"Tubenförmiger Behälter, Verfahren zur Herstellung dieses Behälters und Vorrichtung zur Durchführung eines solchen"Tubular container, method of making same Container and device for carrying out such

Verfahrens"Procedure "

Die vorliegende Erfindung bezieht sich auf einen tubenformigen Behälter aus einem mehrschichtigen Folienblatt mit mindestens drei Schichten, wovon die beiden Außenlagen thermoplastisch sind.The present invention relates to a tubular Container made from a multilayer film sheet with at least three layers, the two outer layers of which are thermoplastic are.

Darüber hinaus betrifft die Erfindung ein Verfahren zur Herstellung eines solchen tubenformigen Behälters sowie eine Vorrichtung zur Durchführung dieses Verfahrens.In addition, the invention relates to a method for Production of such a tubular container and a device for carrying out this method.

Die bisher bekannten tubenformigen Behälter, die durch Einrollen eines mehrschichtigen Folienblattes hergestellt werden, weisen den Nachteil auf, daß die Schnittkante des die Tuben bildenden Folienblattes gegen direkten Kontakt zwischen dem darin enthaltenen Gut und den Schichten des Folienblattes, insbesondere bei Folienblättern mit einer Mittellage aus Aluminiumfolie, in keiner Weise geschützt wird.The previously known tubular container, which by rolling a multilayer film sheet are produced, have the disadvantage that the cut edge of the Foil sheet forming tubes against direct contact between the material contained therein and the layers of the foil sheet, especially in the case of foil sheets with a central layer made of aluminum foil, is not protected in any way.

Zur Behebung dieses Nachteils hat man die Verwendung eines Streifens vorgeschlagen, der allerdings einer vorherigen, sehr speziellen Vorarbeit bedarf, wobi das z.B. aus Metall bestehende Folienblattozwischen zwei aufzuwalzende thermoplastische Schutzstreifen eingefaßt werden muß, welche diese Innenlage aus Metall weit übergreifen. Dieses VerfahrenTo remedy this disadvantage, it has been proposed to use a strip, but to replace a previous one, very special preparatory work is required, e.g. made of metal existing foil sheet between two thermoplastic materials to be rolled Protective strips must be bordered, which extend far beyond this inner layer made of metal. This method

409830/0878 /2 409830/0878 / 2

ist kostspielig und kompliziert durchzuführen, da Walzanlagen hoher Präzision hierzu erforderlich sind.is costly and complicated to carry out because of the rolling mills high precision are required for this.

Aufgabe der vorliegenden Erfindung ist die Behebung der Nachteile bekannter tubenförmiger Behälter und Verfahren zu deren Herstellung unter Verwendung mehrschichtiger Folienblätter ohne komplizierte Vorarbeiten, wobei die Schnittkante während der Formung des ELienblattes zu einer Tube mit einer schützenden Schicht versehbar ist.The object of the present invention is to remedy the disadvantages known tubular container and method for their Manufactured using multilayer film sheets without complicated preparatory work, with the cut edge can be provided with a protective layer during the formation of the sheet of paper into a tube.

Zur Lösung dieser Aufgabe sieht die Erfindung einen tubenf örmigffl. Behälter aus einem mehrschichtigen Folienblatt wie eingangs beschrieben vor, wobei die innere thermoplastische Schicht die Schnittkante der z.B. aus Metall bestehenden Mittellage überlagert und dieser überlagernde Übertritt auf der Innenseite größer ist als der Übertritt der thermoplastischen Schicht auf der Außenseite.To solve this problem, the invention provides a tubular shape. Container made from a multi-layer film sheet such as initially described, the inner thermoplastic layer being the cut edge of the middle layer made of metal, for example superimposed and this superimposed transition on the inside is greater than the transition of the thermoplastic Layer on the outside.

Das mehrschichtige Folienblätt, welches nach einer möglichen Ausführungsform der Erfindung aus einer zwischen zwei Lagen aus thermoplastischem Material eingebetteten Aluminiumfolie besteht, wird um einen Aufziehdorn gerollt, so daß sich seine beiden Seitenränder oberhalb einer heizbaren Zone überlappen. Die überlappenden Ränder setzt man mittels eines Preßwerkzeuges über deren gesamte Länge unter Preßdruck.The multi-layer film sheet, which after a possible Embodiment of the invention made of an aluminum foil embedded between two layers of thermoplastic material exists, is rolled around a mandrel so that its two side edges overlap above a heatable zone. The overlapping edges are put under pressure by means of a pressing tool over their entire length.

Bei diesem Preßwerkzeug handelt es sich um ein haubenartiges Obergesenk mit im wesentlichen konka· ven Querschnitt, welches auf seiner Arbeitsfläche einen Belag aus hartem Material aufweist. z.B.. aus Blech, welcher auf mindestens einer Seite mit elastischem Material beschichtet ist.This pressing tool is a hood-like upper die with an essentially concave cross-section, which has a covering made of hard material on its work surface. E.g. made of sheet metal, which on at least one side with elastic material is coated.

Zur leichteran Aufbringung auf die überlappenden Seitenränder des Folienblattes ist dieses Obergesenk um eine querverlaufende Mittelachse schwenkbar.For easier application to the overlapping side edges of the sheet of film, this upper die is around a transverse Swiveling central axis.

Die heizbare Zone des Aufziehdorns, oberhalb welcher sich dieThe heatable zone of the mandrel, above which the

/5/ 5

Seitenränder desFolienblattes überlappen, kann vorteilhafterweise mit mindestens einer überhöhten Längsprofilxerung ausgebildet sein, um ein leichtes Exndringen in die thermoplastische Masse des Folienblattes zu gestatten.Overlapping side edges of the film sheet can advantageously be designed with at least one elevated longitudinal profile in order to easily exude the thermoplastic Allow mass of the foil sheet.

Diese Heizzone besteht vorzugsweise aus einem elektrischen Widerstand in Streifenform. Die Erhitzung läßt sich auch über ein fließfähiges Medium bewerkstelligen, z.B. mittels unter dieser Zone hindnrchgeführter Heißluft.This heating zone preferably consists of an electrical resistor in the form of a strip. The heating can also by means of a flowable medium, e.g. by means of hot air guided under this zone.

Die überlappenden Seitenränder werden über dieser Heizzone erhitzt, und unter der doppelten Einwir^kung von Druck und Wärme wird ein Teil des Materials der thermoplastischen Schichten an den beiden überlappenden Rändern beiderseits des Überlappungsbereiches verdrängt, wobei diese verdrängte Masse des Thermoplaste die Schnittkante der Metallfolie am inneren Hand überlagernd umfließt und um diese eine Art Isolierung und andrerseits einen Wulst bildet, der den unmittelbar an den äußeren Hand des Folienblättes angrenzenden Bereich gegen das Obergesenk preßt und damit diesen Bereich des Folienblattes in die Höhe des äußeren Randes drängt.The overlapping side edges are heated above this heating zone, and under the double action of pressure and Heat becomes part of the material of the thermoplastic layers at the two overlapping edges on either side of the overlap area, this displaced mass of the thermoplastic being the cut edge of the metal foil flows around overlying the inner hand and forms a kind of insulation around it and, on the other hand, a bulge that forms the immediate on the outer hand of the film sheet presses the area adjacent to the upper die and thus this area of the foil sheet pushes up to the level of the outer edge.

Da das öbergesenk kälter ist als die Innenfläche des Folienblattes, ist der überlagernde Übertritt der thermoplastisc ten Schicht über den äußeren Rand des die Tube bildenden Folienblatfces geringer als auf der Innenseite.Since the upper downside is colder than the inner surface of the foil sheet, is the overlapping transition of the thermoplastic th layer over the outer edge of the tube forming Foil sheets less than on the inside.

Nach einer weiteren vorteilhaften Ausführungsform ist die Heizzone wulstartig ausgebildet zum leichteren Exndringen in das durch Erhitzung erweichende Material, so daß dadurch auf jeder Seite der Verbindungsstelle auf der Innenwand der Tube Längswülste aus durch die doppelte Wirkung von Ereßdruck und Erhitzung verdrängter thermoplastischer Masse entstehen. According to a further advantageous embodiment, the Heating zone designed in the form of a bead for easier exuding into the material which is softened by heating, so that this on each side of the junction on the inner wall of the tube, longitudinal bulges are made by the double action of erectile pressure and heating of the displaced thermoplastic mass.

Der so erhaltene Tubenkörper wird mit einem Hals stück versehen. The tube body thus obtained is provided with a neck piece.

Das Material dieses Halsstückes wird durch. Formgießen oder durch Reibschweißen stirnseitig am Tubenkörper befestigt, um die Schnittkante der Metallfolie schützend zu überlagern. Diese Anformung des Halsstückes erfolgt unter Drehung des Halsstückes gegen ein Ereßwerkzeug mit einer an die Endlippe des Tubenkörpers angrenzenden ringförmigen Ausnehmung. Diese Anformung des Halsstückes gewährleistet den Torteil, daß die Schnittkante der Metallfolie gegen die Einwirkung von auf dem Halsstück nach Gebrauch derTube haftenden Produkten geschützt bleibt.The material of this neck piece is through. Molding or Attached to the end of the tube body by friction welding in order to protect the cut edge of the metal foil. This shaping of the neck piece is carried out by rotating the neck piece against an erecting tool with one on the end lip of the tube body adjacent annular recess. This molding of the neck ensures the gate part, that the cut edge of the metal foil protects against the effects of products adhering to the neck piece after use of the tube remains protected.

Das Einrollen des Folienblattes um den Aufziehdorn erfolgt vorzugsweise über zwei seitliche Andruckvorrichtung^ welche die Seitenränder des Folienblattes nacheinander um den Dorn schlagen.The rolling of the sheet of film around the mandrel is preferably carried out using two lateral pressure devices fold the side edges of the foil sheet one after the other around the mandrel.
