A packaging machine for forming a web of packaging material into a vertical tube, filling contents into the tube, dividing the tube into lengths each corresponding to one container and forming each length into a baglike container. The machine comprises a filling device for filling a liquid into the tube to a specified level with the lower end of the tube closed, and a cleaning device for cleaning a required portion of the filling device. The filling device has a vertical filling pipe to be covered with the tube. The cleaning device has a vertical tubular jacket having a top wall and covering the upper portion of the filling pipe, a bottomed tubular cleaner removably connectable to the jacket for covering the lower portion of the filling pipe, and a cleaning liquid collecting duct removably connectable to the jacket. A cleaning liquid is supplied to the filling pipe with the duct connected to the jacket to clean the pipe and is thereafter collected through the duct.
