Abstract
The nozzle (12) includes a dispensing passage (40) in which is located a tapered needle (10) which forms a seal. Since the nozzle isresilient, it is stretched slightly by needle movement beyond a seal-forming point. As the needle is retracted, the nozzle returns to its original shape. The passage has a reduced-size outlet at its forward end. Pref. the nozzle is formed of an injection moulded plastics resistant to the material to be dispensed. The needle taper increases towards its tip (11).
