Description

  The present invention relates to a seal and a container for sealing an opening of a container in which an article is stored.

  2. Description of the Related Art Conventionally, in game machines such as pachinko machines and pachislot machines, ROM (ROM) in which a program for controlling the winning probability and the like is stored is accommodated in a box-shaped circuit box arranged in the game machine. In these game machines, a fraudulent act is performed in which the ROM stored in the circuit box is replaced with a fraudulent ROM having a different winning probability. Therefore, a sealing seal is attached to the lid of the circuit box and sealed.

If a normal seal is used as the seal seal, it is relatively easy to remove the seal seal without deteriorating the appearance and perform the above-mentioned fraudulent act. Sometimes used as a seal. For example, Patent Document 1 describes an easily breakable patch that is designed such that the adhesive strength is greater than the breaking strength of the seal substrate.
JP 61-226784 A

  However, in the patch described in Patent Document 1, the relative relationship between the breaking strength and the adhesive strength of the sealing base material changes depending on the temperature. Generally, the strength and viscosity of a resin material used as a pressure-sensitive adhesive decreases as the temperature rises. Therefore, when the temperature of the base material and the pressure-sensitive adhesive is increased using a heating means, the adhesive strength decreases. It may be smaller than the breaking strength of the seal substrate. In this case, there is a problem that it is possible to remove the patch without destroying it, and it is easy to cheat.

  In addition, since many of the adhesives used in the above-mentioned adhesive material are dissolved in an organic solvent, there is a problem that if an appropriate organic solvent is used, it can be removed without leaving a trace, and illegal acts are possible. .

This invention is made | formed in view of the said situation, and it aims at providing the sealing seal | sticker which is difficult to peel without impairing an external appearance.
Another object of the present invention is to provide a container that is difficult to open illegally without leaving a trace.

The sealing seal according to the first aspect of the present invention is provided on a base material, a printed layer provided on the first surface of the base material, and a second surface opposite to the first surface of the base material. A sealing seal having an adhesive layer, wherein the base material has a pair of slits having convex portions facing each other with the convex portions facing outward, and the base material, It is formed from the first surface to the second surface, and the pair of slits are arranged such that each of the convex portions is located within a predetermined distance from the peripheral edge of the base material, and at least of the pair of slits One is characterized by having a bent portion formed by bending at least one end portion .

According to the seal seal of the present invention, the upward tensile load applied when the seal seal is to be peeled is concentrated on the end portion of the slit and easily broken. Even if an attempt is made to peel from the end side of one slit so as not to concentrate the load on the end portion, the tensile load is always concentrated on the end portion of the other slit.
In addition, the shape of the end becomes complicated, and it becomes difficult to predict the action of the stress caused by the tensile load, making peeling difficult.

  The base material may be formed of a brittle material that is broken by a force equal to or lower than the adhesive strength of the adhesive layer. In this case, the substrate is easily broken at the time of peeling, and peeling becomes more difficult.

  The sealing seal of the present invention further includes a release paper attached to the side of the adhesive layer opposite to the surface on which the base material is provided, and the pair of slits are positioned at the lower ends thereof inside the release paper. Alternatively, it may be formed by a laser beam. In this case, since the release paper is not cut, it is possible to form a seal seal that is easy to stick at the time of sealing.

The container according to the second aspect of the present invention includes a housing body having a housing in which an article is housed, a lid attached to the housing so as to be openable and closable, the housing and the lid. A sealing seal adhered to the container body so as to straddle , the sealing seal including a substrate, a printed layer provided on the first surface of the substrate, and the first surface of the substrate. An adhesive layer provided on the second surface on the opposite side, and the base member has a pair of slits having convex portions facing each other with the convex portions facing outward, and the first Formed from one surface to the second surface, the pair of slits are arranged such that each of the convex portions is located within a predetermined distance from the periphery of the base material, and the housing and the lid Are formed with a first recess and a second recess, respectively, and the sealing seal is the pair of seals. Characterized in that the base of the inner slit is bonded to the housing body so as to adhere to the first recess and the second recess, respectively.

  According to the container of the present invention, it is difficult to peel and open the seal seal without destroying the base material, and it is difficult to perform illegal acts such as replacing an article housed inside. Even if it is performed, the trace of the fraudulent act remains, and the existence of the fraudulent act can be easily detected.

According to the seal seal of the present invention, it is possible to provide a seal seal that is difficult to peel without impairing the appearance.
Moreover, according to the container of the present invention, it is possible to provide a container that is difficult to open illegally without leaving a trace.

Hereinafter, a sealing seal and a container according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6.
FIG. 1 is a perspective view showing a circuit box (container) 1 of the present embodiment. The circuit box 1 is stored inside a game machine such as a pachinko machine, and accommodates a ROM (not shown) in which a program for controlling the winning probability is stored.
As shown in FIG. 1, the circuit box 1 includes a box body (container body) 4 having a housing 2 and a lid 3, and a seal seal 5 bonded to the lid 3.

FIG. 2 is a plan view of the seal seal 5, and FIG. 3 is a cross-sectional view taken along line AA of FIG. As shown in FIGS. 2 and 3, the seal 5 is opposite to the sheet-like base material 6, the printed layer 7 provided on the first surface 6 </ b> A of the base material 6, and the first surface 6 </ b> A of the base material 6. An adhesive layer 8 provided on the second surface 6B on the side and a release paper 9 attached to the adhesive layer 8 are provided.
In FIG. 2, the printing layer 7 is omitted to make it easier to see a first slit and a second slit described later.

The substrate 6 is preferably made of a brittle material that can be broken and broken with little plastic deformation, and more preferably broken by a tensile load smaller than the adhesive strength of the adhesive layer 8.
Specifically, a paper or resin having a low strength, a filler added in a large amount, a brittle resin material such as a biodegradable resin, or the like can be employed.

  The printing layer 7 is an arbitrary pattern composed of characters, images, lattices, etc., alone or in combination, using various known printing inks for offset printing, silk screen printing, gravure printing, flexographic printing. It can form by well-known printing methods, such as. The printed layer 7 changes its appearance due to distortion or the like when an external force is applied to the substrate 6, so that it becomes a trace of fraud and the like, and has a function of improving its visibility.

The adhesive layer 8 is for adhering the seal seal 5 to an object such as the box main body 4 to be sealed. As a material of the adhesive layer 8, various known adhesive materials such as an acrylic adhesive material, a polyester adhesive material, and a urethane adhesive material can be employed.
The adhesive layer 8 can be formed by fixing these pressure-sensitive adhesive materials to the second surface 6B of the substrate 6 by the above-described various printing methods and coating methods, and the thickness thereof is 1 if necessary. It can set suitably in the range of about -20 micrometers (micrometer).

  The release paper 9 is for protecting the adhesive layer 8 until the seal seal 5 is adhered to the object, and is configured such that one side is subjected to silicon treatment or the like and can be easily peeled off from the adhesive layer. A known release paper can be employed.

  As shown in FIG. 2, a pair of first slits 10 and second slits 11 are provided on the upper surface of the substrate 6. Each of the slits 10 and 11 is formed in a substantially semicircular shape, and the vicinity of the respective midpoints 10A and 11A is a convex portion that is convex in a substantially arc shape (in the following description, the midpoint 10A and the midpoint) 11A is referred to as a convex portion 10A and a convex portion 11A, respectively, as necessary.)

  The slits 10 and 11 are formed so as to face each other in a state in which the convex portions 10A and 11A face the peripheral edge side of the nearest base material 6, respectively. Moreover, each slit 10 and 11 is arrange | positioned so that each convex part 10A and 11A may be located in predetermined distance, for example within 5 mm, from the periphery of the base material 6 which is respectively the nearest.

  As shown in FIG. 3, each slit 10, 11 is formed so as to penetrate the printing layer 7, the substrate 6, and the adhesive layer 8, and the lower end thereof is a surface 9 </ b> A on the adhesive layer 8 side of the release paper 9. And reaches the middle in the thickness direction of the release paper 9.

  Each of the slits 10 and 11 can be formed by a cutter, a high-power laser beam, or the like, and may be formed by punching using a mold. In the present embodiment, the slits 10 and 11 are formed using a laser beam.

  FIG. 4 is a cross-sectional view of the box body 4. As shown in FIG. 4, the housing 2 is formed in a substantially box shape, and a ROM (not shown) can be accommodated therein. The lid 3 is attached to the upper surface of the housing 2 via a hinge 12 and can be opened and closed with the hinge 12 as a rotation axis.

In the vicinity of the end 3 </ b> A opposite to the hinge 12 on the upper surface of the lid 3, a first recess 13 having a shape that gradually becomes deeper toward the hinge 12 is provided by means such as cutting or embossing. On the upper surface of the housing 2 near the end 3 </ b> A, a second recess 14 having a shape that becomes gradually deeper as the distance from the lid 3 is increased is formed in the same manner as the first recess 13.
The first recess 13 and the second recess 14 are formed so as to have substantially the same shape as the first slit 10 and the second slit 11 of the seal seal 5 in plan view, respectively.

  FIG. 5 is a cross-sectional view showing a state in which the seal seal 5 is bonded to the box body 4. As shown in FIG. 5, the seal seal 5 is bonded so that the first slit 10 and the second slit 11 are located above the first recess 13 and the second recess 14, respectively.

  Furthermore, the base material 6 located inside each slit 10, 11 is bent downward with lines L1 and L2 connecting both ends of each slit 10, 11 shown in FIG. 2 as fold lines, as shown in FIG. They are respectively bonded to the first recess 13 and the second recess 14.

  According to the seal seal 5 of the present embodiment, since the first slit 10 and the second slit 11 are provided on the base material 6, when a tensile load is applied upward in an attempt to peel off illegally, each slit 10, 11 , The base material 6 is separated into a peripheral edge side and a tongue-shaped inner part, and only one of them is pulled upward.

  For this reason, even if any of the slits 10 and 11 of the base material 6 is pulled up on the peripheral side and inside the slits 10 and 11, the stress generated by the tensile load is concentrated on both ends of the slit, and both ends are distorted. It becomes easy to rip or break. Accordingly, it is possible to form a sealed seal that is difficult to peel without impairing the appearance, and that traces are likely to remain even if peeled off.

  When the base material 6 is peeled from the end portion side of the slit, it is possible to pull up the inner side and the peripheral side of the slit integrally without concentrating stress on the end portion of the slit. However, since the first slit 10 and the second slit 11 are formed so as to face each other with the respective convex portions 10A and 11A facing the peripheral edge of the nearest base material 6, for example, the first slit 10 If the sealing seal 5 is to be peeled from the end of the second slit 11, the second seal 11 is peeled from the convex portion 11 </ b> A side, and stress due to the tensile load is concentrated on both ends of the second slit 11.

  Therefore, unless the substrate 6 is cut in the vicinity of the center portion, it is difficult to pull the inner side and the peripheral side of the slit together to separate them, and in this way, traces of fraud etc. remain clearly. It becomes. Therefore, it is possible to constitute a sealed seal that is more difficult to peel without impairing the appearance.

  In addition, if the base material 6 is formed of a brittle material that is broken by a tensile load smaller than the adhesive strength of the adhesive layer 8, the base material 6 is easily broken and broken during peeling, so that the appearance is not impaired. It becomes more difficult to peel off the seal 5.

  Furthermore, since the printing layer 7 is provided on the base material 6, distortion, tearing, and the like generated on the base material 6 can be easily recognized by the disturbance of the printing layer 7. Therefore, it is possible to configure a sealed seal that can easily find a trace of fraud.

In addition, each of the slits 10 and 11 is formed so that the lower end thereof is located in the middle of the release paper 9 in the thickness direction, so that the release paper 9 is not divided by each slit and is in a single sheet state. Therefore, the release paper 9 is easily peeled off when the seal seal 5 is bonded to the object. If a laser beam is used, the slits as described above can be easily formed even when the release paper 9 is thin.
Note that it is not essential for the present invention that the lower end of each slit is located in the middle of the release paper in the thickness direction, and each slit may be provided through the release paper.

On the other hand, according to the circuit box 1 of the present embodiment, a part of the tongue-like base material 6 formed inside the slits 10 and 11 of the seal seal 5 is bent below the upper surface of the box body 4. The first concave portion 13 and the second concave portion 14 are bonded below the upper surface of the box body 4.
Therefore, even if it is going to heat the sealing seal 5 for the purpose of changing the relative relationship between the adhesive strength of the adhesive layer 8 and the breaking strength of the base material 6, the base material bonded to the first concave portion 13 and the second concave portion 14. No. 6 is difficult to directly contact equipment for heating, and it is difficult to apply heat.

  Even if an organic solvent or the like is used, it is difficult to peel off the substrate 6 bonded to the first recess 13 and the second recess 14 unless a protrusion such as an ice pick is used. Even if it is made, traces are likely to remain.

  Therefore, it is difficult to peel off from the box body 4 without impairing the appearance of the seal seal 5, and even if it can be peeled off, the trace tends to remain on the seal seal. Therefore, it is difficult to perform an illegal act such as replacing the ROM that is opened and accommodated without leaving a trace, and a circuit box in which the trace is likely to remain can be configured.

  Although one embodiment of the present invention has been described above, the technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. is there.

  6 (a) and 6 (b) are partial plan views showing seal seals 15 and 25 according to modifications of the present embodiment, respectively. In the above-described embodiment, the example in which the shape of the first slit and the second slit in a plan view is a substantially semicircular shape has been described. However, the shape of the pair of slits may be as shown in FIG. It may be formed in other arbitrary shapes such as a substantially square shape like the first slit 16 shown in a) or a substantially triangular shape like the first slit 26 shown in FIG.

In addition to the pair of slits of the first slit 26 and the second slit 27 (not shown) as in the seal seal 25 in FIG. 6B, the convex portions 28A and 29A face the other peripheral edge. Another pair of slits, that is, the third slit 28 and the fourth slit 29 that are arranged to face each other may be formed.
If it does in this way, when it is going to peel the sealing seal 25 from the edge part 30A and the edge part 30B where the convex part of the 1st slit 26 and the 2nd slit 27 is not arrange | positioned in the vicinity among the edge parts of the base material 30. The stress due to the tensile load is concentrated on both ends of the third slit 28 or the fourth slit 29. Therefore, the seal seal can be formed so that it is difficult to peel from any direction without impairing the appearance.

If there is a space, three or more pairs of slits may be formed, or the slits may not be paired, and a large number of slits may be provided radially with the convex portion outward.
And when comprising the container of this invention using these sealing seals, it is preferable to form the some recessed part corresponding to each slit, and to adhere | attach the base material inside each slit to each recessed part.

Furthermore, the end of the slit may be bent and a bent portion may be provided near the end. The bent portion may be formed by bending the end of the slit inward as in the bent portion 17 of the seal seal 15 in FIG. 6A, or the bent portion of the seal seal 25 in FIG. 6B. Like the portion 31, the slit may be formed to be bent outward. Further, like the bent portion 32, another slit 28B may be formed in a different direction from the bent portion.
If it does in this way, the way of the action of the stress in the bent part or the end part of the slit will change in a complicated manner depending on the peeling direction or the like, and prediction will be difficult. Therefore, it is possible to form a sealed seal that is more difficult to peel off without leaving a trace.

  The bent portions are not necessarily provided at both ends of the slit, and may be provided only at one end.

  Furthermore, in the seal seal of the present invention, the printing layer is not always essential and may not be provided. Further, when the printing layer is provided, it may be provided on the second surface before forming the adhesive layer, not on the first surface.

  In addition, in the above-described embodiment, an example in which the container is a circuit box has been described, but the present invention is not limited to this. The present invention can be applied to a container for any article as long as it is necessary to ensure the reliability that the article accommodated therein is not illegally replaced.

It is a perspective view which shows the seal seal and circuit box of one Embodiment of this invention. It is a top view of the seal seal. It is sectional drawing in the AA of FIG. It is sectional drawing of the box main body of the circuit box. It is sectional drawing which shows the state by which the sealing seal | sticker was adhere | attached on the box main body.
