[0036] The connecting member 4 is used to limit the axial displacement of the base 2 and the outer cover 3 after the base 2 and the lower cover 1 are buckled together.

[0037] The connecting member 4 includes a guiding chute 6 and a convex platform 7. The guiding chute 6 is arranged on the outer cover 3. The first end of the guiding chute 6 is closed, and the second end of the guiding chute 6 extends to the bottom of the outer cover 3 to form an opening.

[0038] The convex platform 7 is arranged on the base 2 and is in sliding fit with the guiding chute 6.

[0039] As Figure 1 shown, the guiding chute 6 includes a guiding portion 8 and a limiting portion 9. The opening is located at one end of the guiding portion 8 away from the limiting portion 9, and the limiting portion 9 is arranged horizontally.

[0040] The base 2 includes a first connecting portion 10, a second connecting portion 11 and a third connecting portion 12 with diameters increasing sequentially from top to bottom. The convex platform 7 is arranged on the second connecting portion 11, and the outer diameter of the third connecting portion 12 is adapted to the inner diameter of the lower cover 1.

[0041] The outer cover 3 includes a first outer shell 13 and a second outer shell 14 with diameters decreasing sequentially from top to bottom. The first outer shell 13 is arranged outside the lower cover 1, the second outer shell 14 is arranged inside the lower cover 1, the guiding chute 6 is arranged on the second outer shell 14, and the second outer shell 14 is fitted outside the second connecting portion 11.

[0042] At least one anti-rotation groove 15 is arranged along the axial direction on the inner wall of the lower cover 1.

[0043] A first anti-rotation rib 16 matched with the anti-rotation groove is arranged on the base 2, and a second anti-rotation rib 17 matched with the anti-rotation groove is arranged on the outer cover 3.

[0044] The first anti-rotation rib 16 is arranged on the outer wall of the third connecting portion 12, and the second anti-rotation rib 17 is arranged on the outer wall of the second outer shell 14; the second anti-rotation rib 17 is located above the first anti-rotation rib 16.

[0045] An installation member 18 is fixedly arranged inside the lower cover 1, and a first buckling platform 19 is arranged at the top of the installation member 18.

[0046] An arc-shaped ear plate 23 is arranged at the bottom of the base 2, and a second buckling platform 20 matched with the first buckling platform 19 is arranged on the inner wall of the arc-shaped ear plate 23. Among them, 1. The installation member 18 extends to be connected with the inner wall of the lower cover 1 at the part of the same circumference of the first buckling platform 19 except the first buckling platform 19; 2. Two first buckling platforms 19 are arranged, two connecting parts of the installation member 18 and the lower cover 1 are arranged, and the first buckling platforms 19 are arranged at intervals with the connecting parts of the installation member 18 and the lower cover 1.

[0047] The lower part of the mounting member 18 is adapted to the inner plug 21 for connecting the inner plug 21. Among them, the inner plug 21 can be, but is not limited to, interference-fitted with the mounting member 18.

[0048] Both the outer cover 3 and the base 2 are made of transparent materials. A decorative member 22 is provided at the upper end of the base 2, and the decorative member 22 is located inside the outer cover 3. Among them, the decorative member 22 is provided on the first connecting portion 10

[0049] Working principle: During assembly, first, the outer cover 3 is sleeved on the base 2, and the convex platform 7 extends into the guide chute 6 from the opening; then the outer cover 3 is rotated. When the outer cover 3 rotates, the convex platform 7 enters the end of the guide chute 6 along with the guide chute 6. At this time, the convex platform 7 cooperates with the upper and lower side walls of the guide chute 6 to axially limit the outer cover 3 and the base 2. When the convex platform 7 enters the end of the guide chute 6 along with the guide chute 6, the first anti-rotation rib 16 and the second anti-rotation rib 17 are aligned up and down.

[0050] Then, the outer cover 3 and the base 2 are integrally assembled to the lower cover 1. During this process, the first anti-rotation rib 16 and the second anti-rotation rib 17 cooperate with the anti-rotation groove 15, and the first snap platform 19 and the second snap platform 20 cooperate to complete the assembly of the bottle cap.

[0051] When the bottle cap is in use, due to the cooperation of the first snap platform 19, the second snap platform 20, the snap fit, the guide chute 6 and the convex platform 7, it can prevent the base 2 and the outer cover 3 from separating from the lower cover 1 when being pulled by an external force. If a strong external force is used for pulling, the structures at the first snap platform 19, the second snap platform 20 and / or the guide chute 6 and the convex platform 7 will be damaged, resulting in the bottle cap being damaged and unable to be restored, thereby avoiding external force pulling and preventing counterfeiting of opening the bottle cap.

[0052] At the same time, the anti-rotation groove 15, the first anti-rotation rib 16 and the second anti-rotation rib 17 provided can prevent the base 2 and the outer cover 3 from rotating relative to each other, and further ensure that the convex platform 7 is always within the limiting portion 9 of the guide chute 6, ensuring that the guide chute 6 always limits the vertical displacement of the convex platform 7.

[0053] The mold structure is simple, which reduces the mold manufacturing cost and can meet the aesthetic requirements of the transparent outer cover 3 and the transparent base 2 on the premise of meeting the functionality. It can disperse the longitudinal pulling force, so it can greatly improve the tensile strength of the bottle cap, almost realizes the self-locking and irreversible assembly function. If it is pulled violently, it can damage the cap and cannot be restored twice.

[0054] The components of the bottle cap of the present invention achieve the function of anti-pulling of the bottle cap through the assembly and cooperation of the convex platform, the guide chute and the anti-rotation rib, and the pulling force is transmitted through the convex platform and the guide chute, which can disperse the longitudinal pulling force and greatly improve the tensile strength of the bottle cap; at the same time, by reducing the snap-fit structure between the components of the bottle cap, the mold structure is greatly simplified, and the mold manufacturing cost is reduced.

[0055] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the techniques or knowledge in related fields. Any changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall fall within the protection scope of the appended claims of the present invention.
