A manually actuated liquid sprayer has an element mounted on its nozzle for movement parallel to the axis of the discharge orifice between retracted and extended positions relative to the front wall of the nozzle, the element having a thickness not greater than the lateral extent thereof, lying against the front wall in the retracted position and being spaced from such wall in the extended position. The element has an open port coaxial with the discharge orifice and of a size greater than that of the orifice, the element comprising a mitigating element for mitigating the divergent spray issuing from the orifice. The open port is sized relative to that of the spray plume such that the mitigating element has no effect on the liquid spray as it passes through the open port without influence from any portion thereof in the retracted position, and such that the mitigating element is engaged only as it is extended to a position spaced from the forward wall of the nozzle to produce the intended modulation of the spray which emerges from the forward side of the element.

A manually actuated liquid sprayer having a nozzle containing a discharge orifice located in an outer wall through which liquid is capable of being discharged in the form of a divergent liquid spray plume of a given size in a forward direction, a perforate plate having a plurality of through opening

A manually actuated liquid sprayer having a nozzle containing a discharge orifice located in an outer wall through which liquid is capable of being discharged in the form of a divergent liquid spray plume of a given size in a forward direction, a perforate plate having a plurality of through openings and having a single open port coaxial with said orifice and of a size greater than that of said orifice, said plate being mounted on said nozzle for movement parallel to the axis of said discharge orifice between retracted and extended positions relative to said outer wall, and said plate comprising means for mitigating the divergent spray, said open port being sized relative to that of said spray plume such that said mitigating means has no effect on the liquid spray as it passes through said open port without influence from any portion thereof in the retracted position of said plate, and such that said mitigating means is engaged only as said plate is extended to a position forward of said nozzle outer wall to produce the intended modulation of the spray which emerges from the forward side of said plate.
