Next, the operation of the above configuration will be described. The packing material is a piece of cardboard 1 so that it does not become bulky during storage and transportation.
It is expanded to the state of 00. This cardboard 100,
In order to fold up the keyboard 300 by folding it up in the form of a packing material, first, the side surface packing forming surfaces 22 and 22 are cut off from the corrugated board 100 along the perforations W, and the peripheral wall surface 1 is formed by the surface adhesive margin 6 portions. Assemble into a rectangular tube. However, the work of assembling the rectangular tube may be performed at the stage of manufacturing the packaging material. Next, the lower packing forming surfaces 15 and 16
Bend each other at a right angle,
When the contact pieces 9 and 10 are bent at a right angle along the fold line F while facing each other at a right angle, the bottom surface of the box is formed, and the insertion piece raised from the bottom surface in a butt shape is formed. The bottom is reinforced by the pieces 9 and 10.

Next, when the lower U-shaped bent piece 20 is bent downward, the fitting slits g and the fitting notches h and i at the positions where they interfere with the abutting pieces 9 and 10. Mesh with each other so that bending can be performed without any hindrance, and the shape of the bent lower packing 201 is fixed (FIG. 6).

On the other hand, the side surface packing forming surface 2 which has been cut off
2 is folded in the form of the side packing 203 shown in FIG.
Defer as shown in 5.

After that, when the keyboard 300 is laid between the lower packings 201, 201 and installed in a buffered state, both end faces and front and rear side faces of the keyboard 300 are respectively attached to the side face packing 203. The contact surface 22b is abutted with a slight gap left. At this time,
The locking projections a projecting from both ends of the abutting pieces 9 and 10 perform a positioning function for mounting.

Subsequently, the upper U-shaped bent piece 21 (upper packing forming surfaces 17 and 18) is bent in a U shape, and the step surface forming fold f is bent downward at a right angle, and then horizontally. The contact surface 21d is brought into contact with the upper surfaces of both end portions of the keyboard 300. At this time, the bent pieces 21c provided on each strip 21b are bent at right angles so as to be in contact with the front and rear side surfaces of the keyboard 300. Further, the tip end portion of the U-shaped bent piece 21 is inserted into the gap between the side end surface of the keyboard 300 and the contact surface 22b. In this state,
In the portion where the bent U-shaped bent piece 21 and the abutting pieces 9 and 10 buffer each other, the buffer slits g and the buffer cutouts h and i mesh with each other, and the bending can be performed without trouble. The shape of the folded upper packing 202 is fixed (FIG. 6).

Then, finally, by bending each of the half-side lid surfaces 11 and 12 and the insertion pieces 13 and 14 downward at right angles, the box is closed and the closed state is fixed.
Thus, the packing operation of the keyboard 300 is simple, quick, and reliable, unlike the rather complicated description above. In this packed state, the keyboard 30
0 is buffered and supported by the upper and lower both side packings 201 and 202 having the cushioning performance which is comparable to the conventional foamed polystyrene packing of which the both side ends are one set at the upper and lower sides. Bending piece 21c and contact surface 22
b is in a state of being abutted in a buffer manner, and the keyboard 30
The buffer holding state of 0 is perfect. Then, if an impact force exceeding the shock absorbing performance is exerted on the keyboard 300 during transportation, the load bearing surfaces 20e, 20f, 21 will be removed.
The presence of the cushioning notch Y formed in e causes the load bearing surfaces to buckle and deform, thereby effectively dampening an excessive impact force and reliably protecting the keyboard from the impact force.

In the above structure, the load bearing surface 20
The shape of the buffer cut X provided in e, 20f, and 21e is
Not limited to the U-shape, the point is that when an excessive impact force exceeding the set value is applied to the load bearing surface, the load bearing surface on which the buffer notch Y is formed by the buffer cut X is formed as described above. For example, a U-shape or a semi-circular shape may be used as long as the shape, arrangement, and number are such that they buckle. or,
The side surface side packing forming surface 22 is an edge portion other than the insertion pieces 13 and 14, for example, an edge portion of the abutting pieces 9 and 10 or a side edge of the side wall 2 according to the shape and size of the packaging box. It may be connected to. And, of course, the packed article is not limited to the keyboard.

[0023]

As is clear from the above description, the packaging material for the keyboard and the like according to the present invention exhibits various excellent practical effects as listed below. a) It is composed of the only corrugated cardboard that has creases, cuts, etc. at the required multiple points, and the packaging box is formed by simply folding along the creases and it is comparable to the conventional Styrofoam packing. The cardboard packing with shock absorbing performance can be bent easily and quickly. b) Therefore, it can be provided at a lower cost than the conventional one, and the packing work can be performed efficiently. c) The need to use styrofoam packing, which is a waste of finite and precious oil resources and is awkward to dispose of, saves global resources and reduces the problem of waste disposal, which is becoming more serious. Can contribute. d) Since the packaging material can be stored and transported in the form of a single flat cardboard box, it is possible to reduce storage and transportation costs and purchase management costs.
