Manufacturing method of cosmetic case

The present invention relates to a method for manufacturing a cosmetic case, and particularly to a method for manufacturing a cosmetic case for manufacturing a cosmetic case with a metal plate.

In general, cosmetics are formed in various shapes such as round, oval, and shoot depending on their use, and are formed in various sizes according to portable, sample, and capacity, and in some cases, cosmetic containers include inner case, outer case, inner cover, and It is formed in various configurations such as an outer cover.

These cosmetic containers are painted in various colors according to their use and design, and even if one cosmetic container is a container formed of multiple configurations, each composition must undergo a process of painting a paint having different characteristics. .

Conventionally, the conventional method of painting a cosmetic container is to mount a cosmetic container on a chain spindle conveyor in which a rotating and stationary spindle is formed at regular intervals, and then remove static electricity and dust through a static elimination booth with a brush. After the coating is applied to the moving cosmetic container to be removed, a coating process of drying through a drying device is performed.

Thereafter, the cosmetic container after the coating process is separated from the conveyor, and a metal deposition process is performed by attaching a metal skin to the vacuum deposition apparatus, and the cosmetic container after the metal deposition process is mounted on the conveyor and painted through a painting booth spraying paint. When the painted cosmetic container is dried through a drying device, a painting process is performed, so that the painting of the entire cosmetic container is largely completed by three processes.

Currently, most cosmetic cases are used by injection molding a synthetic resin (plastic) material, and coating the color of the resin or the like.

In order to upgrade the cosmetic case, the cosmetic case is intended to be made of metal, but the cost is higher than that of synthetic resin, and the manufacturing process is complicated, making it difficult to manufacture the cosmetic case using a metal plate in the actual market.

In addition, since each metal plate is cut as much as a cosmetic case, various patterns and coating layers are formed, so that there are many processing steps and a long working time, and there is a problem that the manufacturing cost increases.

The present invention is to solve the above-described problems, while manufacturing a cosmetic case using a metal plate to form a pattern and / or coating layer on the entire cosmetic case, while forming the cosmetic case and the pattern and / or coating layer is not damaged while The purpose of the present invention is to provide a method for manufacturing a cosmetic case that can reduce the number of processing steps and reduce the working time and manufacturing cost.

In order to achieve the above object, a method of manufacturing a cosmetic case of the present invention includes a preparation step of preparing a metal plate; A processing step of forming a processing layer made of any one or more of a pattern or a coating layer on one surface of the metal plate; A protective film attaching step of attaching a protective film on one side of the metal plate on which the processing layer is formed; A placement step of placing the metal plate on the hollow die top such that one side of the metal plate with the protective film is facing downward and the other side of the metal plate is facing upward; A molding step in which the punch disposed on the upper portion of the die comes into contact with the metal plate and descends into the die to press the metal plate into a cup-shaped cosmetic case with a concave interior; Extraction step of extracting the cosmetic case from the die; made to include, but the punch is lowered while coming into contact with the other surface of the metal plate to which the protective film is not attached, the one side of the metal plate to which the protective film is attached is the It characterized in that the metal film is bent into a cup-shaped cosmetic case in which the inside is concave while the protective film is in contact with the inside of the die by the lowering of the punch.

The processing step includes a pattern step of etching a surface of the metal plate to form a pattern; It consists of; a coating step of forming a coating layer on the upper surface of the metal plate is a pattern is formed, the protective film is attached to the protective film is attached to the upper surface of the metal plate on which the coating layer is formed.

It comprises a; cutting step of cutting the excess portion present on the top of the pressure-molded cosmetic case.

A protective film removal step of removing the protective film from the cosmetic case after the extraction step; And a washing step of washing the cosmetic case from which the protective film is removed.

The processing layer is made of a coating layer formed on one surface of the metal plate, but the bonding force between the coating layer and the metal plate formed on the upper surface of the metal plate is stronger than the bonding force between the protective film and the coating layer attached to the upper portion of the coating layer. Upon removal of the protective film, the coating layer remains on the metal plate.

The metal plate is divided into a large-sized disc and a smaller-sized cutting plate than the original plate, and further comprises a blanking step of cutting the large-sized disc into a plurality of small-sized cutting plates. The steps, the processing step and the attaching step are performed before the blanking step to form the processing layer and the protective film on the entire large-sized disc, and in the blanking step, a plurality of the discs on which the processing layer and the protective film are formed as a whole are The cutting layer and the protective film are cut and formed on each cutting plate by cutting with a cutting plate, and the cosmetic case is press-molded by performing the placement step and the molding step with the cutting plate formed in the blanking step.

According to the manufacturing method of the cosmetic case of the present invention as described above has the following effects.

In the present invention, since the metal plate is press-molded after forming the processing layer (pattern and / or coating layer) on the metal plate, a pattern and / or coating layer may be formed on the entire cosmetic case.

In addition, since the protective film covers the metal plate, it is possible to prevent the pattern and / or coating layer formed on the metal plate from being damaged during pressure molding by punching.

In addition, the present invention attaches the processing layer (pattern, coating layer) and a protective film to a large-sized disc, and later cuts the original plate into a small-sized cutting plate, thereby reducing the number of processing steps and the working time due to this. And manufacturing cost.

Although the present embodiment and the drawings illustrate that both the patterning step (S2) and the coating step (S3) are included, the processing step may consist of only one of the patterning step (S2) or the coating step (S3).

The patterning step (S2) is a step of forming various patterns 11 by etching the entire surface of the metal plate, that is, the original plate 10, as shown in FIG. 2 (b).

In the patterning step (S2), a pattern 11 is formed on the original plate 10 through a hairline, buffing, sandblasting, or the like, and a pattern 11 is formed by using a roll press or etching, or a laser is used. By etching the original plate 10 to form a pattern (11).

That is, in the patterning step S2, grooves of various patterns 11 are formed by finely etching one surface of the original plate 10.

The pattern 11 is actually a groove shape, but in the drawing of the present embodiment, the pattern 11 is expressed as a single layer covering the groove.

The coating step (S3) is a step of forming a coating layer 12 on the entire surface of the entire surface of the disk 10, the pattern 11 is formed by the pattern step (S2) as shown in Figure 2 (c) to be.

In some cases, when the patterning step (S2) is absent, the coating step (S3) forms the coating layer 12 on the upper surface of the disc 10 without the pattern 11.

In the coating step (S3), a coating layer 12 is formed on the entire surface of the original plate 10 using various methods such as plating, vapor deposition (PVD), painting, anodizing, and coloring.

The pattern 11 formed on one surface of the original plate 10 by the coating step S3 is disposed under the coating layer 12 so that the pattern 11 is not directly exposed to the outside.

The protective film attaching step (S4) is a step of attaching the protective film 13 to the entire upper surface of one surface of the disk 10 on which the coating layer 12 is formed, as shown in FIG. 2 (d).

The protective film 13 is preferably made of a PVC material having a thickness of 0.05 ~ 0.3mm.

The protective film 13 is attached to one surface of the original plate 10 by an adhesive or the like.

By attaching the protective film 13 to the entire upper portion of the coating layer 12 as described above, the processing layer, that is, the pattern 11 and / or the coating layer 12 is protected without being damaged in a process described below.

In addition, the bonding force between the coating layer 12 and the original plate 10 formed on one surface of the metal plate is stronger than the bonding force between the protective film 13 and the coating layer 12 attached to the upper portion of the coating layer 12.

The blanking step (S5) is a step of cutting the large-sized disc 10 into a plurality of small-sized cutting plates 20, as shown in FIG. 2 (e).

The preparation step (S1), the patterning step (S2), the coating step (S3) and the attaching step are made before the blanking step (S5), the pattern (11), the coating layer (12) over the large disk (10) ) And the protective film 13 are formed.

In the blanking step (S5), each of the cutting plates 20 is cut by cutting the original plate 10 formed with the pattern 11, the coating layer 12, and the protective film 13 into a plurality of the cutting plates 20. In the pattern 11, the coating layer 12 and the protective film 13 is formed to be cut.

The process performed after the blanking step (S5) is performed with the cutting plate 20 having a small size formed in the blanking step (S5).

In the arrangement step (S6), as shown in Figure 3 (a), the protective film 13 is attached to a metal plate, that is, one side of the cutting plate 20 faces down and the other side of the cutting plate 20 faces the top. In the state of facing, it is a step of placing the cutting plate 20 on top of the hollow die 40.

That is, one surface of the cutting plate 20 to which the pattern 11, the coating layer 12, and the protective film 13 are attached is placed on the upper portion of the die 40 while facing downward.
