Numerous spray bottle types are available on the market, catering to different applications and needs. Some common types include: 1. Trigger spray bottles: These are the most common type of spray bottles, featuring a trigger lever that activates a small pump when squeezed. They're often used for cleaning, hair care, and gardening products. 2. Aerosol spray cans: These contain a propellant and a compressed liquid, which is released as a spray when the nozzle is pressed. They're used for products like deodorants, hairsprays, and spray paints. 3. Pump spray bottles: Similar to trigger spray bottles, this simple spray bottle uses a pump action to dispense the liquid as a spray, but instead of a trigger, they have a button or cap for pumping. These bottles are often used for personal care products like facial mists and hair sprays. 4. Fine mist spray bottles: These bottles are designed to create a very fine and even mist because of the spray valve. They're commonly used for fragrances, essential oils, and other similar applications.
