Description

[Detailed Description of the Invention] [Industrial field of application] This invention can be used easily 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, 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 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 a gold ingot is rolled into a thin plate shape, and the surface of this is marked by engraving or the like to give a pattern or a character according to the purpose. In this case, for example, if 1 g of gold is extended to a thickness of 20 μm, it will be about the size of a business card, will look good enough, and patterns and characters can be easily distinguished, which is suitable for souvenirs.

[Problems to be Solved by the Invention] However, in the conventional techniques as described above,
Since it is made of a very thin plate, it has low strength, is easily deformed or damaged, and is inconvenient to handle. In addition, the contents of the above markings will differ depending on the purpose used as souvenirs and gifts, and for that purpose it is necessary to change according to individual orders, but using a mold However, such a method cannot cope with such orders, and there is a problem that the cost is high because the lot is small. Therefore, for example, it is conceivable to provide a composite decorative plate in which a thin noble metal plate and a transparent decorative plate with a pattern formed on an acrylic plate or the like are overlapped and integrated. In this way, the precious metal thin plate is mass-produced, and the above-mentioned object can be achieved at low cost by arranging the characters and patterns of the decorative plate in various ways. However, since the precious metal thin plate itself is very difficult to handle, there are problems that the process of manufacturing the composite decorative plate is difficult and the finish is not good.
Furthermore, if the thickness of the precious metal thin plate becomes less than a certain value, the thin plate becomes translucent, the pattern can be seen through from the back side, the decorative function deteriorates, and the commercial value decreases. .

[Means for Solving the Problems] In order to solve the above problems, the thin precious metal composite plate with pictograms according to claim 1 of the present invention has a surface roughness of 0.2S.
A thin plate made of a precious metal or an alloy of precious metals of 0.8 S and having at least one of the front and back surfaces partially provided with pictograms is coated with a transparent protective film.

The thin precious metal composite plate with pictograms according to claim 2 is a thin plate made of a precious metal or an alloy of precious metals having a surface roughness of 0.2S to 0.8S covered with a transparent first protective film, and a partially opaque pictogram. And a transparent decorative plate on which the above is applied, and both are covered with a transparent second protective film.

Further, the thin precious metal composite plate with pictograms according to claim 3 is
In Claim 2, at least one of the front and back surfaces of the thin plate is partially provided with pictograms.

Here, the surface roughness of the surface of the thin plate is 0.2S ~ 0.8S, when the surface roughness is less than 0.2S, the gloss of the metal surface becomes strong and the pictogram becomes difficult to see, and the surface roughness Is 0.
This is because if it exceeds 8S, the surface will be rough and will not look good.

[Operation] In the thin precious metal composite plate with pictograms according to claim 1 of the present invention, the precious metal thin plate is covered with a protective film to be reinforced and protected from mechanical and chemical wear.
Even if a few grams of gold is thinly stretched, its deformation and damage can be prevented, and it is easy to handle.
It can be easily possessed, stored, and the like, and further, various ornamental products made of it can be easily manufactured.

Further, in the thin precious metal composite plate with pictograms according to claims 2 and 3, by superimposing the precious metal thin plate and the transparent decorative plate having a partially opaque pictogram,
From the side of the decorative plate, the pictograms on the decorative plate appear to stand out against the background of the precious metal color. When the decorative plate is only one surface of the precious metal thin plate, the marking applied to the precious metal thin plate can be seen from the opposite side, and a precious metal composite plate having pictograms having different color tones and contrasts on both sides of the plate can be obtained. Since the noble metal thin plate is covered with the first protective film, the translucency of the noble metal thin plate is canceled by the refraction of light on the surface between the first protective film and the noble metal thin plate. Therefore, when viewed from the noble metal thin plate side, the color tone of the noble metal is not reduced, and the pattern of the decorative plate is prevented from being seen through. Since the transparent decorative plate reinforces the noble metal plate, it does not easily deform even when an external force is applied, and it is easy to handle and store. Since the decorative plate and the noble metal thin plate are covered with the second protective film, adhesion of dirt, abrasion, corrosion, etc. are prevented.

Further, in any of the precious metal thin-wall composite plates with pictograms according to any one of claims 1 to 3, the precious metal thin plate has a surface roughness of
Since it is 0.2S to 0.8S, the pictograms are easy to see and look good.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

(Embodiment Corresponding to Claim 1) FIGS. 1 to 4 show a first embodiment, and in these drawings, reference numeral 1 denotes a gold thin plate. This thin plate 1 has a thickness of 15μ by repeatedly rolling a massive material with a purity of 99.99% or more.
m, and the surface roughness was finished to 0.2S-0.8S, and it was cut into a business card size. The back surface of the material was irradiated with a laser beam from a YAG (yttrium-aluminum-garnet) laser generator. , Emoji 2 that represents quality and weight is applied.

In this process, as a means for moving the laser beam, a well-known method of changing the irradiation position of the laser beam in the XY axis plane by controlling the generator is adopted. And by changing the intensity of the laser beam,
The depth of the concavities and convexities forming the pattern can be appropriately adjusted. For example, if this is suppressed to about 1/10 of the plate thickness, the situation where the thin plate 1 itself is transparent and the front and back patterns are overlapped can be avoided. Does not occur. Further, since the mold is not pressure-bonded, the unevenness of the front does not appear on the back. In this way,
By combining the device for moving the laser beam with an appropriate figure input device, it is possible to easily, quickly and inexpensively apply arbitrary figures, patterns, characters, portraits, certification marks and the like to the thin plate.

The display content on the precious metal thin plate 1 is not particularly limited, but it is appropriate to make the material, quality, weight, etc. of the precious metal plate itself part of the display.

The shape of the noble metal thin plate 1 is not limited to the rectangular shape, and other suitable materials such as silver, platinum, etc., or alloys thereof may be used as the material. As shown in FIG. 2 and FIG. In addition, the front and back surfaces of the above-mentioned precious metal thin plate 1 are made of transparent resin and
A little larger (longitudinal and lateral dimensions are about 1mm longer on one side) protective film (first protective film) 4,4 is coated and crimped,
The thin precious metal composite plate 5 with pictograms is formed by binding these edges together.

In the thin precious metal composite plate 5 with pictograms having such a configuration, since the front and back surfaces of the precious metal thin plate 1 are covered and reinforced with the protective film 4, even if a few grams of gold is thinly stretched, its deformation In addition, it is possible to prevent damage, and it is possible to provide a decorative article with a relatively large area (about a business card) that looks good. Moreover, it is easy to handle and can be easily carried and stored.

Also, since the surface roughness of the precious metal thin plate 1 is 0.2S to 0.8S, the gloss of the metal surface does not become strong and the surface does not feel rough, so the pictogram 2 is easy to see and looks good. To do.

Here, the reflectance was obtained by measuring the reflected light when white light was applied to the surface of a gold thin plate having a different surface roughness and a purity of 99.99% by a photometer. The results are shown in FIG. As shown in this figure, when the surface roughness is less than 0.2S, the reflectance sharply increases and the surface gloss becomes strong, making it difficult to see pictograms, while when it exceeds 0.8S, the surface becomes rough. I felt it, and it became difficult to see small letters and patterns.

(Embodiment corresponding to claim 2) FIGS. 5 to 7 show a second embodiment.
In the precious metal composite plate with pictograms shown in these figures, a transparent decorative plate 10 is superposed on the surface of the thin precious metal composite plate 5 with pictograms, and this is covered with a protective film (second protective film) 11 made of a transparent resin. It was done.

As shown in FIG. 5, the transparent decorative plate 10 is a transparent plate made of a material such as a resin such as acrylic and glass, and a pictogram 12 formed of an opaque portion on the surface thereof. The material of the transparent decorative plate 10 does not necessarily have to be highly rigid, and may be one having appropriate flexibility,
The thickness is set appropriately. Further, for the opaque portion, an appropriate method such as coating of a paint, relief engraving, etching, or a combination thereof may be used. Furthermore, the opaque portion may be the portion of the pictogram 12 or the background portion of the pictogram. The emoji part may be cut out to expose the noble metal in that part. This transparent decoration board
Although the content of the pictogram 12 displayed on 10 is not particularly limited, for example, in the case of a wedding gift, a different display is displayed for each product, such as the name of the bride and groom, and other items such as business cards and events. Memorials, famous paintings and reproductions of Gesyne are considered. As a relatively easy concrete method, there is a method using a copy machine, which includes thermal copying, laser copying,
According to photographic copying, vivid color copying can be easily performed based on an arbitrary original plate.

Then, the thin precious metal composite plate 5 with a pictogram and the transparent decorative plate 10 are overlapped so that the pictograms 2 and 12 appear on the outer surfaces, respectively, and both are formed of a protective film made of a transparent resin.
A thin precious metal composite plate 15 with a pictogram is manufactured by further laminating and coating with 11. The thin precious metal composite plate 15 with pictograms is configured by using the thin precious metal composite plate 5 with pictograms, but the surface roughness is 0.
As long as it is a precious metal plate of 2S to 0.8S, the surface of this precious metal thin plate need not have pictograms.

The thin precious metal composite plate 15 with the pictograms having the above-mentioned configuration is damaged or bent when the precious metal thin plate 1 is reinforced by the transparent decorative plate 10 made of acrylic resin or the like, during transportation or transfer by manpower. The situation is prevented and the product value is not impaired. In addition, the entire protective film 11
Is laminated and coated, the precious metal thin plate 1 and the transparent decorative plate 10 do not move relative to each other, the precious metal thin plate 1 is not damaged or wrinkled, and dirt is prevented from adhering. Furthermore, since the noble metal thin plate 1 is covered with the protective film 4, the translucency of the noble metal thin plate 1 is canceled by refraction of light on the surface between the protective film 4 and the noble metal thin plate 1, and the noble metal thin plate 1
When viewed from the side, the color tone of the precious metal thin plate 1 is not deteriorated, and the pictogram 12 attached to the transparent decorative plate 10 on the front side cannot be seen through. In addition, since the surface roughness of the precious metal thin plate 1 is .2S to 0.8S, the gloss of the metal surface does not become strong, and the surface does not feel rough, so the pictograms 2 and 12 are easy to see. And it looks good.

FIG. 8 shows a third embodiment of the present invention, in which a noble metal thin plate 1 covered with a protective film 4 is a pair of transparent decorative plates 10.
It is sandwiched between a and 10b, and these are integrated into a protective film 11
It is covered by. In this case,
The content displayed on the precious metal thin plate 1 may be displayed on the transparent decorative plates 10a and 10b, and it is not necessary to mark the precious metal thin plate 1. The transparent decorative plates 10a, 10b and the noble metal thin plate 1 may be fixed with an appropriate adhesive. The materials and indications of the transparent decorative plates 10a and 10b are not different from those described above.

In this embodiment, the decorative / display effect and the reinforcing effect of the transparent decorative plate 10 described above are further enhanced. In particular, it has a feature that it can be adopted even when the precious metal thin plate 1 becomes thinner.

[Advantage of Invention] As described in detail above, according to the thin-walled precious metal composite material with pictograms according to claim 1 of the present invention, the precious metal thin plate is covered with the protective film to be reinforced and protected from mechanical and chemical wear. Therefore, even if a few grams of gold is thinly spread, its deformation and damage can be prevented, and a decorative article having a relatively large area (about a business card) can be provided. Moreover, it is easy to handle and can be easily carried and stored. Furthermore, the surface roughness of the precious metal sheet is 0.2S.
Since it is ~ 0.8S, the gloss of the metal surface does not become strong, and the surface does not feel rough,
The emoji on this surface is easy to see and looks good.

Further, according to the precious metal composite plate with pictograms of claims 2 and 3, since the precious metal thin plate covered with the transparent first protective film is reinforced by the transparent decorative plate, it is transported or transported by manpower. It prevents the situation of damage or bending at the time of, etc., and does not impair the commercial value, and since the whole is covered with the second protective film, the precious metal thin plate and the transparent decorative plate move relative to each other. Without causing damage or wrinkling of the noble metal thin plate, preventing adhesion of dirt, and further, since the noble metal thin plate is covered with the first protective film, there is no gap between the first protective film and the noble metal thin plate. Refraction of light on the surface cancels out the translucency of the precious metal thin plate, and when viewed from the side of the precious metal thin plate, the color tone of the precious metal thin plate is not lost, and the pictograms attached to the transparent decorative plate on the front side can be seen through. No. Therefore, the decorative effect is excellent, the useful life of the product is long, and the product value can be maintained for a long period of time. Furthermore, since the surface roughness of the precious metal thin plate is 0.2S to 0.8S, the gloss of the metal surface does not become strong, and the surface does not feel rough, so the pictograms on the transparent decorative plate are easy to see and It looks good.
