Description

The present invention relates to a tamper detection label that is attached to a detection target and detects tampering with the detection target.

Conventionally, cable ties are used to prevent unauthorized opening of cases, etc. Cable ties are configured, for example, by connecting a band portion with a series of small teeth formed thereon and a head portion with a hole. Then, by inserting the band portion through the hole provided in the head portion, a locking portion provided inside the hole engages with the teeth of the band portion, and a locked state is established in which the band portion cannot be removed in the direction opposite to the insertion direction. Once in the locked state, the lock cannot be released unless the band portion or head portion is cut (for example, see Patent Document 1).

By using such a cable tie, the band portion of the cable tie is inserted through the holes provided in the body and lid of the case, and then the band portion is inserted through the hole in the cable tie, thereby preventing unauthorized opening of the case.

JP 2013-252169 A

Although the cable ties described above are configured to be bendable, they require a certain degree of stiffness in order to maintain the locked state with the teeth formed on the band portion. For this reason, the band portion is generally often made of plastic having a certain thickness, and the band portion also becomes thicker and stiffer depending on the height of the teeth. For this reason, when objects to be detected with cable ties attached are stacked for storage to prevent unauthorized opening, the cable ties are bulky and get in the way, making it difficult to stack the objects neatly, and making it difficult to handle the objects when storing them.

In addition, depending on the shape of the teeth of the band and the locking part of the head, if the band is pulled with a strong force in the opposite direction to the insertion direction, it may be possible to remove the band from the head without cutting it. In that case, the object to be detected with the cable tie attached may be illegally opened, and the cable tie removed from the object to be detected may then be reattached to the object, leaving no trace of illegal opening.

The present invention was made in consideration of the problems inherent in the conventional technology described above, and aims to provide a tamper detection label that, when attached to a detectable object, can detect tampering with the detectable object without making the detectable object difficult to handle.

In order to achieve the above object, the present invention provides
A tamper detection label that is attached to a detection target and detects tampering with the detection target,
a band-shaped sheet base material including a fraud detection section and a roll-up section that rolls up a part of the detected object when the fraud detection label is attached to the detected object and is partly attached to the fraud detection section, the band-shaped sheet base material being connected in the longitudinal direction;
a release layer laminated on one surface of the fraud detection unit in the shape of a predetermined latent image pattern;
The device has an adhesive layer laminated over the entire surface of the peel-off layer of the fraud detection unit, covering the peel-off layer.

In the present invention configured as described above, the wrapping portion wraps around a part of the object to be detected, and a part of the wrapping portion is attached to the tamper detection portion, thereby attaching the tamper detection label to the object to be detected. After that, in order to open the object to be detected, the part of the wrapping portion attached to the tamper detection portion must be peeled off from the tamper detection portion. When a part of the wrapping portion is peeled off from the tamper detection portion, the release layer laminated on one side of the tamper detection portion is peeled off from the adhesive layer, and a latent image pattern due to the release layer is revealed, thereby detecting that the object to be detected has been opened. In this case, the tamper detection portion and the wrapping portion are made of a sheet base material, and the configuration for detecting tampering of the object to be detected is that a latent image pattern is revealed by the release layer when a part of the wrapping portion is peeled off from the tamper detection portion. Therefore, when attached to the object to be detected, the tamper detection label does not become bulky and get in the way, and tampering of the object to be detected without making it difficult to handle the object to be detected.

In addition, if the width of the roll-up portion in the short direction of the sheet base material is narrower than the width of the fraud detection portion in the same direction, when a part of the roll-up portion is attached to the fraud detection portion, the part of the roll-up portion can be wrapped by the fraud detection portion.

A possible configuration for a detectable object with a fraud detection label attached as described above is one in which the object has two members, at least a portion of which separates when the object is opened, and each of the two members is provided at the separated portion and has a hole through which the roll-up portion is inserted, the roll-up portion is inserted into the two holes, and at least a portion of the area from the portion inserted into the hole to the end opposite the fraud detection portion is sandwiched between the fraud detection portion and the detectable object, and the fraud detection portion is affixed to the detectable object by an adhesive layer. In such a configuration, if the fraud detection label is affixed to the detectable object with the roll-up portion conforming to the surface of the detectable object, the fraud detection label will not protrude significantly from the detectable object, will not get in the way during storage, and will not get caught on other items.

A possible configuration for a detectable object to which a tamper detection label as described above is attached is one in which the object has two members, at least a portion of which separates when the object is opened, and each of the two members is provided at the separated portion and has a hole through which the roll-up portion is inserted, the roll-up portion is inserted into the two holes, and at least a portion of the area from the portion inserted into the hole to the end opposite the tamper detection portion is wrapped in the tamper detection portion.

According to the present invention, a tamper detection section for detecting tampering of a detectable object and a roll-up section that rolls up a part of the detectable object and is affixed to the tamper detection section when the tamper detection label is attached to the detectable object are connected in the longitudinal direction as a strip-shaped sheet base material, and the configuration for detecting tampering of the detectable object is such that a latent image pattern is revealed by the peel-off layer when a part of the roll-up section is peeled off from the tamper detection section to open the detectable object. Therefore, when attached to the detectable object, the tamper detection label does not become bulky and get in the way, and tampering of the detectable object can be detected without making the detectable object difficult to handle.

In addition, when the width of the roll-in portion in the short direction of the sheet base material is narrower than the width of the fraud detection portion in the same direction, it becomes easier for part of the roll-in portion to be wrapped by the fraud detection portion.

A possible configuration for a detectable object with a fraud detection label attached as described above is one in which the object has two members, at least a portion of which separates when the object is opened, and each of the two members is provided at the separated portion and has a hole through which the roll-up portion is inserted, the roll-up portion is inserted into the two holes, and at least a portion of the area from the portion inserted into the hole to the end opposite the fraud detection portion is sandwiched between the fraud detection portion and the detectable object, and the fraud detection portion is attached to the detectable object by an adhesive layer. In such a configuration, the fraud detection label can be attached to the detectable object with the roll-up portion conforming to the surface of the detectable object, so that the fraud detection label does not protrude significantly from the detectable object, does not get in the way during storage, and can be prevented from getting caught on other items.

Below, an embodiment of the present invention will be described with reference to the drawings.

Figure 1 shows one embodiment of the tamper detection label of the present invention, where (a) is a surface view, (b) is a cross-sectional view taken along the line A-A' shown in (a), and (c) is a diagram showing the shape of the release layer 20 on the back surface of the film substrate 10.

As shown in FIG. 1, this embodiment is a tamper detection label 1 in which a release layer 20 is laminated on one side of a film substrate 10, an adhesive layer 30 is laminated covering the release layer 20, and a film substrate 40 and a release paper 50 are laminated and attached to the side of the adhesive layer 30 opposite the film substrate 10.

The film substrate 10 is the sheet substrate in the present invention, and is made of a transparent or translucent film, so that the color of one side can be seen from the other side. The film substrate 10 has a strip shape with the fraud detection section 1a and the roll-up section 1b connected in the longitudinal direction. Although the film substrate 10 has a strip shape, the width in the short direction is approximately T-shaped, with the width W2 of the roll-up section 1b being narrower than the width W1 of the fraud detection section 1a.

As shown in Figures 1(b) and 1(c), one side of the sheet substrate 10 is partially laminated over its entire surface with a release layer 20, which is made of a release agent such as transparent silicone, applied in the shape of a latent image pattern that appears when the fraud detection label 1 is peeled off after being attached to an adherend.

The adhesive layer 30 is laminated by applying an adhesive to the entire surface of the sheet substrate 10 on which the release layer 20 is laminated, covering the release layer 20. The adhesive layer 30 is made of any color, such as blue, red, or black, and has elasticity.

Furthermore, on the surface of the adhesive layer 30 opposite the film substrate 10, a film substrate 40 is laminated and attached in an area facing the roll-up portion 1b of the sheet substrate 10, and a release paper 50 is removably attached in an area facing the fraud detection portion 1a of the sheet substrate 10. As shown in FIG. 1(b), the size of the release paper 50 may be set so that a part of it overlaps with a part of the film substrate 40, making it easier to peel off the release paper 50 when using the fraud detection label 1, but the size of the release paper 50 need only cover at least the area of the adhesive layer 30 that is not covered by the film substrate 40. Alternatively, a configuration may be adopted in which the adhesive layer 30 loses its adhesive force by applying varnish to the adhesive layer 30 instead of the film substrate 40.

The fraud detection label 1 thus constructed has a sheet substrate 10 made of a transparent or translucent film, so that the color of the adhesive layer 30 is visible from the surface of the sheet substrate 10 side. As a result, when the fraud detection label 1 is fraudulently peeled off from the adherend, the latent image pattern created by the peel-off layer 20, which will be described later, becomes visible.

The following describes how to use the fraud detection label 1 configured as described above.

First, we will explain how to attach the tamper detection label 1 to the object to be detected for tampering.

Figure 2 is an external perspective view showing an example of a detection target whose tampering is detected by the tamper detection label 1 shown in Figure 1.

As shown in FIG. 2, an example of an object to be detected for tampering by the tamper detection label 1 shown in FIG. 1 is a container 2, which is made up of a container 4 having an opening for storing items and a lid 3 attached to the opening of the container 4 so as to be freely opened and closed, as shown in FIG. 2. The container 2 shown in FIG. 2 has holes 3a and 4a on the lid 3 and the container 4, respectively, in areas that face each other when the lid 3 is closed and are separated when the lid 3 is open, for attaching the tamper detection label 1 shown in FIG. 1.

Figure 3 shows an example of the state in which the tamper detection label 1 shown in Figure 1 is attached to the container 2 shown in Figure 2, where (a) is an external perspective view and (b) is a view showing the area of the A-A' end face shown in (a) near the area where the tamper detection label 1 is attached.

When detecting tampering of the container 2 shown in FIG. 2 using the tamper detection label 1 shown in FIG. 1, first, as shown in FIG. 3, with the lid 3 closed, the wrapping portion 1b of the tamper detection label 1 is inserted through the holes 3a and 4a. Then, a portion of the area from the portion of the wrapping portion 1b inserted through the holes 3a and 4a to the end opposite the tamper detection portion 1a is sandwiched between the tamper detection portion 1a and the lid 3, and the tamper detection portion 1a is attached to the lid 3 by the adhesive layer 30. In this way, the lid 3 and the container 4 of the container 2 are wrapped in the wrapping portion 1b, and a portion of the wrapping portion 1b is attached to the tamper detection portion 1a, thereby attaching the tamper detection label 1 to the container 2. Furthermore, in this example, the tamper detection portion 1a is attached to the lid 3 with a portion of the wrapping portion 1b sandwiched between the lid 3 of the container 2 and the wrapping portion 1b.

In this way, when the tamper detection label 1 shown in Figure 1 is attached to the container 2, the container 2 cannot be opened unless the tamper detection label 1 is broken or the tamper detection portion 1a is peeled off from the lid 3 to separate the tamper detection portion 1a from the roll-up portion 1b.

In this case, the tamper detection label 1 has a peeling layer 20 laminated on one side of the film substrate 10, and an adhesive layer 30 laminated covering the peeling layer 20, and in the roll-up portion 1b, a film substrate 40 is laminated and attached to the surface of the film substrate 10 on which the peeling layer 20 and adhesive layer 30 are laminated, covering the peeling layer 20 and adhesive layer 30. Therefore, when the tamper detection label 1 is attached to the container 2 to detect tampering of the container 2 as described above, the tamper detection label 1 does not become bulky and get in the way compared to a cable tie, and the container 2 is prevented from becoming difficult to handle.

The length by which the fraud detection label 1 protrudes from the container 2 can be adjusted by changing the length and area of the wrapping portion 1b that is sandwiched between the fraud detection portion 1a and the lid 3. As shown in FIG. 3, by attaching the fraud detection portion 1a to the lid 3 by pulling both ends of the fraud detection label 1, the fraud detection label 1 can be attached to the container 2 so that the wrapping portion 1b fits along the surface of the container 2. This prevents the fraud detection label 1 from protruding too far from the container 2, does not get in the way during storage, and prevents it from getting caught on other items.

Next, we will explain the action that occurs when the tamper detection portion 1a is peeled off from the container 2 or the wrapping portion 1b in order to tamper with the container 2 to which the tamper detection label 1 is attached as described above.

Figure 4 is a cross-sectional view for explaining the state in which the tamper detection label 1 shown in Figure 1 is peeled off from the container 2 after being affixed to the container 2 as shown in Figure 3. Note that the tamper detection unit 1a has the roll-up portion 1b sandwiched between it and the lid 3 at one part, but for ease of explanation, Figure 4 shows only the part where the tamper detection unit 1a is directly affixed to the lid 3.

As shown in FIG. 4(a), when the fraud detection section 1a of the fraud detection label 1 is peeled off from the lid 3, as shown in FIG. 4(b), in the area where the peeling layer 20 is not laminated, the adhesive layer 30 peels off from the lid 3 together with the film substrate 10, and in the area where the peeling layer 20 is laminated, the adhesive layer 30 peels off from the peeling layer 20 because the adhesive layer 30 is attached to the lid 3 with a stronger adhesion force than the adhesion force to the peeling layer 20. Then, the part peeled off from the peeling layer 20 peels off from the lid 3 together with the film substrate 10 because the adhesive layer 30 has elasticity, breaks in a direction perpendicular to the lamination direction with the peeling layer 20, and is pulled by the part that remains laminated on the film substrate 10 and almost does not exist in the area facing the peeling layer 20.

When the fraud detection portion 1a of the fraud detection label 1 is completely peeled off from the lid 3, the adhesive layer 30 is present almost only in the area where the peel-off layer 20 is not laminated, as shown in FIG. 4(c).

In this case, in the area where the wrapping portion 1b of the fraud detection unit 1a was attached, when the fraud detection unit 1a is peeled off from the lid 3 as described above and at the same time the portion of the wrapping portion 1b that was sandwiched between the fraud detection unit 1a and the lid 3 and attached to the fraud detection unit 1a is peeled off from the fraud detection unit 1a, in the area where the wrapping portion 1b of the fraud detection unit 1a was attached, the adhesive layer 30 will be present almost only in the area where the peel-off layer 20 is not laminated, just like above.

Furthermore, as described above, when the tamper detection unit 1a is peeled off from the lid 3, if the portion of the wrapping portion 1b that was sandwiched between the tamper detection unit 1a and the lid 3 and attached to the tamper detection unit 1a remains attached to the tamper detection unit 1a, then by peeling off the tamper detection unit 1a and the wrapping portion 1b to open the container 2, the adhesive layer 30 will be present almost only in the area where the peel-off layer 20 is not laminated, even in the area where the wrapping portion 1b of the tamper detection unit 1a was attached.

Figure 5 is a surface view showing the state in which the fraud detection portion 1a of the fraud detection label 1 shown in Figure 1 has been peeled off from the lid 3 and the wrapping portion 1b.

When the fraud detection section 1a of the fraud detection label 1 shown in FIG. 1 is peeled off from the lid 3 and the roll-up section 1b as described above, when the fraud detection label 1 is viewed from the film substrate 10 side, the color of the adhesive layer 30 is visible through the film substrate 10 in the area of the fraud detection section 1a that does not face the peel-off layer 20 due to the presence of the adhesive layer 30, whereas the color of the adhesive layer 30 is not visible in the area facing the peel-off layer 20 of the fraud detection section 1a due to the absence of the adhesive layer 30. This results in the appearance of a latent image pattern 21 due to the peel-off layer 20, as shown in FIG. 5.

On the other hand, in the wrap-around portion 1b of the fraud detection label 1, the film substrate 40 is laminated over the entire surface on which the adhesive layer 30 is laminated, so that the wrap-around portion 1b is not attached to the lid 3, and as a result, the latent image pattern 21 due to the peel-off layer 20 as described above is not manifested.

Even if the entire or part of the film substrate 10 is printed, the color of the printing will be visible in the area facing the peel-off layer 20 of the fraud detection unit 1a, while in the area not facing the peel-off layer 20 of the fraud detection unit 1a, a color corresponding to the printing color of the film substrate 10 and the color of the adhesive layer 30 will be visible, and the latent image pattern 21 caused by the peel-off layer 20 will appear. For example, if the film substrate 10 is printed in red and the adhesive layer 30 is green, a red latent image pattern 21 will appear on a black background caused by the mixture of red and green.

Even if the rolled-up portion 1b of the tamper detection label 1, on which the latent image pattern 21 is thus revealed, is then inserted into the holes 3a and 4a, and the tamper detection portion 1a is reattached to the container 2 by sandwiching the rolled-up portion 1b between the label and the container 2, the latent image pattern 21 remains revealed because the adhesive layer 30 is no longer present in the area facing the peel-off layer 20, and it is possible to recognize that the tamper detection label 1 has been peeled off from the container 2 and that the container 2 has been tamper-opened.

In addition, when the fraud detection section 1a of the fraud detection label 1 is peeled off after being attached to the container 2 and the wrapping section 1b, the area of the adhesive layer 30 facing the peeling layer 20 peels off from the peeling layer 20 and breaks in a direction perpendicular to the lamination direction with the peeling layer 20. As a result, when the fraud detection label 1 is peeled off from the container 2, the entire adhesive layer 30 is peeled off from the container 2 together with the film substrate 10. As a result, after the fraud detection section 1a of the fraud detection label 1 is peeled off from the container 2, no part of the fraud detection label 1 remains on the container 2.

In this manner, in the present embodiment of the tamper detection label 1, if the tamper detection section 1a, which is affixed to the lid 3 of the container 2 by sandwiching the rolled-up section 1b, is tampered with and peeled off from the lid 3 and the rolled-up section 1b, the latent image pattern 21 by the peel-off layer 20 is revealed, making it possible to detect the tampered peeling off of the container 2 in order to open the container 2.

Figure 6 shows another example of the state in which the tamper detection label 1 shown in Figure 1 is attached to the container 2 shown in Figure 2, where (a) is an external perspective view and (b) is a view showing the area of the A-A' end face shown in (a) near the area where the tamper detection label 1 is attached.

When using the tamper detection label 1 shown in FIG. 1 to detect tampering of the container 2 shown in FIG. 2, first, with the lid 3 closed, insert the wrapping portion 1b of the tamper detection label 1 into the holes 3a, 4a as shown in FIG. 6. Then, it is also possible to make the tamper detection label 1 into a ring shape, and attach a portion of the area from the portion of the wrapping portion 1b inserted into the holes 3a, 4a to the end opposite the tamper detection portion 1a to the tamper detection portion 1a with the adhesive layer 30. In this way, in this example too, the tamper detection label 1 is attached to the container 2 by wrapping a portion of the lid 3 and the container 4 of the container 2 with the wrapping portion 1b, and attaching a portion of the wrapping portion 1b to the tamper detection portion 1a.

In this case, as described above, the width of the film substrate 10 in the short direction is narrower in the wrapped-in portion 1b than in the fraud detection portion 1a, so that the area of the wrapped-in portion 1b that is affixed to the fraud detection portion 1a can be wrapped by the fraud detection portion 1a by bending the fraud detection portion 1a in the short direction of the fraud detection label 1, as shown in FIG. 6. In this case, the fraud detection portion 1a wraps a portion of the wrapped-in portion 1b, which results in portions of the fraud detection portions 1a being affixed to each other.

In this way, the wrapping portion 1b of the tamper detection label 1 shown in Figure 1 is inserted through the lid 3 of the container 2 and the holes 3a, 4a of the container 4, and is affixed to the tamper detection portion 1a while being wrapped in the tamper detection portion 1a. Thereafter, the container 2 cannot be opened unless the tamper detection label 1 is broken or the tamper detection portion 1a is opened and the wrapping portion 1b is peeled off from the tamper detection portion 1a.

In this case, the tamper detection label 1 is configured such that a peeling layer 20 is laminated on one side of a film substrate 10, an adhesive layer 30 is laminated covering the peeling layer 20, and a film substrate 40 is laminated and attached to a part of the surface of the adhesive layer 30 opposite the film substrate 10. Therefore, when the tamper detection label 1 is attached to the container 2 to detect tampering of the container 2 as described above, the tamper detection label 1 does not become bulky and get in the way compared to a cable tie, and the container 2 is prevented from becoming difficult to handle. Also, in this example, the size of the loop formed by the tamper detection label 1 can be adjusted by changing the length and area of the wrapping portion 1b that is attached to the tamper detection portion 1a.

Even when the tamper detection label 1 is attached to the container 2 as described above, if the tamper detection section 1a is opened and the rolled-up section 1b is peeled off from the tamper detection section 1a in order to tamper-open the container 2 to which the tamper detection label 1 is attached, a latent image pattern created by the peel-off layer 20 will appear due to the same action as shown in Figure 4, and it will be possible to detect that the container 2 has been tamper-opened. At that time, the tamper detection section 1a wraps around a portion of the rolled-up section 1b, creating a portion where the tamper detection sections 1a are attached to each other, and so the latent image pattern created by the peel-off layer 20 will appear in that area as well.

Other Embodiments
Figure 7 shows another embodiment of the fraud detection label of the present invention, where (a) is a surface view, (b) is a cross-sectional view along the line A-A' shown in (a), and (c) is a view showing the shape of the peel-off layer 120 on the back surface of the film substrate 110.

As shown in FIG. 7, this embodiment is a fraud detection label 101 that differs from the one shown in FIG. 1 in that the width W2 of the roll-up portion 1b in the short direction of the film substrate 110 is narrower than the width W1 of the fraud detection portion 1a, but is L-shaped.

The tamper detection label 101 constructed as above can also be attached to the container 2 as shown in FIG. 1, as shown in FIG. 3 or FIG. 6, to detect that the container 2 has been tamper-evident. When attaching to the container 2 as shown in FIG. 6, instead of wrapping the area of the roll-up portion 1b attached to the tamper detection portion 1a around the tamper detection portion 1a as shown in FIG. 1, and creating areas where the tamper detection portions 1a are attached to each other, it is possible to fold the tamper detection portion 101a in half around the fold portion 111, and sandwich the roll-up portion 101b in the folded area of the tamper detection portion 101a.

Figure 8 shows another embodiment of the tamper detection label of the present invention, where (a) is a surface view, (b) is a cross-sectional view taken along the line A-A' shown in (a), and (c) is a diagram showing the shape of the release layer 220 on the back surface of the film substrate 210.

As shown in FIG. 8, this embodiment is a fraud detection label 201 that differs from that shown in FIG. 1 in that the fraud detection section 201a and the roll-up section 201b have the same width in the short direction of the film substrate 210.

The fraud detection label 201 configured as above can also be attached to the container 2 as shown in FIG. 1 as shown in FIG. 3 or FIG. 6 to detect that the container 2 has been tampered with. However, in the fraud detection label 201 of this embodiment, the widths of the fraud detection section 201a and the roll-up section 201b are equal in the short direction of the film substrate 210. Therefore, when attaching the fraud detection label 201 to the container 2 as shown in FIG. 3, it is necessary to attach the fraud detection section 201a to the lid 3 by sandwiching a part of the roll-up section 201b between the fraud detection section 201a and the lid 3 so that a part of the fraud detection section 201a does not overlap with the roll-up section 201b in the long direction of the fraud detection label 201. Also, when attaching the fraud detection label 201 to the container 2 as shown in FIG. 6, only a part of the roll-up section 201b is attached to the fraud detection section 201a and is not wrapped around the fraud detection section 201a.

In the above-mentioned embodiment, the adhesive layer 30, 130, 230 has elasticity, so that when the fraud detection section 1a, 101a, 201a of the fraud detection label 1, 101, 201 is peeled off from the roll-up section 1b, 101b, 201b or the lid 3, the adhesive layer 30, 130, 230 is peeled off from the roll-up section 1b, 101b, 201b or the lid 3 even in the area laminated on the peel-off layer 20, 120, 220, and does not remain on the roll-up section 1b, 101b, 201b or the lid 3. However, when the adhesive layer does not have elasticity, when the fraud detection section of the fraud detection label is peeled off from the roll-up section or the lid 3, the area of the adhesive layer laminated on the peel-off layer may remain on the roll-up section or the lid 3.

In the above-described embodiment, the film substrate 10, 110, 210 is made of a transparent or semi-transparent film, so that the color of the adhesive layer 30, 130, 230 is visible when viewed from the side opposite to the side on which the peeling layer 20, 120, 220 and the adhesive layer 30, 130, 230 are laminated. However, only the area of the film substrate 10, 110, 210 facing the peeling layer 20, 120, 220 may be transparent or semi-transparent, and the other areas may be colored the same color as the adhesive layer 30, 130, 230.

In the above-mentioned embodiment, the adhesive layer 30, 130, 230 is described as being of any color such as blue, red, black, etc., but it is also possible to use a transparent adhesive layer 30, 130, 230. In that case, it is possible to cover the entire surface of the base substrate 10, 110, 210 on which the peel-off layer 20, 120, 220 is laminated, laminate a colored cushion layer, and laminate the adhesive layer 30, 130, 230 on this cushion layer. In such a configuration, when the fraud detection unit 1a, 101a, 201a is peeled off from the lid 3 or the wrapping portion 1b, 101b, 201b of the container 2 after being attached to the container 2 as shown in FIG. 3 and FIG. 6, the cushion layer is peeled off from the peeling layer 20, 120, 220, and when viewed from the side opposite to the side on which the peeling layer 20, 120, 220 and the adhesive layer 30, 130, 230 are laminated, the color of the cushion layer is visible through the base material 10, 110, 210 in the area not facing the peeling layer 20, 120, 220, while in the area facing the peeling layer 20, 120, 220, a gap is generated between the cushion layer and the peeling layer 20, 120, 220, making it difficult to see the color of the cushion layer through the base material 10, 110, 210, and thus a latent image pattern due to the peeling layer 20, 120, 220 is revealed.

In the above-described embodiment, the lid 3 and container 4 of the container 2 are provided with holes 3a and 4a for attaching the tamper detection labels 1, 101, and 201 to the container 2, respectively, and the wrapping parts 1b and 101b are inserted into the holes 3a and 4a. However, if the lid 3 and container 4 are made of a mesh or other material, through which the wrapping parts 1b, 101b, and 201b can be inserted and which have a configuration capable of wrapping a part of the object to be detected, there is no need to provide holes.

In the above-mentioned embodiment, the tamper detection label 1, 101, 201 shown in FIG. 1, 7, or 8 is attached to the container 2 shown in FIG. 2 to detect tampering of the container 2. However, the tamper detection label 1, 101, 201 shown in FIG. 1, 7, or 8 may be attached to a bag that is opened and closed by a zipper with two pull tabs to detect tampering of the bag. In that case, when the bag is closed, the roll-up parts 1b, 101b, and 201b are inserted into holes provided in the two pull tabs, and a part of the area from the part of the roll-up parts 1b, 101b, and 201b that is inserted into the holes to the end on the opposite side to the tamper detection parts 1a, 101a, and 201a is attached to the tamper detection part 1a by the adhesive layer 30, 130, and 230, as shown in FIG. 6.
