Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medium plate filling cosmetic and a method for filling a powder solid cosmetic into a medium plate.

[0002]

2. Description of the Related Art A large number of powdered cosmetics filled and solidified in a medium plate are provided. However, usually, in these products, the cosmetics are filled up to the upper edge of the side wall in a medium plate in which a side wall is erected on the outer periphery of the bottom plate. It is filled and the upper surface is flattened and solidified.

[0003]

By the way, such a flat-filled product has a low impact resistance, and the surface of the compact container may be cracked when dropped. Since it is flat, it is naturally lacking in three-dimensionality and a volumetric appearance cannot be expected.

[0004] It is an object of the present invention to provide a medium plate filling type cosmetic having a high impact resistance and an excellent filling appearance, and a method for producing the same.

[0005]

In order to solve the above problems, the present invention has the following means.

The cosmetic of the present invention is a medium-plate-filled cosmetic in which the powder solid cosmetic 10 is filled in a dome shape in a medium plate 12 in which a side wall 16 is erected on the outer periphery of a bottom plate 14.

Regarding the density of the powdered cosmetic material 10 filled, the dome surface layer is "dense" and the deep layer near the center of the lower plate is "rough".

Further, as another filling cosmetic material, the bottom plate 14 is used.
Provided is a medium-plate-filled cosmetic in which the powder solid cosmetic 10 is filled in a dome shape, leaving a space (S) in the center of the bottom plate in a medium plate 12 in which a side wall 16 is erected on the outer periphery of the medium.

In the above, it is preferable to provide a plurality of holes 18 in the central portion of the bottom plate of the inner plate 12.

The following are methods for filling the cosmetics of the present invention. The first method uses a receiving die 23 having a recess 22 for accommodating the inner plate 12, and a pressing die 24 that can enter the recess 22 of the receiving die 23. Here, the receiving mold 23 has a core mold 28 that forms the bottom of the recess 22 and moves up and down in the recess 22. A concave arc surface 30 having an arcuate cross section is provided on the pressing surface of the pressing die 24.

The inner plate 1 is placed in the receiving recess 22.
After containing 2, the powder cosmetic 10 is put in the recess 22,
The powdery cosmetic material 10 is solidified into a dome shape by allowing the powdery material 10 to enter the recess 22 and pressurizing the powdery cosmetic material 10 with the mold 24 and the core mold 28.

Also in the second method, the receiving die 23 having the recess 22 for accommodating the inner plate 12 and the pressing die 24 that can be inserted into the recess 22 of the receiving die 23 are used. Here, the receiving mold 23 has a core mold 28 that forms the bottom of the recess 22 and moves up and down in the recess 22, and has an arc-shaped cross section on the upper surface of the core mold 28 that forms the bottom of the recess 22. A concave arc surface 30 is provided.

In the present invention, basically, the cosmetic 10 is pressed by the concave arc surface 30 having an arcuate cross section, so that a so-called pressed powder causes a bridge phenomenon, and the density of the powder cosmetic 10 is a dome surface layer. It becomes "dense" and becomes "rough" in the deep dome.

[0018]

Embodiments of the present invention will be described below with reference to the drawings.

First, as shown in FIGS. 3 and 4, the inner plate 12 to be filled with the cosmetic material 10 has the side wall 1 on the outer periphery of the bottom plate 14.
A plurality of holes 18 are provided at the center of the bottom plate in a shape in which 6 is erected. Moreover, the convex portions 20 are radially formed around the plurality of groups of holes 18. Further, as shown in FIG. 5, the holes 18 are provided with a diameter of 1 mm and a pitch of 2 mm.

<Embodiment 1> First, the first filling method will be described with reference to FIG.
Will be explained. A mold for carrying out this filling method includes a receiving mold 23 having a recess 22 for accommodating the inner plate 12, and a receiving mold 23.
And a die 24 that can enter the recess 22. Further, the receiving mold 23 is cylindrical and has a frame mold 26 for forming an inner concave portion, and a bottom portion of the concave portion 22 and the concave portion 2
It is formed by a core mold 28 that moves up and down in the inside 2. A concave arc surface 30 having an arcuate cross section is provided on the pressing surface of the pressing die 24. The upper surface of the core mold 28 is flat.

First, the inner plate 12 is placed in the recess 22, the powder cosmetic 10 is further filled, the upper surface is scraped off to be flat, and then pressed by the pressing die 24 through the nylon or acetate cloth 32. .. At this time, the core die 28 is raised to move the pressing die 2
4 and the core mold 28 pressurize. As a result, the cosmetic material 10 is filled in a dome shape. The filled cosmetic material 10 is in a “dense” state in which the layer near the surface of the dome has a large density, and the deeper layer has a smaller density and becomes “rough”. Further, the peripheral edge is compressed into a flat plate shape, has a larger compression ratio than the dome portion, and is in a "dense" state. Therefore, the dome portion is supported and protected by the just circular frame.

Since the bottom plate 14 of the inner plate 12 is provided with a large number of holes 18, the cosmetic material 10 bites into the holes 18 and strengthens the bonding of the cosmetic material 10 to the inner plate 12.

The formulation of the cosmetic 10 used is as follows. Talc: 70.0 parts by weight Sericite: 5.0 parts by weight Hollow acrylic powder: 1.8 parts by weight Spherical Silica: 5.0 parts by weight Mica: 4.0 parts by weight 2-ethylhexanoic acid triglyceride 8.0 parts by weight Preservative: .. 0.2 parts by weight Fragrance .............. 2.0 parts by weight When the drop test of the obtained medium plate 12 filled cosmetic was conducted, it was compared with a conventional product having a flat surface, The frequency of cracks on the surface was low. As the test, as shown in FIG. 12, a test was performed in which the inner plate was erected and dropped from a height of 50 cm in a vertical state, and a test in which the inner plate was dropped from a height of 50 cm in a horizontal state as shown in FIG. 10 test products each
Individual pieces were prepared, and each was adhered in a compact container of the same type with a melt agent, and a drop test was conducted 10 times each. The hardness is JIS K-6301 (load 1
Pounds).

The results are shown in Table 1.

[0025]

[Table 1] If the surface is flat, the hardness is too hard and the usability is just a step away. Therefore, it was found that the hardness should be the same as that of the dome-shaped one, but if the hardness is made softer with the plate-like shape, cracks tend to occur.

<Embodiment 2> Next, the second filling method will be described with reference to FIG.
~ It demonstrates by FIG. A mold for carrying out this filling method includes a receiving mold 23 having a recess 22 for accommodating the inner plate 12,
It has a pressing die 24 that can enter into the recess 22 of the receiving die 23. Further, the receiving die 23 is formed by a frame die 26 that is cylindrical and forms an inner recess, and a core die 28 that forms the bottom of the recess 22 and moves up and down in the recess 22.

The pressing surface of the pressing die 24 is a flat surface and the core die 2
A concave arc surface 30 having an arcuate cross section is provided on the upper surface of 8. Further, a fitting groove 34 into which the side wall 16 of the inner tray 12 is fitted is formed at the upper end of the inner periphery of the frame die 26.

In molding, first, as shown in FIG. 8A, the powder cosmetic 10 is put in the recess 22 and then the powder cosmetic 10 is formed as shown in FIG. 8B.
As shown in FIG. 8A, the excess cosmetic material 10 is scraped off, and as shown in FIG. 8C, the inner plate 12 is fitted in the fitting groove 34 upside down.

The same operation can be performed as shown in FIGS. 9 (a) to 9 (c). However, in FIG. 9, the ring 36 fitted into the fitting groove 34 is used as a jig. That is, as shown in FIG. 9A, a ring 36 having the same inner diameter as that of the frame mold 26 is fitted into the fitting groove 34, and the recess 22 is filled with the powder cosmetic material 10. Then, as shown in FIG. 9 (b), extra cosmetics 1
9 is scraped off, and as shown in FIG. 9C, the inner tray 12 is fitted upside down in the fitting groove 34 after the ring 36 is removed.
The ring 36 is formed of iron, and is attracted by a magnet and pulled out.

After the above, as shown in FIG. 7, the core mold 28 is raised and the inner plate 12 is pressed from above by the pressing mold 24 to solidify the powder cosmetic material 10. When pressing with the pressing die 24, a cloth 32 of nylon or acetate and a metal or nylon thread 10 to 70 shoe 38 are inserted between the inner plate 12 and the pressing die 24.

In this example, the mold is the reverse of that of the first embodiment,
It has the following advantages: That is, in the first embodiment, the recess 22
It is supplied inside and the upper surface is scraped off flatly, and the flat upper surface is made into a dome shape by the concave arc surface 30 having an arcuate cross section of the pressing die 24. 10 may have variations in hardness.

On the other hand, in the second embodiment, the cosmetic material 10 is filled on the concave arc surface 30 having an arcuate cross section on the upper surface of the core, and is compressed and solidified as it is. Therefore, the strain applied to the cosmetic material 10 is small. Therefore, there is little variation in hardness.

The cosmetic 10 is filled in a dome shape, and in the filled cosmetic 10, the density of the layer close to the dome surface is "dense" and the density of the deep layer is "rough".
Is the same as. The formulation of the used cosmetic material 10 is also the same as in Example 1.

When the drop test of the obtained medium dish-filled cosmetic composition 10 was conducted, the frequency of cracks on the surface was less than that of the conventional product having a flat surface. The test method is Example 1
Is the same as

The results are shown in Table 2.

[0036]

[Table 2] <Embodiment 3> An embodiment of the third method will be described with reference to FIGS.

In this method, the pressing surface of the pressing die 24 is provided with a convex arc surface 40 having an arc-shaped cross section and protruding downward. Otherwise, the same apparatus as in Example 2 is used.

First, as shown in FIG. 10, the receiving type recess 22 is formed.
Put the powder cosmetic 10 inside and scrape off the upper surface. Next, the pressing die 24 having the convex arc surface 40 having an arcuate cross section on the lower surface is advanced into the recess 22 to press the powder cosmetic 10 together with the core die 28. At this time, the cloth 32 is interposed between the die 24 and the cosmetic 10.

As a result, as shown in FIG. 11, the cosmetic 10 having an arc-shaped cross section is formed, and therefore, the inner plate 12 is further formed.
Upside down and fit into the fitting groove 34, and the mesh 3
The middle plate 12 is pressed by a pressing die 24 having a flat lower surface via 8 and the core die 28 is raised. As a result, FIG.
As shown in, the powder solid cosmetic material 10 can be filled in the middle plate 12 in a dome shape, leaving a space (S) in the central portion of the bottom plate of the middle plate 12. The formulation of the used cosmetic 10 is the same as in Example 1.

The height of the space is preferably about 0.2 to 1.0 mm. When the drop test of the obtained middle dish-filled cosmetics was conducted, the frequency with which the surface was cracked was less than that of the conventional product having a flat surface.

The results are shown in Table 3.

[0042]

[Table 3] In Example 3, the hardness was stable, but since the molding press was performed twice, the adhesion to the inner plate was weaker than that of the molding press performed once.

[0043]

EFFECTS OF THE INVENTION According to the present invention, the powder cosmetic is solidified into a dome shape, so that a three-dimensional effect and a voluminous effect are exhibited and the appearance is good.

Further, since it has a dome structure, it is strong against impact force, and there is little problem that the filled cosmetic material is cracked when the contained compact container is dropped.

Furthermore, since the cosmetic material projects upward, it is easy to wipe off the cosmetic material and use it. In addition, when a large number of holes are provided in the center of the bottom plate of the inner plate, it is possible to prevent air from escaping from the inner plate during molding and cracking of the upper cosmetic surface. On the other hand, in the case where the bottom plate has no holes, air remains at the bottom, and after molding, it expands due to heat, which causes cracks on the upper surface of the cosmetic.
