Description

  The present invention relates to a label, and more particularly, to a label that can be peeled off after being applied and that can be used for various purposes including sealing for identifying that it has been tampered with.

  The conventional general label uses the surface of the substrate as the printing surface, and an adhesive is provided on the back of the substrate, and is applied to the desired location with this adhesive. The label is peeled off depending on the adhesive strength of the adhesive. There are some that are difficult and others that can be peeled off, and various configurations are known.

  In addition, as a sealing label that can be identified as having been tampered with, the label was broken when it was tampered with, and it was unsuccessfully opened due to the fact that the initial stuck state could not be restored and traces remained on the pasting surface. There is known a configuration that makes it possible to identify the. For example, when the label base material is divided into two equal parts by dividing perforations, an adhesive layer for application is provided on the back side, and each divided portion is peeled from each end in the direction of the dividing perforations. While breaking the label base material, forming the cutting line for preventing tampering that breaks the split perforation and prevents the label base material from being broken when peeled off in the end direction. Thus, there is a sealing label that is used by attaching the dividing perforation corresponding to the boundary between the main body of the container and the lid (Patent Document 1).

  In addition, for example, the label base material is divided into two equal parts by dividing perforations, an adhesive layer for sticking is provided on the back surface, a tamper-proof cut is formed at each end, If it is peeled off in the direction of the perforation for splitting, the label substrate will be torn from the cut portion for preventing unauthorized opening, while if the perforation for splitting is broken and peeled off in the direction of the edge from this, the tampered opening will occur. There is a sealing label that is used by preventing the cut portion for prevention from being broken and applying the dividing perforation in correspondence with the boundary between the container body and the lid (Patent Document 2).

  However, the conventional general label described above has a disadvantage that it cannot be applied to various uses because it has only a usage method of sticking difficult to peel or sticking so as to be peelable.

  Further, the sealing labels using the above-described conventional labels all identify the presence or absence of unauthorized opening by the cutting line for preventing unauthorized opening or the cutting state of the cutting part. Is provided corresponding to the pressure-sensitive adhesive layer, and as a result of deterioration of the pressure-sensitive adhesive forming the pressure-sensitive adhesive layer, it peels off from the cutting line and the cut portion and cannot function to prevent unauthorized opening. There is an inconvenience. Furthermore, these conventional sealing labels may have the disadvantage that the cutting line and the cut portion may be cut due to careless handling, and in this case as well, the function of preventing unauthorized opening cannot be achieved. .

  An object of the present invention is to solve the above-mentioned inconveniences and to provide a label that can be used for various purposes including a sealing label.

  In order to achieve this object, a label according to claim 1 of the present invention has a strong adhesive layer and a weak adhesive layer that are peelable after being applied to each other on one side of a label substrate in parallel. And a perforation for splitting is provided on the weak adhesive layer side along the boundary of each adhesive layer of the label base material.

  According to the label according to claim 1, since the adhesive strength of the strong adhesive layer and the weak adhesive layer is different, when peeled from the weak adhesive layer side in the pasting state, at the boundary to the strong adhesive layer side Since the adhesive force is relatively increased and the resistance to peeling is abruptly increased, a force is applied to the dividing perforation, and this is broken. On the other hand, when peeling from the strong pressure-sensitive adhesive layer side, the adhesive strength is relatively weak at the boundary to the weak pressure-sensitive adhesive layer side. And can be peeled together. This breaking perforation breaks the adhesive strength of the weak adhesive layer and the strong adhesive layer, the adhesive strength of the weak adhesive layer is smaller than the breaking strength of the split perforation, the strong adhesive layer If the adhesive strength is set to be greater than the breaking strength of the dividing perforation, it is easily achieved.

  Similarly, in order to achieve the above-mentioned object, the label according to claim 2 of the present invention is the peeling start portion of the label according to the structure of claim 1 at the end of the strong adhesive layer on the side opposite to the perforation lines. Are connected to each other via As said peeling start part, each adhesion for inserting perforation for forming the peeling start end of Claim 3, and an appropriate opening tool, such as a fingertip of Claim 4, to start peeling The non-adhesion part provided in the agent layer installation surface side is employable.

  According to the labels according to claims 2 to 4, since the adhesive force between the strong adhesive layer and the weak adhesive layer is different, in the pasting state, when peeling from the weak adhesive layer side corresponding to each end side, Since the adhesive force is relatively increased at the boundary to the strong adhesive layer side and the resistance to peeling is abruptly increased, a force is applied to the perforating perforation to break it. On the other hand, if the perforation that is the peeling start part is broken to form the peeling start end, or the fingertip is inserted into the non-adhesive part that is the peeling start part, and the peeling is performed from the strong adhesive layer side of the connecting part, Can be peeled off. And the relationship between the breaking strength of the perforation for facilitating the breaking of the dividing perforation and the adhesive strengths of the weak pressure-sensitive adhesive layer and the strong pressure-sensitive adhesive layer is the same as described above.

  According to the label according to claim 1 of the present invention, since two peeled states can be realized in the pasting state, there is an effect that it can be applied to various purposes according to the state of the peeled label.

  According to the labels of claims 2 to 4 of the present invention, it is particularly suitable to be applied to a sealing label, and whether or not tampering has been opened is visually easily identified by the presence or absence of breaking perforations. Even if the perforation for cutting is not broken, if the perforation of the connection part is broken or if the vicinity of the connection part is lifted off from the sticking surface as if it was peeled off, the tampering It can be easily identified visually, and after opening, the label substrate affixed to the container can be removed cleanly from the connecting part side, thus impairing the aesthetics when reusing the affixed container There is no effect.

  Hereinafter, a preferred embodiment of the label of the present invention will be described with reference to FIGS. As shown in FIGS. 1 to 3, the label 1 is a single piece, and is divided into a label base 2 made of a synthetic resin film, paper, or the like, and is divided into two large and small divided portions 2 a and 2 b. 3 is provided. A strong pressure-sensitive adhesive layer 4 and a weak pressure-sensitive adhesive layer 5 that can be peeled off after being attached are provided in parallel on the back surface side of the label substrate 2, and the strong pressure-sensitive adhesive layer 4 and the weak pressure-sensitive adhesive layer 5 are made of release paper. 6 is covered.

  As shown in FIGS. 2 and 3, the dividing perforation 3 is provided on the weak adhesive layer 5 side along the boundary between the adhesive layers 4 and 5. And the adhesive force of the said weak adhesive layer 5 and the said strong adhesive layer 4 is relatively different, and although it is not limited to a specific adhesive force mutually, once it sticks, it peels from a sticking surface in normal handling Without setting, it is set so that it can be peeled off when a predetermined force or more is applied. Further, when the adhesive strength of the weak adhesive layer 5 is set smaller than the breaking strength of the dividing perforation 3, and the adhesive strength of the strong adhesive layer 4 is set larger than the breaking strength of the dividing perforation 3, When the peeling from the weak pressure-sensitive adhesive layer 5 side, the cutting perforation 3 is reliably broken, while when the peeling from the strong pressure-sensitive adhesive layer 4 side, the cutting perforation 3 Are preferably peeled together without breaking.

  Then, the usage method of the label 1 mentioned above is demonstrated. The label 1 is peeled off the release paper 6 on the back side, and is stuck on the desired sticking surface P by the exposed adhesive layers 4 and 5. When the label 1 is peeled from the weak pressure-sensitive adhesive layer 5 side as shown in FIG. 4, the adhesive force is relatively increased at the boundary to the strong pressure-sensitive adhesive layer 4 side, and the resistance to peeling suddenly increases. A force is applied to the dividing perforation 3 to break it. Therefore, only the parting part 2b is peeled, and the parting part 2a is in a peeled state remaining on the pasting surface. In the label 1 using this first peeled state, the dividing portion 2b can be applied to a receipt slip or a delivery absence slip.

  On the other hand, as shown in FIG. 5, when the label 1 is peeled from the strong pressure-sensitive adhesive layer 4 side, the adhesive strength is relatively weak at the boundary to the weak pressure-sensitive adhesive layer 5 side. Since no force is applied to the perforation 3, this is not broken. Therefore, the label 1 is in a peeled state that can be peeled integrally. The label 1 using the second peeled state can be divided into the divided portions 2a and 2b as necessary after peeling, and the divided portions 2a and 2b can be used as independent labels.

  Next, an embodiment in which the present invention is applied to a sealing label will be described with reference to FIGS. The sealing label of the present embodiment is a pair of the above-described labels 1 on the side opposite to the perforating lines 3, that is, on the side of the strong adhesive layer 5, that is, a split perforation serving as a peeling start portion. It is connected through.

  As shown in FIGS. 6 and 7, the sealing label 11 is a single piece, and is divided into two divided portions 2a and 2b into a label base material 12 made of a synthetic resin film or paper. A perforation 17 is provided. The dividing perforations 17 are positioned so as to correspond to the boundary X between the main body 18a and the lid 18b when the label base 12 is attached to the container 18 shown in FIG. Further, on the side of the label substrate 12 opposite to the dividing perforations 17, dividing perforations 13 are provided.

  As shown in FIG. 7, the strong adhesive layer 14 and the weak adhesive layer 5 that can be peeled off after being attached are disposed on the back surface of the label substrate 12, and the weak adhesive layer 15 is located on both sides of the strong adhesive layer 14. The strong pressure-sensitive adhesive layer 14 and the weak pressure-sensitive adhesive layer 15 are covered with a release paper 16. Each dividing perforation 13 is provided on each weak adhesive layer 15 side along the boundary between the adhesive layers 14 and 15.

  And the adhesive force of the weak adhesive layer 15 and the strong adhesive layer 14 is relatively different, and is not limited to a specific adhesive force, but once attached to the container 18 shown in FIG. Then, it does not peel off from the container 18 but is set so that it can be peeled off when a predetermined force or more is applied. Further, when the adhesive strength of the weak adhesive layer 15 is set smaller than the breaking strength of the dividing perforation 13, and the adhesive strength of the strong adhesive layer 14 is set larger than the breaking strength of the dividing perforation 13, When the peeling from the weak pressure-sensitive adhesive layer 15 side, the dividing perforation 13 is reliably broken, while when the peeling from the strong pressure-sensitive adhesive layer 14 side, the dividing perforation 13 Are preferably peeled together without breaking.

  Then, the usage method of the label 11 for sealing mentioned above is demonstrated. The sealing label 11 is peeled off the release paper 16 on the back side, and pasted by the exposed adhesive layers 14 and 15 so as to straddle the main body 18a and the lid 18b of the container 18 as shown in FIG. be able to. At this time, the dividing perforation 17 is positioned so as to correspond to the boundary X between the main body 18a of the container 18 and the lid 18b.

  In the state of FIG. 8, if the dividing perforation 17 is broken, it is visually identified that an unauthorized opening has been attempted. Further, when an attempt is made to open the lid 18b of the container 18 without breaking the dividing perforations 17, the end of the label base 12 opposite to the dividing perforations 17 is turned up. It will be. Then, since the adhesive force is relatively increased at the boundary where the peeled portion of the label substrate 12 moves from the weak pressure-sensitive adhesive layer 15 to the strong pressure-sensitive adhesive layer 14 side, and the resistance to peeling suddenly increases, the dividing perforation 13 As shown in FIG. 9, the dividing perforation 13 is broken. Since the broken state cannot be repaired, it is possible to easily visually identify that the label substrate 12 has been tampered with by breaking the label substrate 12.

  On the other hand, in the case of normal opening, in the state shown in FIG. 8, first, the dividing perforation 17 of the label substrate 12 is broken. This dividing perforation 17 corresponds to the boundary X between the main body 18a and the lid 18b. Therefore, the breaking operation can be easily performed by applying a force along the border X with a fingernail or the like. Next, when the label base 12 is turned up with this broken end as a peel start end, the label base 12 is sequentially peeled from the container 18 as shown in FIG. Even if the peeled portion reaches the boundary where the strong pressure-sensitive adhesive layer 14 moves to the weak pressure-sensitive adhesive layer 15, in this case, the force that resists peeling suddenly weakens, so that the dividing perforation 13 is not broken. It will be peeled off smoothly. In this way, each of the divided portions 12a and 12b is cleanly separated from the container 18.

  In this regular opening operation, the label substrate 12 can be cleanly peeled from the container 18 for each of the divided portions 12a and 12b. Therefore, when the container 18 is reused, the sealing label 11 is removed. It can be used without leaving a trace of the sticking and without damaging the aesthetics.

  FIG. 11 shows a cross section at the same position as FIG. 7 in another embodiment relating to the sealing label of the present invention. The sealing label 21 of the present embodiment is different from the sealing label 11 described above in that the separation start perforation 17 is replaced with a non-adhesive part, more specifically, an adhesion inhibitor layer 27. It is only the structure which provided.

  That is, as shown in FIGS. 11 and 12, the sealing label 21 is a single piece and is provided with a dividing perforation 23 on both ends of the label base material 22 made of a synthetic resin film or paper. ing. On the back surface of the label substrate 22, a strong pressure-sensitive adhesive layer 24 and a weak pressure-sensitive adhesive layer 25 that can be peeled off after being attached are provided in parallel so that the weak pressure-sensitive adhesive layer 25 is located on both sides of the strong pressure-sensitive adhesive layer 24. A central portion of the strong pressure-sensitive adhesive layer 24 is provided with an adhesion inhibitor layer 27 extending in parallel with the dividing perforation 23 over a predetermined width, and a release paper 26 is provided over the entire surface. Each of the perforations 23 for cutting is provided on the side of each of the weak pressure-sensitive adhesive layers 25 along the boundary between the pressure-sensitive adhesive layers 24 and 25.

  And the adhesive force of the weak adhesive layer 25 and the strong adhesive layer 24 is relatively different, and is not limited to a specific adhesive force, but once pasted on the container 28 (see FIGS. 13 and 8). In normal handling, it does not peel off from the container 28 but is set to be peelable when a predetermined force or more is applied. Moreover, the adhesion inhibitor layer 27 is formed by applying an adhesion inhibitor, for example, by applying a release agent or various printing inks.

  Then, the usage method of the label 21 for sealing mentioned above is demonstrated. The sealing label 21 is peeled off the release paper 26 on the back side, and pasted by the exposed adhesive layers 24 and 25 so as to straddle the main body 28a and the lid 28b of the container 28 as shown in FIG. be able to. At this time, the adhesion inhibitor layer 27 is positioned so as to correspond to the boundary Y between the main body 28a of the container 28 and the lid 28b.

  When the end of the label base material 22 is turned up in an attempt to open the lid 28b of the container 28 in an unauthorized manner, the peeled portion of the label base material 22 moves relative to the boundary where the weak adhesive layer 25 moves to the strong adhesive layer 24 side. Since the adhesive force is increased and the resistance to peeling is abruptly increased, a force is applied to the dividing perforation 23, and this is broken (see FIG. 9). Since the broken state cannot be repaired, it is possible to easily visually identify that the tampering has been opened based on the breakage of the dividing perforation 23 of the label base material 22 or the trace of the breakage.

  On the other hand, when opening normally, as shown in FIG. 13, an opening tool, for example, a fingertip F of an opener is inserted between the adhesion inhibitor layer 27 of the sealing label 21 and the container 28, and the label base material is inserted. When peeling 22 toward the end from the center, even if the peeled portion reaches the boundary where the strong adhesive layer 24 moves to the weak adhesive layer 25, the force that resists peeling suddenly weakens, and the cutting sewing machine The eyes 23 are peeled cleanly without being broken, keeping the integrated state. Therefore, when the container 28 is reused, there is no trace of the sealing label 21 attached, and the container 28 can be used without impairing the aesthetics. In addition, when an unauthorized opening is attempted by this regular opening method, the portion corresponding to the adhesion inhibitor layer 27 into which the opening tool has been inserted is in a raised state and cannot be restored to the initial state. Can be easily identified.

  FIG. 14 shows still another embodiment relating to the sealing label of the present invention, and shows a cross section at the same position as FIG. The sealing label 31 of the present embodiment is different from the sealing label 21 described above only in the configuration of the non-adhesive part as the peeling start part. That is, by not providing the strong pressure-sensitive adhesive layer 34 at the central portion of the one surface of the label base material 32 (the portion where the adhesion inhibitor layer 27 in FIG. 11 is provided), the pressure-sensitive adhesive is not applied as the exposed surface of the base material sheet 32. The part 37 is formed, and the non-adhesive part is constituted by the adhesive non-applied part 37. And the other structure of the label 31 for sealing is the same as the label 21 for sealing, In FIG. 14, 33 is a perforation for a parting, 35 is a weak adhesive layer, 36 is a release paper.

  Also in this embodiment, when the sealing label 31 affixed to the container is tampered with, the dividing perforation 33 breaks, while an opening tool is inserted between the adhesive non-applying portion 37 and the container, According to the regular opening method in which the material 32 is peeled from the center portion toward the end portion, the dividing perforation 33 is peeled cleanly in an integrated state without being broken. In addition, when an unauthorized opening is attempted by this regular opening method, the portion corresponding to the adhesive non-applied portion 37 into which the opening tool has been inserted is in a raised state and cannot be restored to the initial state. It can be easily identified visually. Therefore, also in the present embodiment, it is possible to visually identify that the tampering has been opened, and when the container is reused, there is no trace of the sealing label 31 attached, and the aesthetic sense is not left. It can be used without damaging it.

  The present invention is not limited to the above-described embodiment. For example, the sealing labels 1, 11, 21, and 31 are not in a single piece state, but in a continuous state in which they are connected via a cutting perforation. In addition, in this case, the pressure-sensitive adhesive layers 4, 5, 14, 15, 24, 25, 34 of the label base materials 2, 12, 22, 32, By providing the release agent layer on the side opposite to the surface 35, the release papers 6, 16, 26, and 36 become unnecessary. Moreover, if the strong adhesive layer 14 corresponding to the dividing perforations 17 is not provided, the dividing perforations 17 can be easily broken in a state where they are attached to the containers 18 and 28.
