(57) A machine for packaging products into relative containers (1) in a protected environment
includes a plurality of work stations, respectively, a station (10) for preparing
the containers (1), a station (20) for their sterilization and cooling, a container
filling station (30) and a container closing station (40). The filling station (30)
and the closing station (40) are aligned one after the other, in a controlled atmosphere
chamber (50), which is defined by a bottom wall (51), an upper wall (52), a lateral,
outer wall (53), front (54) and back (55) walls, and by a lateral, inner, airtight
wall (56, 156), which is situated longitudinally and laterally with respect to the
filling station (30) and the closing station (40). The chamber (50) isolates the stations
(30, 40) from the respective operating means (60), which are mechanically connected
to the respective work station by airtight passages, made in the lateral, inner wall
(56). Flow generating means (70) are made in the upper wall (52) for creating and
filtering a laminar flow of air (71), directed to the bottom (51) and involving at
least the filling station (30) and the closing station (40).
