Description

本発明は、たとえば、数珠やネックレスなどに利用される樹脂成形された装飾玉に関する。   The present invention relates to a resin-molded decorative ball used for, for example, a rosary or a necklace.

たとえば、数珠やネックレスなどに使用される装飾玉の製造方法として、円筒状の基礎材の端面を凸球面状とし、この凸球部分に文字または絵等を印刷し、印刷部分にアクリル樹脂等の透明樹脂を重合したものを球状に研削、研磨する方法が既に提案されている(たとえば、特許文献1参照)。
すなわち、この製造方法によると、印刷が透明樹脂によって被覆されているので、印刷が磨耗によって消失したりせず、また、透明樹脂部分も球面になっているので、透明樹脂部分がレンズの働きをして印刷が大きく浮きでたように見えるという効果がある。
For example, as a method of manufacturing a decorative ball used for beads, necklaces, etc., the end surface of a cylindrical base material is a convex spherical surface, characters or pictures are printed on the convex spherical portion, and acrylic resin or the like is printed on the printed portion. There has already been proposed a method of grinding and polishing a polymer obtained by polymerizing a transparent resin into a spherical shape (for example, see Patent Document 1).
That is, according to this manufacturing method, since the printing is covered with the transparent resin, the printing does not disappear due to wear, and the transparent resin portion is also spherical, so that the transparent resin portion functions as a lens. As a result, there is an effect that the print appears to be greatly floated.
