Description

[Detailed Description of the Invention] <Technical Field> This invention relates to a cushioning packaging material, and more particularly to a cushioning packaging material capable of accommodating a plurality of handles for automobiles and other ring-shaped articles.

<Background and Prior Art> Conventionally, the packaging of handles and other ring-shaped articles for automobiles, etc. has a large internal space, which tends to waste a lot of packaging space, and the articles are difficult to package. In the case of items such as the steering wheel of an automobile, which have a centrally protruding hub portion, it is difficult to stack and package a large number of items, making them difficult to handle. For example, conventionally, as shown in FIG. 12, two upper and lower fixing members h and h' are inserted into a rectangular parallelepiped box, and a ring-shaped article H such as a handle is inserted into the insertion groove formed in the fixing members. The outer periphery was fitted and fixed one after another, and multiple pieces were packaged for transportation and storage. However, the storage efficiency per unit volume was poor and there was room for improvement in terms of packaging work.

<Purpose> This invention solves the above-mentioned problems with conventional packaging materials for ring-shaped articles such as handles, and provides a cushioning packaging material that has good storage efficiency, is easy to pack, and is suitable for transportation and storage. The purpose is to

<Structure> The structure of this invention to achieve the above object is a packaging material formed entirely of synthetic resin foam into a substantially rectangular parallelepiped shape, with at least one side of the packaging material having: A plurality of storage recesses are provided in which a plurality of handles and other ring-shaped articles can be sequentially stored in an inclined state, and the ring-shaped parts of adjacent ring-shaped articles are formed so as to intersect and overlap each other, Furthermore, the entrance of the recess is characterized by forming a protrusion that projects into the recess and is inclined so as to become narrower toward the inside.

<Example> Next, an example of this invention will be illustrated below with reference to the drawings.

Reference numeral 10 indicates the entire packaging material, which is formed of a synthetic resin foam into a substantially rectangular parallelepiped shape. 11,
11... are a plurality of storage recesses formed on one side of the packaging material 10 capable of storing a plurality of handles, two-wheeled vehicle rims, or other ring-shaped articles A; Each of the ring-shaped articles A can be stored and is formed so that adjacent ring-shaped articles A that have been stored intersect with each other at a part of the ring-shaped part and overlap each other (see especially FIG. 4).

12, 12... are protrusions 13, 13... formed at the entrances of the storage recesses 11, 11... so as to protrude into the recesses 11, 11... and become narrower toward the inside (Fig. 5). ), ring-shaped articles A such as handles
The protrusion 1 is inserted from the wide side and becomes narrower towards the inside.
Once pushed into the recesses 11, 11 from points 2 and 12 using the elasticity of the foam, the ring-shaped article A
This can prevent objects from floating up or flying out during transport, etc.

Reference numerals 15 and 16 are fitting uneven portions formed on the outer periphery of the packaging material 10 and connect the packaging materials 10 and 10 to each other.

Note that in practice, there are recesses 11, 1 for storing the ring-shaped article A such as a handle on only one side of the packaging material 10.
In addition to forming 1..., if a plurality of recesses 14 are formed on the other side to accommodate one side b1 of another article B such as an instrument panel, the other side b2 of the other article B can be accommodated. This makes it convenient to combine packaging materials 20 made of synthetic resin foam having recesses 21, and for one packaging material 10, the packaging materials 20 can be combined in multiple proportions (in the case of the figure, 3
It will be easier to package if you combine the
0 and 11).

Reference numerals 22 to 25 are fitting uneven portions formed on the outer periphery of the packaging material 20, which interconnect the packaging materials 20, 20 vertically and horizontally.

The foam forming the above-mentioned packaging materials 10 and 20 may be foamed polystyrene, or a styrene-maleic anhydride copolymer composed of 2 to 25% by weight of maleic anhydride and 98 to 75% by weight of styrene. Coalescence or as above, add 2 to 25 maleic anhydride
When using a foam made of a blend of a styrene-maleic anhydride copolymer containing % by weight and another thermoplastic resin (such as polybutadiene), the heat resistance can be improved more than that of foamed polystyrene.

<Effects> According to the packaging material of this invention configured as described above, the ring-shaped articles A such as handles are not individually wrapped, but a plurality of ring-shaped articles A can be stored in an inclined state in sequence, and adjacent ring-shaped articles A can be stored in a tilted state. Since the packaging material 10 has a plurality of recesses 11, 11, . Can be stored efficiently.

In addition, since the entire packaging material is made of synthetic resin foam, if the ring-shaped article A is stored a little too tightly, it will tend to stick to the recesses 11, 11, etc., which is a characteristic of foam. Coupled with the cushioning properties of the recesses 11, the ring-shaped article A, etc. can be protected in a good storage condition within the recesses 11, 11, . . .

In particular, a protrusion 1 that protrudes into the recess 11 at the entrance of the recess 11, 11, and slopes so as to become narrower toward the inside.
2, 12..., so once the recesses 11,
It is possible to prevent the annular article A stored in the recesses 11 from deviating from the recesses 11, 11, . . . due to a shock or the like during transportation.

As described above, the cushioning packaging material of this invention can easily store handles and other ring-shaped items extremely reliably, efficiently, and has excellent practical effects such as facilitating the transportation and storage of these items. It is possible.
