The stopper body 1 is a hollow barrel-shaped structure, which can be cylindrical, polygonal, or barrel-shaped. This embodiment uses a cylindrical stopper body 1 as an example for illustration. The scraping part 2 is made of elastic material and is funnel-shaped. The first end of the scraping part 2 is arranged around the inner wall of the stopper body 1 along its circumference, and the second end of the scraping part 2 gradually narrows to form a scraping hole 5. A brush head 7 is disposed at the top of a rod body 3. The rod body 3 and the brush head 7 can pass through the first end and exit through the scraping hole 5. It should be noted that in this embodiment, the rod body 3 and the brush head 7 have the ability to pass through the first end and exit through the scraping hole 5 during use. The inner diameter of the scraping hole 5 is smaller than the diameter of the rod body 3 and / or smaller than the diameter of the axial projection surface of the brush head 7 in its natural state. The scraping part 2 includes a protruding surface 6, which is in contact with the rod body 3 and the brush head 7. The middle part of the protruding surface 6 is provided with an outward protrusion facing the axis of the scraping part 2.

[0041] In one practical implementation, since the scraper part 2 is made of an elastic material and has a protruding surface 6, when the rod 3 or brush head 7 contacts the protrusion, the scraper part 2 can deform and fit against the rod 3 or brush head 7 with the protruding surface 6. Through the interference contact between the scraper part 2 and the rod 3, or between the scraper part 2 and the brush head 7, a better scraping effect and stronger sealing are achieved. Optionally, in the side cross-section of the scraper part 2, the protruding surface 6 is an arc or a broken line segment composed of multiple planes, such as two, three, or four planes. Optionally, the number of planes is two; in this embodiment, the protruding surface 6 in the side cross-section of the scraper part 2 is an arc as an example.

[0042] In one practical implementation, the protruding surface 6 in the lateral cross-section of the scraper 2 is set as an arc, which can better fit the rod 3 or the brush head 7. Optionally, the inner diameter of the scraper hole 5 is smaller than the diameter of the rod 3 and greater than or equal to the diameter of the axial projection surface of the brush head 7 in its natural state, or the inner diameter of the scraper hole 5 is smaller than the diameter of the axial projection surface of the brush head 7 in its natural state and greater than or equal to the diameter of the rod 3, or the inner diameter of the scraper hole 5 is smaller than both the diameter of the rod 3 and the diameter of the axial projection surface of the brush head 7 in its natural state.

[0043] Optionally, the length of the portion of the protruding surface 6 extending outward from the center of the scraper section 2 to the edge of the scraper hole 5 is 33.3% to 50% of the total length of the scraper section 2. For example, the length of the portion of the protruding surface 6 extending outward from the center of the scraper section 2 to the edge of the scraper hole 5 is 33.3%, 40%, or 50% of the total length of the scraper section 2. It should be noted that the above values ​​of 33.3%, 40%, or 50% are illustrative examples, and this application does not limit the specific values.

[0044] The manufacturing process of the cosmetic bottle cap inner stopper in this embodiment includes integral molding, such as injection molding, glue injection, or thermoforming. It should be noted that the manufacturing process of the cosmetic bottle cap inner stopper in this embodiment can also be other processes, and this application does not limit them.

[0045] The material of the inner stopper of the cosmetic bottle in this embodiment includes plastic or nitrile rubber, etc. It should be noted that the material of the inner stopper of the cosmetic bottle in this embodiment can also be other materials, and this application does not limit them.

The scraper parts 2 are arranged along the axial direction of the plug body 1 and are spaced apart on the inner side of the plug body 1.

[0048] In one practical implementation, the number of scraping sections 2 is set to two to enable more thorough scraping and keep the rod body 3 or brush head 7 clean. Optionally, the inner diameters of the scraping holes 5 are equal.

[0049] Optionally, the cosmetic bottle cap also includes an additional scraping part 8. The diameter of the additional scraping hole 9 of the additional scraping part 8 is greater than or less than that of the scraping hole 5. When the rod body 3 and the brush head 7 are inserted into the cosmetic bottle cap, they first pass through the scraping hole 5 and then through the additional scraping hole 9. In this embodiment, the additional scraping hole 9 of the additional scraping part 8 is larger than that of the scraping hole 5 as an example.

[0050] Example 3

[0055] In one practical implementation, providing two protrusions 4 can further improve the scraping effect, making the scraping cleaner. Optionally, the inner stopper of the cosmetic bottle also includes an additional protrusion 10, which is located on the protruding surface 6 near the scraping hole 5, and the protrusion 4 is located on the protruding surface 6 away from the scraping hole 5. The vertical distance between the vertex of the protrusion 4 and the scraping part 2 is greater than or equal to the vertical distance between the vertex of the additional protrusion 10 and the scraping part 2. In this embodiment, the example given is that the vertical distance between the vertex of the protrusion 4 and the scraping part 2 is greater than the vertical distance between the vertex of the additional protrusion 10 and the scraping part 2. Optionally, the cross-sections of the protrusion 4 and the additional protrusion 10 can be any one of triangle, semicircle, sector, rhombus, trapezoid, and rectangle.
