Spray nozzle for anti-clog spray package
摘要:
The present invention provides a spray nozzle with both desirable aesthetic and functional attributes. The spray nozzle includes a central orifice and a plurality of blind recesses concentrically disposed around the central orifice, as well as an annular channel connecting all of the blind recesses. The recesses and the channel each individually provide desirable aesthetic properties, while in combination they each reduce the likelihood of product residue buildup in the other. The recesses interrupt the smooth walls of the channel to divert liquid product out of the channel before it can dry out.
