  • a multi-chamber dispensing device is provided with an adjusting ring, by means of which an axial positioning of the dispensing unit can take place, so that the dispensing unit can be displaced from the receiving unit in the axial direction and replaced by a new dispensing unit.
  • the adjusting ring can, for example, act on the dispensing unit in such a way that the dispensing unit is moved between a closed position in which a fluid flow between the chambers of the receiving unit, which is generally substantially in the form of a multi-chamber syringe body, and the dispensing channel of the dispensing unit is blocked, and an dispensing position can, in which a fluid flow between the chambers of the receiving unit and the output channel of the output unit is released.
  • the dispensing unit may be separated from the receiving unit immediately after completion of a use application of the multi-chamber dispenser and replaced with a new dispensing unit so that no substances are downstream of the exit openings of the chambers of the receiving unit more are available. With the removal of the dispensing unit also adhering thereto, already leaked from the chambers of the receiving unit shares of the otherwise stored in the chambers substances are eliminated.
  • the newly inserted dispensing unit can in turn lock by appropriate selection of the rotational position of the adjusting ring a fluid flow between the chambers of the receiving unit and the output channel of the output unit, up to the time at which the collar is rotated angularly and the output unit can be positioned so in that a fluid flow between the chambers of the receiving unit and the output channel of the dispensing unit is released.
  • the substances contained in the individual chambers can be mixed downstream of the outlet openings of the chambers and upstream of the discharge channel.
  • the chambers of the receiving unit may have different or equal volumes, so that by appropriate design of the respective outlet openings, a mixing ratio between the substances separately held in the chambers can be adjusted.
  • the adjusting ring has at least a first, a rest position representing rotational position in which by means of the output unit, a substance flow between the chambers and the output channel is blocked, and a second, an output position representing rotational position in which the substances from the chambers of the receiving unit by a piston pressure in the output channel can be conveyed and applied over this.

  • the adjusting ring preferably comprises at least one ramp, so that the dispensing unit undergoes an axial offset upon rotation of the adjusting ring.
  • the ramp is designed such that a rotation of the adjusting ring in a clockwise or counterclockwise direction makes it possible to reduce the output unit from the receiving unit.
  • the ramp can also be formed on the output unit, in which case the adjusting ring slides along the ramp as it rotates with an area formed therefor.
  • the end region of the ramp facing away from the chambers defines a third rotational position of the adjusting ring which represents an ejection or removal position, in which the dispensing unit can be removed from the neck region of the receiving unit in a simple manner.
  • the dispensing unit is moved by rotation of the adjusting ring by means of the ramp from the neck region of the receiving unit.
  • the output unit is inserted in this case so before appropriate actuation of the adjusting ring in the neck region of the receiving unit.

  • the adjusting ring is designed so that the actuating arm rests in the rest position representing the first rotational position on a shoulder of the adjusting ring. Rotation of the adjusting ring to the second output position representing rotational position then releases the dispensing unit so that it can be manually pressed in the direction of the chambers of the receiving unit, which in turn can release fluid flow between the chambers and the dispensing passage of the dispensing unit.
  • a further rotation of the adjusting ring taking place in the same direction of rotation then allows the actuating arm to slide with its front side along the ramp of the adjusting ring, which in turn causes an axial displacement of the dispensing unit in the direction away from the chambers, so that the dispensing unit either ejected or simply from the Recording unit can be removed.
  • At least one stop is provided on the outer wall of the neck area for the actuating arm arranges, which preferably cooperates with a transverse web of the actuator arm.
  • the stop can secure the dispensing unit in the rest position and / or in the dispensing position of the adjusting ring.
