Description

  The present invention relates to a folding container having a bent side wall in which a lower divided side wall that rotates with respect to a bottom wall and an upper divided side wall that rotates with respect to an upper frame are rotatably connected.

  Conventionally, as this type of folding container, one in which the hinge portion of the ridge connecting the lower divided side wall and the upper divided side wall is evenly arranged in the width direction of the bent side wall is known (for example, a patent) Reference 1).

JP-A-6-99975 (paragraph [0015], FIG. 1)

  However, in the above-described conventional folding container, since the hinge portion protrudes outward in the assembled state, the hinge portion becomes an obstacle when the outer surface of the folded side wall is labeled or the folding container is positioned on the transport line. Problems arise. In addition, in order to solve this problem, if the area having no hinge part is enlarged by reducing the number of hinge parts or shifting the position of the hinge part in the width direction of the folded side wall, Another problem arises that the connection of the side-divided side walls becomes unstable and the strength of the bent side walls decreases.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a folding container capable of suppressing a decrease in strength of the bent side wall while increasing a range not having the hinge portion in the width direction of the bent side wall. .

  In order to achieve the above-mentioned object, the invention according to claim 1 is characterized in that a pair of bent side walls facing each other among the side walls connecting the bottom wall and the upper frame are pivotally connected to the bottom wall. A side divided side wall and an upper divided side wall rotatably connected to the upper frame are connected to each other via a hinge part so as to be rotatable. In the assembled state in a box shape, the bent side wall is extended. In the folded state in which the folded side wall is folded inward in the folded state standing from the bottom wall and in a flat plate shape, a width of the folded side wall is provided between the upper divided side wall and the lower divided side wall. The folding container is provided at a position different from the hinge part in a direction, and is provided with a divided side wall engaging part that is overlapped in the inner and outer directions of the folding container and engaged with each other in the assembled state.

  According to a second aspect of the present invention, the divided side wall engaging portion includes a width movement restricting portion for restricting movement of the upper divided side wall with respect to the lower divided side wall in a width direction of the bent side wall, and an inner and outer direction of the folding container. The folding container according to claim 1, further comprising an inner / outer movement restricting portion that restricts movement of the upper divided side wall with respect to the lower divided side wall.

  The invention according to claim 3 is the folding container according to claim 2, wherein the inside / outside movement restricting portion is arranged closer to the center side in the width direction of the folding side wall than the width movement restricting portion.

  According to a fourth aspect of the present invention, in the folded side wall, a surface located outside the divided side wall engaging portion in the assembled state is flat. It is a folding container.

[Invention of Claim 1]
According to the first aspect of the present invention, the number of hinge portions is reduced, the position of the hinge portion is shifted in the width direction of the bent side wall, etc., and the range having no hinge portion in the width direction of the bent side wall is increased. In addition, the divided side wall engaging portion stabilizes the connection between the upper divided side wall and the lower divided side wall. Thereby, it becomes possible to suppress the strength reduction of a bending side wall, enlarging the range which does not have a hinge part in the width direction of a bending side wall.

[Invention of claim 2]
According to invention of Claim 2, it becomes possible to suppress the shakiness with respect to the lower divided side wall of the upper divided side wall in the width direction of the bent side wall and the inner and outer directions of the folded container.

[Invention of claim 3]
In the invention of claim 3, the inside / outside movement restricting portion is disposed closer to the center side in the width direction of the bent side wall than the width movement restricting portion. Here, since the dimensional error of the upper divided side wall and the lower divided side wall becomes smaller on the center side in the width direction of the bent side wall, the dimensional error of the inner and outer movement restriction portion can be made smaller than the dimensional error of the width movement restriction portion. It becomes. Thereby, it becomes possible to reduce the shakiness of the upper divided side wall in the inner and outer directions of the folding container. Further, the folding side wall has a larger amount of deformation in the inner and outer directions of the folding container at the center side than the outer side in the width direction. In the present invention, the inner and outer movement restricting portion is wider than the width movement restricting portion. Therefore, it is possible to suppress deformation of the bent side wall in the center in the width direction and to prevent the hinge portion from being broken or dropped off. Further, according to the present invention, since the width movement restricting portion is disposed on the outer side in the width direction of the bent side wall than the inner and outer movement restricting portion, the width movement restricting portion receives an impact received by the bent side wall from the outer side in the width direction. Thus, the load on the hinge portion can be reduced and the hinge portion can be prevented from falling off.

[Invention of claim 4]
According to the fourth aspect of the present invention, it is easy to label the outer surface of the bent side wall and position the folding container on the transport line.

It becomes possible to suppress the shakiness against.

  In addition, since the inner / outer movement restricting portion 65 is disposed closer to the center side in the width direction of the bent side wall 40 than the width movement restricting portion 61, the dimensional error of the inner / outer movement restricting portion 65 is smaller than the dimensional error of the width movement restricting portion 61. It becomes possible to reduce rattling of the upper divided side wall 41 in the inner and outer directions of the folding container 10. Further, the bent side wall 40 has a larger amount of deformation in the inner and outer directions of the folding container at the center side than the outer side in the width direction. In this embodiment, the inner and outer movement restriction portion 65 is more bent than the width movement restriction portion 61. Since it is arrange | positioned at the 40 width direction center side, it becomes possible to suppress the deformation | transformation of the width direction center side of the bending side wall 40, and to suppress the failure | damage and dropout of the hinge part H. In addition, since the inner / outer movement restricting portion 65 is disposed at a substantially central side between the side hinge portion H1 and the intermediate hinge portion H2, it is sandwiched between the side hinge portion H1 and the intermediate hinge portion H2 in the bent side wall 40. It is possible to suppress the deformation and dropout of the side hinge part H1 and the intermediate hinge part H2 by suppressing the deformation of the part. Further, in the present embodiment, the width movement restricting portion 61 is disposed on the outer side in the width direction of the bent side wall 40 with respect to the inner and outer movement restricting portion 65, so that the impact that the bent side wall 40 receives from the outer side in the width direction. It is possible to reduce the load on the hinge part H and prevent the hinge part H from falling off.

  Moreover, in this embodiment, since the part located in the outer side of the division | segmentation side wall engaging part 60 among the outer surfaces of the outer side opposing wall 53 is flat, a label is attached to the outer surface of the bending side wall 40, or a conveyance line is used. Positioning of the folding container 10 becomes easy.
