<p>There is disclosed a filling device (10'), comprising: a tank (6); a first fluidic line (12) extending between tank (6) and a pouring opening (14); a shutter (15) displaceable between an open position and a closed position in which it prevents the passage of pourable product at a section (19) of first fluidic line (12); a first chamber (60'); a second fluidic line (22, 61') fluidically connected with opening (14) and with first chamber (60') to allow a first aeriform to flow out from article (2) when shutter (15) is in open position or to convey a second aeriform within article (2) when shutter (15) is in closed position; and a third fluidic line (41') fluidically connectable with a segment of first fluidic line (12) placed upstream of section (19); first chamber (60') is selectively connectable to tank (6) or to an exhaust (46'); fluidic line (22, 61') is connected to chamber (60'); a first valve (62') interposed along second fluidic line (22, 61') and displaceable in an open position in which it allows the flow of first aeriform present in article (2) towards first chamber (60'); a second valve (50') interposed along third fluidic line (41') and displaceable to a position in which it allows the flow of pourable product towards first chamber (60'), when shutter (15) is in closed position and first chamber (60') is fluidically connected to tank (6).
