JP6276515B2 - Peel detection label - Google Patents

Description

  The present invention relates to a peeling detection label that can detect peeling from an adherend after being attached to the adherend, and more particularly to a technique that enables clean peeling from an adherend after use.

  In general, when temperature control conditions such as chemicals and specimens are severe, they are often stored and transported in a cool box in which the internal temperature is kept constant. In such a cold box, since the internal temperature changes when opened, a mechanism for detecting that the package has been opened illegally is necessary in terms of management of chemicals and specimens.

  Therefore, when the label on which the two sheets are detachably attached is pasted on the adherend across the opening, and then peeled off from the adherend, the two sheets are peeled off. Thus, for example, Patent Document 1 discloses a technique for detecting that the adherend has been opened illegally. Further, the label disclosed in Patent Document 1 has an easy-peel structure at the end thereof, so that it can be peeled cleanly from the adherend after use.

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

(First embodiment)
1A and 1B are diagrams showing a first embodiment of a peeling detection label according to the present invention, in which FIG. 1A is a front view, FIG. 1B is a cross-sectional view along AA ′ shown in FIG. Is a back view.

  As shown in FIG. 1, the peeling detection label in the present embodiment is configured by adhering a band-shaped film sheet 10 serving as a first sheet and a band-shaped film sheet 40 serving as a second sheet by an adhesive layer 20 a. Yes.

  The film sheet 10 has a pressure-sensitive adhesive layer 20a laminated thereon by applying a colored pressure-sensitive adhesive on the entire surface of the film sheet 40, and a peeling substrate 60 is formed at both ends in the longitudinal direction. It is stuck. With this peeling substrate 60, the film sheet 10 and the film sheet 40 are not attached to each other at both ends in the longitudinal direction. A print layer 11 is laminated on the surface of the film sheet 10 opposite to the adhesive layer 20a by printing information.

  The film sheet 40 is formed with a slit 41 serving as a dividing line at a central portion in the longitudinal direction, and is divided into two regions by the slit 41. A release layer 30 is laminated on a part of the adhesive surface of the film sheet 40 with the film sheet 10. The peeling layer 30 is laminated | stacked on the pattern according to the information which showed having peeled when the film sheet 10 and the film sheet 40 were peeled, and the adhesive force with respect to the film sheet 40 is adhesive force with the adhesion layer 20a. It has become stronger. In addition, the adhesive layer 20 a has a stronger adhesive force with the film sheet 40 than an adhesive force with the film sheet 10. A pressure-sensitive adhesive is applied to the entire surface of the film sheet 40 opposite to the surface to be bonded to the film sheet 10, and the pressure-sensitive adhesive layer 20 b is laminated on the entire surface. The peeling base material 70 which comprises a part is stuck. This adhesion layer 20b has a stronger adhesion to the adherend than the adhesion of the adhesion layer 20a to the film sheet 10. In addition, a release layer 52 is laminated on the base substrate 51 on the entire surface excluding the area where the release substrate 70 is attached, on the surface opposite to the attachment surface of the film sheet 40 to the film sheet 10. The release sheet 50 thus formed is stuck so as to be peelable in a direction in which the release layer 52 faces the adhesive layer 20b. That is, the release sheet 50 is divided into two regions across the region where the release substrate 70 is adhered.

  Below, the usage method of the peeling detection label 1 comprised as mentioned above is demonstrated.

  First, a method for attaching the peel detection label 1 shown in FIG. 1 to an adherend will be described.

  FIG. 2 is a view for explaining a method of attaching the peeling detection label 1 shown in FIG. 1 to an adherend.

  When sticking the peeling detection label 1 shown in FIG. 1 to an adherend, the peeling sheet 50 is first peeled as shown in FIG. The release sheet 50 can be peeled off from the film sheet 40 because the release layer 52 is laminated on the base substrate 51 so that the release sheet 50 can be peeled off. At this time, since both end portions in the longitudinal direction of the film sheet 40 are not adhered to the film sheet 10 by the base material 60 for peeling, an attempt is made to peel off the release sheet 50 using both end portions in the longitudinal direction of the film sheet 40 as peeling start ends. Then, there exists a possibility that the film sheet 10 and the film sheet 40 may try to peel. Therefore, it is preferable to peel from the film sheet 40 by using the peeling substrate 70 side of the peeling sheet 50 as a peeling start end.

  Then, the adhesive layer 20b laminated | stacked on the surface on the opposite side to the sticking surface with the film sheet 10 of the film sheet 40 appears, and as shown to FIG. It can stick to the container 90 which becomes.

  As shown in FIG. 2C, the container 90 in the present embodiment includes a lid portion 91 and a main body portion 92, and has a structure that can be opened by lifting the lid portion 91. The peeling detection label 1 is pasted across the unsealing part 93 which becomes a boundary part with the part 92.

  Next, as shown in FIG. 2, a method of use when opening the container 90 to which the peeling detection label 1 is stuck and an action at that time will be described.

  FIG. 3 is a view for explaining a method of use when opening the container 90 to which the peeling detection label 1 is stuck as shown in FIG. 2 and the action at that time.

  When opening the container 90 to which the peeling detection label 1 is attached as shown in FIG. 2B, the longitudinal ends of the film sheets 10 and 40 are peeled off as shown in FIG. It peels from the container 90 as a start end. Then, as shown in FIG. 3A, the film sheet 10 and the film sheet 40 are not attached to each other by the peeling substrate 60 at both longitudinal ends. The film sheet 10 and the film sheet 40 are about to be peeled off in a state where the base material 60 is adhered to the film sheet 10 by the adhesive layer 20a.

  Moreover, since the adhesive force with respect to the container 90 of the adhesion layer 20b is stronger than the adhesive force with the film sheet 10 of the adhesion layer 20a, the film sheet 10 and the film sheet 10 remain adhered to the container 90. The film sheet 40 peels off. Then, since the adhesive force with the film sheet 40 of the adhesive layer 20a is stronger than the adhesive force with the film sheet 10, the adhesive layer 20a is applied to the film sheet 40 as shown in FIG. It peels from the film sheet 10 with the laminated state. Moreover, in the area | region where the peeling layer 30 of the film sheet 40 was laminated | stacked, as shown in FIG.3 (b), the adhesive layer 20a peeled from the film sheet 40 by the peeling layer 30, and was laminated | stacked on the film sheet 10 Will remain.

  In this way, when the peeling detection label 1 is peeled from the container 90 with the longitudinal ends of the film sheets 10 and 40 as peeling start ends, the film sheet 40 is housed as shown in FIG. The film sheet 10 and the film sheet 40 are peeled off while being adhered to the container 90, and the adhesive layer 20a remains laminated on the film sheet 40 in the region where the peeling layer 30 of the film sheet 40 is not laminated. In the region where the release layer 30 is laminated, the adhesive layer 20a peels from the film sheet 40. In addition, the film sheet 10 and the film sheet 40 are in a state where they are not attached to each other by the peeling base material 60 at both ends in the longitudinal direction, so that either end in the longitudinal direction of the film sheets 10 and 40 Even when peeled from the part, the same effect occurs.

  Then, since the adhesive layer 20a is made of a colored adhesive, unsealing information 2 having a pattern corresponding to the release layer 30 appears by the adhesive layer 20a as shown in FIG. 3 (d). Since the film sheet 40 is divided into two regions by the slit 41 formed in the central portion in the longitudinal direction, when the peeling detection label 1 is stuck to the container 90 across the opening portion 93, the film sheet One of the two regions divided by 40 slits 41 is stuck to the lid portion 91 of the container 90 and the other is stuck to the main body portion 92, and the film sheet 40 is placed in the container 90. The container 90 can be opened while being attached to the container. Thus, when it is going to peel the peeling detection label 1 from the container 90 in order to open the container 90, when the film sheet 10 and the film sheet 40 peel and the opening information 2 appears, the container It is possible to detect that 90 is illegally opened.

  Next, the peeling method from the container 90 of the peeling detection label 1 is demonstrated.

  FIG. 4 is a view for explaining a peeling method of the peeling detection label 1 from the container 90 after the container 90 is opened as shown in FIG.

  In the state where the container 90 is opened as shown in FIG. 3, the film sheet 40 is adhered to the container 90 by the adhesive layer 20b, but the region along the slit 41 of the film sheet 40 is for peeling. The base material 70 is stuck, and, thereby, the region along the slit 41 of the film sheet 40 is not stuck to the container 90. Therefore, as shown in FIG. 4A, the two regions of the film sheet 40 can be peeled from the container 90 with the peeling base material 70 as the peeling start end.

  Thereafter, by peeling the two regions of the film sheet 40 from the container 90, the peel detection label 1 can be completely peeled from the container 90 as shown in FIG.

  Thus, in this embodiment, after the film sheet 10 and the film sheet 40 are peeled off and peeling from the container 90 is detected, the film sheet 40 that is still attached to the container 90. Is peeled off from the container 90 with the peeling base material 70 attached to the area along the slit 41 dividing the film sheet 40 into two areas as the peeling start end, the film sheet 10 and the film sheet 40 If it is not after peeling, the peeling detection label 1 cannot be peeled from the container 90 by using the peeling base material 70, and thereby, it can be detected that the peeling is illegally peeled from the container 90. Can also be peeled cleanly from the container 90 after use.

  In addition, in this form, although the peeling base material 70 stuck to the film sheet 40 by the adhesion layer 20b was used as a non-sticking part, using the peeling sheet 50 as the peeling base material 70 is also considered. It is done. In that case, it can be considered that only the region along the slit 41 of the release sheet 50 is attached to the film sheet 40 so that the base substrate 51 faces the adhesive layer 20b.

  In this embodiment, the adhesive layer 20 b is laminated on the entire surface of the film sheet 40 opposite to the film sheet 10, but in the region along the slit 41, the peeling substrate 70 is attached to the film sheet 40. The adhesive layer 20b needs to be laminated in order to keep the release sheet 50 in a region facing the release sheet 50, but is sufficient to attach the release sheet 50 to the film sheet 40 in a peelable manner. If there is, the adhesive layer 20b may be laminated only on a part including both ends of the film sheet 40 in the longitudinal direction.

(Second Embodiment)
FIGS. 5A and 5B are diagrams showing a second embodiment of the peeling detection label of the present invention, in which FIG. 5A is a front view, FIG. 5B is a cross-sectional view taken along line AA ′ shown in FIG. Is a back view.

  As shown in FIG. 5, the peel detection label in this embodiment includes a slit 141 formed in the film sheet 140 with respect to that shown in the first embodiment, and an adhesive layer is provided in the region along the slit 141. 120b is not laminated | stacked, and the point by which the base material 70 for peeling is not stuck on the film sheet 140 in connection with it is different. Thereby, in this form, the field in alignment with slit 141 of film sheet 140 serves as a non-adhesion part.

  Below, the usage method of the peeling detection label 101 comprised as mentioned above is demonstrated.

  First, a method for attaching the peeling detection label 101 shown in FIG. 5 to an adherend will be described.

  FIG. 6 is a diagram for explaining a method of attaching the peeling detection label 101 shown in FIG. 5 to an adherend.

  When sticking the peeling detection label 101 shown in FIG. 5 to an adherend, first, the peeling sheet 150 is peeled as shown in FIG. The release sheet 150 can be peeled from the film sheet 140 because the release layer 152 is laminated on the base substrate 151 so as to be peeled off. At this time, since both end portions in the longitudinal direction of the film sheet 140 are not attached to the film sheet 110 by the base material for peeling 160, an attempt is made to peel off the release sheet 150 using both end portions in the longitudinal direction of the film sheet 140 as peeling start ends. Then, the film sheet 110 and the film sheet 140 may be peeled off. Therefore, it is preferable to peel from the film sheet 140 with the slit 141 side of the release sheet 150 as the peeling start end.

  Then, the adhesive layer 120b laminated | stacked on the surface on the opposite side to the sticking surface with the film sheet 110 of the film sheet 140 appears, and as shown to FIG. The container 190 can be attached.

  As shown in FIG. 6C, the container 190 in this embodiment is composed of a lid 191 and a main body 192, and has a structure that can be opened by lifting the lid 191. The lid 191 and the main body The peeling detection label 101 is pasted across the unsealed part 193 which is a boundary part with the part 192.

  Next, as shown in FIG. 6, a method of use when opening the container 190 to which the peeling detection label 101 is stuck and an action at that time will be described.

  FIG. 7 is a diagram for explaining a method of use when opening the container 190 to which the peeling detection label 101 is stuck as shown in FIG. 6 and the action at that time.

  When opening the container 190 to which the peeling detection label 101 is stuck as shown in FIG. 6B, the longitudinal ends of the film sheets 110 and 140 are peeled off as shown in FIG. It peels from the container 190 as a starting end. Then, since the film sheet 110 and the film sheet 140 are not attached to each other by the peeling base material 160 at both ends in the longitudinal direction, as shown in FIG. The film sheet 110 and the film sheet 140 are about to peel off in a state where the base material 160 is adhered to the film sheet 110 by the adhesive layer 120a.

  Moreover, since the adhesion force with respect to the container 190 of the adhesion layer 120b is stronger than the adhesion force with the film sheet 110 of the adhesion layer 120a, the film sheet 110 and the film sheet 110 remain adhered to the container 190. The film sheet 140 is peeled off. Then, since the adhesive force with the film sheet 140 of the adhesive layer 120a is stronger than the adhesive force with the film sheet 110, the adhesive layer 120a is applied to the film sheet 140 as shown in FIG. It peels from the film sheet 110 with the laminated state. Moreover, in the area | region where the peeling layer 130 of the film sheet 140 was laminated | stacked, as shown in FIG.7 (b), the adhesive layer 120a peeled from the film sheet 140 by the peeling layer 130, and was laminated | stacked on the film sheet 110 Will remain.

  In this way, when the peeling detection label 101 is peeled from the container 190 with the longitudinal ends of the film sheets 110 and 140 as peeling start ends, the film sheet 140 is received as shown in FIG. The film sheet 110 and the film sheet 140 are peeled off while being adhered to the container 190, and the adhesive layer 120a remains laminated on the film sheet 140 in the region where the peeling layer 130 of the film sheet 140 is not laminated. In the region where the release layer 130 is laminated, the adhesive layer 120a peels from the film sheet 140. In addition, since the film sheet 110 and the film sheet 140 are not attached to each other by the peeling base material 160 at both ends in the longitudinal direction, any end in the longitudinal direction of the film sheets 110 and 140 is obtained. Even when peeled from the part, the same effect occurs.

  Then, since the adhesive layer 120a is made of a colored adhesive, as shown in FIG. 7 (d), the opening information 102 having a pattern corresponding to the peeling layer 130 appears by the adhesive layer 120a. Since the film sheet 140 is divided into two regions by the slit 141 formed in the central portion in the longitudinal direction, when the peeling detection label 101 is stuck to the container 190 across the opening portion 193, the film sheet One of the two areas divided by the slit 141 of 140 is attached to the lid 191 of the container 190 and the other is attached to the main body 192, and the film sheet 140 is placed in the container 190. The container 190 can be opened while being attached to the container. Thus, when the peeling detection label 101 is to be peeled from the container 190 in order to open the container 190, the film sheet 110 and the film sheet 140 are peeled and the opening information 102 appears, whereby the container It can be detected that 190 has been opened illegally.

  Next, the peeling method from the container 190 of the peeling detection label 101 is demonstrated.

  FIG. 8 is a view for explaining a method of peeling the peeling detection label 101 from the container 190 after the container 190 is opened as shown in FIG.

  In the state where the container 190 is opened as shown in FIG. 7, the film sheet 140 is adhered to the container 190 by the adhesive layer 120 b, but the adhesive layer is not provided in the region along the slit 141 of the film sheet 140. 120b is not laminated, so that the region along the slit 141 of the film sheet 140 is not attached to the container 190. Therefore, as shown in FIG. 8A, the two regions of the film sheet 140 can be separated from the container 190 using the region where the adhesive layer 120b on the slit 141 side is not laminated as the separation start end. .

  Thereafter, by peeling the two regions of the film sheet 140 from the container 190, the peel detection label 1 can be completely peeled from the container 90 as shown in FIG.

  As described above, in this embodiment, after the film sheet 110 and the film sheet 140 are peeled off, peeling from the container 190 is detected, and then the film sheet 140 that is still attached to the container 190. The film sheet 140 is separated from the container 190 with the region along the slit 141 dividing the film sheet 140 into two regions as the separation start end. The peeling detection label 101 cannot be peeled from the container 190 using the region along the slit 141 of the sheet 140, and thus the container 190 after use can be detected while being illegally peeled from the container 190. Can be peeled cleanly.

  In this embodiment, the adhesive layer 120b is laminated on the entire surface of the film sheet 140 on the opposite side of the film sheet 110 to the release sheet 150. However, the release sheet 150 is attached to the film sheet 140. The adhesive layer 120b may be laminated only on a part including both ends of the film sheet 140 in the longitudinal direction, as long as it is sufficient for being peelably attached.

(Third embodiment)
FIG. 9 is a view showing a third embodiment of the peeling detection label of the present invention, where (a) is a front view, (b) is a cross-sectional view along AA ′ shown in (a), and (c). Is a back view.

  As shown in FIG. 9, the peeling detection label in this embodiment is the opposite side of the peeling sheet 250 from the sticking surface of the film sheet 240 to the film sheet 210 with respect to that shown in the first embodiment. A circular slit 253 is formed at the central portion in the longitudinal direction, and a slit 254 is formed inside the slit 253 so as to face the slit 241 of the film sheet 241. Is different. Thereby, in this form, the field surrounded by slit 253 of exfoliation sheet 250 serves as a non-adhesion part.

  Below, the usage method of the peeling detection label 201 comprised as mentioned above is demonstrated.

  First, a method for attaching the peeling detection label 201 shown in FIG. 9 to an adherend will be described.

  FIG. 10 is a diagram for explaining a method for attaching the peeling detection label 201 shown in FIG. 9 to an adherend.

  When sticking the peeling detection label 201 shown in FIG. 9 to the adherend, first, the peeling sheet 250 is peeled as shown in FIG. Since the release sheet 250 is detachably attached to the film sheet 240 by laminating the release layer 252 on the base substrate 251, for example, the release sheet 250 is peeled off from the film sheet 240 with the end portion being the start of peeling. can do.

  Then, the adhesive layer 220b laminated on the surface of the film sheet 240 opposite to the surface to be adhered to the film sheet 210 is exposed, and, as shown in FIG. Can be attached to the container 290. At this time, since the release sheet 250 has a circular slit 253 formed in the central portion in the longitudinal direction, the inner region of the slit 253 is separated from the release sheet 250 and remains attached to the film sheet 240. It has become.

  As shown in FIG. 10C, the container 290 in this embodiment is composed of a lid portion 291 and a main body portion 292, and has a structure that can be opened by lifting the lid portion 291. The peeling detection label 201 is pasted across the unsealed part 293 that is a boundary part with the part 292.

  Next, as shown in FIG. 10, a method of use when opening the container 290 to which the peeling detection label 201 is attached and the action at that time will be described.

  FIG. 11 is a diagram for explaining a method of use when opening the container 290 to which the peeling detection label 201 is attached as shown in FIG. 10 and the operation at that time.

  When opening the container 290 to which the peeling detection label 201 is attached as shown in FIG. 10B, the longitudinal ends of the film sheets 210 and 240 are peeled off as shown in FIG. It peels from the container 290 as a starting end. Then, since the film sheet 210 and the film sheet 240 are not attached to each other by the peeling base material 260 at both ends in the longitudinal direction, the peeling as shown in FIG. The film sheet 210 and the film sheet 240 are about to peel off in a state where the base material 260 is adhered to the film sheet 210 by the adhesive layer 220a.

  Moreover, since the adhesion force with respect to the container 290 of the adhesion layer 220b is stronger than the adhesion force with the film sheet 210 of the adhesion layer 220a, the film sheet 210 and the film sheet 210 remain adhered to the container 290. The film sheet 240 peels off. Then, since the adhesive force with the film sheet 240 of the adhesive layer 220a is stronger than the adhesive force with the film sheet 210, the adhesive layer 220a is applied to the film sheet 240 as shown in FIG. It peels from the film sheet 210 with the laminated state. Moreover, in the area | region where the peeling layer 230 of the film sheet 240 was laminated | stacked, as shown in FIG.11 (b), the adhesive layer 220a peeled from the film sheet 240 by the peeling layer 230, and was laminated | stacked on the film sheet 210 Will remain.

  In this way, when the peeling detection label 201 is peeled from the container 290 with the longitudinal ends of the film sheets 210 and 240 as peeling start ends, the film sheet 240 is housed as shown in FIG. The film sheet 210 and the film sheet 240 are peeled off while being adhered to the container 290, and the adhesive layer 220a remains laminated on the film sheet 240 in a region where the peeling layer 230 of the film sheet 240 is not laminated. In the region where the release layer 230 is laminated, the adhesive layer 220a peels from the film sheet 240. In addition, since the film sheet 210 and the film sheet 240 are not attached to each other by the peeling base material 260 at both ends in the longitudinal direction, either end of the film sheets 210 and 240 in the longitudinal direction. Even when peeled from the part, the same effect occurs.

  Then, since the adhesive layer 220a is made of a colored adhesive, as shown in FIG. 11D, the opening information 202 having a pattern corresponding to the peeling layer 230 appears by the adhesive layer 220a. Since the film sheet 240 is divided into two regions by the slit 241 formed in the central portion in the longitudinal direction, the film is obtained when the peeling detection label 201 is stuck to the container 290 across the opening portion 293. One of the two regions divided by the slit 241 of the sheet 240 is attached to the lid 291 of the container 290 and the other is attached to the main body 292. The film sheet 240 is the container. The container 290 can be opened while being attached to the 290. Thus, when it is going to peel the peeling detection label 201 from the container 290 in order to open the container 290, the film sheet 210 and the film sheet 240 peel and the opening information 202 appears, so that the container It can be detected that 290 has been opened illegally.

  Next, the peeling method from the container 290 of the peeling detection label 201 is demonstrated.

  FIG. 12 is a view for explaining a method of peeling the peeling detection label 201 from the container 290 after the container 290 is opened as shown in FIG.

  In the state where the container 290 is opened as shown in FIG. 11, the film sheet 240 is adhered to the container 290 with the adhesive layer 220 b, but the region and slits of the film sheet 240 in which the slit 241 is formed A region surrounded by the slit 253 of the release sheet 250 is attached to a part of the region along the line 241, and thereby, one of the region along the slit 241 and the region where the slit 241 is formed on the film sheet 240. The part is not attached to the container 290. Therefore, as shown in FIG. 12A, the two regions of the film sheet 240 can be peeled from the container 290 with the region surrounded by the slits 253 of the release sheet 250 as the peeling start end.

  Thereafter, by peeling the two regions of the film sheet 240 from the container 290, the peel detection label 201 can be completely peeled from the container 290 as shown in FIG.

  As described above, in this embodiment, after the film sheet 210 and the film sheet 240 are peeled off and peeling from the container 290 is detected, the film sheet 240 that is still attached to the container 290. From the container 290, a part of the release sheet 250 that remains attached to the area where the slit 241 is formed to divide the film sheet 240 into two areas and the area along the slit 241 is used as a peeling start end. Since it will peel, unless it is after the film sheet 210 and the film sheet 240 peel, the peeling detection label 201 may be peeled from the container 290 using the area | region enclosed by the slit 253 of the peeling sheet 250. It cannot be accommodated after use while it can detect that it has been illegally detached from the container 290 It can be cleanly separated from the 290. Furthermore, this form forms the circular slit 253 in the longitudinal direction center part of the peeling sheet 250, and the area | region enclosed by the slit 253 is the film sheet 240 in the state in which the peeling detection label 201 was affixed on the container 290. By constructing the non-adhesion part by remaining adhered to the film, the non-adhesion part can be realized only by devising the structure of the release sheet 250.

  In this embodiment, the adhesive layer 220b is laminated on the entire surface of the film sheet 240 opposite to the film sheet 110. However, in the region inside the slit 253, the region inside the slit 253 of the release sheet 250 is formed. Although the adhesive layer 220b needs to be laminated in order to adhere to the film sheet 240, the release sheet 250 is attached to the film sheet 240 in a peelable manner outside the slit 253 of the release sheet 250. The adhesive layer 220b may be laminated on only a part of the film sheet 240 including both ends in the longitudinal direction, as long as it is sufficient.

  Moreover, in embodiment mentioned above, film sheet 10,110,210 and film sheet 40,140,240 are laminated | stacked by laminating the peeling layers 30,130,230 to a part of film sheet 40,140,240. Is peeled off from the film sheets 40, 140, 240, but the printing to remove the adhesive force of the adhesive layers 20a, 120a, 220a is performed on the release layer 30, Instead of 130 and 230, the film sheet 40, 140 and 240 may be provided.
