Definitions

  • the present invention relates to a dispensing cartridge with a storage cylinder and a delivery piston, the bottom surface of the cartridge facing the cartridge content is continuously deepened from the edge of the piston to a vent hole and the vent hole is closed by means of a closure.
  • a discharge cartridge is known from EP-A-344 491 by the same applicant.
  • this known discharge cartridge represented an advance over the known prior art, but tests have shown that this cartridge can also be improved.
  • FIG. 1 shows the discharge cartridge 1 with the storage cylinder 2, which is closed at the bottom by a lockable mouth 3.
  • the cylinder 2 in FIG. 1 already contains the precisely weighed amount of the filling compound 4.
  • a delivery piston 5 in the wall of which an O-ring 6 is inserted in order to seal it.
  • the delivery piston is usually made of a dimensionally stable material.
  • an elastic sealing lip molded onto the piston rim can also be provided, which rests against the inner wall of the cylinder. The contents of the cartridge are stored in the storage cylinder and later pressed out through the mouth when used.
  • the bore 9 is closed by a closure 10, which in the present example, see FIG. 2, can be locked in an annular groove 13 by means of a bead 11 on the head 12 of the closure.
  • the bead is attached to a resilient collar which ensures that the bead is pressed against the annular groove 13.
  • the vent hole 9 has, see Figure 3, seen from a certain height from the bottom surface, a cross-sectional constriction, for example in the form of a cross recess 14, the constriction serves as a restrictor against rapid outflow of the filling compound after the filling process has ended. This ensures complete ventilation.
  • a cross-sectional constriction for example in the form of a cross recess 14, the constriction serves as a restrictor against rapid outflow of the filling compound after the filling process has ended. This ensures complete ventilation.
  • the slots or inner grooves can also be designed differently and in different numbers.
  • the bottom surface of the piston has an arrangement of radially extending, slot-shaped depressions 15, which open out at the vent hole.
  • the piston can have radial ribs 16 above its bottom surface. The radially extending, slot-shaped depressions 15 and the ribs 16 are shown and drawn in detail in the aforementioned application.
  • a ventilation chamber 17 is arranged around the cylindrical ventilation bore 9, which is formed by a circumferential sealing cylinder 18 which is arranged at a distance from the wall 19 which forms the cylindrical ventilation bore 9 and in the inner surface of which the annular groove 13 is formed.
  • slots 20 are made, from which the filling compound can emerge, as shown in FIG. 2.
  • the filling compound can be filled, for example, from below through the open mouth 3, the exact volume of this compound being introduced by a metering device.
  • the mouth 3 is then closed.
  • the delivery piston is then inserted into the cylinder from above and pressed down against the filling compound until all air has escaped from under the piston head through the vent hole with throttle.
  • the complete ventilation can be visual are tracked and has occurred when the filling compound emerges from the slots 20 of the wall 19.
  • the closure 10 can then be pressed in until its bead 11 engages in the annular groove 13 and the shoulder 21 rests on the closure on the end face 22 of the wall 19.
  • the discharge cartridge is ready to enable the filling compound to be discharged precisely.
  • the filling compound can of course also be filled in with the mouth 3 closed on the delivery piston side, this depending on the filling system and the metering devices.
  • a closure screw can also be used, which can be constructed similarly to the aforementioned document, but must have a head which seals the overflow chamber.
