Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner pad used for packing packages.

[0002]

2. Description of the Related Art When transporting a package, for example, liquid crystal glass, about 20 liquid crystal glasses are stacked and packaged, and a corner pad is used at the time of packaging. This type of corner pad serves as a fixing jig for fixing the four corners of the liquid crystal glass and a spacer for ensuring a space between the liquid crystal glasses.

As shown in FIG. 13, a conventional corner pad 1 is formed integrally with an L-shape by injecting a foamed resin into a mold and straddles two supporting surfaces 2a, 2a having the L-shape. The groove 2b has a structure in which the grooves 2b are provided in parallel at a predetermined pitch.

When packaging the liquid crystal glass, as shown in FIG. 14, first, the two corner pads 1 are aligned side by side, the lower edge corners of the liquid crystal glass 3 are aligned with the grooves 2b of the corner pad 1, and the liquid crystal glass 3 is placed. Insert two adjacent edges 3a, 3b that sandwich the corner of the liquid crystal glass 3 into the groove 2b of the corner pad 1, fix the lower edge corners of the liquid crystal glass 3 with the two corner pads 1, and place a plurality of corners on the corner pad 1. Lean the liquid crystal glass 3 in the vertical direction.

Next, the upper edge corner of the liquid crystal glass 3 is similarly fixed by the two corner pads 1. As a result, the four corners of the liquid crystal glass 3 are fixed by the corner pads 1, and spaces are secured by the corner pads 1 between the adjacent liquid crystal glasses 3.

It is difficult to remove foreign matter inside, and inside this groove 2b, foreign matter is likely to be clogged, and this foreign matter floats the corners of the liquid crystal glass,
The corners of the liquid crystal glass are unstablely supported by the corner pads, and in extreme cases, the corners of the liquid crystal glass may be damaged.

Although the corner pad 1 is used repeatedly, it is bulky when the corner pad 1 is collected because it is an integrally molded product having an L-shaped outer shape, which results in loss of space for transportation. Will occur.

Further, since the corner pad 1 is integrally molded in an L-shape, the cavity of the mold has a three-dimensionally complicated shape, and the direction in which the foamed resin is fed into the cavity of the mold is a corner. Different for each support surface 2a of the pad 1,
There was a concern that the foamed resin would not be fed smoothly and the material on either one of the support surfaces 2a would become soft. The softer material of the support surface 2a is likely to be worn by the liquid crystal glass coming in and out, resulting in a difficulty in durability.

It is an object of the present invention to provide a corner pad that retains an L-shape during packaging and can be horizontally deployed during collection.

[0010]

In order to achieve the above-mentioned object, a corner pad according to the present invention comprises a pair of contact plates,
A corner pad having a hinge part, wherein the pair of contact plates is a flat plate shape made of foamed resin which is applied to the respective adjacent edges of the packaged article, and the adjacent edges of the corner are formed.
