Description

本発明は、封緘バンドに関する。   The present invention relates to a sealing band.

従来、この種の封緘バンドとしては、下記特許文献1に記載されたものが提案されている。下記特許文献1に記載の封緘具(1)は、頭部(2)と、この頭部(2)の一側面より延長されたバンド体(3)よりなり、頭部(2)の貫通孔(6)内に爪体(9)を揺動可能に突設し、この爪体の前後両端に入口壁(7)と覆い壁(8)とをそれぞれ配置して貫通孔(6)をバンド体(3)が通過可能な程度に狭小に形成し、更に覆い壁(8)によって爪体(9)を操作することが不能に保護してなる、というものである(特許文献1:「特許請求の範囲」参照。)。   Conventionally, what was described in the following patent document 1 was proposed as this kind of sealing band. The sealing tool (1) described in Patent Document 1 below includes a head (2) and a band body (3) extended from one side of the head (2), and a through-hole in the head (2). (6) A claw body (9) is provided so as to be swingable in the claw body, and an inlet wall (7) and a cover wall (8) are respectively arranged at the front and rear ends of the claw body so that the through hole (6) is banded. It is formed so narrow that the body (3) can pass through, and further, the covering wall (8) protects the nail body (9) from being inoperable (Patent Document 1: “Patent Document 1: Patent”). See “Claims”.)

特開平2−32967号公報JP-A-2-32967

しかしながら、特許文献1に記載の封緘具(1)の場合、悪意を持って特殊な操作を行えば、封緘を解くことも可能であり、この点で未だ改良の余地があった。
より具体的に説明すれば、特許文献1に記載の封緘具(1)は、ナイロンやポリプロピレン等の強度な大きな樹脂で一体成形したものである(特許文献1の第2頁左下欄第19行〜第20行参照。)。そのため、このような一体成形品において、頭部(2)の内側に爪体(9)を形成しようとすると、金型の都合上、どうしても開口部(11)ができてしまう(特許文献1の第3図,第5図,第7図参照。)。また、間隙(10)についても、金型の都合上、外面側に小さな開口が形成されてしまう(特許文献1の第3図,第4図,第7図,第8図参照。)。
However, in the case of the sealing tool (1) described in Patent Document 1, if a special operation is performed with malicious intent, it is possible to unlock the sealing, and there is still room for improvement in this respect.
If it demonstrates more concretely, the sealing tool (1) of patent document 1 will be integrally molded with strong resin, such as nylon and a polypropylene (the 2nd page of the lower left column of patent document 1 19th line). -See line 20.) Therefore, in such an integrally molded product, when the nail body (9) is to be formed inside the head (2), an opening (11) is inevitably formed for the convenience of the mold (see Patent Document 1). (See FIGS. 3, 5, and 7.) In addition, a small opening is formed on the outer surface side of the gap (10) due to the convenience of the mold (see FIGS. 3, 4, 7, and 8 of Patent Document 1).

しかし、特許文献1に記載の封緘具(1)の場合、上述のような開口部(11)が存在するため、封緘状態においては、貫通孔(6)に挿通されたバンド体(3)が、開口部(11)を介して見える状態になっている。そのため、例えば、細い治具(例えば、ドライバー、キリ、ピアノ線など。)を開口部(11)へ突っ込めば、その先端でバンド体(3)に対して相応に強い力を加えることができる。   However, in the case of the sealing device (1) described in Patent Document 1, since the opening (11) as described above exists, in the sealed state, the band body (3) inserted through the through-hole (6) is provided. It can be seen through the opening (11). Therefore, for example, if a thin jig (for example, a driver, a drill, a piano wire, etc.) is thrust into the opening (11), a correspondingly strong force can be applied to the band body (3) at the tip.

バンド体(3)は、通常、ある程度は柔軟に弾性変形させることが可能なので、上述のような治具の先端が強く押し当てられた場合には、バンド体(3)が弾性変形する可能性があり、その場合、バンド体(3)は開口部(11)の奥へと押し込まれることになる。このとき、爪体(9)も、バンド体(3)に押されて間隙(10)側へ揺動することになるが、間隙(10)の一端には、上述の通り、外面側に連通する小さな開口が形成されているため、例えば、間隙(10)に針先などを突っ込んで爪体(9)に突き当てれば、爪体(9)を間隙(10)側へ揺動させた位置のまま保持することができる。   Since the band body (3) can be elastically deformed to some extent normally, the band body (3) may be elastically deformed when the tip of the jig as described above is strongly pressed. In that case, the band body (3) is pushed into the back of the opening (11). At this time, the claw body (9) is also pushed by the band body (3) and swings toward the gap (10). However, as described above, one end of the gap (10) communicates with the outer surface side. For example, if a needle tip or the like is pushed into the gap (10) and hits the nail body (9), the nail body (9) is swung toward the gap (10) side. Can be held as it is.

このような状態にしてから、上述のような治具を開口部(11)から引き抜いた場合、弾性変形していたバンド体(3)の形状は復元することになるが、爪体(9)の位置は、バンド体(3)の爪部(3a)から外れた位置のまま保持されることになる。その結果、バンド体(3)を貫通孔(6)から引き抜くことができるようになり、これにより、封緘が解かれてしまうことになる。   In such a state, when the jig as described above is pulled out from the opening (11), the shape of the elastically deformed band body (3) is restored, but the nail body (9) Is held at a position deviated from the claw portion (3a) of the band body (3). As a result, the band body (3) can be pulled out from the through hole (6), and thus the sealing is released.

つまり、上記封緘具(1)の場合、開口部(11)内では、バンド体(3)によって爪体(9)が覆い隠されているものの、バンド体(3)自体を弾性変形させれば爪体(9)を揺動させることができ、この点が悪用されると封緘が解かれてしまうおそれがあった。   That is, in the case of the sealing tool (1), although the claw body (9) is covered with the band body (3) in the opening (11), the band body (3) itself is elastically deformed. The nail body (9) can be swung, and if this point is abused, there is a possibility that the sealing will be released.

なお、単にバンド体(3)が弾性変形するのを抑制するだけでよければ、バンド体(3)の剛性を高めるなどの対策をとるのは一案である。しかし、そのような対策をとると、バンド体(3)を湾曲させにくくなる等、バンド体(3)としての本来の性能が損なわれてしまい、封緘具(1)の使い勝手が著しく悪くなる、という別の問題がある。   If it is only necessary to suppress the elastic deformation of the band body (3), it is one idea to take measures such as increasing the rigidity of the band body (3). However, if such measures are taken, the original performance as the band body (3) is impaired, such as it is difficult to bend the band body (3), and the usability of the sealing device (1) is significantly deteriorated. There is another problem.

以下に説明する技術は、上述のような課題を解決しようとするものであり、その目的の一つは、従来品以上に封緘を解くことが困難な構造とされた封緘バンドを提供することにある。   The technology described below is intended to solve the above-described problems, and one of its purposes is to provide a sealing band having a structure that is more difficult to unseal than conventional products. is there.

以下に説明する封緘バンドは、長手方向に列設された複数の歯を有する帯状部と、前記帯状部の一端に設けられ、前記帯状部が挿通される挿通路を有し、当該挿通路へは前記帯状部を前記一端の反対にある他端側から挿し込み可能で、前記挿通路内には、前記帯状部が前記挿通路に挿通された際に前記歯に引っかかる爪が設けられた挿通部とを備え、前記複数の歯及び前記爪は、前記帯状部が前記挿通路に挿通された際にラチェット機構を構成することにより、前記帯状部が前記挿通路へ挿し込まれる方向へ移動することを許容する一方、前記帯状部が前記挿通路から引き抜かれる方向へ移動することを阻止する状態になり、前記挿通部は、凹部が形成された第一部分と、前記第一部分に対して取り付けられた際に前記凹部の開口を塞ぐ第二部分とを有し、前記第一部分には前記凹部の外周側を囲む周壁部が形成され、当該周壁部には前記凹部を挟んで対向する箇所に第一貫通孔及び第二貫通孔が形成されて、前記第一貫通孔から前記凹部を経て前記第二貫通孔に至る通路が、前記挿通路とされており、しかも、前記爪は、前記凹部の内側で、前記挿通路に挿通された状態にある前記帯状部の一部を挟んで前記開口とは反対側となる位置に配設され、前記帯状部が前記挿通路に挿通された際には、前記帯状部及び前記第二部分の双方によって二重の隔壁が形成されて、当該二重の隔壁によって前記開口が塞がれる。   The sealing band described below has a belt-like portion having a plurality of teeth arranged in the longitudinal direction, and an insertion passage provided at one end of the belt-like portion through which the belt-like portion is inserted. Is capable of inserting the belt-like portion from the other end opposite to the one end, and the insertion passage is provided with a claw that hooks the teeth when the belt-like portion is inserted into the insertion passage. The plurality of teeth and the claws move in a direction in which the belt-like portion is inserted into the insertion passage by forming a ratchet mechanism when the belt-like portion is inserted through the insertion passage. On the other hand, the belt-like portion is prevented from moving in the direction of being pulled out from the insertion passage, and the insertion portion is attached to the first portion having the recess and the first portion. 2nd to close the opening of the recess when The first portion is formed with a peripheral wall portion that surrounds the outer peripheral side of the concave portion, and the peripheral wall portion is formed with a first through hole and a second through hole at locations facing each other across the concave portion. The passage from the first through hole to the second through hole through the recess is the insertion passage, and the claw is inserted into the insertion passage inside the recess. When the band-like part is inserted into the insertion passage, both the band-like part and the second part are arranged at a position opposite to the opening across a part of the band-like part in Thus, a double partition is formed, and the opening is closed by the double partition.

このように構成された封緘バンドによれば、帯状部の一端に設けられた挿通部が有する挿通路に対し、帯状部を他端側から挿し込むと、帯状部が環状になる。このとき、帯状部が有する複数の歯と挿通部が有する爪がラチェット機構を構成し、このラチェット機構は、帯状部が挿通路へ挿し込まれる方向へ移動することを許容する一方、帯状部が挿通路から引き抜かれる方向へ移動することを阻止する。そのため、このような封緘バンドであれば、環状になった帯状部を絞って環の径を小さくすることはできても、帯状部を緩めて環の径を大きくすることはできない。したがって、封緘バンドを封緘対象物に取り付けて、環の径が最も小さくなる状態まで絞れば、その環を破断することなく緩めることはできなくなる。   According to the sealing band configured as described above, when the belt-like portion is inserted from the other end side into the insertion passage of the insertion portion provided at one end of the belt-like portion, the belt-like portion becomes annular. At this time, the plurality of teeth of the belt-like portion and the claw of the insertion portion constitute a ratchet mechanism, and this ratchet mechanism allows the belt-like portion to move in the direction of being inserted into the insertion path, while the belt-like portion is The movement in the direction of being pulled out from the insertion path is prevented. Therefore, with such a sealing band, although the ring-shaped band-shaped part can be narrowed to reduce the ring diameter, the band-shaped part cannot be loosened to increase the ring diameter. Therefore, if the sealing band is attached to the sealing object and is squeezed to the state where the diameter of the ring becomes the smallest, the ring cannot be loosened without breaking.

また、この封緘バンドにおいて、挿通部が有する第一部分には凹部が形成され、この凹部の開口は、帯状部が挿通路に挿通された際に、帯状部及び第二部分の双方によって形成される二重の隔壁によって塞がれる。したがって、帯状部のみによって形成される単一(一重)の隔壁で凹部の開口を塞いでいた従来品とは異なり、開口内にある帯状部は第二部分によって覆い隠されるので、開口内にある帯状部に対して何らかの治具を押し当てることはできなくなる。   Further, in this sealing band, a concave portion is formed in the first portion of the insertion portion, and the opening of the concave portion is formed by both the strip portion and the second portion when the strip portion is inserted through the insertion passage. It is blocked by a double bulkhead. Therefore, unlike the conventional product in which the opening of the concave portion is closed with a single (single) partition wall formed only by the belt-shaped portion, the belt-shaped portion in the opening is covered by the second portion, and thus is in the opening. Any jig cannot be pressed against the belt-like portion.

したがって、開口内で帯状部を変形させたり、そのような変形に伴って爪を変位させたりする不正な操作はできなくなるので、そのような不正な操作によって封緘を解くことはできず、従来品以上に封緘性能を高くすることができる。   Accordingly, since it is impossible to perform an unauthorized operation of deforming the belt-shaped portion within the opening or displacing the nail along with such a deformation, the seal cannot be released by such an unauthorized operation. The sealing performance can be increased as described above.

なお、以上説明した封緘バンドは、さらに、以下のような構成を備えていると好ましい。
まず、前記第一部分には、前記開口、前記第一貫通孔、及び前記第二貫通孔以外に、前記凹部の内側と外側とを連通させる第三貫通孔が形成されており、前記第二部分は、前記第一部分に対して取り付けられた際に、前記開口に加えて、前記第三貫通孔を塞ぐ形状とされていると好ましい。
In addition, it is preferable that the sealing band demonstrated above is further provided with the following structures.
First, in addition to the opening, the first through-hole, and the second through-hole, the first part is formed with a third through-hole that communicates the inside and the outside of the recess, and the second part Is preferably configured to close the third through hole in addition to the opening when attached to the first portion.

このように構成された封緘バンドによれば、第二部分が第一部分に対して取り付けられた際、第二部分は、前記開口に加えて、第三貫通孔を塞ぐ状態になる。そのため、仮に第二部分が存在しなければ、第三貫通孔を介して針先などを侵入させた場合に、その針先が爪に到達し得るような構造になっていたとしても、そのような針先の侵入を第二部分によって阻止でき、不正な操作に対する耐性をより一層高めることができる。   According to the sealing band configured as described above, when the second portion is attached to the first portion, the second portion is in a state of closing the third through hole in addition to the opening. Therefore, if the second part does not exist, even if the needle tip or the like is allowed to enter through the third through hole, even if the needle tip can reach the nail, it does not Intrusion of a sharp needle tip can be prevented by the second portion, and resistance to unauthorized operation can be further enhanced.

なお、第一部分に第三貫通孔が存在する場合、上述の通り、第二部分が第三貫通孔を塞ぐ構造になっている方が好ましいが、第三貫通孔の位置や大きさによっては、第二部分が第三貫通孔を塞がない構造になっていても特に問題がない場合もある。したがって、第三貫通孔が存在する場合でも、第二部分が第三貫通孔を塞ぐか否かは任意である。   In addition, when the third through hole is present in the first part, as described above, it is preferable that the second part has a structure blocking the third through hole, but depending on the position and size of the third through hole, There may be no particular problem even if the second portion has a structure that does not block the third through hole. Therefore, even when the third through hole exists, it is arbitrary whether or not the second portion blocks the third through hole.

また、前記第二部分には、当該第二部分を貫通する第四貫通孔が形成されており、前記帯状部が前記挿通路に挿通される際には、前記帯状部が前記第四貫通孔に挿通された状態とされ、当該状態とされた前記帯状部により、前記第二部分が前記第一部分から取り外される方向へ変位するのを阻止してあると好ましい。   The second part has a fourth through-hole penetrating the second part. When the belt-like part is inserted through the insertion passage, the belt-like part is the fourth through-hole. It is preferable that the second portion is prevented from being displaced in the direction of being removed from the first portion by the strip-shaped portion that is inserted into the first portion.

このように構成された封緘バンドによれば、帯状部が挿通路に挿通される際、帯状部が第四貫通孔に挿通された状態とされ、これにより、帯状部は、第二部分が第一部分から取り外される方向へ変位するのを阻止する。したがって、他のロック機構を採用することなく、帯状部と第四貫通孔によって第二部分が第一部分から取り外されないようにすることができ、他のロック機構が存在する場合よりも、封緘バンドの構造を簡素化することができる。   According to the sealing band configured as described above, when the band-shaped portion is inserted into the insertion passage, the band-shaped portion is inserted into the fourth through hole. Prevent displacement in the direction of removal from the part. Accordingly, the second portion can be prevented from being removed from the first portion by the belt-like portion and the fourth through hole without employing another lock mechanism, and the sealing band can be used as compared with the case where another lock mechanism is present. The structure can be simplified.

また、前記挿通部は、前記第一部分と前記第二部分とを連結するヒンジ部を有し、前記第一部分、前記第二部分、及び前記ヒンジ部が、樹脂材料によって一体成形されていると好ましい。   The insertion portion preferably includes a hinge portion that connects the first portion and the second portion, and the first portion, the second portion, and the hinge portion are preferably integrally formed of a resin material. .

このように構成された封緘バンドによれば、第一部分と第二部分がヒンジ部を介して連結されている。そのため、このようなヒンジ部が設けられていない場合とは異なり、第一部分と第二部分がバラバラにならず、一方だけを紛失したり、作業時に落としたりするの防ぐことができるので、封緘バンドを取り扱いやすくすることができる。   According to the sealing band configured as described above, the first portion and the second portion are connected via the hinge portion. Therefore, unlike the case where such a hinge part is not provided, the first part and the second part do not fall apart, and only one of them can be prevented from being lost or dropped during work. Can be handled easily.

また、前記第二部分は、前記第一部分に対して取り付けられた際に、前記開口を塞ぐ状態になる板状部を有し、当該板状部には、当該板状部の板厚方向に交差する方向へ突出する嵌合部が設けられ、当該嵌合部を前記第一部分に形成された被嵌合部に嵌合させることにより、前記板状部が前記開口から離間する方向へ捲れ上がるのを阻止してあると好ましい。   The second portion has a plate-like portion that closes the opening when attached to the first portion, and the plate-like portion has a plate-like direction in the plate-like portion. A fitting portion that protrudes in the intersecting direction is provided, and the plate-like portion is rolled up in a direction away from the opening by fitting the fitting portion to a fitted portion formed in the first portion. It is preferable to prevent this.

このように構成された封緘バンドによれば、第二部分が有する板状部には、上述のような嵌合部が設けられ、その嵌合部を第一部分が有する被嵌合部に嵌合させることにより、板状部が開口から離間する方向へ捲れ上がるのを阻止してある。したがって、このような嵌合部相当の部分が設けられていない場合とは異なり、板状部で開口を塞ぐ構造としてあるにもかかわらず、板状部が不正な操作を受けて捲れ上がる方向へ変形させられることがなく、不正な操作に対する耐性を高めることができる。   According to the sealing band configured as described above, the plate-like portion of the second portion is provided with the fitting portion as described above, and the fitting portion is fitted to the fitting portion of the first portion. By doing so, the plate-like portion is prevented from rolling up in a direction away from the opening. Therefore, unlike the case where such a portion corresponding to the fitting portion is not provided, the plate-like portion is subjected to an unauthorized operation in a direction in which the plate-like portion is swollen up even though the opening is blocked by the plate-like portion. Without being deformed, it is possible to increase resistance to unauthorized operations.

In the following description, with reference to the six views shown in FIGS. 1 (A) to 1 (F), the direction in which the portion appearing in the plan view is directed upward, and the portion appearing in the left side view is directed. The left direction, the direction where the part appearing in the front view is directed forward, the direction where the part appearing in the right side view is directed right, the direction where the part appearing in the rear view is directed is shown, and the bottom view appears The direction in which the location is directed is referred to as down. Further, as necessary, the respective directions of up, down, left, and right, front and rear are also shown in some of the drawings, and explanations will be made using these directions. However, each of these directions is only a direction defined for concisely explaining the relative positional relationship of each part constituting the sealing band, and in what direction the sealing band is used when the sealing band is used. It is optional to be directed.

[封緘バンドの構成]
封緘バンド1は、図1(A)〜図1(F)に示すように、帯状部3と、帯状部3の一端(図中下端)に設けられた挿通部5と、挿通部5に連結されたタグ7とを備える。これらはポリアミド、ポリエチレンなどの樹脂材料によって一体成形されている。
[Configuration of sealing band]
As shown in FIGS. 1A to 1F, the sealing band 1 is connected to the band-shaped portion 3, an insertion portion 5 provided at one end (lower end in the drawing) of the band-shaped portion 3, and the insertion portion 5. The tag 7 is provided. These are integrally formed of a resin material such as polyamide or polyethylene.

挿通部5は、図2(A)〜図2(F)に拡大して示すように、第一部分5Aと、第二部分5Bとを有し、これらがヒンジ部5Cを介して連結された構造になっている。第二部分5Bは、ヒンジ部5Cを変形させつつ、第一部分5Aに対して相対的に変位可能で、具体的には、図3(A)に示す第一位置から、図3(B)及び図3(C)に示す第二位置へ変位可能とされている。   The insertion part 5 has a first part 5A and a second part 5B as shown in an enlarged view in FIGS. 2A to 2F, and these are connected via a hinge part 5C. It has become. The second portion 5B can be displaced relative to the first portion 5A while deforming the hinge portion 5C. Specifically, from the first position shown in FIG. It can be displaced to the second position shown in FIG.

第二部分5Bが第一位置にある状態(図3(A)参照。)は、第二部分5Bが第一部分5Aから取り外された状態であり、これは封緘バンド1の成形直後の初期状態でもある。一方、第二部分5Bが第二位置にある状態(図3(B)及び図3(C)参照。)は、第二部分5Bが第一部分5Aに取り付けられた状態であり、これは封緘バンド1を使用するときの状態である。   The state in which the second portion 5B is in the first position (see FIG. 3A) is a state in which the second portion 5B is removed from the first portion 5A. This is the initial state immediately after the molding of the sealing band 1. is there. On the other hand, the state in which the second portion 5B is in the second position (see FIGS. 3B and 3C) is a state in which the second portion 5B is attached to the first portion 5A, which is a sealing band. This is the state when 1 is used.

第一部分5Aには係合突起11Aが設けられ、第二部分5Bには被係合部11Bが設けられている。第二部分5Bを第二位置に変位させた際には、係合突起11Aが被係合部11Bに引っかかることで、第二部分5Bが第一部分5Aに対して固定される。   The first portion 5A is provided with an engaging protrusion 11A, and the second portion 5B is provided with an engaged portion 11B. When the second portion 5B is displaced to the second position, the second portion 5B is fixed to the first portion 5A by the engaging protrusion 11A being caught by the engaged portion 11B.

第二部分5Bは、第二部分5Bが第二位置にある場合に(図3(B)及び図3(C)参照。)、第一部分5Aの正面側を覆う状態になる正面カバー部13Aと、第一部分5Aの底面側を覆う状態になる底面カバー部13Bとを有する。   The second portion 5B includes a front cover portion 13A that covers the front side of the first portion 5A when the second portion 5B is in the second position (see FIGS. 3B and 3C). And a bottom surface cover portion 13B that covers the bottom surface side of the first portion 5A.

底面カバー部13Bは、図中上下方向が板厚方向となる板状に形成されている(本明細書でいう板状部の一例に相当。)。底面カバー部13Bには、その板厚方向に交差する方向へ突出する嵌合部15Aが設けられている。この嵌合部15Aは、図4(A)及び図4(B)に示すように、第二部分5Bが第二位置にある場合に、第一部分5A側に設けられた被嵌合部15Bに嵌合する。   The bottom cover portion 13B is formed in a plate shape whose vertical direction in the drawing is the plate thickness direction (corresponding to an example of a plate-like portion in the present specification). The bottom cover portion 13B is provided with a fitting portion 15A that protrudes in a direction intersecting the plate thickness direction. As shown in FIGS. 4A and 4B, the fitting portion 15A is formed on the fitted portion 15B provided on the first portion 5A side when the second portion 5B is in the second position. Mating.

第一部分5Aは、図2(A)〜図2(F)に示すように、第一部分5Aの前側、左側、後側、右側、それぞれを構成する周壁部17A,17B,17C,17D、上側を構成する天井部17E、及び下側を構成する底部17Fを有する。これら周壁部17A,17B,17C,17D、天井部17E、及び底部17Fは、これらによって囲まれる内部空間を形成しており、その内部空間は底部17Fに形成された略四角形の開口19Aを介して外部に連通している。これらの構成により、第一部分5Aは、上向きに凹む凹部19を有する形状となっている。   As shown in FIGS. 2 (A) to 2 (F), the first portion 5A includes the peripheral wall portions 17A, 17B, 17C, and 17D that constitute the front side, the left side, the rear side, and the right side of the first portion 5A. It has a ceiling portion 17E that constitutes and a bottom portion 17F that constitutes the lower side. The peripheral wall portions 17A, 17B, 17C, 17D, the ceiling portion 17E, and the bottom portion 17F form an internal space surrounded by them, and the internal space is formed through a substantially rectangular opening 19A formed in the bottom portion 17F. It communicates with the outside. With these configurations, the first portion 5A has a shape having a concave portion 19 that is recessed upward.

凹部19を挟んで対向する周壁部17A,17Cには、図中前後方向に貫通する第一貫通孔21、及び第二貫通孔22が形成されている。また、周壁部17Aには、図中前後方向に貫通する第三貫通孔23が形成され、第二部分5Bには、図中前後方向に貫通する第四貫通孔24が形成されている。   A first through hole 21 and a second through hole 22 that penetrate in the front-rear direction in the figure are formed in the peripheral wall portions 17A and 17C that face each other with the concave portion 19 in between. Further, a third through hole 23 that penetrates in the front-rear direction in the figure is formed in the peripheral wall portion 17A, and a fourth through hole 24 that penetrates in the front-rear direction in the figure is formed in the second portion 5B.

第二部分5Bが第二位置にある場合、図4(B)に示すように、第一部分5Aの図中前側にある第三貫通孔23は、第二部分5Bの正面カバー部13Aによって覆い隠される。また、第二部分5Bが第二位置にある場合、第一部分5Aの図中下側にある開口19Aは、第二部分5Bの底面カバー部13Bによって覆い隠される。一方、第二部分5Bが第二位置にある場合、第一貫通孔21、第二貫通孔22、及び第四貫通孔24は、直列に並ぶ位置にあり、挿通部5には、第四貫通孔24から第一貫通孔21及び凹部19内を経て第二貫通孔22に至る挿通路25が形成される。   When the second portion 5B is in the second position, as shown in FIG. 4B, the third through hole 23 on the front side in the drawing of the first portion 5A is covered by the front cover portion 13A of the second portion 5B. It is. When the second portion 5B is in the second position, the opening 19A on the lower side of the first portion 5A in the figure is covered by the bottom surface cover portion 13B of the second portion 5B. On the other hand, when the second portion 5B is in the second position, the first through hole 21, the second through hole 22, and the fourth through hole 24 are in a position aligned in series. An insertion passage 25 extending from the hole 24 to the second through hole 22 through the first through hole 21 and the recess 19 is formed.

第一部分5Aにおいて、凹部19の内側には、爪26が設けられている。より詳しくは、凹部19の内側には、図4(B)及び図5(B)に示すように、周壁部17Aの上端から図中後方に向かって延設されるとともに、図中左右両端は周壁部17B,17Dに連設された板状支持部28が形成されている。上述の爪26は、板状支持部28から図中後方及び下方に向かって突設されている。爪26に外力が加えられた際には、爪26ないし板状支持部28が弾性変形し、これにより、爪26が上下方向に変位する。   In the first part 5 </ b> A, a claw 26 is provided inside the recess 19. More specifically, as shown in FIGS. 4B and 5B, the recess 19 extends from the upper end of the peripheral wall portion 17A toward the rear in the drawing, and the left and right ends in the drawing are A plate-like support portion 28 connected to the peripheral wall portions 17B and 17D is formed. The above-mentioned claw 26 protrudes from the plate-like support portion 28 toward the rear and the lower side in the figure. When an external force is applied to the claw 26, the claw 26 or the plate-like support portion 28 is elastically deformed, whereby the claw 26 is displaced in the vertical direction.

帯状部3の正面側には、図1(C)に示すように、帯状部3の長手方向に沿って複数の歯31が列設されている。帯状部3は、図5(A)及び図5(B)に示すように、挿通部5が設けられた一端とは反対側の他端側から挿通路25へ挿し込むことができる。このとき、挿通部5の爪26は帯状部3の歯31に引っかかり、これら複数の歯31及び爪26によってラチェット機構が構成される。   As shown in FIG. 1C, a plurality of teeth 31 are arranged along the longitudinal direction of the band-like part 3 on the front side of the band-like part 3. As shown in FIGS. 5 (A) and 5 (B), the belt-like portion 3 can be inserted into the insertion passage 25 from the other end side opposite to the one end where the insertion portion 5 is provided. At this time, the claw 26 of the insertion portion 5 is caught by the teeth 31 of the band-shaped portion 3, and the ratchet mechanism is configured by the plurality of teeth 31 and the claw 26.

このラチェット機構は、帯状部3が挿通路25へ挿し込まれる方向へ移動することを許容する一方、帯状部3が挿通路25から引き抜かれる方向へ移動することを阻止する状態にある。具体的には、帯状部3が挿通路25へ挿し込まれる方向へ移動する場合、爪26の変位方向、歯31の移動方向、及び爪26と歯31との当接面の傾きは、歯31が爪26を押圧したときに、その分力が爪26を上方へと変位させるような関係に設定されている。そのため、歯31から押圧された爪26は、歯31から外れる方向へと逃げ、その結果、帯状部3の移動は許容されることになる。一方、帯状部3が挿通路25から引き抜かれる方向へ移動する場合、爪26の変位方向、歯31の移動方向、及び爪26と歯31との当接面の傾きは、歯31が爪26を押圧したときに、その分力が爪26を上方へは変位させないような関係に設定されている。そのため、歯31から押圧された爪26は、少なくとも上方へは変位せず、その結果、帯状部3の移動を阻止されることになる。   This ratchet mechanism is in a state in which the belt-like portion 3 is allowed to move in the direction of being inserted into the insertion passage 25 while the belt-like portion 3 is prevented from moving in the direction of being pulled out of the insertion passage 25. Specifically, when the belt-like portion 3 moves in the direction of insertion into the insertion passage 25, the displacement direction of the claw 26, the movement direction of the teeth 31, and the inclination of the contact surface between the claw 26 and the teeth 31 are When 31 pushes the nail | claw 26, the component force is set to the relationship which displaces the nail | claw 26 upwards. Therefore, the nail | claw 26 pressed from the tooth | gear 31 escapes in the direction which remove | deviates from the tooth | gear 31, and, as a result, the movement of the strip | belt-shaped part 3 is accept | permitted. On the other hand, when the belt-like portion 3 moves in the direction in which it is pulled out from the insertion passage 25, the displacement direction of the claw 26, the movement direction of the tooth 31, and the inclination of the contact surface between the claw 26 and the tooth 31 are as follows. Is set such that the component force does not displace the claw 26 upward. Therefore, the nail | claw 26 pressed from the tooth | gear 31 does not displace at least upwards, As a result, the movement of the strip | belt-shaped part 3 is prevented.

[効果]
以上のように構成された封緘バンド1によれば、帯状部3の一端に設けられた挿通部5が有する挿通路25に対し、帯状部3を他端側から挿し込むと、帯状部3が環状になる。このとき、帯状部3が有する複数の歯31と挿通部5が有する爪26が上述のようなラチェット機構を構成する。そのため、このような封緘バンド1であれば、環状になった帯状部3を絞って環の径を小さくすることはできても、帯状部3を緩めて環の径を大きくすることはできない。したがって、封緘バンド1を封緘対象物に取り付けて、環の径が最も小さくなる状態まで絞れば、その環を破断することなく可逆的に緩めることはできなくなる。よって、このような封緘バンド1で開封されては困る箇所を封止すれば、当該箇所が秘密裏に開封されるのを防ぐことができ、万一、封緘バンド1が破断を伴って開封されたとしても、開封されたという事実を直ちに把握することができる。
[effect]
According to the sealing band 1 configured as described above, when the band 3 is inserted from the other end side into the insertion path 25 of the insertion part 5 provided at one end of the band 3, the band 3 is It becomes a ring. At this time, the plurality of teeth 31 included in the belt-shaped portion 3 and the claw 26 included in the insertion portion 5 constitute a ratchet mechanism as described above. Therefore, with such a sealing band 1, the ring-shaped band 3 can be narrowed to reduce the diameter of the ring, but the band-shaped part 3 cannot be loosened to increase the diameter of the ring. Therefore, if the sealing band 1 is attached to the sealing object and is squeezed to a state where the diameter of the ring becomes the smallest, the ring cannot be reversibly loosened without breaking. Therefore, if a portion that is troublesome to be opened with such a sealing band 1 is sealed, it is possible to prevent the portion from being opened secretly, and by any chance the sealing band 1 is opened with a break. Even so, the fact that it was opened can be immediately grasped.

また、上記封緘バンド1において、帯状部3が挿通路25に挿通された際には、帯状部3及び第二部分5Bの双方によって二重の隔壁が形成され、この二重の隔壁によって凹部19の開口19Aが塞がれる。そのため、開口19Aに何らかの治具を挿し込んで爪26を動かすような不正な操作をしようとしても、爪26を直接押圧することができないのはもちろんのこと、爪26が当接している帯状部3を押圧することもできない。したがって、帯状部3を強く押圧して、変形する帯状部3とともに爪26を変位させる、といった不正な操作を行うことはできず、凹部19相当部分の開口を帯状部3相当物によって形成される単一の隔壁で塞いでいた従来品に比べ、封緘性能を高くすることができる。よって、例えば金型の都合で、どうしても開口19A相当の形状が生じてしまう場合には、このような構成を採用すると有効である。   In the sealing band 1, when the strip 3 is inserted through the insertion passage 25, a double partition is formed by both the strip 3 and the second portion 5 </ b> B, and the recess 19 is formed by the double partition. The opening 19A is closed. For this reason, even if an illegal operation such as inserting some jig into the opening 19A and moving the claw 26 is attempted, the claw 26 cannot be pressed directly, and the belt-like portion with which the claw 26 is in contact 3 cannot be pressed. Accordingly, it is not possible to perform an unauthorized operation of pressing the belt-shaped portion 3 strongly and displacing the claw 26 together with the deformed belt-shaped portion 3, and the opening corresponding to the concave portion 19 is formed by the belt-shaped portion 3 equivalent. The sealing performance can be improved as compared with the conventional product which is closed with a single partition. Therefore, for example, when the shape corresponding to the opening 19A is inevitably generated due to the convenience of the mold, it is effective to adopt such a configuration.

また、上記封緘バンド1の場合、第二部分5Bは、開口19Aに加えて、第三貫通孔23を塞ぐ状態になる。そのため、仮に第二部分5Bが存在しなければ、第三貫通孔23を介して針先などを侵入させた場合に、その針先が爪26に到達し得るような構造になっていたとしても、そのような針先の侵入を第二部分5Bによって阻止でき、不正な操作に対する耐性をより一層高めることができる。したがって、例えば金型の都合で、どうしても第三貫通孔23相当の形状が生じてしまう場合には、このような構成を採用すると有効である。   In the case of the sealing band 1, the second portion 5B is in a state of closing the third through hole 23 in addition to the opening 19A. Therefore, even if the second portion 5B does not exist, even if the needle tip or the like is allowed to enter through the third through hole 23, the needle tip may reach the claw 26. Such intrusion of the needle tip can be prevented by the second portion 5B, and resistance to unauthorized operation can be further enhanced. Therefore, for example, when the shape corresponding to the third through hole 23 is inevitably generated due to the convenience of the mold, it is effective to adopt such a configuration.

また、上記封緘バンド1によれば、帯状部3が挿通路25に挿通される際には、帯状部3が第四貫通孔24に挿通された状態とされるので、これにより、帯状部3は、第二部分5Bが第一部分5Aから取り外される方向へ変位するのを阻止する部材としても機能する。したがって、このような第四貫通孔24が設けられていれば、他のロック機構を採用することなく、帯状部3と第四貫通孔24によって第二部分5Bが第一部分5Aから取り外されないようにすることができ、他のロック機構が存在する場合よりも、封緘バンド1の構造を簡素化することができる。   Further, according to the sealing band 1, when the strip 3 is inserted through the insertion passage 25, the strip 3 is inserted into the fourth through hole 24. Also functions as a member that prevents the second portion 5B from being displaced in the direction of being removed from the first portion 5A. Therefore, if such a fourth through hole 24 is provided, the second portion 5B is not removed from the first portion 5A by the belt-like portion 3 and the fourth through hole 24 without adopting another locking mechanism. The structure of the sealing band 1 can be simplified as compared with the case where other locking mechanisms are present.

また、上記封緘バンド1によれば、第一部分5Aと第二部分5Bがヒンジ部5Cを介して連結されているので、第一部分5Aと第二部分5Bがバラバラにならず、一方だけを紛失したり、作業時に落としたりするのを防ぐことができ、封緘バンド1を取り扱いやすくすることができる。   Further, according to the sealing band 1, since the first portion 5A and the second portion 5B are connected via the hinge portion 5C, the first portion 5A and the second portion 5B do not fall apart, and only one of them is lost. Or can be prevented from being dropped during work, and the sealing band 1 can be easily handled.

また、上記封緘バンド1によれば、底面カバー部13Bに設けられた嵌合部15Aを、第一部分5Aが有する被嵌合部15Bに嵌合させて、底面カバー部13Bが開口19Aから離間する方向(図中下方)へ捲れ上がるのを阻止してある。したがって、このような嵌合部15A相当の部分が設けられていない場合とは異なり、底面カバー部13Bが不正な操作を受けて下方へ捲れ上がることがなく、この点でも不正な操作に対する耐性を高めることができる。   Further, according to the sealing band 1, the bottom cover portion 13B is separated from the opening 19A by fitting the fitting portion 15A provided on the bottom surface cover portion 13B with the fitted portion 15B included in the first portion 5A. It is prevented from climbing in the direction (downward in the figure). Therefore, unlike the case where such a portion corresponding to the fitting portion 15A is not provided, the bottom surface cover portion 13B does not squeeze downward due to an unauthorized operation, and in this respect as well, it is resistant to unauthorized operations. Can be increased.

[その他の事例]
以上、封緘バンドについて、具体的な事例を挙げて説明したが、本発明は上述の具体的事例に限定されるものではなく、本発明の技術的思想を逸脱しない範囲内において、種々の形態で実施することができる。
[Other cases]
The sealing band has been described with specific examples, but the present invention is not limited to the specific examples described above, and various forms are possible without departing from the technical idea of the present invention. Can be implemented.

例えば、上記事例では、第二部分5Bによって第三貫通孔23を塞ぐ構造を採用していたが、第三貫通孔23の位置や大きさによっては、第三貫通孔23を塞がなくても不正な操作がなされない可能性もある。したがって、そのような場合、第三貫通孔23を塞ぐ構造を採用するか否かは任意である。   For example, in the above example, the structure in which the third through hole 23 is blocked by the second portion 5B is employed. However, depending on the position and size of the third through hole 23, the third through hole 23 may not be blocked. There is a possibility that an illegal operation is not performed. Therefore, in such a case, whether or not to adopt a structure for closing the third through hole 23 is arbitrary.
