Abstract A sterile chamber for packaging various products comprises a sealed one-piece box divided internally by a partition into two separate compartments. One chamber has an upper opening for vertically introducing the packaging machine after which it is closed by a cover, and a lower opening for removing the packaged products on a conveyor belt through a bath of germicidal liquid. A lateral aperture is provided for supplying webs of plastic film to the packaging machine from two reels through a single cleaning device using germicidal lamps between the films. The second compartment houses a panel bearing remote-control elements for the packaging machine. A door in the partition gives access from the control compartment to the packaging compartment and a transparent window in the partition permits observation.
