Description

Die Erfindung betrifft eine Tube, bestehend aus einem Tubenkörper aus einem Laminat mit metallischer Sperrschicht, einem Tubenkopf aus einem Kunststoff und einer auf der Außenfläche der Tubenkopfschulter angeordneten Rondelle aus einem Laminat mit metallischer Sperrschicht, wobei der Tubenkopf den Tubenkörper . untergreift, und Verfahren zu deren Herstellung.The invention relates to a tube consisting of a tube body made of a laminate with a metallic barrier layer, a tube head made of a plastic and a rondelle made of a laminate with a metallic barrier layer arranged on the outer surface of the tube head shoulder, the tube head forming the tube body. engages, and processes for their manufacture.

Eine derartige Tube ist aus der Fig. 4 und 5 und der zugehörigen Beschreibung der DE-A-2 628 014 bekannt.Such a tube is known from FIGS. 4 and 5 and the associated description of DE-A-2 628 014.

Hierbei überlappt der Rand des Rohrkörpers die auf dem abgestuften Tubenkopf angeordnete Rondelle. Die Rondelle weist ebenfalls eine Abstufung auf, die der Form der Tubenkopfschulter angepaßt ist. Hierbei hat die Rondelle die Funktion eines Verbindungskörpers und weist eine wesentlich dickere Metallschicht als der Rohrkörper auf. Hierdurch wird erreicht, daß beim vorgesehenen induktiven Verschweißen die benötigte Frequenz auf diese dickere Metallschicht so abgestimmt wird, daß sich die Metallschicht im Tubenrohr praktisch nicht erwärmt. Die metallische Sperrschicht in der Rondelle dient auch dazu, die Gasdichtheit im Tubenkopf zu erhöhen.The edge of the tubular body overlaps the rondelle arranged on the stepped tube head. The rondelle also has a gradation that is adapted to the shape of the tube head shoulder. The rondelle has the function of a connecting body and has a much thicker metal layer than the tubular body. This ensures that the required frequency is matched to this thicker metal layer in the intended inductive welding so that the metal layer in the tube tube practically does not heat up. The metallic barrier layer in the rondelle also serves to increase the gas tightness in the tube head.

Da sich Rondelle und Tubenrohr überlappen, liegen zwischen ihren beiden als Barriere dienenden Metallschichten zwei Kunststoffschichten, die keine Gasdichtheit aufweisen, so daß hierdurch eine gewisse Undichtheit entsteht.Since the rondelle and tube tube overlap, there are two plastic layers between their two metal layers serving as a barrier, which have no gas tightness, so that this creates a certain amount of leakage.

Bei Tuben kommt es aber auch darauf an, daß sie ein schönes Aussehen aufweisen. Um eine einigermaßen schöne Tubenschulter zu erhalten, muß der Tubenkopf und damit auch die Rondelle abgestuft sein, damit das Tubenrohr so angeformt werden kann, daß keine unschöne Aufwölbung entsteht, wie sie sich zwangsläufig ausbildet, wenn eine Schicht von einer anderen überlappt wird. Daraus folgt aber auch, daß die gestufte Rondelle eine stärkere Metallschicht haben muß als der Rohrkörper, da nur dann der zur Herstellung notwendige Formziehvorgang durchgeführt werden kann. Dies bedeutet aber, daß ein wesentlich teureres Laminat verwendet werden muß, was allein schon die Herstellungskosten der Tube erhöht. Außerdem lassen sich Farbtönungsunterschiede zwischen Rohrkörper und Rondellenmaterial nicht vermeiden, und da sie im Überlappungsbereich auf der Tubenschulter zwangsläufig nebeneinander liegen, verschlechtert dies das schöne Aussehen, da sich auf der Tubenschulter zwei Farbringe abzeichnen, eventuell noch ein dritter im Ausdünnungsbereich des Materials des Rohrkörpers, das das freie Ende der Metallschicht versiegeln muß.With tubes it is also important that they have a beautiful appearance. In order to obtain a reasonably beautiful tube shoulder, the tube head and thus also the rondelle must be graduated so that the tube can be molded in such a way that there is no unsightly bulge, which inevitably develops when one layer is overlapped by another. However, it also follows that the stepped rondelle must have a thicker metal layer than the tubular body, since only then can the shape-drawing process necessary for the production be carried out. However, this means that a much more expensive laminate must be used, which alone increases the production costs of the tube. In addition, color differences between the tube body and the rondelle material cannot be avoided, and since they are necessarily next to each other in the overlap area on the tube shoulder, this worsens the beautiful appearance, since two color rings appear on the tube shoulder, possibly a third in the thinning area of the material of the tube body, that must seal the free end of the metal layer.

Aus der DE-A-1 486 193 ist eine ähnliche Tube bekannt, wobei jedoch die Rondelle an der Innenfläche des hier gerundeten Tubenkopfes derart angeordnet ist, daß der Rand des Rohrkörpers auf dem Außenrand des Kopfes untergriffen wird, wobei der Außenrand der Rondelle nach oben in den Kopf zurückgebogen sein kann. Hierbei verbleibt zwischen der Metallschicht de'3 Rohrkörpers und der der Rondelle immer ein Abstand, der nur von Kunststoff ausgefüllt ist, so daß die Gasdichtheit im Tubenkopfbereich verschlechtert ist.A similar tube is known from DE-A-1 486 193, but the rondelle is arranged on the inner surface of the rounded tube head in such a way that the edge of the tubular body is gripped under on the outer edge of the head, the outer edge of the rondelle being upward can be bent back into the head. In this case, there is always a distance between the metal layer of the tube body and that of the rondelle, which is only filled with plastic, so that the gas tightness in the tube head area is deteriorated.

Aus der CH-A-500 878 ist eine Tube bekannt, bei der der obere Rand des Tubenrohrkörpers auf der Außenfläche der Schulter des Tubenkopfes eingelegt wird, was komplizierte Maschinen erfordert und die Herstellung verlängert; anschließend wird dann ein konischer Schulterring aufgelegt und schließlich wird alles unter Druck und Erwärmung, insbesondere durch Induktion, verschweißt.From CH-A-500 878 a tube is known in which the upper edge of the tube body is placed on the outer surface of the shoulder of the tube head, which requires complicated machines and lengthens the manufacture; then a conical shoulder ring is put on and finally everything is welded under pressure and heating, especially by induction.

All diesen Tuben ist gemeinsam, daß für die Rondelle wegen ihrer Größe und Gestalt viel Material erforderlich ist, auch wegen des anfallenden Abfalls, das sich zudem noch vom Material des Rohrkörpers unterscheidet. Bei der Tube nach dem CH-Patent wird zudem noch Material der Rohrkörper für das Einlegen in Falten auf dem Tubenkopf benötigt.All these tubes have in common that a lot of material is required for the rondelle because of its size and shape, also because of the waste that arises, which also differs from the material of the tubular body. In the case of the tube according to the CH patent, material of the tube body is also required for insertion in folds on the tube head.

Aufgabe der Erfindung ist es, eine Tube der eingangs genannten Art und Verfahren zu ihrer Herstellung anzugeben, durch die es möglich ist, Material einzusparen, die Gasdichtheit und das Aussehen im Kopfbereich zu verbessern.The object of the invention is to provide a tube of the type mentioned and methods for its manufacture, by means of which it is possible to save material, to improve the gas tightness and the appearance in the head area.

Diese Aufgabe wird durch eine Tube mit den im Anspruch 1 wiedergegebenen Merkmalen gelöst.This object is achieved by a tube with the features set out in claim 1.

Durch das Anliegen auf Stoß von Rondelle und Rohrkörper ist die Rondelle im Durchmesser kleiner, wodurch Material eingespart wird. Die Rondelle muß keine Stufe aufweisen, so daß eine stärkere Metallschicht nicht notwendig ist. Durch die Stoßverbindung liegen die sperrenden Metallschichten von Rondelle und Rohrkörper so dicht beieinander, selbst wenn sie nicht gleich stark ausgebildet sind, daß eine nahezu optimale Gasdichtheit gewährleistet ist. Es sind auch keine Materialausdünnungen zum Versiegeln freiliegender Metallschichtenden notwendig. Es besteht zwischen Rohrkörper und Rondelle ein schöner gleichmäßiger, in einer Ebene liegender Übergang.Due to the abutment of the rondelle and the tubular body, the rondelle is smaller in diameter, which saves material. The rondelle does not have to have a step so that a thicker metal layer is not necessary. Due to the butt joint, the blocking metal layers of the rondelle and the tubular body are so close together, even if they are not of the same strength, that an almost optimal gas tightness is guaranteed. There is also no need for material thinning to seal exposed metal layer ends. There is a nice, even transition lying on one level between the tubular body and the rondelle.

Wenn gemäß einer vorteilhaften Ausgestaltung für Rondelle und Rohrkörper das gleiche Laminatmaterial verwendet wird, entfallen zusätzliche Kosten und es ist eine absolute Farbgleichheit gewährleistet.If, according to an advantageous embodiment, the same laminate material is used for the rondelle and tubular body, additional costs are eliminated and absolute color uniformity is ensured.

Der Anspruch 3 gibt ein vorteilhaftes Verfahren zur Herstellung der erfindungsgemäßen Tube an.Claim 3 specifies an advantageous method for producing the tube according to the invention.

Nachstehend wird die Erfindung anhand von Ausführungsbeispielen unter Bezug auf Zeichnungen näher erläutert. Es zeigt

  • Fig. 1 den Kopfbereich einer erfindungsgemäßen Tube mit abgestufter Schulter des Tubenkopfes im Schnitt,
  • Fig. 2 den Kopfbereich einer erfindungsgemäßen Tube mit abgerundeter Schulter des Tubenkopfes im Schnitt.
The invention is explained in more detail below using exemplary embodiments with reference to drawings. It shows
  • 1 the head area of a tube according to the invention with a stepped shoulder of the tube head in section,
  • Fig. 2 shows the head area of a tube according to the invention with a rounded shoulder of the tube head in the cut.

Eine Tube enthält einen Rohrkörper 1, einen Tubenkopf 2 und eine konische ringförmige Rondelle 3. Der Rohrkörper 1 und die Rondelle 3 sind aus einem Laminat mit eingeschlossener Metallschicht hergestellt. Vorzugsweise bestehen beide aus dem gleichen Material. Der Tubenkopf 2 besteht aus einem Kunststoff und weist im Randbereich seiner Schulter 4 eine abgestufte (Fig. 1) oder abgerundete (Fig. 2) Form auf. Die Rondelle 3 wird auf die Schulter 4 aufgelegt und der Rohrkörper 1 so auf den Tubenkopf 2 aufgeschoben, daß beim Anformen seine Schnittkante 5 an der äußeren Randkante 6 auf Stoß anliegt. Es kann auch zuerst der Rohrkörper positioniert werden und dann die Rondelle 3 eingelegt werden. Der Rohrkörper 1 oder die Rondelle 3 können, bevor das jeweils andere Teil positioniert wird, schon mit dem Tubenkopf 2 verbunden sein.A tube contains a tubular body 1, a tube head 2 and a conical annular rondelle 3. The tubular body 1 and the rondelle 3 are made of a laminate with an enclosed metal layer. Preferably both are made of the same material. The tube head 2 consists of a plastic and has a stepped (FIG. 1) or rounded (FIG. 2) shape in the edge region of its shoulder 4. The rondelle 3 is placed on the shoulder 4 and the tubular body 1 is pushed onto the tube head 2 in such a way that its cut edge 5 abuts against the outer edge 6 when molded. The tubular body can also be positioned first and then the rondelle 3 can be inserted. The tubular body 1 or the rondelle 3 can already be connected to the tube head 2 before the other part is positioned.

Die gebildete Stoßstelle zwischen der Schnittkante 5 und der Randkante 6 wird vorzugsweise durch Wärmeübertragung, gegebenenfalls unter Druckaufbringung, versiegelt; dies kann separat oder auch im Zusammenhang mit der Verbindung des Rohrkörpers 1 und der Rondelle 3 mit dem Tubenkopf 2 erfolgen. Das Verbinden des Rohrkörpers 1 und der Rondelle 3 mit dem Tubenkopf 2 und das Versiegeln der Stoßverbindung kann durch Induktion, Ultraschall, Strahlungswärme (z. B. Infrarot) oder durch Kombination dieser Möglichkeiten vorgenommen werden.The joint formed between the cutting edge 5 and the edge 6 is preferably sealed by heat transfer, possibly under pressure; this can be done separately or in connection with the connection of the tubular body 1 and the rondelle 3 to the tube head 2. The connection of the tubular body 1 and the rondelle 3 with the tube head 2 and the sealing of the butt joint can be carried out by induction, ultrasound, radiant heat (e.g. infrared) or by a combination of these possibilities.

Es besteht auch die Möglichkeit, den Rohrkörper 1 zunächst mit der Rondelle 3 auf Stoß zu fügen und dann mit einem gespritzten Tubenkopf 2 zu versehen oder auch diesen Tubenkopf 2 direkt einzuformen oder einzuspritzen, wobei gleichzeitig die Versiegelung der Stoßverbindung erfolgt.There is also the possibility of first joining the tubular body 1 with the rondelle 3 and then providing it with an injection-molded tube head 2 or also molding or injecting this tube head 2 directly, with the butt joint being sealed at the same time.
