Embodiment: As shown in FIG. 1 and FIG. 2, a multifunctional inner plug includes plug body 110 and cosmetic scraping portion 120. A first end of the cosmetic scraping portion 120 is fixedly connected to the plug body 110, and a second end of the cosmetic scraping portion 120 is a free end. The second end of the cosmetic scraping portion 120 forms cosmetic scraping port 121. A first coupling member is provided on an outer sidewall of the plug body 110. The first coupling member is detachably connected to the outer cap 200. An inner sidewall of the plug body 110 extends inward along a radial direction to form protrusion 114. The outer sidewall of the plug body 110 extends outward along the radial direction to form sealing rib 113. Optionally, the sealing rib 113 is provided at a junction between the plug body 110 and the cosmetic scraping portion 120. As shown in FIG. 7, the inner plug 100 in the present application is provided at a neck of bottle 500 in use. When brush rod 300 and brush head 400 pass through the inner plug 100, the cosmetic scraping port 121 of the inner plug scraps down an excessive cosmetic on the brush rod 300 and the brush head 400. With the first coupling member on the outer sidewall of the inner plug 100, when outer cap 200 covers the inner plug 100, the inner plug is fixedly connected to the outer cap 200 through the first coupling member. The protrusion 114 on the inner sidewall of the plug body 110 is configured to seal the brush rod 300. The sealing rib 113 on the outer sidewall of the plug body 110 is configured to seal the bottle 500. In addition to a cosmetic scraping function, the inner plug in the present application is further detachably connected to the outer cap through the first coupling member. Compared with a conventional cosmetic container in which an outer cap is detachably connected to a bottle, each component in the cosmetic container is manufactured and cooperated more easily. In the present application, the inner plug is in interference fit with the bottle through the sealing rib, and in interference fit with the brush rod through the protrusion. Therefore, the inner plug has desirable sealing performance.

The first coupling member further includes outer screw thread 111, a convex rib or a clamping groove. In a possible implementation, as shown in FIG. 1 and FIG. 2, the first coupling member is the outer screw thread 111. The outer screw thread 111 is provided on the outer sidewall of the inner plug 100 along a circumferential direction. That is, the inner plug is bolted with the outer cap 200 through the outer screw thread 111. In another possible implementation, the first coupling member is the convex rib. The convex rib is provided on the outer sidewall of the inner plug 100 along a circumferential direction. The convex rib is protruded out of the outer sidewall of the inner plug. That is, the inner plug is clamped with the outer cap 200 through the convex rib. In still another possible implementation, the first coupling member is the clamping groove. The clamping groove is provided on the outer sidewall of the inner plug 100 along a circumferential direction. The clamping groove is recessed in the outer sidewall of the inner plug. That is, the inner plug is clamped with the outer cap 200 through the clamping groove.

A rotation stopper is provided on the outer sidewall of the plug body 110. The rotation stopper is located between the first coupling member and the sealing rib 113. As shown in FIG. 2, in a possible implementation, the rotation stopper includes first rotation stopping rib 112. The first rotation stopping rib 112 is provided along an axial direction of the outer sidewall of the plug body 110. Optionally, there are 3-8 first rotation stopping ribs 112 on the outer sidewall of the plug body 110. A distance between two adjacent ones of the first rotation stopping ribs 112 is the same. The inner plug 100 is circumferentially and fixedly connected to the bottle 500 through the first rotation stopping rib. Therefore, rotation between the inner plug and the bottle is effectively prevented, and the inner plug is coaxial to the bottle all the time. In another possible implementation, the rotation stopper includes a protruding point. The protruding point is protruded out of the outer sidewall of the plug body 110. In still another possible implementation, the rotation stopper includes a groove. The groove is recessed in the outer sidewall of the plug body 110. That is, the inner plug 100 can also be circumferentially and fixedly connected to the bottle 500 through the protruding point or the groove.

As shown in FIG. 2, step 115 protruded outward along the radial direction is provided on an outer sidewall of the inner plug 100. The step 115 is provided on the outer sidewall of the inner plug between the first rotation stopping rib 112 and the first coupling member. With interference fit between the step 115 and the bottle 500, the inner plug 100 is assembled in the bottle 500.

Optionally, the cosmetic scraping portion 120 is a cone structure. The cone structure of the cosmetic scraping portion 120 refers to that a cross-sectional area of the first end is greater than a cross-sectional area of the second end in the cosmetic scraping portion 120. When the cosmetic scraping portion 120 has a circular cross-sectional area, a diameter of the first end of the cosmetic scraping portion 120 is greater than a diameter of the second end of the cosmetic scraping portion 120. Sawteeth are arranged at the second end of the cosmetic scraping portion 120. With the sawteeth on the cosmetic scraping port 121, a better cosmetic scraping effect is achieved. A sidewall of the cosmetic scraping portion 120 along the axial direction has an arc-shaped section, an oblique section or a wavy section. When the cosmetic scraping portion 120 has the arc-shaped sidewall, the whole cosmetic scraping portion 120 is a bowl-shaped structure. When the cosmetic scraping portion 120 has the oblique sidewall, the whole cosmetic scraping portion is a truncated cone-shaped structure. When the cosmetic scraping portion 120 has the wavy sidewall, the whole cosmetic scraping portion 120 is a corrugated pipe-like structure. Certainly, the cosmetic scraping portion may also be a hemispheroidal structure, an ellipsoidal structure or other irregular structures.

The outer cap 200 and the inner plug 100 are detachably assembled together through the first coupling member and the second coupling member. In the present application, the inner plug is coupled to the outer cap 200. Compared with a prior art in which an outer cap is cooperated with a bottle, the cosmetic container in the present application has a low cooperation difficulty.

In a first possible implementation, as shown in FIG. 2, the first coupling member is outer screw thread 111. As shown in FIG. 11 and FIG. 12, the second coupling member is inner screw thread 202 matching with the outer screw thread 111. In a second possible implementation, the first coupling member is a first convex rib, and the second coupling member is a second convex rib matching with the first convex rib. In a third possible implementation, the first coupling member is a convex rib, and the second coupling member is a clamping groove matching with the convex rib. In a fourth implementation, the first coupling member is a clamping groove, and the second coupling member is a convex rib matching with the clamping groove. That is, the inner plug 100 and the outer cap 200 can be fixedly connected by bolting or clamping.
