The solvent is sucked and removed from the powder cosmetic bulk slurry filled in each filling chamber 12.
Thereafter, by drying, a powder cosmetic in which the powder cosmetic bulk layer 11 is laminated on the inner surface 3 of the cosmetic filling portion 2 shown in FIGS. 23 and 24 can be obtained.

  FIG. 26 and FIG. 27 are powder cosmetics showing other examples of the shape of the powder cosmetic bulk layer laminated on the cosmetic filling portion, and the types are different in the state where there is no partition means in the cosmetic filling portion 2. A plurality of powder cosmetic bulk layers 11 are laminated.

In filling powder cosmetic bulk slurry in the powder cosmetic shown in FIGS. 26 and 27, as shown in FIG. 28, in the container 1, the bottom plate 8 in the cosmetic filling portion 2 is A plurality of filling holes 9 corresponding to a plurality of different types of powder cosmetic bulk layers 11 are formed, and a filling molded body 40 having a suction chamber 16 in the upper part and a vacuum pad 17 in the lower part is used.
The vacuum pad 17 is fitted to the opening of the cosmetic filling portion 2 to close the opening, and a pore 21 is formed to communicate the inside of the cosmetic filling portion 2 with the suction chamber 16.

  In filling the cosmetic powder filling portion 2 with the powder cosmetic slurry, first, the filling molded body 40 is lowered toward the opening of the cosmetic filling portion 2 and the vacuum pad 17 is moved to the cosmetic filling portion 2. The opening is closed by fitting into the two openings.

In this state, different types of powder cosmetic bulk slurry are pressure-filled into the cosmetic filling portion 2 from the respective filling holes 9 provided in the bottom plate 8 of the container 1, and the filled molded body 40 is sucked. The chambers 16 are decompressed, and the solvent is sucked and removed from the powder cosmetic bulk slurry filled in the respective filling chambers 12.
Thereafter, by drying, a powder cosmetic in which the powder cosmetic bulk layer 11 is laminated on the inner surface 3 of the cosmetic filling portion 2 shown in FIGS. 26 and 27 can be obtained.

  6 to 28, the adhesive layer 10 laminated on the inner surface 3 of the cosmetic filling portion 2 is omitted in any of the drawings.

  According to the packaged powder cosmetic thus configured, the adhesive layer 10 is laminated on the inner surface 3 of the cosmetic filling portion 2, and the powder cosmetic bulk layer 11 is laminated on the adhesive layer 10. Therefore, the powder cosmetic bulk layer 11 is bonded to the inner surface 3 of the cosmetic filling portion 2 in a state in which the powder cosmetic bulk layer 11 receives the swelling action of the adhesive and is familiar with the adhesive layer 10. 11 and the inner surface 3 of the cosmetic filling portion 2 are increased, and a stable fixed state is obtained between the powder cosmetic bulk layer 11 and the inner surface 3 of the cosmetic filling portion 2.

  In this example, the inner surface 3 of the cosmetic filling portion 2 is measured with a stylus type surface roughness measuring instrument defined in JIS B0651, and the centerline average roughness is 0 to 1000 μm in accordance with the method described in JIS B0601-1982. Since the surface area of the adhesive layer 10 laminated on the inner surface 3 of the cosmetic filling portion 2 is increased by the concave and convex portions 4 and 5 of the surface roughness, the powder cosmetic bulk layer 11 and The adhesive strength with the inner surface 3 of the cosmetic filling portion 2 is further increased, and the surface roughness convexity 5 on the inner surface 3 of the cosmetic filling portion 2 is bitten into the powder cosmetic bulk layer 11. The adhesive force between the powder cosmetic bulk layer 11 and the inner surface 3 of the cosmetic filling portion 2 is increased. The synergistic effect of the adhesive force by the adhesive layer 10 and the adhesive force by the surface roughness concave 4 and convex 5 on the inner surface 3 is between the powder cosmetic bulk layer 11 and the inner surface 3 of the cosmetic filling portion 2. A more stable fixed state can be obtained.

  Further, if the surface 4 has the concave 4 and the convex 5 on the inner surface 3 of the cosmetic filling portion 2, and the pattern 6 is formed on the inner surface 3 of the cosmetic filling portion 2 by the concave 4 and the convex 5. As the use of the powder cosmetic progresses and the powder cosmetic filled in the cosmetic filling portion 2 decreases and the powder cosmetic bulk layer 11 becomes thinner, the surface roughness of the powder cosmetic bulk layer 11 is increased. The convex 5 is raised and the pattern 6 is developed to exhibit a design effect.

  Further, if the information transmission means 7 such as characters, symbols, and numbers is formed on the inner surface 3 of the cosmetic filling portion 2 by the concave portions 4 and the convex portions 5, the use of powder cosmetics advances and the cosmetic filling portion 2 is filled. As the powdered cosmetic material is reduced and the powdered cosmetic bulk layer 11 becomes thinner, the surface roughness convexity 5 emerges on the surface of the powdered cosmetic bulk layer 11, and the powdered cosmetic bulk layer 11. The information transmitting means 7 such as characters, symbols, numbers, etc. appears on the surface and can transmit information to the user.

  In this example, the surface roughness of the inner surface 3 of the cosmetic filling portion 2 is 150 μm. However, the present invention is not limited to this, and the bottom surface serving as the inner surface 3 is flat (surface roughness) as shown in FIG. May be 0 μm).
