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 seal is attached to the lid of the circuit box and sealed in order to prevent an illegal act of opening the circuit box and replacing the stored ROM with an illegal ROM having a different winning probability.

  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 resin materials used as pressure-sensitive adhesives decrease as the temperature rises.

Hereinafter, a sealing seal and a container according to an embodiment of the present invention will be described with reference to FIGS. 1 to 14.
FIG. 1 shows a perspective view of the circuit box (container) 1 of the present invention with the lid 3 opened.
The circuit box 1 includes a circuit board 2 for controlling a game machine such as a pachinko machine, and a ROM (not shown) for determining game contents (winning probability, etc.) is mounted on the circuit board. Has been. The circuit board 2 can be protected by closing the lid 3.
The material of the circuit box (container) 1 is preferably a plastic resin that is transparent and hardly cracked, and examples thereof include vinyl chloride resin, polyester resin, styrene resin, ABS resin, and polypropylene resin.

FIG. 2 shows a perspective view with the lid 3 closed.
In order to prevent the lid 3 from being illegally opened, the sealing seal 4 of the present invention is applied.

FIG. 3 is a cross-sectional view of the seal seal 4.
As shown in FIG. 3, the seal 4 includes a sheet-like base material 5, a printing layer 6 provided on the upper surface of the base material 5, and an adhesive layer 7 provided on the lower surface of the base material 6. It is configured.

The substrate 5 is preferably made of a brittle material that is plastically deformed and further broken or broken, and more preferably broken by a tensile load smaller than the adhesive strength of the adhesive layer 7.
Examples of the material include synthetic resin films such as brittle vinyl chloride and brittle polyester that are made brittle by mixing a suitable amount of fillers such as kaolin and calcium carbonate, or cellulose acetate, low density polyethylene, polystyrene, polyphenylene sulfide, etc. The film etc. which formed this highly crystalline plastic material by solution film-forming are mention | raise | lifted.
Other materials include UV curable synthetic resin or UV curable synthetic resin mixed with an appropriate amount of powders such as kaolin and calcium carbonate, and a film obtained by curing and drying the resin thin film by UV irradiation. .

  The printing layer 6 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 6 changes its appearance due to distortion or the like when an external force is applied to the substrate 5, so that it becomes a trace of fraud and the like, and has a function of improving its visibility.

The adhesive layer 7 is for adhering the seal seal 4 to the box body 1 to be sealed. As a material of the adhesive layer 7, 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 7 can form these pressure-sensitive adhesive materials on the lower surface of the base material 5 by the above-described various printing methods and coating methods, and the thickness is appropriately in the range of about 1 to 20 μm as necessary. Can be set.

FIG. 4 is an external view of the seal sticking device 8.
The sticking head 9 moves up and down by the vertical mechanism of the apparatus, and can apply a load to the seal seal when the seal sticker is stuck. Two types of heads, a perforated head 9A and a heating head 9B, which will be described later, are attached to the pasting head 9.

FIG. 5 is a cross-sectional view showing the positional relationship between the sticking head 9 of the sticker sticking device 8, the seal sticker 4, and the sticker sticking part 10 of the box body 1.
As shown in FIG. 5, with the seal sticker 4 temporarily attached to the sticker attaching portion 10 of the box body 1, the box body 1 is placed under the sticking head 9 in the raised position, and the vertical mechanism is moved. After the sticking head 9 is lowered and reaches the seal seal 4, the pressure is applied to the seal seal 4.

FIG. 6 is an enlarged cross-sectional view of the seal attaching portion 10 of the box body 1, and FIG. 7 is an enlarged view of the seal attaching portion 10 as viewed from above.
A plurality of projections 1A having a sharp tip as shown in FIG. 6 are formed on the surface of the sticking portion 10 and the projection 1A has a circular shape as shown in FIG. It is placed at regular intervals vertically and horizontally.

FIG. 8 shows an enlarged view of the broken line ellipse A of FIG.
This is a state (temporary placement) in which the seal seal 4 is placed on the protruding portion 1A of the seal attaching portion 10. Note that the print layer 6 is omitted from FIGS. 8 to 14 including this figure.

Next, a perforated head 9A as shown in FIG. 9 is attached to the seal attaching device 9, and the head is lowered. As shown in the figure, the hole of the perforated head 9A has a shape through which the protruding portion 1A passes, and by lowering the perforated head 9A, the sharp tip of the protruding portion 1A is the base of the sealing seal 4 made of a brittle material. At the same time, the adhesive layer 7 reaches the bottom of the seal application part 10 and is pressed to attach the seal seal 4.
A state in which the perforated head 9A is raised is shown in FIG. When the base material 5 is plastically deformed, there is no gap around the protrusion 1A. Thus, if a tensile load is applied to the base material 5 in an attempt to illegally peel off the seal, the base material 5 is plastically deformed and a gap is formed around the protrusion 1A. Makes it easy to find the traces.

Next, a heating head 9B as shown in FIG. 11 is attached to the seal attaching device 9, and the head is lowered. The heating head 9B is a head provided with a heat generating part that can be heated up to the melting temperature of the material constituting the box body 1, and the head surface has a planar shape as shown in the figure.
By lowering the heating head 9B heated to the above melting temperature, it is applied to the tip of the protrusion 1A, and further, the protrusion 1A is pressed and lowered to the bite position into the sealing seal 4 as shown in the figure while being thermally melted. Let A state in which the heating head 9B is raised is shown in FIG. The tip of the projection 1A has a wedge shape, which means that the seal seal 4 cannot be removed as it is, that is, the seal seal 4 is sealed.

  An illegal act may be considered in which the lower part of the protrusion 1A deformed by heat melting is cut with a nipper or a cutter, the sealing seal 4 is peeled off, and then the head of the cut protrusion 1A is adhered and restored with an adhesive or the like. . As countermeasures against this act, as shown in FIG. 14, it is possible to make the fraudulent act difficult by providing optical reflectors 11 on the flat portions of all the protrusions 1A. Since the circuit box (container) is made of a plastic resin that is difficult to break, it is not possible to easily break the head of the projection 1A.

The reflector 11 may be anything as long as it is optically reflective, and examples thereof include metallic pigment ink and a metal vapor deposition film.
Next, how to use the reflector 11, the determination method, and the effect will be described. When a light source such as an electric light is reflected by a plurality of reflectors 11 provided on the flat surface of the protrusion 1A, the parallelism of each surface can be determined with high accuracy and instantaneously. This is a determination method using the characteristics of the human eye. When the head portion of the protruding portion 1A cut as described above is bonded and restored with an adhesive or the like, the flat portion of the protruding portion 1A is forced to be restored with high accuracy, and all the cut pieces are cut off. I think it is very difficult to perform such work on the head.

  If the seal is to be peeled off, the seal application part 10 has a protrusion 1A and is not flat like the conventional application surface of the adherend, so use a cutter, scraper, etc. Thus, as in the prior art, it has a structure in which a sharp tip cannot be advanced along the boundary surface between the adhesive material of the seal and the adherend, and even if it can be peeled off, the trace tends to remain on the seal.

  Therefore, it is difficult to peel off from the box body 1 without impairing the appearance of the seal seal 4, and even if it can be peeled off, the trace is likely 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.

  In this description, the shape of the protruding portion 1A is as shown in FIGS. 6 and 7. However, any shape can be used as long as the protruding portion has a sharp tip and can penetrate and penetrate the base material 5. It does not matter. Although an arrangement as viewed from above, has been equally spaced arranged vertically and horizontally as shown in FIG. 7 in the present description, any quantity, including the quantity thereof, it may be disposed.

  The position of the deformed head portion of the protrusion 1A due to heat melting may be a position away from the label as shown in FIG. 13, and in this case, the base material 5 is plastically deformed to surround the protrusion 1A. It becomes easier to see the state where there is no gap, and it becomes easier to find traces of unauthorized peeling.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and can be implemented in various forms without departing from the spirit of the present invention.

  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.
