ABSTRACT:
A packaging machine having a filling device, a top breaker, a top heater and a top sealer which are arranged along a path of transport of containers. A hot air applicator is disposed between the filling device and the top breaker for eliminating the froth to be produced when containers, each having an upward opening, are filled with contents. The applicator includes a hot air discharge box having a bottom wall, a top wall, a side wall and two air outlets formed in the bottom wall, the air outlets being arranged along the transport path so as to be opposed to the openings of containers from above, and means for supplying hot air to the box. Each of the outlets is covered with a perforated plate, and has an edge portion provided with a downwardly extending annular portion for preventing the hot air from spreading out.
