Description

  The present invention relates to a sealing seal used for restraining a sealed bag or box from being opened by a third party without permission, or for leaving a trace when the bag or box has been opened.

Conventionally, a sealing seal is provided with a pressure-sensitive adhesive layer on the back surface of a sheet-like base material, and has been crafted to leave an opening trace between the base material and the pressure-sensitive adhesive layer. Things are common. 7A and 7B show a typical sealing seal 1 of the related art. This sealing sheet 1 has a release layer 3 on a back surface of a sheet-like substrate 2 in a pattern (for example, “ It has a structure in which a pressure-sensitive adhesive layer 5 is provided on a transfer layer (aluminum vapor deposition layer or the like) 4 thereon, and a release sheet 6 is temporarily bonded thereon. The sealing seal 1 can be peeled off the release sheet 6 and attached to the sealing object 8 as shown in FIG. 8A. When the sealing seal 1 is attached to the sealing object 8, the sealing seal 1 is When viewed from the surface, it is simply silver (the color of the aluminum deposition layer). However, when the sealing seal 1 is peeled off, as shown in FIG. 8B, the transfer layer 4 and the pressure-sensitive adhesive layer 5 in the region in contact with the pattern-like peeling layer 3 remain adhered to the sealing object 8. For this reason, as shown in FIG. 8C, a pattern (for example, letters “VOID”) by the remaining transfer layer 4 is visible on the surface of the sealing object 8 and is opened. Remains. Moreover, even if the peeled seal 1 is pasted again, it cannot be pasted cleanly, and the trace of opening remains. In addition, the sealing seal shown in FIG. 7 is known in which the laminated structure is changed, but all of them are opened by leaving a part of the transfer layer provided on the sealing seal adhered to the sealing object. It is configured to leave traces of.

  Such sealing stickers are affixed to the opening of sweets or on PC software packages, and the latter is used to prevent malicious mischiefs and crimes. Used for confirmation. In any case, the purpose is to leave an opening history. The pattern to be formed on the release layer 3 is not limited to characters but may be provided in an endless pattern. When an endless pattern is used, a sealing seal of a free size can be obtained simply by partitioning with a half cut or the like.

  On the other hand, in order to prevent recent air terrorist incidents, inspection of passengers' luggage has become strict. Although we carry out strict checks regardless of whether they are brought on board, there is a possibility that suspicious items may be put in the baggage after checking. It took a lot of time and effort. In view of this, a method has been started to make it possible to accurately identify an inspected package by using a sealing seal as described above, and to make only a suspicious package even when rechecking. However, there are significant problems when using current seals on packages. That is, as shown in FIGS. 8B and 8C, the transfer layer 4 and the pressure-sensitive adhesive layer 5 remain in a package (for example, letters “VOID”). If the baggage is discarded after being used only once, there will be no problem even if the transfer layer or adhesive layer remains. For example, in the case of a suitcase, it will be used many times each time it is boarded. Therefore, there are serious problems such as (1) not knowing when the inspection was performed, and (2) fouling the passenger's belongings in the first place.

  The present invention has been made in view of such a situation, and when it is attached to a sealed object such as a suitcase and then peeled off, the adhesive or transfer layer does not remain attached to the sealed object. Nevertheless, it is an object of the present invention to provide a sealing seal capable of leaving a trace of opening.

In order to solve the above problems, the invention according to claim 1 of the present application is provided with an adhesive structure for attaching to a sealing object on the back surface of a sheet-like substrate, and a recording layer is formed in at least a partial region of the surface. An adhesive force suppressing layer that suppresses the adhesive force of the printing material or printing material to the base material is formed, and a recording layer is formed on the printing material or the printing material to form a sealing seal. When the sealing seal affixed to is peeled off, at least a part of the recording layer is peeled off by bending generated in the sealing seal.

  According to a second aspect of the present invention, in the sealing seal described above, a transparent film cover is further provided so as to cover the recording layer on the adhesive force suppressing layer.

  According to a third aspect of the present invention, in the sealing seal described above, the adhesive force suppressing layer is provided in a pattern, and the recording layer is provided with an adhesive force suppressing layer so as to conceal the patterned adhesive force suppressing layer. It is configured to be formed in a wide area including.

  The invention according to claim 4 is configured such that, in the sealing seal described above, a region where an adhesive force suppressing layer is not formed is left on the surface of the base material, and a recording layer is formed on the surface of the base material in a region called Li. It is.

The invention according to claim 5 is a sealing seal material for making the sealing seal described above, and has an adhesive structure for affixing to a sealing object on the back surface of a sheet-like substrate, and at least one of the surfaces. The recording layer is formed in a part area, the recording layer is formed thereon, the base material is attached to an object to be sealed, and then the recording layer is peeled off by bending that occurs in the base material when the base material is peeled off. It has the adhesive force suppression layer which suppresses the adhesive force with respect to the said base material of the printing material or printing material for forming a layer, It is characterized by the above-mentioned.

  When the sealing sticker having the above configuration is attached to a sealing object such as a suitcase, even if someone peels it off and puts it on again, the surface of the sealing sticker is recorded due to the bending that occurs in the sealing seal when it is peeled off At least a part of the layer peels off and falls off, and therefore the presence or absence of opening can be easily determined by looking at the surface of the sealing seal. Moreover, if it peels from a sealing target object after use, since there is no member which remains adhered to a sealing target object, a sealing target object is not soiled.

  Here, if a transparent film cover is provided so as to cover the recording layer on the adhesive force suppressing layer, the recording layer is protected by the transparent film cover even if the surface of the sealing seal is rubbed with something. Therefore, it can be used without any trouble even in a place where the sealing sticker or the object to be peeled off may be handled violently.

  Further, when the adhesive force suppressing layer is provided in a pattern and the recording layer is formed in a wide area including the adhesive force suppressing layer so as to conceal the patterned adhesive suppressing layer, sealing is performed. When the seal is peeled off, only the recording layer on the patterned adhesive force suppression layer is peeled off and dropped, and the pattern comes to float, so that the trace of opening remains, and the presence or absence of opening can be easily determined. .

  In addition, when a region where an adhesive force suppressing layer is not formed is left on the surface of the base material and a recording layer is formed on the base material surface of the region, the recording layer adheres firmly to the base material surface. Therefore, important information can be recorded on the seal.

  The sealing seal material of the invention according to claim 5 can be used as a sealing seal having the above-described configuration by printing or printing in a region where an adhesive force suppression layer is provided on the surface of the substrate.

Hereinafter, the present invention will be described in more detail with reference to the drawings. 1A and 1B are a schematic plan view and a schematic sectional view of a sealing seal 11 according to a basic embodiment of the present invention. The sealing seal 11 has an adhesive structure for adhering to the back surface of the sheet-like base material 12 in a form that can be peeled from the sealing object, for example, a pressure-sensitive adhesive layer 13 and a release sheet 14 for protecting it. and, at least in a partial region of the surface of the substrate 12, the printing material or printed to suppress adhesion inhibiting layer 15 adhesion thereon to the substrate 12 of the printed material or printing material for forming a recording layer A structure having a recording layer 16 formed of a material , and a structure in which at least a part of the recording layer 16 is peeled off and dropped due to a bend generated in the sealing seal 11 when the sealing seal 11 attached to an object to be sealed is peeled off. It is a thing. Here, the principle of the recording layer 16 peeling off due to the bending generated in the sealing seal 11 will be briefly described. As shown in FIG. 2A, when the sealing seal 11 is pulled in the direction of arrow A from the state where the sealing seal 11 is attached to the sealing object 20, the sealing seal 11 is peeled off while being bent. In this bent region, the recording layer 16 formed on the surface also bends. However, if the bending is large (the curvature radius is small), the material (toner, ink, etc.) forming the recording layer 16 is sealed. As shown in FIG. 2 (b), the recording layer 16 is removed when the peeled sealing seal 11 returns almost flat as shown in FIG. 2 (b). The material 16a to be formed partially peels off and falls off. This leaves a trace of opening.

  Since the peeling of the recording layer 16 generated in this way becomes larger as the adhesive force of the recording layer 16 to the base material 12 becomes weaker, in the present invention, the adhesive force suppressing layer 15 is formed on the surface of the base material 12, By forming the recording layer 16 in this manner, the adhesive force of the recording layer 16 to the substrate 12 is reduced. By the way, if the adhesive force is too small, the recording layer 16 may fall off simply by rubbing on the recording layer 16, so it cannot be reduced too much. On the other hand, the peeling of the recording layer 16 caused by the bending when the sealing seal is peeled off occurs more reliably as the bending of the base material 12 becomes larger (as the radius of curvature becomes smaller). Even if it is increased to a certain extent, if the bending of the sealing seal is increased, the recording layer 16 can be peeled off. Accordingly, the adhesive force suppressing effect of the recording layer 16 by the adhesive force suppressing layer 15 is moderately suppressed, and the adhesive force of the recording layer 16 to the substrate 12 is rubbed to a certain degree or more, for example, in order to apply a sealing seal. Or when the seal target is pasted, the recording layer 16 will have an adhesive strength that does not peel off or fall off even if the object hits the surface of the seal seal and rubs, and the seal is peeled off. By setting the bend to be larger than a certain degree, the recording layer 16 is peeled off and removed when leaving the recording layer 16 while preventing the recording layer 16 from being undesirably removed from the sealing seal. be able to. By the way, the magnitude of the bending that occurs when the sealing seal 11 is peeled off is determined by the adhesive strength of the sealing seal 11 to the sealing object and the stiffness (rigidity) of the substrate 12. That is, as shown in FIG. 3A, when the sealing seal 11 attached to the sealing object 20 is pulled and peeled in the direction of the arrow A inclined by a certain angle θ (referred to as the peeling angle) with respect to the sealing object. When the adhesive strength to the sealing seal 11 is large and the stiffness (rigidity) of the sealing seal 11 is small, the radius of curvature r of the bent portion is small (that is, the bending becomes large), and conversely the adhesive strength to the sealing seal 11 Is small and the stiffness (rigidity) of the sealing seal 11 is large, as shown in FIG. 3B, the radius of curvature r of the bent portion increases (that is, the bending increases). Therefore, when the sealing seal 11 is manufactured, as described above, the recording layer 16 can be peeled off and removed when it is peeled off while preventing the recording layer 16 from being undesirably dropped off. Properties such as the adhesive strength of the recording layer 16 to the base material 12, the adhesive strength of the sealing seal to the sealing object, and the stiffness (rigidity) of the base material 12 may be set.

  As a result of confirmation by the present inventors, the recording layer 16 is obtained when the curvature radius r of the bent portion is larger than about 5 mm when the sealing seal 11 attached to the sealing object 20 is peeled off at a peeling angle θ = 90 °. However, when the adhesive strength of the recording layer 16 was set so that the peeling would be increased below that, a good result was obtained. Therefore, in selecting the characteristics of each part of the sealing seal 11, this may be used as a guide.

  As the base material 12 of the sealing seal 11, a sheet-like material such as paper, synthetic paper, and resin sheet can be used as appropriate. Further, when it is desired to form a recording layer by printing, printing or the like so as not to drop off in a partial region of the base material 12, a material having good adhesion to printing toner or ink, for example, paper may be used. preferable. When paper is used as the base material 12, it is preferably 150 μm or less so that the radius of curvature r of the bent portion when peeling is reduced. The adhesive structure provided on the back surface of the base material 12, for example, the pressure-sensitive adhesive layer 13, has a moderately large adhesive strength with respect to the sealing object to which the sealing seal 11 is applied, and the curvature radius r when peeling off satisfies the above-described conditions. Set to. In addition, since the adhesive strength of the adhesive structure provided on the back surface of the substrate 12 varies depending on the physical properties of the object to be pasted, the surface state, and the like, strictly speaking, there is a suitable use range depending on the sealing object, As the inventors have confirmed, among the adhesive strength measuring methods in “JIS-Z0237: 2000”, the adhesive strength measured by the “90 ° peeling method” is 1.2 N / 10 mm or more. It was applicable to the sealed object. Therefore, the adhesive strength may be determined using this as a guide.

  The adhesive force suppressing layer 15 formed on the surface of the substrate 12 is provided to suppress the adhesive force of the recording layer 16 to the substrate 12 as described above, and is a material (printing toner, It can be formed by applying a resin material having a low adhesive force to the surface of the substrate 12 by printing, coating, laminating or the like. More specifically, examples of the material for forming the adhesive force suppressing layer 15 include UV curable resins such as UV curable acrylic resins, which are difficult to adhere to printing toners, ink ribbons, and the like. In addition, a release (release) component typified by silicone may be put therein. In the case where the recording layer 16 is formed by printing variable information on the sealing seal 11 with various printers, the adhesive force suppression layer 15 is formed only by the UV curable resin, so that it is necessary for the printing toner or the like. An adhesive force suppressing effect can be obtained. The region where the adhesive force suppression layer 15 is formed may be the entire surface of the substrate 12 or a partial region. Moreover, the adhesive force suppressing layer 15 may be formed in a solid shape over the entire region where it is formed, or may be formed in a pattern shape such as letters.

  The recording layer 16 on the adhesive force suppressing layer 15 may be formed by various printers or may be formed by printing by various printing machines, but it is particularly preferable to print variable information by a printer. If the variable information is printed by the printer, the variable information can be recorded as well as the trace of opening. Further, when a toner fusion type printer is used as the printer, it is possible to print the toner in a form in which the toner is suitably removed easily on the adhesive force suppression layer 15 formed only by the UV curable acrylic resin. The advantage that the sealing seal 11 provided with the adhesive force suppression layer 15 which can be formed at cost can be used is obtained.

  Next, an example of a method of using the sealing seal 11 having the above configuration will be described. In a factory, an adhesive structure is formed on the back surface of the base material 12 and an adhesive force suppressing layer 15 is formed on the front surface (sealing seal material 11 in FIG. 1 in which the recording layer 16 is not formed). Material) and supply it to the place of use (eg airport). At the place of use, variable information is recorded on this sealing seal material by a printer, a recording layer 16 is formed, and the sealing seal 11 of FIG. 1 is created. And the sealing seal | sticker 11 is affixed on sealing objects, such as a passenger's luggage. If someone tries to peel off the sealing seal 11, as shown in FIG. 3A, the sealing seal 11 is peeled off while being bent rapidly, and the recording layer 16 peels off due to the bending, and falls off. End up. For this reason, even if the peeled seal 11 is attached again, the characters and patterns of the recording layer 16 on the surface of the seal 11 are in a disordered state. Thus, the presence or absence of opening can be easily determined. After use, the sealing seal 11 is peeled off from the sealing object and discarded. At this time, unlike the conventional sealing seal, the transfer layer does not remain adhered to the sealing object, so that the sealing object is not soiled. Thus, by using this sealing seal 11, it is possible to easily determine whether or not the seal is opened, and to obtain an effect that the sealed object is not soiled.

  Although the basic embodiment of the sealing seal of the present invention has been described above, various modifications can be made to the sealing seal of the present invention. FIG. 4 shows a sealing seal 11A according to the second embodiment. The sealing seal 11A is provided with a transparent film cover 22 so as to cover the recording layer 16 formed on the adhesive force suppressing layer 15, and is attached by an adhesive 23 at a position that does not cover a character portion to be peeled off of the recording layer 16. The structure is affixed to the adhesive force suppression layer 15. If the transparent film cover 22 is provided in this way, the recording layer 16 can be formed even if the surface of the sealing seal 11A is rubbed when the sealing object to which the sealing seal 11A is stuck is thrown into the cargo room. The recording layer 16 is not scraped off without being rubbed directly, and the advantage that it can be used with confidence is obtained.

  FIG. 5 shows a sealing seal 11B according to the third embodiment. In this sealing seal 11B, the adhesive force suppressing layer 15B formed on the surface of the substrate 12 is formed in a pattern shape such as a letter “VOID”, for example, and the patterned adhesive force suppressing layer 15B is concealed. The recording layer 16B is formed in a solid or tint pattern in a wide area including the adhesive force suppressing layer 15B. In the sealing seal 11B having this configuration, when peeled off, only the recording layer 16B located on the pattern-like adhesive force suppressing layer 15B is dropped, whereby the pattern of the adhesive force suppressing layer 15B (for example, letters “VOID”) is formed. It will float and leave a trace of opening.

  FIG. 6 shows a sealing seal 11C according to the fourth embodiment. The sealing seal 11C has an adhesive force suppressing layer 15C formed on both end portions of the surface of the base material 12, a recording layer 16C is formed thereon, and an adhesive force suppressing layer 15C of the base material 12 is not formed. A permanent recording layer 25 on which desired information is printed or printed is formed in the area. With the sealing seal 11C, it is possible to record important information on the base material 12 as a permanent recording layer 25 that does not drop off.

  As described above, the sealing seal of the present invention is suitable for use on an airport passenger's baggage. However, the sealing seal is not limited to this. It can also be used for purposes such as sticking to a PC software package or preventing tampering by attaching it to a PC software package, and can be used for any other application where it is necessary to leave a trace of opening.
