Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a multi-layered cosmetic in which a plurality of types of solid cosmetics with different colors are filled and molded in a desired arrangement state in a single tray without a partition plate. The present invention relates to a method for producing colored solid cosmetics.

[Prior art]

Conventionally, methods for filling and solidifying multiple types of powdered cosmetics in a single container without partitions with clearly defined boundaries have been disclosed, for example, in JP-A-59-44205 and JP-A-61-1610. The ones shown in Publication No. 1, etc. are known. That is, in the former method, a powder cosmetic is filled into each space divided by a partition, preliminary pressing is performed, and then main pressing is performed with the partition removed. On the other hand, in the latter method, powder cosmetics are filled into the space formed by one of the plurality of pressing pieces, preliminary pressing is performed using the other pressing piece, and then the other pressing piece is pressed. A powder cosmetic is filled into the space formed by the above, and preliminary pressing is performed using one pressing mold piece, and then main pressing is performed using a shaping mold.

[Problem that the invention seeks to solve]

According to the above-mentioned conventional method, although the cosmetic receptacle is small, it is divided into a plurality of small-area sections using partitions or pressed pieces, and powdered cosmetics are directly applied to each of the small-area sections. Since the method involved quantitative filling, then preliminary pressing, and then main pressing, the following problems arose.

First, there is a problem in that accurately weighing a very small amount of powder and directly filling a small-area compartment with the weighed powder has poor workability and is unsuitable for mass production.

Second, the powder of powdered cosmetics is easily scattered around due to slight changes in movement, and it mixes with other compartments, resulting in color mixing.

Thirdly, solid powder cosmetics need to be easy to remove with a puff, brush, etc., and have good spreadability and adhesion when applied to the skin, so they easily lose their shape. Despite this, the former method disclosed in JP-A No. 59-44205 removes the partition after preliminary pressing, and the latter method according to JP-A No. 61-1610 also uses one pressing piece. After the first preliminary pressing, the other mold piece is lifted upward and powdered cosmetic is 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.
When removing these, the powder molded product loses its shape, which not only makes the work extremely difficult, but also
The problem is that the product yield is poor.

The present invention has been made in view of the problems of the conventional methods described above. Then, the molded solid cosmetics of each color are transferred from the frame into the tray in the desired arrangement state, and a final pressing process is performed, thereby making it possible to automate and mass-produce multicolored solid cosmetics. Moreover, color mixing between color sections is eliminated to form clear sections, and solid cosmetics of each color are transferred directly from the frame into the saucer, thereby eliminating deformation.

[Means for solving problems]

The means of the present invention configured to solve the above-mentioned problems is to mold solid cosmetics in a plurality of colors by filling powder cosmetics into a hollow cylindrical frame with openings on both upper and lower sides. The molded solid cosmetics of each color are transferred from the frame into a saucer, and the solid cosmetics of a plurality of colors transferred and arranged in the saucer are compressed and pressed for final pressing. .
