Description

A method for preparing cosmetic composition having three dimensional design and multi-color}

The present invention relates to a method for producing a cosmetic having a variety of colors and three-dimensional pattern as a cosmetic contained in a dish-shaped container.

There are two types of makeup products that use dish-shaped containers. There are a dry method mainly for compression molding and a molding method for molding by pouring into a container or a mold. Dry shaping is a common method of shadowing and twin cakes. These products use powders containing pigments and binders to maintain their shape. As a method of forming by the dry method, a method using a press is mainly used.

In addition, a technique for commercializing a variety of colors in one container has been reported in the prior art (Korean Patent Publication No. 2008-0050756, 2008-0050755, 2003-0024001, 1997-0009771). According to this, it was possible to make products with various colors or embossed patterns. The embossing of the makeup products by the molding method was possible to multi-dimensional three-dimensional pattern only solid products at room temperature having a wax content of more than 10%, such as lipstick. However, multicolor embossing was not possible for products with lower hardness than lipsticks such as lip gloss and skin covers. This is because the manufacturing process of products with lower hardness than lipsticks such as lip gloss or skin cover usually uses the method of filling the contents from the top, so it has a flat shape without embossed pattern. In the mold release process, there was a problem in embossed pattern molding using the molding method because the contents were not released from the mold.

On the other hand, when looking at the trend of using lip makeup, consumers have a high preference for a product in which a lipstick and a lip gloss are packaged together in one dish (container), but they cannot solve the technical problem of simultaneously molding a lipstick and a lip gloss using a molding method. There is a situation.

The present invention not only satisfies the needs of consumers who can use various contents in a single product, but also provides a method of manufacturing cosmetics to satisfy consumer preferences for products having a beautiful appearance by distinguishing them from conventionally manufactured products. The purpose is to.

Specifically, an object of the present invention is to provide a method for producing a multi-color three-dimensional pattern cosmetics comprising two or more cosmetics having different colors in a single container and each having a three-dimensional pattern.

In addition, the present invention has another object to provide a manufacturing method of a multi-color three-dimensional pattern cosmetics improved in terms of cost or manufacturing time by proceeding in a single process in a single molding frame in terms of manufacturing technology. .

The present invention has been devised to overcome the problems described above to introduce the cryogenic cooling process of -150 ℃ to -15 ℃ to form a pattern of the relief using the engraved mold and to ensure sufficient hardness for release. In addition, it was possible to reduce the damage to the contents through the release agent and to create an embossed pattern without damage to the contents by using a flexible silicone (silicone), rubber (rubber), etc. as a molding frame.

The present invention specifically provides a method for producing a multicolor three-dimensional pattern cosmetic comprising the following manufacturing step and a multicolor three-dimensional pattern cosmetic prepared therefrom.

a) coating a release agent on an inner molding frame in which an intaglio pattern is formed so as to have an embossed pattern after the release (S1);

b) a step of combining the cosmetic filling container with an upper end opened upside down on the inner mold (S2);

c) inserting the cosmetic injection nozzle through the lower end of the cosmetic injection container, and filling and cooling the first cosmetic to the intaglio pattern forming portion of the mold (S3);

d) filling and cooling the second cosmetic having a different color from the first cosmetic in the container (S4); And

e) Release step (S5) of cooling the filled cosmetics at a temperature of -150 ° C to -15 ° C and then separating the mold.

Hereinafter, the present invention will be described in detail.

At this time, if there is no other definition in the technical terms and scientific terms used, it has a meaning commonly understood by those of ordinary skill in the art. In addition, repeated description of the same technical configuration and operation as in the prior art will be omitted.

1 is a process block diagram showing a cosmetic manufacturing process according to the present invention, a multi-color three-dimensional pattern cosmetic manufacturing method according to the present invention is a) release agent coating step (S1), b) mold and container bonding step (S2), c ) Cosmetic primary filling step (S3), d) cosmetic secondary filling step (S4) and e) release step (S5).

Release agent coating step (S1) is a step of coating the release agent on the inner mold to be formed so that the intaglio pattern is formed to have the relief pattern after the release.

The inner mold can be released without damage to the contents by using a flexible silicone (rubber), rubber (rubber) or a mixture thereof. ABS resins (acrylonitrile butadiene styrene copolymer), PET (Polyethylene Terephthalate), PP (Poly propylene), etc. are not stretchy, and the molding molds do not contain the contents. The inner mold can be designed into a desired shape and can be made of one or more pieces, and can be inserted into the outer mold to be selectively inserted into each part according to the three-dimensional pattern to be formed. It is preferable that the depth of the intaglio pattern is formed in the inner mold is 1 to 10mm, which is less than 1mm flows to the side of the contents during the primary filling, the shape may be disturbed when exceeding 10mm, the boundary of the finished product is disturbed Loss can be a disadvantage.

In order to further improve the releasability with the cosmetics, it is preferable to use a dimethicone, which is a siloxane-based material, and a release agent coated with a cosmetic is particularly excellent in high viscosity dimethicone of 100CS or more.

The molding mold and container coupling step (S2) is a step of inverting the cosmetic container filled with the upper end is turned over on the inner mold to combine. The cosmetic filling container does not need to be limited in form, but it is inverted and coupled to the mold so that the upper part is open and the cosmetic injection nozzle can be inserted into the lower part. The container may have a cylindrical or quadrangular shape having an upper end and a lower end open. Preferably, the bottom end of the container is formed with a plurality of nozzle insertion holes formed therein. When a plurality of nozzle inserts are formed, the diameter of the nozzle insert is preferably 1 to 4 mm. If the diameter of the nozzle insertion hole is less than 1mm, the size is about 1mm to 4mm is suitable, and if it is less than 1mm, the diameter of the filling nozzle should be small. Cosmetic cosmetics have a disadvantage in appearance.

The cosmetic primary filling step (S3) is a step of inserting a cosmetic injection nozzle through the lower end of the cosmetic injecting container and filling and cooling the first cosmetic in the intaglio pattern forming part of the mold (S3). More preferably, the first cosmetic is filled and cooled in the intaglio pattern forming portion of the molding die through a nozzle insertion hole formed in the bottom surface of the bottom of the container.

The second step of filling the cosmetic (S4) is a step (S4) of filling and cooling a second cosmetic having a different color from the first cosmetic into the container. Between the cosmetic primary filling step (S3) and the cosmetic secondary filling step (S4) may further have a step of injecting and cooling a different color or different kinds of cosmetics.

The first cosmetic and the second cosmetic may be independently selected from a skin cover for lipstick, lip gloss, blusher or shadow face makeup. Lip makeup cosmetics, such as lipstick and lip gloss, preferably contains 1 to 30% by weight of the dextrin fatty acid derivative. When the content of the dextrin fatty acid derivative is 1% by weight or less, it is difficult to maintain a three-dimensional pattern because it is flowable at room temperature, and its useability is not good at 30% by weight or more, so it is not too hard or glossy.

Cooling of the cosmetic primary filling step (S3) and the cosmetic secondary filling step (S4) is preferably carried out in the temperature range of -15 ℃ to 0 ℃. If the cooling time is longer than 0 ° C., the processing time is increased, and at −15 ° C. or lower, the surface gloss of the contents is lowered and the bonding strength with the secondary filling cosmetic is inferior.

The next step, the release step (S5) is a step of separating the mold after the cryogenic cooling of the filled cosmetics at -150 ℃ to -15 ℃, more specifically -70 ℃ to -40 ℃. When the cryogenic cooling temperature is less than -150 ℃, cracks may occur in the cosmetic or separation of the cosmetic 1 and the cosmetic 2 may occur, and at -15 ℃ or more, the cosmetic is clinging to the molding mold, the embossed pattern is disturbed during release.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are provided as examples to ensure that the spirit of the present invention to those skilled in the art will fully convey. Accordingly, the present invention is not limited to the embodiments described below and may be embodied in other forms. In the drawings, lengths, thicknesses, and the like of layers and regions may be exaggerated for convenience.

Figure 2 is a perspective view showing a molding apparatus of a lip gloss palette as an embodiment according to the present invention, Figure 3 shows a process flow diagram of a lip gloss palette as an embodiment according to the present invention, Figure 4 In one embodiment according to the present invention shows a process flow diagram of a lip gloss pallet of different shapes. The lip gloss pallet forming apparatus 10 according to the invention shown in FIG. 2 is simultaneously equipped with two or more nozzles 11, 12, 13 for multicolor simultaneous filling. Since the purpose is to fill a variety of colors in one container (internal dish), the nozzle may be provided in various ways from two to ten. The cosmetic filling container (inner dish) 20 may have a circular or various shapes as shown in FIG. 1, and in particular, the nozzle inserts 21, 22, and 23 for filling directly at the lower end of the container are directly formed at positions to create an embossed pattern. It is designed to be charged. The outer mold 3 and the inner mold 4 are molding molds for molding cosmetics. Preferably, a flexible material such as silicone or rubber is preferable. The inner molding frame 4 may be made of one or more pieces, and after the desired three-dimensional pattern is formed in the intaglio to be selectively inserted into each part. The intaglio patterning depth is preferably about 1mm to 10mm. The cosmetic filling container 20 is inverted and combined on a molding mold as shown in FIG. 1 before cosmetic injection. In the mold release process after cosmetic injection and cooling, the outer mold 3 and the inner mold 4 are released to the bottom 8 of the molding apparatus of the lip gloss pallet by a mold release device (not shown).

Referring to Figures 3 and 4 will be described a process for producing a lip gloss palette having a multi-color solid pattern.

The mold release agent 7 is coated on a part of the mold 3 and 4 to be in contact with the cosmetic. Preferred mold release agent (7) is dimethicone, and is particularly excellent in high viscosity dimethicone of 100CS or more. In the present invention, DOW Corning's DC 200 (350cs) was used. The release agent was coated on the mold by the aerosol spray method while heated to about 30 to 100 ℃. The temperature is 30 Below ℃, the release agent is aggregated and flows into the intaglio forming part of the inner mold, causing the disadvantage of distorting the shape of the contents. Above ℃ ℃ may reduce the uniformity of the coating thickness according to the shape of the intaglio pattern.

The next step is to combine the mold with the release agent coated mold. The vessel is inverted to engage the vessel with its top end down. As shown in FIG. 3, the shape of the container may be one in which a plurality of nozzle insertion holes are formed at the bottom of the bottom, or the bottom may not be formed at the bottom, as shown in FIG. 4. It is not necessary to limit the type and shape of the container, but it is more preferable that the nozzle insert is formed on the bottom surface in consideration of the ease of subsequent processing.

The next step may be to use two or more cosmetics in consideration of the change in color according to the type and pattern of cosmetics to be filled in the cosmetic filling step. The contents of the present invention can be applied to all the makeup cosmetics contained in a dish-shaped container (palette type), and in particular, the composition characteristics of the lip gloss used in the embodiments of the present invention are as follows. The pallet composition should maintain a hardness that does not flow at room temperature. In addition, since the surface gloss of the finished product should be excellent, in the present invention, 1 to 30% by weight of the dextrin fatty acid derivative was used. At 1% by weight or less, it was not flowable at room temperature, so the three-dimensional pattern could not be maintained. At 30% by weight or more, the usability was not good, so it was not too hard or glossy to apply with a makeup tool. 3 and 4 show that the first filling step and the second filling step to inject two colors of cosmetics. The primary filling step of the cosmetic is a process of selectively filling the contents only where the embossed shape is required, and in the first filling step, by injecting cosmetics of different colors into the nozzles 11, 12, and 13, different colors are used in one step. The three-dimensional pattern of can be formed. After filling the primary cosmetics 5, the primary filled cosmetics are not mixed with the cosmetics to be secondary filled, and the cosmetics are cooled at a temperature range of -15 ° C to 0 ° C to shorten the process time and improve molding quality. In addition, after filling the primary cosmetics, a process of injecting a different color or a different kind of cosmetic into a pattern forming portion on a mold for forming a three-dimensional pattern and then cooling may be repeatedly performed.

The second step, the cosmetic filling step, is a step of filling the second cosmetic 6 having a different color from the primary filling cosmetic 5 and injecting the cosmetic to the lower end of the container. The cosmetics having different colors may be the same kind of cosmetics as the primary filled cosmetics, or may be different kinds of cosmetics. For example, both the primary and secondary cosmetics may use lip gloss, the primary is lip gloss, the secondary is lipstick, or vice versa. After the cosmetics are completely filled in the container, it is preferable to cool the cosmetics in the temperature range of -15 ° C to 0 ° C as in the first filling step.

The next step is a release step of separating the molding mold and cosmetics, and separating the molding mold under the cosmetic molding apparatus by vacuum through a mold release device (not shown). This mold release step according to the invention cools the cosmetic to -150 ° C to -15 ° C, more specifically -70 ° C to -40 ° C, prior to release by the release device to release the low hardness content without disturbing the embossed pattern. The cryogenic cooling step is followed. In the present invention, a freezer of -60 ° C. is used, and simply, dry ice may be added to ethanol or a low temperature cooling device may be used by using liquid nitrogen. After cryogenic cooling, the mold is separated from the cosmetics (contents) using a vacuum apparatus. Since the cryogenic cooling process is performed, the mold is made of silicone or rubber material which is stable at low temperatures and has good elasticity.

Next, the process of inserting the cosmetics 30 and 40 having a multi-colored three-dimensional pattern released into the outer case 9 may be performed. At this time, a process for preventing the flow of cosmetics from the cosmetic exposed portion at the lower end of the cosmetic container (inner plate) 20, 25 may be added, for example, between the lower part of the container (inner plate) and the outer case (9). A sheet (not shown) may be interposed therebetween.

FIG. 5 is a photograph of a cosmetic having a multicolored three-dimensional pattern manufactured according to an embodiment of the present invention. FIG. 5 is a lip gloss palette photograph manufactured to have a different color between the three-dimensional pattern protruding from another three-dimensional pattern.

Cosmetic production method having a multi-color three-dimensional pattern according to the present invention can produce a cosmetic having a three-dimensional pattern of each embossed with a variety of colors in one container. The cosmetic preparation method according to the present invention is particularly applicable to compositions such as lip gloss or skin cover, which was impossible due to its low hardness and high adhesiveness, and to prepare a makeup cosmetic including lipstick and lip gloss in a single case.
