ABSTRACT:
The disclosure relates to a dispensing unit for a filling machine for filling containers with particulate material comprising a nozzle having an outlet end for delivery of particulate material to a container. The nozzle is encircled by a downwardly facing seal to engage the upper open end of the container. The nozzle has an outer annular cavity terminating in an annular port around the open end of the nozzle in which a relatively high vacuum is drawn to evacuate the container and draw material through the passageway into the container. The nozzle has an inner annular cavity terminating in a porous wall encircling the discharge end of the nozzle in which a relatively low vacuum is drawn to adhere material in the nozzle to the wall of vacuum and terminate flow through the nozzle.
