Open the CIPO recordAbstract From the Canadian patent
An air assisted spray nozzle assembly having an air cap effective for generating wide flat spray patterns with improved liquid particle breakdown utilizing relatively low air flow rates and pressures. The air cap includes a pair of longitudinally extending air passageways on opposite sides of a central liquid flow stream discharge orifice. The air flow passages each have a discharge orifice defined by a respective transverse deflector flange and a closely spaced inwardly tapered deflector surface which cooperate to deflect and guide pressurized air streams inwardly toward the discharging liquid flow stream for atomizing the liquid and for directing it into a well defined spray pattern.

Why it's free to use
- Filed January 24, 2001 and granted June 7, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 24, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 24, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
