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 packaging space, and is difficult to package. In the case of items that have a centrally protruding hub, such as a car steering wheel,
Stacking and packaging a large number of items was difficult and difficult to handle. For example, as conventionally shown in FIG. 13, two upper and lower fixing members h and h' are inserted into a rectangular box, and the outer circumference of a ring-shaped article H such as a handle is inserted into a fitting groove formed in the fixing members. The conventional practice was to fit and secure the pieces one after another, package them, and use them 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> The purpose of this invention is to solve the above-mentioned problems of conventional packaging materials for ring-shaped articles, and to provide a packaging material that has good storage efficiency, is easy to pack, and is suitable for transportation and storage. There is.

<Structure> The structure of this invention to achieve the above object is that the packaging material is entirely made of synthetic resin foam, and the packaging material has fitting concave and convex portions that connect each other, a handle, etc. Two rows of main recesses and sub-recesses are formed in which the ring-shaped articles can be stored, and the two rows of main recesses allow only one arc of the ring-shaped article to be stored to protrude from the packaging material, and each of the two rows of main recesses can accommodate the ring-shaped articles. The above-mentioned two rows of sub-recesses are arranged side by side on the left and right so that the articles can be stored in an inclined state, and when the packaging materials are connected and used, the above-mentioned ring-shaped articles stored in the adjacent packaging materials are arranged side by side. The protruding arc,
The products are formed so that they can be stored on the extension line of the main recesses of adjacent packaging materials, so that parts of ring-shaped products stored at an angle in adjacent packaging materials can be stored in a manner that intersects with each other. It is characterized by

<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 made of synthetic resin foam and has two rows of main recesses 11 that can accommodate ring-shaped articles A such as handles in an inclined state.
r, 11l are formed. The packaging material 10 is formed to be narrower in width than the ring-shaped article A to be stored, and has fitting uneven portions 12, 12' formed on the side edges in the left and right direction.
This allows the packaging materials 10 to be successively connected to each other in the left and right direction.

The main recess 11r, 1 for storing the ring-shaped article
1l, a ring-shaped article A is placed in a narrow packaging material 10.
When the annular article A is stored, the right side main recess 11r, in which the right side arc protrudes from the packaging material 10, and the left side main recess 11l, in which the left side arc protrudes from the packaging material 10, are arranged to the left and right of each other. They are placed side by side in a staggered manner. Regarding the right side main recess 11r, a part of the ring-shaped article A also protrudes from the fitting recess 12' provided at the side end of the packaging material 10, but it is designed so that it can be stored inside the outer end of the packaging material 10. It's summery.

Reference numeral 13 denotes a projection for fixing the annular article A, which is formed protrudingly on the outer periphery of the main recesses 11r and 11l at appropriate locations, and is deformed by utilizing the elasticity of the synthetic resin foam. If the ring-shaped article A is fitted into the main recesses 11r and 11l and stored, the protrusion 13 will return to its original state after storage, thereby preventing the ring-shaped article A from slipping out and preventing the shock during transport. Even against vibration, the main recess 11 of the ring-shaped article A
r, preventing escape from 11l (see Figure 3).

14r and 14l are two rows of sub-recesses for storing adjacent ring-shaped articles, and when a plurality of packaging materials 10 are connected from side to side and used, the ring-shaped articles A stored in the adjacent packaging materials 10 in an inclined state This is to accommodate the protruding arched parts of the left and right main recesses 1.
A sub-recess 14r and a sub-recess 14l are provided on the extension lines of 1r and 11l, respectively. Therefore, the left and right adjacent ring-shaped articles A, A are stored in a state tilted in the same direction, and the ring-shaped articles A, A are stored in each main and sub-recess so that the left and right arcs partially intersect with each other. 1
1r, 11l, 14r, and 14l are formed.

Note that the main recess 11 for storing ring-shaped articles in the packaging material 10
A recess 15 is formed on the rear surface of the r, 11l side to accommodate another component B such as an instrument panel, so that the space of the packaging material 10 can be used effectively (see FIG. 4).

Particularly when storing a long object such as an instrument panel B, one side end b of the instrument panel B is stored in the packaging material 10, and a recess formed in another packaging material 20 made of the same material as the packaging material 10 is used. If the other end b' of the panel B is housed in the container 25 (see FIGS. 10 and 11), the packaging form is easy to handle and has excellent cushioning properties, and it is also simple and inexpensive to manufacture. It becomes suitable. Note that this other packaging material 20 will be easier to handle if it is provided with fitting uneven portions 22, 22' for interconnection in the same manner as the packaging material 10 described above (see FIGS. 5 to 7). .

Furthermore, if the main recesses 11r, 11l, etc. for storing ring-shaped articles are formed symmetrically on both sides of the packaging material 10 so as not to interfere with each other, the number of ring-shaped articles A stored on the front and back sides of the packaging material 10 can be doubled. This is a preferred implementation that improves space utilization efficiency (not shown).

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. If a foam made of a styrene-maleic anhydride copolymer containing 2 to 25% by weight of maleic anhydride and another thermoplastic resin (such as polybutadiene) is used,
It has better heat resistance than expanded polystyrene or the like, and is suitable for storage where it is exposed to direct sunlight or when transiting by ship through the tropics.

Next, a method of using the packaging material 10 will be described. The packaging material 10 can be used alone, but usually a plurality of packaging materials are used in a connected state. At this time, the ring-shaped article A can be stored in either the left main recess 11l or the right main recess 11r.

However, for the left and right outermost ones of the connected packaging materials 10, the leftmost packaging material 10 stores the ring-shaped article A in the right main recess 11r, and the rightmost packaging material 10 stores the ring-shaped article A in the left main recess. Try to store it in 11l. In this way, the connected packaging materials 10,
The stored ring-shaped article can be stored without protruding from either the left or right end of 10 (see FIGS. 8 and 9).

As described above, a plurality of packaging materials 10 connected on the left and right sides can be further combined in multiple rows, packed in an exterior body C such as a container or a wooden frame, and transported and stored (see FIG. 12). In this way, when the packaging material 10 is used side by side not only left and right but also in the vertical direction, the packaging material 10 has not only the fitting uneven parts 12 and 12' in the left and right direction but also the upper and lower ends for mutual connection. It is preferable to form a fitting concavo-convex portion to make handling easier (not shown).

In addition, the ring-shaped articles A to be stored in the packaging material 10 include steering wheels of automobiles, rims of two-wheeled vehicles, precision mechanical parts such as large piston rings, ring-shaped high-precision gears, etc. during transportation and storage. Various ring-shaped articles A that require sufficient protection
The main recesses 11r, 11l, 14r, 14 formed in the packaging material 10 according to the shape of each article.
The shape of l can be changed freely.

<Effects> According to the packaging material of this invention constructed as described above, a ring-shaped article can be stored in a tilted state in a plurality of connected packaging materials, and one of the left and right arcs of the ring-shaped article can be separated from each packaging material. Since the packaging material is protruded and stored, the individual packaging materials can be small, making manufacturing, transportation and storage of the packaging materials easier.

In addition, the arc of the ring-shaped article protruding from each wrapping material allows parts of the ring-shaped articles stored in adjacent packaging materials to be intersected and stored one after another, so that a large number of ring-shaped articles can be stored in a minimum amount without sacrificing cushioning properties. It can be stored compactly with a volume of .

Therefore, the combined packaging material as a whole is much smaller than individual packaging, and packaging material costs, packaging costs, and transportation costs are much lower than in the past.

In addition, by using the fitting uneven parts, any number of packaging materials can be connected and used, making it easy to change the number of packaging items for ring-shaped articles. It is easy and convenient to handle during storage.

Furthermore, each packaging material has two rows of main recesses and sub-recesses on the left and right, so when in use, at both ends of the connected multiple packaging materials, the left end packaging material is The right-hand main recess can be used for the right-hand side main recess, and the left-hand main recess can be used for the right-most packaging material. Therefore, the stored ring-shaped article can be completely stored in the packaging material at either the left or right end, and is sufficiently protected by the good cushioning properties provided by the synthetic resin foam.

In particular, when the packaging material is further stored in an exterior body such as a container, the ring-shaped article does not protrude outside the packaging material, so the packaging material can be packed into a rectangular container etc. without any gaps, making the packing process easier. Efficient transportation can be achieved.
