Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a thin precious metal composite plate with a pictogram that can be easily carried or stored as a souvenir or a gift and that has a decorative and property 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 a gift.

"Problems to be solved by the invention" However, the composite plate is sold in a bare state or put in a vinyl bag or the like, and due to dirt or bending on the surface for this purpose, it is used as a souvenir or a gift. This has caused a decrease in decorative value.

Although the bending of the composite plate can be prevented to some extent by increasing the thickness of the precious metal thin plate, this makes the price of the composite plate so high that it cannot be easily used as a souvenir or a gift. In particular, when the above composite plate is used as a bookmark or the like, it is necessary to make it inexpensive and to make it thin and difficult to bend.

"Purpose of Invention" This invention was made in view of the above circumstances, and it can be easily used as a souvenir or a gift as well as maintain its decorative value for a long time. It is an object of the present invention to provide a thin precious metal composite plate with a pictogram that is thin and hard to bend even if it is thin.

[Means for Solving the Problem] In order to achieve the above object, the thin precious metal composite plate with pictograms of the present invention is a first protective film made of a transparent resin on the front and back surfaces of a precious metal thin plate made of a precious metal or an alloy of precious metals. The surface of the composite plate covered with is overlaid with a transparent decorative plate with partially opaque pictograms, and the back side is overlaid with a reinforcing plate that is harder than the above-mentioned thin sheet of precious metal, and these are all made of transparent resin. It is covered with a second protective film.

Depending on the purpose of use, the composite plate and the reinforcing plate may have the same size, or the reinforcing plate may be larger than the composite plate, and both may have different shapes.

[Operation] In the thin precious metal composite plate with pictograms of the present invention, the composite plate obtained by coating the front and back surfaces of the precious metal thin plate with the first protective film made of transparent resin is reinforced by the reinforcing plate and the transparent decorative plate. Therefore, it is possible to prevent bending when handling.

In addition, since the whole is covered with the second protective film, it is possible to prevent the adhesion of dirt and the like and maintain the decorative and property value for a long time.

Furthermore, if the composite plate is made appropriately smaller than the reinforcing plate, the amount of precious metal can be easily changed depending on the purpose of use, and it can be made inexpensive, and it is thin and difficult to bend such as bookmarks, and it is inexpensive. Is suitable for those requiring.
