A trigger pump sprayer in combination with a liquid dispensed from the sprayer. The trigger sprayer provides for efficacious particle size distributions of the liquids, when sprayed under non-ideal conditions. Non-ideal conditions include only partial strokes of the trigger, rather than full strokes and relatively slow trigger strokes. A bimodal distribution of particle sizes is obtained under two different operating conditions. The sprayer/liquid combination according to the present invention compresses the difference between the two modes, without requiring undue work by the operator. The advantageous particle size distribution difference is accomplished by using a precompression piston which reciprocates in response to trigger strokes, and selecting a liquid having appropriate properties to correspond to the trigger pump operating characteristics.

Trigger pump sprayer

A trigger pump sprayer in combination with a liquid dispensed from the sprayer. The sprayer is suitable for dispensing liquid from a reservoir, through a nozzle into particles. The trigger sprayer provides for efficacious particle size distributions of the liquids, when sprayed under non-ideal conditions. Non-ideal conditions include only partial strokes of the trigger, rather than full strokes and relatively slow trigger strokes. The trigger sprayer advantageously delivers a particle size distribution suitable for liquids having particular rheological properties. The advantageous particle size distribution difference is accomplished by using a precompression piston which reciprocates in response to trigger strokes, and selecting a liquid having appropriate properties to correspond to the trigger pump operating characteristics.
