摘要： A dosing apparatus in a form-fill-seal packaging machine comprises a delivery nozzle (12), a valve closure member (34) co-axial with the nozzle (12) and reciprocable co-axially relative thereto and bounding with the nozzle (12) an annular volume (35) therebetween for flow of liquid therethrough, fins (54) in the volume (35) and extending helically co-axially with the nozzle (12) for imparting a spiral motion to the liquid flowing through said volume, an annular valve closure seat (42) in and co-axial with the nozzle (12), respective annular portions of the seat (42) and the member (34) coming into sealing contact with each other, the annular portion of the member (34) comprising glass-fibre-reinforced plastics, a tubular bellows (44) extending between the nozzle (12) and the member (34) and sealingly separating in a liquid-tight manner the volume (35) from an interior chamber (46), and ducting (49, 50) which serves to supply a microbiocidal medium to the chamber (46).
