Description

Technical Field

[0001] The present invention relates to a stick-shaped cosmetic and a method for producing a stick-shaped cosmetic. Background Art

[0002] As a stick-shaped cosmetic material such as an eyebrow pencil and an eye shadow pencil, there are known products in which a cross section perpendicular to the axial direction has a multi-color region composed of a plurality of regions divided by colors. As such a technology, for example, Japanese Patent Publication No. 11-29439 describes a pen-shaped or automatic pen-shaped cosmetic material and a manufacturing method thereof, wherein the pen-shaped or automatic pen-shaped cosmetic material has a core body (stick-shaped cosmetic material) having a plurality of elongated and divided colored strips. Summary of the invention

[0003] In the stick-shaped cosmetics described above, the color pattern of the appearance can be given fineness and randomness, and the aesthetic sense can be improved. However, when used, a fixed color cannot be used, so there is room for improvement in usability.

[0004] Therefore, an object of one aspect of the present invention is to provide a stick-shaped cosmetic material having excellent aesthetics and usability.

[0005] One aspect of the present invention relates to a rod-shaped cosmetic material which is (1) a rod-shaped cosmetic material having a cross section perpendicular to an axial direction and having a multicolor region composed of a plurality of regions divided by N colors (N is an integer greater than 2), the cross section including a first cross section and a second cross section different from the first cross section, and the area ratio of the regions of each color in the multicolor region of the first cross section is equal to the area ratio of the regions of each color in the multicolor region of the second cross section.

[0006] In the above-mentioned rod-shaped cosmetic, by the color pattern of the multicolor area that its cross section has, can promote aesthetic feeling.In addition, the area ratio of the region of each color in the multicolor area of ​​the 1st cross section is equal to the area ratio of the region of each color in the multicolor area of ​​the 2nd cross section.Therefore, when the 1st cross section is a coating surface, the situation that the mixed mode of each color in the multicolor area is coated with and the 2nd cross section is a coating surface, the situation that the mixed mode of each color in the multicolor area is coated with, can present identical coating color (that is, fixedly painted), can obtain practical usability.Therefore, according to the present invention, can obtain the rod-shaped cosmetic of aesthetic feeling and usability excellence.

[0007] (2) In the above (1), the multicolor area may include a pattern consisting of at least any one of a dot pattern, a marble pattern, a camouflage pattern, and a mosaic pattern. In this case, the color pattern of the multicolor area can further enhance the aesthetics.

[0008] (3) In the above (1) or (2), the configuration of the regions of each color in the multicolor region of the first section may be different from the configuration of the regions of each color in the multicolor region of the second section. In this case, the multicolor region of the first section and the multicolor region of the second section may contain different patterns.

[0009] (4) In any of the above (1) to (3), the side surface of the stick-shaped cosmetic may include a stripe pattern extending in the axial direction and composed of a plurality of linear regions divided by colors. In this case, the stripe pattern on the side surface can further enhance the aesthetics.

[0010] (5) In any of the above (1) to (4), among the multiple regions divided by N colors in the multicolor region, the area of ​​the widest largest region may be less than 30% of the total area of ​​the multicolor region, and the area of ​​the narrowest smallest region may be more than 0.1% of the total area of ​​the multicolor region. In this case, a tiny color pattern can be included in the multicolor region.

[0011] (6) In any of the above (1) to (5), the number of times that the center line passing through the center of the multicolor area intersects the boundary lines of the plurality of areas divided by N colors may be 5 or more. In this case, a minute color pattern can be included in the multicolor area.

[0012] (7) In any of the above (1) to (6), the boundary lines of the multiple regions divided by N colors in the multicolor region may be irregular in shape. In this case, the multicolor region may include a color pattern consisting of multiple regions with irregular outlines.

[0013] (8) In any of the above (1) to (7), as the coating color, a designated color obtained by mixing N colors can be presented. In this case, when the stick-shaped cosmetic material is applied in a manner in which the colors of the multi-color area are mixed, the designated color can be presented as the coating color.

[0014] In the manufacture method of the rod-shaped cosmetic material described above, the mixed particles of each color are mixed in a mutually non-mixed mode to form an intermediate (multicolor sphere), and this intermediate is extruded by a forming machine to make the rod-shaped cosmetic material. Therefore, for example, near the extrusion opening (nozzle) of the forming machine, the intermediate sometimes rubs and is stretched with the inner wall surface of the forming machine in the extrusion direction. In this case, for example, multiple colors may mix and become dirty in the side of the rod-shaped cosmetic material that obtains, damaging the situation of the aesthetic feeling of the rod-shaped cosmetic material.

[0015] Therefore, another object of the present invention is to provide a method for producing a stick-shaped cosmetic material that can enhance beauty.

[0016] Another aspect of the present invention relates to a method for manufacturing a rod-shaped cosmetic, which is (9) a method for manufacturing a rod-shaped cosmetic having a cross section perpendicular to the axial direction and having a multi-color area composed of a plurality of areas divided by N colors (N is an integer greater than 2), the method comprising a first step and a second step, wherein the first step is to prepare a plurality of single-color core materials constituting the rod-shaped cosmetic for each of the N colors, and the second step is to extrude, after the above-mentioned first step, a plurality of core materials of N colors that are consistent in the axial direction or an intermediate containing a plurality of core materials of N colors along the axial direction by a molding machine, thereby obtaining a rod-shaped cosmetic.

[0017] In the manufacturing method of the stick-shaped cosmetic material, when the intermediate is extruded in the axial direction by the molding machine, even if the intermediate rubs against the inner wall surface of the molding machine in the axial direction, the core material contained therein is stretched in the axial direction, which can prevent the mixing of multiple different core materials, thereby preventing the mixing of multiple colors. Therefore, in the obtained stick-shaped cosmetic material, the side surface can be prevented from getting dirty, thereby improving the aesthetic feeling.

[0018] (10) In the above (9), in the second step, the plurality of core materials of N colors in the intermediate product may be randomly arranged. In this case, the color pattern of the multi-color region can be randomly configured.

[0019] (11) In the above (9) or (10), in the second step, the plurality of core materials of N colors in the intermediate can be arranged so as to form a pattern consisting of at least any one of a dot pattern, a marble pattern, a camouflage pattern, and a mosaic pattern when viewed from the axial direction. In this case, in the obtained stick-shaped cosmetic material, the color pattern contained in the multi-color region can further enhance the aesthetic feeling.

[0020] (12) In any of the above (9) to (11), the second step may include a step of bundling a plurality of core materials of N colors while mixing them in a uniform manner in the axial direction and inserting them into the interior of the cylinder member, and a step of axially compressing the plurality of core materials inserted into the cylinder member and integrating them to form a columnar intermediate. In this case, molding using a molding machine can be easily and reliably performed.

[0021] (13) In any one of the above (9) to (12), the cross-sectional shape of the core material may be a polygonal shape. In this case, a core material having a polygonal cross-sectional shape can be used.

[0022] (14) In any one of the above (9) to (13), the maximum width of the cross section of the core material may be 0.1 to 10 mm. In this case, a fine color pattern can be included in the multi-color region of the obtained stick-shaped cosmetic material.

[0023] (15) In any of the above (9) to (14), the oily component of the core material may be 30% by mass or more and 80% by mass or less. In this case, the intermediate is easily stretched when rubbed against the inner wall surface of the molding machine, so the above-mentioned effect of suppressing the mixing of multiple colors is particularly effective.

[0024] (16) In any of the above (9) to (15), the intermediate may contain 12 or more core materials. In this case, the multi-color region of the obtained stick-shaped cosmetic material can contain a variety of color patterns. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are marked with the same symbols, and repeated descriptions are appropriately omitted. For ease of understanding, a portion of the drawings is sometimes simplified or exaggerated, and the dimensions, proportions, etc. are not limited to those recorded in the drawings.

[0037] In the present invention, the stick-shaped cosmetic material is, for example, lipstick, lip gloss, lip liner, lip gloss, eyeliner, eyebrow gloss, eye shadow, concealer or beauty stick. The stick-shaped cosmetic material can be a stick-shaped object containing a material that is solid at room temperature (e.g., 25° C.), or can be a stick-shaped object containing a soft material (e.g., semi-solid, soft solid, jelly, mousse or a mixture containing the above forms, etc.) to replace the above materials or further containing the above soft material on the basis of the above materials.

[0038] like Figure 1 as well as Figure 2 As shown, the rod-shaped cosmetic material 1 is in the shape of a rod with a circular cross section. The rod-shaped cosmetic material 1 is contained in a cylindrical container 2 with a tapered front end, thereby constituting a cosmetic tool 100. The rod-shaped cosmetic material 1 is sent out from the front end side of the container 2 by a delivery mechanism not shown in the figure, and the cosmetic tool 100 can be used. That is, in the cosmetic tool 100, the rod-shaped cosmetic material 1 can be applied in a state where a part of its appearance is exposed. The rod-shaped cosmetic material 1 here is applied in a state where at least a part of the end face and the outer peripheral surface (side surface) of the axial direction (hereinafter, also referred to as "axial direction") of the rod-shaped cosmetic material 1 are exposed.

[0039] In the makeup tool 100, the rod-shaped cosmetic material 1 can be loaded on a wooden shaft or a resin shaft, or can be loaded on a refill. The rod-shaped cosmetic material 1 can be an oily rod-shaped cosmetic material, for example, the oily component can be more than 30% by mass and less than 80% by mass. The rod-shaped cosmetic material 1 can also include pearlescent pigments. The cross-sectional shape of the rod-shaped cosmetic material 1 is not particularly limited, and can be a polygonal shape, an elliptical shape, a flat circular shape, a drop shape (also referred to as a teardrop shape or a teardrop shape) and other shapes.

[0040] The outer peripheral surface of the rod-shaped cosmetic material 1 includes a stripe pattern. Here, the entire surface of the outer peripheral surface of the rod-shaped cosmetic material 1 is a stripe pattern. The stripe pattern of the outer peripheral surface of the rod-shaped cosmetic material 1 extends axially and is composed of a plurality of linear regions divided by N kinds (N is an integer greater than 2) of colors. The width of each stripe of the stripe pattern (the size of each of the plurality of linear regions on the circumferential direction) can be different from each other, or the width of a part of the stripes can be the same. The color matching mode (pattern) of the stripe pattern (the configuration of the color of each stripe) is randomly set.

[0041] like Figure 3 A. Figure 3 B and Figure 4 As shown, the cross section perpendicular to the axial direction of the stick-shaped cosmetic material 1 has a multicolor region 11, and the multicolor region 11 is composed of a plurality of regions divided by N colors. The multicolor region 11 here is a region that appears in the entire region of the cross section perpendicular to the axial direction in the stick-shaped cosmetic material 1. The multicolor region 11 is a region that appears in a cross section at any position in the axial direction of the stick-shaped cosmetic material 1. The multicolor region 11 includes a pattern composed of at least any pattern of a dot pattern, a marble pattern, a camouflage pattern, and a mosaic pattern.

[0042] A dot pattern is, for example, a pattern formed by regularly or irregularly arranging a plurality of dots (balls). A marble pattern is, for example, a pattern imitating marble, a pattern formed by closely overlapping swirls or stripes, or by overlapping flowing shapes in multiple colors. A camouflage pattern is, for example, a pattern that blends into the atmosphere of a forest, and is also called a protective color pattern. A mosaic pattern is, for example, a pattern formed by piecing together fragments.

[0043] The area of ​​the widest maximum area among the multiple areas divided by N colors in the multicolor area 11 is less than 30% of the total area of ​​the multicolor area 11. The area of ​​the narrowest minimum area among the multiple areas divided by N colors in the multicolor area 11 is more than 0.1% of the total area of ​​the multicolor area 11. The boundary lines of the multiple areas divided by N colors in the multicolor area 11 are irregular shapes. The boundary lines of the multiple areas divided by N colors in the multicolor area 11 are neither fixed straight lines nor fixed curves, but extend in a manner that includes undulations or chaos. The number of times that the center line passing through the center of the multicolor area 11 intersects with the boundary lines of the multiple areas divided by N colors is more than 5 times, preferably more than 10 times, more preferably more than 15 times, and even more preferably more than 20 times.

[0044] The area of ​​any region among the plurality of regions divided by N colors in the multi-color region 11 may be 0.1 to 30% of the entire multi-color region 11 , or 0.2 to 5%. There may be more than 30 regions of each color in the multi-color region 11. The multi-color region 11 here includes about 30 A color regions, about 30 B color regions, and about 30 C color regions.

[0045] The rod-shaped cosmetic material 1 can present the designated color obtained by mixing N kinds of colors of the multicolor region 11 as the coating color. That is, by mixing each color in the multicolor region 11 with the amount corresponding to the area ratio of each color in the multicolor region 11, the rod-shaped cosmetic material 1 can present the designated color as the coating color. As an example, in the rod-shaped cosmetic material 1, the area ratio of the A color region, the B color region, and the C color region of the multicolor region 11 is set to 1:1:1, and the designated color obtained by mixing the A color, the B color, and the C color in the ratio of 1:1:1 is used as the coating color. The designated color is theoretically the same as the color obtained by mixing the three colors of the A color, the B color, and the C color. For example, the A color is blue, the B color is orange, and the C color is green, and the designated color can be brown.

[0046] In this embodiment, the multicolor region 11a ( Figure 3 A), a multicolor region 11b of a second cross section at an arbitrary position different from the first cross section ( Figure 3 B), and a multicolor region 11c ( Figure 4 ) have the following relationship.

[0047] That is, the area ratio of the regions of each color in the multicolor region 11a of the first cross section is equal to the area ratio of the regions of each color in the multicolor region 11b of the second cross section. In other words, the ratio of the total area of ​​the A color region, the total area of ​​the B color region, and the total area of ​​the C color region in the multicolor region 11a is equal to the ratio of the total area of ​​the A color region, the total area of ​​the B color region, and the total area of ​​the C color region in the multicolor region 11b. In addition, the area ratio of the regions of each color in the multicolor region 11b of the second cross section is equal to the area ratio of the regions of each color in the multicolor region 11c of the third cross section. In other words, the ratio of the total area of ​​the A color region, the total area of ​​the B color region, and the total area of ​​the C color region in the multicolor region 11b is equal to the ratio of the total area of ​​the A color region, the total area of ​​the B color region, and the total area of ​​the C color region in the multicolor region 11c.

[0048] The configuration of the regions of each color in the multicolor region 11a of the first section is different from the configuration of the regions of each color in the multicolor region 11b of the second section. In other words, the shape of the pattern of the multicolor region 11a and / or the color matching mode of the pattern are different from the shape of the pattern of the multicolor region 11b and / or the color matching mode of the pattern. The configuration of the regions of each color in the multicolor region 11b of the second section is different from the configuration of the regions of each color in the multicolor region 11c of the third section. In other words, the shape of the pattern of the multicolor region 11b and / or the color matching mode of the pattern are different from the shape of the pattern of the multicolor region 11c and / or the color matching mode of the pattern.

[0049] Next, refer to Figure 5 The manufacturing method of the stick-shaped cosmetic 1 is described with reference to the flowchart of FIG.

[0050] First, prepare a plurality of monochromatic core materials constituting the rod-shaped cosmetic material 1 for each of N colors (step S1: the first process). The core material is a thin rod-shaped material, and the maximum width of the cross section of the core material is 0.1 to 10 mm. The shape of the cross section of the core material is not particularly limited, for example, it is circular. It should be noted that, as described later, the cross section of the core material can also be polygonal. The oily component of the core material is more than 30% by mass and less than 80% by mass. The core material may contain pearlescent pigments. Use more than 12 core materials, for example, use 20 for each of N colors, and use a total of 60. For example, the width of the core material is the width with the maximum value in the dimension passing through the center in a cross section orthogonal to its axial direction.

[0051] Next, prepare a cylindrical tube part with a bottom, gather the multiple core materials of N colors in a manner that their axial direction is along the axial direction of the tube part, and stuff them into the interior of the tube part (step S2). In the above-mentioned step S2, the multiple core materials of N colors are mixed and bundled into a bundle in a manner that is consistent in the axial direction, and they are stuffed into the interior of the tube part without gaps. Thus, the multiple core materials of N colors are arranged in the interior of the tube part without gaps and randomly. Here, the multiple core materials of N colors are arranged to form a pattern consisting of at least any pattern among a dot pattern, a marble pattern, a camouflage pattern, and a mosaic pattern when the bulk mass 51 obtained in the subsequent process is observed from the axial direction.

[0052] Next, a forging machine is used to compress and integrate the plurality of core materials inserted into the cylinder member in the axial direction. Figure 6 The cylindrical block (intermediate body) 51 shown (step S3). The block 51 includes a plurality of core materials of N colors. In the block 51, the plurality of core materials are integrated. The outer peripheral surface of the block 51 presents a stripe pattern consisting of a plurality of regions divided by N colors. The stripe pattern on the outer peripheral surface of the block 51 can be along the axial direction, and can be a straight line, a "く" shape, a sawtooth shape, or a curve.

[0053] The "く" shape is a shape in which a straight line is extended while bending once along the axial direction. Here, the "く" shape is a shape that extends linearly from one side in the axial direction toward the other side, then bends, and then extends linearly again. The serrated shape is a shape that extends in a serrated shape along the axial direction. In other words, the serrated shape is a shape in which a straight line is extended while bending multiple times along the axial direction. Here, the serrated shape is a shape formed by extending linearly from one side in the axial direction toward the other side, then bending, and repeating this action multiple times. Depending on the configuration of the multiple core materials at the inner outer edge of the tube component, the widths of the stripes of the striped pattern may be different from each other, or the widths of some stripes may be the same. The color matching pattern of the striped pattern is randomly set according to the configuration of the multiple core materials at the inner outer edge of the tube component.

[0054] Then, if Figure 7 as well as Figure 8As shown, the bulk body 51 is extruded by the extrusion molding machine 61, and a rod-shaped cosmetic material 1 is obtained (step S4). In the above step S4, the axial direction of the bulk body 51 is used as the molding direction D1, and the bulk body 51 is supplied into the cylinder 62 of the extrusion molding machine 61, and the bulk body 51 is extruded along the molding direction D1 by the piston 64. As a result, the bulk body 51 is stretched in the reduced diameter portion (near the nozzle 65) of the front end portion 62A of the cylinder 62, and at the same time, the outer peripheral portion thereof rubs against the inner wall surface, and the bulk body 51 moves and is squeezed, thereby being extruded from the nozzle 65 as a rod-shaped cosmetic material 1. Through the above operation, a rod-shaped cosmetic material 1 having a diameter (width) that is, for example, 1 / 10 of the diameter (width) of the bulk body 51 is obtained.

[0055] As described above, in the stick-shaped cosmetic material 1 involved in this embodiment, the color pattern of the multicolor region 11 in its cross section can enhance the aesthetic feeling. Figure 3 The area ratio of the regions of each color in section A) is the same as that of the multicolor region 11b in section 2 (see Figure 3 B) are equal in area ratio of each color region. Therefore, in the case where the first cross section is the coating surface and the multicolor region 11a is coated in a mixed manner, and in the case where the second cross section is the coating surface and the multicolor region 11b is coated in a mixed manner, the same coating color (i.e., fixed coloring) can be presented, and practical usability can be obtained. Therefore, a stick-shaped cosmetic material 1 with excellent aesthetics and usability can be obtained.

[0056] In the stick cosmetic 1, the multicolor region 11 includes a pattern consisting of at least one of a dot pattern, a marble pattern, a camouflage pattern, and a mosaic pattern. In this case, the color pattern of the multicolor region 11 can further enhance the aesthetic feeling.

[0057] In the stick-shaped cosmetic 1, the configuration of the regions of each color in the multicolor region 11a of the first cross section is different from the configuration of the regions of each color in the multicolor region 11b of the second cross section. In this case, the multicolor region 11a of the first cross section and the multicolor region 11b of the second cross section can include different patterns.

[0058] In the stick-shaped cosmetic material 1, the outer peripheral surface of the stick-shaped cosmetic material 1 includes a stripe pattern extending in the axial direction and consisting of a plurality of linear regions divided by colors. In this case, the stripe pattern on the outer peripheral surface can further enhance the aesthetic feeling. In the stick-shaped cosmetic material 1, the appearance of a multi-color pattern different from that on the outer peripheral surface can be obtained.

[0059] In the stick-shaped cosmetic material 1, among the multiple regions divided by N colors in the multicolor region 11, the area of ​​the widest largest region is less than 10% of the total area of ​​the multicolor region, and the area of ​​the narrowest smallest region is less than 1% of the total area of ​​the multicolor region. In this case, a minute color pattern can be included in the multicolor region 11.

[0060] In the stick-shaped cosmetic material 1, the center line passing through the center of the multicolor region 11 intersects the boundary lines of the plurality of regions divided by N colors at least 5 times. In this case, a minute color pattern can be included in the multicolor region 11.

[0061] In the stick-shaped cosmetic material 1, the boundary lines of the multiple regions divided by N colors in the multicolor region 11 are irregularly shaped. In this case, the multicolor region 11 can include a color pattern composed of multiple regions with irregular outlines.

[0062] The stick-shaped cosmetic material 1 can present a designated color obtained by mixing N colors as a coating color. In this case, when the stick-shaped cosmetic material 1 is applied in a manner that the colors of the multicolor region 11 are mixed, the designated color can be presented as the coating color.

[0063] Here, as mentioned above, when the bulk body 51 is extruded to the axial forming direction D1 by the extrusion molding machine 61, the outer peripheral surface of the bulk body 51 and the inner wall surface of the front end 62A of the extrusion molding machine 61 are axially rubbed. At this time, pressure will be applied near the nozzle 65 of the front end 62A of the extrusion molding machine 61, and the bulk body 51 is stretched. Even if the bulk body 51 is stretched like this, in the manufacturing method of the rod-shaped cosmetic material 1 involved in the present embodiment, the core material contained therein will also be stretched in the axial direction, and different multiple core materials can be suppressed from mixing, thereby multiple colors can be suppressed from mixing. Therefore, in the obtained rod-shaped cosmetic material 1, multiple colors can be suppressed from mixing and becoming dirty in its outer peripheral surface, thereby the aesthetic feeling can be improved. In the outer peripheral surface of the rod-shaped cosmetic material 1, the boundary of the color can be prevented from becoming unclear, and elongated bright colored strips can be formed.

[0064] In the method for manufacturing the stick-shaped cosmetic material 1, the plurality of core materials of N colors (the plurality of core materials inserted into the tube member) constituting the bulk body 51 may be randomly arranged. In this case, the color pattern of the multi-color region 11 can be randomly formed.

[0065] In the manufacturing method of the stick-shaped cosmetic material 1, the plurality of core materials of N colors constituting the bulk body 51 are arranged to form a pattern consisting of at least any one of a dot pattern, a marble pattern, a camouflage pattern, and a mosaic pattern when viewed from the axial direction. In this case, in the obtained stick-shaped cosmetic material 1, the color pattern included in the multicolor region 11 can enhance the aesthetic feeling.

[0066] The manufacturing method of the stick-shaped cosmetic material 1 includes a process of bundling a plurality of core materials of N colors in a uniform manner in the axial direction and inserting the bundle into a tube member; and a process of axially compressing the plurality of core materials inserted into the tube member and integrating them to form a large block 51. In this case, molding using an extrusion molding machine 61 can be easily and reliably performed.

[0067] In the method for producing the stick-shaped cosmetic material 1, the maximum width of the cross section of the core material is 0.1 to 10 mm. By using such a thin core material, the multi-color region 11 of the produced stick-shaped cosmetic material 1 can include a fine color pattern.

[0068] In the manufacturing method of the stick-shaped cosmetic material 1, the oily component of the core material is more than 30 mass % and less than 80 mass %. In this case, the large block 51 is easily stretched when rubbing against the inner wall surface of the extruder 61, thereby being able to suppress the above-mentioned effect of mixing multiple colors is particularly effective.

[0069] In the manufacturing method of the stick-shaped cosmetic material 1, the bulk body 51 may also include more than 12 core materials. In this case, the multicolor region 11 of the obtained stick-shaped cosmetic material 1 can include various color patterns. In the above, the above step S1 corresponds to the first process. The above steps S2 to S4 correspond to the second process.

[0070] As mentioned above, although the embodiment of the stick-shaped cosmetic material and the manufacturing method thereof which concerns on this invention is demonstrated, the stick-shaped cosmetic material and the manufacturing method thereof which concerns on this invention are not limited to the content of the said embodiment.

[0071] In the above-mentioned embodiment, for example, there are no particular limitations on the number of core materials used, the cross-sectional shape of the rod-shaped cosmetic 1, the shape of the pattern of the multicolor area 11, the color matching pattern of the pattern of the multicolor area 11, and the degree of detail of the pattern of the multicolor area 11.

[0072] As an example, 150 core materials may be used for each of N colors, so that a total of 450 core materials are used. In this case, Fig. 9 The stick-shaped cosmetic material 1A shown. The stick-shaped cosmetic material 1A has a circular cross-section. The area of ​​each region in the multicolor region 11 of the stick-shaped cosmetic material 1A can be 0.2 to 5% of the total area of ​​the multicolor region 11. The number of times that the center line passing through the center of the multicolor region 11 of the stick-shaped cosmetic material 1A intersects with the boundary lines of the plurality of regions can be more than 30 times.

[0073] As another example, 6 core materials may be used for each of N colors, so that a total of 18 core materials are used. In this case, Fig.10The stick-shaped cosmetic material 1C shown. The stick-shaped cosmetic material 1C has a circular cross-section.
