Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a precious metal storage container, and more particularly to a precious metal storage container that can be used to hold a precious metal such as a pachinko prize gold and protect it from theft.

[0002]

[Prior art]

 Recently, noble metals such as gold have been used as prizes for pachinko machines. As a container for holding and storing the noble metal, there is a container in which an upper cover is laminated on a holding plate having a recess for storing the noble metal, and the upper cover and the holding plate are sealed with a heat-sensitive seal. However, in this case, it is easy to peel off the heat-sensitive seal with a fingertip or a knife so that it cannot be clearly recognized, replace the stored noble metal with a fake metal, and seal again. Also, a recess for storing the noble metal is provided on the surface of the noble metal holding plate, a notch groove is formed on the back surface of the noble metal holding plate, a claw is provided on the back surface, and a support base is formed on the back surface. After the noble metal is stored in the recess, the upper cover and the noble metal holding plate are fixed to each other to seal the recess, and then, to remove the noble metal from the recess, a coin such as a 10-yen coin is placed under the claw. There is a precious metal hermetic container which inserts the precious metal into the lever, makes the abutment “lever”, breaks the precious metal holding plate along the cut groove, and removes the precious metal from the recess (actually open flat 7-). 1981). However, such containers require coins to remove the precious metal from the recess.

 Hereinafter, details of the present invention will be described with reference to the drawings showing the embodiments as appropriate. FIG. 1A is a sectional view of a precious metal container before assembling showing an embodiment of the present invention, FIG. 1B is a sectional view of the noble metal container after assembling, and FIG. It is sectional drawing after removing the lower case of a container.

[0006]

【Example】

 As shown, the precious metal storage container 1 includes an upper lid 2, a middle case 3, and a lower case 4. The upper cover 2 is made of a flat plate as shown. The middle case 3 has a cavity 6 in the center of the front surface side in which the noble metal 5 can be stored. A groove 7 is provided on the back side of the middle case 3. The groove 7 is formed of, for example, a quadrangular concave portion having an appropriate width. The groove 7 is provided so as to surround the cavity 6. As shown in the drawing, the middle case 3 has a thin portion 3A formed on the outer periphery of the groove 7 with the groove 7 as a boundary, while the thin portion 3A is formed inside the groove 7. A thicker portion (thick portion) 3B is formed as compared to the thin portion (thin portion) 3A. The lower case 4 has a bottom wall 9 having a depth corresponding to the thickness of the thick portion 3B of the middle case inside the standing wall 8 around the four sides. As shown in FIG. 1 (B), the lower case 4 holds the middle case 3, protects the middle case 3 from external factors, and functions to adjust the appearance of the entire container. Keep it detachable. As shown, the storage portion 10 of the lower case 4 stores the thick portion 3 </ b> B protruding downward from the middle case 3.

In use, the noble metal 5 is housed in the cavity 6 of the middle case 3. After storage, the middle case 3 is covered with the top cover 2 and the middle case 3 and the top cover 2 are fixed. The fixing is performed by, for example, high frequency welding. By fixing the upper lid 2 and the middle case 3, the cavity 6 of the middle case 3 is sealed. The precious metal 5 is sealed in the cavity 6 and cannot be replaced with a fake. First, the lower case 4 is removed from the middle case 3 in order to take out the noble metal 5 stored as a prize from the cavity 6 of the middle case 3. The precious metal 5 may be taken out of the cavity 6 of the middle case 3 when the container becomes dirty and the precious metal needs to be transferred to a new beautiful container. As shown in FIG. 1C, when the upper lid 2 is pressed with a finger from above, the middle case 3 is broken along the groove 7 on the back side. As a result, the cavity 6 is cut off and the noble metal 5 can be taken out. As shown in FIG. 1A, when pressure is applied from above, there is a difference in the bending strength of the middle case 3 with respect to the pressure applied to the thin portion 3A, the groove portion 7, and the thick portion 3B. Due to the difference in strength, when the upper lid 2 is pressed with a finger as described above, the middle case 3 is torn along the groove 7 on the back side thereof, and only the inside of the groove 7 is cut off so that the precious metal 5 can be easily handed. Can be taken out by the force of In this case, if the thickness of the middle case 3 is the same and the thickness of the top cover 2 is the same as the thickness of the middle case 3, a groove is cut on the back side of the middle case 3 so that even if the top cover is pressed with a finger, 2 and the middle case 3 require a large force to generate a uniform torsion, and the use of the “lever” principle as in the conventional example is inevitable. May be damaged. In the present invention, a structure that produces the above-described strength difference is required, and the thick portion 3B preferably has a thickness (y) at least about three times the thickness (x) of the thin portion 3A. In the present invention, the thickness of the thick part 3B of the middle case is set to a thickness corresponding to the depth of the storage part 10 of the lower case 4, and the holding function of the middle case 3 is performed by the thick part 3B. To have it.

Although the invention made by the present inventors has been specifically described based on the embodiments, the present invention is not limited to the above embodiments, and various modifications may be made without departing from the gist of the invention. It goes without saying that it is possible.

[Effect of the invention]

 The effects obtained by typical ones of the inventions disclosed in the present application will be briefly described as follows. That is, according to the present invention, the upper lid and the middle case are fixed, the cavity portion of the middle case is sealed, the noble metal 5 is hermetically protected, and can be prevented from being replaced with a fake. Also, the middle case can be broken along the groove on the back side by simply pressing the top lid etc. with fingers from above, so the precious metal can be easily removed by hand without using coins etc. be able to. Furthermore, since the middle case is broken along the groove on the back side of the case and is destroyed and cannot be reused, even if the precious metal inside is intentionally broken by the middle case and replaced with a fake one, The replacement can be easily found by destroying the middle case.
