Fluidic nozzle for trigger spray applications

A method for making a fluidic nozzle for use with a trigger spray applicator that issues a desired spray pattern of liquid droplets into a surrounding gaseous environment, said applicator having a spray head with a liquid delivering orifice and an exterior surface proximate said orifice that is configured to receive said nozzle, said method comprising the steps of:

• forming a housing having a front and a rear face and between which passes a housing passage having a front and a rear portion,
• forming a fluidic insert having a front and a rear face and between which passes an insert passage that includes a portion configured as a fluidic circuit,
• configuring said housing passage front portion as a cavity that extends from an opening in said housing front face, said cavity configured so as to allow said fluidic insert to be press fitted through said housing front face opening and into said cavity,
• wherein said fluidic circuit configured so as to aid in providing said desired spray pattern
• wherein said spray head having a centerline and said spray head orifice being off said centerline, and said spray head exterior surface configured to receive a nozzle having a circular shape so as to receive a rotatable nozzle,
• said housing passage having a wall separating said front and rear portions,
• said wall having a rear face and a front face and an orifice between said wall faces, said orifice situated in said wall so as to be alignable with said spray head off-centerline orifice,
• said housing passage rear portion configured so as to allow said housing to fit on said spray head configured to receive said rotatable nozzle,
• said fluidic insert having at least a second passage extending between said faces and in which a portion of said second passage is configured as a fluidic circuit,
• each of said passages containing said fluidic circuits having an opening in said insert rear face that allows fluid to enter each of said circuits,
• said fluidic circuit openings situated in said insert rear face so as to be alternately alignable with said wall orifice as said housing is rotated on said spray head so as to allow a nozzle user to choose which of said fluidic circuits is aligned for said flow of liquid from said applicator.
