[0049] 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.

[0050] 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.

[0051] 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.

[0052] Example 1: Figure 1-19As shown, a cosmetic container includes a highly sealed cosmetic liner, the liner includes an inner cover 10, a middle ring 30 and a powder tray 40, the powder tray 40 is fixedly installed in the middle ring 30, the inner cover 10 is fixedly provided with a sealing ring 20 and a connecting ring 13, the inner cover 10 is rotatably connected to the middle ring 30, when the inner cover 10 is covered on the middle ring 30, the connecting ring 13 is engaged and fixed with the middle ring 30, the sealing ring 20 can seal the middle ring 30 to achieve the airtight function of the powder tray 40, wherein the powder tray 40 stores cosmetic materials.

[0053] 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. That is, a part of the sealing ring 20 is in airtight contact with 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, and the exhaust channel is used for the circulation of gas inside and outside the middle ring 30, and the exhaust channel will not affect the sealing effect of the sealing ring.

[0054] 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.

[0055] 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.

[0056] 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, N is an integer; and when N≥2, the distance between two adjacent exhaust grooves 33 is equal. That is, when two or more exhaust grooves 33 are provided, the exhaust grooves 33 are evenly distributed on the outer wall of the sealing ring 20 or the inner wall of the middle ring 30.

[0057] In a possible implementation, the exhaust groove 33 is provided on the outer side wall of the sealing ring 20. The exhaust groove 33 is provided on the outer side wall of the sealing ring 20 along the circumferential direction. When the inner cover 10 covers the middle ring 30, the exhaust groove 33 is communicated with the outer side of the middle ring 30. When the inner cover 10 completely covers the middle ring 30, the sealing ring 20 and the middle ring 30 are interference fit to achieve sealing. In this implementation, the exhaust groove 33 is provided on the outer side wall of the sealing ring 20. When the inner cover 10 is combined with the middle ring 30, the exhaust groove 33 passes through the upper end surface of the middle ring 30 to achieve the purpose of ventilation.

[0058] In another possible implementation, the exhaust groove 33 is provided on the inner side wall of the middle ring 30. Fig.13 As shown, in this embodiment, the exhaust groove 33 is provided on the middle ring 30, that is, the inner side 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 outer side of the middle ring 30. The exhaust groove 33 is provided on the inner side wall of the middle ring 30, which improves the overall aesthetics of the product.

[0059] The upper end of the exhaust groove 33 is connected to the upper surface of the middle ring 30, the inner side of the exhaust groove 33 is connected to the inner wall of the middle ring 30, the lower end surface of the exhaust groove 33 includes an inclined surface or an arc surface, and the lower end surface of the exhaust groove 33 extends from the inner side of the exhaust groove 33 to the inner wall of the middle ring 30. Fig.12 As shown, the exhaust grooves 33 are arranged in the vertical direction, and the upper ends of the exhaust grooves 33 pass through the upper surface of the middle ring.

[0060] 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 fitted in the annular groove 34 with interference fit, and the annular protrusion 21 and the annular groove 34 form an airtight fitting area, and the exhaust groove 33 is located above the annular groove 34. That is, the exhaust groove 33 is located on the side of the annular groove 34 away from the powder tray 40. The use of the mutually matched annular protrusion 21 and the annular groove 34 can further improve the sealing effect of the sealing ring 20. Fig.13As 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.

[0061] like Figure 7 As shown, the width of the annular protrusion 21 is L1, the depth of the exhaust groove 33 is L2, L1 is greater than L2, and the upper end of the annular protrusion 21 abuts against the lower end of the exhaust groove 33 to block the lower end of the exhaust groove 33 through the annular protrusion 21.

[0062] Take any two points in the exhaust groove 33, namely point A and point B. If the distance between point A and the upper end surface of the exhaust groove 33 is less than the distance between point B and the upper end surface of the exhaust groove 33, the width of the exhaust groove 33 corresponding to point A is greater than or equal to the width of the exhaust groove 33 corresponding to point B. The exhaust groove 33 is arranged along the circumference of the middle ring 30. In the circumferential direction of the middle ring 30, the exhaust groove 33 includes a left end surface and a right end surface arranged oppositely. The width of the exhaust groove 33 refers to the distance between the left end surface and the right end surface.

[0063] like Figure 12-14 As shown, in a first possible implementation manner, the width of the exhaust groove 33 corresponding to point A is equal to the width of the exhaust groove 33 corresponding to point B, that is, the exhaust groove 33 is a columnar structure with equal upper and lower portions.

[0064] like Figure 15-17 As shown, in the second possible implementation manner, the width of the exhaust groove 33 corresponding to point A is greater than the width of the exhaust groove 33 corresponding to point B, that is, the exhaust groove 33 has a cone-shaped structure that is larger at the top and smaller at the bottom.

[0065] In a third possible implementation, the exhaust groove 33 passes through the inner wall and the outer wall of the middle ring 30. That is, the exhaust groove 33 is opened in the horizontal direction, and the exhaust groove 33 is arranged throughout the thickness direction of the middle ring 30. The gas on the inner wall of the middle ring 30 is introduced into the outer wall through the exhaust groove 33; or the gas on the outer wall is introduced into the inner wall, which also achieves the function of exhausting or inletting.

[0066] like Figure 12-17 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, and a step surface 37 is provided between the first cylinder 31 and the second cylinder 32. The exhaust channel is located between the sealing ring 20 and the inner side wall of the first cylinder 31, the sealing ring 20 is airtightly attached to the inner side wall of the first cylinder 31, and the connecting ring 13 is against the step surface 37. Figure 4As shown, the second cylinder 32 and the connecting ring 13 are fixed by the clamping point 14 and the clamping groove 38 .

[0067] Alternatively, if Fig.12 As shown, the exhaust groove 33 is opened on the inner wall of the first cylinder 31. Figure 4 As shown, there is a step surface 37 between the first cylinder 31 and the second cylinder 32, and the lower end of the connecting ring 13 abuts against the step surface 37 to limit the inner cover 10 through the step surface 37, and the outer wall of the sealing ring 20 is airtightly attached to the inner wall of the first cylinder 31. Figure 4 As shown, in one possible embodiment, a card slot 38 is provided on the inner side of the second cylinder 32, and a card point 14 is provided on the outer side wall of the connecting ring 13, and the card point 14 is inserted into the card slot 38 to fix the inner cover 10 and the middle ring 30; in another possible embodiment, a card point 14 is provided on the inner side of the second cylinder 32, and a card slot 38 is provided on the outer side wall of the connecting ring 13, and the card point 14 is inserted into the card slot 38 to fix the inner cover 10 and the middle ring 30.
