Description

Die Erfindung betrifft ein Verfahren zum Herstellen eines Zweikammerdruckbehälters aus einem Aussenbehälter und einem deformierbaren Innenbehälter zur Aufnahme eines Produktes, wobei Aussenbehälter und Innenbehälter zumindest in einem Öffnungsbereich miteinander verbunden werden.The invention relates to a method for producing a Two-chamber pressure container consisting of an outer container and one deformable inner container for receiving a product, wherein Outer container and inner container at least in one opening area be connected to each other.

Stand der TechnikState of the art

Derartige Zweikammerdruckbehälter sind in vielfältiger Form und Ausführung bekannt und auf dem Markt. Nur beispielhaft wird auf die DE-OS 2 227 509 verwiesen. Such two-chamber pressure vessels are of various shapes and designs known and on the market. DE-OS 2 227 509 only serves as an example directed.

Aus der EP-A 0 326 052 ist beispielsweise eine Zweikammer-Druckpackung bekannt, bei der nach dem Verbinden von Aussenhülle und Innenkörper eine Haftvermittlerschicht diesen Öffnungsbereich gemeinsam zu einem Bördelrand verbindet.EP-A 0 326 052, for example, describes a two-chamber pressure pack known in which a after connecting the outer shell and inner body Adhesion promoter layer this opening area together to form a flange edge combines.

Aus der DE 44 13 331 A1 ist ein Verfahren bekannt, bei dem nach dem Verbinden von Aussenhülle und Innenkörper durch die Haftvermittlerschicht und vor dem Umlegen zu einem Bördelrand ein Ring von der Aussenhülle und dem Innenkörper entfernt wird.From DE 44 13 331 A1 a method is known in which according to Connecting the outer shell and the inner body through the adhesive layer and a ring from the outer casing and a flanged edge before folding the inner body is removed.

Aufgabetask

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren der o.g. Art zu schaffen, bei dem die Haftung zwischen Aussenbehälter und Innenbehälter wesentlich verbessert wird.The present invention has for its object to provide a method of the above. To create the way in which the liability between the outer container and Inner container is significantly improved.

Lösung der AufgabeSolution of the task

Zur Lösung dieser Aufgabe führt, dass der Aussenbehälter und/oder Innenbehälter zumindest teilweise im Verbindungsbereich mit einer Struktur versehen werden.To solve this problem, the outer container and / or Inner container at least partially in the connection area with a structure be provided.

Die Struktur ermöglicht es, dass der Haftvermittler in die Struktur eindringt und sich so verankert. Dadurch wird gewährleistet, dass der Innenbehälter nur unter erheblichen Kraftaufwand aus dem Aussenbehälter gezogen werden kann.The structure enables the coupling agent to penetrate into the structure and anchored so This ensures that the inner container is only under considerable effort can be drawn from the outer container.

In einem bevorzugten Ausführungsbeispiel werden Aussenbehälter und/oder Innenbehälter im Verbindungsbereich gebürstet. Das Bürsten ist eine einfache Methode zum Einbringen einer Riefenstruktur. Diese Riefenstruktur ist ungeordnet, was die Verankerungsmöglichkeiten nochmals verbessert. Allerdings soll auch die Einbringung eines geordneten Riefen- oder Rillenstruktur vom Erfindungsgedanken umfasst werden. In a preferred embodiment, outer containers and / or Brushed inner container in the connection area. Brushing is easy Method of inserting a groove structure. This grooved structure is disorderly, which further improves the anchoring options. However, the introduction of an orderly score or Groove structure to be covered by the inventive concept.

Bevorzugt sollen die Riefen- oder Rillenstruktur um eine Behälterachse herum in Umfangsrichtung verlaufen. Auf diese Weise bilden die Riefen oder Rillen eine Widerlagerstruktur, was bei einem achsparallelen Verlauf nicht gegeben wäre. The groove or groove structure should preferably be around a container axis run in the circumferential direction. In this way, the striations or grooves form an abutment structure, which is not the case with an axially parallel course would.

Figurenbeschreibungfigure description

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung; diese zeigt in

  • Figur 1 einen Querschnitt durch einen Zweikammerdruckbehälter;
  • Figur 2 einen Längsschnitt durch einen Teil eines Aussenbehälters;
  • Figur 3 eine Draufsicht auf einen Teil eines Innenbehälters.
    • Further advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawing; this shows in
  • Figure 1 shows a cross section through a two-chamber pressure vessel;
  • FIG. 2 shows a longitudinal section through part of an outer container;
  • Figure 3 is a plan view of part of an inner container.

    • Gemäss Figur 1 weist ein Zweikammerdruckbehälter im wesentlichen einen Aussenbehälter 1 und einen Innenbehälter 2 auf. Aussenbehälter 1 und Innenbehälter 2 sind in einem oberen Bereich miteinander verbunden. Dieser Verbindungsbereich ist mit 3 gekennzeichnet. Die Verbindung kann beispielsweise durch Kleben erfolgen. Zu einem späteren Zeitpunkt wird ein Zwischenraum 4 zwischen Innenbehälter 2 und Aussenbehälter 1 mit einem Druckmedium gefüllt. Ferner wird der Innenbehälter 2 mit einem Produkt gefüllt, welches dann durch ein aufzusetzendes Ventil ausgebracht werden kann. Derartige Zweikammerdruckbehälter sind beispielsweise in der EP-A-0 326 052 und der DE 44 13 331 beschrieben.According to FIG. 1, a two-chamber pressure vessel essentially has one Outer container 1 and an inner container 2. Outer container 1 and Inner containers 2 are connected to one another in an upper region. This Connection area is marked with 3. The connection can for example by gluing. At a later date, a Intermediate space 4 between inner container 2 and outer container 1 with one Media filled. Furthermore, the inner container 2 is filled with a product which can then be applied through a valve to be attached. Such two-chamber pressure vessels are described, for example, in EP-A-0 326 052 and DE 44 13 331.

    Gemäss der vorliegenden Erfindung ist der Verbindungsbereich 3 des Aussenbehälters 1 gebürstet, so dass in ihm eine Riefen- bzw. Rillenstruktur 5 eingeformt ist. Diese Riefenstruktur 5 verläuft in Umfangsrichtung auf einer Innenwand 6 des Aussenbehälters 1 um seine Längsachse A herum.According to the present invention, the connection area 3 of the The outer container 1 is brushed, so that a groove or groove structure 5 is formed in it is molded. This groove structure 5 runs in the circumferential direction on a Inner wall 6 of the outer container 1 around its longitudinal axis A.

    Gemäss Figur 3 weist auch der Innenbehälter 2 auf seiner Aussenfläche 7 im Verbindungsbereich 3 eine Riefen- bzw. Rillenstruktur 8 auf, wobei auch hier die Riefenstruktur 8 in Umfangsrichtung einer Längsachse B des Innenbehälters 2 herum verläuft. According to FIG. 3, the inner container 2 also has on its outer surface 7 in Connection area 3 on a groove or groove structure 8, here too the groove structure 8 in the circumferential direction of a longitudinal axis B of the Inner container 2 runs around.

    Die Funktionsweise der vorliegenden Erfindung ist folgende:The operation of the present invention is as follows:

    Der mit der Riefenstruktur 8 versehene Innenbehälter 2 wird in den Aussenbehälter 1 eingesetzt. Wobei der Verbindungsbereich 3 beider Behälter mit einem Haftvermittler versehen wird. Der Haftvermittler dringt selbstverständlich auch in die Riefenstruktur 5 bzw. 8 ein, so dass sich eine feste Verbindung im Verbindungsbereich 3 zwischen Innenbehälter 2 und Aussenbehälter 1 ergibt. Durch die Anordnung der Riefenstruktur um die Längsachsen A und B herum ergibt sich ein Widerlager gegen ein Bewegen des Innenbehälters 2 in Achsrichtung B.The inner container 2 provided with the groove structure 8 is in the Outer container 1 used. The connection area 3 of both containers is provided with an adhesion promoter. The promoter penetrates of course also in the groove structure 5 or 8, so that a firm connection in the connection area 3 between inner container 2 and Outer container 1 results. By arranging the groove structure around the Longitudinal axes A and B result in an abutment against movement of the inner container 2 in the axial direction B.

    In einem bevorzugten Ausführungsbeispiel soll die Riefenstruktur 5 und/oder 8 durch Bürsten eingeformt werden. In a preferred embodiment, the groove structure 5 and / or 8 can be formed by brushing.
