Each short side bank 10b, which is taller than the long side bank 10a, comprises a vertical exterior wall 10b1, a vertical interior wall 10b2, and a top 10b3, where a gripper recession 40 is formed on the vertical exterior wall, to form a reversed U-shape. <P>COPYRIGHT: (C)2004,JPO

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding container capable of folding a side wall disposed so as to surround a bottom portion so as to overlap the bottom portion. 2. Description of the Related Art Conventionally, as shown in FIG. 8, a bottom portion 1 having a substantially rectangular planar shape is hinged to a long side bank portion 1a having a relatively low height. A side wall 2 and a short-side bank 1b, which also has a height opposite to the bottom 1 above.
A folding container consisting of a short side wall 3 hinged to the front side is known, and in such a folding state, in a folded state, the long side wall 2 which has been folded down first is overlapped on the bottom 1. Further, the opposing short side wall 3 which is folded down later is placed on the long side wall 2 which is folded down first and overlapped with the bottom portion 1 so as to be folded into a compact state having a low height. ing. [0003] When the above-mentioned conventional folded containers are stacked, a short-side bank portion 1b having a high height at the bottom portion 1 of the folding container located above.
Are stacked in such a manner that they are placed on the short side bank 1b of the bottom 1 of the folding container located below. [0004] As shown in FIG. 8, when the folding containers having the above-described configuration are stacked in a folded state, as shown in FIG. 8, the bottom portion of the folding container located at the top is obtained. Since no gap is formed between the short side bank 1b of the bottom side of the folding container 1 and the short side bank 1b of the bottom 1 of the folding container located below, when the stacked folding containers are lifted, the bottom 1 On the short side bank 1b side, there is no handle recess into which a hand can be inserted, so that there is a problem that the workability of taking out the folded containers stacked in a folded state is poor. Since there is a predetermined gap on the long side bank 1a side of the bottom 1, put a hand under the long side bank 1a of the bottom 1,
It is possible to lift the folded container by holding the long side bank 1a with both hands, but it is more stable to hold the short side bank 1b of the bottom 1 of the folding container with both hands and lift it. It can be lifted and carried in a stable state. An object of the present invention is to solve the problems of the above-mentioned conventional folding container. [0006] In order to achieve the above-mentioned object, the present invention provides a bottom part, a long side wall connected to a long side bank part opposite to the bottom part via a hinge member, Similarly, the bottom portion includes a short side wall connected to the opposite short side bank portion via a hinge member, and in the folded state, the long side wall is folded on the bottom portion so as to overlap the bottom portion. In the folding container configured so that the side wall is folded, the short side bank portion, which is higher than the long side bank portion, is formed into an inverted U shape including a vertical outer wall portion, a vertical inner wall portion, and a top portion. In addition, a recess for a handle is formed in the vertical outer wall. An embodiment of the present invention will be described below, but the present invention is not limited to the embodiment unless it exceeds the gist of the present invention. Reference numeral 10 denotes a bottom having a substantially rectangular planar shape. A long side wall 20 is connected to the opposite long side bank 10a of the bottom 10 via a suitable plurality of hinge members H, and a short side bank 10b of the bottom 10 is opposite to the long side bank 10a. The short side wall 30 is connected via an appropriate plurality of hinge members H. The height of the long side bank 10a of the bottom 10 is formed lower than the height of the short side bank 10b. In order to fold the box-shaped folded container shown in FIG. 1 as shown in FIG. 3, first, as shown in FIG. The side wall 20 is tilted in the direction of the bottom 10 and overlaps the bottom 10, and then the short side wall 30 is tilted in the direction of the bottom 10,
It is configured such that it can be folded by being superimposed on the long side wall 20 which is superimposed on the bottom portion 10. As shown in FIG. 4, a short side bank portion 10b having a height of the bottom portion 10 located between the hinge members H includes a vertical outer wall portion 10b1, a vertical inner wall portion 10b2, and a vertical outer wall portion. It is formed in an inverted U-shape composed of an upper end of 10b1 and a horizontal top portion 10b3 connecting the upper end of the vertical inner wall portion 10b2. A well-known fitting portion 10c that can be fitted into the opening of the folding container assembled in a box shape is provided on the rear surface of the bottom portion 10 so as to project therefrom. The short side bank 1 located in the central region of the short side bank 10b of the bottom 10 and between the hinge members H
In the vertical outer wall portion 10b1 constituting 0b, a handle concave portion 40 formed to be recessed in the direction of the vertical inner wall portion 10b2 is formed over a width and a height enough to allow a hand to enter. In the present embodiment, the handle concave portion 40 is formed in the vertical outer wall portion 1.
0b1, a horizontal ceiling 10b3 connecting the upper end of the vertical inner wall 10b2, a substantially horizontal lower plate 40a connecting the vertical outer wall 10b1 and the vertical inner wall 10b2, a vertical outer wall 10b1, and the vertical inner wall 10b2. And is surrounded by an opposing side plate 40b. The handle recesses 40 are respectively formed in the opposite short side bank portions 10b. As shown in FIG. 6, when the folding containers constructed as described above are folded and stacked, as shown in FIG. 6, the central portion of the opposite short side bank portion 10b of the bottom portion 10 is formed. In the area, respectively, the handle recess 40
Is formed, the user can easily and easily lift the folded container by putting his or her hand into the holding recess 40 and lifting it. The embodiment shown in FIG. 7 shows a long side bank 10a which is lower in height than the short side bank 10b of the bottom 10.
However, similarly to the above-described short side bank 10b, when formed in an inverted U-shape, the short side bank 10b is also provided in the central region of the long side bank 10a. A recess 50 for a handle similar to the recess 40 for a handle is formed. When the height of the short side wall 30 is high, in other words, when the depth of the folding container assembled in a box shape is deep, the upper end 30a of the opposite short side wall 30 in the collapsed state. There may be no gap between them. In this manner, the upper end portions 3 of the opposing short side walls 30 in the collapsed state.
0a, there is no gap between the bottom 10 and the bottom
Between the long side bank portion 10a of the bottom side and the long side bank portion 10a of the bottom portion 10 of the folded container in a stacked state, which is located below, and a sufficient gap for allowing a hand to enter. May not exist. Even in such a case, as described above, by forming the handle concave portion 50 in the central region of the long side bank portion 10a, the hand is inserted into the handle concave portion 50 and the long side of the bottom portion 10 is formed. Side bank 10a
To hold the folded container in the folded state. Since the present invention has the above-described configuration, the following effects can be obtained. The recess for the handle is formed in the short bank on the short side constituting the bottom, so that the folded container in the desired folded state can be changed from the stacked folded container in the stacked state. It can be lifted and taken out easily and stably.
