[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0030] 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 do not necessarily need to describe a specific order or sequence. It should be understood that such objects can be interchanged under appropriate circumstances 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 "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0031] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial positional relationship of a device or feature shown in the figure with other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figure for the device. For example, if the device in the drawing is inverted, the device described as "above or over other devices or structures" will then be positioned "below or under other devices or structures". Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0032] Embodiment 1: As Figure 1-8 shown, an inner container assembly includes an inner cover 100 and an inner tray 300. A rotating shaft 110 is fixedly provided on the inner cover 100, and a snap ring 311 is fixedly provided on the inner tray 300. The snap ring 311 is sleeved on the rotating shaft 110 to rotatably connect the inner cover 100 to the inner tray 300, and the inner cover 100 covers the inner tray 300. The inner cover 100 and the inner tray 300 are hermetically bonded through a soft rubber pad 130. The soft rubber pad 130 is provided on a circumferential edge at the bottom of the inner cover 100, and the hardness of the soft rubber pad 130 is less than the hardness of the inner cover 100 and the inner tray 300. The inner cover 100 and the inner tray 300 are sealed through the soft rubber pad 130, so that the inner tray 300 achieves an airtight effect for storing cosmetics that need to be sealed, such as cushion compacts and some cream-based and powder-based cosmetics that are prone to oxidation. At least two ribs 111 radially protrude outward on the outer surface of the rotating shaft 110. The ribs 111 are in interference fit with the snap ring 311, and at least two of the ribs 111 are at different height positions of the rotating shaft 110.

[0033] As Figure 4 shown, the axial direction of the rotating shaft 110 is defined as the height direction of the rotating shaft 110, and the height of the rotating shaft 110 in the figure is H. Among them, "at least two ribs 111 are at different height positions of the rotating shaft 110" means that at least part of at least two ribs 111 is at different height positions of the rotating shaft 110, that is, there are the following two situations. The first situation is that at least two different ribs 111 are completely at different height positions of the rotating shaft 110. In this case, the spaces passed by at least two different ribs 111 after rotating one circle in the circumferential direction do not overlap at all. The second situation is that part of at least two different ribs 111 is at different height positions of the rotating shaft 110 and the remaining part is at the same height position of the rotating shaft 110. In this case, the spaces passed by at least two different ribs 111 after rotating one circle in the circumferential direction do not completely overlap.

[0034] In this application, the interference fit between the convex rib 111 on the rotating shaft 110 and the snap ring 311 on the inner disc 300 is utilized to achieve the function of hovering at any position when the inner cover 100 is opened. Thus, it solves the technical problem that when the interference fit between the entire outer surface of the rotating shaft 110 and the snap ring 311 on the inner disc 300 is used to achieve the hovering function in the prior art, there is a large frictional force between the inner cover 100 and the inner disc 300, making it difficult to open the inner cover 100. Therefore, in this application, the interference fit between the convex rib 111 and the snap ring 311 not only realizes the function of hovering at any position when the inner cover 100 is opened, but also reduces the frictional force between the inner cover 100 and the inner disc 300, reduces the sense of jerk, facilitates the opening and closing of the inner cover 100, and has very strong practicability.

[0035] As Figure 1 shown, the inner container assembly further includes an inner ring 200. The inner ring 200 is installed on the inner disc 300. The inner ring 200 has a cylindrical structure with openings at both the upper and lower ends and a hollow interior. The inner disc 300 has a cylindrical structure with an opening at the upper end, a closed lower end, and a hollow interior. The inner disc 300 is used to store cosmetic materials such as air cushions, creams, and powder compacts. As Figures 3-4 shown, the rotating shaft 110 is fixedly installed on the inner cover 100 through a support block 120. As Figure 8 shown, the inner disc 300 includes an outer ring 310, a middle ring 320, and an inner ring 330. The outer ring 310 is located outside the inner ring 330. The middle ring 320 is located between the outer ring 310 and the inner ring 330. The snap ring 311 is fixedly provided on the outer side wall of the outer ring 310. The inner ring 200 is fixedly installed on the middle ring 320. As Figure 1 shown, the longitudinal cross-section of the snap ring 311 is C-shaped. The snap ring 311 is sleeved on the rotating shaft 110, and the inner side wall of the snap ring 311 is in interference fit with the convex rib 111 to achieve hovering at any position of the inner cover 100, facilitate the opening of the inner container assembly, and facilitate the user to dip the materials.

[0036] As Figure 1 and Figure 8 shown, the inner disc 300 is provided with an outer ring 310, a middle ring 320, and an inner ring 330. The inner ring 330 is used to store cosmetic materials. The outer ring 310 is rotatably installed on the inner cover 100 through the snap ring 311. The inner ring 200 is fixedly installed on the middle ring 320 by interference fit or clamping. A mesh cloth can be fixedly arranged on the inner ring 200. The mesh cloth covers the inner ring 330. When the inner cover 100 is closed, the bottom of the inner cover 100 is hermetically combined with the outer ring 310 through a soft rubber pad 130 and covers the inner ring 330 to seal the materials in the inner ring 330.

[0037] Optionally, different ribs 111 are at different height positions of the rotating shaft 110. That is, at least part of the regions between different ribs 111 are at different height positions of the rotating shaft 110, and the spaces passed by different ribs 111 after rotating one circle in the circumferential direction do not completely coincide or do not completely overlap.

[0038] There are the following two cases. In the first case, different ribs 111 are completely at different height positions of the rotating shaft 110. In this case, the spaces passed by different ribs 111 after rotating one circle in the circumferential direction do not completely coincide; in the second case, part of the regions of different ribs 111 are at different height positions of the rotating shaft 110, and the remaining part of the regions are at the same height position of the rotating shaft 110. In this case, the spaces passed by different ribs 111 after rotating one circle in the circumferential direction do not completely overlap. Optionally, different ribs 111 are completely at different height positions of the rotating shaft 110.

[0039] Optionally, the orthographic projections of at least two ribs 111 on the first plane are at different positions. The first plane is the plane where the bottom surface of the rotating shaft 110 is located. As Figure 4 shown, the bottom surface of the rotating shaft 110 refers to the connection between the lower end of the rotating shaft 110 and the inner cover 100. "The orthographic projections of at least two ribs 111 on the first plane are at different positions" means that at least part of the regions of at least two ribs 111 are at different positions in the orthographic projection on the first plane. That is, there are the following two cases. In the first case, the orthographic projections of at least two different ribs 111 on the first plane do not completely overlap; in the second case, the orthographic projections of at least two different ribs 111 on the first plane partially do not overlap and partially overlap.

[0040] The orthographic projections of different ribs 111 on the first plane are at different positions. That is, there are the following two cases. In the first case, the orthographic projections of two different ribs 111 on the first plane do not completely overlap; in the second case, the orthographic projections of two different ribs 111 on the first plane partially do not overlap and partially overlap.

[0041] As Figure 2 and Figure 3 shown, the shape of the rotating shaft 110 includes a cylindrical structure, and the shape of the rib 111 includes a strip structure. The cylindrical rotating shaft 110 facilitates the rotation of the inner cover 100. The rib 111 being in a strip structure means that the length of the rib 111 is much greater than the width of the rib 111.

[0042] Optionally, the length direction of the rib 111 is along the axial direction of the rotating shaft 110 and / or along the circumferential direction of the rotating shaft 110. That is, there are the following three cases for the arrangement of the rib 111: the length directions of all the ribs 111 are along the axial direction of the rotating shaft 110; or the length directions of all the ribs 111 are along the circumferential direction of the rotating shaft 110; or the length directions of some of the ribs 111 are along the axial direction of the rotating shaft 110, and the length directions of the remaining ribs 111 are along the circumferential direction of the rotating shaft 110.

[0043] As Figure 4 shown, the length of the rib 111 is L, the height of the rotating shaft 110 is H, and the circumference of the rotating shaft 110 is C. In Embodiment 1, as Figure 4 and Figure 6 shown, when the length direction of the rib 111 is along the axial direction of the rotating shaft 110, L is 0.2 times to 0.5 times of H; in this embodiment, the height of the rotating shaft 110 is about three times the length of the rib 111; as Figures 3-6 shown, the length directions of all the ribs 111 are along the axial direction of the rotating shaft 110; in this embodiment, there are three ribs 111 provided on the rotating shaft 110, and the three ribs 111 are located at different height positions of the rotating shaft 110, and the orthographic projections of the three ribs 111 on the first plane are at different positions.

[0044] In Embodiment 2, as Figure 10 and Figure 12 shown, when the length direction of the rib 111 is along the circumferential direction of the rotating shaft 110, L is 0.2 times to 0.5 times of C. In this embodiment, the circumference of the rotating shaft 110 is about three times the length of the rib 111. As Figures 9-12 shown, the lengths of all the ribs 111 are arranged along the circumferential direction of the rotating shaft 110. In this embodiment, there are also three ribs 111 provided on the rotating shaft 110, and the three ribs 111 are located at different height positions of the rotating shaft 110, and the orthographic projections of the three ribs 111 on the first plane are at different positions.

[0045] Optionally, there are 2 - 6 ribs 111 provided on the rotating shaft 110. As Figure 4 , Figure 6 and Figure 12 shown, both Embodiment 1 and Embodiment 2 show three ribs 111. In Embodiment 1, the sum of the lengths of the three ribs 111 is equal to the height of the rotating shaft 110, and in Embodiment 2, the sum of the lengths of the three ribs 111 is equal to the circumference of the rotating shaft 110, which can improve the stability when the inner cover 100 rotates. Of course, 2, 4, 5, or 6 ribs 111 can also be provided on the rotating shaft 110.

[0046] It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several modifications and improvements can still be made, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application shall be subject to the appended claims.
