[0029] Embodiment: As shown in Figures 1-7, a scraper plug is installed at the bottle mouth 51 of the bottle body 50. The scraper plug includes a plug body 10. A scraper lip 20 is provided on the inner wall of the plug body 10. The scraper lip 20 is provided with an exhaust channel 21. The exhaust channel 21 is connected to the inner space 61 of the scraper lip 20 and the outer space 62 of the scraper lip 20. The inner space 61 of the scraper lip 20 refers to the space inside the bottle body 50 with the scraper lip 20 as the dividing line and away from the bottle mouth 51. The outer space 62 of the scraper lip 20 refers to the space inside the bottle body 50 with the scraper lip 20 as the dividing line and close to the bottle mouth 51. A guide surface is provided at the lower end of the plug body 10. The guide surface belongs to the outer side surface of the plug body 10. The guide surface cooperates with the inner side surface of the bottle mouth 51 to guide the scraper plug when it is installed. The scraper plug disclosed in the present application is made of an elastic material, optionally made of NBR (nitrile rubber). Optionally, the plug body 10 is a cylindrical structure with openings at both the upper and lower ends. As shown in Figures 5-7, the scraper plug is installed at the bottle mouth 51 of the bottle body 50. The bottle body 50 can store cosmetics, makeup, or skin care products, such as mascara, liquid lipstick, lip gloss, nail polish, eye shadow, etc. The user dips the brush head 41 of the brush rod 40 into the cosmetic material in the cosmetic container to apply makeup. Before the brush rod 40 and brush head 41 are separated from the cosmetic container, the excess material must be scraped off through the scraper lip 20.

[0030] During use, when the brush rod 40 is inserted into the bottle, the brush rod 40 and the scraper plug divide the space inside the bottle body 50 into the inner space 61 of the scraper lip and the outer space 62 of the scraper lip, and the exhaust channel 21 is connected to the inner space 61 of the scraper lip 20 and the outer space 62 of the scraper lip 20. As shown in Figure 5, the inner space 61 of the scraper lip 20 refers to the space inside the bottle body 50 with the scraper lip 20 as the dividing line and away from the bottle mouth 51, and the outer space 62 of the scraper lip 20 refers to the space inside the bottle body 50 with the scraper lip 20 as the dividing line and close to the bottle mouth 51.

[0031] A guide surface is provided at the lower end of the plug body 10. The guide surface belongs to the outer surface of the plug body 10. The guide surface cooperates with the inner surface of the bottle mouth 51 to guide the scraper plug when the scraper plug is installed. The guidance here means that the scraper plug is installed into the bottle body 50 axially downward along the inner surface of the bottle body 50.

[0032] Due to the presence of the exhaust channel 21 on the scraper lip 20 in the present application, the inner space 61 of the scraper lip and the outer space 62 of the scraper lip are always in a connected state. Therefore, when the brush rod 40 breaks through the scraper lip 20 and enters the interior of the bottle body 50, the air in the inner space 61 of the scraper lip can be discharged from the exhaust channel 21 in time, avoiding the increase of air pressure in the inner space 61 of the scraper lip due to the entry of the brush rod and brush head, and avoiding the splashing of cosmetic materials due to the sudden change of air pressure in the inner space 61 of the scraper lip at the moment when the brush head is separated from the scraper lip.

[0033] As shown in Figures 1, 3, and 4, in one possible embodiment, the plug body 10 includes a first end and a second end, and the scraper lip 20 is disposed between the first and second ends, with the scraper lip 20 being close to the second end of the plug body 10. As shown in Figure 3, the first end of the plug body 10 is the upper end, and the second end is the lower end. The scraper lip 20 is located on the inner sidewall of the plug body 10, and the distance from the scraper lip 20 to the first end is greater than the distance from the second end. In another possible embodiment, the scraper lip 20 is disposed at the second end of the plug body 10.

[0034] The scraper lip 20 extends radially inward along the inner sidewall of the plug body 10 or the second end of the plug body 10. The first end of the scraper lip 20 is fixedly connected to the inner sidewall of the plug body 10 or the second end of the plug body 10. The second end of the scraper lip 20 is a free end and is used for scraping. The first and second ends of the scraper lip 20 can be located in the same radial direction of the plug body 10, as shown in Figures 3 and 4, that is, the scraper lip 20 is arranged perpendicular to the plug body 10.

[0035] The scraper lip 20 can also be arranged at an angle relative to the plug body 10. The scraper lip 20 is funnel-shaped, with the first end of the scraper lip 20 located above the second end of the scraper lip 20, and the second end of the scraper lip 20 is gathered to form a scraper hole. The scraper lip 20 is arranged at an angle toward the bottom of the plug body 10, and the scraper hole is used to scrape the material when the brush rod and brush head pass through.

[0036] An exhaust channel 21 is formed between the first and second ends of the scraper lip 20 and extends through the entire thickness of the scraper lip 20. As shown in FIG4 , the exhaust channel 21 is a through hole provided in the scraper lip 20, and the number of through holes can be one, two, or more. The exhaust channel 21 penetrates the entire thickness of the scraper lip 20 to connect the interior of the bottle below the scraper lip 20 with the exterior of the bottle above the scraper lip 20.

[0037] In one possible embodiment, if two arbitrary points on the scraper lip 20 have thicknesses D1 and D2, respectively, the difference between D1 and D2 is less than Δ, where Δ is the tolerance. The specific value of Δ is determined based on the actual conditions, such as the size, material, precision requirements, and application scenario of the scraper plug. Optionally, Δ is 0.1% to 5% of the average thickness of the scraper lip 20, which facilitates product molding.

[0038] In another possible embodiment, if any two points A and B are located on the scraper lip 20 and the distance between point A and the second end of the scraper lip 20 is less than the distance between point B and the second end of the scraper lip 20, then the thickness of the scraper lip 20 at point A is less than the thickness of the scraper lip 20 at point B. In other words, the scraper lip 20 is thickest at the first end and thinnest at the second end, thereby improving the scraping effect of the scraper lip.

[0039] The plug body 10 has a greater hardness than the scraper lip 20, and the plug body 10 and scraper lip 20 are an integrally molded part. Specifically, the plug body 10 and scraper lip 20 are made of two different materials, with the plug body 10 material having a greater hardness than the scraper lip 20; or the plug body 10 and scraper lip 20 are made of the same material but with different hardnesses. Optionally, the scraper lip 20 is thinner than the plug body 10 and is in the form of a thin sheet.

[0040] As shown in Figures 5-7, a cosmetic container includes a scraper plug, an outer cover 30, a brush rod 40, and a bottle body 50. The scraper plug is mounted on the bottle mouth 51 of the bottle body 50. The first end of the brush rod 40 is fixedly mounted in the outer cover 30, and the second end of the brush rod 40 is fixedly connected to the brush head 41. The outer cover 30 is detachably mounted on the bottle mouth 51 of the bottle body 50. The outer cover 30 and the bottle mouth 51 are detachably connected together by means of screwing, snapping, interference fit, etc. Optionally, as shown in Figure 6, an internal thread 31 is provided on the inner side wall of the outer cover 30, and an external thread 53 is provided on the outer side wall of the bottle mouth 51 that matches the internal thread 31. The outer cover 30 and the bottle mouth 51 are screwed together and fixed by the internal thread 31 and the external thread 53.

[0041] As shown in Figures 3-4, the first end of the plug body 10 extends radially outward to form a ridge 12. The outer wall of the plug body 10 is provided with a fin 11. As shown in Figure 6, the lower end surface of the ridge 12 is in contact with the upper end surface of the bottle mouth 51, and the upper end surface of the fin 11 is in contact with the lower surface of the shoulder of the bottle body 50. The ridge 12 and fin 11 are used to limit the scraper plug in the upper and lower positions, preventing the scraper plug from shifting when the brush head enters and exits the container. The outer wall of the plug body 10 is provided with a rib 13. As shown in Figure 6, the inner wall of the bottle mouth 51 is provided with a groove 52 that cooperates with the rib 13. The cooperation between the rib 13 and the groove 52 further limits the scraper plug in the upper and lower positions.

[0042] The fins 11 are located near the second end of the plug body 10, and the number of the fins 11 is an even number. Optionally, the number of the fins 11 is 2, 4, 6, or 8. As shown in FIG6 , the upper surface of the fin 11 fits against the shoulder of the bottle body 50, and the lower surface of the ridge 12 on the plug body 10 fits against the bottle mouth 51 of the bottle body, that is, the plug body 10 is positioned by the fins 11 and the ridge 12 to prevent the scraper plug from being pulled out when the brush rod 40 is pulled out of the bottle body. The rib 13 on the plug body 10 cooperates with the groove on the bottle body 50. The rib 13 can be a raised bump on the plug body, or it can be a whole circle of raised rings formed along the circumference of the scraper plug. The cooperation between the rib 13 and the groove 12 can further improve the bonding strength between the scraper plug and the bottle body, and can also play a role in positioning the scraper plug when assembling the scraper plug.

[0043] It should be noted that those skilled in the art may make a number of modifications and improvements without departing from the concept of this application, and these modifications and improvements are all within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be based on the appended claims.
