Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for solidifying powdered cosmetics of multiple types with different tones in a single cosmetic container without partitions with clearly defined boundaries. The present invention relates to a method for producing a multicolor solid cosmetic that can be easily applied.

[Prior art]

Conventionally, as a method of filling and solidifying multiple types of powdered cosmetics in a single cosmetic container without partitions with clearly defined boundaries, for example, Japanese Patent Application Laid-Open No. 59-44205 and Japanese Patent Application Laid-Open No. 59-44205, - What is shown in the ieio publication etc. is known. That is, in the former method, powdered cosmetics are filled in each space divided by a partition, preliminary pressing is performed, and then main pressing is performed with the partitions removed. On the other hand, in the latter method, powder cosmetics are filled into the space formed by the negative pressing piece out of a plurality of pressing pieces, pre-pressing is performed using another pressing piece, and then the other pressing piece is pressed. The powdered cosmetic is filled into the space formed by the above, preliminary pressing is performed using a negative pressing mold, and then main pressing is performed using a shaping mold.

[Problem that the invention seeks to solve]

However, in the conventional methods described above, the powdered cosmetic is filled in the powdered state and then molded by preliminary pressing and main pressing, so the following time-consuming process is required. There was a point.

First, although containers for cosmetics are usually small, dividing them into multiple small-area compartments and directly filling powdered cosmetics into these compartments not only has poor workability; Since it is a powder, it easily scatters to the surrounding area due to slight changes in movement, etc., and there is a problem that it mixes with other compartments and causes color mixing.

Second, a powder molded product is first made by preliminary pressing, and then this powder molded product is transferred to another female die, or the main press is performed using another male die or leveling die, so the pressing process is difficult. There is a problem in that the manufacturing process becomes extremely complicated, such as requiring many and various types of press molds.

Thirdly, the former method according to JP-A-59-44205 removes the partition after preliminary pressing, and the latter method according to JP-A-61-1610 also uses one of the pressing mold pieces to remove the partition. After preliminary pressing, the other mold piece is lifted upward and powdered cosmetics are filled, and the next preliminary pressing is performed. As a result, in both methods, the partition or mold piece is removed after the powder molded product has been pre-pressed, so the powder molded product loses its shape when these are removed, making the work extremely difficult. In addition to being difficult, there is a problem in that the yield of the product is poor.

The present invention was developed in view of the problems of the conventional methods described above, and instead of using powdered cosmetics directly, it uses a fluid liquid (slurry-like material) made by dispersing powdered cosmetics in a volatile solvent. By filling a frame or mold in advance to form a solid product, arranging the solid product in a cosmetic container, and performing a finishing press, the color mixing phenomenon can be eliminated, and the number of processes can be reduced by making the pressing process only a finishing press. To provide a method for producing a multicolored solid cosmetic packed in a container, which minimizes the number of press molds required.

[Means for solving problems]

In order to solve the above problems, the present invention provides a step of disposing a drying container in a frame or mold and filling it with a fluid liquid made by dispersing powdered cosmetics in a volatile solvent, and dispersing the volatile solvent. A step of solidifying the powdered cosmetic by dispersing it, a step of combining the thus formed solid powdered cosmetics of multiple colors and arranging them in a cosmetic container, and a step of placing the cosmetic container in a mold to It consists of a step of final pressing the solid powder cosmetic in the cosmetic container.

[Effect]

First, a volatile solvent is added to a powdered cosmetic, and a fluid liquid is prepared in advance for each color by stirring and mixing to form a slurry. Then, place the drying container in a drying frame or mold.In this case, this frame or mold may be prepared in only different colors, or one frame or mold may be used while changing the color sequentially. ), fill with fluid liquid of each color. Next, in order to release the volatile solvent from the filled fluid liquid, the powdered cosmetic is solidified by hot air drying, heat irradiation drying, or the like. Next, the thus formed solid powder cosmetics of multiple colors are cut into predetermined dimensions as required, and then the solid cosmetics of each color are combined and arranged in a cosmetic container. Furthermore, by placing the cosmetic container in the female mold and lightly tapping the surface of the solidified powder cosmetic with the male mold for final pressing, we produce a multicolored solid cosmetic packaged in a container with clear boundaries. can do.
