ABSTRACT:
A dispenser for flowable media, particularly pasty pharmaceutical or cosmetic products, has a drag piston guided in a reservoir and is filled through a connecting piece through the drag piston. A riser is connected to a discharge pump and a reservoir closure. Thus, the interior of the reservoir to be filled can be well sealed from the outside during filling and ensures a clean, hygienic filling and simple installation of the dispenser. The drag piston is advanced to close the ventilation openings with a slide type control and the riser and discharge pump are filled with the medium following the filling process.
