Description

The present invention relates to container with sealing indicia seal you seal the opening of the container the article is accommodated therein.

  Conventionally, in a game machine such as a pachinko machine or a so-called pachislot machine, a memory storing a program for controlling a winning probability, for example, a so-called ROM (ROM: read-only memory) is a box-like shape arranged in the game machine. Is housed in a circuit box. In these game machines, a seal seal is attached to the lid of the circuit box in order to prevent an illegal act of opening the circuit box and replacing the ROM stored therein with an illegal ROM having a different winning probability. The circuit box is sealed.

  In this case, when a normal seal is used as the seal seal, it is relatively easy to perform the above-described fraud by removing the seal seal without impairing the appearance. In order to make this difficult, a specially processed seal may be used as a seal 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. In general, the strength and viscosity of a resin material used as an adhesive material have a characteristic that it decreases with increasing temperature. For this reason, when the temperature of a base material and an adhesive material is raised using a heating means, adhesive strength may fall and may become smaller than the fracture strength of a sealing base material. In this case, there has been a problem that it is relatively possible to peel the patch without destroying it, and cheating is easy.

  Many of the pressure-sensitive adhesives used in the above-mentioned patch materials swell or dissolve in an organic solvent, and therefore, when an appropriate organic solvent is used, it can be peeled off without leaving a trace, and the above-described method by heating is also possible. There was also a problem that they could be used together and cheating was possible.

  In addition, examples of the device for removing the seal include a cutter and a scraper (scalpel), and the sharp tip of the device mainly along the boundary surface between the adhesive material of the seal and the adherend along the plane of the adherend. There is a known technique to remove the cleverly.

  Hereinafter, the container and the seal seal of the first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a perspective view of a circuit box (container) 1 according to the present invention with a lid 10 opened.

  The circuit box 1 is formed of a transparent and colorless material made of a resin material such as polycarbonate. In the circuit box 1, a circuit board (not shown) for controlling a game machine such as a pachinko machine is provided. In. On this circuit board, a memory storing information for determining game contents (winning probability, etc.), for example, a recording device such as a so-called ROM (ROM) is mounted. The circuit box 1 can protect the circuit board (including the memory) stored in the circuit box 1 by closing the lid 10.

  2 to 4 show a seal sticker attaching portion which is a feature of the present invention. The main body 2 of the circuit box 1 is provided with a support body 3 provided so as to jump out in parallel with the opening end face in the inner direction of the circuit box 1, and the upper surface (front surface) of the support body 3 is the opening end face. It is formed substantially in parallel. A seal table 4 is provided on the upper surface (front surface) of the support 3. A seal seal 20 having a circular shape as shown in FIGS. 1 to 4 and having an adhesive layer on the front and back is attached to the center of the seal table 4.

  As shown in FIG. 2, a recess for storing the seal table 4 protruding from the upper surface of the support 3 is provided as a seal table storage hole 11 on the back side of the lid 10. FIG. 2 shows a state immediately before the lid 10 is closed. The state after the lid 10 is closed is shown in FIG. As shown in FIG. 4, the seal table 4 enters the seal table storage hole 11 in a state after the lid 10 is closed. Here, in the state after the lid 10 is closed, the entire seal table 4 enters the seal table storage hole 11.

  In a state where the lid 10 is closed, the sealing seal 20 provided with an adhesive layer on the front and back is attached to the inner surface of the seal table storage hole 11 by the adhesive force of the adhesive layer on the seal surface (upper surface). It becomes a state. That is, the seal seal 20 of the present invention can be said to be a double-sided adhesive seal seal having an adhesive layer on both sides of the seal.

  On the other hand, the circuit box 1 which is an adherend is provided with a seal table 4 and a seal table storage hole 11 in order to take advantage of the double-sided adhesion characteristics of the seal seal, and the adhesive layer on the back surface of the seal seal 20 The adhesive layer on the surface of the seal seal 20 is adhered to the back surface of the seal table storage hole 11 and adhered to each other by its own adhesive force.

  The back surface of the seal table storage hole 11 is a transparent portion and position where the seal surface of the seal seal 20 can be seen best when the lid 10 is viewed from above, and further, the back surface portion of the seal table storage hole 11 Is the portion of the lid 10 where the plate thickness is the thinnest, so that the transparency is increased. For this reason, the portion of the lid 10 located on the inner surface of the seal table storage hole 11 is used as the area of the seal visual recognition window 13. The seal visual recognition window 13 also serves as a confirmation window for examining whether or not there is a trace peeled off on the seal seal 20 when the container and the seal seal of the present invention are actually applied. If the mechanical strength allows from the visibility of the seal and the transparency of the lid 10, the thickness of the window portion should be as thin as possible as compared with the other portions of the lid 10.

  In addition, the shape of the seal table 4 and the seal table storage hole 11 is not limited to a circular shape in plan view in the present embodiment, and may be another shape such as an ellipse or a rectangle.

  As shown in FIG. 2, a packing 6 is provided on the outer peripheral surface of the protruding portion of the seal table 4 for the reason described later. The cylindrical side surface of the cylindrical seal table 4 is provided with a fine groove so as to go around the side surface. By fitting a part of the inside of the packing 6 into this groove, the packing 6 itself can be fixed. The packing 6 is prevented from shifting when the lid 10 is opened and closed. The packing 6 may be a packing made of a rubber material also called an O-ring.

  As shown in FIG. 3, the seal table 4 has a circular shape when viewed from the upper surface (plan view). On the other hand, the seal table storage hole 11 for storing the seal table 4 is slightly viewed from the upper surface (plan view). The position may be elliptical or eccentric. As a result, the packing 6 does not contact the inner peripheral surface of the seal table storage hole 11 with uniform pressure over the entire periphery. That is, although it is an airtight space between the upper surface of the seal table 4 and the inner surface of the seal table storage hole 11, a part of the packing 6 is artificially weakly airtight for reasons described later. It has been. Moreover, you may form a part of packing 6 itself as a location where airtightness is weak.

  Fixing holes 12 are provided in portions of the support 3 and the lid 10 corresponding to each other. The fixing hole 12 is a hole for tightly fixing the support 3 and the lid 10 with a fixing tool such as a screw or a bolt.

Next, the sealing seal 20 will be described with reference to FIGS.
The seal seal 20 includes a base material 21, and an information layer 22 is formed on the surface of the base material 21 in the surface direction (upward direction). On the upper surface of the information layer 22, a release layer 23 is formed by patterning. Further, a first adhesive layer 25 is formed on the upper surface of the release layer 23 and the upper surface of the information layer 22 without the release layer 23. The adhesive layer 25 here is formed over the entire area of the information layer 22. Further, since the release layer 23 is formed in a pattern, the information layer 22 is in a state where a portion covered by the release layer 23 and a portion directly covered by the adhesive layer 25 are partially and dispersed. Yes.

  On the other hand, another release layer 24 is provided on the back surface (downward) surface of the base material 21. The region of the release layer 24 and the region of the release layer 23 are when the sealing seal 20 is viewed from the top. Are patterned so as not to overlap each other. However, the region of the release layer 24 and the region of the release layer 23 may partially overlap or partially intersect when the sealing seal 20 is viewed from the upper surface. Here, the pattern shape of the release layer 23 or the release layer 24 includes a pattern shape of a partial pattern such as a band shape, a dot shape, or a lattice shape. The pattern may be dispersed or continuous.

  In addition, a second adhesive layer 26 is formed on the lower surface of the back surface of the base material 21 provided with the release layer 24 and on the lower surface of the base material 21 without the release layer 24. Here, the adhesive layer 26 is formed over the entire area of the lower surface of the substrate 21.

  The base material 21 is preferably made of a brittle material that is plastically deformed and further ruptured and broken, and more preferably broken by a tensile load smaller than the adhesive strength of the adhesive layer 25 and the adhesive layer 26. Examples of the material of the base material 21 include synthetic resin films such as brittle vinyl chloride and brittle polyester which are made brittle by mixing an appropriate amount of a plasticizer such as kaolin and calcium carbonate, or cellulose acetate, low density polyethylene, polystyrene. And a film formed of a highly crystalline plastic material such as polyphenylene sulfide by solution film formation. As other materials, a so-called UV (ultraviolet ray) curable synthetic resin or a UV curable synthetic resin in which an appropriate amount of powders such as kaolin and calcium carbonate are mixed, and the resin thin film is cured and dried by UV irradiation to form a film. A film etc. are mentioned.

  The information layer 22 is an offset print, silk screen print, or any arbitrary design formed by combining geometric shapes such as characters, images, and lattices alone or in combination with various printing inks including known security inks. It can be formed by a printing method such as gravure printing or flexographic printing. Other than printing, a known security device such as OVD (Optical Variable Device) may be formed. Here, OVD is a general term for a multilayer thin film that changes color depending on the viewing angle by overlapping holograms and diffraction gratings that can express stereoscopic images and special decorative images using light interference, and thin films with different optical characteristics. is there.

  Even if the circuit box 1 is illegally opened and the sealing seal is broken, the sealing seal itself is forged, and the fraudulent act of returning the forged sealing seal back into the circuit box 1 and leaving no trace of opening is also sufficient. Therefore, it is desirable that the information formed in the information layer 22 cannot be easily forged.

  As a material for the release layer 23 and the release layer 24, an appropriate release agent such as silicon is used.

  The adhesive layer 25 and the adhesive layer 26 are layers for adhering to the circuit box 1 to be sealed by the seal seal 20, and the material of this layer is an acrylic adhesive material, a polyester adhesive material, a urethane adhesive material Various known adhesive materials such as these can be used.

  The adhesive layer 25 and the adhesive layer 26 can form these pressure-sensitive adhesive materials on the front and back surfaces of the base material 21 by the above-described various printing methods, coating methods, and the like. It can be appropriately set within a range of about 20 μm.

  Next, when the lid 10 is opened in a state where the seal seal 20 is attached to the seal table 4 and the seal table storage hole 11, particularly when the upper and lower adhesive surfaces are separated in parallel to the base material 21. The resulting state is shown in FIG. That is, since there is no adhesive force of the adhesive layer at the boundary surface between the release layer 23, the release layer 24 and the adhesive layer 25, and the adhesive layer 26, a phenomenon of peeling at the boundary surface occurs. Further, since the base material 21 is a brittle material that is broken and broken as described above, the longitudinal tearing occurs between the release layer 23 and the release layer 24 as shown in FIG.

  When the lid 10 is opened, the information layer 22 is also torn due to these phenomena. Therefore, even if the lid 10 is closed again, the information layer 22 that has been torn once does not return to its original position at the portion where the information layer 22 is formed by printing, and the portion where the OVD is formed. Since the smoothness does not return to the original state, these changes of the information layer 22 can be visually confirmed from the seal visual recognition window 13 as an opened trace.

  Since the thicknesses of the adhesive layer 25 and the adhesive layer 26 are about 1 to 20 μm as described above, depending on the viscosity (viscosity) of the adhesive layer to be used, the top surface of the seal table 4 and the back surface of the seal table storage hole 11 The substrate 21 is surely torn by leaving the distance of 50 μm or more, and as a result, an unsealed trace remains in the information layer 22.

  An illegal act may be considered in which the circuit box 1 itself is immersed in a liquid of an organic solvent for a long time, and the adhesive layer of the seal seal 20 is dissolved and peeled off by the penetration force of the organic solvent. However, in the state where the lid 10 is closed, in the space between the upper surface of the seal table 4 and the inner surface of the seal table storage hole 11, an airtight state is caused by the action of the packing 6 provided on the side surface of the seal table 4. Made. This airtight state can prevent the organic solvent from penetrating into the adhesive layer of the seal seal 20.

  In addition, even if the lid 10 is opened little by little for the purpose of dissolving the adhesive layer of the sealing seal 20 while being soaked, the packing 6 provided on the side surface of the seal table 4 is provided with the seal table storage hole. By sliding the inner side surface of 11, the airtight state is maintained, and as a result, penetration of the organic solvent can be prevented. Even if the lid 10 is opened little by little, the base material 21 is torn when the distance between the upper surface of the seal table 4 and the inner surface of the seal table storage hole 11 is 50 μm or more as described above. There are very few.

  Next, the circuit box 1 according to the second embodiment will be described with reference to FIGS.

  A plurality of protrusions 30 are provided on the back surface of the seal visual recognition window 13, that is, the inner surface of the seal table storage hole 11 so as to cooperate with the pattern shape of the release layer 23 as shown in FIG. 7.

  On the other hand, a plurality of protrusions 31 are similarly provided on the upper surface of the seal table 4 so as to cooperate with the pattern of the release layer 24. In addition, the protrusion 30 and the protrusion 31 are provided at the same location as the above-described tearing portion of the base material 21.

  In the plan view seen from the upper surface, the protrusion 31 is formed in a continuous pattern in a lattice shape on the upper surface of the seal table 4 as shown in FIG. The protrusion 30 is provided by modeling. However, some portions of the protrusion 30 and the protrusion 31 have no continuity for the reason described later. The protrusion 30 and the protrusion 31 have sharp tips.

  Further, in the protrusion 31, the protrusion tip having a sharp tip pierces the base material 21 made of a brittle material, and cracks and fractures occur in a part near the protrusion tip. It is happening to the whole. As described above, the lid 10 and the support 3 are tightly fixed by being fastened by a fixing tool such as a screw or a bolt inserted into the fixing screw hole 12, and at the same time, the tip of the protrusion 31 pierces the base material 21.

  Although FIG. 8 shows the modeling viewed from the upper surface of the protrusion 30 and the protrusion 31, the modeling is not limited to the lattice shape of the present embodiment.

  FIG. 9 is a view in which a security layer 14 such as OVD is added to the upper surface of the seal visual recognition window 13 for the reason described later. The security layer 14 is a layer in which a transparent hologram or the like is thin (100 μm or less) and has a transparent OVD on the upper surface of the seal visual recognition window 13 by a method such as thermal transfer.

  An airtight space between the upper surface of the seal table 4 and the inner surface of the seal table storage hole 11 is formed by making a thin hole in a part of the seal visual recognition window 13 and applying an organic solvent under pressure from the hole. An illegal act of filling the organic solvent with the organic solvent and dissolving and peeling off the adhesive layer of the seal seal 20 by the penetration force of the organic solvent is also conceivable. The narrow hole opened in the seal visual recognition window 13 can be skillfully filled with a transparent resin or the like after opening so that it cannot be seen at a glance.

  In the second embodiment, countermeasures against the above fraud are added to the first embodiment.

  When an organic solvent is injected by applying pressure from a narrow hole formed in a part of the seal visual recognition window 13, the organic solvent advances in the direction of the portion where the continuity of the protrusion 30 and the protrusion 31 is cut off, The packing 6 reaches the packing 6 and fills with the organic solvent. However, as described above, a portion of the packing 6 is weak against the internal pressure, so that the organic solvent leaks from the portion, thereby sealing the packing 6. The organic solvent is not filled in the airtight space between the upper surface of the table 4 and the inner surface of the seal table storage hole 11.

  On the other hand, in the section where the continuity of the protrusion 30 and the protrusion 31 is not cut (the square portion in the lattice shape in FIG. 8 is referred to as a section), they become partition walls and the penetration of the organic solvent is small.

  In the information layer 22 where the organic solvent has progressed, if it is a printed layer of a geometric shape such as a character, image, or lattice printed with printing ink, the printing ink is organic solvent. In response to this, bleeding or the like occurs, leaving a trace of fraud.

  The thin hole opened in the seal viewing window 13 can be cleverly filled with a transparent resin after opening, so that it cannot be seen at first glance. However, a security layer 14 such as OVD is formed on the upper surface of the seal viewing window 13. The following deterrent effects can be expected.

  In the OVD having a thin layer of a transparent hologram or the like (100 μm or less) and transparency, it is very difficult to repair a portion (a portion having a hole) because of its fine pattern due to its structure. In terms of leaving no trace of opening, it is a significant deterrent effect.

  Instead of the security layer 14, the same fine pattern may be provided directly on the upper surface of the seal visual recognition window 13 with a laser beam or the like, and partial repair is very difficult like the security layer 14.

  From the above, the container and the seal seal of the present invention are in a state where a double-sided adhesive seal seal provided with an adhesive layer on the front and back of the seal is affixed inside the container. A sharp tip or the like cannot be used to advance the sharp tip along the interface between the adhesive material of the seal and the adherend, and the substrate cannot be peeled off in an attempt to peel off the seal seal. Therefore, it is difficult to peel off from the circuit box (container) without impairing the appearance of the seal seal, 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.

  The embodiments of the present invention have been described above, but the technical scope of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. It is. Each embodiment can be combined with the other embodiments.

  In the above-described embodiment, the information layer 22 is formed on the base material 21. However, the release layer 23 may be provided on the base material 21 and the information layer 22 may be provided thereon. The base material 21 may not be a brittle material. When there is an illegal peeling action as described above, there is no adhesive force at the boundary surface between the release layer 23 and the base material 21, so that a phenomenon that peels off at the boundary surface occurs and the information layer 22 is torn as a result. . Furthermore, an antenna pattern printed with RFID silver paste ink can be provided on the lower surface of the information layer 22. The antenna pattern is concealed by the information layer 22, and when there is an illegal peeling action, the antenna pattern is disconnected together with the information layer 22, and as a result, the communication function is also lost.

In the above layer configuration, the front and back may be reversed, or the information layer 22 may be on both sides.
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. In addition, 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.
