As described above, the box body forming piece 16 is composed of the outer box forming portion 18 and the partition forming portion 20, and the outer box forming portion 18 and the partition forming portion 20 are the first inner surface plate 36 and the lower horizontal plate 90. The ends are continuously integrated.

Next, an example of an assembling method of the packaging box 10 with a cushioning partition will be described. Here, regarding the folding method of each folding ruled line of the box body forming piece 16 shown in FIG. 2, the folding method in which the front surface is convex is referred to as normal folding, and the folding method in which the back surface is convex is referred to as reverse folding.

First, as shown in FIG. 3A, the folding ruled line 108 is folded forward and the auxiliary horizontal plate 98 and the auxiliary movable vertical plate 100 are overlapped on the back surface side of the upper horizontal plate 94 and the fixed vertical plate 96. Glue 118 is applied to the surface of 100. Then, as shown in FIG. 3B, the folding ruled line 104 is folded forward and the auxiliary horizontal plate 98 and the auxiliary movable vertical plate 100 are overlapped on the back surface side of the lower horizontal plate 90 and the movable vertical plate 92, and the auxiliary movable vertical plate is overlapped. 100 is glued to the movable vertical plate 92.

Further, after applying the glue 120 to the surface of the fixed vertical plate 96, as shown in FIG. 4A, the upper horizontal plate 94 and the fixed vertical plate 96 are formed into the first inner surface plate by folding the folded ruled line 112 forward. The fixed vertical plate 96 is laminated on the back surface side of the 36 and glued to the first inner surface plate 36. As a result, each member of the partition forming portion 20 is folded on the back surface side of the first inner surface plate 36. Then, the second inner surface plate 62 is folded forward along the fold ruled line 64, and the second inner surface plate 62 is overlapped with the back surface side of the third side surface plate 26.

After that, as shown in FIG. 4B, each member of the partition forming portion 20 and the first inner surface plate 36 are overlapped on the back surface side of the fourth side plate 28 by folding the fold ruled line 38 forward, and the first The glue 122 is applied to the surface of the inner surface plate 36 of the above. Then, as shown in FIG. 5, by folding the fold ruled line 32 forward, the first and second side surface plates 22, 24 are overlapped on the surface side of the first and second inner surface plates 36, 62, and the first The side plate 22 is glued to the first inner plate 36. The box body forming piece 16 is shipped from a factory or the like that manufactures a packaging box 10 with a cushioning partition in this folded state.

Next, in a factory or the like for packaging the contents S, the box body forming piece 16 is made three-dimensional. First, the fold ruled lines 30, 32, 34, 38 are folded forward at 90 degrees, respectively, and a quadrangular cylinder composed of four side plates 22, 24, 26, 28 and the first and second inner plates 36, 62. Form body 124. After that, in order to close the bottom end of the cylinder 124, the side flaps 58 and 82 are properly folded at 90 degrees at the folded ruled lines 60 and 84, and the first bottom piece 48 is positively folded at 90 degrees at the folded ruled line 50. Fold it and stack it on the side flaps 58 and 82. Then, after applying the glue 126 to the surface of the first bottom piece 48, the second bottom piece 72 is folded forward at 90 degrees and overlapped with the first bottom piece 48, and the tip end side region 72b of the second bottom piece 72 is formed. Glue to one bottom piece 48. As a result, the bottom 128 of the seal end type is formed, and the states shown in FIGS. 6 (a) to 6 (d) and 7 (a) are obtained.

To briefly explain this state, as shown in FIG. 6D, in the bottom 128, the first and second bottom pieces 48 and 72 are glued to each other, and the auxiliary crease line 52 of the first bottom piece 48 is second. It almost overlaps with the dismantling break line 76 of the bottom piece 72. Further, as shown in FIG. 7A, the second inner surface plate 62 overlaps with the inner surface side of the third side surface plate 26, and the opening portion 70 and the opening breaking line 68 of the third side surface plate 26 are through holes. It fits inside the 66 and the upper end of the cushioning piece 86 projects from the lid-side end of the cylinder 124. Each member of the partition forming portion 20 is folded against each other and arranged on the inner surface side of the first inner surface plate 36, and a part of the movable vertical plate 92 and the upper horizontal plate 94 protrudes from the end portion of the tubular body 124 on the lid side. ..

Next, in order to make the partition forming portion 20 three-dimensional, the end portion (near the folded ruled line 104) of the upper horizontal plate 94 is pushed in the direction of the bottom portion 128. At this time, since an elastic force for maintaining the folded state is generated in each folded ruled line of the partition forming portion 20, the elastic force is pushed against the elastic force.

When the end portion of the upper horizontal plate 94 (near the folded ruled line 104) is pushed in, as shown in FIG. 7B, the fixed vertical plate 96 is glued to the inner surface of the first inner surface plate 36, so that the movable vertical plate 96 is movable. The plate 92 moves and faces the vicinity of the third side plate 26, and the engaging portion 114 escapes from the movable vertical plate 92, becomes flush with the lower horizontal plate 90, and protrudes toward the third side plate 26. When each folded ruled line of the partition forming portion 20 is bent at approximately 90 degrees, the engaging portion 114 engages with the engaging receiving portion 62a of the second inner surface plate 62. Further, the support leg piece 116 escapes from the lower horizontal plate 90 and is flush with the movable vertical plate 92 so as to project toward the bottom 128, and the tip portion of the support leg piece 116 is the inner surface of the bottom 128 (side flaps 58, 82). Locked to. Then, the lower horizontal plate 90 is arranged above the bottom portion 128 with both ends supported by the first inner surface plate 36 and the movable vertical plate 92, and the upper horizontal plate 94 is placed on the fixed vertical plate 96 and the movable vertical plate 92. Both ends are supported and arranged above the lower horizontal plate 90. Further, since the auxiliary movable vertical plate 100 is glued to the inner surface of the movable vertical plate 92, both ends of the auxiliary horizontal plate 98 are supported by the fixed vertical plate 96 and the auxiliary movable vertical plate 100, and the upper horizontal plate 94 and the lower side are supported. It is arranged between the horizontal plate 90 and the horizontal plate 90. As a result, the three-dimensional buffer partition 14 is formed, so that the operation of pushing the upper horizontal plate 94 is stopped.

When the operation of pushing the upper horizontal plate 94 is stopped, the cushioning partition 14 tries to return to the folded state by the elastic force generated in each folding ruled line, but the engaging portion 114 engages with the engaging receiving portion 62a. Therefore, it is maintained in an appropriate three-dimensional shape.

Next, as shown in FIG. 8A, the inclusion S is inserted into the cylinder 124 from the end on the lid side and supported by the cushioning partition 14. The lower part of the inclusion S is supported by the upper surface of the lower horizontal plate 90, the upper position of the side surface is guided by the inner peripheral edge portion of the through hole 94a of the upper horizontal plate 94, and the position slightly lower than the center of the side surface is assisted. It is guided by the inner peripheral edge of the through hole 98a of the horizontal plate 98.

When the container S is inserted, the side flaps 54 and 78 are folded forward at 90 degrees at the second and third fold ruled lines 56 and 80 in order to close the end portion of the cylinder 124 on the lid side. Then, after applying the glue 130 to the surface of the insertion piece 44, the folding ruled line 46 is folded forward at 90 degrees to tilt the insertion piece 44, and the lid piece 40 is normally folded along the first folding ruled line 42 to form the side flap 54. , 80. As a result, the cushioning piece 86 is pushed by the lid piece 40 and automatically bent at the fourth fold ruled line 88.

Then, the end portion of the tubular body 124 is closed with the lid piece 40, the insertion piece 44 is inserted into the gap between the side flaps 54 and 78 and the second inner surface plate 62 and the third side surface plate 26, and the insertion piece 44 is transparent. It is glued to the back surface of the opening portion 70 through the hole 66. As a result, the lid portion 132 in which the lid piece 40, the cushioning piece 86, and the side flaps 54 and 78 are sequentially overlapped is formed, and the assembled state shown in FIGS. 8 (b) and 1 (a) and 1 (b) is obtained.

In this assembled state, the cushioning piece 86 is bent diagonally at the fourth folding ruled line 88, and the tip end portion is locked to the inner surface of the lid piece 40 and fits in the tubular body 124. The side flaps 54 and 78 are bent at the second and third fold ruled lines 56 and 78, pushed by the inner surface of the cushioning piece 86 and arranged diagonally downward, and are used for cushioning between the lid piece 40 and the cushioning piece 86. A space is formed and the upper part of the inclusion S is buffered by the side flaps 54, 78 and the buffer piece 86.

When opening the lid 132 of the packaging box 10 with a cushioning partition, the opening 70 of the third side plate 26 is pushed in with a finger to break the opening breaking line 68, and the lid piece 40 and the insertion piece 44 are picked up. Then pull it up. At this time, the opening portion 70 is separated from the third side plate 26, but is glued to the insertion piece 44 and moves together, so that it does not become dust. Then, as shown in FIG. 8A, when the cushioning piece 86 and the side flaps 54 and 78 are pulled up to open the end portion of the tubular body 124, the contained object S inside can be taken out.

When resealing after opening, the side flaps 54, 78, the cushioning piece 86, and the lid piece 40 may be tilted in order, and the insertion piece 44 may be inserted into the inner surface side of the second inner surface plate 62.

When the packaging box 10 with a cushioning partition is discarded after use, the three-dimensional packaging box 10 with a cushioning partition is made foldable. First, the central portion of the second bottom piece 72 is pushed with a finger to break the dismantling break line 76, the tip end side region 72b is separated from the second bottom piece 72 (base end side region 72a), and the bottom portion 128 is dismantled. .. At this time, the separated tip side region 72b is glued to the first bottom piece 48 and moves together, so that it does not become dust. Further, since the auxiliary crease line 52 overlapping the dismantling break line 76 is provided inside the first bottom piece 48, both corners of the first bottom piece 48 are appropriately bent and the dismantling break line 76 is smoothly broken. Can be made to.

When the bottom portion 128 is disassembled, the first bottom piece 48 and the tip side region 72b are further pushed deeply, and the lower surface of the lower horizontal plate 90 is pushed up by the inner surface of the first bottom piece 48 (or the inner surface of the side flaps 58 and 82 (not shown)). Then, as shown in FIG. 9B, the engagement between the engaging portion 114 and the engaging receiving portion 62a is released, and the three-dimensional cushioning partition portion 14 can be returned to the original folded state. Dismantling the bottom 128 and folding the cushioning partition 14 can be easily done in almost one action. Then, by putting the cylinder 124 in a flat folded state, the packaging box 10 with a cushioning function can be compactly disposed of.

As described above, the packaging box 10 with a buffer partition has a simple structure composed of one box body forming piece 18, and when the container S is set in the buffer partition 14, the lower portion of the container S becomes. Supported by the upper surface of the lower horizontal plate 90, the side surface of the inclusion S is guided by the inner peripheral edges of the through holes 94a, 98a of the upper horizontal plate 94 and the auxiliary horizontal plate 98, and the upper portion of the inclusion S is the side flaps 54, 78. And protected by the buffer piece 86, the contents S are safely held so as not to come into contact with the outer box 12.

Further, by engaging the engaging portion 114 of the cushioning partition 14 with the engaging receiving portion 62a inside the outer box 12, the operation of the cushioning partition 14 to return to the folded state is prevented, and the cushioning partition 14 is prevented from returning to the folded state. Can be held in an appropriate three-dimensional shape. Moreover, by making the cushioning partition 14 in the folded state three-dimensional at the time of assembly, the engaging portion 114 can be automatically and smoothly engaged with the engaging receiving portion 62a, which is very easy to assemble. Further, the cushioning structure of the lid portion 132 does not require any special work such as gluing, and is automatically formed during the work of closing the end portion on the lid side with the lid portion 132, so that it is very assembled. Cheap. In addition, after use, the work of folding and disposing of the packaging box 10 with a cushioning partition is also easy.

Next, a second embodiment of the packaging box with a buffer partition of the present invention will be described with reference to FIGS. 10 and 11. Here, the same configuration as the above-mentioned packaging box 10 with a partition for cushioning (and the box body forming piece 16) is designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 10A, the packaging box 134 with a cushioning partition of this embodiment is composed of a substantially rectangular parallelepiped outer box 12 and a cushioning partition 14 arranged in the outer box 12. As shown in 10 (b), it is used as a packaging box for packaging two containers S each. That is, the packaging box 10 with a buffer partition containing one piece is modified into a packaging box containing two pieces.

The packaging box 134 with a partition for cushioning is formed by assembling a single box body forming piece 136 made of cardboard or the like, and the box body forming piece 136 is an outer box assembled to the outer box 12 as shown in FIG. It is composed of a forming portion 138 and a partition forming portion 140 assembled on the cushioning partition 14.

The structure of the box body forming piece 136 is almost the same as that of the box body forming piece 16 described above, but the size of the plurality of plates is increased in order to include two pieces, and the upper horizontal plate 94 and the auxiliary horizontal plate are used. The difference is that two through holes 94a and 98a of the plate 98 are formed.

The method of assembling the packaging box 134 with a cushioning partition, the operation of opening and resealing the lid 132, and the operation at the time of disposal are the same as the above-mentioned packaging box 10 with a cushioning partition. Also in this packaging box 134 with a cushioning partition, substantially the same effect as that of the above-mentioned packaging box 10 with a cushioning partition can be obtained.

Next, a third embodiment of the packaging box with a buffer partition of the present invention will be described with reference to FIGS. 12 to 14. Here, the same configuration as the above-mentioned packaging box 10 with a partition for cushioning (and the box body forming piece 16) is designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 12A, the packaging box 142 with a cushioning partition of this embodiment is composed of a substantially rectangular parallelepiped outer box 12 and a cushioning partition 14 arranged in the outer box 12. As shown in 12 (b), it is used as a packaging box for packaging five containers S at a time. That is, the packaging box 10 with a buffer partition containing one piece is modified into a packaging box containing five pieces.

The packaging box 142 with a partition for cushioning is formed by assembling a single box body forming piece 144 made of cardboard or the like, and the box body forming piece 144 is an outer box assembled to the outer box 12 as shown in FIG. It is composed of a forming portion 146 and a partition forming portion 148 assembled on the cushioning partition 14.

The structure of the box body forming piece 144 has much in common with the above-mentioned box body forming piece 16, but the size of a plurality of plates is increased in order to contain 5 pieces, and the upper horizontal plate 94 and the auxiliary horizontal plate are used. The difference is that five through holes 94a and 98a of the plate 98 are formed. Further, a point where an engaging receiving portion 62b made of a substantially rhombic through hole is provided inside the second inner surface plate 62, and an engaging portion 150 engaging with the engaging receiving portion 62b are movable vertical plates. The difference is that they are provided not at the boundary between the 92 and the lower horizontal plate 90 but at the boundary between the movable vertical plate 92 and the upper horizontal plate 94.

The method of assembling the packaging box 134 with a cushioning partition is basically the same as the above-mentioned packaging box 10 with a cushioning partition. However, since the configurations of the engaging portion 150 and the engaging receiving portion 62b have been changed, the operation when they are engaged is slightly different.

FIG. 14A shows a state in which the tubular body 124 is three-dimensionally formed to form the bottom 128 while the packaging box 134 with the cushioning partition (box body forming piece 144) is being assembled. In this state, each member of the partition forming portion 148 in the cylinder 124 is folded against each other and arranged on the inner surface side of the first inner surface plate 36, and a part of the movable vertical plate 92 and the upper horizontal plate 94 is a cylinder. It protrudes from the end of 124 on the lid side. This is almost the same as the state of the packaging box 10 with a cushioning partition (box body forming piece 16) shown in FIG. 7 (a).

From this state, in order to make the partition forming portion 148 three-dimensional, when the end portion (near the folded ruled line 104) of the upper horizontal plate 94 is pushed in the direction of the bottom portion 128, as shown in FIG. The plate 92 moves and faces the vicinity of the third side plate 26, and the engaging portion 150 that has come out of the movable vertical plate 92 is flush with the upper horizontal plate 94 and protrudes toward the third side plate 26. When each folded ruled line of the partition forming portion 148 is bent at approximately 90 degrees, the engaging portion 150 enters and engages with the engaging receiving portion 62b of the second inner surface plate 62. As a result, the three-dimensional cushioning partition 14 is formed, so that the pushing of the upper horizontal plate 94 is stopped.

When the operation of pushing the end portion of the upper horizontal plate 94 is stopped, the cushioning partition 14 tries to return to the folded state by the elastic force of each folding ruled line, but the engaging portion 150 enters the engaging receiving portion 62b. Since they are engaged with each other, they are held in an appropriate three-dimensional shape.

Further, in the assembled state in which the five containers S are packaged, the cushioning piece 86 is bent diagonally at the fourth folding ruled line 88, and the tip portion is locked to the inner surface of the lid piece 40 and is contained in the cylinder 124. It fits. The side flaps 54 and 78 are bent at the second and third fold ruled lines 56 and 78, pushed by the inner surface of the cushioning piece 86 and arranged diagonally downward, and are used for cushioning between the lid piece 40 and the cushioning piece 86. Space is formed. Two of the five inclusions S at both ends are buffered at the top by the side flaps 54, 78 and the buffer piece 86, and the other three are buffered at the top by the buffer piece 86. Protected by.

The method of opening and resealing the lid 132 of the packaging box 142 with a cushioning partition and the work at the time of disposal are the same as those of the packaging box 10 with a cushioning partition. Also in this packaging box 142 with a cushioning partition, the same function and effect as the above-mentioned packaging box 10 with a cushioning partition can be obtained.

The packaging box with a buffer partition of the present invention is not limited to the above embodiment. For example, the engaging portion provided in the partition forming portion and the engaging receiving portion provided in the second inner surface plate form the cushioning partition portion three-dimensionally (the upper horizontal plate protruding from the end portion on the lid side of the cylinder). It suffices as long as it engages with each other by pushing the end portion toward the bottom), and the individual shapes, sizes, number of sets and arrangement can be appropriately changed.

The auxiliary horizontal plate and the auxiliary movable plate of the cushioning partition are provided to prevent the contained object from tilting in the cushioning partition, and may be omitted if necessary. Further, the support leg piece is provided to prevent the lower horizontal plate from tilting downward due to the mass of the contained object when the contained object is set in the cushioning partition, and the cushioning partition is provided. If the contents can be supported by the elastic force to return to the folded state, the support leg pieces can be omitted.

In addition, the opening portion (and the opening breaking line) of the third side plate can be omitted if not necessary. In that case, since it is not necessary to prevent the second inner surface plate from overlapping the opened portion, the configuration such as the through hole 66 described above can be omitted. Further, the size of the outer box and the partition for cushioning, the material of the box body forming piece, and the like can be freely set according to the application.
