Description

  The present invention relates to an unsealing detection label for detecting the fact that a tampering is unsuccessfully performed after being stuck on an adherend and sealed.

  2. Description of the Related Art Conventionally, home delivery services have been performed in which home delivery companies deliver foods and the like to users' homes. In this service, when the user is absent, the driver of the courier places a cold box containing ingredients at a designated place such as the entrance, and a seal is pasted on the boundary between the container and the lid. This prevents a third party from opening the cold box without permission to steal the contents or perform mischief when the user is absent.

  As a seal used for such applications, for example, an anti-opening seal disclosed in Patent Document 1 is known. This anti-opening seal has a two-sheet structure in which paper is crimped to the surface of a semi-transparent thin seal. If you try to force the container lid open after applying the seal, the paper on the surface will be torn. Opening can be detected.

Utility Model Registration No. 3075738

  By the way, in the conventional anti-opening seal as described above, the first sheet is larger than the second seal so that it can be picked up with a finger when peeled off. For this reason, when the seal is affixed to the container, the periphery of the first sheet is lifted from the container, and if this part is caught by another object, the seal may be peeled off. Further, in order to prevent such peeling off, for example, when the first sheet and the second sheet have the same size, the sheet and the sheet can be simultaneously removed. For this reason, both of them can be peeled off at the same time and then pasted again, making it impossible to know that they have been tampered with.

  The present invention has been made in view of such circumstances, and the problem to be solved is that it can be prevented from falling off after being stuck on an adherend and sealed, and it has been ensured that it has been tampered with. Another object of the present invention is to provide an opening detection label that can be detected.

  In order to solve the above-described problems, an unsealing detection label according to the present invention includes a label base material, a peel seal that is slightly larger than the label base material and attached to the surface of the label base material via a pseudo adhesive layer, and a label base material. A release paper affixed to the back side of the adhesive layer via an adhesive layer, and a label base material having an adhesive part having adhesiveness in the longitudinal center, and a non-adhesive part having no adhesiveness at both longitudinal ends. A cut line for dividing the label base material is provided at the boundary between the adhesive portion and the non-adhesive portion. According to such a structure, if the release paper is peeled off, it can be attached to the adherend by the adhesive part, and when the release seal is peeled off, the label base material is divided into an adhesive part and a non-adhesive part via a tear line, Functions as an opening detection unit.

  Further, in the unsealing detection label according to the present invention, when the tear line is composed of a cut part that cuts the label base material and an uncut part that does not cut the label base material, the adhesive part when peeling the release paper And the non-adhesive portion are preferable because they can be held together so as not to be inadvertently divided.

  Further, in the unsealing detection label according to the present invention, when an adhesive part having adhesiveness is provided on a part of the non-adhesive part, lifting of the end of the label base material is eliminated when the label is attached to an adherend. Is preferable.

  According to the unsealing detection label according to the present invention, since the label base material affixed to the adherend is almost the same size as the peel seal, the peel seal does not float from the adherend and is difficult to peel off. Further, it is possible to prevent dropping after being stuck and sealed on the adherend. Further, according to the opening detection label according to the present invention, if the peeling seal is peeled off, the label base material is divided into the adhesive part and the non-adhesive part through the cut line and cannot be restored to the original state. The detected facts can be detected with certainty.

It is the external view of the opening detection label which concerns on this invention, and the one part is fractured | ruptured and shown. It is the sectional view on the AA line of FIG. It is the enlarged plan view which looked at the opening detection label from the back surface side of the label base material. It is explanatory drawing which showed the state when the opening detection label was stuck on the cold box, (a) is the external view, (b) is the sectional drawing. It is explanatory drawing which showed the state when a peeling seal was peeled off from the unseal | open detection label affixed on the cool box, (a) is the external view, (b) is the sectional drawing. It is explanatory drawing which showed the state when peeling the label base material left in the cool box, (a) is the external view, (b) is the sectional drawing.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 shows an example in which an opening detection label according to the present invention is applied to a seal seal used in a home delivery service. This sticker can be used by a third party other than the user without permission when the driver of the delivery company delivers the food to the user's home and is pasted on a cold box containing the food in the absence. It is for sealing so as not to open. In this embodiment, in consideration of work efficiency during use by a driver, a plurality of unsealing detection labels 1, 1,... Formed in a strip shape are provided adjacent to each other on a continuous sheet of a predetermined size. Each opening detection label 1 has a three-sheet structure composed of a label substrate 2, a peel seal 3, and a release paper 4. The configuration of each part will be described in detail below.

  The label base material 2 is a part that functions as a display unit that indicates that a part of the label base material 2 remains attached to the adherend when it is opened and is opened by information printed on the surface thereof. The material of the label base material 2 is not particularly limited as long as it can be printed. For example, various papers such as high-quality paper, art paper, and coated paper, and various resin films such as polyester film and polypropylene film may be used. it can. As the information for displaying the opening on the surface of the label base material 2, the characters “opened” are printed here, but the information to be printed may be other characters, or is not limited to characters, It may be a symbol.

  As shown in FIG. 2, an adhesive layer 5 is provided on the back surface of the label substrate 2. The adhesive layer 5 is formed by uniformly applying various adhesives such as rubber-based, acrylic-based, hot-melt-based, and silicone-based to the back surface of the label substrate 2, and among them, acrylic used especially for paper tack A system emulsion type pressure-sensitive adhesive is preferred. However, it is preferable that the adhesive is peeled off after the label substrate 2 is attached to the adherend.

  As shown in FIG. 3, when the unsealing detection label 1 is viewed from the back side of the label base material 2, there are two types: an adhesive part 6 provided at the center in the longitudinal direction and a non-adhesive part 7 provided at both ends in the longitudinal direction. A partition is formed in this area.

  The adhesive part 6 is an adhesive part for sticking the label base material 2 to the adherend, and the non-adhesive part 7 is an adhesive part to make the label base material 2 easy to peel off from the release paper 4 or the adherend. It is a part which does not have. Among these, the non-adhesive part 7 is a paste-killing process that seals the adhesive force of the adhesive layer 5, and after applying varnish or printing ink to the surface of the release paper 4, the non-adhesive part 7 is bonded to the label base 2. Varnish or printing ink is transferred onto the adhesive layer 5 to coat the adhesive surface. Although not shown in the figure, the configuration of the non-adhesive portion 7 includes a configuration in which a non-application portion where no adhesive is applied is provided on the label substrate 2 in addition to the coating of the adhesive layer 5, and a release agent is applied to the label substrate 2. A structure in which a release layer is provided can also be employed. A part of the non-adhesive part 7 is left in a state where the adhesive part 6 is exposed in the form of a paste without covering the adhesive layer 5, but this is a label base material when it is affixed to an adherend. This is to eliminate the lifting of the end of 2.

  A cut line 8 that divides the label base material 2 is provided at a boundary portion between the adhesive portion 6 and the non-adhesive portion 7. In this embodiment, the cut line 8 includes a cut portion 8a cut so as to penetrate the label base material 2, and an uncut portion 8b that does not cut the label base material 2 arranged in the middle of the cut portion 8a. Yes. The tear line 8 functions as an opening detection unit that informs that the label has been opened by dividing the label substrate 2 into an adhesive portion 6 and a non-adhesive portion 7 when peeled off from the adherend. The reason why the uncut portion 8b is arranged in the middle of the cut portion 8a is to keep the adhesive portion 6 and the non-adhesive portion 7 from being inadvertently divided when the release paper 4 is peeled off.

  A peel seal 3 is affixed to the surface of the label substrate 2. The peel seal 3 is a portion that is peeled off from the label base material 2 when the unsealing detection label 1 is peeled off from the adherend. In this embodiment, the peel base 3 is prohibited from being attached again after being peeled off. Is pseudo-bonded to. The material of the peeling seal 3 is not particularly limited as long as it can be printed, and the same material as that of the label substrate 2 can be used. However, the peel seal 3 has a width and a length that are slightly larger than the label base 2 so that the entire label base 2 is completely hidden.

  Further, as a configuration in which the peel seal 3 is pseudo-bonded, the peel seal 3 is attached to the surface of the label substrate 2 via the pseudo-adhesive layer 9. The pseudo-adhesion layer 9 can be formed by applying a pseudo-adhesive made of, for example, a natural rubber-based or synthetic rubber-based pressure sensitive adhesive. The pseudo-adhesive layer 9 may be any layer that cannot be re-applied after being peeled off. The pseudo-adhesive layer 9 is constituted by a so-called open type film in which transparent resin films are thermocompression bonded in place of the above-described configuration in which the pseudo-adhesive is applied. May be.

  A release paper 4 is attached to the back surface of the label substrate 2. The release paper 4 is a part that functions as a mount for holding the label substrate 2 and the release seal 3 until use. The release paper 4 is subjected to a release treatment in which a silicone release agent is applied to the entire surface thereof, and is peelably attached to the back surface of the label base 2 to protect the adhesive surface during storage and to label the substrate during use. The material 2 is peeled off. Note that the release paper 4 is larger in size than the release seal 2 in consideration of ease of peeling during use.

  The above is the configuration of the unsealing detection label 1 according to the present invention.

  First, as shown in FIG. 4, when the driver of the delivery company delivers the food to the user's home, if the user is not present, the food is put into the container 11 of the cold box 10 and the boundary between the container 11 and the lid 12 is placed. The opening detection label 1 is affixed to and sealed. At this time, the release paper 4 on the back side of the label is peeled off and pasted, but the non-adhesive portion 7 having no adhesiveness is provided at both ends in the longitudinal direction of the label base material 2 so as to become a hook at the time of peeling. Therefore, the release paper 4 can be easily peeled off from above and below the label. Further, since the cut line 8 of the label base material 2 is provided with an uncut portion 8b that holds the adhesive portion 6 and the non-adhesive portion 7 together, the adhesive portion 6 and the non-adhesive portion when the release paper 4 is peeled off. 7 is not inadvertently divided. Therefore, when the driver attaches the unsealing detection label 1, the driver can work while wearing gloves and the handling is convenient.

  The opening detection label 1 attached to the cold box 10 has a double structure of the peel seal 3 and the label base material 2 when viewed from the outside because the label base material 2 is completely hidden by the peel seal 3. It is difficult to notice that Further, since the label base 2 is approximately the same size as the peel seal 3, the peel seal 3 does not float from the cold box 10 and the both ends of the label base 2 are left in the form of a paste. Is glued by. In this way, since the attached unsealing detection label 1 is difficult to peel off, the unsealing detection label 1 can be prevented from falling off from the cold insulation box 10.

  By the way, if the label base material 2 and the peeling seal 3 are peeled off simultaneously from the unsealing detection label 1 attached to the cold box 10, it is not preferable because it can be pasted again even after the cold box 10 is opened. In that respect, in this embodiment, as shown in FIG. 5, the peeling seal 3 and the label base material 2 are substantially the same size, and when peeling, both are picked with a finger. Moreover, since the non-adhesive portion 7 is provided at both ends of the label base material 2 and the non-adhesive portion 7 does not have adhesiveness, the label base material 2 is adhered to the peeling seal 3 by the pseudo adhesive layer 9. It is peeled off.

  On the other hand, the adhesive part 6 is provided in the center of the label base material 2, and since the adhesive force of this adhesive part 6 is stronger than the adhesive force of the pseudo adhesive layer 9, only the peel seal 3 is peeled off. At this time, the uncut portion 8b of the cut line 8 at the boundary between the adhesive portion 6 and the non-adhesive portion 7 is cut, and the label substrate 2 is divided into the adhesive portion 6 and the non-adhesive portion 7. Therefore, when the user opens the cold insulation box 10 and takes out the contents, as shown in FIG. 5, when there is no peeling seal 3 in the cold insulation box 10 and the characters “opened” on the label base material 2 are visible. Is known to have been opened by someone illegally.

  As described above, when the unsealing detection label 1 attached to the cold box 10 is peeled off, the label base material 2 is divided into the adhesive portion 6 and the non-adhesive portion 7. And once the label base material 2 divided | segmented cannot be joined, the pseudo-adhesion layer 9 of the back surface of the peeling seal | sticker 3 peeled off does not have adhesive force. For this reason, after the peeling seal 3 is peeled off, it cannot be reapplied to the label base material 2 by the pseudo adhesive layer 9, so it is impossible to return the unsealing detection label 1 to the original state in the cold box 10. . Therefore, according to the unsealing detection label 1 of the present embodiment, it is possible to prevent a malicious act of peeling off the peeling seal 3 from the cold insulation box 10 and then reattaching it.

  In addition, the cold box 10 which has been used is collected by a delivery company. At this time, as shown in FIG. 6, the adhesive portion 6 of the label base material 2 is detachably attached via the adhesive layer 5, and corner cuts that become the starting point at the time of peeling are formed at the four corners of the adhesive portion 6. It is formed. Thereby, the label base material 2 can be easily peeled off from the upper and lower sides, and no adhesive residue is generated on the surface of the cold insulation box 10 after peeling. Therefore, the delivery agent can reuse the cold box 10 after removing the label base material 2.

  In the above embodiment, an example in which the opening detection label 1 is applied to a seal seal used in a home delivery service has been described. However, the application of the present invention is not limited to this, and the re-opening after the opening detection label 1 is peeled off. It can be similarly applied as long as it is for the purpose of preventing sticking.
