ABSTRACT:
A vacuum packaging machine (10) is provided having a base (12) and a pivotally mounted lid (14) which cooperatively define a package air evacuation chamber (76) adapted to receive the open end (98) of a filled flexible package (100), thereby allowing evacuation of air from the package (100) and heat sealing of end (98). The machine (10) is characterized by an essentially flat and uninterrupted, easily cleanable base upper wall (28) which eliminates concavities in the like which can lead to unsanitary collection of fluids or solids. The machine (10) also has a vacuum source (16) and a vacuum conduit assembly (18) the latter having conduits within base (12) and lid (14).
