Abstract (en)
[origin: WO9829307A1] Lidded jars (14) are placed in vacuum chamber (13), which is evacuated by vacuum pump (17) to create a vacuum in chamber (13) and to withdraw air from chamber (13) and jars (14), after which a valve (25) opens to admit air at atmospheric pressure into the chamber (13), thereby sealing lids (15) onto jars (14).
