BACKGROUND ART Conventionally, a container body such as a cosmetic container is one in which a thin metal cup-shaped body whose outer surface is subjected to a decoration treatment is fitted to a synthetic resin container body constituent member including a lid member and a container member. It was used a lot. However, as means for fitting and holding, there have been means such as press fitting, undercut engagement, and adhesive bonding.

[Problems to be solved by the invention] However, in the press-fitting and fitting means, the fitting strength remarkably differs due to dimensional variation and temperature change, and the container body constituent member and the cup-shaped body may come off during use. . Further, in the undercut engagement fitting means, rattling may occur between the container body constituting member and the cup-shaped body due to dimensional variation and temperature change. Further, the adhesive bonding means has a problem that not only the cost is greatly increased, but also the adhesive is attached to the outer surface of the cup-shaped body.

When the cup-shaped body is made of thin metal and the container body constituent member is made of synthetic resin, when the cup-shaped body is press-fitted into the container body constituent member, the burr generated on the inner surface of the lower end of the cup-shaped body causes It was necessary to chamfer the inner surface of the lower end of the cup-shaped body so that the side wall was not scraped.

[Means for solving the problem]

The container body constituting member 2 having the abutting portion 5 on the side wall thereof and the annular groove 8 formed on the side wall of the crease of the abutting portion 5 to form the abutting step portion 9, and the container body constituting member 2 are covered. A curl portion 11 which is fitted and formed of a thin metal whose outer surface is decorated and which is inserted into the annular groove 8 at the opening end 10 and engages between the contact step portion 9 and the contact portion 5 is provided. The curled portion 11 has a cup-shaped body 3 in which the open end 10 is curled in a somewhat trumpet shape, and the cup-shaped body 3 is fitted to the container body constituting member 2 to open the open end.
After the abutting portion 10 is brought into contact with the abutting portion 5, the opening end 10 is bent and curled along the abutting portion 5 of the container body constituting member 2 and the annular groove 8 by pressing the cup-shaped body 3. The shape.

[Action]

The thin metal cup-shaped body 3 is in a state in which the lower end and the tip end of the curl portion 11 are sandwiched between the contact portion 5 and the contact step portion 9 of the container body constituent member 2, and the cup-shaped body 3 and the container 3 The body component 2 is firmly fitted and fixed. Also, this curl portion 11
Since it is formed between the cup-shaped body 3 and the container body constituting member 2, it cannot be seen from the outside. In addition, a gap can be left between the cup-shaped body 3 and the container body constituting member 2, which also has a heat insulating function.

The curl portion 11 is formed by fitting the cup-shaped body 3 in which the opening end 10 is curled into a slightly trumpet shape into the container body component member 2 and bringing the opening end 10 into contact with the contact portion 5, By pressing the body 3, the contact portion 5 and the annular groove 8 of the container body constituting member 2
The open end 10 is bent and curled along the line.

〔Example〕

A first embodiment will be described with reference to FIGS. 1 to 4. The lid 1 is composed of a container body constituting member 2 which is an inner lid made of synthetic resin, and a cup-shaped body 3 which is an outer lid made of a thin metal which is fitted on the inner lid.

The cup-shaped body 3 is formed by forming a thin metal into a cup shape, and the outer surface thereof is subjected to a decoration treatment. The entire circumference of the open end 10 of the cup-shaped body 3 is narrowed inward in a trumpet shape.

The container body constituting member 2 has a screw 4 screwed on an inner wall thereof to be screwed into a body (not shown) to be fitted. Further, at the lower end of the outer wall of the container body constituting member 2, there is provided a brim-shaped contact portion 5 with which the open end 10 of the cup-shaped body 3 contacts when the cup-shaped body 3 is fitted. An annular groove 8 is provided around the outer wall slightly above the abutting portion 5 to form an abutting step portion 9 in the annular groove 8.

Then, the cup-shaped body 3 in a state where the opening end 10 is narrowed inward is fitted to the container body constituting member 2, and the opening end 10 is brought into contact with the contact portion 5.
Contact. In this state, when the upper surface of the cup-shaped body 3 is pressed from above, the opening end 10 is constricted inward, so that it bends inward along the contact portion 5 and the annular groove 8, and the tip portion is It abuts on the abutting stepped portion 9 of the container body constituting member 2.
This becomes the curl portion 11. That is, the cup-shaped body 3 is in a state in which the lower end and the tip of the curl portion 11 are sandwiched between the contact portion 5 and the contact step portion 9 of the container body constituting member 2, and the cup-shaped body 3
The container body component 2 is fixed so as not to fall off.

In addition, a concave R-shaped guide groove 6 may be provided on the upper surface of the contact portion 5,
The rotation stopping ribs 7 may be provided so as to project radially. When a concave R-shaped guide groove 6 is provided on the upper surface of the contact portion 5, the open end 10 of the cup-shaped body 3 is bent by the curved surface of the guide groove 6, and the tip end portion of the container body constituent member 2 is in contact with the contact step. It serves as a guide for contacting the portion 9. When the lid 1 has a cylindrical shape, the contact portion 5
If plural anti-rotation ribs 7 are radially provided on the upper surface of the container, not only the sliding of the opening end 10 at the time of molding the curl portion 11 is improved but also the anti-rotation of the container body constituting member 2 and the cup-shaped body 3 is prevented. become. Further, if the cup-shaped body 3 is constructed by using a laminated plate in which a synthetic resin sheet 12 is laminated on the outer surface, the rotation preventing rib 7 bites into the synthetic resin sheet 12 and the rotation preventing is further strengthened.

As the embodiment of the present invention, the lid 1 to be fitted on the container has been described. The structure of the lid 1 is such that the inner container 14 which is the container body constituent member 2 made of synthetic resin such as the container 13 is made of thin metal. Cup-shaped body 3
It is possible to carry out the invention by mounting it on a container body having the outer unit 15 fitted therein, and an embodiment thereof is shown in FIGS. 5 to 9.

[Effect of device]

As described above, according to the present invention, the curled portion 11 is formed between the cup-shaped body 3 and the container body constituting member 2 by fitting the cup-shaped body 3 into the container body constituting member 2 and pressing from above. ,
Since the cup-shaped body 3 and the container body constituting member 2 are engaged and held by the curl portion 11, as compared with the case where the press-fitting and undercut engaging means are used, the cup-shaped body 3 and the container body-constituting member 2 are made stronger irrespective of ambient temperature and dimensional error. It can be fitted without slap.

Further, since the cup-shaped body 3 is curled at the opening end 10 and fitted into the container body constituting member 2, the container body constituting member 2 is not scraped and chamfering is unnecessary. Then, the cup-shaped body 3 is provided with a synthetic resin sheet on the metal surface.
When molded from a laminated plate in which 12 is laminated, the end surface of the synthetic resin sheet 12 is the cup-shaped body 3 and the container body constituent member 2
It also has the effect of preventing the laminated synthetic resin sheet 12 from being peeled off by being caught in between. Further, a gap can be provided between the cup-shaped body 3 and the container body constituting member 2, and the heat insulation effect of the container body can be improved by the gap.
