ABSTRACT:
A nozzle attachment for removing residual material retained on the dispensing nozzle of a fluid dispenser, having a retainer adapted to releasably attach the nozzle attachment to a dispensing nozzle, and a pair of hollow-bodied nozzle attachment components that define, when nested together, an intervening space useful as a gas passageway for pressurized gaseous fluid introduced and directed to a discharge opening at a lower axial end of the nested nozzle attachment components. The gas passageway is adapted to emit gas introduced into the gas passageway as a gas stream in a manner effective to remove residual material clinging to the nozzle. Dispensers using the nozzle attachment are presented, including one using a truncated valve head.
