A second embodiment to be described next differs from the first embodiment described above in the shape of the inner bottom wall of the interior member. The second embodiment will be described below, focusing on the differences from the first embodiment, and illustrations and explanations of the same points will be omitted.

FIG. 10 is a developed view showing the interior member in the second embodiment, and FIG. 11 is a diagram showing a state in which an article is fixed to the inner bottom wall of the interior member shown in FIG. 10. In addition, in FIGS. 10 and 11, components equivalent to those of the first embodiment shown in FIGS. 1 to 9 are denoted by the same reference numerals as in FIGS. 1 to 9, and duplicate explanations are omitted. do. 10 and 11 also show the same X-axis, Y-axis, and Z-axis as in the first embodiment.

In the interior member 210 according to the second embodiment, the inner bottom wall 211 is provided with a notch 211d corresponding to the article 150. This notch 211d is a rectangular hole that follows the shape of the rectangular inner bottom wall 211. Moreover, the interior member 210 is provided with a folding ruled line 214 in a shape in which the folding ruled line 144 in the first embodiment is hollowed out by a cutout portion 211d. The forming portion of the ceiling side plate 113 is a linear ruled line 114b extending linearly in one row in the first direction, similar to the first embodiment. On the other hand, in the forming portion of the inner bottom wall 211 and the first side wall 112, two rows of arcuate ruled lines 114a that curve convexly and spaced apart from each other in the second direction D12 in the first embodiment are formed in the middle by the notch 211d. This is a hollow circular arc-shaped ruled line 214a.

Also, in this second embodiment, the tiers of the corrugated paperboard forming the interior member 210 are along the first direction D11, as shown by the tier mark M11 similar to the first embodiment. This direction is the direction in which the thinnest portion of the inner bottom wall 211 extends, and the steps are along this direction. This increases the strength of this thinnest part.

As shown in FIG. 11, the fixing sheet 120 covers the article 150 housed in the notch 211d along with the inner bottom wall 211 in the second direction D12. As a result, the article 150 is held between the front and back sides of the fixed sheet 120 in a stretched state while floating relative to the inner bottom wall 211. At this time, the inner bottom wall 211 receives a force from the fixing sheet 120 that causes the two thinnest portions described above to approach each other in the second direction D12. The size and shape of the notch portion 211d are such that the shape of the inner bottom wall 211 can be maintained against such force.

Also in the second embodiment described above, since the structure other than the notch 211d of the interior member 210 is the same as the first embodiment, it is possible to obtain a good appearance after packaging and high article protection performance. Needless to say, it is also possible to improve workability when removing articles.

In this embodiment, the interior member 210 is provided with a notch 211d, and the article 150 is fixed to the inner bottom wall 211 by the fixing sheet 120 while being accommodated in the notch 211d. As a result, the article 150 is placed on the outer bottom wall 131 of the exterior member 130 with the fixing sheet 120 in between, so that the article 150 is placed on the outer bottom wall 131 of the packaging case after packaging, that is, on the article carrier. The dimension in the direction can be reduced by the thickness of the inner bottom wall 211.

In this way, according to the present embodiment, the assembly work is easy during packaging regardless of the experience of the packer, so it is possible to improve work efficiency. After packaging, a good appearance and high article protection performance can be obtained, and when unpacking, the article 150 can be taken out quickly. Furthermore, by reducing the size of the packaging case 100, it is possible to save packaging materials.

Note that the first and second embodiments described above merely show typical forms, and the present invention is not limited to these embodiments. That is, those skilled in the art can implement various modifications based on conventionally known knowledge.

For example, in the first and second embodiments described above, the rectangular box-shaped packaging case 100 and the article packaging body 1 are illustrated. However, the shape of the packaging case or article package is not limited to a rectangular box shape, but can be specifically shaped as long as the pair of opposing first side walls and the opposing pair of second side walls are lined up so that their opposing directions intersect with each other. It is not a question of box shape. For example, it may have an octagonal prism shape, or a box shape in which side walls other than the four side walls described above are curved.

Further, in the first and second embodiments described above, the packaging case 100 and the article packaging body 1 are illustrated in which the sealing tape 160 is attached so as to cover a part of the outer bottom wall 131. However, the shape of the sealing tape is not limited to this, and for example, it may be pasted across the outer bottom wall in the first direction as well as on the ceiling side.

There is. However, the pair of ceiling door walls is not limited to this, and may have the same length as each other, for example.

Further, in the first and second embodiments described above, the cylindrical fixing sheet 120 that is formed of a heat-shrinkable shrink film and fixes the article 150 to the inner bottom wall 111, 211 is exemplified. However, the fixing sheet is not limited to this, and the specific material thereof does not matter. Further, the shape of the fixed sheet is not limited to a cylindrical shape, and the sheet may be arranged so as to cover the articles housed in the inner bottom wall of the interior member, and its shape and arrangement method are not limited. For example, one end of the fixing sheet formed in a band shape is glued to the back side of the inner bottom wall, the other end is pulled so that the article is wrapped inside the inner bottom wall, and the other end is attached to the back side of the inner bottom wall. It may also be in the form of adhesion or the like. Further, in order to assist in taking out the article, the fixed sheet may be provided with perforations or the like so that it can be easily torn.

Furthermore, in the first and second embodiments described above, the folding sheet has two rows of arcuate ruled lines 114a, 214 extending in the first direction D11 and one row of linear ruled lines 114b extending in the first direction D11. A form in which the bending lines 114, 214 are provided on the interior members 110, 210 is illustrated. However, the folding ruled line is not limited to this. In other words, as long as the folding lines are provided at least at a position closer to the center of the inner bottom wall, questions are asked about whether or not they are formed in areas other than the inner bottom wall, and the specific number and shape of the folding lines. isn't it. For example, the bending ruled lines may be provided only on the inner bottom wall and not on the first side wall or the ceiling side plate, and the number of bending lines may be one or three or more. Further, the folding ruled line may have a shape other than a circular arc or a straight line, for example, a trapezoid shape. Further, the direction in which the folding ruled line extends is not limited to the first direction, which is the direction in which the first side wall of the interior member faces, but may extend in the second direction that intersects with the first direction. Furthermore, when providing two or more folding ruled lines, some of the folding ruled lines may extend in the first direction, and other folding ruled lines may extend in the second direction. However, as mentioned above, the workability when removing the article 150 can be improved by providing at least two rows of arcuate ruled lines 114a, 214a extending in the same direction as the folding ruled lines 114, 214. That's right. Further, as described above, by providing at least two rows of arc-shaped ruled lines 114a, 214a as the folding ruled lines 114, 214, inadvertent deformation before taking out the article can be suppressed.

Furthermore, in the second embodiment described above, the notch 211d is provided in the inner bottom wall 211, and the fixing sheet 120 covers the article 150, which is accommodated in the notch 211d, together with the inner bottom wall 211. ing. However, as in the first embodiment, the inner bottom wall may not be provided with any cutouts or the like. However, by providing a notch 211d in the inner bottom wall 211 and storing and fixing the article 150 therein, the dimensions of the packaging case 100 and the article package 1 can be reduced by the thickness of the inner bottom wall 211. The things that can be done are as described above. Incidentally, what is provided on the inner bottom wall is not limited to a notch, but may be a slit, as long as it is provided in accordance with the article and the article can be stored inside.

Further, in the second embodiment described above, the notch 211d provided in the inner bottom wall 211 is rectangular, but its specific shape is not limited. For example, a circular or elliptical notch may be provided to improve durability against force from the fixed sheet in an expanded state.

Furthermore, in the first embodiment described above, recesses are provided in the ceiling door wall 133 and the outer bottom wall 131, and the sealing tape 160 is also attached to the exposed wall surface from each recess. However, it is also possible not to provide any recesses in the ceiling door wall or the outer bottom wall. However, as described above, by providing such a recessed portion, high fixing strength can be obtained by the sealing tape 160.

Further, in the first embodiment described above, the recesses are provided in both the ceiling door wall 133 and the outer bottom wall 131, but the recesses may be provided in only one of the walls.

Furthermore, in the first and second embodiments described above, the first side wall 112 of the interior member 110, 210 is provided with the first protruding piece 112c and the second protruding piece 112d for suppressing the collapse. .
