Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel method for filling and molding solid cosmetics, and includes solid cosmetics such as solid foundation, solid white powder, solid eye shadow, solid blusher, solid lipstick, solid perfume, etc. It can be molded in multiple colors and does not lose its shape.

In addition, in the case of multiple colors, the boundaries between individual colors are clear.

The object of the present invention is to provide a method for filling and molding a novel solid cosmetic that has excellent impact resistance and ease of use.

Conventionally, the filling and molding method for cake-type solid cosmetics has been to use a cosmetic composition containing 10 to 20% by weight of oil and 90 to 80% by weight of powder. This is done by inserting the plate into a mold and compressing it from the top with a compressor at a pressure of 10 to 5 Q KPS.Also, if the oil content is 50% by weight or more, the oil content is large. By heating and melting the cosmetic composition, the fluidity becomes good, so it is poured directly into a medium plate or container, and then cooled and solidified. 1. In order to make the surface beautiful, etc., a low pressure of K 10 K61/l, 4 or less is applied. This is done using a method of compression. However, cosmetic compositions containing an intermediate amount of oil have extremely poor fluidity even when heated and melted, making it difficult to pour and fill them into an inner dish or container. Ta. A particularly proposed method involves injecting a cosmetic composition into a medium plate or container, which has become fluid to a certain extent by heating, and then compression-molding the composition by heating it above the temperature at which the solid oil contained therein solidifies. Alternatively, the cosmetic composition is melted by heating and pressurized into a cylindrical container, then cooled and solidified, and the solidified cosmetic is taken out from the cylindrical container and cut to an appropriate thickness to form a plate. The method used was to fill the inner tray, container, etc. and then compression mold it, but in either method, the cosmetics and the inner tray were filled.

There may be gaps or cracks between the container, etc.
In addition, it was not possible to obtain a satisfactory product due to the occurrence of cracks around the upper part of the inner plate, container, etc. However, as a result of various experimental studies, the present inventor has obtained a solid cosmetic that does not have such defects. The present invention was completed.

In the present invention, a solid cosmetic composition having heat-melting properties is filled through a filling hole in the guide plate from a filling nozzle into a through hole in a cut plate that slides closely between the guide plate and the holding plate, The cut plate is slid and the filling hole is closed by the cut plate, and the solid cosmetic composition is transferred to the compression molding section, and the solid cosmetic composition is placed in an inner tray that is removably engaged with the compression molding section. The solid cosmetic composition in the inner tray is then heated and melted, then cooled and solidified, or guided through a filling nozzle into the inner tray that is removably engaged with the through hole of the cut plate. A heat-melting solid cosmetic composition is filled through the filling hole of the plate, and the cut plate is slid to close the filling hole, and the inner plate is transferred to the compression molding section, and the inner plate is filled with the solid cosmetic composition. This is a filling molding method for solid cosmetics in which a solid cosmetic composition is compression molded, the solid cosmetic composition in an inner tray is first heated and melted, and then cooled and solidified.
