SPECIFIC IMPLEMENTATIONS

[0026] The following describes the technical solutions in the embodiments of the present disclosure clearly and completely with reference to the embodiments of the present disclosure. Apparently, the embodiments described are merely some rather than all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0027] It should be noted that the terms "first", "second" and so on in the description and claims of the present disclosure and in the above accompanying drawings are intended to distinguish similar objects but do not necessarily indicate a specific order or sequence. It should be understood that the objects used in such a way may be exchanged under proper conditions to make it possible to implement the described implementations of the present disclosure in sequences except those illustrated or described herein. Moreover, the terms "include", "have" and their variants mean to cover a non-exclusive inclusion. For example, a process, method, system, product or device that includes a list of steps or units is not necessarily limited to those steps or units which are clearly listed. Instead, they may include other steps or units which are not expressly listed or inherent to such a process, method, product, or device.

[0028] For ease of description, spatially relative terms, such as "above", "on the upper side of", "on the upper surface of" and "on", can be used to describe the spatial positional relationship between components or features shown in the figure. It should be understood that the spatially relative terms are intended to encompass different orientations of the components in use or operation in addition to those shown in the figure. For example, if a component in the figure is inverted, it is described as a component "above other component or structure" or "on other component or structure". Therefore, the component will be positioned as "below other component or structure" or "under other component or structure". Therefore, the exemplary term "above" may include both orientations "above" and "below". The component may also be positioned in other different ways (rotated by 90 degrees or in other orientations), but the relative description of the space should be explained accordingly.

[0029] Embodiment 1: As shown in FIGS. 1-13, a cosmetic container includes a cosmetic cartridge. The cosmetic cartridge includes: inner cap 10, intermediate ring 30, and powder pan 40. The powder pan 40 is fixedly disposed in the intermediate ring 30. Sealing ring 20 is fixedly disposed on the inner cap 10. The sealing ring 20 is in interference fit with the intermediate ring 30, such that the sealing ring 20 can seal the intermediate ring 30. An exhaust passage is formed between the sealing ring 20 and the intermediate ring 30. When the inner cap 10 is closed onto the intermediate ring 30, the exhaust passage is configured to exhaust air from the intermediate ring 30. When the inner cap 10 is opened, the exhaust passage is configured to allow outside air to enter the intermediate ring 30. The sealing ring 20 is configured to seal the intermediate ring 30, so as to achieve a hermetic function of the powder pan 40. A cosmetic material is stored in the powder pan 40. One portion of the sealing ring 20 is hermetically attached to the intermediate ring 30 to seal the powder pan 40 under the intermediate ring 30, such that outside air cannot enter the powder pan 40. The exhaust passage is formed between the other portion of the sealing ring 20 and the intermediate ring 30. When the inner cap 10 is closed and opened, the exhaust passage is configured to realize circulation of air inside and outside the intermediate ring 30. After the inner cap is completely closed, the sealing effect of the sealing ring is not affected by the exhaust passage.

[0030] When the inner cap 10 is closed, air between the sealing ring 20 and the intermediate ring 30 can be exhausted through the exhaust passage. Similarly, when the inner cap 10 is opened, outside air can enter a region between the intermediate ring 30 and the sealing ring 20 through the exhaust passage, thereby eliminating a difference between internal and external pressures of the region between the sealing ring 20 and the intermediate ring 30, and facilitating smooth opening and closing of the inner cap. In the present disclosure, the inner cap and the intermediate ring are sealed by the sealing ring, so as to seal the powder pan, thereby preventing the cosmetic material stored in the container from being contaminated by outside air for a long time. The exhaust passage facilitates the circulation of the air inside and outside the intermediate ring, so as to open and close the inner cap conveniently, thereby improving the consumer experience. Therefore, while ensuring the sealing effect, the present disclosure has an exhaust function, and is strongly practical.

[0031] A hermetically attached region is provided between the sealing ring 20 and the intermediate ring 30. Optionally, in the hermetically attached region, the sealing ring 20 is in interference fit with the intermediate ring 30. The exhaust passage is located at a side of the hermetically attached region away from the powder pan 40. As shown in FIG. 1, the powder pan 40 is located at a lower side of the hermetically attached region, and the exhaust passage is located at an upper side of the hermetically attached region, thereby ensuring that the hermetic effect between the sealing ring 20 and the intermediate ring 30 is not affected by the exhaust passage.

[0032] As shown in FIG. 1 and FIG. 2, an outer sidewall of the sealing ring 20 extends outward along a radial direction to form annular protrusion 21. An inner sidewall of the intermediate ring 30 is recessed inward to form annular groove 34. The annular protrusion 21 is interference-fitted into the annular groove 34. The annular protrusion 21 and the annular groove 34 are located in the hermetically attached region. With the annular protrusion 21 and the annular groove 34 that are fitted to each other, the sealing effect of the sealing ring 20 can further be improved.

[0033] The exhaust passage includes exhaust grooves 33. N exhaust grooves 33 are formed between the sealing ring 20 and the intermediate ring 30. The N is greater than or equal to 1, the N being an integer. When the N is greater than or equal to 2, distances between every two adjacent ones of the exhaust grooves 33 are the same. That is, when there are two or more exhaust grooves 33, the exhaust grooves 33 are uniformly distributed on the outer sidewall of the sealing ring 20 or the inner sidewall of the intermediate ring 30.

[0034] In a first possible implementation, the exhaust grooves 33 are formed in the outer sidewall of the sealing ring 20. The exhaust grooves 33 are formed along a circumferential direction of the outer sidewall of the sealing ring 20. When the inner cap 10 is closed onto the intermediate ring 30, the exhaust grooves 33 communicate with an outer side of the intermediate ring 30. When the inner cap 10 is completely closed onto the intermediate ring 30, the sealing ring 20 is in interference fit with the intermediate ring 30 for sealing. In the implementation, the exhaust grooves 33 are formed in the outer sidewall of the sealing ring 20. After the inner cap 10 is attached to the intermediate ring 30, the exhaust grooves 33 penetrate through an upper end surface of the intermediate ring 30 for ventilation.

[0035] In a second possible implementation, the exhaust grooves 33 are formed in the inner sidewall of the intermediate ring 30. As shown in FIG. 9 and FIG. 10, in the implementation, the exhaust grooves 33 are formed in the intermediate ring 30. That is, the exhaust grooves 33 are formed along a circumferential direction of the inner sidewall of the intermediate ring 30. The exhaust grooves 33 penetrate through the upper end surface of the intermediate ring 30. By forming the exhaust grooves 33 in the inner sidewall of the intermediate ring 30, the whole product is more aesthetically pleasing.

[0036] As shown in FIG. 10, the exhaust grooves 33 are located above the annular groove 34. When the inner cap 10 is closed onto the intermediate ring 30, the air between the sealing ring 20 and the intermediate ring 30 is exhausted from the intermediate ring through the exhaust grooves 33, such that the inner cap is completely sealed to the intermediate ring. After the inner cap is closed onto the intermediate ring, since the annular groove 34 of the intermediate ring and the annular protrusion 21 of the sealing ring are located below the exhaust grooves 33, the sealing effect of the sealing ring is not affected by the exhaust grooves.

[0037] For any two points that are respectively a point A and a point B in each of the exhaust grooves 33, if a distance from the point A to an upper end surface of the exhaust groove 33 is less than a distance from the point B to the upper end surface of the exhaust groove 33, a width of the exhaust groove 33 corresponding to the point A is greater than or equal to a width of the exhaust groove 33 corresponding to the point B. That is, the exhaust groove 33 is of a tapering-off conical structure from top to bottom or a columnar structure that is the same from top to bottom. As shown in FIG. 9, the exhaust groove 33 is arranged along the circumferential direction of the intermediate ring 30. In the circumferential direction of the intermediate ring 30, the exhaust groove 33 includes a left end surface and a right end surface that are opposite to each other. The so-called width of the exhaust groove 33 refers to a distance from the left end surface to the right end surface.

[0038] As shown in FIG. 7 and FIG. 8, the sealing ring 20 is located on a lower end surface of the inner cap 10. The sealing ring 20 is made of an elastic material. The inner cap 10 and the sealing ring 20 are integrally formed by two-shot molding. Integrally forming the inner cap 10 and the sealing ring 20 through injection molding ensures a high bonding strength and a good sealing effect between the inner cap and the sealing ring. Optionally, the sealing ring is made of the elastic material. Hardness of the sealing ring is less than hardness of the inner cap.

[0039] As shown in FIG. 1 and FIG. 2, the sealing ring 20 includes an annular structure that is open at an upper end and a lower end. The inner sidewall of the sealing ring 20 is attached to the outer sidewall of the inner cap 10. A longitudinal cross-section of the inner sidewall of the sealing ring 20 includes arc-shaped segment 23 and first straight segment 24 that are connected to each other. The arc-shaped segment 23 is located above the first straight segment 24. The so-called longitudinal cross-section of the sealing ring 20 refers to a cross-section passing through an axial centerline of the inner cap 10. The design in which the longitudinal cross-section of the inner sidewall of the sealing ring 20 includes the arc-shaped segment 23 and the first straight segment 24 is intended to accommodate a structure of the outer sidewall of the inner cap 10, so as to ensure the bonding strength and the sealing effect between the sealing ring and the inner cap.

[0040] Optionally, the sealing ring 20 is made of a TPE material. The inner cap 10 and the intermediate ring 30 are made of a polyolefin material. Hardness of the sealing ring 20 is less than hardness of each of the inner cap 10 and the intermediate ring 30.

[0041] As shown in FIG. 2, relief groove 22 is formed in a lower end surface of the sealing ring 20. The relief groove 22 includes an upper end being a sealed end, and a lower end being an open end. The relief groove 22 is a blind groove. The relief groove 22 includes the upper end being the sealed end, and the lower end being the open end. Due to the relief groove 22, when the sealing ring 20 is sealed to the intermediate ring 30, the sealing ring 20 can deform toward the relief groove, such that the inner cap 10 is closed onto the intermediate ring conveniently, reducing the frictional force between the sealing ring 20 and the intermediate ring 30. After the inner cap 10 is attached to the intermediate ring 30, the sealing ring 20 is restored to a normal state to seal the intermediate ring 30.

[0042] As shown in FIG. 9 and FIG. 10, first sleeve 31 and second sleeve 32 are fixedly disposed on the intermediate ring 30. The second sleeve 32 is located outside the first sleeve 31. The exhaust passage is located between the sealing ring 20 and an inner sidewall of the first sleeve 31. The sealing ring 20 is hermetically attached to the inner sidewall of the first sleeve 31. The second sleeve 32 and the inner cap 10 are snap-fitted. Optionally, the exhaust grooves 33 are formed in the inner sidewall of the first sleeve 31. As shown in FIG. 4 and FIG. 5, a gap is formed between the first sleeve 31 and the second sleeve 32. The inner cap 10 is inserted into the gap. The outer sidewall of the inner cap 10 is snap-fitted with an inner sidewall of the second sleeve 32. The outer sidewall of the sealing ring 20 is hermetically attached to the inner sidewall of the first sleeve 31.

[0043] As shown in FIG. 1, FIG. 4 and FIG. 6, the inner cap 10 is rotatably disposed on the intermediate ring 30 through a first hinge assembly. The inner cap 10 and the intermediate ring 30 are snap-fitted. The powder pan 40 and the intermediate ring 30 are snap-fitted. The first hinge assembly includes first hinge 11, second hinge 35, and first hinge shaft 12. As shown in FIG. 8, the first hinge 11 is fixedly disposed on the inner cap 10. As shown in FIG. 9 and FIG. 10, the second hinge 35 is fixedly disposed on the intermediate ring 30. As shown in FIG. 4, in assembly, after the first hinge 11 and the second hinge 35 are docked, the first hinge shaft 12 penetrates into the first hinge 11 and the second hinge 35, so as to rotatably connect the inner cap 10 and the intermediate ring 30. As shown in FIG. 1, the inner cap 10 and the intermediate ring 30 are fixed in a manner such as a snap protrusion and a snap groove, or snap protrusions. The powder pan 40 and the intermediate ring 30 are fixed in a manner such as a snap protrusion and a snap groove, or snap protrusions.

[0044] As shown in FIG. 1 and FIG. 3, the cosmetic container further includes a base assembly and outer cap 50. The cosmetic cartridge is detachably connected to the base assembly. The outer cap 50 is rotatably disposed on the base assembly through a second hinge assembly. The outer cap 50 can be closed onto the inner cap 10.

[0045] As shown in FIG. 1 and FIG. 3, the base assembly includes outer base 70 and inner base 60 fixedly disposed in the outer base 70. The intermediate ring 30 is detachably disposed in the inner base 60. The inner base 60 and the outer base 70 are fixed in a manner such as a snap protrusion and a snap groove, or snap protrusions. The intermediate ring 30 and the inner base 60 are fixed in a manner such as a snap protrusion and a snap groove, or snap protrusions.

[0046] The inner cap 10, the intermediate ring 30, and the powder pan 40 constitute the cartridge. After the material in the powder pan 40 is used up, the cartridge is detached and replaced with a new one for continuous use. Therefore, other components in the cosmetic container can be reused, achieving energy conservation, environmental protection, and cost savings. In assembly, the cartridge is disposed, the material is filled into the powder pan 40, and the filled cartridge is disposed in the base assembly. When the material is filled, in case of a defect due to misoperation, only the powder pan 40 is detached independently, and replaced with a new one.

[0047] A lower surface of the powder pan 40 may be partially exposed or the lower surface of the powder pan 40 may be completely exposed. When the lower surface of the powder pan 40 is partially exposed, the powder pan 40 can be pushed up from a lower end of the container, such that the whole cartridge is separated from the base assembly upward. When the lower surface of the powder pan 40 is completely exposed, the cartridge can be directly pressed from a top of the container, such that the whole cartridge is separated from the base assembly downward. Therefore, the cartridge is detached conveniently.

[0048] As shown in FIG. 1 and FIG. 3, the second hinge assembly includes third hinge 51, fourth hinge 71, and second hinge shaft 52. As shown in FIG. 3, the third hinge 51 is fixedly disposed on the outer cap 50. The fourth hinge 71 is fixedly disposed on the outer base 70. As shown in FIG. 1, in assembly, after the third hinge 51 and the fourth hinge 71 are docked, the second hinge shaft 52 penetrates into the third hinge 51 and the fourth hinge 71, so as to rotatably connect the outer cap 50 and the outer base 70. Optionally, mirror 54 is fixedly attached to an inner side of the outer cap 50. A powder puff configured to dip the cosmetic material is disposed on the inner cap 10.

[0049] In Embodiment 1, the outer cap 50 and the outer base 70 are fixed through a snap-fit assembly. As shown in FIG. 1 and FIG. 3, the snap-fit assembly includes button 72 and groove 53. The button 72 is disposed in the outer base 70. Hook 73 is disposed on the button 72. The groove 53 is formed in an inner sidewall of the outer cap 50. The hook 73 is snap-fitted into the groove 53 to fix the outer cap 50 and the outer base 70. An elastic member is fixedly disposed on the button 72. In use, pressing the button 72 makes the elastic member deform, such that the hook 73 is separated from the groove 53 to open the outer cap 50. After the button is released, the button 72 is restored through the elastic member. Rear fastener 74 is disposed between the outer cap 50 and the outer base 70.

[0050] In Embodiment 2 and Embodiment 3, the outer cap 50 and the outer base 70 are fixed through an attracting assembly.

The second magnet 75 is disposed in the outer base 70. The first magnet 55 and the second magnet 75 attract each other to fix the outer cap 50 and the outer base 70. Mesh fabric 36 is welded on the intermediate ring 30. The mesh fabric 36 is located on the powder pan 40. In the embodiment, the conventional snap-fit assembly is replaced with the first magnet 55 and the second magnet 75, such that the operation is more convenient.

[0052] In Embodiment 3, as shown in FIG. 14, the attracting assembly includes magnetic metal piece 56 and second magnet 75. The second magnet 75 is disposed in one of the outer cap 50 and the outer base 70, while the magnetic metal piece 56 is disposed in the other of the outer cap 50 and the outer base 70. The second magnet 75 and the magnetic metal piece 56 attract each other to fix the outer cap 50 and the outer base 70. The magnetic metal piece 56 is made of a ferromagnetic material. The ferromagnetic material includes iron, cobalt, nickel, and an alloy thereof. In the embodiment, the snap-fit assembly is replaced with the second magnet 75 and the magnetic metal piece 56. In FIG. 14, the magnetic metal piece 56 is disposed in the outer cap 50, and the second magnet 75 is disposed in the outer base 70.
