Description

  The present invention relates to a doll toy, and more particularly to a doll toy whose skin tone changes according to environmental temperature or sunlight.

  Conventionally, there are various doll toys that imitate humans and animals. Among them, there is a doll toy whose color tone changes depending on the environmental temperature, and it can be immersed in hot water to enjoy the color tone change. This is realized by applying a temperature-sensitive discoloration (thermochromic) paint on the toy surface or mixing a microencapsulated thermochromic material with a resin material for molding the toy. For example, there has been proposed a doll toy molded from a molding material obtained by mixing a pink coloring pigment and a yellow thermochromic material. This toy expresses the color tone of the thermochromic material in the low temperature range and expresses the color tone of the colored pigment in the high temperature range, so when the body temperature rises due to changes in the environmental temperature, the skin changes to a reddish color, When the body temperature is lowered, it can be repeated to return to the original color (for example, see Patent Document 1).

There is also a doll toy in which the color tone of the toy changes due to the irradiation of sunlight. This uses a photochromic material whose color changes with ultraviolet rays, and a color changing toy molded with a colored synthetic resin mixed with this photochromic material has been proposed. This toy is discolored when exposed to sunlight (ultraviolet rays), and can be repeatedly returned to its original color when left in a place not exposed to sunlight (see, for example, Patent Document 2).

Head 3 is planted with hair, and facial components such as eyes, nose, lips, eyebrows, and ears are formed on the epidermis side. The eyes of the doll toy 1 according to the present embodiment are configured by forming an approximately elliptical through-hole at a desired position of the head 3 and having an eyeball mechanism on the inside that opens and closes in response to the elevation of the doll.

  The left and right arm parts 4 and 4 and the left and right leg parts 5 and 5 are made of resin and are formed in a hollow shape, like the body part 2 and the head part 3. In addition, a cylindrical joint (not shown) having the same diameter as the arm mounting hole formed in the body part 2 is formed in the base part of the arm parts 4 and 4, and a base part of the leg parts 5 and 5 is formed in the body part 2 Cylindrical joints (not shown) having substantially the same diameter as the leg mounting holes are integrally provided.

  The cylindrical joint of the body part 2 is fitted into the body part mounting hole of the head part 3, the arm parts 4 and 4 are connected to the arm part mounting hole hole of the body part 2, and the leg part mounting hole of the body part 2 The tubular joints of the leg portions 5 and 5 are respectively fitted to each other to connect the members. The head 3, the arms 4, 4 and the legs 5, 5 can be rotated with respect to the trunk 2, and the doll toy 1 can be in a sitting position as shown in FIG. 2.

  The body 2, head 3, left and right arms 4, 4 and left and right legs 5, 5 are molded into a desired shape by molding a thermochromic material and a photochromic material into a colored vinyl chloride resin. Created.

  The thermochromic material exhibits reversible decoloration by heat, and has a property of developing a predetermined color at a first temperature and becoming transparent at a second temperature. As the thermochromic material, a microencapsulated thermochromic pigment composed of three components of an electron-donating color-forming dye, an electron-accepting substance, and a solvent serving as a reaction medium of both can be used. In the present invention, the first temperature is room temperature (1 to 30 ° C., according to the Japanese Pharmacopoeia), and the second temperature is a high temperature range of 35 ° C. or higher. In this embodiment, in order to express the color of human skin, a yellow component thermochromic material is blended with a vinyl chloride resin colored with a pink color pigment. The thermochromic material is blended in the molding material in an amount of 1.0 to 5.0% by weight, preferably 2.0 to 5.0% by weight. If the blending amount is less than 1.0% by weight, the change in color tone is difficult to visually recognize, and even if blending more than 5.0% by weight, no further effect can be expected. As the thermochromic material used in the present invention, for example, chromicolor New Fast Yellow 35M (powder, colorless temperature 36 ° C.), chromicolor New Fast Yellow 37M (powder) to express the color of human skin. , Colorless temperature 41 ° C.) (both trade names, manufactured by Matsui Dye Chemical Co., Ltd.) and the like.

  The photochromic material exhibits reversible decoloration when irradiated with ultraviolet rays. As the photochromic material, a microencapsulated organic photochromic material such as a spiropyran material, a spirooxazine material, or an azobenzene material can be used. The photochromic material is blended in the molding material in an amount of 5.0 to 10.0% by weight, preferably 7.0 to 10.0% by weight. If the blending amount is less than 5.0% by weight, a change in color tone is difficult to visually recognize, and even if blending more than 10.0% by weight, no further effect can be expected. As a photochromic material used in the present invention, for example, a mixture of Photopia Yellow 2W (powder) and Photopia Purple 3W (powder) (both trade names, manufactured by Matsui Pigment Chemical Co., Ltd.) can be used. .

  The color pigment for coloring the vinyl chloride resin pink is prepared by mixing a red organic pigment with titanium oxide as a white pigment. The red organic pigment and titanium oxide are mixed at an arbitrary ratio to create a desired pink color. This pink colored pigment appears after the doll toy 1 is left under a high temperature range and the thermochromic material is colorless. The color pigment is blended in the molding material at 15% by weight or less. When the blending amount is more than 15% by weight, it is difficult to visually recognize changes in the skin tone due to the thermochromic material and the photochromic material, which is not preferable.

  In addition, a plasticizer is added to impart flexibility to the polyvinyl chloride resin, a stabilizer for preventing thermal decomposition of the vinyl chloride resin in the molding process, a dispersant for enhancing the dispersibility of the colorant and the resin, In addition, an ultraviolet inhibitor, an antioxidant, a thickener and the like can be blended without departing from the present invention.

  The above materials are kneaded to form a molding material, which is then formed into a hollow shape using a slush molding method or the like. As described above, the members are connected to each other by fitting the cylindrical joints into the mounting holes to form the doll toy 1.

  When the doll toy 1 of the present invention is immersed in a hot liquid such as hot water or hot air is applied with a dryer or the like, the thermochromic material in the molding material is discolored colorless and the color of the colored pigment appears. . Since the thermochromic material is yellow and the color pigment is pink, the skin color changes to pink when immersed in hot water in a bathroom, etc. Can be expressed. Also, if you leave it at room temperature, it will return to its original skin color, making it fun to play in the bathroom.

  And when sunlight is irradiated, since the photochromic material changes color, the skin color changes to dark. Therefore, the doll toy 1 can express a state of being tanned outdoors or near the window where the sunlight hits. Moreover, since it returns to the original skin color when it is left to stand at room temperature, this can be repeated.

  Also, as shown in FIG. 3, when exposed to sunlight with the costume 6 on, only the exposed part changes color, so that it is possible to play with a mark of sunburn. In addition, if you wear a swimsuit as a costume, or put a sticker imitating various shapes such as hearts or stars on the skin and irradiate it with sunlight, the swimsuit will follow or leave the seal pattern tanned Can do.

  In the doll toy 1 of the present embodiment, the head 3, the left and right arms 4, 4 and the left and right legs 5, 5 are rotatable with respect to the trunk 2, so that as shown in FIG. The head 3, the arm parts 4, 4 and the leg parts 5, 5 can be rotated to make the doll toy 1 take any posture.
