FIG. 2 is a perspective view showing steps (5) and (6) in the manufacturing method of the present invention.

[1] Solid Cosmetic The solid cosmetic of the present invention is a solid cosmetic having at least two-layer regions, and has at least one two-layer region that is not in contact with the frame of a cosmetic container.
As described above, to the best of the inventors' knowledge, a solid cosmetic having a "two-layer region that is not in contact with the frame of a cosmetic container" has not been developed. Although not limited thereto, a "two-layer region that is not in contact with the frame of a cosmetic container" can be produced by the manufacturing method of a solid cosmetic described below.
The solid cosmetic product of the present invention may be composed of only a two-layer region, but has at least one two-layer region that is not in contact with the frame of the cosmetic container.

The solid cosmetic product of the present invention preferably has a single-layer region and a two-layer region, and has a single-layer region adjacent to the two-layer region that is not in contact with the frame of the cosmetic container. The two-layer region that is not in contact with the frame of the cosmetic container more preferably has a single-layer region around it. Note that the solid cosmetic product of the present invention may also include a form having a two-layer region around a single-layer region.

The two-layer region of the solid cosmetic product of the present invention comprises an upper layer and a lower layer. In one embodiment of the present invention, (1) the lower layer is continuous with the adjacent single-layer region. In another embodiment of the present invention, (2) the upper layer is continuous with the adjacent single-layer region. The solid cosmetic product of the present invention may contain either embodiment (1) or embodiment (2) alone, or may contain both embodiment (1) and embodiment (2).

A specific explanation will be given using the solid cosmetic product of the present invention shown in Figure 1. The solid cosmetic product of Figure 2 has a two-layer region (1) in the shape of a "moon," two two-layer regions (2) and (3) in the shape of a "star," one large and one small, and two two-layer regions (4) and (5) in the shape of a "bird," indicated by two dashed lines. The two-layer regions (4) and (5) in the shape of a "bird" are formed by pouring the raw materials of the solid cosmetic product onto the lower layer of the bird shape, as shown in Figure 2, and then molding the upper layer.
None of the two-layer regions (1) to (5) are in contact with the frame of the cosmetic container. Each of the two-layer regions (1) to (5) is adjacent to a single-layer region and is surrounded by the single-layer region. The lower layer portions of the two-layer regions (1) to (3) are continuous with the adjacent single-layer regions, forming single-layer regions continuous from the two-layer regions. On the other hand, the upper layer portions of the two-layer regions (4) and (5) are continuous with the adjacent single-layer regions, forming single-layer regions continuous from the two-layer regions.
When the solid cosmetic preparation of the present invention is composed of only a two-layer region, it can be produced, for example, by changing the single-layer region of FIG. 1 into a two-layer region in which the upper and lower layers have the same shape.

The surfaces of the single-layer region and the double-layer region may be flat, or may have projections and recesses. If the surfaces have projections and recesses, the projections and recesses may follow the shape of the single-layer region or the double-layer region, or may be projections and recesses that mold a shape in the single-layer region, or may be projections and recesses that mold a shape in the double-layer region. The projections and recesses can be molded, for example, by compression molding.

As long as the solid cosmetic product of the present invention has a single-layer region and a double-layer region, it is not particularly limited, but examples thereof include blush, face powder, highlighter, eyebrow, foundation, bronzer, and eye shadow. The shape of the solid cosmetic product of the present invention when viewed from above is not particularly limited, but examples thereof include rectangle, square, circle, oval, decagon, nonagon, octagon, heptagon, hexagon, pentagon, square, star, heart, teardrop, and triangle.

The color tone of the solid cosmetic product of the present invention can be appropriately selected depending on the type of cosmetic product. Different color tones may be selected for the single-layer region and the two-layer region. Different color tones may be selected within the single-layer region or the two-layer region. Furthermore, the same color tone may be selected for the single-layer region and the two-layer region.

[2] Manufacturing Method of Solid Cosmetics The manufacturing method of the solid cosmetics of the present invention includes: (1) a step of filling a first molding unit with a solid cosmetic raw material and producing a first molded product by compression molding (hereinafter, sometimes referred to as step 1); (2) a step of inserting the first molded product into a cosmetics container (hereinafter, sometimes referred to as step 2); (3) a step of filling a second molding unit with a solid cosmetic raw material and producing a second molded product by compression molding (hereinafter, sometimes referred to as step 3); (4) a step of inserting the second molded product into the cosmetics container from above the first molded product (hereinafter, sometimes referred to as step 4); (5) a step of filling the cosmetics container into which the first molded product and the second molded product have been inserted with a solid cosmetic raw material (hereinafter, sometimes referred to as step 5); and (6) a step of compression molding the solid cosmetic raw material in the cosmetics container (hereinafter, sometimes referred to as step 6).

《Process 1》
In the above-mentioned step 1, a solid cosmetic raw material is filled into a first molding unit, and a first molded product is produced by compression molding.
The solid cosmetic raw material is mainly composed of, but not limited to, a powder and an oil component, which will be described later. The powder and the oil component are mixed to prepare a slurry-like dispersion liquid.
The powder content in the first molded product is not particularly limited, but the lower limit is, for example, 60% by weight or more, preferably 70% by weight, and more preferably 80% by weight. The upper limit is, for example, 95% by weight, preferably 90% by weight, and more preferably 85% by weight. The lower limit and the upper limit can be appropriately combined.
The oil content in the first molded product is not particularly limited, but the lower limit is, for example, 5% by weight or more, preferably 15% by weight, and more preferably 20% by weight. The upper limit is, for example, 40% by weight, preferably 35% by weight, and more preferably 25% by weight. The lower limit and the upper limit can be appropriately combined.

The dispersion liquid further contains a solvent in addition to the powder and the oil. By containing the solvent, it is possible to easily mix the powder and the oil and obtain a mixture suitable for producing a first molded product.
The solvent is not particularly limited, but examples thereof include ethanol, water, acetone, cyclopentasiloxane, isopropanol, hydrogenated polyisobutene, and isododecane. The content of the solvent is, for example, 30 to 60% by weight, and preferably 40 to 50% by weight, of 100% by weight of the dispersion. Since most of the solvent is volatilized by compression molding, the main contents of the first molded product are the powder and oil.

The dispersion is filled into a first molding unit. The first molding unit preferably has partitions for each region, but is not limited thereto, in order to form a plurality of single-layer regions and/or a plurality of two-layer regions. The dispersion is filled into the first molding unit preferably, but is not limited thereto, from the lower or upper part of the partitioned region of the first molding unit. However, the first molded product in contact with the frame of the cosmetic container can be filled from the side.
The dispersion liquid filled in the first molding unit is compression molded to produce a first molded product. The method of compression molding is not particularly limited.

As the first molded product in step (1), a single-layer region, a lower layer of a two-layer region, or a single-layer region and a lower layer of a two-layer region can be produced, but preferably a single-layer region and a lower layer of a two-layer region. In the case of a lower layer of a two-layer region, the lower layer can be formed into a concave shape by compression molding, as shown in "Steps 1 and 2" in Figure 2. By making it into a concave shape, it becomes easy to mold the upper layer of the two-layer region on top of it. Furthermore, when the obtained solid cosmetic product consists only of a two-layer region, it is preferable to produce the first molded product in step (1) as the lower layer of a two-layer region.

《Process 2》
In the step 2, the first molded article is inserted into the cosmetic container. The method of insertion into the cosmetic container is not particularly limited, but for example, the molded first molded article can be inserted into the cosmetic container by dropping it from the top of the first molding unit ("Steps 1 and 2" in FIG. 2).
The cosmetic container is not particularly limited as long as it can accommodate the molded product, but examples thereof include a metal plate, a resin plate, or a paper plate.

《Process 3》
In the step 3, the solid cosmetic raw material is filled into the second molding unit and compressed to produce a second molded product. Using the solid cosmetic raw material, a slurry-like dispersion liquid can be prepared in the same manner as in the step 1.
The dispersion is filled into a second molding unit. The second molding unit preferably has partitions for each region in order to form a plurality of single-layer regions and/or a plurality of two-layer regions, but is not limited thereto. The dispersion is filled into the second molding unit preferably from the lower or upper part of the partitioned region of the second molding unit, but is not limited thereto.
The dispersion liquid filled in the second molding unit is compression molded to produce a second molded product. The method of compression molding is not particularly limited.

As the second molded product in step (3), a single-layer region, or an upper layer of a two-layer region and/or a lower layer of a two-layer region can be produced. If the obtained solid cosmetic product consists only of a two-layer region, as the second molded product in step (3), an upper layer of a two-layer region and/or a lower layer of a two-layer region is produced.

《Step 4》
In step 4, the second molded product is inserted into the cosmetic container. The method of insertion into the cosmetic container is not particularly limited, but for example, the molded second molded product can be inserted into the cosmetic container by dropping it from the top of the second molding unit (steps 3 and 4 in FIG. 2).
In addition, when the second molded object is the upper layer of the two-layer region, it can be inserted into the upper part of the lower layer of the two-layer region having a concave shape formed by compression molding, like the "moon" or the large and small "stars" shown in "Steps 3 and 4" of Fig. 2. In addition, when the second molded object is the lower layer of the two-layer region, it can be directly inserted into the cosmetic container, like the two "birds" shown in "Steps 3 and 4" of Fig. 2.

《Step 5》
In step 5, the cosmetic container into which the first molded article and the second molded article have been inserted is filled with a solid cosmetic material.
The solid cosmetic raw material is mainly composed of, but not limited to, a powder and an oil component, which will be described later. The powder and the oil component are mixed to prepare a slurry-like dispersion liquid.
The content of the powder in the solid cosmetic raw material is not particularly limited, but the lower limit is, for example, 60% by weight or more, preferably 70% by weight, and more preferably 80% by weight. The upper limit is, for example, 95% by weight, preferably 95% by weight, and more preferably 85% by weight. The lower limit and upper limit can be appropriately combined.
The content of oil in the solid cosmetic raw material is not particularly limited, but the lower limit is, for example, 5% by weight or more, preferably 15% by weight, and more preferably 20% by weight. The upper limit is, for example, 40% by weight, preferably 35% by weight, and more preferably 25% by weight. The lower limit and upper limit can be appropriately combined.
The dispersion liquid further contains a solvent in addition to the powder and oil. By including a solvent, it is possible to easily mix the powder and oil and obtain a mixture suitable for producing a solid cosmetic preparation .
The solvent is not particularly limited, but examples thereof include ethanol, water, acetone, cyclopentasiloxane, isopropanol, hydrogenated polyisobutene, and isododecane. The content of the solvent is, for example, 30 to 60% by weight, and preferably 40 to 50% by weight, based on 100% by weight of the dispersion. Note that, since most of the solvent volatilizes due to compression molding, the main contents of the solid cosmetic are the powder and oil.

The solid cosmetic raw material to be filled is a solid cosmetic raw material for forming a single-layer region, an upper part of a two-layer region, or a single-layer region and an upper part of a two-layer region, but is preferably a single-layer region and an upper part of a two-layer region. In the case of a single-layer region, the dispersion is filled in the region of the cosmetic container in which the first and second molded products are not inserted, as shown in "Steps 3 and 4" in Figure 2. In the case of an upper part of a two-layer region, the dispersion is filled above the lower part of the two-layer region inserted as the second molded product ("Steps 3 and 4" and "Step 5" in Figure 2). In addition, if the obtained solid cosmetic consists only of a two-layer region, it is preferable that the solid cosmetic raw material in step (5) is used to create the upper part of the two-layer region.

《Step 6》
In step 6, the solid cosmetic raw material in the cosmetic container is compression molded. The compression molding method is not particularly limited. A pattern can be applied to the solid cosmetic raw material (dispersion liquid) filled in step 5 by compression molding ("step 6" in Figure 2). In addition, the shapes of the single-layer region and double-layer region of the first molded object and the second molded object inserted up to step 4 can be adjusted. Compression molding includes wet molding. The wet molding method is a method in which a slurry-like solid cosmetic raw material is pressed, and then the solvent is dried and evaporated to form a shape.

Example 1
In this example, a solid cosmetic preparation was produced according to the steps shown in FIGS.
To produce the first molded products "Blue Sky (1)", "Golden Star (2)", "Pink Star Tail (4)", and "Blue Star Tail (3)", slurry dispersions were prepared with the compositions shown in Tables 1 to 4.

The resulting slurry-like dispersants were filled into the first molding unit from the filling pump, and the first molded products were obtained by compression molding. The resulting first molded products were dropped into a metal dish (10).

Next, to prepare the second molded products "Golden Moon (5)", "Golden Star (Large) (6)", "Golden Star (Small) (7)", "Blue Bird (8)", and "Pink Bird (9)", the slurry dispersion was adjusted to the composition shown in Table 2. The composition of the "Golden Moon" etc. is the same as that of the "Golden Star", the composition of the "Blue Bird" is the same as that of the "Blue Sky", and the composition of the "Pink Bird" is the same as that of the "Pink Star Tail".
The obtained slurry-like dispersants were filled into a second molding unit from a filling pump, and each was compressed to obtain a second molded product. The obtained second molded products were dropped into a metal plate (10).

Next, in order to prepare a "white cloud (11, 12)" as a third molded object in the metal plate into which the first and second molded objects had been inserted, a slurry dispersion was prepared with the composition shown in Table 3. The composition of the "white cloud" is the same as that of the "golden star" described above.
The obtained dispersion was filled on top of the second molded products "Blue Bird" and "Pink Bird". Solid cosmetic preparations were obtained by wet molding.

The solid cosmetic product of the present invention can be used as a blush, face powder, highlighter, eyebrow, foundation, bronzer, or eyeshadow.
