<Background and Prior Art> Conventionally, steering wheels and other ring-shaped articles of automobiles, etc. have a large internal space, resulting in waste of packaging space, and are difficult to package. In the case of a product having a centrally protruding hub portion, etc., it is difficult to stack and package a large number of products, making it difficult to handle. For example, conventionally, as shown in FIG. 5, two upper and lower fixing members h and h' are inserted into a rectangular box, and the outer periphery of a ring-shaped article such as a handle is inserted into the insertion groove formed in the fixing members. They were inserted 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 aims to solve the above-mentioned problems with conventional packaging materials for ring-shaped articles, and aims to provide a packaging material that is efficient in storage, easy to pack, and suitable for transportation and storage. purpose.

<Structure> The structure of this invention to achieve the above-mentioned purpose is to arrange a plurality of elongated packaging materials made entirely of synthetic resin foam in parallel at intervals, and to create ring-shaped parts such as handles, etc. The arc-shaped rim portion of the article is accommodated and supported within the left and right packaging materials, and the packaging material at both ends is formed with a plurality of arc-shaped recesses capable of accommodating only one of the left and right arc-shaped rim portions of the annular article; The arcuate recesses are formed alternately with deep recesses and shallow recesses, and in the first intermediate packaging material facing the end packaging material among the central packaging materials, the arcuate recesses of the end packaging material Deep arc-shaped recesses and shallow arc-shaped recesses are formed in sequence to face each other, and arc-shaped recesses that intersect with each of the above-mentioned arc-shaped recesses and draw arcuate curves in opposite directions are formed. The arcuate recesses are formed to have a shallow depth that is opposite to that of the arcuate recesses, and the second intermediate packaging material disposed opposite to the first intermediate packaging material has a depth that is opposite to that of the arcuate recesses of the first intermediate packaging material. It is characterized in that arc-shaped recesses are formed facing each other at line-symmetrical positions, and furthermore, on the upper and lower surfaces of each packaging material, fitting uneven parts for mutual stacking are formed.

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

The packaging materials include an end packaging material 1, a first intermediate packaging material 2,
There are three types, ie, a second intermediate packaging material 3, and all of them are made of foamed synthetic resin such as expanded polystyrene and are formed into an elongated, substantially rectangular shape.

The above-mentioned packaging materials are sequentially arranged in parallel at regular intervals, and a ring-shaped article H such as a handle is stored between the left and right adjacent packaging materials. 1, the first intermediate packaging material 2, the second intermediate packaging material 3, the second intermediate packaging material 3, the first intermediate packaging material 2, and the end packaging material 1 are arranged in this order.

First, as the end wrapping material 1, a ring-shaped article H is placed on the upper surface.
A plurality of arcuate recesses 10a and 10b (three in the figure) are arranged in parallel in the longitudinal direction and are capable of accommodating only one of the left and right arcuate rim parts r, of which the first arcuate recess 10a is The next arcuate recess 10b is formed shallowly, and the next arcuate recess 10a is formed shallowly again to form a shallow recess 10a.
and deep recesses 10b are arranged alternately. Further, on the upper and lower surfaces of the end packaging material 1, mutual stacking fitting protrusions 11 and recesses 12 are formed, which are used when the packaging materials 1 are stacked vertically.

Next, as the first intermediate packaging material 2, arcuate recesses 20a and 20b are formed on the upper surface of the end packaging material 1 in positions opposite to the respective arcuate recesses 10a and 10b of the end packaging material 1.
are formed, and these arcuate recesses 20a, 20b
From the top, a shallow recess 20a, a deep recess 20b,
and a shallow recess 20a. Therefore, the left and right arcuate rims r of the annular article H are connected to opposing recesses of the end wrapping material 1 and the first intermediate wrapping material 2, such as the shallow arcuate recesses 10a and 20a or the deep arcuate recess 1.
If the ring-shaped articles H are stored and supported in 0b and 20b, the ring-shaped articles H can be stored in a horizontal state.In this case, for the ring-shaped articles H that are stored adjacent to each other in the longitudinal direction, the front and rear arcuate rim parts are vertically aligned. They are designed to be stored crisscrossing each other.

In addition, if there is a hub portion h etc. that protrudes in the vertical direction at the center of the ring-shaped article H, shallow recesses 10a and 20a
The ring-shaped article H to be stored in between has its protruding hub part h
If the ring-shaped article H to be stored between the deep recesses 10b and 20b is stored with the hub portion h facing upward, the protruding hub portion h and the like will not protrude above and below the packaging materials 1 and 2, and can be suitably protected.

Further, on the upper surface of the first intermediate packaging material 2, arcuate recesses 21a and 21b are formed which intersect with the arcuate recesses 20a and 20b and draw arcuate curves in the opposite direction.The depths of these arcuate recesses 21a and 21b are arranged in the order of deep recess 21b, shallow recess 21a, and deep recess 21b from the top, opposite to the intersecting arcuate recesses 20a or 20b. Note that 22 and 23 are fitting uneven portions for stacking the first intermediate packaging materials 2 together.

Next, as the second intermediate packaging material 3, each arcuate recess 20a, 20 of the first intermediate packaging material 2 is formed on the upper surface.
Arc-shaped recesses 30a, 30b, 31a, 31b are formed in line-symmetrical positions with the recesses 30a, 30b, 31a, 31b, respectively. Therefore, between the first intermediate packaging material 2 and the second intermediate packaging material 3, the shallow arcuate recess 21a and the shallow arcuate recess 30a that face each other form a pair to accommodate one ring-shaped article H, and similarly The deep arcuate recess 21b and the deep arcuate recess 30b form a pair. The arcuate rim r of the annular article H to be stored in the arcuate recesses 20a and 20b of the first intermediate packaging material 2 and the arcuate rim r of the annular article H to be stored in the arcuate recesses 21a and 21b intersect vertically. Since they are stored, they are stored on top of each other without touching or interfering with each other.

Further, in the illustrated embodiment, the same second intermediate packaging material 3 is placed next to the second intermediate packaging material 3 with its front and back (vertical direction in FIG. 1) reversed, so that these two Since the shallow arc-shaped recesses 31a of the second intermediate packaging material 3 face each other, and the deep arc-shaped recesses 31b face each other, the ring-shaped articles H can be stored therein. Reference numerals 32 and 33 are concave and convex portions provided on the upper and lower surfaces of the second intermediate packaging material 3 for stacking each other.

In the illustrated embodiment, the first intermediate wrapping material 2 and the end wrapping material 1 are arranged next to the second intermediate wrapping material 3, which is arranged with the front and back directions reversed. By arranging a total of six wrapping materials in parallel, it is possible to simultaneously store 15 ring-shaped articles H in five rows of three in one row.

In addition, for practical purposes, four packaging materials are used: the end packaging material 1, the first intermediate packaging material 2, the second intermediate packaging material 3, and the end packaging material 1 in which the front and back are reversed. When combined, 3 ring-shaped articles H can be made in 1 row for 3 rows 9
The first intermediate packaging material 2 and the second intermediate packaging material 3 can be stored and used at the same time.
By adding these one after another, the number of ring-shaped articles H that can be stored can be freely increased from three in one row to seven, nine, etc.

Further, in the case of the embodiment, a portion of both ends of the hub portion h of the ring-shaped article H has entered into the first and second intermediate packaging materials 2 and 3, and the shape of the hub portion h is not symmetrical. In the intermediate packaging material 2 and the second intermediate packaging material 3, each arcuate recess 20a, 20b, 21
a, 21b and arcuate recesses 30a, 30b, 31a,
The shape of the end portion is slightly different from that of 31b.

However, if the arcuate recesses have the same shape in use, it is possible to form the first intermediate packaging material 2 and the second intermediate packaging material 3 in exactly the same shape and arrange them alternately in the front and rear directions during use. Therefore, it is also possible to use them separately as the first and second intermediate packaging materials 2 and 3.

Furthermore, as a modified aspect, each packaging material 1, 2, 3
4 or more arcuate recesses 10a, 10b in the longitudinal direction of
It is also possible to form... However, the arcuate recess 10a
If the number of items is even, etc., each packaging material 1,
If the front and back directions of packaging materials 2 and 3 are reversed, the deep recess and the shallow recess may not be able to be placed opposite each other, making it unusable. This can be solved by manufacturing products with different shallow and deep order in the longitudinal direction.

<Effects> According to the packaging material of this invention configured as described above, a plurality of ring-shaped articles H stored between the packaging materials
The arc-shaped rim parts r that are adjacent to each other in the front and rear and left and right directions are stored in a state where they intersect each other vertically and are overlapped with each other at intervals, so that a large number of ring-shaped articles H can be buffered without interfering with or coming into contact with each other. This means that it can be efficiently and compactly stored with good performance and minimal volume.

Further, on the upper and lower surfaces of each of the packaging materials 1, 2, and 3, recessed and recessed portions 11, 12, 22, 23, 32, and 33 are formed to fit each other so that the packaging materials can be stacked vertically. Therefore, when stacking the packaging materials containing the ring-shaped articles H, they can be stacked stably and accurately, making it easy to perform packing operations for storage in containers, etc., and making it convenient to use.

Of the respective packaging materials 1, 2, and 3, the first and second intermediate packaging materials 2, 3 disposed between the end packaging materials 1 at both ends are sequentially increased or decreased to increase or decrease the ring-shaped article H to be stored. Since the number of ring-shaped articles H can be changed freely, it is highly flexible and can easily accommodate changes in the number of ring-shaped articles H to be packaged or changes in the mode of transport using containers or the like.

Furthermore, even if there is a complex-shaped part such as a hub part h protruding from the center of the ring-shaped article H, since only the arc-shaped rim part r of a relatively simple shape is accommodated in the packaging materials 1, 2, and 3, the hub part h There is no need to consider much about the shapes of the packaging materials 1, 2, 3, etc., and manufacturing such as molding of the packaging materials 1, 2, and 3 becomes easy, and changes in the shape of the hub portion h and the like can be easily accommodated.

Furthermore, the packaging material and non-wrapping material are combined to give an appearance as if they were integrated, and multiple packaging materials are arranged in parallel at intervals to wrap only the left and right arcuate rims r of a ring-shaped article H such as a handle. Since the annular article H is stored and supported within the packaging material, there is no need to store the entire ring-shaped article H within the packaging material, resulting in savings in packaging material. In addition, since it can be manufactured and handled separately into individual packaging materials 1, 2, and 3, it is easy to manufacture.
Transporting and storing 2 and 3 itself is also easier.

The packaging material of this invention can be applied to steering handles of automobiles, etc., operating handles of various machines, wheel rims of automobiles, etc., and various other ring-shaped articles.
