A nozzle for a viscous liquid dispensing apparatus has a nozzle tip with a generally conical outer surface that tapers toward a dispensing orifice and forms an annular discharge air passage substantially parallel to the conical outer surface. Pressurized fluid is directed over the conical outer surface toward the dispensing orifice and thus, prevents viscous liquid dispensed from the dispensing orifice from being pulled back toward the nozzle tip and accumulating on the conical outer surface of the nozzle tip.
