Description

[Detailed explanation of the invention] <Technical field> This invention relates to cushioning packaging materials.
The present invention relates to a cushioning packaging material for packaging an article, such as a counter, having a protrusion of a predetermined width on the upper side of the side surface with good cushioning properties and efficient storage.

<Prior Art> Conventionally, when packaging a counter as an article having a protrusion of a predetermined width at the upper part of the side surface with good cushioning properties, the counter is individually wrapped in paper, a foam sheet, etc. and then packed in a box. Alternatively, it is common practice to enclose the entire counter with a synthetic resin sheet molded product having a storage recess that fits the shape of the counter, and to package the counter individually in boxes.

<Problems to be solved by the invention> All of the above-mentioned packaging methods have problems in that the packaging is troublesome and the packaging cost is high. In particular, when using synthetic resin sheet molded products, it is necessary to form storage recesses of various shapes depending on the counter, and for high-mix, small-lot products, this becomes even more disadvantageous in terms of cost, and storage Since deep drawing is required to form the recesses, there is a problem in that manufacturing is difficult. In addition, since they are individually packaged, there is a problem in that they are bulky and inconvenient when handling a large number of counters at once.

<Purpose> This idea was created in view of the above-mentioned problems, and focused on the fact that most counters generally have a fixed bottom shape and a different top shape. Including, similar items can be stored efficiently.
It is an object of the present invention to provide a buffer packaging material that can be packaged at low cost and that can be easily manufactured.

<Structure> The cushioning packaging material of this invention to achieve the above object is a cushioning packaging material for storing an article having a protrusion of a predetermined width at the upper part of the side surface, and is made entirely of a synthetic resin sheet. The storage main body for storing the lower part of the article and the lid part for storing the upper part of the article are connected in a bendable manner via a hinge part, and the storage main body includes: A plurality of rows of recesses for storing the lower parts of articles individually are arranged at predetermined intervals, and adjacent recesses are arranged symmetrically so that the storage direction of the protrusion of the article can be changed for each row. In addition, the space between the recessed portions is configured as a placement portion for each of the protrusions of adjacent articles, and the placement portion allows the protrusions of adjacent articles to be placed in a mutually interlocking manner. The lid is set to a width that allows the lid to be placed side by side, and is further characterized in that the lid is formed with ribs that can come into contact with each other between the recesses of the housing body.

<Example> Hereinafter, an example will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing the cushioning packaging material of this invention in an open state, and in the case of the figure, the cushioning packaging material for a counter is illustrated.

As shown in the figure, the cushioning packaging material of this invention is
A synthetic resin sheet, preferably a synthetic resin foam sheet such as a polystyrene foam sheet, is integrally molded by a sheet forming method such as vacuum forming,
Lid bodies 2, 2 having a width approximately half of the width of the storage body 1 are formed on both sides of the central storage body 1. The lid parts 2, 2 are connected to both sides of the storage part main body 1 via a hinge 3 made of a U groove, a V groove, etc., and by folding back from the hinge 3, the lid parts 2, 2 are connected to both sides of the storage part main body 1. Can cover the entire top.

The storage main body 1 has recesses 11, 1 in which the lower part 41 of the counter 4 as a stored article can be individually stored.
2 are arranged in a plurality of rows at predetermined intervals, and the adjacent recesses 11 and 12 are arranged symmetrically so that the storage direction of the protrusion 43 formed on the side surface of the counter top 42 can be changed. It is located in
However, in the case of the figure, since the lower part 41 of the counter 4 has a symmetrical rectangular shape, the adjacent recesses 11 and 12 are arranged line-symmetrically. The space between the recess 11 and the recess 12 is configured as a placing part 13 for the counter protrusion 43, and the placing part 13 is located between the protruding parts 43 of the adjacent counters 4, 4. 43 are formed in a width that allows them to be stored in a state where they are intertwined with each other.

On the other hand, the side on the hinge 3 side of the lid body parts 2, 2 and the two sides on both sides thereof have a predetermined height so that the upper part 42 of the stored counter 4 can be completely covered when the lid is closed. A circumferential side 21 of the storage part body 1 is formed, and a rib 22 that can come into contact between the recessed parts 11 and 12 of the storage part main body 1 is formed in a predetermined plane part. In the case of the figure, the ribs 22 are formed in a direction perpendicular to the placing part 13, and are configured to be in contact with the recesses 11, 11 and the rows 14 of the recesses 12, 12 of the storage part main body 1. has been done. Furthermore, a stepped portion 24 is formed on either one of the lid portions 2, 2, which can be overlapped with the abutting side portion 23 of the other lid portion 2 in the closed state. , so that the lid can be reliably closed at the two abutting portions.

With the above configuration, each recess 1 of the storage main body 1
By sequentially inserting the lower part 41 of the counter 4 into 1 and 12, the lower part 41 of the counter 4
can be stored in the storage main body 1, and by folding back and closing the lid parts 2, 2, the upper part 42 of the counter 4 can be covered with the lid parts 2, 2. Furthermore, the protrusions 43 of the adjacent counters 4 accommodated in the respective recesses 11 and 12 can be accommodated in a staggered state in the mounting section 13. Further, since the area around the counter top 42 is free, counters 4 having different shapes of the top 42 can also be packaged. In particular, when the lid is closed, the ribs 22 of the lid body parts 2, 2 come into contact with the upper part of the storage part main body 1.
It can also exhibit good pressure resistance against loads applied from above. Moreover, since the ribs 22 are formed in a direction perpendicular to the placing part 13 of the storage part main body 1, the horizontal direction (the first
Movement in the direction of arrow A in the figure can be reliably prevented. In order to prevent the lid parts 2, 2 from opening after closing, for example, the abutting parts of the lid parts 2, 2 may be fixed with adhesive tape t (see Fig. 3). ).

The cushioning packaging material of this invention can also be used as a packaging material for articles other than the above-mentioned counter 4, which have protrusions on the sides of the upper part. Recessed portion 11,1
2 may be formed into a contour shape that fits the lower part of each stored article. If the lower part has an asymmetrical shape, the recessed part 11 and the recessed part 12 are
It will be implemented by placing it on a point target.

In addition, the ribs 22 of the lid parts 2, 2 are formed in a discontinuous manner only in the portions corresponding to the recesses 11, 12 of the storage part main body 1, and the lid parts have the same width as the storage part main body 1. Various design changes can be made without changing the gist of this invention, such as connecting this to one side of the storage section main body 1 to make it a single-opening type.

<Effects> According to the shock-absorbing packaging material of this invention constructed as described above, the lower part of the stored article is sequentially inserted into each recess of the storage main body, and the lid is closed by folding back the lid. Since a large number of items can be packaged in a lined manner, packaging work can be done very efficiently, and the protrusions on the top of the items can be stored in a staggered manner, saving space. Good storage efficiency can be ensured, and as a result, transportation costs can be reduced. Moreover, when storing and transporting the cushioning packaging material itself, it can be handled in a flattened state, so that storage space can be reduced and transportation costs can be reduced.

In addition, since the storage of articles is shared between the storage unit main body and the lid body, the molding depth of the recess in the storage unit main body can be made shallow, and it is possible to achieve ease of manufacturing the packaging material itself. In addition, since the upper part of the article is left free when packaging, even if the upper part has a different shape, it can be packaged without any problems, and by sharing the cushioning packaging material, packaging costs can be reduced for a wide variety of small lots of articles. can be reduced.

Furthermore, when the lid is closed, the ribs on the lid body are
Since it is in contact with the upper surface of the mounting section, it can exhibit excellent pressure resistance even against external pressure from above.

Therefore, it is convenient when handling a large number of items having protrusions of a predetermined width at the upper part of the side surfaces, such as counters, at once, and it is possible to package items with good cushioning properties, efficient storage, and low cost. Moreover, the packaging material itself is easy to manufacture, and has various excellent practical effects.
