Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to solidification of a powder cosmetic capable of rapidly solidifying a powdery cosmetic base slurried with a solvent in a molding frame. A method and an apparatus thereof.

[Conventional technology]

Conventionally, for example, as a method of filling powdery cosmetics such as white powder and foundation in the middle plate of a compact case, a pressing method of filling the powdery cosmetic base into the middle plate and pressing,
A pouring method is known in which a powdery cosmetic base which is made into a slurry using a solvent is poured into an inner plate and the solvent is volatilized to solidify. However, in the pressing method, the powder cosmetic base easily scatters, so that not only the cosmetic base loses a lot but also the work environment is deteriorated, and the inner plate may be deformed by the pressing force at the time of pressing. is there. Also,
The pouring method has the drawback that the surface of the cosmetic material solidified by volatilization of the solvent causes depressions or cracks, or the solidified cosmetic material contracts and falls off from the inner plate.

Therefore, as shown in JP-B-57-60004 and JP-B-61-54766, cosmetics dissolved in a solvent to make them viscous are passed through a filling hole from the bottom of a saucer or a middle tray (hereinafter referred to as a saucer, etc.). By pressure injection filling into a saucer or the like, and using an absorbent body that absorbs the solvent in the absorbent body and solidifies the cosmetic material, or as shown in JP-A-61-17507, The bottomless container placed is filled with a slurry-like powder dispersion from the bottom side, and the solvent contained in the powder dispersion is discharged or dried to fix the powder in a mesh and solidify in the bottomless container. A method of using such a bottomless container has been proposed.

[Problems to be solved by the invention]

Thus, in the method of using the above-described absorber, since the absorber having a water-absorbing capillary action is used to remove the solvent from the viscous cosmetic material filled in the saucer or the like, it takes time to suck the solvent. The disadvantage is that the solvent is not absorbed at the filling port side, that is, the bottom side of the saucer, because only the portion of the cosmetic material filled in the saucer that comes into contact with the absorber solidifies early, and it takes time to dry. Not only does it cause unevenness, but also uneven coloring and uneven mixing of components are possible. Moreover, this method volatilizes the solvent in the saucer and solidifies it as a cosmetic, and is used directly as a product, so not only the product strength is weak, but also the residual amount of the solvent remaining on the bottom is slightly different. Therefore, there is a drawback that the product strength varies.

On the other hand, in the method using the bottomless container, the cosmetics cannot be used up because the powder is fixed to the mesh, and the solvent is wasted by pressing the surface of the powder dispersion liquid. Because it only discharges positively,
If the amount of the solvent is increased to improve the fluidity of the powder dispersion so that it can be filled in every corner of the container, it takes time to solidify the powder cosmetic, resulting in uneven or uneven coloring of the ingredients. It is possible and has the drawback of being inferior in productivity.

The present invention has been made in view of the above-mentioned drawbacks of the conventional technique, and the time required for solidifying the powder cosmetic can be shortened to 1/2 to 1/3 as compared with the conventional technique, resulting in excellent productivity. In addition, it is possible to uniformly fill the slurry-like material in the molding frame, and by uniformly sucking the solvent, it is possible to solidify the powder cosmetic into a homogeneous state without unevenness of components and color unevenness. An object of the present invention is to provide a method for solidifying a material and an apparatus therefor.

Next, an embodiment method of the present invention will be described using the above-mentioned apparatus.

First, a slurry-like material a for molding a solid eye shadow A which is a solid powder cosmetic as shown in FIG. 4 is produced. The composition of this slurry-like material a is as follows.

Pigment 23.0 parts by weight Mica 23.3 Mica titanium (pearl agent) 45.0 Zinc stearate 3.7 Liquid paraffin 5.0 Crystalline cellulose 1.0 Ethyl cellulose 0.6 Dimethyldihydrogenated tallow ammonium hectorite 1.0 Fragrance 0.3 Trichlorotrifluoroethane 100.0 (1 time amount) For each of the above components Of the slurry a
Is generated and filled in the liquid storage tank provided in the filling means 18.

On the other hand, insert the molding frame 1 into the molding frame fitting hole 5B of the base 5,
The end surface on the side of the opening 2 is brought into contact with the one-side hollow holding body 8 previously fitted to the base 5 via the nylon mesh 16, and then the pushing means 15 is operated to operate the other-side hollow holding body. The molding frame 1 is clamped between the left and right hollow clamping bodies 8 and 14 by pushing 14 in the direction of arrow B and pressing the other end of the molding frame 1 through the nylon mesh 16 on the other side. To do. At this time, the solvent suction port 10 'of the hollow holding member 14 on the other side and the solvent discharge port 7 of the base 5 are in communication with each other.

Then, the filling nozzle 18C is lowered in the direction of the arrow E and inserted into the filling port 1A of the molding frame 1, and the pressurizing pump 18A is driven to move the slurry-like material a in the liquid storage tank into the molding frame 1. And press fill. At the time of this filling, the slurry-like material a is completely pressure-filled at one time into the cosmetic molding portion 4 of the molding frame 1, so that the composition can be rapidly and quantitatively filled in a uniform state.

When the filling of the slurry-like material a is completed as described above, the stop valve 18D of the filling means 18 is closed and then the vacuum pump 19 is started. Then, the solvent in the slurry-like material a is about 400 to about 400 through each side opening 2, 3 of the molding frame 1 through each nylon mesh 16.
Each hollow sandwich in vaporized or liquid droplet state with 600 mm / Hg suction force
8,14, and the solvent suction port 10,10 'to the solvent discharge port 6,
7. Collect in an external solvent recovery tank or the like via each of the pipes 19A and 19B. The time required for sucking the solvent varies depending on the amount of the solvent mixed, but since the solvent is sucked through the openings 2 and 3 on both sides of the molding frame 1 at the same time, it is extremely short as compared with the conventional technique.
It takes about 3 seconds. Moreover, the solvent is used in each opening 2, 3 of the molding frame 1.
Since the solvent is sucked in and discharged from the entire surface, it is possible to prevent the solvent from partially remaining, resulting in uneven color and uneven component mixing.

After the solvent-removed solid eye shadow A is molded in the cosmetic molding portion 4 of the molding frame 1 as described above, the pushing means 15 is actuated to move the hollow holding body 14 on the other side in the arrow C direction. And the molding frame 1 is removed from the base 5. And the opening of the molding frame 1
The cosmetic of the solid eyeshadow A is completed by gently pushing the upper side of the solid eyeshadow A from 2, (3) and transferring it into the container G as shown in FIG. Further, after being taken out from the molding frame 1, it may be cut into a desired shape and size and accommodated in a saucer or the like. When the product is housed in a tray or the like, pressure is applied to push it in or punch it to obtain the final product, which makes it possible to make the product strength uniform and prevent cracks or the like from occurring.

In the examples, the total amount of the eye shadow base and the compounding ratio of the solvent trichlorotrifluoroethane were set to 1: 1. However, the solvent mixing ratio of the slurry-like substance used in the method of the present invention was 1% of the total amount of the base. Is 0.5 to 2.0, and particularly preferably 0.7 to 1.5.

According to the above-described embodiment method, the solvent is sucked and discharged after the slurry a is quantitatively filled in the molding frame 1. Therefore, the solid eye shadow A which is finely porous and good for a brush or the like is used.
Can be molded.

In addition, according to the embodiment, the slurry-like substance a is filled under pressure in the molding frame 1. Therefore, in the case of a low boiling point solvent, the slurry-like substance a is heated to near its boiling point to vaporize the solvent. By discharging the solid eyeshadow, bubbles can be prevented from being generated. Moreover, as described above, since it is possible to heat the slurry-like substance a under pressure filling, it is possible to use a water-containing solvent such as water-ethanol system, water-acetone system, or water-isopropyl alcohol system. A solvent suitable for the powder cosmetic base can be selected and used.

Although the embodiment has been described as the case where the filling means 18 is used to fill the slurry-like material a into the molding frame 1 under pressure, the solvent suction means 19 may be used to fill under reduced pressure. Further, pressure filling and pressure reduction filling may be performed simultaneously, and when the slurry-like material a is filled in the molding frame 1, the stop valve 18D of the filling means 18 may be closed and the solvent may be sucked by the solvent suction means 19. By doing so, there is an advantage that the filling time can be further shortened and the slurry-like material a can be completely filled even in every corner of the molding frame having a fine shape.

Further, the filling port 1A of the molding frame 1 in the apparatus of the embodiment is not limited to one, but a plurality of filling ports 1A may be formed, and the filling nozzles 18C of the filling means 18 may be provided as many as the filling ports. Further, instead of the cylindrical molding frame 1 of the embodiment, as shown in FIG.
A rectangular molding frame 1'having a rectangular cosmetic molding portion 4'may be used, or molding frames of various other shapes may be used. Further, although the nylon mesh 16 is taken as an example of the permeable membrane material in the embodiment, a filter paper, a mesh cloth or the like may be used.

〔The invention's effect〕

As described above in detail, according to the present invention, a molding frame whose both sides are opened is used, both openings of the molding frame are closed by a permeable membrane material, and each opening is held by a hollow holding member, Fill the inside with a cosmetic base slurried with a solvent,
Since the solvent is sucked simultaneously from both openings of the molding frame through each hollow sandwiching body, the solvent can be absorbed uniformly in an extremely short time, and the solvent partially remains to cause uneven coloring and blending of components. It is possible to prevent unevenness, form a homogeneous solid powder cosmetic in which each component is uniformly dispersed, and improve productivity as compared with the prior art. Moreover, after being solidified uniformly in the molding frame, it is taken out from the molding frame, and if necessary, it can be left as it is, or can be appropriately cut and pushed into the container, stamped, and made into the final product. The strength can be made uniform and cracks and the like can be prevented.
