Description

[Detailed Description of the Invention] This invention relates to a cushioning packaging material, and is intended to obtain a cushioning packaging material that can be separated into individual packages for each item after collectively packaging the items.

Conventionally, individually packaged cushioning packaging materials made of synthetic resin foams such as expanded polystyrene have had shapes suitable for individual packaging from the beginning, and collective packaging materials have been designed to accommodate multiple items to be packaged from beginning to end. The shape was suitable for collective packaging, which is convenient for handling such as transportation.

However, after manufacturing the product to be packaged, it is easier to handle it in collective packaging until it reaches the distributor, but once it is delivered to the distributor, it is more convenient to handle each packaged item individually. Therefore, there is a need for a cushioning packaging material suitable for this purpose.

Therefore, this invention was devised to meet the above-mentioned needs, and its structure consists of a plurality of single bodies made of synthetic resin foam, each of which is provided with a storage recess. Two pieces of cushioning packaging materials of the same shape are fitted together so that the storage recesses match each other, and each unit has a substantially trapezoidal cross section, and there is a gap between the units that is close to the continuous boundary. A V-shaped groove with a narrower groove width is formed, and a thinner boundary part is formed in the V-shaped groove, so that the single unit can be made into a pair of two pieces with matching storage recesses, and the boundary can be separated. It is characterized by being configured so that it can be separated from the section.

Next, embodiments of this invention will be illustrated below with reference to the drawings.

Reference numeral 1 designates the entire cushioning packaging material, which is integrally formed of a synthetic resin foam such as expanded polystyrene.

10 is a single unit each provided with a storage recess 11 suitable for the items to be stored. The single body 10 is formed to have a substantially trapezoidal cross section, and the entire cushioning packaging material 1 is made up of a plurality of these single bodies 10 that are integrally connected, and the same-shaped cushioning packaging material 1
, 1 are fitted in sets of two so that the respective storage recesses 11° and 11 match.

Reference numeral 12 denotes a V-shaped groove provided at the boundary 13 of the continuous single bodies 10, and the groove width is narrower as the groove 12 approaches the continuous boundary 13 of the single bodies 10.10. Applicable V
By forming the boundary part 13 in the groove part 12 in a thin shape, the single unit can be separated into two pieces with the storage recesses 11 and 11 aligned.

Furthermore, 14.15 is a concave and convex portion that can be fitted to each other, and the single unit 10.10 is a combination of the cushioning packaging materials 1 and 1 (the fifth
They are alternately formed so that they can be fitted together when closing (Fig. 7), etc., and are suitable for preventing the cushioning packaging materials 1, 1 from shifting.

In addition, as the synthetic resin foam forming the above-mentioned cushioning packaging material 1, the foamed polystyrene mentioned above is preferable, but in addition, foams manufactured from polyethylene, polypropylene, polyvinyl chloride, copolymers mainly composed of these, etc. It is also possible to carry out the process using a foam body, or even a foam body in which polystyrene and polyethylene are chemically bonded.

This invention has the above-mentioned configuration, and to describe an example of its use, a cushioning packaging material 1 having a plurality of single units 10 is used as a set of two cushioning packaging materials 1.1 of the same shape as a half-housing of the same shape. After putting the packaged object B into the storage recess 11.11 formed between the two and combining them, seal the joined end surfaces of each single unit 10.10 with a label 20 or the like, and then seal it every half a day during handling such as transportation. This is to prevent it from decomposing into pieces.

When the packaged items B are sold one by one at a distributor etc. after transportation, the thin boundary portion 13.1 between the individual items 10 and 10 is
At point 3, using the V-shaped groove 12.12, the folded units can be separated from the boundary portion 13.13 into pairs with the four storage portions matching each other.

Therefore, it is possible to easily switch the collectively packaged items to the individual package state, and the separation into the individual package state is also possible.As mentioned in Section 2, each unit 10 having a storage recess 11 has a substantially trapezoidal cross section, and is V-shaped. Since the groove width is narrower as the groove 12 is closer to the continuous boundary portion, the groove width on the outside is wider than the single unit 10.
．． When folding and separating the weights of No. 10, it is easy to put your fingers in and it is easy to handle, and it can be done by simple bending at this V-shaped groove part 12 and the boundary part 13, so separation can be achieved extremely easily. This has excellent practical effects such as ease of handling and handling.
