[Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-139820 Summary of the Invention [Problem to be solved by the invention]

[0005] The above-mentioned bead toys are provided with beads of various colors, and decorative items with colorful patterns can be made. In order to make more dazzling decorative items, this type of bead toy may require glossiness.

[0006] An object of the present invention is to provide a weldable bead toy that has a glossy appearance and is attractive. [Means for solving the problem]

[0007] The weldable bead toy according to one aspect of the present invention is a weldable bead toy formed by blending a pigment as a colorant with a water-soluble resin, and the pigment contains a gold or silver pigment. The pigments are colored and transparent spheres with a plurality of weld lines formed on the surface, and the content of the gold or silver pigment among the pigments is 45% by weight or more, and the gold or silver pigment is pearl powder. It is characterized by the following. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a weldable bead toy that has a glossy appearance and is excellent in appearance. [Brief explanation of the drawings]

[0009] [Figure 1] 1 is a front view showing the appearance of beads in a weldable bead toy according to an embodiment. FIG. [Figure 2] 1 is a table showing the formulation of various beads produced in the examples. [Figure 3] 1 is a photograph showing the appearance of metallic light blue beads produced in the examples. [Figure 4] 1 is a photograph showing the appearance of metallic black beads produced in the examples. DETAILED DESCRIPTION OF THE INVENTION

[0010] An embodiment of the present invention will be described with reference to the drawings. As shown in Fig. 1, a weldable bead toy 10 according to the embodiment is made up of spherical beads 20 with a particle size of about 5 mm. The beads 20 are made of a transparent synthetic resin, which is a water-soluble resin containing polyvinyl alcohol, and is colored by blending multiple pigments as coloring agents, and are formed by injection molding using a mold. When coloring the beads 20 with a coloring agent, the beads can be colored transparently in colors such as green, blue, red, yellow, and purple, which harmonize transparency and color.

[0011] The pigment, which is a coloring agent, contains at least one of gold and silver pearl powder. The inclusion of gold or silver pearl powder gives the beads 20 a glossy appearance and an attractive appearance. The content of gold or silver pearl powder is 45% by weight or more of the total weight of the pigment used to form the beads 20. By using such a content of pearl powder, the beads 20 can be effectively imparted with gloss.

[0012] 1, multiple weld lines 26 are formed on the surface of the beads 20 due to the injection molding process. These multiple weld lines 26 are intentionally created during the process of forming the beads 20 (for example, by slowing down the injection molding speed). The formation of multiple weld lines 26 in this way causes diffuse reflection of light on the surface of each weld line 26, resulting in beads 20 with superior gloss.

[0013] Because the beads 20 are made of a water-soluble resin, they can be arranged in contact with one another and then coated with a liquid such as water or immersed in a liquid such as water to wet their surfaces and dissolve them. The moisture on the surfaces of the beads 20 is then evaporated and the beads 20 are dried, allowing adjacent beads 20 to weld together. For this reason, for example, an illustration sheet with a desired design can be fixed to the underside of a tray, and beads 20 of a desired color to match the design are placed on the tray. Then, by wetting the beads 20 and drying them, a decorative object matching the design on the illustration sheet can be created.

[0014] Since the beads 20 have a glossy appearance, a brilliant and dazzling ornament can be realized by producing the above ornament using the beads 20. Note that the ornament may also be produced by combining the glossy beads 20 with other non-glossy beads.

[0015] As explained above, the weldable bead toy 10 according to the embodiment is formed by blending a pigment (pearl powder) containing at least one of gold and silver as a coloring agent, and as a result, the particles that provide the luster are finer, giving it a more brilliant luster and a more attractive appearance than conventional weldable bead toys, which have a poor appearance due to the coarse particles of the metal powder. Therefore, the weldable bead toy 10 exhibits an even more brilliant luster depending on the angle of the light shining on the decorative object assembled using the beads 20, allowing the user to enjoy playing with the beads without getting bored.

[0016] Although the present embodiment illustrates spherical beads 20, the shape of the beads 20 is not limited thereto. For example, other shapes such as star-shaped or polyhedral shapes are also possible. By using a polyhedral shape, the effect of surface gloss due to reflected light is enhanced, making it possible to realize more attractive and dazzling weldable beads.

[0017] According to the above-described embodiment of the present invention, it is possible to provide the following weldable bead toys.

[0018] The weldable bead toy according to the first aspect is a weldable bead toy formed by blending a pigment, which is a coloring agent, with a water-soluble resin, and the pigment contains a gold or silver pigment.

[0019] According to this configuration, the particles that provide the luster are finer than those of conventional weldable bead toys, and the luster is more brilliant, making it possible to realize a weldable bead toy that looks great.

[0020] Also, the first The weldable bead toy according to the embodiment has a plurality of weld lines formed on the surface. It is said to be a colored, transparent sphere. There are.

[0021] With this configuration, diffuse reflection of light occurs on the surface of each weld line, and the synergistic effect of including gold or silver pigments makes it possible to create a weldable bead toy with even greater gloss.

[0022] And the first In the weldable bead toy according to the third aspect, the content of the gold or silver pigment among the pigments is 45% by weight or more.

[0023] According to this configuration, the content of the gold or silver pigment is increased, so that gloss can be effectively imparted to the weldable bead toy.

[0024] Furthermore, the first In the weldable bead toy according to the third aspect, the gold or silver pigment is pearl powder.

[0025] This configuration makes it possible to provide a specific material that provides a glossy finish compared to conventional weldable bead toys.

[0026] The above-described embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments may be embodied in various other forms, and various omissions, substitutions, and modifications may be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the scope of the inventions and their equivalents as defined in the claims. [Example]

[0027] In the examples, we produced 12 glossy, weldable bead toy beads. Gold, coarse silver, and fine silver pearl powder were used to create the gloss. Figure 2 shows the amount of colorant and the pearl powder content for each color. Note that titanium dioxide, shown in Figure 2, is added to produce a white color. Gold is pearl powder with gold particles measuring 5 to 25 μm in diameter, coarse silver is pearl powder with coarse silver particles measuring 10 to 60 μm in diameter, and fine silver is pearl powder with fine silver particles measuring 5 to 25 μm in diameter. In Figure 2, the amount of each colorant is expressed in grams, and the pearl powder content, i.e., the amount of gold, coarse silver, and fine silver in the total colorant, is expressed in weight percent.

[0028] To produce the beads, first, each colorant, including pearl powder, was dissolved in a mixture of PVA (polyvinyl alcohol) as a solvent, a small amount of glycerin, and a small amount of stearic acid. Next, the solution was poured into a mold, and spherical beads were molded by injection molding. After injection molding, the molded product was separated from the runner of the mold and temporarily stored in a place that was shielded from ultraviolet light. Note that during injection molding, the solution was poured into the mold and injected at a speed slower than standard, so as to intentionally form multiple weld lines on the surface of the beads.

[0029] The injection molding conditions are a molding temperature of 175 to 190°C and an injection pressure of 30 to 100 kgf / cm. 2 (or MPa). The injection speed was in the range of 25 to 40 mm / sec, and the molding cycle was 28 seconds / shot. Cold water was used as cooling water. These conditions were compared with the conditions for producing non-glossy beads of similar color, with the molding temperature being about 5°C higher and the injection pressure being 5 kgf / cm. 2 The pressure was set to a high level, the injection speed was set to a slow level of about 5 mm / sec, and the molding cycle was set to a slow level of about 2 to 3 seconds / shot.

[0030] The surfaces of the 12 colored beads produced were visually observed. Figure 3 shows a photograph of the appearance of the metallic light blue (light blue) beads, and Figure 4 shows a photograph of the appearance of the metallic black (black) beads. As shown in Figures 3 and 4, weld lines (the black striped areas in the photographs) were observed on the surface of both beads, and they also had a glossy appearance. In this way, multiple weld lines were confirmed on the surface of all the beads produced, and it was also confirmed that they had a glossy appearance. [Explanation of symbols]
