Technical Field

[0001] The invention relates to an opening detection label and a container with the label.

[0002] This application claims priority based on Japanese Patent Application No. 2022-144591 filed in Japan on September 12, 2022, the contents of which are cited herein. Background Art

[0003] In recent years, counterfeit products have appeared in the field of premium wines. In particular, in the field of red wine, it is estimated that about 20% of the red wine sold worldwide is counterfeited. Regarding the replacement of red wine, the cap seal that is set on the red wine bottle and covers the cork is removed and the bottle is opened and replaced. In addition, in recent years, the following counterfeiting behaviors have been carried out in a way that does not damage the red wine bottle, cork, or cap seal:

[0004] That is, the wine bottle is improperly opened using a syringe or the like, a hole (injection hole) is made in the cork of the wine bottle, and the wine is replaced with counterfeit wine.

[0005] In order to detect improper opening of containers such as red wine bottles, Patent Document 1 discloses a device comprising: an IC chip; and a mesh-like wire, which is arranged on the surface opposite to the cover seal and is electrically connected to the IC chip. If the user punctures the plug to replace the contents, the wire is cut off, and the IC chip is used to detect the power cut of the wire to prove that the bottle has been opened.

[0006] Patent Document 1: Japanese Patent No. 6829690 Summary of the invention

[0007] However, the authentication device described in Patent Document 1 is a technology that determines that the seal is opened when the wiring provided in the cover seal is broken, and cannot distinguish whether the opened state is an improper opened state or a normal opened state in which the cover seal is originally peeled off.

[0008] The present invention has been made in consideration of such a situation, and an object thereof is to provide an opening detection label and a labeled container that can detect improper replacement of the contents of a container by opening a hole in a sealing portion provided at an opening.

[0009] In order to solve the above problems, the present invention proposes the following method.

[0010] The first embodiment of the present invention relates to an unsealing detection label which is installed on a container having a sealing portion that seals an upper opening, wherein the label comprises: an insulating substrate; an electrode having a first electrode disposed on the surface side of the substrate and a second electrode disposed on the back side of the substrate and opposite to the first electrode, and arranged on the upper side of the sealing portion; an antenna portion capable of performing contactless communication with an external instrument; and an IC chip electrically connected to the electrode and the antenna portion, measuring the capacitance formed between the first electrode and the second electrode, wherein the IC chip performs contactless communication with the external instrument via the antenna portion, and sends the capacitance measured by the IC chip to the external instrument.

[0011] Effects of the Invention

[0025] (First Embodiment)

[0026] Reference Figures 1 to 8B The first embodiment of the present invention is described. In the embodiments and modifications described below, the same reference numerals are used for structures corresponding to each other, and descriptions of repeated parts are sometimes omitted. In the following description, expressions such as "parallel", "orthogonal", "center", "coaxial", etc., which indicate relative or absolute configurations, not only strictly indicate such configurations, but also indicate a state of relative displacement at an angle or distance with a tolerance, a degree that the same function can be obtained.

[0027] Figure 1 It is a perspective view showing a labeled container 10 according to the first embodiment of the present invention. Figure 2 It is a front view showing the structure of the opening detection label 1 of the labeled container 10 .

[0028] In this embodiment, the labeled container 10 is placed with the wine bottle 2 as the container in contact with the ground. However, the labeled container 10 may be placed horizontally during storage in a wine rack or during transportation in a wooden box or the like.

[0029] In the following description of the labeled container 10 , the direction along the long side of the wine bottle 2 placed on the ground is defined as the up-down direction A, the upper side is defined as the upper side A1 , and the lower side as the ground side is defined as the lower side A2 .

[0030] The labeled container 10 comprises: a red wine bottle 2 ; and a seal 100 with an IC tag, which includes an opening detection label 1 .

[0031] [Red wine bottle (container) 2]

[0032] The wine bottle (container) 2 can utilize a wine bottle of a generally known size and shape. The wine bottle 2 has a body 20, a bottleneck 21, and an opening 22. The body 20 has a receiving portion 20s that can receive liquid contents. The bottleneck 21 extends along the vertical direction A on the upper side A1 of the body 20, and has an outer diameter smaller than the body 20. The label paper 101 is mounted on the side 21a of the bottleneck 21. The IC chip 5 and the antenna part 6 described later are mounted on the label paper 101. The opening 22 is formed on the upper side A1 of the bottleneck 21.

[0033] The wine bottle 2 has a central axis O1. The wine bottle 2 is formed by, for example, connecting a body 20, a neck 21, and an opening 22 along the central axis O1 from the lower side A2 to the upper side A1 in the vertical direction A. In the unopened state, the wine bottle 2 is provided with a cork (sealing part) 23 at the opening 22 (see Figure 5 ) and the opening 22 is sealed with the cork 23. When the wine bottle 2 is in an unopened state, a cover (cap seal) 24 is installed in a manner that covers the opening 22 and the neck 21 from the upper side A1.

[0034] The perforations 24a for opening are provided in the cover 24 along the circumferential direction R of the bottle neck 21. One side of the perforations 24a in the circumferential direction R is formed into a "U" shape without perforations. The user can hold the opening portion 24b formed by the perforations 24a and open the cover from the other side in the circumferential direction R toward one side.

[0035] [Seal with IC tag 100]

[0036] like Figure 1 As shown, the seal 100 with IC tag is attached to the bottle neck 21 by adhesive or the like. In this embodiment, the seal 100 with IC tag is provided between the opening 22 of the wine bottle 2 and the bottle neck 21 and the cover 24, but may also be provided on the outer surface of the cover 24.

[0037] The seal 100 with an IC tag includes: an opening detection label 1 ; and a label upper paper 101 which serves as a support body of the seal 100 with an IC tag.

[0038] [Opening detection label 1]

[0039] The unsealing detection label 1 is provided on a red wine bottle 2. The unsealing detection label 1 is, for example, a label that performs contactless communication with a contactless external device such as a smartphone or a reader / writer that supports UHF or NFC, and can detect that the red wine bottle 2 is unsealed improperly. The unsealing detection label 1 includes a substrate 3, a front side connection portion 11, a back side connection portion 12, an electrode 4, an IC chip 5, and an antenna portion 6.

[0040] [Base material 3]

[0041] The substrate 3 is an insulating sheet-like substrate. Figure 2 As shown, the substrate 3 is installed in the wine bottle 2 in such a manner that the opening 22 of the wine bottle 2 is covered and arranged on the cork 23 (see FIG. Figure 5 ) on the upper side A1 of the opening 22. In the present embodiment, the plate thickness direction of the substrate 3 is the same direction as the up-down direction A. Therefore, the surface side of the substrate 3 is the upper side A1, and the back side is the lower side A2. The substrate 3 is observed from the upper side A1 of the up-down direction A to be approximately the same size as the periphery 22a of the opening 22, and is formed in a circular shape with the central axis along the up-down direction A as the center. The central axis of the substrate 3 is the same as the central axis O1. The substrate 3 serves as a support for the electrode 4 described later. In addition, the substrate 3 can be formed integrally with the label paper 101 described later. In the subsequent description, the direction toward the central axis O1 is set as the inner circumference P1, and the opposite direction of the inner circumference P1 is set as the outer circumference P2.

[0042] In the present embodiment, the substrate 3 is formed by, for example, a PET substrate. However, the material of the substrate 3 is not particularly limited, and may be, for example, epoxy glass, a paper substrate, or a substrate composed of a plurality of materials. When a paper substrate is used, the environmental load can be further reduced. In addition, the substrate 3 may be transparent or opaque. When the substrate 3 is opaque, the needle detection portion 413 of the electrode 4 described later is hidden and the specific position cannot be known, so it is difficult for the user to avoid the needle detection portion 413 and insert the needle.

[0043] [Surface side connection portion 11]

[0044] like Figure 2 As shown, the front side connection part 11 electrically connects the IC chip 5 and the first electrode 41 described later. The front side connection part 11 is a wire extending from the base end part 11a connected to the IC chip 5 to the front end part 11b connected to the first electrode 41 (see Figure 3 ). In addition, Figure 1 As shown, the surface side connection part 11 extends across the unsealing part 24b of the cover 24. The surface side connection part 11 is attached to the cover 24, and the adhesion force is stronger than the tensile shear force of the surface side connection part 11. Therefore, if the unsealing part 24b is unsealed by the user, the surface side connection part 11 is disconnected.

[0045] [Back side connection portion 12]

[0046] like Figure 2As shown in FIG. 1 , the back side connection portion 12 electrically connects the IC chip 5 and the second electrode 42 described later. The back side connection portion 12 is a wire extending approximately parallel to the vertical direction A in a manner adjacent to the front side connection portion 11. The back side connection portion 12 extends from a base end portion 12a connected to the IC chip 5 to a front end portion 12b connected to the second electrode 42. Figure 1 As shown, the back side connection part 12, like the front side connection part 11, extends across the unsealing part 24b of the cover 24. The back side connection part 12 is attached to the cover 24, and its adhesive force is stronger than the tensile shear force of the front side connection part 11. Therefore, if the unsealing part 24b is unsealed by the user, the back side connection part 12 is disconnected.

[0047] [Electrode 4]

[0048] like Figure 2 As shown, the electrode 4 is provided on the surface and back side (upper side A1 and lower side A2) of the substrate 3. The electrode 4 is provided on the upper side A1 of the cork 23 similarly to the substrate 3. The electrode 4 has a detection part for detecting the unsealing when a tool such as an injection needle is inserted from the upper side A1 of the wine bottle 2 and the bottle is improperly unsealed. As for the electrode 4, as a manufacturing method, laser cutting of a metal plate or metal foil, punching, etching of a metal foil or metal layer, and arrangement of a metal wire can be exemplified. The electrode 4 has a first electrode 41 and a second electrode 42.

[0049] [First electrode 41]

[0050] Figure 3 1 is a diagram showing the structure of the opening detection label 1. Figure 2 In the figure, for convenience of explanation, the base material 3 is omitted, and the front side connection part 11 and the back side connection part 12 are shown in a changed shape.

[0051] The first electrode 41 is a linear electrode provided on the surface side of the substrate 3, that is, the upper side A1. The first electrode 41 is formed into a circle with the central axis O1 as the center by winding a conductive wire, and the outer diameter of the first electrode 41 is substantially the same as the outer diameter of the substrate 3 when viewed from the upper side A1 in the vertical direction A.

[0052] The first electrode 41 includes a needle detection portion 413 , a first peripheral electrode portion 414 , and a first electrode connection portion 410 .

[0053] The needle detection unit 413 detects the situation where the user punctures the cork 23 using a syringe needle or the like. Figure 3 As shown, the needle detection part 413 is a portion of the first electrode 41 where one conductive wire is not crossed and formed in a writing shape. In this embodiment, the wire width H1 of the needle detection part 413 (see Figure 4 ) are formed evenly.

[0054] The needle detection portion 413 is formed at least in the area overlapping with the opening portion 22 when viewed from the up-down direction A, and is formed closer to the inner circumferential side P1 than the peripheral edge 22a of the opening portion 22. The needle detection portion 413 is formed in a manner of being wound into a circular shape with more than or equal to two turns, forming a spiral shape. Specifically, the needle detection portion 413 is wound into a spiral shape from the base end 413b connected to the surface-side connection portion 11 toward the inner circumferential side P1 and toward one side of the circumference of the substrate 3. Here, the circumference of the substrate 3 is the same direction as the circumferential direction R. Then, the needle detection portion 413 turns back near the central axis O1, and is wound into a spiral shape toward the outer circumferential side P2 and toward the other side of the circumferential direction R, and the front end 413a is connected to the first peripheral electrode portion 414 via the first electrode connection portion 410. At this time, the needle detection portion 413 is formed in a writing shape in a manner in which one wire does not cross or branch.

[0055] Figure 4 Yes Figure 3 An enlarged view of region F is shown.

[0056] like Figure 4 As shown, for example, the width between two adjacent conductive wires of the needle detection unit 413 has a width H2. The line width H1 and the width H2 of the conductive wire of the needle detection unit 413 are each set to be less than or equal to 0.3 mm.

[0057] For example, when a needle is used to puncture the cork 23 of a wine bottle 2, the needle forms an injection hole 25 with a diameter H3 in the cork 23. When a needle with an outer dimension of 1 mm in diameter is used, the diameter H3 is about 1 mm. The width H1 and the width H2 are each set to be less than or equal to 0.3 mm, so that the wire of the needle detection unit 413 can be reliably disconnected.

[0058] In addition, the cork 23 usually has a length of about 30 mm from the uppermost portion of the opening 22 of the wine bottle 2 toward the bottom of the wine bottle 2. It is difficult for a user to puncture the cork 23 to a depth of 30 mm with a relatively thin injection needle having a diameter of 1 mm or less over the above length. Therefore, the width H1 and the width H2 are set to be less than or equal to 0.3 mm in advance, so that no matter where the user punctures the cork 23 at the opening 22 with the injection needle, the needle detection unit 413 can detect that the cork 23 has been punctured.

[0059] Regarding the thickness of injection needles, there are needle measurement standards. For example, as a standard for injection needles using stainless steel SUS316, there is a standard of 0.10±0.02mm to 2.70±0.03mm for the outer diameter. The inner diameter corresponding to the above standard is 0.03±0.02mm to 2.40±0.03mm. For example, a needle used for blood transfusion has an outer diameter of 1.20mm and an inner diameter of 0.94mm. If the thickness of the needle is thinner, the cross-sectional area decreases sharply.

[0060] For example, if the cross-sectional area of ​​the inner diameter of a needle with an outer diameter of 1.20 mm is set to 100%, the cross-sectional area is 76% when the outer diameter is 1.08 mm, 9% when the outer diameter is 0.51 mm, and 0.1% when the outer diameter is 0.10 mm. Therefore, a needle with an outer diameter of 1 mm or less is not strong enough to pierce the cork 23, and it is difficult to ensure the flow rate.

[0061] The first peripheral electrode portion 414 is an electrode that has approximately the same size and shape as the periphery 22a of the opening 22 of the wine bottle 2 when viewed from the upper side A1 in the up-down direction A, and is formed in an arc shape with the central axis O1 as the center. The first peripheral electrode portion 414 is designed not to be exposed from the periphery 22a to the outer peripheral side P2 when viewed from the up-down direction A. In addition, the first peripheral electrode portion 414 does not overlap with the opening 22 when viewed from the up-down direction A. The first peripheral electrode portion 414 has a through hole 415 in the center. The through hole 415 is the same size as the inner diameter of the opening 22. The arc-shaped first peripheral electrode portion 414 is provided with a gap 414p near the intersection with the surface-side connection portion 11. The surface-side connection portion 11 is electrically connected to the first peripheral electrode portion 414 without passing through the gap 414p, and the IC chip 5 provided on the outer peripheral side P2 of the first peripheral electrode portion 414 is electrically connected to the needle detection portion 413 provided on the inner peripheral side P1 of the first peripheral electrode portion 414. In addition, the size and shape of the first peripheral electrode portion 414 are not limited to the present embodiment, and when viewed from the upper side A1 in the up-down direction A, it may be exposed from the peripheral edge 22a to the outer peripheral side P2, or it may overlap with the opening 22.

[0062] The line width of the conductive wire of the first peripheral electrode portion 414 is larger (thicker) than the line width of the conductive wire of the needle detection portion 413. Therefore, when the conductive wire of the needle detection portion 413 is disconnected by the injection needle and electricity does not flow through the first peripheral electrode portion 414, the area of ​​the further accumulated capacitance disappears to a greater extent, which can increase the change in capacitance.

[0063] The first electrode connection part 410 electrically connects the needle detection part 413 and the first peripheral electrode part 414. The first electrode connection part 410 is not an indispensable structure, and the needle detection part 413 and the first peripheral electrode part 414 may be directly connected without being provided.

[0064] [Second electrode 42]

[0065] The second electrode 42 is an annular electrode centered on the central axis O1 provided on the back side of the substrate 3, that is, the lower side A2. The outer diameter of the second electrode 42 is substantially the same as the outer diameter of the first electrode 41 when viewed from the upper side A1 in the vertical direction A. The second electrode 42 has a second peripheral electrode portion 422. Substantially the same size means that the dimension in the vertical direction A and the dimension in the direction perpendicular to the vertical direction A are the same.

[0066] The second peripheral electrode portion 422 is an annular electrode having substantially the same size and shape as the first peripheral electrode portion 414 when viewed from the upper side A1 in the up-down direction A, and having a through hole 423 at the center. The second peripheral electrode portion 422 is opposite to the first peripheral electrode portion 414 across the substrate 3. The through hole 423 has the same size as the inner diameter of the opening 22. The second peripheral electrode portion 422 is electrically connected to the IC chip 5 using the back side connection portion 12.

[0067] Electrode 4 induces a high-frequency voltage to antenna unit 6 (described later) due to a high-frequency electromagnetic field generated by a transceiver circuit of a non-contact external device (not shown), whereby voltage is applied and capacitance is accumulated between first electrode 41 and second electrode 42 .

[0068] [IC chip 5]

[0069] The IC chip 5 is mounted on the side surface 21a of the bottleneck 21 and is connected to both the first electrode 41 and the second electrode 42. The IC chip 5 communicates with an external device via the antenna unit 6 to realize the wireless communication function of the opening detection label 1. Specifically, the IC chip 5 is supplied with power via the antenna unit 6. In addition, the IC chip 5 can perform wireless communication, obtain commands from an external device, and perform communication in response to the commands.

[0070] In the present embodiment, the IC chip 5 has a function of receiving a command from an external device and measuring the capacitance accumulated between the first electrode 41 and the second electrode 42. In addition, the IC chip 5 can transmit the measured capacitance to the external device through wireless communication.

[0071] In addition, the IC chip 5 can obtain a command from an external device, and can distinguish and detect the unsealed state based on the change in the capacitance accumulated between the first electrode 41 and the second electrode 42. Specifically, the IC chip 5 can distinguish the state where the lead wire of the needle detection unit 413 is disconnected and the capacitance is reduced, and the state where the front side connection unit 11 and the back side connection unit 12 are disconnected and electricity does not flow through the electrodes and the measured value of the capacitance is 0. The details of this function will be described later.

[0072] For example, the IC chip 5 can store information about the capacitance in the unopened state, so that when a command is obtained from an external instrument and the measured capacitance changes relative to the capacitance in the unopened state, the unopened state is detected. In addition, the IC chip 5 may not store information about the capacitance in the unopened state. In this case, the external instrument can store information about the capacitance in the unopened state in the application, so that when the capacitance obtained from the IC chip 5 through wireless communication changes, the unopened state is detected.

[0073] The IC chip 5 may have a function of further acquiring a command from an external device and measuring the disconnection or resistance value of the wire of the first electrode 41 or the second electrode 42. In this case, the IC chip 5 can detect the disconnection of the wire or measure the resistance value through wireless communication and transmit it to the external device.

[0074] In addition, the IC chip 5 can store information related to the content and identification information for the wine bottle 2 on which the IC chip 5 is installed. In this case, the IC chip 5 can send information related to the content and identification information to an external device. In addition, the IC chip 5 can add or update information using an external device. In addition, the configuration position of the IC chip 5 is not particularly limited, as long as it is configured at a distance separated from the opening 22 of the wine bottle 2.

[0075] [Antenna section 6]

[0076] The antenna unit 6 is mounted on the side surface 21a of the bottleneck 21. The antenna unit 6 is a ring-shaped conductor connected to the IC chip 5. The antenna unit 6 can use a currently known antenna, for example, an antenna length and antenna line width designed to correspond to the UHF band and the HF band. In addition, the configuration position of the antenna unit 6 is not particularly limited, as long as it is configured at a distance separated from the opening 22 of the red wine bottle 2.

[0077] The antenna unit 6 can perform contactless communication with contactless external devices such as a reader / writer, a mobile phone, etc. The IC chip 5 communicating with the external device using the antenna unit 6 can be supplied with power and receive a command from the external device and perform communication in response to the command.

[0078] In addition, in this embodiment, the base end and the front end of the antenna part 6 are connected by jumper wiring on the surface of the sign paper 101, but this is not particularly limited. The base end and the front end can also be caulked, a through hole can be formed, and a wiring circuit can be set on the back of the sign paper 101 to connect.

[0079] [Signage Paper 101]

[0080] The label paper 101 is a sheet of paper, such as Figure 1 or Figure 2As shown, the side surface 21a of the bottleneck 21 is formed into a rectangular shape with long sides and short sides facing each other. In this embodiment, the unsealing detection label 1 is set on the bottleneck 21 and the cover 24 (refer to Figure 1 ), but can also be set on the outer surface of the cover 24. Preferably, the label paper 101 is flexible so that it can be pasted along the curved side 21a of the bottleneck 21 of the red wine bottle 2. Figure 1 As shown, the label paper 101 is formed along the curved shape of the side 21a of the bottleneck 21, but may be formed along a tangent plane to a part of the side 21a of the bottleneck 21. In addition, the label paper 101 may be transparent or opaque.

[0081] The label paper 101 is attached to the wine bottle 2 by adhesive or the like. The label paper 101 may have an adhesive on the back side of the inner circumference P1, or the seal 100 with the IC tag may be attached to the wine bottle 2 by applying an adhesive on the surface of the outer circumference P2 of the label paper 101 or the side 21a of the bottleneck 21, and attaching the seal 100 with the IC tag there. In addition, the label paper 101 may not have an adhesive, but may be sandwiched between the bottleneck 21 and the cover 24 of the wine bottle 2. The label paper 101 is mounted with the IC chip 5 and the antenna part 6 of the unsealing detection label 1. However, the label paper 101 may further be mounted with the substrate 3 and the electrode 4. In this case, the upper part of the upper side A1 of the label paper 101 is attached to the upper side A1 of the wine bottle 2 in a bent manner so as to cover the opening 22 of the wine bottle 2. In addition, the label cover 101 may be formed integrally with the base material 3 .

[0082] (effect)

[0083] Next, the operation of the labeled container 10 will be described.

[0084] First, the labeled container 10 is formed such that the seal 100 with an IC tag is attached to the bottleneck 21 of the wine bottle 2 by adhesive or the like and then covered by the cover 24. In addition, the adhesive applied to the label upper paper 101 of the seal 100 with an IC tag can be provided on the bottleneck 21, the inner surface of the inner circumference side P1 or the outer surface of the outer circumference side P2 of the label upper paper 101, or can be provided on the cover 24 of the wine bottle 2. The base material 3 and the electrode 4 of the unsealing detection label 1 of the seal 100 with an IC tag are provided on the upper side A1 of the cork 23 in a manner covering the opening 22 of the wine bottle 2.

[0085] Next, the wine bottle 2 can be unsealed from the unopened state to take out the contents. The unsealing is divided into a state of improper opening using an injection needle (hereinafter referred to as an improper opening state) and a state of normal opening (hereinafter referred to as a normal opening state).

[0086] [Improperly opened state]

[0087] First, the operation of the labeled container 10 in the improperly opened state will be described.

[0088] Figure 5 1 is a diagram showing a state in which an injection hole 25 is formed in the wine bottle 2 of the labeled container 10. The user punctures the cork 23 with an injection needle and improperly replaces the wine as the content of the wine bottle 2. This state is referred to as an improperly opened state. At this time, the injection hole 25 is formed by puncturing the cork 23 with an injection needle or the like.

[0089] like Figure 5 As shown, the injection hole 25 causes the lead wire of the needle detection part 413 to be disconnected. As a result, the lead wire from the disconnected position of the needle detection part 413 to the front end 413a is no longer electrically connected to the IC chip 5. In addition, the first peripheral electrode part 414 connected to the front end 413a is also not electrically connected to the IC chip 5. Therefore, the area of ​​electrical connection between the needle detection part 413 and the first peripheral electrode part 414 is reduced, and the capacitance accumulated between the first electrode 41 and the second electrode 42 is smaller than that in the unsealed state where the lead wire of the needle detection part 413 is not disconnected.

[0090] However, the first electrode 41 and the second electrode 42 remain connected to the IC chip 5 , so the measured value of the capacitance does not become zero.

[0091] When a user brings an external device close to the opening detection label 1 provided on the side of the wine bottle 2 of the labeled container 10, the IC chip 5 of the opening detection label 1 communicates with the external device via the antenna unit 6. The IC chip 5 receives a command from the external device and measures the capacitance accumulated between the first electrode 41 and the second electrode 42.

[0092] For example, in the case where the IC chip 5 stores information about the capacitance in the unopened state, the capacitance measured by the IC chip 5 in the improperly unsealed state changes relative to the capacitance in the unopened state, and thus the unsealed state is detected. In addition, the capacitance measured by the IC chip 5 is smaller than the capacitance in the unopened state, and the measured value of the capacitance is not 0, so the IC chip 5 can be detected as an improperly unsealed state. In addition, the external instrument stores information about the capacitance in the unopened state in the application, so that the capacitance obtained from the IC chip 5 through wireless communication is smaller than the capacitance in the unopened state, and the measured value is not 0, so it can be detected as an improperly unsealed state.

[0093] [Normal opening status]

[0094] Next, the operation of the labeled container 10 in the normal unsealed state will be described.

[0095] Figure 6 The diagram shows a state where the wine bottle 2 of the labeled container 10 is opened from the perforated hole 24a of the cover 24. The user holds the opening portion 24b surrounded by the perforated hole 24a to open the cover 24. This state is referred to as a normal opening state.

[0096] If the unsealed portion 24b is unsealed by the user, the front side connection portion 11 connecting the IC chip 5 and the first electrode 41 and the back side connection portion 12 connecting the IC chip 5 and the second electrode 42 are disconnected. As a result, the first electrode 41 and the second electrode 42 are disconnected from the IC chip 5. Therefore, the current does not flow through the first electrode 41 and the second electrode 42. The capacitance accumulated between the first electrode 41 and the second electrode 42 is smaller than that in the improper unsealed state, and the measured value of the capacitance becomes 0.

[0097] When a user brings an external device close to the opening detection label 1 provided on the side of the wine bottle 2 of the labeled container 10, the IC chip 5 of the opening detection label 1 communicates with the external device via the antenna unit 6. The IC chip 5 receives a command from the external device and measures the capacitance accumulated between the first electrode 41 and the second electrode 42.

[0098] For example, in the case where the IC chip 5 stores information about the capacitance in the unopened state, the capacitance measured by the IC chip 5 in the normal unsealed state changes relative to the capacitance in the unopened state, so it is detected as an unsealed state. In addition, the capacitance measured by the IC chip 5 is smaller than the capacitance in the unopened state, and the measured value of the capacitance is 0, so the IC chip 5 can be detected as a normal unsealed state. In addition, the external instrument stores information about the capacitance in the unopened state in the application, so that the capacitance obtained from the IC chip 5 through wireless communication is smaller than the capacitance in the unopened state, and the measured value is 0, so it can be detected as a normal unsealed state.

[0099] In this embodiment, the opening detection label 1 has the electrode 4, and the IC chip 5 can measure the capacitance between the first electrode 41 and the second electrode 42 of the electrode 4. Therefore, the IC chip 5 can detect that the wine bottle 2 is opened.

[0100] In addition, in this embodiment, the IC chip of the unsealing detection label 1 can measure the capacitance between the first electrode 41 and the second electrode 42 of the electrode 4. Therefore, the IC chip 5 can detect whether the wine bottle 2 is in an improper unsealing state or a normal unsealing state by storing information on the capacitance in the unsealed state.

[0101] In addition, in the present embodiment, the first electrode 41 and the second electrode 42 are formed to be the same size. Therefore, for example, when the electrical connection between the first electrode 41 or a part of the second electrode 42 and the IC chip 5 is disconnected, the capacitance between the first electrode 41 and the second electrode 42 can be further changed to improve the accuracy of the unsealing detection of the IC chip 5.

[0102] In addition, in this embodiment, the needle detection part 413 of the first electrode 41 is formed in a writing shape in a way that one wire does not cross. Therefore, in the improperly opened state, the area of ​​the first electrode 41 that accumulates capacitance can be reduced by disconnecting the wire of the needle detection part 413. That is, in the case of the improperly opened state, the change in capacitance can be increased compared to the unopened state, and the accuracy of the IC chip opening detection can be improved.

[0103] In the present embodiment, the needle detection portion 413 is formed in a region at least overlapping the opening 22 when viewed from the up-down direction A. Therefore, the IC chip 5 can detect improper opening when the user inserts the injection needle into the opening 22 .

[0104] In addition, in the present embodiment, the needle detection unit 413 is formed in a spiral shape by winding a conductive wire, so that the opening 22 can be covered in a single stroke and the area can be increased efficiently.

[0105] In this embodiment, the line width H1 of the conductive wire of the needle detector 413 and the width H2 between two adjacent conductive wires are each less than or equal to 0.3 mm. Therefore, when the user punctures the cork 23 with a syringe needle, the needle can be detected without omission.

[0106] The first embodiment of the present invention is described in detail above with reference to the accompanying drawings, but the specific structure is not limited to this embodiment, and also includes design changes within the scope of the gist of the present invention. In addition, the structural elements shown in the above embodiment and the modified examples shown below can be appropriately combined.

[0107] (Second Embodiment)

[0108] Next, refer to Figure 7 A second embodiment of the present invention is described. In the following description, the same reference numerals are used for structures common to the structures already described, and repeated descriptions are omitted. In addition, any of the following embodiments is different from the first embodiment in that the surface side connection portion and the first electrode are different. Therefore, in the following description, the description is centered on the differences from the first embodiment.

[0109] Figure 7 It is a diagram showing the structure of an opening detection label 1A for a labeled container according to a second embodiment of the present invention.

[0110] The front-side connection portion 11A extends from the IC chip 5 to the central axis O1 of the first electrode 41A. The base end portion 11Ab of the front-side connection portion 11A is arranged at the same position as the central axis O1 when viewed from the up-down direction A.

[0111] The first electrode 41A includes a plurality of third electrodes 43 . In the present embodiment, the third electrode 43 has its center on the central axis O1 and is formed in a sector shape having substantially the same radius as that of the opening 22 .

[0112] For example, six third electrodes 43 are provided and arranged without a gap of 0.3 mm or more therebetween, forming a circular shape. The third electrode 43 includes a needle detection portion 413A and a first peripheral electrode portion 414A.

[0113] The needle detection part 413A is formed into a fan shape as a whole by folding back multiple times in a staggered (meandering) manner so that the length of the wire increases from the base end 11Ab of the surface side connection part 11A arranged on the central axis O1 toward the outer peripheral side P2. The plurality of needle detection parts 413A are arranged so as not to overlap each other, and at least when viewed from the up-down direction A, no wire crosses or branches in the area overlapping with the opening 22, but is formed into a writing shape.

[0114] The first peripheral electrode portion 414A is electrically connected to the needle detecting portion 413A. The first peripheral electrode portion 414A has substantially the same radius as the opening 22, and is formed in an arc shape with the central axis O1 as the center.

[0115] In this embodiment, in the improperly opened state, no matter where the user punctures the cork 23 with the injection needle, at least one of the fan-shaped third electrodes 43 is disconnected. Therefore, the IC chip 5 can measure the difference in capacitance corresponding to the area of ​​the third electrode 43 and detect improper opening by storing the information of the capacitance in the unopened state.

[0116] The second embodiment of the present invention is described in detail with reference to the drawings, but the specific structure is not limited to this embodiment, and also includes design changes within the scope of the gist of the present invention. In addition, the structural elements shown in the above embodiment and the modified examples shown below can be appropriately combined.

[0117] (Variation Example)

[0118] The first electrode 41 and the second electrode 42 of the unsealing detection label 1 of the above embodiment can be oppositely installed on the surface and back of the substrate 3. In other words, the first electrode 41 can be arranged on the back side of the substrate 3, that is, the lower side A2, and the second electrode 42 can be arranged on the surface side of the substrate 3, that is, the upper side A1.

[0119] In addition, the second peripheral electrode portion of the second electrode 42 involved in the above embodiment may not be in the shape of a ring. Fig. 8A The opening detection label 1B shown, Figure 8B As in the illustrated opening detection label 1C, the second peripheral electrode portion 42B may be formed in a disk shape without a through hole, and connected to the IC chip 5 via the back-side connecting portion 12 .

[0120] (Third Embodiment)

[0121] Next, refer to Fig. 9 The third embodiment of the present invention is described. In the following description, the same reference numerals are given to the structures common to the structures already described, and repeated descriptions are omitted. In addition, any of the following embodiments is different from the first embodiment in that it is configured as an opening detection system using a server and an external device. Therefore, in the following description, the description will be centered on the differences from the first embodiment.

[0122] [Opening detection system 200]

[0123] Fig. 9 It is a diagram showing the configuration of an opening detection system 200 according to a third embodiment.

[0132] The control unit 303 is configured using a processor such as a CPU. The control unit 303 functions by the processor executing a program stored in the storage unit 302 .

[0133] [External instrument 400]

[0134] The external device 400 is, for example, a communication terminal device that can be carried by a user. The external device 400 is, for example, a mobile phone such as a smartphone, a tablet terminal, a portable personal computer, a wearable terminal, or the like.

[0135] The input unit 401 is composed of existing input devices such as a keyboard, a pointing device (mouse, tablet, etc.), buttons, and a touch panel. The input unit is operated by the user when inputting the user's instructions to the portable terminal device. The input unit can be an interface for connecting the input device to the external device 400.

[0138] The external antenna unit 404 is a communication interface and performs wireless communication with the antenna unit 6 of the opening detection tag 1 of the tagged container 10 by, for example, NFC (Near Field Communication).

[0139] The storage unit 405 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The storage unit 405 stores, for example, program data of an application that operates in the external device 400. The storage unit 405 may also store other information.

[0140] The control unit 406 is configured using a processor such as a CPU (Central Processing Unit). The processor executes a program stored in the storage unit 405 to implement the functions of the control unit 406.

[0141] Next, the operation of the unsealing detection system 200 will be described.

[0142] The opening detection system 200 of this embodiment functions in two states: offline and online. Here, offline refers to a state in which the external device 400 does not communicate with the server 300 via the network 900. Online refers to a state in which the external device 400 can communicate with the server 300 via the network 900.

[0143] The user pre-installs a predetermined application in the external device 400 by operating the external device 400 carried by the user. In the application, the information of the capacitor in the unopened state, the detailed information of the contents (red wine) (such as origin, year, etc.), and other information can be pre-registered in advance through the user's operation.

[0144] [Offline Status]

[0145] First, the operation of the unsealing detection system 200 in an off-line state will be described.

[0146] The user holds the external device 400 and brings the external antenna unit 404 (external device 400) close to the antenna unit 6 of the opening detection label 1. Then, the IC chip 5 of the opening detection label 1 can be supplied with power via the antenna unit 6, measure the capacitance between the first electrode 41 and the second electrode 42, and send the information to the external device 400. In addition, the IC chip 5 can send the identification information for the red wine bottle 2 to the external device 400. The external device 400 stores the acquired information in the storage unit 405.

[0147] Here, when the IC chip 5 of the unsealing detection label 1 stores information on the capacitance in the unsealed state, it is possible to detect whether the wine bottle 2 is in an improper unsealed state or a normal unsealed state when the wine bottle 2 is unsealed, and send the detection information to the external device 400. In addition, when the external device 400 stores information on the capacitance in the unsealed state in the application, the IC chip 5 sends the measured value of the capacitance to the external device 400. The external device 400 can detect whether the unsealing state of the wine bottle 2 is in an improper unsealed state or a normal unsealed state based on the measured value, and generate detection information.

[0148] The user can confirm the detection information through the application. Specifically, when the wine bottle 2 is in an unopened state, the control unit 406 causes the display unit 402 of the external instrument 400 to display the capacitance measured by the IC chip 5 in an unopened state. The user can confirm the unopened state by confirming the display unit 402. Therefore, the user can sell or keep the wine bottle 2 with peace of mind. In addition, when the wine bottle 2 is in an improperly unsealed state, the control unit 406 causes the display unit 402 of the external instrument 400 to display the improper unsealing. The user can confirm that it is improperly unsealed by confirming the display unit 402. And, when the wine bottle 2 is in a normal unsealed state, the control unit 406 causes the display unit 402 of the external instrument 400 to display the situation that it is normally unsealed. The user can confirm the normal unsealed state through the display unit 402.

[0149] Here, a specific display example displayed on the external device 400 will be described.

[0150] In this embodiment, if Fig.10 As shown, if the external device 400 is brought close to the IC chip 5, the identification information of the wine bottle 2 is displayed by, for example, an application for determining whether the wine bottle 2 has been improperly opened. The display unit 402 of the external device 400 displays the model (type), ID, URL of product information, illustration 402a indicating whether there has been improper opening, and the like.

[0151] In addition, at least the illustration 402 a indicating the presence or absence of improper opening may be displayed on the display unit 402 .

[0152] In the case where the red wine bottle 2 is not improperly opened (normally opened), Fig.10 As shown, as illustration 402a, a mark that allows visual confirmation of a normal opened state is displayed.

[0153] On the other hand, in the case where the red wine bottle 2 is improperly opened (improperly opened state), Fig.11 As shown, as illustration 402a, a mark that allows visual confirmation of an improperly opened state is displayed.

[0154] In addition, the IC chip 5 sends the identification information of the wine bottle 2 to the external device 400, so that the control unit 406 of the external device 400 can display the detailed information (e.g., origin, year, etc.) of the content (wine) in the identification information on the display unit 402. The user can further confirm the detailed information related to the wine bottle 2 by confirming the display unit 402.

[0155] In addition, the external device 400 can send information input by the user via the input unit 401 to the IC chip 5. Thus, the IC chip 5 can add or update the acquired information. For example, the user can add identification information and send it to the IC chip 5. In addition, the user can make the external device 400 communicate with the opening detection label 1 regularly, and record the time and place of communication and the state at that time in the IC chip 5 in association. Thus, in the case where the red wine bottle 2 is improperly opened, the labeled container 10 can make the user speculate to some extent at what time and where the improper behavior was carried out through the external device 400.

[0156] [Online Status]

[0157] Next, the operation of the unsealing detection system 200 in an online state will be described.

[0158] The user holds the external device 400 and brings the external antenna unit 404 close to the antenna unit 6 of the opening detection label 1. Then, the IC chip 5 of the opening detection label 1 can be supplied with power via the antenna unit 6, measure the capacitance between the first electrode 41 and the second electrode 42, and transmit the capacitance measurement value information or detection information to the external device 400. In addition, the IC chip 5 can transmit the identification information for the wine bottle 2 to the external device 400.

[0159] The communication unit 403 of the external device 400 in the online state transmits the received information to the server 300 via the network 900 manually or automatically.

[0160] If the control unit 303 of the server 300 receives the measured value information or detection information and identification information of the capacitance via the communication unit 301, the information is stored in the storage unit 302 in association with other information. Specifically, the control unit 303 of the server 300 can detect whether the unsealed state of the wine bottle 2 is an improper unsealed state or a normal unsealed state according to the measured value information, and generate detection information. In addition, the control unit 303 of the server 300 can, for example, summarize the detailed information (such as origin, year, etc.) of the content (red wine) of the wine bottle 2 of the identification information, as well as the time of reception (information indicating the moment), the place of reception (information indicating the location), and the information of other wine bottles associated with the identification information according to the received identification information, and generate it as unsealed detection information. The control unit 303 can send the detection information or unsealed detection information to the external instrument 400. In addition, the unsealed detection information can include the detection information.

[0161] The user can use the external device 400 to access the server 300 from the application via the network 900 to obtain the detection information or the opening detection information. In addition, the detection information or the opening detection information can be automatically sent to the external device 400 by email when the email address is pre-registered in the application. In addition, the detection information or the opening detection information can be automatically sent by push notification to the application of the external device 400.

[0162] The user can confirm the detection information or the opening detection information via the display unit 402. Thus, in addition to being able to confirm the above-mentioned opening status, the user can also confirm, for example, at what time and place, how many bottles of what type of product were improperly opened and how many bottles were normally opened, etc., based on the opening detection information. In addition, for example, if the user is the person in charge of a sales store, the number of bottles that were normally opened can be checked and the number of bottles that will be sold next can be grasped to some extent.

[0163] Thus, the opening detection system 200 according to this embodiment allows the user to easily check the opening state using the external device 400 both online and offline. In addition, the opening detection system 200 according to this embodiment allows the user to obtain new information, thereby preventing improper opening and promoting sales.

[0164] The third embodiment of the present invention is described in detail with reference to the drawings, but the specific structure is not limited to this embodiment, and also includes design changes within the scope of the gist of the present invention. In addition, the structural elements shown in the above embodiment and the modified examples shown below can be appropriately combined.

[0165] (Variation Example)

[0166] For example, in the above embodiment, a cork-type wine bottle is cited as an example of a container used in a labeled container, but the invention is not particularly limited. The container may also be a plastic bottle, a beer bottle, a sake bottle, etc. In addition, the cross-sectional shape of the container and the opening is not particularly limited, and may be any shape such as a circle, a triangle, a rectangle, or other shapes. In addition, the size of the container is not particularly limited. In addition, the sealing portion is not limited to a cork, and any component that seals the opening may be used.

[0167] For example, in the above-mentioned embodiment, liquid wine is cited as the content of the wine bottle, but the content may not be liquid.

[0168] The opening detection tag involved in the above-mentioned embodiment can communicate in any frequency band as long as it can perform wireless communication. It is not limited to the UHF band and can also communicate in the HF band, microwave band (near 2.45 GHz), and LF band (less than or equal to 135 kHz).

[0169] In addition, the opening detection label involved in the above-mentioned embodiment can also be additionally provided with protective molds, various resistors, capacitors, rectifier elements, surge arresters, power supplies, power generation elements, display units, modularized electronic circuits and other components.

[0170] In addition, the front side connection part and the back side connection part of the opening detection label involved in the present embodiment can extend in a manner that spans the lowermost end of the cover. According to this structure, for example, even if the user removes the entire cover from the opening and the bottleneck and opens the bottle normally, it can be detected that the front side connection part and the back side connection part are disconnected and the IC chip of the opening detection label is opened normally.

[0171] In any of the above aspects, the opening detection label and labeled container according to the present invention can provide an opening detection label and labeled container that can detect improper replacement of the contents of the container by opening a hole in the sealing portion provided at the opening.

[0172] Industrial Applicability

[0173] According to the opening detection label and the labeled container of the present invention, since a hole is formed in the sealing portion provided at the opening, it is possible to detect that the contents of the container have been improperly replaced, and therefore they can be used industrially.
