[0011] According to the present invention, it is possible to provide an ingot having an interesting serial number engraved thereon. [Brief description of the drawings]

[0012] [Figure 1] FIG. 2 is a plan view of an ingot according to an embodiment of the present invention. [Diagram 2] FIG. 2 is a back view of an ingot according to an embodiment of the present invention. [Diagram 3] FIG. 2 is a diagram showing marks constituting a hallmark portion of an ingot according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the following, the same elements in all the drawings are given the same reference numerals, and duplicated explanations will be omitted. In addition, in the explanation in the text, the reference numerals previously described will be used as necessary.

[0014] Fig. 1 is a plan view of an ingot 10 according to an embodiment of the present invention, and Fig. 2 is a back view of the ingot 10 according to the embodiment of the present invention.

[0015] Fig. 3 is a diagram showing marks constituting the hallmark section 14 of the ingot 10 according to the embodiment of the present invention. Fig. 3(a) is a diagram showing the use of marks with motifs of 12 constellations in the hallmark section 14 of the ingot 10 according to the embodiment of the present invention, and Fig. 3(b) is a diagram showing the use of marks with motifs of 10 planets in the hallmark section 14 of the ingot 10 according to the embodiment of the present invention.

[0016] The ingot 10 includes a bullion portion 12 and a hallmark portion 14. The ingot 10 is a bullion that is worth owning not only as an asset but also as an ornamental piece.

[0017] Here, the base metal portion 12 is formed so as to facilitate the storage of metals such as gold and silver, and here has a shape similar to a chocolate bar, but of course it may have other shapes.

[0018] The base metal portion 12 will be described as having grains (protrusions 11) aligned in 5 rows and 4 columns as shown in FIG. 1, but is not limited to this matrix.

[0019] Each of the convex portions 11 arranged in 5 rows and 4 columns has a generally rectangular pyramid shape, with a groove formed between each adjacent portion, imitating a shape of a chocolate bar. The rectangular pyramid shape has an inclined side, so that light that hits the base metal portion 12 is reflected, enhancing the brilliance of the base metal portion 12.

[0020] The size of the chocolate bar having the 5 rows and 4 columns of protrusions 11 shown in FIG. 1 is 111.6 mm in the longitudinal direction and 54.3 mm in the lateral direction.

[0021] The size of each convex portion shown in FIG. 1 is such that the length of the upper surface in the longitudinal direction is 15.4 mm, the length of the upper surface in the lateral direction is 8.3 mm, the length of the lower surface in the longitudinal direction is 22.4 mm, and the length of the lower surface in the lateral direction is 13.0 mm.

[0022] Furthermore, the angle of the inclined surface of the approximately quadrangular pyramid of each convex portion can be set to approximately 57° to approximately 63°, but of course these numerical values ​​can also be changed as appropriate and can be set, for example, taking into consideration light reflection, etc.

[0023] The base metal portion 12 has been described as being in the shape of a chocolate bar having a predetermined thickness, but is not limited to this shape and may be in the shape of, for example, a Tirol chocolate bar.

[0024] The front surface 12a of the bullion part 12 has the shape of a chocolate bar as described above, but the back surface 12b of the bullion part 12 has information about the bullion part 12 engraved thereon and has a substantially flat surface for forming the hallmark part 14. The information about the bullion part 12 includes the graphic part 13 such as the product mark or figure, as well as information about the weight, purity, etc. of the bullion part 12.

[0025] The hallmark portion 14 is a mark engraved on the bullion portion 12 to distinguish the bullion portion 12 from other bullion portions. The hallmark portion 14 expresses, by means of a mark, the serial number of the bullion portion 12, the year of manufacture, and a date related to the owner of the bullion portion 12. Here, examples of dates related to the owner include birthdays and wedding anniversaries, but of course also include other dates.

[0026] The serial number is one of the most important markings because there is a possibility that counterfeits of the base metal part 12 may be made or that the metal part 12 may be stolen. Conventionally, the base metal part 12 is individually numbered, and managed so that no two pieces have the same number, but since it is just a string of alphanumeric characters, it lacks interest.

[0027] Therefore, it is preferable to express the serial number with a mark, for example, a constellation motif can be used. As shown in Fig. 3(a), the marks 16a to 16l of the 12 constellations Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces are used.

[0028] Of course, the marks may be other than the 12 constellations, and as shown in Fig. 3(b), the marks 18a to 18i of the 10 planets, namely, the Sun, Mercury, Venus, the Moon, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto, may be used. Furthermore, motifs other than constellations and planets may be used, and shapes such as anchors, helmets, swords, and shields may also be used.

[0029] Next, the operation of the ingot 10 having the above configuration will be described. Conventionally, ingots of gold, silver, etc. have been sold as assets, and the back side of the ingot is engraved with the brand logo (trademark or other mark) of the company selling the ingot, as well as purity, weight, and serial number.

[0030] The serial number is very important for managing ingots, but in the past, it was just a string of alphanumeric characters. Some people buy ingots not only as assets, but also as ornamental items, so there is a problem that a string of alphanumeric characters is not interesting. The present invention has a remarkable effect on such a problem.

[0031] The ingot 10 has a shape resembling a chocolate bar with 5 rows and 4 columns of protrusions 11 on the surface 12a side. Therefore, unlike conventional flat bars, it can be enjoyed as an ornamental piece, for example, by displaying it in a room.

[0032] Unlike the front surface 12a side, the back surface 12b side of the ingot 10 is generally flat with no protrusions 11, but is engraved with not only a graphic part 13 such as a mark, weight, purity, etc., but also a manufacturing number. Conventionally, this manufacturing number was a string of alphanumeric characters and lacked interest, but the hallmark part 14 of the ingot 10 is identifiable by combining marks 16a-16l and 18a-18i of the 12 constellations and 10 planets, which has the remarkable effect of allowing an interesting design to be created. [Explanation of symbols]

[0033] 10 ingot, 11 convex portion, 12 bullion portion, 12a front surface, 12b back surface, 13 graphic portion, 14 hallmark portion, 16a-16l marks, 18a-18i marks.
