BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case for storing a noble metal such as gold so that it can be seen from the outside.

[0002]

2. Description of the Related Art As a case for storing a noble metal such as gold, it is necessary to be able to confirm the noble metal from the outside when handling the noble metal together with the case. Also, if the precious metal in the case has been replaced with a counterfeit product, that fact must be made readily apparent.

Conventionally, as this kind of case, for example,
There is one disclosed in Utility Model Registration No. 2590558. The above publication discloses a case including a recess for storing a noble metal in a case for storing a noble metal, a cut groove surrounding the recess, and a claw provided integrally with a bottom surface of the recess. In such a case, the pawl must be raised when the precious metal is taken out, and when the pawl is raised, the case is broken from the cut groove, and the case cannot be reused, thereby preventing forgery of the case. Is done.

[0004] However, the case disclosed in the above publication requires the provision of the pawl. When such a pawl is provided, the pawl not only extends in the thickness direction of the case but also in the direction perpendicular thereto. Protruding parts must be provided. However, since such a case is molded using a mold, when the case disclosed in the above publication is molded using a mold, there is an inconvenience that the shape of the mold is complicated.

[0005]

SUMMARY OF THE INVENTION The present invention aims at improving a precious metal storage case. More specifically, in order to solve the above-mentioned inconvenience, it is possible to mold the case with a mold having a simple shape, and
An object of the present invention is to provide a noble metal storage case in which the case cannot be reused after the noble metal stored inside is taken out.

[0006]

To achieve the above object, a precious metal storage case according to the present invention is a storage case for storing a precious metal so that it can be seen from the outside, and the storage case is formed of a plate-like member. A flat cylindrical front case having a peripheral portion protruding rearward and an open back surface; and a substantially plate-shaped rear case fixed to a peripheral portion of the front case. The lower back case is firmly fixed to the front case as compared with the upper back case, and the upper back case and the front case face each other. Is provided with an opening.

In the precious metal storage case of the present invention, the back case is divided into an upper part and a lower part by the breaking groove.
The lower part is more firmly fixed to the front case than the upper part. Further, the opening is provided in an upper portion where the fixing force with the front case is weak. When removing the noble metal from the noble metal storage case of the present invention, it is necessary to separate the front case and the back case, but when the front case and the back case are separated from the opening provided above. The upper part having a weak fixing force is easily separated, while the lower part having a strong fixing force is hard to be separated. Therefore, stress concentrates on the breaking groove which bisects the back case vertically, and the breaking groove is broken. This makes it impossible to reuse the case, thereby preventing forgery of the case. Further, since the breaking groove is provided on the surface of the back case, when the back case is molded by a mold, the structure of the mold is also simple.

In the precious metal storage case according to the present invention, the storage case includes an inner case stored between the front case and the back case, and the surface of the inner case stores the noble metal. A storage recess is provided, wherein the noble metal is stored between the storage recess and the inner surface of the front case, the inner case is fixed to a peripheral portion of the front case, and front and back near the storage recess of the inner case. A second through hole is provided on the back surface of the inner case from the through hole or the vicinity thereof toward the storage recess.
Is preferably provided.

The storage case includes the inner case, and since the front case and the inner case are fixed at a peripheral portion, the front case and the inner case are separated to take out the noble metal. There is a need to. In this case, when any member (for example, a coin or a flathead screwdriver) is inserted into the through hole and the inner case is pryed open, the second break groove provided between the through hole and the storage recess is formed. The stress is concentrated and the second
The inner case is ruptured from the rupture groove. This makes it impossible to reuse the case, thereby preventing forgery of the case.

In the precious metal storage case according to the present invention, the storage recess is provided with a second through-hole extending in a direction substantially perpendicular to the second break groove, and the second case is provided in the inner case. It is preferable that a third break groove extending from the through hole is provided.

When an attempt is made to take out the noble metal by inserting some member from the through hole, first, the second breaking groove is broken to generate a crack, and the crack reaches the second through hole. Next, since stress is applied to the third breaking groove extending from the second through hole, the inner case is broken along the second breaking hole and the third breaking groove. This makes it impossible to reuse the case, thereby preventing forgery of the case. Further, the second breaking groove,
Since the second through hole and the third break groove are provided so as to penetrate the surface or the front and back of the inner case, when the back case is molded by a mold, the structure of the mold is also simple. Becomes

Further, in the precious metal storage case of the present invention, an easily breakable hologram seal is stuck on a surface of the inner case including at least a surface side of the second break groove or the third break groove. Is preferred. When the hologram seal is stuck to the inner case, the hologram seal is also broken when the second break groove or the third break groove is broken. Since the hologram seal broken in this way is difficult to restore so that the broken portion is inconspicuous, when the broken inner case is reused, it was once broken by the broken hologram seal. Is easily recognized,
Counterfeiting of the case is prevented.

As shown in FIG. 7, a hologram seal 17 is stuck by thermal transfer. The hologram seal 17 is made of a material which has no elasticity and is easily broken.
The surface of the surface plate 5a is easily broken when a crack is formed in the surface of the surface plate 5a because the surface of the surface plate 5a is integrated by thermal transfer.
In FIG. 1, a hatched portion on the rear end surface of the side plate 5 b is a welded portion 8 welded to the back case 4. In the present embodiment, the entire rear end face of the side plate 5b is welded to the lower side of the first breaking groove 9 of the back side case 4, and the upper side is not welded. In addition,
Ribs 18 extending from the front plate 5a toward the back surface
The storage recess reinforcing portion 19 is formed so as to come into contact with the surface of the back case 4 when the inner case 5 is welded to the back case 4.

The precious metal storage case 1 having the above configuration is
As shown in FIGS. 1 and 3, the inner case 5 is engaged with the rib 11 of the back case 4 and the inner case 5 is attached to the front case 3.
Are fitted. In this state, the lower part of the side plate 5b of the inner case 5 is welded to the back case 4 and the lower part and a part of the upper part of the side plate 3b of the front case 3 are welded. The metal bullion 2 is stored in the storage recess 12 of the inner case 5, and is held between the storage recess 12 and the support portion 7 provided in the front case 3. In this manner, when the front case 3 and the inner case 5 are welded to the back case 4, since each case is formed of a transparent synthetic resin, the metal bullion 2 and the hologram seal 17 must be checked from the outside. Can be. The gold bullion 2 is stored in the storage recess 12.
And is supported by the support portion 7, there is no risk of shifting to a location other than the storage recess 12. Note that, even when a force is applied from the surface of the front case 3 while the precious metal storage case 1 of the present embodiment is being carried, the ribs 18 and the storage recess reinforcing portions 19 provided on the inner case 5 are fixed to the rear case. Since the inner case 5 is in contact with the surface of the inner case 4, the bending of the inner case 5 is suppressed, so that the inner case 5 is not damaged.

When the internal gold bullion 2 is taken out of the noble metal storage case 1 in which the gold bullion 2 is stored, the following procedure is performed. First, a coin or the like is inserted into the opening 6 and a force is applied in a direction to separate the front case 3 and the back case 4. The portion of the welding surface of the front case 3 and the back case 4 where the opening 6 is provided, that is, the portion above the first breaking groove 9 of the back case 4 in FIG. Therefore, the front case 3 and the rear case 4 can be easily separated. On the other hand, in FIG. 1, the portion of the back case 4 below the first breaking groove 9 is welded to all the portions facing each other, so it is difficult to separate the front case 3 and the back case 4. is there. Therefore, when the front case 3 and the back case 4 are separated from the opening 6 in FIG. 1, a load is applied to the center of both cases.

Here, since the front case 3 is provided with the side plate 3b, the bending strength is high. On the other hand, the ribs 11 are provided on the back case 4, but the ribs 11 are not provided on the left and right sides of the first break groove 9, so that stress concentrates on the first break grooves 9 of the back case 4. Thereby, the first breaking groove 9 is broken, and the upper part of the back case 4 is separated. In this state, the front case 3 and the inner case 5 are fixed to the lower part of the back case 4.

Next, a member such as a coin or a flathead screwdriver is inserted into the first through hole 13 so as to separate the inner case 5 from the front case 3 so as to separate the inner case 5 from this state. Then, stress concentrates on the second break groove 14 provided in the vicinity of the first through hole 13, and the inner case 5 is broken from the second break groove 14. Also, the second breaking groove 1
When the inner case 5 is broken from 4, the breaking line reaches the second through hole 15 provided in the storage recess 12, and stress is also generated in the third breaking grooves 16 provided on the left and right sides.
As a result, the inner case 5 is broken in the direction of the second through hole 15 and the third breaking groove 16, so that the gold bullion 2 stored in the storage recess 12 can be taken out.

The precious metal storage case 1 of the present embodiment can take out the gold bullion 2 stored therein as described above. It is broken from 9. Also, the inner case 5
The second breaking groove 14 and the third breaking groove 16 are also broken. As described above, the precious metal storage case 1 according to the present embodiment has the rear case 4 when the gold bullion 2 stored therein is taken out.
In addition, since the inner case 5 is damaged, the gold bullion 2 cannot be stored inside again. Therefore, an illegal act such as storing a counterfeit product instead of the gold bullion 2 can be prevented. A hologram seal 17 is adhered to the surface of the inner case 5, and when the second break groove 14 and the third break groove 16 are broken, the hologram seal 17 is also broken. Since the hologram seal 17 cannot be repaired once broken, this hologram seal 1
7 can also prevent unauthorized acts. Further, in this embodiment, since each case is formed of a transparent synthetic resin, the first break groove 9 and the second break groove 1 are formed.
When the fourth or third breaking groove 16 is broken, the periphery thereof becomes cloudy. For this reason, it is more difficult to repair the back case 4 and the inner case 5 that have been damaged once.

In the above-described embodiment, the upper part of the first break groove 9 in FIG. 1 is welded to the front case 3 and the back case 4 at four welding portions 8. When the rear case 4 is formed of a member having a certain strength, the upper case does not have to be welded to the upper case because the case is not easily separated except when the two cases are to be separated. In addition, since the lower portion of the first breaking groove 9 only needs to be fixed more firmly than the upper portion thereof, it is not necessary to fix all of the facing portions of both cases. In the above embodiment, the respective cases are fixed by welding, but may be bonded by using an adhesive. Further, in the above-described embodiment, the precious metal has been described by taking the gold bullion 2 as an example. However, the present invention is not limited to this, and it is obvious that platinum, silver, or imitations thereof are also included in the present invention. is there.
