DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage box, and more particularly, to a storage box capable of preventing relative displacement of upper and lower storage boxes when stacked in a multi-stage type.

[0002]

2. Description of the Related Art Conventionally, a storage box is provided on the box body made of cardboard or the like so that an appropriate drawer can be taken in and out. In this type of storage box, since it is often used by being stacked vertically, a tongue piece enabling mutual engagement between the mating surfaces of the storage box and a slit for receiving the tongue piece are provided at relative positions. There is one that adopts a configuration that prevents displacement between the two. That is, a cut-and-raised tongue piece is provided on the top wall portion of the storage box, and a slit is formed in the bottom wall so that the tongue piece can be inserted. According to such a configuration, when stacking a plurality of storage boxes, the tongue pieces of the lower storage box are set to the upright posture, and this tongue piece is provided on the bottom wall of the upper storage box. By inserting it into the slit, it is possible to prevent relative displacement of each storage box.

[0003]

However, in the conventional configuration, since the tongue piece is formed by partially cutting and raising the top wall, when the tongue piece is in the upright posture, the tongue piece is partially formed on the top wall. The shape is such that a large hole remains. Therefore, if dirt or the like adheres to the lower surface of the bottom wall of the storage box placed on the upper stage, there is an inconvenience that the dirt enters the lower storage box. Moreover, since such a tongue piece is formed by cutting and raising, it cannot stably hold an upright posture against an external force in a direction orthogonal to the surface direction of the tongue piece. Thus, when an external force is applied to the storage box from the lateral direction, the upper and lower storage boxes are relatively displaced in the left-right direction.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of such inconvenience, and an object of the present invention is to enable connection between storage boxes without leaving a large hole in the top wall.
Another object of the present invention is to provide a storage box that can effectively prevent relative displacement between storage boxes.

[0005]

In order to achieve the above-mentioned object, a storage box according to the present invention comprises a substantially rectangular parallelepiped box body having an opening on the front side, and an inner member mounted inside the box body. A slit is provided in the outer peripheral side portion of the bottom wall of the box main body, and an outer tongue piece that can be raised with the outer peripheral side of the top wall as a free end is formed in the area of the top wall, while the inner member is When the outer tongue is erected, an inner tongue that can be erected as a base at a position substantially corresponding to the free end is provided so that the inner tongue can be inserted into the slit.
When the inner tongue is erected after being raised and positioned substantially flush with the top wall of the box body, the free end of the outer tongue presses and fixes the base region of the inner tongue. ing. According to such a configuration, a large hole is not left in the top wall by lowering the outer tongue after the inner tongue is in the upright posture, and the storage box can be maintained in a substantially closed shape. . Therefore, as compared with the conventional type in which a large hole is left due to the standing of the tongue piece, the possibility of dust entering the storage box can be reduced as much as possible. In addition, the free end of the outer tongue presses the base of the inner tongue to stabilize the posture of the base region, thereby enabling good displacement control of the inner tongue. In such a case, the relative displacement in the lateral direction can be effectively prevented.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION An inner member according to the present invention comprises an inner top wall attached to the inner surface of the top wall and an inner side wall connected to the inner top wall and attached to the inner surface of the side wall of the box body. A first interior material is provided, and the inner tongue is formed in a region of an inner top wall corresponding to the outer tongue. Accordingly, the inner tongue piece can be formed using the first interior material having a very simple structure. At this time, it is preferable to further provide a second interior material having an inner bottom wall and an inner rear wall that can be attached to each inner surface of the bottom wall and the rear wall of the box main body. The strength as a whole can be improved as a heavy structure. Therefore, when using a corrugated cardboard or the like as a molding material, it is sufficient to use a corrugated cardboard provided with a thickness that makes bending relatively easy, and assembly can be performed easily without burden.

[0007] It is preferable that an inner tongue inserted into the slit is continuously provided at an upper end of the inner rear wall, and the inner tongue is provided with a hook portion capable of engaging and disengaging with a forming edge of the slit. . With such a configuration, in addition to restricting the relative movement of the stacked storage boxes in the lateral direction,
Inadvertent lifting of the upper storage box can be prevented.
