DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner shock absorber for protecting a ventilation fan and the like during transportation and storage.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 7, for example, a cushioning device of this type comprises an upper cushioning material 2 in which a packaged object 1 such as a ventilation fan is located at an upper portion, and a lower cushioning material 3 located in a lower portion is made of cardboard. It is known that the lower cushioning material 3 is provided and held in an outer box 4, and in particular, the lower cushioning material 3 is formed of styrene (see, for example, Japanese Utility Model Publication No. 57-30308).

[0003]

THE INVENTION Problems to be Solved] The styrene described above
The shock absorber used has many problems related to disposal, and
Many attempts have been made to construct with easy-to-handle cardboard materials.
I have. To obtain cushioning performance comparable to styrene with cardboard material
Has a polymerized structure, but with one piece of cardboard
Form two or three planes at right angles to a triple or quadruple structure
Difficult. Alternately opposite for folding by folding screen
The reverse ruled line that bends in the direction is required, and the production requires two processes.
In addition, it is necessary to accurately form post-process ruled lines on pre-process ruled lines.
Is difficult. Ruled lines can be the same if they are rolled up
However, the number of ruled lines increases because the thickness increases with each overlap.
Must also be changed sequentially.

[0004] The present invention solves the above-mentioned conventional problems.
It was made for the purpose and the purpose
Is an easy-to-manufacture shock absorber with good disposal properties and shock absorbing function.
It is to get.

[0005]
