Abstract

A container comprises a tubular film 11 for flowable products. The opened tubular film can be placed in a cylindrical housing 31 between a cap 33 and a displaceable plunger 32. At the end of the tubular film 11 facing the cap 33, said tubular film is provided with a ring 20 which has a conical sealing surface 21. When the contents of the tubular film 11 are discharged by advancing the plunger 32, said sealing surface 21 is pressed against a counter-surface 35 of the cap 33 which surrounds the discharge aperture 34. The contents of the tubular film 11 are thus prevented from leaking onto the inside wall of the housing. <IMAGE>

Description

Die Erfindung betrifft einen Behälter mit Folienschlauch für eine fließfähige Substanz.The invention relates to a container with a film tube for a flowable substance.

Solche Behälter dienen als Einweg-Verpackungen beispielsweise für Klebstoffe, Dicht- und Formmassen oder andere aushärtbare Substanzen.Such containers serve as disposable packaging, for example for adhesives, sealing and molding compounds or other curable substances.

Aus DE-A-3 823 708 sind Behälter für voneinander getrennte pastöse Komponenten bekannt, die in exakt definiertem Mengenverhältnis ausgebracht und einem Mischer zugeführt werden können. Jede Komponente ist dort in einer steifen Kartusche enthalten, die an einer Seite mit einem Austrittsstutzen und an der anderen Seite von einem verschiebbaren Kolben abgeschlossen ist.DE-A-3 823 708 discloses containers for separate pasty components which can be applied in a precisely defined quantity ratio and fed to a mixer. Each component is contained in a rigid cartridge, which is sealed on one side with an outlet nozzle and on the other side with a sliding piston.

Der bekannte, als feste Kartusche ausgebildete Behälter erlaubt zwar die exakte Dosierung der Komponenten, ist jedoch verhältnismäßig aufwendig und bedarf zur ausreichenden Abdichtung des Kolbens einer toleranzgenauen Fertigung. Außerdem stellen steife Kartuschen als Einwegbehälter bei der Entsorgung ein Problem dar, das zunehmend ernst genommen wird.The known container, which is designed as a solid cartridge, allows the exact metering of the components, but is relatively complex and requires a tolerance-accurate production for sufficient sealing of the piston. In addition, stiff cartridges as disposable containers are a problem that is increasingly being taken seriously.

Aus diesen Gründen ist man dazu übergegangen, als Einweg-Verpackungen für fließfähige Substanzen Folienschläuche einzusetzen, die in eine zylindrische Kammer eingelegt werden, in der ihr Inhalt aus dem aufgeschnittenen Schlauch herausgedrückt werden kann. Bei derartigen Behältern ist lediglich der Folienschlauch ein Einwegteil. Er ist in der Herstellung billig und nimmt im entleerten Zustand nur wenig Platz ein. Solche Behälter sind beispielsweise in DE-A-3 826 887, DE-U-8 901 554 und US-A-3 838 796 beschrieben.For these reasons, it has become common to use film tubes as disposable packaging for flowable substances, which are inserted into a cylindrical chamber in which their contents can be pressed out of the cut tube. In such containers, only the film tube is a disposable part. It is cheap to manufacture and takes up little space when empty. Such containers are described for example in DE-A-3 826 887, DE-U-8 901 554 and US-A-3 838 796.

Die bekannten Behälter mit Folienschläuchen haben jedoch den Nachteil, daß die aus dem aufgeschnittenen Folienschlauch austretende Substanz das Innere der zylindrischen Kammer verschmutzt und nach einiger Zeit die Bewegung des Kolbens hemmt und den Behälter unbrauchbar macht. Da ein Teil der Substanz nicht nur durch die Ausbringöffnung entweicht, sondern auch aus dem Folienschlauch in das Innere der zylindrischen Kammer fließt, ist eine exakte Dosierung der Substanz unmöglich. Dies stellt insbesondere bei Substanzen, die eine Komponente eines mit exakten Mengenverhältnissen zu mischenden Stoffes sind, einen schweren Nachteil dar.However, the known containers with film tubes have the disadvantage that the substance emerging from the cut film tube contaminates the interior of the cylindrical chamber and after some time inhibits the movement of the piston and renders the container unusable. Since part of the substance not only escapes through the discharge opening, but also flows out of the film tube into the interior of the cylindrical chamber, an exact dosage of the substance is impossible. This is a serious disadvantage, especially for substances that are a component of a substance to be mixed with exact proportions.

Um diese Nachteile zu vermeiden, verwendet die Firma Teroson für die von ihnen vertriebenen Dichtstoffe eine Schlauchpackung, die auf einer Stirnseite einen außen aufgeklebten Ring aufweist. Dieser Ring ist mit einem Gewinde zur Verbindung mit einem Austrittsstutzen versehen. Der Austrittsstutzen weist Messer auf, die beim Zusammenschrauben aus dem Folienschlauch innerhalb des Rings eine Öffnung herausschneiden. Nach dem Aufschneiden muß der Austrittsstutzen noch einmal abgeschraubt werden, um das herausgeschnittene Folienstück zu entfernen, da es sonst den Austrittsstutzen verstopfen würde. Diese Handhabung ist sehr umständlich und unsauber.To avoid these disadvantages, Teroson uses a hose pack for the sealants they sell, which has an externally glued ring on one end. This ring is provided with a thread for connection to an outlet nozzle. The outlet connector has knives that cut an opening out of the film tube within the ring when screwed together. After cutting, the outlet nozzle must be unscrewed again in order to remove the cut-out piece of film, since it would otherwise clog the outlet nozzle. This handling is very cumbersome and dirty.

Eine ähnlich gestaltete und und in der Handhabung ähnlich umständliche Schlauchpackung, die die im ersten Teil des Anspruchs 1 enthaltenen Merkmale aufweist, ist aus DE-A-3 500 625 bekannt.A similarly designed and similarly cumbersome handling hose pack, which has the features contained in the first part of claim 1, is known from DE-A-3 500 625.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Behälter für eine fließfähige Substanz anzugeben, der nur eine geringe Menge an Einweg-Material enthält und dennoch einfach und sauber zu handhaben ist und eine genaue Dosierung der Substanz zuläßt.The invention is therefore based on the object of specifying a container for a flowable substance which contains only a small amount of disposable material and is nevertheless simple and clean to handle and permits precise dosing of the substance.

Die erfindungsgemäße Lösung dieser Aufgabe ist in Anspruch 1 angegeben. Demnach ist der Folienschlauch mit einem Ring versehen, der eine konische Dichtfläche aufweist. Eine mit dieser zusammenwirkende ebensolche Dichtfläche umgibt eine in einer starren Kappe des Behälters angebrachte Ausbringöffnung. Zur Verwendung des Behälters wird der Folienschlauch innerhalb des Rings aufgeschnitten und dann so in ein zylindrisches Gehäuse eingesetzt, daß sich die Dichtfläche des Rings gegen die Gegenfläche der starren Kappe schiebt.The solution to this problem according to the invention is specified in claim 1. Accordingly, the film tube is provided with a ring which has a conical sealing surface. A sealing surface cooperating with this surrounds a discharge opening made in a rigid cap of the container. To use the container, the film tube is cut open within the ring and then inserted into a cylindrical housing in such a way that the sealing surface of the ring pushes against the counter surface of the rigid cap.

Eine konische Dichtfläche hat den Vorteil, daß sich der Folienschlauch beim Einlegen in das zylindrische Gehäuse automatisch zentriert. Die konische Ausführung der Dichtflächen bewirkt außerdem eine Erhöhung der dichtenden Andruckkraft. Somit wird verhindert, daß die in dem Folienbehälter befindliche Substanz das Gehäuseinnere, insbesondere die Gleitflächen des Kolbens, verschmutzt. Der entleerte Folienbehälter läßt sich problemlos entnehmen, ohne wie bei konventionellen Behältern, bedingt durch die ausgelaufene Substanz, an der Gehäuseinnenwand zu kleben. Die dichtende Funktion des Rings gewährleistet einer präzise Dosierung der Substanz. Außerdem verhindert der Ring, daß der aufgeschnittene Folienbehälter zu weit aufreißt.A conical sealing surface has the advantage that the film tube is automatically centered when it is inserted into the cylindrical housing. The conical design of the sealing surfaces also increases the sealing pressure. This prevents the substance in the film container the interior of the housing, especially the sliding surfaces of the piston, is dirty. The emptied foil container can be easily removed without sticking to the inside wall of the housing due to the leaked substance, as with conventional containers. The sealing function of the ring ensures precise dosing of the substance. In addition, the ring prevents the cut open film container from tearing open too far.

Die Maßnahmen der Ansprüche 2 bis 4 bewirken eine dichte und stabile Befestigung des Rings an dem Folienschlauch.The measures of claims 2 to 4 bring about a tight and stable attachment of the ring to the film tube.

Die Weiterbildungen nach den Ansprüchen 5 bis 8 haben den Vorteil, daß die Klammer, die den Folienschlauch verschnürt und verschließt, nicht in den Ring hineinrutschen kann. Der von der Klammer zusammengeschnürte Teil des Folienschlauches läßt sich somit auf einfache Weise mit einem Seitenschneider oder einer Schere zum Öffnen des Schlauches an einer definierten Stelle abschneiden. Dabei verhindert der Ring, daß sich der Folienschlauch zu weit öffnet und der Inhalt vorzeitig ausfließt.The further developments according to claims 5 to 8 have the advantage that the clip which ties and seals the film tube cannot slip into the ring. The part of the film tube constricted by the clip can thus be cut off in a simple manner with a side cutter or a pair of scissors to open the tube at a defined point. The ring prevents the film tube from opening too far and the contents from flowing out prematurely.

Gemäß Figur 1 ist ein Folienschlauch 11 an beiden Enden jeweils mit einer Klammer 12 verschlossen. An einer der beiden Stirnseiten befindet sich zwischen dem gefüllten Teil des Folienschlauchs 11 und der Klammer 12 ein Ring 20. Der Ring 20 liegt mit einer schmalen Kante 24 am Folienschlauch an. An der Kante 24 ist der Ring 20 außerdem durch Klebstoff mit dem Folienschlauch 11 verbunden.According to Figure 1, a film tube 11 is closed at both ends with a clip 12. On one of the two end faces there is a ring 20 between the filled part of the film tube 11 and the clip 12. The ring 20 lies against the film tube with a narrow edge 24. At the edge 24, the ring 20 is also connected to the film tube 11 by adhesive.

Der Ring 20 ist mit zwei zungenförmigen Rasten 22 versehen, die als Abstandshalter zur Klammer 12 wirken. Somit kann die Klammer 12 nicht in das Innere des Rings hineinrutschen. Dies erleichtert das Öffnen des Folienschlauchs 11 durch Abschneiden des von der Klammer 12 zusammengehaltenen, verschlossenen Teils des Folienschlauches 11. Zur bequemen Handhabung sind in dem Ring 20 im Bereich der Abstandshalter 22 Kerben 23 vorgesehen, an denen mit einer Schere oder einem Seitenschneider angesetzt werden kann, um den Folienschlauch aufzuschneiden, ohne daß die Gefahr eines Abrutschens besteht. Die Rasten 22 lassen sich federnd nach außen drücken und erlauben somit, daß der Ring 20 bei der Herstellung der Verpackung über die geschlossene Klammer 12 auf den Schlauch aufgezogen werden kann, wo er festgeklebt wird. Das Festkleben verhindert, daß sich der Ring 20 nach dem Aufschneiden vom Folienschlauch 11 löst.The ring 20 is provided with two tongue-shaped catches 22, which act as a spacer from the clip 12. Thus, the clip 12 cannot slip inside the ring. This facilitates the opening of the film tube 11 by cutting off the closed part of the film tube 11 held together by the clip 12. For convenient handling, notches 23 are provided in the ring 20 in the area of the spacers 22, which can be attached with scissors or a side cutter to cut open the film tube without the risk of slipping. The catches 22 can be pressed resiliently outward and thus allow the ring 20 to be pulled over the closed clamp 12 onto the hose during the manufacture of the packaging, where it is glued on. The sticking prevents the ring 20 from becoming detached from the film tube 11 after being cut open.

Figur 2 zeigt den geöffneten Folienschlauch 11 in einem zylindrischen Gehäuse 31 liegend. Dabei befindet sich eine konische Dichtfläche 21 des Rings 20 in festem, dichtenden Kontakt mit einer Gegenfläche 35 einer an der Stirnseite des Gehäuses 31 vorgesehenen Kappe 33. Die Gegenfläche 35 umgibt die in einer Kappe 33 vorgesehene Ausbringöffnung 34 für die in dem Folienbehälter 11 befindliche Substanz.FIG. 2 shows the opened film tube 11 lying in a cylindrical housing 31. A conical sealing surface 21 of the ring 20 is in firm, sealing contact with a counter surface 35 of a cap 33 provided on the end face of the housing 31. The counter surface 35 surrounds the dispensing opening 34 provided in a cap 33 for the substance located in the film container 11 .

Die Ausbringöffnung 34 ist als gekröpfter Kanal ausgeführt, der es ermöglicht, daß die Substanzen zweier nebeneinander liegender Behälter dieser Bauart in dicht nebeneinander liegenden Kanälen einem (nicht dargestellten) Mischer zugeführt werden. Die gekröpfte Anordnung des Kanals 34 ist somit bei Behältern für Mehrkomponenten-Werkstoffe vorteilhaft.The discharge opening 34 is designed as a cranked channel, which enables the substances of two containers of this type lying next to one another to be fed to a mixer (not shown) in channels lying closely next to one another. The cranked arrangement of the channel 34 is thus advantageous in containers for multi-component materials.

Durch Druck auf einen an der anderen Stirnseite des Behälters vorgesehenen Kolben 32 läßt sich der Inhalt des Folienschlauches 11 ausbringen. Dabei wird der Ring 20 mit seiner konischen Dichtfläche 21 gegen die Gegenfläche 35 gedrückt und verkeilt sich in der Kappe 33. Wegen der geringen Fläche der auf den Folienschlauch 11 hin zugespitzten Kante 24 wirkt außerdem ein hoher dichtender Anpreßdruck zwischen dem Ring 20 und dem Folienschlauch 11. Dadurch kann der Inhalt des Folienschlauchs 11 weder zwischen dem Ring 20 und der Kappe 33 noch zwischen dem Folienschlauch 11 und dem Ring 20 hindurch an die Gehaüseinnenwand gelangen. Der entleerte Folienschlauch, der nach Zurückziehen des Kolbens 32 aus dem Gehäuse 31 entnommen wird, ist daher außen nicht verschmutzt. Auch die Innenwand des Gehäuses 31 bleibt frei von Verunreinigungen durch den Inhalt des Folienschlauchs 11, die die Bewegung des Kolbens 32 behindern könnten.The contents of the film tube 11 can be discharged by pressure on a piston 32 provided on the other end of the container. The ring 20 with its conical sealing surface 21 is pressed against the counter surface 35 and wedged in the cap 33. Because of the small area of the edge 24 tapered onto the film tube 11, a high sealing contact pressure also acts between the ring 20 and the film tube 11 As a result, the content of the film tube 11 can neither between the ring 20 and the cap 33 nor get between the film tube 11 and the ring 20 to the inner wall of the housing. The emptied film tube, which is removed from the housing 31 after the piston 32 has been pulled back, is therefore not contaminated on the outside. The inner wall of the housing 31 also remains free of contamination from the contents of the film tube 11, which could hinder the movement of the piston 32.

Da der Ring 20 mit dem Folienschlauch 11 verklebt ist, wird er beim Herausziehen des Folienschlauchs 11 mit entnommen. Wegwerfteile sind somit nur der Folienschlauch 11 mit den beiden Klammern 12 und dem Ring 20. Je nach gewünschter Größe der Öffnung des Schlauchs 11, läßt sich der Ring so klein wie möglich gestalten, so daß die Abfallmenge begrenzt bleibt.Since the ring 20 is glued to the film tube 11, it is also removed when the film tube 11 is pulled out. Disposable parts are thus only the film tube 11 with the two clips 12 and the ring 20. Depending on the desired size of the opening of the tube 11, the ring can be made as small as possible so that the amount of waste remains limited.

Figur 3 zeigt die Teilansicht eines Folienschlauchs 11, der mit einem sehr kleinen Ring 20 versehen ist. Der Innendurchmesser dieses Rings ist kleiner als der Außendurchmesser der Klammer 12. Dies macht die Verwendung des in Figur 1 mit 22 bezeichneten Abstandshalters überflüssig. Um den Ring 20 dennoch nach dem Verschließen des Folienschlauchs 11 durch die Klammer 12 anbringen zu können, besteht er in dieser Ausführungsform aus zwei halbringförmigen Teilen 25 und 26. Beide Teile werden nach dem Anlegen an den Folienschlauch miteinander verklebt oder verklemmt. Bedingt durch das Zusammenwirken der konischen Dichtfläche 21 mit der Gegenfläche 35 werden die beiden Ringteile 25 und 26 im Gebrauch fest aneinandergedrückt, so daß die Dichtheit der Verbindung zwischen den Ringteilen 25 und 26 kein Problem darstellt.Figure 3 shows the partial view of a film tube 11, which is provided with a very small ring 20. The inside diameter of this ring is smaller than the outside diameter of the clamp 12. This makes the use of the spacer designated 22 in FIG. 1 superfluous. In order to be able to attach the ring 20 after the film tube 11 has been closed by the clip 12, in this embodiment it consists of two semi-ring-shaped parts 25 and 26. Both parts are glued or clamped together after being placed on the film tube. Due to the interaction of the conical sealing surface 21 with the counter surface 35, the two ring parts 25 and 26 are pressed tightly together during use, so that the tightness of the connection between the ring parts 25 and 26 is not a problem.

Das Fehlen des Abstandshalters bewirkt, daß der Ring 20 sehr flach ist und das Füllvolumen des Folienschlauches kaum einschränkt.The absence of the spacer means that the ring 20 is very flat and hardly limits the filling volume of the film tube.

Figur 4 zeigt die Explosionsdarstellung eines Behälters für ein Zweikomponenten-Substanz. Für jede der Komponenten ist ein Folienschlauch 11 vorgesehen, der wie oben beschrieben mit Klammern 12 verschlossen ist und jeweils einen Ring 20 aufweist.Figure 4 shows the exploded view of a container for a two-component substance. A film tube 11 is provided for each of the components, which is closed with clips 12 as described above and each has a ring 20.

Jeder der Folienschläuche 11 ist in eine von zwei zylindrischen Kammern 47, 48 eines Doppelzylinders 41 eingelegt. An einer Stirnseite des Doppelzylinders 41 ist eine Kappe 43 vorgesehen, die für jede der Gehäusekammern 47, 48 jeweils mit einer Ausbringöffnung 44, 45 versehen ist.Each of the film tubes 11 is inserted into one of two cylindrical chambers 47, 48 of a double cylinder 41. At An end face of the double cylinder 41 is provided with a cap 43 which is provided with a discharge opening 44, 45 for each of the housing chambers 47, 48.

Beide Ausbringöffnungen 44 und 45 sind als gekröpfte Kanäle ausgebildet, die dicht nebeneinanderliegend in eine Düse 50 münden. Zur Befestigung der Düse 50 an der Kappe 43 ist ein Bajonettverschluß 51, 46 vorgesehen, der jedoch auch durch einen Schraubverschluß ersetzt werden kann.Both discharge openings 44 and 45 are designed as cranked channels which open into a nozzle 50 lying close to one another. To fasten the nozzle 50 to the cap 43, a bayonet lock 51, 46 is provided, which can, however, also be replaced by a screw lock.

Für jede der Gehäusekammern 47, 48 ist ein Kolben 42 vorgesehen. Auf der dem Folienschlauch zugewandten Seite des Kolbens 42 ist dieser so profiliert, daß er Ausnehmungen im Mittelbereich für die Klammer 12 des Folienschlauchs 11 und im Umfangsbereich für die sich zusammendrückende Folie des Folienschlauchs 11 aufweist. So wird ein möglichst vollständiges Ausbringen der im Folienschlauch 11 befindlichen Substanz ermöglicht.A piston 42 is provided for each of the housing chambers 47, 48. On the side of the piston 42 facing the film tube, the latter is profiled in such a way that it has recesses in the central region for the clip 12 of the film tube 11 and in the peripheral region for the compressing film of the film tube 11. In this way, the most complete possible application of the substance located in the film tube 11 is made possible.

Der in Figur 4 in zerlegtem Zustand dargestellte Behälter ist in Figur 5 zusammengesetzt und in eine Dosierpistole 60 eingelegt abgebildet.The container shown in the disassembled state in FIG. 4 is assembled in FIG. 5 and shown inserted in a dosing gun 60.

Beide Kolben 42 werden gemeinsam von einer einzigen U-förmigen Kolbenstange 62 betätigt. Der Vorschub erfolgt schrittweise durch Ziehen eines Vorschubhebels 64 gegen einen Pistolengriff 63.Both pistons 42 are operated together by a single U-shaped piston rod 62. The feed takes place step by step by pulling a feed lever 64 against a pistol grip 63.

Im Inneren der Düse 50 sind (nicht dargestellt) Mischerflügel angeordnet, die für eine Durchmischung der Zweikomponenten-Substanz beim Durchströmen der Düse 50 sorgen. Die Düse 50 ist somit als statischer Mischer etwa gemäß EP-A-0 378 806 ausgebildet.Mixer blades (not shown) are arranged in the interior of the nozzle 50, which ensure that the two-component substance is mixed as it flows through the nozzle 50. The nozzle 50 is thus designed as a static mixer, for example according to EP-A-0 378 806.

Beim dargestellten Ausführungsbeispiel münden die beiden Ausbringöffnungen 44 und 45 nebeneinander in die Düse 50. Eine bessere Durchmischung der beiden Komponenten läßt sich jedoch erzielen, wenn die Kappe 43 so gestaltet ist, daß beide Ausbringöffnungen konzentrisch in die Düse 50 münden.In the exemplary embodiment shown, the two discharge openings 44 and 45 open side by side into the nozzle 50. However, better mixing of the two components can be achieved if the cap 43 is designed in such a way that both discharge openings open concentrically into the nozzle 50.

Bei aushärtenden Zweikomponenten-Substanzen ist neben den Folienschläuchen 11 und den Ringen 20 auch die Düse 50 ein Wegwerfteil. Um demgegenüber die Kappe 43 stets wiederverwenden zu können, ist es bei gleich großen Folienschläuchen 11 wie im vorliegenden Ausführungsbeispiel zweckmäßig, die Folienschläuche 11, die Gehäusekammern 47 und 48 und die beiden Hälften der Kappe 43 farblich so zu kennzeichnen, daß der Benutzer jede Komponente der Substanz stets auf der gleichen Seite der Kappe 43 anordnet. So wird vermieden, daß jede Komponente bereits innerhalb der Ausbringöffnungen 44 und 45 in Kontakt mit Resten der anderen Komponente gerät, dadurch aushärtet und die Ausbringöffnungen sowie die Düse 50 verstopft.In the case of curing two-component substances, in addition to the film tubes 11 and the rings 20, the nozzle 50 is also a disposable part. In order, on the other hand, to be able to reuse the cap 43 at all times, it is the same size of film tubes 11 as in In the present exemplary embodiment, it is useful to color-code the film tubes 11, the housing chambers 47 and 48 and the two halves of the cap 43 in such a way that the user always arranges each component of the substance on the same side of the cap 43. It is thus avoided that each component already comes into contact with residues of the other component within the discharge openings 44 and 45, thereby hardening and clogging the discharge openings and the nozzle 50.

Im vorliegenden Ausführungsbeispiel beträgt das Mischungsverhältnis der beiden Komponenten 1:1. Bei anderen Mischungsverhältnissen sind entsprechend unterschiedliche Durchmesser der Folienschläuche 11 notwendig. Dadurch ist ein Verwechseln auch ohne farbliche Markierung ausgeschlossen.In the present exemplary embodiment, the mixing ratio of the two components is 1: 1. With other mixing ratios, different diameters of the film tubes 11 are necessary. This prevents confusion even without color coding.
