The packing object illustrated here is a rectangular flat plate with a relatively large thickness by providing upper and lower horizontal frames 2A and left and right vertical frames 2B around the four circumferences of a rectangular face material 1 such as glass. This is a shoji D constructed as shown in FIG. That is, in the first embodiment, the protruding corner portion 3 of the shoji D is formed by the two surfaces 2a, 2a of the adjacent frames 2A, 2B along the perspective direction intersecting with each other. Here, the prospective direction is a direction along the depth of the fittings, as shown by arrow A in the figure. In other words, in FIG. 1, the direction perpendicular to the paper surface is the prospective direction. A surface along the prospective direction may be referred to as a prospective surface. Further, in this embodiment, the term "finding direction" is also used. In the case of something extending along the horizontal direction, such as the side stile 2A, the finding direction is a direction along the top and bottom orthogonal to the viewing direction. In the case of something that extends along the vertical direction, such as the vertical stile 2B, the direction along the horizontal line orthogonal to the viewing direction is called the finding direction. A surface along the finding direction may be referred to as a finding surface.

The packing buffer 10 for packing the above-mentioned shoji D is vacuum molded from a resin such as polypropylene, and is constructed so that each part described below has a substantially constant thickness. As shown in FIGS. 4 to 6, the packing buffer 10 includes two auxiliary cover parts 11 and two main cover parts 12. The auxiliary cover part 11 is arranged so as to cover the surface of the shoji D (the facing surface 2b of the frames 2A and 2B). In the first embodiment, the auxiliary cover part 11 has a flat plate shape in the shape of an approximately right-angled isosceles triangle, and has two equilateral parts 11a and one hypotenuse part 11b extending in substantially perpendicular directions to each other. There is. The main cover part 12 is arranged so as to cover the prospective surfaces 2a of the two frames 2A and 2B that constitute the protruding corner part 3 of the shoji D, and has a substantially rectangular shape. Each main cover part 12 is provided so as to connect the equilateral parts 11a of the two auxiliary cover parts 11 to each other, and has a shape that accommodates the protruding corner part 3 of the shoji D between the two auxiliary cover parts 11. A triangular prism-shaped accommodating portion 13 is configured. The accommodating portion 13 has a dimension along the perspective direction that is slightly larger than a dimension of the shoji D along the perspective direction, and is open only in a portion corresponding to the oblique side portion 11b of the auxiliary cover portion 11.

As shown in FIGS. 4 to 6, each of the main cover parts 12 is provided with a support part 14 at one extending end that is spaced apart from each other, and at the other extending end that is close to each other. A buffer portion 15 is provided at the end, and a recessed portion 17 is formed between the support portion 14 and the buffer portion 15. The support portions 14 are hollow platform-shaped portions that protrude from one extending end of the concave portion 17 toward the outer circumferential side of the shoji D, respectively. More specifically, the support body part 14 includes a leg wall part 14a that extends from one extending end of the concave part 17 so as to be bent toward the outer circumferential side, and an extending edge of the leg wall part 14a. It has an abutting wall portion 14b extending from the recessed portion 17 so as to be substantially parallel to the recessed portion 17. The dimension of the abutment wall portion 14b along the direction of the projection is configured to be smaller than the total width of the main cover portion 12. Side wall portions 14c are provided on both sides of both side edges of the contact wall portion 14b, respectively.

The buffer portions 15 extend from the other extending end of the concave portion 17 so as to bulge toward the outer circumferential side of the shoji D, and then extend in a direction toward each other. More specifically, the buffer portion 15 includes a protruding wall portion 15a extending from the concave portion 17 in a bent manner toward the outer circumference, and an extending edge portion of the protruding wall portion 15a extending toward each other in a direction close to each other. It has a base wall portion 15b. In the buffer body part 15, the extending edges of the base wall parts 15b are joined to each other, and the parts on both sides are each covered by the above-mentioned auxiliary cover part 11. A sealed buffer space 16 is formed by the portion 11 and the projecting wall portion 15a. This buffer space 16 communicates with the housing portion 13 and bulges outward from the housing portion 13 .

The concave portion 17 is formed into a flat shape by ensuring a gap between the buffer portion 15 and the support portion 14. The outer surface 17a of the concave portion 17 is located on the inner circumferential side so as to be recessed relative to the outer surface 15d of the buffer body portion 15 and the outer surface 14d of the support body portion 14 that protrude toward the outer circumferential side. Similarly, the inner surface 17b of the concave portion 17 facing the shoji D is located on the inner peripheral side so as to be recessed relative to the inner surface 15e of the buffer portion 15 and the inner surface 14e of the support portion 14. There is.

Further, in the packaging buffer 10, a plurality of protrusions 18 are provided on the base wall portion 15b of the buffer portion 15. In the first embodiment, by forming a plurality of prospect grooves 19a along the perspective direction of the shoji D in the portion extending from the base wall portion 15b of the buffer body portion 15 to the auxiliary cover portion 11, the grooves 19a are formed along the direction perpendicular to the perspective direction. In other words, a plurality of protrusions 18 are arranged in parallel along the lengths of the frames 2A and 2B. Furthermore, by forming a plurality of longitudinal grooves 19b in the base wall part 15b of the buffer body part 15 along the length of the frames 2A, 2B, a plurality of protrusions 18 are arranged in parallel along the expected direction of the shoji D. It has been set up. As is clear from FIG. 6, the height of the protrusion from the concave portion 17 of the plurality of protrusions 18 arranged in parallel along the length of the frames 2A, 2B gradually increases as the distance from the protruding corner portion 3 increases. They are arranged like this. The plurality of protrusions 18 arranged in parallel along the prospective direction of the shoji D are configured to have the same shape. These plurality of protrusions 18 each independently protrude toward the outer circumferential side. Therefore, even if adjacent protrusions 18 undergo a shape change such as collapse, they are less likely to be affected by the change. In addition, in the buffer body part 15 in which a plurality of protrusions 18 are provided on the base wall part 15b, the peripheral wall part 18a constituting each protrusion part 18 and the bottom wall part 19c of the grooves 19a and 19b protrude into the buffer space 16. It is arranged as follows.

As shown in FIG. 1, the packing buffer 10 configured as described above is arranged at the four corner parts 3 of the shoji D with each of the projecting corners 3 being arranged inside the storage part 13. Ru. Further, a packing tape T made of a resin film is wrapped around the packing buffer 10 so as to cover each surface. Thereby, each packing buffer 10 is maintained in a state where the shoji D is mounted. Here, according to the above-mentioned packaging buffer 10, the recessed part 17 is provided between the buffer part 15 and the support part 14, the outer surface 17a of which is located on the inner circumferential side. Therefore, by wrapping the packing tape T around this concave portion 17, even if the shoji D is dragged while being transported, foreign objects will be prevented from coming into sliding contact with the packing tape T. There is no risk that the packaging tape T will wear out. Thereby, there is no possibility that the packaging buffer 10 will accidentally fall off from the shoji D.

In the packaging shock absorber 10 disposed on the shoji D as described above, the shock absorber portion 15 is disposed corresponding to the portion that becomes the protruding corner portion 3. The inner surface 15e of the buffer portion 15 is separated from the shoji D by the inner surface 17b of the recessed portion 17 coming into contact with the prospective surfaces 2a of the frames 2A, 2B. Furthermore, the buffer body portion 15 is provided with a plurality of protrusions 18 so as to protrude toward the outer circumference. As described above, these protrusions 18 are not easily affected by changes in the shape of adjacent protrusions 18, and the respective peripheral wall portions 18a and the bottom wall portions 19c of the grooves 19a, 19b are It is arranged so as to protrude into the buffer space 16. Therefore, when an external force is applied toward the protruding corner portion 3, such as when a foreign object comes into contact with it during transportation, the peripheral wall portion 18a of the protruding portion 18 and the bottom wall portion 19c of the grooves 19a and 19b are sequentially moved against the shoji D. While in contact with each other, the protrusion 18 collapses in stages and absorbs the external force. As a result, the entire shock absorbing body part 15 is not crushed, there is no possibility of external force being transmitted to the protruding corner part 3 of the shoji D, and the situation of causing damage to the protruding corner part 3 is more reliably prevented. becomes possible.

In the first embodiment described above, the shoji D is the object of packing, but the packing buffer can be applied to other objects as long as they have a polygonal shape with the protruding corners 3. It is. In addition, since the packing buffer 10 is exemplified as having two auxiliary cover parts 11, it is less likely to be misaligned with respect to the packing object, but the present invention does not necessarily include the auxiliary cover parts 11. There's no need to be. Furthermore, although one shock absorber section 15 is provided across the two main cover sections 12, an independent shock absorber section 15 may be provided for each main cover section 12. In this case, it is sufficient that the ridgeline portion of the protruding corner portion 3 does not come into contact with foreign objects, and the buffer portion does not necessarily need to cover the ridgeline portion of the protruding corner portion 3 .

(Embodiment 2)
FIG. 7 shows a packing state of an object to be packed to which a packing cushion according to the second embodiment of the present invention is applied. The packing object illustrated here is, for example, a cubic box E in which parts for fittings are housed, and has eight projecting corners 3'. That is, in the second embodiment, the protruding corner portion 3' is formed by three surfaces P of the box E that extend perpendicularly to each other and intersect with each other.

In the packaging shock absorber 20 disposed in the box E as described above, the shock absorber portion 24 is disposed corresponding to the portion that will become the protruding corner portion 3'. The inner surface of the buffer portion 24 is separated from the surface P of the box E by the inner surface 25b of the concave portion 25 coming into contact with the surface P of the box E. Furthermore, the buffer body portion 24 is provided with a plurality of protrusions 27 so as to protrude toward the outer circumference. As described above, these protrusions 27 are not easily affected by changes in the shape of adjacent protrusions 27, and the respective peripheral wall portions 27a and the bottom wall portions 28a of the grooves 28 serve as buffer spaces. It is arranged so as to protrude from 26. Therefore, when an external force is applied toward the protruding corner 3', such as when a foreign object comes into contact with it during transportation, the peripheral wall portion 27a of the protruding portion 27 and the bottom wall portion 28a of the groove 28 are sequentially moved against the box E. While in contact, the protruding portion 27 collapses in stages and absorbs the external force. This prevents the entire shock absorber section 24 from being crushed, eliminates the risk of external force being transmitted to the protruding corner 3' of the box E, and more reliably prevents damage to the protruding corner 3'. It becomes possible to prevent this.

In the second embodiment described above, the cubic box E is the object of packing, but other boxes such as a rectangular parallelepiped box may be used as long as the three surfaces P have protruding corners 3'. It is possible to apply the packing buffer 20 to objects to be packed. In this case, the three surfaces P do not necessarily have to extend perpendicularly to each other. Furthermore, although one buffer section 24 is provided across the three main cover sections 21, an independent buffer section 24 may be provided for each main cover section 21. In this case, it is sufficient that the apex of the protruding corner portion 3' does not come into contact with foreign objects, and the buffer portion 24 does not necessarily need to cover the apex of the protruding corner portion 3'.
