Cardboard box

Abstract

A cardboard box includes: two pairs of opposed side walls; a bottom wall closing a region defined by the lower ends of the two pairs of side walls; and a lid covering an upper opening defined by the upper ends of the two pairs of side walls. At least one of the side walls can be opened and closed.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a cardboard box (corrugated box) used for containing and transporting goods, particularly to a large-sized cardboard box for containing and transporting tools or the like.[0003]2. Description of the Related Art[0004]In general, a cardboard box used for containing and transporting goods is so configured that a top wall thereof is openable, and goods are put into and taken out of the cardboard box through an upper opening formed by opening the top wall (see, for example, Japanese Patent Laid-open No. Hei 8-268471). As a cardboard box 1 for containing and transporting tools or the like, there is used a large-sized cardboard box measuring about one meter in length, about one meter in width and about one meter in height. In the case of using such a large-sized cardboard box, containing of goods into the cardboard box is carried out, for example, by two people, with one of them getting into th...

AI Technical Summary

Benefits of technology

[0006]Accordingly, it is an object of the present invention to provide a cardboard box which allows goods to be put into and taken out of the box easily, and, therefore, promises good working efficiency.

[0009]As above-mentioned, the cardboard box according to one aspect of the present invention includes the two pairs of opposed side walls, the bottom wall closing the region defined by the lower ends of the two pairs of side walls, and the lid covering the upper opening defined by the upper ends of the two pairs of side walls, wherein at least one of the side walls can be opened and closed. In containing goods into the cardboard box, therefore, the lid is detached to open the upper opening and, in addition, the at least one of the side walls which is configured to be openable and closable is opened to open a side portion of the box. In this state, a worker can get into the cardboard box through the opened side portion and perform the operation of containing goods into the box. In this case, since the upper opening is also open, the worker does not need to bend down when carrying out the operation.

[0010]In addition, at the time of taking out the goods contained in the cardboard box, the lid is detached to open the upper opening, and the at least one of the side walls that is openable and closable is opened to open the side portion, like in the case of containing goods into the box as above-mentioned. In this state, the worker can take out the goods contained in the cardboard box, through the opened side portion of the box. In this case, since the upper opening is also open, it is unnecessary for the worker to bend down when carrying out the operation. Thus, the upper opening is opened by detaching the lid, and the side portion is opened by opening the at least one of the side walls that is designed to be openable and closable. Therefore, the need to cut a side wall with a cutter to form an opening at the time of taking out the contained goods, as in the case of the cardboard box according to the related art, is eliminated. Accordingly, working efficiency is enhanced. Furthermore, since the cardboard box is not cut with a cutter, the cardboard box can be repeatedly used as a goods-delivery box, which is economical.

Problems solved by technology

The large-sized cardboard box as above-mentioned has a problem of poor working efficiency, since two people are required to contain goods into the box.

Since the cardboard constituting the large-sized cardboard box has a thickness of 1 to 2 cm, however, the operation of cutting the side wall with a cutter to form the opening requires considerable time and effort.

Thus, there is a problem of poor operating efficiency.
