ABSTRACT:
A manually actuated liquid sprayer has a ported element selectively movable between a retracted position and an extended position at which the element lies in the path of the spray plume for mitigating the spray. The element has a cylinder with a smooth inner wall defining a turbulence chamber coaxial with the discharge orifice of the nozzle cap to which the element is mounted. A transversely extending perforate wall is located in the cylinder, and has an open port of a size greater than that of the discharge orifice and being coaxial therewith. The element is movable relative to the nozzle cap between the retracted position at which the liquid spray passes through the open port without influence from any portion thereof, and the extended position at which the liquid spray impacts against the smooth inner wall to mix with air in the chamber and passes through the perforate wall to create foam ejected from the element.
