Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing hollow jewelery which is free from deformation and the like.

[0002]

2. Description of the Related Art Conventionally, hollow jewelery having a hollow interior has been proposed.

Hollow jewelery has an advantage over hollow jewelery in that the same amount of gold, for example, can be used to make jewelery with a large volume.

By the way, it is common to attach appropriate fittings to jewelry, and hollow jewelry is no exception. Specifically, a fitting is attached to the hollow jewelry piece at an appropriate position by brazing.

The brazing of the fitting naturally involves heating. However, the heating of the brazing causes the air inside the hollow jewelery to expand and contract, causing the hollow jewelery to be distorted and impaired. It often happens that it becomes a good product.

[0006] The present invention has a technical object to provide a method for manufacturing a hollow jewelery which solves the above problems.

[0007]

The gist of the present invention will be described with reference to the accompanying drawings.

Appropriate fittings 2 in place on the hollow jewelery body 1
A hole is formed in the hollow jewelery main body 1 in the vicinity of the mounting location of the fixture 2, and then the fixture 2 is brazed to the hollow jewelery body 1 at a proper position. hand,
The present invention relates to a hollow jewelery manufacturing method characterized in that the hole a is closed by an appropriate means that does not require heat.

[0009]

The hole a is formed before brazing the fixture 2, and after the brazing is completed, the hole a is closed by an appropriate means that does not require heat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A drawing is an embodiment of the present invention applied to a method of manufacturing a hollow pierce, which will be described below. Needless to say, the present invention can be applied to earrings, rings, etc. in addition to piercings. For example, a U-shaped mother body 5 is formed by a mold using a member that has conductivity and can be melted at a predetermined temperature, such as brass or silver (see FIG. 1).

A metal layer 6 made of, for example, gold or platinum is formed on the outer surface of the base 5 by electroforming (see FIG. 2).

Subsequently, an elution hole 7 penetrating the metal layer 6 is provided, and in order to make the inside hollow, the mother body 5 inside the metal layer 6 is eluted from the elution hole 7 by heating to the predetermined temperature. Hollow U-shaped shell 4 having elution holes 7 is formed
(See Figure 3).

Then, a small hole 3 (diameter of about 0.3 to 0.4 mm) is bored in a conspicuous place near the place where the fixture 2 is attached (see FIG. 4).

Subsequently, the fixture 2 made of, for example, 18K is brazed to the shell 4 at an appropriate position (see FIG. 4).

Subsequently, the inside of the hollow jewelry main body 1 is washed and dried, and then the elution hole 7 is closed by brazing (see FIG. 5).

Subsequently, the small holes 3 are closed by an appropriate means that does not use heat, for example, synthetic resin, adhesive, etc., to completely seal the hollow jewelery body 1 (see FIG. 6).

Therefore, according to the present embodiment, the fixture 2
The heat in the hollow jewelery body 1 generated when brazing is discharged from the elution holes 7 and the small holes 3, and the heat in the hollow jewelery body 1 generated when closing the elution hole 7 is small holes. Since it is exhausted from 3, it is possible to avoid expansion and the like in the hollow jewelry main body 1. Further, since the hollow jewelry main body 1 is completely sealed, for example, even if the user wears the pierced ears and enters a pool or the like, water does not enter the pierced ears.

The fixture 2 may be brazed and then the elution hole 7 may be closed as described above, or the fixture 2 may be brazed after the elution hole 7 is closed. In the former case, the elution hole 7 and the small hole 3 share the role of the air vent hole when brazing the fixture 2 as described above (therefore, the small hole 3 is formed after brazing the fixture 2). Alternatively, in the latter case, the small holes 3 will share the role of the air vent holes when brazing the fixture 2.

[0019]

As described above, according to the present invention, the heat generated when the fitting is brazed to the hollow jewelery body can be exhausted from the hole, and thus a high quality hollow jewelery which is not deformed is provided. You will be able to do it.
