A trigger sprayer is a handheld device used for dispensing liquids in a controlled manner. It typically consists of a plastic or metal trigger attached to a nozzle. When the trigger is squeezed, it activates a pump mechanism that draws liquid from a container and sprays it out. The sprayer is often ergonomic in design, with a comfortable grip and a trigger that is easy to squeeze. The nozzle typically has an adjustable spray pattern, allowing the user to select between a fine mist, a jet stream, or a wide spray. Trigger sprayers are commonly used for household cleaning solutions, gardening applications, and in various industries for dispensing different types of liquids.
