Definitions

  • the present invention relates to an ejection gun for two-component cartridges consisting of a manually operated pistol grip, a trough-shaped half-shell, a piston rod slidably mounted therein and an essentially circular ejection plate arranged at the front end of the piston rod.
  • Squeeze guns for cartridges which generally contain pasty masses, are widely used to replace aerosol-operated pressure cans.
  • the cartridge is inserted into the half-tub of the squeeze gun in such a way that its displaceable piston is acted upon by the squeeze plate of the squeeze gun, which in turn squeezes the pasty mass through the advance of the piston rod when the pistol grip is actuated.
  • a squeeze gun is not suitable for simultaneously squeezing two pasty masses contained in a cartridge.
  • Such a cartridge is described in DE-A-38 14 633 by the applicant. It is a container for pasty masses, consisting of a cylindrical housing, which is divided by a longitudinal partition into two separate chambers, with an outlet opening being provided in the upper end of each chamber and a semicircular piston in each chamber is provided, which is displaceable in the direction of the outlet opening.
  • Several ribs are provided on the underside of the piston and a sealing lip is arranged along the outer edge of the piston crown.
  • a hand-operated sealing pistol which is used to squeeze out a cartridge, a trough-shaped half-shell being arranged on the front side of a hand-operated pistol grip.
  • a piston rod is fastened via a yoke, with at the front ends of the transport rod and Each piston rod is half a piston disc, so that simultaneous pressing of the two components from the cartridge follows when the transport rod and the piston rod are actuated simultaneously.
  • a disadvantage of this known sealing gun is that at the high pressures required to move the pasty masses in the chambers of the cartridge, the individual cartridge chambers are expanded laterally, since this lies loosely in the trough-shaped half-shell and is usually made of a flexible material.
  • the object of the present invention is to provide a squeeze gun for cartridges with which a precise simultaneous squeezing out of the pasty masses contained in the two chambers is ensured and with which irregular widening of the outer wall of the cartridge is avoided with certainty.
  • a cylindrical tube which is open on one side is arranged detachably and displaceably in the trough-shaped half-shell, in which two bent stamps are arranged at a distance from one another mirror-symmetrically to a plane containing the longitudinal axis of the tube are attached.
  • the punches are advantageously arranged in the form of a cylinder jacket section and are fastened to the tube sheet coaxially with the tube.
  • the tube consists of aluminum, the outer diameter of which is adapted to the inner diameter of the trough and the inner diameter of which is adapted to the outer diameter of the cartridge to be pressed out.
  • the one-sided open cylindrical tube with the two punches arranged therein has the advantage that it is from the ejection plate of a conventional ejection gun is pushed continuously over the double-walled cartridge, the stamp ends, which are offset somewhat to the rear, act on the semicircular piston heads of the two chambers;
  • the two semicircular pistons move in the direction of the ejection opening, with no expansion to the outside at the places of greatest stress on the wall of the double-wall cartridge, since this certainly prevents due to the cylindrical tube that encloses the double-wall cartridge becomes.
  • the advantage is achieved that it can also be used for other conventional squeeze guns, so that two-component cartridges can also be squeezed precisely with these known squeeze guns.
  • FIG. 1 shows a section through a two-component cartridge 1 in the form of a double-wall cartridge according to the aforementioned DE-A-38 14 683, which is provided with two outlet openings 2, 3 and a mixing tip which can be screwed thereon.
  • the cartridge 1 is divided by a partition 4 into two semicircular chambers, in each of which a pasty mass is arranged.
  • the bottom of the Cartridge 1 is closed by two semicircular pistons 5, which are displaceable in the direction of the outlet opening, wherein, as FIG. 3b in particular shows, the underside of each piston can be provided with a multiplicity of reinforcing rings 10.
  • a conventional squeeze gun (not shown), which consists of a manually operated pistol grip, a trough-shaped half-shell, a piston rod slidably mounted therein and an essentially circular squeeze gun arranged at the front end of the piston rod, is now one-sided open cylindrical tube 6 is inserted, in which two spaced stamps 8, 9 are attached.
  • the cylindrical tube 6 is closed at its end 7 assigned to the ejection plate of the ejection gun, the two punches 8, 9, the length of which is shorter than that of the cylindrical tube 6, being fastened to this base.
  • the two punches 8, 9 can, as shown in FIG. 2, have the shape of a cylinder jacket section, wherein they are arranged at a distance from one another in such a way that the partition 4 of the cartridge 1 can engage in the gap formed between them.
  • the cylindrical tube 6 can advantageously consist of aluminum, the outer diameter of which is adapted to the inner diameter of the trough-shaped half-shell of the push-out pisotle and the inner diameter of which is adapted to the outer diameter of the cartridge 1 to be pressed out.
  • cylindrical tube 6 can be used in all conventional squeeze guns with the appropriate dimensions, so that two-component cartridges can also be squeezed out with it.
