  • US 3,323,682 shows two versions of one Disposable cartridge packaging with several chambers, e.g. For the components of two-component adhesive systems, which has two foldable compartments in its interior, the chambers for has the component-forming containers.
  • This Cartridge contains the individual components in the desired proportions and in each other captive form and can also be found in commercially available Hand presses are processed, however, it causes a Multiples of the packaging waste of tubular bag packaging same content.
  • EP 0754633A2 describes multi-chamber tubular bag packaging known in which the components of a Two-component adhesive in contrast to the previously mentioned Versions compact and captive in separate chambers within a multi-chamber tubular bag be accommodated.

  • the adapter designed to remove substances from Multi-chamber tubular bags, in particular made of Double-chamber tubular bags, in such a way that the Components removed from the chambers in the adapter be performed separately.
  • the adapter points to this at least two channels for the promotion of substances contained in the bag chambers by this through and is designed such that the Inner walls of the passage channels at least at Application of the substances contained in the bag chambers come into direct contact with these substances.
  • the passage channels are at their entry through a footbridge separated from each other, which has a recess in its center for receiving a Closure clips of a multi-chamber tubular bag to be arranged on the adapter having.
  • the substances removed from the chambers are in the adapter preferably in an essentially axial direction Direction, based on the axis of the one to be connected to the adapter Multi-chamber tubular bag, guided and in brought to exit in the axial direction.

It is also an advantage if the outlet openings are also essentially in are arranged in a central area of the adapter. Especially in applications where the adapter is connected downstream Dispensing nozzles are used in this way a slim arrangement with essentially axial Extension, whereby an application of the to be discharged Guts simplified even in tight spaces becomes.
  • the adapter advantageously has means to open the tubular bag chambers, creating a targeted opening as a result of puncturing or cutting the outer skin of the tubular bag ensured can be.
  • these means are fixed in the adapter and are preferably configured such that opening the Bag chambers of the tubular bag to the passage channels the adapter during the first targeted pressurization of the tubular bag provided with the adapter takes place or when attaching and pressing the adapter on the tubular bag.

  • Embodiments in which a essentially opening at least two at the same time Bag compartments for at least two passages can be ensured. This is done with advantage through a mechanical coupling of movable opening means. Especially when used in context with multi-component adhesive systems and the adapter downstream mixing elements, it is the largest Importance that all components from the first moment provided in the correct proportions because there is only a well-defined mix the components to the desired adhesive properties leads.

  • the adapter is preferably made from a Made of plastic, especially from a plastic with low adhesive strength compared to multi-component adhesives. This has the advantage of being a mechanical one Removing hardened adhesive residues on the Exit of the adapter is simplified. It is too preferred if the adapter is made by injection molding will, since this will reduce the manufacturing costs large quantities are particularly low.
