And a lower edge formed with an inverted U-shaped bearing groove. The operating lever covers the rib and rotates via a lateral lever shaft provided on the upper side of the rib. In addition to being freely movable, the inner surface of which can be brought into contact with at least the front edge of the rib, an engaging projection is provided at the lower end, and a ridge for urging the entire operation lever toward the side closer to the rib is provided. On the other hand, on the other hand, a concave portion is provided on the side edge of the box body and a horizontal shaft is fixed to the concave portion, and the horizontal shaft is detachably fitted into the inverted U-shaped bearing groove of the rib and the engaging member It is assumed that the escape is restricted via the mating protrusion. Lower outside corners of the recessed portions formed shall contact the outer surface of the swing has been operating lever on the horizontal axis around those by regulating the opening of the lid to the predetermined angle in conjunction with the lid.

[0005]

When the lid and box are connected, the horizontal axis is the reverse U of the rib.
The operation lever is fitted in the U-shaped bearing groove, the inner surface of the operating lever is elastically pressed against the front edge of the rib by the spring, and the engaging projection faces the lower edge of the rib so that the horizontal axis is in the inverted U-shaped bearing groove. It is surely restricted from coming out of the box body, so that the lid body is hingedly opened around the horizontal axis without coming off from the box body. Then, when the lid is opened to the maximum,
The outer corner of the lower end of the recess contacts the outer surface of the operating lever that is pivotally displaced together with the lid to support it, while the inner surface of the lever contacts the front edge of the rib and is supported thereby. It will be one. Thus, the lid body is held at a constant angle through the lower outer corner of the recess, the operating lever, and the rib in a row in contact with each other. The position is maintained in a state in which the bonding strength and the supporting strength are extremely higher than those in the case where there is not.

On the other hand, when the lid is removed from the box, the operating lever is swung around the lever shaft against the urging force of the spring, whereby the engaging projection is moved to the position off the horizontal axis. The lateral axis within the inverted U-shaped bearing groove that has been moved is allowed to exit therefrom. If this condition is maintained and the lid is lifted upwards, the horizontal axis will come out of the inverted U-shaped bearing groove, allowing the lid to be opened and simultaneously pulling the front and rear operation levers outward. This makes it possible to remove the lid from the box.
