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 Japanese Patent Publication No. 57-60004 and Japanese Patent Publication No. 61-54766, cosmetics dissolved in a solvent to make them viscous are passed through a filling hole from the bottom of a saucer or an intermediate 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 prior art. As a result, the time required for solidification of powder cosmetics can be shortened to 1/2 to 1/3 as compared with the prior art. It is possible to prevent uneven composition and color unevenness of the components flowing out together with the solvent, and to mold a solid powder cosmetic with a complicated shape using a fluid slurry that has a high solvent mixing ratio. An object of the present invention is to provide a solidification method for powdery cosmetics and a device 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 blusher 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 20.0 (parts by weight) Mica 23.3 Mica titanium (pearl) 45.0 Zinc stearate 3.7 Lanolin 3.0 Olive oil 2.0 Crystalline cellulose 1.0 Ethylcellulose 0.6 Dimethyldihydrogenated tallow ammonium hectorite 1.0 Fragrance 0.3 Water-ethanol system (3: 7) Solvent 100.0 (1 time amount) ) A solvent is added to each of the above components to form a slurry-like substance a, which is filled in a liquid storage tank provided in the filling means 25 in advance.

On the other hand, insert the molding frame 1 into the molding frame fitting hole 5B of the base 5,
The end face on the side of the opening 2 is brought into contact with the one side holding body 8 previously fitted to the base 5 via the nylon mesh 22, and then the pushing means 21 is operated to operate the hollow holding body 15 on the other side. Is pressed in the direction of arrow B and pressed against the end face of the molding frame 1 on the side of the opening 3 through the nylon mesh 23 on the other side to clamp the molding frame 1 between the left and right clamping bodies 8 and 15. To do. At this time, the solvent suction port 17 of the hollow holding member 15 on the other side and the solvent discharge port 6 of the base 5 are in communication with each other.

After that, the filling nozzle 25C is lowered in the direction of arrow E to be fitted into the filling port 1A of the molding frame 1, and the pressurizing pump 25A 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 cosmetic material molding portion 4 of the molding frame 1 is completely filled with the slurry-like material a at once, 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 25D of the filling means 25 is closed, and then the heating element 26 is energized to generate heat and the vacuum pump 27 is started. As a result, the solvent in the slurry-like material a is sucked into the hollow holding body 15 with a suction force of about 400 to 600 mm / Hg, and at the same time, the heated air heated by the heating element 26 becomes warm air and is discharged on one side. The solvent in the slurry a is vaporized by being sucked into the molding frame 1 through the nylon mesh 22. Thus, the solvent in the slurry-like substance a is sucked into the hollow holding body 15 in a vaporized and droplet state, and is sequentially collected from the solvent suction port 17 through the solvent discharge port 6 to an external solvent recovery tank or the like.

The time required for sucking the solvent varies depending on the amount of the solvent blended, but since the heated air flows from the one side opening 2 of the molding frame 1 to the other side opening 3, it is extremely short as compared with the prior art, and Since the solvent can be completely vaporized and discharged by the heated air flowing through the slurry-like material a by the suction force of the solvent suction means 27, the solvent partially remains and the color is uneven.
It is possible to prevent uneven composition of the components and to omit a drying step as a separate step.

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 blusher base and the mixing ratio of the water-ethanol (3: 7) solvent were set to 1: 1. However, the solvent of the slurry-like substance a filled in the molding frame 1 was vaporized by heated air. Therefore, it is possible to use a slurry having a high fluidity by increasing the blending amount of the solvent.

According to the embodiment method described above, the solvent is discharged after the slurry a is filled in the molding frame 1 in a fixed amount, so that a solid blusher A having a fine porosity and a good puff can be molded. Further, according to the embodiment method in which the slurry-like material a is pressure-filled and the heated air is used, it is possible to heat and fill the slurry-like material a. A solvent containing water such as ethanol type or water-isopropyl alcohol type can be used, and a solvent compatible with the powder cosmetic base can be selected and used.

In the embodiment, the filling means 25 is used to pressurize and fill the slurry-like material a into the molding frame 1, but the solvent suction means 27 may be used to perform vacuum filling. Further, pressure filling and pressure reduction filling are performed at the same time, and when the molding material 1 is filled with the slurry-like material a, the stop valve 25D of the filling means 25 is closed to supply the heated air from the heating element 26 and the solvent suction means 27. The solvent may be sucked by means of this, and by doing so, the slurry-like material a can be completely filled and solidified even in every corner of the molding frame having a fine shape in a short time.

Further, although one filling port 1A of the molding frame 1 in the embodiment is provided, a plurality of filling ports 1A are provided and a filling nozzle 25C of the filling means 25 is provided.
Also, a configuration may be provided corresponding to the number of filling ports 1A. Further, instead of the cylindrical molding frame 1, as shown in FIG.

The device is characterized in that a disk-shaped shutter 31 is provided which can integrally open and close each vent hole 10 by rotating the one side holding body 8 of the first embodiment device. A pipe 32 having a stop valve 32A is connected between 8 and the solvent suction means 27. In order to fill and solidify the slurry-like material a in the molding frame 1 by the apparatus of this embodiment, the shutter 31 of the one-side holding body 8 is rotated to close each ventilation hole 10 and the stop valve 32A is opened. After that, the slurry-like substance a is charged into the molding frame 1 by the solvent suction means 27 through the sandwiching bodies 8 and 15 on both sides together with the filling by the filling means 25 under pressure, or alone under reduced pressure. Next, the shutter 31 is pivotally operated to open each vent hole 10 of the one-side holding body 8, and at the same time, the filling means 25 and the solvent suction means.
The stop valves 25D and 32A of 27 are closed, and while supplying heated air from the heating element 26, the solvent suction means is provided via the hollow holding body 15 on the other side.
By sucking the solvent with 27, the slurry a can be solidified.

In each of the devices of the embodiments, the heating element 26 is the one-side holding member 8.
Although it is configured to be provided inside, a heating device is provided outside the one-side holding body 8 so that heated air is supplied to the warm air outflow holes 12, 12, ... Side of the one-side holding body 8 via a blower pipe. May be.
