The push lid 15 of the trash container 11
Is configured such that by adjusting the urging force of the coil spring 46 or the damping effect of the rotary damper 51, the angular velocity when the push lid 15 is moved upward can be arbitrarily finely adjusted.

The operation of the trash container 11 will be described below. The trash container 11 configured as described above includes a trash container main body bottom portion 12, an upper closing member 14, and a push lid 1.
After injection molding 5, they are assembled. When assembling the trash container 11, first, the coil portion of the coil spring 46 is inserted into the spring insertion projection 45 provided on the push lid 15, and one end of the coil spring 46 is engaged with the second spring locking portion 44.

When dust is to be inserted into the dust container 11, the dust insertion hole 13 is first opened by manually pushing the push lid 15 downward. At this time,
The push lid 15 in the state where the dust insertion hole 13 is closed (the state shown in FIG. 6A) resists the urging force of the coil spring 46 and pushes the rotating shaft 47 provided at the upper end thereof. It is pivoted downward by a predetermined angle to the center, and as shown in FIG. 6B, the front end of the dust insertion hole 13 is opened. When the push lid 15 is opened, the dust is dropped into the dust insertion hole 13 and dropped, so that the dust can be stored in the bottom 12 of the dust container main body. At this time, even if the pushing of the push lid 15 is stopped downward, the dust is easily stored in the bottom 12 of the dust container main body through the dust insertion hole 13.

That is, when the push lid 15 is stopped from being pressed downward, the push lid 15 is rotated upward about the rotary shaft 47 by the urging force of the coil spring 46, and the dust is removed. The insertion hole 13 is to be closed. However, the distal end of the rotary shaft 47 of the push lid 15 (engaging tube 48) is engaged with the distal end of the rotary damper 51 sandwiched by the upper closing member 14, so that the push lid 15 can be turned upward. As the dynamic velocity (angular velocity) advances in the closing direction, it is further attenuated, and it is possible to sufficiently gain time until the dust insertion hole 13 is closed. For this reason, dust passes through the dust insertion hole 13 before the opened dust insertion hole 13 is closed, and the dust passes between the upper surface of the push lid 15 and the peripheral edge of the dust insertion hole 13. It is possible to easily prevent the dust from being caught and caught.

Further, the push lid 15 is provided with the peripheral flange 42 and the peripheral edge of the dust insertion hole 13 at the moment when the dust insertion hole 13 is completely closed due to the rotation (upward movement) speed damping action of the rotary damper 51. Collision is effectively suppressed. For this reason, noise (collision sound) at the time of collision between the peripheral flange 42 and the peripheral edge of the dust insertion hole 13 is hardly generated, so that it is quiet. Further, the dust container 11 is always sanitary because the dust is hardly brought into contact with the upper surface of the push lid 15 and the peripheral portion of the dust insertion hole 13 by the rotation speed damping action.

The effects exerted by the above embodiment will be described below. The trash container 11 of the embodiment has a pivot shaft 47 as a rotating means for rotating the push lid 15 in both directions of opening and closing the dust insertion hole 13 at the joint between the push lid 15 and the upper closing member 14. A rotation bearing 33 is provided, and a rotary damper 51 for attenuating the rotation speed of the push lid 15 is provided. Therefore, dust can be easily inserted into the dust container 11 and noise (collision noise) after the dust is inserted can be easily reduced.

Further, since the dust container 11 is configured such that the dust does not easily come into contact with the upper surface of the push lid 15 and the peripheral portion of the dust insertion hole 13 when the dust is charged, it is always used in a sanitary manner. It is easy to do. In particular, the upper surface of the upper wall 41 constituting the push lid 15 is a place to be pressed by hand every time dust is inserted, and it is not preferable that dirt adheres to this surface. From this viewpoint, it can be said that the trash container 11 of the present embodiment is extremely superior to the above-mentioned conventional spring-openable push lid type trash container.
