Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an internal cushion used for a cardboard box for packing.

[0002]

2. Description of the Related Art When a plurality of products are packed in a cardboard box and packed, the products are protruded from the boxes, and the products are hit each other during transportation or transportation so that the products do not hit each other and are not damaged. With an internal cushion. Cardboard and Styrofoam as these cushions and partitions,
Materials such as pneumatic vinyl sachets are used,
The material and shape of the cushion used depend on the shape of the product.

For example, an output part at one end of a main body, such as an electric drill of a power tool, has a small diameter and a power cable is arranged at the other end. When packing a plurality of packages, the internal cushion 10 having a shape as shown in FIG. 5 was used.

As shown in FIG. 1, the inner cushion 10
A plurality of protrusions 9 and notches 3 were formed on both sides in the longitudinal direction, and a plurality of bends 4 were performed from the vicinity of both ends to form a rectangular tube on both sides to form an internal cushion.

FIG. 6 shows a conventional internal cushion 10 placed in a packing box 6 and a product 7 stored therein. By using the internal cushion 10 having such a shape, the front part and the rear part of a product such as a power tool can be held at a plane bent at a right angle, and movement in the front-rear direction can be prevented. Prevents jumping out of the packing box. In addition, since a space is formed at a place where the power cable is attached, the cable can be stored at this place.

[0006]

However, since the conventional internal cushion has its longitudinal end portion cut off, the rectangular cylinder is deformed by springback by releasing the hand after bending into a rectangular cylinder. In addition, since the bent portions of the corner bent portions vary, as shown in FIG. 7, each square tube shape is deformed in a different manner.

As described above, since the rectangular tube shape is deformed and the entire portion bent into the rectangular tube shape cannot be held by hand, it is difficult to store the cushion in a box.
There is a problem that this storage takes time.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide an inner cushion for a packing box that can be easily folded and stored in the packing box.

[0009]

A plurality of oblong holes having the same dimensions are formed in the vicinity of both sides in the longitudinal direction of a rectangular cardboard sheet so as to be elongated in the longitudinal direction.
A notch of the same length is formed in the center direction from both sides in the longitudinal direction of the plurality of oblong holes, and a first bend is performed along an end side of the plurality of oblong holes to form an oblong hole. In parallel with the first bending, and, toward the center direction, perform the second and third bending from both sides, at the notch end, perform a fourth bending in the opposite direction to the bending, on both sides The problem is solved by forming an inner cylinder that is easy to bend and to be stored in a packing box by forming a square tube shape.

[0010]

When the inner cushion provided with a plurality of rectangular holes and cuts as shown in FIG. 2 is bent four times from both ends, rectangular cylinders are formed on both sides as shown in FIG. When the hand is released from the cushion that is bent in this manner, the cushion returns to its original position due to springback, and the rectangular cylinder is deformed.

When the cushion is stored in the packing box, the bent portions on both sides are held by hand so that the rectangular tube shape is not deformed. Therefore, it can be easily stored.

[0012]

FIG. 1 is a perspective view of an internal cushion according to one embodiment of the present invention, and FIG. 2 is a perspective view of an internal cushion according to one embodiment of the present invention. FIG. 3 is an exploded view of the cushion, FIG. 3 is a plan view in which a product is stored using an internal cushion according to an embodiment of the present invention, and FIG. 4 is a view of FIG.

Referring to FIGS. 1 and 2, an inner cushion 1 is shown.
A plurality of rectangular holes 16 of the same shape are arranged on both sides in the longitudinal direction of a rectangular cardboard sheet with the same dimensions as the sides, and the rectangular hole 16 is located at the center from both sides in the longitudinal direction. A notch 3 is formed in the direction.

As shown in FIG. 1, the cardboard sheet in which the rectangular holes 16 are arranged is subjected to the first bending 12 along one side of the rectangular holes 16 near the ends, and further, to the center. The oblong hole 16 is bent twice 13 and 14 toward the end, and a fourth bend 15 is formed in the back of the cut portion 3 in the direction opposite to the above-mentioned bending, and is formed in a rectangular cylindrical shape.

By bending as described above, a plurality of prisms are formed on both sides. Numeral 5 denotes an end portion, which is bent so that the end portion 5 comes to the position shown in FIG. 1. The inner cushion thus bent is stored in a packing box 6 to form a rectangular tube-shaped portion. The end 5 abuts against the fourth bent portion 15 even if an external force is applied to the second bent portion 15 so that the end portion 5 is held and hardly deformed.

FIGS. 3 and 4 show a case where the inner cushion 1 is housed in the packing box 6 and the same number of U-shaped frames 8 as the products 7 are housed so that adjacent products do not come into contact with each other. Thereafter, the product 7 is stored.

[0017] By storing in this manner, there is no movement in the front-back and left-right directions, and furthermore, by putting a cardboard-made pad on the upper surface and closing the upper lid and packing, the movement in the vertical direction is also reduced. Can be prevented.

As described above, the internal cushion 1 according to the present invention is provided.
Compared with the conventional product, when bending the oblong hole portion 16 and the cut portion 3, since the end portions 5 are connected, it is possible to bend one side at the same time, and the bending is easy and short. Can bend in time. Further, if one portion is held after bending into a rectangular tube shape, the shape of the rectangular tube is stabilized, so that it is easy to insert the internal cushion 1 into the packing box 6.

The shape of the product is not limited to the electric tool.
The inner cushion 1 according to the present invention can be used in a case where one end is thinner than the center and a power cord is attached to the other end, or a case where both ends are thinner than the center.

The number of oblong holes is not limited to the embodiment, and the number may be arbitrary. In order to increase the strength of the internal cushion, the direction of the corrugate 11 is the same as the longitudinal direction.

[0021]

As described above, the inner cushion for a packing box of the present invention can be bent at the same time, the bending becomes easy, the insertion into the packing box is easy, and the packing work efficiency is improved. I do.
