The spray bottle is a hand-operated lightweight dispenser designed to provide controlled release of liquid products, which can be converted into a stream with a variable spray volume, jet stream, or mist according to the needs of the specific application. There are many different sizes and types of spray bottles, and there are many uses for them. They are mostly used for makeup, so they are also called cosmetic sprayers.
The most common types of spray bottles are trigger sprayers and finger sprayers. Trigger sprayers usually have adjustable nozzles on them, which can be used to change the fineness and volume of spray products. Finger sprayers use up and down pumping motion on the spray actuator to release the product and are usually used for finer spray applications.
The spray bottle is composed of two main components-the bottles themselves contains liquid, and the sprayer responds to the action of the user's fingers and generates spray through a simple pumping action.
Bottles are usually made of polymer materials, such as low-density polyethylene (LDPE), high-density polyethylene (HDPE), polypropylene (PP), polyethylene terephthalate (PET), or similar polyolefins and polyolefins. ester. Glass can also be used in spray bottles, but because it is more fragile than polymers, it is not common.
