Description

Description: BACKGROUND OF THE INVENTION [0001] The present invention relates to
The present invention relates to a sealing paper which is prevented from peeling, and more particularly to a sealing paper suitable for use in a control board box of a game machine. 2. Description of the Related Art Conventionally, as this kind of sealing paper, a sealing paper applied to a control board box of a game machine shown in FIG. 6 is known. The substrate box 1 is formed by combining a pair of rectangular shallow dish-shaped casings 3 and 4 with their opening surfaces facing each other, and can be opened and closed as necessary. However, the sealing paper 2 is attached so as to straddle the side walls 3a and 4a of the casings 3 and 4, respectively. Has become. [0003] The above-mentioned conventional sealing paper has the following problems. In some cases, it is possible to remove the sealing paper without leaving any trace by using a solvent or the like and applying heat to the bonded sealing paper with a drier or the like. there were. [0005] In order to solve the above-mentioned problems, the invention according to claim 1 is a method in which an adhesive is applied to a back surface of a sealing paper which can be pasted, and the sealing paper is attached. In the process of peeling from the state, a structure is provided with microcapsules that leak a predetermined substance inside to prevent reuse after peeling. According to the first aspect of the present invention, if a predetermined substance is removed from the microcapsules by applying heat or using a solvent to the adhered sealing paper and peeling it off. Leaks out. This leakage leaves traces of exfoliation. As described above, the present invention can be applied to a control board box or the like of a game machine, since it can be prevented from being used again by leaving a trace when it is peeled off after pasting. Thus, it is possible to provide a seal paper that can more strictly restrict acts such as unauthorized remodeling. [0008] Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a control board box of a gaming machine to which a sealing paper according to an embodiment of the present invention is applied. In the figure, control board box 1
0 is formed by combining a pair of rectangular shallow box-shaped casings 11 and 12 such that their opening faces face each other,
A control board for controlling game contents of a gaming machine (not shown) is stored therein. The sealing paper 20 described later is the casing 1
The control board box 10 cannot be opened unless the sealing paper 20 is peeled off, since it is stuck so as to straddle the side walls 11a and 12a of the first and the second side 12, respectively. In the present embodiment, the sealing paper 20 is applied to the control board box 10 of the gaming machine. However, the sealing target is not necessarily limited to the control board box 10; It can be applied to the sealing of the opening and closing of other casings such as boxes or paper containers such as envelopes, or if it is a sealing paper that can see through the sealing surface, cover the sign and the stamped part of the document. It is also possible to apply to a simple seal. FIG. 2 schematically shows a cross section of the sealing paper 20. The sealing paper 20 is printed with ink 22 containing microcapsules 22a that break down at a predetermined temperature or more on the surface of a paper 21 cut into a rectangular shape, and an adhesive 23 is applied and adhered to the back surface thereof. It is possible.
The microcapsules 22a contain ink of a different color from the ink 22. When the sealing paper 20 is peeled off and heated by a drier or the like to reach a predetermined temperature or higher, the microcapsules 22a collapse and leak the contained ink, thereby discoloring the print. With such a configuration,
Even if the sealing paper 20 is peeled off while being heated, it can be seen at a glance that the printing has changed color, so that it cannot be reattached. In the present embodiment, the sealing paper 20 is printed with ink containing microcapsules on the surface of the rectangular paper 21 and an adhesive 23 is applied to the back surface so that the sealing paper 20 can be attached. It suffices that an adhesive can be applied to the back surface and adhered while using microcapsules containing a predetermined substance inside. Therefore, the shape and the material are not particularly limited, and the printing location can be appropriately changed as long as it can be visually recognized from the outside. For example, in a sealing paper 30 using a film material whose cross-sectional schematic diagram is shown in FIG. 3, a back surface of a transparent film material 31 is printed with ink 32 mixed with the same microcapsules 32a as described above, The adhesive 33 can be applied and attached. Also in this case, when heated, the microcapsules 32a collapse and the ink different in color from the encapsulating print leaks out and discolors the print. However, since the print can be seen through the surface of the sealing paper 30, the heating is performed. It can be seen at a glance even if the color changes. In this case, the microcapsules 32 are attached to the adhesive 33.
a may be mixed. Further, it is not necessary to mix the microcapsules in the ink used for printing, and the sealing paper itself contains the microcapsules and is heated so that the sealing paper is discolored as a whole. Is also good. With such a configuration, the sealing paper that has been heated and peeled off without any particular printing can be seen at a glance. In the present embodiment, the microcapsules that disintegrate when heated are used. However, it is only necessary to be able to disintegrate in the process of peeling and to allow the contained substance to leak out, and it is not necessary to be limited to the microcapsules that disintegrate by heating. For example, when peeling the sealing paper, it may be performed while heating as described above, but since it is conceivable to peel the sealing paper while using some solvent for the adhesive, it is dissolved in a predetermined solvent and included. Microcapsules that allow substances to leak may be used. Needless to say, microcapsules having both properties such that they disintegrate by heating and dissolve in a predetermined solvent are more effective. In the sealing paper 20 according to the present embodiment, the ink is encapsulated in the microcapsules 22a, and when heated, the microcapsules collapse and the ink inside leaks, thereby discoloring the sealing paper 20 and reusing it. Although it is prevented, if it is peeled off after application, it is sufficient if it can be seen that the film has been peeled off leaving some trace, and it is not necessary to be bound by the above configuration. For example, a sealing paper 40 using microcapsules containing a substance that changes the adhesive ability of the adhesive whose schematic cross section is shown in FIG. 4 may be used. In the figure, an adhesive 42 is applied to the back surface of the mount 41 so that it can be adhered, and an adhesive 43 mixed with microcapsules 43a is applied to the surface of the mount 41, and a cover 44 is further placed thereon. Is adhesively fixed. The microcapsules 43a contain a substance that causes the adhesive ability of the adhesive 43 to disappear, and when heated, disintegrate and leak the substance inside. Therefore, if the heating is performed for the peeling, the adhesive ability of the adhesive 43 is lost, and only the cover 44 is peeled off, leaving a trace. Although a layered structure is used in this example, it may be separated into different parts on a plane as shown in FIG. In the figure, a cut is formed between a printing portion 51 of a sealing paper 50 and a frame portion 52 surrounding the periphery thereof, and the cut portion includes a substance which loses the adhesive ability of the same adhesive as described above. And fixed by an adhesive 53 mixed with microcapsules. In addition, the sealing paper 50
A different adhesive is applied to the back side of the device so that it can be attached. With this adhesive 53, it becomes possible to stick as a single piece of paper as usual during the sticking operation. However, when the sealing paper 50 is heated, the adhesive ability of the adhesive 53 is lost. Therefore, when the sealing paper 50 is to be peeled, a cut portion is opened, only the frame portion 52 is peeled, and the printing portion 51 remains. At this time, since the slightly remaining joint portion is cut, a trace can be surely left. Further, as a means for disintegrating the microcapsules during the peeling process, a case where a strong pressure is applied may be used. For example, the microcapsules may be collapsed when a razor blade or the like is strongly inserted between the sealing surface and the adhesive surface while pulling the sealing paper 20 to peel off the sealing paper 20. At this time,
The pressure may be received by the razor blade, or the pressure may be received by the force of strongly pulling the sealing paper. If these are classified, means for disintegrating the microcapsules include heat, solvent, pressure, etc., and traces of disintegration include discoloration and loss of adhesive ability. The application place is in the ink, on the front and back surfaces of the sealing paper, inside, or in an adhesive, and in some cases, it can be applied to the film itself. As described above, the microcapsules 22a containing the predetermined substance
If the sealing paper 20 on which printing or the like has been applied with ink mixed with is tried to be peeled off by heating or using a certain solvent, the microcapsules 22a collapse and leak a predetermined substance to discolor the printing. This leaves traces that cannot be used again.
