Description

TECHNICAL FIELD The present invention relates to a method for producing wet solid cosmetics.

Conventionally, multi-colored wet solid cosmetics are produced by filling a container with slurry-like cosmetics of multiple colors and pressing the cosmetics filled in the container to form a mold. Manufacturing methods are known.
For example, in the method for producing a multicolor wet cosmetic described in Patent Document 1, the inside of a cosmetic plate (container) is partitioned by a partition plate, and a plurality of colors of slurry is applied to each space partitioned by the partition plate. The wet solid cosmetics are manufactured by filling each of the cosmetics in the container, and subjecting the cosmetics filled in the container to a pressing process and stamping them.

However, in the method for producing a multicolor wet cosmetic described in Patent Document 1, although the color boundary of the multicolor wet cosmetic can be clarified, the shape corresponding to the pattern formed on the surface of the wet solid cosmetic can be obtained. partition plates must be prepared in advance, and there is a problem that it is not possible to flexibly cope with changes in pattern design. In addition, in the method for producing a multicolor wet cosmetic described in Patent Document 1, a pattern is formed on the surface of the multicolor wet cosmetic by partitioning the cosmetics of each color with a partition plate. There is a problem that it becomes a rough pattern.

An object of the present invention is to provide a method for producing a wet solid cosmetic that can flexibly respond to changes in pattern design and form a warm pattern.

In addition to the first production method, the following production method is disclosed as the method for producing the wet solid cosmetic of the present invention. That is, a method for producing a wet solid cosmetic by filling a container with a slurry cosmetic of a plurality of colors and subjecting the cosmetic filled in the container to a pressing process to form a wet solid cosmetic. First, a first cosmetic filling step of filling a part of the bottom surface of the container with the first cosmetic, and then filling the container with a different color cosmetic having a color different from that of the first cosmetic. , a different color cosmetic filling step of filling the entire bottom surface of the container with the cosmetic, and a stamping step of pressing and stamping the cosmetic filled in the container after that, and comparing with the different color cosmetic The slurry hardness of the first cosmetic having a smaller area ratio in the container is set to be higher than the slurry hardness of the unique cosmetic, and the first cosmetic is more difficult to remove than the unique cosmetic during use. (Second manufacturing method).

According to such a configuration, the wet solid cosmetic manufacturing method includes filling a portion of the bottom surface of the container with the first cosmetic, and then filling the container with a different color cosmetic having a color different from that of the first cosmetic. Accordingly, since the entire bottom surface of the container is filled with the cosmetic, the pattern of the wet solid cosmetic can be formed without partitioning the inside of the container with a partition plate. Therefore, the wet solid cosmetic manufacturing method of the present invention can flexibly respond to changes in pattern design, and can form warm patterns.
In addition, since the first cosmetic is a little more difficult to remove than the different-color cosmetic when used, when the first cosmetic and the different-color cosmetic are mixed and used, the color of the first cosmetic is expressed lightly. For this reason, for example, even if the unique cosmetic is filled so as to occupy a wider area than the first cosmetic, the user can take the unique cosmetic that is widely filled. Since it is easy to use, the wet solid cosmetic can be used without discomfort. In addition, even if the first cosmetic has a one-point pattern and the color tone difference is large compared to the different color cosmetics, the first cosmetic is expressed lighter, so the wet solid cosmetic still feels uncomfortable. can be used without

In the present invention , the first cosmetic refers to the first cosmetic to be filled among the slurry-like cosmetics to be filled in the container. , regardless of its shape, refers to a slurry-like cosmetic having a color different from that of the first cosmetic and to be filled after the first cosmetic is filled. Here, the different color cosmetics may be of one color or of multiple colors.

In the second manufacturing method of the present invention, the slurry hardness of the first cosmetic is higher than the slurry hardness of the unique cosmetic, and the cosmetic filled in the container is subjected to a pressing process in the stamping step. By doing so, the first cosmetic is preferably exposed on the surface of the wet solid cosmetic.

According to such a configuration, the first cosmetic is exposed on the surface of the wet solid cosmetic by subjecting the cosmetic filled in the container to a pressing process and stamping, so that the wet solid cosmetic is , a pattern can be formed from the front surface to the back surface of the wet solid cosmetic.

In addition, the first cosmetic having a high slurry hardness is a little more difficult to remove than the different-colored cosmetic during use. According to this, when the first cosmetic and the different color cosmetic are mixed and used, the color of the first cosmetic is expressed lightly. For this reason, for example, even if the first cosmetic is partially filled in a narrower area than the unique cosmetic, the user can easily remove the widely filled unique cosmetic. Therefore, wet solid cosmetics can be used without discomfort. In addition, even if the first cosmetic has a one-point pattern and the color tone difference is large compared to the different color cosmetics, the first cosmetic is expressed lighter, so the wet solid cosmetic still feels uncomfortable. can be used without In this way, the wet solid cosmetic can be adjusted in pattern and application color by variously combining the hue, area ratio, slurry hardness, etc. of the first cosmetic and the unique cosmetic. , the degree of freedom in design can be improved.

FIG. 2 shows a procedure for measuring the slurry hardness of cosmetics C11 and C12.
When measuring the slurry hardness of the cosmetics C11 and C12 with a viscometer (COMPAC-100II, manufactured by Sun Scientific Co., Ltd.), the operator, as shown in FIG. A 50 mL beaker) is filled with 50 mL of the first cosmetic C11 or the different color cosmetic C12. Then, as shown in FIG. 2B, the operator inserts the disk 11 along the axial direction into the first cosmetic C11 or the different-colored cosmetic C12 filled in the test container 10 (see FIG. 2B). medium arrow), and the slurry hardness (penetration hardness) of cosmetics C11 and C12 can be measured.
In addition, FIG. 2 is a diagram showing a state in which the slurry hardness of the first cosmetic C11 is measured with a viscometer.

In this manufacturing method, the ambient temperature was 25° C., the diameter of the disk 11 was 15 mm, the depth of insertion of the disk 11 from the surface of the first cosmetic C11 was 15 mm, and the insertion speed of the disk 11 was 400 mm/min. In this case, the slurry hardness (X1) of the first cosmetic C11 is set to 0.5N≦X1≦1.5N. The slurry hardness (Y1) of the unique cosmetic C12 is set to satisfy Y1≧ ^2.2X11.5 .

This wet solid cosmetic 1 is prepared by filling a cosmetic plate 2 with slurry-like cosmetics C11 and C12 of a plurality of colors having different slurry hardnesses, and pressing the cosmetics C11 and C12 filled in the cosmetic plate 2. It is produced by applying, stamping, and removing the volatile solvent in the cosmetics C11 and C12 by suction.
Hereinafter, the manufacturing method (first manufacturing method) of the wet solid cosmetic composition 1 will be described in order. In addition, in the manufacturing method of this wet solid cosmetic 1, all the steps may be performed by a manufacturing apparatus, or each step may be performed manually by an operator.

FIG. 3 is a diagram showing a state in which the cosmetic plate 2 is filled with the first cosmetic C11 according to the first manufacturing method.
In order to manufacture the wet solid cosmetic 1, first, as shown in FIG. This holder 3 is a hard member used to hold the cosmetic plate 2 in a series of work steps.
In addition, the height of the space 31 is higher than the height of the dressing plate 2. - 特許庁Also, the shape and size of the space 31 correspond to those of the dressing plate 2 . Here, in the state in which the cosmetic plate 2 is set in the space 31 , the upper surface 32 of the holder 3 exists at a position higher than the upper end 21 of the cosmetic plate 2 . This prevents the cosmetics C11 and C12 from overflowing the cosmetic tray 2 when the cosmetic tray 2 is filled with the cosmetics C11 and C12 in a later step.

Next, as shown in FIG. 3B, the filling device 4 fills the cosmetic tray 2 with the first cosmetic C11 through the filling nozzle 41 by discharging the first cosmetic C11 (first cosmetic C11). 1 cosmetics filling step).
Specifically, the filling device 4 moves the filling nozzle 41 (see the left-right direction arrow in FIG. 3B) and fills the entire bottom surface of the cosmetic plate 2 with the first cosmetic material C11 (see FIG. 3C). reference).

FIG. 4 is a diagram showing a state in which the cosmetic plate 2 is filled with the unique cosmetic C12 according to the first manufacturing method.
As shown in FIG. 4A, the filling device 4 fills the cosmetic tray 2 with the different color cosmetic C12 through the filling nozzle 42 by discharging the different color cosmetic C12 (different color cosmetic filling step). .
Specifically, the filling device 4 positions the filling nozzle 42 at the pattern forming portion of the cosmetic plate 2, and applies a different color cosmetic C12 having a color different from the first cosmetic C11 to a part of the cosmetic plate 2 in a predetermined pattern. (Refer to FIG. 1).
Note that the filling device 4 fills a part of the cosmetic plate 2 with the different color cosmetic C12 having a different color from the first cosmetic C11, and then vibrates the cosmetic plate 2 so as to fill the cosmetic plate 2 to the bottom. The different color cosmetic C12 may be removed.

FIG. 5 is a diagram showing a state in which the cosmetics C11 and C12 filled in the cosmetic plate 2 according to the first manufacturing method are being pressed.
After forming the pattern of the wet solid cosmetic 1 in the different-color cosmetic filling step, as shown in FIG. A holding body 3 is arranged. The press head 5 has a plurality of minute suction holes 51 formed to penetrate vertically in order to suck and remove the volatile solvent contained in the cosmetics C11 and C12. there is Also, the shape and size of the press surface (lower surface) of the press head 5 correspond to those of the opening of the space 31 of the holder 3 . Between the decorative plate 2 and the press head 5, an absorbent sheet 6 such as highly absorbent paper or non-woven fabric is interposed.

Then, as shown in FIG. 5B, the press device presses the cosmetics C11 and C12 filled in the cosmetic tray 2 by lowering the press head 5 (downward arrow in the figure). Strike a mold (stamping step). Here, as described above, the slurry hardness (X1) of the first cosmetic C11 is set to 0.5N≦X1≦1.5N, and the slurry hardness (Y1) of the unique cosmetic C12 is set to Y1≧2. It is set to be 2× ^{1 1.5} . According to this, the unique cosmetic C12 pushes away the first cosmetic C11 and reaches the bottom surface of the cosmetic plate 2, so that the wet solid cosmetic 1 is reliably spread from the front surface to the back surface of the wet solid cosmetic 1. Patterns can be formed. The volatile solvent contained in the cosmetics C11 and C12 is absorbed by the absorbent sheet 6 and sucked into a chamber (not shown) provided outside the press device through the suction hole 51 of the press head 5. removed.
Note that the volatile solvent contained in the cosmetics C11 and C12 may be absorbed only by the absorbent sheet 6 .

Next, as shown in FIG. 5(C), the press device raises the press head 5 (upward arrow in the figure) to end the press process.
Then, the wet solid cosmetic 1 can be manufactured by removing the cosmetic plate 2 set in the space 31 from the holder 3 after drying it under the drying conditions suitable for the volatile solvent.

The slurry hardness of the first cosmetic C11 is preferably set higher as the ratio of the area of the first cosmetic C11 to the bottom area of the cosmetic plate 2 is increased. According to this, it is possible to suppress excessive sinking of the different color cosmetic C12 into the first cosmetic C11 by applying the press treatment.

Table 3 below is a table showing the relationship between the slurry hardness of the cosmetics C11 and C12 according to the first manufacturing method and the pattern formed from the front surface to the back surface of the wet solid cosmetic 1. Specifically, in Table 3, the vertical direction is the slurry hardness of the first cosmetic C11 (0.5N, 0.7N, 0.9N, 1.2N, 1.5N), and the horizontal direction is the different color cosmetic C12. Table showing the relationship between the slurry hardness (0.6N, 0.7N, 1.1N, 1.7N, 2.5N, 4.0N) and the pattern formed from the surface to the back surface of the wet solid cosmetic 1 is. In Table 3, the depth of the dressing plate 2 is set to 3.5 mm, and the inner diameters of the filling nozzles 41 and 42 are set to 4.0 mm.

As shown in Table 3, the evaluation of the pattern formed from the front surface to the back surface of the wet solid cosmetic 1 was "○" when the different color cosmetic C12 reached the bottom surface of the cosmetic plate 2, and the bottom surface of the cosmetic plate 2. The case where the unique cosmetic material C12 did not reach the point is indicated as "x". A blank column in Table 3 indicates that the evaluation was not performed under that condition. This is because the higher the slurry hardness (Y1) of the unique cosmetic C12 is, the easier it is for the unique cosmetic C12 to reach the bottom surface of the cosmetic plate 2 .

FIG. 6 shows the slurry hardness and the slurry hardness of the first cosmetic C11 when a pattern is formed from the front surface to the back surface of the wet solid cosmetic 1 according to the first manufacturing method (when evaluated as “◯” in Table 3). , and the slurry hardness of the unique cosmetic C12. Specifically, the horizontal axis is the slurry hardness (X1) of the first cosmetic C11, and the vertical axis is the slurry hardness (Y1) of the unique cosmetic C12. 1 is a graph plotting the slurry hardness (Y1) of a unique cosmetic C12 (when evaluated as “◯” in Table 3) with ◇ marks.
In order to formulate the conditions under which the unique cosmetic C12 reaches the bottom surface of the cosmetic plate 2, an approximation formula for the relationship between the slurry hardnesses of the cosmetics C11 and C12 is obtained by exponential approximation. =1.9981X ^1.5669 (approximate formula 1).

Here, as described above, the higher the slurry hardness of the unique cosmetic C12, the easier it is for the unique cosmetic C12 to reach the bottom surface of the cosmetic plate 2. Therefore, the unique cosmetic C12 reaches the bottom surface of the cosmetic plate 2. The approximation formula 1 is adjusted so as to exceed the slurry hardness (Y1) of the unique cosmetic C12 in the case of (evaluated as “◯” in Table 3). Specifically, the multiplier of approximate expression 1 is truncated to the second decimal place and set to 1.5, and the coefficient of approximate expression 1 is adjusted so that Y=2.2X ^1.5 (approximate expression 2) got According to this, the slurry hardness (Y') of the cosmetic 2 calculated by the approximate expression 2 is, as plotted by the □ mark, when the different color cosmetic C12 reaches the bottom surface of the cosmetic plate 2 (Table 3 All of the slurry hardnesses (Y1) of the different color cosmetic C12 (when evaluated as "○" in ) are exceeded.
Therefore, in this manufacturing method, the slurry hardness (Y1) of the first cosmetic is set to Y≧2.2× ^1.5 , so that the slurry hardness (Y1) of the first cosmetic is set to Y≧2.2×1.5. By subjecting the cosmetics C11 and C12 to press processing and stamping, the unique cosmetic C12 reaches the bottom surface of the cosmetic plate 2 without fail.

According to this manufacturing method, the following functions and effects can be obtained.
(1) The manufacturing method (first manufacturing method) of the wet solid cosmetic 1 consists of filling the entire bottom surface of the cosmetic plate 2 with the first cosmetic C11, and then partially filling the cosmetic plate 2 with the first cosmetic C11. Since the different color cosmetic C12 is filled, the pattern of the wet solid cosmetic 1 can be formed without partitioning the inside of the cosmetic tray 2 with a partition plate. Therefore, the method for producing the wet solid cosmetic 1 can flexibly respond to changes in the design of the pattern, and can form a warm pattern.

(2) The slurry hardness of the unique cosmetic C12 is set to be different from the slurry hardness of the first cosmetic C11. The pattern and application color of the wet solid cosmetic 1 can be adjusted by variously combining the area ratio, slurry hardness, and the like, and the degree of freedom in design can be improved.
(3) The slurry hardness of the unique cosmetic C12 is higher than the slurry hardness of the first cosmetic C11. By doing so, the different color cosmetic C12 reaches the bottom surface of the cosmetic plate 2, so that the wet solid cosmetic 1 can form a pattern from the front surface to the back surface of the wet solid cosmetic 1.例文帳に追加

(4) The slurry hardness (X1) of the first cosmetic C11 is set to 0.5N≦X1≦1.5N, and the slurry hardness (Y1) of the unique cosmetic C12 is set to Y1≧2.2X1 ^1.5 . Therefore, the unique cosmetic C12 having a high slurry hardness is slightly more difficult to remove than the first cosmetic C11 during use. According to this, when the first cosmetic C11 and the unique cosmetic C12 are mixed and used, the color of the unique cosmetic C12 is expressed lightly. For this reason, for example, even if the first cosmetic C11 is filled so as to occupy a wider area than the different-colored cosmetic C12, the user does not want the first cosmetic C11 filled widely. The wet solid cosmetic composition 1 can be used without a sense of discomfort because it is easier to remove. In addition, even if the unique cosmetic C12 has a one-point pattern and the color tone difference is large compared to the first cosmetic C11, the unique cosmetic C12 is expressed lighter, so the wet solid cosmetic is also a wet solid cosmetic. 1 can be used without discomfort. In this way, the wet solid cosmetic 1 adjusts the pattern and application color of the wet solid cosmetic 1 by variously combining the hue, area ratio, slurry hardness, etc. of the first cosmetic C11 and the unique cosmetic C12. Therefore, the degree of freedom in design can be improved.

The present invention is not limited to this production method, and includes modifications, improvements, etc. within the scope of achieving the object of the present invention.
For example, in the present production method, the slurry hardness of the unique cosmetic C12 was set higher than the slurry hardness of the first cosmetic C11, but the slurry hardness of the unique cosmetic C12 was the slurry hardness of the first cosmetic C11. It does not have to be set higher than Specifically, the slurry hardness of the unique cosmetic C12 may be the same as the slurry hardness of the first cosmetic C11, or may be lower than the slurry hardness of the first cosmetic C11.

FIG. 7 is a diagram showing an example in which the slurry hardness of the unique cosmetic C12 according to the first manufacturing method is set to be the same as the slurry hardness of the first cosmetic C11. Specifically, FIG. 7 is a diagram showing a state in which the cosmetics C11 and C12 filled in the cosmetic tray 2 are being pressed.
After forming the pattern of the wet solid cosmetic 1 in the different color cosmetic filling step in the same manner as in the present manufacturing method, as shown in FIG. A cosmetic plate 2 and a holder 3 are arranged at the position.

Then, as shown in FIG. 7B, the press device presses the cosmetics C11 and C12 filled in the cosmetic tray 2 by lowering the press head 5 (downward arrow in the figure). Hit the mold.
Next, as shown in FIG. 7(C), the press device raises the press head 5 (upward arrow in the figure) to end the press process.

In this way, when the slurry hardness of the different color cosmetic C12 is set to be the same as the slurry hardness of the first cosmetic C11, the cosmetics C11 and C12 filled in the cosmetic plate 2 are subjected to a pressing process and stamped. Since the different color cosmetic C12 cannot sufficiently push aside the first cosmetic C11, the wet solid cosmetic 1 can form a pattern from the surface to the middle of the wet solid cosmetic 1.例文帳に追加

FIG. 8 is a diagram showing an example in which the slurry hardness of the unique cosmetic C12 according to the first manufacturing method is set lower than the slurry hardness of the first cosmetic C11. Specifically, FIG. 8 is a diagram showing a state in which the cosmetics C11 and C12 filled in the cosmetic tray 2 are being pressed.
After forming the pattern of the wet solid cosmetic 1 in the different color cosmetic filling step in the same manner as in the present manufacturing method, as shown in FIG. A cosmetic plate 2 and a holder 3 are arranged at the position.

Then, as shown in FIG. 8B, the press device presses the cosmetics C11 and C12 filled in the cosmetic tray 2 by lowering the press head 5 (downward arrow in the figure). Hit the mold.
Next, as shown in FIG. 8(C), the press device raises the press head 5 (upward arrow in the drawing) to complete the press process.

In this way, when the slurry hardness of the unique cosmetic C12 is set lower than the slurry hardness of the first cosmetic C11, the cosmetics C11 and C12 filled in the cosmetic plate 2 are subjected to a pressing process to form a die. When doing so, the different color cosmetic C12 cannot push aside the first cosmetic C11, so that the wet solid cosmetic 1 can form a pattern so as to spread over the surface of the wet solid cosmetic 1.例文帳に追加

(5) The manufacturing method (second manufacturing method) of the wet solid cosmetic 1A includes filling a part of the bottom surface of the cosmetic plate 2 with the first cosmetic C22, and then placing the first cosmetic C22 on the cosmetic plate 2. By filling the unique cosmetics C21 of different colors, the entire bottom surface of the cosmetic tray 2 is filled with the cosmetics C21 and C22. Patterns can be formed. Therefore, the method for producing the wet solid cosmetic composition 1A can flexibly respond to changes in the design of the pattern, and can form a warm pattern.

(6) The slurry hardness of the first cosmetic C22 is higher than the slurry hardness of the unique cosmetic C21. By doing so, the first cosmetic C22 is exposed on the surface of the wet solid cosmetic 1A, so that the wet solid cosmetic 1A can form a pattern from the surface to the back of the wet solid cosmetic 1A. Also, the first cosmetic C22 having a high slurry hardness is slightly more difficult to remove than the different color cosmetic C21 during use. According to this, when the first cosmetic C22 and the unique cosmetic C21 are mixed and used, the color of the first cosmetic C22 is expressed lightly. For this reason, for example, even if the first cosmetic C22 is partially filled with a narrower area than the unique cosmetic C21, the user prefers the widely filled unique cosmetic C21. The wet solid cosmetic composition 1A can be used without a sense of discomfort because it can be easily removed. In addition, even if the first cosmetic C22 has a one-point pattern and the color tone difference is large compared to the different-color cosmetic C21, the first cosmetic C22 is expressed lighter, so the wet solid makeup is still good. You can use 1A without any sense of incongruity. Thus, the wet solid cosmetic 1A adjusts the pattern and application color of the wet solid cosmetic 1A by variously combining the hue, area ratio, slurry hardness, etc. of the first cosmetic C22 and the unique cosmetic C21. Therefore, the degree of freedom in design can be improved.

The present invention is not limited to this production method, and includes modifications, improvements, etc. within the scope of achieving the object of the present invention.
For example, in the present production method, the first cosmetic C22 was exposed on the surface of the wet solid cosmetic 1A. It may be hidden inside the cosmetics C21. According to this, as the use of the wet solid cosmetic 1A is advanced, the first cosmetic C22 is gradually exposed to the outside, so that the user can enjoy using the wet solid cosmetic 1A. can continue.
