Definitions

  • the present invention relates to the field of discharge cartridges for flowable materials.
  • Discharge cartridges in particular for two or more components, are increasingly being used in areas where only small quantities are required or where work has to be carried out in very tight spaces. Examples include the repair of electrical and electronic devices and the DIY sector.
  • the cartridges are usually made of plastic and are preferably manufactured using an injection molding process.
  • One type of the known discharge devices is characterized in that the cartridges are not on the collar, i. H. not be held near the discharge opening.
  • the pressure applied by the discharge piston can be absorbed directly by the holder on the discharge device.
  • the discharge device detects the cartridges on a flange on the bottom, i. H. at the end of the cartridge opposite the discharge opening of the cartridge.
  • the cartridge Since in these discharge devices the cartridge is only held on the floor, and consequently the cartridge body has to transmit the pressure exerted by the discharge piston from the tip to the holding flange and the latter has to transmit the force to the discharge device, the cartridge itself and in particular the holding flange must be correspondingly stable.
  • the cartridge body In the case of multicomponent masses which are only mixed when they are discharged in an attached mixing tube, or highly viscous masses, they can be considerable Forces occur even with relatively small cartridges with capacities in the milliliter range. This problem is exacerbated by the fact that, not least for environmental reasons, smaller cartridges with mixers with the smallest possible mixing volume and thus with a lower residual volume are sought.
  • these cartridges require higher pressures to discharge, in particular because of the smaller cross-section of the mixing tube.
  • the bodies of the cartridges could be adapted to these increased requirements by reinforcing the walls.
  • the holding flange on the other hand, tended to bend, break out or slip out of the adapter on the holding device.
  • the holding flange is carried out in at least two surfaces surrounding the cartridge body, which are connected to one another by webs, which results in a box construction. This is stable enough to withstand the forces when dispensing highly viscous masses from larger discharge cartridges.
  • the flange is only incomplete, e.g. B. needs to be held on two or three sides by the adapter on the discharge device.
  • the holding flange of the cartridge 1 consists of the two surfaces 2 and 3 penetrated by the cartridge body.
  • B. have a rectangular outline. The surfaces are connected by the webs 4 and thus form a box structure of high stability. It is sufficient, for. B. that the flange is gripped only on the long sides by the adapter on the discharge device. In most cases, however, there is a holding means on a third side, which also grips the holding flange and serves as a stop when inserting the cartridge into the adapter on the dispensing device.
  • Fig. 3 shows a reinforced version, in which there are further webs 5 which run at right angles to the webs 4.
  • This design of the holding flange requires only a little more material than a simple flange and can be implemented without problems in the common technology of producing discharge cartridges.
  • the flange according to the invention transmits the forces that occur during discharge from the cartridge body to the holder without deformation impairing the function.
  • the described design also does not cause the problems of shrinkage when injection molding large material thicknesses.
  • the flange can also be provided in the same way at the discharge end of a cartridge.
