ter Düsen. Selbstverständlich besteht die Möglichkeit, die Verschlusskap¬ pe mit einer Art Bügel zu versehen, mit welchem sie unverlierbar mit der Spritzdüse verbunden ist. Dieses System wird zum Beispiel bei Verschlüs¬ sen von Oelkännchen aus Kunststoff verwendet. Der Durchmesser 8 und die Länge 9 der Folienkartusche 1 werden so gewählt, dass sie für die heute bereits üblichen Dauerkartuschen verwendet werden können. Diese Abmessun¬ gen können ohne weiteres modifiziert werden, wenn in Zukunft neue, noch zu entwickelnde Dauerkartuschen auf den Markt kommen sollten. Dasselbe gilt auch für den Schaftdurchmesser 10 der Spritzdüse, der so gewählt wird, dass diese ohne weiteres durch die Bohrung des abschraubbaren Dek- kels der Dauerkartuschen geführt werden kann. Es ist ersichtlich, dass wie bei den bisherigen Düsen der Einwegkartuschen die Spitze der Spritz¬ düse 4 weiter vorne oder weiter hinten abgeschnitten wird, je nachdem, ob ein dünner oder ein breiter Streifen ausgepresst werden soll. Die Folienkartusche ist auch mit einer Halbrunddüse 23 (Fig. 3) erhält¬ lich. Wie der Name schon sagt, formt diese Düse den austretenden Kitt¬ oder Klebstoffstreifen zu einem Dichtstreifen, dessen Querschnitt ein halber Kreisquerschnitt ist. Die Halbrunddüse 23 kann nun so in eine zu dichtende Fuge gelegt werden, dass wie in Fig. 3a gezeigt, eine mit den Oberfl chen des bearbeiteten Gegenstandes ebener Dichtstreifen entsteht. Dieses Verfahren ist vor allem für breitere Fugen geeignet. Das mühsame Glattstreichen der Kittfuge entfällt, was zum einen Zeit spart und zum anderen eine saubere Arbeit ermöglicht. Wird die Halbrunddüse um 180° gedreht angesetzt, so können damit hervorragend schmale Fugen, zum Bei¬ spiel Stossfugen von Schalungsblechen, abgedichtet werden; es entsteht dann, wie in Fig. 3b dargestellt, eine überlappende Abdichtung, die eben¬ falls nicht nachbearbeitet werden muss. Die Halbrunddüse ist ebenfalls mit einer entsprechend geformten hermetisch abdichtenden Verschlusskappe 5 versehen.The film cartridge 1 (FIG. 1) consists of a tube 2 made of thin, highly tear-resistant plastic film which is glued or welded to the bottom 3 of a spray nozzle 4. The bottom 3 is designed as a kind of rondelle, which prevents the film cartridge from being pressed out of the hole in the cover of the permanent cartridge when it is pressed out. The mass of the plastic film is negligibly small compared to the mass of the disposable cartridge used to date. Furthermore, the spray nozzles 3 are provided with a hermetically sealing cap 5 for the first time. The spray nozzle 4 has a circumferential groove 6, into which a sealing ring 7 formed on the inside of the sealing cap 5 engages. It goes without saying that the dimensions of the groove 6 and the sealing ring 7 are selected such that the sealing cap on the one hand really hermetically seals and on the other hand can be snugly fitted onto the spray nozzle 4. This prevents the putty or adhesive remaining in the spray nozzle 3 from drying out when not in use. That means Material savings, because once the putty or adhesive has dried out, it is lost. In addition, there is no laborious cleaning of clogged nozzles. Of course, there is the possibility of providing the closure cap with a type of clip with which it is captively connected to the spray nozzle. This system is used, for example, for sealing oil jugs made of plastic. The diameter 8 and the length 9 of the film cartridge 1 are chosen so that they can be used for the permanent cartridges which are already common today. These dimensions can be easily modified if new, still to be developed, permanent cartridges should come onto the market in the future. The same also applies to the shaft diameter 10 of the spray nozzle, which is selected so that it can be easily passed through the bore of the screw-on cover of the permanent cartridges. It can be seen that, as with the previous nozzles of the disposable cartridges, the tip of the spray nozzle 4 is cut further forward or further back, depending on whether a thin or a wide strip is to be pressed out. The film cartridge is also available with a semicircular nozzle 23 (FIG. 3). As the name suggests, this nozzle forms the emerging putty or adhesive strip into a sealing strip, the cross section of which is half a circular cross section. The semicircular nozzle 23 can now be placed in a joint to be sealed in such a way that, as shown in FIG. 3a, a sealing strip which is flat with the surfaces of the processed object is produced. This process is particularly suitable for wider joints. The tedious smoothing of the putty joint is no longer necessary, which on the one hand saves time and on the other hand enables clean work. If the semicircular nozzle is turned through 180 °, it can be used to seal extremely narrow joints, for example butt joints of formwork sheets; This results in an overlapping seal, as shown in FIG. 3b, which also does not have to be reworked. The semicircular nozzle is also provided with a correspondingly shaped hermetically sealing cap 5.
Nach dem Abfüllen der Folienkartusche 1 mit Kitt oder Klebstoff wird das Ende 11 zusammengeschnürt oder verschweisst. Mit der von der Folienkartusche 1 abgeleiteten Folienkartusche 12 für zwei Komponenten (Fig. 2) können die bis heute notwendigen Spezialkittpi- stolen ersetzt werden, da man in den meisten Fällen sowieso über eine Kittpistole mit Dauerkartusche verfügt, für welche die Folienkartusche 11 bestens geeignet ist. Dabei wird ein dünnerer innerer Folienschlauch 14 in den äusseren Folienschlauch 13 eingesetzt. Der innere Folienschlauch nimmt die zweite Komponente auf und ist, je nach Anteil dieser Komponen¬ te, von Fall zu Fall verschieden dick.After filling the film cartridge 1 with putty or adhesive, the end 11 is tied up or welded. With the foil cartridge 12 derived from the foil cartridge 1 for two components (FIG. 2), the special cement guns that have been necessary up to now can be replaced, since in most cases a cement gun with permanent cartridge is available anyway, for which the foil cartridge 11 is best suited . A thinner inner film tube 14 is inserted into the outer film tube 13. The inner film tube accommodates the second component and, depending on the proportion of these components, varies in thickness from case to case.
Je nach Art der verwendeten Komponenten kann es notwendig sein, eine Spe¬ zialspritzdüse 15 (Fig. 4) zu verwenden, welche die beiden Komponenten durchmischt. Diese wird auf das Aussengewinde 16 der runden Austrittsöff¬ nung 17 der ersten Komponente geschraubt. Dass die Mischspritzdüse 15 nicht ein Teil mit dem Boden 3 (Fig.!) bildet, hat seinen Grund darin, dass so auch Komponenten gemischt werden können, die schon bei geringfü¬ gigen Mengen miteinander stark reagieren. Wenn nun einfach eine Ver¬ schlusskappe auf die Düse gesteckt würde, so wäre nicht gewährleistet, dass ein Aushärten des Zweikomponentenkittes oder Zweikomponentenklebers unterbunden ist. Um das sicherzustellen, müssen die beiden Komponenten voneinander abgeschottet werden. Das erreicht man, wie oben erwähnt, mit einem separaten einfachen Deckel 22, der anstelle der Mischspritzdüse 15 auf das Gewinde 16 geschraubt wird. Das Röhrchen 18, das mit mindestens drei Verbindungsstegen 24 mit den Innenwänden der Austrittsöffnung 17 verbunden ist, schliesst bündig mit dem aufgeschraubten Deckel ab. Damit ist die Abschottung der beiden Komponenten perfekt. Es sei noch erwähnt, dass bei der Spezialspritzdüse der innere Folienschlauch für die zweite Komponente an den Innenwänden des Röhrchens 18 angeleimt oder ange- schweisst wird. Besondere Sorgfalt ist auch beim Zusammenschnüren oder Verschweissen der Enden 11 angebracht. Man hilft sich so, dass zuerst der innere Folienschlauch 14 verschlossen wird und erst danach der äussere Folienschlauch 13, um zu verhindern, dass die beiden Komponenten mitei¬ nander in Berührung kommen. Dabei muss lediglich darauf geachtet werden, dass der innere Folienschlauch 13 sicher mit dem äusseren Folienschlauch verschnürt oder verschweisst ist, das heisst, dass der innere und äussere Folienschlauch mechanisch verbunden sind. Damit wird verhindert, dass beim Auspressen der innere Folienschlauch 13 sich im Inneren des Folien- schlauchs 14 verwinden kann, ohne dass er ausgepresst würde. Um den eigentlichen Zweck der Mischspritzdüse 15, nämlich das Mischen zweier Komponenten, zu erfüllen, ist ein sogenannter Flügelmischer 19 vorhanden. Dieser ist,wie in Fig. 4 gezeigt, in die Mischspritzdüse einge¬ setzt. Der Flügelmischer besteht aus mehreren Mischerteilen 20, die anei¬ nander gereiht sind. Dabei sind die Flügel 21 der einzelnen Mischerteile gegeneinander versetzt. Die Flügelkanten sind ferner abgeschrägt, damit der Flügelmischer 19 satt in die Mischspritzdüse eingesetzt werden kann. Je nach Material sind die einzelnen Mischerteile 20 miteinander ver¬ schweisst oder mit einer axialen Bohrung versehen, damit sie zum Beispiel auf eine Metallachse gesteckt werden können. Es fällt nun auf, dass die Mischspritzdüse 15 länger als die vorher erwähnten Düsen ist. Damit wird erreicht, dass der Flügelmischer 19 entsprechend lang gebaut werden kann. Somit ist der Weg, auf dem die beiden Komponenten durchgeknetet werden, lang genug, um eine optimale Durchmischung der beiden Komponenten zu erhalten. Damit ist eine qualitativ hochwertige Verarbeitung von Zweikom¬ ponenten-Kitten oder Zweikomponenten-Klebstoffen von vornherein gewähr¬ leistet. Ein weiterer stark geschätzter Vorteil von der langen Misch¬ spritzdüse 15 ist der, dass vor allem Zweikomponenten-Dichtstoffe/- Klebstoffe sehr leicht in Bohrungen von Hohlraummauerwerk gespritzt wer¬ den können, um so Dübel auf sichere Art und Weise zu befestigen. Die Mischspritzdüse 15 ist übrigens einfach zu reinigen, da der Flügelmi- scher 19 leicht herausgenommen werden kann.Depending on the type of components used, it may be necessary to use a special spray nozzle 15 (FIG. 4) which mixes the two components. This is screwed onto the external thread 16 of the round outlet opening 17 of the first component. The reason why the mixing spray nozzle 15 does not form a part with the base 3 (FIG. 1) is that components can also be mixed in this way which react strongly with one another even with small amounts. If a sealing cap were simply put on the nozzle, it would not be guaranteed that the two-component cement or two-component adhesive would not be cured. To ensure this, the two components must be isolated from each other. This is achieved, as mentioned above, with a separate, simple cover 22, which is screwed onto the thread 16 instead of the mixing spray nozzle 15. The tube 18, which is connected to the inner walls of the outlet opening 17 with at least three connecting webs 24, is flush with the screwed-on cover. The partitioning of the two components is thus perfect. It should also be mentioned that in the special spray nozzle, the inner film tube for the second component is glued or welded to the inner walls of the tube 18. Special care is also taken when tying or welding the ends 11 together. It is thus helped that first the inner film tube 14 is closed and only then the outer film tube 13 in order to prevent the two components from coming into contact with one another. It is only necessary to ensure that the inner film tube 13 is securely tied or welded to the outer film tube, that is to say that the inner and outer film tubes are mechanically connected. This prevents the inner film tube 13 from squeezing inside the film hose 14 can twist without being squeezed. In order to fulfill the actual purpose of the mixing spray nozzle 15, namely the mixing of two components, a so-called wing mixer 19 is provided. As shown in FIG. 4, this is inserted into the mixing spray nozzle. The wing mixer consists of several mixer parts 20 which are lined up. The wings 21 of the individual mixer parts are offset from one another. The wing edges are also bevelled so that the wing mixer 19 can be inserted fully into the mixing spray nozzle. Depending on the material, the individual mixer parts 20 are welded to one another or provided with an axial bore so that, for example, they can be plugged onto a metal axis. It is now noticeable that the mixing spray nozzle 15 is longer than the previously mentioned nozzles. This ensures that the wing mixer 19 can be built accordingly long. Thus, the way in which the two components are kneaded is long enough to achieve optimal mixing of the two components. This ensures high-quality processing of two-component putties or two-component adhesives from the outset. Another greatly appreciated advantage of the long mixing spray nozzle 15 is that, above all, two-component sealants / adhesives can be sprayed very easily into bores in cavity masonry, in order to secure dowels in a safe manner. Incidentally, the mixing spray nozzle 15 is easy to clean, since the wing mixer 19 can be easily removed.
Auch bei der Mischspritzdüse und dem zugehörigen einfachen Deckel ist es denkbar, diese unverlierbar anzubringen.It is also conceivable for the mixing spray nozzle and the associated simple cover to be attached so that it cannot be lost.
Abschliessend sei noch darauf hingewiesen, dass die Folienkartuschen nicht unbedingt aus hochreissfester Folie hergestellt werden müssen. Nor¬ mal belastbare Folie kann durch einen gekreuzt aufgewickelten Faden 25 verstärkt werden. Durch günstige Wahl des Abstandes zwischen den Fäden kann die gewünschte Festigkeit der Umhüllung erzielt werden (Schutz vor Beschädigung). Damit wird übrigens auch der Umgang mit den Folienkartu¬ schen vereinfacht, muss man doch beim Transport und bei der Handhabung weniger Acfr geben. Besonders für die rauhen Bedingungen auf Baustellen ist das ein Dedeutender Vorteil. Die neuen Folienkartuschen sind extrem vielseitig einsetzbar, vor allem die Zweikomponentenkartuschen. Der verminderte Materialbedarf und die auf den Einsatz in Dauerkartuschen abgestimmten Abmessungen werden die bis heute verwendeten Einwegkartuschen aus dickwandigen Kunststoffdosen vom Markt verdrängen und gleichzeitig neue Anwendungsbereiche erschliessen. Finally, it should be pointed out that the film cartridges do not necessarily have to be made from highly tear-resistant film. Normally resilient film can be reinforced by a cross wound thread 25. The desired strength of the covering can be achieved by a favorable choice of the distance between the threads (protection against damage). Incidentally, this also simplifies the handling of the film cartridges, since less Acfr has to be given during transport and handling. This is a significant advantage, especially for the rough conditions on construction sites. The new foil cartridges are extremely versatile, especially the two-component cartridges. The reduced material requirements and the dimensions matched to the use in permanent cartridges will replace the disposable cartridges made of thick-walled plastic cans that have been used to date, and at the same time open up new areas of application.
