[0039] Example: Figure 1-16As shown, a highly airtight cosmetic container includes an inner cover 20, a middle ring 30, a sealing member 40 and a base 50. The middle ring 30 is fixedly installed in the base 50, the sealing member 40 is fixedly arranged on the middle ring 30, the base 50 is used to store cosmetic materials, the sealing member 40 includes a first sealing portion 41 and a second sealing portion 42, the inner cover 20 and the first sealing portion 41 are interference fit so that the inner cover 20 is airtightly covered on the middle ring 30, and the middle ring 30 and the base 50 are airtightly fitted through the second sealing portion 42.

[0040] In this application, if Figure 3 As shown, the middle ring 30 is installed in the base 50, the base 50 stores cosmetic materials, the inner cover 20 covers the middle ring 30, the seal 40 is fixed on the middle ring 30, the first sealing portion 41 of the seal 40 is interference-fitted with the inner cover 20, and the second sealing portion 42 of the seal 40 is interference-fitted with the base 50. Optionally, the mesh 38 is welded on the middle ring 30, and the base 50 and the inner cover 20 are respectively located on both sides of the mesh 38. Optionally, the inner cover 20 stores cosmetic tools, such as a powder puff, a cosmetic brush or a cosmetic cotton head, and the user uses the cosmetic tools to dip the cosmetic materials to complete the makeup process. The inner cover 20 uses the first sealing portion 41 to airtightly cover the middle ring 30 to seal the base 50, thereby effectively preventing external air from entering the base 50 from the inner cover 20, avoiding contamination and deterioration of cosmetic materials, and extending the service life of the cosmetic materials; the middle ring 30 uses the second sealing portion 42 to airtightly combine with the base 50 to prevent air from entering the base 50 from the gap between the middle ring 30 and the base 50, further improving the sealing performance of the cosmetic container, and also preventing the cosmetic materials in the base 50 from leaking.

[0041] In the present application, the first sealing portion 41 on the sealing member 40 is used to seal the inner cover 20 and the middle ring 30, and the second sealing portion 42 on the sealing member 40 is used to seal the middle ring 30 and the base 50, thereby simplifying the structure of the sealing member 40 and improving the sealing effect of the cosmetic container; since the sealing member 40 is fixed on the middle ring 30, the sealing member 40 does not need to move with the inner cover 20 during the opening and closing process of the inner cover 20. Compared with the structure in which the sealing member 40 is fixed to the inner cover 20, the sealing member 40 will not be separated from the inner cover 20 in the present application, thereby extending the service life of the product and reducing the waste of resources.

[0042] like Figure 4 , Fig.11 and Fig.14 The inner side wall of the first sealing portion 41 extends radially inward to form an annular rib 43, and the outer side wall of the inner cover 20 is recessed inward to form an annular groove 23, and the annular rib 43 is interference fit in the annular groove 23. The airtight effect between the first sealing portion 41 and the inner cover 20 can be further improved by using the annular rib 43 and the annular groove 23 that cooperate with each other.

[0043] Optionally, the middle ring 30 and the sealing member 40 are integrally formed by two-color injection molding. The middle ring 30 and the sealing member 40 are integrally formed by two-color injection molding, and the combination strength of the two is high and the sealing effect is good.

[0044] like Fig.12 and Fig.13 As shown, a gate 31 is provided on the middle ring 30, and the seal 40 is formed on the middle ring 30 through the gate 31, and the first seal part 41 and the second seal part 42 are respectively formed on both sides of the gate 31. During production, after the middle ring 30 is initially formed, the molten seal material is poured on the middle ring 30 through the gate 31, and the molten material flows from the upper layer of the middle ring 30 through the gate 31 to the lower layer of the middle ring 30, thereby forming the first seal part 41 and the second seal part 42, and the first seal part 41 and the second seal part 42 are fixedly connected at the gate 31, as shown in FIG. Fig.14 As shown, the molded seal 40 is provided with a groove 44. In the present application, a gate 31 is provided on the middle ring 30 to facilitate the processing and molding of the seal 40. When the cover is closed, the lower bottom surface of the inner cover 20 squeezes the first sealing part 41, so that the first sealing part 41 is deformed to achieve an airtight effect, and the second sealing part 42 is interference-fitted with the base 50 to achieve an airtight combination with the base 50.

[0045] like Fig.12 and Fig.13 As shown, the middle ring 30 includes a first joint portion 32, a support ring 33 and a second joint portion 34. The support ring 33 is circumferentially arranged on the inner wall of the middle ring 30. The first joint portion 32 and the second joint portion 34 are respectively located on the upper and lower sides of the support ring 33. Figure 4 As shown, the first sealing portion 41 is formed on the inner side wall of the first joint portion 32, and the second sealing portion 42 is formed on the inner side wall of the second joint portion 34. The gate 31 is opened on the support ring 33, and the sealing member 40 and the support ring 33 corresponding area form a groove 44, and the sealing member 40 and the gate 31 corresponding area form a connecting portion to fix the first sealing portion 41 and the second sealing portion 42.

[0046] Optionally, the inner cover 20, the middle ring 30 and the base 50 are made of hard plastic, and the seal 40 is made of elastic material, and the hardness of the hard plastic is greater than the hardness of the elastic material. Elastic materials include thermoplastic elastomers and various special saturated rubbers that cannot be vulcanized with sulfur, wherein the thermoplastic elastomers include thermoplastic polyurethane elastomer rubber TPU, thermoplastic polyester elastomer TPEE, styrene-butadiene-styrene block copolymer SBS, etc. The seal 40 is made of elastic material, so when the inner cover 20 is covered with the middle ring 30, it is convenient for the first sealing part 41 to deform so that the two are interference-fitted to achieve an airtight effect; when the middle ring 30 is installed on the base 50, it is convenient for the second sealing part 42 to interfere with the base 50 to achieve an airtight effect between the two, and the cosmetic material will not leak out. The middle ring 30 and the seal 40 are made of plastics with different hardness, and the hardness of the seal 40 is less than the hardness of the middle ring 30, so as to improve the sealing effect of the seal 40.

[0047] Among them, the hard plastic includes PET material, and the elastic material includes TPE material. PET (PolyEthyleneTerephthalate) is polyethylene terephthalate, which is a plastic with excellent strength and rigidity, good transparency and high temperature resistance, and is suitable for making high-strength, transparent and high-temperature resistant containers. TPE material is a thermoplastic elastomer material, and TPE has good elasticity. In this application, the inner cover 20, the middle ring 30 and the base 50 are made of PET material, so that the product has high strength, high hardness, and high transparency, and improves the quality and grade of the product. In order to solve the problem of poor sealing performance between the high-hardness inner cover 20 and the middle ring 30, and between the middle ring 30 and the base 50, a seal 40 is provided between the inner cover 20 and the middle ring 30, and between the base 50 and the middle ring 30, and the seal 40 is made of TPE material with good elasticity, thereby obtaining a cosmetic container with high strength, high hardness, high transparency and high sealing performance.

[0048] In a possible implementation, Fig.16 As shown, the base 50 includes a loading tray 51 and an outer bottom 52. The outer bottom 52 is located outside the loading tray 51. The middle ring 30 is fixed between the loading tray 51 and the outer bottom 52. The loading tray 51 is used to store cosmetic materials, including powder, paste, cream and other materials. The loading tray 51 and the outer bottom 52 are integrally formed; that is, the base 50 is an integrally formed part, thereby further reducing the parts of the cosmetic container and simplifying the production and assembly process of the product. After the base 50 is formed, the middle ring 30 is fixedly sleeved on the loading tray 51.

[0049] In another possible embodiment, the material loading tray 51 and the outer sole 52 are separate structures. In this embodiment, after the outer sole 52 and the material loading tray 51 are independently formed, the material loading tray 51 is fixedly installed in the middle circle 30, and the middle circle 30 is detachably installed in the outer sole 52.

[0050] When the material in the loading tray 51 is used up, the loading tray 51, the inner cover 20 and the middle ring 30 are disassembled and replaced with a new loading tray 51, the inner cover 20 and the middle ring 30 for continued use, so that other components in the cosmetic container can be reused, which is energy-saving, environmentally friendly and cost-saving. When assembling, the loading tray 51 is first installed on the middle ring 30, and then the material is filled into the loading tray 51. After filling, the middle ring 30 is installed in the outer bottom 52. During the process of filling the material, if a defect occurs due to misoperation, it is only necessary to remove the loading tray 51 separately and replace it with a new loading tray 51.
