[0028]

Since the present invention is constructed as described above, according to claim 1, the upper lid is pushed inward by the tray with one hand to open the inside, and then the lower lid is placed on the tray. The upper and lower lids can be opened greatly by holding the tray in place, and the lid can be held at the lid opening position.Therefore, it is not necessary to hold the lid at the lid opening position with another hand. It is possible to easily insert a simple container or the like in the supporting state of the above-mentioned bearing, and it is possible to completely eliminate the conventional defect that the input material is discharged to the outside by the lid.

Simultaneously with the completion of the insertion of the simple container or the like into the box body, the upper lid is rotated down and closed by its own weight, and the lower lid is also closed by this closing power, so the upper lid and the lower lid together. Also, the lid is relatively gently closed, and when the lid is closed, the lid does not repeatedly swing back and forth.

According to the second aspect of the present invention, since the pivot for pivotally connecting the upper and lower lids and the link engages with the guide groove and is guided, the rotation allowable angle between the open lid and the closed lid is restricted. As a result, the lower lid does not open to a larger angle than necessary when the tray is placed, and therefore the operability can be improved when inserting a simple container or the like, and the upper and lower lids can be placed at the predetermined positions. You can close it exactly.
