In this embodiment, the hinge portion 50 is configured by a pair of wall portions 23 a and 23 b, a convex portion 34 , a first pin 61 and a second pin 62 . When the lid 30 rotates about the rotation axis O2 with respect to the container body 20, the first pin 61 and the second pin 62 move relative to at least one of the pair of walls 23a and 23b and the projection 34. rotate to In this embodiment, the first pin 61 and the second pin 62 are integrated with the convex portion 34 (the lid 30) to rotate around the rotation axis O2 when the lid 30 rotates about the rotation axis O2 with respect to the container body 20. It rotates around and rotates relative to the pair of walls 23a and 23b (container body 20). As a result, when the lid 30 rotates with respect to the container body 20, the outer peripheral surface of the first pin 61 and the outer peripheral surface of the second pin 62 are slide respectively.

The inner container 40 is installed inside the container main body 20, as shown in FIG. The inner container 40 is a flat cylindrical container arranged coaxially with the container axis O1. The inner container 40 opens upward. Contents C are accommodated inside the inner container 40 . The content C is formed by hardening powder, for example. The content C is, for example, cosmetics such as foundation. For example, a puff P is placed on the upper side of the content C. As shown in FIG. The content C may be liquid foundation or powder. In these cases, an inner lid is provided to close the upper opening of the inner container 40 . In particular, when the content C is a liquid foundation, an inner lid is provided that can hermetically close the interior of the inner container 40 .

According to this embodiment, the opening angle θ of the lid 30 with respect to the container body 20 can be maintained at an arbitrary angle. A detailed description will be given below. The opening angle θ is a rotation angle when the lid 30 rotates about the rotation axis O2 in the direction in which the lid 30 opens from the closed state indicated by the solid line in FIG. 2 . That is, the opening angle θ is 0° when the lid body 30 is closed as indicated by the solid line in FIG. 2 .

Therefore, the first pin 61 and the second pin 62 can be more firmly fitted into the body-side holes 25 a and 25 b of the container body 20 . As a result, even if the opening angle θ of the lid 30 with respect to the container body 20 is set to an arbitrary angle, the first pin 61 and the second pin 62 resist the weight of the lid 30 and rotate relative to the container body 20 . Relative rotation around O2 can be suppressed.

On the other hand, according to the present embodiment, in each of the first pin 61 and the second pin 62, the portions of the first pin 61 and the second pin 62 that are fitted into the lid-side holes 35a and 35b on the side formed in the lid 30 are rotated in the rotation axis direction. Dimensions L1b and L2b are 7.0 mm or less. Therefore, the first pin 61 and the second pin 62 are less likely to receive force from the lid 30 , and the rotation of the first pin 61 and the second pin 62 together with the lid 30 can be suppressed. This makes it easy to maintain the lid 30 at an arbitrary opening angle θ.

As described above, according to the present embodiment, by adjusting the lengths of the first pin 61 and the second pin 62 that are fitted into the body-side holes 25a, 25b, 35a, and 35b, the opening of the lid 30 can be adjusted. The angle θ can be maintained at any angle. Therefore, according to this embodiment, the opening angle .theta.

Further, according to the present embodiment, in each of the first pin 61 and the second pin 62, the dimension L1a in the rotation axis direction of the portion fitted into the body-side holes 25a and 25b formed in the container body 20 is , L2a are greater than or equal to 5.5 mm. Therefore, the first pin 61 and the second pin 62 can be more firmly fitted into the body-side holes 25 a and 25 b of the container body 20 . Thereby, it is possible to further suppress relative rotation about the rotation axis O<b>2 with respect to the container body 20 .

Further, according to the present embodiment, in each of the first pin 61 and the second pin 62, the dimension L1b in the direction of the rotation axis of the portions fitted into the lid-side holes 35a and 35b on the side formed in the lid 30 is , L2b are equal to or larger than 4.2 mm and equal to or smaller than 6.2 mm. As a result, the first pin 61 and the second pin 62 are less likely to receive force from the lid body 30 . In addition, it is possible to prevent the length of the first pin 61 and the second pin 62 fitted to the lid 30 from becoming too small, and the lid 30 rotates relative to the first pin 61 and the second pin 62 by its own weight. can be suppressed, and the lid body 30 can be more easily maintained at an arbitrary opening angle θ.

The dimensions L1a, L1b of the first pin 61 and the dimensions L2a, L2b of the second pin 62 may be different from each other. The outer diameter of the first pin 61 and the outer diameter of the second pin 62 may be different from each other. In each pin, the interference for the body-side holes 25a and 25b on the container body 20 side and the interference for the lid-side holes 35a and 35b on the lid 30 side may be different from each other. The first pin 61 and the second pin 62 may be connected to each other and integrated.
Further, in the above-described embodiment, the wall portions 23a and 23b are provided on the container body 20, and the convex portion 34 is provided on the lid member 30, but the present invention is not limited to this. The wall may be provided on the lid, and the projection may be provided on the container body.

Example 1 to Example 3 and Comparative Example 1 to Comparative Example 3 were compared to verify the effects of the present invention. In each example and each comparative example, each dimension of the first pin and the second pin was as shown in Table 1. Also, in each example and each comparative example, the outer diameter of the first pin and the outer diameter of the second pin were set to 1.59 mm. The first pin and the second pin were made of stainless steel (SUS). The container main body and lid were made of ABS resin. The mass of the lid body was 50 g. Each pin was press-fitted into each hole, and the interference between each pin and each hole was 0.09 mm.

First, for each example and each comparative example, the lid body was changed from a state in which the opening angle θ was 0° (a state in which the lid body was closed) to a state in which the opening angle θ was 180° (a state in which the lid body was completely open). , and then the opening/closing operation was performed a predetermined number of times to return the opening angle θ to 0°. After that, the lid was opened to a predetermined opening angle θ, and it was confirmed whether or not the predetermined opening angle θ could be maintained. At this time, if the predetermined opening angle θ can be maintained, it can be considered that the state of the predetermined opening angle θ was always maintained in the predetermined number of times of opening and closing operations performed at the beginning. assumed to be maintainable.

The test as to whether or not the predetermined opening angle θ can be maintained was performed after the lid was opened and closed 30 times. I went after times. This was repeated, and the number of times the opening angle θ could be maintained was measured for each example and each comparative example. For example, if the opening angle θ can be maintained after the lid is opened and closed 30 times, and if the opening angle θ can be maintained after the lid is opened and closed 20 times, then at least 50 times, It is assumed that the opening angle θ can be maintained. The predetermined opening angle θ was 30° and 120°. Table 1 shows the results.

As shown in Table 1, in Examples 1 to 3, when the opening angle θ is 30°, the opening angle θ can be maintained 100 times or more, and when the opening angle θ is 120°, It was confirmed that the opening angle θ could be maintained 30 times or more. On the other hand, in Comparative Examples 1 to 3, it was confirmed that the opening angle θ could not be maintained when the opening angle θ was 120°. In addition, when the opening angle θ is 30°, although the opening angle θ can be maintained, the number of times it can be maintained is 50 times or less, and the number of times until the opening angle θ can no longer be maintained is smaller than in each example. was confirmed.

In Comparative Examples 1 and 2, since the dimensions L1a and L2a in the rotation axis direction of the portions fitted into the holes formed in the container body are smaller than 5.0 mm, the pins are not fitted into the holes of the container body. It is considered that the joint was relatively weak and the opening angle θ could not be maintained at 120°. On the other hand, in Comparative Example 3, since the dimensions L1b and L2b in the rotation axis direction of the portions fitted in the holes formed in the lid are larger than 7.0 mm, each pin receives force from each lid. It is conceivable that each pin was easily rotated together with the lid, and the opening angle θ could not be maintained at 120°.

From the above, the dimensions L1a and L2a of the portions fitted in the holes formed in the container body in the direction of the rotation axis are set to 5.0 mm or more, and the holes fitted in the holes formed in the lid are set to 5.0 mm or more. It was confirmed that the opening angle of the lid can be maintained at an arbitrary angle by setting the dimensions L1b and L2b of the portions in the direction of the rotation axis to 7.0 mm or less. Moreover, according to Examples 1 to 3, it was confirmed that the number of times the predetermined opening angle θ can be maintained can be increased compared to Comparative Examples 1 to 3.
