Problems solved by technology
[0005] In the collapsible container in which the above-mentioned locking member is arranged on the upper end portion of the side wall, the locking member is not arranged at the central part of the side wall, so there is a tendency of the central part of the side wall being assembled into a box shape to be assembled into a box shape. Problems with deformation of the folded container in the outside direction or the inside direction
[0006] In addition, when the locking member is arranged at two places, namely, the upper end portion and the middle portion of the side wall, the unlocking operation of the locking member must be performed twice, so there is a problem that the workability of the unlocking operation of the locking member is poor.

Embodiment Construction
[0019] Examples of the present invention will be described below, but the present invention is not limited to the examples unless the gist of the present invention is exceeded.
[0020] Reference numeral 1 denotes a bottom, and a long-side embankment (Dote) 1a is erected on opposite long sides of the bottom 1 , and a short-side embankment 1b is erected on opposite short sides of the bottom 1 . The height of the short-side bank portion 1b is configured to be higher than the height of the long-side bank portion 1a. Symbol 2 is the long side wall of the opposite long-side bank 1a connected to the bottom 1 by a suitable hinge member, and symbol 3 is the short side of the opposite short-side bank 1b connected to the bottom 1 by a suitable hinge member wall.
[0021] As shown in Figure 1, when folding as shown in Figure 3 from the state assembled into a box shape, first release the locking member described later, make the long side wall 2 fall down towards the bottom 1, and fold it...

The folding container has one pair of opposite side walls 2 hinged to a bottom 1, and the other pair of opposite side walls 3 hinged to the bottom 1. The container assembled as a box can be folded into a compact shape by folding down the one opposite side walls 2 toward the bottom 1, and then folding down the other opposite side walls 3 toward the bottom 1. The one side walls 2 is provided with lock members H, on each of which a plurality of fitting blocks h2 are formed. In correspondence to the fitting blocks h2, a plurality of fitting recessions 3d, into which the plurality of fitting blocks h2 are fitted, are formed on the other side walls 3.
Description
technical field [0001] The present invention relates to a collapsible container having a side wall hingedly connected to the bottom, and relates to such a collapsible container, which is assembled into a box-shaped state by causing one side wall opposite to the bottom to be folded down, and then The opposite side wall of the other side falls down and is superimposed on the opposite side wall of the one superimposed on the bottom so as to be foldable. Background technique [0002] Patent Document 1 discloses the above-mentioned collapsible container, in which the side wall that falls first and the side wall that falls backward is locked from the state assembled into a box shape by a locking member disposed on the upper end of the side wall, so that the The state of being assembled into a box shape prevents the above-mentioned side walls that fall first from falling toward the bottom. In addition, Patent Document 2 discloses a collapsible container in which such a locking mem...
