Example

The embodiments of the present invention will be described below, but as long as the gist of the present invention is not exceeded, it is not limited by the embodiments.

C is a collapsible container, and the collapsible container C includes a bottom 1 having a substantially rectangular planar shape, long sidewalls hinged on opposite long side banks 1a of the bottom 1, and opposite short side banks hinged on the bottom 1 In the short side wall 3 on the portion 1b, the height of the long-side bank 1a of the bottom 1 is lower than the height of the short-side bank 1b.

As shown in Fig. 1, when folding and assembling into a box-shaped collapsible container C, as shown in Fig. 2, the long side wall 2 in the roughly vertical state is brought down to a roughly horizontal state, and then the short side wall 3 in the roughly vertical state is laid down. It can be folded into a low and compact state as shown in FIG. 3 by laying down in a substantially horizontal state and overlapping the previously laid down long side wall 2 . Or, from the folded state shown in FIG. 3, the short side wall 3 in the substantially horizontal state is first erected approximately vertically as shown in FIG. Box-shaped as shown in Figure 1.

P is a partition member that can be accommodated in the collapsible container C, and the partition member P consists of a rectangular thin-plate-shaped horizontal plate p1 that is approximately the same in size as the planar shape of the bottom 1, and extends upward along the long side of the horizontal plate p1 perpendicular to the horizontal plate p1 The thin plate-shaped folded side panel p2 has a substantially U-shaped base P', and the opposite folded side panel p2 connected to the long side of the horizontal plate p1 is configured so that P3 rotates relative to the horizontal plate p1. As an example, by forming thin-walled parts or intermittent perforations (misin mesh) etc. on the connection part p3 of the horizontal board p1 and the folded side board p2, the folded side board p2 can be formed at the connection part p3 of the horizontal board p1 and the folded side board p2. p3 rotates relative to the horizontal plate p1.

p4 is a substantially prism-shaped central spacer installed on the horizontal plate p1 located in the center between the opposite folded side plates p2 approximately parallel to the folded side plates p2, and p5 is the horizontal plate p1 installed on the folded side plates p2 Substantially prismatic side spacers in the upper region of . The inclined surface p5a is formed by cutting off the lower corner of the side spacer p5 on the side of the center spacer p4 as necessary.

On the central spacer block p4 attached to the horizontal plate p1 constituting the spacer member P and the side spacer block p5 attached to the opposite folded side plate p2, recesses of predetermined shapes are respectively formed according to the articles held by the spacer member P. p4a, p5b.

The height H1 of the folded side panel p2 of the partition member P having the above structure erected in a substantially vertical state is higher than that of the long side bank 1a lower than the height of the bottom 1 when the partition member P is installed in a box-shaped foldable container C. The inner height (height from the upper surface of the bottom 1 to the upper surface of the long-side bank 1a) H2 is high.

The embodiment shown in FIG. 1 and FIGS. 4 to 7 shows an example of holding a steering wheel S of an automobile or the like. In order to hold the lower end s1 of the steering wheel S, the central spacer p4 is formed with a concave portion p4a that can be inserted above the lower end s1 of the steering wheel S and open left and right, and in order to hold the side s2 of the steering wheel S, the side spacer p5 A concave portion p5b that is open above the side portion s2 into which the steering wheel S can be inserted and on the side of the central spacer p4 is formed.

After the collapsible container C having the above-mentioned structure is assembled into a box shape, the spacer member P having the above-mentioned structure is arranged in the collapsible container C assembled into a box-shape in such a way that the folded side panels p2 and the horizontal panels p1 Vertically, at the same time make the folding side panel p2 be positioned at one side of the long side wall 2 that is laid down first when folding and assembling the collapsible container C into a box shape. Then, the steering wheel S as an example of an article is held by inserting its lower end s1 into the recess p4a of the central spacer p4 and inserting the side s2 of the steering wheel S into the recess p5b of the side spacer p5. In this way, a predetermined number of steering wheels S are held by the partition member P disposed in the folded container C assembled in a box shape.

After the collapsible container C containing the partition member P holding the steering wheel S as an example of an article is transported to a predetermined transport location, the steering wheel S is taken out of the collapsible container C. Then, after all the steering wheels S are taken out, the box-shaped foldable container C is folded and assembled as described above. In this embodiment, although the long side wall 2 is brought down first during the folding operation, since the partition member P is such that the foldable side panel p2 that can be folded relative to the horizontal plate p1 through the connecting portion p3 is located on the long side that is brought down first. The wall 2 is disposed on one side, and the height H1 of the folded side panel p2 in a state of standing approximately vertically is lower than the height of the bottom 1. The inner height of the long side bank 1a (from the upper surface of the bottom 1 to the long side) The height (height) H2 of the upper surface of the side bank portion 1a is high, and since the long side wall 2 is brought down toward the bottom 1, the folded side panel p2 also falls in the direction of the horizontal plate p1, so it is not necessary to assemble a box-shaped folded container Taking out the partition member P from C, the partition member P can also be folded simply by putting down the long side wall 2 in the direction of the bottom 1, so that not only the workability of folding the collapsible container C is improved, but also the spacer member P is not required to be accommodated. place. In addition, the height H3 of the folded spacer member P is formed to be equal to or less than the inner height (height from the upper surface of the bottom 1 to the upper surface of the long-side bank 1a) of the long-side bank 1a where the height of the bottom 1 is low. .

In addition, as described above, by forming the inclined surface p5a at the lower corner of the side spacer p5 of the spacer P on the side of the center spacer p4, the folded side panel p2 is folded toward the side of the horizontal plate p1 as shown in FIGS. 6 and 7 . direction, since the height H3 of the folded partition member P can be reduced, the height of the long side bank 1a lower than the short side bank 1b of the bottom 1 of the foldable container C can be reduced, and the assembled box can be reduced. The height of the collapsible container C in shape and the height of the collapsible container C in the folded state. Therefore, it is possible to reduce the accommodation space for accommodating the collapsible container C assembled in a box shape and the collapsible container C in a folded state.

FIG. 8 shows another example of the partition member P. As shown in FIG. The partition member P of this embodiment is a member for holding the bottle B, and a concave portion p4b extending longitudinally and having a curvature radius substantially the same as that of the body b1 of the bottle B is formed on both side wall surfaces of the central partition block p4. Also, a concave portion p5c having a curvature radius approximately the same as that of the body b1 of the bottle B is formed on the wall surface of the side spacer p5 on the side of the central spacer p4. The formed recesses p4b face each other. The method of arranging such a partition member P in the collapsible container C assembled in a box shape and the method of folding the collapsible container C after discharging the bottle B are the same as those in the above-mentioned embodiments, and therefore detailed description thereof will be omitted.

In the embodiment shown in FIGS. 9 and 10 , a pair of protruding barrier ribs 1b2 are protrudingly provided at a predetermined interval on the inner wall surfaces 1b1 of the opposing short-side banks 1b of the bottom 1 . The top 1b2' of the barrier rib 1b2 is slightly higher than the height H3 of the partition member P after folding. During the operation of folding and assembling the collapsible container C into a box shape, the long side wall 2 laid down at first abuts against the top 1b2' of the barrier rib 1b2, and the long side wall 2 laid down does not touch the folded partition member P. collide. By adopting such a structure, when the collapsible container C is folded and assembled into a box shape, the partition member P does not collide violently with the long side wall 2 and does not damage the partition member P or the long side wall 2 .

And, although as mentioned above when folding and assembling into the box-shaped collapsible container C, first a pair of opposite long side walls 2 are turned upside down toward the direction of the bottom 1, but as shown in Fig. 7 and Fig. 10, on the long side The outer wall surface 2a of the wall 2 (when the vertical rib 2b and the horizontal rib 2c are formed on the outer wall surface 2a, including the imaginary outer wall surface formed by the top ends of the vertical rib 2b or the horizontal rib 2c) is formed with an edge along the entire predetermined height. The recessed region 2 d extending in the width direction of the long side wall 2 . Not only is such a recess region 2d formed on the long side wall 2, but also the top inner corner portion 2e of the upper long side wall 2 is mounted on the recess region 2d formed on the outer wall surface 2a of the lower long side wall 2. The overlapping height of the long side wall 2 on the upper side and the long side wall 2 on the lower side can be reduced (vertical height in the direction), therefore, the height of the foldable container C in the folded state can be further reduced.

Since the folded side panel p2 of the partition member P arranged in the folded container C assembled into a box shape as described above is located on the side of the long side wall 2 first laid down from the state assembled into a box shape, the partition member P will not Since it becomes an obstacle to the rotation toward the bottom 1 of the long side wall 2 that was first laid down, the collapsible container C assembled in a box shape can be folded without taking out the partition member P from the collapsible container C assembled in a box shape.

When folding and assembling the collapsible container C into a box shape, since the inner wall surface 1b1 of the short side embankment 1b of the bottom 1 of the short side wall 3 which is hinged and then laid down is protrudingly provided with the first long side The barrier rib 1b2 against which the wall 2 is abutted, so that the long side wall 2 which is first laid down does not abut against the folded partition member P, thus preventing the partition member P The partition member P or the long side wall 2 is damaged by colliding with the long side wall 2 .

Since the present invention has the configuration described above, the following effects are produced.

Since the folded side panels of the partition member arranged in the foldable box-shaped container are folded by bringing down the side walls, the partition member can be folded and assembled without taking out the partition member from the folded container assembled into a box shape. A box-shaped foldable container.

Since the folded side panels of the partition member arranged in the foldable container assembled into a box shape are located on the side wall side which is first laid down from the state assembled into a box shape, it is not necessary to take out the partition member from the foldable container assembled into a box shape. A collapsible container that can be folded and assembled into a box shape.

In order to prevent the side wall that fell first from the state assembled into a box shape from contacting the folded partition member, the blocking rib that the side wall that fell first came into contact protrudes from the side that fell after being hinged. Therefore, when the folding operation of a box-shaped foldable container is performed, it is possible to prevent the partition member from colliding with the side wall that fell first, thereby preventing the partition member or the side wall that fell first from being damaged. damage.
