Abstract
The invention describes an apparatus for the sterile packaging of flowable substances, comprising a conveyer belt (4), from one end of which open packages (5) can be passed by an intermediate conveyer means (21-23) through a sterilizing chamber (7) and to a second conveyer belt (13) disposed in a sterile chamber (15) enclosed in a housing (14), filling means (17) and sealing means (18) being disposed in this sterile chamber (15) while an outlet sluice (24) is disposed in a wall of the housing. In order to simplify and so further improve such an apparatus that a more effective sterilization process is achieved, it is according to the invention envisaged to construct the sterilizing chamber (15) as an inlet sluice (8).
