DISPENSING NOZZLE HAVING A TUBULAR EXIT ZONE COMPRISING VANES

A nozzle and a process suitable for dispensing liquid foamable products, particularly useful with carbon dioxide blowing agents, the nozzle comprising a tubular exit zone having an inlet and an outlet; the tubular exit zone having an inner wall surface defining a passageway for dispensing having a centerline axis; the tubular exit zone further having a plurality of vanes attached to the inner wall surface parallel to the centerline axis with the vanes extending radially into the passageway for dispensing; the vanes having a length dimension that is the distance the vane contacts the inner wall surface parallel to the centerline axis, a thickness dimension that is the effective thickness of the vane at the inner wall surface perpendicular to the centerline axis, and a width dimension being the distance from the inner wall surface that the vane extends into the passageway for dispensing; and wherein the vanes do not connect or touch at the centerline of the passageway for dispensing.
