Description

Technical Field

[0001] This utility model relates to the field of anti-counterfeiting technology, specifically to an RFID tag, an RFID bottle cap that can be opened and damaged, and a bottle. Background Technology

[0002] RFID tags consist of a circuit, a substrate, and a chip. They are widely used in product packaging, especially in wine packaging. RFID tags are placed inside the bottle cap, allowing consumers to read the tags to determine the authenticity of the product or whether the packaging has been opened.

[0003] RFID tags are often attached to the top of the inner and middle caps with adhesive, such as the tag structure in CN219997587U. When the bottle is opened, the relative displacement between the inner and middle caps breaks the RFID tag. However, due to the limited volume of both the bottle cap and the middle cap, and the fact that the tag is mostly adhered to the inner cap with only a small portion adhering to the middle cap (typically only 2mm-4mm wide), the adhesion is often weak. When the outer cap causes relative displacement between the inner and middle caps, the tag cannot be destroyed. There are also designs that extend the RFID tag, such as the structure in CN208665920U, where part of the tag is attached to the base to facilitate destruction when the bottle is opened. However, with this type of tag, some residue remains at the bottle opening, and when pouring, the wine may come into contact with the tag and its pressure-sensitive adhesive, potentially posing a food safety risk. Utility Model Content

[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide an RFID tag, an RFID bottle cap that can be opened and damaged, and a bottle.

[0005] According to the present invention, an RFID tag is provided, the RFID tag includes an A area and a B area, the A area is partially used to connect with the surface of the inner cap of the bottle cap facing away from the opening end, and partially used to connect with the middle cap of the bottle cap on the same side, the B area is used to connect with the outer side of the middle cap. This utility model provides an RFID bottle cap that can be opened and destroyed. It includes an outer cap, a middle cap, an inner cap, and an RFID tag.

[0006] The outer cover is driven by a connector to rotate the middle cover synchronously. The connector may include a threaded structure, a serrated structure, or a bayonet structure.

[0007] The middle cover has a ring-shaped or barrel-shaped structure.

[0008] The middle cover is connected to the inner cover via a sliding component and a locking component, so that after the middle cover rotates to a preset position, it drives the inner cover to rotate.

[0009] The sliding component includes a retaining strip provided on the inner side of the middle cover, and the locking component includes a sliding groove provided on the outer side of the inner cover. The retaining strip is slidably connected in the sliding groove. When the retaining strip moves to the end point of the sliding groove, the middle cover, which continues to rotate, drives the inner cover to rotate.

[0010] The central axis of the middle cover coincides with the central axis of the inner cover.

[0011] The height of area B of the RFID tag in the axial direction is H1, and the height of the middle cover in the axial direction is H. The value range of H1 is 0 < H1 ≤ H.

[0012] The A area is partially connected to the side of the inner cover opposite to the opening end, and partially connected to the middle cover on the same side.

[0013] The B area is connected to the outer side of the middle cover, and the outer side of the middle cover and the inner side of the outer cover clamp the B area.

[0014] The axial force between the middle cover and the outer cover is greater than the axial force between the middle cover and the inner cover.

[0015] The circuitry of the RFID tag may be entirely located in area A, or partially located in area A and partially located in area B. Area A has cuts corresponding to the seam between the inner cover and the middle cover.

[0016] Preferably, area B is provided with a cut.

[0017] One end of the incision is connected to the edge of region B away from region A, and the other end points to region A or extends into the interior of region A. The incision consists of one or more incisions.

[0018] The inner cover is connected to a protective cover on the side opposite to the opening. The protective cover has an opening that allows RFID tags to pass through. The RFID tags are partially located inside the protective cover and partially located outside the protective cover.

[0019] Part of area A is located inside the protective cover, while area B and part of area A are located outside the protective cover.

[0020] Preferably, the cut is connected to the circuit portion of the RFID tag without affecting the original state of the circuit.

[0021] When there are multiple incisions, the spacing between two adjacent incisions or the spacing between the edge of region B and adjacent incisions may be equal or unequal. The length of each incision may be equal or unequal.

[0022] The outer side of the middle cover is provided with serrations, and the inner side of the outer cover is provided with serrations that engage with the middle cover. The B area is clamped between the serrations of the middle cover and the outer cover.

[0023] Preferably, the middle cover is divided into a middle cover body and a sleeve along the axial direction. The middle cover body is sleeved on the end of the inner cover away from the opening end, and the sleeve is sleeved on the outer peripheral surface of the inner cover near the opening end.

[0024] The outer cover is driven by a connector to rotate the middle cover body synchronously. The middle cover body is connected to the sleeve through a locking component, so that the middle cover drives the sleeve to rotate.

[0025] The sleeve is connected to the outer side of the inner cover through a sliding component and a locking component, so that after the sleeve rotates to a preset position, it drives the inner cover to rotate.

[0026] Preferably, the RFID tag is a high-frequency RFID tag with TT function.

[0027] The B area is connected to the outer side of the middle cover body and the outer side of the sleeve, or only to the outer side of the middle cover body.

[0028] When the B area is connected to the outer side of the middle cover body and the outer side of the sleeve, the coil portion of the high-frequency RFID containing the TT function is at least partially located in the B area, and the TT portion is at least partially located on the surface of the inner cover facing away from the opening end.

[0029] The RFID tag is a high-frequency RFID tag with TT function, and the coil portion of the RFID tag with TT function is located on the surface of the middle cover body facing away from the opening end of the inner cover.

[0030] The axial bonding force between the middle cover body and the outer cover, and the axial bonding force between the sleeve and the inner cover are both greater than the axial bonding force between the middle cover body and the sleeve. When the B area is connected to the outer side of the middle cover body and the outer side of the sleeve, the axial bonding force between the middle cover body and the outer cover and the axial bonding force between the sleeve and the inner cover are both greater than the sum of the axial bonding force between the middle cover body and the sleeve and the force required for the B area to break.

[0031] A bottle includes a bottle body and an openable RFID cap, the openable RFID cap being attached to the bottle opening of the bottle body.

[0032] Compared with the prior art, the present invention has the following beneficial effects: This invention provides an RFID bottle cap and bottle that can be opened and destroyed. Because area B is adhered to the outside of the inner cap, the bonding area between the tag and the inner cap is increased. Furthermore, area B is clamped between the sides of the inner and outer caps. Even if the pressure-sensitive adhesive of the tag decreases due to temperature, and the outer cap causes relative displacement between the inner and outer caps, the RFID tag can still be destroyed. In addition, the tag remains between the inner, middle, and outer caps, and the height of area B is less than the height of the inner cap. After opening the bottle cap, the tag will not remain on the cap base and will not come into contact with the liquid, thus avoiding potential contamination. Attached Figure Description

[0035] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0036] Example 1 like Figure 1 As shown, an RFID bottle cap that can be opened and damaged includes: an outer cap 1, a middle cap 2, an inner cap 3, and an RFID tag 4. The middle cap 2 is connected to the top surface of the inner cap 3 in a ring structure. The outer cap 1 is fitted over the middle cap 2 and the inner cap 3. The outer cap 1, the middle cap 2, and the inner cap 3 are arranged on the same central axis.

[0037] The outer cover 1 is driven by a connector to rotate the middle cover 2 synchronously. The connector can be a combination of threaded structure, sawtooth structure or bayonet structure to achieve synchronous rotation of the outer cover 1 and the middle cover 2.

[0038] The middle cover 2 is connected to the inner cover via a sliding component and a locking component. After the middle cover 2 rotates to a preset position, it drives the inner cover 3 to rotate. The sliding component can be a retaining strip provided on the inner side of the middle cover 2, and the locking component includes a sliding groove provided on the outer side of the inner cover 3. The retaining strip is slidably connected in the sliding groove. When the retaining strip moves to the end point of the sliding groove, the rotating middle cover 2 drives the inner cover 3 to rotate.

[0039] The RFID tag 4 includes area A 401 and area B 402. Area A 401 is partially connected to the side of the inner cover 3 facing away from the opening, and partially connected to the middle cover 2 on the same side. Area B is connected to the outer side of the middle cover 2. The connection method can be pressure-sensitive adhesive bonding, which is not limited in this invention. The axial height of area B 402 is H1, and the axial height of the middle cover 2 is H. The value of H1 is in the range of 0 < H1 ≤ H. The outer side of the middle cover 2 and the inner side of the outer cover 1 can clamp area B, preventing area B from separating from the middle cover 2 due to its small connection area.

[0040] The circuitry of the RFID tag is entirely located in area A 401, or partially in area A 401 and partially in area B 402. To ensure area B 402 fits snugly against the outer surface of the middle cover 2, a cut 403 is provided in area B 402. One end of the cut 403 connects to the edge of area B 402 away from area A 401, and the other end points towards area A 401 or extends into the interior of area A 401. There can be one or multiple cuts 403. These cuts 403 can connect to the circuitry of the RFID tag 4 without affecting the original state of the circuitry, allowing the circuitry of the RFID tag 4 to be easily torn off during the opening process. Simultaneously, if... Figure 8As shown, area A 401 has a cut 407 at the seam between the inner cover 3 and the middle cover 2, so that area A 401 can be torn along the cut 407 during the relative rotation of the inner cover 3 and the middle cover 2.

[0041] When there are multiple incisions 403, the spacing between adjacent incisions 403 or the spacing between incision 403 and the left and right edges of area B 402 can be equal or unequal. The length of each incision 403 can be equal or unequal.

[0042] Example 2 like Figure 2 As shown, an RFID bottle cap that can be opened and damaged includes: an outer cap 1, a middle cap 2, an inner cap 3, and an RFID tag 4. The middle cap 2 has a barrel-shaped structure connected to the top surface of the inner cap 3. The outer cap 1 is fitted over the middle cap 2 and the inner cap 3. The outer cap 1, middle cap 2, and inner cap 3 are arranged along the same central axis. The bottom of the barrel-shaped structure is not completely closed; this part is located at the top of the inner cap 3, making the barrel-shaped structure flush with the top of the inner cap 3 to facilitate the adhesion of the RFID tag 4.

[0043] The outer cover 1 is driven by a connector to rotate the middle cover 2 synchronously. The connector can be a combination of threaded structure, sawtooth structure or bayonet structure to achieve synchronous rotation of the outer cover 1 and the middle cover 2.

[0044] The middle cover 2 is connected to the inner cover via a sliding component and a locking component, so that after the middle cover 2 rotates to a preset position, it drives the inner cover 3 to rotate. The sliding component can be a retaining strip provided on the inner side of the middle cover 2, and the locking component includes a sliding groove provided on the outer side of the inner cover 3. The retaining strip is slidably connected in the sliding groove. When the retaining strip moves to the end point of the sliding groove, the middle cover 2, which continues to rotate, drives the inner cover 3 to rotate.

[0045] The RFID tag 4 includes area A 401 and area B 402. Area A 401 is partially connected to the side of the inner cover 3 facing away from the opening, and partially connected to the middle cover 2 on the same side. Area B is connected to the outer side of the middle cover 2. The connection method can be pressure-sensitive adhesive bonding, which is not limited in this invention. The axial height of area B 402 is H1, and the axial height of the middle cover 2 is H. The value of H1 is in the range of 0 < H1 ≤ H. The outer side of the middle cover 2 and the inner side of the outer cover 1 can clamp area B, preventing area B from separating from the middle cover 2 due to its small connection area.

[0046] The circuitry of the RFID tag is entirely located in area A 401, or partially in area A 401 and partially in area B 402. To ensure that area B 402 fits snugly against the outer surface of the middle cover 2, a cut 403 is provided in area B 402. One end of the cut 403 connects to the edge of area B 402 away from area A 401, and the other end points towards area A 401 or extends into the interior of area A 401. There can be one or multiple cuts 403. These cuts 403 can connect to the circuitry of the RFID tag 4 without affecting the original state of the circuitry, allowing the circuitry of the RFID tag 4 to be easily torn off during the opening process.

[0047] When there are multiple incisions 403, the spacing between adjacent incisions 403 or the spacing between incision 403 and the left and right edges of area B 402 can be equal or unequal. The length of each incision 403 can be equal or unequal.

[0048] Example 3 like Figure 3 As shown, an RFID bottle cap that can be opened and damaged includes: an outer cap 1, a middle cap 2, an inner cap 3, and an RFID tag 4. The middle cap 2 has a barrel-shaped structure connected to the top surface of the inner cap 3. The outer cap 1 is fitted over the middle cap 2 and the inner cap 3. The outer cap 1, middle cap 2, and inner cap 3 are arranged along the same central axis. The bottom of the barrel-shaped structure is fully open, with the same size as the opening of the barrel. This part is located at the top of the inner cap 3, making the barrel-shaped structure flush with the top of the inner cap 3 to facilitate the adhesion of the RFID tag 4.

[0049] The outer cover 1 is driven by a connector to rotate the middle cover 2 synchronously. The connector can be a combination of threaded structure, sawtooth structure or bayonet structure to achieve synchronous rotation of the outer cover 1 and the middle cover 2.

[0050] The middle cover 2 is connected to the inner cover via a sliding component and a locking component, so that after the middle cover 2 rotates to a preset position, it drives the inner cover 3 to rotate. The sliding component can be a retaining strip provided on the inner side of the middle cover 2, and the locking component includes a sliding groove provided on the outer side of the inner cover 3. The retaining strip is slidably connected in the sliding groove. When the retaining strip moves to the end point of the sliding groove, the middle cover 2, which continues to rotate, drives the inner cover 3 to rotate.

[0051] The RFID tag 4 includes area A 401 and area B 402. Area A 401 is partially connected to the side of the inner cover 3 facing away from the opening, and partially connected to the middle cover 2 on the same side. Area B is connected to the outer side of the middle cover 2. The connection method can be pressure-sensitive adhesive bonding, which is not limited in this invention. The axial height of area B 402 is H1, and the axial height of the middle cover 2 is H. The value of H1 is in the range of 0 < H1 ≤ H. The outer side of the middle cover 2 and the inner side of the outer cover 1 can clamp area B, preventing area B from separating from the middle cover 2 due to its small connection area.

[0052] The circuitry of the RFID tag is entirely located in area A 401, or partially in area A 401 and partially in area B 402. To ensure that area B 402 fits snugly against the outer surface of the middle cover 2, a cut 403 is provided in area B 402. One end of the cut 403 connects to the edge of area B 402 away from area A 401, and the other end points towards area A 401 or extends into the interior of area A 401. There can be one or multiple cuts 403. These cuts 403 can connect to the circuitry of the RFID tag 4 without affecting the original state of the circuitry, allowing the circuitry of the RFID tag 4 to be easily torn off during the opening process.

[0053] When there are multiple incisions 403, the spacing between adjacent incisions 403 or the spacing between incision 403 and the left and right edges of area B 402 can be equal or unequal. The length of each incision 403 can be equal or unequal.

[0054] The working principles of the above three embodiments are as follows: like Figure 4 As shown, an RFID tag is placed inside the bottle cap. Area B 402 has a cutout. After bending, the two sides of area B 402 overlap and adhere to the side of the middle cap 2. Alternatively, area B 402 may not have a cutout, but after bending, it adheres to the side of the middle cap 2. Area B 402 is clamped between the side of the middle cap 2 and the side of the outer cap 1. Rotating the outer cap 1 causes the middle cap 2 to rotate via a connector. The middle cap 2 rotates at an angle relative to the inner cap 3 via a sliding component, while the inner cap 3 does not rotate.

[0055] Because the B area 403 of the label is clamped between the outer cap 1 and the middle cap 2, it rotates together with the outer cap 1 and the middle cap 2. Meanwhile, the A area 401 of the label is attached to the top of the inner cap 3. A relative displacement occurs between the A area 401 and the B area 402 of the label, or between the area of ​​the label A attached to the top of the inner cap 3 and the area of ​​the label A 401 attached to the top of the middle cap 2. This damages the RFID tag 4. If the outer cap 1 continues to rotate, the middle cap 2 will drive the inner cap 3 to rotate through the locking mechanism, thus completing the opening of the bottle and damaging the RFID tag at the same time. At this point, the tag is removed along with the bottle cap, eliminating the risk of contaminating the wine.

[0056] Dense serrations can be set on the outer side of the middle cover 2, and serrations can be set on the inner surface of the outer cover 1 to engage with the middle cover 2. The RFID tag 4 is pasted inside the bottle cap, and then the middle cover 2 and the outer cover 1 are combined. The outer cover 1 can engage with the middle cover 2. The B area 402 with the cut 403 is locked by the serrations between the outer cover 1 and the middle cover 2. The outer cover 1 can drive the middle cover 2 and the inner cover 3 to move relative to each other, which can easily destroy the RFID tag 4.

[0057] When the circuit portion of RFID tag 4 is located in area A 401 and part of it is located in area B 402, and the cut 403 starts from the lower edge of area B 402 and cuts into part of the circuit but does not cut off the circuit, pointing towards area A, RFID tag 4 is in good condition. RFID tag 4 is then pasted inside the bottle cap, and area B 402 is bent and pasted to the side of the middle cap 2. The portions on both sides of each cut 403 overlap and fit tightly against the side of the middle cap 2. The outer cap 1 and the middle cap 2 clamp area B 402. Rotating the outer cap 1 can destroy the circuit portion, that is, destroy RFID tag 4.

[0058] Example 4 like Figure 5 As shown, based on the above embodiment, a protective cover 301 can be further added. The protective cover 301 has an opening that allows the RFID tag 4 to pass through. Part of the RFID tag 4 is located inside the protective cover 301, and part is located outside the protective cover 301. Part of area A 401 is located inside the protective cover 301, and area B 402 and part of area A 401 are located outside the protective cover 301. Since part of the RFID tag is located inside the protective cover 301 and part of the tag is located outside the protective cover 301, even if the pressure-sensitive adhesive of the tag decreases due to temperature, causing relative displacement between the outer cover and the middle cover and the inner cover, the RFID tag can still be damaged.

[0059] like Figure 6 As shown, when the bottle is opened by rotating the cap, the outer cap 1 drives the middle cap 2 to rotate via the connector. The middle cap 2 then rotates at an angle to the inner cap 3 via the sliding component, thereby damaging the RFID tag 4. At this time, the inner cap 3 does not rotate. If the outer cap 1 is rotated further, the middle cap 2 drives the inner cap 3 to rotate via the locking component, thus completing the opening of the bottle and damaging the RFID tag at the same time. The tag is then removed along with the bottle cap, eliminating the risk of contaminating the wine.

[0060] When the outer cap 1 is forcibly pulled out, because the axial force between the middle cap 2 and the outer cap 1 is greater than the axial force between the middle cap 2 and the inner cap 3, the outer cap 1 pulls the middle cap 2 upwards, causing relative displacement between the top of the inner cap 3 and the top of the middle cap 2, thus damaging area A 401. Area A 401 corresponds to the coil portion of the RFID tag 4, so the RFID tag 4 completely loses its read / write function at this time, clearly indicating that the bottle cap (due to being forcibly pulled out) has been damaged.

[0061] Because a protective cover 301 is installed on the top of the inner cover, some RFID tags are located inside the protective cover 301 and some tags are located outside the protective cover 301. Even if the pressure-sensitive adhesive of the tag is reduced due to the temperature, and the outer cover causes relative displacement between the middle cover 2 and the inner cover 3, the RFID tag 4 can still be damaged.

[0062] Example 5 like Figure 7As shown, based on the aforementioned embodiment, the middle cover 2 is divided axially into a middle cover body 201 and a sleeve 202. The middle cover body 201 is fitted onto the end of the inner cover 3 away from the opening end, and the sleeve 202 is fitted onto the outer circumferential surface of the inner cover 3 near the opening end. The middle cover body 201 is connected to the sleeve 202 through a locking component, causing the middle cover body 201 to drive the sleeve 202 to rotate; the sleeve 202 is connected to the inner cover 3 through a sliding component and a locking component, causing the sleeve 202 to rotate to a preset position, thereby driving the inner cover 3 to rotate.

[0063] Area B 402 is connected to the outer side of the middle cover body 201 and the outer side of the sleeve 202, or only to the outer side of the middle cover body 201. The RFID tag 4 is a high-frequency RFID with TT function, where TT stands for Tag Tamper, i.e., a tag with an opening detection function or a bottle opening detection function. When area B 402 is connected to the outer side of the middle cover body 201 and the outer side of the sleeve 202, the coil portion 405 of the high-frequency RFID with TT function is at least partially located in area B, and the TT portion 406 is at least partially located on the surface of the inner cover 3 facing away from the opening end. The coil portion 405 of the high-frequency RFID with TT function is partially located on the surface of the middle cover body 201 facing away from the opening end of the inner cover 3.

[0064] like Figure 8 As shown, when the bottle cap is opened normally, the outer cap 1 drives the middle cap body 201. The middle cap body 201 drives the sleeve 202 through the locking component, causing the middle cap body 201 to rotate and the sleeve 202 to rotate. The sleeve 202 rotates relative to the inner cap 3 due to the sliding component. At this time, the A area 401 of the RFID tag 4 (corresponding to the TT part 406 in this embodiment) is torn due to the relative rotation between the top of the middle cap body 201 and the top of the inner cap 3, thus damaging the RFID tag 4. When the middle cap body 201 continues to drive the sleeve 202 to the locking component, the outer cap 1 drives the middle cap body 201, drives the sleeve 202, and drives the inner cap 3 to rotate, thereby opening the bottle cap. At this time, the coil part 405 is not damaged, and can still be read and written normally by the reading and writing device to the chip 404. The chip 404 recognizes that the TT part 406 has been damaged, indicating that the bottle cap has been opened.

[0065] like Figure 9As shown, when the outer cover 1 is forcibly pulled out, the axial bonding force between the middle cover body 201 and the outer cover 1, and the axial bonding force between the sleeve 202 and the inner cover 3 are both greater than the axial bonding force between the middle cover body 201 and the sleeve 202. The outer cover 1 pulls the middle cover body 201 upwards, while the sleeve 202 remains on the inner cover 3. The top of the inner cover 3 and the top of the middle cover body 201 experience relative displacement, and area A 401 is damaged (corresponding to TT portion 406 in this embodiment). When area B 402 connects to the outer surface of the middle cover body 201 and the outer surface of the sleeve 202, the axial bonding force between the middle cover body 201 and the outer cover 1, and the axial bonding force between the sleeve 202 and the inner cover 3 are both greater than the sum of the axial bonding force between the middle cover body 201 and the sleeve 202 and the force required to break area B 402. This achieves separation between the middle cover body 201 and the sleeve 202 after area B 402 breaks. The side of the middle cover body 201 and the side of the sleeve 202 are relatively displaced, and area B 402 (corresponding to the ring part 405 in this embodiment) is also damaged. At this time, the RFID tag 4 completely loses its reading and writing function, which can clearly indicate that the bottle cap (due to being forcibly pulled off) has been damaged.

[0066] Because a sleeve 202 is added to the outside of the inner cover 3, the main body 201 of the middle cover drives the sleeve 202 to rotate. After the sleeve 202 rotates to the preset position, it drives the inner cover 3 to rotate. This allows the RFID tag 4 to be torn in area A 401 when it is opened normally due to the relative displacement between the top of the middle cover 201 and the top of the inner cover 3. When the outer cover is forcibly pulled up, area B 402 is torn as the middle cover 201 separates from the sleeve 202. This achieves different damage modes when the cover is opened normally and when it is forcibly opened.

[0067] This invention relates to an RFID bottle cap that can be opened and damaged. In scenarios where anti-counterfeiting is required, such as wine bottles, the RFID bottle cap can be connected to the bottle opening, which can greatly increase the difficulty of preventing the reuse of normally opened bottle caps.

[0068] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
