Patent ID: 8827701

Claim:
A hand apparatus for dispensing a pasty filler mass the viscosity of which can be reduced by supplying vibration energy, comprising: an apparatus housing having an apparatus housing distal end and an apparatus housing proximal end; an oscillation part having an oscillation part distal end and an oscillation part proximal end, said oscillation part extending along an oscillation part axis only between said oscillation part distal end and said oscillation part proximal end, said oscillation part partially within said apparatus housing such that a region of said oscillation part is within a region of said apparatus housing that is adjacent said apparatus housing distal end, said oscillation part distal end extending distally beyond said apparatus housing distal end so that said oscillation part distal end is outside said apparatus housing; a container for the pasty filler mass, a vibration generator, an oscillation sleeve contained within said apparatus housing and disposed around an opposing oscillation part portion of said oscillation part; wherein said opposing oscillation part portion has surfaces that define a plurality of holes extending from inside said oscillation part to outside said oscillation part; and further comprising limitation rings fixed to said oscillation sleeve, said limitation rings disposed between said oscillation sleeve and said oscillation part; wherein the vibration generator and the container are mounted movably with respect to the apparatus housing and are directly vibration-coupled with each other.
