Summary of the Invention

Problems to be Solved by the Invention

[0004] In the rod-shaped cosmetic as described above, although fineness and randomness can be imparted to the color pattern of its appearance, and the aesthetic property can be enhanced, there is room for improvement in usability because a certain color usage cannot be achieved during use.

[0005] Therefore, an object of the present disclosure is to provide a rod-shaped cosmetic excellent in aesthetic property and usability.

Means for Solving the Problems

[0006] The rod-shaped cosmetic according to the present disclosure is a rod-shaped cosmetic having a multicolor region composed of a plurality of regions color-coded with N (N is an integer of 2 or more) colors in a cross-section perpendicular to the axial direction, the cross-section including a first cross-section and a second cross-section different from the first cross-section, and the area ratio of each color region in the multicolor region of the first cross-section being equal to the area ratio of each color region in the multicolor region of the second cross-section.

[0007] In this stick-shaped cosmetic, the aesthetic property can be enhanced by the color pattern of the multicolor region in its cross-section. Also, the area ratio of each color region in the multicolor region of the first cross-section is equal to the area ratio of each color region in the multicolor region of the second cross-section. Therefore, when applying so that the colors of the multicolor region are mixed when the first cross-section is the application surface, and when applying so that the colors of the multicolor region are mixed when the second cross-section is the application surface, it is possible to express the same applied color (that is, a certain color usage), and practical usability can be obtained. Therefore, according to the present disclosure, it is possible to obtain a stick-shaped cosmetic excellent in aesthetic property and usability.

[0008] (2) In the above (1), the multicolor region may include a pattern composed of at least any one of a dot pattern, a marble pattern, a camouflage pattern, and a mosaic pattern. In this case, the aesthetic property can be further enhanced by the color pattern of the multicolor region.

[0009] (3) In the above (1) or (2), the arrangement of each color region in the multicolor region of the first cross-section may be different from the arrangement of each color region in the multicolor region of the second cross-section. In this case, different patterns can be included in the multicolor region of the first cross-section and the multicolor region of the second cross-section.

[0010] (4) In any of the above (1) to (3), the side surface of the stick-shaped cosmetic may include a striped pattern composed of a plurality of linear regions extending along the axial direction and color-separated. In this case, the aesthetic property can be further enhanced by the striped pattern on the side surface.

[0011] (5) In any of the above (1) to (4), among the plurality of regions color-separated by N types of colors in the multicolor region, the area of the largest region, which is the widest, may be 30% or less of the total area of the multicolor region, and the area of the smallest region, which is the narrowest, may be 0.1% or more of the total area of the multicolor region. In this case, it is possible to include a fine color pattern in the multicolor region.

[0012] (6) In any of the above (1) to (5), the number of intersections between the center line passing through the center of the multicolor region and the boundary lines of the plurality of regions colored with N types of colors may be 5 or more. In this case, it becomes possible to include a fine color pattern in the multicolor region.

[0013] (7) In any of the above (1) to (6), the boundary lines of the plurality of regions colored with N types of colors in the multicolor region may be amorphous. In this case, it becomes possible to include a color pattern composed of a plurality of regions with an amorphous contour in the multicolor region.

[0014] (8) Any of the above (1) to (7) may be capable of expressing a predetermined color obtained by mixing N types of colors as an applied color. In this case, when the stick-shaped cosmetic is applied so that the colors of the multicolor region are mixed, the predetermined color can be expressed as the applied color.

Embodiments for Carrying Out the Invention

[0017] Hereinafter, embodiments according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and duplicate descriptions are omitted as appropriate. The drawings may be drawn with some parts simplified or exaggerated for ease of understanding, and dimensional ratios and the like are not limited to those described in the drawings.

[0018] In the present disclosure, the rod-shaped cosmetic is, for example, a lipstick, a lip stick, a lip liner, a lip gloss, an eyeliner, an eyebrow, an eyeshadow, a concealer, or a beauty stick. The rod-shaped cosmetic may be a rod-shaped object containing a solid material at normal temperature (for example, 25°C), or alternatively or additionally, a rod-shaped object containing a flexible material (for example, semi-solid, soft-solid, jelly-like, mousse-like, or a kneaded product containing these).

[0019] As shown in FIGS. 1 and 2, the rod-shaped cosmetic 1 has a rod shape with a circular cross-section. The rod-shaped cosmetic 1 is housed in a tapered cylindrical container 2 to constitute a cosmetic tool 100. The cosmetic tool 100 can feed out the rod-shaped cosmetic 1 from the tip side of the container 2 by a feeding mechanism (not shown) and be used. That is, in the cosmetic tool 100, the rod-shaped cosmetic 1 can be applied with a part of its appearance exposed. Here, the rod-shaped cosmetic 1 is applied with at least a part of the end face and the outer peripheral surface (side surface) in the axial direction (hereinafter, also simply referred to as the "axial direction") of the rod-shaped cosmetic 1 exposed.

[0020] In the cosmetic tool 100, the stick-shaped cosmetic 1 may be loaded on a wooden shaft or a resin shaft, or may be loaded in a feeding cartridge. The stick-shaped cosmetic 1 may be an oil-based stick-shaped cosmetic, for example, the oil-based component may be 30% by mass or more and 80% by mass or less. The stick-shaped cosmetic 1 may contain a pearl pigment. The cross-sectional shape of the stick-shaped cosmetic 1 is not particularly limited, and may be a shape such as a polygonal shape, an elliptical shape, a flat circular shape, a droplet shape (also referred to as a teardrop shape or a teardrop shape).

[0021] The outer peripheral surface of the stick-shaped cosmetic 1 includes a striped pattern. Here, the entire outer peripheral surface of the stick-shaped cosmetic 1 exhibits a striped pattern. The striped pattern on the outer peripheral surface of the stick-shaped cosmetic 1 extends along the axial direction and is composed of a plurality of linear regions colored with N types (N is an integer of 2 or more) of colors. The width of each stripe of the striped pattern (the dimension in the circumferential direction of each of the plurality of linear regions) may be different from each other, or the widths of some stripes may be the same. The color arrangement pattern (the arrangement of the colors of each stripe) of the striped pattern is set randomly.

[0022] As shown in FIGS. 3(a), 3(b) and 4, the stick-shaped cosmetic 1 has a multicolor region 11 in which a cross-section perpendicular to the axial direction is composed of a plurality of regions colored with N types of colors. The multicolor region 11 here is a region that appears in the entire cross-section perpendicular to the axial direction in the stick-shaped cosmetic 1. The multicolor region 11 is a region that appears in the cross-section at any position in the axial direction of the stick-shaped cosmetic 1. The multicolor region 11 includes a pattern composed of at least one of a dot pattern, a marble pattern, a camouflage pattern and a mosaic pattern.

[0023] The dot pattern is, for example, a pattern formed by arranging a plurality of dots (balls) regularly or irregularly. The marble pattern is, for example, a pattern imitating marble, and is a pattern formed by overlapping fine swirls or streaks or overlapping a flowing shape multiple times with a plurality of colors. The camouflage pattern is, for example, a pattern having an atmosphere of blending into a forest or the like, and is also referred to as a camouflage pattern. The mosaic pattern is, for example, a pattern formed by joining small pieces together.

[0024] Among the plurality of regions color-coded with N types of colors in the multicolor region 11, the area of the largest region, which is the largest, is 30% or less of the total area of the multicolor region 11. Among the plurality of regions color-coded with N types of colors in the multicolor region 11, the area of the smallest region, which is the smallest, is 0.1% or more of the total area of the multicolor region 11. The boundary lines of the plurality of regions color-coded with N types of colors in the multicolor region 11 are amorphous. The boundary lines of the plurality of regions color-coded with N types of colors in the multicolor region 11 are not a fixed straight line, not a fixed curve, and extend including fluctuations or irregularities. The number of intersections between the center line passing through the center of the multicolor region 11 and the boundary lines of the plurality of regions color-coded with N types of colors is 5 or more, preferably 10 or more, more preferably 15 or more, and even more preferably 20 or more.

[0025] The area of any one of the plurality of regions color-coded with N types of colors in the multicolor region 11 may be 0.1 to 30% of the whole of the multicolor region 11, or may be 0.2 to 5%. Each color region in the multicolor region 11 may be 30 or more in number. Here, the multicolor region 11 includes approximately 30 A-color regions, approximately 30 B-color regions, and approximately 30 C-color regions.

[0026] The stick-shaped cosmetic 1 can express a predetermined color obtained by mixing N types of colors in the multicolor region 11 as an applied color. That is, the stick-shaped cosmetic 1 can express a predetermined color as an applied color by mixing each color in the multicolor region 11 in an amount corresponding to the area ratio of the regions of each color in the multicolor region 11. As an example, in the stick-shaped cosmetic 1, the area ratio of the A-color region, B-color region, and C-color region in the multicolor region 11 is set to 1:1:1, and the predetermined color obtained by mixing A color, B color, and C color at 1:1:1 is used as the applied color. The predetermined color is theoretically the same color as the mixture of the three colors A, B, and C. For example, A color may be blue, B color may be orange, C color may be green, and the predetermined color may be brown.

[0027] In this embodiment, the multi-color region 11a (Fig. 3(a)) of the first cross-section at an arbitrary position of the rod-shaped cosmetic 1, the multi-color region 11b (Fig. 3(b)) of the second cross-section at an arbitrary position different from the first cross-section, and the multi-color region 11c (Fig. 4) of the third cross-section at an arbitrary position different from the first and second cross-sections have the following relationship.

[0028] That is, the area ratio of each color region in the multi-color region 11a of the first cross-section is equal to the area ratio of each color region in the multi-color 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 multi-color 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 multi-color region 11b. Also, the area ratio of each color region in the multi-color region 11b of the second cross-section is equal to the area ratio of each color region in the multi-color 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 multi-color 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 multi-color region 11c.

[0029] The arrangement of each color region in the multi-color region 11a of the first cross-section is different from the arrangement of each color region in the multi-color region 11b of the second cross-section. In other words, the shape of the pattern and / or the color scheme pattern of the multi-color region 11a is different from the shape of the pattern and / or the color scheme pattern of the multi-color region 11b. The arrangement of each color region in the multi-color region 11b of the second cross-section is different from the arrangement of each color region in the multi-color region 11c of the third cross-section. In other words, the shape of the pattern and / or the color scheme pattern of the multi-color region 11b is different from the shape of the pattern and / or the color scheme pattern of the multi-color region 11c.

[0030] Next, a method for manufacturing the rod-shaped cosmetic 1 will be described with reference to the flowchart of Fig. 5.

[0031] First, a plurality of single-color core materials constituting the rod-shaped cosmetic 1 are prepared for each of N types of colors (step S1: first step). 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, but for example, it is circular. Note that the cross-section of the core material may be polygonal as described later. The oil-based component of the core material is 30% by mass or more and 80% by mass or less. The core material may contain a pearl pigment. 12 or more core materials are used. For example, 20 core materials are used for each of N types of colors, for a total of 60 core materials. For example, the width of the core material is the largest value among the dimensions passing through the center in the cross-section orthogonal to its axial direction.

[0032] Subsequently, a bottomed cylindrical tubular member is prepared, and a plurality of core materials of N types of colors are aligned with their axial directions along the axial direction of the tubular member and packed into the tubular member (step S2). In step S2 above, a plurality of core materials of N types of colors are bundled while aligning their axial directions and mixing them, and are packed into the tubular member without gaps. Thereby, a plurality of core materials of N types of colors are randomly arranged in the tubular member without gaps. Here, a plurality of core materials of N types of colors are arranged so that the bulk mass 51 obtained in a subsequent step forms a pattern composed 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.

[0033] Subsequently, the plurality of core materials packed inside the tubular member are compressed and integrated in the axial direction using a press machine. Thereby, a columnar bulk mass (intermediate body) 51 shown in FIG. 6 is formed (step S3). The bulk mass 51 includes a plurality of core materials of N types of colors. In the bulk mass 51, a plurality of core materials are integrated. The outer peripheral surface of the bulk mass 51 exhibits a striped pattern composed of a plurality of regions color-coded with N types of colors. The striped pattern on the outer peripheral surface of the bulk mass 51 only needs to be along the axial direction, and may be linear, zigzag, zigzag-shaped, or curved.

[0034] The U-shaped form is a shape in which a straight line extends while bending once along the axial direction. Here, the U-shaped form is a shape in which, from one side to the other side in the axial direction, after extending linearly, it bends and then extends linearly. The zigzag shape is a shape that extends in a zigzag shape along the axial direction. In other words, the zigzag shape is a shape in which a straight line extends while bending multiple times along the axial direction. Here, the zigzag shape is a shape in which, from one side to the other side in the axial direction, after extending linearly, it bends, and this is repeated multiple times. The width of each stripe of the stripe pattern may be different from each other according to the arrangement of a plurality of core materials at the outer edge part inside the cylindrical member, or the widths of some stripes may be the same. The color matching pattern of the stripe pattern is set randomly according to the arrangement of a plurality of core materials at the outer edge part inside the cylindrical member.

[0035] Subsequently, as shown in FIGS. 7 and 8, the bulk mass 51 is extrusion molded by an extrusion molding machine 61 to obtain the rod-shaped cosmetic 1 (step S4). In step S4 above, with its axial direction as the molding direction D1, the bulk mass 51 is supplied into the cylinder 62 of the extrusion molding machine 61, and the bulk mass 51 is pushed out along the molding direction D1 by the piston 64. As a result, the bulk mass 51 is stretched at the reduced-diameter part (near the nozzle 65) of the tip part 62A of the cylinder 62, and at the same time, its outer peripheral part moves while rubbing against the inner wall surface, is constricted, and is extruded from the nozzle 65 as the rod-shaped cosmetic 1. As described above, for example, a rod-shaped cosmetic 1 having a diameter (width) that is 1 / 10 of the diameter (width) of the bulk mass 51 can be obtained.

[0036] As described above, in the stick-shaped cosmetic 1 according to the present embodiment, the aesthetic property can be enhanced by the color pattern of the multicolor region 11 in the cross section thereof. Further, the area ratio of each color region in the multicolor region 11a (see Fig. 3(a)) of the first cross section is equal to the area ratio of each color region in the multicolor region 11b (see Fig. 3(b)) of the second cross section. Therefore, when applying the stick-shaped cosmetic 1 such that the colors of the multicolor region 11a are mixed when the first cross section is the application surface, and when applying it such that the colors of the multicolor region 11b are mixed when the second cross section is the application surface, it is possible to express the same applied color (that is, consistent color usage), and practical usability can be obtained. Therefore, it is possible to obtain the stick-shaped cosmetic 1 with excellent aesthetic property and usability.

[0037] In the stick-shaped cosmetic 1, the multicolor region 11 includes a pattern composed of at least any one of a dot pattern, a marble pattern, a camouflage pattern, and a mosaic pattern. In this case, the aesthetic property can be further enhanced by the color pattern of the multicolor region 11.

[0038] In the stick-shaped cosmetic 1, the arrangement of each color region in the multicolor region 11a of the first cross section is different from the arrangement of each color region in the multicolor region 11b of the second cross section. In this case, different patterns can be included in the multicolor region 11a of the first cross section and the multicolor region 11b of the second cross section.

[0039] In the stick-shaped cosmetic 1, the outer peripheral surface of the stick-shaped cosmetic 1 includes a stripe pattern composed of a plurality of linear regions extending along the axial direction and color-separated. In this case, the aesthetic property can be further enhanced by the stripe pattern on the outer peripheral surface. In the stick-shaped cosmetic 1, it is possible to obtain an appearance with different multicolor patterns on the cross section and the outer peripheral surface.

[0040] In the stick-shaped cosmetic 1, among the plurality of regions color-separated by N types of colors in the multicolor region 11, the area of the largest region, which is the widest, is 10% or less of the total area of the multicolor region, and the area of the smallest region, which is the narrowest, is 1% or less of the total area of the multicolor region. In this case, it is possible to include a fine color pattern in the multicolor region 11.

[0041] In the rod-shaped cosmetic 1, the number of intersections between the center line passing through the center of the multicolor region 11 and the boundary lines of the plurality of regions color-coded with N types of colors is 5 or more. In this case, it becomes possible to include a fine color pattern in the multicolor region 11.

[0042] In the rod-shaped cosmetic 1, the boundary lines of the plurality of regions color-coded with N types of colors in the multicolor region 11 are amorphous. In this case, it becomes possible to include in the multicolor region 11 a color pattern composed of a plurality of regions with amorphous outlines.

[0043] The rod-shaped cosmetic 1 can express a predetermined color obtained by mixing N types of colors as a coating color. In this case, when the rod-shaped cosmetic 1 is applied so that the colors in the multicolor region 11 are mixed, the predetermined color can be expressed as the coating color.

[0044] Here, as described above, when the bulk mass 51 is extruded in the molding direction D1, which is the axial direction, by the extrusion molding machine 61, the outer peripheral surface of the bulk mass 51 rubs against the inner wall surface of the tip portion 62A of the extrusion molding machine 61 along the axial direction. At this time, pressure is applied near the nozzle 65 of the tip portion 62A of the extrusion molding machine 61, and the bulk mass 51 is stretched. Even when the bulk mass 51 is stretched in this way, in the manufacturing method of the rod-shaped cosmetic 1 according to the present embodiment, the core material contained therein is stretched in the axial direction, and it is possible to suppress the mixing of different core materials, so it is possible to suppress the mixing of a plurality of types of colors. Therefore, in the manufactured rod-shaped cosmetic 1, it is possible to suppress the mixing of a plurality of types of colors on its outer peripheral surface and prevent it from becoming dirty, thereby enhancing the aesthetic property. On the outer peripheral surface of the rod-shaped cosmetic 1, it is possible to prevent the color boundary from becoming unclear and form long and vivid color streaks.

[0045] In the manufacturing method of the rod-shaped cosmetic 1, the plurality of core materials of N types of colors constituting the bulk mass 51 (the plurality of core materials packed in the cylindrical member) may be randomly arranged. In this case, it becomes possible to randomly configure the color pattern of the multicolor region 11.

[0046] In the method for manufacturing the rod-shaped cosmetic 1, the plurality of core materials of N colors that make up the bulk mass 51 are arranged so as to form a pattern composed of at least 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 manufactured rod-shaped cosmetic 1, the aesthetic property can be enhanced by the color pattern included in the multicolor region 11.

[0047] In the method for manufacturing the rod-shaped cosmetic 1, it includes a step of bundling a plurality of core materials of N colors while aligning their axial directions and packing them into the inside of a cylindrical member, and a step of compressing and integrating the plurality of core materials packed in the cylindrical member in the axial direction to form the bulk mass 51. In this case, it becomes possible to easily and surely perform molding by the extrusion molding machine 61.

[0048] In the method for manufacturing the rod-shaped cosmetic 1, the maximum width of the cross-section of the core material is 0.1 to 10 mm. By using such thin core materials, it becomes possible to include a fine color pattern in the multicolor region 11 of the manufactured rod-shaped cosmetic 1.

[0049] In the method for manufacturing the rod-shaped cosmetic 1, the oil-based component of the core material is 30 mass% or more and 80 mass% or less. In this case, since the bulk mass 51 is easily stretched when rubbed against the inner wall surface of the extrusion molding machine 61, the effect of suppressing the mixing of multiple types of colors is particularly effective.

[0050] In the method for manufacturing the rod-shaped cosmetic 1, the bulk mass 51 may contain 12 or more core materials. In this case, it becomes possible to include various color patterns in the multicolor region 11 of the manufactured rod-shaped cosmetic 1. In the above, the above step S1 corresponds to the first step. The above steps S2 to S4 correspond to the second step.

[0051] As described above, the embodiments of the rod-shaped cosmetic and its manufacturing method according to the present disclosure have been described, but the rod-shaped cosmetic and its manufacturing method according to the present disclosure are not limited to the contents of the above-described embodiments.

[0052] In the above-described embodiments, for example, the number of core materials used, the cross-sectional shape of the rod-shaped cosmetic 1, the shape of the pattern in the multicolor region 11, the color combination pattern of the pattern in the multicolor region 11, and the density of the pattern in the multicolor region 11 are not particularly limited.

[0053] As an example, 150 core materials may be used for each of the N types of colors, for a total of 450 core materials. In this case, the rod-shaped cosmetic 1A shown in FIG. 9 can be obtained. The rod-shaped cosmetic 1A has a circular cross-section. The area of each region in the multicolor region 11 of the rod-shaped cosmetic 1A may be 0.2 to 5% of the total area of the multicolor region 11. The number of times the center line passing through the center of the multicolor region 11 of the rod-shaped cosmetic 1A intersects the boundary lines of the plurality of regions may be 30 or more.

[0054] As another example, 6 core materials may be used for each of the N types of colors, for a total of 18 core materials. In this case, the rod-shaped cosmetic 1C shown in FIG. 10 can be obtained. The rod-shaped cosmetic 1C has a circular cross-section. The area of each region in the multicolor region 11 of the rod-shaped cosmetic 1C may be 5.3 to 23.2% of the total area of the multicolor region 11. The number of times the center line passing through the center of the multicolor region 11 of the rod-shaped cosmetic 1C intersects the boundary lines of the plurality of regions may be 5 or more.

[0055] The rod-shaped cosmetic of the above-described embodiments may have a region of a predetermined color, which is an applied color obtained by mixing N types of colors, on the outer peripheral surface (side surface). For example, in the rod-shaped cosmetic 1E shown in FIG. 11, a region of a predetermined color is provided at the outer edge of the cross-section, and the entire outer peripheral surface of the rod-shaped cosmetic 1E may be a region of a predetermined color. In such a rod-shaped cosmetic 1E, the predetermined color as the applied color can be exhibited in its appearance. Therefore, the user can easily grasp the applied color.

[0056] In the above-described embodiments, a core material having a polygonal cross-sectional shape may be used. In this case, a core material having a polygonal cross-sectional shape can be utilized. Note that the cross-sectional shape of the core material is not particularly limited and may be an elliptical shape.

[0057] In the above-described embodiments, the bulk block 51 was formed as an intermediate body. However, it is also possible to use a bundle of a plurality of core materials of N types of colors aligned in the axial direction without forming the bulk block 51 (without performing the above steps S2 and S3). In this case, a guide of an arbitrary shape may be inserted into the cylinder 62 of the extrusion molding machine 61, and a plurality of such core materials may be arranged therein. In the above-described embodiments, powder or paste may be attached to the core material, or powder or paste may be attached to a bundle of a plurality of core materials. In the above-described embodiments, the oil absorption amount or hardness of the core material is not limited, and various oil absorption amounts or hardnesses may be used.

[0058] In the above-described embodiments, the value of 0.1 mm, which is the maximum width of the cross-section of the core material, may be approximately 0.1 mm and may have errors in measurement or the like. In the above-described embodiments, the value of 10 mm, which is the maximum width of the cross-section of the core material, may be approximately 10 mm and may have errors in measurement or the like. In the above-described embodiments, 30% by mass, which is the oily component of the core material, may be approximately 30% by mass and may have errors in measurement or the like. In the above-described embodiments, 80% by mass, which is the oily component of the core material, may be approximately 80% by mass and may have errors in measurement or the like.

[0059] In the above-described embodiments, the term "equal" may not only be completely equal but also approximately equal, allowing for differences in the degree of measurement errors. In the above-described embodiments, 10% of the total area of the multicolor region 11 may be approximately 10% and may have errors in measurement or the like. In the above-described embodiments, 1% of the total area of the multicolor region 11 may be approximately 1% and may have errors in measurement or the like.
