Abstract

<P>PROBLEM TO BE SOLVED: To suppress the color unevenness of a cosmetic surface caused by the trace of striking or filling. <P>SOLUTION: This method for preparing the solid cosmetic includes: striking the cosmetic 4 filled in a filling space including the inside of a cosmetic dish 3 for flattening the filled surface of the cosmetic 4; then pushing a sponge 6c to deform the flat-filled surface of the cosmetic 4 to erase the trace remaining on the filled surface after the striking; and then stamping the cosmetic 4 with no traces on the filled surface. <P>COPYRIGHT: (C)2011,JPO&amp;INPIT

Description

The present invention relates to a method for producing a solid cosmetic, and more particularly to measures against color unevenness on the surface of the cosmetic.
About.

  For example, Patent Document 1 discloses a production of a solid powder cosmetic in which a cosmetic filled in a filling space including the inside of a decorative dish is scraped off with a molding head, and the cosmetic whose surface is flattened by the scraping is cast. A method is disclosed.

JP 2009-102280 A

  By the way, in many cases, the surface of the cosmetic material that has been worn out by the molding head is left with traces of fine streaks or filling marks that are generated at portions corresponding to the filling holes of the cosmetic material. If the cosmetic is cast with such a mark remaining, it may become uneven in color and appear on the surface of the cosmetic, leading to a decrease in appearance.

  This invention is made | formed in view of this situation, The objective is to suppress the color nonuniformity of the cosmetics surface resulting from an abrasion mark and a filling trace.

  In order to solve this problem, the present invention includes a first step of flattening the filling surface of the cosmetic by rubbing the cosmetic filled in the filling space including the interior of the cosmetic dish, and flattening the cosmetic. A solid cosmetic comprising: a second step of deforming the filling surface to erase the traces remaining on the filling surface after scuffing; and a third step of casting the cosmetic from which the traces of the filling surface have been erased A manufacturing method is provided.

  Here, in the present invention, the second step is preferably a step of pressing a sponge against the cosmetic filling surface to deform the flat filling surface of the cosmetic into a curved surface.

  According to the present invention, the cosmetic filling is performed after the flat filling surface of the cosmetic is deformed and the traces remaining on the filling surface after scraping are erased. By casting the cosmetic material that has been subjected to such a surface treatment, the deformed filling surface collapses and a flat cosmetic surface is formed again. By performing the surface treatment of the cosmetic prior to the casting, the color unevenness on the cosmetic surface due to the scraping trace or the filling trace can be effectively suppressed.

  A method for producing a solid cosmetic according to the present embodiment will be described with reference to FIGS. Examples of solid cosmetics typically include foundations, face powders, eye shadows, etc., and may be either wet or dry cosmetics.

  FIG. 1 is an explanatory diagram of a scraping process. Below the filling space formed in the mold 1, a dressing plate 3 placed on the lifting platform 2 is arranged. The lifting platform 2 is moved up and down by a cylinder (not shown), and the attachment and detachment of the dressing plate 3 to and from the mold 2 is performed by this lifting and lowering. The filling space including the inside of the decorative tray 3 is filled with the cosmetic 4 by a hopper or an injection nozzle (not shown). The top of the filled cosmetic material 4 is scraped off by the molding head 5 that slides horizontally on the mold 1, thereby flattening the filling surface of the cosmetic material 4. In many cases, the filling surface of the cosmetic material 4 that has been worn out by the molding head 5 is left with traces of fine streaks or filling marks that are generated at portions corresponding to the filling holes of the cosmetic material.

  2 and 3 are explanatory views of the surface treatment process. The feature of this embodiment is that this step is added to the conventional work step. In this step, the flat filling surface of the cosmetic 4 is deformed, and the traces remaining on the filling surface after scraping are erased. Specifically, first, as shown in FIG. 2, the mold 1 that has undergone the previous scuffing process is set immediately below the surface treatment apparatus 6. The surface treatment apparatus 6 is mainly composed of a cylinder 6a, a drive arm 6b, and a sponge 6c. The sponge 6c is attached to the tip of the drive arm 6b that expands and contracts by the cylinder 6a, and can be displaced up and down. The sponge 6 c has a size larger than the opening shape of the mold 1 so that the entire filling surface of the cosmetic 4 can be covered. The sponge 6c is a flexible spongy fibrous member, and as its material, for example, cotton, NBR, NR, wet urethane (rubycell), dry urethane, silicon, film type, PVA, flocky type, etc. are used. Can do.

  Next, as shown in FIG. 3, the driven sponge 6 c is lowered by driving the cylinder 6 a, and the sponge 6 c is pressed against the filling surface of the cosmetic 4. The pressing pressure at that time is kept to a level sufficiently lower than the pressing pressure in the subsequent molding process so that the cosmetic 4 is not excessively pressed. Thereby, the flexible sponge 6c is elastically deformed, and due to this, the flat filling surface of the cosmetic 4 is deformed into a smooth curved surface. At that time, it is preferable not to cause a step between the upper surface of the mold 1 and the filling surface. The rubbing traces remaining on the filled surface after scraping and after filling are erased by deformation of the filled surface. Then, this process is complete | finished by raising the sponge 6c which was falling.

  FIG. 4 is an explanatory diagram of the die casting process. The cosmetic 4 from which the marks on the filling surface have been erased by the surface treatment process described above is pressed from above using the press head 7. By casting the cosmetic 4 in the filling space, the deformed filling surface collapses and a flat surface is formed again. By this casting process, the cosmetic 4 in the filling space is compressed to the upper edge of the decorative tray 3. And a series of processes are complete | finished by dropping the raising / lowering stand 2 which was raised, and taking out the dressing plate 3 from the metal mold | die 1. FIG.

  As described above, according to the present embodiment, the flat filling surface of the cosmetic 4 is deformed, and the mark remaining on the filled surface after scraping is erased, and then the cosmetic 4 is stamped. By this molding, the deformed filling surface is broken and a flat cosmetic surface is formed again. As described above, by performing the surface treatment of the cosmetic 4 prior to the casting, the color unevenness on the cosmetic surface due to the abrasion mark or the filling trace can be effectively suppressed. In particular, by using the flexible sponge 6c to deform the filling surface of the cosmetic material 4 into a curved surface shape, that is, a continuously curved surface shape, the color unevenness of the filling surface of the cosmetic material 4 can be more effectively suppressed.

  Further, according to the present embodiment, the air remaining in the cosmetic 4 can be effectively extracted by pressing the sponge 6c and pressurizing the interior of the cosmetic (air venting effect).

  As described above, the method for producing a solid cosmetic according to the present invention can be widely applied to both wet cosmetics and dry cosmetics.
