Description

  The present invention relates to a structure of a noble metal jewelry, and more particularly to a structure of a noble metal jewelry that can contain a liquid fragrance (perfume, eau de cologne, or other aromatic liquid).

Providing fragrance to precious metal jewelry (decoration) has been proposed for a long time. For example, the following documents can be cited.
JP-A-5-179374. A method for producing a sintered compact for an aromatic noble metal. JP-A-8-269503. Clay composition for precious metal modeling. Registered utility model No. 3116544. Aromatic ornaments. Japanese Patent Laid-Open No. 11-158079. How to use moon peach.

  Patent Document 1 described above is a manufacturing device in which a precious metal fine powder (1 to 106 microns) is sintered and impregnated with a fragrance. Such a device is a manufacturing method that requires specific numerical values such as vibration filling, molding temperature, and firing time, but the patentability is denied as it can be easily devised from already known patent documents. It has been known to use impregnation of a fragrance using a porous material by firing.

  In Patent Document 2, two kinds of metal powders having different particle diameters and an organic binder aqueous solution are mixed and an attempt is made to produce a precious metal sintered product by firing. As a result, a high-density and low-shrinkage fired body was obtained, which could be manufactured in a simple firing furnace.

  The above Patent Documents 3 and 4 are devices related to a structure for imparting fragrance to an accessory, and specific structures for providing or replacing a fragrance have been proposed.

  In the above-described prior art, in order to contain a fragrance in a noble metal jewelry, a technique of forming a noble metal powder (die molding or injection molding) and sintering is used. It has been fired as required for mechanical parts, bearings, etc., and has relatively low strength. Even if the bearing is impregnated with oil, it has high mechanical strength. It is unsuitable for the manual processing to be used, and it has not been possible to impregnate a volatile fragrance with a sufficient amount for fragrance over a long period of time.

On the other hand, in the above and the literatures 3 and 4 that have been devised structurally to impart a fragrance, the advantage of maintaining the quality of the noble metal in that the main body of the noble metal accessory can be configured with the desired noble metal as before. There is.
However, in the structure of the opening and the lid (screw) for sealing the fragrance liquid as in Patent Document 3 (ring), the design of the ring is impaired, and there are structurally complicated problems such as threading. In addition, the discharge from the fragrance discharge hole formed in the lid body volatilizes in a short period of time, and there is a problem that it is difficult to expect a fragrance over a long period of time.

  In view of such problems, the present invention provides a structure of a noble metal jewelry that can dissipate fragrance over a long period of time with a simple structure, although the main body of the noble metal jewelry is made of conventional noble metal. For the purpose.

In order to achieve the above object, the structure of the noble metal jewelry according to the present invention is as follows.
A housing part 2 drilled by a drill is provided in a part of the main body 1 of the noble metal jewelry,
The sintered metal body 3 is accommodated and installed inside the accommodating part 2 in a state where a part thereof is exposed from the accommodating part 2.
The sintered metal body 3 is sintered so that the porosity becomes 25% to 50% by pressure molding and a sintering process using fine powdered powders of metals having different particle diameters that can be impregnated with the liquid fragrance. And
The upper part of the sintered metal body 3 has a stop portion 3A formed smaller than the size of the housing portion 2, and the sintered metal is deformed by caulking deformation of a part of the main body 1 to the stop portion 3A. A body 3 is held in the housing part 2;
This is a measure taken.

In the present invention, the liquid fragrance means already known liquid natural and synthetic fragrances containing fragrance components such as various perfumes and eau de cologne.
The above-mentioned housing portion is usually drilled with a drill, but a tool such as a punch may be used. This may be done at the time, and the same holds for the housing and caulking of the sintered metal body 3.
Further, the sintered metal body 3 is preferably made of substantially the same noble metal as the main body 1, but may be made of a completely different metal (for example, the main body is platinum and the sintered metal body is stainless steel). It ’s good.

  According to the structure of the noble metal jewelry according to the present invention, the main body of the noble metal jewelry is made of the same noble metal as before, so that the quality of the noble metal is maintained and the simple drilling and caulking means for the main body is achieved. With the structure, the sintered metal body that can be impregnated with the liquid fragrance can be easily held, and thereby, the fragrance can be diffused over a long period of time (from the surface of the sintered metal body to the fragrance. Can be recharged at any time).

The precious metal jewelry of the present invention is preferably implemented as follows.
The main body 1 is preferably a ring, a bracelet, a pendant, an earring, an earring, a brooch, a cowse, a tie tack, or a necklace.
As described above, examples of the main body of the accessory include those described above, and the present invention can be applied to any of them, from which a desired fragrance can be volatilized.

When the main body 1 is a ring 1A and the housing portion 2 is provided on the inner surface of the ring 1A opposite to the design portion 1B, the original design of the outer surface of the ring is As it is, fragrance volatilization from the part in contact with the finger becomes possible.
Therefore, the sintered metal body can be accommodated and laid in the main body irrespective of (without affecting) the design processing as a ring.

In addition, when the said main body 1 is platinum, it is preferable that the said sintered metal body is also platinum, but it is good also as a sintered metal body of another metal (for example, stainless steel) completely.
The sintered metal body may be composed of a mixture of a main metal and an additive metal. In this case, for example, when the main body is platinum, the main metal is platinum, and the additive metal is palladium, ruthenium. , Iridium, rhodium, or a mixture thereof.
Thus, since the density (21.45) is high when the main metal is platinum, even if the porosity is 50% by using 90 parts by weight or more, the weight feeling is not impaired, The value as precious metal jewelry is hard to be damaged. And since the volume per unit weight increases, it looks good even if it is processed into the required design, but the value as a precious metal is only due to the ratio with other mixed metals, so its quality deteriorates It is not a thing. And the required fragrance is emitted from these accessories.

  The main body 1 may be gold, and the main metal of the sintered metal body may be gold, and the additive metal may be one of silver, palladium, ruthenium, iridium, and rhodium, or a mixture thereof. Since gold has a high density (19.32), even if it is used in 90 parts by weight or more and the porosity is 50%, the feeling of weight is not impaired and the value as a noble metal accessory is not easily impaired. And since the volume per unit weight increases, it looks good even if it is processed into the required design, but the value as a precious metal is only due to the ratio with other mixed metals, so its quality deteriorates It is not a thing. The required fragrance is emitted from these accessories.

A preferred embodiment of the structure of the noble metal jewelry according to the present invention will be described in detail below.
Here, platinum ring 1A will be selected and described as a precious metal accessory.
First, as shown in FIG. 1 to FIG. 4, a housing part 2 is provided on a part of a main body 1 of a ring 1A of a noble metal jewelry, here, on the inner surface opposite to the design part 1B of the ring 1A. Provided by perforations.

FIG. 1 shows an overall perspective view of the ring 1A, and the following is a cross-sectional view showing a manufacturing process, FIG. 2 is an enlarged cross-sectional view, showing drilling by a drill 5, and drilling by a drill 5 Although performed in two steps, the first step drilling is shown.
Since the ring 1 has an annular shape with a diameter of about 15 mm here, the drill 5 is attached to the ring 1A from one side so as not to contact the design portion 1B of the ring 1A (the outer surface portion when fitted on the finger). The first perforation is performed in a state where it is advanced to the center P of the perforation position on the inner surface of the annular portion opposite to the design portion 1B and is slightly inclined with respect to the vertical. Here, the diameter of the drill 5 was 1.2 mm.

Next, as shown in FIG. 3 of the enlarged cross-sectional view, the drill 5 is advanced from the other side of the ring 1A toward the center of the drilling position in a slightly tilted state. The second drilling is performed with a slight deviation.
As a result, the opened hole is not a perfect circle but an ellipse displaced by about 0.1 mm. About the perforation depth, although it changes with the thickness of the said ring 1A, a design, and the sintered metal body 3 accommodated, it is about 1-2 mm.
Thus, the accommodating part 2 is formed in the inner surface of the annular part of the ring 1A.

FIG. 4 is a perspective view showing a sintered metal body 3 (pellet shape) mainly containing platinum housed in the housing portion 2, which is a substantially cylindrical body, the upper part of which is from the dimensions of the housing portion 2. 3A has a stop portion 3A formed to be small. That is, the stopper 3A is formed like a chamfer.
FIG. 5 is a cross-sectional view showing a state in which the sintered metal body 3 is housed in the housing portion 2 in a state where a part of the sintered metal body 3 is exposed, and FIG. 6 is a cross-sectional view, and then the housing portion. 2 shows a state in which a part 1C of the body 1, that is, a part 1C of the main body 1 is deformed by a caulking method using a punch 4, and the sintered metal body 3 is locked and held in the housing part 2.
Thus, in a state where the sintered metal body 3 (about 0.5 mm ³ ) section is locked and held in the housing portion 2, 0.1 mmg to 0.2 mmg of a desired liquid fragrance is formed from the surface. Apply and impregnate to a certain extent.
In the above embodiment, the sintered metal body 3 is made of platinum as a main metal, but it goes without saying that another sintered metal may be used.

Next, the sintered metal 3 whose main metal is platinum will be described.
The sintered metal body 3 is sintered so that the porosity becomes 25% to 50% by pressure molding and sintering process of fine powdered powder of metal having different particle sizes that can be impregnated with liquid fragrance. It is a thing.
Here, platinum fine powder was prepared as a main metal having a different particle diameter. A platinum pre-mix was used in which the particle size of platinum was mainly 20 to 30 microns, 70 to 75 parts by weight, and the remaining amount of 150 to 200 microns was mixed. By increasing the number of fine particles, the smoothness of the metal surface after sintering is improved, and the gloss as a jewelry can be secured.

  Thereafter, platinum fine powder was put into a die and pressure-molded so as to form a substantially cylindrical body having a desired shape, here, a chamfer that can be attached to the ring 1A. And it shifted to the sintering process and baked at about 1500 degrees, which is slightly lower than 90% of the melting point of platinum (1773.5 degrees), to obtain a porosity of 40%. Therefore, the density of this substantially cylindrical body is about 12.87, and it has a feeling of weight as a noble metal accessory, and can be impregnated with sufficient liquid fragrance.

After the fired raw material was mounted on the ring 1A, 0.2 mmg of a fragrance was impregnated from the surface. Thereafter, the process was shifted to a packaging process and wrapped with a transparent soft synthetic resin film.
The porosity described above is 40%, but if it is 25% or less, the mechanical strength becomes large, and a sufficient amount of fragrance is provided to make it difficult or inefficient to process as an accessory (finally manual work). There is a problem that it is difficult to impregnate the agent, and conversely, if the porosity exceeds 50%, the density of a noble metal with high density becomes too small (bulk specific gravity), making it difficult to obtain a sense of weight as a noble metal ornament. Is inappropriate.

In addition, the following was used for the sintered metal 3 containing platinum as a main metal, and although not shown, a pendant (cross) was selected as the main body 1.
Here, platinum fine powder was prepared as a main metal having a particle size of 90 parts by weight or more, here 97 parts by weight. A platinum pre-mix was used in which the particle size of platinum was mainly 20 to 30 microns, 70 to 75 parts by weight, and the remaining amount of 150 to 200 microns was mixed. By increasing the number of fine grains, the smoothness of the metal surface after sintering is improved, and gloss can be secured as a jewelry.

Then, ruthenium fine powder was selected as the additive metal, and 10 parts by weight or less, here 3 parts by weight, was prepared and mixed with the platinum powder. The fine pine is of 20 to 30 microns.
Thereafter, the obtained mixed powder was put into a die and pressed into a predetermined original shape (rod-like body) assuming a desired shape, here a pendant (for example, a cross). Then, the process proceeds to the sintering process, and firing is performed at about 1500 degrees which is slightly lower than about 90% of platinum (1773.5 degrees) having a melting point lower than that of the mixed metal ruthenium (2500 degrees), and the porosity is 50%. Got stuff.

The obtained bar-shaped sintered metal (about 5 mmg) was accommodated in a recess formed on the back of the cross, and fixed with caulking as described in Example 1 to arrange the shape of the pendant as the final product. It became jewelry. Since this sintered metal is a rod-shaped body, the circular arc portion having a circular cross section corresponds to the chamfered portion described above, and when it is accommodated in the concave portion, a space is automatically formed at the location of the arc portion and the concave portion edge. You can make a caulking.
Then, the obtained pendant rod-shaped body sintered metal was impregnated with 2.00 mmg of a predetermined liquid fragrance from its surface, and then the pendant was packaged with a transparent non-breathable packaging material.

  When the main metal is platinum, the additive metal may be, for example, 7 parts by weight of palladium, iridium, rhodium, or a mixture thereof in addition to ruthenium.

Further, as sintered metal 3, gold is selected as a fine powder of main metal having a different particle size of 90 parts by weight, and silver is selected as a fine powder of at least one additional metal having a different particle size of 10 parts by weight, These fine powders are mixed, and the obtained mixed powder is put into a die and pressed into a required shape, here a pellet shape to be accommodated in an annular bracelet similar to the ring 1A. What was sintered so that the porosity was 25% was also used.
In addition, when the said main metal is gold | metal | money, you may use 1 type of palladium, ruthenium, iridium, rhodium or those mixtures other than said silver as an additional metal.
Moreover, in the said corner | angular embodiment, although the ring, the bracelet, and the pendant were illustrated as an example of accessories, it is applicable also to an earring, a piercing, a brooch, a cowse, a tie tack, or a necklace.

  The precious metal accessory according to the present invention is an accessory that can repel the fragrance for a long period of time, and is excellent in processability as an accessory, such as a ring, a bracelet, etc. It can be implemented as a pendant, earring, earring, brooch, cowse, tie tack or necklace.
