JPH0624940A - Production of powder cosmetic changed in color tone - Google Patents

Abstract

PURPOSE:To simply obtain a powder cosmetic having two different colors at both the side ends of a single container and changed in the color tones in a gradational state having no border between the color tones. CONSTITUTION:The method for producing the powder cosmetic changed in the color tones comprises mounting a dividing plate (3) on the diagonal cross section of a female mold (1), mounting the female mold in a cosmetic-receiving section (2), charging two powder cosmetics (5),(6) having different colors, respectively, so as to position at both the side ends of the container, removing the dividing plate (3), inserting a dividing frame (4) having plural dividing plates arranged in parallel to or at a constant angle to the side surface of the female mold (1) instead of the removed dividing plate (3), homogeneously mixing the powder cosmetics in each division, removing the dividing frame (4), and subsequently compressing the mixed cosmetics with a male mold. The cosmetic regularly changed in the color tones can simply be obtained only by preparing the two colored powder cosmetics to be positioned at both the side ends of the container.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a powder cosmetic in which two different colors are provided at both ends in a single container and there is no boundary in each color tone, that is, the color tone changes gradually.
The present invention relates to a simple manufacturing method.

[0002]

2. Description of the Related Art A method of manufacturing a powder cosmetic in which a color tone changes in a gradation in a single container is described in a case where a meshed hopper is divided into a plurality of spaces and each space has a different color tone. In which the cosmetics are stored and dropped into the inner plate while vibrating the hopper and filled, and the adjacent cosmetics are mixed with each other by vibration to gradually change the color tone (JP-A-61-97208). ) Or, set the inner plate with the top and one side open with the open side up and set it in the mold, and fill the powder cosmetics with different color tones in layers one by one, then add vibration to adjoin them. A material in which the boundary portions of cosmetics are mixed and compressed and solidified (Japanese Patent Laid-Open No. 194721/1989).
No.) is known.

[0003]

However, in any of the above-mentioned manufacturing methods, in order to obtain a natural color tone change, in addition to the two colors arranged at both ends of the container, some of these mixed colors before filling. Had to prepare for.

Further, according to the former manufacturing method, it is not possible to obtain a uniform change in color tone due to the scattering of powder, and it is difficult to uniformly fill the entire container. In this case, since the powder is not sufficiently filled in the gaps, the pressed cosmetics have a hardness difference between the gaps and the center, and there is a problem that the strength against drop is weak.

On the other hand, the latter manufacturing method involves layered filling of powder cosmetics of a plurality of colors, the process is complicated, and mass production is difficult.

The present invention solves the above problems and enables the production of powder cosmetics whose color tone changes uniformly and beautifully in a gradational manner simply by filling two colors located at both ends of the container. It is a thing.

[0007]

In the present invention, first, a partition plate is attached to a diagonal cross section of a female molding die, and the partition plate is attached to a cosmetic storage part such as a container or a gold plate, and each partition plate is divided. The compartments are filled with the two colors located at both ends of the container, then the partition plate is removed, and instead, several partitions are arranged parallel to the side of the molding female die or at a certain angle. A partition frame with a plate is fitted from the upper surface of the molding female mold, and vibration is applied so that the powder cosmetics in each compartment formed parallel to the side surface of the molding female mold or at a constant angle are uniform. And mixed to obtain a uniform gradation-like change in the color tone of the powder cosmetic.

[0008]

Therefore, the method for producing a powdery cosmetic having a changeable color tone according to the present invention comprises the following steps.

In the first step, one partition plate (3) is attached to the diagonal cross section of the molding female die (1), and the partition plate (3) is attached to the cosmetics storage section (2) such as a container or a gold plate. After filling the two-color powder cosmetics (5) and (6) located at both ends of the container into each compartment divided by the partition plate (3), the partition plate (3) is removed. By this step, the filled state of the cosmetic as shown in FIG. 4 is obtained.

In the second step, first, the molding female die (1) is used.
A partition frame (4) having a plurality of partition plates arranged parallel to the side surface of, or arranged at a constant angle is fitted from the upper surface of the female molding die (1). Then, the cosmetic material filled in the cosmetic material storage section (2) is divided as shown in FIG. 7. As is apparent from FIG. 7, the ratio of the filling amounts of the cosmetics (5) and (6) having different colors is the same as that of the cosmetics accommodating portion (2).
Gradually changes from one end to the other end.
Next, the cosmetics (5) and (6) in each section are mixed and homogenized by applying vibration or the like. As a result, the color tone of the cosmetic in each section gradually changes from one end to the other end of the cosmetic container according to the ratio of the filling amounts of the cosmetics (5) and (6).

Next, as a third step, the partition frame (4) is removed, and if necessary, a surface of the cosmetic material is covered with a tasser and compressed by a molding male mold (7) to mold.

[0012]

EXAMPLES The present invention will be described in more detail with reference to the following examples.

First, as shown in FIGS. 2 and 3, a molding female mold (1) having a partition plate (3) mounted on a diagonal section is mounted on a gold plate (2). In FIG. 3, two triangular prism-shaped voids formed by a partition plate (3) are filled with a powder cosmetic (5) and a powder cosmetic (6) having a color different from that of the powder cosmetic. Next, when the partition plate (3) is removed, the powdered cosmetic material is filled as shown in FIG.

Next, as shown in FIGS. 1 and 5, a partition frame (4) having several partition plates parallel to the side surfaces a, a'of the molding female die (1) is attached to the molding female die (1). Inset from above. At this time, as shown in FIG. 6, the powder cosmetics (5) and (6) filled in the molding die (1) are divided into several sections by the partition plate of the partition frame (4). When viewed from the upper surface of the molding die (1), as shown in FIG. 7, in each of the above-mentioned compartments, the powder cosmetic (5) and the powder cosmetic (5) and the powder cosmetic are provided from one end to the other end of the gold plate (2). (6) exists by changing the ratio of the filling amounts. Therefore, add vibration in this state,
The powder cosmetics (5) and (6) in each section are mixed and homogenized. As a result, the color tone of the powder cosmetics in each section of FIG.
The gold plate (2) gradually changes in a gradation shape from one end to the other end.

Finally, the partition frame (4) is removed, and it is compressed by a male molding die (7) and molded as shown in FIG.
A powdery cosmetic having a change in color tone is obtained.

[0016]

EFFECTS OF THE INVENTION According to the present invention, by simply preparing and filling the powder cosmetics of two colors located at both ends of the container, the color tone can be easily changed to gradation without the need for complicated manufacturing equipment and manufacturing process. It is possible to produce powder cosmetics that change.

Further, according to the manufacturing method of the present invention, there is no problem that the color tone is disturbed due to the scattering of the powder, the non-uniformity of the hardness of the product due to the non-uniform filling, and the drop strength are reduced. It is possible to provide a powder cosmetic in which the color tone changes in a gradation form from one end to the other end of the container.
