A nozzle insert (l) for the nozzle (l4) of a squeezable tube (l5) or other dispenser consists of a hollow cylindrical body having a first part (2) carrying raised axially extending circumferentially spaced plateau regions or ribs (3) separated by grooves (4), and a second part (9) having a smoothly cylindrical outer wall (l0) and being of greater length than the first part (2). The insert (l) enables two different paste materials (l7, l8) to be extruded from the tube (l5) in the form of a striped stream. |
