ABSTRACT:
A dual-section nozzle-head for use in a vacuum-packaging machine. The first section of the nozzle-head is provided with an interiorly-located manifold, that fluidly connects a series of first orifices, the exit-ends of which are located at the tip of the nozzle-head, so that these orifices may be fluidly coupled to the interior of packages at a sealing station of a vacuum-packaging machine for evacuating the packages via a vacuum source to which the orifices are connected. Interspersed between these first orifices are second orifices, which also have their exit-mouths at the tip of the nozzle-head. The second orifices are spaced apart, one from the other, along the length of the nozzle-head, and are coupled to a second manifold that is positioned exteriorly of the housing of the nozzle-head. The second manifold is coupled to a supply of protective inert gas.
