Abstract

The invention relates to a device comprising a mixer tube (2), whose diameter diminishes toward one end, a mixer helix (5), which is located inside the mixer tube (2), and comprising a plunger (6,7). According to the invention, the mixer helix can or should be accordingly compressed inside the mixer tube with the aid of the plunger that is inserted into the mixer tube. The device enables a largely complete dispensing of the material remaining in a static mixer helix during mixing and is suited, above all, for storing, mixing and dispensing dental materials.
