DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of the present invention will be described with reference to FIGS.
[0008]
In the blank of the box body 1 shown in FIG. 1, the bottom wall 2, the side wall 3, the top wall 4, and the side wall 3 are sequentially arranged from the right side. A rear plate 5 is provided below the bottom wall 2 and the top wall 4, and a rear piece 6 is provided below the side wall 3. An inner bottom plate 7 is provided above the bottom wall 2, and an upper side of the top wall 4. The inner top plate 8 is continuously provided.
[0009]
An inner plate 9 and a rear plate 10 are sequentially provided on the upper side of the side wall 3, and a guide groove 11 is formed on the inner plate 9 at a side edge facing the inner top plate 8. Further, a passage piece 12 is connected to the outer edge of the bottom wall 2, and a sealing hole 13 is provided in the ridge portion of the side wall 3 and the inner plate 9.
[0010]
On the other hand, in the blank of the lid member 14 shown in FIG. 2, the holding plate 15, the lid plate 16, and the lid back plate 17 are sequentially provided from the lower side, and sandwiching pieces 18 are provided on both side edges of the holding plate 15. ing. The lid plate 16 and the lid back plate 17 are provided with hand-holding holes 19 symmetrically about the ridgeline, and a sealing piece 20 is continuously provided on one side edge of the lid plate 16.
[0011]
To assemble the blank, as shown in FIG. 3, in the box body 1, the bottom wall 2, the pair of side walls 3, 3, and the top wall 4 are bent into a rectangular tube shape, and the passage piece 12 is turned to the opposite side wall 3. After the rear plate 5 and the rear piece 6 are combined to form the rear wall 21, the inner top plate 8 is bent inward and fixed by engagement between the protrusion and the hole.
[0012]
Further, in the lid member 14, the lid back plate 17 is attached to the back surface of the lid plate 16, the sealing piece 20 is folded in half, and the protrusion at the tip is engaged with the hole at the base end. The folded state is maintained, and the insertion piece 18 is bent inward.
[0013]
Then, the holding plate 15 of the lid member 14 is inserted into the box body 1, the inner plate 9 is bent inward, the sandwiching piece 18 is sandwiched between the side wall 3 and the inner plate 9, and the rear abutment plate 10 is attached to the rear wall. Next, the inner bottom plate 7 is bent inward, the projections on both side edges thereof are engaged with the notches of the inner plate 9, the lid plate 16 is pulled out from the box body 1 and closed, and the sealing piece 20 is closed. When inserted into the sealing hole 13, the cardboard box shown in FIG. 4 is obtained.
[0014]
In the cardboard box assembled in this way, when storing documents, as shown in FIG. 5, the bottom wall 2 is placed on the shelf with the bottom wall 2 down, the lid plate 16 is opened, and the lid member 14 is attached to the box body 1. When pushed in, the holding plate 15 and the lid plate 16 are inserted into the guide groove 11 and the lid member 14 is supported by the inner plate 9, so that documents can be taken in and out without supporting the lid plate 16 by hand.
[0015]
When the lid member 14 is pulled forward, the lid plate 16 is folded downward from the holding plate 15 and closed as shown in FIG. The slipping out of the sheet is prevented by the sandwiching piece 18.
[0016]
【The invention's effect】
As described above, in the cardboard box according to the present invention, since an open cover plate is slidably supported by the inner side plate of the box body, without support by hand cover plate, it can be out documents.
