<p>A filling system (10) of a packaging machine for reducing the mixing of product and air during the filling of a container with flowable material. The fill pipe (40) of the system (10) may have an elliptical cross section (306) reducing the velocity of material entering the container while allowing for increased production time. The system (10) includes a fill pump (75) and nozzle (80) having a collar (225), plurality of lugs (120, 230) and flexible flaps (130, 270) conformed to engage with the sidewalls of a container to thereby inhibit the mixing of product and air. The fill pipe (40) has an elongate body, an inlet end (300) and an outlet end (302). The inlet end (300) is in flow communication with the fill pump (750) and may have a circular cross section. The outlet end (302) is in flow communication with the nozzle (80) and may have an elliptical cross section. The cross section of the elongate body gradually transforms from a circular cross section at the inlet end (300) to an elliptical cross section at the outlet end (302).</p> |
