The upper fixing plate 41 and the fixing column 43 are in rotary connection and fit with the bottle cap.

Specifically, the self-destroying device is matched with the anti-counterfeiting bottle cap in the following way:

the tamper-evident closure of the present invention includes an upper cap 10, a lower cap 20, and a tamper-evident label 50. The upper cover 10 is movably connected with the lower cover 20; the top wall of the upper cover 10 is provided with an anti-counterfeiting area 11 for attaching an anti-counterfeiting label 50. In this embodiment, the upper cover 10 and the lower cover 20 are both circular, the upper cover 10 includes a top wall and a side wall, the lower end of the side wall of the upper cover 10 is provided with an internal thread, the upper end of the lower cover 20 is provided with an external thread, and the upper cover 10 and the lower cover 20 are rotatably connected by the cooperation of the internal thread and the external thread. The lower end of the lower cap 20 is connected with the bottle mouth, specifically, a buckle 22 is arranged on the outer wall of the lower cap 20, and the lower cap is fixed on the bottle mouth through the buckle 22.

Cavities penetrating the top wall and the bottom wall of the upper cover 10 and the lower cover 20 are respectively arranged in the upper cover and the lower cover 20, and the self-destroying device 40 is movably arranged in the cavities; specifically, the upper fixing plate 41 is provided on the top wall of the upper cover 10. In the present embodiment, the upper fixing plate 41 is circular so as to be rotatably coupled with the upper cover 10, and the upper fixing plate 41 is flush with the top wall of the upper cover 10. The fixed column 43 is positioned inside the upper cover 10 and the lower cover 20, and a clamping block 44 is arranged on the outer wall of the fixed column 43; the inner wall of lower cover 20 is equipped with the lower cover dog 21 with fixture block 44 complex, fixture block 44 and lower cover dog 21 are located same height, and rotate the in-process around the lower cover at self-destruction device and can contact each other, the lower extreme of fixed column 43 is located in the bottle lid through the cooperation card of fixture block 44 and lower cover dog 21, thereby fixed column 43 rotates along a direction in the lower cover, fixture block 44 rotates along with fixed column 43, until contact lower cover dog 21, because lower cover dog 21 is motionless, thereby fixture block 44 can't rotate along this direction once contacting lower cover dog 21 again, also fixed column 43 can't rotate along this direction again. The security tag 50 is fixed to both the upper fixing plate 41 and the top wall of the upper cover 10; in this embodiment, the security tag 50 is a silica gel tag, which is adhered to the top of the upper fixing plate 41 and the upper cover 10, and is filled with random glitter powder particles. The anti-counterfeiting label is in the prior art, and the specific preparation method and principle refer to a patent 'three-dimensional anti-counterfeiting label based on three-dimensional random patterns' applied by the company, and the application number is 201710478243X; or refer to patent 'a three-dimensional anti-counterfeiting label based on a two-dimensional random pattern', and the application number is 2017104781951. One end of the self-destruction rod 422 is connected to the upper fixing plate 41, and the other end extends to the top of the upper cover 10, and the self-destruction rod 422 collides with the anti-counterfeit label 50.

The principle of destroying the anti-counterfeit label 50 by the self-destroying device 40 of the invention is as follows: when the bottle cap is opened, since the upper cap 10 and the lower cap 20 are rotatably connected by screw-fit, the upper cap 10 can be rotated around the lower cap 20 when the upper cap 10 is rotated counterclockwise; since the tamper-proof label 50 is adhered to the top of the upper fixing plate 41 and the upper cover 10 at the same time, that is, the tamper-proof label 50 is equivalent to adhering the upper fixing plate 41 and the upper cover 10 together, the self-destruction device 40 rotates around the lower cover 20 together with the upper cover 10 at the beginning. However, due to the cooperation between the clamping blocks 44 on the fixing columns 43 and the lower cover stop block 21, in the rotation process of the self-destroying device 40, the clamping blocks 44 on the fixing columns 43 are close to and contact with the lower cover stop block 21, and due to the blocking of the lower cover stop block 21, the fixing columns 43 cannot continue to rotate, that is, the self-destroying device 40 cannot continue to rotate, and the upper cover 10 can continue to rotate. Therefore, when the upper cover 10 is rotated anticlockwise by continuously applying force, the upper cover 10 is continuously rotated, the self-destroying device 40 is not rotated, so that the anti-counterfeit label 50 is destroyed, and along with the rotation of the upper cover 10, the anti-counterfeit label 50 is continuously stirred by the fixed self-destroying rod 12, and the structure of the anti-counterfeit label 50 is completely destroyed and cannot be reused. Meanwhile, as the upper cover 10 continues to rotate, the internal and external threads are not matched any more, so that the upper cover 10 can be taken down from the lower cover 20, and meanwhile, the self-destroying device 40 can be pulled out from the lower cover 20 along with the upper cover 10 along the vertical direction, so that the bottle cap can be opened. After the use, the upper cover 10 is rotated clockwise, so that the upper cover 10 and the self-destroying device 40 can be continuously installed on the lower cover 20, and the sealing effect is achieved. The anti-counterfeiting label 50 on the upper cover 10 is destroyed by arranging the self-destruction device 40, so that the anti-counterfeiting bottle cap is prevented from being reused.

Example 2

As shown in fig. 6, the installation position of the self-destruction rod 12 is changed based on embodiment 1, and the self-destruction rod 422 in this embodiment is disposed on the top wall of the upper cover, specifically, one end of the self-destruction rod 422 is connected to the top wall of the upper cover, and the other end extends to the top of the upper fixing plate 41, but is not fixedly connected to the upper fixing plate 41 and is in contact with the anti-counterfeit label 50. Other structures are the same as in embodiment 1.

The principle of destroying the anti-counterfeit label 50 by the self-destroying device 40 is as follows: the self-destruction lever 422 rotates together with the upper cover 10, thereby destroying the security tag 50 on the upper fixing plate 41, which does not rotate, otherwise the same as embodiment 1.

Example 3

As shown in fig. 3 and 8, in this embodiment, the clamping blocks 44 are specifically defined on the basis of embodiment 1 or embodiment 2, specifically in this embodiment, the fixing columns 43 are cylindrical, and 4 clamping blocks 44 are uniformly distributed on the same height position on the outer wall of the fixing column 43; the number of the lower cover stop blocks 21 is 2, and the lower cover stop blocks are symmetrically arranged between the adjacent clamping blocks 44 and are positioned at the same height with the clamping blocks 44. The lower cover stop block 21 consists of a first stop block 211 and a second stop block 212 which are connected with each other, wherein the first stop block 211 is positioned above the second stop block 212, and an included angle is formed between the first stop block 211 and the second stop block 212; the clamping block 44 is clamped at the included angle between the first stop block 211 and the second stop block 212. In the present embodiment, the first stop block 211 is in a horizontal direction, the second stop block 212 is in a vertical direction, the second stop block 212 is connected to the right end of the first stop block 211, and the clamping block 44 is clamped at a right angle between the first stop block 211 and the second stop block 212; the length of the first stopper 211 is less than or equal to the distance between the adjacent stoppers 44. Because of the blocking of the first stopper 211 in the horizontal direction, the self-destruction device 40 cannot be directly pulled out of the lower cover 20 in the vertical direction, and thus, the self-destruction device 40 and the anti-counterfeit label 50 cannot be directly taken down by an illegal person for reuse.

When the bottle cap is opened, when the upper cover 10 is rotated anticlockwise, the self-destroying device 40 rotates around the lower cover 20 along with the upper cover 10, the clamping block 44 clamped at the included angle between the first stop block 211 and the second stop block 212 also rotates anticlockwise, and after the clamping block is staggered with the first stop block 211 in the horizontal direction, the fixing column 43 of the self-destroying device 40 can be pulled out of the lower cover 20 in the vertical direction. Other clamping blocks 44 adjacent to the clamping blocks 44 at the included angle between the first stop block 211 and the second stop block 212 gradually contact the outer side wall of the second stop block 212 along with the rotation of the self-destroying device 40, so that the fixing column 43 cannot continue to rotate due to the blocking of the second stop block 212, that is, the self-destroying device 40 cannot continue to rotate, and the bottle cap can be opened by other operation methods similar to those of the embodiment 1.

In this embodiment, the upper cover clamping block 12 is also annular, and the upper cover clamping block 12 and the upper cover 10 are integrally formed. By arranging the annular boss 45, on one hand, the upper cover 10 can conveniently rotate around the self-destruction device 40; on the other hand, the self-destruct device 40 is prevented from being forcibly pulled out of the upper cover 10.

Example 5

As shown in fig. 1 to 4, in this embodiment, a connection plate 421 is added to the embodiment 1, specifically, the connection plate 421 is disposed in the middle of the top of the upper fixing plate 41, and the self-destruction rod 422 is fixed on the side wall of the connection plate 421; the anti-counterfeit label 50 is disposed on the top of the upper fixing plate 41 and the bottle cap and around the connection plate 421. The top of the connecting plate 421 is also provided with a code scanning area 46. The method is used for attaching a two-dimensional code or a bar code; the user scans the code scanning area 46 through the mobile phone to obtain the anti-counterfeiting App or the WeChat applet, and scans the anti-counterfeiting area 11 through the anti-counterfeiting App or the WeChat applet to obtain the anti-counterfeiting information. In the present embodiment, the connection plate 421 is a cube; the number of the self-destruction rods 422 is 4, and the self-destruction rods are respectively fixed on 4 side walls of the connecting plate 421. The upper fixing plate 41, the connecting plate 421, the self-destroying rod 422, the fixing column 43 and the clamping block 44 of the self-destroying device are all integrally formed.

Example 6

As shown in fig. 2 to 5, this embodiment further defines that the fixing post 43 of the self-destructing device 40 cooperates with the inner cap of the bottle cap on the basis of embodiment 3. Specifically, the bottle cap further includes a sealing cap 60 and a hollow inner cap 30, and the inner cap 30 and the sealing cap 60 are both provided inside the lower cap 20. The inner wall of the lower cap 20 is provided with a pressing block which is in interference fit with the upper end of the inner cap 30, thereby pressing down the inner cap 30. The inner cap 30 comprises a hollow sealing tube 31 and an inner cap clamping block 32 arranged on the outer wall of the sealing tube 31, wherein the outer diameter of the sealing tube 31 is smaller than the inner diameter of the bottle mouth, and the outer diameter of the inner cap clamping block 32 is larger than the inner diameter of the bottle mouth; so that the sealing tube 31 can extend into the bottle mouth, and the inner cap clamping block 32 is clamped on the bottle mouth. A sealing ball 33 is arranged in the sealing tube 31, and the lower end of the sealing tube 31 is contracted inwards; the outer diameter of the sealing ball 33 is smaller than the inner diameter of the upper end of the sealing tube 31 and larger than the inner diameter of the lower end of the sealing tube 31, so that the sealing ball 33 can roll up and down in the sealing tube 31. The sealing cap 60 is provided at the upper end portion of the sealing tube 31, and the outer diameter of the sealing cap 60 is larger than the inner diameter of the sealing tube 31. In the present embodiment, the sealing cap 60 is placed at the upper end opening of the sealing tube 31. The top of the sealing cover 60 is provided with a clamping groove 61; the inner wall of the lower cover 20 is provided with a limiting block 23, and the limiting block 23 is arranged above the clamping groove 61 and corresponds to the clamping groove 61 in position. In the present embodiment, the sealing effect is improved by providing the sealing cover 60. The sealing cover 60 in the present embodiment is placed instead of being fixed to the end of the sealing tube 31, so that a gap is also present between the sealing cover 60 and the sealing tube 31; therefore, to further improve the sealing effect, the fixing column 43 of the present embodiment is located above the sealing cap 60, and when the upper cap 10 is screwed on, the lower end of the fixing column 43 in the self-destroying device 40 contacts and abuts against the sealing cap 60, so that the sealing cap 60 is fully contacted with the sealing tube 31, and the sealing effect of the sealing cap 60 is improved. Meanwhile, the lower end of the fixing column 43 is propped against the sealing cover 60, so that even if the bottle is inclined under the condition that the upper cover 10 is not opened, the sealing ball 33 in the bottle can not prop up the sealing cover 60, and the sealing effect of the sealing cover 60 is effectively improved.

When the liquid in the bottle needs to be poured out, the upper cover 10 and the self-destroying device 50 are removed from the lower cover 20 by adopting the method of the embodiment 2, the lower cover 20 and the inner cover 30 are still fixed on the bottle mouth, the bottle cover is inclined along with the bottle, the sealing ball 33 in the inner cover 30 rolls towards the sealing cover 60, the sealing cover 60 is outwards pushed by the weight of the sealing ball 33, a gap is formed between the sealing cover 60 and the inner cover 30, and the liquid in the bottle can be poured out from the gap. Because the clamping groove 61 matched with the limiting protrusion 23 on the lower cover 20 is arranged on the sealing cover 60, when liquid is poured out, the limiting protrusion 23 is clamped in the clamping groove 61 on the sealing cover 60, the limiting effect on the sealing cover 60 is achieved, the sealing cover 60 cannot slide along the horizontal direction, when the bottle is swung after the liquid is poured out, the sealing cover 60 can return to the original position, and after the upper cover 10 and the self-destruction device 50 are arranged on the lower cover 20, the lower end of the fixing column 43 continuously abuts against the sealing cover 60, so that the sealing effect is continuously achieved.

The above is merely exemplary embodiments of the present invention, and the scope of the present invention is not limited in any way. All technical schemes formed by adopting equivalent exchange or equivalent substitution fall within the protection scope of the invention.
