(First embodiment)
A packing material according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 6, taking doors D1 and D2 attached to a passenger entrance of a normal passenger car as an example of a part to be packed. The same components as those in FIGS. 11 to 14 described above will be described using the same reference numerals.

FIG. 1 is a front view of the door D1 with the exterior case C as a cross-section when the door D1 is packed using the packing material 10 according to the first embodiment of the present invention and stored in the exterior case C. FIG. 2 is a cross-sectional view taken along line X1-X1 of FIG.
As shown in FIGS. 1 and 2, the doors D <b> 1 and D <b> 2 are thin plate members having a substantially rectangular shape in plan view and a slightly curved cross-sectional shape.
When these doors D1 and D2 are transported, the packing materials 1 and 10 are fitted to the respective corners of the doors D1 and D2, and further stored in a standing posture in the exterior case C.

  The outer case C is made of a synthetic resin frame whose outer shape is formed in a rectangular parallelepiped shape, a hard paper material box formed in a rectangular parallelepiped shape, and the like, and the packing materials 1 and 10 are fitted therein. It has a space that can accommodate the door D1 and the door D2 that are put on.

As shown in FIG. 3, the packaging material 10 is integrally molded by a substantially rectangular solid foam molded body (block body).
The packaging material 10 is formed with a groove-shaped notch 12 that penetrates in one direction (in the direction of the arrow L1) from the side surface 15 toward the side surface 17 on the back side, and is formed in the horizontal direction. By this notch 12, a thin connection portion 13 is formed between the side surface 16 orthogonal to the horizontal surface.

The notch 12 forms a support block 10a to be fitted to the door D1 through the connecting portion 13 and a spacer block 10b to give a thickness to the support block 10a in the packaging material 10.
On the bottom surface 18 of the support block 10a, a fitting recess 11 is formed for fitting the packing material 10 to the upper corner of the door D1 in the standing posture.

  The connecting portion 13 is formed so that the cross-sectional area is narrower than the horizontal cross section of the support block 10a and the spacer block 10b, and is large enough for the operator to break manually, and when the door D1 is transported, the support block 10a and the spacer block Even if an impact is applied to 10b, the size is set such that the door D1 can be appropriately fixed and protected without breaking. Further, the width of the notch 12 (the separation distance between the support block 10a and the spacer block 10b) is preferably as small as possible, but is set in a range that does not hinder the molding using a mold.

  With this configuration, the packing material 10 is configured to be able to absorb and protect an impact when the door D1 is conveyed before the spacer block 10b is separated from the support block 10a.

  As shown in FIG. 4, the notch 12 is formed in the height direction as shown in FIG. 4 by breaking the packing material 10 at the connecting portion 13 as shown in FIG. 6 and separating the spacer block 10b shown in FIG. 3 from the support block 10a. When the support block 10a is fitted to the large door D2, at least the fracture surface 13a shown in FIG. 6, and preferably the fracture surface 13a and the upper surface 19 of the support block 10a in which the notch 12 is formed, are the exterior case C. It forms in the position used as the support surface T which contact | abuts the top surface C1.

  The material of the packaging material 1 is preferably a foamed molded body of a thermoplastic resin that has been foam-molded in the mold. Thermoplastic resins include polystyrene resins, polyolefin resins (eg, polypropylene resins, polyethylene resins, etc.), polyester resins (eg, polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, etc.), polycarbonate resins. And polylactic acid resin. Among these, it is desirable to use a composite resin containing polystyrene and polyethylene.

Next, the usage method of the packaging material 10 mentioned above is demonstrated. Here, FIG. 4 is a front view showing a cross section of the exterior case C in a state where the door D2 is housed in the exterior case C, and FIG. 5 is a cross-sectional view taken along line X2-X2 of FIG.
First, when packing the small door D1, as shown in FIG. 1, when the packing material 1 is fitted to the corner of the door D1, the upper edge of the door D1 in the standing posture and the top of the exterior case C are placed. A large gap is formed between the surface C1 and the packing material 10 is fitted to the corner of the door D1 with the spacer block 10b. And the door D1 is stood up so that the packing materials 1 and 1 may come below, and the package A which packed the door D1 is inserted in the exterior case C. Then, the packing body A slides on the inner wall of the outer case C, and the packing materials 1, 1, 10, 10 are in the corners of the outer case C in a state where the packing materials 1, 10 are contained in the outer case C. It is positioned and can be transported safely.

  On the other hand, since the door D2 has a height higher than that of the door D1, when the packing materials 1 and 10 are directly fitted to the door D2, the package A becomes larger than the height of the exterior case C1. Therefore, when packing the door D2 larger than the door D1, the spacer block 10b is separated from the support block 10a before the packing material 10 is fitted to the door D2.

In order to separate the spacer block 10b from the support block 10a, as shown in FIG. 3, the end of the spacer 10b that is the farthest from the connecting portion 13 is gripped, and this end is used as an action point. The spacer 10b is rotated around the center (fulcrum) to change its posture.
Then, a strong stress is applied to the connection portion 13 with a light force due to the displacement of the spacer block 10b, the connection portion 13 is easily broken, and the spacer block 10b can be easily separated from the support block 10a (see FIG. 6).

Next, the packing material 10 which is only the support block 10a is fitted into the corner portion of the door D2, and is inserted into the outer case C1 as shown in FIG. Then, as shown in FIG. 6, the upper surface 19 and the fracture surface 13a of the support block 10a after the spacer block 10b is separated are substantially flush with each other. Since the support surface T is set in contact with the top surface C1 of C, the door D2 fitted with the packing materials 1 and 10 can be inserted into the exterior case C2 while sliding.
Then, the door D2 in the exterior case C is exteriorized so that when the packaging materials 1 and 10 are brought into contact with the four corners, the packaging materials 1 and 10 are brought into contact with the inner wall surface and corners of the exterior case C. It is stored in the case C and positioned.

As described above, according to the packaging material 10, the height of the packaging material 10 can be easily adjusted manually according to the dimensions of the doors D <b> 1 and D <b> 2. The effect that it can raise is acquired.
Moreover, since the packing material 10 provided with the support block 10a and the spacer block 10b is integrally formed via the connection part 13, the effect that a metal mold | die cost can be suppressed in manufacture of the packing material 10 is acquired. .
Moreover, since the packaging material of two types of height dimensions is obtained by the one packaging material 10, it can prevent that the kind of packaging material increases, and the effect that component management can be made easy is acquired. It is done.
