Trigger sprayers have a really straightforward design and work with several parts to make sure the pumping action delivers liquid in the bottle as a spray. The trigger lever, once pulled using a few fingers activates a small pump. This pump is attached to a plastic tube that draws cleaning fluid from the bottom of the reservoir inside the bottle. The pump forces this liquid down a narrow barrel and out a small hole at the spray valve.
Inside the shroud, there is a small spring that compresses the fluid once pulled back by the trigger. The moving piston compresses the spring, so when you release the trigger, the piston is pushed back out of the gasket. These two strokes of the piston move the cylinder out again and contribute to the entire pump cycle.
This extraction motion shrinks the cylinder and forces the fluid out as a one-way system. Once the trigger is released, the motion allows the processes to be repeated without any delivery problems. Slightly different designs are used depending on the pump type and delivery solution.
Trigger sprayers are used in a wide range of liquid product packaging. It is mostly used in the packaging of cleaning products. This includes sanitizing agents, soaps and cleaning foams.
Trigger sprayers can also be used for hair-care products such as gels and sprays or on strong cleaning agents such as stain removers or alloy wheel cleaners. The medical industry also uses trigger pump sprays for pain relief products. You will probably find a trigger sprayer being used for some type of solution in most industries.
