Abstract

PROBLEM TO BE SOLVED: To obtain the lowcost resticking preventive seal which eliminates the need for member management and additional operation at sticking time by forming a transferrable pattern layer representing characters, a pattern, etc., on a surface that a stuck body comes into contact with. SOLUTION: An alteration preventive seal 1 is constituted by forming an adhesion surface 3 on the reverse surface of a seal main body 2 formed of a transparent film which is thick enough to easily expand or break. On an adhesive surface 3 as the surface that comes into contact with a stuck body, a print using transferrable ink or a pattern layer 4 having a repetitive pattern of microcapsules for no-carbon copying is formed. When this seal 1 is used in a subordinate seal field of a bankbook as the adhered body, the pattern layer 4 is in contact with the surface of the bankbook, so the character pattern is transferred to the bankbook. Therefore, when somebody tries to stick a new seal 1 after peeling the seal 1 and altering the seal impression, it is difficult to match the pattern and stick the seal, and the restricking can substantially be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a replacement preventive seal.

[0002]

2. Description of the Related Art Conventionally, a replacement prevention seal is, for example,
It is used to prevent falsification of passbooks. In this case, a replacement preventive seal made of a thin film that stretches or breaks as soon as it is pulled is attached to the passbook so as to cover the stamped part of the passbook holder's seal, and the seal is peeled off to falsify the seal imprint. If you try to re-attach it afterwards, tampering is prevented by making the re-evidence traces such as wrinkles and tears appear on the seal. However, with this method, if a new seal is available, it can be replaced, so it is necessary to manage the number of new seals.

In addition to this, in order to prevent the replacement, for example, a seal is provided between an adherend such as a passbook and a seal, or a cyanoacrylate adhesive is used to prevent the seal from being extremely peeled off. There are cases where special adhesives such as adhesives and two-component mixed adhesives are used, but the former is troublesome in the work of tallying and the latter is difficult and expensive to handle. Was a problem.

[0004]

As described above, the conventional anti-replacement sticker requires management of the number of stickers, additional work such as a tally other than sticking the sticker, or a special sticker. There was a problem that the cost was high due to the adhesive. Therefore, a technical problem to be solved by the present invention is to provide a replacement preventive seal which does not require the management of the number of members and an additional work at the time of sticking, and is low in cost.

[0005]

[Means for Solving the Problems and Actions / Effects] The replacement preventive seal according to the present invention easily extends or breaks,
A translucent thin seal body having an adhesive surface formed on the back surface of the main body, which is a replacement preventive seal, and is provided with a transferable pattern layer representing characters or patterns in order to solve the above technical problems. It is characterized in that it is formed on the contact surface with.

In the above structure, the pattern layer may be composed of a printing surface made of transferable ink or a layer of microcapsules for carbonless copying. As the transferable ink, for example, one in which a dye is dissolved in a non-drying oil, one in which a pigment is mixed with an acrylate-based ink that does not contain a solvent that affects the adhesive surface, and further,
It is possible to use an ink that does not dry for a long period of about 1 to 2 years, such as an ionizing radiation curable ink such as an ultraviolet curable ink without a crosslinking initiator (sensitizer). In addition, as the carbonless microcapsules, a color developer and a color developer may be integrated, or the color developer and the color developer may be separately used on the seal side and the adherend side. .

Further, the ionizing radiation curable ink includes acrylates such as urethane acrylate, polyester acrylate and epoxy acrylate, silicon resins such as siloxane, resins such as polyester and epoxy, and a polymerizable unsaturated bond in the molecule, or It is possible to use an ink composed of a composition in which a pre-oligomer having an epoxy group, an oligomer, and / or a monomer are appropriately mixed.

When the replacement preventive seal having the above-mentioned structure is attached to an adherend, when the pattern layer is made of transferable ink, the pattern layer comes into contact with the surface of the adherend, and also the micro carbon for carbonless copying. In the case of a capsule, when the surface of the seal is rubbed and adhered well to the adherend at the time of sticking, the pattern of the pattern layer is transferred to the surface of the adherend. Therefore, when the seal is peeled off, the pattern remains on the surface of the adherend. For this reason, since the pattern works in the same manner as the tally mark, it is difficult to attach the patterns together even if another sticker is used. Therefore, if this sticking prevention seal is put on the stamped portion and attached to the passbook, it is possible to prevent the passbook from being illegally used due to falsification of the seal imprint.

As described above, according to the above construction, even if a new seal is obtained, it cannot be replaced if the adherend has a pattern, so that it is not necessary to manage the number of seals, thereby reducing the labor and cost. it can. Further, since there is no need for work other than sticking a seal such as a tally mark, there is no complication when using it, and cost reduction is possible because no special material is used.

Further, in the above structure, the pattern layer is composed of a continuous pattern having a repeating pattern, and a plurality of seals are formed with the same repeating pattern having different starting and ending positions of the pattern. Is preferred. A replacement preventive seal having such a pattern layer forms a continuous pattern layer having a certain repeating pattern on the adhesive surface at the stage of the sheet before cutting out the seal, and this sheet is referred to as a pattern repeating pattern. It can be manufactured by cutting at different pitches.

It is difficult to match and replace the seal patterns even if all the seal layers have the same pattern layer. However, by changing the pattern of the continuous patterns of a plurality of seals in this way, Almost completely impossible,
The replacement can be prevented more reliably.

Further, when the pattern layer is formed of a continuous pattern in this manner, the same pattern can be formed at a ratio of one to several for the convenience of production. In that case, a backing paper for concealing the pattern of the pattern layer is used. If the sticker is releasably attached to the surface of the sticker body, the picture layer cannot be seen when the sticker is stuck, so that it is possible to more reliably prevent the picture from being reattached. Further, by using a backing paper, it is possible to make the seal main body extremely thin, and to make the seal main body alone stretch or break.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below.
This will be described in detail with reference to FIGS. 1 to 7.

First, FIG. 1 shows a first example of the embodiment.
This will be described with reference to FIG. FIG. 1 is a sectional view showing the laminated structure of this seal. The tamper-proof seal 1 has a structure in which an adhesive surface 3 is formed on the back surface of a seal body 2 made of a transparent film having a thickness that easily extends or breaks, and is an adhesive surface that is a contact surface with an adherend. A pattern layer 4 having a repetitive pattern formed on the surface 3 by printing with a transferable ink or by microcapsules for carbonless copying.
Are formed. Further, 5 is a release paper, and a seal 1
The adhesive surface 3 is covered entirely.

FIG. 2 is a perspective view showing an example of a working mode of the seal 1 and a method of using it. FIG. 2A shows a sheet in which a release paper 5 is attached to the back surface of the sticker 1,
The pattern layer 4 is shown as being formed by repeating a continuous character pattern. To separate individual seals,
The seal 1 and the release paper 5 are cut together at the line connecting ~, only the seal 1 is cut at the line connecting ~, and only the release paper 5 is cut at the line connecting ~. In addition, the individual seals 1 are arranged at a pitch different from the repetition of the character pattern, whereby
The character pattern of the picture layer 4 is different for each sticker 1. Although a simple example is shown in the figure, if the pattern of the pattern layer and the arrangement of the seals are appropriately set, the number of patterns for each seal can be almost unlimited.

With the above-described cut patterns described with reference to symbols, the release paper 5 has only the portion 5a corresponding to the pattern layer 4 cut out as shown in FIG. 2 (b).
A hole 5b is formed on the main body side of the release paper 5. Therefore, the sticker 1 is such that the tab-shaped portion on which the pattern layer 4 is formed is pinched with the release paper 5a attached, peeled off from the release paper 5, and attached to the adherend at a predetermined position, and then the pattern layer 4 is attached. It is sufficient to remove the covering release paper 5a and attach the whole to the adherend. According to this structure, it is possible to prevent the transfer ink from smearing the hand or making the pattern unclear when the sticker 1 is attached.

FIG. 3 is a perspective view showing an example in which the seal 1 is used for a sub-seal stamp section of a passbook 10 as an adherend, and FIG. 4 is an enlarged sectional view taken along line IV-IV of FIG. After imprinting, the seal 1 is attached so as to cover the imprint 11 by the method described with reference to FIG. Since the pattern layer 4 is in contact with the surface of the passbook 1, the character pattern is 10
Transcribed to Therefore, if you try to attach a new sticker 1 after peeling off the sticker 1 and falsifying the seal imprint,
Since the character pattern has already been transferred, even if the seal 1 having the same pattern is obtained, it is very difficult to attach the patterns together and it is possible to substantially prevent the replacement.

As described above, according to the above structure, even if a new seal is obtained, the replacement of the seal can be prevented, so that the management of the seal becomes unnecessary and the labor and cost therefor can be reduced.
Further, since there is no need for operations other than sticking a seal, such as marking, there is no complication when using, and cost reduction is possible because no special material is used.

5 (a) and 5 (b) respectively show modifications of this embodiment. In the above-mentioned example, it is conceivable that the ink of the pattern layer 4 may permeate the adhesive surface 3 in some cases, and sufficient transfer performance cannot be obtained when the ink is adhered to an adherend. On the other hand, in the example shown in FIG.
First, a permeation preventive layer 6 is formed on the adhesive surface 3 with a transparent ultraviolet curable ink or the like, and then a pattern layer 4 is formed thereon. Further, in the example shown in FIG. 5B, a blank portion 3a not coated with the adhesive is provided on a part of the adhesive surface 3, and the pattern layer 4 is directly formed on the seal body 2 in the portion 3a. ing. In these examples, sufficient transfer performance is ensured by preventing ink from penetrating into the adhesive surface 3,
It is possible to more reliably prevent unauthorized replacement. In particular, FIG.
By forming the adhesive surface 3 on the right side of the pattern layer 4 as shown in FIG.
By cutting the periphery of only the seal 1 without making a cut as shown in, the sticker 1 is attached so as to cover the imprint 11 by holding the right adhesive surface 3 with a finger without touching the pattern layer 4. It will be possible to wear.

Next, a second example of the embodiment will be described with reference to FIG.
And FIG. 7 will be described. FIG. 6 is a perspective view showing a state in which a replacement prevention seal is attached to a passbook to which a seal stamp is attached, and FIG. 7 is a sectional view taken along line VII-VII of FIG. The seal stamp 12 is constructed by pressing a seal stamp on the base material sheet 13 and then laminating it with a seal 14 so as to cover the seal imprint 11, and is used by transferring to a new passbook each time the passbook is carried over. In this example, the seal body 2 is composed of a film (thickness of about 12 μm or less) which is thin enough to prevent re-adhesion by itself in order to prevent re-adhesion, and is shown in FIG. 2 in the first example described above. In the processed form, an opaque backing paper is releasably attached to the entire surface.

The seal 1 has a structure in which the backing paper 7 which is releasably laminated on the seal body 2 is attached to the passbook with the sticker body 2 being attached thereto, and the backing paper 7 is then peeled off, as shown by phantom lines in FIG. . That is, at the stage of applying the seal 1, the pattern layer 4
Since it is hidden by the backing paper 7, it is virtually impossible to match the patterns when they are replaced. It should be noted that, as in the first example described above, the management of the seal and the work of tallying are unnecessary, and that no special material is required.

Here, for the transparent film in the first and second examples of the embodiment, which has a thickness such that it easily stretches or breaks, a flexible and highly stretchable polyolefin resin is suitable, Low density polyethylene, polypropylene, ethylene-vinyl acetate copolymer and the like can be preferably used. In particular, in the case of the second example, since the seal body 2 is so thin that it cannot be attached by itself, the low-density polyethylene that constitutes the seal body 2 directly on the backing paper 7 or through the release layer. It is suitable to form a polyolefin resin such as by hot melt extrusion lamination. By forming in this way, the surface of the seal main body 2 is tacky when the backing paper 7 and the seal main body 2 are temporarily attached and peeled off without requiring a sheet for supporting the seal main body 2. It becomes possible to laminate as the thing which does not have.
