As another method, a method of forming an uneven pattern on the surface by partially peeling the surface of the solid cosmetic formed by compression molding with a laser or the like is also known.
JP-A-8-154732

  However, as in Patent Document 1, the method of transferring a pattern at the time of compression molding has a disadvantage that the more complicated the pattern is, the more difficult it is to transfer a beautiful pattern. This is because, firstly, wrinkles (gather) due to the unevenness of the pattern are likely to occur on the thin paper covering the surface of the powder cosmetic, which hinders pattern transfer. Second, the pattern transfer mold is elastically deformed by the compression die, which causes deformation of the transferred pattern. On the other hand, in the method of peeling the surface of the solid cosmetic with a laser or the like, not only is the apparatus itself such as a laser expensive, but it also takes a long time to form a pattern, which causes an increase in the cost of the cosmetic product. .

  This invention is made | formed in view of this situation, The objective is to perform the formation of the pattern with respect to the surface of a solid cosmetics simply and at low cost with good appearance.

  In order to solve such a problem, the first invention is a press surface of a pressing die formed of an elastic body, wherein the pressing surface on which a pattern is engraved by unevenness is brought into contact with a solid cosmetic, and the pressing die is Provided is a method for producing a cosmetic product in which a pattern is transferred onto the surface of a solid cosmetic by pressing the solid cosmetic.

  2nd invention is the press surface which the 1st step which laminates | stacks the thin film layer containing the component different from solid cosmetics on a solid cosmetic, and the stamp formed by the elastic body, Comprising: The pressed surface on which the pattern is engraved is brought into contact with the solid cosmetic material covered with the thin film layer, the pressing die is pressed onto the solid cosmetic material, and the thin film layer is partially peeled off, so that the surface of the solid cosmetic material is applied. There is provided a method for manufacturing a cosmetic product comprising a second step of transferring a pattern.

  Here, it is preferable that the 1st step in 2nd invention is a step which laminates | stacks a thin film layer by spraying the liquid mixture which mixed powder cosmetics in the solvent on the surface of solid cosmetics. The color of the thin film layer is preferably different from the color of the solid cosmetic.

  The third invention provides a cosmetic product having a solid cosmetic and a thin film layer formed on the surface of the solid cosmetic and containing a component different from the solid cosmetic. The thin film layer is present in a state where a portion covering the solid cosmetic and a portion where the solid cosmetic is exposed are mixed, thereby expressing a pattern on the surface of the solid cosmetic.

Here, in the third invention, the density of the thin film layer is preferably lower than the density of the solid cosmetic, and the color of the thin film layer may be different from the color of the solid cosmetic.

  According to the first or second invention, a beautiful pattern can be formed on the surface of a solid cosmetic material simply and at low cost, and even a complicated pattern can be easily formed. Can do. Further, according to the third invention, it is possible to give a fresh taste to the user who uses the cosmetic product, and it is possible to improve the product appealing power by the eye catching effect.

  FIG. 1 is a perspective view of a cosmetic product according to the present embodiment. The cosmetic product 1 is mainly composed of a cosmetic container 2, a cosmetic dish 3, and a cosmetic 4 filled in the cosmetic dish 3. The cosmetic container 2 is a transparent plastic container made of a polycarbonate resin, a polyethylene terephthalate resin, or the like, and a storage portion that is recessed in a concave shape is formed therein. In this storage portion, a cosmetic dish 3 made of metal such as aluminum, aluminum alloy, stainless steel, or synthetic resin such as polyethylene terephthalate resin is stored. Moreover, the cover part 2a which can be opened and closed is attached to the cosmetics container 2, and when this cover part 2a is opened, the upper part of the cosmetics container 2 will open and the cosmetics 4 will be exposed. This cosmetic 4 is obtained by solidifying a powdery cosmetic such as a foundation, a face color, an eye shadow, etc., but the exposed surface has an uneven pattern (that is, the surface is undulated). The pattern is expressed by shading).

  FIG. 2 is a cross-sectional view of the cosmetic 4 filled in the decorative dish 3. The cosmetic 4 has a laminated structure, and includes a lower solid cosmetic 4a and an upper thin film layer 4b. The solid cosmetic 4a is a cast product obtained by solidifying a powder cosmetic such as an eye shadow or a face color by compression molding. Further, the thin film layer 4b laminated on the solid cosmetic 4a contains components different from those of the solid cosmetic 4a. In this embodiment, powder cosmetics such as pearl and lame (what is the solid cosmetic 4a?) Different). It should be noted here that both the solid cosmetic 4a and the thin film layer 4b are formed on the basis of a powder cosmetic, but because the characteristic manufacturing method described later is used, the thin cosmetic layer 4b has a solid cosmetic. This is the point that the compression molding like 4a is not applied. Therefore, the density (particle density) of the thin film layer 4b not subjected to compression is lower than that of the solid cosmetic 4a subjected to compression. Furthermore, the thin film layer 4b does not cover the entire surface of the solid cosmetic 4a, but a portion covering the solid cosmetic 4a (convex portion) and a portion where the solid cosmetic 4b is exposed (concave portion) are mixed. Exists in a state. Due to the influence of the press using the pressing die 6 described later, the solid cosmetic 4a in the concave pressed by the pressing die 6 is depressed more than that of the convex not pressed. The pattern on the surface of the solid cosmetic 4a is expressed by the presence or absence of the thin film layer 4b and the shadow caused by the unevenness including the depression of the solid cosmetic 4a.

  In addition, it is preferable that the solid cosmetic 4a and the thin film layer 4b are colored in “different colors” in order to give the user (or customer) a fresh taste and improve the eye catching effect. In this specification, the term “different colors” is used in the sense that it is sufficient if the user or the like can visually recognize the difference in color. Therefore, not only differences in lightness, saturation and hue, but also the same color, the one with pearl added and the other are “different colors”. In this case, the pattern is expressed not only by shading due to unevenness but also by a combination of a plurality of colors, so that the user can be more clearly aware of the pattern.

  Hereinafter, the manufacturing method of the cosmetic product 1 described above will be described with reference to FIGS. 3 to 5. First, as shown in FIG. 3, a solid cosmetic 4 a that is compression-molded in a decorative dish 3, in other words, a molded mold product is prepared, and a thin film layer 4 b is formed on the exposed surface. Specifically, the sprayed liquid is sprayed onto the exposed surface using a sprayer 5 by mixing a mixture of pearl and the like in a solvent. This mixed solution is obtained by adding a predetermined amount of pearl or the like to a solvent such as IPA (iso-propyl alcohol), oil or water, and stirring it sufficiently. The pearl or the like to be mixed with the solvent may be a single color, or a plurality of colors may be mixed. In some cases, other components such as paste components such as PVP may be added to the mixed solution. In addition, the spray amount of the liquid mixture, the spray angle, the distance from the sprayer 5 to the solid cosmetic 4a, and the like are set as appropriate through prior experiments, simulations, and the like. The spray of the mixed liquid not only forms the thin film layer 4b having a predetermined thickness, but also intends to soften the surface of the solid cosmetic 4a.

  Next, as shown in FIG. 4, for example, a stamping die 6 formed of an elastic body such as silicone rubber or elastomer (synthetic rubber) is prepared. A pattern (for example, a flower pattern) to be transferred is engraved on the press surface 6a of the die 6 due to the unevenness of the surface. Then, as shown in FIG. 5 (a), the pressing surface 6a is brought into contact with the solid cosmetic 4a covered with the thin film layer 4b from above, and the pressing die 6 is solid-coated with a predetermined strength. Press to 4a. Then, as shown in FIG. 4B, the pressing die 6 is separated from the solid cosmetic 4a. Thereby, only in the site | part which contacted the convex part of the press surface 6a, the thin film layer 4b peels and the solid cosmetics 4a are exposed. In this way, the uneven pattern can be transferred to the surface of the solid cosmetic 4a by partially peeling the thin film layer 4b. It should be noted that the strength of pressing the pressing die 6, the press range, the material and hardness of the elastic body are appropriately set through prior experiments and simulations.

  This transfer process is preferably performed before the sprayed mixed liquid dries, in other words, while the surface of the solid cosmetic 4a is soft. Thereby, it is possible to transfer the concavo-convex pattern satisfactorily without the solid cosmetic material 4a being cracked or chipped by the press of the die 6. At the same time, the thin film layer 4b on the solid cosmetic 4a can be easily and easily peeled off.

  Thus, in the manufacturing method of the cosmetic product 1 according to the present embodiment, the pattern is transferred using the stamp 6 after the compression molding. This eliminates the need for thin paper required for simultaneous compression molding and pattern transfer, thereby avoiding inconveniences (wrinkle problems due to pattern irregularities) that occur when thin paper is used. In addition, the press for pattern transfer does not require as much force as in compression molding. For this reason, even if the elastic die 6 is used, the elastic deformation hardly occurs, so that the transferred pattern is not deformed. Furthermore, the pattern transfer by the pressing die 6 does not require a complicated and expensive manufacturing apparatus such as a laser, and the operation can be completed in a very short time. For the reasons described above, it is possible to transfer a pattern easily and at low cost as compared with the prior art, and it is possible to transfer a complex pattern with good appearance.

  Further, in the manufacturing method according to the present embodiment, if the thin film layer 4b is further laminated on the solid cosmetic 4a after the compression molding, and the pattern transfer using the stamp 6 is performed on the surface, the shadow as the pattern is sufficient. Can be secured. And since the cosmetics product 1 provided with such a deeply carved pattern can give a fresh taste to a user etc., it becomes possible to aim at the improvement of the product appeal power by an eye catch effect. In particular, if a pattern is expressed using a plurality of colors, this effect can be further improved.
