Description

[Detailed description of the invention] The present invention is a flat box for storage and transportation, and when used, the box body is folded up to form a frame-like frame with the surrounding edges of the rectangular opening. Regarding paper boxes.

In this type of folded paper box, the bases of the side walls (adhesive pieces 5 described later) on the vertically long sides are fixed to the bottom and are stable, but the bases of the front and rear walls (adhesive pieces 5 described later) are fixed to the bottom and are stable. Piece 9) merely overlaps with the base, thus providing latching means at both ends of the base. However, when assembling the box, if the ends of the side walls are pulled forcefully outward,
The problem is that the latching portions may come undone, and the joint folding pieces at the corners (joint folding pieces 18 and 19, which will be described later) may also come apart.

The purpose of the present invention is to eliminate such drawbacks, and for this purpose, a connecting piece having a deletion part is provided in series on the outer joint folding piece and the inner end wall, so that the connecting piece can be easily removed when assembling the box body. This purpose is achieved by constructing one part as a lug and the other by forming an indentation between the outer wall and the inner joining fold.

Next, a preferred embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, adhesive strips are attached to the outer wall 2, the edge 3, the inner wall 4, and the bottom 1 along the respective fold lines 10, 11, 12, and 13 on both sides of the bottom 1. 5 are arranged in series, and on the other front and back, they overlap with the outer end wall 6, the edge surface 7, the inner end wall 8, and the bottom 1 through the respective fold lines 14, 15, 16, 17, and are hung at both ends. Bending stop pieces 9 that can be stopped are provided in succession. During assembly, the edge surfaces 3, 7
appears as a square picture frame. In addition, an outer joining fold piece 18 having a diagonal fold line 26 and an inner joining fold piece 19 having two diagonal fold lines 27' and 27'' extending in a V shape from the same base are set at the corner. Incidentally, an additional adhesive piece 20 is attached to the outside of this inner joint folding piece 19, which is in line with the adhesive piece 5.

In a preferred embodiment, the width of the inner wall 4 is smaller than the width of the outer wall 2 by about three times the thickness of the paper used. This is calculated by taking into consideration the sum of the part that rests on the bottom part 1, the part of the adhesive piece 5, and the difference with the outside size. The same applies to the width of the outer end wall 6 and the width of the inner end wall 8. The fold line 23 is preferably inclined inwardly as shown. As shown in FIG.
9 makes it easy to embrace and bend freely, and each end of the other two edge surfaces 3 and 7 becomes easy to join, and this region is reinforced. Cut edges 29 provided at both ends of the bent piece 9 are fitted into the cutout portions 33 during assembly.
The deleted portion 33 is provided on an extension of the edge surface portion 3, and the fold line 24 is provided on an extension of the crease line 13.

According to the present invention, the connecting piece 38 having the removed portion 39 is provided in series with the outer joint folding piece 18 and the inner end wall 8, so that when assembling the box (see FIG. 3), a part of the connecting piece 38 is attached. is formed as a protruding piece 38, and an indented part 40 is formed between the inner side wall part 4 and the inner connecting folded piece 19.

The structure of the developed paper pattern according to the present invention is as follows. Based on this paper pattern, each operation or process of gluing and folding can be performed by hand or continuously using a belt gluer, roll coaster, etc. Then, as shown in FIG. 2, the flat body is placed in a state where it can be folded up immediately.

Next, assembly is performed as follows according to FIG.

First, raise the inner wall part 4 and the outer wall part 2 on both sides which are lying flat, and at that time, push up the fold line 12 as a ridge line, fold in the fold line 11, and then raise the edge surface part 3.
is reliably formed into a shape, remains completely parallel to the bottom part 1, and does not tilt outward.

Further, since the other adhesive piece 20 is adhesively fixed to the outer wall 6, while pushing the combined folded piece 18 on the extension of the outer wall 2 inward along the fold line 26, When the outer end wall 6 is stood upright via the inner wall 4, the inner joining fold 19, which is an extension of the inner wall 4, has a width W ₂ between its diagonal ends by the V-shaped fold lines 27' and 27''. The half-folded joining piece 18 is sandwiched therein, facing the edge portion 7, and eventually the bending stopper 9 locks the cutting edge 29 into the removed portion 33, so that the other half-folded joint piece 18 is sandwiched therein. By folding the line 15 or 16, the protruding stopper piece 3 formed on a part of the connecting piece 38
8' is fitted into the indented portion 40, and the bending stopper piece 9 is immovably locked.

A top view of the box thus formed can be seen in FIG.

In this case, no matter how forcefully the end of the side wall, i.e. near the corner, is pulled outward, the two joining folds 19, 18 of the inner corner
The connecting pieces 38 prevent the box from being exposed or disassembled, and the protruding pieces 38 fit into the indentations 40 and cannot come off, so a box with double internal and external partitions extending from the sides and front to back can be obtained.
