Manual device for dispensing a pasty filler

1. A handheld tool for dispensing a pasty filling material, the viscosity of which can be reduced by supplying oscillation energy, comprising:

a tool housing;

a detachable container for pasty filling material having an outlet nozzle at a front end;

an oscillation generator having a tube-like oscillating body;

means for exerting pressure on the pasty filling material, the means comprising a piston chamber and a piston rod, the piston chamber being disposed outside of and adjacent to the tube-like oscillating body, and the piston rod being guided axially through the tube-like oscillating body;

a pressure piston disposed in a rear region of the container; wherein the piston rod acts on the pressure piston in the container to dispense the pasty filling material from the container; and

means for pre-stressing the piston rod into a starting position, the means for pre-stressing the piston rod being disposed in the piston chamber,

wherein the oscillating body is directly connected to the detachable container via a quick-action connection including one or more of a screw connection and a bayonet connection.

2. The handheld tool of claim 1 , wherein the means for pre-stressing the piston rod into the starting position comprises one or more spring elements.

3. The handheld tool of claim 1 , wherein the outlet nozzle has a conical chamber directed toward the front end of the container and through which the filling material is channeled.

4. The handheld tool of claim 1 , wherein the tube-like oscillating body is connected to the detachable container in a central region of the container.

5. The handheld tool of claim 1 , wherein the oscillation generator is a pneumatically drivable oscillation generator.

6. The handheld tool of claim 1 , further comprising a common pressure supply for the oscillation generator and the means for exerting pressure on the pasty filling material.

7. The handheld tool of claim 1 , further comprising a piston disposed in the piston chamber and connected to the piston rod, the piston configured to move the piston rod responsive to compressed air being supplied to the piston chamber.

8. The handheld tool of claim 7 , wherein the means for pre-stressing the piston is disposed between an end wall of the piston chamber and the piston.

9. A container for use with a handheld tool for dispensing a pasty filling material, the viscosity of which can be reduced by supplying oscillation energy, the container comprising:

a tube-like component designed to accommodate pasty filling material; and

an outlet nozzle coupled to the tube-like component for dispensing the filling material,

wherein the container has, in a central region of the container, means for detachably connecting the container directly to a tube-like oscillating body of the handheld tool, the means for detachably connecting the container to the tube-like oscillating body including at least one of a screw connection and a bayonet connection,

wherein the container has in a rear region a pressure piston for exerting pressure on the pasty filling material, the pressure piston being guided axially through the tube-like oscillating body,

wherein the outlet nozzle includes an outlet opening arranged at a front end and the means for detachably connecting the container directly to the tube-like oscillating body is arranged at a rear end of the outlet nozzle opposite the front end, and

wherein the outlet nozzle comprises a flange at the rear end, the means for detachably connecting the container directly to the tube-like oscillating body being arranged on an inner surface of the flange.

10. The container of claim 9 , wherein the means for connecting the container to the handheld tool comprises a quick-action connection.

11. The container of claim 9 wherein the outlet nozzle has a conical chamber which is directed toward the front end and through which the filling material is channeled.

12. The container of claim 9 , wherein the pressure piston is movably disposed within the tube-like component.
