Description

  The present invention is a fraud that makes the machine-readable code unrecognizable when the first base material part on which the machine-readable code is displayed is peeled off from the second base material part after being attached to the second base material part. Regarding prevention structure.

  2. Description of the Related Art Conventionally, in a label attached to an adherend, various contrivances have been made for detecting that the label is illegally peeled after being attached.

  For example, when it is peeled off after being attached to the adherend, the label is attached again to the adherend by leaving a part of the colored adhesive layer or print layer on the adherend side. However, a structure that leaves a trace of peeling is considered. In addition, when it is peeled off after being attached to the adherend, a structure that leaves a trace of peeling is considered even when the label is attached again to the adherend by destroying part of the printed layer. (For example, refer to Patent Document 1).

Japanese Patent No. 3690673

  In the label as described above, a barcode or a two-dimensional code is displayed and used to manage a product or the like with the label attached by reading the displayed barcode or the two-dimensional code. is there. In that case, even if it is affixed to the product again after being illegally peeled off from the product etc. as described above, although the trace of peeling can be confirmed visually, the displayed barcode or two-dimensional code There is a problem that it can be read.

  The present invention has been made in view of the problems of the conventional techniques as described above, and the first base portion on which the machine reading code is displayed is attached to the second base portion. (2) An object of the present invention is to provide a tamper-proof structure that can make a machine-readable code unrecognizable when peeled off from a base material part, a label used for the structure, and a tamper-proof method.

In order to achieve the above object, the present invention provides:
A tamper-proof structure that makes the machine-readable code unrecognizable when the first base material portion on which the machine-readable code is displayed is peeled off from the second base material portion after being attached to the second base material portion Because
The machine reading code is made of an infrared absorbing material,
The first base portion is
A base substrate on which the machine reading code is displayed;
A metal layer that is laminated over the entire surface of one side of the base substrate, and at least part of which is destroyed when the first substrate portion is peeled off after being attached to the second substrate portion;
An adhesive layer laminated on the side opposite to the base substrate of the metal layer;
The second base material portion has an absorption layer made of the infrared absorbing material on the entire surface of the region facing the display region of the machine reading code when the first base material portion is attached.

  In the present invention configured as described above, in order to read the machine reading code displayed on the base substrate in the state where the first base material portion and the second base material portion are properly attached, When infrared rays are irradiated from the base material side, the irradiated infrared rays are absorbed by the machine reading code made of an infrared absorbing material in the machine reading code, and are reflected by the metal layer in the other areas. By detecting the reflected wave, the machine reading code is correctly recognized. On the other hand, if it peels after the 1st base material part and the 2nd base material part are stuck, at least one part of a metal layer will destroy. Thereafter, when infrared light is irradiated from the first base material portion side in order to read the machine reading code in a state where the first base material portion and the second base material portion are improperly attached, at least one of the metal layers. Since the part is destroyed, infrared rays are transmitted without being reflected in the destroyed part. However, the mechanical reading code of the second base part attached to the first base part Since an absorption layer made of an infrared absorbing material is provided on the entire surface facing the display area, the infrared rays transmitted through the broken portion of the metal layer are also absorbed by this absorption layer. For this reason, even when the reflected infrared reflected wave is detected, the reflected wave is different from the reflected wave by the machine reading code, and the machine reading code cannot be recognized.

  As such a fraud prevention structure, the first base part and the second base part are integrated, or the first base part and the second base part are configured as separate bodies. Can be considered.

  In addition, as for the first base material part and the second base material part integrated, the base base material has a continuous belt-like shape across the first base material part and the second base material part, and absorbs the base material part. The layer is laminated on the same surface as the machine reading code of the base substrate, and the base substrate is annular so that the machine reading code is displayed and the absorption layer is laminated on the outside. The first base material part and the second base material part may be used by being attached by the adhesive layer in a state where the machine reading code faces the absorption layer.

  According to the present invention, when the first base material portion and the second base material portion are peeled off after being pasted, at least a part of the metal layer is destroyed. When infrared light is irradiated from the first base material part side in order to read the machine reading code in a state where the base material part is improperly attached, the irradiated infrared light is not only the machine reading code but also the first group. Even if the reflected wave of the infrared ray absorbed and absorbed by the absorption layer of the second base material part attached to the material part is detected, the reflected wave is different from the reflected wave by the machine reading code. Thus, the machine reading code can be made unrecognizable.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 is a diagram showing an example of a security band having the first embodiment of the fraud prevention structure of the present invention, where (a) is a front view and (b) is an AA ′ shown in (a). Sectional drawing (c) is a figure which shows the structure of the surface of the transparent film 10. FIG.

  As shown in FIG. 1, this embodiment is a belt-shaped security band 1 in which a first base material portion 2 and a second base material portion 3 are continuously integrated.

  The security band 1 has a two-dimensional code 12 as a machine reading code displayed in a region to be the first base material portion 2 on one surface of the band-shaped transparent film 10 to be a base base material, and a second base A solid print layer 13 serving as an absorption layer is laminated in a region serving as the material part 3. The two-dimensional code 12 and the solid print layer 13 are displayed and laminated by printing using an ink containing carbon which is an infrared absorbing material. On the surface on which the two-dimensional code 12 of the transparent film 10 is displayed and the solid printing layer 13 is laminated, a printing layer 21 made of white ink that does not contain an infrared absorbing material is laminated. On the layer 21, the printing layer 22 is laminated | stacked by displaying information using the ink which does not contain an infrared rays absorption material. The two-dimensional code 12 is concealed by the print layers 21 and 22, but the code recognition unit 2 a facing the two-dimensional code 12 can be recognized by the information displayed by the print layer 22.

  A release layer 40 is partially laminated on the surface of the transparent film 10 opposite to the two-dimensional code 12 and the solid print layer 13 by pattern application of a release agent. Furthermore, aluminum is deposited on the entire surface of the transparent film 10 opposite to the two-dimensional code 12 and the solid print layer 13 by covering the release layer 40, thereby laminating an aluminum deposition layer 30 to be a metal layer. Has been.

  The adhesive layer 50 is laminated on the entire surface of the aluminum vapor-deposited layer 30 opposite to the laminated surface with the transparent film 10 by applying an adhesive or an adhesive, and the adhesive layer 50 is interposed therebetween. The release paper 60 is attached so as to be peelable.

  In the release paper 60, a slit 61 penetrating the front and back is formed at a boundary portion between the first base material portion 2 and the second base material portion 3.

  Below, the usage method of the security band 1 comprised as mentioned above is demonstrated.

  First, the usage state of the security band 1 shown in FIG. 1 will be described.

  FIG. 2 is a diagram illustrating a usage state of the security band 1 illustrated in FIG. 1. 3 is a cross-sectional view of the vicinity of the two-dimensional code 12 in the use state shown in FIG. 2 of the security band 1 shown in FIG.

  When using the security band 1 shown in FIG. 1, first, a region on the first base material part 2 side is peeled through the slit 61 in the release paper 60, and the adhesive layer 50 is peeled off in the first base material part 2. To express.

  Then, as shown in FIG. 2, the surface on which the printed layer 22 of the second base material portion 3 is laminated by the adhesive layer 50 that is formed in an annular shape so that the release paper 60 is inside and wound around the arm 4. The 1st base material part 2 is stuck on top. In addition, it is also conceivable that another base material such as a film is bonded to the second base material portion 3 side of the release paper 60 via the slit 61. In that case, by using a material made of a material that is safe to touch the skin as a base material to be bonded, when wound around the arm 4 as shown in FIG. Can be avoided.

  In the state where the security band 1 is wound around the arm 4 and the first base material part 2 is adhered to the second base material part 3, the first base is formed on the second base material part 3 as shown in FIG. It will be in the state by which the material part 2 was laminated | stacked. That is, in the 2nd base material part 3, when the 1st base material part 2 is stuck, the solid printing layer 13 is laminated | stacked on the whole surface of the area | region facing the display area of the two-dimensional code 12. Become. In this state, by placing the barcode reader on the code recognition unit 2a, the two-dimensional code 12 is read and recognized by infrared rays serving as reading light emitted from the barcode reader.

  Next, after the 1st base material part 2 is affixed on the 2nd base material part 3 as mentioned above, these are peeled illegally and the effect | action at the time of being affixed again is demonstrated.

  FIG. 4 illustrates the action when the first base material portion 2 and the second base material portion 3 of the security band 1 shown in FIG. It is a figure for performing, and the cross section of the two-dimensional code 12 vicinity is shown.

  When the first base material portion 2 and the second base material portion 3 of the security band 1 shown in FIG. 1 are attached and then peeled, as shown in FIG. In the laminated region, the peeling layer 40 peels from the transparent film 10 in the first base material portion 2, and in the region where the peeling layer 40 is not laminated, the adhesive layer 50 of the first base material portion 2. Is peeled off from the printing layer 22 of the second base material portion 3.

  And when the 1st base material part 2 and the 2nd base material part 3 peel completely, as shown in FIG.4 (b), the aluminum vapor deposition layer 30 and the adhesion layer 50 of the 1st base material part 2 are shown. In the region where the release layer 40 of the first base material part 2 is laminated, the aluminum vapor deposition layer 30, the adhesive layer 50, and the release layer 40 remain attached to the second base material part 3, In the region where the release layer 40 of the first base material part 2 is not laminated, the aluminum vapor deposition layer 30 and the adhesive layer 50 are peeled off from the second base material part 3 together with the first base material part 2.

  Then, in the 1st base material part 2 which peeled from the 2nd base material part 3, the part with which the aluminum vapor deposition layer 30 was laminated | stacked, and the part from which the aluminum vapor deposition layer 30 peeled from the 1st base material part 2 are included. It will be mixed. Thereby, the difference in color by the presence or absence of the aluminum vapor deposition layer 30 according to the coating pattern of the peeling layer 40 arises in the 1st base material part 2. FIG.

  Then, even if it is going to stick the 1st base material part 2 which peeled from the 2nd base material part 3 to the 2nd base material part 3 again, the coating pattern of the peeling layer 40 is a fine thing, and 1st group The material part 2 and the 2nd base material part 3 cannot be stuck cleanly, and the part with the aluminum vapor deposition layer 30 still laminated | stacked and the aluminum vapor deposition layer 30 peeled from the 1st base material part 2. Since the boundary part with the part does not become clean according to the coating pattern of the release layer 40, as shown in FIG. A gap 31 between which the aluminum vapor deposition layer 30 is not interposed is formed between the portion 3 and the portion 3. Thereby, it is detected that, after the first base material portion 2 and the second base material portion 3 are attached, they are illegally peeled off and attached again due to the color difference in the gap 31 in particular. It will be.

  Next, the operation when reading the two-dimensional code 12 will be described.

  FIG. 5 is a diagram for explaining the operation when the two-dimensional code 12 of the security band 1 shown in FIG. 1 is read.

  In the security band 1 shown in FIG. 1, in the state where the first base material portion 2 and the second base material portion 3 are properly attached, the two displayed on the first base material portion 2 of the transparent film 10. When infrared rays are irradiated from the first base material part 2 side to read the dimension code 12, as shown in FIG. 5 (a), the irradiated infrared rays are converted into infrared rays in the two-dimensional code 12. The two-dimensional code 12 is correctly recognized by being absorbed by being made of an absorbing material and being reflected by the aluminum vapor deposition layer 30 in other regions and detecting the reflected wave.

  On the other hand, if it peels after the 1st base material part 2 and the 2nd base material part 3 are stuck, as above-mentioned, the aluminum vapor deposition layer 30 of the 1st base material part 2 will be destroyed, Then, Even if the 1st base material part 2 which peeled from the 2nd base material part 3 was stuck on the 2nd base material part 3 again, the 1st base material part 2 and the 2nd base material part 3 which were stuck again, A gap 31 in which the aluminum vapor deposition layer 30 is not interposed is formed between the two. Therefore, as shown in FIG. 5 (b), when infrared rays are irradiated from the first base material part 2 side to read the two-dimensional code 12, in the gap 31 generated by the aluminum vapor deposition layer 30 being destroyed. Transmits infrared rays without reflecting. In that case, in the 2nd base material part 3 stuck on the 1st base material part 2, when the 1st base material part 2 is stuck on the whole surface of the area | region which opposes the display area of the two-dimensional code 12. Since the solid print layer 13 is laminated, the infrared rays transmitted through the gap 31 generated by the destruction of the aluminum vapor deposition layer 30 are also absorbed by the solid print layer 13. Thereby, even if the reflected infrared reflected wave is detected, the reflected wave is different from the reflected wave by the two-dimensional code 12, and the two-dimensional code 12 cannot be recognized.

  Thus, in the security band 1 of the present embodiment, when the first base material portion 2 and the second base material portion 3 are peeled off after being adhered, the aluminum vapor deposition layer 30 is destroyed. When infrared light is irradiated from the first base material part 2 side in order to read the two-dimensional code 12 in a state where the first base material part 2 and the second base material part 3 are improperly attached, the irradiated infrared light Is absorbed not only in the two-dimensional code 12 but also in the solid printed layer 13 of the second base material portion 3, and even if the reflected infrared wave is detected, the reflected wave is reflected by the two-dimensional code 12. Are different, thereby making the two-dimensional code 12 unrecognizable.

  In addition, when the aluminum vapor deposition layer 30 is peeled from the state in which the first base material part 2 and the second base material part 3 are adhered by pattern coating the release agent on the transparent film 10, Although it will be destroyed over the whole surface, when it peels from the state which the 1st base material part 2 and the 2nd base material part 3 were stuck, at least the area | region which opposes the two-dimensional code 12 What is necessary is just to be comprised so that a part of may be destroyed.

  Moreover, in this embodiment, although the aluminum vapor deposition layer 30 laminated | stacked by vapor-depositing aluminum on the transparent film 10 was mentioned as an example as a metal layer, it demonstrated using gold | metal | money and silver ink. Also good.

  Further, as long as the solid printing layer 13 contains carbon, the color of the ink is not limited to black, but may be cyan, magenta, yellow, and black containing carbon. Moreover, in the 2nd base material part 3, you may use what contained carbon as the ink which comprises the printing layers 21 and 22. FIG. However, only the region facing the two-dimensional code 12 needs to be laminated with the print layers 21 and 22 using an ink not containing carbon.

  In this embodiment, as shown in FIG. 6, a cushion layer 70 having a property of irreversibly elastically changing between the aluminum vapor deposition layer 30 and the adhesive layer 50 is laminated on the security band 1 shown in FIG. 1. This is a security band 101.

  The security band 101 of this embodiment is used in the same manner as that shown in FIG. 1, but when the first base material part 2 and the second base material part 3 are attached and peeled off, Although the aluminum vapor deposition layer 30 is destroyed, the cushion layer 70 is laminated, so that the aluminum vapor deposition layer 30 is not stuck to the second base material portion 3 even in the region where the release layer 40 is laminated. However, because the aluminum vapor deposition layer 30 is broken in the same manner as shown in FIG. 1, infrared rays are transmitted without being reflected in the portion where the aluminum vapor deposition layer 30 is broken, and the second base material portion 3 The solid print layer 13 absorbs the two-dimensional code 12 so that it cannot be recognized.

(Third embodiment)
FIG. 7 is a diagram showing an example of a security band having the third embodiment of the fraud prevention structure of the present invention, where (a) is a front view and (b) is an AA ′ diagram shown in (a). Sectional drawing (c) is a figure which shows the structure of the surface of the transparent film 10. FIG.

  As shown in FIG. 7, this embodiment is a belt-like security band 201 in which the first base material portion 202 and the second base material portion 203 are continuously integrated as shown in FIG. 1. .

  The security band 201 has a bar code 212 that is a machine-reading code displayed in a region that becomes the first base material portion 202 on one surface of the band-shaped transparent film 10 that becomes the base base material, and a second base material. A solid print layer 13 serving as an absorption layer is laminated in a region serving as the portion 203. The bar code 212 and the solid print layer 13 are displayed and laminated by printing using an ink containing carbon which is an infrared absorbing material. On the surface on which the barcode 212 of the transparent film 10 is displayed and the solid printing layer 13 is laminated, the printing layer 21 made of colored ink that does not contain an infrared absorbing material is laminated. Although the barcode 212 is concealed by the print layer 21, the code recognition unit 202 a facing the barcode 212 can be recognized by the information displayed by the print layer 21.

  As in the case shown in FIG. 1, the release layer 40 is partially laminated on the surface of the transparent film 10 opposite to the barcode 212 and the solid print layer 13 by applying the release agent in a pattern. ing. Further, an aluminum vapor deposition layer 30 serving as a metal layer is laminated on the entire surface of the surface of the transparent film 10 opposite to the barcode 212 and the solid print layer 13 by covering the release layer 40 with aluminum. ing.

  The adhesive layer 50 is laminated on the entire surface of the aluminum vapor-deposited layer 30 opposite to the laminated surface with the transparent film 10 by applying an adhesive or an adhesive, and the adhesive layer 50 is interposed therebetween. The release paper 60 is attached so as to be peelable.

  In the release paper 60, a slit 61 penetrating the front and back is formed at a boundary portion between the first base material portion 2 and the second base material portion 3.

  Below, the usage method of the security band 201 comprised as mentioned above is demonstrated.

  FIG. 8 is a diagram illustrating a usage state of the security band 201 illustrated in FIG. 7.

  When using the security band 201 shown in FIG. 7, first, the region on the first base material portion 202 side is peeled off through the slit 61 in the release paper 60, and the adhesive layer 50 in the first base material portion 202. To express.

  Then, as shown in FIG. 8, it is wrapped around the delivery 205 so that the release paper 60 is on the inside, and the printed layer 21 of the second base material portion 203 is laminated on the surface of the adhesive layer 50 that is exposed. The 1st base material part 2 is stuck to.

  Then, when the 1st base material part 202 and the 2nd base material part 203 peel, the aluminum vapor deposition layer 30 will be destroyed like what was shown in FIG. Thereby, even if the 1st base material part 202 peeled from the 2nd base material part 203 is affixed again on the 2nd base material part 203 after that, in order to read barcode 212 in that state, the 1st base material part When infrared rays are irradiated from the side of the unit 202, the irradiated infrared rays are absorbed by the barcode 212, and in the region where the aluminum vapor deposition layer 30 is broken, the infrared rays are transmitted without being reflected. It is absorbed in the solid print layer 13 laminated on the material part 203. For this reason, even if the reflected wave of the irradiated infrared ray is detected, the reflected wave is different from the reflected wave by the barcode 212, and the barcode 212 cannot be recognized.

FIG. 9 is a view showing an example of a label used in the fourth embodiment of the fraud prevention structure of the present invention, where (a) is a front view and (b) is an AA ′ shown in (a). Sectional drawing (c) is a figure which shows the structure of the surface of the transparent film 10. FIG.

  As shown in FIG. 9, the label in the present embodiment is the first base material portion in the present invention, and, like the first base material portion 2 shown in FIG. A two-dimensional code 12 serving as a machine-reading code is displayed on one surface of the sheet, and a printed layer 21 made of colored ink that does not contain an infrared absorbing material is laminated in a state of concealing the two-dimensional code 12, Furthermore, it is the security label 301 by which the peeling layer 40, the aluminum vapor deposition layer 30 used as a metal layer, and the sticking layer 50 are each laminated | stacked on the other surface of the transparent film 10, and the peeling paper 60 is stuck so that peeling is possible.

  The two-dimensional code 12 is displayed and laminated on one surface of the transparent film 10 by printing using an ink containing carbon that is an infrared absorbing material.

  The release layer 40 is partially laminated on the surface of the transparent film 10 opposite to the two-dimensional code 12 by patterning a release agent. The aluminum vapor deposition layer 30 is laminated by depositing aluminum on the entire surface of the transparent film 10 opposite to the two-dimensional code 12 so as to cover the release layer 40. The adhesive layer 50 is laminated by applying a pressure-sensitive adhesive or an adhesive to the entire surface of the aluminum vapor deposition layer 30 on the surface opposite to the laminated surface with the transparent film 10, and this adhesive layer. The release paper 60 is attached to be peelable through 50.

  Below, the usage method of the security label 301 comprised as mentioned above is demonstrated.

  10A and 10B are diagrams for explaining a method of using the security label 301 shown in FIG. 9, wherein FIG. 10A is a surface view of a printed material to which the security label 301 shown in FIG. 9 is attached, and FIG. 9A is a front view showing a state where the security label 301 shown in FIG. 9 is attached to the printed matter shown in FIG. 9A. FIG. 9C is an illustration showing that the security label 301 shown in FIG. 9 is attached to the printed matter shown in FIG. It is a fragmentary sectional view which shows the state made.

  The printed matter to which the security label 301 shown in FIG. 9 is attached serves as the second base material portion in the present invention, and as shown in FIG. 10A, a part of one surface of the sheet 305a. In this area, a solid print layer 313 is laminated by printing using an ink containing carbon which is an infrared absorbing material.

  When the security label 301 shown in FIG. 9 is used, the release paper 60 is peeled to expose the adhesive layer 50, and as shown in FIG. 10 (b), the printed matter 305 shown in FIG. 10 (a). It is used by sticking with the sticking layer 50 on the solid printing layer 313. That is, in the fraud prevention structure according to this embodiment, the first base material portion and the second base material portion are configured as separate bodies.

  In a state where the security label 301 is stuck on the solid print layer 313 of the printed matter 305, as shown in FIG. 10C, the display area of the two-dimensional code 12 of the security label 301 and the solid print layer of the printed matter 305 are displayed. 313 will face. That is, in the printed matter 305, when the security label 301 is attached, the solid print layer 13 is laminated on the entire surface of the region facing the display region of the two-dimensional code 12. In this state, the two-dimensional code 12 is read and recognized by placing the barcode reader on the security label 301.
