Description

[Detailed description of the invention] This invention relates to an assembly box that is constructed by folding a single board and is used for organizing documents, etc., and documents stored upright inside the box may fall over or slide downward. It was designed so that it could be organized without any confusion.

Next, the details will be explained with reference to the illustrated embodiment. FIG. 1 shows the assembled box, and FIG. 4 shows the folded state. 5,
Through 6, 7, 8, the front plate 1, the right side plate 2, the rear plate 3,
The left side plate 4 and the adhesive piece 9 are arranged in series, and each plate 1, 2,
Bottom pieces 1', 2', 3', and 4' are connected to the lower edges of 3 and 4 via transverse fold lines 10, respectively.

In this assembly box, each plate 1, 2, 3, 4 and the adhesive piece 9 are bent inward from the vertical fold lines 5, 6, 7, 8, respectively, at almost right angles to each other, and the adhesive piece 9 is attached to the edge of the front plate 1. By gluing it to the inside of the edge, the peripheral wall of the box will be constructed, so next, for example, attach the bottom piece 1' of the front plate to the transverse fold line 10.
Bend it inward from the side plate, and attach the bottom piece 2' of the side plate to the bottom side.
4', fold the bottom piece 3' of the rear plate under it, and insert the locking protrusion 3'' upward from the notch 1'' in the center of the front plate bottom piece 1' to lock it, and the bottom plate is closed. The parts are assembled and the box body is completed.

The illustrated assembly box has a front plate 1 lower than a rear plate 3, and the upper edges of each plate 1, 3 are connected by inclined edges 4a, 2a at the upper ends of left and right side plates 4, 2, respectively. 1
Reference numeral 1 denotes a reinforcing plate that is connected to the upper edge of the rear plate 3 via the horizontal fold line 12, and after folding it into the inside of the box, the insertion protrusions 13, 13 provided on the side edge of the reinforcing plate are connected to the vertical fold line 6 of the side plates 2, 4. , 7 and are locked and fixed in engagement holes 14, 14 provided along the lines 7, 7. Reference numeral 15 denotes a hand hole bored through the rear plate 3 and the reinforcing plate 11.

A folding plate 16 is placed on the upper edge of the front plate 1 along a horizontal folding line 1.
The folding plate 16 is connected to the inner surface of the side plates 2 and 4 by locking its side edge 16' to the inner surface of the side plates 2 and 4 at an appropriate angle.
An appropriate distance a is maintained between the rear plate 3 and the rear plate 3. The width of this folding plate 16 is set to be slightly larger than the inner width of the box body, and the folding plate 16 is fixed to the side plate by frictional resistance between the side edge 16' of the folding plate 16 and the side plates 2 and 4. As shown in FIG. 3, an uneven strip 18 is provided on the inner surface of 2 or 4, or both, by pressing etc.
An engaging portion 16'a of the side edge 16' that protrudes slightly laterally may be locked. Alternatively, engagement holes may be arranged in an arc shape at appropriate intervals in the side plates 2 and 4, and an insertion protrusion provided at an engagement portion on the side edge of the folding plate may be engaged with the engagement holes. In the figure, reference numeral 19 denotes a pull opening provided in the folding plate 16 for inserting a finger when the plate is pulled out.

As mentioned above, the assembly box of the present invention is designed to maintain an appropriate distance between the edge 16'' of the folding plate 16 and the rear plate 3, so it can be erected inside the box as shown in FIG. 2, for example. Place the stored documents, files, etc. b on the rear board 3.
It can be clamped between the edge 16'' of the folding plate 16 to prevent it from falling inward, and also to prevent it from wobbling during transportation. It is extremely convenient because it prevents the document from slipping down and the holding interval can be adjusted appropriately by changing the angle of the folding plate 16 depending on the number of documents.

This box body can be folded as shown in Fig. 4 by unlatching the bottom plate portion and returning the rear reinforcing plate 11 and folding plate 16 to their original positions by performing the reverse operation of the above-mentioned assembly, and can be folded for storage, etc. It's convenient.
