Hereinafter, embodiments will be described with reference to the drawings. In the following description, elements having the same function and configuration are designated by a common reference numeral.

[1] Suitcase Manufacturing Method FIG. 1 shows a schematic view of a suitcase manufacturing method according to an embodiment of the present invention. FIG. 2 shows a flow chart of a suitcase manufacturing process according to an embodiment of the present invention. Hereinafter, a method for manufacturing a suitcase according to the present embodiment will be described with reference to FIGS. 1 and 2.

First, the mixed material A is prepared in the tank A (ST11A), and the mixed material B is prepared in the tank B (ST11B). Here, the mixing material A is a mixture of a polycarbonate resin (PC: polycarbonate) 21, a dye agent 22, and an antibacterial agent 23. In the mixing material B, the polycarbonate resin 21 and the additive (for example, a material having a high burst prevention effect) 25 are mixed at a ratio of, for example, 98.5% and 1.5%. The method for producing the mixed material A will be described in detail later.

Next, the temperature adjustment of the heat treatment apparatus 1A for the tank A and the heat treatment apparatus 1B for the tank B is started.

When the heat treatment apparatus 1A reaches a predetermined set temperature (for example, about 250 ° C. to 265 ° C.), the mixed material A sucked up from the tank A is melted at a high temperature, and the heat treatment apparatus 1A becomes a jelly. Extruded. As a result, the A layer 11 made of the mixed material A is formed (ST12A).

Similarly, when the heat treatment apparatus 1B reaches a predetermined set temperature (for example, about 250 ° C.), the mixed material B sucked up from the tank B is melted at a high temperature, and the heat treatment apparatus 1B is in a jelly-like state. Extruded. As a result, the B layer 12 made of the mixed material B is formed (ST12B).

Next, in the welding device 2, the A layer 11 and the B layer 12 are welded to form one laminated plate 13 (ST13). The laminated plate 13 is wound by a roller 3 to complete the antibacterial laminated plate 13. Then, the laminated plate 13 is cut by an automatic cutting machine (not shown) according to each product size. Then, the body of the suitcase is manufactured using the cut laminated plate 13 (ST14).

In addition, for example, at the time of welding of ST13, the riding condition of the dye of the laminated board 13 may be adjusted. Further, when the dye of the laminated plate 13 becomes stable, the temperature of the roller 3 may be set to a high temperature to remove discoloration and moisture.

[2] Manufacturing Method of Mixed Material A FIG. 3 shows a schematic view of a manufacturing method of mixed material A according to an embodiment of the present invention. FIG. 4 shows a flow chart of a manufacturing process of the mixed material A according to the embodiment of the present invention. Hereinafter, a method for producing the mixed material A according to the present embodiment will be described with reference to FIGS. 3 and 4.

First, as the mixing material A of the tank A, the polycarbonate resin 21, the pigment agent 22, and the antibacterial agent 23 (23a, 23b) are used. Each material of the mixed material A is, for example, in a particle state.
Here, the ratio of each material of the mixed material A is, for example, preferably 88 to 85% for the polycarbonate resin 21, 9 to 5% for the dyeing agent 22, and 3 to 10% for the antibacterial agent 23. This is because if the ratio of the antibacterial agent 23 is 3% or more, it has an antibacterial effect, and if it exceeds 10%, the dye does not appear properly. Specifically, for example, the polycarbonate resin 21 is 87%, the pigment agent 22 is 8%, and the antibacterial agent 23 is 5%.

Further, the antibacterial agent 23 may be divided into two antibacterial agents 23a and 23b. In this case, the antibacterial agent 23a may be used as the mixed material 24 mixed with the dyeing agent 22.

The mixed material A using such a polycarbonate resin 21, a dye agent 22, and an antibacterial agent 23 is produced, for example, as follows.
First, 40% of the polycarbonate resin 21 is charged into the tank A with respect to the entire polycarbonate resin 21.
Next, all of the mixed material 24 in which the dyeing agent 22 and the antibacterial agent 23a are mixed is charged into the tank A and mixed and heated. Here, the mixed material 24 is manufactured by mixing the dyeing agent 22 and the antibacterial agent 23a in advance.

Next, 40% of the polycarbonate resin 21 with respect to the entire polycarbonate resin 21 is charged into the tank A and mixed and heated.
Next, the antibacterial agent 23b is divided into a plurality of times, charged into the tank A, and mixed and heated. For example, 30%, 20%, 20%, and 30% of the antibacterial agent 23a are sequentially added to the tank A with respect to the entire antibacterial agent 23b. In this way, by adding the antibacterial agent 23b in a plurality of times, the antibacterial agent 23b can be evenly mixed with the mixing material A without being solidified in one place.

Finally, 20% of the polycarbonate resin 21 with respect to the entire polycarbonate resin 21 is charged into the tank A and mixed and heated. As a result, the mixed material A is completed.

The mixed material 24 of the dye agent 22 and the antibacterial agent 23a can be added in a plurality of times. Further, the mixed material 24 may be added at the end of the manufacturing process.

Can be retained for a long period of time.

[4] Laminated Plate As shown in FIG. 1, the laminated plate 13 of the present embodiment is composed of two layers, an A layer 11 and a B layer 12. Here, the thicknesses of the A layer 11 and the B layer 12 with respect to the laminated plate 13 may be different or the same. In the former case, for example, the A layer 11 is about 40% and the B layer 12 is about 60%. Further, in the laminated plate 13, it is desirable that the layer A 11 is located outside the body of the suitcase.

In this figure, the laminated board 13 is composed of two layers, A layer 11 and B layer 12, but is not limited to this, and may be configured with three or more layers.
For example, as shown in FIG. 5, the laminated plate 13 may be a three-layer structure in which the B layer 12 is sandwiched between the two A layers 11 and 14. In this case, the same material may be used for the layers A 11 and 14, or different materials may be used. When the A layer 11 is located outside the body in such three layers, for example, the thickness of the A layer 11, the B layer 12 and the A layer 14 with respect to the laminated plate 13 is, for example, 30% for the A layer 11 and B. The layer 12 may be about 60% and the layer A 14 may be about 10%.
Further, when the laminated plate 13 has four layers, one transparent sheet may be added to the surface of the A layer 11 having the structure of FIG.

In the laminated board 13, it is desirable to use a new material for the polycarbonate resin 21 constituting the A layer 11. However, the polycarbonate resin constituting the B layer 12 may be a new material or a recycled material. As a result, the cost can be reduced.

It is also possible to mix the antibacterial agent 23 with the mixing material B constituting the B layer 12. Thereby, the antibacterial effect of the laminated board 13 can be further improved.

[5] Effect The body of the suitcase according to the present embodiment is formed by using a laminated plate 13 mixed with an antibacterial agent 23. The antibacterial effect of the laminated board 13 was inspected by the standard technical service (Shanghai) Co., Ltd., which is a Chinese inspection organization. As a result, it was evaluated that the antibacterial rate by the laminated board 13 was 99.9%.

Further, the laminated plate 13 used for the body of the suitcase is composed of a plurality of layers (A layer 11 and B layer 12). This makes it possible to improve the strength of the body of the suitcase.
When the laminated plate 13 is used for the body of a suitcase, the body may be manufactured so that the A layer 11 is on the outside of the suitcase and the B layer 12 is on the inside of the suitcase. This makes it possible to enhance the antibacterial effect on the outside of the suitcase, which is easily affected by bacteria.

Although the embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention.
