Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention has a precious metal block embedded therein which can be easily used as a souvenir or a gift, and has a decorative value and a cash value. It concerns plastic cards.

(Prior art) Conventionally, business cards using noble metals such as platinum, gold and silver,
Since the ornamental card has scarcity value, cashability, luxury, and decorative aesthetics, it is directly stamped on a noble metal foil (Japanese Patent Laid-Open No. 1-275131) or stamped from a noble metal foil or a laminated sheet ( (Japanese Utility Model Application Laid-Open No. 5050927) or printed on a laminate (JP-A-1-275138).
In addition, in recent years, small precious metal ingots engraved with designs, patterns, characters, and the like have been widely used in souvenirs and gifts as gold handling units have become smaller as gold has become more popular in recent years.

(Problems to be solved by the invention) By the way, business cards and decorative cards using noble metal foil
For example, rolling 1 gram of gold to the size of a business card would result in a thickness of about 0.01 mm, which would be less than the weight of gold, far from the original value of gold, or very thin When engraving for a board, there is a defect that the mark of the engraving remains on the back side, which lowers the commercial value. In particular, when redeeming precious metal foils, it is usually disadvantageous in terms of redeemability, since dissolution and test treatments are usually required, and the costs for these must be borne. However, even standardized noble metal ingots with patterns, patterns, characters, etc. engraved on the surface, when the unit weight per small piece was small, did not have a sense of volume and did not look good as souvenirs or gifts. .

Therefore, the present invention aims to provide a plastic card in which small letters, patterns and patterns are clearly displayed, and have a large volume as a souvenir or a gift, and in which a small precious metal block that can be easily made is embedded. is there.

(Means for Solving the Problems) According to the present invention for solving the above problems, at least one layer of a plastic plate in which a standardized noble metal block is embedded and printed or engraved with a pattern, pattern, character, or the like is imprinted. A hologram is attached to the plastic plate, and transparent oversheets are laminated on both surfaces of the plastic plate. Examples of the type of plastic material include biphenyl chloride, polyvinyl chloride polyethylene, and polymethylene resin.

(Operation) The plastic card in which the noble metal lump of the present invention having the above structure is embedded is a standardized noble metal lump (a pattern,
Holograms for preventing forgery by printing or engraving designs, patterns, characters, etc. on the front and back surfaces of a plastic plate composed of one or two layers using coins, medals, precious metal bars, etc. engraved with patterns, characters, etc. Paste a hole of the same size as the precious metal lump, embed the standardized precious metal lump, and laminate a transparent oversheet on the front and back of the plastic plate, so the pattern printed on the plastic plate , Patterns, characters, etc. are clear, and the standardized noble metal ingot has a cash property, and forgery can be prevented by the hologram stuck on the surface.

(Embodiment) An embodiment of a plastic card according to the present invention in which small noble metal blocks are embedded will be described with reference to the drawings. As shown in FIGS. 1a and 1b, polyvinyl chloride (hereinafter abbreviated as "PVC") plates 2, 3 having a width of 54 mm, a length of 85.5 mm, and a thickness of 0.5 mm are shown in FIG.
The letters 5 are printed on the surface of the PVC laminate 4 and the first and the second faces are left 5 mm apart from the end face A and the end face B.
A hole 6 having a width of 9 mm and a length of 14 mm was formed as shown in FIG.
As shown in Fig. 1e, width 9mm, length 14mm, edge thickness 0.8mm
1g of the gold ingot 1 was buried as shown in FIG. 1f, and a quality assurance mark of 15 mm in width and 20 mm in length was marked as shown in FIG. 1g except for an edge 5 mm from the end face B and end face C. A hologram 7 is attached as shown in FIG. 1h, and transparent oversheets 8 and 9 of the same size as the PVC plates 2 and 3 as shown in FIGS. As shown in FIG. 2, a plastic card 10 in which a small nodule was embedded was obtained by thermocompression bonding on the front and back surfaces.

Since the plastic card 10 in which the noble metal lump having such a structure is embedded uses a standardized noble metal lump (in the embodiment, 1 g of gold bullion small lump 1), the value as a noble metal lump is maintained. There is no loss of cash.

Designs, patterns, letters, etc. 4 can also be printed directly on the PVC boards 2 and 3 so that they are clearly displayed. Even if they are engraved, the appearance is beautiful by stacking the engraved back sides of the two PVC boards back to back. Can be finished into cards.
In addition, by attaching the hologram 7 of the quality assurance mark, it also prevents counterfeiting, and the transparent oversheet thermo-compressed on both the front and back sides of the card protects precious metal lumps,
In addition, it increases the commercial value of the completed card and can be widely used for souvenirs and gifts.

In the above embodiment, the holes 6 are formed in the PVC plates 2 and 3 and the small metal ingots 1 are embedded in the holes 6. However, the holes 6 are formed only in the PVC plate 2 and the holes 6 are formed in the PVC plate 3. The layers may be laminated without opening, and the gold bullion 1 may be embedded in the bottomed hole. or
The PVC plate may be a single layer.

The size of the precious metal small lump-embedded plastic card of the present invention can be changed according to the purpose of use such as birthday cards, identification cards, credit cards, calendars, timetables, golf gifts, wedding gifts, business cards, and the like. is there.

(Effect of the Invention) As can be seen from the above description, the plastic card in which the noble metal block of the present invention is embedded is standardized, so that the precious metal block having cash can be used as it is while maintaining a good-looking volume feeling. Since the plastic plate is clearly printed or engraved with characters, designs, patterns, etc., it can be used for a wide range of applications.
