Description

  The present invention relates to a sealing tool for sealing a sealed object.

  Conventionally, a sealing tool for sealing a sealed object has been used. For example, in large-scale events such as sports competitions and concerts, in order to prevent dangers such as terrorism, visitors are inspected for baggage using an X-ray imaging device, etc., and equipment inspection using a metal detector, etc. It is hoped that. However, conducting both baggage inspection and equipment inspection at the entrance of the venue for a large number of visitors in a large-scale event causes congestion and confusion. Therefore, there are cases where the baggage inspection is performed around the nearest station of the venue, and the equipment is inspected at the entrance of the venue to disperse the congestion. In this case, since the place where the baggage inspection is carried out and the place where the attachment inspection is carried out are separated, in order to seal the checked baggage so that no dangerous goods can be put into the checked baggage in the meantime It is necessary to use a sealing tool.

  Further, this sealing tool is required to have flexibility to cope with sealing objects of various shapes and to be inexpensive to be applied to a large number of visitors. Therefore, it is desirable to use a sealing tool made of a sheet such as a bag.

  On the other hand, an adhesive tape for detecting that the seal has been broken is known. For example, Patent Document 1 is a pressure-sensitive adhesive tape in which conductive wires are stretched, and has a structure in which the conductive wires are cut when the pressure-sensitive adhesive tape is peeled off from a trunk or the like containing a sealed object. The adhesive tape which detects that the said adhesive tape was peeled off by having cut | disconnected is described.

JP 2000-29390 A

  However, when the object to be sealed is wrapped in a sheet and the sheet is sealed with a conventional adhesive tape, a malicious person cuts the sheet, for example, opens the seal, and then performs a work such as closing the cut In addition, the inspector could not recognize that the seal was released.

  Therefore, it is conceivable to detect that the sheet has been cut by extending a conductive wire around the sheet. However, it is difficult to stretch the conductive wire over the entire surface of the sheet because of the manufacturing convenience of the sheet, and, for example, a margin where the conductive line is not wired at the edge of the sheet, that is, a non-wiring region is formed. Therefore, there arises a problem that when the non-wiring area of the sheet that encloses the sealing object is cut or the sealing is released, it cannot be detected.

  The objective of this invention is providing the sealing tool which can detect more reliably that sealing was cancelled | released, when a sealing target object is sealed using the sheet | seat which has a non-wiring area | region.

  The present invention is a sealing tool for sealing an object to be sealed, in which a first conductive wire is wired, a first contact provided at one end of the first conductive wire, and the other end of the first conductive wire. A sheet having a wiring area including a second contact provided on the sheet, a non-wiring area where the first conductive line is not wired, and an adhesive tape wired with a second conductive line, An adhesive tape having a third contact provided at one end of the conductive wire and a fourth contact provided at the other end of the second conductive wire, the adhesive tape covering the non-wiring region. In addition, the first contact and the third contact are electrically connected, and the second contact and the fourth contact are electrically connected, so that the first conductive line and the second contact are connected. Attached to the sheet so that a closed circuit is formed by a conductive wire, and detects a disconnection of the closed circuit. It characterized that it is possible to detect that the seal has been solved by.

  Preferably, the second conductive line is a stacked layer in which a first layer wired along a first direction and a second layer wired along a second direction intersecting the first direction are stacked. It has a structure.

  Preferably, when the sheet is formed in a bag shape, the first contact is located on one side surface of the opening, and the second contact is located on the other side surface of the opening.

  Preferably, an adhesive is applied non-uniformly on the adhesive surface of the pressure-sensitive adhesive tape.

  Preferably, the first contact, the second contact, the third contact, and the fourth contact have a shape having a longitudinal direction, and the adhesive tape is attached to the sheet, The longitudinal direction of the first contact is different from the longitudinal direction of the third contact, and the longitudinal direction of the second contact is different from the longitudinal direction of the fourth contact.

  Hereinafter, embodiments of the present invention will be described.

  FIG. 1 shows a plan view of a sheet 10 included in the sealing tool according to the present embodiment. The sheet 10 has a strength that can seal a sealed object, and is soft enough to be folded so as to wrap sealed objects of various shapes. In the present embodiment, the sheet 10 has a rectangular shape, but the shape of the sheet 10 may be other shapes as long as the object to be sealed can be suitably sealed. In FIG. 1, the direction in which the long side of the sheet 10 extends is the X-axis direction, and the direction in which the short side of the sheet 10 extends is the Y-axis direction.

  The sheet 10 has a laminated structure, and a surface layer that protects the surface of the sheet 10, a first layer and a second layer having wiring, a bagging layer that forms a base material, and a conductive layer, which will be described later, penetrate each other. It includes an insulating layer that insulates it from contact other than vias and contacts. In FIG. 1A, the surface layer and the first layer are shown, and in FIG. 1B, the second layer is shown.

  In the sheet 10, the first layer wiring 12 and the second layer wiring 14 are stretched, and a wiring region 16 including a first contact 24a and a second contact 24b, which will be described later, and the first layer wiring 12 and the second layer wiring 14 are arranged. And a non-wiring area 18 that is not wired. In the present embodiment, the position along the edge of the sheet 10 is a non-wiring area 18, and the inner area of the non-wiring area 18 is a wiring area 16. The non-wiring area 18 is generated due to the manufacturing convenience of the sheet 10.

  The first layer wiring 12 is formed of a metal such as copper, for example, and is stretched around the first layer of the sheet 10. The first layer is a layer located below the surface layer. The first layer wiring 12 is wired along the Y-axis direction. That is, the first layer wiring 12 has a plurality of linear regions extending in the Y-axis direction and arranged in the X-axis direction. The ends of the adjacent linear regions are connected to each other, whereby the first layer wiring 12 is a linear conductive line.

  The second layer wiring 14 is formed of a metal such as copper, for example, and is stretched around the second layer of the sheet 10. In the present embodiment, the second layer is located below the first layer. The second layer wiring 14 is wired along the X-axis direction. That is, the second layer wiring 14 has a plurality of linear regions extending in the X-axis direction and arranged in the Y-axis direction. The ends of the adjacent linear regions are connected to each other, whereby the second layer wiring 14 is also a linear conductive line.

  The first layer wiring 12 and the second layer wiring 14 are electrically connected (hereinafter simply referred to as “connection”) by through vias 20a and 20b. Thereby, the first conductive line 22 composed of the first layer wiring 12 and the second layer wiring 14 is formed. As described above, since the first layer wiring 12 and the second layer wiring 14 are linear conductive lines, the first conductive line 22 is a single conductive path having no branch point. In addition, since the first layer wiring 12 and the second layer wiring 14 are wired in a direction crossing each other, the first conductive lines 22 are wired in a lattice shape when viewed in a plan view. Thereby, even if the sheet 10 is cut in any direction (cut, torn, or punched), the first conductive line 22 is cut.

  A first contact 24 a is provided at one end of the first conductive wire 22. The first contact 24 a is connected to the first conductive wire 22 and is exposed to the surface layer of the sheet 10. A second contact 24 b is provided at the other end of the first conductive line 22. The second contact 24 b is also connected to the first conductive line 22 and is exposed to the surface layer of the sheet 10. The first contact 24a and the second contact 24b have a shape having a longitudinal direction. In the present embodiment, the first contact 24a and the second contact 24b are rectangular. The first contact 24a and the second contact 24b are formed of a conductive material, and may be, for example, a copper foil surface.

  A detection member first contact 26 a and a detection member second contact 26 b are provided in the middle of the first conductive wire 22. The detection member first contact 26a and the detection member second contact 26b are also exposed to the surface layer of the sheet 10, and are formed of a conductive material (for example, a copper foil surface). These contacts are connected to two contacts of a disconnection detecting member 60 described later. The disconnection detecting member 60 detects the disconnection of the first conductive wire 22 or the second conductive wire 48 included in the adhesive tape 40 described later, and thereby the sealing by the sealing tool composed of the sheet 10 and the adhesive tape 40 is released. This is to detect this.

  The top view of the adhesive tape 40 contained in the sealing tool which concerns on this embodiment is shown by FIG. The adhesive tape 40 is affixed to the sheet 10 so as to cover the non-wiring region 18 of the sheet 10 in order to seal the object to be sealed. In the present embodiment, the adhesive tape 40 has a rectangular shape, but may have other shapes. In FIG. 2, the direction in which the long side of the adhesive tape 40 extends is the X-axis direction, and the direction in which the short side of the adhesive tape 40 extends is the Y-axis direction.

  Similar to the sheet 10, the adhesive tape 40 also has a laminated structure, a surface layer that protects the surface of the adhesive tape 40, first and second layers having wiring, a back surface layer exposed on the back surface of the adhesive tape 40, and A plurality of insulating layers for insulating each of the above layers is included. 2A shows the first layer, and FIG. 2B shows the second layer and the back layer.

  A first layer wiring 42 is stretched around the first layer located below the surface layer. The first layer wiring 42 is formed of a metal such as copper, for example, like the sheet 10. The first layer wiring 42 is wired along the X-axis direction as the first direction. That is, the first layer wiring 42 has a plurality of linear regions extending in the X-axis direction and arranged in the Y-axis direction. The ends of the adjacent linear regions are connected to each other, whereby the first layer wiring 42 is a linear conductive line.

  A second layer wiring 44 is stretched around the second layer located below the first layer. Similar to the sheet 10, the second layer wiring 44 is formed of a metal such as copper. The second layer wiring 44 is wired along the Y-axis direction as the second direction intersecting the first direction. That is, the second layer wiring 44 has a plurality of linear regions extending in the Y-axis direction and arranged in the X-axis direction. The ends of adjacent linear regions are connected to each other, whereby the second layer wiring 44 is also a linear conductive line.

  The first layer wiring 42 and the second layer wiring 44 are connected by through vias 46 a and 46 b, thereby forming a second conductive line 48 composed of the first layer wiring 42 and the second layer wiring 44. As described above, since the first layer wiring 42 and the second layer wiring 44 are linear conductive lines, like the first conductive line 22, the second conductive line 48 is also a single conductive path without a branch point. . In addition, since the first layer wiring 42 and the second layer wiring 44 are wired in a direction crossing each other, the second conductive lines 48 are wired in a lattice shape when seen in a plan view. Thereby, even if the adhesive tape 40 is cut in any direction, the second conductive wire 48 is cut.

  A third contact 50 a is provided at one end of the second conductive line 48. The third contact 50 a is connected to the second conductive line 48 and is exposed on the back layer of the adhesive tape 40. A fourth contact 50 b is provided at the other end of the second conductive wire 48. The fourth contact 50 b is also connected to the second conductive line 48 and is exposed on the back layer of the adhesive tape 40. The third contact 50a and the fourth contact 50b have a shape having a longitudinal direction. In the present embodiment, the third contact 50a and the fourth contact 50b are rectangular. The third contact 50a and the fourth contact 50b are formed of a conductive material, and may be, for example, a copper foil surface.

  The third contact 50 a is connected to the first contact 24 a of the sheet 10, and the fourth contact 50 b is connected to the second contact 24 b of the sheet 10. Thereby, a closed circuit is formed by the first conductive line 22 and the second conductive line 48.

  The back surface of the adhesive tape 40 is an adhesive surface 52 to which an adhesive is applied. The adhesive tape 40 is attached to the sheet 10 by the adhesive surface 52. The adhesive tape 40 may have a release paper that covers the adhesive surface 52 in order to prevent the adhesive surface 52 from being soiled.

  On the bonding surface 52, the adhesive is applied non-uniformly in the surface direction. For example, the application thickness of the adhesive is changed at each position on the bonding surface 52. Thereby, when the adhesive tape 40 is applied across the non-wiring area 18 and the wiring area 16 of the sheet 10, it is possible to more reliably detect that the adhesive tape 40 has been peeled off from the sheet 10. When the adhesive tape 40 is peeled from the sheet 10 and the stress applied to the sheet 10 (first conductive wire 22) is small, the first conductive wire 22 does not detach from the sheet 10 or the first conductive wire 22 Even if the sheet 10 floats slightly from the sheet 10, the adhesive tape 40 may be peeled off in a state where the continuity is maintained (that is, a state where the sheet 10 is not cut). When the adhesive tape 40 is peeled off from the sheet 10 by applying the adhesive nonuniformly on the adhesive surface 52, compared to the case where the adhesive is applied uniformly, the sheet 10 (first conductive wire 22). The stress applied to can be increased. Thereby, when the adhesive tape 40 is peeled off, the first conductive wire 22 becomes easier to cut. That is, it becomes possible to more reliably detect that the adhesive tape 40 has been peeled off.

  FIG. 3 is a perspective view of a disconnection detection member 60 that is attached to the sheet 10 and detects a disconnection of the first conductive line 22 and the second conductive line 48. FIG. 3A shows an upright state, and FIG. 3B shows an inverted state.

  The back surface of the disconnection detection member 60 is an adhesive surface 62, and the disconnection detection member 60 is attached to the sheet by the adhesive surface 62. The detection member side first contact 64 a and the detection member side second contact 64 b are exposed on the back surface of the disconnection detection member 60. The detection member side first contact 64 a is connected to the detection member first contact 26 a provided on the sheet 10, and the detection member side second contact 64 b is connected to the detection member second contact 26 b provided on the sheet 10. It is what is done. As long as the first contact for detection member 26a and the first contact for detection member side 64a are connected and the second contact for detection member 26b and the second contact for detection member 64b are connected, the disconnection detection member 60 is connected. The attachment method to the sheet 10 may be another method.

  In the present embodiment, the disconnection detection member 60 incorporates a battery such as a button battery, an electrical resistance, a current sensor, and a buzzer 66. The battery and the electrical resistance are connected in series between the detection member side first contact 64a and the detection member side second contact 64b. Thereby, when the disconnection detection member 60 is attached to the sheet 10, a current flows in the closed circuit formed by the first conductive line 22 and the second conductive line 48.

  When the sheet 10 is cut (that is, the seal is released) and the first conductive wire 22 or the second conductive wire 48 is disconnected, no current flows in the closed circuit. When the current sensor detects it, an alarm is output at the buzzer 66. Thus, the disconnection detection member 60 detects that the closed circuit disconnection formed by the first conductive line 22 and the second conductive line 48, that is, the seal has been released, and outputs an alarm.

  Note that the method for detecting the disconnection of the closed circuit including the first conductive line 22 and the second conductive line 48 is not limited to the above method. The alarm output method may be a method other than the buzzer 66. For example, the disconnection detection member 60 may include a communication unit, and when current stops flowing in a closed circuit, a notification may be transmitted from the communication unit to a crime prevention center or the like. Further, the disconnection detecting member 60 includes a built-in or external memory for storing the disconnection of the closed circuit, and the closed circuit that has been disconnected after the seal is illegally broken is further illegally electrically connected. However, it may be possible to detect that the seal is once broken. In the present embodiment, the disconnection detection member 60 is always attached to the sheet 10, but the inspector may carry the disconnection detection member 60 and attach it to the sheet 10 only at the time of inspection.

  Hereinafter, a specific method for attaching the adhesive tape 40 to the sheet 10 will be described.

  FIG. 4 shows a bag-like sheet 10. As shown in FIG. 4, the sheet 10 is folded into a bag shape. A sealed object is inserted into the bag-like sheet 10. When the sheet 10 is formed in a bag shape, it is preferable to prevent the non-wiring region 18 provided at the edge of the sheet 10 from being exposed to the outside as much as possible. For example, the bottom portion 70 of the bag-like sheet 10 is preferably formed by being plunged a plurality of times. In addition, in order to form a closed circuit by the 1st conductive wire 22 of the sheet | seat 10, and the 2nd conductive wire 48 of the adhesive tape 40, when the sheet | seat 10 becomes bag shape, the 1st contact 24a and the 2nd contact 24b Is exposed to the outside. Further, when the sheet 10 is formed in a bag shape for attaching the disconnection detecting member 60, the detection member first contact 26a and the detection member second contact 26b are also exposed to the outside.

  Since it is necessary to put a sealed object, the bag-like sheet 10 has an opening 72. Since the opening 72 is naturally provided at the edge of the sheet 10, the non-wiring region 18 a inevitably exists in the vicinity of the opening 72 as shown in FIG. 4. In the method of closing the opening 72 by simply bonding the opposing non-wiring area 18a or the like, when the non-wiring area 18a is cut or the like and the seal is released, the disconnection detecting member 60 can detect it. Can not. Although the non-wiring region 18b extending in the longitudinal direction of the bag-like sheet 10 is also exposed to the outside, the wiring region 16 of the sheet 10 is overlapped inside the non-wiring region 18b, and thus the non-wiring region 18b. Even if the sheet 10 is cut to the inside at the position, it can be detected by the disconnection detecting member 60.

  In the present embodiment, the adhesive tape 40 is affixed to the sheet 10 so as to cover the non-wiring region 18a so that the disconnection detection member 60 can detect even when the vicinity of the opening 72 is cut. Here, the non-wiring area 18 that needs to be covered with the adhesive tape 40 is an area that is exposed to the outside when the sheet 10 is formed in a bag shape, and the wiring area 16 is not overlapped inside the area. It is.

  The first contact 24a of the sheet 10 and the third contact 50a of the adhesive tape 40 are in contact (that is, connected), and the second contact 24b of the sheet 10 and the fourth contact 50b of the adhesive tape 40 are in contact. The adhesive tape 40 is attached to the sheet 10 so as to be connected (that is, connected). As a result, a closed circuit is formed by the first conductive line 22 and the second conductive line 48 as described above.

  When the sheet 10 is formed in a bag shape, the first contact 24a is located on one side surface of the opening 72 (the surface on the labor side in the example of FIG. 4), and the other side surface of the opening 72 (example of FIG. 4). In this case, it is preferable that the second contact 24b be positioned on the back surface. When the adhesive tape 40 is attached to the sheet 10, the contacts need to be connected, so that the alignment between the adhesive tape 40 and the sheet 10 is necessary. The first contact 24 a and the second contact 24 b are the above-described contacts. If the positional relationship is, the alignment can be performed more easily.

  Specifically, when the first contact 24a and the second contact 24b are in the above positional relationship, the first contact 24a and the third contact 50a are aligned, and the second contact 24b and the fourth contact 50b are positioned. Matching can be done in stages. For example, as shown in FIG. 5, first, the first contact 24a and the third contact 50a are aligned on one side surface, and then the adhesive tape 40 is folded to the other side so that the second contact 24b and the second contact Positioning with the four contacts 50b can be performed. Thereby, alignment with the adhesive tape 40 and the sheet | seat 10 becomes easier.

  FIG. 5 also shows a state in which the non-wiring region 18 a is covered by sticking the adhesive tape 40 to the edge of the sheet 10.

  As described above, the first contact 24a, the second contact 24b, the third contact 50a, and the fourth contact 50b have a shape having a longitudinal direction (in this embodiment, a rectangle). As shown in FIGS. 5 and 6, the longitudinal direction of the first contact 24 a and the longitudinal direction of the third contact 50 a are different when the adhesive tape 40 is attached to the sheet 10.

  FIG. 6 shows the positional relationship between the first contact 24a and the third contact 50a in the connected state. Electrical conduction between the two is taken at the blackened portion, which is the overlapping portion of the two. Even if the position of the adhesive tape 40 (third contact 50a) is slightly shifted from the sheet 10 (first contact 24a) due to the different longitudinal directions of the first contact 24a and the third contact 50a, they are connected. It becomes possible.

  For example, if the lengths of the short sides of the first contact 24a and the third contact 50a are L, when the longitudinal direction of both is aligned in the Y-axis direction, the third contact 50a is connected to the X-axis with respect to the first contact 24a. If the direction is shifted by a distance L or more, the two are not connected. On the other hand, if the longitudinal direction of the first contact 24a is the Y-axis direction and the longitudinal direction of the third contact 50a is the X-axis direction, that is, if the longitudinal direction of both the contacts intersects, the first contact 24a On the other hand, even if the third contact 50a deviates by a distance L or more in the X-axis direction, both can be connected to some extent.

  From the same viewpoint, the longitudinal direction of the second contact 24b and the longitudinal direction of the fourth contact 50b are different in a state where the adhesive tape 40 is adhered to the sheet 10.

  FIG. 7 shows a state where the adhesive tape 40 is attached to the sheet 10 and the disconnection detection member 60 is attached. As shown in FIG. 7, by sticking the adhesive tape 40 to the sheet 10, the non-wiring region 18 a near the opening 72 is covered with the adhesive tape 40, and the first conductive line 22 and the second conductive line 48 are As a result, a closed circuit is formed. As a result, the entire periphery of the object to be sealed is surrounded by the closed circuit, so that it is possible to more reliably detect that the seal has been released.

  Further, when carrying the above-mentioned sealing tool that seals the object to be sealed, if the first conductive wire 22 or the second conductive wire 48 is cut by pulling the sheet 10 or the adhesive tape 40, the sealing is released. Will be mistakenly detected. In order to prevent this, a handle for carrying the sealing tool may be prepared. The handle is preferably one that supports the sealing tool that seals the sealing object from the bottom so that the sheet 10 or the adhesive tape 40 is not stressed.

  As mentioned above, although embodiment which concerns on this invention was described, this invention is not limited to the said embodiment, A various change is possible unless it deviates from the meaning of this invention.

  The case where the sheet 10 and the adhesive tape 40 are electrically connected by the connection of the first contact 24a and the third contact 50a and the connection of the second contact 24b and the fourth contact 50b, that is, two points arranged near the center of the adhesive tape 40 will be described. However, in order to improve the monitoring property of the adhesive tape 40, the number of contacts may be further increased. For example, contacts can be arranged at the four corners of the adhesive tape 40 to have four points, and contacts can be arranged at the center and four corners to have six points. At this time, the sheet 10 has one conductive line in the case of four points and two conductive lines in the case of six points in the region between the first contact 24a and the second contact 24b at two points. It is only necessary to form one closed circuit by connecting the contacts at both ends to the contacts of the adhesive tape 40. Each of the sheet 10 and the adhesive tape 40 is composed of a plurality of conductive lines, but the first layer wiring and the second layer wiring of each laminated structure must be in a relationship that always intersects with other conductive lines. That's fine.
