[0002] The pump sleeve is usually a protective cover on the top of the spray or cosmetic bottle nozzle. Magnesium-aluminum alloy is a kind of alloy with a general density of 1.8g·cm 3 The low density of magnesium and aluminum alloy improves its specific performance. Magnesium-aluminum alloy has good strength, rigidity and dimensional stability, which can play a good protective role on the nozzle.

[0003] Since the pump sleeve is connected to the bottle body, the surface of the existing pump sleeve is smooth. When in use, the cosmetic liquid may stick to the surface of the pump sleeve, and it is easy to slip when tightened, which is inconvenient to operate; cosmetics are formed by blending multiple ingredients, which will produce certain sediments, which may cause the pump body to be blocked when passing through the pump body. Most of the existing pump bodies are directly fixed on the pump sleeve, which is not convenient for disassembly and repeated use. Utility Model Content
