Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for producing pressed cosmetics in which cosmetics of a plurality of colors are accommodated in a compact tray without being separated by partition walls.

[Conventional technology]

Recently, many types of pressed cosmetics have been provided in which solid cosmetics of multiple colors are stored directly adjacent to each other in a tray without providing a partition wall.

These types are roughly divided into those with a small proportion of one unit for each color and those with a large proportion.
As an example of the former, the one described in JP-A-60-38311 is known, and as an example of the latter, the one shown in FIG. 17 is commercially available.

The method disclosed in Japanese Patent Application Laid-open No. 60-38311 discloses that powder pigments or powder pigments are mixed with a binder to form particles with a particle size of 0.02.
A base material formed into aggregates with a diameter of mmφ to 5 mmφ and a main material formed with a binder formed into aggregates with a particle size of 0.02 mmφ to 5 mmφ are placed in the same container. The main material and the base material form a mosaic pattern.

Then, use a makeup brush to mix each color to form the desired tone and apply makeup.

The one shown in Fig. 17 is one in which solid cosmetics A, B, and C of three colors are pressed directly adjacent to each other without being separated by a partition wall in a compact tray.
The manufacturing method is to partition the inside of the tray with a filling partition, then fill and press each of the three colors separately.
After that, the filling partition wall is removed.

And when using, use each color alone,
Or make up by mixing adjacent items at the boundary.

[Problem that the invention seeks to solve]

However, in the product described in JP-A No. 60-38311, the mixture of the base material and the main material differs each time it is manufactured, and the pattern of the resulting cosmetic also differs depending on the product, resulting in the same pattern. It is not possible to provide large quantities of such products, which causes problems in sales.

In addition, the fact that products with the same pattern cannot be produced means that the color tones obtained by blending with makeup brushes will also vary depending on the individual, and users can purchase any brush to obtain the desired color tone. There is also the problem that it is not possible to distinguish between objects.

Furthermore, the method shown in FIG. 17 has the problem that each color of cosmetic has to be filled after being temporarily partitioned with a filling partition wall, and that each color cannot be filled at the same time, which is time-consuming. This is a cause of high costs.

The present invention has been made in view of the above points, and makes it possible to mass-produce solid cosmetics in which at least two colors of solid cosmetics are directly adjacent to each other in a saucer without providing a partition wall in the same pattern. The technical challenge is to make it easier to manufacture.

[Means for solving problems]

In order to solve the above-mentioned technical problem, the present invention provides the following technical means when producing a press cosmetic in which solid cosmetics of at least two colors are directly adjacent to each other without using partition walls to form a color-coded pattern. I took it.

That is, a basic raw material of a single color is extruded by a bead molding machine to form a single color rod-shaped compressed ball 1 of several colors arbitrarily. Next, the monochromatic rod-shaped compressed beads 1 molded for each of several colors are divided in the axial direction to form compressed divided beads 2, and the compressed divided beads 2 of different colors are combined according to the desired pattern. Then, the combined compressed divided beads 2 are further squeezed and extruded using a centering molding machine to form a multicolored rod-shaped solid cosmetic 3. Finally, this multi-colored bar-shaped solid cosmetic material 3 is cut in the direction orthogonal to its axis to obtain a multi-colored plate-like solid cosmetic material 4, and this multi-colored plate-shaped solid cosmetic material 4 is pressed into a saucer 5. do.

In addition, as another means, instead of dividing the monochromatic rod-shaped compressed ball 1 molded in the above process, unlike the above process, it is further squeezed with a centering machine to form a monochromatic rod-shaped cosmetic. The bar-shaped cosmetics are combined according to the desired pattern with different colors, and the combined bar-shaped cosmetics are further squeezed and extruded using a centering molding machine to form a multi-colored bar-shaped solid cosmetic 3. It is also conceivable to process the multicolored bar-shaped solid cosmetic 3 in the same manner as in the above steps.

[Effect]

Each of the monochromatic rod-shaped compressed beads 1 is divided in the axial direction to form compressed divided beads 2, and the compressed divided beads 2 of different colors are combined according to the desired pattern, or the single-colored rod-shaped compressed beads 1 are divided. Instead, it is further squeezed with a centering machine to form a single-colored bar-shaped cosmetic, and then this single-colored bar-shaped cosmetic is combined with different colors according to the desired pattern, and then squeezed with a centering machine. Since the multicolored bar-shaped solid cosmetic material 3 is formed by extrusion, if this bar-shaped solid cosmetic material 3 is cut in the direction orthogonal to the axis, the color-coded pattern appearing on the cut surface will always be the same.

Then, during manufacturing, it is only necessary to press-form the plate-shaped solid cosmetic 4 formed by cutting multi-colored bar-shaped cosmetics into the saucer 5, so there is no need for filling operations for each color, and only one filling operation is required. That's enough.

Furthermore, among the two methods, the former uses the bead molding machine and the centering machine only once each to divide the rod-shaped compression ball 1, whereas the latter uses centering molding without dividing the rod-shaped compression ball 1. Since the diameter is made small with the machine and then reassembled, the centering machine is used twice.
Therefore, the former is easier to manufacture. By the way, in the former method, in order to divide the rod-shaped compressed balls 1, as shown in FIG. It is preferable that it is automatically divided during extrusion by a machine.

Here, since the cosmetics constituting the multicolor pressed cosmetics according to the present invention have at least two colors, any number of colors may be used, and in this case, a plurality of areas of the same color may be provided. Furthermore, the method of combining the single-color bar-shaped cosmetics squeezed using the compressed split ball 2 or the centering machine is arbitrary, as shown in Figures 5 to 16, and depends on the desired pattern to be obtained. The color and cross-sectional shape of the compressed divided beads 2 and single-color rod-shaped cosmetics to be combined are selected, and an arbitrary color-coded pattern is formed.

In addition, the colors of adjacent solid cosmetics are
It is best to use colors that produce a beautiful color when mixed with each other, and it is also preferable to use colors from the same color family, such as dark blue and light blue, because when mixed, you can obtain an intermediate color between them. be.

When mixing adjacent colors, the cosmetic brush of the present invention does not have a partition wall to block them, so it is only necessary to move the cosmetic brush back and forth across both areas of the two colors to be mixed.

In addition, solid cosmetics include eye shadow, foundation, cheek red, etc., and eye shadow of multiple colors may be formed as in the present invention, or the present invention may be formed as a combination of eye shadow and cheek red. You may.

Furthermore, the basic raw materials that make up this solid cosmetic are coloring agents such as extender pigments such as mica, talc, and sericite, inorganic pigments such as iron oxide and titanium oxide, and cosmetics such as Red No. 202, Red No. 226, and Yellow No. 4. tar pigments, mica titanium, pearling agents such as iron oxide treated mica titanium, preservatives as additives,
Surfactants, metallic soaps, water-soluble polymers, oils such as lanolin, vaseline, squalane, liquid paraffin, etc. are used, and solvents such as isoparaffin, ion-exchanged water, etc. are used.

Further, both the beading machine and the centering machine are extrusion machines, and a piston type extrusion machine is particularly suitable. The difference between a bead molding machine and a centering machine is that the diameter of the extrusion opening of the attached die is large or small. Furthermore, the required upper diameter to be compressed by squeezing is becoming smaller. Further, in any case, the inner diameter of the die is tapered so that the diameter decreases from the die inlet to the die outlet in order to apply compressive force to the molded product.

〔Effect of the invention〕

According to the present invention, compressed divided beads are formed by dividing monochromatic rod-shaped compressed beads in the axial direction, and compressed divided beads of different colors are combined according to a desired pattern, or single-colored rod-shaped compressed beads are combined in accordance with a desired pattern. Rather than dividing it into parts, it is further squeezed using a centering machine to form a single-color bar-shaped cosmetic, and then this single-colored bar-shaped cosmetic is combined with different colors according to the desired pattern and squeezed using a centering machine. Since a multicolored bar-shaped solid cosmetic was formed by extrusion and extrusion, if this bar-shaped solid cosmetic was cut in the direction orthogonal to the axis, the color-coded pattern appearing on the cut surface would always be the same. Therefore, pressed cosmetics with the same color-coded pattern can be manufactured and sold in large quantities, and there is no variation in the blending of each color during use, and as long as the cosmetics have the same pattern, the same color can always be blended. Therefore, consumers can surely select their favorite cosmetics without being confused about the selection of cosmetics.

During production, it is only necessary to press-form the plate-shaped solid cosmetic prepared by cutting multicolored bar-shaped cosmetics into the saucer, so there is no need to fill each color separately, and one filling operation is sufficient. , Therefore, the number of manufacturing steps is small and manufacturing can be done at low cost.

〔Example〕

<Example 1> A solvent-based press cosmetic was manufactured using the following basic raw materials.

(1) Powder part Mica……………25.0 (%) Talc……………5.0 Pearling agent…30.0 Inorganic pigment…10.0 (2) Oil Preservative…0.1 Surfactant…………1.0 Metallic soap…………1.0 Liquid paraffin……3.0 Vaseline…………1.0 (3) Isoparaffin……23.9 First, add the oil (2) to the powder part (1). In addition to this (3)
Add isoparaffin and knead with a kneader. Multiple colors are available by changing the color of the inorganic pigment,
Each color is extruded using a molding machine and has a diameter of 50 mm.
A monochromatic rod-shaped compressed ball 1 of ~80 mm is molded.

This rod-shaped compressed ball 1 is extruded and simultaneously split in the axial direction by a dividing tool 6 attached to a die extrusion port of a bead molding machine to form compressed split balls 2. After that, the compressed split balls 2 of different colors are combined and bundled into a rod shape, extruded with a centering molding machine, squeezed and compressed to form a cylindrical multicolored rod-shaped solid cosmetic 3 with a diameter of 20 to 30 mm. This is cut into a thickness of 2 to 5 mm in the orthogonal direction to obtain a multicolored plate-shaped solid cosmetic 4, which is then pressed into a saucer 5. This was then dried at 70°C to 90°C to obtain a product.

As shown in FIG. 3, the resulting pattern has a blue central square part, with red, pink, orange, and brown colors arranged around it corresponding to each side of the square.

<Example 2> In this example, a water-based pressed cosmetic was manufactured using the following basic raw materials.

(1) Powder part Mica……………20.0 (%) Talc…40.0 Inorganic pigment…5.0 Organic pigment…0.5 (2) Oil Preservative……… 0.1 Surfactant…1.0 Squalane…2.0 Lanolin…1.0 (3) Water-soluble polymer…0.5 (4) Ion-exchanged water…30.4 First, (1) The water-soluble polymer (3) is added to the powder part and mixed, the oil (2) is added, and the ion-exchanged water (4) is added thereto and kneaded. A plurality of colors were prepared by changing the colors of inorganic pigments and organic pigments, and then molded and pressed in the same manner as in Example 1, and dried at 100°C to 120°C to obtain a product.

<Example 3> Using the same raw materials as in Example 1, a pressed cosmetic was obtained in the following manner.

That is, after kneading the raw materials, a single-color rod-shaped compressed ball 1 is molded in any number of colors using a bead molding machine. Then, each rod-shaped compression ball 1 is further squeezed using a centering molding machine to form a single-color rod-shaped cosmetic having a diameter smaller than that of the rod-shaped compression ball 1. Next, a plurality of single-color bar-shaped cosmetics are collected and bundled to have the same diameter as the bar-shaped compressed ball 1, and squeezed again with a centering molding machine to form a multi-colored bar-shaped solid cosmetic 3. Thereafter, in the same manner as in Example 1, this multicolored bar-shaped solid cosmetic 3 was cut to form a multicolored plate-shaped solid cosmetic 4, which was pressed onto a saucer 5 and dried to obtain a product.

Note that the ratio and shape of each color region are adjusted by changing the thickness and shape of the compressed divided beads 2 and monochromatic bar-shaped cosmetics to be combined.
