There is a so-called reversible hinge cap, which can open and close the lid with one touch, the lid does not get in the way during use,
And there is no fear of loss.

There is also known a double-tube structure cap that has an outer cylinder that is flush with the outer peripheral wall of the container when the cap is tightened and is located on the outside of the screw cylinder. Fashionability can be enhanced by making the operation easier and by making the cross-sectional shape of the outer cylinder non-circular such as elliptical or rectangular.

Further, as disclosed in Japanese Utility Model Laid-Open No. 62-161656, two members are formed by combining the above two to form a double-cylinder inverted hinge cap, in which the cap body and the rotating cover cap are colored and molded in different colors. The two-tone color reversal, which is configured by fitting them together, has a mechanism for preventing the removal of the rotating cover cap provided in the gap between the double cylinders on the connecting side of the rotating cover cap so as not to spoil the appearance. Hinge built-in caps are also known.

[Problems to be Solved by the Invention] However, in such a conventional two-tone color inversion hinge built-in cap, the fitting portion between the rotating cover cap and the cap body is limited to one place on the circumference of the cap. As a result, there is a problem that the operation is unstable due to a fluctuation due to an operation, and the cap upper surface becomes a single color when the rotating cover cap is opened, which makes the design monotonous.

The present invention has been made in view of the above circumstances, and an inversion hinge cap having a double cylinder structure can be configured by two members to form an interesting two-tone color.
Moreover, the fitting portion of these two members is stable, and the cap upper surface in the state in which the rotary cover cap is opened can be a two-tone color having a pattern different from that in the state in which the rotary cover cap is closed. It is an object of the present invention to provide a reversible hinge built-in cap that further enhances functionality and fashionability.

[Means for Solving the Problems] To solve this problem, an inversion hinge built-in cap of the present invention has a cap body integrally including an outer cylinder and a lower top plate portion, a rotating cover cap, and the rotating cover cap.
