ABSTRACT:
The invention relates to a dosing arrangement for filling of liquid nutrient materials, in particular salad-like products having solid, respectively chunky constituents, whereby a cylinder-piston-unit is mounted for a return sucking operation substantially in the immediate vicinity of the outlet end of a mouthpiece, respectively a mouthpiece chamber. Thereby an undesirable postdripping is prevented also during the filling of liquid containing products having solid constituents. In particular this effect is achieved by providing the mouthpiece with a return sucking cylinder connected thereto at its lower end by way of a conical communication channel and a transfer piece for receiving at least a slitted sealing membrane or the like sealing element.
