Definitions

  • the invention relates to a multi-chamber cartridge for multicomponent plastic compositions such as silicones, adhesives and the like with axially successively arranged chambers for receiving the components according to the preamble of claim 1.
  • the two chambers each associated with its own piston, which are operated together to express the two components, arranged in a cylindrical cartridge tube one behind the other.
  • the first chamber is formed between the cartridge tube and a concentric inner tube arranged therein, which extends over only about half the length of the cartridge tube.
  • This annular chamber is closed by a rear-inserted annular piston.
  • the second, axially behind the chamber is formed by a forwardly extended to a cup piston, the cup wall rests against the inner wall of the cartridge tube.
  • the Rear chamber also contains a central pin projecting from the piston forward, which dips into the inner tube of the front chamber when advancing the rear piston.
  • the rear chamber is delimited by a radial wall adjoining the end of the inner tube of the front chamber, which rests against the inner wall of the inner chamber of the rear chamber.
  • a two-chamber cartridge with the combination of features of the preamble of claim 1 is from the unpublished, but prioritized senior document EP 1 634 654 A1 , Fig. 8 there known.
  • the double-walled insert forms at its front end a transversely divided mouthpiece, one outlet channel of which communicates with the inner sub-chamber in the front part of the cartridge tube interior, and the other part of which is in communication with the annular outer sub-chamber in the front part of the cartridge tube interior.
  • the annular space between the spaced-apart tube walls of the double-walled insert connects the annular outer sub-chamber in the front part of the cartridge tube interior with the chamber formed in the rear part of the cartridge tube.
  • the invention has for its object to provide a multi-chamber cartridge with axially one behind the other chambers, in which a simple filling of each of the chambers on a standard filling plant is possible, and which also makes it possible to use the cartridge as needed as a three-chamber cartridge.
  • the front chamber is formed by the front part of the interior of the cartridge tube
  • the rear chamber is formed by the interior of a cup, which is inserted into the rear part of the cartridge tube only after filling and closing with a piston. Therefore, in the arrangement according to the invention both chambers can be filled separately on a standard filling line with the respective component and then closed by means of a piston before the cup forming the rear chamber is inserted into the cartridge tube.
  • the multi-chamber cartridge consists of a rear open cartridge tube 1 with a front end wall 2 and a molded mouthpiece 3, a double wall insert 4 concentrically inserted in the front part of the cartridge tube 1 with a front end wall 5 and a molded inner mouthpiece 6, concentric in Mouthpiece 3 is arranged, a piston assembly of an annular piston 7 and a central piston 8 for closing the front part of the cartridge formed front component chamber K1, further from a to be used in the rear part of the cartridge tube 1 and a rear chamber K2 forming cup 9 with a rear cup bottom 10, an integrally formed central hollow pin 11 and a front open cup end occlusive annular piston 12th
  • FIG. 1 shows the state of the multi-chamber cartridge at the end of production, where the component chambers K1 and K2 formed in the front part of the cartridge tube 1 and the cup 9 are already filled and closed with the respective piston 7, 8 and 12, wherein the cartridge tube 1 and cup. 9 but still separate.
  • the cup 9 is inserted into the rear part of the cartridge tube, and the multi-chamber cartridge is ready for use, ie the squeezing of the cartridge can begin.
  • FIG. 1 At first, however, are still related to FIG. 1 to explain some details of the cartridge assembly.
  • a double-walled insert 4 is inserted in the front part of the cartridge tube 1.
  • This forms a concentric double-walled inner tube within the front part of the cartridge tube and thus divides the front part of the interior of the cartridge tube 1 into an annular outer partial chamber K1a and an inner partial chamber K1b.
  • the two sub-chambers are filled with the same first material component, they are not in communication with each other. At the same time, however, this also creates the option of using the cartridge according to the invention as a three-chamber cartridge for three material components.
  • the double-walled insert 4 forms with its two concentric tube walls 41 and 42 an annular gap-shaped intermediate space 43, which, as will be described below, as a flow channel for in the rear chamber K2, ie in the cup 9, located material component to the mouthpiece assembly 3, 6 is used ,
  • the insert 4 is suitably connected to the front end wall 2 of the cartridge tube 1, which can be done in a conventional manner by a correspondingly shaped, not shown in the drawings latching connection, but also by ultrasonic welding, gluing or the like. It is also understood that the insert 4 is centered by suitable measures not shown in the schematic drawings but known to those skilled in the art.
  • the front end wall 5 of the insert 4 is formed so that the inner partial chamber K1b is completed by this end wall, on which the inner mouthpiece 6 is formed, so that this inner partial chamber K1b through the inner mouthpiece 6 can be emptied ,
  • the front end wall 5 of the insert 4 by correspondingly arranged ribs, grooves or the like openings 51, 52, which connect the outer part of the chamber K1 a with the annulus between the mouthpiece 3 and the inner mouthpiece 6, and also the gap 43 connect between the tube walls 41, 42 of the insert 4 with the annular space between the mouthpiece 3 and the inner mouthpiece 6.
  • the annular piston 12 which closes the cup 9 and thus the rear chamber K2 has an annular groove 13, which, as the other drawing figures show, is arranged and formed complementary to the rear end region of the insert 4 projecting beyond the pistons 7, 8. so that this rear end portion when inserting the cup 9 in the cartridge tube 1 is immersed in this annular groove 13, and the annular piston 12 also has a ring of opening out into the annular groove 13 openings or holes 14.
  • the second material component from the rear chamber K2 when the cup according to FIG. 2 is inserted into the cartridge tube 1, in the serving as a flow channel gap between the tube walls 41, 42 of the insert 4 exit.
  • the means for sealing the two chambers until use namely the front chamber K1 in the mouthpiece area and the rear chamber K2, for example by a sealing foil over the annular piston 12, are not shown in the schematic drawings for reasons of simplicity.
  • FIGS. 2 to 5 show the function of the multi-chamber cartridge during the ejection process.
  • FIG. 2 shows the expressive cartridge.
  • the front end wall of the annular piston 12 of the cup 9 inserted into the cartridge tube 1 abuts against the rear end walls of the pistons 7 and 8; the bottom of the annular groove 13 in the annular piston 12 abuts against the rear end face of the insert tube walls 41, 42; the front end surface of the pipe wall of the cup 9 abuts against the rear end surface of the annular piston 7, and the front end surface of the pin 11 abuts against the rear end surface of the inner piston 8.
  • the cup 9 is advanced within the cartridge tube 1.
  • the annular piston 12 is fixed by the insert 4 in its axial position, while the annular piston 7 and the inner piston 8 are advanced through the tube wall of the cup 9 and through the central pin 11.
  • the two chambers K1 (consisting of the sub-chambers K1a and K1b) and K2 are thus axially compressed to the same extent, so that material is pressed out of these.
  • the material from the front partial chamber K1a passes through the passage openings 51 into the annular space between the mouthpiece 3 and the inner mouthpiece 6; Material from the inside Partial chamber K1b enters the interior mouthpiece 6, and material from the rear chamber K2 passes through the gap 43 of the insert tube walls 41, 42 and the outlet openings 52 also in the annular space between the mouthpiece 3 and the inner mouthpiece 6. From the mouthpiece assembly then get the Material streams from the space between the outer mouthpiece 3 and the inner mouthpiece 6 and from the inner mouthpiece 6 in a conventional, placed on the mouthpiece assembly mixer, the material components from the two chambers K1 and K2 (or, if the cartridge is used as a three-chamber cartridge , from all three chambers) intimately mixed.
  • FIG. 5 shows the final state with completely empty cartridge. As you can see, the emptying is almost free of residue. A small amount remains, except in the mouthpiece, only in the space 43 between the insert tube walls 41, 42nd
  • the mixing ratios can be selected within wide limits by appropriate choice of the relative cross sections of the component chambers K1 and K2.
  • the cross section of the rear chamber K2 in the cup 9 can be changed by more or less large diameter of the central pin 11, or by the outer diameter of the cup 9 is reduced, while the cup outer wall receives radial ribs for support within the cartridge tube wall 1.
