ABSTRACT:
A packaging apparatus for aseptic volumetric packaging has a fixed means for forming a flow of sterile air to the apparatus, a feed member, at least one pumping member which is movable relative to the flow of sterile air, at least one filler spout and at least one dispenser member attached to the pumping member and the filler spout and disposed so as to be alternatable between positions connecting the feed member to the pumping member and the pumping member to the filler spout. The pumping member comprising a cylinder connected to the dispenser member, a piston mounted to slide inside the cylinder, a drive rod fixed to the piston and connected to an actuator device, and an enclosure fed with sterile air and mounted adjacent the cylinder. The enclosure surrounds the drive rod of the piston and is fed with sterile air from the flow of sterile air by a fan member associated with the pumping member. The fan member moves together with the pumping member and has an intake orifice disposed in the flow of sterile air.
