Technical Field

[0001] This utility model relates to the field of cosmetic container technology, specifically to a polymer thermoplastic spring and an all-plastic pump core. Background Technology

[0002] Currently, all industries are following the principle of environmental protection, biodegradability and sustainable development, and skin care products are also actively responding by investing in research and development. At present, most of the pump head and pump core reset springs of skin care and washing products on the market use stainless steel metal springs. Although stainless steel springs have good elasticity and strong fatigue resistance, they need to be disassembled with plastic parts and then sorted for recycling, which makes recycling very costly. As a result, due to cost considerations, it is difficult to recycle and reuse them. Utility Model Content

[0030] The plastic spring assembly 4 is the first assembly 14, which includes a first spring 8 and a second spring 9. The plastic spring assembly 4 can use either the first spring 8 or the second spring 9 in the first assembly 14. The first spring 8 is adjusted by removing and adjusting a local rib to obtain the second spring 9.

[0031] The plastic spring assembly 4 is the second assembly 15, which includes a third spring 10 and a fourth spring 11. The plastic spring assembly 4 can use either the third spring 10 or the fourth spring 11 in the second assembly 15. The third spring 10 is adjusted by partially cutting off the ribs to obtain the fourth spring 11. The third spring 10 and the first spring 8 are strong springs, and the second spring 9 and the fourth spring 11 are soft springs. Strong springs are suitable for products with thick material and strong rebound force, while soft springs are suitable for products with thin material. Antioxidant material is added to the first spring 8, the second spring 9, the third spring 10, the fourth spring 11, the fifth spring 12, and the sixth spring 13. The first spring 8, the second spring 9, the third spring 10, the fourth spring 11, the fifth spring 12, and the sixth spring 13 are made of food-grade plastic.

[0032] Plastic spring assembly 4 is the fifth spring 12.

[0033] Plastic spring assembly 4 is the sixth spring 13.

[0034] The plastic spring assembly 4 is the seventh spring 18, which is obtained by adding an S-shaped rib to the fifth spring 12.

[0035] The plastic spring assembly 4 is the third assembly 22. The third assembly 22 includes an eighth spring 19, a ninth spring 20 and a tenth spring 21. The plastic spring assembly 4 can use any one of the eighth spring 19, the ninth spring 20 and the tenth spring 21 in the third assembly 22. The eighth spring 19 controls the pressing force and the rebound force by adjusting the wire diameter to obtain the ninth spring 20 and the tenth spring 21.

[0036] In summary, when using this polymer thermoplastic spring and all-plastic pump core, the plastic spring assembly 4 is installed on the outside of the main column 5, the bottom end of the main column 5 is connected to the top end of the plastic pump core assembly 2, and the top end of the plastic spring assembly 4 is connected to the outside of the top end of the main column 5. When the operator presses the nozzle 6, the nozzle 6 drives the main column 5 to move downward, so that the material inside the bottle 1 enters the nozzle 6 through the plastic pump core assembly 2 and the main column 5, and is then extruded through the nozzle 6. When the operator stops pressing the nozzle 6, the plastic spring assembly 4 pushes the nozzle 6 to drive the main column 5 upward, so that the nozzle 6 returns to its original position, so that the material stored inside the bottle 1 can be pressed and used later.
