The bottle cap on the cosmetic bottle body is formed by connecting the cap body and the cap. The cap is movable on the boss on the top of the cap body. There is a blocking valve on the boss on the top of the cap body, and the blocking valve is inserted on the cap. In the hole, it not only meets the functional requirements, but also ensures the needs of visual appearance, simple structure, convenient use, low cost, beautiful appearance.

Aluminum alloy strip/sheet for cosmetic cap

1. Light and soft: the density of aluminum is about one-third of that of steel;

2. Good strength: the tensile strength of pure aluminum is one-fifth of that of low-carbon steel, but after heat treatment strengthening and alloying strengthening, its strength will be greatly increased;

3. Good corrosion resistance: One of the characteristics of aluminum alloy is that a dense oxide film will be formed on the surface when exposed to air, which can prevent corrosion, so the corrosion resistance is good. If the "aluminum oxide film treatment method" is applied to it, the corrosion can be completely prevented;

4. Good processing performance: aluminum alloy has good extrusion performance, and secondary machining and bending are also easier;

5. Easy to regenerate: The melting point of aluminum is low, the regeneration is simple, and there is no pollution during disposal, which is conducive to environmental protection and conforms to the sustainable development strategy.
