Diese Mehrkammertube ist aufwendig herzustellen, da mehrere separate Tuben und ein zusätzlicher sie zusammenhaltender Verschlusskörper herzustellen sind, der alle Tubenköpfe umfasst.A multi-chamber tube with at least two chambers and a tube head with the number of compartments that can be closed Withdrawal openings separated from a cluster of at least two produced tube tubes arranged parallel to each other with an all Tube tubes have a common rounded outer circumference, is known from WO 94/19251. This tube consists of several separately manufactured individual tubes, each with one Tube head with a dispensing opening through a holding it together Closure body at one end and a seal at the other end be held together. This multi-chamber tube is complex to produce because several separate tubes and an additional one holding them together Closure body are to be produced, which includes all tube heads.

Aufgabe der Erfindung ist es, ein einfacheres und preisgünstigeres Verfahren zu bieten, wobei die hergestellte Mehrkammertube dennoch ein schönes Aussehen aufweist.The object of the invention is a simpler and cheaper process to offer, but the multi-chamber tube produced still has a beautiful appearance.

Diese Aufgabe wird durch eine Mehrkammertube mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.This task is carried out by a multi-chamber tube with the characteristic Features of claim 1 solved.

Vorteilhafte Ausführungen der Erfindung sind den Unteransprüchen zu entnehmen. Advantageous embodiments of the invention can be found in the subclaims.

Nachstehend wird die Erfindung anhand eines Ausführungsbeispiels unter Bezug auf Zeichnungen näher erläutert. Es zeigt:

Fig. 1
eine Zweikammertube im teilweisen Querschnitt,
Fig. 2
eine Draufsicht auf die Mehrkammertube.
The invention is explained in more detail below using an exemplary embodiment with reference to drawings. It shows:
Fig. 1
a two-chamber tube in partial cross-section,
Fig. 2
a top view of the multi-chamber tube.

Die in Fig. 1 gezeigte Zweikammertube 1 als Beispiel für Mehrkammertuben besteht aus zwei Rohrkörpern 2, 2', die nach einem beliebigen bekannten Verfahren mit einer überlappenden Längsnaht hergestellt sind, beispielsweise nach dem aus der DE-C- 31 05 146 bekannten Verfahren.The two-chamber tube 1 shown in FIG. 1 exists as an example for multi-chamber tubes of two tubular bodies 2, 2 ', which by any known method an overlapping longitudinal seam are produced, for example after the from the DE-C-31 05 146 known methods.

Die hergestellten Rohrkörper 2, 2' - gegebenenfalls abgelängt - werden dann an zwei Stellen axial geritzt oder gekerbt, wobei die Kerblinien 3 die Stellen im Rohrkörper 2, 2' markieren, an denen ein Abbiegen aus der hergestellten runden Form zur Bildung eines im Ausführungsbeispiel D-förmigen Rohrkörpers 2, 2' erfolgen soll. Die Kerblinien 3 sind so auszuführen, daß, wenn beide Rohrkörper 2, 2' zu einem D geformt sind mit ihren jeweils geraden Abschnitten aneinander gelegt werden, ein gerundeter Außenumfang erzeugt wird. Der Außenumfang kann z. B. kreisrund oder auch beliebig oval hergestellt werden. Die Art der Rundung wird bei D-förmigen Rohrkörpern 2, 2' vom Abstand der beiden Kerblinien 3 vorgegeben.The tubular body 2, 2 'produced - if necessary cut to length - are then on two Places axially scored or notched, the score lines 3 the places in the tubular body 2, Mark 2 'at which a turn from the round shape made to form of a D-shaped tubular body 2, 2 'in the exemplary embodiment. The Notch lines 3 are to be designed so that when both tubular bodies 2, 2 'form a D are formed with their respective straight sections placed one against the other rounded outer circumference is generated. The outer circumference can e.g. B. circular or can also be made in any oval shape. The type of rounding is D-shaped Pipe bodies 2, 2 'specified by the distance between the two score lines 3.

Die Kerblinien 3 werden vorzugsweise durch radial zustellbare drehbar gelagerte Kerbscheiben durchgeführt, wobei jede Verletzung des Materialaufbaus vermieden werden muß.The score lines 3 are preferably rotatably supported by radially adjustable Notched disks carried out, avoiding any damage to the material structure must become.

Danach werden die gekerbten Rohrkörper 2, 2' - vorzugsweise ausgerichtet - durch eine Formplatte geschoben, in der eine bleibende Veränderung der Form erfolgt, beispielsweise für eine Zweikammertube eine im Querschnitt D-förmige Form, deren Kanten, die den geraden Abschnitt begrenzen, durch die beiden Kerblinien 3 vorgegeben sind.The notched tubular bodies 2, 2 'are then - preferably aligned - through a molded plate in which there is a permanent change in shape, For example, for a two-chamber tube, a cross-sectionally D-shaped shape Edges that delimit the straight section through the two score lines 3 are specified.

Dann werden die D-förmigen Rohrkörper 2, 2' einzeln je einem entsprechend gestalteten Dorn zugeführt, die vorzugsweise zum Aufziehen der Rohrkörper beabstandet voneinander anordenbar und relativ zueinander beweglich sind. Beim Aufziehen der Rohrkörper 2, 2' auf die D-förmigen Dorne ist darauf zu achten, daß die Nahtbereiche jeder Tube getrennt voneinander, d. h. beabstandet zueinander auf den geraden Abschnitten der D-förmigen Rohrkörper 2, 2' liegen, damit keine sich überlappenden Vierfachlagen beim Zusammenführen der Rohrkörper 2, 2' zu einer Mehrkammertube vorliegen. Die zum Aufziehen der Rohrkörper 2, 2' beabstandeten oder verschwenkten D-förmigen Dorne werden zusammengeführt und gemeinsam einer Verpreßstation zugeführt. In der Verpreßstation wird mittels einer oder gegebenenfalls mehreren Materialschmelzeportionen der Tubenkopf 4 mit den getrennten Ausgabeöffnungen 5 und/oder gegebenenfalls auch mehreren Trennwänden 6 hergestellt. Gleichzeitig erfolgt eine Verbindung mit den beiden Rohrkörpern 2, 2' sowohl am Außenrand als auch an der Trennwand 6, so daß im Ergebnis zwei vollständig voneinander getrennte Kammern 7, 7' entstehen. Beim Aufschieben verbleibt zwischen den beiden Rohrkörperenden, die der Verpreßstation zugeführt werden, ein Restspalt in Höhe der Schulterkontur, der mit dem Hohlraum zur Bildung der Kopfschulter in Verbindung steht und dadurch sich beim Preßvorgang mit Materialschmelze füllt. Hierdurch werden die Ränderenden der Rohrkörper 2, 2' umflossen und sind beim Aushärten fest miteinander verbunden.Then the D-shaped tubular bodies 2, 2 'are each individually one designed mandrel, which is preferably used to wind the tubular body spaced apart and movable relative to each other. At the Pulling the tubular body 2, 2 'onto the D-shaped mandrels is important to ensure that the seam areas of each tube separately, d. H. spaced apart from each other the straight sections of the D-shaped tubular body 2, 2 'lie so that none overlapping quadruple layers when merging the tubular body 2, 2 'into one Multi-chamber tube available. The spaced for pulling the tubular body 2, 2 ' or pivoted D-shaped mandrels are brought together and together fed to a pressing station. In the pressing station, one or optionally several portions of material melt the tube head 4 with the separate dispensing openings 5 and / or possibly several Partitions 6 made. At the same time, a connection is established with the two Tubular bodies 2, 2 'both on the outer edge and on the partition 6, so that in The result is two completely separate chambers 7, 7 '. At the Sliding remains between the two tube body ends, which the Injection station are fed, a residual gap at the level of the shoulder contour with connects to the cavity to form the head shoulder and thereby fills with molten material during the pressing process. This will make the edge ends the tubular body 2, 2 'flow around and are firmly together during curing connected.

Wie oben dargelegt werden bei dem geschilderten Vorgang auch die sich gegenüberliegenden oberen Enden der Rohrkörper 2, 2' fest miteinander verbunden. Zusätzlich kann entlang aller eine Mehrkammertube bildenden Rohrkörper im beliebigen Bereich der aneinander anliegenden - vorzugsweise geraden - Abschnitte der jeweiligen Mehrkammertuben eine Verbindung beispielsweise durch einen Anschmelz- oder Anklebvorgang erzielt werden, wodurch z. B. auch die dem Tubenkopf 4 entgegengesetzten Enden der Rohrkörper 2, 2' fest miteinander verbunden werden können.As explained above, the process described also applies to the opposite upper ends of the tubular body 2, 2 'firmly connected. In addition, along all tube bodies forming a multi-chamber tube in the any area of the adjacent - preferably straight - sections of the respective multi-chamber tubes, for example, by a connection Melting or gluing process can be achieved, whereby z. B. also the Tube head 4 opposite ends of the tubular body 2, 2 'firmly together can be connected.

Erforderlichenfalls kann auch erst jetzt ein Ablängen der fertigen Mehrkammertuben z. B. durch ein Rotationsmesser erfolgen.If necessary, the finished multi-chamber tubes can only be cut to length z. B. done by a rotary knife.
