Description

Manufacturing method of injection product using radial multi-injection and mascara brush manufactured by the same method {The mascara brush and manufactured goods using multi-molding of a radial shape}

The present invention relates to a method for manufacturing an injection product using a radial multiple injection and a mascara brush produced by the method for producing a product by injection in multiple. In particular, it is possible to produce a variety of products, but not to complete the product with a single injection, but in order to accommodate the aesthetic sense, to complete the product by proceeding a plurality of injections sequentially by changing various materials or colors with different melting points. It is an injection product manufacturing method using radial multi-injection which finishes injection products in the direction of increasing the thickness based on the center point, and mascara brush manufactured by the method.

Generally, mascara is a kind of cosmetics used by women to apply mascara liquid of various colors on the eyelashes to enhance the aesthetics of the eyes. The mascara is largely composed of a container in which the mascara liquid is stored, a handle for opening and closing the container, a rod-shaped bar stick protruding from the lower part of the handle, and a brush formed on the brush bar. Alternatively, the mascara liquid is applied to the brush by separation.

In particular, the mascara brush formed as described above is a volume (volume: effect to make the eyebrows look rich), curl (Curl: the end of the eyebrows to be rolled up according to the length and shape of the hair Effects), Long lash (Long lash: make the eyebrows look longer), Clean (Clean: make the eyebrows do not clump), etc. It is produced for various functions.

Conventionally used mascara brushes usually have various lengths, such as circular, triangular, or scalloped, based on the wire axis in the center of the cross section by twisting the hairs of a brush having a certain length with two strands of wires. It is manufactured to have the effect of volume, curl, rolllash or clean on the cross-sectional shape of the brush, respectively.

The basic role of the mascara brush is to be excellent in the combing effect by the brush so that the viscous mascara liquid is evenly applied to the eyelashes and the eyelashes are not entangled with each other. The amount of mascara liquid is radiated between the hairs to give a sense of volume to the eyelashes, but due to the viscosity of the mascara fluid, the eyelashes are bundled together to clean the eyelashes using a separate grooming device or the mascara liquid There is a discomfort to erase and make up again.

1 is a front view showing a state in which a coating brush and a grooming brush are separated as a mascara brush according to the prior art, and FIG. 2 shows a front view of another type of mascara brush according to the prior art.

As shown in the drawing, the application brush 3 is a means for receiving and applying mascara liquid to the eyelashes, and the application brush 3 is folded at the center of a plurality of hairs 31 having a predetermined length. After interposing in the orthogonal direction between the wires in a state, when the wire is twisted a predetermined number of times in a spiral, the wools 31 are radially fixed to the wire shaft 21 formed by the twisting of the wires.

In addition, one side vertical direction of the coating brush 3 is formed by cutting the hair 31 in a state fixed by the wire shaft 21. Then, the coating brush (3) formed as described above is fixedly coupled to the lower portion of the brush rod to be integral with the brush rod.

The grooming brush 4 is a means for cleaning the eyelashes in which the mascara liquid is buried by the application brush 3, and a comb 42 having a comb shape is protruded to the outside of the fixing table 41.

The fixing stand 41 is for fixing the comb part 42 to the cutout part 32 of the coating brush 3, and is formed around the outer circumference of the outer circumference of the handle bar, It is formed in the same or slightly longer length than the wire shaft 21 protruding to the lower part of the rod to be integrated.

In addition, an upper end of the fixing stand 41 has a fitting hole 44 formed to insert the wire shaft 21 so that the fixing stand 41 is integrated with the application brush 3, and a lower end of the fixing stand 41 is formed. The fitting groove 43 is formed so that the lower end of the 21 is inserted and fixed, and the fixing stand 41 should be located at a cut portion formed between the hairs 31 of the application brush 3, so that the fixing stand ( Between the fitting hole 44 and the fitting groove 43 of the 41 is supported by the side wall so that the holder 41 is formed in the "c" shape and its cross-sectional shape corresponds to the shape of the cut portion 32 It is shaped like a fan. The comb 42 is formed to protrude in the form of a single comb in the vertical direction to the outer peripheral surface of the side wall 45 of the holder 41, to comb the eyelashes, the comb 42 of the application brush (3) The hair 31 is branched in the vertical direction of the side wall 45 by a length fixed to the wire shaft 21 to form a line, and the comb teeth of the comb 42 have the same material as that of the holder 41. It is formed of synthetic resin and formed thicker and harder than the hair 31 forming the application brush 3, and the comb teeth and the comb teeth constituting the comb 42 are formed in a line at predetermined intervals, and the cleaning brush 4 ) Is shaped like a comb. However, by manufacturing and assembling the application brush 3 and the grooming brush 4 as in the prior art, there is a problem in that a large cost is generated to prepare manpower and equipment according to the assembly process.

In addition, in order to manufacture the coating brush 3, a plurality of hairs 31 having a predetermined length is interposed between a pair of wires, and then the wires are spirally twisted to form the hairs 31. It must go through a complex machining operation such as to be radially fixed to the, and the cleaning brush (4) is injection molded through a separate mold process from the above-described work process, and must be equipped with a separate mold equipment, The overall equipment cost for producing the mascara brush is increased, as well as the productivity is reduced due to the complex production line.

The present invention relates to a method for manufacturing an injection product using a radial multiple injection and a mascara brush produced by the method, which produces a product by injection in multiple, but to produce a variety of products, but not to complete the product in one injection, but aesthetic sense The method of completing the product by proceeding a plurality of injections in sequence by changing various materials or colors with different melting points for accommodating more specifically. More specifically, radial multiple to complete the injection product in the direction of expanding the thickness based on the center point. An injection product manufacturing method using injection and a mascara brush manufactured by the method are provided.

According to the present invention, a method of manufacturing an injection product using a radial multi-injection, after injection of a central part, is radially injected gradually from the center point to the outside or by using an insert molding technique and induces triple injection to five injection. Comprises completing the form of; In attempting the multiple injection, it is configured to include injection molding using different colors.

In addition, the mascara brush using the radial multi-injection of the present invention, the handle 101 is made of a solid material extending to the center of the handle 101 is formed with a screw portion (A) that is screwed to the container through the injection handle (101) ) Is formed together, and the comb molded part 130 of the same or relatively softer material is molded to the outside, and the brush molding part in which the myriad hairs 121 of the softest material are injected into the outermost part integrally. Injection molded in triplicate to make 120; The comb molded part 130 is injection-combined or insert molded to the outside of the brush stem 103; The comb forming unit 130 is configured to include one to four sections.

In addition, the mascara brush using the radial multiple injection of the present invention, the hair 121 of the brush molded part 120 to form a twig of the eye crystal shape to improve the absorption of mascara liquid; The brush body 110 is made of any one material selected from elastomer, silicon, plastic series; The handle 110, the comb molded part 130 and the brush molded part 120 is configured to include those that can be formed in the same or different colors selected, respectively.

According to the present invention, a method of manufacturing an injection product using multiple injections and a mascara brush manufactured by the method can produce an integrated product having various colors, and thus have excellent durability and excellent aesthetics.

According to the present invention, an injection product manufacturing method using a radial multiple injection and mascara brush manufactured by the method can be used to redecorate the eyelashes with a more delicate hair, and the texture thereof is soft so that the eyelashes or the surroundings of the eyes are not injured.

The present invention relates to a method for producing a variety of products through a multi-injection method and a mascara brush produced through the same. Therefore, the configuration and operation of the present invention with reference to the drawings shown in detail.

The present invention injects the central part radially and gradually injects from the center point to the outside gradually or utilizes the insert molding technique to induce triple injection to five injection and complete the shape of the product. In other words, the injection molding is carried out a plurality of times, the pre-injection molding of the center portion of the product, the injection molding of a variety of materials or a variety of different colors of material to the outside to complete the product by adding.

3 and 4 is a view showing the manufacturing process of the mascara brush, when explaining the manufacturing method of the present invention by way of example, the first to produce the handle 101, the center of which extends long from the handle 101 The molded brush 103 is injection molded at the same time. At this time, the handle 101 is manufactured by using a synthetic resin of a more robust and hard material to be screwed with the container. Next, the comb molding part 130 to be located on the outer circumferential surface of the brush stand 103 is injection molded. At this time, in the present invention, as shown in FIG. 3, the comb forming unit 130 may be first molded by insert molding the comb forming unit 130 by double (two-stage) injection molding, or as shown in FIG. 4. ), The comb molded part 130 may be injected twice (two steps). And then injection molding the body 110 and the parent 121 to be located at the outermost portion. As such, the present invention attempts to eject in three (three steps) to complete a single article. Such a product can be any article that can be manufactured through injection, and the reason for this molding in the present invention is as follows.

First, all synthetic resins have different melting points and different temperatures at solidification. Therefore, it is impossible to inject and inject synthetic resins having different melting points into one mold. Of course, conventionally, in order to solve such a problem, after injection molding separately, it was completed by a method of assembling each other. However, the present invention completely solves these problems, and injects synthetic resin melts having different hardnesses to produce highly durable articles for each component.

Second, injection molding is the operation of floating the shape of the internal space of the mold by injecting a single material into the mold. Therefore, the resin melt that must be introduced into one mold is limited to one color. This has the potential to reduce the aesthetics of the finished product. Therefore, the present invention was born in order to complete an excellent product in one aesthetic sense.

As a result, the present invention is characterized in that injection molding using different materials and colors in attempting the multiple injection.

Next, the present invention is a mascara brush, the handle 101 of the solid material extended to the center (?) Of the handle 101 is formed by the screw portion (A) is screwed to the container through the injection handle 101 and Brush forming part 120 is formed together, the comb molded part 130 of the same or relatively softer material is molded to the outside, and countless hairs 121 of the softest material relatively injected to the outermost part integrally The injection molding is carried out in 3 to make). That is, as shown in FIG. 3, the handle 101, which is screwed to the mascara container and the screw, is molded by injection, but together, the handle 103 is formed to protrude upward from the center of the handle 101. At this time, the handle portion 101 of the present invention must be screwed to the container, and more rigid material to achieve the support of the comb 130 and the brush molded part 120 to be attached to the outside perfectly It must be made of synthetic resin. Therefore, the synthetic resin injected during injection molding in the primary mold should be filled with a synthetic resin of a more rigid material.

And the outer peripheral surface of the handle 101 is injected to the comb molded part 130 which is the next component of the present invention, which can be produced in the manner of FIG. That is, the method of Figure 3 is to insert the injection molding method of the injection molding in a state in which a separate comb molded part 130 by injection molding and inserted into a mold for triple (3 steps) injection, 2 is a method of pouring the injection liquid to surround the handle 103 of the handle portion 101 as a whole to the injection. That is, the handle 101 and the comb molded part 130 are manufactured through two injections. By the way, in the mascara brush, such as the present invention, the comb molded part 130 is preferably a material that is somewhat firm. Compared to the pre-fabricated handle 101 and the handle 103, it may be as firm as possible, but may be made of synthetic resin having a somewhat low hardness. In the present invention, it is also possible to use a material of different hardness in order to proceed the injection to each step separately.

Next, the present invention finally injection molding the body and the parent 121. That is, as shown in FIG. 3, a very soft synthetic resin material is poured into the mold to the outside of the insert molded comb 130 together with the lead 103. After all, the main gist of the present invention is to produce a mascara brush, which is a finished product by applying an injection in a radially extending manner from a central center line. Of course, a slight difference in the injection method may occur in FIGS. 4 and 3, and the comb forming unit 130 may be selectively used in two ways, which may be injection-combined or insert molded to the outside of the lead 103. will be.

Meanwhile, in the present invention, as shown in FIG. 5, the comb forming part 130 is preferably formed in 1 to 4 sections. That is, the comb part 138 protruding from the comb forming part 130 can be manufactured in the state which protruded only in 1 direction, and may be produced in the state which protruded all 1 to 4 rooms. It is desirable to manufacture symmetrically while maintaining only a constant angle. By the way, the mascara as in the present invention can form the cross-section of the body 110 and the handle 103 in the form of circular, elliptical and polygonal in the aesthetic or manufacturing process. That is, as shown in Figure 6, it can be produced by forming the body 110 and the handle 103 of the various polygonal shape, it is also possible to manufacture the body 110 and the handle 103 of the circular or oval shape. In this case, the hair 121 protruding from the body 110 is preferably micro mold injection.

Therefore, the manner of this micro mold injection to be used in the present invention will be briefly described.

The micro mold is a mold used for processing a micro component, and the well-known technique is a structure forming method (LIGA: lithographie, Galvano-formung, Abformung) and silicon micromachining techniques.

Briefly described, the structural molding method is a molding method that can make a high structure ratio microstructure by deep lithography and electroplating using X-rays, and in detail, first, an X-ray photosensitive agent such as PMMA A photoresist layer is formed on the substrate with a desired thickness (about 0.1-1.0 mm), patterned using heavy metals such as gold as an X-ray absorber, and then used as a mask.

Then, the resist is exposed to X-rays (SOR light) emitted from the synchrotron. At this time, since the X-ray SOR light is excellent in straightness, resolution, and transmittance, exposure to a thick resist with submicron precision or less is possible.

Then, when the structure of the resist is obtained through development, it is contained in an electroplating solution to form an electroplating layer on the conductive substrate.

By using the plating layer as a mold, the mold can be stamped onto the plastic by injection molding. In addition, based on the plastic mold made of the injection molding, a metal structure may be made again by electroplating, or ceramic powder may be made by sintering ceramic powder into plastic.

Then, the silicon micromachining technology will be described in detail, by coating a film on the silicon substrate, the mask pattern on the surface of the mask pattern is reproduced through the development and printing process, nicking based on the duplicated pattern, unnecessary parts The process of removing and repeating the heat treatment and doping process to produce the desired micro components.

When the micro mold as described above is used, the brush bristles are made much thinner than the bristles of conventional bristles, and the bristles are very soft and absorbent, thereby greatly improving the usability. In addition, since the body and the brush molded part are integrally formed by injection molding, the manufacturing process of the mascara brush is greatly shortened, thereby reducing the production cost. In addition, the shape of the mascara brush is not limited to a specific shape can be molded in a variety of shapes has the advantage that can be advantageously product design in terms of aesthetic or practical aspects.

The hair 121 produced using such a micro mold has a thickness of 0.01-0.2 mm. More preferably, when it is thinner than 0.01-0.09mm, it is difficult to hold mascara liquid and thus difficult to paint on the eyelashes. When thicker than the thickness, the mascara liquid is difficult to lift an appropriate mascara liquid, making makeup difficult. Thus, maintaining the above thickness has been demonstrated through a number of experiments by the applicant of the present invention.

Next, as shown in (e) and (f) of FIG. 6 shown in the present invention, it is preferable to form a twig of the eye crystal shape of the hair 121 of the brush molded part 120 to improve the absorbency of mascara liquid. Do. By enlarging the cross-sectional area, it is a consideration to absorb a larger amount of mascara liquid and to apply the absorbed mascara liquid to the eyebrows easily without irritation.

Meanwhile, in the present invention, the brush body 110 is preferably made of any one material selected from elastomer, silicon, and plastic series. This is also an empirical rule produced through many experiments, and in the mascara brush of the present invention, the handle 110, the comb molded part 130 and the brush molded part 120 may be formed in the same kind and different kinds of colors, respectively. . As a structural feature of the present invention, the color of the injection solution to be injected during the first step injection and the injection solution to be injected during the second step injection in the present invention completes one product through three or more multiple injections. Color and the color of the injection solution to be injected during the third stage of injection is not important. Of course, as mentioned above, the hardness of the material is also not important. Depending on the aesthetics or the use of its components, multiple injections can be made to achieve optimal finished products.
