  Next, the manufacturing method of the metal container 1 which concerns on embodiment of this invention is demonstrated using FIGS.

The manufacturing method of the metal container 1 is performed using a cutting machine.
As shown in FIG. 1, first, in the method for manufacturing the metal container 1, a cutting process is performed on the metal lump (ingot) 10 with a cutting machine (a cutting tool of the cutting machine) (step S <b> 1).

Here, the metal lump 10 indicates a lump of a metal material such as SUS (stainless steel), copper, silver, or tin. Below, the metal lump 10 is demonstrated as what consists of a SUS raw material.
The metal container 1 refers to a metal container used in eating and drinking such as a cup, various glasses (tumbler glass, wine glass, cocktail glass), or tableware.

As shown in FIG. 2, the step of machining the metal lump 10 (step S1) includes the step of forming the inner surface 1a of the metal container 1 (step S11) and the outer surface 1b of the metal container 1. And a process (step S12).
As shown in FIG. 3, in the step of cutting the metal lump 10 (step S1), first, the step of forming the inner surface 1a of the metal container 1 is performed (step S11).
After performing the process (step S11) which shape | molds the inner surface 1a of the said metal containers 1, it transfers to step S12.

In the step of machining the metal lump 10 (step S1), next, the step of forming the outer surface 1b of the metal container 1 is performed (step S12). The step of forming the outer surface 1b of the metal container 1 (step S12) is performed after the step of forming the inner surface 1a of the metal container 1 (step S1).
At this time, as shown in FIG. 4, the lid member 3 is filled so that the filler 2 is filled into the inside (the portion corresponding to the inside) of the metal container 1 and the opening 1 c of the metal container 1 is covered from the outside. The metal lump 10 is held by sandwiching the outside of the lid member 3 and the portion corresponding to the bottom of the metal container 1 with a predetermined holder (not shown).
Thus, the outer surface 1b of the metal container 1 is formed in a state where the metal lump 10 is held.
Here, the filler 2 can be filled inside the metal container 1 and can be removed from the inside of the metal container 1 after the step (step S12) of forming the outer surface 1b of the genus container. It shows something. Examples of the filler 2 include sand, granular materials such as Meriken powder, ice, and resin.

  As described above, the step of machining the metal lump 10 (step S1) is performed.

As mentioned above, the manufacturing method of the metal container 1 performs the process which cuts the metal lump 10 (step S1). In the manufacturing method of the metal container 1, the thickness of the metal container 1 can be set to about 0.1 mm to 0.5 mm.
Therefore, according to the manufacturing method of the metal container 1, it can be made thinner than the metal container shape | molded by casting, The metal container of thickness (thin thickness) equivalent to a glass container, can do.
Moreover, as shown in FIG. 4 or FIG. 5, according to the manufacturing method of the metal container 1, the shape (a tatami-shaped mold, which has a larger inner diameter than the mouth edge (the upper opening 1c) of the metal container 1 is provided. Alternatively, it can be molded in a tulip type container.
Further, in the drawing process, it is difficult to form a metal container from a single metal plate, so that it is difficult to form a different thickness depending on the part. According to the manufacturing method of the metal container 1, FIG. As shown, the metal container 1 having a different thickness can be formed depending on the part. For example, the body portion of the metal container 1 can be formed thin and the bottom portion can be formed thick.

Then, by making the cuts 1c that gradually become deeper as the thickness of the metal container 1 increases, for example, a face pattern can be provided on the outer surface 1b.

  As shown in FIG. 1, after performing the process (step S2) of giving the single or several linear cut 1c to the outer surface 1b of the metal container 1, it transfers to step S3.

Next, a step of applying a temper collar 1d to the outer surface 1b of the metal container 1 is performed (step S3).
At this time, the temper collar 1d is applied to the outer surface 1b (a part or the whole of the outer surface 1b) of the metal container 1 by heating a part or the whole of the outer surface 1b of the metal container 1 at 300 to 400 ° C.
