Problems solved by technology

[0004] When releasing the above-mentioned lock mechanism, it is necessary to separately operate a pair of unlock members arranged at both ends of the long side wall, so there is a problem that the operability of the operation of the lock release mechanism is not good.
[0005] In addition, there is a problem that since the elastic strip for reset formed on the unlocking member is exposed outside the collapsible container assembled into a box shape, it is easy to be damaged, and the appearance of the collapsible container is also unsightly.

Embodiment Construction

[0019] Hereinafter, although the Example of this invention is demonstrated, unless the meaning of this invention is exceeded, it is not limited to this Example at all.

[0020] The overall structure of the present invention consists of the bottom 1, the opposing long side walls 2 hinged on the bottom 1, and the opposing short side walls 3 also hinged on the bottom 1, from the box-shaped state shown in Figure 1 when assembled , first, as shown in Figure 2, the short side wall 3 is laid down and overlapped on the bottom 1, and then the long side wall 2 is brought down and overlapped on the short side wall 3 overlapping with the bottom 1, thus, Such as image 3 As shown, the collapsible container can be folded into a compact form with a small height. Additionally, from image 3 In the state shown, by erecting the long side wall 2 approximately vertically and then erecting the short side wall 3 approximately vertically, as shown in FIG. 1 , the folded collapsible container can be ...

Abstract

To release adjacent walls from a locked state by one step of an operating member to improve workability in releasing a lock. A lock releasing mechanism to release adjacent side walls 2, 3 from a locked state is composed of a pair of pushout levers 4 and one operating member 5. Cam shafts 5e, which engage with respective engaging short shafts 4b of the pushout levers, and elastic plate strips 5c, which apply upward energy to the operating member, are formed on the operating member. Locking ribs 3h, on which the elastic plate strips are placed, are formed on the side wall on which the operating member is fitted. (C)2005,JPO&NCIPI.

Description

technical field [0001] The invention relates to a collapsible container in which a side wall disposed around a bottom can be folded so as to overlap the bottom. Background technique [0002] In the past, it is well known that a collapsible container is composed of a long side wall and a short side wall. The long side wall is connected to the opposite long side of the bottom of a substantially rectangular planar shape by a hinge member. Similarly, the short side wall is connected by a hinge member. On the opposing short sides of the above-mentioned bottom, the long side wall and the short side wall can be assembled into a box shape by erecting the long side wall and the short side wall approximately perpendicular to the bottom. In addition, when folding, the long side wall is folded as if overlapping the bottom. and the short side wall, in the state of being assembled into a box shape, lock each other with a locking mechanism, so that the long side wall or the short side wall...
