[0051] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the embodiments of the present application. Obviously, the embodiments described in the present application are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0052] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the following drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the objects used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0053] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0054] Example 1: Figure 1-19 As shown, a cosmetic container includes a thin and light cosmetic liner, the liner includes an inner cover 10, a middle ring 30 and a powder tray 40, the powder tray 40 is detachably installed in the middle ring 30, a sealing ring 20 is fixedly provided on the inner cover 10, the sealing ring 20 and the middle ring 30 are interference fit so that the sealing ring 20 can seal the middle ring 30, a first mounting portion 37 is provided at the upper part of the opening of the powder tray 40, a second mounting portion 41 is provided below the first mounting portion 37, and a gap is provided between the first mounting portion 37 and the second mounting portion 41, as shown in FIG. Figure 6 As shown, the thickness L1 of the inner container is 13 mm to 19 mm, the thickness of the inner cover 10 is L2, the thickness of the powder tray 40 is L3, and the ratio of L2 to L3 is 0.7 to 1.1.

[0055] Optionally, the powder tray 40 is fixed by means of a card point and a card slot, a card point and a card point, etc. During assembly, the inner liner is installed first, and then the material is filled into the powder tray 40. After filling, the inner liner is installed in the bottom assembly. During the process of filling the material, if a defect occurs due to misoperation, it is only necessary to remove the powder tray 40 alone and replace it with a new one. Since the powder tray and the middle ring are detachable, when filling the cosmetic material, if the filling is unqualified, it is only necessary to replace the powder tray without scrapping the middle ring and the powder tray as a whole, thereby reducing the cost of scrapping and damage during the filling process and reducing the waste of resources.

[0056] In this liner, the mesh 36 can be welded to the first mounting portion 37, and the mesh and the first mounting portion can be supported by the second mounting portion 41, so as to avoid the mesh 36 from falling off when the mesh 36 is pressed, so that the light and thin function can be achieved while satisfying the structural strength of the mesh. Of course, the mesh can also be not installed in the liner, but a sponge for absorbing and containing the material body can be used in the powder tray. Therefore, the liner has two usage methods. One method is to set a mesh at the opening of the powder tray and fill the powder tray with cosmetic materials. The other method is to set a sponge for absorbing and containing the material body in the powder tray without a mesh, thereby broadening the scope of use of the liner.

[0057] In the present application, the ratio of the thickness of the inner cover to the thickness of the powder tray is controlled within the range of 0.7 to 1.1 in order to ensure that the powder tray, the middle ring and the inner cover have sufficient wall thickness and strength when the overall thickness of the product is relatively thin, and to also make the capacity of the powder tray moderate.

[0058] like Figure 3 and Figure 4 As shown, the mesh cloth 36 is fixedly mounted on the first mounting portion 37, and the first mounting portion 37 and the second mounting portion 41 clamp the mesh cloth 36, the first mounting portion 37 is fixedly connected to the middle circle 30; or, the first mounting portion 37 and the middle circle 30 are integrally formed; the second mounting portion 41 is fixedly connected to the powder tray 40; or, the second mounting portion 41 and the powder tray 40 are integrally formed; the thickness L4 of the first mounting portion 37 is 0.6 mm to 1.0 mm.

[0059] like Figure 8 As shown, optionally, the thickness L4 of the first mounting portion 37 is 0.85 mm. Figure 4 As shown, in a possible embodiment, the first mounting portion 37 is integrally formed with the middle ring 30, the second mounting portion 41 is integrally formed with the powder tray 40, the mesh 36 is welded to the first mounting portion 37, and when the powder tray 40 is clamped to the middle ring 30, the edge of the mesh 36 is located in the gap between the first mounting portion 37 and the second mounting portion 41, the first mounting portion 37 and the second mounting portion 41 clamp the mesh, and the second mounting portion 41 is used to support the mesh 36 and the first mounting portion 37, that is, the second mounting portion 41 plays a role of support and structural reinforcement, thereby preventing the mesh 36 from falling off when the mesh 36 is pressed. In this application, the first mounting portion and the second mounting portion are used to support the mesh, so that the light and thin function can be achieved while meeting the structural strength of the mesh.

[0060] like Figure 6As shown, the thickness L1 of the liner is 15mm to 18mm, the thickness L2 of the inner cover 10 is 5.5mm to 8.5mm, the thickness L3 of the powder tray 40 is 6mm to 9mm, and the ratio of L2 to L3 is 0.8 to 1.0. In a possible embodiment, the thickness L1 of the liner is 16, the thickness L2 of the inner cover 10 is 6.9mm, the thickness L3 of the powder tray 40 is 7.5mm, and the ratio of L2 to L3 is 0.92.

[0061] like Figure 6 and Figure 8 As shown, the volume V of the powder tray 40 is 10 mL to 15 mL, and the thickness L5 of the inner space of the powder tray 40 is 5 mm to 7 mm. The inner space of the powder tray 40 is used to store cosmetic materials or sponges.

[0062] like Fig.10 and Fig.11 As shown, the bottom surface of the inner cover 10 is inwardly concave to form a receiving space 13, and the thickness L6 of the receiving space 13 is 0.4mm to 0.7mm. That is, the bottom surface of the inner cover 10 is an arc-shaped surface, and the thickness of the receiving space 13 refers to the thickness of the deepest area of ​​the bottom surface of the inner cover 10 concave inward. Figure 4 As shown, before the inner liner is used, the upper opening of the powder tray 40 covers the sealing layer 42. After the powder tray is filled with cosmetic materials, the sealing layer will bulge upward in an arch shape, and the accommodating space 13 provides an escape space for the bulging of the sealing layer, thereby preventing the sealing layer from lifting up the inner cover 10 after swelling.

[0063] There is an exhaust channel between the sealing ring 20 and the middle ring 30. When the inner cover 10 is covered on the middle ring 30, the exhaust channel is used to discharge the gas inside the middle ring 30. When the inner cover 10 is opened, the exhaust channel is used to allow external gas to enter the middle ring 30. The sealing ring 20 is sealed in the middle ring 30 to achieve the airtight function of the powder tray 40, wherein the powder tray 40 stores cosmetic materials. A part of the sealing ring 20 is airtightly attached to the middle ring 30, thereby sealing the powder tray 40 below the middle ring 30, so that external air cannot enter the powder tray 40; another part of the sealing ring 20 forms an exhaust channel with the middle ring 30. When the inner cover 10 is closed and opened, the exhaust channel is used for the circulation of gas inside and outside the middle ring 30, and after the inner cover is completely closed, the exhaust channel will not affect the sealing effect of the sealing ring.

[0064] When the inner cover 10 is closed, the air between the sealing ring 20 and the middle ring 30 can be discharged through the exhaust channel. Similarly, when the inner cover 10 is opened, the outside air can enter between the middle ring 30 and the sealing ring 20 through the exhaust channel, thereby eliminating the internal and external pressure difference between the sealing ring 20 and the middle ring 30, which is convenient for the smooth opening and closing of the inner cover. In this application, the sealing ring is used to seal the inner cover and the middle ring to achieve the purpose of sealing the powder tray, thereby avoiding the situation where the cosmetic materials stored in the container are contaminated due to long-term contact with the outside air; the exhaust channel is used to facilitate the circulation of the internal and external gases of the middle ring, so as to achieve the effect of facilitating the opening and closing of the inner cover, thereby improving the consumer's consumption experience. Therefore, this application has an exhaust function while ensuring the sealing effect, and has strong practicality.

[0065] There is an airtight fitting area between the sealing ring 20 and the middle ring 30. Optionally, in the airtight fitting area, the sealing ring 20 and the middle ring 30 are interference fit, and the exhaust channel is located on the side of the airtight fitting area away from the powder tray 40. Figure 1 As shown, the powder tray 40 is located at the lower side of the airtight fitting area, and the exhaust channel is located at the upper side of the airtight fitting area, thereby ensuring that the exhaust channel will not affect the airtight effect between the sealing ring 20 and the middle ring 30.

[0066] like Figure 1 and Figure 2 As shown, the outer wall of the sealing ring 20 extends radially outward to form an annular protrusion 21, and the inner wall of the middle ring 30 is recessed inward to form an annular groove 34. The annular protrusion 21 is interference-fitted in the annular groove 34, and the annular protrusion 21 and the annular groove 34 are located in an airtight fitting area. The sealing effect of the sealing ring 20 can be further improved by using the annular protrusion 21 and the annular groove 34 that cooperate with each other.

[0067] The exhaust channel includes an exhaust groove 33 , and N exhaust grooves 33 are provided between the sealing ring 20 and the middle ring 30 , wherein N≧1 and N is an integer. In a possible implementation manner, the exhaust groove 33 is provided on the outer side wall of the sealing ring 20 .

[0068] In another possible implementation, the exhaust groove 33 is provided on the inner side wall of the middle ring 30. Fig.16 and Fig.17 As shown, in this embodiment, the exhaust groove 33 is provided on the middle ring 30, that is, the inner wall of the middle ring 30 is provided with the exhaust groove 33 along the circumferential direction, and the exhaust groove 33 passes through the upper end surface of the middle ring 30. The exhaust groove 33 is provided on the inner wall of the middle ring 30, which improves the overall aesthetics of the product. Fig.17As shown, the exhaust groove 33 is located above the annular groove 34. When the inner cover 10 is covered on the middle ring 30, the air between the sealing ring 20 and the middle ring 30 is discharged to the outside of the middle ring through the exhaust groove 33, so that the inner cover is completely closed in the middle ring. After the inner cover is covered with the middle ring, since the annular groove 34 of the middle ring and the annular protrusion 21 of the sealing ring are located below the exhaust groove 33, the exhaust groove will not affect the sealing effect of the sealing ring.

[0069] Optionally, the sealing ring 20 is made of thermoplastic elastomer material TPE material, the inner cover 10 and the middle ring 30 are made of polyolefin material, and the hardness of the sealing ring 20 is less than that of the inner cover 10 and the middle ring 30. Fig.13 and Fig.14 As shown, the sealing ring 20 is located at the lower end surface of the inner cover 10. The sealing ring 20 is made of elastic material, and the inner cover 10 and the sealing ring 20 are integrally formed by two-color injection molding. The inner cover 10 and the sealing ring 20 are integrally formed by injection molding, so the bonding strength between the inner cover and the sealing ring is high and the sealing effect is good.

[0070] like Figure 1 and Figure 2 As shown, the sealing ring 20 includes an annular structure with openings at both ends, and the inner wall of the sealing ring 20 is combined with the outer wall of the inner cover 10 .

[0071] like Fig.16 and Fig.17 As shown, the middle ring 30 is fixed with a first cylinder 31 and a second cylinder 32, the second cylinder 32 is located outside the first cylinder 31, the exhaust channel is located between the sealing ring 20 and the inner wall of the first cylinder 31, the sealing ring 20 is airtightly attached to the inner wall of the first cylinder 31, and the second cylinder 32 is fixedly engaged with the inner cover 10. Optionally, the exhaust groove 33 is opened on the inner wall of the first cylinder 31. Fig.10 As shown, there is a gap between the first cylinder 31 and the second cylinder 32, the inner cover 10 is inserted into the gap, and the outer wall of the inner cover 10 is engaged with the inner wall of the second cylinder 32, and the outer wall of the sealing ring 20 is airtightly fitted with the inner wall of the first cylinder 31.

[0072] like Figure 1-9 As shown, the inner cover 10 is rotatably mounted on the middle ring 30 through the first hinge assembly, the inner cover 10 is fixedly engaged with the middle ring 30, and the powder tray 40 is fixedly engaged with the middle ring 30. The first hinge assembly includes a first hinge 11, a second hinge 35 and a first hinge shaft 12. Fig.14 As shown, the first hinge 11 is fixedly mounted on the inner cover 10. Fig.16 and Fig.17 As shown, the second hinge 35 is fixedly mounted on the middle ring 30. Fig.10As shown, during assembly, after the first hinge 11 and the second hinge 35 are butted, the first hinge shaft 12 is inserted into the first hinge 11 and the second hinge 35 to rotatably connect the inner cover 10 and the middle ring 30. Figure 1 As shown, the inner cover 10 and the middle ring 30 are fixed by means of clamping points and clamping grooves, clamping points and clamping points, etc.

[0073] like Figure 1 and Fig. 9 As shown, the cosmetic container further includes a bottom assembly and an outer cover 50 . The cosmetic liner is detachably connected to the bottom assembly. The outer cover 50 is rotatably mounted on the bottom assembly via a second hinge assembly. The outer cover 50 can cover the inner cover 10 .

[0074] The bottom assembly includes an outer sole 70 and an inner sole 60 fixedly installed in the outer sole 70, and the middle ring 30 is detachably installed inside the inner sole 60. The inner sole 60 and the outer sole 70 are fixed by means of a clamping point and a clamping groove, a clamping point and a clamping point, etc.; the middle ring 30 and the inner sole 60 are fixed by means of a clamping point and a clamping groove, a clamping point and a clamping point, etc.

[0075] The inner cover 10, the middle ring 30 and the powder tray 40 form an inner container. When the material in the powder tray 40 is used up, the inner container is removed and replaced with a new one for continued use. Therefore, other components in the cosmetic container can be reused, which is energy-saving, environmentally friendly and cost-saving. When assembling, the inner container is first installed, and then the material is filled into the powder tray 40. After filling, the inner container is installed in the bottom assembly. During the process of filling the material, if a defect occurs due to misoperation, it is only necessary to remove the powder tray 40 separately and replace it with a new one.

[0076] The lower surface of the powder tray 40 may be partially exposed to the outside or the lower surface of the powder tray 40 may be completely exposed to the outside. When the lower surface of the powder tray 40 is partially exposed to the outside, the powder tray 40 can be lifted upward from the lower end of the container to separate the entire inner liner from the top and the bottom assembly; when the lower surface of the powder tray 40 is completely exposed to the outside, the inner liner can be pressed directly from the top of the container to separate the entire inner liner from the bottom and the bottom assembly. Therefore, the disassembly of the inner liner is very convenient.

[0077] like Figure 1 and Fig. 9 As shown, the second hinge assembly includes a third hinge 51, a fourth hinge 71 and a second hinge shaft 52. Fig. 9 As shown, the third hinge 51 is fixedly mounted on the outer cover 50, and the fourth hinge 71 is fixedly mounted on the outer bottom 70. Figure 1 As shown, during assembly, after the third hinge 51 and the fourth hinge 71 are connected, the second hinge shaft 52 is inserted into the third hinge 51 and the fourth hinge 71 to rotatably connect the outer cover 50 to the outer bottom 70. Optionally, the inner side of the outer cover 50 is fixedly fitted with the lens 54, and the inner cover 10 is placed with a powder puff for dipping the cosmetic material.

[0078] like Figure 5-8 As shown, the overall thickness L7 of the cosmetic container is 15mm to 20mm, the inner diameter D1 of the powder tray 40 is 40mm to 60mm, and the ratio between L7 and D1 is 0.2 to 0.5, the outer diameter D2 of the outer cover 50 is 60mm to 90mm, the thickness L8 is 6.5mm to 10.5mm, and the thickness L9 of the outer bottom 70 is 8mm to 14mm.
