Description

本発明は、シールを剥離すると破断する剥離検知線を用いて不正開封やタグのすり替を検知するICタグ内蔵の剥離検知タグに関する。   The present invention relates to a peeling detection tag with a built-in IC tag that detects unauthorized opening or tag replacement using a peeling detection line that breaks when the seal is peeled off.

不正開封やタグのすり替えを電気的に検知する技術として、特許文献1〜3に、剥離検知可能なICタグ内蔵の封印シールやタグシールを用い、これとリーダ/ライタが交信して非接触で開封やすり替えの有無を検知する方法が開示されている。
この方法は、シールを剥がすとICチップとアンテナの接続回路が破断し、通信不能となることからシールの剥離を検知できる。
しかし、この方法ではICチップとアンテナが切り離されてしまうため、剥離されたICタグのIDが読めなくなってしまう。
そのため、該当のICタグが何であったのか判らないばかりでなく、トレーサビリティに利用する場合は履歴情報が追跡できず、どの時点で不正が行われたのか知ることもできないという問題がある。
As a technology for electrically detecting unauthorized opening or tag replacement, Patent Documents 1 to 3 use a seal seal or tag seal with a built-in IC tag that can detect peeling, and this is communicated with the reader / writer to open it without contact. A method for detecting the presence or absence of file replacement is disclosed.
In this method, if the seal is peeled off, the connection circuit between the IC chip and the antenna is broken, and communication becomes impossible, so that peeling of the seal can be detected.
However, in this method, since the IC chip and the antenna are separated, the ID of the peeled IC tag cannot be read.
For this reason, there is a problem that not only the corresponding IC tag is not known but also history information cannot be traced when used for traceability, and it is not possible to know at what point fraud has occurred.

この問題は、例えば特許文献4に示されている剥離検知線(特許文献4では切断検知用回路)をICチップに接続することにより解決できる。
すなわち、シールを剥がしてもICチップとアンテナの接続回路は破断しないが、剥離検知線が破断するのでシールの剥離を検知できる。
このシールは、図7の断面図に示すように、ICチップ1にアンテナ2と剥離検知線3をフィルム基板5の裏側に接着し、それを貼着面にして封印すべきケースなどの開閉部や商品などの被着物9に貼付する。フィルム基板5の表側は上紙7で被覆する。
This problem can be solved, for example, by connecting a peeling detection line shown in Patent Document 4 (a circuit for detecting cutting in Patent Document 4) to the IC chip.
That is, even if the seal is peeled off, the connection circuit between the IC chip and the antenna is not broken, but the peeling detection line is broken, so that peeling of the seal can be detected.
As shown in the cross-sectional view of FIG. 7, the seal is formed by bonding the antenna 2 and the peeling detection line 3 to the IC chip 1 on the back side of the film substrate 5 and sticking it to the opening and closing part of the case or the like to be sealed. Affixed to an adherend 9 such as a product. The front side of the film substrate 5 is covered with an upper paper 7.

しかしながら、このシールはICチップ1、アンテナ2、剥離検知線3がフィルム基板5の裏側にあるため、図8に示すように、フィルム基板5を強く引っ張って急激に剥離したり、図9に示すように、フィルム基板5を鋭角に折り曲げて剥離すると、フィルム基板5の裏側に大きな位置ずれが発生し、フィルム基板5からICチップ1が外れ、ICチップ1とアンテナ2が切り離されてしまうという問題点があった。
このとき剥離検知線3は剥離により分断されて一部が被着物9側に残る。

However, since the IC chip 1, the antenna 2, and the peeling detection line 3 are on the back side of the film substrate 5, this seal peels off sharply by strongly pulling the film substrate 5 as shown in FIG. Thus, when the film substrate 5 is bent at an acute angle and peeled off, a large positional shift occurs on the back side of the film substrate 5, and the IC chip 1 is detached from the film substrate 5, and the IC chip 1 and the antenna 2 are separated. There was a point.
At this time, the peeling detection line 3 is divided by peeling and a part remains on the adherend 9 side.

解決しようとする問題点は以上のような点であり、本発明は、シールを急激に剥離したり鋭角に折り曲げてもフィルム基板からICチップが外れないようにすることを目的になされたものである。   The problems to be solved are as described above, and the present invention is intended to prevent the IC chip from being detached from the film substrate even when the seal is peeled off rapidly or bent at an acute angle. is there.

そのため本発明は、シールを剥離すると破断する剥離検知線をICタグに接続して非接触でシールの剥離を検知するICタグ内蔵のタグにおいて、前記ICタグがシール基板の表側に、前記剥離検知線がシール貼着面であるシール基板の裏側にそれぞれ分離配置されていることを最も主要な特徴とする。   Therefore, the present invention provides a tag with a built-in IC tag that detects a peeling of the seal in a non-contact manner by connecting a peeling detection line that breaks when the seal is peeled off to the IC tag. The most important feature is that the lines are separately arranged on the back side of the seal substrate, which is the seal attachment surface.

本発明は、ICタグをシール基板の表側に、剥離検知線をシール基板の裏側に配置するので、シールを急激に剥離したり鋭角に折り曲げると、シール基板裏側の剥離検知線は容易に剥がれ落ちるが、シール基板の表側は裏側に比べ位置ずれが小さく、かつシール基板が下支えするので、従来のようにシール基板から内蔵のICチップが外れるようなことはなくなる。
また、ICタグと剥離検知線が異なる面に存在するので、アンテナパターンとの重なりを気にすることなく、剥離検知線の配線を自由にデザインできる。
また、破損してはならないICタグと容易に破損すべき剥離検知線がシール基板の表裏に配置されるので、相反する機能条件を容易に実現でき、製造が容易になり、品質が向上する。
In the present invention, since the IC tag is arranged on the front side of the seal substrate and the peeling detection line is arranged on the back side of the sealing substrate, the peeling detection line on the back side of the sealing substrate is easily peeled off when the seal is peeled off rapidly or bent at an acute angle. However, the front side of the seal substrate is less misaligned than the back side, and the seal substrate supports, so that the built-in IC chip is not detached from the seal substrate as in the prior art.
Further, since the IC tag and the peeling detection line exist on different surfaces, the wiring of the peeling detection line can be freely designed without worrying about overlapping with the antenna pattern.
In addition, since the IC tag that should not be damaged and the peeling detection line that should be easily damaged are arranged on the front and back of the seal substrate, conflicting functional conditions can be easily realized, manufacturing becomes easy, and quality improves.

以下、本発明の実施の形態について説明する。   Embodiments of the present invention will be described below.

粘着層3aには、例えば一度貼着すると剥がすのが困難な強粘着性の粘着剤を使用し、粘着層3bには、貼着しても容易に剥がせる仮止め用の弱粘着性の粘着剤を使用する。
または、フィルム基板5の裏面に離形剤を塗布し、その上に剥離検知線3を形成すると、剥離検知線3全体が容易に剥がれるようになる。
The film substrate 5 and the upper paper 7 are formed of a resin such as PET or polyester.
The antenna 2 forms a pattern of a metal material such as a copper foil or an aluminum foil, or a conductive material such as a carbon compound, a conductive ink, or a conductive polymer on the film substrate 5 by photolithography or screen printing.
The peeling detection line 3 is a strip-shaped conductor formed of a fragile metal material or a conductive material, and is adhered between the film substrate 5 and the release paper 8 via adhesive layers 3a and 3b as shown in FIG. . The adhesive layers 3a and 3b are formed by alternately arranging two types of adhesives having different adhesive strengths in a stripe shape, and in the entire region in the length direction of the peeling detection line 3, two types of adhesives are provided on the upper surface and the lower surface. It arrange | positions so that layer 3a, 3b may be located alternately.
For the adhesive layer 3a, for example, a strong adhesive that is difficult to peel off once applied is used, and for the adhesive layer 3b, a weak adhesive for temporary fixing that can be easily peeled even after being applied. Use the agent.
Or if a release agent is apply | coated to the back surface of the film substrate 5, and the peeling detection line 3 is formed on it, the peeling detection line 3 whole comes to peel easily.

本発明を実施した剥離検知タグは以上のような構成で、インレット6を剥離紙8から引き剥がし、被着物9に貼付する。
このインレット6を被着物9から無理に剥がすと、図6に示すように、剥離検知線3は弱粘着性の粘着層3bに支持された部分が剥離し、強粘着性の粘着層3aに支持された部分はインレット6または被着物9のいずれか一方の側に貼着したまま残る。
その結果、剥離検知線3がインレット6側と被着物9側に寸断されるため、インレット6の剥離を電気的に検知することができる。
このとき剥離検知線3だけが破損し、ICチップ1とアンテナ2はフィルム基板5と上紙7の間に保護されるので、急激に剥離したり鋭角に曲げてもフィルム基板5から脱落したり破損しないので、ICタグの読み取りが剥離された後でも支障なくできる。
The peel detection tag embodying the present invention has the above-described configuration, and the inlet 6 is peeled off from the release paper 8 and attached to the adherend 9.
When this inlet 6 is forcibly peeled off from the adherend 9, as shown in FIG. 6, the part of the peeling detection line 3 supported by the weak adhesive layer 3b peels off and is supported by the strong adhesive layer 3a. The applied portion remains adhered to either the inlet 6 or the adherend 9.
As a result, since the peeling detection line 3 is cut into the inlet 6 side and the adherend 9 side, peeling of the inlet 6 can be electrically detected.
At this time, only the peeling detection line 3 is damaged, and the IC chip 1 and the antenna 2 are protected between the film substrate 5 and the upper paper 7, so that even if they are suddenly peeled off or bent at an acute angle, they may fall off the film substrate 5. Since it is not damaged, reading of the IC tag can be performed without any trouble even after peeling.
