  By the way, the decoration of oily solid cosmetics includes pearl agent spray, uneven patterns, and the like, but there is a disadvantage that it is difficult to transfer a beautiful pattern if a complicated pattern is to be applied. This is because oily solid cosmetics are characterized in that their surfaces are liable to collapse and are also sticky due to their oiliness.

  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 oil-based solid cosmetics simply and at low cost with good appearance.

  In order to solve this problem, the present invention provides a method for producing an oily solid cosmetic product. The manufacturing method includes a base, a first elastic part having a stamped surface engraved with unevenness, and a base and the first elastic part. The first elastic part and the oily solid cosmetic A step of preparing a stamp body having a softer second elastic portion, a step of attaching powder cosmetic to a convex portion that is a part of a stamp surface of the stamp body, and a powder cosmetic adhering to the convex portion And transferring the pattern onto the surface of the oily solid cosmetic by bringing the stamped surface into contact with the surface of the oily solid cosmetic.

  Here, in this invention, it is preferable that the 2nd elastic part is comprised by sponge, urethane, a spring, or a bellows. The color of the powder cosmetic is preferably different from the color of the oily solid cosmetic.

  According to the present invention, the surface of the oil-based solid cosmetic is provided with the first elastic portion and the second elastic portion softer than the oil-based solid cosmetic interposed between the base and the first elastic portion. Transfer the pattern to. Thereby, when the stamp body is pressed, an excessive force is absorbed by the second elastic portion. Therefore, it is possible to form a beautiful pattern easily and at low cost even for oily solid cosmetics that are liable to cause surface collapse and stickiness, and even a complicated pattern can be easily formed. . Moreover, a fresh taste can be given to the user who uses an oil-based solid cosmetic product, and it becomes possible to improve the product appeal power by the eye catch effect.

  FIG. 1 is a perspective view of an oily solid cosmetic product according to the present embodiment. This oil-based solid 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 lipstick, eye shadow, foundation, etc., but the exposed surface has an uneven pattern (that is, the surface is undulated). A pattern expressed by shading) is expressed.

  FIG. 2 is a cross-sectional view of the cosmetic 4 filled in the decorative dish 3. This cosmetic 4 has a laminated structure, and has a lower oily solid cosmetic 4a and an upper powder cosmetic 4b. The oily solid cosmetic 4a is obtained by solidifying an oily cosmetic such as lipstick, eye shadow, and foundation. However, the surface of the oily solid cosmetic 4a tends to collapse or become sticky due to the characteristic properties of the oil. The powder cosmetic 4b laminated on the oily solid cosmetic 4a contains components different from those of the oily solid cosmetic 4a. In this embodiment, pearl, lame, or the like is assumed. Both the oily solid cosmetic 4a and the powder cosmetic 4b are formed on the basis of a cosmetic powder. However, the powdered cosmetic 4b includes the oily solid cosmetic 4a because the characteristic manufacturing method described below is used. Such a compression is not applied. Therefore, the density (particle density) of the powder cosmetic 4b that has not been compressed is lower than that of the oily solid cosmetic 4a that has been compressed. In addition, the powder cosmetic 4b does not cover the entire surface of the oily solid cosmetic 4a whose surface is undulated, but is partially adhered, specifically, the powder cosmetic 4b is adhered. The concave portion and the convex portion to which the powder cosmetic 4b is not attached are present in a mixed state.

  In order to give the user a fresh taste and improve the eye catching effect, the oily solid cosmetic 4a and the powder cosmetic 4b are preferably colored in “different colors”. 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”.

  Hereinafter, the manufacturing method of the oily solid cosmetic product 1 described above will be described with reference to FIGS. 3 and 4. First, a stamp body 6 as shown in FIG. 3 is prepared. The stamp body 6 includes a base portion 6a, a first elastic portion 6b, and a second elastic portion 6d. For the base 6a, a member having relatively high rigidity, such as metal or plastic, which is not easily deformed is used. The first elastic portion 6b is formed of an elastic body such as silicone rubber or elastomer (synthetic rubber), for example, and has a stamp surface 6c below it. A pattern (for example, a flower pattern) to be transferred is engraved on the stamp surface 6c due to the unevenness of the surface. The second elastic part 6d interposed between the base part 6a and the first elastic part 6b is made of a softer material than the oily solid cosmetic 4a to be stamped. In the present embodiment, the second elastic part 6d is made of sponge. Is formed. In the present embodiment, as an example, a sponge that contracts by about 2 to 5 mm when a force of 2.4 N is applied is used. Here, as specifications required for the second elastic portion 6d, in addition to (1) being softer than the oily solid cosmetic 4a, (2) being softer than the first elastic portion 6b is also required. If the sandwiched second elastic portion 6d is harder than the material of the stamp surface 6c, the oil-based solid cosmetic material easily breaks down, making it difficult to perform good pattern transfer. As long as the required specifications are satisfied, the material of the second elastic portion 6d may be urethane, a spring, a bellows, or the like in addition to the sponge.

  Next, the powder cosmetic 4b is made to adhere substantially uniformly to the convex portion which is a part of the stamp surface 6c of the stamp body 6. The pearl or the like as the powder cosmetic 4b may be a single color, or a plurality of colors may be mixed.

  Next, oily cosmetic material 4a is prepared by filling the cosmetic dish 3 with oily cosmetic material and solidifying it. Then, as shown in FIG. 4 (a), the stamp surface 6c is brought into contact with the oily solid cosmetic 4a from above, and then the stamp surface 6c is contacted with the oily solid cosmetic 4a as shown in FIG. 4 (b). Separated from the surface of Thereby, according to the unevenness | corrugation of the stamp surface 6c, the powder cosmetics 4b adhere to the surface of the oil-based solid cosmetic 4a, and a pattern is transcribe | transferred. The strength with which the stamp body 6 is brought into contact with the surface of the oily solid cosmetic 4a, the press range, the material and hardness of the elastic body are appropriately set through prior experiments and simulations.

  As described above, according to this embodiment, the stamp body 6 having the sandwich structure in which the second elastic portion 6d is interposed between the base portion 6a and the first elastic portion 6b, the oil-based solid cosmetic 4a is used. Pattern transfer is performed. Thereby, when the stamp body 6 is pressed (when the stamp surface 6c comes into contact with the surface of the oily solid cosmetic material 4a), an excessive force is absorbed by the second elastic portion 6d. Therefore, it is possible to form a beautiful pattern easily and at low cost on the oily solid cosmetic 4a that is liable to cause surface collapse and stickiness, and it is possible to easily form even a complicated pattern. it can. Moreover, a fresh taste can be given to the user who uses oil-based solid cosmetic product 1, and it becomes possible to aim at the improvement of the product appeal by an eye catch effect.
