FIG. 3 is a flow chart for explaining a method of manufacturing a cosmetic container according to an embodiment of the present invention, FIG. 4 is a flowchart for illustrating a step of preparing a content container in a method of manufacturing a cosmetic container according to an embodiment of the present invention, FIG. 5 is a view showing a transparent part and a colored part prepared in the method of manufacturing a cosmetic container according to an embodiment of the present invention.

Referring to FIG. 3, a method of manufacturing a cosmetic container according to an embodiment of the present invention includes the steps of preparing a content container by combining a colored part made of a homogeneous material with a transparent part (S10), storing the content container in an outer container mold (S20), and a step (S30) of injecting an outer container into the content container.

In step S10, the colored container 1121 made of the same kind of material and the transparent part 1122 are combined to prepare the content container 112. [ Specifically, referring to FIG. 4, the step of preparing the content container 112 of step S10 may include steps S11 to S13.

First, in step S11, a space is formed to accommodate cosmetics, and a transparent part 1122 made transparent so as to expose the color of cosmetics can be prepared. The transparent portion 1122 may be formed by manufacturing a transparent portion 1122 through a plastic injection method and the shape of the transparent portion 1122 may be various shapes such as a cylindrical shape or a polygonal shape, Is possible. The transparent portion 1122 can be formed on the inner side of the lower portion opposite to the entrance 1131 of the container body 110. Since the transparent portion 1122 is made of a transparent material, the paint color of the cosmetic can be exposed as it is, The interior is exposed and the remaining amount of cosmetics can be confirmed.

Here, the transparent portion 1122 may be integrated with the outer container 111 through a step S30 of injecting the outer container described later. The transparent portion 1122 and the outer container 111 are integrated to penetrate the outer container 111 to expose the inner color of the transparent portion 1122. The transparent portion 1122 is integrated with the outer container 111 The interior shape of the transparent portion 1122 may be formed without deforming so that the interior shape of the final cosmetic container 100 in which the cosmetic is received in the container body 110 can be achieved. Since the transparent portion 1122 is manufactured through the plastic injection method, the capacity and shape of the container body 110 can be variously implemented.

In step S12, a colored portion 1121 having a space communicated with the transparent portion 1122 may be prepared. Step S12 of preparing the colored portion 1121 can be performed by manufacturing the colored portion 1121 through the plastic injection method in the same or similar manner as in Step S11. The step S12 may be performed in accordance with the shape of the transparent portion 1122, . The colored portion 1121 is integrated with the outer container 111 through the process described below in the same manner as or similar to the transparent portion 1122. However, the colored portion 1121 may be colored differently from the outer container 111, The color of the colored portion 1121 can be exposed as it is.

Step S13 includes a step (S13) of assembling the transparent part 1122 and the colored part 1121. The transparent portion 1122 and the colored portion 1121 may be assembled through a simple fitting process to form the container 112. For example, the end where the transparent portion 1122 and the colored portion 1121 face each other (See Fig. 5). For this purpose, the transparent portion 1122 may be stepped on the inner side of the lower end so that the outer side of the transparent portion 1122 forms a step difference, and the colored portion 1121 is inserted into the transparent portion 1122. As described above, the present embodiment can reduce the manufacturing cost by assembling through a simple fitting process without performing a process with a relatively high unit price such as a deposition process. Of course, the transparent portion 1122 and the colored portion 1121 may be simply abutted to each other without direct bonding, and may be bonded only through the outer container 111 injection mentioned in Step S30.

The melting point of the inner container 112 may be higher than or at least equal to the melting point of the outer container 111. The outer container 111 preferably has a melting point higher than or equal to the melting point of the outer container 111, The melting point of the content container 112 is higher than the melting point of the container 112 so that the outer container 111 can be fused without deforming the container 112 when the container 111 is formed.

The transparent portion 1122 and the colored portion 1121 are made of the same material as the polycarbonate, It is possible to maintain the injection uniformly with the same melting point.

Also, in this embodiment, the colored portion 1121 may have a cross-sectional area smaller than or equal to the transparent portion 1122 at a portion where the colored portion 1121 is joined to the transparent portion 1122. [ When the outer container material is introduced from the transparent portion 1122 toward the colored portion 1121 after the container 112 is accommodated in the outer container mold, 1121 in the process of flowing.

If the cross-sectional area of the colored portion 1121 is larger than the cross-sectional area of the transparent portion 1122, a step is created in which the cross-sectional area of the colored portion 1121 and the transparent portion 1122 are expanded, The flow of the outer container material is caught, so that the injection pressure is generated and deformation of the container 112 may occur. However, in the present embodiment, the cross-sectional area of the colored portion 1121 is limited so that a step having a reduced cross-sectional area is formed at the engagement portion of the colored portion 1121 and the transparent portion 1122, Can be effectively prevented.

In the step S10, the colored portion 1121 and the transparent portion 1122 are combined to prepare the content container 112. In the preparation steps S11 and S12 of the colored portion 1121 and the transparent portion 1122, Can be reversed. That is, after preparing the transparent portion 1122 of the step S12 and then preparing the colored portion 1121 of the step S11, it is possible to perform the step of assembling the transparent portion 1122 and the colored portion 1121 of the step S13.

In step S20, the content container 112 is accommodated in an outer container mold (not shown).

For example, when the transparent portion 1122 is provided at the lower end of the container body 110 and the colored portion 1121 is provided at the upper end where the entrance 1131 is formed, the colored portion 1121 may include a transparent portion 1122, Or may have a smaller cross-sectional area than the transparent portion 1122. [

The colored container 1121 can be inserted into the outer container mold first than the transparent container 1122 and the colored container 1121 can be inserted into the outer container mold 1122 in a state where the colored portion 1121 and the transparent portion 1122 are stacked in order. The transparent portion 1122 may be received first.

The inner surface of the transparent portion 1122 and the inner surface of the colored portion 1121 may be the same or different from each other. The shape of the outer portion of the inner container 112 and the outer shape of the inner portion of the container 112 may be the same Such as forming a polygon, or forming a different shape such as a circle and a polygon.

In step S30, the outer container 111 is injected into the container 112. [

The outer container 111 may be manufactured through the plastic injection method in the same or similar manner to the inner container 112. The outer container 111 may be formed in a state in which the container 112 is accommodated in the outer container mold, 112) and the outer container mold by injecting the raw material.

Here, the PETG material of the outer container 111 is injected into the outer container mold, and the outer container material is colored from the transparent portion 1122 through a hole (not shown) of the outer container metal mold provided on the transparent portion 1122 side. And may be introduced in the direction of the portion 1121.

PETG material, which is a raw material of the outer container 111, is melted and injected into the outer container mold, and then the outer container 111 is formed while the material is solidified and can be combined with the inner container 112. The melting point of the PETG material of the outer container 111 is lower than the melting point of the polycarbonate of the inner container 112 so that when the outer container 111 is injected onto the outer surface of the container 112, It is possible to prevent deformation due to the injection temperature while the container 111 is integrated.

In this embodiment, by making the cross-sectional area of the colored portion 1121 located on the opposite side of the portion of the container 112 into which the raw material of the outer container 111 is drawn to be narrower or equal to the cross-sectional area of the transparent portion 1122, It is possible to prevent deformation due to the injection pressure when the container 111 is injected. Since this is the same as described above, a detailed description will be omitted.

The outer container 111 may have a transparent hue as the transparent portion 1122, so that the outer container 111 and the transparent portion 1122 may be integrally formed as one body. However, the colored portion 1121 may be hued through the outer container 111 to be hued.

As described above, the present invention can reduce the manufacturing cost by assembling through a simple fitting process by omitting a process having a relatively high unit cost such as a deposition process or a metal cylinder covering process.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification and the modification are possible.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
