Mode for Carrying Out the Invention

[0016] The present invention is a method for manufacturing a multicolor solid cosmetic having irregular patterns on its surface. Hereinafter, embodiments thereof will be described with reference to the drawings. The method for manufacturing a multicolor solid cosmetic according to the present invention is particularly suitable for manufacturing blush, eyeshadow, and other face powders, that is, multicolor solid powder cosmetics for makeup.

[0017] (Example 1) FIG. 1 is a flowchart showing the method for manufacturing a multicolor solid cosmetic according to the first embodiment of the present invention, FIG. 2 is a perspective view showing a powder cosmetic molded body according to the first embodiment of the present invention, and FIG. 3 is a perspective view showing a multicolor cosmetic molded body according to the first embodiment of the present invention.

[0018] As shown in Figure 1, the method for manufacturing the multicolor solid cosmetic of this embodiment comprises a powder cosmetic molded body preparation step S1, a multicolor cosmetic molded body preparation step S2, a cutting step S3, a filling step S4, and a compression step S5. By sequentially executing these steps, it is possible to create a multicolor solid cosmetic having a cracked, edgy, irregular pattern on the cosmetic surface, similar to the cross-section of marble.

[0019] The powder cosmetic molding process S1 is a process of molding a single-color powder cosmetic to create a powder cosmetic molding 10.

[0020] Specifically, a single-color slurry or clay-like powder cosmetic bulk is molded into a rod shape using methods such as injection molding with a screw extrusion hopper or press molding with a press die, thereby creating the powder cosmetic molded body 10 shown in Figure 2. By forming the powder cosmetic molded body into a rod shape such as a cylinder or prism, the shredding process described later can be carried out easily and efficiently.

[0021] The color of the powder cosmetic molded product 10 can be arbitrarily selected according to the type of cosmetic product.

[0022] The powder cosmetic used in the preparation of the powder cosmetic molded body 10 can be any powder that can be molded into a rod shape, and the form during molding is not particularly limited. For example, powder cosmetic in the form of powder, granules, aggregates, clay, slurry, or mixtures thereof can be used in the preparation of the powder cosmetic molded body 10. When the powder cosmetic is in these forms, it is possible to adjust it by adding an appropriate amount of a known volatile solvent as needed.

[0023] The specific components and raw materials of the powdered cosmetic composition in this invention can be those that have been widely used in the past, and one example is those published in Japanese Patent Publication No. 2909923.

[0024] As shown in Figure 3, the multi-color cosmetic molded body creation step S2 is a step in which a powder cosmetic 11 of a different color (second color) from the color (first color) of the powder cosmetic molded body 10 created in the powder cosmetic molded body creation step S1 is applied to the powder cosmetic molded body 10 to create a multi-color cosmetic molded body 20.

[0025] Specifically, a multi-color cosmetic molded body 20, which is shaped like a rod overall, is created by attaching the powder cosmetic 11 to the circumferential surface of the powder cosmetic molded body 10.

[0026] The method for attaching the powder cosmetic 11 to the surface of the powder cosmetic molded body 10 is not particularly limited. For example, one method is to roll the powder cosmetic molded body 10 on top of the powder cosmetic 11 placed in a flat tray to attach the powder cosmetic 11 to the surface of the powder cosmetic molded body 10, or to place the powder cosmetic molded body 10 on top of the powder cosmetic 11 scattered on a belt conveyor, and then drive the belt conveyor while pressing down on the powder cosmetic molded body 10 with a pressing member to attach the powder cosmetic 11 to the surface of the powder cosmetic molded body 10. By using these methods, a multi-color cosmetic molded body 20 having a substantially uniform layer of powder cosmetic 11 around the surface of the powder cosmetic molded body 10 can be created.

[0027] The area of ​​the powder cosmetic molded body 10 to which the powder cosmetic 11 is attached is arbitrary. As shown in Figure 3, it may be attached only to the sides of the powder cosmetic molded body 10, or it may be attached to the entire surface including both ends (bottom) in the longitudinal direction of the powder cosmetic molded body 10. There are no particular limitations.

[0028] The thickness of the layer of powder cosmetic 11 formed around the powder cosmetic molded body 10 can be appropriately adjusted according to the desired width of the pattern to appear on the multicolor solid cosmetic 50.

[0029] Furthermore, in order to obtain a multi-colored solid cosmetic 50 with a more complex pattern, two or more layers of powder cosmetic 11 may be formed on the powder cosmetic molded body 10. In that case, it is preferable to use a powder cosmetic of a different color from the color of the first layer of powder cosmetic 11 for the second and subsequent layers.

[0030] The cutting step S3 is a step in which the multicolor cosmetic molded body 20 created in the multicolor cosmetic molded body creation step S2 is cut into multiple fragments. Figure 4 is a perspective view showing the cutting method of the cutting step S3 according to the first embodiment of the present invention, where (a) is a diagram showing a vertical slice cut and (b) is a diagram showing an inclined slice cut.

[0031] In the cutting process S3, it is sufficient to create multiple fragments from the multicolor cosmetic molded body 20, and the cutting method is arbitrary. For example, slicing or mincing can be applied.

[0032] In this embodiment, as shown in Figure 4(a), a vertical slicing method was applied. That is, by lowering the cutter 30 perpendicularly to the central axis M of the multicolor cosmetic molded body 20, the multicolor cosmetic molded body 20 was sliced ​​into rings to create multiple fragments 20a. In this case, a characteristic of the fragments 20a is that the circular cross-section of the powder cosmetic molded body 10 is surrounded by a layer of powder cosmetic 11.

[0033] In addition to slicing perpendicular to the central axis M, as shown in Figure 4(b), inclined slicing can also be applied. That is, by sliding the cutter 30 downward at an angle θ with respect to the central axis M of the multicolor cosmetic molded body 20, multiple fragments 20b can be created. In this case, the characteristic of the fragments 20b is that the elliptical cross-section of the powder cosmetic molded body 10 is surrounded by a layer of powder cosmetic 11. In other words, it is possible to create fragments 20b with a larger cross-section of the powder cosmetic molded body 10 than fragments 20a.

[0034] The filling step S4 is the step of filling the cosmetic tray 40 with fragments 20a of the multicolor cosmetic molded body 20. Figure 5 is a perspective view showing the filling step according to the first embodiment of the present invention.

[0035] As shown in Figure 5, in the filling step S4, multiple fragments 20a made from the multicolor cosmetic molded body 20 are filled into the cosmetic tray 40 by being randomly stacked. After the filling step S4 is performed, the compression step S5 is executed.

[0036] Compression step S5 is a step in which the multiple fragments 20a filled in the cosmetic tray 40 are compressed. Figure 6 is a perspective view showing the multicolored solid cosmetic 50 obtained after the compression step.

[0037] Specifically, the multiple fragments 20a filled in the cosmetic tray 40 are pressed toward the bottom of the cosmetic tray 40 using a known press device (not shown). This produces a multi-colored solid cosmetic 50 having a smooth surface, as shown in Figure 6.

[0038] As shown in Figure 6, the multicolor solid cosmetic 50 obtained through the above process exhibits a pattern on its surface in which lines or surfaces having the color of the powder cosmetic 11 attached to the circumferential surface of the powder cosmetic molded body 10 are irregularly and crack-like within the colored surfaces of the powder cosmetic molded body 10, resembling the cross-sectional pattern of marble. In other words, according to the present invention, it is possible to manufacture a multicolor solid cosmetic having a cracked, sharp, and irregular pattern resembling the cross-section of marble, which has been difficult to express conventionally.

[0039] In particular, in the compression step S5 of this embodiment, since sliced ​​fragments 20a and 20b are used, many long and slightly thick crack-like patterns (patterns formed by layers of powder cosmetic 11 attached to the circumferential surface of the powder cosmetic molded body 10) are formed.

[0040] Figure 7 shows photographs of actual multicolor solid cosmetics obtained by compressing slices of a multicolor cosmetic molded body, where (a) is a photograph of sample 1 and (b) is a photograph of sample 2. By changing the cutting method and direction when slicing the multicolor cosmetic molded body 20, a variety of multicolor solid cosmetics 50 can be produced, as shown in Figures 7(a) and (b), all of which have long and slightly thick crack-like patterns, but with different patterns appearing in different ways.

[0041] Furthermore, since the multicolored solid cosmetic 50 is manufactured by compressing multiple multicolored fragments 20a that are randomly stacked in the cosmetic dish 40, an irregular pattern can be formed in the thickness direction of the multicolored solid cosmetic 50. As a result, when the multicolored solid cosmetic 50 is used by scraping it from the top surface, the pattern changes little by little.

[0042] (Example 2) Next, a second embodiment of the present invention will be described.

[0043] Figure 8 is a perspective view showing the cutting process applied to the second embodiment of the present invention, Figure 9 is a perspective view showing the filling process according to the second embodiment of the present invention, and Figure 10 is a perspective view showing the multicolor solid cosmetic obtained through the compression process.

[0044] In the method for producing multicolor solid cosmetic composition of this embodiment, the cutting method in cutting step S3 differs from that of the manufacturing method of the first embodiment described above.

[0045] As shown in Figure 8, in this embodiment, the method used for cutting the multicolor solid molded body 20 was to finely chop it. Specifically, the cutter 30 was lowered from random directions relative to the central axis M of the multicolor cosmetic molded body 20 to finely chop the multicolor cosmetic molded body 20, creating multiple small fragments 20c. The characteristics of the fragments 20c in this case are that the fragments 20c themselves are small, and that in addition to multicolor fragments 20c having two colors from the powder cosmetic molded body 10 and the powder cosmetic 11, there are also single-color fragments 20c having only the color of the powder cosmetic molded body 10, and single-color fragments 20c having only the color of the powder cosmetic 11.

[0046] As shown in Figure 9, after the multiple fragments 20c are filled into the cosmetic tray 40 in the filling step S4, and then the compression step S5 is performed, a multicolor solid cosmetic 51 having a different surface pattern from the multicolor solid cosmetic 50 of the first embodiment is produced, as shown in Figure 10.

[0047] In the compression step S5, all the fragments 20c are small, and the multicolored fragments 20c made of the powder cosmetic molded body 10 and the powder cosmetic 11, the monocolored fragments 20c having only the color of the powder cosmetic molded body 10, and the monocolored fragments 20c having only the color of the powder cosmetic 11 are mixed together and compressed to form the multicolored solid cosmetic 51. As a result, the surface pattern of the multicolored solid cosmetic 51 has more short and fine crack-like patterns (patterns formed by layers of powder cosmetic 11 attached to the circumferential surface of the powder cosmetic molded body 10) than the surface pattern of the multicolored solid cosmetic 50 according to Example 1. This pattern is also a type of cross-sectional pattern of marble.

[0048] Figure 11 shows photographs of actual multicolor solid cosmetics obtained by compressing fragments obtained by finely chopping a multicolor cosmetic molded body. (a) is a photograph showing sample 1, and (b) is a photograph showing sample 2. When finely chopping the multicolor cosmetic molded body 20, by cutting the fragments 20c to a medium or fine size, a variety of multicolor solid cosmetics 51 with different patterns of crack-like formation can be obtained, as shown in Figures 11(a) and (b).

[0049] Furthermore, the size of the fragments 20c obtained by finely chopping the multicolor cosmetic molded body 20 is not particularly limited, and it is possible to use fragments 20c that are finely chopped overall, fragments 20c that are coarsely chopped, or fragments 20c that are a mixture of both.

[0050] Other components, functions, and effects are the same as those of the first embodiment described above, so their description is omitted.

[0051] (modified version) Here, we will describe modified examples of multi-color cosmetic molded articles with reference to Figure 12. Figure 12 is a perspective view showing modified examples of multi-color cosmetic molded articles, where (a) shows the first modified example and (b) shows the second modified example.

[0052] In the first and second embodiments described above, a rod-shaped multicolor cosmetic molded body 20 was used as the multicolor solid molded body, which was created by attaching powder cosmetic 11 to the circumferential surface of a cylindrical powder cosmetic molded body 10.

[0053] However, the present invention is not limited to this; any multi-color cosmetic molded body in which the color of the powder cosmetic molded body 10 and the color of the differently colored powder cosmetic 11 are adjacent in cross-sectional view can be applied as a multi-color cosmetic molded body of the present invention.

[0054] For example, instead of the multi-color cosmetic molded body preparation step S2 in the first and second embodiments described above, the process may include a step to prepare a multi-color cosmetic molded body 21 by attaching a powder cosmetic 11, which is a different color from the powder cosmetic molded body 10, to the powder cosmetic molded body 10.

[0055] Therefore, for example, as shown in Figure 12(a), a multicolor solid molded body 21 is formed by attaching powder cosmetic 11, which is a powder cosmetic molded body, to a powder cosmetic molded body 10 so that its cross-section is crescent-shaped, or as shown in Figure 12(b), a multicolor solid molded body 22 is formed by attaching powder cosmetic 11, which is a powder cosmetic molded body, to a powder cosmetic molded body 10 so that its cross-section is checkerboard-shaped, can be applied as a modified example of the multicolor solid molded body 20 to create a multicolor solid cosmetic having a crack-like pattern.

[0056] The ratio of powder cosmetic molded body 10 to powder cosmetic molded body 11 may be equal, as shown in Figures 12(a) and (b), or it may be configured to have a difference, and is not particularly limited.

[0057] It should be noted that the present invention is not limited to the above embodiments, and various modifications and changes are possible within the scope of the gist of the invention.

[0058] For example, in the above embodiment, it was explained that when slicing or mincing the multicolor solid molded body 20, various crack patterns can be created by changing the cutting direction. However, various patterns can be created not only by slicing and mincing, but by any known cutting method. Furthermore, by changing the cutting width, the cutting angle relative to the multicolor solid molded body, etc., the thickness and shape of the fragments can be changed, thereby changing the pattern of the multicolor solid cosmetic.

[0059] Furthermore, in the above embodiment, the solid cosmetic 10 was formed into a rod shape and the multi-color solid molded body 20 was set into a rod shape in the solid cosmetic forming step S1 and the multi-color body creation step S2 in order to facilitate and efficiently perform the cutting work in the subsequent cutting step S3, but the present invention is not limited to this. Multi-color solid molded bodies in spherical or other three-dimensional shapes are also included in the scope of the present invention. [Explanation of Symbols]
