Description

[Detailed description of the invention]

The present invention relates to a method for producing a multicolored solid powder cosmetic having portions of different colors (different tone, shade, and gloss) in a single container. Here, the solid powder cosmetic refers to a so-called compact cosmetic that is compressed after filling a container or an inner tray with a powder cosmetic mainly consisting of powder. Conventionally, in this type of solid powder cosmetics,
If two or more solid powder cosmetic parts of different colors are provided in a single container to create text or picture patterns based on the different colors, there may be a slight restriction on the
The only known method was disclosed in Publication No. 19663. This method involves filling powdered cosmetics of different colors in each partitioned space into a distribution pan with fixed partitions, and then distributing the powder into a distribution pan with the same shape and dimensions as the distribution pan. This is a method of filling powdered cosmetics into a tray by extruding and transferring the powder into a fixed tray. Therefore, in the case of such a method, a partition is fixed in a single container, such as a saucer, and the cosmetics are separated by the partition. Such partitions are exposed to the outside when using cosmetics.
As they protrude, the product value is significantly diminished, and it is also impossible to mix adjacent cosmetics with an applicator such as a brush. Therefore, the easiest way to solve the drawbacks observed in the known manufacturing methods of multicolor solid powder cosmetics is to remove the partitions inside the container, but simply removing the partitions will not lead to the following problems: I had a problem like this. That is, since the cosmetics filled in powder form adhered to the partitions, there was a risk that the cosmetics would break or the edges would be chipped when the partitions were removed. Such cracks and chips in cosmetics significantly impair commercial value, making it no longer possible to provide them as commercial products. Furthermore, when the partitions are formed into complicated shapes to form pictures or letters, it becomes extremely difficult to uniformly fill the partitioned space with cosmetics, making it unsuitable for mass production. Furthermore, there was also the problem that the powder was scattered during the filling of the cosmetic and caused color mixing. The present invention has been made to solve these drawbacks and problems, and it is possible to partition a plurality of spaces by removably installing partitions that can form desired characters or pictures inside a single container. Each partitioned space is filled with slurry of different colors made of one or more solvents and powdered cosmetics, and after filling, the cosmetics are compressed using a molding head made of a porous material. The present invention is characterized in that the solvent is removed by suction during molding, and then the partitions are removed, and then further compression molding is performed to eliminate the gaps between the cosmetics caused by the removal of the partitions. In this way, the present invention allows the partition to be freely inserted, the cosmetic is dissolved in a solvent and filled as a slurry, and after the partition is removed, the cosmetic is compression molded. It is possible to easily and reliably fill containers with multicolored solid powder cosmetics and provide a method suitable for mass production. In addition, since the cosmetic to be filled is a slurry, it can be filled without any problems even if the partition has a complicated shape, and there is no risk of color mixing. There is no longer any fear that the parts will be missing. Furthermore, the gaps between the cosmetics that occur due to the removal of the partitions are also eliminated by recompression molding after the partitions are removed, and the cosmetics become continuously connected. ,
Adjacent cosmetics can be mixed together using an applicator such as a brush, and the benefits of filling a single container with multicolored powder cosmetics can be maximized. Furthermore, according to the present invention, the solvent is removed by suction at the same time as the filled cosmetic is compression-molded using a molding head made of a porous material. As the air mixed in the cosmetic is removed, the cosmetic can be molded and solidified in an extremely good condition, increasing its strength against external impacts and preventing the cosmetic from cracking or cracking. can be effectively prevented. Hereinafter, the configuration of the present invention will be explained in detail. The solvent used in the present invention may be any general solvent, but ethyl alcohol, isopropyl alcohol, low-boiling hydrocarbons, silicone oil, cyclic silicone, or water are preferred. The powder constituting the powder cosmetic used in the present invention is a powder commonly used in the cosmetic field, and examples include extender pigments such as talc, kaolin, mica, and titanium dioxide, and iron oxides such as red, yellow, and black. , ultramarine blue, navy blue, chromium pigments, organic pigments (for example, Red No. 226, Blue No. 404, Yellow No. 401, etc.). In order to enhance the finish effect of these cosmetics, we use fish scale foil as a natural pearl agent, titanium-mica synthetic pearl pigment, titanium-mica-organic pearl pigment, titanium-mica-iron oxide pearl as synthetic pearl agents. Pigments, titanium-mica-prussian (chromium oxide) based pearl pigments, etc. can be added. In the present invention, the powder contains other components constituting the powder cosmetic, such as oil, water-soluble polymer,
Water-swellable clay minerals, preservatives, appropriate drugs, fragrances,
Surfactants, antioxidants, chelating agents, ultraviolet absorbers, etc. may be optionally added. The mixing ratio of the above-mentioned solvent and powder cosmetic may be appropriately selected within a range in which the slurry obtained by mixing has suitable hardness and fluidity for filling, and varies depending on the type of solvent and powder. In the present invention, two or more types of slurry made of the above-mentioned solvent and powdered cosmetic are prepared, each having a different color.
After this is supplied to each space divided by a partition that is removably inserted into the container and forms a desired character or picture pattern, compression molding is performed using a molding machine having a molding head made of a porous material. Porous resin, sintered metal, or the like can be used as the porous material. Preferably, the resin forming the porous resin is an acrylonitrile copolymer, and the metal forming the sintered metal is preferably stainless steel, copper, or an alloy of copper. In the present invention, at the same time as the compression molding, the solvent contained in the slurry is removed by suction from the back surface of the molding head (the surface opposite to the slurry to be compression molded).
By suction removal, the solvent in the cosmetic can be completely removed, and as the solvent is removed, the air mixed in the cosmetic is also removed, resulting in better molding and solidification of sludge compared to simple compression molding. As the strength increases, the occurrence of cracks and cracks due to impact is significantly reduced. The compression and suction process described above can be carried out according to the conditions of ordinary compression molding, except for the use of a porous material and the suction of the solvent. Insert an absorbent material such as sponge, paper, cloth, or non-woven fabric between the container and the slurry, or fill the container slightly more than its capacity in anticipation of the volume of the slurry decreasing as the solvent dries. Alternatively, this can be done efficiently by applying a slight vibration after filling the slurry to make the slurry blend into the container. Furthermore, manufacturing becomes more efficient if the absorbent body is formed into a sheet and is wound up one after another in an endless manner by a winding device. In the present invention, after the compression molding and the suction of the solvent, the partition is removed. After removing the partitions, compression molding is performed again to fill in the area where the partitions were removed and to make the cosmetics continuous. Further, if suction of the solvent through the molding head is not sufficient to dry the slurry, drying may be performed as a final step. Drying may be carried out by any method such as leaving to dry in the air, heating, blowing air, etc., as long as it does not have an adverse effect such as odor on the intended multicolor solid powder cosmetic. For the purpose of understanding the invention, the compression process and solvent suction are schematically illustrated in FIG. 1

Fill in 0, 11, 12. Thereafter, using the apparatus shown in FIG. 5, the solvent is removed by suction simultaneously with the compression molding of the slurry, and then the partitions 20 and 21 are removed. Thereafter, the gap created by the removal of the partitions 20 and 21 is filled by recompression molding, and the gap disappears.
