Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a solidifying device for powder cosmetics, particularly powder cosmetics filled in dish-shaped containers.

[Prior Art] It is well known that an inner plate or other dish-shaped container fitted into a compact cosmetic container is filled with solidified powder cosmetics such as solid white powder or blusher.

These solidified cosmetics are produced by using a solidifying device in which a mounting table and a pressing body are arranged above and below so that they can be approached to each other, and a dish-shaped container filled with powdered cosmetics mixed with a small amount of fats and oils is placed on top of the solidifying device. It is manufactured by placing the powder cosmetic on a mounting table, bringing the mounting table and the pressing body close to each other, and pressing and solidifying the powder cosmetic.

At that time, if air is enclosed in the solid cosmetic, not only will the air inside expand and the center of the surface swell when the pressure is released, but the enclosed air will expand and contract due to changes in the ambient temperature during storage. As a result, cracks and destruction occur, reducing the product value. In addition, because the internal density becomes uneven, when wiped with an applicator such as a puff, a large amount of low-density parts adheres to the surface, making the surface uneven, resulting in uneven coating. This results in the inconvenience of easily causing

Therefore, in order to eliminate these drawbacks, it has been considered to measure the evacuation of air present in powder cosmetics during press solidification (Japanese Patent Publication No. 30-7450, Japanese Patent Application Laid-Open No. 48-33995). (see official bulletin).

[Problems to be Solved by the Invention] However, the solidification device proposed in Japanese Patent Publication No. 7450/1980 fills powder cosmetics into a dish-shaped auxiliary container with a number of holes at the bottom. Since the air contained in powder cosmetics is only pushed out through the holes, the exhaust efficiency is extremely poor, and not only does air tend to remain, but the auxiliary container may be left in the container as is. Since the product is made by fitting into a dish container, a large number of auxiliary containers must be prepared, resulting in poor productivity and economy.

On the other hand, the solidifying device disclosed in Japanese Patent Application Laid-Open No. 48-33995 has a large number of through holes in a pressing body that presses the surface of powder cosmetics filled in an upwardly open dish-shaped container. The air in powdered cosmetics is discharged through the holes, and unlike the solidifying device shown in Japanese Patent Publication No. 1974-7450, it does not require a special auxiliary container and can be stored in a compact. Powdered cosmetics can be directly filled into a dish-shaped container and solidified as is, which is economical; however, as mentioned above, air is only expelled through the holes, so the exhaust efficiency is poor. It has the drawback of being extremely bad and easily allowing air to remain.

In addition, all of the solidification devices described above directly push out the air contained in the powder cosmetics into the atmosphere and discharge them, so there is a risk that the fine powder cosmetics will scatter with the air and contaminate the surrounding area. There is.

The present invention was made in view of the above circumstances, and provides a solid cosmetic that solidifies uniformly and has a beautiful surface by completely expelling the air contained in the powder cosmetic through compression and suction. The present invention provides an apparatus for solidifying powder cosmetics, which is capable of obtaining the following properties and is also excellent in economical and environmental aspects during production.

[Means for Solving the Problems] The device for solidifying powder cosmetics according to the present invention comprises a mounting table on which a dish-shaped container with an open top is placed and a pressing body disposed above the mounting table, and the both are moved close to each other. In the powder cosmetic solidifying device for pressing and solidifying the powder cosmetic filled in a dish-shaped container on the placing table, an air permeable membrane is disposed between the placing table and the pressing body. Further, the pressing body is formed hollow, and a large number of small diameter through holes communicating from the lower surface to the hollow part are bored only in the bottom wall over the entire surface thereof, and a net body is laminated on the lower surface. The air intake device is characterized in that an intake device is connected to the hollow portion through a valve that opens only when the pressing body is pressing the pressing body.

[Function] During pressing, air in the powder cosmetic is discharged by the squeezing action of the pressing body and the suction action of the suction device.

Further, the lower surface of the pressing body contacts the surface of the powder cosmetic through the air-permeable membrane and the mesh without directly coming into close contact with the surface of the powder cosmetic, and the air in the powder cosmetic is discharged from the entire lower surface of the pressing body.

Furthermore, the valve of the suction device opens only when the pressing body is blocking the surface of the powder cosmetic, and prevents air intake while the pressing body is separated, thereby preventing the powder cosmetic from scattering.

Furthermore, a pattern is formed on the surface of the solidified cosmetic by the mesh body and the breathable membrane body.

[Example] Next, embodiments of the present invention will be described based on the drawings.

The drawing shows one embodiment of the present invention, and a solidifying device 1 for manufacturing a solid cosmetic mainly includes a mounting table 3 on which a dish-shaped container 2 with an open top is placed, and a pressing body 4 disposed above the solidifying device 1. It consists of

The mounting table 3 and the pressing body 4 are attached to drive rods 5 and 6 that move in the vertical direction by a suitable drive device, and are supported so as to be able to approach and separate from each other.

The pressing body 4 has a thick disk shape as a whole and has a diameter that allows it to be tightly fitted into the opening of the dish-shaped container 2, and is formed hollow, and only the bottom wall 7 has a hollow portion extending over its entire surface from the lower surface 7a. A large number of small diameter through holes 9 communicating with the holes 8 are bored at appropriate intervals. Further, on the lower surface 7a, a mesh body 10 made of, for example, stainless steel and having 10 to 20 meshes is laminated. Furthermore, an intake device 12 such as a fan type, piston type, or rotary type is connected to an exhaust hole 11 opened in the hollow part 8 through a conduit 13, and when the pressing body 4 is lowered into the conduit 13, That is, a valve 15 is interposed that opens only when the pressing body 4 is pressing the powder cosmetic 14 filled in the dish-shaped container 2. This valve 15 uses, for example, an electromagnetically driven on-off valve, and is opened and closed by a limit switch or the like that is activated when the mounting portion 3 and the pressing body 4 approach each other.

Further, between the mounting table 3 and the pressing body 4, a belt-shaped breathable membrane 16, which is made of cloth or paper and has breathability and is wider than the diameter of the dish-shaped container 2, is disposed. This breathable film body 16 is wound around a reel 17 and passes through guide rollers 18 and 19 to the mounting table 3 and the pressing body 4.
After passing between them, the film is wound onto a winding shaft 20 which is rotated intermittently by an appropriate drive device.

In order to use the solidifying device 1 having the above configuration, first, a powder cosmetic 1 mixed with an appropriate amount of oil and fat is prepared.
4 is placed on the mounting table 3, the mounting table 3 and the pressing body 4 are brought close to each other, and the powder cosmetic 14 is applied to the breathable membrane body 16 and the mesh body 10 with the lower surface 7a of the pressing body 4. Press from the surface through.

At this time, the air contained inside the powder cosmetic 14 passes through the air permeable membrane 16 and the net 10 that are in contact with the surface due to the squeezing action of the pressing body 4, and then passes through the through hole 9 into the hollow part. Pressed to 8. At the same time, the valve 15 opens and the suction device 12 creates a negative pressure in the hollow part 8, for example, about 0.01 to 0.3 Kg/cm ² , which is lower than atmospheric pressure. The trapped air is suctioned out, and the combination of extrusion and suction causes the air to be completely evacuated. In addition, the press body 4 and the powder cosmetic 1
The surface of 4 includes not only the breathable membrane 12 but also the mesh 10.
The powder cosmetics 14 do not come into direct contact with each other because they are in contact with each other, and the internal air is quickly and sufficiently discharged from the entire surface of the powder cosmetic 14, and the through holes 9 of the pressing body 4 are formed only in the bottom wall 7. Coupled with the fact that a large suction force can be obtained, the exhaust efficiency is extremely good, and solid cosmetics with uniform density throughout can be easily obtained. Furthermore, the net body 10 is formed by sucking up the powder cosmetic 14 into the through holes 9 by the suction device 12 and forming a large number of convex portions having the diameter of the through holes 9 on the surface of the powder cosmetic 14. In addition to preventing the solid cosmetic from becoming a solid cosmetic with low commercial value, a unique pattern is formed on the surface of the powder cosmetic by the network 10 and the breathable film 12, and therefore the mesh 10 and the breathable film By appropriately selecting 12, a solid cosmetic having an excellent surface design can be obtained. In particular, since the mesh body 10 is separate from the pressing body 4, it can be repaired by replacing only the mesh body 10 using one pressing body 4, which is economically advantageous, and the design can be easily changed. It is.
Furthermore, since the surface of the powder cosmetic 14 is covered by the air-permeable membrane 12 when pressed, the mesh 10 is not stained or clogged by the powder cosmetic 14.

When the molding is completed, the placing table 3 and the pressing body 4 are separated from each other, the dish-shaped container 2 is taken out from the placing table 3 by an appropriate means, and a new dish-shaped container is filled with the next new powder cosmetic 14. 2 and solidify the powder cosmetic 14 by the same operation as above.

[Effects of the Invention] In the present invention having the above configuration, the air in the powder cosmetic is discharged by the squeezing action and the suction action, and the lower surface of the pressing body is exposed to the powder through the breathable membrane and the net. By contacting the surface of the body cosmetic without coming into direct contact with it, the air in the powder cosmetic is discharged not only from around the through hole formed on the lower surface of the presser but also from the entire surface. By drilling only in the bottom wall, it is extremely efficient and completely degassed in a short period of time without drawing in outside air, without leaving any air behind.As a result, the molded solid cosmetic is uniform throughout the interior. There is no uneven coating during use, and there is no risk of cracking or destruction due to expansion and contraction of internal air during storage.

Further, the intake device opens a valve only when the pressing body is pressing, and prevents air intake while the pressing body is separated, thereby preventing scattering of the powder cosmetic into the atmosphere.

Furthermore, it is possible to form a unique pattern on the surface of the solidified cosmetic by using the mesh and the breathable membrane, and it is possible to produce a solid cosmetic that has excellent commercial value in terms of appearance. Since the mesh body is separate from the pressing body, repairs can be made by replacing only the net body using one pressing body, which is advantageous from an economic point of view, and the design can be easily changed.
