Namely, in the present invention, a silicone elastomer accessory is formed by compression molding, which comprises the first step of forming a continuous concavity on a silicone elastomer accessory body; the second step of embedding a silicone elastomer layer containing fine titanium powder into said continuous concavity; the third step of separately forming a silicone elastomer decorative continuous protrusion; and the fourth step of placing the accessory body obtained in the second step on said decorative continuous protrusion and curing with heat for integration.
Further, an alternative method of the present invention can comprise first the step of forming a silicone elastomer decorative continuous protrusion, which corresponds to the abovementioned third step, the step of placing the silicone elastomer body on the obtained decorative continuous protrusion for integration, which corresponds to the abovementioned fourth step, and then the step of coating a part of the silicone elastomer body with a silicone elastomer solvent solution mixed with fine titanium powder in a belt-like fashion. However, when the layer containing fine titanium powder is provided by this coating method, it is difficult to precisely control the coating area, and moreover, the coated layer may peel off resulting from abrasion, which results in poor durability as compared to the product by the abovementioned method. However, there is no difference in action and effectiveness of the resulting products between the abovementioned compression method and the coating method. - A silicone elastomer to be used in the present invention is not particularly limited and any organic silicon polymer having a siloxane bond can be used as long as it has rubber-like properties.

For example, minerals such as rutile, brookite, and octahedrite can be used. Further, as titanium alloy powders, powders of alloys of titanium with metals such as copper, tin, iron, aluminium, chromium, cobalt, molybdenum, and tungsten can be used. Examples of the powders of titanium alloys include powders of Ti-Al, Ti-V, Ti-Mo, Ti-Cr, Ti-Mn, Ti-Fe, Ti-Al-Cr, and Ti-Cr-Fe-O; the composition ratio of each alloy powder can be appropriately selected.
- Further, powders of titanium compounds can be used, which include powders of hydrides such as TiH2 and TiH4; oxides such as TiO, Ti2O3, TiO2, Ti(OH)2, Ti(OH)3, and M2TiO3 (M is a metal atom); sulfides such as TiS, Ti2S3, and TiS2; oxyacid salts such as Ti2(SO4)3, Ti(SO4)2, and TiP2O7; boron compounds such as Ti2B, TiB, TiB2, and Ti2B5; titanium carbide composed of(TiC); silicone compounds such as TiSi2, TiSi, and Ti5Si3; nitrides such as TiN, Ti3N4, Ti3N6, and Ti5N6; phosphorus compounds such as TiPn; titanium halides such as TiCl2, TiCl3, TiCl4, TiBr2, TiBr3, TiBr4, TiI2, TiI3, and TiI4; complex salts such as M2TiF5, M3TiF6, M2TiF6, M2 [TiCl5 (OH)2], M2TiCl6, [Ti(OH)6]Cl3, and M2[TiBr6]; and titanates such as CaTiO3, SrTiO3, BaTiO3, CdTiO3, and PbTiO3. These powders can be used alone or in combination.
- In the present invention, a body accessory which is suitable for the characteristics of silicone elastomer can be formed into various products which include ornamental accessories such as necklaces, wristbands, and hair bands. In particular, it is effectively used for wristbands, necklaces, and bracelets to relax nerves and muscle of athletes.
- A body accessory of the present invention will be explained by referring to drawings.
Fig. 1 is a perspective view of an example of abody accessory 1 of the present invention. Fig. 2 is a sectional view taken on line A-A of Fig. 1, and Fig. 3 is a cross-sectional view taken on line B-B of Fig. 1.
The body accessory of the present invention comprises anaccessory body 8, a joint for hooking (small hole) 2, a joint for hooking (small ball) 3, and an indicatingpart 5. On theaccessory body 8, a decorativecontinuous protrusion 7 is formed on the surface side and a layer containing titanium powder is formed on the back side.
Use of silicone elastomer as a forming material provides decorativeness and soft feeling to the body and use of the abovementioned fine titanium powder as a major component provides physiological actions such as blood circulation promotion and an electromagnetic action by metallic titanium, which make it possible to obtain a body accessory providing improved health promoting functions more stably for a longer period of time as compared to conventional body accessories. The product of the present invention provides greater functions as compared to conventional body accessories making the best use of the characteristics of metallic titanium such as physiological actions, for example blood circulation promotion and an electromagnetic action. These actions of titanium are effective without direct contact of titanium with the skin and generated relatively fast and the effectiveness lasts for a long period of time to provide marked health promoting effects. - The process of the production according to the present invention will be explained based on an example. However, the scope of the present invention is not limited to this example.
- As mentioned above, the body accessory of the present invention can be manufactured by extrusion molding, injection molding, and compression molding. As one example of the molding methods, a process of manufacturing using compression molding is explained in detail referring to Fig. 4 to Fig. 9.
First, in the first step as shown in Fig. 4, a silicone elastomer material to form the accessory body of the present invention is placed in the concave part of thelower mold 9 and theupper mold 10 having the firstupper part 14 and the secondupper part 15 is pressed down onto the first lower mold, cure molding is carried out by pressing with heat to form theaccessory body 8 as shown in Fig. 5. In this way, theconcave part 6 of theaccessory body 8 is formed by the secondupper part 15 of the upper mold. Next, in the second step as shown in Figure 6, a silicone elastomer material containing titanium powder is embedded into theconcave part 6 of theaccessory body 8 placed in the same first lower mold and pressed with heat. After pressing with heat, as shown in Fig. 7, theaccessory body 8 in which a silicone elastomer material layer containing titanium powder is formed in theconcave part 6 is obtained. The silicone elastomer material layer containing titanium powder can be either continuous or discontinuous lengthwise as shown in Fig. 1. Further, in the third step as shown in Fig. 8, theconcave part 18 corresponding to the decorativecontinuous protrusion 7 of the accessory is provided in the second lower mold and the uncured silicone elastomer is embedded here, after which the secondupper mold 13 with the upperconvex part 17 formed is pressed down onto the secondlower mold 12 to form the decorativecontinuous protrusion 7. In such a state, as shown in Fig. 9, the accessory body in which the silicone elastomer layer containing titanium powder is embedded into the concave part obtained by the second step is placed and the secondupper mold 13 having the upperconvex part 17 is pressed down onto the secondlower mold 12 to form the projected accessory of the present invention. Favorably, the color of the decorativecontinuous protrusion 7 is different from that of theaccessory body 8 for improved decorativeness. For example, if theaccessory body 8 is black, the color of the decorativecontinuous protrusion 7 can be yellow or red to increase the distinguishability of the product. - As shown in Fig. 10, the accessory thus obtained has the
layer containing titanium 4 on one side (the side in contact with the skin) and the decorativecontinuous protrusion 7 on the other side (the exterior side). The silicone elastomer layer containingtitanium powder 4 can be either discontinuous as shown in Fig. 1 or continuous.
Further, as mentioned above, the alternative method can comprise the step of first forming a silicone elastomer decorative continuous protrusion, which corresponds to the abovementioned third step; the step of placing the silicone elastomer body on the obtained decorative continuous protrusion for integration, which corresponds to the abovementioned fourth step; and then the step of coating a part of the silicone elastomer body with a silicone elastomer solvent solution mixed with fine titanium powder in a belt-like fashion. However, the process of this method is complicated and the resulting product is not satisfactorily durable.
