[0047] 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.

[0048] 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.

[0049] 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.

[0050] Example 1: Figure 1-13As shown, a cosmetic container includes a 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, and a sealing ring 20 is fixedly provided on the inner cover 10. The sealing ring 20 and the middle ring 30 are interference-fitted so that the sealing ring 20 can seal the middle ring 30. 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, and when the inner cover 10 is opened, the exhaust channel is used for 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 portion of the sealing ring 20 is in airtight fit with the middle ring 30, thereby sealing the powder tray 40 below the middle ring 30 and preventing external air from entering the powder tray 40; an exhaust channel is formed between another portion of the sealing ring 20 and the middle ring 30, and during the process of closing and opening the inner cover 10, 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.

[0051] 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.

[0052] 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.

[0053] like Figure 1 and Figure 2As 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.

[0054] The exhaust channel includes an exhaust groove 33. N exhaust grooves 33 are provided between the sealing ring 20 and the middle ring 30, wherein N≥1 and N is an integer. 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.

[0055] In a first 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 is covered on the middle ring 30, the exhaust groove 33 is communicated with the outer side of the middle ring 30. When the inner cover 10 is completely covered on the middle ring 30, the sealing ring 20 and the middle ring 30 are sealed by interference fit. 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.

[0056] In a second possible implementation, the exhaust groove 33 is opened on the inner side wall of the middle ring 30, such as Fig. 9 and Fig.10 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 upper end surface 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.

[0057] like Fig.10 As 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.

[0058] 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 smaller than the distance between point B and the upper end surface of the exhaust groove 33, then 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. That is, the exhaust groove 33 is a cone-shaped structure with a larger upper part and a smaller lower part, or a columnar structure with equal upper and lower parts. Fig. 9As shown, 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 face and a right end face that are arranged oppositely. The width of the exhaust groove 33 refers to the distance between the left end face and the right end face.

[0059] like Figure 7 and Figure 8 As shown, the sealing ring 20 is located at the lower end surface of the inner cover 10, and the sealing ring 20 is made of elastic material. 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. Optionally, the sealing ring is made of elastic material, and the hardness of the sealing ring is less than the hardness of the inner cover.

[0060] like Figure 1 and Figure 2 As shown, the sealing ring 20 comprises an annular structure with upper and lower ends opened, the inner side wall of the sealing ring 20 is combined with the outer side wall of the inner cover 10, and the longitudinal section of the inner side wall of the sealing ring 20 comprises an arc segment 23 and a straight line segment 24 connected to each other, and the arc segment 23 is located above the straight line segment 24. The so-called longitudinal section of the sealing ring 20 refers to the section passing through the axial center line of the inner cover 10, and the longitudinal section of the inner side wall of the sealing ring 20 comprises the arc segment 23 and the straight line segment 24 in order to adapt to the structure of the outer side wall of the inner cover 10, so as to ensure the bonding strength and sealing effect between the sealing ring and the inner cover.

[0061] 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 .

[0062] like Figure 2 As shown, the lower end surface of the sealing ring 20 is provided with an escape groove 22, the upper end of the escape groove 22 is a closed end, and the lower end is an open end. The escape groove 22 is a blind groove, the upper end of the escape groove 22 is a closed end, and the lower end is an open end. Due to the existence of the escape groove 22, when the sealing ring 20 is sealed on the middle ring 30, the sealing ring 20 can be deformed toward the escape groove direction, so that the inner cover 10 is convenient to cover the middle ring, reducing the friction between the sealing ring 20 and the middle ring 30. When the inner cover 10 is combined with the middle ring 30, the sealing ring 20 returns to normal to seal the middle ring 30.

[0063] like Fig. 9 and Fig.10 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. Figure 4 and Figure 5 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.

[0064] like Figure 1 , Figure 4 and Figure 6 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.

Fig. 9 and Fig.10 As shown, the second hinge 35 is fixedly mounted on the middle ring 30. Figure 4 As 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 a card point and a card slot, a card point and a card point, etc., and the powder tray 40 and the middle ring 30 are fixed by means of a card point and a card slot, a card point and a card point, etc.

[0065] like Figure 1 and Figure 3 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 .

[0067] 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.

[0068] 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.
