Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a precious metal composite plate that can be possessed or stored as a souvenir or a gift, and has a decorative and asset value.

“Prior Art” Conventionally, a small gold ingot has been given a pattern on its surface by imprinting it with a mold as seen in coins and medals.

By the way, in recent years, the popularity of gold has advanced, and the unit of gold handling has become smaller and trading has been started in gram units. However, such a small amount of gold pressed into a coin or medal with a certain thickness does not look good because it is so small that it is not very effective as a souvenir or gift. was there.

Therefore, for example, a gold ingot is rolled into a thin plate shape (for example, if 1 g of gold is extended to a thickness of 15 μm, it becomes the size of a business card), and the surface of this is engraved with a pattern or letters according to the purpose. Further, by covering the thin plate with a protective film made of a transparent resin to give a composite plate having a certain thickness, it can be used as a card-shaped souvenir or gift.

"Problems to be solved by the device" By the way, it is conceivable to form the composite plate into a size of A4 size, for example, and put it in a frame or the like to further enhance the decorative and asset value. In this case, since the precious metal thin plate is very thin (about 15 μm), wrinkles are easily generated or damaged during the manufacturing process. Further, if it exceeds a certain size, there is a technical limit and manufacturing is difficult.

Further, since the above composite plate has the same color tone made of a thin plate of precious metal, it is poor in decorativeness. Furthermore, since it is sold in the naked state or put in a plastic bag etc., it is even more damaged due to surface scratches, stains, bending, etc. There is a problem that the decorative value is likely to decrease.

"Purpose of Invention" This invention was made in view of the above circumstances, and it has a relatively large area and is excellent in decorative and asset value, and it is decorative by preventing surface scratches, dirt, bending, etc. It is an object of the present invention to provide a precious metal composite plate that can maintain its value over a long period of time.

[Means for Solving the Problem] In order to achieve the above-mentioned object, the noble metal composite plate according to claim 1 of the present invention has a first protective layer made of a transparent resin on the front and back surfaces of a noble metal thin plate made of a noble metal or an alloy of noble metals. A plurality of composite plates covered with a film are arranged side by side in the horizontal direction, and a transparent decorative plate with partially opaque pictograms is overlaid on these composite plates, and the whole is made of a transparent resin second protection. It is integrally coated with a film.

The precious metal composite plate according to claim 2 is a composite plate formed by coating the front and back surfaces of a noble metal thin plate made of a noble metal or an alloy of noble metals with a transparent first protective film, and a noble metal and an alloy of noble metals with pictograms. At least one or more decorative plates are arranged side by side in the horizontal direction, and these are entirely covered with a second protective film made of a transparent resin.

[Operation] In the noble metal composite plate according to claim 1, by arranging the composite plates having the noble metal thin plates of different materials in parallel, it is possible to obtain contrast with different color tones and enhance the decorative effect. Since the pictograms applied to the transparent decorative plate with the picked up color as a background appear to float, the decorative effect can be further enhanced.

Further, by arranging the composite plates in parallel in the horizontal direction, it is possible to easily manufacture even a comparatively wide area, and furthermore, wrinkles and breakage do not occur in the precious metal thin plate.

Furthermore, since the whole is covered with the second protective film, it is possible to prevent the adhesion of dirt and the like, the occurrence of scratches and the like, the bending and the like.

Further, in the precious metal composite plate according to claim 2, since the decorative plate designed according to the purpose of use is arranged in parallel with the composite plate formed by covering the thin precious metal plate with the first protective film, the decorative effect is further enhanced. At the same time, the thin plate of precious metal can be freely made smaller to reduce the amount of gold, so a very small amount of precious metal can fully function as a souvenir or gift.

Further, since the whole is covered with the second protective film, it is possible to prevent adhesion of dirt and the like, occurrence of scratches and the like, bending and the like.

[Embodiment] An embodiment of the noble metal composite plate of the present invention will be described below with reference to FIGS. 1 to 9.
