For example, Patent Document 1 discloses a sticker with an IC tag attached to a container with a lid, which includes an antenna portion and an IC chip that is joined to the antenna portion and has a function of communicating via the antenna portion. It is This IC tag-attached seal is joined to an IC chip and has a line portion that is drawn in one stroke and is attached to the upper surface of the lid of a container with a lid. It is possible to detect that the container has been opened.

However, since this IC tag-attached sticker is supposed to be attached from the upper surface of the mouth of the bottle to the neck, etc., it is difficult to apply it to the lid of an easy-peel type container.

Moreover, in Patent Document 2, metal cans such as aluminum cans and steel cans are provided with IC tags that store product information and information related to logistics so that the information can be read well. A sealing metal lid is disclosed.

The metal cover has an unsealing tab having a ring hole, and the IC tag including the IC chip and the antenna is covered with an insulating member to be sealed in the insulating member in an insulating state. is press-fitted into the ring hole to form a metal lid with an IC tag mounted in the ring hole.

However, this metal lid with an IC tag does not have a function of detecting that it has been opened. In addition, since an insulating layer is required at the portion where the label is attached to the metal lid, the label itself cannot be used.

Therefore, there has been a long-awaited development of an IC tag label capable of detecting the opening of the lid of an easy-peel container.

<IC tag label>
(First embodiment)
The IC tag label of the present invention will be described with reference to FIGS. 1(a) and 2. FIG.
The IC tag label according to the first embodiment of the present invention is an easy-peel container lid portion comprising a container body 7, a lid portion 8 for sealing the container body 7, and a pull tab 9 connected to the lid portion 8. 8 is an IC tag label 10 for detecting opening.

The IC tag label according to the first embodiment of the present invention includes, on a label substrate 1, an unsealing detector 3 for detecting that the lid 8 has been unsealed, an antenna coil 2 for enabling communication with an external device, and an IC chip 6 electrically connected to them.

The unsealing detection unit 3 includes an opening 4 that exposes the end of the pull tab 9 folded toward the lid 8, and a slit (not shown) provided across the pull tab 9 that allows the unsealing detection unit 3 to break. A weakening line (not shown) and an unsealing detection wiring 12 for detecting that the lid portion 8 is unsealed are provided.

The unsealing detection wiring 12 and the slit or the weakening line are characterized in that they intersect in plan view.

(Label base material)
The label base material 1 is not particularly limited as long as it is a base material made of an insulating material. For example, organic and inorganic insulating materials can be used. An insulating resin material can be mentioned as an organic insulating material. For example, thermosetting resins and thermoplastic resins. Thermosetting resins include phenolic resins, urea resins, melamine resins, unsaturated polyesters, polyurethanes, epoxy resins, silicone resins, and the like. Examples of thermoplastic resins include various general-purpose plastics, engineering plastics and super engineering plastics. Examples of inorganic insulating materials include insulating glass-based materials and insulating ceramic materials. Alternatively, a composite material of these organic/inorganic insulating materials may be used. Alternatively, the surface of the metal material may be covered with an insulating layer. Using the materials exemplified above, those processed into a film shape or a sheet shape can be suitably used as the label base material.

(antenna coil)
The antenna coil 2 is not particularly limited. Depending on the frequency band, the number of turns and form of the antenna coil differ.

The antenna coil 2 illustrated in FIG. 1(a) is an antenna for use with radio waves in the 13.56 MHz band. It is an antenna coil (loop antenna) with several turns obtained by patterning according to the method.

In addition, when radio waves with a frequency of less than 135 KHz are used, a wound coil (wound antenna) made by winding an insulated conductive wire such as an enamel wire several tens of times or more is used as an antenna coil. When radio waves in the 920 MHz band are used, a dipole antenna obtained by patterning an aluminum foil adhered to a base material such as an insulating film by photolithography is used.

(Open detection part)
The unsealing detector 3 includes an opening 4 exposing the end of the pull-tab 9 folded toward the lid 8, a weakening line 14 extending over the pull-tab 9 so that the unsealing detector 3 can be broken, and an opening. A detection wiring 12 is provided.

(Aperture)
The opening 4 is a portion where the label substrate 1 has been removed to expose the end of the pull tab 9 folded toward the lid 8 .

(weak line)
An IC tag label 10 is stuck on the pull-tab 9 when the lid member 8 is peeled off from the container body 7 by pulling up the pull-tab 9 . Since the label substrate 1 of the IC tag label 10 is made of a resin film such as a PET film, it is difficult to break easily. In order to easily break the pull tab 9 by pulling it up, a slit such as a cut line, a weakening line 14 such as a half cut or a perforation is formed in the label base material 1 with a length not reaching the unsealing detection line 12.例文帳に追加must be kept. For example, a slit perpendicular to the edge of the opening 4 may be formed.
For such weakened lines, it is possible to apply various easy-opening techniques that are used in packaging bags, etc., and that enable easy cutting and opening from any end of the packaging bag.

(Open detection wiring)
The unsealing detection wiring 12 is a closed circuit made up of a conductor pattern formed along the periphery of the opening 4 . If the unsealing detection wiring 12 is broken even at one point, the closed circuit formed by the unsealing detection wiring 12 is broken. A conductor pattern is a line made of a conductive material. For example, it may be formed by patterning copper foil or aluminum foil by photolithography, or may be formed by printing conductive ink. The closed circuit may be formed from a linear pattern as illustrated in FIG. 1(a), or may be a combination of curved lines.

(IC chip)
As illustrated in FIG. 1A, when the unsealing detection wiring 12 consists of a dedicated closed circuit, an IC chip 6 having a disconnection detection circuit is used. An unsealing detection wiring 12 is connected to a dedicated terminal of the IC chip 6 . By doing so, when the lid portion 8 of the easy peel container 20 (see FIG. 2) is opened, the unsealing detection wiring 12 is broken and disconnected. The IC chip 6 can detect the disconnection.

(spacer)
The spacer 11 is formed on the surface opposite to the surface of the label substrate 1 on which the antenna coil 2 of the IC tag label 10 of the present invention is formed. This spacer 11 has a thickness that allows the distance between the antenna coil 2 and the metal surface to be greater than the distance that enables communication even when the IC tag label 10 of the present invention is placed on the metal surface. there is The spacer 11 can be made of any electrically insulating material. For example, films made of electrically insulating resin materials such as polyethylene terephthalate (PET), polyurethane, polyamide, and polyimide can be preferably used.

(Second embodiment)
Next, an IC tag label according to a second embodiment of the present invention will be described with reference to FIGS. 1(b) and 2. FIG.
An IC tag label 10' according to the second embodiment of the present invention includes an antenna coil 2', an unsealing detector 3', an IC chip 6', and an unsealing detection wiring 12'. Different from the tag label 10. Others are the same as the IC tag label 10 according to the first embodiment.

(antenna coil)
The antenna coil 2' is equivalent to the antenna coil 2 in the first embodiment.

(Open detection part)
The unsealing detection unit 3' includes an unsealing detection wiring 12', an opening 4, and a weakening line 14 such as a slit provided across the pull tab 9 and capable of breaking the unsealing detection unit 3'. The openings 4 and weakening lines 14 such as slits may be the same as in the first embodiment. Also, the unsealing detection wiring 12' may be the same as the unsealing detection wiring 12 in the first embodiment. The difference is that the unsealing detection wiring 12' is part of the antenna coil 2'.

(IC chip)
The IC chip 6' only needs to have a connection terminal with the antenna coil 2'. A connection terminal for the unsealing detection wiring 12' may be provided, but it is not necessary to use it. When the opening detection wiring 12' is disconnected, the antenna coil 2' becomes inoperable, so communication with an external communication device becomes impossible and reading becomes impossible. By doing so, it can be determined that the package has been opened.

<Easy peel container with opening function>
FIG. 2 shows an easy peel container 20 with an opening function according to the present invention.
The easy peel container 20 with an unsealing function of the present invention comprises an easy peel container body (hereinafter also referred to as container body) 7 , a lid portion 8 that seals the opening of the container body 7 , and a peripheral edge portion of the lid portion 8 . The pull tab 9 and the IC tag label 10 are provided.

The IC tag label 10 has its unsealing detection wiring 12 adhered across the container body 7 and the lid portion 8 .

Alternatively, the unsealing detection wiring 12 of the IC tag label 10 needs to be adhered across the container body 7, the lid portion 8, and the pull tab 9 folded toward the lid portion 8 side.

Also, when the IC tag label 10 is adhered, the spacer 11 is adhered so as to face the container body 7 and the lid material 8 .

Further, the lid portion 8 is provided with a pull tab 9 that is a grip portion that allows the lid portion 8 to be easily peeled off. The pull tab 9 is provided so as to be connected to the periphery of the lid portion 8 .

(Easy peel container body)
The easy peel container main body 7 is not particularly limited as long as it is a container that stores contents. The easy-peel container main body 7 shown in FIG. 2 shows an example of a cylindrical shape in which one opening is closed and the other is an opening.

(Lid)
The lid portion 8 is provided to seal the opening of the easy peel container main body 7 . As a configuration of the lid portion 8, a configuration in which a heat-welding resin layer such as a heat seal layer is formed on a metal foil such as an aluminum foil can be given. As for the structure of the opening of the easy peel container body 7, it is common to increase the contact area between the opening and the lid 8 for the purpose of increasing the adhesion between the lid 8 and the opening of the easy peel container body 7. is. For example, an eaves-like (or doughnut-like) structure extending inside the opening of the easy peel container body 7 is formed, and the outer peripheral portion of the lid portion 8 is heat-sealed to the structure to ensure the easy peel container body. A lid portion 8 can be thermally welded to the opening of 7 to seal it.

The pull tab 9 is a protruding portion connected to the lid portion 8 that is held with fingers to lift the lid portion 8 and separate it from the container body 7 . It is made of the same material as the lid portion 8 .

Next, examples of the present invention will be described.

<Example 1>
An IC tag label of the present invention was produced as follows. Specifically, as shown in FIG. 1(b), an IC tag label was produced in which the unsealing detection wiring of the unsealing detection unit was a part of the antenna coil.

First, a long laminated material made of double-sided aluminum foil having a layer structure of aluminum foil (thickness 30 μm)/PET film (polyethylene terephthalate film, thickness 38 μm)/aluminum foil (thickness 30 μm) was prepared.

A long laminated material was wound on an unwinding roll, loaded into the unwinding section of a roll-to-roll type processing apparatus, and treated by winding the processed laminated material onto the winding roll of the winding section.
As a roll-to-roll processing device, processing such as lamination of a photosensitive resist film, exposure of a desired pattern, development, etching, washing, drying, and adhesion of a resin film is performed on a long laminated material. I used equipment that could do it.
In addition, as shown in FIG. 3, each IC tag label was produced by attaching multiple faces in the flow direction of the long laminated material.

First, using a roll-to-roll type processing apparatus, the aluminum foil on one side (front side) of the laminated material is etched by photolithography to obtain a film similar to that shown in FIG. 1(b). , a coil antenna, and an unsealing detection wiring as a part of the coil antenna.

Next, the aluminum foil on the other side (back side) is etched in the same way, and the two terminals (called the start terminal and the end terminal) at both ends of the closed circuit where the unsealing detection wiring is part of the antenna coil. ) are placed in close proximity to facilitate connection to the IC chip. Specifically, since the antenna coil is formed between the starting terminal and the terminating terminal, the aluminum foil pattern (Fig. 1(b) dashed line) was formed.

Next, by crimping the PET film at the positions of the start terminal and the end terminal, the terminals on the front and back surfaces were electrically connected.

Next, a line of weakness was formed. As the weakening line, a slit was formed along the outer periphery of the unsealing detection part 3 (see FIG. 1(b)) and perpendicular to the outer peripheral edge so as not to reach the antenna coil.

Next, an IC chip (NTAG213, manufactured by NXP) was adhered to the start terminal and the end terminal with a conductive adhesive.

Next, on the back side, a release paper having the same width as the long laminated material was laminated via an adhesive.

Next, the opening was formed by half-cutting so as to leave the release paper. As shown in FIG. 1(b), the half-cut process forms the unsealing detection line 12' of the unsealing detection part 3 along the periphery of the opening 3 so as not to make a full circle. That is, the notch portion 5 is formed in a portion around the opening portion 3 where the unsealing detection line 12' is not formed. The notch 5 was formed so as to open along the flow direction (longitudinal direction) of the roll-to-roll processing apparatus.

The IC tag label manufactured as described above could be easily peeled off from the release paper, and when peeled off, the opening 3 could be easily removed because of the notch 5 . The IC tag label thus individualized had an antenna size of 15 mm×15 mm, and the size of the IC tag label was 50 mm×70 mm.

This IC tag label was attached across the container body and lid of the easy peel container via a spacer 11 (see FIG. 2(b)). The unsealing detection wiring of the IC tag label straddles the boundary line between the container body and the lid from above the pull-tab that is connected to the lid and is folded from the peripheral edge of the lid toward the lid. affixed. In addition, the unsealing detection wiring was attached so as not to be arranged between the tip of the pull-tab and the boundary of the pull-tab lid.

When pulling up the pull-tab of the easy-peel container with an unsealing detection function thus produced, the IC tag label is easily partly broken along the slit formed in the IC tag label, and the pull-tab is pulled up to the boundary with the lid. was made. As a result, the unsealing detection wiring of the IC tag label was disconnected, and the IC tag label became unable to communicate.

<Example 2>
As shown in FIG. 1(a), an IC tag label was manufactured using a closed circuit independent of the antenna coil as the unsealing detection wiring of the unsealing detection part.

In Example 1, since the antenna coil is formed between the starting terminal and the terminating terminal, an aluminum foil pattern (Fig. 1(b) dashed line) was formed. However, in Example 2, an aluminum foil pattern extending on the back surface of the PET film (broken line in FIG. 1(a)) was formed even when connecting an unsealing detection wiring consisting of an independent closed circuit to the IC chip.

In addition to the pair of terminals that connect to the antenna coil, the IC chip used is an IC chip (NT
AG213TT, manufactured by NXP) was used.

By attaching the IC tag label thus prepared to an easy-peel container in the same manner as in Example 1, an easy-peel container with an unsealing detection function was prepared. When the pull tab of this container was pulled up and the lid was opened, the opening detection wiring of the IC tag label was broken. As a result, although the communication function of the IC tag label was normal as it was, the IC tag label provided information that the lid portion had been opened. This information could be read by an IC tag reader. It was the same as Example 1 except for the above points.
