[0002]

2. Description of the Related Art An appropriate cut is made in a single sheet of material such as cardboard, and a side wall is bent so as to rise vertically from a bottom plate and connected to each other, so that the body and the lid are assembled and placed, respectively. Conventionally, it is widely used to store articles. For example, cakes, shirts, towels,
A storage box for high-quality gifts is an example. However, the assembled empty box occupies a place, and was an obstacle in an unused period until actually used for storing articles.

[0003]

Among the boxes, a box for storing a particularly bulky article wastes more space when empty. For example, after the box is manufactured, the storage space until delivery, the space occupied by the transportation means (packing bed) for transportation and delivery, and the storage before the goods are actually stored at the customer receiving the delivery and delivered to the customer How to secure a place or the like directly affects the cost, and is a problem for those skilled in the art. For this reason, there is a strong demand for reducing the volume of empty boxes to save space.

[0004]

[MEANS FOR SOLVING THE PROBLEMS] Of the box body and the lid,
Dramatically reduces the space occupied by folding at least the body part, and by allowing the folded body part to be completely accommodated in the hexahedron of the dish-shaped lid part To be able to do it.

【Example】

(First Embodiment) In this embodiment, the lid portion 1 of the box will be described as being assembled from the beginning and having a dish shape. 2, only part 2 of the box, for example, cardboard, flexible sheet material is first prepared, such as plastic, to form a development pattern of the box by punching the pattern of scheduled single material that.

Here, the predetermined pattern is a bottom plate portion 3 forming a box, side wall portions 4 to 7 connected to folding lines 3a to 3d forming four sides of the bottom plate portion 3, and each side wall. Side edges 4a to 7a at the ends of which portions are separated by fold lines 4b to 7b, and ears 4 which project from both side surfaces of the side walls 4 and 5 and serve as connecting means for the adjacent side walls 6 and 7
c and 5c, which indicates a development pattern of the body part. The fold lines 3b and 3d are bent 180 degrees in a mountain fold state to form a ridge. In this case, since the appearance is not impaired, priority is given to making it easier to maintain the mountain fold state. It is good to add a half cut to

As described above, the process for punching out the developed pattern includes the pressing process of the fold line portion and the half-cutting or V-shaped valley forming process for facilitating and maintaining the folding line. It is common knowledge of those skilled in the art, and in this regard, the present invention is also based on the common sense.

In FIG. 3, the side edges 4a to 7a are valley-folded along fold lines 4b to 7b as shown by arc arrows 11 in FIG. Then, at least the central portion of the overlapping portions of the bent side wall portions 4 to 7 and the side edges 4a to 7a, except for both ends, is fixed to each other. The fixation is preferably performed by normal gluing or heat fusion (hot melt) using a synthetic resin adhesive material such as vinyl acetate.

However, the fixing means is not limited to this, and includes, for example, normal gluing, adhesive tape, double-sided adhesive tape, a stapled stapler (so-called stapler), superimposed paper, sheets, etc. Means for tying the parts together by half-punching themselves in the depth direction or the circumferential direction of the punch holes and binding them together (for example, a paper lock [trademark of Sunstar Bungu Co., Ltd.]), a male and female engaging hook, etc. It may be fixed.

As described above, if the both ends of the side edges 6a, 7a which are folded in the valleys on the side wall portions 6, 7 and are superimposed thereon are not intentionally fixed, the body portion can be assembled and used later. When trying to assemble the box with the respective side wall portions standing vertically, the ear portions 4c, 5c of the side wall portions 4, 5 are not overlapped with the adjacent side edges as shown by arc arrows 12 in FIG. It can be inserted into the part. By assembling in this manner, a state in which the body part is in a deep dish for storing articles can appear. However, ear part 4
c and 5c need not necessarily be inserted. It is also possible to simply superpose and appropriately select and fix a means suitable for the purpose among the various fixing means as described above. In this embodiment, the ears 4c and 5c are formed over the entire length of each side wall portion (when assembled for use) in the height direction. May be.

In the case of an embodiment in which the ear is inserted, the inserted portion, the inserted portion, or both may be fixed, for example, as described above. However, even if it is not fixed, the lid portion 1 is put on the article after it is stored, so that not only the strength is not practically hindered but also convenient for disassembly or refolding after use. It is. Next, in FIG.
A broken line shows a state in which the side wall portions 6 and 7 shown in FIG. 3 are bent by being rotated by 180 ° as shown by the arc arrows 13 and turned to the back side of the bottom plate portion 3.

Finally, in FIG. 5, the valley is folded at the folding lines 3a and 3c as shown by the arc arrows 14 in FIG. Then, the ears 4c, 5c
Shows a state where is bent vertically.

FIG. 5 shows the body of the folding assembly box of the present invention.
This shows the folding completed state. Vertically bent ears 4
Although the heights of c and 5c do not need to be so strict, it is desirable to design the height substantially equal to or slightly lower than the depth of the dish-shaped lid portion 1 as described above.
Thereby, the body part 2 after the completion of folding can be completely stored in the lid part 1 in a stable state.

FIG. 1A shows the body after folding is completed.
Minute2FIG. 1 (b) shows a lid used in combination therewith.
part1FIG. 1 (c) shows the body after folding is completed.2
But the lid part1Housed inside and compact
Is shown.

(Second Embodiment) A second embodiment in which the folding order is changed
6 and 7 are shown in FIGS. The folding order up to FIG. 3 of the first embodiment is the same, and the subsequent folding order is changed as follows. That is, in the first embodiment, the side wall portions 6 and 7 are folded under the bottom plate portion 3 to obtain the state shown in FIG. However, when the side wall portions 4 and 5 are folded below the bottom plate portion 3 instead of folding the side wall portions 6 and 7 below the bottom plate portion 3, the state shown in FIG. 6 is obtained. Next, the side wall portions 6 and 7
Is folded to the upper side of the bottom plate part, the folding is completed,
It is possible to accommodate in the lid portion 1 as shown in FIG.

[0016] (Configuration of the lid portion 1) the lid portion 1, Fig. 1
A hexahedron as exemplified in (b), one surface of which forms an open surface and forms a dish shape, and the open surface of the dish shape is placed on the portion 2 to form a storage box. Any configuration can be used. As a material of the lid portion 1 , for example, it is preferable to assemble a cardboard, a flexible sheet material made of a polymer material, or the like, but is not limited thereto. For example, a thin metal plate such as an aluminum plate is formed into a dish shape. It may be integrally formed by pressing or by molding the polymer material into a dish shape.

When made of a flexible sheet material, the side wall portions of the lid portion 1 are fixed to each other by any means such as the above-mentioned gluing and stapling. In addition, in order to reduce the volume occupied by the lid portion 1 when not in use, it is also possible to implement a mode in which the side wall portion excluding the top plate portion is flattened in a crushed state. In this case, of course, cardboard, "flexible" sheet material made of a polymer material, etc. are preferred.

FIGS. 8A to 8C show an example of a folding order for flattening the lid portion 1 in a crushed state. However, this is merely an example, and the present invention is not limited to this. However, it is not intended that the novel manner or folding order of the lid part 1 be claimed.

(Assembly of body part) An assembling procedure of a folding assembly box according to the first embodiment of the present invention will be exemplified. First, the body part 2 housed in the folded state is taken out from the lid part 1 , the side wall parts 4 to 7 are set upright so as to surround the bottom plate part 3, and adjacent side parts 4c, 5c are used. Interconnect with each side wall portion.

One example of the interconnection is that, as described above, the ears 4c, 5c of the side wall portions 4, 5 are connected to the unfixed overlapping portions of the adjacent side edges as shown by the arc arrows 12 in FIG. Is to insert it. By assembling in this manner, a state in which the body part is in a deep dish for storing articles can appear. However, the ear portions 4c and 5c do not necessarily have to be inserted. It is also possible to simply superpose and appropriately select and fix a means suitable for the purpose among the various fixing means as described above.

When inserted, the inserted portion, the inserted portion, or both may be fixed, for example, as described above.
However, even if it is not fixed, the lid portion 1 is put on the article after it is stored, so that not only the strength is not practically hindered but also convenient for disassembly or refolding after use. It is.

[0022]

In summary, the important point of the present invention is that when the side wall portions 6, 7 opposed to each other across the bottom plate portion 3 are folded below (or above) the bottom plate portion 3, the side wall portion 4, 5 is folded above (or below) the bottom plate portion 3 to adopt a folding mode suitable for space saving.

Thus, not only the compact folding mode most suitable for the purpose is realized, but also the volume expansion due to the restoring force from the folded state can be suppressed and stabilized. Then, the volume of the box of the present invention when folded and not stored is the volume of the conventional adhesive box or the volume when the folding assembly box of the present invention is assembled. 1
It is reduced to about ３ to １ ／, and the space saving effect is great.
