Definitions

  • the invention relates to a multi-component cartridge having the features of the preamble of claim 1.
  • Such cartridges are used for storing and dispensing flowable, for example, pasty masses such as adhesives or sealants.
  • flowable for example, pasty masses such as adhesives or sealants.
  • the cartridges are used in Auspresspistolen or the like., Which displace a piston in a Auspressraum in the cartridge and thereby squeeze out the mass contained in the cartridge.
  • the publication DE 10 2005 017 599 A1 discloses a two-component cartridge which is divided into two chambers in which two components of a flowable mass are kept separate from each other.
  • the known cartridge has a pliable film which is inserted by means of cores in an injection mold so that it forms two tubes with a common partition.
  • the film is overmolded with a plastic, which forms the cartridge.
  • the film bonds to the cartridge sprayed around it, the partition wall of the bag formed by the film also forming in the cartridge a partition dividing the cartridge into two chambers which are filled with the two components.
  • the two components of the flowable mass can be pressed with a conventional Einpresspistole for one-component cartridges, the partition is separated during displacement of the piston from the cartridge.
  • a disadvantage of the known two-component cartridge is the pliable partition which ensures neither fixed chamber volumes nor a constant Auspressreheat the two components. In addition, the production of the known cartridge is expensive.
  • the object of the invention is to propose an improved multi-component cartridge.
  • the multi-component cartridge according to the invention has at least one partition which is stretched in the cartridge and subdivides the cartridge into chambers.
  • a partition divides the cartridge into two chambers, more than one partition allows more than two chambers.
  • squeezing the displaced in the cartridge piston separates the partition from the cartridge.
  • the invention with a more or less rigid partition wall is possible, it is in itself intended for a pliable foil as a partition, because a clamping of a rigid partition wall is not necessary and a rigid partition of the displacement of the piston opposes a high resistance, the the pressing difficult.
  • the partition extends in a longitudinal direction of the preferably cylindrical cartridge, the partition is stretched in a chordal plane of the cartridge and divides the cartridge into chambers with constant cross-sections over the length.
  • the partition is stretched in a transverse direction of the cartridge, a tension in the longitudinal direction is possible.
  • An embodiment of the invention provides a film bag containing a component of the flowable mass.
  • An area of a wall of the film bag is stretched as a partition wall in the cartridge.
  • a multi-chamber foil bag is possible, which has a plurality of, preferably tubular chambers with a common partition or common partitions, which are stretched in the cartridge.
  • a foil pouch which has a region which forms the dividing wall stretched in the cartridge, can be connected to the cartridge, flat or even along lines or line-shaped strips, where the dividing wall abuts against the cartridge.
  • a Embodiment of the invention provides at least one, preferably two outwardly projecting strips of the film bag, which are connected to the cartridge.
  • the film bag can be folded into one or two duplicated strips. Another possibility is to produce the film bag from two films, which are connected in strips to the bag, wherein the connected film strips form the outwardly projecting strips of the film bag.
  • An embodiment of the invention provides a rigid head piece with an outlet, for example a tubular nozzle, for the component of the flowable mass contained in the film bag.
  • the foil bag can be glued or welded to the head piece, for example.
  • This embodiment of the invention allows a pliable and thus thin-walled foil bag and a rigid head piece.
  • "Stiff" in the sense of the invention does not mean absolutely rigid, but includes an elasticity of the head piece. The head should be so stiff that it does not deform so much, especially during the pressing of the mass, that the squeezing is impaired.
  • two-component cartridge 1 consists of plastic and is cylindrical tube-shaped. It has at one end, which is referred to here as the front end, a perforated disk-shaped end wall 2 with a tubular outlet 3.
  • the outlet 3 has a thread 4 for screwing on a cover, not shown, a nozzle, not shown, or a static mixer, not shown.
  • a likewise tubular outlet 5 of a foil bag 6 located in the cartridge 1 is arranged.
  • the outlet 5 is one of double-walled, so hollow head piece 11 from which has the shape of a circle segment in front view.
  • the head piece 11 is located on an inner side of the end wall 2, it is welded to the film bag 6 or otherwise connected.
  • the head 11 including its outlet 5 is made of a rigid plastic, it retains its shape.
  • the film bag 6 is composed of two pliable films 7, 8 and is, as in FIG. 2 can be seen, produced on a core 9, whose cross section has a congruent to the head piece 11 segmental circle shape.
  • the two films 7, 8 are the same length and different widths.
  • One film 7 is placed in the form of a cylindrical shell around a cylindrical surface of the core 9, the other on a flat side of the core 9.
  • the films 7, 8 are so wide that they protrude over longitudinal edges of the core 9, the protruding strips 10 of the films. 7 , 8 are glued together, welded or otherwise connected.
  • the protruding strips 10 of the films 7, 8 form outwardly projecting strips 10 of the film bag 6, which form the two interconnected films 7, 8.
  • the strips 10 extend in the longitudinal direction of the film bag 6 along longitudinal edges of the core 9.
  • the head 11 which is open at its outlet 5 opposite side, placed at one end on the core 9 and with transverse edges of the the film bag 6 forming films 7, 8 glued, welded or otherwise connected.
  • the film bag 6 located on the core 9 is introduced from the rear into the cartridge 1 with the head piece 11, so that the outlet 5 of the film bag 6 concentrically in the outlet 3 of the cartridge 1, the head piece 11 on an inner side of the end wall 2 of the cartridge 1 and the wider film 7 of the film bag 6 are cylindrical shell-shaped on an inner side of the cartridge 1.
  • the outwardly projecting from the film bag 6 strips 10 are mounted on the inside of the cartridge 1, for example, glued or welded. Conceivable and possible is a welding from the outside, for example, with ultrasound.
  • the film bag 6 is thus produced on the core 9 and the strips 10 are secured in the cartridge 1, that the film 8 is stretched on the flat side of the core 9 and remains tensioned after pulling out of the core 9.
  • the film 8 forms a partition 12, which is stretched in a longitudinal plane of the cartridge 1 and the cartridge 1 divided into two chambers. One of the two chambers has a circular segment-shaped cross section, the other chamber takes the remaining cross section one.
  • the two chambers of the cartridge 1 are filled with two components of a flowable mass, for example with a binder and a hardener of a resin or adhesive.
  • the rear, the head piece 11 far end of the film bag 6 can be compressed after filling and sealed, for example by gluing, welding or with a clip (not shown).
  • the film 8 of the film bag 6, which forms the partition wall 12 of the cartridge 1 is tensioned in the cartridge 1, it is possible to successively fill the two components in the two chambers of the cartridge 1. Due to their tension, the partition wall 12 bulges only slightly and the volumes of the two chambers hardly change.
  • the cartridge 1 is pressed in the same way as is known from single-component cartridges which are not subdivided into chambers: the cartridge 1 is inserted into an ejection gun or the like which has a piston which is displaceable into the cartridge 1 (not shown).
  • the piston displaces the components from the two chambers of the cartridge 1 through the two outlets 3, 5, i. the piston, not shown, presses the components out of the cartridge 1.
  • the piston With a screwed onto the thread 4 of the outlet 3 of the cartridge 1, not shown static mixer, the two components can be mixed.
  • the piston not shown, separates the foil bag 6 from the cartridge 1 and folds or crumples it on its front wall 2 facing the front side together.
  • the piston separates the film bag 6 on its displacement length from the inside of the cartridge 1. Since the formed by a film 8 of the film bag 6 partition 12 in the Cartridge 1 is stretched, the ratio of the extruded amounts of the two components is constant, it corresponds to the cross-sectional ratio of the two chambers of the cartridge 1. It can be for each component of the stored in the cartridge 1, flowable mass a film bag 6 is inserted into the cartridge 1 and to be fixed in it (not shown). This basically applies to more than two components. Portions of the foil pouches 6, which form a dividing wall 12, are clamped in the cartridge 1 in the tendon planes of the cartridge 1, as described.
  • the outwardly projecting from the film bag 6 strips 10 are not mandatory for the attachment of the film bag 6 in the cartridge 1 is necessary.
  • a seamless, in particular tubeless foil bag can be used (not shown).
  • On a seamless foil bag can run longitudinally, outward from Foil bag protruding strip for attachment of the film bag in the cartridge 1 are produced by longitudinal folds of the film bag, which form strip-shaped duplications of the wall of the film bag. The doublings forming the strips are glued, welded or otherwise connected.
  • FIG. 3 shows a two-chamber film bag 6. It consists of a film 7, which is placed around two cores 9, 13.
  • the one core 9 has the circular segment shape of in FIG. 2 shown core 9, the other core 13 complements the core 9 to a cylindrical shape.
  • the film 7 is guided between the flat surfaces of the two cores 9, 13 and then placed around both cores 9, 13 around.
  • the flat surfaces of the cores 9, 13 lie with the interposition of the film 7 to each other.
  • On one side of the cores 9, 13 projects a strip 14 of the film 7, which is bonded, welded or otherwise connected to form the two-chamber film bag 6 with the part of the film 7 lying around the cores 9, 13.
  • a longitudinal edge strip 15 of the film 7 overlaps the part of the film 7 projecting between the two cores 9, 13 and around the cores 9, 13 and is likewise joined by gluing, welding or in some other way.
  • the two-chamber foil bag 6 can be produced outside the cartridge 1. It is conceivable manufacture in the cartridge 1, when the film 7 in the manner described between the cores 9, 13 is passed and placed around them and is introduced with the cores 9, 13 in the cartridge 1.
  • the gluing of the strip 14 and the overlapping longitudinal edge strip 15 on the opposite side of the cores 9, 13 can for example be carried out by ultrasonic welding from the outside through the cartridge 1, whereby at the same time the two strips 14, 15 are welded to the cartridge 1, so that the between the cores 9, 13 located part of the film 7, which forms the partition wall 12, is stretched in the cartridge 1.
  • the two-chamber foil bag 6 off FIG. 3 has no outwardly projecting strips for its attachment in the cartridge 1, which is not excluded.
  • FIG. 4 shows a film bag 6 produced from a film 7.
  • the film 7 is placed around a core 9, which again has a circular segment-shaped cross section.
  • the film 7 is placed around the cylindrical and flat surface of the core 9, so that along a longitudinal edge of the core 9 two strips 14 protrude, which are welded together, glued or connected in any other way.
  • the strips 14 form a laterally projecting strip 10, with which the film bag 6 is mounted in the cartridge 1.
  • the film bag 6 from FIG. 4 no outward strip, he is there connected to the inside of the cartridge 1 fitting with her.
