Abstract

An application system is disclosed for two-component materials, and can include a moisture-reactive composition accommodated in a first packaging unit, a hardener component accommodated in a second packaging unit and a dynamic mixer configured for insertion into an applicator and to be driven by the applicator.

First claim

What is claimed is:

1. An application system for two-component materials, comprising:
a moisture-reactive composition accommodated in a first packaging unit;
a curing agent component accommodated in a second packaging unit;
a first cartridge accommodation device configured to hold the first packaging unit;
a second cartridge accommodation device configured to hold the second packaging unit; and
a dynamic mixer configured for insertion into an applicator and to be driven by the applicator, wherein:
the first packaging unit is a tubular pouch and the second packaging unit is a rigid-walled cartridge,
the first cartridge accommodation device is actuated by a linear piston connected to a linearly advanced toothed rack, and
the second cartridge accommodation device is actuated by a rotary piston connected to a rotating drive rod.

2. The application system according to claim 1 , wherein the dynamic mixer comprises:
at least one tapping element for opening the first and/or second packaging unit(s);
two premixing chambers; and
a rotor with rotor blades configured for producing an advance in connection with a mixing process.

3. The application system according to claim 1 , wherein the first and second packaging units are firmly connected to one another.

4. The application system according to claim 1 , wherein the applicator is battery-operated and comprises:
a holder for accommodating the first and second packaging units; and
an electrical drive with a battery current supply, which is configured for coordinated and metered expulsion of the moisture-curing composition from the first packaging unit and of the curing agent component from the second packaging unit as well as for driving the dynamic mixer inserted into the applicator.

5. The application system according to claim 4 , wherein the holder comprises:
the first cartridge accommodation device; and
the second cartridge accommodation device, and wherein the electrical drive comprises:
the linearly advanced toothed rack as a first expulsion rod with the linear piston connected thereto for expelling the moisture-reactive composition from the tubular pouch;
the rotating drive rod as a second expulsion rod with the rotary piston connected thereto and integrated for engagement in the rigid-walled cartridge for the curing agent component; and
a drive shaft for the dynamic mixer, wherein the linearly advanced toothed rack, the rotating drive rod, and the drive shaft for the dynamic mixer arranged on an outlet side of a transmission unit, the transmission unit being connected on an inlet side to an electric motor.

6. The application system according to claim 5 , comprising:
an elongate cylindrical housing in which are arranged, one after the other in a direction of a longitudinal axis, the holder for receiving the first and second packaging units, the first and second expulsion rods in an adjacent arrangement, the transmission unit, and the electric motor.

7. The application system according to claim 6 , comprising:
a handle which, in side view, is U- or V-shaped, and is arranged in a central section on a base body, and which is configured for accommodating a battery pack in an arm of the “U” or “V.”
