An aerosol spray can is composed of a empty aerosol tin can, contents, aerosol valve and tupe, nozzle, and plastic cap.

An aerosol spray can is a product that is used once by sealing the contents together with the ejectant in a container equipped with a valve and spraying it in a predetermined form under the pressure of the ejectant. These products are applied by spraying, and the ejected material may be gaseous, liquid or solid, and the shape of the ejected material may be mist, foam, powder or micelle.

The aerosol spray can is a single-use product with an innovative design principle. It seals the contents together with the spray agent in a special container equipped with a valve. The spray agent creates a stable pressure environment inside the container, like a “power source” that is always ready to go. When the user presses the valve, the contents are ejected in a predetermined form, driven by the strong pressure of the agent. The use of these products is entirely dependent on the spraying operation, and the ejected substance can be in a wide variety of states, including gaseous, liquid, or solid. Moreover, the shape of the ejected substance varies, showing mist, foam, powder or micelle, etc., which greatly meets the diversified needs of different users and application scenarios.

The main aerosols on the market are divided into two main categories: daily necessities and industrial products.
