Abstract: A paint spray nozzle assembly for use with airless spray painting nozzles to protect against injection of sprayed paint through the skin of a user. The assembly includes a conically depressed nozzle cap with the nozzle opening at the bottom of the cone depression, the cone having a critical minimum depth. An additional assembly portion includes a projecting barrier extending outwardly beyond the nozzle preventing unintentional contact between the skin of the user and the fluid stream from the nozzle for a sufficient distance beyond the nozzle opening to prevent skin injection.
