ABSTRACT:
A packaging machine wherein product-loaded cup-shaped receptacles are advanced with an indexing movement through a series of packaging stations. One station includes a fixed vacuum/gas chamber extending entirely over one set of receptacles. The receptacles are first evacuated through this fixed chamber, and thereafter gas is directed into the chamber to fill the receptacles. A fine wire-mesh screen is positioned between the chamber and the receptacles to constrain the air and gas flow to a vertical direction, to prevent disarrangement of the product during evacuation and gassing. A gas-curtain structure develops an enclosed region of gas above the receptacles during their movement out from under the fixed chamber over to the final sealing station. The sealing operation takes place in two successive steps within the sealing station.
