Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention can be easily used as a souvenir or a gift, and has a decorative value.
The present invention relates to a thin-walled precious metal composite plate with a pictogram that is mainly made of precious metal such as platinum.

[Prior Art] Conventionally, small gold nuggets have been provided with a pattern on the surface by engraving using a die as seen in coins and medals.

By the way, in recent years, gold has become popular, and the handling unit of gold has become smaller and the gold has been traded in 1g units. However, such a small amount of gold pressed and molded as a coin or medal while having a certain thickness does not look good because of its very small shape, and is less effective as a souvenir or gift. was there.

Therefore, it is conceivable that an ingot is rolled into a very thin plate shape, the surface of which is marked by engraving or the like, and a pattern or a character according to the purpose is attached. In this case, for example, if 1 g of gold is extended to a thickness of 20 μm or less, the size becomes about the size of a business card, and the appearance becomes sufficiently large. And
By applying a protective film to this with a transparent resin or the like, it is possible to prevent deformation and adhesion of dirt, and ensure durability.

[Problems to be Solved by the Invention] However, in the conventional techniques as described above,
Since engraving is done using a mold on a very thin plate, the marking location becomes thin and the mark can be seen through on the back, and irregularities also appear on the back, so marking was possible only on one side. Therefore, while coins and medals can be given different pictograms on the front and back sides, they do not look good and have a low commercial value.

[Means for Solving the Problems] In order to solve the above problems, the present invention relates to a composite plate in which a transparent protective film is adhered to a thin plate made of a noble metal or an alloy of noble metals and marking is performed by engraving. , And a transparent decorative plate having a partially opaque pictogram is overlapped, and both are covered with a transparent protective film.

[Operation] In such a thin precious metal composite plate with pictograms,
Since a transparent protective film is attached to the noble metal thin plate and then the marking is performed on the thin metal plate, the thin plate can be prevented from being partially removed by punching and wrinkles caused by the marking. Then, the composite plate with such marking is
By overlapping with a transparent decorative plate with a partially opaque pictogram, the pictogram on the decorative plate appears to float up against the background of the precious metal from the viewpoint of the decorative plate,
Also, when viewed from the composite plate side, the pictograms marked on the precious metal thin plate can be seen, and a thin precious metal composite plate having pictograms having different color tones and contrasts on both sides of the plate can be obtained.

Embodiments Embodiments of the present invention will be described below with reference to the drawings.

In Fig. 1, reference numeral 1 indicates a thin gold plate, which has a thickness of 15μ after repeated rolling of a bulk material having a purity of 99.99% or more.
After finishing to m and cutting into a business card size, both sides were laminated and covered with a first protective film 2 made of a transparent resin to obtain a composite plate 3. In addition to this, the characters as shown in FIG.
Marking 4 such as symbols and patterns was applied. In this case, the gold thin plate 1 and the first protective film 2 are further thinned at the portion stamped by the stamping, whereby the marking 4
However, since the resin film is less likely to be plastically deformed than gold and is less likely to be thinned, it is less likely that a hole will be formed in the marking portion. Therefore, a part separated from the surroundings during marking does not fall off, and marking by marking can be stably performed. If you use an appropriate punch, etc., you can engrave any figure, pattern, character,
It is easy, quick, and inexpensive to attach portraits and certification marks to thin plates. The content displayed on the precious metal sheet 1 is not particularly limited, but it is appropriate to indicate the material, quality, weight, etc. of the precious metal sheet itself as a part of the display. It can be attached in advance separately from the mark attached to.

FIG. 2 shows a decorative plate 5 made of, for example, a resin such as acrylic or a material such as glass, on one surface or both surfaces of which a pictogram 6 made of an opaque portion is provided. This material does not necessarily have to be highly rigid, and may be flexible such as vinyl, and its thickness is set appropriately. In addition, for the opaque portion, an appropriate method such as application of a paint, relief engraving, etching, or a combination thereof may be used. Furthermore, the opaque portion may be the portion of the pictogram 6 or the background portion of the pictogram. The content of the pictogram 6 displayed on the decorative plate 5 is not particularly limited, but it goes without saying that various pictograms may be adopted according to the individual needs of the product.

The composite plate 3 and the decorative plate 5 are superposed so that the markings 4 and the pictograms 6 appear on the outer surfaces thereof, respectively, and the both are further laminated and covered with the transparent resin film (second protective film) 7. A thin precious metal composite plate with pictograms as shown in FIG. 3 is manufactured.

The marking surface of the noble metal thin plate 1 is not limited to that shown in FIG. 3, and the material thereof may be silver, platinum, or any other suitable material or an alloy thereof, in addition to gold.

In this thin precious metal composite plate, since the relatively weak composite plate 3 composed of the precious metal thin plate 1 and the first protective film 2 is reinforced by the decorative plate 5 made of acrylic resin or the like, it can be transported or moved manually. A situation in which the composite plate 3 is damaged or bent at the time of being prevented is prevented, and the commercial value is not impaired. Further, since the precious metal thin plate 1 is laminated and covered with the first protective film 2 and the precious metal thin plate 1 does not come into direct contact with the decorative plate 5, the precious metal thin plate 1 is not damaged or wrinkled due to friction or the like. further,
Since the composite plate 3 and the decorative plate 5 are laminated and covered with the second protective film 7, the two do not move relative to each other, breakage or wrinkle does not occur, and adhesion of dirt is prevented.

[Effects of the Invention] As described in detail above, the present invention provides a composite plate in which a transparent protective film is closely adhered to a thin plate made of a precious metal or an alloy of precious metals and marking is performed by engraving, and a partially opaque pictogram. The transparent decorative plate that has been applied is overlapped, and both are covered with a transparent protective film, so even if a thin plate of expensive precious metal is thinly spread to make it a relatively inexpensive thin plate, one side of By engraving, the other side can be provided with pictograms by the opaque portion provided on the decorative plate, and a decorative article can be provided that looks good. Moreover, the double protective film protects the precious metal thin plate from mechanical and chemical damage, and further protects the decorative plate from damage due to bending or the like, which is an excellent effect that the life of the product can be extended. Is played.
