Abstract
A one-piece, resilient nozzle on an outlet pipe of a carton filler includes two relatively rigid flaps at opposite sides of the nozzle and two relatively flexible walls at other opposite sides of the nozzle, to form with the flaps a loop encircling the nozzle interior. The flaps are biassed, by the inherent resilience of the nozzle, about an axis perpendicular to the nozzle and parallel to linear bottom edges of the flaps into a closed position wherein those edges come together along a linear zone at the base of a downwardly converging interior space bounded by the loop.
