JP 2003-330372 A (page 3-4, FIGS. 1 and 3)

  The sealing band of Patent Document 1 cannot be pulled out once the band portion is inserted into the base portion. Therefore, when the sealing band is normally opened, the band portion is forcibly pulled. The thin portion is broken. On the other hand, when the third party opens the sealing band for fraudulent purposes, the band part is forcibly pulled to break the band part from the thin part, so that after the sealing band is opened, There was a problem that it was difficult to deal with because it was not normally recognized whether it was opened or fraudulently opened.

  Therefore, the present invention has been made in view of the above problems, and when the band part is forcibly removed, it is possible to distinguish between normal opening or unlawful opening by changing the way of breaking the base part depending on how to remove the band part. It is an object of the present invention to provide a sealing band that can be easily handled.

In order to achieve such an object, the sealing band according to the present invention has a band portion provided with a meshing portion row on the outer surface and an insertion hole provided at the base end of the band portion through which the band portion is inserted from the distal end. An elastic engagement portion is provided on the inner peripheral surface of the insertion hole, and is engaged with each of the engagement portion rows when the band portion is inserted to prevent reverse removal of the band portion. a synthetic resin sealing band consisting Te, said the side wall elastic engagement portion is provided, and engraved grooves forming the located on either side of the elastic engagement portion and parallel to the insertion direction of the band portion A pair of thin strips having different thicknesses are provided, and a band is formed between the thin strips located at the outlet side of the elastic engagement portion, and the band portion inserted through the insertion hole. the When the normally open disconnecting as peeling said sidewall , The side walls thereof to open to break only one of the thin strip portion, when removed as forcibly pulled out by tamper said band part is inserted into the insertion hole, opening plug from the slit The thin strips on the side are broken so that only a part of the side wall is peeled off.

When the band for sealing according to the present invention is removed by removing the side wall of the band part inserted through the insertion hole by normal opening, only one of the thin strips is broken and the side wall is opened. When removing the band part that was inserted through the cable by forcibly opening it by tampering, both thin strips on the insertion port side were broken from the slit so that only a part of the side wall was peeled off . After the band is opened, it can be distinguished whether it was normally opened or opened illegally, and it is easy to deal with. Further, when the bag is normally opened, the broken one side wall is connected to the base portion on one side and does not scatter to the surroundings, which leads to the beautification of the environment.

  Embodiments of a sealing band according to the present invention will be described below with reference to the drawings. 1 is a perspective view of a sealing band according to the present invention, FIG. 2 (a) is a longitudinal sectional view of a part of the band portion, FIG. 2 (b) is a longitudinal sectional view of a base portion, and FIG. 2 (b) is a cross-sectional view taken along line XX, FIG. 2 (d) is a cross-sectional view taken along line YY of FIG. 2 (b), and FIG. 2 (e) is a cross-sectional view taken along line ZZ of FIG. Each is shown. For example, a sealing band is used to seal a door of a sealed space such as an aircraft cargo container, cargo truck box or warehouse, or when carrying cash or mail in a bag. In this embodiment, a case where the present invention is applied to an aircraft cargo container will be described.

  A sealing band A according to the present invention is integrally formed of a synthetic resin material such as polyethylene, for example, and is provided integrally with a flexible band portion 1 and a base end of the band portion 1. It is comprised from the base | substrate part 2 penetrated from.

  The band portion 1 is formed in a semicircular arc shape so that the tip thereof can be easily inserted into the base portion 2, and the surface which is the outer surface of the band portion 1 is arranged in the longitudinal direction as shown in FIG. A meshing portion row 3 is formed in which a large number of meshing portions 3a that are orthogonal to the longitudinal direction and have a sawtooth cross section are arranged in a row along a certain length. Further, a name entry location 4 for entering the name of the manager who manages the sealing band A is provided on the base end side of the surface of the band portion 1 and a management number printing location 5 is provided on the distal end side. Furthermore, an arrow mark 6 is provided on the tip side.

  On the other hand, the base portion 2 is formed in a horizontally long rectangular parallelepiped shape, and an insertion hole 7 through which the band portion 1 is inserted is provided along the longitudinal direction. One end of the insertion hole 7 is an insertion port 8 of the band portion 1, and the other end is a drawer port 9. The base end of the band portion 1 is connected to the lower side wall 2a on the outlet 9 side. On the insertion port 8 side of the base 2, the leading edge of the upper side wall 2 b is formed shorter than the lower side wall 2 a and both side walls 2 c, 2 c, so that the leading end of the band part 1 can be easily inserted into the insertion hole 7. Yes.

  As shown in FIG. 2 (b), the inner surface of the upper side wall 2b is inclined downward toward the lead-out port 9 and engages with the meshing part row 3 on the band part 1 side to prevent the band part 1 from coming out backward. The meshing part 10 is projected. Further, as shown in FIGS. 2 (c) to 2 (e), the concave groove is located on both sides of the inner surface of the upper side wall 2b, which is a predetermined position of the elastic engagement portion 10, and is parallel to the insertion direction of the band portion 1. 11 is engraved, thereby providing a pair of thin strips 11a and 11b on the upper side wall 2b. Further, a slit 12 that is located closer to the drawing port 9 than the elastic engagement portion 10 and communicates with the insertion hole 7 is formed between the thin-walled portions 11a and 11b. Furthermore, narrow vertical holes 13 and 13 are formed at both side positions of the elastic meshing portion 10 so as to communicate with the insertion hole 7 along the thin strips 11a and 11b.

  On the other hand, the inner surface of the lower side wall 2a is shaped so as to gradually rise as the inner surface advances toward the drawer port 9, and a transverse ridge 14 projects from the position of the drawer port 9. This is because it is necessary to prevent the band portion 1 from coming out backward while the elastic meshing portion 10 is engaged with the meshing portion row 3, so that the vertical interval of the insertion portion 7 is narrowed and the engagement is performed firmly. It is to make it.

  The thin strips 11a and 11b are easily cut from the portions, but the other thin strip 11b is formed thinner than the one thin strip 11a. Therefore, if an external force is applied to the upper side wall 2b from a direction perpendicular to the surface, the thinner thin-walled portion 11b is always broken, and the one thin-walled portion 11a is not broken. . This is for the purpose of beautifying the environment by preventing the fragments (upper side wall 2b), which are no longer needed by breaking, from scattering around. An arrow mark 15 is also provided on the upper surface of the base portion 2 to show the insertion direction of the band portion 1 to the base portion 2 in an easy-to-understand manner.

  The sealing band A according to the present invention has the above-described configuration, and a method for using the same will now be described. FIG. 3 shows an example of an aircraft cargo container to which the sealing band according to the present invention is applied. The cargo container 20 is made of metal and is formed in a substantially rectangular shape, and a cargo entrance 21 is opened on one side surface thereof. An upper door 22a and a lower door 22b are attached to the entrance / exit 21 so as to be positioned vertically, and the upper door 22a is pivotally attached at the upper edge and rotates in the front-rear direction with the pivoted portion as a fulcrum. The lower door 22b is pivotally attached at the lower edge and is also rotated in the front-rear direction using the pivoted portion as a fulcrum.

  When the lower door 22b is closed, the upper door 22a is held at its lower edge by being pressed by the upper edge of the lower door 22b. Further, the lower door 22b is provided with locking mechanisms 23, 23 on both upper sides thereof. Each lock mechanism 23 is provided in a recess 24 formed on the front surface of the lower door 22b as shown in FIG. 4, and one end side is inserted into a shaft hole 25 provided on the inner surface of the recess 24. 26 and a stop rod 27 that protrudes from the bottom surface and restricts the operation of the lock rod 26.

  The lock rod 26 is provided in parallel with the shaft center of the shaft attachment portion of the lower door 22b. The lock rod 26 freely slides in the left-right direction along the central axis, and also rotates back and forth around the central axis. Further, a U-shaped frame 29 for inserting the sealing band A is fixed to the inner side surface of the recess 24 provided with the shaft hole 25 so as to be close to the bent flange portion 28.

  Here, since the operation of both lock mechanisms 23 and 23 is the same, one lock mechanism 23 will be described as shown in FIG. First, while the lower door 22b is closed, the lock rod 26 is rotated while sliding to the left side, one end side thereof is inserted into the shaft hole 25, and the bent rod portion 28 is disposed at the left side position of the stop rod 27. . As a result, the bent hook portion 28 hits the stopper rod 27 to prevent the lock rod 26 from returning backward, and the lower door 22b is locked. Therefore, the lock rod 26 is rotated while the lock rod 26 is slid in the opposite direction, and the bent rod portion 28 cannot be unlocked unless it is arranged at the right side of the stop rod 27.

  Therefore, in the present invention, as shown in FIG. 4, with the lower door 22b locked, the band portion 1 is inserted into the U-shaped frame 29 and turned to the back side of the bent collar portion 28, and the tip end portion is left as it is. It is inserted into the base 2 and fastened in the direction of the arrow in the figure. Thereby, the lock mechanism 23 is sealed.

  In the present invention, after the cargo is loaded into the cargo container 20, the upper door 22a and the lower door 22b are closed, the lock mechanisms 23 and 23 of the lower door 22b are locked, and further, the sealing band A is used for sealing. do. Then, when the cargo is normally loaded and unloaded from the cargo container 20, as shown in FIG. 5, the band portion tip side of the sealing band A is grasped with a finger, and the upper side wall 2b is pulled off as it is. As a result, the upper side wall 2b of the base portion 2 is pushed in the direction orthogonal to the wall surface from the outlet 9 side, and one thin strip portion 11a is not broken and thinner as shown in FIG. Only the other thin strip 11b is broken.

  In this way, the band portion 1 is detached from the base portion 2, and each lock mechanism 23 is opened. Finally, both lock rods 26 and 26 are slid to open the lower door 22b, and then the upper door 22a is opened to take out the cargo. At this time, one side of the broken upper side wall 2b is connected to the base portion 2 via one thin strip portion 11a, so that it does not scatter unnecessarily and stain the surroundings.

  On the other hand, when the cargo is loaded and sealed, when someone opens the upper and lower doors 22a and 22b and attempts to steal the cargo without permission, the lock band 23 and 23 are unlocked. When the band portion 1 is forcibly pulled out from the base portion 2 in an attempt to open, the meshing portion 3a engaged with the elastic meshing portion 10 is connected to the elastic meshing portion 10 in the insertion direction of the band portion 1 as shown in FIG. Presses in the opposite direction.

  As a result, an external force along the wall surface is applied to the upper side wall 2b, and finally the thin strips 11a, 11b on both sides are simultaneously sheared and broken, and the corresponding upper side wall as shown in FIG. Only a part 2b-1 of 2b is peeled off. At this time, since the vertical holes 13 and 13 are formed along the thin strips 11a and 11b, the part 2b-1 of the upper side wall 2b is easily broken. Further, since the slit 12 is formed on the side of the outlet 9 of the elastic meshing portion 10, the external force is not applied to the part 2b-2 of the upper side wall 2b on the side of the outlet 9 from that. A part 2b-2 of the side wall 2b remains as it is.

  Thus, the part 2b-1 of the upper side wall 2b is broken and cannot be repaired. Therefore, even if both locking mechanisms 23 and 23 are locked after theft, a part 2b-1 of the upper side wall 2b of the base portion 2 remains broken, and it is easy to immediately understand and deal with fraud. In addition, when the sealing band A is broken by normal opening and when the sealing band A is broken by fraud, the broken state is different, so that it is possible to distinguish between the normal case and the fraud case. , Easy to deal with.

  As described above, in the sealing band A according to the present invention, when the band part 1 is forcibly removed in a state where the band part 1 is inserted into the insertion hole 7, one of the thin strips is removed depending on how the band part 1 is removed. Only the portion 11b is broken and one side wall 2b of the base portion 2 is opened, or both thin strips 11a and 11b on the insertion port 8 side are broken from the slit 12 and only a part 2b-1 of the one side wall 2b is broken. Since it is peeled off, after the sealing band A is opened, it is easy to deal with it by distinguishing whether it is normally opened or opened illegally. Further, since the base portion 2 is configured to be easily broken, a person who cheats is hesitant to act as a kind of act, thereby also having a deterrent effect.
