ABSTRACT:
A nozzle insert for an actuator head of a fluid dispenser includes a circular body having a central portion containing a discharge orifice, and an annular, conical flange extending radially outwardly from such central portion and being radially flexible relative thereto. The insert is seated within a smooth, cylindrical head bore having a constant diameter, and engages a cylindrical probe on the head concentric to the bore. An end wall of the flexible, conical flange faces outwardly of the bore and presents a sharp outer peripheral edge of a diameter slightly greater than the bore diameter. And, the insert body is of a harder material than that of the actuator head, so that the conical flange defines a circular, self-locking pawl for positively locking the insert fully seated within the bore as the sharp peripheral edge penetrates into the bore wall.
