Next, a mode for carrying out the present invention will be described with reference to the drawings.

As shown in FIG. 1, the method for manufacturing a decorative article with a nacre of the present embodiment comprises steps S01 to S07. Hereinafter, the process will be described in order.

[Making a nucleus made of a model imitating a decorative article] (S01)
In step S01 shown in FIG. 1, a core made of a modeled object imitating a decorative article is produced. The decorative article of the present invention is an article having a design in which characters and figures are projected, and the longest part in a plan view is 15 mm and the tallest part in a side view is 5 mm. That is, it is preferable that the model has a length of 15 mm or less and a height of 5 mm or less in consideration of the survival rate of the shellfish. Designable items include badges (company emblems, emblems, etc.), tie pins, tie clips, hairpins, necklaces, bracelets, anklets, earrings, rings, cuff buttons, collar decorations, memorial items, and the like.

In this embodiment, as shown in FIGS. 2 and 10, the decorative article 1 is a hemispherical company emblem (diameter 15 mm, height 8 mm) in which the letter “R” is projected. The modeled object imitating this decorative article is produced by a stereolithography method or a three-dimensional printer. Therefore, it is possible to easily obtain a plurality of shaped objects having the same shape, pattern, and dimensions desired by the creator. This model is preferably made of resin, which does not cause rust and has a high survival rate of shellfish during cultivation. In this embodiment, a core 2 of a model made of a methacrylic resin or an acrylic resin imitating a decorative article is produced by a three-dimensional printer (see FIG. 11).

[Adhesion of the prepared shaped object to the inner surface of the shell] (S02)
In step S02 shown in FIG. 1, a core made of the produced model is adhered to the inner surface of the shell. In this embodiment, as shown in FIG. 3, the core 2 of the two shaped objects is adhered to the inner surface of one of the shells near the mantle, which is the concave surface of the bivalve 3, with a quick-drying adhesive. The soft mantle is the organ that makes the hard shell. Bivalves are all bivalves such as Akoya pearl oysters, black pearl oysters, white pearl oysters, mabe oysters, and freshwater pearl oysters.

[Formation of nuclear encapsulation consisting of nacre by culturing shellfish] (S03)
In step S03 shown in FIG. 1, shellfish are cultivated to form a nuclear encapsulation composed of nacre. The present invention utilizes a technique of hemispherical pearl cultivation method in which live shellfish are biomineralized (a reaction in which organisms make minerals) to interrupt and make pearls. As shown in FIGS. 12 and 13, during this biomineralization, the nucleus 2 of the model is encapsulated and immobilized by the nacre encapsulation 4 (see FIG. 4). .. After adhering the core 3 of the modeled object to the inner surface of the shellfish, the shellfish cultivation is started. In this embodiment, the aquaculture period varies depending on the type of shellfish, the aquaculture conditions, the size of the modeled object, and the like, but is about half a year to about one year.

[Cut out the encapsulation body and shell with a core with a cylindrical drill] (S04)
In step S04 shown in FIG. 1, after culturing for a predetermined period, the encapsulation with a nucleus and the shell are cut out with a cylindrical drill. A cylindrical cutter is attached to the tip of an installed drill machine (not shown) and the cutter is rotated to cut out a cored encapsulation from the shell, as shown in FIG. In FIG. 4, reference numeral 4 is an encapsulation body made of nacre, reference numeral 2 is a core of a modeled object, and reference numeral 5 is a shell. The cut out shell is circular. If the core of the sculpture is a rhombus, heart shape, triangle, or other polygon, use a cylindrical cutter with an inner diameter larger than the longest diameter of those shapes to cover the entire encapsulation with a core. break the ice.

[Preparation of Mold for Decorative Article of Encapsulation after Nuclear Removal] (S05)
In step S05 shown in FIG. 1, the encapsulation body after taking out the nucleus is manufactured as a molding mold for a decorative article. To remove the core of the model from the encapsulation, dip the encapsulation with the core in hot water at 80 ° C to 100 ° C for 5 to 15 minutes, as shown in FIGS. 5 (a) and 5 (b). In addition, the core 2 and the shell 5 of the model can be taken out from the encapsulation 4 without causing the encapsulation 4 made of nacre to lose its shape. Thereby, the encapsulating body 4 can be manufactured as a molding mold for a decorative article.

[Formation of a cured resin product by injecting and curing a resin solution into a mold] (S06)
In step S06 shown in FIG. 1, a resin liquid is injected into a molding die and cured to form a cured resin product. As shown in FIGS. 6A and 6B, the resin liquid 6 is injected into the encapsulation body 4 made of nacre. In this embodiment, the resin liquid 6 is a two-component epoxy resin that is a room temperature curable resin. In addition to this, liquid curable resins such as urethane resin, polyimide resin and unsaturated polyester resin can be used. It is preferable that the resin liquid 6 is colored, translucent, or opaque because the characters and figures that are projected are clear. It is preferable to inject a colored, translucent, or opaque resin liquid only in the protruding portion, and to inject the transparent resin liquid into the other portions because the characters and figures are more prominent and can be clearly seen. As shown in FIG. 6B, the resin liquid 6 is injected so as to fill the inside of the encapsulating body 4. By injecting the resin liquid 6 and then leaving it at room temperature (room temperature), as shown in FIG. 7, a cured resin 7 covered with an encapsulating body 4 made of nacre is formed.

[Covering and sealing the bottom surface of the cured resin material with a base having a mounting tool for mounting the adherend] (S07)
In step S07 shown in FIG. 1, the bottom surface of the cured resin product is covered with a base having a mounting tool for mounting the adherend to seal the encapsulating body. In this embodiment, as shown in FIG. 8, the bottom surface of the cured resin 7 covered with the nacre 4 is covered with an easy-to-process disk-shaped lid 8 such as a shell. 4 is sealed (see FIGS. 8 (a) and 8 (b)). If there is an excess portion (burr) around the encapsulating body 4 and the lid 8 after sealing, the excess portion is removed with a cutter, a grindstone, or the like as shown in FIG. 8 (c). After that, as shown in FIG. 9, the base 9 having the attachment 9a for attaching the adherend is adhered to the lid 8 via an adhesive. As a result, the decorative article 10 with a nacre is made. Here, the adherend, although not shown, is a part of the body such as clothes, a tie, a shirt, or a finger, neck, wrist, ankle, earlobe, or hair. In this embodiment, the fixture 9a is a pin body consisting of a single pointed pin, and after passing the pin body through the adherend, it is stopped by a fastener (not shown) to be a decorative article with a nacre. 10 can be attached to the adherend.

Although not shown, instead of the lid 8, the base 9 may be used to directly cover and seal the bottom surface of the cured resin 7 covered with the encapsulation body 4 made of nacre. ..
Further, the attachment 9a for attaching the adherend may be a single screw shaft, although not shown, in addition to the above-mentioned pointed pin. In that case, a stopper is screwed to the screw shaft to make a pearl. The layered decorative article 10 can be attached to the adherend. Further, the attachment 9a for attaching the adherend may be a small ring fixed to the base. In this case, by passing a chain or a large ring through the small ring and hanging the chain around the neck, wrist, ankle, or the like, a necklace, a bracelet, anklet, or the like with a decorative article with a mother-of-pearl layer can be obtained. Further, the attachment 9a for attaching the adherend may be a holding tool such as a clip fixed to the base. In this case, by hanging or sandwiching the clip on the collar, tie, earlobe, hair, etc. of the adherend, it is possible to make a collar decoration, a tie pin of a type that sandwiches the tie, an earring, a hairpin, or the like.

The decorative article with nacre of the present invention can be used for a product that gives an aesthetic appearance to a decorative article with a design such as a badge, an accessory, a memorial item, etc., in which characters and figures are projected.
