Anti-falsification bottle cap

Abstract

The present application belongs to the technical field of bottle caps, and particularly relates to a kind of anti-fake bottle caps. The anti-fake bottle cap comprises an outer cap, a chip module, a first inner cap and a cap opening trigger mechanism. The chip module and the outer cap can move synchronously along the axial direction and rotate synchronously along the circumferential direction. The first inner cap is fixed relative to the bottle mouth along the circumferential direction. The cap opening trigger mechanism comprises a conductor strip and two contact points. When the bottle cap is closed, the chip module is in a dormant state. When the bottle cap is opened, the two contact points rotate to contact the conductor strip, so that the chip module is in an activated state and sends normal opening information such as product code, cap opening time and sales location to the background. By counting the normal opening information, the consumption and use of the beverage can be counted. Not only can the product be effectively prevented from being repackaged and put into the market, but also the production and sales plan can be easily arranged. The anti-fake bottle cap also adopts various anti-fake measures to cope with different abnormal opening methods, effectively improving the anti-fake effect.

Description

Technical Field

[0001] This invention relates to the field of bottle cap technology, and in particular to an anti-counterfeiting bottle cap. Background Technology

[0002] Due to the high price of premium bottled products, counterfeit and substandard products are easily found in the market, especially for high-end liquors. There are instances of reusing bottles and caps to pass off inferior goods as superior ones. Therefore, more and more manufacturers are paying attention to anti-counterfeiting measures. Although some existing bottle caps use anti-counterfeiting labels or easily damaged connectors for security, these methods are relatively simple. Anti-counterfeiting labels can be easily peeled off and re-attached, and damaged connectors can be easily replaced, resulting in poor anti-counterfeiting effectiveness. Summary of the Invention

[0003] To improve the anti-counterfeiting effect of bottle caps, the present invention provides an anti-counterfeiting bottle cap.

[0004] An anti-counterfeiting bottle cap provided by the present invention includes:

[0005] The outer cover has a sealed top and an opening at the bottom;

[0006] The chip module is mounted on the inside of the outer cover, and the chip module and the outer cover can move synchronously along the axial direction and rotate synchronously along the circumferential direction.

[0007] The first inner cover is inserted inside the outer cover and is spaced apart below the chip module. The edge of the first inner cover is circumferentially fixed relative to the edge of the bottle mouth.

[0008] The cover-opening trigger mechanism includes a conductor strip and two contact points. The two contact points are located at the bottom of the chip module, and the conductor strip is located at the top of the first inner cover. The two contact points can contact and separate from the conductor strip during the rotation of the chip module.

[0009] When the bottle cap is closed, at least one of the contact points separates from the conductor strip, and the chip module is in a dormant state; when the bottle cap is opened, the chip module rotates synchronously with the outer cap, and two of the contact points rotate to contact the conductor strip, so that the chip module is in an activated state and sends a normal cap opening signal to the background.

[0010] In some embodiments, the bottom of the chip module is further provided with a pop-up switch, the top of the first inner cover abuts against the bottom of the pop-up switch to restrict the pop-up switch from popping up; when the pop-up switch pops up, the chip module is in an active state and sends an abnormal opening signal to the background.

[0011] In some embodiments, the anti-counterfeiting bottle cap further includes:

[0012] The second inner cover has an open top and an open bottom. The top of the second inner cover is sealed and the bottom has an open bottom. The second inner cover is fitted over the outside of the first inner cover.

[0013] The liner is fitted onto the outer peripheral wall of the second inner cover to connect the outer cover and the second inner cover, so that the outer cover and the second inner cover can move synchronously along the axial direction and be relatively fixed in the circumferential direction.

[0014] The inner sleeve includes an upper sleeve, a lower sleeve, and a wine-blocking plate. The wine-blocking plate is fixedly disposed on the inner side of the upper sleeve. The upper sleeve is located on the outer peripheral wall of the first inner cover and is used to connect the first inner cover and the second inner cover. The lower sleeve is used to fit on the outer peripheral wall of the bottle mouth.

[0015] The upper sleeve and the first inner cover can move relative to each other axially and be fixed relative to each other circumferentially; the upper sleeve is connected to the second inner cover by a thread; the lower sleeve and the bottle mouth can move synchronously axially and be fixed relative to each other circumferentially.

[0016] An outer sleeve is fitted onto the outer peripheral wall of the lower sleeve. The top of the outer sleeve supports the bottom of the outer cover. The outer sleeve and the lower sleeve can move synchronously along the axial direction and be relatively fixed relative to each other in the circumferential direction.

[0017] In some embodiments, the bottom of the outer cover is provided with a toothed groove, and the top of the outer cover is provided with an anti-counterfeiting tooth. The anti-counterfeiting tooth is inserted into the toothed groove and breaks when the outer cover rotates relative to the outer cover.

[0018] In some embodiments, a first flange is provided on the outer peripheral wall of the first inner cover near the top, and an upper locking block and a lower locking block are provided on the inner peripheral wall of the second inner cover corresponding to the upper and lower sides of the first flange. The first flange extends between the upper locking block and the lower locking block to restrict the first inner cover from moving axially relative to the second inner cover.

[0019] The inner peripheral wall of the outer cover is provided with a first anti-rotation vertical tooth and a first anti-slip horizontal tooth, and the outer peripheral wall of the inner liner is provided with a second anti-rotation vertical tooth and a second anti-slip horizontal tooth. The first anti-rotation vertical tooth meshes with the second anti-rotation vertical tooth to restrict the inner liner from rotating circumferentially relative to the outer cover, and the first anti-slip horizontal tooth meshes with the second anti-slip horizontal tooth to restrict the inner liner from moving axially relative to the outer cover.

[0020] The inner circumferential wall of the liner is provided with a third anti-rotation vertical tooth and a third anti-slip horizontal tooth, and the outer circumferential wall of the second inner cover is provided with a fourth anti-rotation vertical tooth and a fourth anti-slip horizontal tooth. The third anti-rotation vertical tooth meshes with the fourth anti-rotation vertical tooth to restrict the liner from rotating circumferentially relative to the second inner cover, and the third anti-slip horizontal tooth meshes with the fourth anti-slip horizontal tooth to restrict the liner from moving axially relative to the second inner cover.

[0021] In some embodiments, a connecting sleeve is provided on the inner side of the first inner cover, and a fifth anti-rotation vertical tooth is provided on the inner peripheral wall of the connecting sleeve. The wine-blocking plate is a hollow cylinder with an upward arch, and a sixth anti-rotation vertical tooth is provided on the outer peripheral wall of the wine-blocking plate. The fifth anti-rotation vertical tooth meshes with the sixth anti-rotation vertical tooth so that the first inner cover and the inner sleeve can move relative to each other in the axial direction and be relatively fixed relative to each other in the circumferential direction.

[0022] The outer peripheral wall of the bottle opening is provided with an annular groove, and the inner peripheral wall of the lower sleeve is provided with a corresponding buckle. The top of the buckle is inclined inward relative to the bottom. The buckle is engaged in the annular groove to restrict the lower sleeve from moving axially relative to the bottle opening.

[0023] The outer peripheral wall of the lower sleeve is provided with a limiting strip and a limiting ring platform. The top of the limiting ring platform is connected to the limiting strip, and the bottom of the limiting ring platform extends to the bottom of the lower sleeve. A limiting groove is provided on the limiting ring platform. The inner peripheral wall of the outer sleeve is provided with a strip groove and a limiting ring groove. A third locking block is provided in the limiting ring groove. The limiting strip is locked in the strip groove, the limiting ring platform is locked in the limiting ring groove, and the third locking block is locked in the limiting groove to restrict the outer sleeve from moving axially and rotating circumferentially relative to the lower sleeve.

[0024] In some embodiments, a metal retaining ring is embedded in the inner sleeve. The metal retaining ring includes an annular retaining ring body and a retaining claw disposed on the retaining ring body. The retaining ring body is embedded in the lower sleeve, and the retaining claw is embedded in the buckle.

[0025] In some embodiments, the upper sleeve and the lower sleeve are connected by a transition portion, the transition portion protruding from the outer peripheral wall of the upper sleeve, and the top of the transition portion supporting the bottom of the second inner cover.

[0026] In some embodiments, the top of the outer sleeve is provided with a second flange on the inner side of the outer cover. The second flange protrudes from the top of the outer sleeve and the inner peripheral wall, and the top of the second flange is used to support the inner lining. The transition portion of the inner sleeve is also provided with an outwardly protruding third flange, and the bottom of the second inner cover is provided with an outwardly protruding fourth flange. The bottom of the second flange is used to restrict the third flange and the fourth flange from axially disengaging from the top of the outer sleeve.

[0027] In some embodiments, the anti-counterfeiting bottle cap further includes an inner plug and a check ball disposed in the inner plug. The inner plug includes an upper plug body and a lower plug body. The outer peripheral wall of the upper plug body is attached to the inner peripheral wall of the upper sleeve, and the outer peripheral wall of the lower plug body is attached to the inner peripheral wall of the bottle mouth.

[0028] The anti-counterfeiting bottle cap of this invention, when opened normally, causes the outer cap to rotate relative to the first inner cap, causing the chip module to rotate. During this rotation, two contact points at the bottom of the chip module rotate to contact the conductor strip. The two contact points are connected by the conductor strip, activating the chip module. The activated chip module sends normal opening information such as product code, opening time, and sales location to the backend. By statistically analyzing this normal opening information, the consumption and usage of the beverage can be tracked. This not only effectively prevents the product from being repackaged and reintroduced into the market, thus achieving anti-counterfeiting, but also facilitates the planning of production and sales.

[0029] The anti-counterfeiting bottle cap of this invention can not only send a normal opening signal to the backend via the chip module when the bottle cap is opened normally, but also send an abnormal opening signal to the backend via the chip module when the bottle cap is opened abnormally, or prevent counterfeiting by damaging the bottle cap or bottle opening. This anti-counterfeiting bottle cap employs multiple anti-counterfeiting measures to counter different abnormal opening methods, effectively improving the anti-counterfeiting effect.

[0047] The orientations or positional relationships indicated by terms such as "upper," "lower," "left," "right," "middle," "longitudinal," "lateral," "horizontal," "inner," "outer," "radial," and "circumferential" used in this specification are based on the orientations or positional relationships shown in the accompanying drawings and are only for the purpose of simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0048] like Figure 1-3 As shown, this embodiment provides an anti-counterfeiting bottle cap, including an outer cap 100, a first inner cap 300, a chip module 200, a cap-opening trigger mechanism, a second inner cap 400, an inner liner 500, an inner sleeve 600, an outer sleeve 700, and an inner plug 800. In this embodiment, the top of the outer cap 100 is sealed, and the bottom has an opening. The chip module 200 is snapped into the inner side of the outer cap 100, and it can move synchronously with the outer cap 100 axially and rotate synchronously circumferentially. Preferably, see details below. Figure 4-5 The inner peripheral wall of the outer cover 100 is provided with first locking blocks 110 spaced apart near the top. The outer peripheral wall of the chip module 200 is correspondingly locked inside the first locking blocks 110. The outer peripheral wall of the chip module 200 is provided with second locking blocks 210, which are locked in the intervals of the first locking blocks 110. In this embodiment, the intervals between the first locking blocks 110 are preferably different, so that the second locking blocks 210 have different lengths along the circumferential direction, so that the chip module 200 can be locked in the outer cover 100 at a specific position.

[0049] The chip module 200 in this embodiment has its own internal power supply. A cap-opening trigger mechanism is located at the bottom of the chip module 200. This mechanism controls the chip's activation and sleep states. When the chip module 200 is in the active state, it sends a cap-opening signal to the backend to notify the backend that the bottle of wine has been opened for consumption.

[0050] See details Figure 3 and Figure 6In this embodiment, the top of the first inner cover 300 is sealed, and the bottom of the first inner cover 300 has an opening. The first inner cover 300 is disposed inside the outer cover 100 and spaced below the chip module 200. Specifically, the spaced arrangement in this embodiment means that there is a space between the first inner cover 300 and the chip module 200, and the first inner cover 300 and the chip module 200 do not directly contact each other to avoid interference.

[0051] See details Figure 5-6 In this embodiment, the cover-opening trigger mechanism preferably includes a conductor strip 340 and two contact points 220. The two contact points 220 are spaced apart at the bottom of the chip module 200, and the conductor strip 340 is disposed at the top of the first inner cover 300. The two contact points 220 can rotate with the chip module 200 to contact and separate from the conductor strip 340. When the two contact points 220 are in contact with the conductor strip 340, the two contact points 220 are connected through the conductor strip 340, the internal circuit of the chip module 200 is connected, and the internal power supply of the chip module 200 can supply power to the chip module 200, so that the chip module 200 is in an active state. When at least one contact point 220 is separated from the conductor strip 340, the two contact points 220 cannot be connected through the conductor strip 340, the internal circuit of the chip module 200 cannot be connected, and the chip module 200 is in a dormant state.

[0052] In this embodiment, the bottom of the chip module 200 is also provided with a pop-up switch 230, which is electrically connected to the chip module 200. When the pop-up switch 230 is not popped up, the chip module 200 is in a dormant state; when the pop-up switch 230 pops up, the chip module 200 is in an active state and sends an abnormal cap opening signal to the background. In this embodiment, the top of the first inner cap 300 abuts against the bottom of the pop-up switch 230 to restrict the pop-up switch 230 from popping up, so that the chip module 200 in the normal anti-counterfeiting bottle cap is in a dormant state. It should be noted that the normal cap opening signal and the abnormal cap opening signal in this embodiment include, but are not limited to, information such as product code, cap opening time, and sales location. The specific methods and principles of the pop-up switch 230 and the chip module 200 sending signals to the background are existing technologies and will not be described in detail in this embodiment.

[0053] See details Figure 3 and Figure 8In this embodiment, the second inner cover 400 has an open top and bottom. The second inner cover 400 passes through the inner side of the outer cover 100 and is fitted onto the outer side of the first inner cover 300. The second inner cover 400 and the first inner cover 300 can move synchronously along the axial direction and rotate relative to each other in the circumferential direction. Preferably, a first flange 310 is provided near the top of the outer peripheral wall of the first inner cover 300. An upper locking block 410 and a lower locking block 411 are provided on the inner peripheral wall of the second inner cover 400 corresponding to the upper and lower sides of the first flange 310. The first flange 310 extends between the upper locking block 410 and the lower locking block 411 to restrict the axial movement of the first inner cover 300 relative to the second inner cover 400.

[0054] See details Figure 3 and Figure 9 In this embodiment, the inner liner 500 is fitted onto the outer peripheral wall of the second inner cover 400 to connect the outer cover 100 and the second inner cover 400, enabling the outer cover 100 and the second inner cover 400 to move synchronously axially and rotate synchronously circumferentially. Preferably, the inner peripheral wall of the outer cover 100 in this embodiment is provided with a first anti-rotation vertical tooth 120 and a first anti-slip horizontal tooth 130, with the first anti-slip horizontal tooth 130 located below the first anti-rotation vertical tooth 120. The outer peripheral wall of the inner liner 500 is provided with a second anti-rotation vertical tooth 510 and a second anti-slip horizontal tooth 520, with the second anti-rotation vertical tooth 510 near the top of the second inner cover 400 and the second anti-slip horizontal tooth 520 located below the second anti-rotation vertical tooth 510. The first anti-rotation vertical tooth 120 of the outer cover 100 engages with the second anti-rotation vertical tooth 510 of the inner liner 500 to restrict the circumferential rotation of the inner liner 500 relative to the outer cover 100. The first anti-slip transverse tooth 130 of the outer cover 100 engages with the second anti-slip transverse tooth 520 of the inner liner 500 to restrict the axial movement of the inner liner 500 relative to the outer cover 100.

[0055] In this embodiment, the inner circumferential wall of the liner 500 is provided with a third anti-rotation vertical tooth 530 and a third anti-slip horizontal tooth 540. The third anti-rotation vertical tooth 530 is close to the top of the liner 500, and the third anti-slip horizontal tooth 540 is located below the third anti-rotation vertical tooth. The outer circumferential wall of the second inner cover 400 is correspondingly provided with a fourth anti-rotation vertical tooth 420 and a fourth anti-slip horizontal tooth 430. The third anti-rotation vertical tooth 530 of the liner 500 engages with the fourth anti-rotation vertical tooth 420 of the second inner cover 400 to restrict the liner 500 from rotating circumferentially relative to the second inner cover 400. The third anti-slip horizontal tooth 540 of the liner 500 engages with the fourth anti-slip horizontal tooth 430 of the second inner cover 400 to restrict the liner 500 from moving axially relative to the second inner cover 400. Because the inner liner 500 and the outer cover 100 can move synchronously along the axial direction and be relatively fixed circumferentially, and the inner liner 500 and the second inner cover 400 can move synchronously along the axial direction and be relatively fixed circumferentially, the second inner cover 400 and the outer cover 100 can move synchronously along the axial direction and be relatively fixed circumferentially. To facilitate the inner liner 500 being fitted onto the outer peripheral wall of the second inner cover 400, a notch 550 is also provided on the side wall of the inner liner 500, which gives the inner liner 500 a strong deformation capability. In this embodiment, the first to fourth anti-rotation vertical teeth and the first to fourth anti-slip horizontal teeth have approximately the same height, and their compact structure facilitates mutual positioning.

[0056] See details Figure 3 and Figure 8 In this embodiment, the inner sleeve 600 includes an upper sleeve 610, a lower sleeve 620, and a wine-blocking plate 630. The wine-blocking plate 630 is fixedly disposed inside the upper sleeve 610. The upper sleeve 610 is located between the first inner cover 300 and the second inner cover 400. The lower sleeve 620 is used to fit over the outer side of the bottle neck 900. The first inner cover 300 is placed over the wine-blocking plate 630 to seal the bottle neck 900. The inner circumferential wall of the upper sleeve 610 is fitted over the outer circumferential wall of the first inner cover 300. The upper sleeve 610 is connected to the second inner cover 400 by threads. The first inner cover 300 and the upper sleeve 610 can move relative to each other axially and be fixed relative to each other circumferentially. In this embodiment, an external thread 611 is provided on the outer peripheral wall of the upper sleeve 610, and an internal thread 440 is provided on the inner peripheral wall of the second inner cover 400. The external thread 611 of the upper sleeve 610 engages with the internal thread 440 of the second inner cover 400 so that the second inner cover 400 is screwed onto the inner sleeve 600.

[0057] See details Figure 7 and Figure 10-11In this embodiment, a connecting sleeve 320 is preferably provided on the inner side of the first inner cover 300. The top of the connecting sleeve 320 is fixed to the top of the first inner cover 300. A gap is formed between the outer peripheral wall of the connecting sleeve 320 and the inner peripheral wall of the first inner cover 300. A fifth anti-rotation vertical tooth 330 is provided on the inner peripheral wall of the connecting sleeve 320. In this embodiment, the wine-blocking plate 630 is a hollow cylinder with an upward arch. A sixth anti-rotation vertical tooth 631 is provided on the outer peripheral wall of the wine-blocking plate 630. The fifth anti-rotation vertical tooth 330 of the connecting sleeve 320 engages with the sixth anti-rotation vertical tooth 631 of the wine-blocking plate 630 to restrict the connecting sleeve 320 from rotating circumferentially relative to the upper sleeve 610, so that the first inner cover 300 can move axially relative to the inner sleeve 600 and rotate synchronously circumferentially.

[0058] In this embodiment, the lower sleeve 620 is fitted onto the outer peripheral wall of the bottle mouth 900. The outer peripheral wall of the bottle mouth 900 is provided with an annular groove 910. The inner peripheral wall of the lower sleeve 620 has a latch 621, which engages with the annular groove 910 to restrict axial movement of the lower sleeve 620 relative to the bottle mouth 900. The latches 621 of the lower sleeve 620 are arranged in a circumferential array, with the top of the latches 621 inclined inwards compared to their bottom. The latches 621 engage with the annular groove 910, effectively preventing the inner sleeve 600 from being pulled out of the top of the bottle mouth 900 under external force. Preferably, the lower sleeve 620 in this embodiment has a hollow structure designed at the position corresponding to the latches 621, which not only facilitates the latches 621 engaging with the groove but also saves material on the inner sleeve 600.

[0059] In this embodiment, the upper sleeve 610 and the lower sleeve 620 of the inner sleeve 600 are connected by a transition portion 640. The inner and outer diameters of the lower sleeve 620 are larger than the corresponding inner and outer diameters of the upper sleeve 610, so that the transition portion 640 protrudes from the outer peripheral wall of the upper sleeve 610. The upper sleeve 610, the lower sleeve 620 and the transition portion 640 are in a stepped shape with the upper part smaller than the lower part. The top of the transition portion 640 is used to support the bottom of the second inner cover 400.

[0060] See details Figure 3 and Figure 12 In this embodiment, the outer sleeve 700 is disposed below the outer cover 100 and fitted onto the outer peripheral wall of the lower sleeve 620. The lower sleeve 620 and the outer sleeve 700 can move synchronously along the axial direction and be relatively fixed relative to each other in the circumferential direction. The outer sleeve 700 can rotate relative to the outer cover 100 in the circumferential direction. Preferably, the outer peripheral wall of the lower sleeve 620 is provided with a limiting strip 622 and a limiting ring platform 623. Specifically, the limiting strip 622 is preferably vertically disposed between the buckles 621, and the bottom of the limiting ring platform 623 is arranged at the same height as the bottom of the buckles 621. The top of the limiting ring platform 623 is connected to the limiting strip 622, and the bottom of the limiting ring platform 623 extends to the bottom of the lower sleeve 620.

[0061] In this embodiment, the inner circumferential wall of the outer sleeve 700 has a strip groove 710 corresponding to the limiting strip 622, and a limiting ring groove 720 corresponding to the limiting ring platform 623. The strip groove 710 and the limiting ring groove 720 communicate with each other. The limiting ring groove 720 allows the inner sleeve 600 to pass through the bottom of the outer sleeve 700. The limiting strip 622 is correspondingly embedded in the strip groove 710, and the limiting ring platform 623 is correspondingly embedded in the limiting ring groove 720, thereby limiting the circumferential rotation of the inner sleeve 600 relative to the outer sleeve 700 and limiting the depth to which the inner sleeve 600 passes through the bottom of the outer sleeve 700. In this embodiment, the limiting ring platform 623 is preferably provided with a limiting slot 624, and a third locking block 730 is correspondingly provided in the limiting ring groove 720. The third locking block 730 is engaged in the limiting slot 624 to prevent the inner sleeve 600 from detaching from the bottom of the outer sleeve 700.

[0062] See details Figure 3 In this embodiment, the top of the outer sleeve 700 supports the bottom of the outer cover 100. The top of the outer sleeve 700, inside the outer cover 100, also has a second flange 770. The second flange 770 protrudes from the top of the outer sleeve 700 and the inner peripheral wall, and its top supports the inner liner 500. The transition portion 640 of the inner sleeve 600 also has an outwardly protruding third flange 641, and the bottom of the second inner cover 400 has an outwardly protruding fourth flange 450. The bottom of the second flange 770 restricts the third flange 641 and the fourth flange 450 of the inner sleeve 600 from axially disengaging from the top of the outer sleeve 700. A limiting protrusion 780 is also provided on the inner peripheral wall of the outer sleeve 700. The limiting protrusion 780 is spaced below the third flange 641, so that the second flange 770 is located between the limiting protrusion 780 and the third flange 641.

[0063] In this embodiment, the widths of the limiting strips 622 are preferably different, with one part of the limiting strips 622 being wider than the other part. The width of the strip groove 710 is adaptively adjusted to the corresponding limiting strip 622. The outer peripheral wall of the lower sleeve 620 is provided with a positioning boss 625 at the bottom position, and the inner peripheral wall of the outer sleeve 700 is provided with a corresponding positioning notch 740 at the bottom position. The positioning boss 625 is embedded in the positioning notch 740, so that the inner sleeve 600 and the outer sleeve 700 can be assembled in a specific relative position.

[0064] See details Figure 13In this embodiment, the inner plug 800 is spaced below the first inner cover 300. The inner plug 800 includes an upper plug body 810 and a lower plug body 820. The upper plug body 810 passes through the upper sleeve 610 of the inner sleeve 600, and the outer peripheral wall of the upper plug body 810 is attached to the inner peripheral wall of the upper sleeve 610. The lower plug body 820 is inserted into the bottle mouth 900, and the outer peripheral wall of the lower plug body 820 is attached to the inner peripheral wall of the bottle mouth 900. A check ball may be provided in the inner plug 800 to allow the beverage to be poured out when the bottle mouth 900 is tilted, and to prevent the beverage from evaporating when the bottle mouth 900 is upright. A fifth flange 830 is provided between the upper plug body 810 and the lower plug body 820. The fifth flange 830 extends out of the outer peripheral walls of the upper plug body 810 and the lower plug body 820 to support the bottom of the transition portion 640.

[0065] See details Figure 2 To further enhance the anti-counterfeiting effect of the bottle cap, the bottom of the outer cap 100 in this embodiment is provided with a toothed groove 140, and the top of the outer sleeve 700 is provided with a corresponding anti-counterfeiting tooth 750. Since the outer sleeve 700 remains fixed relative to the bottle opening 900, when the cap is opened, twisting the outer cap 100 relative to the outer sleeve 700 causes the anti-counterfeiting tooth 750 to misalign with the toothed groove 140, resulting in the anti-counterfeiting tooth 750 breaking. See details... Figure 14 To further enhance the connection strength between the lower cylinder and the bottle mouth 900, a metal retaining ring 650 is also embedded in the inner sleeve 600 of this embodiment. The metal retaining ring 650 includes a circular retaining ring body 651 and a retaining claw 652 provided on the retaining ring body 651. The retaining ring body 651 is embedded in the lower sleeve 620, and the retaining claw 652 is embedded in the buckle 621 to enhance the structural strength.

[0066] When the anti-counterfeiting bottle cap is opened normally, an external force is applied to the outer cap 100 to make the outer cap 100 rotate relative to the bottle mouth 900. The rotating outer cap 100 drives the chip module 200, inner liner 500 and second inner cap 400 linked with it to rotate. The first inner cap 300, inner sleeve 600 and outer sleeve 700 remain stationary relative to the bottle mouth 900 in the circumferential direction. During the rotation of the second inner cap 400, the second inner cap 400 moves axially toward the top of the inner sleeve 600 under the action of the thread. The moving second inner cap 400 simultaneously drives the first inner cap 300 to move toward the top of the inner sleeve 600, so that the second inner cap 400 separates from the top of the inner sleeve 600, thereby exposing the wine-stopping plate 630 to the environment for normal drinking.

[0067] During the rotation of the chip module 200, the two contact points 220 at the bottom of the chip module 200 rotate to contact the conductor strip 340. The two contact points 220 are connected through the conductor strip 340, activating the chip module 200. The activated chip module 200 sends normal opening information to the backend. By collecting normal opening information, the consumption and usage of the beverage can be tracked. This not only effectively prevents the product from being repackaged and put back on the market, thus serving as an anti-counterfeiting measure, but also facilitates the planning of production and sales.

[0068] During the rotation of the outer cap 100, the outer cap 100 rotates relative to the outer sleeve 700 and is misaligned, so that the side wall of the broken tooth groove 140 destroys the anti-counterfeiting tooth 750. The destroyed anti-counterfeiting tooth 750 can play an anti-counterfeiting role to prevent the anti-counterfeiting bottle cap from being reused.

[0069] When the anti-counterfeiting bottle cap is opened abnormally, if the entire anti-counterfeiting bottle cap is forcibly pulled out, the buckle 621 on the inner sleeve 600 and the claw 652 of the metal retaining ring 650 will be firmly engaged in the annular groove 910 of the bottle mouth 900, preventing the anti-counterfeiting bottle cap from being pulled out or causing damage to the bottle mouth 900, thus achieving the anti-counterfeiting function. If the outer cap 100 is forcibly pulled out, the chip module 200 will move away from the first inner cap 300 synchronously with the outer cap 100. The pop-up switch 230 at the bottom of the chip module 200 will pop up when it is no longer restrained by the first inner cap 300, and then send an abnormal opening signal through the chip module 200, thus achieving the anti-counterfeiting function.

[0070] The anti-counterfeiting bottle cap of this embodiment can not only send a normal opening signal to the backend via the chip module 200 when the bottle cap is opened normally, but also send an abnormal opening signal to the backend via the chip when the bottle cap is opened abnormally, or prevent counterfeiting by damaging the bottle cap or the bottle opening 900. The anti-counterfeiting bottle cap adopts multiple anti-counterfeiting measures to deal with different abnormal opening methods, effectively improving the anti-counterfeiting effect.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
