Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method and apparatus for solidifying cosmetic powder in which the powder is solidified in a pencil-shaped container or a stick-shaped mold.

<Conventional technology> Conventionally, generally available solid powders, such as various powder products applied to compacts, are those in which raw material powder filled in an inner tray is pressed and solidified by a pressing plate. However, when using this method, there is a drawback that powder is scattered because an applicator stick with a sponge or the like attached to the tip is used. In addition, pencil-type products are made by kneading powder with wax, oil, etc., molding the core into a stick shape, and bonding it together and holding it between shafts to form a pencil shape. Compared to solid powder, it has the disadvantage that it spreads and has poor makeup retention. In addition, there are stick-shaped powder products made by solidifying powder with gypsum, and pencil-shaped and stick-shaped powder products using water-soluble binders. Powder products using this gypsum have short pot lives and are difficult to manufacture because the gypsum hardens rapidly, lack uniformity, and have a poor texture when used. Powder products using water-soluble binders are
Although it is kneaded and compression molded into sticks of a predetermined diameter and dried, it has the disadvantage that drying takes a long time. Furthermore, pencil-shaped powder products have the disadvantage that they require an extremely complicated process of attaching dried stakes to a predetermined diameter and sandwiching them between shafts to form a pencil shape.

<Problems to be Solved by the Invention> In view of the above circumstances, the present invention provides a pencil-type or stick-type cosmetic that can be applied directly to the skin without using a sponge or applicator stick that is required when using conventional compact type cosmetics. The object of the present invention is to provide a powder solidification method and apparatus for easily and reliably manufacturing cosmetics.

<Means for Solving the Problems> One of the present inventions is to fill a pencil-type container or a stick-like mold with a slurry-like powder dispersion, and to fill the entire upper surface and lower surface of the powder dispersion with a slurry-like powder dispersion. The two sides of the powder dispersion are covered with a net, and the solvent contained in the powder dispersion is discharged and collected from the upper and lower nets while pressing the entire upper surface with the net, and the solvent is collected in a pencil-shaped container or Another invention is a method of solidifying powder in a stick-like mold, and another invention is an apparatus directly used for carrying out the first invention, which includes a plurality of pencil-shaped containers or a plurality of containers filled with a slurry-like powder dispersion. A powder dispersion filling device that is capable of retracting upward, which is equipped with a support stand in the center on which a stake-shaped mold having molding holes is vertically arranged, and an actuator for vertical sliding on the upper part of the support stand. In addition, in the upper frame of the powder dispersion filling device, there is provided an upwardly retractable press having a vertical sliding actuating device with a wire and a net on the lower end surface and connecting a discharge device to the upper portion. Fit the cylindrical body,
and a lower part provided with an actuating device for vertical sliding, which has a solvent-resistant gasket on the upper surface with a net and a plurality of holes through which the solvent passes, and has an atmospheric opening facing the discharge device at the lower end of the support base. The powder dispersion filled in the pencil-shaped container or the stick-shaped mold is transferred to the solvent by substantially mechanical pressure with a pressing cylinder descending from above. At the same time, the solvent squeezed out to the upper and lower positions is collected by a discharge device, and the powder is solidified in a pencil-shaped container or a stick-shaped mold.

<Example> The present invention will be described below based on the drawings of the example.

Figure 1 shows a device that uses a pencil-type container.
2 is a support stand that vertically supports a plurality of pencil container molds 2 having an appropriate wall thickness with openings 2a and 2b at the top and bottom, and the lower opening 2b of the pencil container 2 is placed in the lower part of the support stand 1 on the entire surface. A screen 3 of 100 to 350 mesh made of stainless steel, nylon, Tetron, etc. is interposed to block the air, and a solvent-resistant gasket 4 with holes 4a through which the solvent passes is interposed, and the air is retracted downward to have an atmospheric opening 18. A flexible solvent receiving container 5 is closely attached to the solvent receiving container 5, and a discharge device 17 is attached to the side of the solvent receiving container 5, which communicates with an actuating device 12 that slides up and down via a valve 16. Reference numeral 6 denotes a powder dispersion filling container which can be retracted upwards into which a slurry-like powder dispersion is injected and filled. 6 is placed in close contact with the support base 1, and on the top of the filling container 6 there is a stainless steel insulator 8 that supports the net 7, and the same net 7 made of stainless steel, nylon, Tetron, etc. as described above. A pressing cylinder 9 whose lower part is fitted is provided between the two, and an actuating device 10 which is vertically slidable is provided on the pressing cylinder 9 which can be freely retracted upward.
A discharge device 14 is attached via a valve 13.
Further, a vibration device 15 is installed on the support base 1, and the structure is such that vibration is applied to the entire slurry-like powder dispersion liquid.

Here, first, slurry-like powder dispersion A
Filling container 6 with an appropriate filling machine (not shown)
The liquid is injected from the top of the bottle, and quantitatively filled into the pencil-shaped container 2 and the filling container 6. In this case, a press cylinder 9 with a shield 8 and a mesh body 7 fitted into the filling container 6
The filling container 6 is removed (raised).

Thereafter, the actuating device 10 disposed on the pressing cylinder 9 is activated to lower the pressing cylinder 9, and the discharge devices 14 and 17 at the upper and lower positions are driven to open the valves 13 and 1.
6. Further, the vibration device 15 attached to the support table 1 is simultaneously driven to apply vibration to the entire powder dispersion A, thereby preventing dilatancy of the powder dispersion A and making the powder dispersion A uniform. That is, by the downward pressing of the pressing cylinder 9, the solvent Aa contained in the slurry-like powder dispersion A in the filling container 6 and the pencil-shaped container 2 is squeezed and discharged through the nets 7 and 3 located above and below. However, they are collected by discharge devices 14 and 17, respectively, while only powder A' solidifies in pencil-shaped container 2. Incidentally, even without this vibrating device 15, it is possible to mold a solid product only by pressing the pressing cylinder 9. However, the pressing time will be increased slightly.

Next, after solidification, the actuating device 10 and the actuating device 1
1 are operated in sequence to raise the net body 7, the pressing cylinder 9 with the resist 8, and the filling container 6 one after another and separate them from the support base 1. On the other hand, by activating the actuating device 12, the solvent receiving container 5 is
is lowered and separated from the support base 1, and the net body 3 and packing 4 are removed. Thereafter, the pencil-shaped container 2 is removed from the support stand 1 and subjected to prescribed processing to obtain a product. As shown in FIG. 3, this product has a structure in which powder A' is solidified and packed in a pencil-shaped container 2.

FIG. 4 shows an apparatus using a stick-like mold. In this case, the mold 19 is
It has a plurality of molding holes 21 for obtaining A', and is fixed to the support base 1. The other configurations are the same as those for using the pencil-type container, so a description of the configuration will be omitted.

Here, as in the previous case, the slurry-like powder dispersion liquid A is quantitatively filled from the upper part of the filling container 6,
The molding hole 21 and 6 parts of the filling container are filled. After this, the solvent is released into the mold 19 by downward pressing of the pressing cylinder 9.
Aa is squeezed out and only powder A' solidifies. Of course, even here, the mesh bodies 7 and 3 are interposed above and below the mold 19. Furthermore, this solidified powder A′ is
As a product, it is used in combination with a feeding container 20 as shown in FIG.

<Effects of the Invention> As described above, the method and apparatus for solidifying cosmetic powder of the present invention include filling a fixed amount of a slurry-like powder dispersion directly into a pencil-type container or a stick-like mold, and dispersing the powder. The upper and lower sides of the liquid are covered with a net, and the solvent is discharged and collected while pressing the entire upper surface with the net, which solidifies the powder in the form of a pencil or stick with uniform density. can be obtained easily and reliably. Therefore, when using a pencil-type container, by sharpening the tip of the pencil, the coating material can be coated uniformly as it is, and in the case of a stick-type container, it can be inserted into a feeding container or the like to uniformly coat the coating material. In addition, this device has a special configuration that discharges the solvent in the powder dispersion liquid from the nets on the upper and lower sides. Solvent clogging of liquid will be cleared. That is, by having two solvent outlet ports, it is possible to handle even a powder dispersion containing many fine particles, and the solidification time can be shortened. In addition, if a small amount of solvent remains in the powder inside the pencil, it is possible to remove all the solvent by drying it at a temperature that corresponds to the boiling point of the solvent used, and the solidified powder will be stronger and more durable. It is something that gives you a strong core.
