Abstract

<P>PROBLEM TO BE SOLVED: To provide a sealing structure, an unsealing determination method, and a tag capable of easily and reliably determining whether or not a hermetic container is unsealed. <P>SOLUTION: In a hermetic container 1 in which an opening part is tightly closed by a plug 3, and a portion in a vicinity of the opening part is sealed by a sealing cover 4, a tag 7 is fixed with adhesive to at least a part of an unsealing part of the sealing cover 4, and a circuit pattern of the tag 7 is formed in the sealing cover itself. Only the tag 7 cannot be taken out of the sealing cover 4 thereby, and if the sealing cover 4 is unsealed, the tag 7 is positively broken. Since the tag 7 is hardly replicated, it can be determined whether or not the hermetic container 1 is unsealed by checking whether or not the tag 7 is a regular one. In addition, as the tag 7 is fitted to the surface of the sealing cover 4, and illegal unsealing can be suppressed. <P>COPYRIGHT: (C)2006,JPO&NCIPI

このように、本発明の構成によれば、タグを封止カバーから取り外すことができず、また、封止カバーの開封時に、表面に接着された又は一体的に形成されたタグが破壊され、このタグは複製が困難であるため、タグの有無又はタグが正規なタグであるかを調べることにより、密閉容器が開封されたか否かを簡単に判別することができる。また、タグを目視可能に封止カバーに取り付け又はタグの回路パターンを目視可能に封止カバーに形成することによって、不正な開封を抑止することができる。   Thus, according to the configuration of the present invention, the tag cannot be removed from the sealing cover, and when the sealing cover is opened, the tag bonded to the surface or integrally formed is destroyed, Since this tag is difficult to duplicate, it can be easily determined whether or not the sealed container has been opened by checking the presence or absence of the tag or whether the tag is a regular tag. Moreover, unauthorized opening can be suppressed by attaching a tag to a sealing cover so that visual recognition is possible, or forming a circuit pattern of a tag in a sealing cover so that visual recognition is possible.

以上説明したように、本発明の封止構造及び開封判別方法並びにタグによれば、下記記載の効果を奏する。   As described above, according to the sealing structure, opening determination method, and tag of the present invention, the following effects can be obtained.

本発明の第１の効果は、密閉容器が開封されたか否かを簡単に判別することができるということである。   The first effect of the present invention is that it is possible to easily determine whether or not the sealed container has been opened.

その理由は、容器本体の開口部近傍を覆う封止カバーに接着剤などによってタグが強固に固定され、又、封止カバー自体にタグの回路パターンが一体的に形成されているため、複製が困難なタグのみを封止カバーから取り外すことができず、また、封止カバーが開封されると確実にタグが破壊されるため、タグの有無又はタグの動作を調べることによって、封止カバーが開封されたか否かを判別することができるからである。 The reason is that the tag is firmly fixed to the sealing cover covering the vicinity of the opening of the container body by an adhesive or the like, and the circuit pattern of the tag is integrally formed on the sealing cover itself, so that the copy is Only difficult tags cannot be removed from the sealing cover, and when the sealing cover is opened, the tag is surely destroyed. This is because it can be determined whether or not the package has been opened.

本発明の第２の効果は、不正な開封を抑止することができるということである。   The second effect of the present invention is that unauthorized opening can be suppressed.

その理由は、封止カバーの表面に目視可能にタグが取り付けられ、又は、封止カバーにタグの回路パターンが目視可能に形成されているため、不正な開封を判別する手段が設けられていることを第三者に認識させることができるからである。   The reason is that the tag is visibly attached to the surface of the sealing cover, or the circuit pattern of the tag is visibly formed on the sealing cover, so that means for discriminating unauthorized opening is provided. This is because a third party can recognize this.

従来技術で示したように、栓によって密閉された瓶の注ぎ口近傍に封止目的で設けられる封止カバーは安価かつ容易に製造することが可能であるため、第三者が瓶を不正に開封し、中身を入れ替えたり薄めた後に、再度、同様の封止カバーを形成して元の状態に戻すことができる。そのため、封止カバーが開封されているか否かを調べるだけでは、瓶が不正に開封されたか否かを判別することができないという問題があった。   As shown in the prior art, a sealing cover provided for sealing purposes in the vicinity of the spout of a bottle sealed with a stopper can be manufactured inexpensively and easily. After opening and replacing or thinning the contents, a similar sealing cover can be formed again to restore the original state. Therefore, there is a problem that it is not possible to determine whether or not the bottle has been opened illegally only by examining whether or not the sealing cover has been opened.

一方、近年、ＩＣチップを備えたタグとリーダ／ライタ（又はリーダ）との間でデータの交信を行うＲＦＩＤシステムが普及しており、ＲＦＩＤシステムではタグ及びリーダ／ライタの各々に備えたアンテナを用いてデータの交信が行われる。このタグはフィルム状などの任意の形状にすることができ、また、データの交信に際してタグに予め記憶されたＩＤ情報などを参照して認証することができるため複製が難しいという特徴がある。   On the other hand, in recent years, an RFID system that performs data communication between a tag having an IC chip and a reader / writer (or a reader) has become widespread, and the RFID system has an antenna provided in each of the tag and the reader / writer. To communicate data. This tag can be formed into an arbitrary shape such as a film shape, and is characterized in that it is difficult to duplicate because it can be authenticated by referring to ID information stored in the tag in advance when communicating data.

そこで、本発明では、上記タグの特徴を利用して、開口部が栓によって密閉され、開口部近傍が封止カバーによって封止される密閉容器に対して、該封止カバーの開封部の少なくともに一部に重なるようにタグを接着剤で固定したり、開封部の少なくともに一部に重なるように封止カバー自体にタグのアンテナコイルなどの回路パターンを作り込む。これにより、封止カバーからタグのみを取り出すことができず、また、封止カバーを開封すると確実にタグが破壊されるため、封止カバーにタグが取り付けられているか否か、タグが正規のタグであるか否かを調べることにより、密閉容器が開封されたか否かを判別することができる。また、タグが封止カバー表面に取り付けられ、又はタグの回路パターンが目視可能に封止カバーに形成されているため、不正な開封を抑止する効果も得られる。   Therefore, in the present invention, using the characteristics of the tag, at least the opening portion of the sealing cover is sealed with respect to the sealed container in which the opening portion is sealed with a stopper and the vicinity of the opening portion is sealed with the sealing cover. The tag is fixed with an adhesive so as to partially overlap with the adhesive, or a circuit pattern such as an antenna coil of the tag is formed in the sealing cover itself so as to partially overlap with the opening portion. As a result, it is not possible to take out only the tag from the sealing cover, and the tag is surely destroyed when the sealing cover is opened. Therefore, whether the tag is attached to the sealing cover is normal. By checking whether or not the tag is a tag, it can be determined whether or not the sealed container has been opened. Moreover, since the tag is attached to the surface of the sealing cover or the circuit pattern of the tag is formed on the sealing cover so as to be visible, an effect of suppressing unauthorized opening is also obtained.

上記実施形態について詳細に説明すべく、本発明の第１の実施例に係る封止構造及び開封判別方法並びにタグについて、図１乃至図１０を参照して説明する。図１は、第１の実施例に係る封止構造を備えた密閉容器の構成を模式的に示す図であり、図２は、該密閉容器の開口部近傍を拡大した図、図３は、そのＡ−Ａ’線における断面図である。また、図４は、封止カバーに固定されるタグの構造を示す図であり、図５は、ＲＦＩＤシステムの構成を模式的に示す図である。また、図６は、封止カバーを開封する前後の状態を示す図であり、図７乃至図９は、本実施例の封止構造のバリエーションを示す図である。また、図１０は、封止カバーが開封されたか否かを判別する手順を示すフローチャート図である。   In order to describe the above embodiment in detail, a sealing structure, an opening determination method, and a tag according to a first example of the present invention will be described with reference to FIGS. FIG. 1 is a diagram schematically showing a configuration of a sealed container having a sealing structure according to the first embodiment, FIG. 2 is an enlarged view of the vicinity of an opening of the sealed container, and FIG. It is sectional drawing in the AA 'line. FIG. 4 is a diagram showing a structure of a tag fixed to the sealing cover, and FIG. 5 is a diagram schematically showing a configuration of the RFID system. Moreover, FIG. 6 is a figure which shows the state before and behind opening a sealing cover, and FIG. 7 thru | or FIG. 9 is a figure which shows the variation of the sealing structure of a present Example. FIG. 10 is a flowchart showing a procedure for determining whether or not the sealing cover has been opened.

図１乃至図３に示すように、本実施例の密閉容器１は、アルコールなどの内容物５を充填するガラスなどで形成された容器本体２と、該容器本体２の開口部（注ぎ口）を密閉するアルミなどで形成された栓３と、開口部近傍の容器本体２及び栓３を覆い、開封するための構造（ここでは手で摘むための取っ手１０や切取線８ａ）が予め設けられた熱収縮性プラスチックなどからなる封止カバー４と、封止カバー４の切取線８ａの少なくとも一部に重なる領域に接着剤９などによって強固に固定されたタグ７とで構成される。   As shown in FIGS. 1 to 3, the sealed container 1 of the present embodiment includes a container body 2 formed of glass or the like filled with a content 5 such as alcohol, and an opening (spout) of the container body 2. The heat is provided in advance with a stopper 3 formed of aluminum or the like for sealing the container, and a structure for covering and opening the container body 2 and the stopper 3 in the vicinity of the opening (here, the handle 10 for picking by hand and the cutting line 8a). The sealing cover 4 is made of a shrinkable plastic and the like, and the tag 7 is firmly fixed to the region that overlaps at least a part of the tear line 8a of the sealing cover 4 with an adhesive 9 or the like.

なお、図１乃至図３の構造は例示であり、内容物５はアルコールに限らず、水などの他の液体や密封状態で保存する薬品などの固体、ガスなどの気体としてもよい。また、容器本体２や栓３の形状、材料なども任意であり、例えば、図９に示すように、栓３として開口部内部に挿入されるコルクなどを用いてもよい。また、封止カバー４の開封構造も図の構成に限定されず、例えば、図７に示すように、切取線８ａが開口部の周回方向に形成された構造としてもよいし、図８に示すように、切取線８ａを１本として切取線８ａの両側を捻ることによって封止カバー４が分断される構造としてもよいし、封止カバー４の厚さを部分的に薄くして破れやすくする構造などとしてもよい。   The structure of FIGS. 1 to 3 is an example, and the content 5 is not limited to alcohol, but may be other liquids such as water, solids such as chemicals stored in a sealed state, or gases such as gases. Moreover, the shape, material, etc. of the container main body 2 and the stopper 3 are arbitrary. For example, as shown in FIG. 9, a cork inserted into the opening as the stopper 3 may be used. Further, the opening structure of the sealing cover 4 is not limited to the configuration shown in the figure. For example, as shown in FIG. 7, the cut line 8a may be formed in the circumferential direction of the opening, or as shown in FIG. Alternatively, the structure may be such that the sealing cover 4 is divided by twisting both sides of the cutting line 8a with one cutting line 8a, or the thickness of the sealing cover 4 is partially reduced to facilitate tearing. Also good.

また、タグ７を固定する接着剤９は特に限定されないが、接着力が弱いとタグ７を取り外した後に封止カバー４を分断し、内容物５の構成に変更を加えた後に同様の封止カバー４を被せ、その上に取り外したタグ７を再度接着するといった偽装が行われる恐れがあるため、封止カバー４とタグ７の材料などを考慮して容易に剥がすことができない接着剤９を選択することが好ましく、例えば、封止カバー４及びタグ７の基材としてポリ塩化ビニルが用いられる場合は、変成シリコーン樹脂系やエポキシ樹脂系の接着剤などを用いることができる。なお、タグ７の固定手段は接着剤９に限定されず、強度が確保できる限りにおいて粘着材を用いたり、熱圧着などの方法で固定してもよい。   Further, the adhesive 9 for fixing the tag 7 is not particularly limited, but if the adhesive strength is weak, the sealing cover 4 is divided after the tag 7 is removed and the configuration of the contents 5 is changed, and then the same sealing is performed. Since there is a possibility that camouflaging such as attaching the cover 4 and reattaching the tag 7 removed thereon is performed, the adhesive 9 that cannot be easily removed in consideration of the material of the sealing cover 4 and the tag 7 is used. For example, when polyvinyl chloride is used as the base material of the sealing cover 4 and the tag 7, a modified silicone resin-based or epoxy resin-based adhesive can be used. Note that the means for fixing the tag 7 is not limited to the adhesive 9, and an adhesive may be used as long as the strength can be secured, or the tag 7 may be fixed by a method such as thermocompression bonding.

また、図４及び図５に示すように、封止カバー４に固定されるタグ７は、共振回路７ｂを構成するアンテナコイル７ａ及びコンデンサ（ＩＣ７ｃに容量を備える場合は必ずしも必要ではない。）と、必要に応じてＩＤ情報などを記憶するＩＣ７ｃとで構成される。このタグ７には、封止カバー４を切取線８ａに沿って分断する際にタグ７が容易に破壊されるように、封止カバー４の切取線８ａに対応する位置に、タグ７の基材７ｄの表裏を貫通する孔が線状に配列された切取線８ｂを設けることが好ましい。なお、図４では、アンテナコイル７ａを二重のループとしているが、アンテナコイル７ａは切取線８ｂと少なくとも一回交差する形状であればよく、ループの数、形状などは任意である。また、図４下部に示すように、切取線８ａは、その貫通孔がアンテナコイル７ａなどの回路パターンを分断しないように形成する。また、タグ７の基材７ｄが切断できるように薄く形成されている場合や切断可能な材料で形成されている場合、又は、ナイフなどを用いてタグ７を切断することを前提にしている場合には切取線８ｂは設ける必要はない。   Further, as shown in FIGS. 4 and 5, the tag 7 fixed to the sealing cover 4 is an antenna coil 7a and a capacitor (not necessarily required when the IC 7c has a capacity) constituting the resonance circuit 7b. The IC 7c stores ID information and the like as necessary. The tag 7 has a base material 7d of the tag 7 at a position corresponding to the tear line 8a of the sealing cover 4 so that the tag 7 is easily broken when the sealing cover 4 is divided along the tear line 8a. It is preferable to provide a tear line 8b in which holes penetrating the front and back are arranged linearly. In FIG. 4, the antenna coil 7 a is a double loop, but the antenna coil 7 a may have any shape that intersects the cutoff line 8 b at least once, and the number and shape of the loops are arbitrary. Further, as shown in the lower part of FIG. 4, the cut line 8a is formed so that the through hole does not divide a circuit pattern such as the antenna coil 7a. Further, when the base material 7d of the tag 7 is thinly formed so that it can be cut, formed of a material that can be cut, or when it is assumed that the tag 7 is cut using a knife or the like. It is not necessary to provide the cut line 8b.

また、リーダ／ライタ６は、タグ７と交信するリーダ／ライタ用アンテナ６ａと送受信信号を変換するための通信回路部６ｂと送受信信号をデコードするための演算処理部６ｃとを主な構成要素とする。このリーダ／ライタ６は、図１に示すような携帯型としてもよいし、設置型としてもよい。そして、リーダ／ライタ用アンテナ６ａをタグ７に近づけると、リーダ／ライタ６とタグ７との間でデータの交信が行われ、リーダ／ライタ６はＩＣ７ｃに予め記憶されたＩＤ情報などを参照して該タグ７が正規のタグであるかを判別する。   The reader / writer 6 includes a reader / writer antenna 6a that communicates with the tag 7, a communication circuit unit 6b for converting transmission / reception signals, and an arithmetic processing unit 6c for decoding transmission / reception signals. To do. The reader / writer 6 may be a portable type as shown in FIG. 1 or an installation type. When the reader / writer antenna 6a is brought close to the tag 7, data communication is performed between the reader / writer 6 and the tag 7, and the reader / writer 6 refers to ID information stored in advance in the IC 7c. Thus, it is determined whether the tag 7 is a regular tag.

次に、上記封止構造が形成された密閉容器１を用いて、封止カバー４が開封されたか否かを判定する手順について、図１０のフローチャート図を参照して説明する。   Next, a procedure for determining whether or not the sealing cover 4 has been opened using the sealed container 1 in which the sealing structure is formed will be described with reference to the flowchart of FIG.

まず、ステップＳ１０１で、醸造所などで容器本体２にアルコールなどの内容物５を充填し、開口部に栓３を被せて閉栓し、引き続き、ステップＳ１０２で、開口部近傍の容器本体２及び栓３の少なくとも一部を覆うように、すなわち、封止カバー４を開封しなければ内容物５を取り出すことができないように、開封構造が設けられた封止カバー４を形成する。この封止カバー４の製造方法は特に限定されないが、例えば、ロール状に巻かれたポリ塩化ビニルやポリエチレンテレフタレートなどの熱収縮性プラスチックフィルムを開口部の円周より若干長く引き出し、切取線８ａを形成してから切断し、切断した短冊状の断片を円筒状に丸めて開口部に被せ、熱を加えて両端部分を連結すると共に全体を熱収縮させる方法などを用いることができる。   First, in step S101, the container body 2 is filled with contents 5 such as alcohol in a brewery or the like, and the opening 3 is covered with the stopper 3, and then in step S102, the container body 2 and the stopper near the opening are closed. The sealing cover 4 provided with the opening structure is formed so that at least a part of the cover 3 is covered, that is, the contents 5 cannot be taken out unless the sealing cover 4 is opened. The manufacturing method of the sealing cover 4 is not particularly limited. For example, a heat-shrinkable plastic film such as polyvinyl chloride or polyethylene terephthalate wound in a roll shape is drawn out slightly longer than the circumference of the opening to form the cut line 8a. Then, the cut strip-shaped piece is rounded into a cylindrical shape and covered with the opening, and heat is applied to connect both end portions and the whole is thermally contracted.

次に、ステップＳ１０３で、上記封止カバー４の所定の場所にタグ７を固定する。このタグ７には、上述したように封止カバー４の開封に際して容易に破壊されるように、必要に応じて、封止カバー４の切取線８ａに対応する位置に切取線８ｂが形成されている。そして、封止カバー４の切取線８ａの一部を跨ぎ（必ずしも図１及び図２に示すように切取線８ａを横断する必要はなく、切り取られる部分と残る部分とを跨いでいればよい。）、かつ、封止カバー４の切取線８ａとタグ７の切取線８ｂとがほぼ重なるように、接着剤９などを用いて貼り付ける。なお、接着剤９の塗布方法は任意であり、封止カバー４側に塗布してもタグ７側に塗布してもよい。また、接着剤９は接着面の全面に塗布してもよいが、接着剤９を接着面の全面に塗布すると、切取線８ａ及び８ｂの貫通孔に接着剤９がしみ込み、切り取りが難しくなる場合も考えられるため、接着剤９が切取線８ａ及び８ｂの貫通孔にしみ込まないように接着面の一部（例えば、切取線を除く全面や四隅など）に塗布してもよい。   Next, in step S103, the tag 7 is fixed to a predetermined place of the sealing cover 4. As described above, a cut line 8b is formed on the tag 7 at a position corresponding to the cut line 8a of the sealing cover 4 so as to be easily broken when the sealing cover 4 is opened. And it straddles a part of the cut line 8a of the sealing cover 4 (it is not always necessary to cross the cut line 8a as shown in FIG. 1 and FIG. 2, it is sufficient to straddle the part to be cut off and the remaining part). And it sticks using the adhesive agent 9 etc. so that the cut line 8a of the sealing cover 4 and the cut line 8b of the tag 7 may overlap. The method for applying the adhesive 9 is arbitrary, and it may be applied to the sealing cover 4 side or the tag 7 side. The adhesive 9 may be applied to the entire surface of the adhesive surface. However, if the adhesive 9 is applied to the entire surface of the adhesive surface, the adhesive 9 penetrates into the through holes of the cut lines 8a and 8b, and it is difficult to cut the adhesive. Therefore, the adhesive 9 may be applied to a part of the adhesive surface (for example, the entire surface excluding the cutoff line or four corners) so that the adhesive 9 does not penetrate into the through holes of the cutoff lines 8a and 8b.

次に、ステップＳ１０４で、上記方法で封止カバー４にタグ７が強固に固定された密閉容器１を出荷して市場に流通させ、ステップＳ１０５で所定の場所に入荷する。この密閉容器１の入荷場所は任意であり、運送会社の倉庫としてもよいし、問屋や小売店などの販売店としてもよいし、外国に出荷する場合は出荷先の税関などとしてもよい。   Next, in step S104, the sealed container 1 in which the tag 7 is firmly fixed to the sealing cover 4 by the above method is shipped and distributed in the market, and in step S105, it is received at a predetermined place. The arrival location of the sealed container 1 is arbitrary, and may be a warehouse of a shipping company, a store such as a wholesale store or a retail store, or a customs destination of a shipping destination when shipping to a foreign country.

そして、以降のステップで、密閉容器１が流通過程で不正に開封されていないかを判定する。ここで、図６（ａ）に示すように、本実施例の密閉容器１には、封止カバー４の開封部にタグ７が取り外せないように、かつ、開封すれば容易に破壊されるように取り付けられているため、第三者の不正な開封を抑止することができるが、タグ７が取り付けられているにもかかわらず、第三者が不正に封止カバー４を分断した場合には、図６（ｂ）に示すように、封止カバー４に固定されたタグ７も切取線８ｂに沿って分断されて破壊される。従って、上記第三者によって一旦封止カバー４が開封されたら、再度封止カバー４を取り付けたとしても密閉容器１にはタグ７がない状態になるため、外観を検査すれば不正に開封されたか否かを判定することができ、ステップＳ１０６で、密閉容器１にタグ７がない場合には、ステップＳ１０９で、封止カバー４が不正に開封されたと判定することができる。   In the subsequent steps, it is determined whether the sealed container 1 has been tampered with during the distribution process. Here, as shown in FIG. 6A, in the sealed container 1 of the present embodiment, the tag 7 cannot be removed from the opening portion of the sealing cover 4 and can be easily broken if opened. Can be prevented from unauthorized opening by a third party, but when the third party illegally cuts off the sealing cover 4 even though the tag 7 is attached. As shown in FIG. 6B, the tag 7 fixed to the sealing cover 4 is also divided along the cut line 8b and destroyed. Therefore, once the sealing cover 4 is opened by the third party, even if the sealing cover 4 is attached again, the sealed container 1 is not in the state of the tag 7, so that it is illegally opened if the appearance is inspected. If the tag 7 is not present in the sealed container 1 in step S106, it can be determined in step S109 that the sealing cover 4 has been tampered with.

通常は上記外観検査で不正な開封を判別することができるが、第三者が一旦封止カバー４を取り外し、中身を入れ替えたり薄めるなど内容物５の構成に変更を加えた後、再度封止カバー４を取り付け、更に、その上に外観上タグ７に見えるようなダミーのタグを取り付ける場合も考えられる。そのような場合には、リーダ／ライタ６を用いてタグ７にアクセスし、必要に応じてタグ７のＩＣ７ｃに予め記憶されたＩＤ情報などを参照して正規なタグ７であるかを判断することによって上記偽装も見抜くことができ、ステップＳ１０７で、正規のタグ７でない場合にはステップＳ１０９で不正に開封されたと判定することができる。なお、ステップＳ１０７の判断をより確実にするために、タグ７のＩＣ７ｃに暗号化された情報を記憶しておくこともでき、このような構成にすればタグ７の複製をより困難にすることができる。   Normally, it is possible to discriminate unauthorized opening by the above-mentioned appearance inspection, but after a third party removes the sealing cover 4 and changes or thins the contents, the content 5 is changed and then sealed again. It is also conceivable to attach a cover 4 and a dummy tag that looks like the tag 7 in appearance. In such a case, the reader / writer 6 is used to access the tag 7, and if necessary, it is determined whether the tag 7 is a legitimate tag 7 by referring to ID information stored in the IC 7c of the tag 7 in advance. Thus, the camouflage can also be detected, and if it is not the regular tag 7 in step S107, it can be determined that the tag is illegally opened in step S109. In addition, in order to make the determination in step S107 more reliable, encrypted information can be stored in the IC 7c of the tag 7. With such a configuration, it becomes more difficult to duplicate the tag 7. Can do.

そして、ステップＳ１０６で封止カバー４にタグ７が取り付けられており、かつ、ステップＳ１０７でそのタグ７が正規のタグ７であると判断される場合には、ステップＳ１０８で、この密閉容器１は未開封と判定することができる。   If the tag 7 is attached to the sealing cover 4 in step S106 and it is determined in step S107 that the tag 7 is a regular tag 7, the sealed container 1 is determined in step S108. It can be determined as unopened.

このように、本実施例では、アルコールなどを充填する容器本体２の開口部近傍に、該容器本体２及び開口部を閉栓する栓３の少なくとも一部を覆う封止カバー４が取り付けられ、その封止カバー４の切取線８ａなどの開封部の少なくとも一部に重なるようにタグ７が強固、かつ開封時に容易に破壊されるように固定されており、かつ、このタグ７は複製が困難であるため、密閉容器１の流通段階で第三者が封止カバー４を開封し、中身を改竄した後、再度封止カバー４を取り付けたとしても、タグ７の有無や必要に応じて正規のタグ７であるかを調べることによって不正な開封を確実に判別することができる。また、上記タグ７は目視できるように貼り付けられているため、上記不正な開封を抑止することもできる。   Thus, in this embodiment, the sealing cover 4 covering at least a part of the container body 2 and the plug 3 for closing the opening is attached in the vicinity of the opening of the container body 2 filled with alcohol or the like. The tag 7 is firmly fixed so as to overlap at least a part of the opening part such as the tear line 8a of the sealing cover 4 and is easily broken when opened, and the tag 7 is difficult to duplicate. Therefore, even if a third party opens the sealing cover 4 at the distribution stage of the sealed container 1, falsifies the contents, and then attaches the sealing cover 4 again, the presence or absence of the tag 7 and a regular tag depending on necessity By checking whether it is 7, it is possible to reliably determine an illegal opening. Further, since the tag 7 is attached so as to be visible, the unauthorized opening can be suppressed.

次に、本発明の第２の実施例に係る封止構造及び開封判別方法並びにタグについて、図１１乃至図１６を参照して説明する。図１１は、第２の実施例に係る封止構造を備えた密閉容器の構成を模式的に示す図であり、図１２は、そのＢ−Ｂ’線における断面図である。また、図１３は、タグが一体的に構成されるタグ付き封止カバーの構造を示す図であり、図１４は、該タグ付き封止カバーを円筒状に丸めた状態を示す図である。また、図１５は、タグ付き封止カバーを開封する前後の状態を示す図であり、図１６は、タグ付き封止カバーが開封されたか否かを判別する手順を示すフローチャート図である。   Next, a sealing structure, an opening determination method, and a tag according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 11 is a diagram schematically showing a configuration of a sealed container having a sealing structure according to the second embodiment, and FIG. 12 is a cross-sectional view taken along the line B-B ′. Moreover, FIG. 13 is a figure which shows the structure of the sealing cover with a tag by which a tag is comprised integrally, and FIG. 14 is a figure which shows the state which rounded this sealing cover with a tag cylindrically. FIG. 15 is a diagram showing a state before and after opening the tagged sealing cover, and FIG. 16 is a flowchart showing a procedure for determining whether or not the tagged sealing cover is opened.

前記した第１の実施例では、封止カバー４の上に別途製作されたタグ７を接着剤９で固定する構造としたが、この構造の場合、ナイフなどを用いて封止カバー４を開封部以外の部分で開封してタグ７を切り抜き、再度形成した封止カバー４の上に切り抜いたタグ７を貼り付けるといった偽装が行われる可能性があり、その場合、タグ７に以前の封止カバー４が接着されていることを見落としてしまうと開封された密閉容器１を誤って未開封と判別してしまう恐れがある。そこで、本実施例ではそのような偽装に対しても開封されたことを確実に判別できるように、封止カバー４とタグ７とを一体的に形成する。   In the first embodiment, the tag 7 separately manufactured on the sealing cover 4 is fixed with the adhesive 9. However, in this structure, the sealing cover 4 is opened using a knife or the like. There is a possibility that the tag 7 is cut off by opening the part other than the part and the tag 7 is pasted on the formed sealing cover 4 again. If it is overlooked that the cover 4 is adhered, the opened sealed container 1 may be mistakenly determined as unopened. Therefore, in this embodiment, the sealing cover 4 and the tag 7 are integrally formed so that it can be reliably determined that the camouflage has been opened even for such camouflage.

具体的には、本実施例の密閉容器１は、図１１及び図１２に示すように、アルコールなどの内容物５を充填するガラスなどで形成された容器本体２と、該容器本体２の開口部を密閉するアルミなどで形成された栓３と、開口部近傍の容器本体２及び栓３を覆い、取っ手１０や切取線８ａなどの開封構造が設けられ、かつ、タグ７のアンテナコイル７ａなどの回路パターンが表面、裏面又は内部に形成された熱収縮性プラスチックなどからなるタグ付き封止カバー４ａとで構成される。   Specifically, as shown in FIGS. 11 and 12, the sealed container 1 of this embodiment includes a container body 2 formed of glass or the like filled with a content 5 such as alcohol, and an opening of the container body 2. Covering the stopper 3 formed of aluminum or the like for sealing the part, the container body 2 and the stopper 3 in the vicinity of the opening, provided with an opening structure such as a handle 10 or a tear line 8a, and an antenna coil 7a of the tag 7 The circuit pattern is constituted by a tag-attached sealing cover 4a made of heat-shrinkable plastic or the like formed on the front surface, back surface or inside.

なお、図１１及び図１２では、説明を容易にするためのアンテナコイル７ａを一重のループとしているが、アンテナコイル７ａは切取線８ｂと少なくとも一回交差する形状であればよく、ループの数、形状などは任意である。また、切取線８ａは、その貫通孔がアンテナコイル７ａなどの回路パターンを分断しないように形成されていればよく、開口部の周回方向に形成してもよいし、切取線８ａを１本として切取線８ａの両側を捻ることによってタグ付き封止カバー４ａが分断される構造としてもよいし、開封構造としてタグ付き封止カバー４ａの厚さを部分的に薄くして破れやすくする構造などとしてもよい。また、第１の実施例と同様に、内容物５はアルコールに限らず、水などの他の液体や密封状態で保存する薬品などの固体、ガスなどの気体としてもよいし、栓３を注ぎ口に挿入されるコルクなどとしてもよい。   11 and 12, the antenna coil 7a for ease of explanation is a single loop. However, the antenna coil 7a may have a shape that intersects the cut line 8b at least once. Etc. are arbitrary. Moreover, the cut line 8a should just be formed so that the through-hole may not divide circuit patterns, such as the antenna coil 7a, may be formed in the surrounding direction of an opening part, and the cut line 8a is made into one and the cut line 8a. It is good also as a structure where the sealing cover 4a with a tag is parted by twisting both sides of this, and it is good also as a structure etc. which make the thickness of the sealing cover 4a with a tag thin partially, and torn easily as an opening structure. As in the first embodiment, the contents 5 are not limited to alcohol, but may be other liquids such as water, solids such as chemicals stored in a sealed state, gases such as gas, and the stopper 3 is poured. It may be a cork inserted into the mouth.

そして、リーダ／ライタ用アンテナ６ａをタグ付き封止カバー４ａに近づけると、リーダ／ライタ６とタグ付き封止カバー４ａに形成されたタグとの間でデータの交信が行われ、リーダ／ライタ６はＩＣ７ｃに予め記憶されたＩＤ情報などを参照して該タグが正規のタグであるかを判別する。   When the reader / writer antenna 6a is brought close to the tag-attached sealing cover 4a, data is communicated between the reader / writer 6 and the tag formed on the tag-attached sealing cover 4a. Determines whether the tag is a regular tag by referring to ID information or the like stored in advance in the IC 7c.

次に、上記封止構造が形成された密閉容器１を用いて、タグ付き封止カバー４ａが開封されたか否かを判断する手順について、図１６のフローチャート図を参照して説明する。   Next, a procedure for determining whether or not the tagged sealing cover 4a has been opened using the sealed container 1 in which the sealing structure is formed will be described with reference to the flowchart of FIG.

まず、ステップＳ２０１で、醸造所などで容器本体２にアルコールなどの内容物５を充填し、開口部に栓３を被せて閉栓し、引き続き、ステップＳ２０２で、開口部近傍の容器本体２及び栓３の少なくとも一部を覆うように、予め開封構造が設けられ、かつ、アンテナコイル７ａなどの回路パターンが形成されたタグ付き封止カバー４ａを形成する。このタグ付き封止カバー４ａの製造方法は特に限定されないが、例えば、図１３に示すように、予めアンテナコイル７ａなどの回路パターンが形成されたポリ塩化ビニルやポリエチレンテレフタレートなどの熱収縮性プラスチックフィルムを開口部の円周より若干長く引き出し、切取線８ａを形成してから切断し、回路パターンにＩＣ７ｃを接続した後、図１４に示すように、切断した短冊状の断片を円筒状に丸めて開口部に被せ、熱を加えて両端部分を接続すると共に全体を熱収縮させる方法などを用いることができる。   First, in step S201, the container body 2 is filled with a content 5 such as alcohol in a brewery or the like, and the opening 3 is covered with the stopper 3, and subsequently, in step S202, the container body 2 and the stopper near the opening are closed. 3 is formed in advance so as to cover at least a part of the cover 3, and a sealing cover 4a with a tag on which a circuit pattern such as an antenna coil 7a is formed. The manufacturing method of the sealing cover 4a with the tag is not particularly limited. For example, as shown in FIG. 13, a heat-shrinkable plastic film such as polyvinyl chloride or polyethylene terephthalate in which a circuit pattern such as the antenna coil 7a is formed in advance. Is pulled out slightly longer than the circumference of the opening, cut after forming the cut line 8a, and the IC 7c is connected to the circuit pattern. Then, as shown in FIG. For example, a method may be used in which heat is applied to connect both end portions and the whole is thermally contracted.

なお、アンテナコイル７ａなどの回路パターンはタグ付き封止カバー４ａの表面、裏面又は内部のいずれに形成してもよいし、表面又は裏面に形成した場合に更にプラスチックフィルムなどで保護してもよい。表面側に形成した場合には第三者の回路パターンがあることを認識させることができるため、不正な開封を抑止することができ、また、裏面側や内部に形成した場合や表面に印刷が施されている場合には回路パターンを隠すことができるため、タグ付き封止カバー４ａにタグが組み込まれていること自体を秘匿することができる。   The circuit pattern such as the antenna coil 7a may be formed on the front surface, the back surface, or the inside of the tag-attached sealing cover 4a, and when formed on the front surface or the back surface, it may be further protected with a plastic film or the like. . When it is formed on the front side, it can be recognized that there is a third-party circuit pattern, so that unauthorized opening can be suppressed, and when it is formed on the back side or inside, printing is performed on the front side. Since the circuit pattern can be concealed when applied, it is possible to conceal that the tag is incorporated in the sealing cover 4a with tag itself.

次に、ステップＳ２０３で、上記方法でタグ付き封止カバー４ａが形成された密閉容器１を出荷して市場に流通させ、ステップＳ２０４で所定の場所に入荷する。この密閉容器１の入荷場所は任意であり、運送会社の倉庫としてもよいし、問屋や小売店などの販売店としてもよいし、外国に出荷する場合は出荷先の税関などとしてもよい。   Next, in step S203, the sealed container 1 with the tagged sealing cover 4a formed by the above method is shipped and distributed to the market, and in step S204, it is received in a predetermined place. The arrival location of the sealed container 1 is arbitrary, and may be a warehouse of a shipping company, a store such as a wholesale store or a retail store, or a customs destination of a shipping destination when shipping to a foreign country.

そして、以降のステップで、密閉容器１が流通過程で不正に開封されていないかを判定する。ここで、図１５（ａ）に示すように、本実施例の密閉容器１には、タグ付き封止カバー４ａにタグが組み込まれているため、第三者の不正な開封を抑止することができるが、タグ７が取り付けられているにもかかわらず、第三者が不正にタグ付き封止カバー４ａを分断した場合には、図１５（ｂ）に示すように、タグ付き封止カバー４ａに形成されたアンテナコイル７ａなどの回路パターンが切取線８ａに沿って分断されてタグが機能しなくなる。従って、上記第三者によって一旦タグ付き封止カバー４ａが開封されたら、再度封止カバーを取り付けたとしても該封止カバーにはアンテナコイル７ａなどの回路パターンが形成されていないため、外観を検査すれば不正に開封されたか否かを判定することができ、ステップＳ２０５で、封止カバーに回路パターンがない場合には、ステップＳ２０８で、タグ付き封止カバー４ａが不正に開封されたと判定することができる。   In the subsequent steps, it is determined whether the sealed container 1 has been tampered with during the distribution process. Here, as shown in FIG. 15 (a), since the tag is incorporated in the sealed cover 4a with a tag in the sealed container 1 of the present embodiment, it is possible to prevent unauthorized opening by a third party. If the third party illegally cuts off the tagged sealing cover 4a even though the tag 7 is attached, as shown in FIG. 15B, the tagged sealing cover 4a The circuit pattern such as the antenna coil 7a formed on the substrate is divided along the cut line 8a, so that the tag does not function. Therefore, once the tagged sealing cover 4a is opened by the third party, even if the sealing cover is attached again, the circuit pattern such as the antenna coil 7a is not formed on the sealing cover. If it is inspected, it can be determined whether or not it has been tampered with. In step S205, if there is no circuit pattern in the sealing cover, it is determined in step S208 that the tagged sealing cover 4a has been tampered with. can do.

通常は上記外観検査で不正な開封を判別ことができるが、第三者が一旦タグ付き封止カバー４ａを取り外し、中身を入れ替えたり薄めるなど内容物５の構成に変更を加えた後、再度、外観上似せた封止カバー（例えば、回路パターンに見える模様を印刷した封止カバーなど）を取り付ける場合も考えられる。そのような場合には、リーダ／ライタ６を用いてタグ付き封止カバー４ａのタグにアクセスし、必要に応じてタグのＩＣ７ｃに予め記憶されたＩＤ情報などを参照して正規なタグであるかを判断することによって上記偽装も見抜くことができ、ステップＳ２０６で、正規のタグでなければステップＳ２０８で不正に開封されたと判定することができる。なお、ステップＳ２０６の判断をより確実にするために、タグのＩＣ７ｃに暗号化された情報を記憶しておくこともでき、このような構成にすればタグ付き封止カバー４ａの複製をより困難にすることができる。   Normally, it is possible to discriminate unauthorized opening by the above-mentioned appearance inspection, but after a third party temporarily removes the tagged sealing cover 4a and changes or thins the contents, the content 5 is changed again. It is also conceivable to attach a sealing cover similar in appearance (for example, a sealing cover printed with a pattern that looks like a circuit pattern). In such a case, the reader / writer 6 is used to access the tag of the tag-attached sealing cover 4a, and if necessary, the tag is a legitimate tag by referring to ID information stored in advance in the IC 7c of the tag. By determining whether or not the above-mentioned camouflage can be detected, it can be determined in step S206 that the tag has not been legitimately opened in step S208. In order to make the determination in step S206 more reliable, the encrypted information can be stored in the IC 7c of the tag. With such a configuration, it is more difficult to duplicate the tagged sealing cover 4a. Can be.

そして、ステップＳ２０５でタグ付き封止カバー４ａに回路パターンが取り付けられており、かつ、ステップＳ２０６でそのタグが正規のタグである場合には、ステップＳ２０７で、この密閉容器１は未開封と判定することができる。   If a circuit pattern is attached to the tagged sealing cover 4a in step S205 and the tag is a regular tag in step S206, it is determined in step S207 that the sealed container 1 is not opened. can do.

このように、本実施例では、アルコールなどを充填する容器本体２の開口部近傍に、該容器本体２及び開口部を閉栓する栓３の少なくとも一部を覆い、タグのアンテナコイル７ａなどの回路パターンが形成されたタグ付き封止カバー４ａが取り付けられており、かつ、このタグ付き封止カバー４ａは複製が困難であるため、密閉容器１の流通段階で第三者がタグ付き封止カバー４ａを開封し、中身を改竄した後、再度封止カバーを取り付けたとしても、回路パターンの有無や必要に応じて正規のタグであるかを調べることによって不正な開封を確実に判別することができる。また、タグの回路パターンを目視できるように形成した場合には、上記不正な開封を抑止することもできる。   As described above, in this embodiment, at least a part of the container body 2 and the plug 3 for closing the opening is covered in the vicinity of the opening of the container body 2 filled with alcohol or the like, and a circuit such as an antenna coil 7a of the tag. Since the tag-attached sealing cover 4a on which the pattern is formed is attached and the tag-containing sealing cover 4a is difficult to duplicate, a third party can attach the tag-containing sealing cover at the distribution stage of the sealed container 1. Even if 4a is opened, the contents are tampered with, and the sealing cover is attached again, it is possible to reliably determine whether or not the tampering has occurred by checking the presence or absence of the circuit pattern and whether it is a legitimate tag as necessary. it can. Further, when the circuit pattern of the tag is formed so as to be visible, the unauthorized opening can be suppressed.

なお、上記各実施例では、本発明の封止構造をガラス瓶に適用する場合について示したが、本発明は上記実施例に限定されるものではなく、例えば、金属やプラスチックなどで形成された任意の形状（例えば、箱型）の容器に対しても同様に適用することができる。その際、金属製の容器では、アンテナで発生する磁束を打ち消すように渦電流が発生するため、アンテナコイル７ａと容器との間に磁性材を挿入したり、更に導電材を挿入することが好ましい。   In each of the above embodiments, the case where the sealing structure of the present invention is applied to a glass bottle has been described. However, the present invention is not limited to the above embodiments, and for example, an arbitrary one formed of metal, plastic, or the like. The present invention can be similarly applied to a container having a shape (for example, a box shape). At that time, in the metal container, an eddy current is generated so as to cancel the magnetic flux generated by the antenna.
