Tube besteht im Wesentlichen aus einer als Formteil aus Kunststoff, beispielsweise aus PE oder PP hergestel lten Tubenschultern 2, welche bei der dargestel lten Ausführungsform den 4 and 5 representations similar to Figure 3 in further embodiments of the invention. The generally designated 1 in the figures tube packaging or tube consists essentially of a plastic as a molding of plastic, such as PE or PP Hergestel Lten tube shoulders 2, which in the illustrated embodiment, the dar

Tubenschulterabschnitt 2.2 mit dem anschl ießenden ringförmigen, die Tubenachse TA umschließenden Randbereiche 2.3 bildet. Der Tubennippel 2.1 weist die übl iche Tube shoulder section 2.2 with the subsequent annular, the tube axis TA enclosing edge regions 2.3 forms. The tube nipple 2.1 shows the usual

Tubenöffnung 3 auf, die durch eine nicht dargestel lte Verschlusskappe verschl ießbar ist. Tube opening 3, which is schliess by a not dargestel Lte cap.

Die Tube 1 besteht weiterhin aus dem Tubenkörper 5, der bzw. dessen Tubenwand 6 aus einem Flachmaterial 7 durch Einrol len dieses Materials und durch Verbinden der einander benachbarten Flachmaterialrandbereich hergestellt ist. Das Flachmaterial 7 ist bei der dargestellten Ausführungsform von zwei Flachmaterialschichten oder -bahnen 8.1 und 8.2 gebildet, die jeweils gleiche Breite B aufweisen und in geeigneter Weise, beispielsweise durch Verschweißen und/oder Verkleben derart miteinander verbunden sind, dass an einem Längsrand 7.1 des Flachmaterials 7 die Materialbahn 8.1 randseitig mit einem Randabschnitt 8.1 .1 über den Rand der Materialbahn 8.2 und am anderen Längsrand 7.2 des Flachmaterials 7 umgekehrt die Materialbahn 8.2 randseitig mit einem Randabschnitt 8.2.1 über den entsprechenden Rand der Materialbahn 8.1 vorsteht. Hierdurch ist das Flachmaterial 7 an seinen Längsrändern 7.1 und 7.2 jeweils entgegengesetzt stufenförmig ausgebildet. An den Randabschnitten 8.1 .1 und 8.2.1 beträgt die Dicke des Flachmaterials 7 nur 1/2d, wobei d die Dicke des Flachmaterials außerhalb dieser Randbereiche 8.1 .1 und 8.2.1 ist. The tube 1 further consists of the tube body 5, the or the tube wall 6 made of a flat material 7 by Einrol len this material and by connecting the adjacent flat edge material area is made. The flat material 7 is formed in the illustrated embodiment of two flat material layers or tracks 8.1 and 8.2, each having the same width B and are connected in a suitable manner, for example by welding and / or gluing together so that at a longitudinal edge of the flat material 7th the material web 8.1 on the edge side with an edge section 8.1 .1 over the edge of the material web 8.2 and at the other longitudinal edge 7.2 of the sheet 7, the web of material 8.2 protrudes marginally with an edge section 8.2.1 on the corresponding edge of the web 8.1. As a result, the flat material 7 is formed at its longitudinal edges 7.1 and 7.2 each opposite stepped. At the edge sections 8.1 .1 and 8.2.1, the thickness of the flat material 7 is only 1 / 2d, where d is the thickness of the flat material outside these edge areas 8.1 .1 and 8.2.1.

Zur Bildung der Tubenkörperwandungen 6 wird das Flachmaterial 7 beispielsweise kontinuierl ich um wenigstens eine Achse parallel zur Längsrichtung des bahnförmigen Flachmaterials 7 kontinuierl ich eingerollt, sodass sich die Randbereiche 8.1 .1 und 8.2.1 überlappen. An dieser Überlappung erfolgt dann eine goßflächige überlappende Verbindung 9 der beiden Längsränder 7.1 und 7.2 insbesondere an den sich in Umfangsrichtung erstreckenden Flächen der Randabschnitte 8.1 .1 und 8.2.1 , beispielsweise durch To form the tube body walls 6, the flat material 7 is, for example, continuously rolled around at least one axis parallel to the longitudinal direction of the sheet-like sheet material 7, so that the edge regions 8.1 .1 and 8.2.1 overlap. At this overlap then takes place a pouring overlapping connection 9 of the two longitudinal edges 7.1 and 7.2 in particular at the circumferentially extending surfaces of the edge portions 8.1 .1 and 8.2.1, for example by

Verschweißen, sofern die einander überlappenden Flächen aus einem verschweißbaren Material ien bestehen, oder durch Verkleben, insbesondere auch dann wenn wenigstens eine der einander überlappenden Flächen aus einem nicht verschweißbaren Material besteht. Nach dem Verbinden ist aus dem Flachmaterial 7 ein schlauchförmiges Material erhalten, aus dem dann jeweils der Tubenkörper 5 bzw. dessen Wandung 6 mit der benötigten Länge abgetrennt wird. Anschl ießen wird die jeweil ige Tubenwand 6 mit dem Tubennippel 2 im Bereich des beispielsweise von der Tubenwand 6 umschlossenen Welding, if the overlapping surfaces of a weldable material ien, or by gluing, especially if at least one of the overlapping surfaces consists of a non-weldable material. After joining, a tubular material is obtained from the flat material 7, from which then respectively the tube body 5 or its wall 6 with the required length is separated off. The respective tube wall 6 with the Tube nipple 2 in the region of, for example, enclosed by the tube wall 6

Randbereichs 2.3 verbunden, z. B. durch Verschweißen oder Verkleben. Edge area 2.3 connected, z. B. by welding or gluing.

Durch die sich überlappenden Randbereiche 8.1 .1 und 8.2.1 ist eine großflächige und damit sehr feste, aber auch dichte Verbindung des Flachmaterials 7 an seinen Längsseiten 7.1 und 7.2 nach dem Einrollen mögl ich. Sofern es notwenig ist, kann die Tubenwandung 6 an der Außenseite und/oder Innenseite mit einer die überlappende Verbindung 9 überdeckenden Beschichtung versehen sein, wie dies in der Figur 3 mit der Beschichtung 10 angedeutet ist. Die Herstel lung des Flachmaterials 7 erfolgt also durch randseitig versetztes Due to the overlapping edge regions 8.1 .1 and 8.2.1 is a large-scale and thus very strong, but also dense connection of the sheet 7 on its longitudinal sides 7.1 and 7.2 after rolling I mögl. If necessary, the tube wall 6 may be provided on the outside and / or inside with a coating covering the overlapping connection 9, as indicated in FIG. 3 by the coating 10. The manufacture ment of the sheet 7 is thus offset by edge

Zusammenführen der beiden Materialbahnen 8.1 und 8.2 mit anschl ießendem vol lflächigen Verkleben oder Verschweißen dieser Materialbahnen an i hren einander berührenden Oberflächenseiten. Vorstehend wurde davon ausgegangen, dass das Flachmaterial 7 von zwei  Merging the two webs of material 8.1 and 8.2 with subsequent continuous surface bonding or welding of these webs to the surfaces contacting one another. It was assumed above that the sheet 7 of two

Flachmaterialbahnen 8.1 und 8.2 gebildet ist. In der Praxis besteht zumindest eine dieser Flachmaterialbahnen 8.1 bzw. 8.2 aus mehreren Einzelschichten, wie dies in der Figur 4 für die Materialbahn 8.1 mit den verschiedenen Schichten 1 1 angedeutet ist. Die Schichten 1 1 sind dann entsprechend ihrer Funktion, beispielsweise als Tragschicht, Sperrschicht, Dekorschicht, Deckschicht usw. aus unterschiedlichen Werkstoff gefertigt und wiederum durch Verschweißen und/oder Verkleben flächig miteinander zu der Materialbahn 8.1 verbunden sind. Die wenigstens eine, als Sperrschicht wirkende Schicht 1 1 besteht dabei bevorzugt aus Metall, z.B. Aluminium, während die übrigen Schichten 1 1 bevorzugt solche aus Kunststoff sind. Die Schichtfolge ist so gewählt, dass nach dem Einrol len des  Flat material webs 8.1 and 8.2 is formed. In practice, at least one of these flat material webs 8.1 or 8.2 consists of a plurality of individual layers, as indicated in FIG. 4 for the material web 8.1 with the various layers 11. The layers 1 1 are then according to their function, for example as a support layer, barrier layer, decorative layer, cover layer, etc. made of different materials and in turn are connected by welding and / or gluing surface to each other to the web of material 8.1. The at least one barrier layer 1 1 is preferably made of metal, e.g. Aluminum, while the remaining layers 1 1 are preferably made of plastic. The layer sequence is chosen so that after Einrol len of

Flachmaterials 7a an der Verbindung 9 die Randbereiche 8.1 .1 und 8.2.1 flächig mit solchen Schichten 1 1 einander anl iegen, die ein festes und dichtes Verbinden z.B. durch Flat material 7a at the connection 9, the edge regions 8.1 .1 and 8.2.1 lie flat with such layers 1 1 to each other, which results in a firm and tight joining, e.g. by

Verschweißen oder Verkleben ermöglichen, beispielsweise mit Schichten 1 1 aus Kunststoff, z.B. (PE). Die metall ische Sperrschicht 1 1 ist beispielsweise in der Materialbahn 8.1 zwischen einer die Außenfläche des Tubenkörpers 5 bildenden, beispielsweise bedruckten Deck- oder Dekorschicht 1 1 , z.B. hinterdruckten Deck- oder Dekorschicht 1 1 und einer weiter innen liegenden Kunststoffschicht 1 1 vorgesehen, und zwar derart, dass die als metal l ische Sperrschicht ausgeführte Schicht 1 1 nicht nur für die gewünschte Sperrwirkung sorgt, sondern zugleich auch als metal l ischer, glänzender H intergrund den optischen Eindruck der Tubenausstattung wesentl ich verbessert. Diejenigen Schichten 1 1 , die nicht unmittelbar die flächige Verbindung im Bereich der Verbindung 9 bewirken, schließen jeweils mit ihren eigenen Randbereichen stumpf aneinander an. Dies gilt insbesondere auch für die als metallische Sperrschicht ausgebildete Schicht 1 1 . Allow welding or bonding, for example, with layers 1 1 of plastic, eg (PE). The metallic barrier layer 1 1, for example, in the web 8.1 between the outer surface of the tube body 5 forming, for example printed cover or decorative layer 1 1, for example, back-printed cover or decorative layer 1 1 and a further inner plastic layer 1 1 is provided, namely in such a way that the layer 1 1 designed as a metal barrier layer not only provides the desired blocking effect, but at the same time substantially improves the visual impression of the tube equipment as a metallic, glossy background. Those layers 1 1, which do not directly cause the surface connection in the region of the compound 9, each butt with their own edge regions to each other. This also applies in particular to the layer 11 formed as a metallic barrier layer.

Vorstehend wurde davon ausgegangen, dass das Flachmaterial 7 bzw. 7a im Bereich seiner Längsränder 7.1 und 7.2 nur eine einzige Stufe aufweist, was durch das randseitig versetzte Zusammenführen und Verbinden zweier Materialbahnen 8.1 und 8.2 erreicht wird. It has been assumed above that the flat material 7 or 7a has only a single step in the region of its longitudinal edges 7.1 and 7.2, which is achieved by the merging and joining of two material webs 8. 1 and 8.

Entsprechend der Figur 5 besteht auch die Möglichkeit, durch randseitig versetztes According to the figure 5, it is also possible, by edge offset

Zusammenführen von mehr als zwei Materialbahnen, beispielsweise durch randseitig versetztes Zusammenführen von drei Materialbahnen 8.1 - 8.3 an jedem Längsrand des Flachmaterials 7b insgesamt zwei Stufen zu erzeugen, an denen dann nach dem Einrollen des Flachmaterials 7a eine zweifache flächige überlappende Verbindung 9 erfolgt. Die Erfindung wurde voranstehend an Ausführungsbespielen beschrieben. Es versteht sich, dass zahlreiche Änderungen sowie Abwandlungen möglich sind, ohne dass dadurch der der Erfindung zugrundeliegende Erfindungsgedanke verlassen wird. Merging of more than two webs, for example, by edge offset merging of three webs 8.1 - 8.3 at each longitudinal edge of the sheet 7b to produce a total of two stages at which then takes place after rolling of the sheet 7a a two-fold overlapping compound 9. The invention has been described above in exemplary embodiments. It is understood that numerous changes and modifications are possible without thereby departing from the inventive concept underlying the invention.
