[Rotating part (braking part, sliding contact part, holding part)]
Here, functions of the braking portion 51, the sliding contact portion 52, and the holding portion 53 of the turning portion 50 of the household thin paper storage container 100 of the present embodiment will be described.
The rotating portion 50 is composed of the container hinge portion 11 and the lid hinge portion 21 .
As shown in FIGS. 2, 4, 5, and 6, the container hinge portion 11 is provided with a braking portion 51 and a holding portion 53, and the lid hinge portion 21 is provided with the lid body 20 and the container body. A sliding contact portion 52 is provided that comes into sliding contact with the braking portion 51 when rotating in a direction away from 10 .

The braking portion 51 is a protruding piece provided to extend along the rotation direction of the lid body 20. When the braking portion 51 is viewed from the side, as shown in FIG. has a substantially circular arc shape with different heights (thicknesses).
Specifically, as shown in FIGS. 6A to 6D, the braking portion 51 causes the sliding contact portion 52 to brake as the lid body 20 rotates away from the container body 10. The braking portion 51 is formed so that the height of the braking portion 51 is gradually higher on the end point side than on the starting point side where it slides on the portion 51 , one end side (starting point side) is relatively low, and the other end side (end point side) is relatively low. ) is relatively high.

It is preferable that the braking portion 51 formed on the surface of the container hinge portion 11 is formed in a substantially arcuate shape with a central angle of 50° to 90°, for example.
If the central angle of the braking portion 51 is within the above range, the sliding contact portion 52 is preferably brought into sliding contact with the braking portion 51, and the force of rotation of the lid body 20 can be suppressed.
On the other hand, if the braking portion 51 has a central angle of less than 50°, the area where the sliding contact portion 52 slides is short, and the force of rotation of the lid body 20 may not be sufficiently suppressed.
If the central angle of the braking portion 51 is 90°, the force of rotation of the lid body 20 can be well suppressed, and the area of the braking portion 51 does not need to be widened any further. The central angle was within the above range.

Further, for example, the height of one end side (start point side) of the braking portion 51 is preferably 0.05 mm to 0.15 mm from the surface of the container hinge portion 11, and the other end side (end point side) of the braking portion 51 is preferably 0.05 mm to 0.15 mm. is preferably 0.2 mm to 1.0 mm from the surface of the container hinge portion 11 .
If the height of the braking portion 51 is within the above range, the sliding contact portion 52 is preferably brought into sliding contact with the braking portion 51, and the force of rotation of the lid body 20 can be suppressed.
On the other hand, if the height of the braking portion 51 is below the above range, the force of rotation of the lid 20 may not be sufficiently suppressed. Further, if the height of the braking portion 51 exceeds the above range, the lid 20 may not fully open and the rotation may stop.

Then, when the disengagement member 14 and the clamping portion 12 of the household thin paper storage container 100 are clamped to release the engagement between the locking portion 23 and the engaging portion 13, the biasing force of the biasing member 30 pushes up. The lid body 20 is rotated in a direction away from the container body 10 .
When the lid 20 is thus rotated in the direction away from the container body 10, as shown in FIGS. It comes into sliding contact with the braking portion 51 on the side of the main body 10 (container hinge portion 11).
The braking portion 51 with which the sliding contact portion 52 slides is formed so that the end point side of the sliding contact is higher than the starting point side of the sliding contact, so the sliding contact portion 52 rotates toward the end point side of the braking portion 51 . As the sliding contact portion 52 and the braking portion 51 come into pressure contact with each other, the frictional force between the sliding contact portion 52 and the braking portion 51 gradually increases, so that a brake is applied to suppress the turning force of the lid body 20 . Become.
In this manner, the sliding contact portion 52 that moves relatively to the braking portion 51 is brought into sliding contact with the braking portion 51 to suppress the force of rotation of the lid body 20 .

As the sliding contact portion 52 is further rotated, the sliding contact portion 52 comes into contact with the holding portion 53 and the lid body 20 stops rotating, as shown in FIG. 6(d).
At this time, the momentum of the lid body 20 to rotate is restrained by braking due to the sliding contact of the sliding contact part 52 with the braking part 51, so that the lid body 20 wobbles when the lid body 20 is opened. Therefore, the container body 10 does not move from its placed position due to shaking or the like.

Further, as the lid body 20 rotates in the direction away from the container body 10, the sliding contact portion 52 moved relative to the braking portion 51 shifts to the holding portion as shown in FIG. 6(d). Since it is held between it and the braking portion 51 by the 53, the opened lid body 20 is stabilized in its attitude and the opened state is maintained.

[Effects of Embodiment]
According to the household thin paper storage container 100 of this embodiment, when the user pinches the engagement releasing member 14 and the holding portion 12 to release the engagement between the locking portion 23 and the engaging portion 13, the biasing member Since the lid body 20 is automatically flipped up by the urging force of 30, it becomes easy to open the lid body 20 when using household thin paper.
In particular, in this household thin paper storage container 100, the sliding contact portion 52 on the side of the opened lid 20 slides in contact with the braking portion 51 on the side of the container body 10 to apply a frictional force to the rotating lid 20. Since the brake can be applied so as to suppress the force of rotation of the lid body 20, the lid body 20 and the container body 10 do not wobble due to the recoil of opening the lid body 20, and household thin paper can be stored. The position where the container 100 is placed does not shift or change direction.
In addition, when the lid 20 is opened, the sliding contact portion 52 on the lid 20 side is held between the braking portion 51 and the holding portion 53 on the container body 10 side. It can be maintained in that posture.

With such a household thin paper storage container 100, the household thin paper storage container 100 will not be displaced from the position where it is placed when the lid 20 is opened. The cover 20 of the thin paper storage container 100 can be suitably opened, and the household thin paper P can be taken out from the storage container 100 and used.

[Modification]
It should be noted that the present invention is not limited to the above embodiments.
For example, as shown in FIG. 7A, when the sliding contact portion 52 moved relative to the braking portion 51 contacts the holding portion 53 and the rotation of the lid body 20 is stopped, the sliding contact portion A convex portion 52 a provided on the braking portion 52 may have a structure that engages with a concave portion 51 a provided on the end point side of the braking portion 51 . With the household thin paper storage container 100 having such a structure, the open lid body 20 can be more preferably maintained in that posture.
Further, as shown in FIG. 7(b), when the sliding contact portion 52 moved relative to the braking portion 51 contacts the holding portion 53 and the rotation of the lid body 20 stops, the sliding contact portion A convex portion 52 a provided on the holding portion 52 may have a structure that engages with a concave portion 53 a provided on the holding portion 53 . With the household thin paper storage container 100 having such a structure, the open lid body 20 can be more preferably maintained in that posture.

Further, for example, as shown in FIGS. 8A and 8B, as the lid body 20 rotates in the direction away from the container body 10, the sliding contact portion 52 slides against the braking portion 51 from the starting point side. The contact area between the sliding contact portion 52 and the braking portion 51 may be larger on the end point side.
Even in the household thin paper storage container 100 having such a structure, as the sliding contact portion 52 rotates toward the end point of the braking portion 51, the frictional force between the sliding contact portion 52 and the braking portion 51 gradually increases. Therefore, it is possible to suitably suppress the force of rotation of the lid body 20 .
Note that even if the braking portion 51 has a substantially circular arc shape in which the height (thickness) of the one end side and the other end side is the same, the sliding contact portion 52 is closer to the end point side than the starting point side where the braking portion 51 slides. If the contact area between the sliding contact portion 52 and the braking portion 51 is larger, as the sliding contact portion 52 rotates toward the end point of the braking portion 51, the contact area between the sliding contact portion 52 and the braking portion 51 increases. Since the frictional force between and gradually increases, the force of rotation of the lid body 20 can be suppressed.

Further, as the lid body 20 rotates away from the container body 10, the upper surface of the braking portion 51 (sliding contact) is closer to the end point side than the starting point side where the sliding contact portion 52 slides on the braking portion 51. The width of the surface) may be formed so as to gradually widen.
Even in the household thin paper storage container 100 having such a braking portion 51, as the sliding contact portion 52 rotates toward the end point side of the braking portion 51, the contact area between the sliding contact portion 52 and the braking portion 51 increases. Since the force gradually increases and the frictional force between the sliding contact portion 52 and the braking portion 51 gradually increases, the force of rotation of the lid body 20 can be suitably suppressed.

In the above embodiment, regarding the configuration of the rotating portion 50, the braking portion 51 (and the holding portion 53) is provided at the container hinge portion 11 of the container body 10, and the sliding contact portion 52 is provided at the lid hinge portion of the lid body 20. Although the case where it is provided in the portion 21 has been described as an example, the present invention is not limited to this.
For example, the braking portion 51 (and the holding portion 53 ) may be provided on the lid hinge portion 21 of the lid body 20 and the sliding contact portion 52 may be provided on the container hinge portion 11 of the container body 10 .
Even in the rotating portion 50 configured in this manner, the sliding contact portion 52 that moves relatively to the braking portion 51 as the lid body 20 rotates away from the container body 10 moves away from the container body 10 . Sliding contact with the braking portion 51 can suppress the force of rotation of the lid body 20 .

In addition, it goes without saying that other specific details such as the structure can be changed as appropriate.
