  However, according to the packaging material of Patent Document 1 described above, since the grooves 2a, 3a, 4a are formed with play between the packaged parts F, the projections are formed on the plate surface of the packaged parts F. In the case where a portion is provided, even if a certain clearance is provided between the front end of the protruding portion and the plate surface of the packaged component F facing the packaged component F, the packaged component F remains in the grooves 2a, 3a, 4a. There has been a problem that when the swinging, the projection and the plate surface of the part F to be packaged facing each other come into contact with each other and may be damaged.

  Further, in order to prevent the tip of the protruding portion from coming into contact with the plate surface of the part to be packed F facing the clearance, the clearance must be set large, and a large number of parts F to be packed must be packed in the packing material 1. There was a problem that could not.

  In view of the above problems, the present invention provides a plate-shaped packaged component having a protrusion on the plate surface without damaging other packaged components and prevents the packaged component from swinging. It is an object to provide a packing material that can be placed.

The protrusion includes a protection member accommodated therein, and the protection member is inserted into the protection member while elastically deforming the protrusion when the part to be packed is packed. The protrusion is gripped and fixed, and is densely interposed between the plate surface of one packaged component and the plate surface of another packaged component facing the packaged component.
In the present invention, the protruding portion is accommodated inside the protective member, and the protective member is closely interposed between the plate surface of one packaged component and another packaged component facing the same. Therefore, it is possible to prevent the tip of the protruding portion from coming into contact with the plate surface of another packaged component, and the protective member keeps the space between the plate surfaces of the packaged component at a constant interval.
Moreover, since the protection member is inserted into the protrusion and attached, the attachment is simple. Further, when the protrusion is inserted into the protective member, the protective member is elastically deformed around the portion where the protrusion is inserted. At the site where this elastic deformation has occurred, an elastic restoring force is generated, and it is fixed so as to be urged against and grasp the protruding portion. Therefore, it is difficult to drop off during transportation.

The invention of claim 2 is characterized in that, in the packaging material according to claim 1, the protective member is formed of an olefin-based foamed resin material, and the foaming ratio is 30 times or more and 60 times or less. To do.
In the present invention, the protective member is preferably a foamed polypropylene resin or a foamed polyethylene resin, particularly as the olefin foamed resin material. And since the expansion ratio is 30 times or more and 60 times or less, it is easy to insert the protrusions, and can respond to the swing of the packaged parts with an appropriate elastic deformation force, and the protective member is used when unpacking. Even when separated from the protrusion, fragments of the protective member are unlikely to occur.

According to the packaging material which concerns on this invention, there exist the following effects by the above-mentioned solution means.
That is, according to the packing material of the present invention, the protrusion is accommodated inside the protective member, and the protective member is tightly placed between the plate surface of one packaged component and the other packaged component facing this. Therefore, it is possible to prevent the tip of the protrusion from coming into contact with the plate surface of another packaged component, and the protective member keeps the interval between the plate surfaces of the packaged component at a constant interval. Accordingly, it is possible to prevent damage to the packaged parts adjacent to the tip of the projecting part and the projecting part, and to prevent the plurality of packaged parts from swinging inside the packaging material and to transport the packaged parts suitably. There is an effect that can be done.

  Further, since the protective member is inserted into the protruding portion and attached, it is easy to attach, and it is difficult to drop off during transportation, so that the packaging and unpacking operations are simple.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a part to be packaged that is an application target of the packaging material shown as one embodiment of the present invention.

As shown in FIGS. 1 and 2, the part to be packed that is packed by the packing material A of the present embodiment is a large thin plate member that has low rigidity such as glass. In the present embodiment, the present embodiment will be described by exemplifying an automobile windshield 10 as a part to be packed.
The windshield 10 is formed in a substantially rectangular shape when viewed from the front, and is provided with positioning projections (protrusions) 11 and 11 for positioning the windshield 10 on a plate surface 10a near the upper corner.

  As shown in FIGS. 1 and 3, the positioning projection 11 has a circular and flat bulged portion 11a mounted on the plate surface 10a, and a sharp point substantially perpendicular to the plate surface 10a from the center of the bulged portion 11a. And a pin 11b that protrudes from the top.

  As shown in FIG. 2, the packaging material A for packaging the windshield 10 is interposed between the packaging material main body 12 that supports a plurality of positions at the end of the windshield 10 at intervals and the windshields 10, 10. And a protective member 13 to be mounted.

  The packing material body 12 includes a rectangular parallelepiped casing including a bottom plate 14, side plates 15 and 15, and an upper lid 16, and support members 17, 17 and 18 attached to inner wall surfaces of the bottom plate 14 and the upper lid 16, respectively. Yes.

A pair of lower end support members 17, 17 made of foamed resin are arranged on the bottom plate 14 so as to face each other so as to extend in the short direction.
In the upper corners 17T of the lower end support members 17 and 17, concave grooves 17a and 17a that are notched toward the diagonal 17S and open upward and inward are formed at predetermined intervals. The corner of the lower end of the windshield 10 can be held.

  Further, on the lower surface of the upper lid 16, an upper end support member 18 that has concave grooves 18 a and 18 a penetrating in the left-right direction, that is, the direction between the lower end support members 17 and 17 and opening downward is attached. It is formed so that the upper end of 10 can be supported.

  As shown in FIGS. 2 and 3, the groove widths of the concave grooves 17 a, 18 a,... Are formed so as to gradually become narrower toward the inner side of the groove. It is set so as to be approximately the same as the thickness dimension of the end portion.

  The concave grooves 17a and 18a formed in the lower end support members 17 and 17 and the upper end support member 18 are formed such that the groove width gradually decreases toward the bottom portion 19 so that the end of the windshield 10 can be appropriately held. Although it is formed, if the groove width is too narrow, the end portion of the windshield 10 bites into the concave grooves 17a, 17a, 18a, and it becomes difficult to perform the unpacking operation. Therefore, the concave grooves 17a, 17a, and 18a are formed to allow slight play between the inner surfaces of the concave grooves 17a, 17a, and 18a and the windshield 10 when the windshield 10 is packed.

  The pitch of the grooves 17a and 18a is such that when the windshield 10 is disposed, the front end of the positioning projection 11 provided on the plate surface 10a of one windshield 10 and the windshield 10 adjacent to the windshield 10 are disposed. The gap M is set so as to be formed between the surface 10b.

As shown in FIG. 4, the protection member 13 is a member made of foamed resin that is formed in a substantially cubic shape and is elastically deformable. The protection member 13 is formed as a so-called non-hole member in which a hole for accommodating the positioning protrusion 11 is not formed in advance.
The thickness L of the protection member 13 is slightly larger than the length of the pin 11b of the positioning protrusion 11 plus the size of the gap M shown in FIG. It is desirable to be provided in the range of 8 mm.

  The material of the protective member 13 is formed of an olefin-based foamed resin material such as a foamed polypropylene-based resin or a foamed polyethylene-based resin, and is formed so that the expansion ratio is 30 to 60 times.

  Under the above configuration, when the protection member 13 is relatively pierced to a position where it can no longer enter the positioning protrusion 11, the entire pin 11b is positioned inside the protection member 13 and the windshield 10 swings. Even if the plate surface 13b of the protection member 13 is pressed with the maximum pressing force that presses the plate surface 13b of the protection member 13 when the pin 11b is pushed, the tip of the pin 11b protrudes from the plate surface of the protection member 13 and the plate surface of the windshield 10 10b is not touched.

Next, a method for packing the windshield 10 with the packing material A will be described.
First, the protective member 13 is attached to the windshield 10 to be packed. Specifically, as shown in FIG. 4, the protection member 13 is inserted so as to be inserted in the thickness L direction with the plate surface 13 b of the protection member 13 facing the pin 11 b of the positioning projection 11 of the windshield 10. The positioning protrusion 11 is relatively inserted. Then, the protective member 13 is pressed against the positioning protrusion 11 until the positioning protrusion 11 cannot enter the protective member 13 any more. At this time, since the positioning protrusion 11 is inserted while breaking and pushing the wall portion of the protective member 13 that can be elastically deformed and elastically restored, the protective member 13 is a wall portion around the portion where the positioning protrusion 11 is inserted. Elastic deformation occurs at. Then, an elastic restoring force is generated in the wall portion of the protective member 13 where the elastic deformation has occurred, and the wall portion of the protective member 13 is urged against the inserted positioning projection 11 to grip and fix the positioning projection 11. .

Next, as shown in FIG. 2, the windshields 10 and 10 provided with the protection member 13 are fitted into the mutually facing concave grooves 17 a and 17 a of the lower end support members 17 and 17 of the packaging material body 12.
Then, the protective member 13 is inserted to a position where it cannot enter the positioning projection 11 of one windshield 10 any more, and the plate surface 10a is in contact with the plate surface 10b of the other windshield 10. The windshields 10 and 10 are closely interposed between the windshields 10 and 10 so that the windshields 10 and 10 support each other in the direction between the plate surfaces 10a and 10b and become independent.

  When all the windshields 10, 10,. Put on. And the band (not shown) which consists of polypropylene etc. is wound around the packing body which packed the windshield 10 in the packing material A, this packing body is fixed firmly, and the packing operation | work of the windshield 10 is completed.

  As described above, according to the packaging material A of the present embodiment, the positioning protrusion 11 is accommodated in the protective member 13, and the protective member 13 is placed on the plate surface 10 a of the windshield 10 and the other windshield facing it. Since the windshield 10 swings and presses the plate surface 13b of the protective member 13 with the maximum pressing force, it is closely interposed between the plate surface 10b and the plate surface 10b. Even if pressed, the tip of the pin 11 b protrudes from the plate surface of the protection member 13 and does not contact the plate surface 10 b of the windshield 10. Therefore, the effect that the front-end | tip of the pin 11b of the positioning protrusion 11 and the plate surface 10b of the other windshield 10 can be protected suitably is acquired.

  In addition, since the protective member 13 is closely interposed between the windshields 10 and 10, it is possible to minimize the swing of the plurality of arranged windshields 10, 10. The effect of being able to be obtained.

  Further, since the protective member 13 supports the plate surfaces 10a and 10b of the windshields 10 and 10 at regular intervals, the support member of the packaging material body 12 that supports the windshield 10 can be minimized, and the packaging The effect that simplification of the material main body 12 can be achieved is obtained.

  Furthermore, since the protection member 13 is inserted into the positioning projection 11 and attached, it is easy to attach and it is difficult to drop off during transportation. Therefore, the packaging and unpacking operations of the windshield 10 are easy. An effect is obtained.

  Further, since the protective member 13 is formed of a foamed resin material that can be elastically deformed, the front windshields 10, 10,... Even if it swings inside, the effect of flexibly adapting to this swing and maintaining the gap between the plate surfaces 10a, 10b can be obtained.

Furthermore, the protective member 13 is formed of an olefinic foamed resin material such as a foamed polypropylene resin or a foamed polyethylene resin, and has an expansion ratio of 30 to 60 times. It is possible to obtain the effect that the windshield 10 can be swung easily with an appropriate elastic deformation force.
In the above-described embodiment, the protective member 13 is a member in which a hole for inserting the positioning protrusion 11 is not formed in advance, but is not limited to this, and to accommodate the positioning protrusion 11. These holes may be formed in advance, and the diameter of the holes may be smaller or thinner than the outer diameter or thickness of the positioning protrusion 11. Even with such a packaging material A, the same operations and effects as in the above embodiment can be obtained.
Moreover, in the said embodiment, although foamable resin is used as a material of the protection member 13, it is not limited to this, The positioning protrusion 11 can be inserted, it has a buffering property, and is to be packaged As long as the surface of the component can be protected, it may be a molded body formed using a resin material that does not have foamability, a glass fiber other than the resin material, or other fiber materials.
