[0029] Please refer to Fig. 2. Fig. 2 is a cross-sectional view of a cosmetic liner provided according to the embodiment shown in Fig. 1B. In Fig. 2, the second inner diameter D2 is smaller than the first inner diameter D1, which is smaller than the third inner diameter D3, which is smaller than the fourth inner diameter D4.

[0030] Generally, the annular sealing member 130 is formed from a resilient material, which may be a soft material. Functionally, the annular sealing member 130 serves to improve the sealing ability of the interior of the cosmetic liner 100.

[0031] Regarding the material of the annular seal member 130, the elastic material may include at least one of nitrile rubber (NBR), urethane rubber, natural rubber, elastomer, and silicone resin. Alternatively, the elastic material may be formed from at least one of polypropylene, polyethylene, acrylonitrile-butadiene-styrene (ABS), and thermoplastic elastomer (TPE) having elasticity. Note that in the embodiment of the present application, the material of the annular seal member 130 is not limited, and the annular seal member 130 may be formed as a member having elastic properties from various materials.

[0032] In one possible form, the material from which the annular sealing member 130 is manufactured is a single thermoplastic elastomer (TPE).

[0033] As described above, the cosmetic liner provided by the present application includes a liner cover, an inner sleeve, and an annular seal member. Here, the annular seal member is pressed between the annular ribs of the liner cover and the inner sleeve when the liner is in a closed state. At the same time, an engagement point is provided on the outer wall of the liner cover, and an engagement groove is provided on the inner wall of the inner sleeve, and the engagement point engages with the engagement groove when the liner transitions from an open state to a closed state, generating sound and corresponding vibration. The inner diameters of the annular ribs of the liner cover and the inner sleeve are both smaller than the inner diameter of the ring surrounded by the outer wall of the liner cover, and the inner diameter of the ring surrounded by the outer wall of the liner cover is smaller than the inner diameter of the ring surrounded by the inner wall of the inner sleeve. Therefore, the cosmetic liner designed by the present application can provide a good sealing effect and at the same time provide sound and vibration feedback, allowing the user to sense that the cosmetic liner is securely closed.

[0034] Please refer to Fig. 3. Fig. 3 is an installation diagram of an annular seal member provided by an embodiment of the present application. In Fig. 3, the annular seal member 130 is fused to the liner cover 110 by a bi-injection process.

[0035] In one possible manufacturing process, the material used for the liner cover 110 enters the cavity through a first gate of the mold, and the material used for the annular seal member 130 enters the cavity through a second gate of the first mold, and the two materials form their respective shapes within the first cavity, thus creating the effect of producing a fusion of the liner cover 110 and the annular seal member 130.

[0036] Bi-injection may also be called double injection, double injection, or two-color injection molding, and the embodiments of the present application are not specifically limited thereto.

[0037] As described above, the cosmetic liner provided by the present application can fix the annular sealing member to the liner cover by a bi-injection process, so that this design is convenient for later welding parts such as mesh and / or aluminum foil to the inner sleeve, which is convenient for rapid industrial production and can improve production efficiency.

[0038] Please refer to Fig. 4. Fig. 4 is an installation diagram of another annular seal member provided by an embodiment of the present application. In Fig. 4, the annular seal member 130 is fused to the inner sleeve 120 by a bi-injection process.

[0039] In one possible manufacturing process, the material used for the inner sleeve 120 enters the second cavity through a third gate of the second mold, and the material used for the annular seal member 130 enters the cavity through a fourth gate of the second mold, with the two materials forming their respective shapes within the second cavity, thus creating the effect of producing a fusion of the inner sleeve 120 and the annular seal member 130.

[0040] As described above, the cosmetic liner provided by the present application can fix the annular sealing member to the inner sleeve by a bi-injection process, thereby preventing the annular sealing member from moving back and forth and rotating along with the liner cover during use, reducing the probability of the annular sealing member falling off, and increasing the service life of the cosmetic liner while maintaining its high sealing performance.

[0041] 2 and 3, an annular seal member 130 is provided on the main member, which may be the liner cover 110 or the inner sleeve 120. Generally, the annular seal member 130 is fixed to the main member by a bi-injection process.

[0042] Please refer to Fig. 5. Fig. 5 is a schematic diagram of an inner sleeve provided by an embodiment of the present application. The outer wall of the inner sleeve 120 is provided with at least one bump 124 for releasably connecting with an outer sleeve of a composite container to form a composite container.

[0043] In one possible embodiment, the number of bumps 124 is an odd number, such as 1, 3, 5, or 7. Alternatively, the bumps 124 may be uniformly distributed on the outer wall of the inner sleeve 120. For example, if the number of bumps 124 is three, the angle between any two of the three bumps 124 is 120°.

[0044] In another possible embodiment, the number of bumps 124 is an even number, such as 2, 4, 6, or 8. Alternatively, the bumps 124 may be evenly distributed on the outer wall of the inner sleeve 120. For example, if the number of bumps 124 is 2, the angle between two bumps 124 is 180°. For further example, if the number of bumps 124 is 4, the angle between two adjacent bumps 124 out of the four bumps 124 is 90°.

[0045] In view of the above, the cosmetic container provided in the embodiment of the present application is detachably connected to the outer sleeve to form a composite container, thereby improving the service life of the composite container, enabling the outer sleeve to be used repeatedly, saving resources for producing the composite container, and improving resource utilization efficiency.

[0046] Please refer to Fig. 6, which is a schematic diagram of the mesh position in the inner sleeve provided by the embodiment of the present application. In Fig. 6, the mesh 125 is welded to the inner wall extension 122 of the inner sleeve 120. Here, the mesh 125 is used to allow the cosmetic body placed on the cosmetic liner 100 to permeate.

[0047] As described above, in the cosmetic container provided by the embodiment of the present application, a mesh is welded to the cosmetic liner. The mesh can allow the cosmetic body placed on the cosmetic liner to permeate. Therefore, the cosmetic liner provided by the present application can accommodate cosmetic bodies of various materials, thereby improving the versatility of the cosmetic liner.

[0048] Please refer to Fig. 7, which is a structural schematic diagram of a composite container provided by an embodiment of the present application. In Fig. 7, a composite container 70 includes a cosmetic liner 100 and an outer sleeve 200.

[0049] Schematically, the structure of the cosmetic liner 100 can refer to the contents of FIG. 1. Specifically, the cosmetic liner 100 includes a liner cover 110, an inner sleeve 120, and an annular seal member 130. Here, the annular seal member 130 is made of an elastic material. The liner cover 110 and the inner sleeve 120 are movably connected via a first rotating shaft 140. The annular seal member 130 is pressed between a first annular rib 111 of the liner cover 110 and a side wall step 126 of the inner sleeve 120 when the cosmetic liner 100 is in a closed state. The first annular rib 111 is provided on the inner surface of the liner cover 110, and the ring surrounded by the side wall step 126 is coaxial with the inner sleeve 120. The inner diameter of the ring surrounded by the first annular rib 111 is a first inner diameter, and the inner diameter of the ring surrounded by the side wall step 126 is a second inner diameter. Schematically, an outer wall of the liner cover 110 is provided with an engagement point 112 for engaging with an engagement groove 123 when the cosmetic liner 100 transitions from an open state to a closed state. The engagement groove 123 is provided in an inner wall of the inner sleeve 120. The inner diameter of the ring surrounded by the outer wall of the liner cover 110 is a third inner diameter, and the inner diameter of the ring surrounded by the inner wall of the inner sleeve 120 is a fourth inner diameter.

[0050] In the embodiment shown in FIG. 7, the outer sleeve 200 is removably connected to the cosmetic liner 100 .

[0052] In view of the above, the present application provides a composite container including a cosmetic liner and an outer sleeve, wherein the cosmetic liner and the outer sleeve are removably connected, thereby increasing the service life of the composite container, allowing the outer sleeve to be used repeatedly, saving resources for producing the composite container, and improving resource utilization efficiency.

[0053] Alternatively, since the composite container includes a cosmetic liner, the composite container can provide a good sealing effect by the cosmetic liner, and at the same time provide sound and vibration feedback to let the user know that the cosmetic liner is securely closed, thereby overcoming the problem that the cosmetic liner made of a traditional elastic material has a sealing material where the elastic material closes and absorbs pressure when the cosmetic liner is already securely closed, and the user cannot know whether the cosmetic liner is securely closed or not, and enhancing the feedback effect when the cosmetic liner with high sealing properties is closed, thereby improving the efficiency of the user's use of the cosmetic body in the composite container.

[0054] Please refer to Fig. 8. Fig. 8 is a cross-sectional view of a composite container provided by an embodiment of the present application. In Fig. 8, the cover assembly 810 of the outer sleeve 800 is in a closed state, and the first cavity 8A surrounded by the cover assembly 810 and the cosmetic liner 100 is used to accommodate a puff.
