Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that to use conventional various kinds of sealing tools is hard due to a concern in using as a sealing tool since removing it intentionally is possible, while they are widely used for fixing a brand tag or a price tag or for bundling an electric wire or the like since workability at looping and the function in terms of reverse stop are excellent. <P>SOLUTION: The sealing tool has a structure that a tamper proof part covering around a securing head part is arranged so that a tampering at the securing part of a beltlike part and a lock part can be prevented and also a beltlike part is arranged extendedly from the tamper proof part and further the securing head part and the tamper proof part are connected as the connection can be destroyed with a small external force. Thus, tampering becomes hard and also a sealing can be removed with a small external force and further since the securing head remains on the beltlike part, a trace can be checked clearly when the sealing is removed and reuse of the tool becomes impossible. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a sealing tool used when sealing various bags, various boxes, and the like mainly requiring security.

As for bags and boxes that require security, specifically, for example, bags and boxes for cash transport and mail, recently, synthetic resin sealing tools have been attracting attention.
The reason is that the mouth of the bag and the box body and lid can be easily bundled and workability is good, and most of the seals are simple in structure and can be molded integrally with synthetic resin. This is because mass production is possible and can be provided at low cost.
The conventional sealing device introduced here has a shape that is close to a straight line when not in use, and can be formed into a loop shape by simply inserting it at the time of use. So far, it is mainly used when attaching brand tags and price tags to products, or mainly used for binding electric wires etc. For the above reasons, Recently, this type of sealing tool has begun to attract attention as a sealing material.
The above-mentioned sealing tools have been used in large quantities and are technically close to the completed area, so there has been no problem in conventional applications. However, when used as a sealing tool, the problem still remains unsolved. There are still problems to be solved.

For example, the case where the connecting member disclosed in Japanese Patent Publication No. 46-11373 is used as a sealing tool will be described as an example. As shown in FIGS. While a plurality of portions 11b and small linear portions 11a are alternately provided, the lock portion 12b of the locking head 12 is formed as a plurality of hollow collet-like flexible claws 12c, and the flexible claws 12c are formed in the large size. When the portion 11b passes through the hollow portion 12a, it spreads outward and forwards the belt-like portion 11, and when the small portion 11a passes, it returns to its original position by its own elastic force, and the reverse of the belt-like portion 11 I try to prevent sending.

16 to 17, when the belt-like portion 11 is inserted into the locking head 12, the flexible claw 12c of the lock portion 12b is moved from the solid line position in FIG. The large deflection part 11b is passed. Thereafter, when the small portion 11a reaches the passing position, the flexible claw 12c returns to the original position by its own elastic force. By repeating the above operation when the belt-like portion 11 is inserted into the locking head 12 until the loop diameter of the belt-like portion 11 reaches the desired diameter in this way, the conical bottom surface of the large-shaped portion 11b becomes the flexible claw 12c. Since the band-like portion 1 cannot be moved in the direction opposite to the insertion direction by interfering with the distal end portion of the sheet, sealing workability is good.

On the other hand, the sealing device described in Japanese Patent Publication No. 57-8473 is representative of the sealing devices disclosed in Japanese Patent Publication No. 57-8473, Japanese Patent Publication No. 60-36588, and Japanese Patent Publication No. 56-16294. Explaining the problem, in FIGS. 18 to 19, the band-shaped portion 21 is formed in the shape of a filament 21 a, and an arrowhead-shaped coupling portion 21 b having blades 21 c that can be reduced and enlarged is formed on the free end side of the band-shaped portion 21. Provided. On the other hand, the locking portion 22b of the locking head 22 is a fixed tooth 22c having a hole 22a that is smaller than the outer dimension when the coupling portion 21b is enlarged and larger than the outer dimension when the coupling portion 21b is reduced.

  That is, when the coupling portion 21b is inserted into the hole 22a, the blade 21c of the coupling portion 21b contracts to the imaginary line position shown in FIG. 19 and the blade 21c returns to the original position when the blade 21c passes through the hole 22a. Since the fixed teeth 22c prevent the return, the workability is good and can be used for temporary sealing.

Further, when the binding band disclosed in Japanese Utility Model Publication No. 51-47579 is used as a sealing tool, sawtooth teeth 51b are formed on the belt-like portion 51 as shown in FIGS. On the other hand, the lock portion 52b facing the insertion hole 52a of the locking head 52 is formed into a swingable claw 52c shape, and this claw 52c portion is opposed to the serrated teeth 51b of the belt-like portion 51 passing through the insertion hole 52c. Since it is formed so as to be disengaged from the serrated teeth 51b in one direction and to prevent the movement of the band-like portion 51 in the opposite direction, the band-like portion 51 is simply inserted into the engaging head 52. Since it becomes a loop shape and the belt-like portion 51 cannot be removed from the engagement head 52 unless a large force is applied, the workability is good and it seems that it can be used as a sealed glance.

  However, in the sealing device disclosed in Japanese Patent Publication No. 46-11373, since the flexible claw 12c of the lock portion 12b is exposed, the flexible claw 12c is opened like a virtual line as shown in FIG. Since the belt-like portion 11 can be moved in the direction opposite to the insertion direction, there remains a certain amount of anxiety when used as a sealing tool. In addition, the belt-like portion 11 is generally known to have a high tensile strength because the small portion 11a is stretched and molecularly oriented. However, when forcibly releasing the sealing, the conical bottom portion of the large portion 11b is used. As a result, the tip of the flexible claw 12c is deformed into an R shape, and the belt-like portion 11 is removed from the locking head portion 12 so that it can be reused.

Further, as in the previous example, the sealing tool disclosed in Japanese Patent Publication No. 57-8473 is not impossible to release the sealing if the blade 21c is contracted with tweezers or the like.
In many cases of this type of sealing tool, when an external force is applied in the direction opposite to the insertion direction of the coupling portion 21b in FIG. 19, the blade 21c is inverted in the distal direction of the coupling portion 21b and is squeezed by the hole 22a. It pulls out from the hole 22a while drawing in a thread shape. Since this thread-like blade 21c is re-sealed, it is sandwiched between the tip of the coupling portion 21b and the hole 22a and is press-fitted, so that the heel is the same as when an unused sealing tool is inserted for the first time. There is a risk of not being noticed even if tampered.

Further, when the binding band disclosed in Japanese Utility Model Publication No. 51-47579 is used as a sealing tool, when a thin plate-like piece B is inserted as shown in FIG. Since the engagement with the tooth 51 is released and swings from a thick solid line position to a thin imaginary line position, the band-like part 51 can be removed from the engaging head 52, which is completely different from the case of using an unused product. It can be reused in the same state.
Thus, in order to use this type of device as a sealing tool, anxiety remains as in the previous example.
Since the various conventional sealing devices described above are excellent in workability in the case of making a loop shape and functions from the viewpoint of the check effect, as described at the beginning, Despite being widely used for bundling electric wires and the like, in any case, there remains a problem that it is difficult to use as a sealing tool for the reasons described above.

  Therefore, the present invention aims to provide a sealing device that is difficult to tamper with and can be easily unsealed with a small external force. Further, another object is to utilize the mechanisms of various conventional sealing devices. The purpose of the present invention is to provide a sealing device that can make the most of its superiority.

In order to achieve the above object, the present invention solves the problem by using the following means.
That is, the locking head having an insertion hole, a band-shaped portion that passes through the insertion hole, and a locking portion that locks the band-shaped portion after passing the band-shaped portion through the insertion hole are provided in the locking head. A sealing tool, in which a tamper-proof portion is provided around the locking head to cover the locking portion between the band-shaped portion and the lock portion so as to prevent tampering. Further, the locking head and the tamper-proof portion are connected so that they can be broken with a small external force.

  In addition to the above configuration, the second problem-solving means forms the shape of the tamper-proof portion in a cylindrical shape that opens the axial direction of the insertion hole, while the size in the cylindrical axial direction is set to tamper with the lock portion. The structure is extended to the extent that it is difficult to peel.

The third problem solving means adds the following components to the two configurations.
That is, it is set as the structure which extended various accessory parts from the tampering prevention part.

  Furthermore, a 4th problem-solving means adds the component part which formed a part or all of the accessory part in flat form in the said structure.

  Further, the fifth problem solving means adds a component having an IC tag to the accessory part to the configuration of the second and fourth problem solving means.

  Sixth problem solving means is provided with a plurality of large portions and small portions alternately in the belt-like portion in the first to fifth problem solving means, respectively, and the locking portion of the locking head is formed with a hollow collet. When the large portion passes through the hollow portion, the flexible claw spreads outward to advance the belt-like portion, and when the small portion passes, it has its own elastic force. To return to the original position and add a component to prevent reverse feeding of the belt-like portion.

  The seventh problem-solving means is the first to fifth problem-solving means, in which each of the band-shaped portions is formed in a filament shape, and on the free end side of the band-shaped portion, an arrowhead-shaped coupling portion that can be reduced and enlarged is provided. On the other hand, a component portion is added in which the locking portion of the locking head is a fixed tooth having a hole that is smaller than the outer dimension at the time of expansion of the coupling portion and larger than the outer dimension at the time of reduction.

  The eighth problem-solving means is the first to fifth problem-solving means, each of which forms a band-like portion in the form of a filament, and on the free end side of the band-like portion, an arrowhead-like coupling portion that can be reduced and enlarged is provided. The intermediate part of the filament is folded in half, while the locking part of the locking head is smaller than the outer dimension when the coupling part is enlarged and larger than the outer dimension when the joint is reduced. Add a fixed tooth component with.

  The ninth problem-solving means is the same as the first to fifth problem-solving means, in which each of the band-shaped portions is formed in a filament shape and an arrowhead-shaped coupling portion is provided on the free end side of the band-shaped portion. The lock part of the stop head is formed in an insertion hole shape that can be reduced and enlarged, and this lock part is smaller than the outer dimension of the coupling part when reduced and larger than the outer dimension of the coupling part when enlarged. Add components.

  The tenth problem-solving means, in each of the first to fifth problem-solving means, is to form a band-shaped portion in the form of a filament, and at the free end side of this band-shaped portion, provide an arrowhead-shaped coupling portion, While the intermediate part of the filament is folded in half, the locking part of the locking head is formed in an insertion hole shape that can be reduced and enlarged, and this locking part is smaller than the outer dimensions of the coupling part when enlarged, and enlarged Occasionally, components that are larger than the outer dimensions of the joint are added.

  The eleventh problem-solving means is the same as the first to fifth problem-solving means, in which a serrated tooth is formed on the belt-shaped portion, while the locking portion of the locking head is formed with a swingable claw shape. The claw-shaped portion is disengaged from the serrated teeth in one direction, and a component formed to prevent movement of the belt-shaped portion in the opposite direction is added.

The operation of the first problem solving means is as follows.
That is, the band-shaped part is passed through the insertion hole of the locking head through the band-shaped part to form a loop, and the lock part on the locking head locks the band-shaped part. In this state, one loop is formed by the locking portion of the belt-shaped portion, the lock portion, the locking head, the connecting portion that can be broken with a small external force, the tamper-proof portion, and the belt-shaped portion.
Therefore, it is easy to operate because the loop is formed simply by passing the band-like part through the insertion hole of the locking head, and in addition to preventing tampering of the locking part between the band-like part and the lock part, in addition to removing the seal Only by applying a slight external force, the locking head can be detached from the tamper-preventing portion while the band-shaped portion and the locking head remain locked. In this case, since the locking head remains in the band-like portion, when the seal is released, the trace can be clearly confirmed and the reuse becomes impossible.

  In addition to the action of the first problem solving means, the action of the second problem solving means is formed in a cylindrical shape that opens the axial direction of the insertion hole, so that the mold is used. In that case, it can be easily manufactured.

  The action of the third problem solving means is not only the action of the first or second problem solving means, but also the accessory part can be held by hand, so that the seal can be easily opened, the contents of the sealed contents, and other tags It can be used for mounting of the seals and stabilizing the posture of the sealing tool itself, and the range of applications is widened.

  In addition to the action of the second problem solving means, the action of the fourth problem solving means can be easily held by hand because of the flat portion, and the sealed contents etc. can be easily displayed.

  In addition to the actions of the third or fourth problem solving means, the action by the fifth problem solving means is to disclose various information to the customer when the brand tag and the price tag are attached to the product by radio signal. In addition to barcodes that are currently mainstream, payment can be made in batches for multiple products, and it can be used as a sealing tool for product sales, as well as entry / exit, transit location, current location and seal The contents can be confirmed, and the traceability of the sealed articles becomes possible.

  The action of the sixth problem solving means includes the action of the first to fifth problem solving means, and when the belt-like portion is inserted into the locking head, the flexible claw of the lock portion is caused by the large cone portion. Bends and passes large part. Thereafter, when the small portion reaches the passing position, the flexible claw returns to the original position by its own elastic force. If the above-described operation is repeated until the loop diameter of the belt-like portion reaches the desired diameter in this manner, the cone bottom surface of the large portion interferes with the tip of the flexible claw. Since it is impossible to move the strip in the direction opposite to the insertion direction, the loop diameter can be freely selected, the workability can be improved, and the structure is simple and the synthetic resin is used. Can be integrally molded, and mass production is possible and can be provided at low cost.

  The action of the seventh problem solving means is in addition to the actions of the first to fifth problem solving means. When the connecting portion is inserted into the hole, the connecting portion shrinks and returns to the original position when it passes through the hole. In addition, since the fixed teeth prevent the reverse movement, the workability can be improved with a simple mechanism.

The action of the eighth problem solving means is in addition to the actions of the first to fifth problem solving means, and when the connecting portion is inserted into the hole, the connecting portion shrinks and returns to the original position when it passes through the hole. In addition, since the fixed teeth prevent the reverse movement, the workability can be improved with a simple mechanism.
Further, since the belt-shaped portion is folded in two, when the loop is formed, the bulge in the loop can be reduced, so that other articles or the like are less likely to enter the loop. As a result, entanglement between the sealing tool and other articles can be prevented.

The action of the ninth problem solving means is in addition to the actions of the first to fifth problem solving means, in addition to providing an arrowhead-like coupling portion on the free end side of the belt-like portion, and reducing the lock portion of the locking head The insertion hole of the lock part is formed to be smaller than the outer dimension of the coupling part when reduced, and larger than the outer dimension of the coupling part when enlarged. Yes.
Therefore, in order to tamper, it is necessary to widen the insertion hole, and it is more difficult to tamper than the sealing tool of the previous example.

The action of the tenth problem solving means is provided with an arrowhead-like coupling part on the free end side of the belt-like part in addition to the actions of the first to fifth problem solving means, and the lock part of the locking head is reduced. The insertion hole of the lock part is formed to be smaller than the outer dimension of the coupling part when reduced, and larger than the outer dimension of the coupling part when enlarged. Yes.
Therefore, in order to tamper, it is necessary to widen the insertion hole, and it is more difficult to tamper than the sealing tool of the previous example.
Further, since the belt-shaped portion is folded in two, when the loop is formed, the bulge in the loop can be reduced, so that other articles or the like are less likely to enter the loop. As a result, entanglement between the sealing tool and other articles can be prevented.

  The action of the eleventh problem solving means is in addition to the actions of the first to fifth problem solving means, in addition to forming serrated teeth on the belt-like part, while the lock part facing the insertion hole of the locking head The claw portion is opposed to the serrated tooth of the band-shaped portion passing through the insertion hole, and is disengaged from the saw-toothed tooth in one direction, and the band-shaped portion in the opposite direction. Therefore, it is possible to form a desired loop simply by inserting the required length into the engaging head, and further, if a large force is not applied, from the engaging head, Since the belt-shaped part does not come off, it is suitable for cases where strength is required, and it is suitable for a mouthpiece of a bag or the like, and has good workability.

  As described above, the present invention is not easily tampered with, and can be easily unsealed with a small external force. Further, since the locking head remains in the belt-like portion, the unsealing has been released. In this case, the trace can be clearly confirmed and reuse can be made impossible.

Next, embodiments of the present invention will be described in detail with reference to the drawings.
First, the drawings will be described. FIG. 1 is a partial cross-sectional view showing the first embodiment of the present invention, a part of which is omitted, FIG. 2 is a plan view thereof, and FIG. FIG. 4 is a plan view of FIG. 3, FIGS. 5 and 6 are explanatory views showing the use state of the sealing device of the present invention, and FIG. 7 is a second embodiment of the present invention. 8 is a partially omitted plan view, FIG. 8 is a front view partially cut away from FIG. 7, and FIG. 9 is a further development of the second embodiment of the present invention. FIG. 10 is a partially perspective view showing the third embodiment of the present invention, FIG. 11 is a front view showing a part of FIG. 12 is a partially omitted plan view showing a fourth embodiment of the present invention, FIG. 13 is a front view of FIG. 12 partially cut away and partially omitted, and FIG. The fifth Plan view partially omitted showing an embodiment, FIG. 15 is a front view partially omitted cross section of a part of FIG. 14.

The first embodiment will be described. In FIGS. 1 to 4, a strip-shaped portion 11 is provided with a large number of conical large portions 11 b and linear small portions 11 a alternately. The small portion 11a is initially made slightly thick and short, and is elongated while extending in the longitudinal direction while being molecularly oriented. The advantage of this stretching is that when injection molding is performed using a thermoplastic resin such as polyamide or polypropylene as the raw material, since the small portion 11a is thick at the beginning of molding, the resin has good fluidity and is easy to mold. In addition, after stretching, the tensile strength in the longitudinal direction of the band-like part 11 can be increased by molecular orientation, and the flexibility as the band-like part can be obtained weakly in the bending direction. The small portion 11a is desirably stretched in order to obtain the above-described advantages, but may be unstretched when strength and flexibility are not important.
On the other hand, the lock portion 12b of the locking head portion 12 includes a plurality of hollow collet-like flexible claws 12c. These flexible claws 12c are formed in the shape of a truncated cone in appearance, and the hollow portion 12a of the top portion 12d is smaller than the maximum size of the large portion 11b of the strip portion 11 and larger than the small portion 11a. Form to dimensions. Each flexible claw 12c is formed so as to be bent outwardly within an elastic limit, starting from the opposite side of the top 12d.
And each flexible nail | claw 12c spreads outside when the large-sized part 11b passes the hollow part 12a, and forwards the strip | belt-shaped part 11, and when the said small-sized part 11a passes, it is original with an own elastic force. Returning to the position prevents reverse feeding of the belt-like portion 11.
Now, a cylindrical tamper-proof portion 13 is provided around the locking head 12 formed as described above. The falsification preventing portion 13 is formed to extend above the top portion 12d to such an extent that it is difficult to spread the top portion 12d of each flexible claw 12c outward. Further, the falsification preventing portion 13 and the locking head portion 12 are connected by a thin connecting portion 14 that can be broken with a small external force. As shown in FIGS. 3 and 4, the connecting portion 14 may be a plurality of connections, or may be a single connection, or the gap between the tamper prevention portion and the locking head is connected with a thin burr-like film. Since the external force to be destroyed differs depending on the application, it may be determined according to the size.
The band-shaped portion 11 described above is extended from the tamper-proof portion 13 formed in this way.
Further, a flat plate-like display unit 15, which is an accessory unit, is extended from the falsification preventing unit 13 in the direction opposite to the extending direction of the belt-like portion. The display unit 15 is provided with an IC tag 16. The IC tag 16 is formed by forming an IC chip 16a, an antenna 16b, and the like on a plastic film, and wirelessly communicates with another antenna (not shown) and a reader / writer.
Such a sealing device of the first embodiment is integrally injection-molded using a thermoplastic resin such as polyamide or polypropylene as a raw material.

If the sealing tool comprised in this way is demonstrated, in FIG. 5, when the lid | cover Y is put on the box X which put the to-be-sealed thing which is not shown in figure, and these are sealed, for example, the strip | belt-shaped part 11 is box After passing through the holes X1 and Y1 of X and the lid Y, the belt-like portion 11 is passed through the hollow portion 12a of the locking head 12. And if the strip | belt-shaped part 11 is pulled, the large-sized part 11b of the strip | belt-shaped part 11 will spread each flexible nail | claw 12c outside and will pass the hollow part 12a. Next, when the small portion 11a reaches the vicinity of the top of each flexible claw 12c, it returns to its original position by the elastic force of each flexible claw 12c itself. When this action is repeated, the loop diameter of the band-like part 11 gradually decreases, and when the desired loop diameter is reached, if the pulling action of the band-like part 11 is stopped, the small-sized part 11a becomes the flexible claw 12c. Since each flexible claw 12c returns to its original position by its own elastic force when it is near the top, the large portion 11b once pulled out from the hollow portion 12a is inhibited by the top 12d of each flexible claw 12c. Thus, the reverse feeding of the belt-like portion 11 is prevented. In this state, that is, in the state of FIG. 5, a locking portion by the large portion 11 b of the belt-like portion 11 and the top portion 12 d of each flexible claw 12 c, so-called lock portion, locking head 12, connecting portion 14, tamper-proof portion 13 and the belt-like portion 11 form one loop.
If an attempt is made to falsify in this state, the top portion 12d of each flexible claw 12c is obstructed by the falsification preventing portion 13, and therefore it is almost impossible to spread the top portion 12d outward.
If this operation is continued forcibly, an external force for expanding the top portion 12d is transmitted to the thin connecting portion 14 and is broken from the connecting portion 14 so that the seal is unraveled. It will be.
Therefore, if this sealing tool is used, an unlimited sense of security can be obtained due to the synergistic effect of the falsification preventing portion 13 and the connecting portion 14.
As described above, various kinds of information on the sealed objects to be sealed are managed by wireless communication using the IC chip 16a and the antenna 16b of the IC tag 16, the reader / writer (not shown), and the antenna.
The managed object to be sealed is eventually opened, but in that case, if the falsification preventing part 13 of the sealing tool in the state of FIG. 5 is picked with a finger and the belt-like part 11 is pulled in the direction opposite to the insertion direction, The thin connecting portion 14 between the locking head 12 and the falsification preventing portion 13 is broken, and the locking head 12 and the falsification preventing portion 13 are separated.
As shown in FIG. 6, the separated locking head 12 remains on the belt-like portion 11 and is not scattered and lost, which is preferable in terms of environment.
In this state, the box X and the lid Y are unsealed if the band X 11 with the locking head 12 is removed from the holes X1 and Y1 of the box X and the lid Y.

Next, the second embodiment will be described. In FIGS. 7 and 8, the belt-like portion 21 is formed in the shape of a filament 21a. As in the first embodiment, the belt-like portion 21 is initially made slightly thick and short, and is elongated and elongated in the longitudinal direction while being molecularly oriented. The advantage of this stretching is that when injection molding is performed using a thermoplastic resin such as polyamide or polypropylene as the raw material, since the strip portion 21 is thick at the beginning of molding, the resin has good fluidity and is easy to mold. In addition, after stretching, the tensile strength in the longitudinal direction of the strip-shaped portion 21 can be increased by molecular orientation, and the flexibility as the strip-shaped portion can be obtained because it is weak in the bending direction. The strip portion 21 is preferably stretched in order to obtain the above advantages, but may be unstretched when strength and flexibility are not important.
On the free end side of the belt-like portion 21 formed in this way, an arrowhead-like coupling portion 21b having blades 21c that can be reduced and enlarged is provided. The coupling portion 21b has a shape that expands from the base toward the free end when enlarged.
On the other hand, the locking portion 22b of the locking head 22 is a fixed tooth 22c having a hole 22a that is smaller than the outer dimension when the coupling portion 21b is enlarged and larger than the outer dimension when the coupling portion 21b is reduced.
Now, a cylindrical tamper-proof portion 23 is provided around the locking head 22 formed as described above. The size of the tamper-proof portion 23 in the axial direction extends in the vertical direction of the hole 22a so that it is difficult to retract the blade 21c of the coupling portion 21b and remove it from the hole 22a of the lock portion 22b of the locking head 22. ing. Further, the falsification preventing portion 23 and the locking head portion 22 are connected by a thin connecting portion 24 that can be broken with a small external force. As in the first embodiment, the connecting portion 24 may be a plurality of connections, or may be a single connection, or the gap between the tamper prevention portion and the locking head is connected with a thin burr-like film. Alternatively, the external force to be broken differs depending on the application, and it may be determined according to the size.
The band-shaped portion 21 described above is extended from the tamper-proof portion 23 formed in this way.
Moreover, from the tampering prevention part 23, the flat display part 25 which is an accessory part is extended in the direction opposite to the extension direction of a strip | belt-shaped part. On the display unit 25, as in the first embodiment, an IC tag is provided or necessary information is displayed.
This sealing tool is integrally injection-molded using a thermoplastic resin such as polyamide or polypropylene as a raw material.

Next, how to use this sealing tool will be described.
When inserting the coupling portion 21b into the hole 22a, the blade 21c of the coupling portion 21b contracts and returns to the original position when the blade 21c passes through the hole 22a, and the fixed teeth 22c prevent the reverse movement. Thus, the coupling portion 21b, the lock portion 22b, the locking head portion 22, the connecting portion 24, the falsification preventing portion 23, and the belt-like portion 21 form one loop.
If an attempt is made to falsify in this state, it is difficult to shrink the blade 21c because there is a distance from the end of the falsification preventing portion 23 to the blade 21c of the coupling portion 21b.
If this operation is continued forcibly, an external force that attempts to shrink the blade 21c is transmitted to the thin connecting portion 24, which is broken from the connecting portion 24 and the seal is released. It will be.
Therefore, if this sealing tool is used, an unlimited sense of security can be obtained due to the synergistic effect of the falsification preventing portion 23 and the connecting portion 24.
In the case of this embodiment, in the locked state, unlike the first embodiment, the surplus portion of the belt-like portion 21 can be prevented from protruding from the falsification preventing portion 23. For example, FIG. As shown in FIG. 9, after the whole is integrally injection-molded, if a part 23 a of the opening portion of the tamper-proofing portion in front of the insertion direction is closed with a resin by using injection molding or the like, the tampering is further performed. The prevention effect can be further enhanced.
When unsealing, if the falsification preventing portion 23 is picked with a finger and the band-like portion 21 is pulled in the direction opposite to the insertion direction, the thin connecting portion 24 between the locking head portion 22 and the falsification preventing portion 23 is broken, The stop head 22 and the falsification preventing part 23 are separated.
The separated locking head 22 remains in the belt-like portion 21 as in the first embodiment, and is not scattered and lost.

Next, the third embodiment will be described. In FIGS. 10 and 11, the second embodiment is different from the second embodiment in that the belt-like portion 31 is folded in the middle, and only the differences will be described. , Others are the same as in the second embodiment, and a description thereof is omitted.

It is formed so as to be disengaged from and disengaged from the serrated teeth 51b in one direction and to prevent the movement of the band-shaped portion 51 in the opposite direction.
Therefore, since it becomes a loop shape simply by inserting the belt-like portion 51 into the engagement head portion 52, the workability is good and the locking portion can be made stronger than the above-described embodiments.
As a result, it is suitable for sealing that requires some strength. In addition, what is necessary is just to strengthen the connection part 54 in the range which does not exceed the intensity | strength of a latching | locking part, when intensity | strength is required.
If the tamper-proof portion 53 is extended to the insertion side of the belt-like portion 51, it becomes difficult to insert a thin plate-like piece B as shown in FIG. Hard to break.

  In addition to the above-described embodiments, the belt-shaped portion may have a U-shaped shape, a V-shaped shape, or an S-shaped shape in the longitudinal direction, and may have a cross-sectional shape other than a circular shape and an elliptical shape and a polygonal shape. Further, in terms of manufacturing, the belt-like portion may be an unstretched one in addition to the stretched one. In short, it may be anything that can be locked in cooperation with the lock portion of the locking head.

  In addition to the above-described embodiments, the tamper-proof portion has a cross-sectional shape as long as it covers the locking head to such an extent that the locking portion between the band-shaped portion and the locking portion can be prevented from being falsified. A hollow circular shape, a hollow elliptical shape, or a hollow polygonal shape, which may be a penetrating cylindrical shape or a cylindrical shape having a bottomed portion.

Further, in addition to the above-described embodiments, the accessory portion may be formed in a Y-shape for attaching other tags and other articles and sandwiched between them, or only the display portion or the entire sealing tool Can be used to stabilize the posture of the device, for example, the display part is sandwiched between objects to be sealed, attached with double-sided tape, etc., or a hole is drilled in the accessory part, and a pin or screw is inserted into this hole. It may be inserted to stabilize the posture, and the accessory portion may be formed in a hook shape or similar shape for use as a hanging device.
The shape of the accessory part is not limited, but other than the above examples, a polygonal flat plate shape, a circular or elliptical flat plate shape, a spherical shape, and similar shapes can be cited. It can be.

  On the other hand, the IC tag may be a magnet that can be turned on or off in addition to those that can be transmitted only, received, or received and transmitted wirelessly.

As described above, according to each embodiment, it is difficult to falsify by the falsification preventing unit, and because the connecting portion is destroyed if it is forcibly tampered with, the synergistic effect of the falsification preventing portion and the connecting portion, An unlimited sense of security can be obtained.
In addition, since the sealing can be easily released with a small external force, the workability at the time of opening is extremely improved.
Furthermore, since the mechanisms of various conventional sealing tools can be utilized, a sealing tool that can make the most of its superiority can be provided.
