Chip anti-counterfeiting bottle cap and wine bottle

Abstract

This invention discloses a chip-based anti-counterfeiting bottle cap and bottle, belonging to the field of bottle cap anti-counterfeiting technology. The bottle cap includes an inner cap that cooperates with a dispensing spout assembly and remains stationary when opened; a rotatable middle cap; an outer cap fixed to the middle cap and rotating synchronously therewith; and an electronic tag fixed to the inner cap and including a chip. The key feature is that the inner top surface of the outer cap has a clearance portion corresponding to the chip when the bottle cap is not opened, and a destructive portion surrounding the clearance portion. When the bottle cap is opened, the middle and outer caps rotate relative to the stationary inner cap, causing the destructive portion to mechanically interfere with the chip, thereby physically crushing or cutting the chip. This invention, by irreversibly destroying the chip upon opening the bottle, eliminates the risk of core anti-counterfeiting information being transferred and reused, providing extremely high anti-counterfeiting security.

Description

Technical Field

[0001] This invention relates to the field of bottle cap technology, and more particularly to an anti-counterfeiting bottle cap with an electronic tag, specifically an anti-counterfeiting bottle cap and bottle that can physically destroy the electronic tag chip when opened. Background Technology

[0002] With the development of the commodity economy, the demand for anti-counterfeiting measures for high-end consumer goods, especially premium liquors, is increasing. Integrating electronic tags (such as NFC or RFID tags) with unique identification information onto bottle caps has become a mainstream anti-counterfeiting technology. Consumers or inspectors can verify the authenticity of products by reading the information within the electronic tag.

[0003] In the prior art, Chinese invention patent CN201621196993.5 discloses an anti-counterfeiting outer cap assembly. Its technical solution involves the electronic tag being rubbed against the top cap by the relative rotation of the outer cap body and the electronic tag fixing component when the bottle cap is opened, thereby damaging the electronic tag and achieving the anti-counterfeiting purpose. However, this design has a major drawback: its destructive effect is mainly concentrated on the antenna part of the electronic tag. Since the antenna is usually a wire printed or etched on a flexible substrate, it has a large area and is relatively fragile, easily damaged by the shearing or frictional forces generated by the relative movement, rendering the tag unreadable.

[0004] However, the core security vulnerability of this design lies in the fact that the "brain" of the electronic tag—the chip itself—is not effectively destroyed. It is still possible to use specialized technical means to peel this intact chip, which carries genuine product identification information, from the damaged original antenna and then resolder or bind it to a new counterfeit antenna, thereby "cloning" a fully functional counterfeit electronic tag and using it on counterfeit products. Although this "chip transfer" counterfeiting method has a high technical threshold, it is frequently used due to high profits, significantly weakening the security of existing anti-counterfeiting technologies. Summary of the Invention

[0005] The present invention aims to overcome the technical defects of existing electronic tags where only the antenna is damaged and the chip can still be transferred and reused. It provides an anti-counterfeiting bottle cap and wine bottle that can apply irreversible physical damage to the core chip of the electronic tag through mechanical structure linkage when the bottle cap is opened for the first time, thereby preventing the chip from being reused.

[0006] A chip-based anti-counterfeiting bottle cap, comprising:

[0007] Wine spout assembly;

[0008] Outer cover assembly, the outer cover assembly comprising:

[0009] The middle cover is rotatably fitted onto the spout assembly;

[0010] The inner cap is provided at the upper opening of the middle cap, and the inner cap is provided with an anti-rotation structure for cooperating with the spout assembly during the initial stage of opening the bottle cap.

[0011] The outer cover is fixedly connected to the middle cover and rotates synchronously with it.

[0012] An electronic tag, which is fixed to the top surface of the inner cover, the electronic tag including a chip;

[0013] The outer cover has an inner top surface facing the electronic tag, and the inner top surface is provided with a clearance part and a damage part;

[0014] When the bottle cap is not opened, the clearance portion corresponds to the position of the chip to provide a gap between the chip and the inner top surface;

[0015] When the middle cover and the outer cover are opened and rotated relative to the inner cover, the clearance part deviates from the position of the chip, and at the same time, the damaging part mechanically interferes with the chip to physically damage the chip.

[0016] Compared with the prior art, the present invention has the following significant advantages:

[0017] 1. This invention directly attacks the core of the electronic tag—the chip—rather than merely the peripheral antenna. Once the chip is physically damaged, the unique identification information stored inside will be permanently lost, rendering the chip completely ineffective and fundamentally eliminating the possibility of transferring it to counterfeit products for secondary use.

[0018] 2. Through an ingenious "grinding disc" or "shearing" mechanical structure design, the powerful rotational torque generated when the bottle cap is opened is used to drive the destruction process, ensuring reliable and thorough destruction of tiny but robust chips.

[0019] 3. While destroying the chip, the antenna is usually torn and there are irreversible opening marks (such as gaps that cannot be reset), which constitutes a multi-dimensional and three-dimensional anti-counterfeiting system of "chip destroyed + label damaged + appearance changed", which has a good anti-counterfeiting effect.

[0020] 4. The chip destruction process is completed instantly during the user's normal bottle opening action, without requiring any additional learning or operation from the user, and the whole process is smooth and natural. Attached Figure Description

[0091] To make the above-mentioned objects, features, and advantages of the present invention more readily understood, specific embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the specific details described below are only a part of the embodiments of the present invention, and the present invention can be implemented in many other embodiments different from those described herein. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0092] In this document, when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The directional terms such as "front," "back," "up," and "down" are defined based on the location of the components in the accompanying drawings and their relationship to each other, and are merely for clarity and convenience in expressing the technical solution. It should be understood that the use of these directional terms should not limit the scope of protection claimed in this invention.

[0093] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0094] In this article, "opening rotation direction" refers to the circumferential direction in which the outer cover and middle cover rotate relative to the inner cover when the chip is opened. "Front side" and "rear side" are based on this direction. "Physical damage" refers to irreversible damage to the chip caused by applying pressure, shearing, impact, grinding, or other forces, resulting in the silicon substrate breaking, internal circuit breakage, or damage to the packaging structure, thereby causing the chip to lose its data reading and / or processing functions.

[0095] Example 1

[0096] See Figure 1 The chip-based anti-counterfeiting bottle cap in Embodiment 1 of the present invention mainly includes a wine dispensing nozzle assembly, an outer cap assembly, and an electronic tag 90.

[0097] Reference Figure 1 , 3 4. The wine outlet assembly mainly consists of an inner stopper 10, a glass bead 20, a one-way valve 30, a wine outlet 40, and an outer sleeve 50.

[0098] The spout 40 includes an outer spout sleeve 41 and an inner spout sleeve 42, which are connected by a plurality of radially extending connecting ribs 43. The outer circumferential surface of the outer spout sleeve 41 is provided with external threads 41b for screwing into the outer cap assembly. The spout 40 also has anti-rotation protrusions or anti-rotation recesses that mate with the inner cap 70. As an example, the top surface of the outer spout sleeve 41 has a plurality of first anti-rotation protrusions 41a; preferably, the first anti-rotation protrusions 41a are cylindrical and extend axially along the spout 40. The inner spout sleeve 42 has a plurality of second anti-rotation recesses 42a; as an example, the second anti-rotation recesses 42a are axially extending grooves provided on the outer side wall of the inner spout sleeve 42.

[0099] The inner stopper 10 includes an inner stopper body 12, a shoulder 16, and a neck 18. The inner stopper body 12 and the shoulder 16 are used to seal with the bottle mouth. The neck 18 is inserted into the outer nozzle sleeve 41 and is sealed with the outer nozzle sleeve 41.

[0100] Glass beads 20 and one-way valves 30 are installed sequentially from bottom to top inside the inner stopper 10. Glass beads 20 and one-way valves 30 serve to prevent backflow and control the wine output. Their specific structure can be found in [reference needed]. Figure 1 As shown.

[0101] The outer casing 50 has a cylindrical structure, with its upper end pressing against the convex ring of the spout 40. The outer casing 50 mainly serves a decorative function.

[0102] The outer cover assembly includes an inner cover 70, a middle cover 60, and an outer cover 80.

[0103] Reference Figure 1 The middle cover 60 is a cylindrical structure with openings at both ends, and its inner wall is provided with an internal thread 61 that mates with the external thread 41b on the outer nozzle sleeve 41.

[0104] Reference Figure 1 , 56. The inner cover 70 includes a fixing body 72 and an insert 74 extending downward from near its edge. The fixing body 72 on the outer side of the insert 74 has several first anti-rotation recesses 74a, and the inner circumferential surface of the insert 74 has several second anti-rotation protrusions 74b. In the assembled state, the fixing body 72 of the inner cover 70 covers the upper opening of the middle cover 60. The first anti-rotation recesses 74a and second anti-rotation protrusions 74b on the inner cover 70 engage one-to-one with several first anti-rotation protrusions 41a and several second anti-rotation recesses 42a on the spout 40. This engagement forms an anti-rotation structure, the function of which is to ensure that the inner cover 70 is held in place by the spout 40 and cannot rotate with the middle cover 60 during the initial rotation phase of opening the bottle cap, thus creating the necessary conditions for the subsequent relative movement that could damage the chip. Furthermore, after the initial opening, due to the complexity of the threaded movement, it is almost impossible for the user to precisely insert the first anti-rotation protrusion 41a back into the tiny first anti-rotation recess 74a when screwing the cap back on. This will result in the outer cap assembly not being able to be fully screwed back on, leaving a visible gap between its lower end face and the spout assembly, thus clearly indicating to the consumer that "this bottle has been opened".

[0105] The outer cap 80 is a closed cap that fits over the middle cap 60. A fixed connection structure securely locks the outer cap 80 and the middle cap 60 together, ensuring that the outer cap 80 rotates synchronously with the middle cap 60 when the bottle is opened. As a specific example, the fixed connection structure can be a groove 62 on the outer wall of the middle cap 60 and a protrusion 82 on the inner wall of the outer cap 80 that engages with the groove 62. The engagement of the protrusion 82 with the groove 62 securely connects the outer cap 80 and the middle cap 60.

[0106] The electronic tag 90 includes a substrate 92 and a chip 94 and an antenna disposed on the substrate 92, with the chip 94 protruding from the upper surface of the substrate 92. The electronic tag 90 is fixed to the top surface of the fixing body 72 of the inner cover 70. On the inner top surface of the outer cover 80 (i.e., the side facing the electronic tag 90), a clearance groove 80a is machined at the predetermined position of the chip 94 (see...). Figure 1 , 2 And 7, 8, for example, a square relief groove with a depth of about 0.5 mm and a profile slightly larger than the chip. The inner top surface of the relief groove 80a, which is not removed, forms a flat, rigid breaking part. This structure is like a miniature grinding disc. In the sealed state with the cap closed, the relief groove 80a is precisely aligned and covers the chip 94. The chip 94 is "hidden" in the groove, and there is a safe gap between it and the inner top surface of the outer cap 80. Therefore, the chip is protected from damage by force, whether during the encapsulation process or during transportation.

[0107] Besides being the area surrounding the clearance slot, the breaking part can take many other equivalent forms. For example, the breaking part can be one or more protrusions, reinforcing ribs, or teeth that strike the chip like a hammer during rotation. The breaking part can be a surface with a rough texture or abrasive coating, damaging the chip through grinding. The breaking part can be a bevel or cam structure that pries or squeezes the chip during rotation, causing it to break.

[0108] The clearance area does not necessarily have to be a groove; it can also be a raised enclosure surrounding the chip, as long as it can form a safe gap.

[0109] In some embodiments, the base 92 of the electronic tag 90 is designed to be attached at one end to the stationary inner cover 70, and the other end has a tail 92a (see...). Figure 9 If the tail 92a is attached to the side wall of the component that rotates with the middle cover 60, then at the moment of relative rotation, the antenna will also be torn off at the same time.

[0110] The assembly method of the anti-counterfeiting bottle cap of the present invention is as follows:

[0111] First, place the glass beads and one-way valve into the inner stopper in sequence. Then, press the protruding neck of the inner stopper into the outer sleeve of the spout. The inner stopper and spout are integrated through an interference fit and cannot be separated. Next, install the outer sleeve. Then, screw the middle cap onto the spout, and then assemble the inner cap. Align the second anti-rotation recess and the second anti-rotation protrusion on the inner cap with the first anti-rotation protrusion and the first anti-rotation recess on the spout, respectively. Press the inner cap downwards so that the second anti-rotation recess and the second anti-rotation protrusion respectively engage with the first anti-rotation protrusion and the first anti-rotation recess. This completes the assembly of the inner cap. Then, fix the electronic tag to the top surface of the assembled inner cap. The electronic tag can be fixed to the top surface of the inner cap by adhesive or other methods. The tail of the electronic tag is fixed to the outer surface of the middle cap. After the electronic tag is fixed, install the outer cap. First, align the clearance groove on the outer cap with the chip, and then press the outer cap downwards axially so that the locking protrusion on the outer cap engages with the locking groove on the middle cap.

[0112] The opening and anti-counterfeiting implementation process of this invention:

[0113] 1. Initial state: The bottle cap is screwed tightly onto the bottle neck. The anti-cavity groove 80a inside the outer cap 80 is precisely aligned with the chip 94 on the inner cap 70, and the chip is in a safe state. The inner cap 70 and the spout 40 are securely engaged by the aforementioned anti-rotation structure.

[0114] 2. Initial Opening: When the user rotates the middle cover 60 in the opening direction, relative motion is generated. Due to the anti-rotation structure, the inner cover 70 and the electronic tag 90 and chip 94 fixed on it cannot rotate and remain stationary. However, the middle cover 60 and the outer cover 80 fixed to it begin to rotate relative to the inner cover 70. This relative rotation causes the clearance groove 80a on the inner top surface of the outer cover 80 to instantly rotate away from its original position. The originally flat and rigid fracture surface, like a rotating millstone, immediately grinds over and contacts the stationary chip 94 below. Since the chip 94 is a brittle silicon-based material, under the huge shear force and compressive stress brought about by the rotation, it will be immediately squeezed, sheared, or crushed and shattered, and its internal circuit structure will suffer irreversible physical destruction. As mentioned earlier, the antenna can be torn simultaneously in this process.

[0115] 3. Opening complete: Immediately after the chip is destroyed, as the middle cover 60 continues to rotate and rises along the internal thread 61, the anti-rotation structure of the inner cover 70 and the spout 40 will disengage. At this time, the entire outer cover assembly will be screwed out of the bottle mouth as a whole, completing the opening action.

[0116] Through the above design, this invention achieves instantaneous, reliable, and irreversible physical destruction of the core chip of the electronic tag during normal bottle opening. Once opened, the chip is rendered unusable, completely eliminating the possibility of transfer or reuse, thus elevating the anti-counterfeiting level to a whole new level.

[0117] Example 2

[0118] The basic structure of the chip anti-counterfeiting bottle cap in this embodiment, including the dispensing nozzle assembly (inner plug 10, glass bead 20, one-way valve 30, dispensing nozzle 40, outer sleeve 50), middle cover 60, and electronic tag 90, is the same as in Embodiment 1, and will not be repeated here. The main differences between this embodiment and Embodiment 1 are: (1) the chip 94 protrudes from the lower surface of the substrate 92; (2) the specific implementation of the anti-rotation structure between the inner cover 70 and the dispensing nozzle 40; and (3) the specific structure of the destructive part on the inner cover 70 and the outer cover 80. Among them, the destructive part is a detailed solution of the alternative form disclosed in Embodiment 1, which is "the destructive part can be one or more protrusions that strike the chip like a hammer when rotating". It is provided in the anti-cavity groove 80a along the opening rotation direction of the outer cover ( Figure 18a The protruding structure on the rear side (in the direction indicated by arrow F) applies forces to the chip 94 in multiple directions simultaneously. In this embodiment, the surfaces of the protruding structure (including the first protrusion 84 and the second protrusion 86 described below) on the inner top surface of the outer cover 80 that apply forces to the chip 94 or serve as guides or limiters are collectively referred to as the main working surfaces, and the surfaces on the inner cover 70 that cooperate with the main working surfaces are collectively referred to as the secondary working surfaces.

[0119] Reference Figure 10-17On the top surface of the fixing body 72 of the inner cover 70, opposite to the chip 94, there is a receiving groove 76. The receiving groove 76 has a side opening 76a that extends to the outer peripheral surface 72a of the fixing body 72. The receiving groove 76 facilitates quick and accurate positioning when fixing the electronic tag 90. Through the positioning structure between the outer cover 80 and the inner cover 70, the clearance groove 80a on the outer cover 80 is aligned with the receiving groove 76 on the inner cover 70. Thus, when attaching and fixing the electronic tag, the chip 94 is aligned with the receiving groove 76, thereby achieving alignment between the chip 94 and the clearance groove 80a. On the other hand, there is a gap between the bottom surface of the chip 94 and the bottom surface of the receiving groove 76. This gap provides double protection for the chip 94 during the assembly of the outer cover 80, preventing the outer cover 80 from crushing the chip 94 during assembly.

[0120] The electronic tag 90 includes a substrate 92 and a chip 94 fixed to the substrate 92. As an example, the substrate 92 has a circular substrate body and a tail 92a extending radially outward from the edge of the substrate body. The substrate body is adhered and fixed to the top surface of the fastener body 72 of the inner cover 70. The chip 94 protrudes from the lower surface of the substrate 92, with a portion of the chip 94 received in a receiving groove 76 and another portion extending from a side opening 76a beyond the outer peripheral surface 72a, forming a protrusion 94a. The tail 92a is bent downwards, and its end ultimately extends and adheres to the outer peripheral surface of the middle cover 60.

[0121] A limiting protrusion 78 is provided on the front side of the side opening 76a along the rotational direction of the outer cover opening. The limiting protrusion 78 has a rear side surface along the rotational direction of the outer cover opening. This rear side surface constitutes a first secondary working surface 78a that mates with the first main working surface 84b described below. It is used to mate with the first main working surface 84b during the opening process to apply compressive stress in the rotational direction to the protruding portion 94a of the chip 94 and the base 92 covering the protruding portion 94a. Furthermore, since the receiving groove 76 is opened on the top surface of the inner cover 70 fixing body 72, and in the actual assembly process, the top surface of the inner cover 70 is usually facing down and away from the operator, it is difficult to be directly observed. It is difficult to accurately insert the chip 94 by simply looking at the outline of the receiving groove 76 with the naked eye. In this regard, the limiting protrusion 78 protrudes outward from the outer peripheral surface 72a of the inner cover 70 (refer to...). Figure 3 , Figure 4Regardless of the orientation of the top surface of the inner cover 70, the operator can directly observe or touch the limiting protrusion 78 from the side of the inner cover 70. Using the position of the limiting protrusion 78 as a reference, the operator can indirectly determine the orientation of the receiving groove 76 and the side opening 76a, assisting in accurately guiding the chip 94 into the predetermined position within the receiving groove 76. In other words, while the limiting protrusion 78 serves as a carrier for the first working surface and participates in the destruction of the chip 94, it also functions as a visual positioning indicator during the assembly stage, further reducing the risk of chip 94 assembly deviation or even damage due to the location of the receiving groove 76 not being easily visible.

[0122] Reference Figure 15 , 16 A first protrusion 84 is provided on the inner top surface of the outer cover 80, located behind the clearance groove 80a in the outer cover opening rotation direction. The first protrusion 84 is radially located outside the side opening 76a of the inner cover 70. The first protrusion 84 has a second main working surface 84a facing the inner cover 70. The second main working surface 84a is an inclined surface, and the height of the inclined surface from the inner top surface of the outer cover 80 gradually increases in the opposite direction of the outer cover opening rotation direction. That is, the further back the position is in the rotation direction, the more the second main working surface 84a protrudes relative to the inner cover 70. Correspondingly, the bottom surface of the receiving groove 76 forms a supporting surface that cooperates with the second main working surface 84a. The second main working surface 84a cooperates with the supporting surface to apply an axial compressive force to the protruding portion 94a of the chip 94 and the base 92 covering the protruding portion 94a. In the assembled state, the second main working surface 84a is located behind the chip 94 in the receiving groove 76 in the outer cover opening rotation direction. When the bottle cap is opened, the second main working surface 84a rotates from its original position behind the clearance groove 80a with the outer cap 80 and gradually moves above the position of the chip 94. As the height of the inclined surface increases along the rotation direction, the distance between the second main working surface 84a and the bottom surface of the receiving groove 76 gradually decreases with rotation. The downward pressure transmitted to the chip 94 through the substrate 92 gradually increases with the increase of the rotation angle. Even if the chip 94 has deviations in actual thickness or installation height due to processing or assembly tolerances, the second main working surface 84a can compensate for the deviations through the continuously increasing downward pressure, ensuring that the compressive stress is reliably transmitted to the chip 94 through the substrate 92, thereby improving the success rate of destruction.

[0123] The inner side 84e of the first protrusion 84 intersects with the second main working surface 84a to form a cutting edge 84c. When the bottle cap is opened, the cutting edge 84c rotates synchronously with the first protrusion 84, passing along the outer peripheral surface 72a, with a small gap between them. The outer peripheral surface 72a remains stationary because the main body 72 of the fixing member is stationary, forming a fixed support reference surface. The cutting edge 84c then forms a moving edge that rotates with the outer cap 80. The relative movement of the two together forms a shearing action on the protruding part 94a of the chip 94 and the base 92 covering the protruding part 94a.

[0124] The first protrusion 84 has a boss portion 84g protruding from the second main working surface 84a, and a first main working surface 84b is formed on the boss portion 84g on the front side of the first protrusion 84 along the opening rotation direction of the outer cap. The first main working surface 84b is an inclined surface, and the distance between the first main working surface 84b and the center of the inner cap 70 gradually increases along the opening rotation direction of the outer cap, that is, the inclined surface opens radially outward along the opening rotation direction of the outer cap; correspondingly, the distance between the first main working surface 84b and the rear side of the limiting protrusion 78, which is the first secondary working surface 78a, along the opening rotation direction of the outer cap gradually decreases from the inside to the outside along the radial direction of the inner cap 70. When the cap is opened, the first main working surface 84b rotates with the outer cap 80 and gradually turns to the angular position where the limiting protrusion 78 is located; during this rotation, the angular range of the first main working surface 84b and the first secondary working surface 78a in the opening rotation direction of the outer cap overlaps (see Figure 18b , 18c The overlapping area at this angle constitutes the extrusion section, which applies compressive stress in the direction of rotation to the protrusion 94a of the chip 94 and the substrate 92 covering the protrusion 94a. At the same time, the cutting blade 84c rotates synchronously with the first protrusion 84, generating a shearing motion between the protrusion 94a of the chip 94 and the substrate 92 covering the protrusion 94a.

[0125] The boss portion 84g is also provided with a third main working surface 84f. The third main working surface 84f is located behind the first main working surface 84b along the outer cover opening rotation direction and faces the center of the inner top surface of the outer cover 80. The front end of the third main working surface 84f along the outer cover opening rotation direction is connected to the rear end of the first main working surface 84b along the outer cover opening rotation direction, and both the third main working surface 84f and the first main working surface 84b are connected to the second main working surface 84a. During the opening rotation process, the third main working surface 84f and the side wall of the receiving groove 76 relative to the side opening 76a apply radial compressive stress to the chip and the substrate covering the chip.

[0126] A second protrusion 86 is provided radially inside the first protrusion 84. The second protrusion 86 has a fourth main working surface 86a, which is located radially inside the second main working surface 84a, facing the top surface of the inner cover 70, and is planar. When the chip 94 of the electronic tag 90 is misaligned and closer to the center of the inner cover 70, and is not inserted into the receiving groove 76, the second main working surface 84a may not be able to fully contact the substrate 92 at that position. In this case, the fourth main working surface 86a of the second protrusion 86 cooperates with the top surface of the fixing body 72, which can apply compressive stress to the chip 94 and the substrate 92 covering the chip 94, crushing the chip 94, thereby improving the fault tolerance of this embodiment for assembly deviations.

[0127] The second main working surface 84a of the first protrusion 84 is connected to the bottom surface of the clearance groove 80a by a first guide slope 84d, and the fourth main working surface 86a of the second protrusion 86 is connected to the bottom surface of the clearance groove 80a by a second guide slope 86b. The first guide slope 84d and the second guide slope 86b guide the substrate 92 covering the chip 94, so that when the outer cover 80 rotates, the chip 94 (along with the substrate 92 covering it) can be smoothly guided into the working position between the first main working surface 84b and the second main working surface 84a, avoiding the chip 94 from deviating from the predetermined position due to assembly tolerances and not being properly captured by the working surface, thus affecting the destructive effect.

[0128] Furthermore, a third protrusion 88 may be provided on the inner top surface of the outer cover 80, located in front of the clearance groove 80a along the opening rotation direction of the outer cover. In the assembled state, the third protrusion 88 is located in front of the limiting protrusion 78 along the opening rotation direction of the outer cover, and cooperates with the limiting protrusion 78 to restrict the outer cover 80 from rotating in the opposite direction of the opening rotation direction relative to the inner cover 70.

[0129] In this embodiment, the anti-rotation structure between the inner cover 70 and the spout 40 includes multiple insertion holes 42b and 42c on the top surface of the spout 40, and multiple insertion posts 75 and 77 on the bottom of the inner cover 70. The insertion holes 42b and 42c are inserted into the insertion posts 75 and 77 in a one-to-one correspondence to achieve the anti-rotation function. The positions of the insertion holes and insertion posts can also be interchanged, that is, the insertion holes are located on the inner cover 70, and the insertion posts are located on the spout 40.

[0130] In the assembled state, the pins 75 and 77 are tightly inserted into their corresponding holes 42b and 42c. Due to the tight fit, when the user attempts to unscrew the outer cap 80, the inner cap 70 is prevented from rotating due to the locking mechanism between it and the spout 40. This forces a relative rotation of the outer cap 80 relative to the inner cap 70 during the initial opening phase, thereby driving the chip to break. To prevent misalignment of the holes and pins during assembly, the pins include a large-diameter pin 77 and a small-diameter pin 75, with the outer diameter of the large-diameter pin 77 being larger than that of the small-diameter pin 75. Correspondingly, the holes include a large-diameter hole 42c and a small-diameter hole 42b, with the diameter of the large-diameter hole 42c being larger than that of the small-diameter hole 42b.

[0131] The assembly method in this embodiment is basically the same as in Embodiment 1, except for the assembly method of the electronic tag 90: After assembling the inner cover 70, the chip 94 of the electronic tag 90 is aligned with the receiving groove 76 and placed in, so that part of the chip 94 protrudes from the side opening 76a. The electronic tag 90 is fixed to the top surface of the inner cover 70 by adhesive. Then, the tail 92a of the base 92 is bent downward so that it covers the part of the chip 94 received in the receiving groove 76 and the protruding part 94a in sequence, and the end of the tail 92a is attached and fixed to the outer peripheral surface of the middle cover 60. Then, the outer cover 80 is assembled. When assembling the outer cover 80, the first protrusion 84 and the second protrusion 86 should be positioned at the rear side of the clearance groove 80a along the opening and rotation direction of the outer cover, and then the outer cover 80 should be pressed down axially so that the locking protrusion 82 on the outer cover 80 is engaged in the locking groove 62 on the middle cover 60.

[0132] The activation and anti-counterfeiting implementation process of this embodiment is as follows (refer to...) Figure 18a , 18b 18c):

[0133] 1. Initial state ( Figure 18a ): The bottle cap is screwed on the bottle mouth, the anti-cavity groove 80a of the outer cap 80 is precisely aligned with the receiving groove 76 of the inner cap 70 and the chip 94 inside it, the first protrusion 84 and the second protrusion 86 are both located outside the range of the anti-cavity groove 80a, and a safe gap is maintained between them and the substrate 92 covering the chip 94, so the chip 94 is in a safe state.

[0134] 2. Startup process ( Figure 18b When the user rotates the outer cover 80 in the opening direction, the middle cover 60 rotates synchronously with the outer cover 80. Due to the plug-in anti-rotation structure of the insertion hole and post between the inner cover 70 and the spout 40, the inner cover 70 and the electronic tag 90 and chip 94 fixed on it remain stationary, while the middle cover 60 and the outer cover 80 fixed to it begin to rotate relative to the inner cover 70. The first protrusion 84 then turns to the original position of the clearance groove 80a, and the second main working surface 84a begins to contact the base 92 and applies gradually increasing downward pressure through it; at the same time, the first main working surface 84b gradually approaches the rear side of the limiting protrusion 78, applying compressive stress in the rotational direction to the protruding part 94a of the chip 94 and the base 92 covering the protruding part 94a. At the same time, the second main working surface 84a cooperates with the bottom surface of the receiving groove, applying axial compressive stress to the protruding part and the base covering the protruding part. When the chip rotates to the third main working surface 84f position, the third main working surface 84f, in conjunction with the sidewall of the receiving groove 76 opposite to the side opening 76a, applies radial compressive stress to the chip and the substrate covering the chip. The cutting blade 84c exerts a shearing effect on the substrate 92 covering the protrusion 94a and the protrusion 94a together. During this stage, the chip 94 is partially crushed and broken, and as the middle cover 60 continues to rotate, the tail 92a is gradually torn off.

[0135] 3. Start and end ( Figure 18c As the outer cap 80 continues to rotate, the second main working surface 84a completely passes the location of the chip 94. Under the combined action of axial compressive stress, rotational compressive stress, and shear force transmitted through the substrate 92, the chip 94 is completely crushed, cut off, and broken, and its internal circuit structure is irreversibly physically destroyed. The broken chip 94 remains adhered and fixed to the substrate 92. Subsequently, as the middle cap 60 continues to rotate and rises along the internal thread 61, the insert at the bottom of the inner cap 70 gradually disengages from the corresponding insertion hole on the spout 40, the anti-rotation structure is released, and the outer cap assembly is unscrewed from the bottle opening as a whole, completing the opening action.

[0136] Compared with Embodiment 1, this embodiment has the following advantages: First, by applying axial compressive stress, rotational compressive stress, and shear force to the breaking part, both "crushing" and "cutting" destruction mechanisms are achieved in parallel and act on different parts of the chip 94 in different regions. Compared with the single crushing destruction method of Embodiment 1, the destruction is more thorough and complete. Second, the clearance groove 80a and the receiving groove 76 respectively set above the chip's relative position provide reliable protection for the chip, preventing damage during assembly and transportation. Third, the setting of the receiving groove 76, the limiting protrusion 78, and the third main working surface 84f improves the assembly accuracy of the electronic tag 90 and its tolerance for assembly deviations. Fourth, the anti-rotation structure of the insertion hole and the insertion post is more reliable than the anti-rotation structure of the convex / concave engagement, and by setting the insertion post and insertion hole with different hole diameters / outer diameters, assembly direction errors are effectively prevented. Batch testing statistics of bottle cap products using the structure of this embodiment show that the chip destruction success rate is significantly better than that of Embodiment 1.
