Die Erfindung betrifft einen Tubenbehälter mit mehrschichtiger Wand, wobei mindestens eine Schicht aus thermoplastischem Material und eine metallische Zone vorhanden sind.The invention relates to a tube container with a multi-layer wall, there being at least one layer made of thermoplastic material and a metal zone. Tuben dieser Art, die eine mehrschichtige Wand besitzen mit einer undurchlässigen Metallschicht, die zwischen Lagen von Kunststoff oder Papier eingebettet ist, sind allgemein bekannt. Es wird hierfür auf die beiden Schweizer Patentschriften Nrn. 452 879 sowie 468 914 verwiesen, wo auch die entsprechenden Herstellungsverfahren offenbart sind. Diese Tuben enthalten eine relativ dicke Aluminiumschicht in Form einer Folie von z.B. 18 |xm Stärke, die einen totalen Lichtschutz bietet, das Hinausdiffundieren von Bestandteilen der Füllgüter sowie das Hineindiffundieren von Sauerstoff verhindert.Tubes of this type, having a multilayer wall with an impermeable metal layer sandwiched between layers of plastic or paper, are well known. In this regard, reference is made to the two Swiss patent specifications Nos. 452 879 and 468 914, where the corresponding production processes are also disclosed. These tubes contain a relatively thick aluminum layer in the form of a foil, e.g. 18 µm thick, which offers total light protection and prevents components of the filling goods from diffusing out and oxygen from diffusing in. Zur Herstellung der Tuben wird eine zunächst bandförmige Mehrschichtfolie zu einem Rohr geformt, wobei die miteinander zu verbindenden Folienränder sich überlappen. Die Naht wird anschliessend geschweisst.To produce the tubes, a multi-layer film in the form of a strip is initially formed into a tube, with the film edges to be joined overlapping. The seam is then welded. Dabei tritt bei der üblichen thermischen Schweissung von bekannten Laminaten mit Metallfolie mittels der Verfahren gemäss CH-PS 452879 und 468 914 die Bildung von Querfalten am Längsfalz im Tubeninnern auf. Diese Querfalten sind qualitätsmindernd, indem die die Metallfolie schützende Kunststoffschicht im Bereich solcher Querfalten relativ dünn ist und dadurch die Beständigkeit gegen aggressive Füllgüter herabgesetzt wird. Es kann sogar der Fall auftreten, dass das Aluminium bei einer Querfalte gar nicht mit Kunststoff bedeckt ist, was bei sauren oder alkalischen Füllgütern zur Korrosion des Aluminiums und zum Versagen der Packung führen kann. Ferner führt die Metallschicht zu einer im Vergleich mit reinen Kunststofftuben verschlechterten Verschweissbarkeit des Tubenendes bei Schweissen durch thermische Strahlung oder durch Heizbackenschweissung.With the usual thermal welding of known laminates with metal foil by means of the processes according to CH-PS 452879 and 468 914, the formation of transverse folds occurs on the longitudinal fold inside the tube. These transverse folds reduce the quality, in that the plastic layer protecting the metal foil is relatively thin in the area of such transverse folds, thereby reducing the resistance to aggressive filling goods. It can even happen that the aluminum is not covered with plastic at all in the case of a transverse fold, which can lead to corrosion of the aluminum and failure of the packing in the case of acidic or alkaline filling goods. Furthermore, the metal layer leads to poorer weldability of the tube end in comparison with pure plastic tubes when welding by thermal radiation or by heated jaw welding. Es stellt sich demnach die Aufgabe, einen Tubenbehälter der eingangs genannten Art bereitzustellen, dessen Wand die erforderlichen Sperreingenschaften besitzt, ohne dass dies die erwähnten Nachteile nach sich zieht.The object is therefore to provide a tube container of the type mentioned at the outset, the wall of which has the required blocking properties without this entailing the disadvantages mentioned. Diese Aufgabe wird überraschenderweise dadurch gelöst, dass die metallische Zone als Aufdampfschicht ausgebildet ist, die eine Dicke von weniger als 1 |im aufweist. Durch den Ersatz der normalerweise mehr als 15 |im dicken Metallfolie durch die viel dünnere Aufdampfschicht kann die Bildung von Querfalten am Längsfalz bei der Tubenherstellung vermindert und die Schweissbarkeit insgesamt verbessert werden, wobei die Sperreigenschaften erhalten bleiben.Surprisingly, this object is achieved in that the metallic zone is in the form of a vapor-deposited layer which has a thickness of less than 1 μm. Replacing the normally more than 15 µm thick metal foil with the much thinner vapor deposition layer can reduce longitudinal fold transverse creases during tube manufacture and improve overall weldability while maintaining barrier properties. Die Aufdampfschicht ist vorzugsweise auf einer Trägerfolie aus thermoplastischem Material oder aus Papier aufgebracht.The vapor-deposited layer is preferably applied to a carrier film made of thermoplastic material or paper. Einseitig oder beidseitig der metallisierten Trägerfolie ist bei einer vorteilhaften Ausführung der Erfindung je mindestens eine thermoplastische Kaschierfolie vorgesehen.In an advantageous embodiment of the invention, at least one thermoplastic laminating film is provided on one or both sides of the metalized carrier film. Nachfolgend wird anhand der einzigen Figur ein Ausführungsbeispiel der Erfindung näher beschrieben.An exemplary embodiment of the invention is described in more detail below with reference to the single FIGURE. Die Figur zeigt den Wandaufbau eines fertigen Tubenbehälters als Wandausschnitt ausserhalb der Naht. Die Darstellung ist stark vergrössert und die relativen Wandstärken sind nicht massstabge-recht gezeichnet. Der Wandaufbau ist nicht symmetrisch, weshalb Innen- und Aussenseite markiert sind.The figure shows the wall structure of a finished tube container as a wall section outside the seam. The illustration is greatly enlarged and the relative wall thicknesses are not drawn to scale. The wall structure is not symmetrical, which is why the inside and outside are marked. Auf einer Trägerfolie 6 ist eine weniger als 1 um dicke Metallschicht 5 angeordnet. Diese wird durch Bedampfung der PETP-Trägerfolie (Polyethylenglykolterephthalat) mit Aluminium im Vakuum hergestellt.A metal layer 5 less than 1 μm thick is arranged on a carrier foil 6 . This is produced by vapor-depositing the PETP carrier film (polyethylene glycol terephthalate) with aluminum in a vacuum. Die metallisierte Trägerfolie 5, 6 wird beidseitig mit einer Kaschierschicht 4, 7 auf Polyurethanbasis versehen, welche die Haftung der Kaschierfolien 3, 8 an der metallisierten Trägerfolie sicherstellt. Die Kaschierfolien 3, 8 bestehen aus LDPE (= Polyäthylen niedriger Dichte), wobei die innere Kaschierfolie 8 zum Schutze der Metallschicht 5 gegen Angriffe des Füllgutes dient und die äussere Kaschierfolie 3 dazu dient, eine gute Haftung für eine ummantelnde Deckschicht 2 aus LDPE zu gewährleisten.The metallized carrier film 5, 6 is provided on both sides with a laminating layer 4, 7 based on polyurethane, which ensures the adhesion of the laminating films 3, 8 to the metallized carrier film. The laminating foils 3, 8 consist of LDPE (=low-density polyethylene), with the inner laminating foil 8 serving to protect the metal layer 5 against attacks by the filling material and the outer laminating foil 3 serving to ensure good adhesion for a covering cover layer 2 made of LDPE . Diese Deckschicht 2 wird über das vorgeformte Rohr, bestehend aus den Schichten 3 bis 8, nahtlose extrudiert.This covering layer 2 is seamlessly extruded over the preformed pipe, consisting of layers 3 to 8. Mit Ausnahme der genannten Abweichungen erfolgt die Herstellung des Tubenbehälters auf an sich bekannte Art, wobei auf die vorstehenden Publikationen verwiesen werden kann.With the exception of the deviations mentioned, the tube container is manufactured in a manner known per se, reference being made to the above publications. Die oben erläuterte bevorzugte Materialwahl ist an die jeweiligen Bedürfnisse, insbesondere den Anwendungsbereich des Tubenbehälters anpassbar. So kann die Trägerfolie 6 für die Metallschicht aus Papier oder aus einem geeigneten thermoplastischen Kunststoff der Gruppe Polyester, Polyäthylen, Polypropylen, Polyamid, bestehen.The preferred choice of material explained above can be adapted to the respective needs, in particular to the area of application of the tube container. Thus, the carrier foil 6 for the metal layer can be made of paper or of a suitable thermoplastic material from the group consisting of polyester, polyethylene, polypropylene, and polyamide. Desgleichen kann auch für die Kaschierfolien 3 und 8 ein thermoplastischer Kunststoff aus der Gruppe Polypropylen, Polyvinylchlorid, Polyamid, Polyester verwendet werden.A thermoplastic material from the group consisting of polypropylene, polyvinyl chloride, polyamide and polyester can likewise also be used for the laminating films 3 and 8 . Da sich die Sperreigenschaften der aufgedampfen Metallschicht von weniger als 1 |im Dicke als ausreichend erwiesen haben, kann der Aufdampfvorgang in herkömmlicher Weise erfolgen. Dabei wird die Trägerfolie 6 z.B. in einem Hochvakuumkessel (1,3 x 10~2 bis 1,3 x 10~3 Pa) mit Metall beschichtet, das durch elektrisches Erhitzen verdampft wird.Since the barrier properties of the vapor-deposited metal layer of less than 1 μm thickness have proven to be sufficient, the vapor deposition process can be carried out in a conventional manner. The carrier film 6 is coated with metal, for example in a high-vacuum vessel (1.3 x 10 -2 to 1.3 x 10 -3 Pa), which is vaporized by electrical heating. Der erfindungsgemäss aufgebaute Tubenbehälter weist gegenüber bekannten Behältern mit Metalleinlage den Vorteil auf, dass eine faltenfreie Verbindungsnaht herstellbar ist, wodurch sich die Behältereigenschaften wesentlich verbessern. Ferner ist das Tubenende durch thermische Strahlung oder durch Heizbackenschweissen leichter verschweissbar als bei den bekannten, eine Metallschicht enthaltenden Tuben.Compared to known containers with a metal insert, the tube container constructed according to the invention has the advantage that a crease-free connecting seam can be produced, as a result of which the container properties are significantly improved. Furthermore, the end of the tube can be welded more easily by thermal radiation or by heated jaw welding than in the case of the known tubes containing a metal layer. 55 1010 1515 2020 2525 3030 3535 4040 4545 5050 5555 6060 6565 RR 1 Blatt Zeichnung1 sheet of drawing
