The first bottom surface 231 of the sealing ring 230 is designed as a flat surface, while the side surface 232 is designed as a cylindrical or conical surface, facilitating the shaping of the sealing ring. This application achieves airtightness while reducing the overall size of the cosmetic container, thus meeting user demand for miniature cosmetic containers.

[0058] like Figure 5-7As shown, the bottom assembly 300 includes an outer bottom 310 and a loading tray 320. The loading tray 320 is used to store cosmetic materials. The middle ring 220 is fixedly mounted on the loading tray 320, and the middle ring 220 is installed in the outer bottom 310. The loading tray 320 is used to store cosmetic materials, including powder, paste, cream and other materials.

[0059] like Figure 6 and Figure 7 As shown, the outsole 310 and the loading tray 320 are split structures, and the middle ring 220 can be detachably installed in the outsole 310; in this embodiment, the outsole 310 and the loading tray 320 are independently injection molded, and then the loading tray 320 is fixedly installed in the middle ring 220, and the middle ring 220 can be detachably installed in the outsole 310.

[0060] When the material in the loading tray 320 is used up, the loading tray 320, inner cover 210, and middle ring 220 are removed and replaced with a new loading tray 320, inner cover 210, and middle ring 220 for continued use. Therefore, other components of the cosmetic container can be reused, which is energy-saving, environmentally friendly, and cost-effective. During assembly, the loading tray 320 is first installed on the middle ring 220, and then the material is filled into the loading tray 320. After filling, the middle ring 220 is installed in the base assembly 300.

[0062] Optionally, the outer diameter of the cover assembly 100 is D1, the outer diameter of the liner assembly 200 is D2, and the outer diameter of the bottom assembly 300 is D3, wherein 40mm≤D1≤60mm, D1>D2, and D1≥D3. Optionally, D1 is 55mm±2mm. The so-called outer diameter of the cover assembly 100 refers to the outer diameter of the outer cover 110, the so-called outer diameter of the liner assembly 200 refers to the outer diameter of the widest part of the liner assembly 200, and the so-called outer diameter of the bottom assembly 300 refers to the outer diameter of the widest part of the bottom assembly 300. In the present application, the upper surface of the outer cover 110 is a circular structure, and the outer diameter of the outer cover 110 is about 55mm. The outer diameters of other components in the cosmetic container are all less than or equal to the outer diameter of the outer cover 110, that is, the overall outer diameter of the container is controlled at about 55mm. Compared with traditional containers with an outer diameter of about 80mm, the cosmetic container of the present application is more compact, lightweight, and easy to carry.

[0063] like Figure 1 and Figure 2 As shown, the inner cover 210 has a second bottom surface 213, and the first bottom surface 231 is flush with the second bottom surface 213. The sealing ring 230 is located on the lower end surface of the inner cover 210. The inner cover 210 and the sealing ring 230 are integrally molded by two-color injection molding. The integral injection molding of the inner cover 210 and the sealing ring 230 provides a high bond strength and a good sealing effect. Optionally, the hardness of the sealing ring 230 is less than that of the inner cover 210 and the middle ring 220. The use of the elastic sealing ring 230 to seal the inner cover 210 and the middle ring 220 improves the airtightness of the inner cover 210 and the middle ring 220. The first bottom surface 231 and the side surface 232 of the sealing ring 230 are both designed to be flat, and the first bottom surface 231 and the second bottom surface 213 are aligned on the same level, facilitating the integral molding of the inner cover 210 and the sealing ring 230.

[0064] like Figure 2 As shown, the inner sidewall of the center ring 220 extends radially inwardly along a circle of annular ribs 224, which are embedded in the side surface 232 of the sealing ring 230. When the inner cover 210 is placed on the center ring 220, the annular ribs 224 on the center ring 220 and the sealing ring 230 form an interference fit, and the annular ribs 224 squeeze the sealing ring 230 to achieve an airtight fit between the sealing ring 230 and the center ring 220.

Figure 1 As shown, the first hinge shaft 314 passes through the first hinge 111 and the hinge hole 311 to rotatably connect the outer cover 110 to the outer bottom 310 .

[0066] The second hinge assembly includes a second hinge 211, a third hinge 226 and a second hinge shaft 227. Figure 9 As shown, a second hinge 211 is fixedly provided on the inner cover 210. Figure 10 and Figure 11 As shown, a third hinge 226 is fixedly provided on the middle ring 220. Figure 5 As shown, the second hinge shaft 227 is provided through the second hinge 211 and the third hinge 226 to rotatably connect the inner cover 210 to the middle ring 220. Figure 9 As shown, the inner cover 210 extends radially outward to form a flange 212, which facilitates the opening of the inner cover 210.

[0067] like Figure 1 As shown, the fastening assembly includes a first buckle 113 and a second buckle 313, as shown in FIG. Figure 8 As shown, the outer cover 110 is provided with a protrusion 112, and the protrusion 112 is provided with a first buckle 113, as shown in FIG. Figure 12 As shown, the outer bottom 310 is provided with a spring clip 312, which is provided with a second latch 313. The first latch 113 and the second latch 313 engage with each other to securely connect the outer cover 110 to the outer bottom 310. A portion of the spring clip 312 is disconnected from the outer bottom 310, allowing the spring clip 312 to be elastic. This elasticity facilitates the separation and engagement of the second latch 313 with the first latch 113, thus facilitating the opening and closing of the outer cover 110. Attaching the first latch 113 directly to the outer bottom 310 and the second latch 313 directly to the outer bottom 310 further simplifies the structure of the cosmetic container and reduces its space.

[0068] like Figure 10 and Figure 11 As shown, the inner side wall of the middle ring 220 extends radially inward to form a support ring 222. The middle ring 220 includes a first joint portion 221 and a second joint portion 223. The first joint portion 221 and the second joint portion 223 are respectively located on both sides of the support ring 222.

That is, the loading tray 320 is fixedly installed on the second joint portion 223. Figure 1 and Figure 2As shown, a mesh cloth 240 is welded on the support ring 222, the first joint portion 221 is located above the support ring 222, and the inner side wall of the first joint portion 221 forms an annular rib 224 radially inward. The inner cover 210 is airtightly combined with the first joint portion 221 of the middle ring 220 through the sealing ring 230 and the annular rib 224, the second joint portion 223 is located below the support ring 222, and a first hook 225 is provided on the inner side wall of the second joint portion 223, the loading tray 320 is installed in the second joint portion 223, and the first hook 225 is engaged with the second hook 321 to fix the loading tray 320 in the middle ring 220.

[0069] Example 2: Figure 13-18 As shown, the cover assembly 100 includes an outer cover 110, a top sheet 130, and a lens 120. The lens 120 is fixedly attached to the inner sidewall of the outer cover 110, and the top sheet 130 is fixedly attached to the top surface of the outer cover 110. This embodiment differs from Example 1 in that the top sheet 130 is attached to the top surface of the outer cover 110 in this embodiment. The top sheet 130 has a leather-like appearance and feel. Attached to the outer surface of the cosmetic container, it not only protects the container but also gives it a leathery feel, enhancing the product's quality. The top sheet 130 is made of plastic, which is more wear-resistant and resilient than leather. Compared to traditional stamped silicone substrates with imitation leather surfaces, the top sheet 130 has greater hardness, toughness, and durability. Optionally, the top sheet 130 is provided with a logo in the form of letters, numbers, Chinese characters, or other special symbols, integrally injection-molded with the top sheet 130. Optionally, the top sheet 130 includes a patch substrate made of TPU, PP, PVC, or PET, wherein TPU (ThermoPlastic polyUrethane) is thermoplastic polyurethane elastomer rubber, PET (PolyEthylene Terephthalate) is polyethylene terephthalate, PP (PolyPropylene) is polypropylene, and PVC (PolyVinyl Chloride) is polyvinyl chloride.

[0070] Example 3: Figure 19-24 As shown, this embodiment differs from Example 1 in that the outer bottom 310 and the loading tray 320 are integrally formed, with the center ring 220 fixedly mounted within the outer bottom 310. This means that the bottom assembly 300 is a one-piece component, further reducing the number of components in the cosmetic container and simplifying the product's production and assembly process. After the bottom assembly 300 is formed, the center ring 220 is simply fixedly mounted on the loading tray 320, making assembly easy.

[0071] Example 4: Figure 25-30As shown, the difference between this embodiment and embodiment 3 is that: in this embodiment, a top sheet 130 is attached to the top surface of the outer cover 110.

[0072] It should be noted that those skilled in the art may make a number of modifications and improvements without departing from the concept of this application, and these modifications and improvements are all within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be based on the appended claims.
