JP-A-2001-341723

The corrugated cardboard box of the prior art is designed so that a carrier can put his or her fingers into the handle holes 17 to lift or carry the box. However, regarding the handle hole 17, only a structure in which a rectangular hole is bored horizontally is disclosed. Although such a structure is easy to manufacture and the cost can be reduced, it is easy for the carrier to hold and carry. No particular consideration is given to reducing the burden of labor by improving the efficiency of transportation and thereby improving the efficiency of transportation work. On the other hand, in the case of carrying heavy objects such as water, for example, the conventional structure with the handle hole 17 requires a great deal of labor for carrying, and there has been a demand for an improvement.

SUMMARY OF THE INVENTION An object of the present invention is to provide a corrugated cardboard box that reduces the labor burden of a carrier and improves the efficiency of the carrying work.

In order to achieve the above object, the present invention provides a corrugated cardboard box that is gripped and carried by the left and right hands of the carrier on the front side of the carrier, and has a front surface, a rear surface, a left surface, a right surface, an upper surface, and a lower surface. , the corrugated cardboard box that can be carried by the carrier in a first posture in which the rear surface is on the side of the carrier, the front surface is on the opposite side of the carrier, and the upper surface and the lower surface are substantially horizontal, wherein the left surface is provided with a hole. , a first left gripping hole for being gripped by the left hand, and a first right gripping hole formed in the right surface for being gripped by the right hand, the first left gripping hole and The first right gripping hole is provided so that the axis of each gripping hole is inclined upward when viewed from the carrier, and the first left gripping hole is inserted with the index finger and thumb out of the five fingers of the left hand. The first right grip hole is configured so that the middle finger, ring finger, and little finger can be inserted all at once without
Of the five fingers of the right hand, the index finger and thumb are not inserted, and the middle finger, ring finger and little finger are inserted together.

Due to the structure of the human skeleton, when the carrier puts his/her fingers into the grip holes and extends his/her hand toward the front almost horizontally (or slightly downward) to hold the cardboard box, the left and right hand The five fingers are not arranged horizontally, but arranged in such a positional relationship that they are inclined upward from the little finger to the index finger when viewed from the carrier. Correspondingly, in the present invention, the first left gripping hole and the first right gripping hole provided on the left and right surfaces are not provided horizontally, but are provided with an upward slope when viewed from the carrier. As a result, the carrier can lift the cardboard box by inserting the fingers of both the left and right hands into the first left gripping hole and the first right gripping hole in a comfortable and natural posture.

Also, when a person holds a cardboard box in front of them, the center of gravity is inevitably shifted to the rear of the body (weight is placed on the heels of the feet) in order to maintain balance. Structurally, the middle finger, ring finger, and little finger are easy to bend, but the thumb and index finger are difficult to bend, and if you try to bend them forcibly, you will get extra fatigue. In the present invention, the thumb and index finger, which are difficult to bend, are not inserted into the first left gripping hole and the first right gripping hole, and only the middle finger, the ring finger, and the little finger, which are easy to bend, are inserted into the first left gripping hole and the first right gripping hole. The above-mentioned pick-up is performed. This allows the carrier to support the weight of the corrugated cardboard box with only the minimum necessary force in a relatively relaxed state.

As a result, compared with the conventional structure in which horizontal gripping holes are provided only on the left and right surfaces, the labor burden on the transporter can be greatly reduced, and the efficiency of the transport work can be improved.

According to the present invention, it is possible to reduce the labor burden on the transporter and improve the efficiency of the transport work.
