ABSTRACT:
A dropper, press fitted into the neck of a cyanoacrylate adhesive dispensing container, includes an elongated nozzle having a constant diameter passageway. The inlet to the nozzle is defined by a downwardly depending hollow boss having a sharp edged perimeter and sharp edged orifice. The sharp edged orifice and sharp edged perimeter tend to discourage retention of any droplets of cyanoacrylate adhesive to maintain the inlet free of residual cyanoacrylate adhesive and free of the crusting and clogging of the inlet which might otherwise occur.
