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]

! Many pressed cosmetics are available that are housed directly adjacent to each other.

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.

In the method disclosed in JP-A-60-38311, powder pigments or powder pigments are mixed with a binder to form particles with a particle size of 0.0211.
A base material formed into aggregates of mφ to 5th order 1φ and a powder pigment of a different color tone from this base material are combined with a binder to form particles with a particle size of 0.
02xzφ~513! The main material formed into aggregates of φ is placed together in the same container and compression molded at the same time to prevent the aggregate state from being damaged, and the main material and base material form a mosaic pattern. It is something.

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

The one shown in Figure 17 has three
Solid cosmetics A, B, and C in colors are pressed directly adjacent to each other without separating them with a partition wall.The manufacturing method is to divide the inside of the tray with a filling partition wall, and then fill and press each of the three colors separately. Then, the filling partition wall is removed.

When used, each color can be used alone or by mixing adjacent colors at the border to create makeup.

[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. It cannot be provided in large quantities, which causes problems in sales.

In addition, the fact that it is not possible to create products with the same pattern means that the color tones obtained by blending with makeup brushes will also vary depending on the individual, and users are unsure which brushes to purchase to obtain the desired color tone. There also arises the problem that it cannot be determined.

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, and that it is time-consuming because each color cannot be filled at the same time. This is a cause of high costs.

The present invention has been made in view of these points, and it is therefore possible to mass-produce solid cosmetics with the same pattern, in which at least two colored solid cosmetics are placed directly adjacent to each other in a saucer without providing a partition wall. 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 method for producing a pressed cosmetic in which solid cosmetics of at least two colors are directly adjacent to each other without using a partition wall to form a color pattern. took technical measures.

That is, (1) A single-color basic raw material is extruded using a bead molding machine to form single-color rod-shaped compression strain l in any number of colors. ■Next,
The monochromatic compressed strain L formed for each of several colors is divided in the axial direction to form compressed cut soil 2, and the compressed cut soil 2 of different colors are combined according to the desired pattern.

■Then, Koko 1llI Kohaha Tobotomu Embroidery Kuji 1
-2-Sayama-No.- is squeezed and extruded to form a multicolored bar-shaped solid cosmetic 3. ■Finally, this multicolored bar-shaped solid cosmetic 3 is cut in the direction orthogonal to its axis to obtain a multicolored plate-shaped solid cosmetic 4, and this multicolored plate-shaped solid cosmetic 4 is placed in a saucer 5. Press.

In addition, as another means, instead of dividing the monochromatic rod-shaped compressively strained l formed in step ① above, unlike the step ② above,
Furthermore, a centering molding machine is used to squeeze the cosmetic into a single-color rod-shaped cosmetic.The single-colored rod-shaped cosmetics are then combined with different colors according to the desired pattern. It is also conceivable to squeeze and extrude the product to form a multi-colored bar-shaped solid cosmetic material 3, and to process this multi-colored bar-shaped solid cosmetic material 3 in the same manner as in step (2) above.

[Effect]

The compressed cut soil 2 is formed by dividing the monochromatic rod-shaped compressed strain 1 in the axial direction, and the compressed cut soil 2 of different colors are combined according to the desired pattern, or the single color 1 bottle of 1 male plastic is further squeezed using a centering machine to form a single-colored bar-shaped cosmetic, and the single-colored bar-shaped cosmetics are combined with different colors according to the desired pattern to form a core. Since the multi-colored bar-shaped solid cosmetic material 3 is formed by squeezing and extruding with a molding machine, if this bar-shaped solid cosmetic material 3 is cut from the direction perpendicular to the axis, the color 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.

Also, among the two methods, the former uses the doweling 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 reduced using a machine and then reassembled, the centering machine is used twice, and the former method is easier to manufacture. By the way, in the former method, in order to divide the rod-shaped compressed balls l, 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 compression splitting top 2 or the centering molding machine can be optionally used as shown in Figures 5 to 16, and the compression splitting top 2 or monochrome bar-shaped cosmetics to be combined depending on the desired pattern. Select the color and cross-sectional shape, and use any color to form a pattern.

In addition, it is best to use colors of adjacent solid cosmetics that will give a beautiful color when mixed with each other, and if they are of the same color family, such as dark blue and light blue, when mixed together, This is suitable because it is possible to obtain a color intermediate between them.

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 shadows, foundations, cheek reds, etc., and eye shadows of multiple colors may be formed as in the present invention, or the present invention may be used as a combination of eye shadow and cheek red. may be configured.

Furthermore, the basic raw materials that make up this solid cosmetic are: ■ Colorants such as extender pigments such as mica, talc, and sericite, inorganic pigments such as iron oxide and titanium oxide, and red No. 202, red No. 226, yellow No. 4, etc. Cosmetic tar pigments, mica titanium, iron oxide-treated mica titanium, and other pearl agents; additives such as preservatives, surfactants, metal soaps, water-soluble polymers; oils and fats such as lanolin, vaseline, squalane, liquid paraffin, etc. , ■ Use isoparaffin, ion-exchanged water, etc. as a solvent.

Further, both the beading machine and the centering machine are extrusion machines, and a piston type extrusion machine is particularly suitable. Section o+1 +, h of doweling machine and centering machine

The diameter of the ball is large in the ball rolling machine, and the required upper diameter for compressing the rod-shaped compression ball L formed by the ball rolling machine is smaller in the centering machine.

Furthermore, in any case, the inner diameter of the goo is tapered so that the diameter decreases from the gouie inlet to the gouie outlet in order to apply compressive force to the molded product.

〔Effect of the invention〕

According to the present invention, monochromatic rod-shaped compressed balls are each divided in the axial direction to form a compressed divided top, and the compressed divided tops of different colors are combined according to the desired pattern, or the single-colored rod-shaped compressed balls are combined in accordance with the 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 multi-colored bar-shaped solid cosmetic is formed by extrusion and extrusion, if this bar-shaped solid cosmetic is cut in the direction orthogonal to the axis, the color pattern appearing on the cut surface will always be the same. Therefore, for the same color, a large amount of pattern press material is used! At the same time, it is possible to always mix the same color as long as there is no variation in the mixing of each color during use and the pattern is the same. 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 (it can be manufactured at low cost).
