  • the user moves the piston in the direction of the neck.
  • the filling material leaves the cartridge through the outlet channel of the neck and is applied at the location desired by the user.
  • filler material There are several alternatives available for filling the cartridge with filler material.
  • the piston is brought to a first alternative in a position which it occupies after completion of the conveying process, namely the position with a minimum distance to the outlet opening.
  • the neck of the cartridge is immersed in a reservoir with filling material.
  • the piston is moved away from the filling material from the outlet opening, so that filling material is introduced from the reservoir into the storage chamber.

  • the mixer housing 42 may each contain a corresponding sealing element, by means of which the corresponding outlet opening at the outlet end 28 of the cartridge can be closed.
  • the mixer housing 42 may include a coupling element 43 which is intended for engagement with the neck 2.
  • the coupling element 43 can be received in an engagement element 44 which surrounds the neck 2.
  • the engagement member 44 is designed as part of the neck 2.
  • the coupling member 43 can be displaced relative to the engagement member 44 so that the mixer housing is durable relative to the mixer and outlet end 28 either in a closed or open position.
  • the mixer housing 42 is held in an open position during filling to allow air present in the first or second subchambers 6, 7 to escape via exit ports leading to the exit end 28.
  • the mixer housing 42 is held in its open position as long as the filling is carried out in order to avoid that a pressure builds up in the first or second partial chamber 6, 7 which would make continued filling more difficult.
  • the mixer housing 42 is moved to its closed position, in which the outlet openings of the outlet channels 11, 12 are kept closed.
  • the first and second pistons 3, 4 are movable by means of a plunger 5 in order to discharge the two components 8, 9 at the same time.
  • the plunger is in particular designed such that it rests on the first and the second piston 3,4.
  • the plunger 27 is integrally connected in this embodiment with the piston 3.4.
  • the mixer housing 42 is moved from its closed position to the open position. In this position, the outlet openings at the outlet end are in communication with the mixing chamber, which extends in the interior of the mixer housing.
  • the first and second components 8, 9 and any air can be entered into the mixer. The air escapes in advance through the outlet opening of the mixer housing. Subsequently, the mixing of the first and second components 8, 9 takes place through the mixer 31.
  • air which between the first or second piston 3, 4 and the Fill mass is included, may be provided on the corresponding piston or on the inner wall of the corresponding sub-chamber vent holes or vent grooves, in Fig. 5 are not shown.
  • At least one of the storage chambers 5, 6, 7 can be at least partially transparent according to each of the exemplary embodiments, so that the filling level of the filling compound 8, 9, 15 in the corresponding storage chamber 5, 6, 7 can be controlled.
  • the operation of the cartridge 1 comprises the steps of filling the cartridge 1 with a filling compound 8,9,15 and the discharge of the filling material.
  • the outlet opening for the filling compound at the outlet end 28 of the cartridge may also be a ventilation opening 33.
  • the cap 13 may contain vents or in combination with the neck 2 a Form vent opening.
  • the size of the vent opening 33 can be adjustable, for example by providing a combination of a closure cap 13 with the neck 2, which has at least one conical surface.
  • the distance between the closure cap 13 and the neck 2 in the region of the conical surface can be configured such that in the closed state, the conical surface closes the opening in a fluid-tight manner, allows a small amount of air to escape in a partially opened state, and leaves the outlet in the fully open position allowed a large amount of air or allows the exit of the filling material.
  • a vent 33 may be provided on the piston 3.4.
  • the vent may in this case comprise a membrane which releases an opening under pressure for the escape of air, or a vent valve which opens under pressure or under rest of the plunger.
  • an opening or a groove can be provided on the inner wall of the housing or in the jacket area of the piston, which prevents the escape of air between the jacket area of the piston and the inner wall of the housing.
  • the discharge of the filling compound 8,9,15 comprises the following steps: opening the closure cap 13 of the filled storage chamber 5,6,7 discharge the filling material 8,9,15 by being pressurized in the storage chamber 5,6,7, for which the push-out element 3, 4, 30 is shifted in such a way that the filling volume in the storage chamber 5, 6, 7 decreases.
  • the vent opening which is in the open state, allow air, which is still trapped between the filling compound and the piston, can escape.
  • a first flowable component and a second flowable component 8, 9 can be introduced into a first partial chamber 6 and a second partial chamber 7, and during discharge the first and second fluid components 8, 9 can be introduced from the first and second partial chambers 6, 7 emerge, each of the first and second piston 3,4 of a movable plunger 27 is displaced by applying a compressive force in the corresponding first or second partial chamber 6, 7 such that the filling volume in each of the first and second partial chambers 6, 7 decreases.
