Embodiment.
FIG. 1 is a development view of an embodiment of a packaging material according to the present invention. This packaging material can be assembled from a single sheet-like member (for example, a cardboard sheet). In addition, the dashed-two dotted line in FIG. 1 has shown performing valley trough in the case of an assembly. In addition, a one-dot chain line in the drawing indicates that the mountain is folded during assembly. By assembling the packaging material, two solar cell modules can be packaged. Side wall forming part 3 and side wall forming part 4 protrude from each side of bottom face forming part 1 on which a solar cell module as an object to be packaged is placed. A top surface forming portion 6 projects beyond the side wall forming portion 3. A top surface forming portion 7 protrudes beyond the side wall forming portion 4. That is, the packaging material protrudes foldably from the substantially rectangular bottom surface forming portion 1, the side wall forming portions 3 and 4 protruding from each side of the bottom surface forming portion 1, and the side wall forming portions 3 and 4. It is a “tattoo type” having top surface end forming portions 6 and 7.

  A partition plate 2 protrudes from the bottom surface forming portion 1 on both sides of the side wall forming portion 3. A flap 5 protrudes from the side wall forming portion 4 in a direction orthogonal to the direction in which the top surface forming portion 7 protrudes. Further, a flap 8 protrudes from the top surface forming portion 7 substantially in parallel with the flap 5.

  The protruding amount of the side wall forming portion 4 is slightly smaller than the protruding amount of the side wall forming portion 3.

  A hole 1 a and a groove forming portion 14 are provided at the boundary between the side wall forming portion 4 and the bottom surface forming portion 1. The concave groove forming portion 14 is formed by slightly biting into the bottom surface forming portion 1 side so as to rise from the surface of the bottom surface forming portion 1.

  FIG. 2 is a partially enlarged view of the side wall forming portion 3 and the top surface forming portion 6. As in FIG. 1, the alternate long and two short dashes line indicates that the valley is folded during assembly. A notch 11a is formed in a side (first side) serving as a boundary between the side wall forming unit 3 and the bottom surface forming unit 1 and a side (second side) serving as a boundary between the side wall forming unit 3 and the top surface forming unit 6. , 13a are formed. The notch 11a has a substantially U-shape so that the bottom surface forming portion 1 protrudes from the side wall forming portion 3 (it protrudes toward the side wall forming portion 3). In addition, the cut 13a has a substantially U shape so that the top surface forming portion 6 protrudes from the side wall forming portion 3 (projects toward the side wall forming portion 3). The cuts 11a and the cuts 13a are arranged so as not to be symmetric with respect to the side wall forming part 3. That is, the notch 11a is provided on the side that forms the boundary between the side wall forming part 3 and the bottom surface forming part 1, and the notch 13a is provided on the side that serves as the boundary between the side wall forming part 3 and the top surface forming part 6. It is arranged so that it does not overlap with the part that is not. Here, the cuts 11a and 13a are shown as an example of a substantially U-shape that protrudes toward the side wall forming part 3, but the cuts 11a and 13a are curved shapes that are convex toward the side wall forming part 3 side. Also good.

  A procedure for assembling the packaging material will be described. First, the first solar cell module is placed in the center of the bottom surface forming portion 1. Thereafter, the partition plate 2 is bent. At this time, it is bent along the valley fold lines 2 a and 2 b, and the protrusion 2 c is inserted into the hole 1 a formed at the boundary between the bottom surface forming portion 1 and the side wall forming portion 4. When the partition plate 2 is bent, the second solar cell module is placed on top of the first solar cell module. Next, the side wall forming part 3, the side wall forming part 4 and the flap 5 are bent to form side walls. At this time, a cut-and-raised structure is formed by the notch 11a at the ridge portion 9 formed by the boundary between the side wall forming portion 3 and the bottom surface forming portion 1. A gap (slit) 11b is formed. Further, the groove forming part 14 is bent so as to be substantially parallel to the side wall forming part 4. Further, the top surface forming portion 6 and the top surface forming portion 7 are bent to form the top surface, and the solar cell module is wrapped. At this time, a cut-and-raised structure is formed at the ridge 10 formed by the boundary between the side wall forming portion 3 and the top surface forming portion 6 by the notch 13a. A gap (slit) 13b is formed. Then, the flap 8 is bent and sealed. FIG. 3 is a perspective view of the packaging material after assembly.

  In the packaging material after assembly, the portion where the concave groove forming portion 14 is provided is in a state of being recessed inward from the side wall forming portion 4. Therefore, the band can be prevented from shifting by packing the packaging material so that the binding band fits into the recess.

  In the above embodiment, the gaps 11b and 13b are formed in the ridges 9 and 10 at the time of assembly by providing the notches 11a and 13a. However, instead of the notches, the ridges It is also possible to form a gap. However, if a notch is provided to form a gap at the ridge, generation of waste material can be suppressed.

  FIG. 4 is a side view of the packaging material after assembly and shows a short side. FIG. 5 is a perspective view of the short side of the packaging material after assembly. A gap 11b formed by the cut-and-raised structure is arranged at the ridge 9 and a gap 13b is arranged at the ridge 10, respectively.

  FIG. 6 is a view showing a deformed state of the short surface of the packaging material when the load is absorbed by the gaps 11b and 13b to reduce swelling and buckling. Fig.6 (a) shows a part of short surface of the packaging material seen from the front, FIG.6 (b) shows the AA cross section in FIG. By forming the cuts 11a and 13a, the length (pitch) of the portion (root portion 12) remaining as the ridge portions 9 and 10 is shortened, the strength is lowered, and the root portion 12 is easily crushed locally. Therefore, as shown in FIG. 6, the portion where the gaps 11 b and 13 b are formed and the root portion 12 are locally deformed, so that the swelling and buckling are alleviated. In addition, this makes it difficult for swelling and buckling to occur near the center of the side wall forming portion 3. Accordingly, swelling and buckling that cause deformation in an indefinite shape are alleviated, and aesthetics and stability are maintained. That is, swelling and buckling can be reduced without using a chamfered structure.

  FIG. 7 is a side view of the packaging material in which the gaps 11b and 13b are arranged alternately (in a staggered manner) (arranged asymmetrically with respect to the protruding direction (vertical direction) of the side wall forming portion 3). As shown in FIG. 7, the end of the gap 11b and the end of the gap 13b may overlap in the vertical direction. Therefore, by alternately disposing the gaps 11b and the gaps 13b, a portion that does not become the gap 11b at the ridge portion 9 and a portion that does not become the gap 13b at the ridge portion 10 do not overlap in the vertical direction. become. Thereby, the force which acts on the side wall which the side wall formation part 3 makes can be absorbed in at least one of the clearance gaps 11b and 13b.

  FIG. 8 is a side view of the packaging material arranged so that the gaps 11b and 13b are aligned in the vertical direction (symmetrically arranged with respect to the protruding direction (vertical direction) of the side wall forming portion 3). When the gap 11b and the gap 13b are aligned in the vertical direction, a portion where the portion remaining in the ridge portion 9 without the gap 11b and the portion remaining in the ridge portion 10 without the gap 13b overlap with each other occurs. If a portion where the gap 11b is not formed and a portion where the gap 13b is not formed overlap in the vertical direction, the load is not absorbed, so that there is a concern that the central portion in the vertical direction is deformed so as to be convex, resulting in body swelling or buckling. is there. Therefore, the portion where the gap 11b of the ridge portion 9 is not formed and the portion where the gap 13b of the ridge portion 10 is not formed do not overlap in the vertical direction (the direction perpendicular to the direction in which the side wall forming portion 3 protrudes from the bottom surface forming portion 1). It is necessary to.

  Thus, the packaging material which concerns on this Embodiment can make the side wall which the side wall formation part 3 formed contact or adjoin the solar cell module which is a to-be-packaged object. Therefore, the packaging material can be reduced in size and weight.

  In addition, although the packaging material which has a clearance gap only in the ridge part which a short side wall formation part makes here was demonstrated as an example, even if a packaging material has a clearance gap only in the ridge part which a long side wall formation part makes It is good, and you may have a clearance gap in each of the ridge part which the short side and long side side wall formation part makes. Moreover, you may have a clearance gap only in the ridge part which any one of the side wall formation part makes. That is, according to the shape of the article to be packaged, a gap can be provided at the ridge formed by any side wall forming part.

  As described above, the packaging material according to the present invention is useful in that it can relieve body swelling and buckling even if the packaged object is in a shape in contact with the side wall or the top surface. Suitable for packaging plate-like objects.
