Abstract
A sustained duration trigger sprayer capable of dispensing at least 3 mL of product over a time period of about 3 seconds utilizing a force-to-actuate of between about 10 pounds and about 15 pounds. The trigger sprayer includes an enlarged piston bore and piston and an elongated trigger lever creating a high output fluid displacement with a 0.5 inch displacement distance. The container bottle and/or the sprayer shroud are contoured to provide a gripping area opposing the terminal end of the trigger lever wherein the gripping distance in from the gripping area to the terminal end of the trigger lever is no greater than 3.3 inches.
