[0002] For existing cosmetic containers, in order to ensure hermetic storage of the material, an inner cap and an intermediate ring are sealed by a sealing ring. However, when the inner cap is closed onto the intermediate ring, air in the intermediate ring is hardly exhausted due to interference fit between the sealing ring and the intermediate ring, causing difficulty in closing the inner cap. Similarly, the inner cap is difficult to be opened since air cannot easily enter the intermediate ring, causing inconvenience to users.CONTENT OF THE INVENTION

[0003] In order to overcome the above defects, the present disclosure provides a cosmetic cartridge with high sealing performance. According to the cosmetic cartridge with high sealing performance, an exhaust passage is formed between the sealing ring and the intermediate ring, such that air can be exhausted from the intermediate ring through the exhaust passage or can enter the intermediate ring through the exhaust passage, thereby facilitating smooth opening and closing of the inner cap to improve consumer experience.

[0007] Optionally, the exhaust grooves are formed along a circumferential direction of the outer sidewall of the sealing ring; when the inner cap is closed onto the intermediate ring, the exhaust grooves communicate with an outer side of the intermediate ring; and when the inner cap is completely closed onto the intermediate ring, the sealing ring is in interference fit with the intermediate ring for sealing.

[0008] Optionally, the exhaust grooves are formed along a circumferential direction of the inner sidewall of the intermediate ring; and the exhaust grooves penetrate through an outer side of the intermediate ring.

[0009] Optionally, an upper end of each of the exhaust grooves penetrates through an upper surface of the intermediate ring; an inner side of the exhaust groove penetrates through the inner sidewall of the intermediate ring; a lower end surface of the exhaust groove includes an oblique surface or an arc-shaped surface; and the lower end surface of the exhaust groove extends from the inner side of the exhaust groove to the inner sidewall of the intermediate ring.

[0010] Optionally, the outer sidewall of the sealing ring extends outward along a radial direction to form an annular protrusion; the inner sidewall of the intermediate ring is recessed inward to form an annular groove; the annular protrusion is interference-fitted into the annular groove; the annular protrusion and the annular groove form the hermetically attached region; and the exhaust groove is located above the annular groove.

[0011] Optionally, the annular protrusion has a width of L1; the exhaust groove has a depth of L2; the L1 is greater than the L2; and an upper end of the annular protrusion abuts against a lower end of the exhaust groove.

[0012] Optionally, for any two points that are respectively a point A and a point B in the exhaust groove; if a distance from the point A to an upper end surface of the exhaust groove is less than a distance from the point B to the upper end surface of the exhaust groove, a width of the exhaust groove corresponding to the point A is greater than or equal to a width of the exhaust groove corresponding to the point B.

[0013] Optionally, the exhaust grooves penetrate through the inner sidewall and an outer sidewall of the intermediate ring.

[0014] Optionally, a first sleeve and a second sleeve are fixedly disposed on the intermediate ring; the second sleeve is located outside the first sleeve; a stepped surface is disposed between the first sleeve and the second sleeve; the exhaust passage is located between the sealing ring and an inner sidewall of the first sleeve; the sealing ring is hermetically attached to the inner sidewall of the first sleeve; the connecting ring abuts against the stepped surface; and the second sleeve and the connecting ring are snap-fitted through a snap protrusion and a snap groove.

[0016] The present disclosure has the following beneficial effects: 1) In the present disclosure, the exhaust passage is formed between the sealing ring and the intermediate ring. The exhaust passage is configured to realize circulation of air inside and outside the intermediate ring. When the inner cap is closed, air between the sealing ring and the intermediate ring can be exhausted timely through the exhaust passage. When the inner cap is opened, outside air enters a region between the intermediate ring and the sealing ring through the exhaust passage, thereby eliminating a difference between internal and external pressures of the region between the sealing ring and the intermediate ring, 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. 2) In the present disclosure, the exhaust passage is located above the annular groove. When the inner cap is closed onto the intermediate ring, the air between the sealing ring and the intermediate ring is exhausted from the intermediate ring through the exhaust passage, such that the inner cap is completely sealed to the intermediate ring. After the inner cap is closed onto the intermediate ring, the intermediate ring is sealed through the interference fit between the annular groove and the annular protrusion. Since the annular groove of the intermediate ring and the annular protrusion of the sealing ring are located below the exhaust passage, the sealing effect of the sealing ring is not affected by the exhaust passage. The present disclosure overcomes the technical problem that the exhaust and sealing are hardly balanced. DESCRIPTION OF THE DRAWINGS

SPECIFIC IMPLEMENTATIONS

[0019] 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.

[0020] 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.

[0021] 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.

[0022] Embodiment 1: As shown in FIGS. 1-19, a cosmetic container includes a cosmetic cartridge with high sealing performance. The cosmetic cartridge with high sealing performance 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 and connecting ring 13 are fixedly disposed on the inner cap 10. The inner cap 10 is rotatably connected to the intermediate ring 30. When the inner cap 10 is closed onto the intermediate ring 30, the connecting ring 13 is snap-fitted with the intermediate ring 30, and the sealing ring 20 can 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.

[0023] 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. That is, 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. The exhaust passage is configured to realize circulation of air inside and outside the intermediate ring 30. The sealing effect of the sealing ring is not affected by the exhaust passage.

[0024] 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.

[0025] 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.

[0026] The exhaust passage includes exhaust grooves 33. N exhaust grooves 33 are formed between the sealing ring 20 and the intermediate ring 30. 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 an outer sidewall of the sealing ring 20 or an inner sidewall of the intermediate ring 30.

[0027] In a 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.

[0028] In another possible implementation, the exhaust grooves 33 are formed in the inner sidewall of the intermediate ring 30. As shown in FIG. 13, 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 an outer side 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.

[0029] An upper end of each of the exhaust grooves 33 penetrates through an upper surface of the intermediate ring 30. An inner side of the exhaust groove 33 penetrates through the inner sidewall of the intermediate ring 30. A lower end surface of the exhaust groove 33 includes an oblique surface or an arc-shaped surface. The lower end surface of the exhaust groove 33 extends from the inner side of the exhaust groove 33 to the inner sidewall of the intermediate ring 30. That is, as shown in FIG. 12, the exhaust groove 33 is arranged along a vertical direction. The upper end of the exhaust groove 33 penetrates through the upper surface of the intermediate ring.

[0030] As shown in FIG. 1 and FIG. 2, the outer sidewall of the sealing ring 20 extends outward along a radial direction to form annular protrusion 21. The 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 form the hermetically attached region. The exhaust groove 33 is located above the annular groove 34. That is, the exhaust groove 33 is located at a side of the annular groove 34 away from the powder pan 40. 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 be further improved. As shown in FIG. 13, the exhaust groove 33 is located above the annular groove 34. When the inner cap 10 is closed onto the intermediate ring 30, air between the sealing ring 20 and the intermediate ring 30 is exhausted from the intermediate ring through the exhaust groove 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 groove 33, the sealing effect of the sealing ring is not affected by the exhaust groove.

[0031] As shown in FIG. 7, the annular protrusion 21 has a width of L1. The exhaust groove 33 has a depth of L2. The L1 is greater than the L2. An upper end of the annular protrusion 21 abuts against a lower end of the exhaust groove 33, so as to block the lower end of the exhaust groove 33 through the annular protrusion 21.

[0032] For any two points that are respectively point A and point B in the exhaust groove 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. 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.

[0033] As shown in FIGS. 12-14, in a first possible implementation, the width of the exhaust groove 33 corresponding to the point A is the same as the width of the exhaust groove 33 corresponding to the point B. That is, the exhaust groove 33 is of a columnar structure that is the same from top to bottom.

[0034] As shown in FIGS. 15-17, in a second possible implementation, the width of the exhaust groove 33 corresponding to the point A is greater than the 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.

[0035] In a third possible implementation, the exhaust groove 33 penetrates through the inner sidewall and an outer sidewall of the intermediate ring 30. That is, the exhaust groove 33 is formed along a horizontal direction, and the exhaust groove 33 penetrates through an entire thickness direction of the intermediate ring 30. Through the exhaust groove 33, gas on the inner sidewall of the intermediate ring 30 is introduced to the outer sidewall, or gas on the outer sidewall is introduced to the inner sidewall. This also achieves the gas exhausting or entering function.

[0036] As shown in FIGS. 12-17, 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. Stepped surface 37 is disposed between the first sleeve 31 and the second sleeve 32. 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 connecting ring 13 abuts against the stepped surface 37. As shown in FIG. 4, the second sleeve 32 and the connecting ring 13 are snap-fitted through snap protrusion 14 and snap groove 38.

[0037] Optionally, as shown in FIG. 12, the exhaust grooves 33 are formed in the inner sidewall of the first sleeve 31. As shown in FIG. 4, the stepped surface 37 is disposed between the first sleeve 31 and the second sleeve 32. A lower end of the connecting ring 13 abuts against the stepped surface 37, so as to limit the inner cap 10 through the stepped surface 37. The outer sidewall of the sealing ring 20 is hermetically attached to the inner sidewall of the first sleeve 31. As shown in FIG. 4, in a possible implementation, an inner side of the second sleeve 32 is provided with the snap groove 38. An outer sidewall of the connecting ring 13 is provided with the snap protrusion 14. The snap protrusion 14 is snap-fitted into the snap groove 38 to fix the inner cap 10 and the intermediate ring 30. In another possible implementation, an inner side of the second sleeve 32 is provided with the snap protrusion 14. An outer sidewall of the connecting ring 13 is provided with the snap groove 38. The snap protrusion 14 is snap-fitted into the snap groove 38 to fix the inner cap 10 and the intermediate ring 30.

[0038] As shown in FIG. 1, FIG. 3 and FIG. 5, the inner cap 10 is rotatably disposed on the intermediate ring 30 through a first hinge assembly. The powder pan 40 is snap-fitted with the intermediate ring 30. The first hinge assembly includes first hinge 11, second hinge 35, and first hinge shaft 12. As shown in FIG. 10, the first hinge 11 is fixedly disposed on the inner cap 10. As shown in FIG. 12 and FIG. 13, the second hinge 35 is fixedly disposed on the intermediate ring 30. As shown in FIG. 6, 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 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.

[0039] As shown in FIG. 1 and FIG. 5, 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.

[0040] 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.

[0041] 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 by 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 assembly is disposed, the material is filled into the powder pan 40, and the filled cartridge assembly 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 by a new one.

[0042] 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 assembly is separated from the base assembly upward. When the lower surface of the powder pan 40 is completely exposed, the cartridge assembly can be directly pressed from a top of the container, such that the whole cartridge assembly is separated from the base assembly downward. Therefore, the cartridge assembly is detached conveniently.

[0043] As shown in FIG. 1 and FIG. 5, the second hinge assembly includes third hinge 51, fourth hinge 71, and second hinge shaft 52. As shown in FIG. 5, the third hinge 51 is fixedly disposed on the outer cap 50. The fourth hinge 71 is fixedly disposed on 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.

[0044] 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. 5, 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, so as 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.

[0045] In Embodiment 2 and Embodiment 3, the outer cap 50 and the outer base 70 are fixed through an attracting assembly.

[0046] In Embodiment 2, as shown in FIG. 20, the attracting assembly includes first magnet 55 and second magnet 75. The first magnet 55 is disposed in the outer cap 50. 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.

[0047] In Embodiment 3, as shown in FIG. 21, 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, etc. In the embodiment, the snap-fit assembly is replaced with the second magnet 75 and the magnetic metal piece 56. In FIG. 13, the magnetic metal piece 56 is disposed in the outer cap 50, and the second magnet 75 is disposed in the outer base 70. Certainly, the second magnet 75 may also be disposed in the outer cap 50, and the magnetic metal piece 56 may also be disposed in the outer base 70.

[0048] In the present disclosure, the outer cap 50 and the outer base 70 are fixed through the snap-fit assembly or fixed through the attracting assembly. Therefore, the outer cap 50 and the outer base 70 are connected simply and reliably, with low cost and convenience in use.

[0049] It should be noted that those of ordinary skill in the art can further make variations and improvements without departing from the conception of the present disclosure. These variations and improvements all fall within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the appended claims.
