[0022] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0024] Reference Figures 1 to 2As shown, a cosmetic packaging tube includes a tube body 1 and a cap 2. The tube body 1 is used to hold cosmetics, and the cap 2 is detachably connected to the tube body 1. An application brush 3 is fixed to one end of the tube body 1 away from the cap 2. In actual use, the application brush 3 of the tube body 1 can act as a cosmetic scraper to apply cosmetics, eliminating the need to carry an additional cosmetic scraper, which is very convenient.

[0025] Preferably, the brush 3 and the tube body 1 are an integral structure, which is simple to manufacture and has a low cost. The brush 3 and the tube body 1 are firmly connected and will not be damaged by the brushing action.

[0026] In this embodiment, the tube body 1 has an opening at one end near the cap body 2, and the opening is covered with a sealing film 4. The tube body 1 is provided with a first annular protrusion 11, which is arranged around the opening and surrounds a chamber 12 for containing the auxiliary agent.

[0027] The cover 2 has a recess 21, a top post 22 is provided in the recess 21, and a second annular protrusion 23 is provided around the top post 22 in the recess 21. The second annular protrusion 23 is sleeved on the first annular protrusion 11 and threadedly connected to the first annular protrusion 11. The cover 2 is rotated to adjust the insertion depth of the top post 22 in the chamber 12.

[0028] The cosmetic is loaded into the tube 1 and then sealed with the sealing membrane 4. The chamber 12 can hold the auxiliary agent. The cap 2 is threaded to the tube 1 through the second annular protrusion 23. The second annular protrusion 23 cooperates with the first annular protrusion 11 to seal the chamber 12. In this way, the cosmetic and the auxiliary agent can be packaged separately in the tube. The cap 2 is provided with a top post 22. When it is needed, the position of the top post 22 can be adjusted by rotating the cap 2. When the top post 22 punctures the sealing membrane 4, the auxiliary agent will be added to the cosmetic.

[0029] In the above embodiment, the top column 22 is a hollow column with an opening at one end near the sealing membrane 4. The opening allows the auxiliary agent to enter the interior of the hollow column. The top column 22 is partially located in the chamber 12, and the auxiliary agent can enter the interior of the hollow column. This reduces the space occupied by the top column 22 in the chamber 12 and increases the capacity of the auxiliary agent.

[0030] Preferably, the outer diameter of the hollow column is adapted to the inner diameter of the first annular protrusion 23. The hollow column and the first annular protrusion 11 work together to improve the sealing performance and prevent the auxiliary agent from leaking. The auxiliary agent is basically stored inside the hollow column, and when the hollow column punctures the sealing film, it can maximize the gap in the sealing film.

[0031] In some other embodiments, the top post 22 may also be a solid post, the outer diameter of which is smaller than the inner diameter of the first annular protrusion 11.

[0032] During production, the cover body 2 will not rotate completely to the end, so there is still a certain gap between the ejector pin 22 and the sealing film 4. To prevent the cover body 2 from rotating excessively when not in use, a detachable sealing ring 5 is provided between one end of the cover body 2 close to the tube body 1 and the tube body 1. The sealing ring 5 can be stuck between the cover body 2 and the tube body 1 to prevent the cover body 2 from rotating to the end. Before use, tear off the sealing ring 5, and then the cover body 2 can be rotated to let the ejector pin 22 pierce the sealing film 4.

[0033] In this embodiment, an external thread is provided on the outer wall of the first annular protrusion 11, and an internal thread is provided on the inner wall of the second annular protrusion 23, so that the first annular protrusion 11 and the second annular protrusion 23 are threadedly connected.

[0034] In this embodiment, the length of the second annular protrusion 23 in its axial direction is D1, and the length of the ejector pin 22 in the axial direction of the second annular protrusion 23 is D2, where D1 < D2; in this case, when the ejector pin 22 approaches the sealing film 4 but does not touch it, the second annular protrusion 23 is not screwed in place, and when the second annular protrusion 23 rotates slightly, the ejector pin 22 can pierce the sealing film 4.

[0035] In this embodiment, the inner edge of one end of the ejector pin 22 close to the sealing film 4 has a chamfer to facilitate piercing the sealing film 4.

[0036] In some other embodiments, one end of the ejector pin 22 in contact with the sealing film 4 can also be designed as a tip.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
