The inner surface of the thin film of polyethylene terephthalate by a laminated metal sheet of aluminum which is adhered a film of polyethylene terephthalate to compensate for this drawback film surface is pressed into a predetermined shape such that the inner surface Although the container which makes it the state which stuck is also known, since it is by cutting or roll processing as the cutting processing method of the opening part after a press in the conventional process, it says that the metal burr | flash will generate | occur | produce in the cut end. It was a thing.
[0005]
Next, in order to remove the burrs, a chamfering process was performed using a knife or other tool, or a tool such as a reamer. At that time, the film on the inner surface was damaged, and the film was made of aluminum from the cut surface. There is a disadvantage that it is easier to peel off than the plate material of the rubber plate, and instead of chamfering treatment, a method of curling the mouth and covering the cut surface is also known, but in that case the design can be done by curling It was a sacrifice.
[0006]
In view of the above-described conventional drawbacks, the present invention provides a storage member that constitutes a cosmetic storage container that is excellent in corrosion resistance and wear resistance such as oxidation and corrosion, and that does not sacrifice design, and a method for manufacturing and processing the same. The purpose is to do.
[0007]
[Means for Solving the Problems]

[0012]
In stamping 8 of the present invention as shown in FIG. 3, the pressing step 8 the die 9 to the plate 7 of the aluminum in which the film 5 of polyethylene terephthalate is adhered film 5 is the inner surface The lid 3 is pressed into a predetermined shape except for the cut end by drawing or the like with the punch 10.
[0013]
FIG. 4 shows a film cutting step 11 performed after the press working step 8.
This film cutting step 11 is formed on a rotating first inner roll 12 having a first inner roll rotary blade 13 inserted into the lid 3 pressed into a predetermined shape by the press working step 8, and on the outer surface thereof. Only the film 5 on the inner surface of the lid 3 is cut over the entire circumference by being sandwiched by a first outer roll 14 having a cylindrical pressing portion 15 that rotates in the opposite direction to the first inner roll 12.
[0014]
At that time, it is desirable that the first inner roll rotary blade 13 has a taper having a diameter that is enlarged with respect to the bottom direction of the lid 3, and the film 5 is cut so as to be sheared by the enlarged diameter part of the taper. Therefore, the inner surface of the lid 3 from the opening portion of the film cutting surface 25 may be processed to be slightly tapered.
[0015]
5 shows a metal cutting step 16, the film cutting step 11 slightly opening nearer film cutting surface 25 of the polyethylene terephthalate film 5 that has been cut by, for example 0.5mm~2mm about opening nearer A second inner roll 17 having a second inner roll rotary blade 18 inserted in the lid 3 and a second outer roll formed on the outer surface thereof and rotating in a direction opposite to the second inner roll 17. The film 5 and the metal lid body 4 are cut over the entire circumference by being sandwiched so as to be sheared by the second outer roll 19 having the rotary blade 20.
[0016]
At that time, since the second roll blade 17 including the second inner roll rotary blade 18 does not touch the film 5 behind the film cutting surface 25, the film 5 is not damaged.
[0017]
FIG. 6 shows a decorating process 21, and the lid body 4 that has finished the metal cutting process 16 is washed and degreased, and then decorated with a coating device such as a spray 22. In this way, the decorative layer 6 is formed on the outer peripheral surface of the lid body 4.
[0018]
The decorative layer 6 is not limited to painting, but may be printed, plated, anodized, or the like, and thus the lid 3 of the cosmetic container 2 is completed.
[0019]
Since the storage member constituted by such a processing method has the film cut surface 25 slightly behind the metal cut surface 26 at the mouth, even if the film 5 on the metal cut surface 26 is peeled off, the metal cut surface 26 and the film It is only between the cut surfaces 25, and the film 5 behind the film cut surfaces 25 does not peel off.
[0020]
