In this case, the ends of the connecting piece of the partition and the folded pieces of the side plate are brought into contact with each other, and the split guideway is provided avoiding the fixed parts of the top flap and the folded pieces of the bottom plate. There is no overlap in plate thickness in the split guideway, and cutting can be performed with approximately uniform force over the entire length. In addition, since the connecting piece of the partition body and the folded piece of the side plate are assembled by butting their ends against each other, the main body sheet is formed into a rectangular shape, which eliminates wasted material due to notches, etc. Punching can be omitted. Also, the portions that require pasting processing and the overlap of materials are reduced.

"Example" Hereinafter, an example of the packaging box of the present invention will be described based on FIGS. 1 to 5. This packaging box also has the following:
Similar to FIG. 6, the structure is a combination of a main body sheet 1 made of corrugated cardboard and folded into a rectangular tube shape, and a partition body 3 that partitions an internal storage space 2 into a plurality of parts.

The main body sheet 1 has a bottom plate 4 as shown in FIG.
A side plate 5 and a top flap 6 are sequentially connected to both ends of the top flap 6 in a bendable manner, and on each side of the bottom plate 4, side plate 5, and top flap 6,
It has a basic configuration in which folded pieces 7, 8, and 9, all of which have the same width _W1 , are foldably arranged, and can be folded into a rectangular tube shape so that both top flaps 6 are turned inward. The length l ₁ of both roof flaps 6 is set to be 1/2 of the length l ₂ of the bottom plate 4.

In addition, the bottom plate 4 and the folded pieces 7 on both sides thereof are provided with perforations and a first divided guideway 10 formed by cutting tape or the like so as to cross the center portion in the width direction.
are provided, and both side plates 5 and folded pieces 8 on both sides thereof are provided.
In both cases, a second divided guideway 11 is arranged along the width direction. This first divided guideway 10 divides the packaging box into left and right halves, and the second divided guideway 11
is for dividing the packaging box into upper and lower halves, and in the second dividing guideway 11, the side plate 5 and the bottom plate 4 are
The distance l ₃ from the connecting part to the folded piece 7 of the bottom plate 4 is
The width dimension W is made equal to ₁ .

On the other hand, as shown in FIG. 3, in the partition 3, a connecting piece 13 is formed by making a notch 12 in the center of both widthwise ends of the cardboard along the width direction. By folding the connecting pieces 13 in half and spreading the connecting pieces 13 on both sides to the left and right, the whole is formed into an H-shape as shown in Fig. 2.The width of the entire partition 3 when formed into an H-shape is W ₂ is almost the same as the width W ₃ of the bottom plate 4, and the sum of the length l ₄ of each connecting piece 13 spread left and right and the width W ₁ of the folded piece 8 of the side plate 5 is:
It is assumed to be 1/2 of the length l ₂ of the bottom plate 4. The partition body 3 is also provided with a first divided guideway 14 and a second divided guideway 15 formed by perforations or the like. This first divided guideway 14 has both notches 1
2, and the second divided guideway 15 is provided in such a manner that the bent portion of the connecting piece 13 and a position slightly apart from the notch 12 are connected in an L-shape. The second divided taxiway 1
The distance l ₄ from the notch 12 in the main body sheet 1 is equal to the width W 1 of the folded piece 7 of the bottom plate 4, as in the case of the divided guideway 11 in the side plate 5 of the main body sheet ₁ .

When assembling a packaging box configured in this way, the divided guideway 1 in the center of the bottom plate 4 of the main body sheet 1 is
0 line as shown by arrow A in FIG.
is placed thereon, both side plates 5 are stood up so as to wrap around the partition 3, and each folded piece 8 is bent inward to connect the tip of the folded piece 8 and the connecting piece 13 of the partition 3. By butting them against each other, both sides of the storage space 2 between the side plates 5 are closed, and then the folded pieces 7 of the bottom plate 4 are bent to separate the connecting pieces 13 and folded pieces 8 in the abutted state.
The packaging box is assembled as shown in FIG. 1 by covering the outside of the box and joining them with adhesive or staples.

In the packaging box assembled in this way, the product is stored in the storage space 2 partitioned by the partition 3, both top flaps 6 are closed, and the folded piece 9 is connected to the folded piece 8 of the side plate 5 and the connecting piece of the partition 3. 13, and by joining these together, they are sealed and ready for transportation, etc., as shown in FIG. In this case, the ends of the connecting piece 13 of the partition 3 and the folded piece 8 of the side plate 5 are butted against each other to close both sides of the packaging box, so that the inner surface of the packaging box becomes flat and the storage space 2 The storage space 2 can be utilized to the maximum without creating a convex portion inside,
Even square products can be easily stored.

When displaying at a store, the packaging box is divided vertically from near the bottom by cutting the second divided guiding paths 11 and 15 of the main body sheet 1 and the partition body 3, respectively, and the upper part is removed. As a result, the top and sides of the product can be opened as shown in FIG. 5 while the product is stored.
In this case, as shown in FIG. 4, the packaging box is assembled by abutting the ends of the folded piece 8 of the side plate 5 and the connecting piece 13 of the partition 3, and the divided guideways 11, 15 are connected to the bottom plate 4. Since the folded piece 7 is provided at a position separated by width W ₁ from the connecting portion with the side plate 5, the second divided guideway 11,1
In No. 5, there are no overlapping portions of the cardboard, and the cardboard can be cut with substantially uniform force over its entire length, making the dividing operation easier.

In the illustrated example, the bottom plate 4, the partition body 3, etc. are divided into left and right parts, and the packaging box is made into two parts by cutting the first dividing guideways 10, 14 of the main body sheet 1 and the partition body 3. This small packaging box can also be divided into two small packaging boxes by cutting the second divided guideways 11 and 14 and using the remaining partition 3 as a back plate. It can be displayed in stores. In this case, the second divided guideways 11 and 14 may be cut after being divided into small packaging boxes, or the second divided guideways 11 and 14 may be cut into the state shown in FIG. 5 and then divided into two. It is also possible to divide them.

Furthermore, in this packaging box, the connecting piece 13 of the partition body 3 and the folded piece 8 of the side plate 5 are assembled by butting their tips against each other, and the width dimension W ₁ of the folded pieces 7, 8, and 9 is all the same. Therefore, the main body sheet 1 is formed into a rectangular shape as shown in FIG. 2, and there is no need to provide a notch as in the conventional example shown in FIG. 7, thereby eliminating waste and efficiently using materials. be able to. Moreover, in this packaging box, there is no need to provide a notch as described above, so it has become possible to manufacture the packaging box blank using only general corrugated paper manufacturing equipment without using a cutting die. Therefore, according to this packaging box, it is possible to produce blanks using the conventional cardboard manufacturing method and equipment as is, eliminating the need for cutting die processing when producing blanks.
It is possible to improve production efficiency and reduce manufacturing and equipment costs.

In addition, in this packaging box, the folded piece 8 of the main body sheet 1 is butted against the connecting piece 13 of the partition 3, so the folded piece that needs to be attached during manufacturing is a folded piece along the flow direction of the box assembly line. There are only the piece 7 and the folded piece 9. Therefore, the pressing and holding of the folded pieces 7 and 9 when pasting them can be done simply by providing a guide along the flow of the assembly line. Therefore, this packaging box can be assembled using a device with a simple structure.

On the other hand, in the conventional packaging box shown in FIG. 6, the folding piece 24 located perpendicularly to the flow direction of the box assembly line is also attached, so that the conventional packaging box can be assembled. In some cases, it is necessary to use a complex structure that includes a mechanism that temporarily stops the movement of the box body when attaching the folding piece 24, and a mechanism that moves at the same speed as the packaging box to be assembled and holds the folding piece 24 in the vertical direction. equipment must be used.

Further, in the packaging box of the embodiment, as described above, the only parts to be pasted are the folded piece 7 connected to the bottom plate 4 and the folded piece 9 connected to the top flap 6, so there are few parts to be glued.

Furthermore, in this packaging box, the sides of the packaging box are formed by butting together the folded piece 8 of the side plate 5 of the main body sheet 1 and the connecting piece 13 of the partition 3, so that the overlap of materials is reduced. It also has the advantage of saving raw materials.

Note that the partition body 3 is not limited to this embodiment, and may be formed into an H-shape by connecting a pair of cardboard boxes bent back to back to each other in a U-shape. Further, the second divided guiding path 15 provided in the partition body 3 may be provided so that at least the portion of the top flap 6 to which the folded piece 9 is fixed can be removed.

"Effects of the Invention" As explained above, the packaging box of the present invention can provide the following effects.

(i) By covering and fixing the folded piece of the top flap from the outside of the connection piece of the partition body and the folded piece of the side plate, and by cutting each divided guideway between the main sheet and the partition body,
The upper part of the packaging box can be removed and the product can be displayed in the store with the products stored in it. Since the divided guideway is provided to avoid the part where the folded piece is stuck, there is no overlap in the thickness of the plate in the divided guideway, and it is possible to cut with almost uniform force over the entire length, resulting in good workability. .

(ii) Since the connecting piece of the partition body and the folded piece of the side plate are assembled with their tips butted against each other, the main body sheet can be formed into a nearly rectangular shape, and material loss caused by cutouts in the conventional example can be avoided. occur less often. Moreover, since the packaging box of the present invention does not require cutouts, the packaging box blank can be manufactured using only general corrugated paper manufacturing equipment without using a cutting die. Therefore, according to this packaging box, it is possible to manufacture blanks by using only the conventional corrugated paper manufacturing method and equipment, and it is possible to improve the efficiency of blank production and reduce manufacturing and equipment costs. .

(iii) By abutting the connecting piece of the partition and the folded piece of the side plate, the interior of the storage space becomes flat and no protrusions are formed, allowing efficient use of the storage space.

(iv) Since the side of the storage space was closed by matching the folded piece of the main sheet with the connection piece of the partition, the folded piece that needed to be attached during manufacturing was attached to the bottom plate and the top flap. , there is only a folded piece along the flow direction of the box assembly line. For this reason, the pressing and holding when pasting the folded piece can be done simply by providing a guide along the flow of the assembly line. Therefore, the packaging box of the present invention can be assembled using a device with a simple structure.

(v) Furthermore, in this packaging box, as mentioned above, the folded piece of the side plate of the main body sheet and the connecting piece of the partition body are butted against each other to form the side part of the storage space, and the part to be pasted is connected to the bottom plate. Since we only used the fold-back piece and the fold-back piece connected to the top flap,
There are fewer parts to glue, and there is less overlap of materials, which has the advantage of saving on raw materials.
