  And the slurry-like thing from which a color differs mutually is obtained by changing the color of the said inorganic pigment and an organic pigment.

  In the filling step, the slurry materials having different colors prepared in the previous preparation step are filled using a filling machine so as to form a multicolor pattern in a container such as a compact. This filling machine includes a nozzle assembly support as a manufacturing tool provided with a nozzle for discharging a slurry-like material. Hereinafter, the nozzle assembly support and the filling machine will be described.

  As shown in FIG. 1, the nozzle set support 11 has a disk-shaped main body 12, and a nozzle set 10 of the first nozzle 3 and the second nozzle 4 penetrating the main body 12 is provided in the main body 12. It has multiple sets. Two or more second nozzles 4 of the nozzle set 10 are arranged in an annular position around the first nozzle 3 of the same set. In particular, in the present embodiment, in the plurality of sets of the nozzle set support 11, the second nozzle 4 has a smaller diameter than that of the first nozzle 3, and these plural sets have three identical second nozzles 4. The number of the second nozzles 4 in the same set is arranged around the first nozzle 3 so as to surround the first nozzle 3 in the same set.

  A first extruder is connected to the first nozzle 3 via a first tube, and a second extruder is connected to the second nozzle 4 via a second tube.

  These first and second extruders respectively extrude the slurry-like material filled therein into the first and second nozzles 3 and 4 through the first and second tubes, respectively. 4, the discharge pressure, the discharge timing, and the discharge period can be adjusted.

  In the filling process using the filling machine having such a configuration, the first and second extruders are filled with the slurry-like materials having different colors prepared in the previous preparation process. Here, the first extruder is filled with a slurry of one color, and the second extruder is filled with a slurry of a different color from the one.

  Next, the extruder is operated to discharge the slurry of one color from the first nozzle 3 and fill the container 7 (see FIG. 2), and the slurry of different color from the second nozzle 4 is different from the one color. Is discharged to fill the container 7.

  Then, as a subsequent process of this filling process, the slurry-like material in the container 7 is compression-molded by, for example, pressing it with a press machine, for example, through a filter paper or a nonwoven fabric, and the solvent is removed by drying. 2 is obtained.

  The multicolor powder cosmetic shown in FIG. 2 corresponds to the first nozzle 3 (compressed and dried slurry-like material discharged from the first nozzle 3), and the second nozzle 4 is a multicolor powder cosmetic with a firework pattern, including a powder cosmetic B having a different color from the one color corresponding to 4. More specifically, the pattern of the one color powder cosmetic A extending radially from the position corresponding to the first nozzle 3 and the radial portion of the one color pattern are filled and the one color of the one color is filled. A multicolor powder cosmetic comprising a pattern made of different color powder cosmetic B surrounded by a pattern.

  The slurry-like materials discharged from the first nozzle 3 are not limited to the same color, and may be all different colors, or may be a combination of the same color and different colors such as red, red, and green. Moreover, the color of the slurry-like material discharged from the second nozzle 4 may be different from that of the slurry-like material discharged from the same set of the first nozzles 3.

  Further, in the filling step, by adjusting one or more of the discharge pressure, the discharge timing, and the discharge period of the first and second nozzles 3 and 4, even when the nozzle assembly support 11 is used, the pattern other than the pattern shown in FIG. Complex patterns, fine patterns, and unprecedented patterns can be easily obtained.

  As described above, in the present embodiment, the nozzle set support 11 including a plurality of sets 10 including the first nozzle 3 and the two or more second nozzles 4 arranged around the first nozzle 3 is used. Since the slurry-like material different in color from the slurry-like materials ejected from the first nozzle 3 of the same set is ejected from the second nozzle 4, manufacturing by using a partition or using a partition without using a partition is possible. Complex patterns, fine patterns, and patterns that are difficult to form with the use of nozzles can be easily formed to meet the various demands of consumers.

  Further, in the present embodiment, the second nozzle 4 has a smaller diameter than the first nozzle 3 in the plurality of sets of the nozzle set support 11, and the plurality of sets are the same set of the second nozzle 4. And three or more second nozzles 4 of the same set are arranged around the first nozzle 3 so as to surround the first nozzle 3 of the same set. In addition, complicated patterns, fine patterns, and patterns that have not existed before are easily formed.

  Next, in addition to the powder cosmetics A and B, when obtaining a multicolor powder cosmetic containing the ground color (base color) powder cosmetic C in the container 7, the container 7 is used as a pre-process of the filling step. In addition, a slurry-like material having a ground color different from the slurry-like material from the first and second nozzles 3 and 4 is filled in the whole. Next, in the same manner as described above, a filling process using the nozzle assembly support 11 is performed, and a post process is performed.

  With this manufacturing method, for example, as shown in FIG. 3, a ground color powder cosmetic C and powder cosmetics A and B of different colors filled from the first and second nozzles 3 and 4 are provided. Since a multi-colored powder cosmetic with a patterned pattern is obtained and a pattern based on the ground color is added in this way, a wider variety of patterns can be obtained. Here, for example, by increasing the discharge pressure of the first and second nozzles 3 and 4 so that the slurry-like material from the first and second nozzles 3 and 4 reaches the bottom of the container 7, Even if the pattern of the powder cosmetics A and B is formed up to the bottom of the container 7, for example, the ground color remains at the bottom of the container 7 by reducing the discharge pressure of the first and second nozzles 3 and 4. You may do it.
