Description

  The present invention relates to a corner pad for packaging.

Conventionally, the corner pad of patent document 1 is proposed as this kind of corner pad. This corner pad is formed by folding a single cardboard sheet to protect the corners of the package object.
JP-A-11-59721

  The corner pad described in Patent Document 1 has a complicated folding operation and is difficult to form quickly.

  Further, simply fitting the corner pad described in Patent Document 1 into the corner of the packing object has a disadvantage that the corner pad falls off during conveyance.

  Furthermore, since the corner pad described in Patent Document 1 has a protruding shape at the corner, there is an inconvenience that if a soft packaging material such as a film or paper is packed after being fitted, it is torn.

  Accordingly, the present invention has been devised to solve the above-mentioned problems, and aims to provide an inexpensive corner pad that can be formed from a single corrugated cardboard sheet by a simple folding operation, has corners that are flat, and does not fall off easily. To do.

  In order to achieve the above-mentioned object, the first means of the present invention is to provide the outer plates 2 and 3 on the left and right sides through the side plate 1, the inner ceiling plate 4 above and below the outer plate 2, and the other outer plate 3. The outer ceiling plate 5 is extended vertically, the folding lines 6 to 9 are bent so that the outer ceiling plate 5 overlaps the outer surface of the inner ceiling plate 4, and the support plate 11 extended from the outer ceiling plate 5 is used as the inner ceiling plate. The inner ceiling plate 4 and the outer ceiling plate 5 are connected to each other by being folded on the inner surface of 4.

  The second means is that the support plate 11 extended from the outer ceiling plate 5 is bent along the longest side of the inner ceiling plate 4, so that the flexible support plate 11 is formed inside the corner pad. The repulsive force of the eleven folding line 12 acts to fix the packing object.

  In the third means, the outer top base plate 5 shares at least one support side 10 having a bowl shape or a wavy shape with the adjacent inner top base plate 4, and the support side 10 overlaps the folding line 9 to form the side plate 1. .

  The fourth means has the outer plates 2 and 3 provided with the recesses 14 on the opposite side of the side plate 1, and forms the recesses 11a by intersecting both ends of the outer ceiling plate 5 and the support plate 11 at right angles. And

  According to claim 1 of the present invention, the folding lines 6 to 9 are bent so that the outer ceiling plate 5 overlaps the outer surface of the inner ceiling plate 4, and the support plate 11 extending from the outer ceiling plate 5 is attached to the inner surface of the inner ceiling plate 4. It is possible to provide a corner pad that can be formed by a very simple folding operation in which it is folded and connected so as to overlap with each other. Since it can be transported in a blank state when not in use, it has good loading efficiency, excellent storage properties, and can be provided simply by punching the blank for manufacturing, so that it is excellent in terms of cost. Further, since the inner ceiling plate 4 and the outer ceiling plate 5 overlap each other and the support plate 11 is folded on the inner surface of the inner ceiling plate 4, the strength is sufficient. Furthermore, since no adhesive is required, it can be easily disassembled and disposed of after use.

  In Claim 2, since the support plate 11 which can be bent is formed inside the corner pad, and the repulsive force of the folding line 12 of the support plate 11 acts on fixing to the packing object, the corner pad is the packing object. It can be made difficult to fall off.

  According to the third aspect of the present invention, the side plate 1 is formed by overlapping the saddle-like or wavy support side 10 on the folding line 9, so that the support plate 10 prevents vibration of the inner ceiling plate 4 when the corner pad is formed, and is stable. The side plate 1 can be formed.

  By forming the side plate 1 in claim 3 and providing the recesses 14 and 11a in the outer plates 2 and 3 and the support plate 11 in claim 4, respectively, a corner pad having no protrusion at the corners is formed, and the film is formed on the corner pad. Even with soft packaging materials such as paper and paper, breakage at the corners can be prevented.

  In this way, according to the present invention, a strong corner pad can be formed by an extremely simple folding operation, and after use, it can be easily disassembled and disposed of. It has various practically beneficial effects that it cannot be broken.

  In the best mode of the present invention, the adjacent inner top plate 4 and outer top plate 5 having a saddle-like or wavy support side 10 are extended from the outer plates 2 and 3 having the recesses 14. The side plates 1 are formed by folding the folding lines 6 to 8 so that the support side 10 overlaps the folding line 9. Thereafter, the outer ceiling plate 5 is bent so as to overlap the outer surface of the inner ceiling plate 4 according to the folding curve 9, and the support plate 11 extending from the outer ceiling plate 5 and having the recesses 11 a at both ends is folded to the inner surface of the inner ceiling plate 4. By overlapping, the inner ceiling plate 4 and the outer ceiling plate 5 are connected to form a corner pad having a support plate 11 having a repulsive force inside. The original purpose is achieved by fitting this into the corner of the packing object.

  The basic structure of the corner pad of the present invention is a single blank made of a corrugated cardboard sheet, and is formed simply by folding without using an adhesive or the like.

  This blank is provided with outer surfaces 2 and 3 having recesses 14 through side plates 1, and an inner ceiling plate 4 is provided above and below the outer surface 2, and an outer ceiling plate 5 is provided above and below the other outer surface 3. A flexible support plate 11 having recesses 11 a at both ends is extended from the folding line 12 to the outer ceiling plate 5. The inner ceiling plate 4 and the outer ceiling plate 5 adjacent to each other share a cutting line, the cutting line has a bowl shape or a wave shape, and at least one support side 10 is provided (see FIG. 1).

  The corner pad of the illustrated example folds the bent piece 13 extending from the upper and lower sides of the side plate 1 inward and folds according to the folding curves 6 to 8 so that the support side 10 overlaps the folding curve 9 to form the side plate 1. (See FIG. 2). Further, by folding the outer ceiling plate 5 along the folding line 9, the outer ceiling plate 5 overlaps the outer surface of the inner ceiling plate 4, and by bending the supporting plate 11 along the folding curve 12, the flexible supporting plate 11 can be bent. The corner pad is formed so that the inner top plate 4 and the outer top plate 5 are connected to each other, and the repulsive force of the folding line 12 acts to fix the packing object (see FIG. 3).

  The method of use of the present invention is fixed by fitting the support plate 11 so that the support plate 11 is positioned inside the corner pad and is pushed into the corner of the packing object.

  Each configuration in the illustrated example is only one embodiment of the present invention. For example, the same corner pad can be formed without extending the bent piece 13 from the side plate 1. In addition, the material of the sheet can be changed to another material such as a synthetic resin material, and can be freely changed without departing from the gist of the present invention.

It is an expanded view which shows one Example of this invention. It is a perspective view which shows the assembly order of FIG. It is a perspective view which shows one Example of this invention.
