JPH024593A - Production of precious metal composite card with picture writing thereon - Google Patents

Abstract

PURPOSE:To make the title card economical without causing deformation or damage of a sheet by a method wherein a picture writing drawn over an area greater than the surface area of a sheet of a precious metal or a precious metal alloy is duplicated in a reduced size on the surface of the sheet, and the sheet is covered by a transparent resin film. CONSTITUTION:First, a high-purity gold ingot is rolled, and is cut to the size of a calling card (for example) to obtain a sheet 1. Next, a gold score card (picture writing) 2, for example, is copied on the face side of the sheet 1 in a reduced size approximate to the size of the sheet 1 (by a commercial copying machine). Guarantee characters 4 of the maker's name, amount, purity or the like for guarantee gold are laser marked on the back side of the sheet 1. The face and back sides of the sheet 1 are then covered by acrylic resin films 5a, 5b slightly greater than the sheet 1, and marginal parts of the opposing sides of the films 5a, 5b are welded to each other, thereby binding the sheet 1 and the films 5a, 5b integrally.

Description

[Detailed Description of the Invention] "Industrial Application Field" This invention is a pictograph made of a precious metal or an alloy of precious metals that can be easily used as a souvenir, gift, or jewelry and has a property value. The present invention relates to a method for producing a precious metal composite card.

``Prior Art'' In recent years, as gold has become more popular, the units in which gold is handled have become smaller and are now bought and sold in duram units. However, when such a small amount of gold is press-molded to a certain thickness as a coin or medal, the shape is very small, so it does not look good and is not effective as a souvenir or gift. The problem was that it was thin.

For example, if you roll a gold ingot into a thin plate (for example, if you roll 1g of gold to a thickness of 15μm, it will be about the size of a business card).
Then, by applying pictographs etc. to the surface of this thin gold plate to form a thin plate with pictographs, and by coating both sides of this thin plate with pictographs with transparent resin to reinforce the thin plate, it can be used as a souvenir in the form of a card. Can be used as a gift.

Conventionally, when manufacturing a precious metal composite card with pictograms as described above, a thin plate with pictograms is obtained by stamping a thin gold plate using a mold.

``Problems that inventions are supposed to solve'' Incidentally, in recent years, sports and cultural activities have been actively carried out, and various commemorative items have been used as commemorative items. For example, certificates, trophies, etc. are mainly used as souvenirs for golf competitions, but there are items that have the contents of the scorecard written on them, are highly decorative, and can be easily held or stored. There wasn't.

Therefore, one possible way to achieve this would be to use the above-mentioned precious metal composite card with pictographs, but the actual scorecard is larger than this card, and what is written on the scorecard is different for each individual, group, etc. Due to differences in venue, date, etc., as mentioned above, when stamping on a thin gold plate using a mold, labor and
The disadvantage is that it requires a lot of time and money.

``Means for Solving the Problems'' In order to solve the above problems, the present invention provides a method of drawing on the surface of a thin plate made of a noble metal or an alloy of precious metals over a wider area than the surface of the thin plate. This is a miniature copy of a pictograph and then covered with a transparent resin film.

"Function" In the precious metal composite card with pictographs of this invention, pictographs drawn on a thin plate made of precious metals or alloys of precious metals are reduced in size and reproduced over a wider area than this thin plate. To easily, quickly and inexpensively apply pictographs of a size and content according to a thin plate.

"Example" Hereinafter, with reference to FIGS. 1 to 4, an embodiment of the method for producing a precious metal composite card with pictographs according to the present invention will be explained using a golf scorecard as the pictograph as an example. do.

First, a gold ingot with a purity of 99.99% or more is rolled to a thickness of 13 mm.
A thin gold plate 1 is obtained by finishing the µ gold plate and cutting it into business card-sized pieces.

Next, as shown in FIG. 1, a golf scorecard (pictogram) 2 is reduced to approximately the same size as the thin plate 1, and this is copied onto the surface of the thin plate 1. This reduction copying is performed using a commercially available copying machine.

Further, guarantee characters 4 such as the manufacturer's name, weight, purity, etc. for guaranteeing gold are applied to the back side of the thin plate 1 by laser marking. (See FIG. 4) Next, as shown in FIGS. 2 to 4, the front and back surfaces of the thin plate 1 are coated with a transparent acrylic resin film 5a, which is slightly larger in shape than the thin plate 1, respectively.
5b and welding the edges of the opposing surfaces to form the thin plate l and the acrylic resin film 5a, 5.
Integrate b.

The precious metal composite cards with pictographs manufactured in this way have the decorativeness and luxury of gold, and also feature memorable scores for golfers, so they can be used as souvenirs for competitions or as gifts. It is the most suitable for.

According to the manufacturing method of the above-mentioned precious metal composite card with pictograms,
Like the golf scorecard 2, pictograms drawn over a wider area than the thin plate 1 can be applied to the surface of the thin plate 1, and since no mold is required, the content can be printed according to the purpose of use. Pictograms can be easily, quickly and inexpensively applied to the surface of a thin plate 1.

In the above embodiment, the pictograms applied to the thin plate 1 are golf scorecards, but the pictographs are not limited to this, and may be records or results of various sports activities or cultural activities.

"Effects of the Invention" As explained above, according to the method of manufacturing a precious metal composite plate with pictograms of the present invention, pictograms drawn over a wider area than the thin plate made of a precious metal or an alloy of precious metals can be printed on a thin plate made of a precious metal or an alloy of precious metals. Since it is reduced in size and copied, it is possible to easily, quickly and inexpensively apply pictographs of the size and content according to the purpose of use on the thin plate.Moreover, the thin plate itself can be deformed, like an engraving on a mold. It will not be damaged.

Moreover, it has the excellent effect of contributing to the expansion of new demand accompanying the popularization of gold.
