[0010] Preferably, a ring groove is arranged on the inner circular surface of the bottle stopper body and located in the mounting hole.

[0011] Through the technical scheme, the plug head part can be clamped in the ring groove, so that the connection is more stable, and the plug head is not easy to be separated from the plug cover.

[0012] Preferably, one side of the ring groove is attached to the bottom of the mounting hole.

[0013] Through the technical scheme, when the ring groove is attached to the bottom of the mounting hole, the edge of the limiting hole can be extended into the ring groove when needed.

[0014] Preferably, the cross-sectional shape of the limiting hole is polygonal, and the corners of the limiting hole are all transitioned by rounded corners.

[0015] Through the technical scheme, the polygonal limiting hole can limit the relative rotation of the plug head in the circumferential direction of the plug head, and the rounded corner transition facilitates injection molding processing.

[0016] Preferably, the cross-sectional shape of the limiting hole is triangular.

[0017] Preferably, the cross-sectional shape of the limiting hole is elliptical.

[0018] Preferably, the cross-sectional shape of the limiting hole is cruciform.

[0019] Preferably, the outer cylindrical surface of the plug cover body is provided with roughness.

[0020] Through the technical scheme, the setting of the roughness can better assist in grasping the bottle cap and prevent slipping.

[0021] The second object of the utility model is to provide a bottle plug, the limiting hole of which can limit the circumferential rotation of the plug head, thereby avoiding slipping between the plug cover and the plug head when rotating the bottle plug.

[0022] The technical scheme of the utility model is: comprising the plug cover structure, the plug head is integrally injection molded in the mounting hole of the plug cover body.

[0023] The technical effects of the utility model mainly embody in the following aspects:

[0024] 1. The limiting hole can limit the circumferential rotation of the plug head, thereby avoiding slipping between the plug cover and the plug head when rotating the bottle plug.

[0035] The specific embodiments of the present application are further described in detail below with reference to the accompanying drawings, so that the technical scheme of the present application is easier to understand and master. Example one

[0036] As shown in the accompanying Figure 1 A plug cover structure, comprising a plug cover body 1, the plug cover body 1 is provided with a mounting hole 3 for mounting the plug head 2. The bottom of the mounting hole 3 is provided with a limiting hole 4, the mounting hole 3 and the limiting hole 4 are concentrically arranged, and the distance from the center of the cross section of the mounting hole 1 to the edge of the cross section of the limiting hole 4 is not equal to two points. That is, the distance from the center of the limiting hole 4 to its edge is not equal, which is not a regular circle. Therefore, compared with a circular hole, the limiting hole 4 can limit the circumferential rotation of the plug head 2, thereby avoiding slipping between the plug cover and the plug head 2 when rotating the plug.

[0037] In addition, in order to facilitate observation during production, the distance from the center of the cross section of the limiting hole 4 to any point on the edge of the cross section of the limiting hole 4 is less than the diameter of the mounting hole 3. In this way, the leakage can be observed directly, and the size of the limiting hole 4 can be measured conveniently with a tool, preventing size deviation and making the injection molding stage more stable.

[0038] Among them, the cross-sectional shape of the limiting hole 4 can be a polygon, and the corners of the limiting hole 4 are all transitioned by a round corner. In this embodiment, the limiting hole 4 is selected as a triangle, and the three corners of the triangle are all transitioned by a round corner, which is convenient for injection molding processing. Example two

[0039] The difference between example two and example one is that a ring groove 5 is provided.

[0040] As shown in the accompanyingFigure 2 and 3 As shown, an annular groove 5 is provided on the inner circular surface of the bottle stopper body, located within the mounting hole 3. The stopper head 2 can be locked within the annular groove 5, making the connection between the two more secure and preventing the stopper head 2 from easily detaching from the cap. The annular groove 5 can be positioned along the axial direction of the cap. In this embodiment, one side of the annular groove 5 is positioned against the bottom of the mounting hole 3.

[0041] Here, when the annular groove 5 is attached to the bottom of the mounting hole 3, the edge of the limiting hole 4 can be extended into the annular groove 5 if necessary. Example 3

[0042] The difference between Example 3 and Example 2 is that the shape of the limiting hole 4 is different.

[0043] As attached Figure 4 As shown, the cross-section of the limiting hole 4 is elliptical. Example 4

[0044] The difference between Example 4 and Example 2 is that the shape of the limiting hole 4 is different.

[0045] As attached Figure 5 As shown, the cross-section of the limiting hole 4 is cross-shaped. Example 5

[0046] As attached Figure 6 and 7 The bottle stopper shown includes the stopper cap structure described in the above embodiment. A stopper head 2 is integrally injection molded into the mounting hole 3 of the stopper cap body 1. Here, the stopper cap can be made of wood or metal. After the stopper cap is manufactured, the stopper head 2 and the stopper cap are integrally injection molded. The molded stopper head 2 will have a limiting block 7 that mates with the limiting hole 4 and a limiting shoulder 8 that mates with the annular groove 5.

[0047] The outer circular surface of the plug body 1 may be provided with textured surface 6 for anti-slip purposes.
