[0056] The outer surface of the middle beam 430 structure is provided with a groove, and a rubber ring is placed in the groove, so as to further increase the air tightness of the lipstick container 100 and avoid the volatilization of the lipstick paste.

[0057] The inner surface of the material cup 420 is provided with a boss extending in the horizontal direction, which is used to carry the lipstick paste.

[0058] Embodiment 2

[0059] The structure of the present embodiment is basically the same as that of embodiment 1, and the same structure will not be described in detail. The difference lies in that:

[0060] As shown in Figure 3 and Figure 4 Compared with embodiment 1, the pitch of the internal thread groove 411 of the rotating structure 410 in the present embodiment is smaller, and the screw thread 421 on the material cup 420 is also correspondingly reduced, so that the slow rotation effect of the lipstick container 100 is better, and the lipstick paste is rotated out more slowly when the lipstick container 100 is used, avoiding the breakage of the paste due to too fast rotation.

[0061] Embodiment 3

[0062] The structure of the present embodiment is basically the same as that of embodiment 2, and the same structure will not be described in detail. The difference lies in that:

[0063] As shown in Figures 5-7As shown, in this embodiment, the inner surface of the middle bundle 430 is provided with anti-slip teeth 810, and the outer surface of the material cup 420 is provided with anti-slip grooves 820 in the movement path of the anti-slip teeth 810. The anti-slip teeth 810 and the anti-slip grooves 820 match in shape. By providing the anti-slip grooves 820 and the anti-slip teeth 810, the lipstick container 100 has a one-way rotation effect. The inner surface of the middle bundle 430 is provided with anti-slip teeth 810, and the outer surface of the material cup 420 is provided with anti-slip grooves 820 in the movement path of the anti-slip teeth 810. The anti-slip teeth 810 and the anti-slip grooves 820 match in shape. When the material cup 420 is rotated out, the anti-slip teeth 810 engage with the anti-slip grooves 820, thereby preventing the lipstick paste from rotating back and only rotating out in one direction.

[0064] Example 4

[0065] The structure of this embodiment is basically the same as that of embodiment 1, and the same structure will not be repeated here. The difference lies in:

[0066] like Figure 8 As shown, in this embodiment, the base 300 also includes an application portion 340, which can be used to apply lipstick. The application portion 340 is located at one end of the base 300 near the through hole 210, so that the application portion 340 at least partially extends into the interior of the housing 200. By providing the application portion 340 on the lipstick container 100, the user does not need to use their fingers to apply lipstick, nor does they need to carry an additional application tool, making it more convenient to carry. The application of the lipstick by the application portion 340 also improves the makeup effect of the lipstick. The application portion 340 at least partially extends into the interior of the housing 200, thereby preventing external contaminants from contaminating the application portion 340 and further facilitating the cleaning of the application portion 340.

[0067] In this embodiment, the application portion 340 is arranged on the second part 320 so that the application portion 340 can be fully inserted into the interior of the shell 200 and abut against the surface of the shell 200 through the upper surface of the first part 310, thereby better sealing the application portion 340 and preventing external pollutants from contaminating the application portion 340.

[0068] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate the orientation or position relationship of the device or component during normal use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation at any time. Therefore, they should not be understood as limiting the present invention in this regard.

[0069] Although the specific embodiments of the present application are described above, those skilled in the art should understand that this is only an example, the protection scope of the present application is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present application, but these changes and modifications all fall within the present application.
