Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a corrugated cardboard corner member which stands up along four corners of an outer box and holds the contents through the corners of the contents.

[0002]

[Prior art]

 As shown in FIG. 6, for example, a conventional corner member is formed by embedding a wooden reinforcing material 13 in a part of a body 12 made of an angled foam still roll.

[0003]

[Problems to be solved by the device]

 Since the above corner members are made of Styrofoam, there is a problem of pollution at the time of waste incineration.

In order to solve this pollution problem, a corner member made of corrugated cardboard is known, but there is a problem in strength.

An object of the present invention is to provide a corrugated cardboard corner member which has high strength and does not cause pollution problems when discarded and incinerated.

[0006]

[Means for Solving the Problems]

 According to the present invention, in a corrugated cardboard corner member which stands up along four corners of an outer box and holds the contents through the corners of the contents, a longitudinal direction end of a long multi-layer corrugated cardboard is provided. A first fold line on the center line and a second fold line orthogonal to the first fold line are engraved in the same portion in the same bending direction, and the damper is provided on both sides of the center line other than the first fold line. A plurality of punched portions having a width of approximately the thickness of the cardboard are punched in a zigzag shape, bent from the second fold line, and then bent in the opposite direction from the center line. It forms the contact surface.

It is preferable to use two or three layers of corrugated paper as the above-mentioned multi-layer corrugated paper.

[0008]

[Action]

 In the corrugated cardboard corner member configured as described above, the multi-layer corrugated cardboard is bent into an L-shape, and both end portions thereof are bent and reinforced outward, so that a large strength can be obtained. In addition, it is very easy to assemble, and no adhesive or the like is required for lamination.

Furthermore, when discarded, it can be easily incinerated and has no pollution.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, corner members 1 made of multi-layer corrugated paper are set up along one corner inside an outer box 10 made of corrugated cardboard, and inside the corner members 1, The contents 11 are stored.

FIG. 2 shows a base paper 2 in which the corner member 1 is developed. The base paper 2 is made of a multi-layer (two layers in the example of FIG. 1, but may be one layer or three or more layers) corrugated cardboard paper.

The base paper 2 is formed of a long paper having a width W of, for example, 163 mm and a length L of, for example, 630 mm. In the longitudinal end portion 1a of the base paper 2, that is, the portion having a length L1 (for example, 80 mm) from the end, the first folding line 3 on the center line LC of the base paper 2 separates both side portions (folding direction). It is engraved in the direction of bending downward on the plane of the line 3). And the 2nd cutting line 4 orthogonal to this 1st folding line 3 is carved in the same direction.

On the other hand, widths W1 and W2 are approximately equal to the thickness of the base paper 2 on both sides of the intermediate portion 1b (portion of length L2) other than the first folding lines 3 and 3 of the center line LC. (For example, 18 mm and 15 mm, respectively) A large number (5 in the illustrated example) of the cutouts 5 to 9 are staggered, that is, the cutouts 5, 7 and 9 are on the left side of the center line LC and the cutouts 6 and 8 are on the right side. Each is formed by punching. Further, tapered portions 6b, 6c, 8b, 8c are formed above and below the one of the punched portions, for example, the right punched portions 6, 8, and the tapered portion 6b has a lower surface 5a and a tapered portion when bent as described later. 6c is locked by engaging the upper surface 7a, the tapered portion 8b with the lower surface 7b, and the tapered portion 8c with the upper surface 9a.

When assembling the corner member 1, as shown in FIG. 3, the end portions 1a, 1a are bent from the second folding lines 4, 4.

Next, as shown in FIG. 4, the intermediate portion 1b is bent in a direction opposite to the second fold line 4 with the center line LC as a boundary, that is, in a direction approaching each other. Then, for example, the projecting portions 7a (Fig. 2) facing each other are fitted into the cutout portion 7 and are bent until they become an angle shape as a whole, and the intermediate portion 1b is reinforced by the end portions 1a, 1a to form a strong corner. The member 1 is obtained.

As shown in FIG. 1, when the corner member 1 is erected along four corners inside the outer box 1 and the contents 11 are stored therein, the end portions 1a, 1a of the corner member 1 are The inner surface of the intermediate portion 1b abuts on the inner surface of the corner portion of the box 10, and the outer surface of the corner portion of the content 11 abuts, so that the content 11 is securely held in the outer box 10 by providing a gap C therebetween.

[0018]

[Effect of device]

 Since the present invention is configured as described above, it is possible to provide a corner member having high strength and having no pollution problem at the time of waste incineration.
