  However, in the conventional configuration provided so far, the rear edge of the opening / closing lid and the handle collide with the container main body each time the opening / closing opening / closing lid is opened and closed to accommodate the garbage in the container. As a result, an unpleasant collision sound is generated. In particular, when the container is installed in an apartment house or the like and used in the middle of the night or early morning hours, the impact sound deteriorates the living environment of the residents, which is a serious problem.

  Further, it is required to make the opening / closing operation of the opening / closing lid easier and to ensure the safety of the opening / closing operation. For example, if the lid opening / closing structure of a container with a push-on lid disclosed in Patent Document 3 is to be applied to a garbage collection container, there is a risk that a person around will come into contact with the rotating lid.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a garbage collection container in which collision noise is mitigated when a rotary opening / closing lid is opened and closed, and which is excellent in safety.

  The present invention is a waste collection container comprising a container main body and a pivotable opening / closing lid that opens and closes a garbage input port formed in the front upper portion of the container main body, the container main body having a rectangular shape in plan view A pair of left and right side plates each of which is erected on a pair of left and right side edges opposed to each other in the bottom plate portion, and has a semicircular arc shape with an upper portion convex upward, and a rear edge of the bottom plate portion and the bottom plate portion A rear plate portion that is formed over the upper portion of the side plate portion along the shape of the rear side edge of the side plate portion while being passed between the side edges of the side plate portion from the lower rear edge of the pair of left and right side plate portions. And the front plate portion formed along the front edge shape of the side plate portion while being passed between the side edges of the side plate portion from the front edge of the bottom plate portion and the front lower edge of the pair of left and right side plate portions. An opening formed between the upper edge of the front plate portion and the upper edge of the rear plate portion in the container body is the waste inlet. The pivotable open / close lid is extended toward the center of the arc of the open / close lid body from the open / close lid main body having an upwardly convex arc shape and the left and right sides of the open / close lid main body. A pair of left and right extension parts, and an arc center part corresponding to the arc center of the opening / closing lid body is provided in the extension part, and a shaft support part is set in the arc center part, and the The pivotable opening / closing lid is pivotally supported by the pair of left and right side plates, and when the pivotable opening / closing lid pivots forward and downward along the upper edge of the semicircular arc of the side plate, the garbage inlet is closed. When the pivotable opening / closing lid pivots rearward and upward along the semicircular arc-shaped upper edge of the side plate portion, the dust inlet is opened, and the pivot support portions at the left and right ends of the pivotable opening / closing lid are opened. At least one of these is provided with a one-way rotary damper that generates a resistance force only when the pivotable opening / closing lid is pivoted in the closing direction. It is dust collection container, characterized in that.

  In such a configuration, after the user throws in the waste through the waste inlet, the rotary opening / closing lid is turned in the closing direction to close the waste inlet, and the function of the one-way rotary damper Thus, a resistance force is generated against rotation in the closing direction. For this reason, even if the user releases his hand during the closing operation, the rotary opening / closing lid has the resistance force by suppressing the descent speed due to its own weight by the resistance force. It closes by rotating more slowly than the case where it falls only by its own weight without being given. Therefore, it is possible to prevent a large collision sound from being generated due to a strong collision between the rotary opening / closing lid and the container body at the time of closing.

  In the above configuration, a buffer portion is provided in the rotary opening / closing lid and / or the rear plate portion, and when the garbage inlet is in an open state, the rotary opening / closing lid and the rear The buffer portion may be interposed between the plate portion and the plate portion.

  By adopting such a configuration, not only when closing, but also when the user opens the garbage inlet to throw in the garbage, the buffering action of the buffering portion causes the rotary opening / closing lid, the container body, It is possible to prevent a large collision sound from being generated due to the collision.

  Further, the pivotable opening / closing lid is disposed in the container main body, and a stopper portion that protrudes forward and has a substantially horizontal surface is disposed on the inner surface of the rear plate portion, and the pivotable opening / closing lid. The buffer portion is disposed in a substantially horizontal plane at the rear edge portion and / or the upper portion of the stopper portion of the rear plate portion, and the rotary opening / closing lid is rotated in the opening direction so that the dust inlet is opened. In this case, the rear edge portion may be pressed against the stopper portion via the buffer portion, and the pivotable opening / closing lid may not be pivotable in the opening direction.

  With this configuration, it is possible to reliably stop the rotation of the rotary opening / closing lid in the opening direction at a position where the dust inlet is appropriately opened without generating a loud collision sound. In addition, since the pivotable opening / closing lid is disposed in the container body, there is little possibility that the pivoting opening / closing lid that rotates rotates will come into contact with a person around.

  Further, the angular range in which the one-way rotary damper can rotate is regulated, and when the dust inlet is in an open state, the one-way rotary damper reaches the maximum angular position and the rotary opening and closing is performed. The lid may be unrotatable in the opening direction, and a gap may be provided between the pivotable opening / closing lid and the rear plate portion so that they are not in contact with each other.

  In such a configuration, the one-way rotary damper can reliably stop the rotation of the rotary opening / closing lid in the opening direction at a position where the dust inlet is appropriately opened. In addition, when the garbage inlet is in an open state, the rotary opening / closing lid and the container main body are not in contact with each other, so that it is possible to reliably generate a collision sound when the rotary opening / closing lid is opened. Can be prevented.

  By the way, as described above, when the one-way rotary damper reaches the maximum rotation angle, the rotation of the rotation type opening / closing lid stops properly. A load is applied to the one-way rotary damper, which may reduce the useful life of the product as a whole.

  Therefore, the one-way rotary damper is disposed only on one of the shaft support portions, and the other shaft support portion is provided with a rotation angle range restricting means for restricting the rotation angle range of the rotation type opening / closing lid. When the dust inlet is in an open state, the rotation angle range restricting means makes the rotation type opening / closing lid impossible to rotate in the opening direction, and the rotation type opening / closing lid, the rear plate portion, A configuration is proposed in which a gap is provided between them so that they are not in contact with each other.

  By adopting such a configuration, it is possible to reliably stop the rotation of the rotary opening / closing lid in the opening direction at a position where the dust inlet is appropriately opened without applying a load to the one-way rotary damper. it can. In addition, when the garbage inlet is in an open state, a gap is provided between the rotary opening / closing lid and the rear plate portion so that they are not in contact with each other. It is possible to reliably prevent the occurrence of collision noise when operated.

  The garbage collection container of the present invention has an excellent effect that can mitigate a collision sound generated when the rotary opening / closing lid is opened and closed.
