ABSTRACT:
An apparatus for aseptically filling a pack, held in position by a pack support which is designed for sealing the filled pack, has a filling head housing part encompassing and defining a filling head space for receiving and delivering fluid to be filled in the pack. A vertically displaceable valve, which has a valve opening and closure element which is positioned in the filling head space and which extends to and terminates in a cutting means for cutting a membrane of a pack to be filled, controls delivery and regulates the flow rate of the fluid to be filled in a pack from a fluid inlet and outlet pipe. An inlet valve and an outlet emptying valve connected to a bottom of lateral walls of the filling head space provide a sterilizing medium to the filling head space and remove it and any residual fluid from the filling head space.
