Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a packaging box that can be packed into a small size without disassembling the box when not in use.

Conventional Structures and Problems Generally, cardboard boxes are large even when not in use, so they are unsuitable for transportation for reuse. Therefore, the flaps on the edge of the box are lengthened and the entire cardboard box is transported flattened, but accessories used inside the cardboard box, such as trays, cannot be accommodated in the flattened cardboard box. Therefore, the trays and the like are often transported either stacked on the outside of a flattened cardboard box and tied with string, or transported separately. Such transportation may result in the tray being lost or
Otherwise, they were easily damaged, the stringing process was troublesome, and they were unsightly.

OBJECTS OF THE INVENTION The present invention takes these problems into consideration and aims to make packaging boxes smaller when not in use, and to also allow accessories such as trays to be stored inside.

Structure of the Invention In order to achieve the above object, the present invention has a shallow bottom;
and a lower lid box having a square outer shape, and a rectangular body frame, and the square body frame overlaps each side piece of the first U-shaped member and the second U-shaped member, and overlaps each side piece. The first and second U-shaped members each have a mounting piece protruding from the bottom attached to the side plate of the lower lid box. and each piece is configured to be foldable into the lower lid box, and the width of at least one side piece of the U-shaped member located at the upper part when folded is approximately equal to the depth of the lower lid box. formed,
The packaging box has a structure in which the lower lid box is stacked on the side plate when folded, and the side pieces and the lower lid box can be freely combined by locking a stopper in a connecting hole formed in the side plate of the lower lid box. .

With this configuration, a used packaging box can be disassembled, other accessories such as a tray can be stored in the lower lid, and the square frame can be folded into a flat box, making it easy to transport for reuse. It is convenient, easy to pack, and has the effect that the rectangular frame or tray will not be lost or damaged.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In the figure, reference numeral 1 denotes a rectangular body frame, and 2 denotes a lower lid box having a rectangular outer shape, which has a relatively leaky bottom and can be freely fitted to the outer periphery of the lower lip of the rectangular body frame 1. The square body frame 1 has a vertical width a smaller than a width b of the lower lid box 2, and is formed by combining a first U-shaped member 1a and a second U-shaped member 1b. There is. The width of the side piece 3 of the first U-shaped member 1a is relatively small and approximately equal to the depth of the lower lid box 2. The side piece 4 of the second U-shaped member 1b is formed long, and the ends of the side pieces 3 and 4 are overlapped and connected by a coupling tool 6. In addition, the first
The U-shaped member 1a and the second U-shaped member 1b are formed by connecting mounting pieces 1e and 1f, which have the same dimensions as the depth C of the lower lid box, from the lower edge via bending lines 1c and 1d, respectively. The side pieces 3 and 4 have portions corresponding to the mounting pieces cut out. Specifically, the above-mentioned connection is carried out by overlapping the side pieces 3 and 4 of the first and second U-shaped members 1a and 1b, and through the corresponding connection holes 7,
Insert the coupling tool 6 having a clamp function into 8,
It is clamped by the clamp piece 6a. In addition,
This coupling tool 6 has clamp pieces 6a connected by a hinge, and can be easily removed by folding the clamp pieces 6a inward. Also, the depth C of the lower lid box 2 and the first U-shaped member 1a.
The widths of the side pieces 3 are approximately the same. Further, a locking hole 10 is provided in the side plate of the lower lid box 2.
A tray 11 for collective packaging is provided inside the rectangular body frame 1. This tray is made of a synthetic resin plate, has an outer shape that fits within the lower lid box 2, and has a number of recesses 12 for storing items. The shape of the tray part 12a forming the article storage recess 12 is tapered so that the diameter of the lower part gradually becomes smaller. 12
It has become a good fit.

In the above structure, when transporting goods, first, the first and second U-shaped members 1a and 1b are combined with the connector 6 to form the rectangular body frame 1, and the mounting piece at the lower part of the rectangular body frame 1 is assembled. 1e and 1f are stacked on the side plate of the lower lid box 2 and fixed using the coupling tools 6 that are engaged with the coupling holes 9 and 10. Next, the tray 11 is stored in the storage section 12, and is sequentially placed inside the rectangular body frame 1.Finally, the upper flap part 5 of the rectangular body frame 1 is covered, and the tray is sealed with the above-mentioned binding tool or tape.

Next, when the transportation of the goods is completed, the upper seal is removed, the coupling tool 6 that connects the side pieces 3 and 4 of the first and second U-shaped members 1a and 1b is removed, and the tray 11 is first closed with the lower lid. Put it in box 2. Next, the side pieces 4 and flaps 5 of the second U-shaped member 1b are folded inward and folded. From above, the first U-shaped member 1a
Fold the flap 5 inward, align the coupling hole 7 of the side piece 3 of the first U-shaped member 1a with the coupling hole 10 of the lower lid box 2, and then align the coupling tool 6 removed.
It locks in place and transforms into a flat box. FIGS. 3 and 4 show this state.

5 and 6 show other examples of the present invention, in which the first and second U-shaped members 13a and 13b are connected to the side piece 1.
4 and 15, and the side piece 14 is relatively narrower than the side piece 15, and has a width that is approximately the same as the depth of the lower lid box 2. Further, the side piece 15 having a large width has a bending line 13c in a diagonal pattern, and the bending line 13c is located at the same dimension as the depth c of the lower lid box 2.
It contains d.

When transportation in the upper configuration is completed, the tray 11 is placed in the lower lid box 2 in the same manner as described above. Next, bend the bend line 13c of the side piece 15 of the first U-shaped member 13b inward and fold it into the lower lid box 2, then fold the first U-shaped member 13a in the same way, and
The hole 17 of the lower cover box 2 and the hole 10 of the lower lid box 2 are locked with the coupling tool 6. FIG. 6 shows the state in the middle of folding.

Effects of the Invention As is clear from the above examples, the packaging box of the present invention can be made extremely compact after use, which is advantageous for transportation for reuse, and accessories such as trays can be stored inside. Since it can be stored, there is no loss of powder or damage, and since it uses a locking device, there is no need for work such as hanging a string, which is highly effective.
