[0026] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in conjunction with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0027] Example:

[0028] like Figures 1-6 As shown, this embodiment provides an information anti-counterfeiting bottle cap, comprising:

[0029] The conversion inner cover 1 has a cylindrical shape. Two first limiting posts 11 are provided on the outer side of the top surface of the conversion inner cover 1. A first limiting assembly 12 is provided on the curved side wall surface of the conversion inner cover 1 for limiting the rotation of the outer cover 2 around the axis of the conversion inner cover 1 and causing the outer cover 2 to move away from the conversion inner cover 1 during rotation.

[0030] The outer cover 2 is a cylindrical structure. The outer cover 2 is sleeved on the outside of the conversion inner cover 1. The inner side wall of the outer cover 2 is provided with a second limiting component 21 that rotates and slides with the first limiting component 12. The inner top surface of the outer cover 2 is provided with a second limiting column 22 suitable for connecting and cooperating with the NFC chip 3;

[0031] The NFC chip 3 is arranged on the two first limiting posts 11 and is connected and matched with the second limiting posts 22. When the outer cover 2 is rotated, the second limiting posts 22 can destroy the NFC chip 3, thereby preventing the NFC chip 3 from being reused.

[0032] In another embodiment of the present invention, Figures 1-4As shown, the first limiting assembly 12 comprises a first buckling protrusion 121, a second buckling protrusion 122, two grooves 123 and two sliding channels 124. The two grooves 123 are formed on the top edge of the conversion inner cover 1 and extend downward along the axial direction of the conversion inner cover 1, and the two grooves 123 are symmetrically arranged with respect to the axis of the conversion inner cover 1. The two sliding channels 124 are formed on the side surface of the conversion inner cover 1 and extend through the side surface, and the two sliding channels 124 are circumferentially and equally spaced with respect to the axis of the conversion inner cover 1. Each sliding channel 124 corresponds to a groove 123 and is arranged at the lower part of the groove 123. The left end of each sliding channel 124 communicates with the lower end of the corresponding groove 123, and the left end of each sliding channel 124 is a horizontal segment, the right end gradually inclines to the top surface to form an inclined segment, and the end of the inclined segment is a special-shaped hole structure. An elastically deformable inclined clamping strip 125 is formed at a position corresponding to the left end of the inclined segment in each sliding channel 124, and the two inclined clamping strips 125 are arranged on the upper surface and the lower surface of the sliding channel 124, respectively. The inclination angle of the inclined clamping strip 125 is greater than the inclination angle of the inclined segment, and a receiving space for the force deformation of the inclined clamping strip 125 is formed at a position corresponding to each inclined clamping strip 125 on the upper surface and the lower surface of the sliding channel 124. The force received by the inclined clamping strip 125 comes from between the two inclined clamping strips 125, so that the inclined clamping strip 125 deforms away from the respective inclined direction after being stressed. The first buckling protrusion 121 and the second buckling protrusion 122 are arranged on the curved surface, and the first buckling protrusion 121 and the second buckling protrusion 122 are both arranged on the side of the sliding channel 124 away from the top surface. The first buckling protrusion 121 is arranged at a position directly below the corresponding groove 123, and the second buckling protrusion 122 is arranged at a position directly below the end of the inclined segment of the corresponding sliding channel 124. The distance between the first buckling protrusion 121 and the second buckling protrusion 122 is equal to the distance between the end of the sliding channel 124 connected to the groove 123 and the end of the inclined segment of the sliding channel 124. In this way, when the outer cover 2 moves along the sliding channel 124, it will rotate in the sliding channel 124 and produce axial displacement. The upper surfaces of the first buckling protrusion 121 and the second buckling protrusion 122 are treated with a guide angle, and the lower surfaces of the first buckling protrusion 121 and the second buckling protrusion 122 are horizontal surfaces. In this way, the first buckling protrusion 121 and the second buckling protrusion 122 are matched with the corresponding components in the second limiting assembly 21.

[0033] In another embodiment of the present application, as Figure 5As shown, the second limiting component 21 comprises two protrusions 211 symmetrically arranged relative to the axis of the outer cover 2, and a first inner buckle protrusion 212 and a second inner buckle protrusion 213. The width of the protrusions 211 matches the width of the grooves 123, and the protrusions 211 are slidingly arranged in the corresponding grooves 123 and slide ways 124. The surface of the protrusions 211 near the slide ways 124 is treated with an inclined angle, which facilitates the movement of the protrusions 211 on the inclined sections of the slide ways 124 and the deformation of the inclined clamping strips 125. The first inner buckle protrusion 212 and the second inner buckle protrusion 213 are arranged below the protrusions 211. The first inner buckle protrusion 212 is arranged directly below the protrusions 211. The vertical distance between the first inner buckle protrusion 212 and the second inner buckle protrusion 213 is the same as the vertical distance between the first buckle protrusion 212 and the second buckle protrusion 213. The lower surfaces of the first inner buckle protrusion 212 and the second inner buckle protrusion 213 are treated with an inclined angle, which facilitates the cooperation with the first buckle protrusion 121 and the second buckle protrusion 122. When the protrusions 211 are located at the connection between the grooves 123 and the slide ways 124, the first inner buckle protrusion 212 is connected with the first buckle protrusion 121, and the second inner buckle protrusion 213 is connected with the second buckle protrusion 122. When the protrusions 211 rotate along the slide ways 124 and pass through the inclined clamping strips 125 to reach the end of the slide ways 124, the first inner buckle protrusion 212 is connected with the second buckle protrusion 122, and the second inner buckle protrusion 213 and the first buckle protrusion 121 are not connected.

[0034] In another embodiment of the present application, as shown in Figure 2 The top surface of the conversion inner cover 1 is provided with an annular groove 13. The annular groove 13 is located outside the two first limiting columns 11. During installation, the second limiting column 22 extends through the second circular hole 32 into the annular groove 13. The axis of the annular groove 13 coincides with the axis of the conversion inner cover 1.

[0035] The annular groove 13 increases the movement space of the second limiting column 22 and leaves a conversion gap between the outer cover 2 and the conversion inner cover 1.

[0036] In another embodiment of the present application, as shown in Figure 6As shown, the second limiting column 22 is provided with two, the cross section of the NFC chip 3 is circular, two first circular holes 31 are opened on the NFC chip 3 corresponding to the positions of the two first limiting columns 11, two second circular holes 32 are opened on the NFC chip 3 corresponding to the positions of the two second limiting columns 22, the two first circular holes 31 are arranged at equal intervals in the circumferential direction relative to the axis of the NFC chip 3, the two second circular holes 32 are arranged at equal intervals in the circumferential direction relative to the axis of the NFC chip 3, the NFC chip 3 is matched with the first limiting column 11 through the first circular hole 31, and the two second limiting columns 22 on the outer cover 2 are clamped into the two second circular holes 32; The lines on the NFC chip 3 are routed around the two first circular holes 31 and the two second circular holes 32 respectively. The diameter of the second circular hole 32 is greater than the diameter of the first circular hole 31. The second limiting column 22 extends into the annular groove 13 after passing through the second circular hole 32, realizing the connection gap limiting of the outer cover 2 and the conversion inner cover 1.

[0037] The lines on the NFC chip 3 are routed around the two first circular holes 31 and the two second circular holes 32 respectively, when rotating the outer cover 2, during the whole rotation process, the second limiting column 22 of the outer cover 2 will rotate in the annular groove 13 of the conversion inner cover 1, directly damaging the lines around the first circular hole 31 and the second circular hole 32 of the NFC chip 3, resulting in subsequent inability to identify the NFC chip 3 and inability to use twice.

[0038] In another embodiment of the application, as Figure 1 and Figure 7As shown, the inner cover 4 is a cylindrical structure, and a skirt 41 is radially outwardly extended at the outer edge of the lower end of the inner cover 4, the diameter of the skirt 41 is 27-29 mm, preferably 28.4 mm in the embodiment, and two first anti-rotation ribs 42 are equidistantly arranged on the curved outer sidewall of the inner cover 4 along the circumferential direction of the inner cover 4, the first anti-rotation ribs 42 are arranged close to the skirt 41, and two annular protruding strips 43 are arranged on the curved outer sidewall of the inner cover 4 along the circumferential direction of the inner cover 4, the two annular protruding strips 43 form two annular clamping grooves in cooperation with the outer diameter of the inner cover 4, the axis of the annular protruding strips 43 coincides with the axis of the inner cover 4, and the annular protruding strips 43 are arranged above the first anti-rotation ribs 42; a plurality of second anti-rotation ribs 14 and two rows of arc-shaped clamping strips 15 are arranged on the curved inner side of the conversion inner cover 1, the number of each row of arc-shaped clamping strips 15 is four, the arc-shaped clamping strips 15 are located on the same horizontal plane, the lower surface of the arc-shaped clamping strips 15 is an arc surface, which is convenient for clamping into the clamping grooves between the annular protruding strips 43, the length direction of the second anti-rotation ribs 14 is arranged in parallel with the axis of the conversion inner cover 1, the second anti-rotation ribs 14 are equidistantly arranged along the circumferential direction of the axis of the conversion inner cover 1, the axis of the arc-shaped clamping strips 15 coincides with the axis of the conversion inner cover 1, the arc-shaped clamping strips 15 are equidistantly distributed along the circumferential direction of the axis of the conversion inner cover 1, the second anti-rotation ribs 14 are arranged close to the lower end of the conversion inner cover 1, the arc-shaped clamping strips 15 are located on the upper part of the inner side of the conversion inner cover 1, the number of the second anti-rotation ribs 14 is half of the number of the first anti-rotation ribs 42, when the conversion inner cover 1 is clamped on the outside of the inner cover 4, each second anti-rotation rib 14 is arranged between adjacent first anti-rotation ribs 42, and the two rows of arc-shaped clamping strips 15 are clamped into the two clamping grooves between the annular protruding strips 43; the inner sidewall of the inner cover 4 is provided with a screw inner thread which is matched with the bottle mouth 6.

[0039] The conversion inner cover 1 is limited in the circumferential direction by the cooperation of the second anti-rotation ribs 14 and the first anti-rotation ribs 42 of the inner cover 4, and is limited in the axial direction by the cooperation of the arc-shaped clamping strips 15 and the annular protruding strips 43, so as to realize the synchronous rotation between the conversion inner cover 1 and the inner cover 4, and realize the connection relationship between the conversion inner cover 1 and the bottle mouth 6 through the inner cover 4.

[0040] In another embodiment of the present application, as Figure 1 and Figure 8As shown, it also includes a lower sleeve 5, which is a cylindrical structure. The lower sleeve 5 is passed through at both ends along its axis. The inner cover 4 is sleeved in the lower sleeve 5. The inner diameter of the upper end of the lower sleeve 5 is smaller than the inner diameter of the lower end. The diameter of the lower end of the outer portion of the lower sleeve 5 is also larger than the diameter of the upper end. The inner diameter of the lower end of the lower sleeve 5 is larger than the diameter of the skirt 41. The top opening of the lower sleeve 5 is formed with a circle of bosses inwardly for easy cooperation with the skirt 41 of the inner cover 4. The diameter of the end with the smaller inner diameter of the boss of the lower sleeve 5 is smaller than the diameter of the skirt 41. The inner wall of the end with the larger inner diameter of the lower sleeve 5 is provided with a plurality of clamping platforms 51. The clamping platforms 51 are evenly spaced around the axis of the lower sleeve 5. The lower surface and side surface of the clamping platform 51 are beveled. The bevel is arc-shaped. The upper surface of the clamping platform 51 is flat. The lower sleeve 5 is sleeved on the bottle mouth 6 and is clamped on the bottle mouth 6 by the clamping platform 51. The inner diameter of the top of the lower sleeve 5 is 26-28 mm, preferably 27.8 mm in this embodiment.

[0041] The setting of the lower sleeve 5 facilitates further limiting the inner cover 4. The clamping platform 51 on the lower sleeve 5 cooperates with the bottle mouth 6 to fix itself. The upper end of the lower sleeve 5 is limited and matched with the skirt 41 of the inner cover 4, which also plays a role in hiding the inner cover 4, preventing the user from directly twisting the inner cover 4 with external force, thereby causing the inner cover 4 to break away from the bottle mouth 6 and be removed by threaded rotation, thereby circumventing the setting of the anti-counterfeiting structure between the outer cover 2 and the conversion inner cover 1 in this application, so that the user can only twist the outer cover 2 on the outside to drive the entire cover body to rotate. Twisting the conversion inner cover 1 will forcibly drive the skirt 41 of the inner cover 4 to break free from the constraint of the top of the lower sleeve 5. Continuing to turn the knob, the information anti-counterfeiting bottle cap can be fully opened to pour wine.

[0042] The working process and principle of the above structure are as follows:

[0043] The information anti-fake bottle cap is assembled in order from the lower end surface of the lower sleeve 5 to the top, the inner cap 4 is sleeved in the lower sleeve 5, and is screwed with the bottle mouth 6 through the internal screw thread, then the conversion inner cap 1 is sleeved outside the inner cap 4, the second anti-rotation ridge 14 of the conversion inner cap 1 is clamped between the first anti-rotation ridge 42 on the outer surface of the inner cap 4, and the arc-shaped clamping strip 15 is clamped into the clamping groove of the annular protruding strip 43, so that the assembly between the inner cap 4 and the conversion inner cap 1 is realized; the special NFC chip 3 is installed on the top of the conversion inner cap 1 according to the corresponding matching of the two first circular holes 31 and the two first limiting columns 11, the outer cap 2 is assembled with the conversion inner cap 1, because of the existence of the convex block 211 of the outer cap 2 and the groove 123 of the conversion inner cap 1, the convex block 211 is assembled into the slide 124 along the groove 123, at the same time, in this assembly process, the second limiting column 22 of the outer cap 2 can directly pass through the second circular hole 32 of the special NFC chip 3 and reach the annular groove 13 on the top of the conversion inner cap 1, the first inner buckle position protrusion 212 and the second inner buckle position protrusion 213 of the outer cap 2 are buckled with the first buckle position protrusion 121 and the second buckle position protrusion 122 of the conversion inner cap 1 respectively, the first inner buckle position protrusion 212 and the second inner buckle position protrusion 213 of the outer cap 2 are buckled with the first buckle position protrusion 121 and the second buckle position protrusion 122 of the conversion inner cap 1, so that the outer cap 2 cannot move back; the whole upper cap structure is assembled;

[0044] When the information anti-counterfeiting bottle cap is opened by the knob, due to the friction between the inner cap 4 and the bottle mouth 6, the lower sleeve 5 and the inner cap 4 present a state that the skirt 41 is closely attached to the top opening of the lower sleeve 5. Due to the size of the skirt 41 of the inner cap 4 being larger than the inner diameter size of the top of the lower sleeve 5, it cannot be easily unscrewed, so the outer cap 2 of the information anti-counterfeiting bottle cap will rotate first. The protrusion 211 of the outer cap 2 first moves from the horizontal section to the front end of the inclined clamping strip 125 along the slide 124. The outside of the inclined clamping strip 125 is a hollow state at the accommodating space. Under the action of the force provided by the protrusion 211, the inclined clamping strip 125 will deform, and the protrusion 211 will break through the inclined clamping strip 125 to reach the end of the inclined section of the slide 124. In this process, the first inner buckle position protrusion 212 of the outer cap 2 will move to the second buckle position protrusion 122 below to be buckled two by two, and the height of the whole cap is increased, so that the customer can directly see the height change of the information anti-counterfeiting bottle cap with the naked eye. After completion, the inclined clamping strip 125 returns to the initial state, blocking the protrusion 211, so that 211 cannot return to the horizontal section of the slide 124; during the whole rotation process, the second limiting column 22 of the outer cap 2 will rotate in the annular groove 13 of the conversion inner cap 1, directly damaging the circuit around the first circular hole 31 and the second circular hole 32 of the NFC chip 3, causing the subsequent NFC chip 3 to be unable to be identified, and unable to be used again; due to the fact that there is no space for the protrusion 211 to continue to move at the slide 124, continuing to twist will forcibly bring the inner cap 4 out of the constraint of the lower sleeve 5, and continuing to twist can drive the inner cap 4 to rotate along the bottle mouth 6, completely opening the information anti-counterfeiting bottle cap to pour wine.

[0045] Finally, it should be noted that: the above only describes the preferred embodiments of the present application and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
