[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a packaging box for packaging various articles, for example, spherical fruits and vegetables.

[0002]

[Prior art]

 As shown in FIG. 6, a conventional packaging box B is assembled by bending a pattern obtained by cutting a piece of corrugated paper P into a predetermined shape. Such a packaging box B is assembled into a rectangular parallelepiped shape, for example, by folding one piece of corrugated paper P along a fold line L, and has a bottom portion 1, one side portion facing each other 2, and another side portion facing each other. It comprises a side part 3 and a lid part 4. The first inner flaps e and f, which are continuously provided via folds L and form the bottom 1, are provided at the lower portions of the two side surfaces a, b forming one side 2, and the other side. At the lower part of each of the two side surfaces c and d constituting the part 3, first outer flaps g and h which are continuously provided via a fold L and constitute the bottom part 1 are provided. A second inner flap i, j is provided at the upper part of the two side faces a, b, which are connected to each other through a fold L, and constitutes the cover part 4, and the other side part 3, which constitutes the other side part 3, is formed. The second outer flaps k and l which are continuously provided through the folds L and constitute the lid 4 are provided on the upper portions of the side surfaces c and d of the sheets. In this conventional packaging box B, the side portions 2 and 3 are bent at folds, and the edge y provided at the end of the side surface c is bonded to the back surface of the side surface b to form a cylindrical shape. The inner flaps e and f are folded to the side 2 side, and the first outer flaps g and h are folded so as to cover the inner flaps e and f to form the bottom 1 and fixed with an adhesive tape or staple to form a box. You. When this conventional packaging box B is used, for example, as a packaging box B for holding two watermelons, a packaging corresponding to the size of the watermelon is prepared. The sizes of watermelons are generally M, L, 2L, 3L, 4L, and 5L, so the packaging box B is available in M, L, 2L, 3L, 4L, and 5L according to the size of the watermelon. When packing watermelons in packaging box B, the watermelons were wrapped in shock-absorbing material or corrugated paper was sandwiched between watermelons to prevent watermelons from contacting each other during transportation. .

[0003]

[Problems to be solved by the invention]

 By the way, the conventional packaging box B is formed by assembling one piece of corrugated paper P itself. However, when packaging a plurality of perishable contents such as watermelon, a separate shock absorbing material or corrugated cardboard is required. A spacer having a shock-absorbing capacity such as paper must be prepared, and there is a problem that the assembling work at the time of packaging becomes complicated. Also, there is a problem that the number of parts is increased by the spacer and the number of packaging elements is increased accordingly. Further, since the spacer is a member separate from the packaging box B, it is easy to move. Therefore, there is a problem that the center of gravity of the packaging box B is apt to change and the holding stability of the contents in the packaging box B is poor.

[0004] The present invention has been made in view of such a problem, and a packaging box which facilitates an assembling operation, reduces the number of parts, and improves the holding stability of contents. The purpose is to provide.

[0005]

[Means for Solving the Problems]

 The technical means of the present invention for solving such a problem is as follows. One corrugated paperboard is folded along a fold to form a rectangular parallelepiped, and has a bottom portion, one side portion facing each other, and a portion facing each other. A first inner flap having a second side, a lid, and a lower portion of each of the two side surfaces forming the one side portion, the first inner flap being connected to each lower portion through a fold and forming a bottom portion; A first outer flap, which is connected to each lower part of the two side surfaces forming a portion through a fold and forms a bottom portion, and the two side surfaces forming one of the one and the other side portions A second inner flap connected to the upper part of the upper part through a fold and forming a lid part; and a second inner flap forming one of the one and the other side parts through a fold at the upper part. And a second outer flap which is continuously provided and constitutes a lid portion. The least one each of the lower also the flap and the first outer flap, and a partition portion that is brought into surface contact with each other are folded inside a structure which is continuously provided through the crease. Since a partitioning part is provided in advance on a piece of corrugated cardboard in advance, a packaging box having a partition inside can be easily assembled by folding work, so that the assembling work can be easily performed. it can. Also, since the number of parts required for the packaging box is only one pattern, the number of parts can be minimized. The smaller the number of parts, the easier the assembly of the packaging box. Further, since the inside of the packaging box is divided (two sections) by the partition section, the contents can be sorted for each section. For example, when two watermelons are placed in a packaging box, the watermelons are separated by a partition provided continuously with the packaging box, and the partition is made of cardboard paper. Watermelon is less likely to be damaged due to increased shock absorption. In addition, since the partition is connected to the lid and the bottom of the partition is fixed, the holding stability of the contents is improved.

Further, if necessary, the first inner flap is divided into two parts, and the lower part of each of the divided first inner flaps is folded inward at each lower part through a crease through a crease. The first outer flap is provided with partitioning portions which are folded back inside and are in contact with each other at the lower portion of the first outer flap. Since the number of packaging boxes divided by the partitioning part is increased (four divisions), the number of sorting can be increased.

[0007] Furthermore, if necessary, the partition portion is provided with a tongue-like folded piece that is folded back into a section partitioned by the partition portion and can contact the contents. The folded piece reduces the width of the partitioned section from which the folded piece protrudes. For example, if the size of the watermelon is slightly smaller than the partitioned section, the folded pieces can be folded back and brought into contact with the watermelon to stably hold the watermelon in the section so as not to move.

Further, if necessary, the outer periphery of the folded piece is formed in an arc shape. Since a sufficient contact area for the contents can be ensured with a small area, the air space generated in the partition by folding back can be reduced, and a decrease in the strength of the folded portion can be suppressed.

In addition, one corrugated paperboard is folded along a fold to form a rectangular parallelepiped, and includes a bottom, one side facing each other, the other side facing each other, and a lid. A first inner flap, which is connected to each lower part of the two side surfaces forming one side part through a fold and forms a bottom part, and a lower part of each of the two side surfaces forming the other side part, A first outer flap, which is continuous through a fold and forms a bottom, and an upper part of two side surfaces, which constitute one of the one and the other sides, are formed through a fold. The second inner flap forming the lid and the second outer flap forming the lid and connected to the upper portion of the two side surfaces forming one of the one and the other sides through a fold. A packaging box provided with a flap, wherein the first inner flap and the first outer flap have a small number. At least one of the lower portions is provided with a partition portion which is folded back inside and is brought into contact with each other via a fold line, and the contents are folded back to the partition portion in the section partitioned by the partition portion. A tongue-shaped folded piece that can be brought into contact with the tongue is provided with its outer periphery formed in an arc shape. Since a partitioning portion is provided in advance on a piece of corrugated cardboard, a packaging box having a partition therein can be easily assembled by bending, so that the assembling operation can be easily performed. Also, since the number of parts required for the packaging box is only one pattern, the number of parts can be minimized. The smaller the number of parts, the easier the assembly of the packaging box. Further, since the inside of the packaging box is divided (two sections) by the partition section, the contents can be sorted for each section. For example, when two watermelons are placed in a packaging box, the watermelons are separated by a partition provided continuously with the packaging box, and the partition is made of cardboard paper. Watermelon is less likely to be damaged due to increased shock absorption. In addition, since the partition is connected to the lid and the bottom of the partition is fixed, the holding stability of the contents is improved. The folded piece reduces the width of the partitioned section from which the folded piece protrudes. For example, if the size of the watermelon is slightly smaller than the partitioned section, the folded pieces can be folded back and brought into contact with the watermelon to stably hold the watermelon in the section so as not to move. Since a sufficient contact area with the contents can be ensured in a small area, the air space generated in the partition by folding back can be reduced, and the strength of the folded back can be suppressed.

[0010] Furthermore, one piece of corrugated cardboard is folded along the fold to form a rectangular parallelepiped, and has a bottom, one side facing each other, the other side facing each other, and a lid. A first inner flap, which is connected to each lower part of the two side surfaces forming one side part through a fold and forms a bottom part, and a lower part of each of the two side surfaces forming the other side part, A first outer flap, which is continuous through a fold and forms a bottom, and an upper part of two side surfaces, which constitute one of the one and the other sides, are formed through a fold. The second inner flap forming the lid and the second outer flap forming the lid and connected to the upper portion of the two side surfaces forming one of the one and the other sides through a fold. In a packaging box provided with a flap, the first inner flap is divided into two, Partitions that are folded back inside and are in contact with each other at the lower portions of the first inner flaps are connected to each other via folds, and that are folded back into each lower portion of the first outer flap and are in contact with each other. The tongue-shaped folded piece that is folded back into a section partitioned by the partition and that can abut on the contents is formed in an arc shape on the outer circumference of the partition. The configuration was provided. Since a partitioning portion is provided in advance on a piece of corrugated cardboard, a packaging box having a partition therein can be easily assembled by bending, so that the assembling operation can be easily performed. Also, since the number of parts required for the packaging box is only one pattern, the number of parts can be minimized. The smaller the number of parts, the easier the assembly of the packaging box. Further, since the inside of the packaging box is divided (four divisions) by the partition part, the number of divisions can be increased. In addition, since the partition is connected to the lid and the bottom of the partition is fixed, the holding stability of the contents is improved. The folded piece reduces the width of the partitioned section from which the folded piece protrudes. For example, if the size of the watermelon is slightly smaller than the partitioned section, the folded pieces can be folded back and brought into contact with the watermelon to stably hold the watermelon in the section so as not to move. Since a sufficient contact area with the contents can be ensured in a small area, the air space generated in the partition by folding back can be reduced, and the strength of the folded back can be suppressed.

[Embodiment of the invention]

 Hereinafter, a packaging box according to an embodiment of the present invention will be described with reference to the accompanying drawings. Note that the same components as described above are denoted by the same reference numerals and described. As shown in FIGS. 1 to 3, the packaging box B is assembled into a rectangular parallelepiped by folding one piece of corrugated paper P along a fold line L. The packaging box B includes a bottom portion 1, one side portion 2 facing each other, another side portion 3 facing each other 3, a lid portion 4, and a partition portion 5. The corrugated paper P is die-cut so that the streaks are formed vertically on the side portions 2 and 3 having a large area. The bottom portion 1 forms first inner flaps e and f which are continuously provided via folds L at lower portions of two side surfaces a and b constituting one side portion 2 and the other side portion 3. The first outer flaps g and h which are continuously provided at the lower portions of the two side surfaces c and d through the fold L and constitute the bottom portion 1 are formed. The first inner flaps e and f are each divided into two with a cut at the center. The inner flaps e and f are folded back and joined at the bottom center to be flush. The outer flaps g and h are further folded back from the outside to the flushed inner flaps e and f, cover the inner flaps e and f, and are joined flush at the bottom center. That is, the bottom 1 has a two-layer structure of a layer composed of the inner flaps e and f and a layer composed of the outer flaps g and h. On the side surfaces a and b constituting one side portion 2, a handle hole x used as a handle when carrying the packaging box B is provided. Further, an edge y is provided at the side end of the side surface c to bend the side portions 2 and 3 into a cylindrical shape so as to adhere to the back surface of the side end of the side surface b. The lid part 4 is composed of a second inner flap i, j continuously provided via a fold L on the upper part of each of two side surfaces a, b constituting one side part 2 and the other side part 3. The second outer flaps k and l are provided at the upper portions of the two side faces c and d via a fold L.

The partitioning section 5 includes partitioning faces m and n which are continuously provided at the lower portions of the first inner flaps e and f via the fold line L and are folded back to be in contact with each other. A partition surface m ', n' is provided at the lower portion of each of the outer flaps g, h via a fold line L, is folded inside, and is in contact with each other. The partition surfaces m and n are folded back into the side portions 2 and 3 when the inner flaps e and f are bent to be flush. The folded partition surfaces m and n are faced and overlapped. The stacked partition surfaces m and n divide the inside of the packaging box B into two sections. When the outer flaps g and h are folded to be flush with each other, the partition surfaces m 'and n' are folded into the side portions 2 and 3 from the cuts of the inner flaps e and f. The folded partition surfaces m 'and n' are face-to-face and overlapped. The overlapping partition surfaces m 'and n' further divide the inside of the packaging box B into two sections. That is, the inside of the packaging box B is divided into four sections by the partitioning portion 5 including the partitioning surfaces m, n, m ', and n'. The partition surfaces m, n, m ', and n' are provided with a plurality of tongue-shaped folded pieces z that can be folded toward the partitioned section and contact the contents. The folded piece z has an arc-shaped outer periphery, and is formed at a partition surface m, n, m ', n' corresponding to the outer periphery of the folded piece z so that a part of the arc is folded and folded back to the section side. Is notched. When the folded piece z is folded back to the partition side, the folded piece z comes into contact with the content and the content is held inside. For example, as shown in Fig. 3 (1), when the volume of the partitioned compartment is larger than the occupied volume of the watermelon, the watermelon simply placed in the packaging box B may have a reduced holding stability in the compartment. Chip. However, as shown in FIG. 3B, if the folded piece z is folded, the folded piece comes into contact with the side of the watermelon, so that the watermelon is stably held in the packaging box B.

The packaging box B according to this embodiment is assembled as follows. First, the side surfaces a, b, c, and d were bent along the fold line L to form the side portions 2, 3. At that time, the edge y of the side surface c was bonded to the back surface of the side end of the side surface b with an adhesive. Next, the internal flaps e and f are bent along the fold line L and the partition surfaces m and n are also bent along the fold line L. f was joined flush to form a partition 5. Subsequently, the outer flaps g and h are bent along the fold line L, and the partition surfaces m ′ and n ′ are also bent along the fold line L. Then, the inner flaps g and h were joined to be flush with each other and overlapped with the inner flaps e and f to form the partition 5. In order to fix the assembled bottom part 1, the outer flaps g and h were fixed to the side parts 2 and 3 with an adhesive tape. In the packaging box B assembled in this manner, the contents can be sorted into four sections by the partition section 5. Also, when packaging perishable items such as fruits, they can be divided into compartments separated by the partitioning section 5 and packaged. Can be. At this time, since the folded portion z is provided in the partitioning portion 5, the content can be stably maintained by folding the folded portion z and abutting the fruit. Further, since the partition part 5 is superposed to form a two-layer structure, it is excellent in shock absorption. Further, the packaging box B is excellent in load resistance and shock absorption because the bottom portion 1 has a two-layer structure of corrugated paper.

In the packaging box according to the above-described embodiment, the folded piece z is provided only on the partitioning portion 5. Can be increased. Further, in the packaging box according to the above embodiment, the first inner flaps e and f are divided into two, but the same effect can be obtained by dividing the first outer flaps g and h into two. .

Next, a packaging box according to another embodiment of the present invention will be described. The same components as described above will be described with the same reference numerals. As shown in FIGS. 4 and 5, in the packaging box B, the first inner flaps e and f are not divided into two parts, but are respectively installed in the lower portions of the first inner flaps e and f. The partition surfaces m and n that are folded back and come into contact with each other are continuously provided via the fold line L, and the partition surfaces m ′ and n ′ are not provided on the first outer flap. According to the packaging box B, as shown in FIG. 5, the interior of the packaging box B is partitioned into two sections by the partitioning portion 5. According to the packaging box B, the same effect as that of the packaging box B divided into four sections described above can be obtained.
