JP 2001-295171 A

  By the way, ordinary cosmetics such as cosmetic brushes and puffs have only achieved a cosmetic effect of applying cosmetics to a limited part due to the feeling of use and usability of the applicator and the addition and subtraction of the cosmetics. . Therefore, there has been a demand for a cosmetic device that has a makeup effect on a wide body part such as the entire face, neck, body, and the like.

  The objective of this invention is providing the manufacturing method of the novel spherical cosmetics which mainly made the fiber assembly.

  Another object of the present invention is to obtain a higher cosmetic effect by making it possible to apply cosmetics to a wide range of sites.

  1st invention provides the spherical cosmetics which have the fiber assembly which has the soft and substantially spherical shape formed by converging a short fiber, and the powder cosmetics uniformly adhered to the surface of the fiber assembly. Here, it is preferable that the powder cosmetic does not exist inside except the vicinity of the surface of the fiber assembly. The density of the short fibers is preferably higher on the surface of the fiber assembly than on the center of the fiber assembly, and the short fibers on the surface of the fiber assembly are inclined along the surface.

  2nd invention provides the manufacturing method of a spherical cosmetics. This manufacturing method was formed by focusing a short fiber on the bottom part of the saucer having a first step of pouring a mixed solution in which powder cosmetics were mixed with a solvent into a saucer having an uneven bottom part. A second step of arranging the flexible fiber assembly, and a third step of impregnating the fiber assembly stored in the bottom of the tray by rolling the fiber assembly disposed on the bottom of the tray. And a fourth step of obtaining a spherical cosmetic device in which the powder cosmetic material is uniformly adhered to the surface by drying the fiber assembly impregnated with the mixed solution. Here, in a 2nd step, it is preferable that the site | part which touches the convex part provided in the bottom part of the saucer among the surfaces of a fiber assembly contacts the surface of the liquid mixture stored in the bottom part of the saucer. In the fourth step, the fiber assembly impregnated with the mixed solution may be heated.

  According to the first invention, by rubbing the spherical cosmetics against the skin, the powder cosmetics originally attached to the surface can be applied easily and with a good feeling of use. The user can also adjust freely. Thereby, while having a makeup effect also over a wide region, the powder cosmetic can be applied with nuance according to the user's preference. Moreover, according to 2nd invention, such a spherical cosmetics can be manufactured easily and at low cost.

  FIG. 1 is an explanatory view of a spherical cosmetic device according to the present embodiment, and this cosmetic device is for directly applying an eye shadow to a face as an example. In addition, the figure has shown the state which cut a part of spherical cosmetics 1 and exposed the inside.

  This spherical cosmetic tool 1 is mainly composed of a fiber assembly 2. The fiber assembly 2 is formed by, for example, converging short fibers of natural fibers, synthetic fibers, or mixed fibers thereof to form a substantially spherical shape, and has flexibility as a whole. In this embodiment, spherical absorbent cotton, that is, cotton balls, is used as the fiber assembly 2, but acrylic balls or the like may be used. On the surface of such a fiber assembly 2, for example, a powder cosmetic 3 including a pigment containing pearl or glitter is uniformly attached. The powder cosmetic 3 does not exist inside except the vicinity of the surface of the fiber assembly 2. Moreover, regarding the fiber assembly 2, the density of the short fibers is higher on the surface than on the center. Furthermore, the short fiber on the surface of the fiber assembly 2 falls along the surface without raising from the surface.

  Hereinafter, the manufacturing method of the spherical cosmetic device 1 will be described with reference to FIGS. 2 to 5. First, the liquid mixture which mixed the pearl etc. which become the powder cosmetics 3 mentioned above in the solvent is produced | generated. Specifically, a predetermined amount of pearl or the like is added to a solvent such as IPA (iso-propyl alcohol), oil, or water, and the mixture is sufficiently stirred. The pearl or the like mixed in the solvent may be a single color, but may be a plurality of colors. In some cases, other components such as paste components such as PVP may be added to the mixed solution.

  Next, as shown in FIG. 2, a predetermined amount of the mixed solution 5 generated in the previous process is poured into the tray 4 prepared in advance, and the mixed solution 5 is stored at the bottom of the tray 4. The point to be noted in this process is to gently pour the mixed solution 5 little by little so that pearls and the like are not unevenly distributed in the stored mixed solution 5. In addition, the bottom part of this saucer 4 is formed in uneven | corrugated shape, Such a structure is realizable by arrange | positioning the several wire which has a predetermined | prescribed line | wire width in a grid | lattice form (or row | line | column), for example.

  Subsequently, as shown in FIG. 3, the cotton ball 6 that becomes the fiber assembly 2 described above is disposed on the bottom of the tray 4. At this stage, the cotton ball 6 is in a state in which short fibers are raised from the surface, and its shape is irregular (however, it is spherical to some extent). Since the convex part 4a which has the height corresponded to the line | wire width of a wire is provided in the bottom part of the saucer 4, the arrange | positioned cotton ball 6 is in the state which floated from the bottom face (concave part) by this height. Retained. Of the surface of the cotton ball 6, the portion that contacts the convex portion 4 a comes into contact with the surface of the mixed solution 5 stored in the bottom of the tray 4. As described above, the reason why the cotton balls 6 and the mixed solution 5 are kept in contact with each other is because the pearl or the like is attached only to the surface of the cotton balls 6 to produce a good spherical cosmetic 1. Moreover, the reason for providing the convex portion 4 a at the bottom of the tray 4 is to secure the storage amount of the mixed liquid 5 to some extent by separating the cotton balls 6 from the bottom surface of the tray 4.

  And the cotton ball 6 arrange | positioned at the bottom part of the saucer 4 is rolled as shown in FIG. Thereby, the mixed solution 5 is impregnated from the entire surface of the cotton ball 6. The solvent in the mixed solution 5 penetrates to the inside of the cotton ball 6, whereas the particles of the pearl in the mixed solution 5 are larger than the density of the cotton ball 6. Stay in the vicinity. In this process, the surface of the cotton ball 6 impregnated with the mixed solution 5 is pressed against the bottom of the tray 4 by its own weight. Therefore, the density of the short fibers of the cotton balls 6 is higher on the surface than on the center, and the short fibers raised from the surface of the cotton balls 6 fall down along the surface. As a result, the cotton ball 6 changes to a beautiful bowl-like sphere. In addition, the speed, range, time, etc. which roll the cotton ball 6 are suitably set through a prior experiment or simulation.

  Finally, as shown in FIG. 5, the cotton balls 6 impregnated with the mixed solution 5 are dried by the dryer 7. The drying temperature (above room temperature), the drying time, and the like are set as appropriate through prior experiments and simulations. In this process, particularly when water is used as the solvent of the mixed solution 5, it is preferable to heat the cotton balls 6 with the dryer 7. This is because the softness (texture) of the cotton ball 6 can be arbitrarily adjusted by the degree of heating. Through a series of processes as described above, the spherical cosmetic 1 having the powder cosmetic 3 uniformly attached to the surface is completed.

  Thus, according to this embodiment, the powder cosmetic 3 can be applied only by rubbing the spherical cosmetic tool 1 against the skin. Therefore, since it is freed from the conventional work of scraping off the solid powder cosmetic each time, the convenience for the user can be improved. In addition, since the spherical makeup tool 1 has flexibility, the touch at the time of makeup is good, and the user can freely adjust the addition and subtraction. Therefore, even if it is used for a wide part such as the entire face, neck, body, etc., it is easy to use, and a cosmetic effect can be obtained in which lamé is scattered with a delicate nuance. Furthermore, according to such a novel spherical cosmetic 1, a fresh taste can be given to the user and a soft touch can heal the user's heart, so that a product with high product appeal can be realized.

  Moreover, according to the manufacturing method concerning this embodiment, the spherical cosmetics 1 can be manufactured easily and at low cost. Here, as a comparative example, a case where pearl or the like is attached to the cotton ball 6 by spraying will be considered. In this case, since pearls and the like are concentrated on the short fibers raised from the surface of the cotton ball 6, the uniformity of the adhesion cannot be ensured and the cotton ball 6 cannot be hatched. On the other hand, according to the present embodiment, it is possible to generate a good spherical cosmetic device 1 without causing these problems.
