The present disclosure may include all combinations of configurations that can be combined among the configurations described in the following embodiments.

Embodiment 1 FIG.
FIG. 1 is a schematic cross-sectional side view showing a packaging device 1 according to the first embodiment. As shown in FIG. 1, the packaging device 1 includes a box 2, a structure 3, a bottom buffer member 4, and a receiving member 5. The box 2 stores a product 90 that is to be packed. The box 2 may be made of cardboard, for example. The product 90 may be any product such as a home appliance or a commercial electric device.

  The structure 3, the bottom buffer member 4, and the receiving member 5 are disposed inside the box 2. Each of the structure 3, the bottom buffer member 4, and the receiving member 5 may be made of resin or paper.

  The bottom buffer member 4 is disposed at the bottom of the box 2. The bottom buffer member 4 holds the bottom of the product 90. The receiving member 5 is placed on the upper surface of the product 90. The lower end of the structure 3 is in contact with the receiving member 5. The upper end of the structure 3 is in contact with the top of the inner surface of the box 2. In the present embodiment, the following effects can be obtained by providing the structure 3. Since the structure 3 is in contact with the top of the inner surface of the box 2, when a load acts on the top of the packaging device 1, the structure 3 can bear a part of the load. For this reason, even when a plurality of packing devices 1 are stacked and placed at the time of distribution or warehouse storage, the box 2 and the structure 3 can be reliably prevented from being crushed. It can be reliably suppressed. Further, even when repeated vibrations and shocks are applied during transportation, the product 90 can be prevented from shaking up and down inside the box 2, and the product 90 can be securely held in the box 2. Can do. For this reason, it is possible to reliably suppress the occurrence of rubbing in the product 90 and the occurrence of physical distribution defects such as crushing deformation of the structure 3, the bottom cushioning member 4, and the receiving member 5.

  FIG. 2 is a perspective view of the structure 3 included in the packaging device 1 according to the first embodiment. The structure 3 is formed of a sheet material. The sheet material may be, for example, any one of a paper cardboard sheet, a resin cardboard sheet, and cardboard. The sheet material forming the structure 3 has a first surface 6, a second surface 7, and a third surface 8. The first surface 6 has a wall surface portion 6a and a bendable portion 6b. The second surface 7 includes a wall surface portion 7a and a bendable portion 7b. The third surface 8 has a wall surface portion 8a and a bendable portion 8b. Each of the foldable parts 6b, 7b, 8b has a plurality of foldable lines 9 in parallel. The bendable parts 6b, 7b, 8b can be bent by at least one bendable line 9. FIG. 3 shows a state where none of the bendable lines 9 is bent. The bendable line 9 may be, for example, a line processed so as to be recessed in a groove shape or a line processed like a perforation. In the illustrated example, six parallel bendable lines 9 are provided.

  The wall surface portion 7 a of the second surface 7 is bent and connected to the wall surface portion 6 a of the first surface 6 via the first fold line 10. The wall surface portion 7a is substantially perpendicular to the wall surface portion 6a. The wall surface portion 8 a of the third surface 8 is bent and connected to the wall surface portion 7 a of the second surface 7 via the second fold line 11. The second fold line 11 is parallel to the first fold line 10. The wall surface portion 8a is substantially perpendicular to the wall surface portion 7a. The plurality of foldable lines 9 extend in a direction perpendicular to the first fold line 10 and the second fold line 11. The foldable lines 9 of the foldable portions 6 b, 7 b, 8 b are at the same position with respect to the positions in the direction parallel to the first fold line 10 and the second fold line 11.

  FIG. 3 is a perspective view of the structure 3 included in the packaging device 1 according to the first embodiment. In the following description, the dimension of the structure 3 in the direction parallel to the first fold line 10 and the second fold line 11 is referred to as “the height of the structure body 3”. The height of the structure 3 can be changed by folding the bendable portions 6b, 7b, 8b with at least one bendable line 9. FIG. 3 shows a state in which the foldable portions 6b, 7b, and 8b are bent by one foldable line 9 farthest from the wall surface portions 6a, 7a, and 8a among the plurality of parallel foldable lines 9. In the following description, the bent line among the bendable lines 9 is referred to as a “bend line 12”. In the present embodiment, the height of the structure 3 can be changed by selecting a line to be bent from among the plurality of bendable lines 9. That is, the height of the structure 3 can be lowered as the position of the bending line 12 is closer to the wall surfaces 6a, 7a, and 8a.

  According to the present embodiment, the height of the structure 3 can be changed according to the height of the product 90, so that one type of structure 3 can correspond to a plurality of types of products 90. Thereby, versatility becomes favorable and productivity can be improved.

  The structure 3 may be used in a state where the bendable line 9 is not bent, that is, in the state shown in FIG. In the present embodiment, by providing six parallel bendable lines 9, the height of the structure 3 can be changed in seven stages. If it is this Embodiment, the structure 3 is provided with three surfaces, the 1st surface 6, the 2nd surface 7, and the 3rd surface 8, When a load acts on the structure 3, a structure It can prevent more reliably that each surface of 3 falls down. For this reason, crushing of the box 2 and the structure 3 can be prevented more reliably. That is, the compression resistance of the packing apparatus 1 in the stacking in a warehouse etc. improves.

  In the present embodiment, the direction in which the first surface 6 projects from the first fold 10 and the direction in which the third surface 8 projects from the second fold 11 are opposite directions. Thereby, since the fall of the 2nd surface 7 in a center can be prevented more reliably, the load resistance of the structure 3 can further be improved. When viewed from a direction parallel to the first fold line 10 and the second fold line 11, the structure 3 is bent in a crank shape.

  As shown in FIG. 3, the bendable portion 6b has a first bent piece 6c extending from the bend line 12 in a direction perpendicular to the wall surface portion 6a. The foldable portion 7b has a second bent piece 7c extending from the fold line 12 in a direction perpendicular to the wall surface portion 7a. The foldable portion 8b has a third fold piece 8c extending from the fold line 12 in a direction perpendicular to the wall surface portion 8a. In the state where the structure 3 shown in FIG. 3 is arranged in the box 2, the first bent piece 6 c, the second bent piece 7 c, and the third bent piece 8 c are in contact with the top of the inner surface of the box 2. Thus, in the state where the first bent piece 6c, the second bent piece 7c, and the third bent piece 8c are formed, the contact area with the top of the inner surface of the box 2 increases, so that the load resistance of the structure 3 is further increased. It can be improved.

  Although illustration is omitted, when the first bent piece 6 c and the second bent piece 7 c are formed, the structure 3 may not include the third surface 8. When the first bent piece 6c and the second bent piece 7c are formed, the load resistance of the structure 3 can be sufficiently increased without the third surface 8.

  The bendable part 6b and the bendable part 7b are separated by a slit 13 formed between them. Similarly, the bendable part 7b and the bendable part 8b are separated by a slit 13 formed therebetween. As a modification, the bendable part 6b and the bendable part 7b may not be separated, and the bendable part 7b and the bendable part 8b may not be separated. For example, a perforation may be formed instead of the slit 13, and the perforation may be cut when the first bent piece 6c, the second bent piece 7c, and the third bent piece 8c are formed.

  As shown in FIG. 3, the first folding piece 6 c has a first side edge 6 d perpendicular to both the folding line 12 and the first fold line 10 of the first surface 6. The second bent piece 7 c has second side edges 7 d and 7 e perpendicular to both the fold line 12 and the first fold line 10 of the second surface 7. The first side edge 6 d is in contact with the second surface 7. According to such a configuration, the angle between the first surface 6 and the second surface 7 can be more reliably maintained, so that the load resistance of the structure 3 can be further improved. The same effect can be obtained even if the second side edge 7d is in contact with the first surface 6 instead of the above configuration.

  The second side edge 7 e is in contact with the third surface 8. According to such a configuration, the angle between the second surface 7 and the third surface 8 can be more reliably maintained, so that the load resistance of the structure 3 can be further improved. In addition, in the example of FIG. 3, the 1st bending piece 6c, the 2nd bending piece 7c, and the 3rd bending piece 8c are formed by bending only one bendable line 9, However, As a modification, a plurality of parallel The bendable line 9 may be folded to form a folded piece. For example, a plurality of parallel bendable lines 9 may be folded to form a square tubular bent piece.

  When the structure 3 is formed of a corrugated cardboard sheet, the longitudinal direction of the flute groove of the corrugated cardboard sheet may be parallel to the first fold line 10 and the second fold line 11. The compression resistance of the corrugated cardboard sheet in the longitudinal direction of the flute groove is higher than the compression resistance in the direction orthogonal thereto. For this reason, the load resistance in the height direction of the structure 3 can be further increased by arranging the longitudinal direction of the groove of the flute as described above.

  On the other hand, the longitudinal direction of the flute groove of the corrugated cardboard sheet forming the structure 3 may be parallel to the bendable line 9. By arranging in this way, it becomes easy to bend the bendable line 9, and the production efficiency can be improved.

  FIG. 4 is a schematic sectional plan view showing the packaging device 1 according to the first embodiment. FIG. 4 corresponds to a cross-sectional view of the packing device 1 cut along a plane perpendicular to the height direction of the structure 3. In the example shown in FIG. 4, the first surface 6 and the third surface 8 are in contact with the inner wall of the box 2. Thereby, since the position and posture of the structure 3 inside the box 2 can be held more reliably, the occurrence of physical distribution defects can be prevented more reliably, and the product 90 can be more reliably protected. Can do. If at least one of the first surface 6, the second surface 7, and the third surface 8 is in contact with the inner wall of the box 2, the same effect as described above can be obtained.
