ABSTRACT:
A packaging machine having a sterile tunnel is provided with an outlet gate at the downstream end into which a ram lifts the filled cups. Since the gate opening is always partly obstructed by a cup and as each cup is lifted into the opening by the limited stroke of the ram a cup previously obstructing the opening is removed, the losses of air through the opening are limited and pressure fluctuations in the tunnel are reduced.
