[0008] Selectively, the bottom surface of the inner lid is recessed inward to form a storage space, and the thickness L6 of the storage space is 0.4 mm to 0.7 mm.

[0009] Selectively, there is an exhaust passage between the seal ring and the intermediate ring, and in the process of the inner lid covering the intermediate ring, the exhaust passage is used to discharge gas from inside the intermediate ring, and in the process of opening the inner lid, the exhaust passage is used to allow outside air to enter inside the intermediate ring.

[0010] The seal ring and the middle ring are optionally provided with an airtight sealing region, and the exhaust passage is located on the side of the airtight sealing region away from the powder container.

[0011] Selectively, the outer wall of the seal ring extends radially outward to form an annular projection, the inner wall of the middle ring is recessed inward to form an annular groove, the annular projection is joined to the annular groove by interference fit, and the annular projection and the annular groove are located in the airtight joint region.

[0012] Selectively, the exhaust passage includes exhaust grooves, with N exhaust grooves provided between the seal ring and the intermediate wheel, wherein the exhaust grooves are opened in the outer wall of the seal ring, or the exhaust grooves are opened in the inner wall of the intermediate wheel, where N ≥ 1, and N is an integer.

[0013] Selectively, the seal ring is made of TPE material, the inner lid and the middle ring are made of polyolefin material, and the hardness of the seal ring is less than the hardness of the inner lid and the middle ring.

[Effects of the Invention]

[0017] The beneficial effects of this application are as follows: 1) In this container, the ratio of the thickness of the inner lid to the thickness of the powder container is controlled within the range of 0.7 to 1.1. That is, by designing a reasonable ratio between the thickness of the inner lid and the thickness of the powder container, it is ensured that the powder container, inner ring, and inner lid have sufficient thickness and strength even when the overall thickness of the product is thin, and the capacity of the powder container can be appropriately adjusted.

When the powder container is locked to the middle ring, the edge of the mesh cloth is positioned in the gap between the first mounting portion and the second mounting portion, and the mesh cloth is clamped by the first and second mounting portions. The second mounting portion is used to support the mesh cloth and the first mounting portion. That is, the second mounting portion plays a role in support and structural reinforcement, preventing the mesh cloth from falling off when pressed. In this application, since the mesh cloth is supported using the first and second mounting portions, it is possible to achieve a lightweight function while satisfying the structural strength required to attach the mesh cloth. 3) In this invention, since the powder container is removable from the inner wheel, if a filling defect occurs when filling cosmetic materials, only the powder container needs to be replaced, and there is no need to discard the entire inner wheel and powder container, thereby reducing the cost of disposal and damage during the filling process and reducing the waste of resources. 4) In the present application, an exhaust passage is provided between the seal ring and the middle ring, and the exhaust passage is used for the flow of gas inside and outside the middle ring. During the closing process of the inner lid, the air between the seal ring and the middle ring can be discharged in a timely manner through the exhaust passage. During the opening process of the inner lid, outside air enters the area between the middle ring and the seal ring through the exhaust passage, thereby eliminating the internal and external pressure difference in the area between the seal ring and the middle ring and facilitating the smooth opening and closing of the inner lid. In the present application, by using a seal ring to seal between the inner lid and the middle ring, the purpose of sealing the powder container is achieved, and it is avoided that cosmetic materials are stored in the container and contaminated by contact with outside air for a long time.

[0019] The following describes the technical aspects of the embodiments of the present application clearly and completely. Clearly, the embodiments described herein represent only a portion of the embodiments, not all of them. All other embodiments obtained by a person skilled in the art without any creative work based on the embodiments of the present application are all within the scope of protection of the present application.

[0020] Furthermore, the terms "First," "Second," etc., in the specification, claims, and drawings of this application are not intended to describe a specific order or priority, but rather to distinguish similar objects. It should be understood that objects used in this manner are interchangeable where appropriate, so that the embodiments of this application described herein may be carried out, for example, in an order other than those illustrated or described herein. Moreover, the terms "includes" and "has," and all their variations, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus including a series of steps or units may include steps or units not explicitly listed, or other steps or units specific to those processes, methods, products, or apparatus.

[0021] For the sake of clarity, spatial relative terms such as "on top of," "above," "on the top surface of," and "on the top surface" are used here to describe the spatial positional relationship between one device or feature and another device or feature, as shown in the diagram. It should be understood that spatial relative terms are intended to allow for different orientations in use or operation other than the orientation described in the diagram. For example, if the device in the drawing is upside down, a device described as "above another device or structure" or "above another device or structure" may later be positioned as "below another device or structure" or "below another device or structure." Therefore, the exemplary term "above" may include two orientations: "above" and "below." The device may also be positioned in other different ways (90-degree rotation or other orientations), and the spatial relative descriptions used here should be appropriately explained.

[0022] Example 1: As shown in Figures 1-19, the cosmetic container includes a lightweight cosmetic inner container. The inner container includes an inner lid 10, a middle ring 30, and a powder container 40. The powder container 40 is removably mounted inside the middle ring 30, and a seal ring 20 is fixedly provided on the inner lid 10. The seal ring 20 can seal the middle ring 30 by interference fit between the seal ring 20 and the middle ring 30. A first mounting portion 37 is provided at the top of the opening of the powder container 40, and a second mounting portion 41 is provided below the first mounting portion 37, with a gap between the first mounting portion 37 and the second mounting portion 41. As shown in Figure 6, the thickness L1 of the inner container is 13mm to 19mm, the thickness of the inner lid 10 is L2, and the thickness of the powder container 40 is L3, with the ratio of L2 to L3 being 0.7 to 1.1.

[0023] The powder container 40 is selectively engaged and fixed in a manner such as engagement point to engagement groove, engagement point to engagement point, etc. When assembling, first attach the inner container, then fill the powder container 40 with material, and after filling, attach the inner container to the bottom assembly. If a defect occurs due to an error during the material filling process, the powder container 40 can be removed individually and replaced with a new powder container. Because the powder container is detachable from the middle wheel, if a filling defect occurs when filling cosmetic material, only the powder container needs to be replaced, and there is no need to discard the middle wheel and the entire powder container, thus reducing the cost of disposal damage during the filling process and reducing resource waste.

[0024] In this container, the mesh cloth 36 is welded to the first mounting portion 37, and the mesh cloth and the first mounting portion are supported by the second mounting portion 41. This prevents the mesh cloth 36 from falling off when pressed, thus achieving a lightweight function while satisfying the structural strength required for attaching the mesh cloth. Of course, this container can also be used as a powder container without attaching the mesh cloth, by using a sponge that absorbs and contains the material. Therefore, this container has two usage methods: one in which a mesh cloth is installed at the opening of the powder container and cosmetic materials are filled into the powder container, and another in which a sponge that absorbs and contains the material is used as the powder container without installing the mesh cloth, thereby expanding the range of use of this container.

[0025] In this application, in order to ensure that the powder container, middle ring, and inner lid have sufficient thickness and strength when the overall thickness of the product is thin, and to ensure that the capacity of the powder container is also appropriate, the ratio of the thickness of the inner lid to the thickness of the powder container is controlled to a range of 0.7 to 1.1.

[0026] As shown in Figures 3 and 4, a mesh cloth 36 is fixedly attached to 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 wheel 30, or the first mounting portion 37 is integrally molded with the middle wheel 30. The second mounting portion 41 is fixedly connected to the powder container 40, or the second mounting portion 41 is integrally molded with the powder container 40. The thickness L4 of the first mounting portion 37 is 0.6 mm to 1.0 mm.

[0027] As shown in Figure 8, the thickness L4 of the first mounting portion 37 is optionally 0.85 mm. As shown in Figure 4, in one possible embodiment, the first mounting portion 37 is integrally molded with the middle wheel 30, the second mounting portion 41 is integrally molded with the powder container 40, and the mesh cloth 36 is welded to the first mounting portion 37. When the powder container 40 is locked to the middle wheel 30, the edge of the mesh cloth 36 is positioned in the gap between the first mounting portion 37 and the second mounting portion 41, clamping the mesh cloth between the first mounting portion 37 and the second mounting portion 41. The second mounting portion 41 is used to support the mesh cloth 36 and the first mounting portion 37. That is, the second mounting portion 41 serves as support and structural reinforcement, preventing the mesh cloth 36 from falling off when pressed. In this invention, the mesh fabric is supported using the first mounting portion and the second mounting portion, thereby achieving a lightweight function while satisfying the structural strength required for attaching the mesh fabric.

[0028] As shown in Figure 6, the thickness L1 of the inner container is 15 mm to 18 mm, the thickness L2 of the inner lid 10 is 5.5 mm to 8.5 mm, and the thickness L3 of the powder container 40 is 6 mm to 9 mm, with a ratio of L2 to L3 of 0.8 to 1.0. In one possible embodiment, the thickness L1 of the inner container is 16 mm, the thickness L2 of the inner lid 10 is 6.9 mm, and the thickness L3 of the powder container 40 is 7.5 mm, with a ratio of L2 to L3 of 0.92.

[0029] As shown in Figures 6 and 8, the volume V of the powder container 40 is 10 mL to 15 mL, and the thickness L5 of the internal space of the powder container 40 is 5 mm to 7 mm. The internal space of the powder container 40 is used to contain cosmetic materials or sponges.

[0030] As shown in Figures 10 and 11, the bottom surface of the inner lid 10 is recessed inward to form a storage space 13, and the thickness L6 of the storage space 13 is 0.4 mm to 0.7 mm. That is, the bottom surface of the inner lid 10 has an arc shape, and the thickness of the storage space 13 refers to the thickness of the area where the bottom surface of the inner lid 10 is most deeply recessed inward. As shown in Figure 4, before use of the inner container, the upper opening of the powder container 40 covers the sealing layer 42, and when cosmetic material is filled into the powder container, the sealing layer bulges upward and forms an arch. The storage space 13 provides a space to escape the bulging of the sealing layer and prevents the inner lid 10 from being pushed up after the sealing layer bulges.

[0031] An exhaust passage is provided between the seal ring 20 and the middle ring 30. During the process of closing the inner lid 10 over the middle ring 30, the exhaust passage is used to expel gas from inside the middle ring 30, and during the process of opening the inner lid 10, the exhaust passage is used to allow outside air to enter the middle ring 30. The seal ring 20 is sealed over the middle ring 30 to achieve an airtight function of the powder container 40 in which the cosmetic material is stored. A portion of the seal ring 20 is airtightly joined to the middle ring 30 to seal the powder container 40 below the middle ring 30, preventing outside air from entering the powder container 40. An exhaust passage is formed between the other portion of the seal ring 20 and the middle ring 30. During the opening and closing process of the inner lid 10, the exhaust passage is used for the flow of gas between the inside and outside of the middle ring 30. Moreover, when the inner lid is completely closed, the exhaust passage does not affect the sealing effect of the seal ring.

[0032] During the closing process of the inner lid 10, the air between the seal ring 20 and the middle ring 30 can be discharged through the exhaust passage. Similarly, during the opening process of the inner lid 10, outside air can enter the space between the middle ring 30 and the seal ring 20 through the exhaust passage. This eliminates the pressure difference between the inside and outside of the area between the seal ring 20 and the middle ring 30, facilitating the smooth opening and closing of the inner lid. In this invention, the purpose of sealing the powder container is achieved by sealing the space between the inner lid and the middle ring using the seal ring, preventing contamination of cosmetic materials stored in the container due to prolonged contact with outside air. By utilizing the exhaust passage, the flow of outside air between the inside of the middle ring is facilitated, achieving the effect of facilitating the opening and closing of the inner lid and enhancing the consumer experience. Therefore, this invention guarantees a sealing effect and has an exhaust function, making it highly practical.

[0033] A hermetically sealed joint region is provided between the seal ring 20 and the intermediate ring 30. Optionally, in the hermetically sealed joint region, the seal ring 20 and the intermediate ring 30 are joined by an interference fit. The exhaust passage is located on the side of the hermetically sealed joint region away from the powder container 40. As shown in Figure 1, the powder container 40 is located below the hermetically sealed joint region, and the exhaust passage is located above the hermetically sealed joint region. This ensures that the exhaust passage does not affect the airtight seal between the seal ring 20 and the intermediate ring 30.

[0034] As shown in Figures 1 and 2, the outer wall of the seal ring 20 extends radially outward to form an annular projection 21, and the inner wall of the middle ring 30 is recessed inward to form an annular groove 34. The annular projection 21 is joined to the annular groove 34 by interference fit, and the annular projection 21 and the annular groove 34 are located in an airtight joint region. The interlocking annular projection 21 and the annular groove 34 further enhance the sealing effect of the seal ring 20.

[0035] The exhaust passage includes exhaust grooves 33. N exhaust grooves 33 are provided between the seal ring 20 and the middle ring 30, where N ≥ 1, and N is an integer. In one possible embodiment, the exhaust grooves 33 are opened in the outer wall of the seal ring 20.

[0036] In another possible embodiment, the exhaust groove 33 is provided in the inner wall of the middle wheel 30. As shown in Figures 16 and 17, in this embodiment, the exhaust groove 33 is provided in the middle wheel 30. That is, the inner wall of the middle wheel 30 has an exhaust groove 33 provided in the circumferential direction, and the exhaust groove 33 penetrates the upper end surface of the middle wheel 30. Providing the exhaust groove 33 in the inner wall of the middle wheel 30 enhances the overall appearance of the product. As shown in Figure 17, the exhaust groove 33 is located above the annular groove 34. During the process of the inner lid 10 covering the middle wheel 30, the air between the seal ring 20 and the middle wheel 30 is discharged to the outside of the middle wheel through the exhaust groove 33, facilitating the inner lid to be completely closed onto the middle wheel. When the inner lid covers the middle wheel, the annular groove 34 of the middle wheel and the annular projection 21 of the seal ring are located below the exhaust groove 33, so the exhaust groove does not affect the sealing effect of the seal ring.

[0037] Selectively, the seal ring 20 is made of a thermoplastic elastomer material (TPE), while the inner lid 10 and middle ring 30 are made of polyolefin material, and the hardness of the seal ring 20 is less than that of the inner lid 10 and middle ring 30. As shown in Figures 13 and 14, the seal ring 20 is located on the lower end surface of the inner lid 10, and the seal ring 20 is made of an elastic material, and the inner lid 10 and seal ring 20 are integrally molded by two-color injection molding. Because the inner lid 10 and seal ring 20 are integrally molded by injection molding, the bonding strength between the inner lid and the seal ring is high, resulting in a high sealing effect.

[0038] As shown in Figures 1 and 2, the seal ring 20 includes an annular structure with openings at both the upper and lower ends, and the inner wall of the seal ring 20 is coupled to the outer wall of the inner lid 10.

[0039] As shown in Figures 16 and 17, the intermediate wheel 30 is fixedly provided with a first cylindrical body 31 and a second cylindrical body 32, the second cylindrical body 32 is located outside the first cylindrical body 31, the exhaust passage is located between the seal ring 20 and the inner wall of the first cylindrical body 31, the seal ring 20 is airtightly joined to the inner wall of the first cylindrical body 31, and the second cylindrical body 32 and the inner lid 10 are engaged and fixed. Optionally, an exhaust groove 33 is provided in the inner wall of the first cylindrical body 31. As shown in Figure 10, there is a gap between the first cylindrical body 31 and the second cylindrical body 32, the inner lid 10 is inserted into the gap, the outer wall of the inner lid 10 engages with the inner wall of the second cylindrical body 32, and the outer wall of the seal ring 20 is airtightly joined to the inner wall of the first cylindrical body 31.

[0040] As shown in Figures 1 to 9, the inner lid 10 is rotatably mounted on the middle wheel 30 via a first hinge assembly, and the inner lid 10 and the middle wheel 30 are engaged and fixed together, and the powder container 40 and the middle wheel 30 are engaged and fixed together. The first hinge assembly includes a first hinge 11, a second hinge 35, and a first hinge shaft 12. As shown in Figure 14, the first hinge 11 is fixedly mounted to the inner lid 10, and as shown in Figures 16 and 17, the second hinge 35 is fixedly mounted to the middle wheel 30. As shown in Figure 10, during assembly, after the first hinge 11 and the second hinge 35 are butted together, the first hinge shaft 12 is drilled into the first hinge 11 and the second hinge 35, rotatably connecting the inner lid 10 and the middle wheel 30. As shown in Figure 1, the powder container 40 and the middle wheel 30 are engaged and fixed together by locking points and locking grooves, locking points and locking points, etc.

[0041] As shown in Figures 1 and 9, the cosmetic container further includes a bottom assembly that is removably connected to the cosmetic inner container, and an outer lid 50 that is rotatably attached to the bottom assembly via a second hinge assembly and can cover the inner lid 10.

[0042] The bottom assembly includes an outer bottom 70 and an inner bottom 60 fixedly mounted within the outer bottom 70, with the middle wheel 30 removably mounted inside the inner bottom 60. The inner bottom 60 and the outer bottom 70 are engaged and fixed by locking points and locking grooves, locking points and locking points, etc., and the middle wheel 30 is engaged and fixed between the inner bottom 60 by locking points and locking grooves, locking points and locking points, etc.

[0043] The inner lid 10, middle ring 30, and powder container 40 constitute the inner container. After the material in the powder container 40 is used up, the inner container can be removed and replaced with a new inner container for continued use, allowing other parts of the cosmetic container to be reused, resulting in energy savings, environmental friendliness, and cost savings. When assembling, first attach the inner container, then fill the powder container 40 with material, and after filling, attach the inner container to the bottom assembly. If a defect occurs due to an error during the material filling process, simply remove the powder container 40 separately and replace it with a new powder container.

[0044] The bottom surface of the powder container 40 can be partially exposed to the outside, or it can be completely exposed to the outside. When the bottom surface of the powder container 40 is partially exposed to the outside, the powder container 40 can be pushed upward from the bottom end of the container, allowing the entire inner container to be detached from the bottom assembly from above. When the bottom surface of the powder container 40 is completely exposed to the outside, the inner container can be pressed directly from above the container, allowing the entire inner container to be detached from the bottom assembly from below. Therefore, removing the inner container is very convenient.

[0045] As shown in Figures 1 and 9, the second hinge assembly includes a third hinge 51, a fourth hinge 71, and a second hinge shaft 52. As shown in Figure 9, the third hinge 51 is fixedly attached to the outer lid 50, and the fourth hinge 71 is fixedly attached to the outer bottom 70. As shown in Figure 1, during assembly, after the third hinge 51 and the fourth hinge 71 are butted together, the second hinge shaft 52 is drilled into the third hinge 51 and the fourth hinge 71, rotatably connecting the outer lid 50 and the outer bottom 70. Optionally, a mirror 54 is fixedly attached to the inside of the outer lid 50, and a puff for applying cosmetic materials is positioned on the inner lid 10.

[0046] As shown in Figures 5-8, the overall thickness L7 of the cosmetic container is 15mm-20mm, the inner diameter D1 of the powder container 40 is 40mm-60mm, the ratio of L7 to D1 is 0.2-0.5, the outer diameter D2 of the outer lid 50 is 60mm-90mm, the thickness L8 is 6.5mm-10.5mm, and the thickness L9 of the outer bottom 70 is 8mm-14mm. Controlling the ratio of L7 to D1 within the range of 0.2-0.5 ensures the capacity of the cosmetic container while simultaneously ensuring that the powder container and inner ring have sufficient wall thickness and strength. If the ratio is too large, the capacity of the container will be small and will not meet the user needs. If the ratio is too small, the wall thickness of the powder container and inner ring will be too small, resulting in insufficient strength for the powder container and inner ring, and making it difficult to attach mesh cloth to the inner ring.

[0047] In one specific embodiment, the overall thickness L7 of the cosmetic container is 19.85 mm, the outer diameter D2 of the outer lid 50 is 74.2 mm, the thickness L8 is 8.45 mm, the thickness L9 of the outer bottom 70 is 11.3 mm, the overall thickness L1 of the inner container is 16 mm, the thickness L2 of the inner lid is 6.9 mm, the thickness L3 of the powder container is 7.5 mm, the inner diameter D1 is 50.52 mm, the thickness L4 of the internal space of the powder container is 6 mm, and the ratio of L7 to D1 is 0.4. The overall thickness dimension of this cosmetic container is controlled to be within 20 mm, and because the container is made of thermoplastic material, the overall thickness is thin, the weight is light, and it is convenient to use and carry.

[0048] In Embodiment 1, as shown in Figures 1 and 9, the outer cover 50 and the outer bottom 70 are engaged and fixed by an engagement assembly. The engagement assembly includes a button 72 and a groove 53. The button 72 is mounted inside the outer bottom 70 and is provided with a locking hook 73. A groove 53 is provided in the inner wall of the outer cover 50, and the locking hook 73 engages with the groove 53 to engage and fix the outer cover 50 and the outer bottom 70. An elastic piece is fixed to the button 72. When in use, pressing the button 72 deforms the elastic piece and further disengages the locking hook 73 from the groove 53, thereby opening the outer cover 50. When the button is released, the button 72 is reset by the elastic piece. A rear engagement member 74 is provided between the outer cover 50 and the outer bottom 70.

[0049] In Examples 2 and 3, the outer lid 50 and the outer bottom portion 70 are fixed together by suction using an adsorption member.

[0050] Example 2: As shown in Figure 20, the suction assembly includes a first magnet 55 and a second magnet 75. The first magnet 55 is mounted inside the outer lid 50, and the second magnet 75 is mounted inside the outer bottom 70, and the outer lid 50 and the outer bottom 70 are fixed by mutual attraction between the first magnet 55 and the second magnet 75. A mesh cloth 36, which is located above the powder container 40, is welded to the middle wheel 30. In this embodiment, the use of the first magnet 55 and the second magnet 75 instead of the conventional engaging member makes operation more convenient.

[0051] Example 3: As shown in Figure 21, the adsorption assembly includes a magnetic metal member 56 and a second magnet 75. The second magnet 75 is attached to either the outer lid 50 or the outer bottom 70, and the magnetic metal member 56 is attached to the other of the outer lid 50 or the outer bottom 70, and the outer lid 50 and the outer bottom 70 are adsorbed and fixed by mutual attraction between the second magnet 75 and the magnetic metal member 56. The magnetic metal member 56 is made of a ferromagnetic material. Ferromagnetic materials include materials such as iron, cobalt, and nickel, and alloys of iron, cobalt, and nickel. In this embodiment, the second magnet 75 and the magnetic metal member 56 are used instead of an engagement assembly. In Figure 13, the magnetic metal member 56 is attached inside the outer lid 50, and the second magnet 75 is attached to the outer bottom 70. Of course, the second magnet 75 may be attached inside the outer lid 50, and the magnetic metal 56 may be attached inside the outer bottom 70.

[0052] In this application, the outer cover 50 and the outer bottom portion 70 are engaged and fixed by an engagement assembly or by suction and fixed by an adsorption assembly, so the connection method between the two is simple, reliable, low-cost, and easy to use.

[0053] Those skilled in the art should point out that several modifications and improvements can be made without departing from the concept of the present application, and that these fall within the scope of protection of the present application. Therefore, the scope of protection of the present application must be in accordance with the claims for registration of the utility model attached. [Explanation of Symbols]
