[0002]

2. Description of the Related Art An example of such a corner pad is shown in FIG. This corner pad 31
Are fitted into the corners of the product 32 and are housed in the packaging box 33 together with the product 32.

In this way, the outer surface of the corner pad 31 comes into contact with the inner surface of the packaging box 33 to suppress the rattling of the product 32 in the packaging box 33 and to absorb the impact applied from the outside. Perform a function.

[0004]

However, since the conventional corner pad 31 is made of Styrofoam as a material, it causes pollution during disposal after use. Accordingly, its use is being shunned.

Further, the conventional corner pad 31 described above is
Since it is formed into a substantially cubic shape, it has the drawback of being bulky when stored when not in use.

Therefore, this invention is preferable in terms of environmental protection, and can be stored in a low-bulk state when not in use.
Moreover, it is an object to provide a corner pad that can be easily assembled at the time of use.

As shown in FIG. 6, the fold line 18 is bent, the inner substrate 19 and the inner substrate 19 are superposed on the bottom substrate 1, and the locking tongue pieces 20 projecting from the inner substrate 19 are attached to the inner plate 13.
This corner pad is assembled by engaging with the engaging recess 17 of.

At this time, as shown in FIGS. 4 to 6, the edge of the slit 21 comes into contact with the stepped portion 6 provided on the middle end plate 5.

It should be noted that anyone can easily assemble the cardboard by printing a number indicating the assembly order and an arrow indicating the folding direction on the surface of the cardboard in advance.

[0026]

[Effect of the Invention] Since the corner pad constructed as described above can be made by using paperboard such as corrugated board,
Since it does not cause pollution in the disposal process and can be reused, it is possible to provide a preferable corner pad in terms of environmental protection.

In addition, the bottom substrate 1, the middle substrate 23 and the inner substrate 1
One wall of this corner pad is constructed by using three sheets of 9 as a set, and similarly, the outer plate 3, the middle plate 15, and the inner plate 1 are formed.
Since the other wall is composed of three sets of 3 and one set of the outer end plate 9, the middle end plate 5, and the inner end plate 11, all the walls are formed to have an equal thickness. Can be done, and the material is not wasted.

Furthermore, when not in use, it can be stored in a flat state by stacking a plurality of flat plates, so that it can be stored in a low-volume state, so that the stock space is small and it is convenient for management.

In addition, by bending the crease lines to erect each plate and locking the locking tongue piece 20 in the locking recess 17,
Only the required number can be easily assembled and used without using any adhesive.
