Trigger sprayers are handheld devices used to dispense liquids in a fine mist or stream. They typically consist of a plastic bottle, a trigger mechanism, and a nozzle. When the trigger is pulled, it creates suction that draws liquid from the bottle and forces it out through the nozzle, making them ideal for cleaning solutions, gardening, and personal care products. These sprayers are commonly found in households and industries, providing an efficient way to apply products like cleaning agents, pesticides, and hair sprays. Their adjustable nozzles allow users to control the spray pattern, enhancing versatility for various applications.
