A spray bottle is a bottle that can squirt, spray or mist fluids. Spray bottles are commonly used for dispensing cool cleaners, cosmetics, and chemical specialties. Unlike the rubber bulb dispenser which primarily moved air with a small amount of fluid, modern spray bottles use a positive displacement pump that acts directly on the fluid. The pump draws liquid up a siphon tube from the bottom of the bottle and forces it through a nozzle. Depending on the sprayer, the nozzle may or may not be adjustable, so as to select between squirting a stream, aerosolizing a mist, or dispensing a spray. In a spray bottle, the dispensing is powered by the user's efforts, as opposed to the spray can, in which the user simply actuates a valve and product is dispensed under pressure.
