Abstract
The invention relates to a process for introducing a particulate material, for example pellets, granules or powder, into a liquid, and a cartridge and a device for carrying out this process. The material is introduced into a cartridge having a sleeve, an axis and a base arranged in the interior of the sleeve and displaceable along the axis away from a stop. Thereafter, the cartridge, in a position in which its axis is approximately perpendicular and the base rests against the stop under its own weight, is allowed to fall into the liquid, the cartridge being guided by a guide tube. On immersion in the liquid, the base is displaced upward away from the stop by the liquid, with the result that the material is ejected at least for the most part from the cartridge.
