[0011] Hereinafter, each embodiment of the present disclosure will be described with reference to the accompanying drawings. Note that, regarding the description of the specification and the drawings according to each embodiment, components having substantially the same or corresponding functional configurations may be given the same reference numerals, and overlapping descriptions may be omitted. In addition, for ease of understanding, the scales of the respective parts in the drawings may be different from the actual ones. In directions such as parallel, right angle, orthogonal, horizontal, vertical, up and down, left and right, etc., a deviation that does not impair the effects of the embodiment is allowed. The shape of the corner is not limited to a right angle and may be rounded in an arc shape. Parallel, right angle, orthogonal, horizontal, and vertical may include substantially parallel, substantially right angle, substantially orthogonal, substantially horizontal, and substantially vertical.

[0012] Note that, in the figure, an XYZ orthogonal coordinate system may be set for convenience of explanation. Regarding the coordinate axis perpendicular to the paper surface of the drawing, a cross mark in the circle of the coordinate axis indicates that the back direction with respect to the paper surface is positive, and a black dot mark in the circle indicates that the front side with respect to the paper surface is positive. However, the said coordinate system is defined for the purpose of explanation and does not limit the posture of the cosmetic manufacturing apparatus 1 according to the present embodiment.

[0013] The X-axis and Y-axis of the XYZ orthogonal coordinate system are axes parallel to the mounting surface 21A of the base 21 of the horizontal moving device 20. That is, the plane parallel to the X-axis and Y-axis is a horizontal plane. The Z-axis is an axis perpendicular to the mounting surface 21A of the base 21 of the horizontal moving device 20.

[0014] <<Cosmetic Manufacturing Apparatus 1>> FIG. 1 is a schematic configuration diagram of the cosmetic manufacturing apparatus 1 according to the present embodiment. The cosmetic manufacturing apparatus 1 is a manufacturing apparatus for manufacturing a multi-color three-dimensional solid cosmetic. The cosmetic manufacturing apparatus 1 includes a cosmetic discharging device 10, a horizontal moving device 20, and a control device 30. A mold 100 is placed on the horizontal moving device 20.

[0015] <Cosmetic discharging device 10> The cosmetic discharging device 10 fills a predetermined cosmetic into the mold 100. The cosmetic discharging device 10 includes a plurality of cosmetic discharging parts 11 according to the type of cosmetic to be filled. The cosmetic discharging device 10 according to the present embodiment includes cosmetic discharging parts 11a, 11b, 11c, 11d, and 11e. When it is not necessary to distinguish each of the cosmetic discharging parts 11a, 11b, 11c, 11d, and 11e, each of the cosmetic discharging parts 11a, 11b, 11c, 11d, and 11e may be collectively referred to as the cosmetic discharging part 11.

[0016] The cosmetic manufacturing device 1 according to the present embodiment uses five colors of cosmetics. Therefore, the cosmetic discharging device 10 includes five cosmetic discharging parts 11. Specifically, the cosmetic discharging parts 11a, 11b, 11c, 11d, and 11e discharge yellow, white, red, pink, and green cosmetics, respectively, and fill the concave part 100a.

[0017] Note that the colors used in the cosmetic manufacturing device 1 are not limited to the above. For example, colors such as blue, purple, yellow - green, loess color, or orange can be appropriately selected. Also, the combination of colors used in the cosmetic manufacturing device 1 is not limited to the above and can be appropriately selected. Also, the number of colors is not limited to five, and a plurality of arbitrary numbers can be selected.

[0018] [Cosmetic discharging part 11] In the cosmetic manufacturing device 1, since each of the cosmetic discharging parts 11a, 11b, 11c, 11d, and 11e has the same structure, the cosmetic discharging part 11 will be described. The cosmetic discharging part 11 is a so - called dispenser that fills a liquid fluid. Note that in the cosmetic manufacturing device 1, the cosmetic discharging parts 11a, 11b, 11c, 11d, and 11e are not limited to having the same structure, and different - structured cosmetic discharging parts may be combined for the cosmetic discharging parts 11a, 11b, 11c, 11d, and 11e.

[0019] Figure 2 is a schematic diagram of the cosmetic material discharge unit 11 of the cosmetic manufacturing apparatus 1 according to the present embodiment. The cosmetic material discharge unit 11 includes a storage unit 12 and a discharge unit 15. The storage unit 12 stores the liquid cosmetic material raw material C0. Then, the storage unit 12 supplies the cosmetic material raw material C0 to the discharge unit 15. The discharge unit 15 discharges the cosmetic material raw material C0 supplied from the storage unit 12 as droplets D.

[0020] (Storage unit 12) The storage unit 12 includes a barrel 13 and a pressurizing unit 14. The barrel 13 stores the cosmetic material raw material C0. The barrel 13 is formed of, for example, a metal such as stainless steel or a resin. When the cosmetic material raw material C0 is a melt-cooling solidification type cosmetic, the barrel 13 may be made of a metal such as stainless steel and heated and kept warm. Further, the barrel 13 may be provided with a stirring blade for stirring inside.

[0021] Note that the size of the storage unit 12 may be different among the cosmetic material discharge units 11a, 11b, 11c, 11d, and 11e. For example, the storage unit 12 of the cosmetic material discharge unit 11 for a color that is frequently used may be made larger than the storage unit 12 of the cosmetic material discharge unit 11 for other colors. Also, the storage unit 12 of the cosmetic material discharge unit 11 for a color with relatively low usage may be made smaller than the storage unit 12 of the cosmetic material discharge unit 11 for other colors. By changing the size of the storage unit 12 of the cosmetic material discharge unit 11 according to the usage amount of the color, for example, it is possible to prevent the raw material of the cosmetic from being held in the storage unit 12 for a long period.

[0022] Further, a partition may be provided so that a plurality of cosmetic material raw materials of different colors can be stored in the storage unit 12. By storing a plurality of cosmetic material raw materials of different colors in the storage unit 12 and merging them at the discharge unit 15, a marble-patterned cosmetic can be generated. Also, when merging at the discharge unit 15, the blending ratio of the colors may be adjusted by adjusting the blending amount of each of the plurality of cosmetic material raw materials.

[0023] The pressurizing unit 14 supplies compressed gas to the barrel 13. When the pressurizing unit 14 pressurizes the barrel 13 with gas, the cosmetic raw material C0 inside the barrel 13 is supplied to the discharge unit 15. Note that, for example, air may be used as the gas. Further, when the cosmetic raw material discolors upon contact with air, an inert gas such as nitrogen may be used. Also, the pressurizing unit that supplies compressed gas may be constituted by a piston and a drive mechanism that drives the piston.

[0024] (Discharge unit 15) The discharge unit 15 discharges the cosmetic raw material C0 supplied from the storage unit 12 downward. The discharge unit 15 includes a nozzle 16, a rod 17, and a drive unit 18.

[0025] The nozzle 16 discharges the cosmetic raw material C0 as droplets D from the discharge port 16a. The nozzle 16 has a pipe portion 16b and a tapered portion 16c above the discharge port 16a. The rod 17 is inserted into the tapered portion 16c.

[0026] The rod 17 moves in the vertical direction by the drive unit 18. When the rod 17 moves upward, the cosmetic raw material C0 supplied from the storage unit 12 fills the pipe portion 16b. Then, when the rod 17 moves downward, the cosmetic raw material C0 inside the pipe portion 16b is discharged as droplets D from the discharge port 16a.

[0027] The amount of the cosmetic raw material C0 discharged from the cosmetic discharge unit 11 can be adjusted by the number of movements of the rod 17 or the like. The number of movements of the rod 17 or the like is controlled by the control device 30.

[0028] Note that a plurality of storage units 12 storing cosmetic raw materials of different colors may be connected to the discharge unit 15 and merged at the discharge unit 15 to generate a marble-patterned cosmetic. Also, when merging the cosmetic raw materials at the discharge unit 15, the blending amount of the cosmetic raw materials may be adjusted to adjust the blending ratio of the colors.

[0029] <Horizontal movement device 20> The horizontal movement device 20 moves the cosmetic discharging device 10 in the horizontal direction, specifically, in the X-axis direction and the Y-axis direction. The horizontal movement device 20 includes a base 21, columns 22 and 23 erected perpendicular to the base 21, and a beam 24 connecting between the columns 22 and 23.

[0030] The columns 22 and 23 are at the same position in the Y-axis direction and are provided spaced apart in the X-axis direction. The columns 22 and 23 are movable in the Y-axis direction on the base 21. The positions of the columns 22 and 23 in the Y-axis direction are controlled by the control device 30.

[0031] Further, the beam 24 includes a mounting portion movable in the X-axis direction. By mounting the cosmetic discharging device 10 on the mounting portion, the cosmetic discharging device 10 is movable in the X-axis direction along the beam 24. The position of the cosmetic discharging device 10 in the X-axis direction is controlled by the control device 30.

[0032] The horizontal movement device 20 can relatively move the position of the cosmetic discharging device 10 in the X-axis direction and the Y-axis direction with respect to the base 21 by the columns 22 and 23 moving in the Y-axis direction and the cosmetic discharging device 10 moving in the X-axis direction by the beam 24. Note that, to relatively move the position of the cosmetic discharging device 10 in the X-axis direction and the Y-axis direction with respect to the base 21, the cosmetic discharging device 10 may be fixed and the base 21 may be moved, or both the cosmetic discharging device 10 and the base 21 may be moved.

[0033] A mold 100 is placed on the placement surface 21A of the base 21. Therefore, the horizontal movement device 20 can relatively move the position of the cosmetic discharging device 10 in the X-axis direction and the Y-axis direction with respect to the mold 100.

[0034] Note that the X-axis direction is an example of the first direction, and the Y-axis direction is an example of the second direction.

[0035] <Control device 30> The control device 30 controls the cosmetic discharge device 10 and the horizontal movement device 20. The control device 30 is, for example, a personal computer or a programmable logic controller or the like. The control device 30 is communicably connected to each of the cosmetic discharge device 10 and the horizontal movement device 20.

[0036] The control device 30 controls the cosmetic discharge device 10 so as to select any one of the cosmetic discharge parts 11a, 11b, 11c, 11d, and 11e. Then, the control device 30 controls the cosmetic discharge device 10 so as to discharge a predetermined amount of cosmetic from any one of the selected cosmetic discharge parts 11a, 11b, 11c, 11d, and 11e.

[0037] Also, the control device 30 controls the horizontal movement device 20 so that any one of the cosmetic discharge parts 11a, 11b, 11c, 11d, and 11e from which the cosmetic is to be discharged is at a predetermined position with respect to the mold 100. Specifically, the control device 30 controls the horizontal movement device 20 so that the cosmetic discharged from any one of the cosmetic discharge parts 11a, 11b, 11c, 11d, and 11e to be discharged is directly above the recess of the mold 100 to be filled.

[0038] Furthermore, for each of the recesses 100a, the control device 30 stores the position, the type (color) of the cosmetic to be filled, and the amount of the cosmetic to be filled, as a database. The control device 30 can recognize the position of each of the recesses 100a and can be programmed to fill the filling amount corresponding to each of the recesses 100a.

[0039] <Mold 100> Next, the mold 100 into which the cosmetic is filled will be described. FIG. 3 is a top view of a mold 100 which is an example of a mold used in the cosmetic manufacturing apparatus 1 according to the present embodiment. FIG. 4 is a cross-sectional view of a mold 100 which is an example of a mold used in the cosmetic manufacturing apparatus according to the present embodiment. Note that FIG. 4 is a cross-sectional view taken along the line I-I of FIG. 3. Also, since the following cross-sectional views of the present disclosure are cross-sectional views cut at the same position as or corresponding to FIG. 3, the cutting lines are omitted.

[0040] The mold 100 is a mold for forming the three-dimensional shape of cosmetics. The cosmetics produced by the cosmetics manufacturing apparatus 1 according to the present embodiment have a plurality of convex portions. Therefore, a plurality of concave portions are formed in the mold 100 corresponding to the convex portions. The mold 100 is formed, for example, by taking the shape of the cosmetics to be produced. Further, the mold 100 may be formed by, for example, a three-dimensional printer.

[0041] The mold 100 is formed of, for example, silicone rubber. Note that the material of the mold 100 is not limited to silicone rubber, and may be formed of, for example, rubber other than silicone rubber, metal, resin, or the like.

[0042] The mold 100 has a plurality of concave portions 100a. In each of the concave portions 100a, a cosmetic material of a predetermined color, which is a raw material of the cosmetic material for forming the convex portion of the cosmetics corresponding to each of the concave portions 100a, is discharged from the cosmetic material discharge portion 11 and filled.

[0043] Note that the shape of the mold 100 shown in FIGS. 3 and 4 is an example, and the shape of the cosmetic material having a plurality of convex portions and the shape of the corresponding mold can be changed to a desired shape.

[0044] ≪Cosmetics Manufacturing Method Using the Cosmetics Manufacturing Apparatus 1≫ Next, a cosmetics manufacturing method using the cosmetics manufacturing apparatus 1 will be described. FIG. 5 is a flowchart of the cosmetics manufacturing method using the cosmetics manufacturing apparatus 1 according to the present embodiment. Also, a case where cosmetics are produced using a melt-cooling-solidifying type cosmetic material will be described.

[0045] First, the mold 100 is prepared (step S10, step of preparing the mold). The mold 100 includes a plurality of concave portions 100a.

[0046] Next, the cosmetic discharge unit 11a fills the predetermined concave portion 100a of the mold 100 with a yellow cosmetic. First, preparations are made so that the cosmetic discharge unit 11a can discharge the cosmetic (step S22). For example, the control device 30 stirs or heats the cosmetic inside the storage unit of the cosmetic discharge unit 11a.

[0047] Then, the control device 30 controls the horizontal movement device 20 to move the cosmetic discharge unit 11a to the concave portion 100a (step S24). After moving the cosmetic discharge unit 11a to the concave portion 100a, a predetermined amount of yellow cosmetic is filled into the concave portion 100a (step S26). When filling the concave portion 100a with the cosmetic, the amount of the cosmetic is filled so that it does not leak from the concave portion 100a to other concave portions 100a.

[0048] Then, it is determined whether filling has been completed for all the concave portions of the same color (step S28). If filling has not been completed for all the concave portions of the same color (No in step S28), the process returns to step S24 and is repeated. If filling has been completed for all the concave portions of the same color (Yes in step S28), the process proceeds to step S30.

[0049] When filling has been completed for all the concave portions corresponding to the cosmetic of the same color, here yellow (Yes in step S28), it is determined whether filling has been completed for all the predetermined colors to be filled (step S30).

[0050] If there is still a color to be filled (No in step S30), the process returns to step S22 and is repeated.

[0051] The state of filling the concave portion 100a with the cosmetic for each color (a total of four colors: yellow, white, red, and pink) is shown.

[0052] (First color (yellow)) First, the cosmetic discharge unit 11a fills the predetermined concave portion 100a of the mold 100 with a yellow cosmetic. Preparations are made so that the cosmetic discharge unit 11a can discharge the cosmetic (step S22). For example, the control device 30 stirs or heats the cosmetic inside the storage unit of the cosmetic discharge unit 11a.

[0053] Figures 6 and 7 are diagrams for explaining the operation of filling a yellow cosmetic using the cosmetic manufacturing apparatus 1 according to the present embodiment. Figures 6 and 7 are diagrams showing the state in which the cosmetic discharge unit 11a is operated. Figure 6 is a top view of the mold seen from above. Figure 7 is a cross-sectional view of the mold cut along the same cross-section as in Figure 3.

[0054] By executing step S24, the control device 30 moves the cosmetic discharge unit 11a from one circle mark to the next circle mark along the arrow A1 in Figure 6. Then, the control device 30 stops the cosmetic discharge unit 11a at the position indicated by the circle mark of the arrow A1 in Figure 6, and by executing step S26, discharges the cosmetic to fill the recess 100a with the cosmetic. Then, the steps of S24 and S26 are repeated for the recesses 100a corresponding to the same color (yellow) cosmetic.

[0055] (Second color (white)) Next, the cosmetic discharge unit 11b fills a predetermined recess 100a of the mold 100 with white cosmetic. First, preparations are made so that the cosmetic discharge unit 11b can discharge the cosmetic (step S22). Then, the steps of S24 and S26 are repeated.

[0056] Figures 8 and 9 are diagrams for explaining the operation of filling a white cosmetic using the cosmetic manufacturing apparatus 1 according to the present embodiment. Figures 8 and 9 are diagrams showing the state in which the cosmetic discharge unit 11b is operated. Figure 8 is a top view of the mold seen from above. Figure 9 is a cross-sectional view of the mold cut along the same cross-section as in Figure 3.

[0057] By executing step S24, the control device 30 moves the cosmetic discharge unit 11b from one circle mark to the next circle mark along the arrow A2 in Figure 8. Then, the control device 30 stops the cosmetic discharge unit 11b at the position indicated by the circle mark of the arrow A1 in Figure 8, and by executing step S26, discharges the cosmetic to fill the recess 100a with the cosmetic. Then, the steps of S24 and S26 are repeated for the recesses 100a corresponding to the same color (white) cosmetic.

[0058] (Third color (red)) Next, the cosmetic discharge unit 11c fills the predetermined concave portion 100a of the mold 100 with a red cosmetic. First, preparations are made so that the cosmetic discharge unit 11c can discharge the cosmetic (step S22). Then, the steps of steps S24 and S26 are repeated.

[0059] FIG. 10 is a diagram for explaining the operation of filling a red cosmetic using the cosmetic manufacturing apparatus 1 according to the present embodiment. FIG. 10 is a diagram showing a state in which the cosmetic discharge unit 11c is operating. FIG. 10 is a top view of the mold as seen from above.

[0060] The control device 30 moves the cosmetic discharge unit 11c from the circle mark to the next circle mark along the arrow A3 in FIG. 10 by executing step S24. Then, the control device 30 stops the cosmetic discharge unit 11c at the position indicated by the circle mark of the arrow A3 in FIG. 10, and discharges the cosmetic by executing step S26 to fill the concave portion 100a with the cosmetic. Then, the steps of steps S24 and S26 are repeated for the concave portions 100a corresponding to the same color (red) cosmetic.

[0061] (Fourth color (peach)) Next, the cosmetic discharge unit 11d fills the predetermined concave portion 100a of the mold 100 with a peach cosmetic. First, preparations are made so that the cosmetic discharge unit 11d can discharge the cosmetic (step S22). Then, the steps of steps S24 and S26 are repeated.

[0062] FIGS. 11 and 12 are diagrams for explaining the operation of filling a peach cosmetic using the cosmetic manufacturing apparatus 1 according to the present embodiment. FIGS. 11 and 12 are diagrams showing a state in which the cosmetic discharge unit 11d is operating. FIG. 11 is a top view of the mold as seen from above. FIG. 12 is a cross-sectional view of the mold cut along the same cut surface as FIG. 3.

[0063] By executing step S24, the control device 30 moves the cosmetic discharge unit 11d from one circled mark to the next along arrow A4 in FIG. 11. Then, the control device 30 stops the cosmetic discharge unit 11d at the position indicated by the circled mark of arrow A4 in FIG. 11, and by executing step S26, discharges the cosmetic to fill the recess 100a with the cosmetic. Then, the steps of S24 and S26 are repeated for the recesses 100a corresponding to the same color (peach-colored) cosmetic.

[0064] In step S30, when the filling of all colors is completed (Yes in step S30), the entire mold is filled with the cosmetic (step S40). Here, the entire mold 100 is filled with green cosmetic by the cosmetic discharge unit 11e.

[0065] Note that the loop from step S22 to step S30 may be collectively referred to as step S20. Step S20 is an example of a process of filling each of a plurality of recesses with a cosmetic raw material.

[0066] Note that the order of the colors discharged and filled into the recesses 100a of the mold 100 can be arbitrarily selected. For example, the cosmetic of the color to be filled into the recesses may be discharged and filled in descending order of the height of the convex portions. Also, the cosmetic of the color to be filled into the recesses may be discharged and filled in descending order of the amount of the cosmetic to be filled. Further, depending on the type of raw material, the cosmetic of the color to be filled into the recesses may be discharged and filled in descending order of the slower curing rate.

[0067] When the control device 30 moves the cosmetic discharge device 10 with the horizontal movement device 20, it can perform movement control so that the overall movement distance becomes the shortest distance. By performing control such that the movement distance is the shortest and the energy required for movement is reduced, for example, using artificial intelligence or the like, the control device 30 can efficiently control the horizontal movement device 20.

[0068] Figs. 13 and 14 are diagrams for explaining the operation of filling the entire mold 100 with cosmetic material using the cosmetic manufacturing apparatus 1 according to the present embodiment. Figs. 13 and 14 are diagrams showing a state in which the cosmetic material discharge unit 11e is operated. Fig. 13 is a top view of the mold as seen from above. Fig. 14 is a cross-sectional view of the mold cut along the same cross-section as Fig. 3.

[0069] The control device 30 moves the cosmetic material discharge unit 11e to the approximate center of the mold 100. Then, the control device 30 discharges the cosmetic material to fill the entire mold 100 with the cosmetic material. By filling the entire mold 100 with the cosmetic material, the cosmetic material is further filled on top of the cosmetic material filled in each of the recesses 100a of the mold 100. Note that the entire mold 100 may be filled with the cosmetic material while moving the cosmetic material discharge unit 11a.

[0070] Then, the control device 30 cures the cosmetic material (step S50). For example, when using a melt-cooling solidification type cosmetic material raw material, the temperature is lowered to cure the cosmetic material. Also, for example, in the case of a wet molding type cosmetic material raw material (slurry), it is cured by pressing (compressing). Then, the cosmetic material is removed from the mold (step S60).

[0071] Fig. 15 is a diagram for explaining the operation of curing and removing the cosmetic material filled using the cosmetic manufacturing apparatus 1 according to the present embodiment. Fig. 15 is a diagram showing a state in which the cosmetic material is cured and removed.

[0072] The mold 100 is formed of silicone rubber. By pressing the side of the silicone rubber mold 100, the mold 100 can be deformed. By deforming the mold 100, the cosmetic material can be removed from the mold 100 to create the cosmetic 200.

[0073] FIG. 16 and FIG. 17 are diagrams for explaining a cosmetic 200 manufactured by a cosmetic manufacturing method using the cosmetic manufacturing apparatus 1 according to the present embodiment. FIG. 16 is a top view of the cosmetic 200 as seen from above. FIG. 17 is a cross-sectional view of the cosmetic 200 cut along a cross-section corresponding to the same cross-section as FIG. 3. The cosmetic 200 has a plurality of convex portions 200a corresponding to the concave portions of the mold 100.

[0074] In FIGS. 16 and 17, the hatching indicated by YE, WT, RD, PK, and GN indicates cosmetic materials of yellow, white, red, pink, and green, respectively.

[0075] A cosmetic is manufactured using the cosmetic manufacturing apparatus 1 according to the present embodiment by a manufacturing method including step S10 and step S20.

[0076] The manufactured cosmetic 200 may be stored, for example, in a container. Further, the cosmetic 200 may be stored in a container, and a transparent cosmetic material may be poured into the container and fixed.

[0077] <Function and Effect> According to the cosmetic manufacturing method and the cosmetic manufacturing apparatus of the present disclosure, it is possible to provide a three-dimensional multi-color solid cosmetic formed with multi-color cosmetic materials on the surface. Further, since the mold 100 is used, the surface of the three-dimensional shape can be formed smoothly.

[0078] <Modification> [Modification 1] In the cosmetic manufacturing method and the cosmetic manufacturing apparatus of the present disclosure, the mold is not limited to the mold 100. For example, when using a molten and cooled solidified type cosmetic material raw material, the mold 110 fixed to the frame 111 shown in FIG. 18 may be used.

[0079] The mold 110 is formed of silicone rubber. The mold 110 is a thin film-like mold as compared with the mold 100. The mold 110 is fixed to the frame 111. The cosmetic material filled in the mold 110 by executing the above-described step S20 is cooled and solidified. Then, in the inverted state, the air inside the space 111S formed by the frame 111 and the mold 110 is exhausted from the valve 112, and the mold 110 is removed from the cosmetic material to remove the cosmetic 200.

[0080] [Modification Example 2] Also, in the cosmetic manufacturing method and the cosmetic manufacturing apparatus of the present disclosure, the cosmetic material is not limited to the melt-cooling and solidification type. For example, a wet molding type cosmetic material raw material (slurry) may be used as the cosmetic material.

[0081] FIG. 19 is a diagram for explaining the case where a wet molding type cosmetic material is used as the cosmetic material. When using a wet molding type cosmetic material raw material, for example, a mold 120 which is a microporous mold in which a large number of small holes are formed as shown in FIG. 19 may be used. The cosmetic material filled in the mold 120 by executing the above-described step S20 is cured by being pressurized by the press plate 121. Then, in the inverted state, air is introduced into the space 122S between the mold 120 and the lid 122 and pressurized with air pressure to remove the cosmetic material 300 from the mold 120. Then, it is dried by heating at a high temperature. And the cosmetic 310 is created.

[0082] Note that the microporous mold may be created from a metal plate with through holes formed by laminating and pressing plates with holes formed by photoetching. Also, a metal plate with through holes may be formed by a metal three-dimensional printer, and a microporous mold may be created from the formed metal plate.

[0083] Also, when using a wet molding type of cosmetic, a rubber mold such as silicone rubber may be used. FIG. 20 is a diagram for explaining the case of using a wet molding type of cosmetic as the cosmetic. FIG. 20 is an example of using a mold 130 which is a rubber mold. The cosmetic filled in the mold 130 by executing the above-described step S20 is cured by being pressurized by a press plate 131. Then, in the inverted state, the mold 130 is deformed and then the cosmetic 300 is removed. Then, it is dried by heating at a high temperature. Then, the cosmetic 310 is created.

[0084] Further, a molten cooling and solidifying type of cosmetic raw material can also be used for a mold 120 which is a microporous mold having a large number of small holes formed therein. In that case, the cosmetic filled in the mold 120 by executing the same step S20 is cooled and solidified in the mold and then inverted, and air is introduced into the space 122S between the mold 120 and the lid 122 and pressurized by air pressure to remove the cosmetic 300 from the mold 120.

[0085] [Modification Example of Cosmetic Discharge Port] The cosmetic discharge part of the cosmetic manufacturing apparatus 1 of the present disclosure is not limited to the cosmetic discharge part 11. For example, as the cosmetic discharge part, a dispenser that discharges the cosmetic using a piezo element may be used. Also, a dispenser that discharges the cosmetic using a uniaxial eccentric screw pump may be used.

[0086] [Modification Example of Horizontal Movement Device] In the present disclosure, the horizontal movement device 20 was movable in the X-axis direction and the Y-axis direction, but it may also be movable in the Z-axis direction. For example, it may be moved in the Z-axis direction according to the depth of the recess 100a.

[0087] Also, in the present disclosure, the horizontal movement device 20 moved a cosmetic discharge device including a plurality of cosmetic discharge parts 11 in the X-axis direction and the Y-axis direction, but one cosmetic discharge part 11 may be moved in the X-axis direction and the Y-axis direction, and the cosmetic discharge part 11 may be replaced when changing the color.

[0088] A cosmetic manufacturing apparatus 2 for replacing a cosmetic material discharging unit 11 will be described. FIG. 21 is a schematic configuration diagram of the cosmetic manufacturing apparatus 2 according to the present embodiment. The cosmetic manufacturing apparatus 2 uses a cosmetic material discharging device 10A instead of the cosmetic material discharging device 10 of the cosmetic manufacturing apparatus 1.

[0089] One cosmetic material discharging unit 11 can be attached to the cosmetic material discharging device 10A at a time. Further, the cosmetic material discharging device 10A is configured to be able to replace the cosmetic material discharging unit 11. And the cosmetic manufacturing apparatus 2 includes a standby unit 25 for waiting for the unused cosmetic material discharging unit 11.

[0090] When not in use, the plurality of cosmetic material discharging units 11 are placed on the standby unit 25. Then, the cosmetic manufacturing apparatus 2 moves the cosmetic material discharging unit 11 to be used from the standby unit 25 to the cosmetic material discharging device 10A and attaches it. And, similar to the cosmetic manufacturing apparatus 1, the cosmetic material discharging device 10A is moved by the horizontal movement device 20 to fill the mold 100 with the cosmetic material.

[0091] In FIG. 21, the cosmetic material discharging unit 11a is attached to the cosmetic material discharging device 10A, and the cosmetic material discharging units 11b, 11c, 11d, and 11e are waiting at the standby unit 25 which is a standby location.

[0092] When moving the cosmetic material discharging unit 11 to the cosmetic material discharging device 10A, for example, a robot arm or the like may be used. Also, the standby unit 25 may be placed on the placement surface 21A, and the horizontal movement device 20 may be moved to the standby unit 25 and attached.

[0093] Note that the plurality of cosmetic material discharging units 11 may be simultaneously moved using moving devices such as a plurality of robot arms and simultaneously filled into the mold 100. When using a plurality of moving devices, control is performed so that the plurality of cosmetic material discharging units 11 do not contact each other.

[0094] Further, a plurality of cosmetic manufacturing apparatuses 2 each having one cosmetic discharging unit 11 shown in FIG. 21 may be arranged in a filling line. The mold moves on the belt, and when it is arranged at a predetermined position of the base 21 of each cosmetic manufacturing apparatus 2, the cosmetic discharging apparatus 10A is moved to fill the mold 100 with a plurality of colors.

[0095] It should be considered that all the embodiments disclosed this time are illustrative in all respects and not restrictive. The above embodiments may be omitted, replaced, or changed in various forms without departing from the scope and gist of the appended claims.
