[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a surface treatment method for a solid cosmetic. More specifically, the solid cosmetic surface treatment method, the surface treatment method used therefor, and the amount and state of adhesion of the powder to be subjected to the surface treatment of the solid cosmetic can be freely controlled and can be easily implemented. The present invention relates to a solid cosmetic obtained by the method.
[0002]
[Prior art]
Conventionally, solid cosmetics such as lipsticks and eye shadows containing glittering powders and the like have been provided. If glittering powders and the like blended in these cosmetics appear on the surface, cosmetics are provided. A visual effect can be enhanced by giving a gorgeous atmosphere to the appearance of the material, and a cosmetic effect by use can be predicted and expected, and a high added value can be given to the solid cosmetic.
[0003]
It seems simple to express such a glittering powder effectively on the surface of a solid cosmetic, but it was actually quite difficult. The reason for this is that when a flat cosmetic powder is mixed with a solid cosmetic base and filled and molded, the bright powder is positioned on the cosmetic surface with the flat surface facing. The probability that it looks the same as the time is very low, and the appearance similar to that at the time of use cannot be obtained. Therefore, in general, after molding a solid cosmetic once, an attempt has been made to separately treat the surface of the solid cosmetic with a blended glittering powder or the like to obtain the same appearance as when used.
[0004]
Conventionally, as a method for surface treatment of the surface of the solid cosmetic with powder, a method of immersing the solid cosmetic in a container containing the powder, or by dispersing the powder in a volatile solvent was obtained. A method has been used in which the powder dispersion is applied to a solid cosmetic using a spray or the like and then dried to volatilize the solvent.
[0005]
However, when the method of immersing the solid cosmetic in the powder is used, the powder may be attached to the surface of the solid cosmetic in an uneven state. It was difficult to control the amount and state of adhesion of the powder. In addition, when the powder dispersed in the solvent is applied by spraying, etc., the solvent is inevitably used, and since a drying step for volatilizing the solvent is also required, the work is not only complicated. In some cases, the facilities were large. Furthermore, the problem of difficulty in controlling the coating amount and the coating state still remains.
[0006]
[Problems to be solved by the invention]
Therefore, it is desired to develop a surface treatment method for a solid cosmetic that can freely control the amount and state of adhesion of the powder to the surface of the solid cosmetic and that can easily carry out such treatment. Providing such a method is a challenge.
[0007]
[Means for Solving the Problems]
In view of this situation, as a result of intensive studies on the surface treatment method for solid cosmetics, the present inventors have provided a closed space, and adheres powder in a state of scattering and movement in the space to the surface of the solid cosmetic. Thus, the inventors have found that the above problems can be solved and completed the present invention.
[0008]
That is, the present invention provides a surface treatment method for a solid cosmetic, characterized in that a powder in motion is attached to the surface of the solid cosmetic in a closed space.
[0009]
Moreover, this invention provides the solid cosmetics obtained by the said surface treatment method.
[0010]
Furthermore, the present invention provides a storage body having a closed space large enough to store a portion of the solid cosmetic to be surface-treated, an on-off valve attached to the closed space of the storage body, and a powder having a discharge port. A solid cosmetic surface treatment characterized by comprising a body supply means and a decompression means, the powder supply means and the decompression means communicating with the closed space, respectively, and discharging powder from the discharge port A device is provided.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
The surface treatment method for a solid cosmetic according to the present invention is a method in which the surface of the solid cosmetic is exposed in a closed space, and powder in a moving state is adhered thereto.
[0012]
In the present invention, the powder is attached to the surface of the solid cosmetic in that state, that is, without using other components such as a solvent. It is necessary to apply extra power.
[0013]
Examples of the method for bringing the powder into a moving state include the following methods. First, the inside of the closed space in which the solid cosmetic is set is sucked into a reduced pressure state. When an airflow containing powder is introduced into the closed space in this state at a certain angle, the airflow vigorously rotates along the wall surface of the system space. And, when the air flow containing such powder rotates vigorously, if the outside air is flowed in intermittently or intermittently from a part of the closed space, the movement of the flowing outside air is added to the violent rotation motion and disturbed. As a result, a random movement force is given to the powder and it becomes a movement state.
[0014]
In a state where the air flow containing the powder rotates, the powder hardly adheres to the surface of the solid cosmetic, but after applying a random kinetic force, the powder moves in a disjointed direction and flattenes on the surface of the solid cosmetic. It will adhere with the surface facing.
[0015]
In order to decompress the closed space, various decompression means such as a vacuum pump, an aspirator, and a dust collector can be used. In addition, a trap may be passed through in order to collect powder that has not been used for the surface treatment and to prevent the vacuum pump from clogging.
[0016]
In addition, air pressure containing powder is generated by the pressure difference, and this air current is disturbed to produce powder in motion, which is surface treated, so not only using reduced pressure but also generated by, for example, a compressor It is also possible to create an air flow containing powder using high-pressure air that is used, and use this.
[0017]
The direction of rotational movement of the airflow may be horizontal or vertical, and the introduction time of outside air is preferably extremely short, and the number of times is preferably increased by using a timer or the like. It may be done mechanically.
[0018]
Furthermore, in the above-mentioned closed space, there is provided a decorative member that can change the internal air flow, intentionally and non-uniformly adhere the powder to the surface of the solid cosmetic, or provide a design decoration. May be.
[0019]
On the other hand, examples of solid cosmetics that can be surface-treated by the method of the present invention include oily solid cosmetics such as lipstick, lip balm, lip gloss, and concealer, and powder solid cosmetics such as eye shadow, foundation, and white powder. Lipstick, lip balm and lip gloss are particularly preferred. What is necessary is just to manufacture these solid cosmetics by a conventional method.
[0020]
Moreover, as the powder used for the surface treatment, the shape, particle diameter, particle structure and the like are not particularly limited as long as they are usually used in cosmetics and can give decorativeness to the application site. For example, a plate shape, a spindle shape, a needle shape, a spherical shape, a particle size of 0.1 μm to 5 mm, a porous, non-porous particle structure, or an organic, inorganic, rigid, A powder having characteristics such as elasticity can be used.
[0021]
The kind of the powder subjected to the surface treatment is not particularly limited, but it is usually preferable to use a glittering powder. Examples of the glitter powder include titanium oxide-coated glass powder, titanium oxide-treated synthetic phlogopite, titanium dioxide-coated mica, titanium dioxide-coated bismuth oxychloride, iron mica titanium, bituminized mica titanium, carmine-treated mica titanium, Bright powder such as bismuth oxychloride, fish scale foil, mica titanium, iron oxide coated mica, pearl pigment such as organic pigment-treated mica titanium, metal powder such as aluminum powder, polyethylene terephthalate / aluminum / epoxy laminated powder, polyethylene terephthalate / Various glittering powders such as a lamellar agent such as a polyolefin laminated film powder and a polyethylene terephthalate / polymethyl methacrylate laminated film powder can be used.
[0022]
Of these glittering powders, it is preferable to use titanium oxide-coated glass powder and titanium oxide-treated synthetic phlogopite in terms of giving a strong shine and a high decorative effect, and using titanium oxide-coated glass powder. Is particularly preferred. The use of titanium oxide-coated glass powder is effective in that when a solid cosmetic is surface-treated, it can produce a shine while making use of the original color of the cosmetic surface.
[0023]
These glittering powders can be used alone or in combination of two or more as required. Further, the glitter powder may have been subjected to oil agent treatment, silicone compound treatment, fluorine compound treatment, metal soap treatment, surfactant treatment, amino acid compound treatment, water-soluble polymer treatment, etc. on the surface. Good.
[0024]
In the method of the present invention, the amount of powder used for the surface treatment is not particularly limited, but is preferably 1/5000 to 1/50, particularly preferably 1/1000 to 1/100, based on the weight of the solid cosmetic. If it is used within this range, a sufficiently brilliant atmosphere can be produced. In addition, when a sufficient amount is applied to cover the surface, the color of the cosmetic surface is hidden, so the color seen before use is different from the color after use, producing a mismatch at the time of use. It is also possible.
[0025]
The solid cosmetic may be in the form of a stick or a type filled into a dish-like container, and the form may be from solid to waxy or gelled. Furthermore, when the surface of the solid cosmetic material is difficult to adhere as it is, it is preferable to carry out the method of the present invention after performing an adhesion improving treatment. Examples of the adhesiveness improving treatment include a method of giving a certain temperature to the solid cosmetic, and a method of spraying or applying a material capable of improving adhesiveness such as various oil components.
[0026]
【Example】
Hereinafter, it demonstrates in more detail using drawing which shows an example of the apparatus which implements the surface treatment method of this invention. FIG. 1 is a schematic view of a solid cosmetic surface treatment apparatus 1 (hereinafter referred to as “treatment apparatus”) which is an embodiment for carrying out the treatment method of the present invention, and FIG. 2 is a longitudinal sectional view of a container 2. 3 is a cross-sectional view taken along the line AA ′ of the container 2, and FIG. 4 is a vertical cross-sectional view of the container 2 with the solid cosmetic 4 attached thereto. 5 is a perspective view of the decorative member 18, and FIG. 6 is a longitudinal sectional view of the container 2 with the decorative member 18 and the solid cosmetic 4 attached thereto. In the figure, 2 is a container, 3 is a closed space, 4 is a solid cosmetic, 5 is an on-off valve, 6 is a powder tank (powder supply means), 7 is a decompression pump (decompression means), and 8 is a trap. Show. Reference numeral 9 denotes a container opening, 10 a powder, 11 a vent, 12 a conduit, 13 a control valve, 14 a discharge port, 15 a suction pipe, 16 a trap valve, 17 a pressure sensor, 18 A decorative member, 19 is a hole, and 20 is a solid cosmetic container.
[0027]
As shown in FIG. 1, the surface treatment apparatus 1 is configured such that a container 2 having a closed space 3 is connected to an on-off valve 5, a powder tank 6, and a trap 8. As shown in FIG. 2, the container 2 has an opening 9, a closed space 3, a discharge port 14, and the like. As shown in FIG. 4, the surface on which the solid cosmetic 4 is to be processed is provided in the opening 9. It is mounted with facing.
[0028]
The tank 6 connected to the closed space 3 of the container 2 contains the powder 10 that is a raw material for surface treatment of the solid cosmetic 4, and when air is used as an air flow, It is preferable to provide the vent hole 11 in the upper part. In the surface treatment apparatus 1 shown in FIG. 1, two powder tanks 6 are installed. However, one or more than three powder tanks 6 may be used. If different powders 10 are accommodated in a plurality of tanks, the surface treatment can be performed with the plurality of powders. It is also possible to use a plurality of colors and types of powder 10 in one powder tank 6.
[0029]
The powder tank 6 and the closed space 3 communicate with each other via a conduit 12. As shown in FIG. 3, the discharge port 14 for the powder into the container 2 of the conduit 12 is preferably directed in a direction having a certain angle from the center. In this way, the powder 10 and the air flow supplied from the powder tank 6 through the conduit 12 to the closed space 3 can rotate along the wall of the closed space 3.
[0030]
Further, the conduit 12 may be provided with a control valve 13 for controlling the supply and the amount of the powder 10. If the control valve 13 is provided in the conduit 12, the powder 10 can be quantitatively supplied to the closed space 3 at an appropriate timing. Further, in the case where a plurality of powder tanks 6 are installed, if the supply amount of the powder 10 is intentionally varied, the solid cosmetic 4 can be subjected to non-uniform surface treatment.
The lower part of the container 2 is connected to the decompression pump 7 via a trap 8. The decompression pump 7 plays a role of sucking air in the closed space 3. Then, by sucking the air in the closed space 3, motion can be given to the airflow including the powder 10 discharged from the powder tank 6 through the discharge port 14, and along the wall of the closed space 3 as described above. It will rotate. The decompression pump 7 used is sufficient if it has a function capable of reducing the pressure to such an extent as to give the above-described motion.
[0032]
Also, some particles of the powder 10 gradually lose their kinetic energy in the closed space 3 of the container 2, but the powder 10 that has lost its kinetic energy does not adhere to the surface of the solid cosmetic 4. By the suction force of the decompression pump 7, it moves to the trap 8 and is collected here.
[0033]
An open / close valve 5 is installed in the closed space 3 of the container 2. The on-off valve 5 is normally “closed”, but after the inside of the closed space 3 is in a decompressed state and the air flow including the powder 10 starts rotating, the on-off valve 5 is intermittently or Opened intermittently. By opening the on-off valve 5, outside air is sent into the closed space 3, and the movement of the outside air is added to the rotational movement of the powder 10, so that the powder 10 is in a moving state in the closed space 3. And the powder 10 which became this movement state adheres to the solid cosmetics 4 located in the approximate center in the closed space 3. FIG. Furthermore, when the on-off valve 5 is closed, the inside of the closed space 3 is in a reduced pressure state, and the rotational motion of the air flow including the powder 10 is resumed. Thus, the powder 10 can be adhered by opening the on-off valve 5. In addition, the frequency | count of opening the on-off valve 5 is decided by the quantity of the powder 10 which should be made to adhere to the surface of the solid cosmetics 4, and its grade, and may be 1 time or multiple times. The on-off valve 5 may be opened and closed by installing a pressure sensor 17 in the closed space and operating in conjunction with the pressure in the closed space 3 or manually.
[0034]
An example of the procedure for performing the surface treatment of the solid cosmetic 4 using the above apparatus is as follows. First, the powder 10 used for the surface treatment is filled in the powder tank 6. In addition, the solid cosmetic 4 in which a portion to be processed is exposed from the solid cosmetic container 20 is attached to the opening 9 of the container 2.
[0035]
Next, the on-off valve 5 and the trap valve 16 are brought into a “closed” state, and the decompression pump 7 is switched on. As a result, the air in the closed space 3 is sucked and the pressure is reduced. When the control valve 13 is opened in this state, the powder 10 contained in the powder tank 6 is closed together with the air flowing in from the vent hole 11. Flow into the space. Since the discharge port 14 faces away from the center, the airflow including the powder 10 flowing from here starts to rotate along the wall surface of the closed space 3.
[0036]
When the closed space 3 is depressurized to a certain level, the pressure sensor 17 installed in the closed space 3 is actuated, and the on-off valve 5 interlocked therewith opens. If it does so, external air will flow into the closed space 3 from this on-off valve 5, and the flow of the airflow containing the powder 10 which has been rotating will be greatly disturbed, and it will become a turbulent flow. The turbulent powder 10 moves violently in a random direction and adheres to the surface to be treated of the solid cosmetic 4 mounted almost in the center of the closed space 3. Then, by performing such a turbulent flow forming operation as many times as necessary, the surface treatment of the solid cosmetic 4 with the powder 10 is performed.
[0037]
As shown in FIG. 6, if the decorative member 18 is provided in the closed space 3, the powder 10 attached to the surface of the solid cosmetic 4 has a striped pattern and becomes a design decoration.
[0038]
The decorative member 18 is not particularly limited in shape or material unless it can change the airflow in the closed space 3 and prevent the powder 10 from being attached to the solid cosmetic. Absent. For example, one or two or more plate-like members or rod-like members can be used. In particular, when the solid cosmetic 4 is a rod-like cosmetic, a slit-shaped hole 19 is provided as shown in FIG. The cylindrical member mounted so as to surround the solid cosmetic 4 can be used. The hole 19 may have various shapes such as a round shape and a star shape in addition to a slit shape, and surrounds the solid cosmetic 4 with a decorative member 18 such as a cylindrical member provided with the hole 19. By wearing in this way, various decorations can be applied to the solid cosmetic 4. Examples of the material of the decorative member 18 are metal, plastic, paper, and the like, which can be easily processed and can be mentioned as preferable examples.
[0039]
[Action]
In the treatment method of the present invention, the surface treatment is applied to the solid cosmetic using the change in the motion state of the powder due to the pressure change in the closed space. That is, the rotational movement of the powder formed by depressurizing the closed space is disturbed by the introduction of intermittent or intermittent outside air, and the random movement of the powder generated thereby makes it possible to The powder is adhered to the surface.
[0040]
【The invention's effect】
In the treatment method of the present invention, the surface treatment is applied to the solid cosmetic using means for attaching the powder in motion in the closed space. The state can be freely controlled, and surface treatment can be easily performed without using a large-scale apparatus.
[0041]
In the method of the present invention, since the random motion of the powder is used, the finished surface has a natural appearance. Moreover, since it does not use a solvent or the like, it is advantageous from the viewpoint of work environment.
[0042]
Therefore, the present invention is extremely useful as a means for surface-treating solid cosmetics such as lipsticks, eye shadows, lip balms, lip glosses, concealers, foundations, and white powders, and has high added value to the solid cosmetics. Is something that can be given.
