摘要: A cap, spinner, and discharge nozzle assembly for use with a liquid dispensing apparatus such as trigger sprayer. The spinner can be externally fitted to the nozzle, includes an annular chamber surrounding central post having swirl in its top. longitudinal grooves, communicating tangential grooves wall defining chamber. Apertures are provided base of that pressurized flows through apertures into chamber, resulting reduction velocity, then along cap is which variably engages has at least projection on inner side front face, preferably groove formed by outer projection. may reversibly seal against floor and/or over wall.
