Description

Die Erfindung betrifft eine Vorrichtung zur Durchführung einer mischenden Abgabe von mehreren fliessfähigen Komponenten aus einem mehrkammerigen Behältnis gemäss Oberbegriff von Anspruch 1 sowie Verwendungen der Vorrichtung. Das mehrkammerige Behältnis kann auch eine Mehrzahl von Behältern oder Behältnissen sein, die zu einer Einheit zusammengefasst sind.The invention relates to a device for carrying out a mixing Delivery of several flowable components from one multi-chamber container according to the preamble of claim 1 and Uses of the device. The multi-chamber container can also a plurality of containers or containers that form one unit are summarized.

Aus der US-A 5 413 253 und der EP-A 0 723 807 sind Vorrichtungen mit statischen Mischern der gattungsgemässen Art bekannt, mit denen aus jeweils einem Vorratsbehältnis, nämlich einer Kartusche mit zwei Kammern, fliessfähige Komponenten als Mischungen abgegeben werden können. Solche Zweikomponentenmischungen werden zu Dichtungs- und/oder Klebzwecken verwendet. Aufgrund von Reaktionen zwischen den Komponenten verfestigt sich die Mischung. In der Regel will man aus einem gegebenen Vorrat von Komponenten zu verschiedenen, auseinanderliegenden Zeitpunkten Mischungen entnehmen können. Nach einer solchen Entnahme verfestigt sich das reaktive Komponentengemisch im statischen Mischer, da es mit der Zeit aushärtet. Für die Durchführung einer späteren Abgabe muss die Mischvorrichtung ersetzt werden. Deshalb sind solche Vorrichtungen als Wegwerfware vorgesehen, die möglichst wenig kosten sollen. Devices are known from US Pat. No. 5,413,253 and EP-A 0 723 807 static mixers of the generic type known with which one storage container each, namely a cartridge with two chambers, flowable components can be dispensed as mixtures. Such two-component mixtures become seals and / or Used for sticking purposes. Due to reactions between the Components solidify the mixture. Usually you want one given stock of components to different, can find mixtures that are separated from one another. To Such a removal solidifies the reactive component mixture in the static mixer as it hardens over time. For carrying out a the mixer must be replaced later. That is why such devices are provided as disposable, as little as possible should cost.

Mit einem geeignet ausgebildeten Übergangsstück, das zwischen den Austrittsöffnungen der Kartusche und dem statischen Mischer angeordnet ist und das Zuführkanäle enthält, wird verhindert, dass im Bereich der Austrittsöffnungen eine Reaktion einsetzen kann. Die in den Zuführkanälen enthaltenen Komponenten wirken als Barrieren, die eine Verunreinigung der Komponenten in der Kartusche aufgrund einer Vermischung der Komponenten verhindern. Beim Austausch einer benutzten Mischervorrichtung wird das Übergangsstück zusammen mit der Vorrichtung entfernt, so dass aus der Kartusche erneut reines, reaktionsfähiges Material entnommen werden kann.With a suitably trained transition piece, which between the Outlet openings of the cartridge and the static mixer is arranged and which contains feed channels, is prevented in the area of Outlet openings can start a reaction. The in the feed channels Components contained act as barriers that prevent contamination of the Components in the cartridge due to mixing of the Prevent components. When replacing a used one Mixer device becomes the transition piece together with the device removed, so that again pure, reactive material from the cartridge can be removed.

Ein Positionierungsmittel 32" ist gestrichelt angedeutet.Fig. 4 shows the area of the transition piece 11 of a second Embodiment in which the coupling means 15 separately on the Transition part 11 comprises applied part 6, which by means of a detachable Snap lock (6 ', 61, 26; 6 ") can be attached to the container 2. The part 6 consists of a coupling ring 60 and two resilient legs 6 'and 6 ", which have feet 61 in corresponding recesses 26 of the container 2 are hookable. The dash-dotted leg 6 "lies in front of the Drawing level. The transition piece 3 consists of an elastomer Material that - as shown in the drawing - corresponds to one The inner shape of the transition part 11 is shaped and can be pressed into it is trained. A positioning means 32 "is indicated by dashed lines.

Bei einer Zweikomponentenkartusche sind die Zuführkanäle 31, 31' des Übergangsteils zwei zylindrische Durchbrüche, deren Achsen parallel oder geneigt (siehe Fig. 1 bzw. 4) zueinander von den Austrittsöffnungen 21 des Behältnisses 2 zu dem statischen Mischer 4 führen.In the case of a two-component cartridge, the feed channels 31, 31 'of the Transitional part two cylindrical openings, the axes of which are parallel or inclined (see Fig. 1 and 4) to each other from the outlet openings 21 of the Lead container 2 to the static mixer 4.

In Fig. 5 ist der Bereich des Übergangsstücks 11 einer dritten Ausführungsform dargestellt. Entsprechend der Vorrichtung, die aus der US-A 5 413 253 bekannt ist, dienen zur Fixierung einer drehfesten Position zwei hülsenfömige Positionierungsmittel 33, die gleichzeitig die Zuführkanäle 31 bilden. Die derart konstruierten Positionierungsmittel 33 haben den Vorteil, dass beim Wechsel der Vorrichtung 1 aus den Austrittsöffnungen 21 des Behältnisses 2 ein Teil des Inhalts, der verunreinigt sein kann, mitentfernt wird.5, the area of the transition piece 11 is a third Embodiment shown. According to the device that is known from US-A 5 413 253 is known, serve to fix a rotationally fixed position two sleeve-shaped positioning means 33, which simultaneously the feed channels 31st form. The positioning means 33 constructed in this way have the advantage that when changing the device 1 from the outlet openings 21 of the Container 2 removes part of the content that may be contaminated becomes.

Zusätzliche Dichtrippen 34 und 35 vor dem Mischer 4 verhindern, dass die Komponenten seitlich in die Umgebung austreten. Die Dichtrippe 35, die am äusseren Umfang des Übergangsstück 3 angeordnet ist, bildet zusammen mit einer Ringnut 135, in die die Dichtrippe 35 eingeschnappt ist, eine Verankerung im Übergangsteil 11.Additional sealing ribs 34 and 35 in front of the mixer 4 prevent the Eject components laterally into the environment. The sealing rib 35, the outer circumference of the transition piece 3 is arranged together with an annular groove 135 into which the sealing rib 35 is snapped, one Anchoring in the transition part 11.

Fig. 6 zeigt ein Beispiel, bei dem im Unterschied zu jenem der Fig. 5 das Übergangsteil 11 durch eine Überwurfmutter 5 auf dem Behältnis 2 befestigbar ist. Bei diesem Ausführungsbeispiel - wie auch bei dem in Fig. 4 dargestellten - muss das Übergangsstück 3 nicht drehbar ausgebildet sein. FIG. 6 shows an example in which, in contrast to that of FIG. 5, the Transition part 11 by means of a union nut 5 on the container 2 is attachable. In this embodiment - as also in that in FIG. 4 shown - the transition piece 3 does not have to be rotatable.

Seine Aussenkontur, die in das Übergangsteil 11 passend geformt sein muss, kann einen Querschnitt haben, dessen Aussenseiten ein gleichmässiges Vieleck bilden. Ist dieses Vieleck beispielsweise ein Sechseck, so gibt es sechs diskrete Drehstellungen, in denen das Übergangsstück 3 in das Übergangsteil 11 einfügbar ist. Damit eine gute Abdichtung gegen aussen vorliegt, kann das Übergangsstück 3 auch in das Übergangsteil 11 eingeklebt, eingeschweisst oder mit diesem sonstwie unlösbar verbunden werden (durch Schrumpfen oder Einpressen in einen Passsitz). Mit einer solchen unlösbaren Fixierung wird auch verhindert, dass das Übergangsstück 3 aus dem Übergangsteil 11 herausfallen kann. Zwischen Übergangsstück 3 und Übergangsteil 11 kann bei den hohen Drücken, die beim Dosieren im Mischer auftreten können (bis 20 bar), kein Produkt seitlich entweichen. Das Fixieren des Übergangsstücks 3 hat im weitern den Vorteil, dass das Übergangsstück 3 beim Ersatz eines gebrauchten Mischers nicht auf einer Kartusche stecken bleibt, so dass der neue Mischer ohne Probleme auf die angebrauchte Kartusche gesteckt werden kann.Its outer contour, which must be shaped to fit into the transition part 11, can have a cross section, the outer sides of which are uniform Form polygon. For example, if this polygon is a hexagon, there are six discrete rotary positions, in which the transition piece 3 in the Transitional part 11 is insertable. So that a good seal against the outside is present, the transition piece 3 can also be glued into the transition part 11, welded in or otherwise inseparably connected to it (by Shrink or press fit). With such an unsolvable Fixation is also prevented that the transition piece 3 from the Transition part 11 can fall out. Between transition piece 3 and Transition part 11 can at the high pressures that occur in the mixer can occur (up to 20 bar), no product can escape laterally. The fixation The transition piece 3 also has the advantage that the transition piece 3 When replacing a used mixer, do not put it on a cartridge remains, so the new mixer can be used on the used one without any problems Cartridge can be inserted.

Fig. 7 zeigt ein Übergangsteil 11 einer erfindungsgemässen Vorrichtung zu einer Kartusche 2 mit "Zentraldosierung": Die Zuführkanäle - und entsprechendes gilt für die Austrittsöffnungen der Kartusche 2 - werden durch einen zentralen angeordneten, zylindrischen Durchbruch 31a und einen dazu konzentrisch angeordneten, ringspaltförmigen Durchbruch 31b gebildet.7 shows a transition part 11 of a device according to the invention a cartridge 2 with "central metering": the feed channels - and the same applies to the outlet openings of the cartridge 2 - are by a centrally arranged cylindrical opening 31a and one to it concentrically arranged, annular gap-shaped opening 31b is formed.

Für den Mischer 4 wird mit Vorteil eine Struktur gewählt, die in der EP-A 0 815 929 (= P.6741) beschrieben ist: Diese Struktur ist aus einem Bündel von vier parallelen, quaderförmige Kammern umfassenden Strängen gebildet; die Kammern sind über Öffnungen - deren Anzahl in der Regel vier beträgt - mit Kammern benachbarter Stränge verbunden, wobei innerhalb eines Strangs die Kammern durch geschlossene Wände voneinander getrennt sind. Eine solche Mischerstruktur ergibt über eine vergleichsweise kurze Strecke gute Mischresultate. Die Einlaufbedingungen, die von der Drehstellung des Übergangsstücks 3 gegenüber der Mischerstruktur 4 abhängen, haben keinen störenden Einfluss auf die Mischqualität.A structure is advantageously chosen for the mixer 4, which is described in EP-A 0 815 929 (= P.6741): This structure is made up of a bundle of four parallel, parallelepiped-shaped strands formed strands; the Chambers are with openings - the number of which is usually four - with Chambers of adjacent strands connected, being within one strand the chambers are separated from each other by closed walls. A such a mixer structure gives good results over a comparatively short distance Mixed results. The running-in conditions, which depend on the rotational position of the Transition piece 3 depend on the mixer structure 4, have none disruptive influence on the mixing quality.

Das zwei- oder mehrkammerige Behältnis 2 kann auch Teil einer Dosiereinrichtung sein, bei der die Kammern des Behältnisses 2 Durchtrittsräume für zu dosierende und separat zuzuführende Mengen von zu mischenden Komponenten sind.The two- or multi-chamber container 2 can also be part of one Dosing device in which the chambers of the container 2 Passage areas for quantities to be dosed and separately supplied are mixing components.
