In addition, when folding, the long side walls and the short side wall.

In the above-mentioned conventional foldable container, there is a problem that the strength and rigidity of the long side wall are weak and easy to deform. Especially with the increase in size of the foldable container, when the lateral width of the long side wall exceeds 1 m or approaches 2 m, the deformation of the long side wall is significant, and it is difficult to hold and transport the long side wall assembled in a box shape.

When transporting and assembling into a box-shaped foldable container, usually the operator grasps the holding portion formed in the central upper part of the opposite short side wall with both hands on one side of the long side wall to transport and assemble into a box-shaped foldable container. The lateral width of the side wall is relatively short, so the short side wall will not fall or bend inwardly, so the articles contained in the foldable container will not be damaged. However, when the lateral width of the long side wall exceeds 1 m or is close to 2 m, it is difficult to hold the gripping portion formed on the central upper part of the opposite short side wall to transport the folded container assembled into a box shape, and usually the operator is located on one side of the long side wall. Afterwards, the folded container assembled into a box shape is carried by holding appropriate holding portions of respectively opposite long side walls with both hands. When carrying the folded container assembled into a box shape by grasping the holding parts formed on the opposite long side walls in this way, the long side walls are tilted inward or are bent greatly, so that the articles accommodated in the foldable container are damaged, or the long side walls are damaged. damage.

After falling down, the long side walls 2 are overlapped to the short side walls 3 of the bottom 1, so that as shown in FIG. 3 , the collapsible container is folded into a compact state with a low height. In addition, from the folded state shown in FIG. 3, the long side wall 2 is erected approximately vertically, and then the short side wall 3 is erected approximately vertically, so that the folded container can be assembled into a box as shown in FIG. 1 . shape.

The long side wall 2 has a horizontally long substantially rectangular plate-shaped portion 2a, and a vertically long joint frame that is substantially perpendicular to the plate-shaped portion 2a and extends toward the inner wall surface of the long side wall 2 is formed at two vertical ends of the long side wall 2 2b, an appropriate number of fitting holes 2b1 (two fitting holes 2b1 are formed in this example) substantially parallel to the plate-like portion 2a are formed on the joining frame 2b at predetermined intervals in the vertical direction.

Near both ends of the upper portion of the plate-shaped portion 2a of the long side wall 2 are respectively formed with substantially U-shaped slits 2c. A cantilever-shaped engagement elastic piece 2d extending in the direction. Engagement protrusions 2d1 protrude from the inner front end of the engagement elastic piece 2d, and the engagement frame 2b side of the engagement protrusions 2d1 forms a vertical surface substantially parallel to the inner surface of the engagement frame 2b.

At the upper and lower ends of the plate-shaped portion 2a of the long side wall 2, an upper end horizontal rib 2e and a lower end horizontal rib 2f that are substantially perpendicular to the plate-shaped portion 2a and extending outward are formed. When assembled into a box shape, an appropriate number of vertical ribs 2g and horizontal ribs 2h are formed on the outer side).

The short side wall 3 has a horizontally long substantially rectangular plate-like portion 3a, and an upper end horizontal rib 3b and a lower end horizontal rib 3c that are substantially perpendicular to the plate-like portion 3a and extend outward are respectively formed at the upper and lower ends of the plate-like portion 3a. End vertical ribs 3 d that are substantially perpendicular to the plate-shaped portion 3 a and extend to the outside are respectively formed at left and right ends of the plate-shaped portion 3 a. A vertically elongated extension frame 3e is formed on the outside of the end vertical rib 3d, and an appropriate number of matching protrusions 3e1 are formed along the end vertical rib 3d on the extension frame 3e (in this embodiment, corresponding to the above-mentioned joint frame formed on the extension frame 3e). Two fitting holes 2b1 of 2b form two fitting protrusions 3e1). The fitting convex part 3e1 can be inserted into the fitting hole 2b1 formed in the joining frame 2b of the said long side wall 2. As shown in FIG. In addition, an appropriate number of vertical ribs 3f and horizontal ribs 3g are formed on the outer surface of the plate-like portion 3a (the outer surface when the foldable container is assembled into a box shape).

When assembling the foldable container into the box shape shown in FIG. 1 from the folded state shown in FIG. 3 , the long side walls 2 in the substantially horizontal state are turned vertically and stand up substantially vertically as shown in FIG. 2 . Then, the short side wall 3 folded so as to overlap with the bottom 1 is turned from the substantially horizontal state to the vertical direction, and the extension frame 3 e of the short side wall 3 is brought close to the joining frame 2 b formed on the long side wall 2 . When the short side wall 3 is rotated towards the vertical direction, the end vertical surface of the extension frame 3e of the short side wall 3 pushes the engaging protrusion 2d1 of the engaging elastic piece 2d protruding from the inner surface of the long side wall 2 toward the outer direction. The engaging elastic piece 2d is bent against the elasticity of the engaging elastic piece 2d. In addition, when the short side wall 3 is turned vertically, the fitting protrusion 3e1 of the extension frame 3e protruding from the short side wall 3 is inserted into the fitting hole 2b1 formed in the joining frame 2b of the long side wall 2 . In the process of inserting the fitting protrusion 3e1 of the extension frame 3e protruding from the short side wall 3 into the fitting hole 2b1 formed in the joining frame 2b of the long side wall 2, the joint elastic piece 2d formed on the long side wall 2 The engaging convex part 2d1 is disengaged from the end vertical surface of the extension frame 3e of the short side wall 3, and the engaging elastic piece 2d returns to its original position by its elasticity, and the engaging convex part 2d1 of the engaging elastic piece 2d contacts or approaches the short side wall 3 extension box 3e. Therefore, even if the short side wall 3 is going to turn toward the bottom 1, the extension frame 3e of the short side wall 3 also contacts the engaging convex portion 2d1 of the engaging elastic piece 2d formed on the long side wall 2, preventing the turning toward the bottom 1. Even if a load is applied to the short side wall 3 from the outside, it will not fall down toward the bottom 1 . Similarly, the other short side wall 3 is turned from the substantially horizontal direction to the vertical direction to assemble the foldable container into a box shape.

When the folded container assembled into a box shape is folded, the joint elastic piece 2d of the long side wall 2 is pushed outward against its elasticity to be bent, and the joint elastic piece 2d of the joint elastic piece 2d is raised from the extension frame 3e of the short side wall 3. Part 2d1 is disengaged. When the engaging protrusion 2d1 of the engaging elastic piece 2d formed on the long side wall 2 is released from the extension frame 3e of the short side wall 3, the short side wall 3 is turned toward the bottom 1, and a pair of opposing short side walls 3 Coincident onto bottom 1. Then, a pair of opposite long side walls 2 are superimposed on a pair of opposite short side walls 3 superimposed on the bottom 1, so that the folded container assembled into a box shape can be folded.

The lower horizontal rib s1d of the operating part s1 is connected with a vertical rod s2 made of a rod, a plate, or a profile, and at the same time, on the opposite surfaces of the lower end of the vertical rod s2, elastic tongues inclined downward are respectively connected. slice s3. In addition, a wedge-shaped insertion member s4 with a sharp front end is formed at the lower end of the vertical rod portion s2. The fall prevention member S1 composed of the operation portion s1, the vertical rod portion s2, the elastic tongue piece s3, and the insertion member s4 is preferably integrally formed of synthetic resin.

A pair of vertical ribs connecting the upper end horizontal rib 2e and the lower end horizontal rib 2f are formed at a predetermined interval at the central portion of the outer surface of the plate-like portion 2a of the long side wall 2 (the outer surface when the foldable container is assembled into a box shape). Guide rib 2i. In addition, on the opposite surface of the vertical guide rib 2i, a restricting protrusion 2j is protruded. In addition, the vertical guide rib 2i is connected below the vertical guide rib 2i. 2k. In addition, the upper end of the horizontal connecting rib 2k is connected to the back surface of the horizontal connecting rib 2k by sandwiching the through hole 2k1 formed in the horizontal connecting rib 2k, and at the same time, a pair of inclined guide plate portions 2m extending in directions away from each other are formed as they go downward. , the lower end of the inclined guide plate portion 2m is connected to the vertical guide rib 2i by the horizontal connecting rib 2n.

A through hole 2f1 having substantially the same size and shape as the through hole 2k1 is drilled in the lower end horizontal rib 2f of the long side wall 2 directly below the through hole 2k1 of the above-mentioned horizontal connecting rib 2k. In addition, when the foldable container is assembled into In the case of a box shape, the horizontal portion 1a1 of the long side bank 1a of the bottom 1 directly below the through hole 2k1 of the horizontal connecting rib 2k and the through hole 2f1 of the lower end horizontal rib 2f of the long side wall 2 The through-hole 1a2 through which the insertion member s4 of the above-mentioned fall prevention member S1 can be inserted is formed.

A part of the sliding protrusion protruding from the vertical rib s1b constituting the operation portion s1 of the fall restraining member S1 is defined by the restriction projection 2j protruding from the opposite surface of the vertical guide rib 2i formed on the long side wall 2 and the long side wall. 2, the plate-shaped part 2a of 2 is sandwiched, and the vertical rod s2 of the falling restraining member S1 is inserted into the through hole 2k1 pierced through the horizontal connecting rib 2k, and the pair of elastic tongues s3 of the falling restraining member S1 contacts or approaches the inclined guide The fall prevention member S1 is disposed between a pair of vertical guide ribs 2i formed on the long side wall 2 so as to form a plate portion 2m. When the foldable container is assembled into a box shape, as shown in FIG. 5 and FIG. The through hole 1a2 of the horizontal portion 1a1 of the long side bank portion 1a also forms a pair of elastic tongue pieces s3 of the fall prevention member S1 in contact with or close to the inclined guide plate portion 2m. Therefore, even if a load is applied from the outside to the inside on the long side walls 2 of the foldable container assembled into a box shape, the long side walls 2 can be suppressed from falling or bending inward. When the gripping part of the appropriate position (for example, constituted as an opening formed by the plate-shaped part 2a near the upper end horizontal rib 2e of the long side wall 2) and the upper end horizontal rib 2e are transported and assembled into a box-shaped foldable container, the long side wall 2 It does not fall or bend inward to a large extent, and it is possible to prevent damage to articles accommodated in the foldable container or damage to the long side wall 2 .

In addition, when performing the folding operation of the foldable container assembled into a box shape, in order to make the long side wall 2 standing upright as shown in FIG. The back surface of the upper horizontal rib s1a of the portion s1 moves the fall prevention member S1 upward. When the fall suppression member S1 is moved upward, the sliding protrusion s1b' protruding from the vertical rib s1b constituting the operation portion s1 of the fall suppression member S1 is formed on the opposite surface of the vertical guide rib 2i formed on the long side wall 2. The restriction protrusion 2j and the plate-like portion 2a of the long side wall 2 hold the guide, so that the fall prevention member S1 can be smoothly moved upward without the fall prevention member S1 coming off from the long side wall 2 . As shown in FIG. 7 , the pair of elastic tongue pieces s3 of the fall prevention member S1 is brought into contact with the inclined guide plate portion 2m by the upward movement of the fall prevention member S1, and the front ends of the pair of elastic tongue pieces s3 are directed toward the approaching direction. Elastic deformation is carried out, and at the same time, as shown in FIGS. The through hole 2f1 of the lower end horizontal rib 2f of the long side wall 2 is discharged. In this state, the long side wall 2 is tilted toward the bottom 1, so that the foldable container can be folded as shown in FIG. 3 . After the long side wall 2 falls toward the bottom 1, the hand is separated from the operation portion s1 of the fall restraining member S1, and the fall restraining member S1 is moved toward the falling restraint member S1 by the restoring force caused by the elastic deformation of the above-mentioned elastic tongue piece s3 of the fall restraint member S1. Move down and return to the original position as shown in Figure 5.

When assembling the foldable container into a box shape, as described above, the long side wall 2 is turned in the vertical direction, and when the long side wall 2 is turned, hang your finger or the like on the upper level of the operation part s1 forming the fall prevention member S1. On the back side of the rib s1a, the tipping restraining member S1 is moved upward so that the front end of the insertion member s4 of the tipping restraining member S1 is located in the through hole 2f1 of the lower end horizontal rib 2f of the long side wall 2, or is discharged from the through hole 2f1. . After the long side wall 2 is erected substantially vertically, let go of the operation portion s1 of the fall prevention member S1, and the fall prevention member S1 moves downward by the restoring force generated by the elastic deformation of the above-mentioned elastic tongue piece s3 of the fall prevention member S1. The insertion member s4 of the fall prevention member S1 is inserted into the through hole 2f1 of the lower end horizontal rib 2f of the long side wall 2 and the through hole 1a2 of the horizontal portion 1a1 of the long side bank 1a of the bottom 1 . In this case, instead of forming the insertion member s4 into a wedge shape, it may be formed into a block shape such as a rectangle or a column.

In the front surface of the insertion member s4 of the fall prevention member S1 of the present embodiment, an inclined surface s4a is formed from the upper end surface of the insertion member s4 (the surface on the lower end side of the vertical rod portion S2) toward the front end toward the long side wall. The outer surface of the plate-shaped part 2a of 2 (the surface located on the outside when the foldable container is assembled into a box shape) is inclined, so the rotation process of the long side wall 2 in the vertical direction during the operation of assembling the foldable container into a box shape Among them, the inclined surface s4a formed in front of the insertion member s4 of the fall prevention member S1 is in contact with the upper inner corner 1a3 of the long side bank 1a of the bottom 1, resisting the elastic force of the elastic tongue piece s3 of the fall prevention member S1, so that The fall suppressing member S1 moves upward. Thereafter, when assembled substantially vertically, the long side wall 2 is moved downward by the restoring force generated by the elastic deformation of the elastic tongue s3 of the fall restraining member S1, and the insertion member s4 of the fall restraint member S1 is inserted and penetrated. The through hole 2f1 of the horizontal rib 2f at the lower end of the long side wall 2 and the through hole 1a2 of the horizontal portion 1a1 of the long side bank 1a of the bottom 1 are pierced. In this way, by forming the inclined surface s4a capable of contacting the long side bank 1a of the bottom 1 on the insertion member s4 of the fall prevention member S1, fingers and the like can be caught on the upper horizontal rib s1a forming the operation part s1 of the fall prevention member S1. There is no need to move the tipping restraining member S1 upwards, and the insertion member s4 of the tipping restraining member S1 can be inserted into the horizontal rib at the lower end of the long side wall 2 just by rotating the long side wall 2 in the vertical direction. The through-hole 2f1 of 2f and the through-hole 1a2 penetrated in the horizontal part 1a1 of the long-side bank part 1a of the bottom part 1 are formed.

As described above, when the foldable container is to be assembled into a box shape, the insertion member s4 of the fall prevention member S1 disposed on the long side wall 2 is inserted into the through hole 2f1 and the through hole 2f1 of the lower end horizontal rib 2f penetrating the long side wall 2 . Since the through-hole 1a2 provided in the horizontal portion 1a1 of the long side bank 1a of the bottom 1 is configured, even if a load is applied to the long side wall 2 from the outside to the inside, the long side wall 2 can be prevented from falling or bending inward. Therefore, when the folded container assembled into a box shape is transported by holding the gripping portion or the upper end horizontal rib 2e formed on an appropriate portion of the opposite long side wall 2, the long side wall 2 will not fall or bend inwardly, preventing storage Item damage or long side wall 2 damage in collapsible containers.

In particular, by inserting the insertion member s4 of the fall prevention member S1 into the through hole 2f1 of the lower end horizontal rib 2f of the long side wall 2 and the through hole 1a2 of the horizontal portion 1a1 of the long side bank 1a of the bottom 1, , so that when a load is applied to the long side wall 2 of the folded container assembled into a box shape from the outside toward the inside, the long side is blocked between the lower end horizontal rib 2f of the long side wall 2 and the long side bank 1a of the bottom 1. The lower end horizontal rib 2f of the wall 2 is separated from the long-side bank portion 1a, so that the long-side wall 2 can be more reliably and effectively suppressed from falling and bending inwardly.

Next, another embodiment of the present invention will be described with reference to FIGS. 9 to 13. Its basic configuration is the same as that of the above-mentioned embodiment. Therefore, detailed descriptions of the same components will be omitted, and the same symbols will be used.

The fall prevention member S2 of this embodiment has the same operation portion s1 as that of the fall prevention member S1 of the above embodiment, and the member s20 is vertically inserted into the inclined rib s1c and/or the lower horizontal rib s1d of the operation portion s1. In this embodiment, the insertion member s20 is constituted by, for example, three elongated plates s20a arranged in parallel to each other and a connection plate s20b connecting one end of the elongated plates s20a. The insertion member s20 may also be composed of square pillars, cylinders, square cylinders, cylinders and other cylinders. In addition, a restricting projection 2j is protruded on the opposite surface of the vertical guide rib 2i formed on the long side wall 2, and a lower restricting projection 20j having the same function as the restricting projection 2j is formed below the restricting projection 2j. In this embodiment, the horizontal connecting ribs 2k through which the through holes 2k1 are pierced are omitted.

The through-hole 2f1 of the lower end horizontal rib 2f of the long side wall 2 and the through-hole 1a2 of the horizontal portion 1a1 of the long-side bank 1a of the bottom 1 form substantially the same size and shape, and can be inserted into the above-mentioned pouring The insertion member s20 of the suppression member S2 is comprised. In this embodiment, the horizontal connection rib 2k with the through hole 2k1 can also be formed. In this case, the size and shape of the through hole 2k1 through the horizontal connection rib 2k is at the level The through hole 2f1 of the rib 2f has substantially the same configuration as the through hole 1a2 penetrating the horizontal portion 1a1 of the long-side bank portion 1a of the bottom 1 .

In this embodiment, the elastic tongue piece s3 of the fall prevention member S1 of the above-mentioned embodiment is not disposed, so the vertical movement of the fall prevention member S2 is all performed by hand.

When the foldable container is assembled into a box shape, as shown in FIG. 10 and FIG. The through hole 1a2 of the horizontal portion 1a1 of the long side bank 1a of the bottom 1 and about half or more of the insertion member s20 are located in the long side bank 1a of the bottom 1 . In this embodiment, the insertion member s20 of the fall prevention member S2 is configured so as to be located inside the long-side bank 1a formed by the horizontal portion 1a1, the inner wall 1a4, and the outer wall 1a5, and has a cross-section perpendicular to its longitudinal direction. The shape is generally formed in an inverted U-shape.

In this embodiment, when the foldable container is assembled into a box shape, the insertion member s20 of the fall prevention member S2 is fitted into the through hole 2f1 of the lower end horizontal rib 2f of the long side wall 2 and the bottom 1 of the bottom 1. The through-hole 1a2 of the horizontal portion 1a1 of the long-side bank 1a is formed so that about half or more of the insertion member s20 is located in the long-side bank 1a of the bottom 1, so it is different from that of only the toppling restraining member S1. The insertion member s4 is fitted to the toppling restraining member of the above-mentioned embodiment in which the through hole 2f1 passed through the lower end horizontal rib 2f of the long side wall 2 and the through hole 1a2 passed through the horizontal portion 1a1 of the long side bank 1a of the bottom 1 Compared with S1, when a load is applied to the long side wall 2 of the folded container assembled into a box shape from the outside toward the inside, the long side wall 2 can be more reliably and effectively suppressed from falling or bending toward the inside.

In addition, when the folding operation of the foldable container assembled into a box shape is performed, the fall prevention member S2 moves upward, and passes through the through hole 1a2 of the horizontal portion 1a1 of the long side bank 1a of the bottom 1 and the horizontal portion 1a1 of the long side bank 1a. The through hole 2f1 of the lower end horizontal rib 2f of the side wall 2 discharges the insertion member s20 of the fall restraining member S2. In this state, the foldable container assembled in a box shape can be folded by falling the long side walls 2 toward the bottom 1 .

On the connecting plate s20b of the insertion member s20 constituting the fall prevention member S2, an engaging protrusion s20c extending in the direction of the plate-shaped portion 2a of the long side wall 2 is protruded, and at the same time, the plate-shaped portion 2a of the long side wall 2 is spaced vertically. Recesses or through-holes into which the engagement protrusions s20c can fit are formed at predetermined intervals. The upper recess or through-hole is called the upper joint pudendum, and the symbol 2p1 is used, and the lower recess or through-hole is called the lower joint pudendum, and the symbol 2p2 is used.

When the fall prevention member S2 is moved upward, the insertion member s20 of the fall prevention member S2 is at the level from the through hole 2f1 of the lower end horizontal rib 2f of the long side wall 2 and the long side bank 1a of the bottom 1. When the through hole 1a2 of the part 1a1 is discharged, as shown in FIG. , Even if you let go, the fall suppression member S2 is constructed so that it does not naturally move downward. With such a configuration, the insertion member s20 of the fall prevention member S2 does not go over the lower end horizontal rib 2f of the long side wall 2 and is positioned below. Therefore, when the foldable container in the folded state is assembled, it is prevented from going over the lower end horizontal rib of the long side wall 2. 2f The insertion member s20 of the lower fall prevention member S2 contacts the long side bank 1a of the bottom 1, hinders the vertical rotation of the long side wall 2, and forms an obstacle to the operation of assembling the folded container into a box shape, or prevents it from falling over. Damage to the member S2 and the long-side bank 1 a of the bottom 1 is suppressed.

In addition, the fall prevention member S2 is moved downward, and the insertion member s20 of the fall prevention member S2 is inserted into the through hole 2f1 of the lower end horizontal rib 2f of the long side wall 2 and the long side bank of the bottom 1.

With such a configuration, it is possible to prevent the insertion member s20 of the fall prevention member S2 from unintentionally slipping from the through hole 2f1 of the lower end horizontal rib 2f of the long side wall 2 and the horizontal portion of the long side bank 1a of the bottom 1. The through hole 1a2 of 1a1 discharges, so when a load is applied to the long sidewall 2 of the folded container assembled into a box shape from the outside toward the inside, the long sidewall 2 can be prevented from toppling and bending toward the inside.

When the foldable container is assembled into a box shape, a stopper s20d such as a step is formed on the connecting plate s20b constituting the fall restraining member S2 near the horizontal portion 1a1 of the long-side embankment 1a of the bottom 1, as shown in FIG. 11 Thus, placing the stopper s20d on the horizontal portion 1a1 of the long-side bank 1a prevents unnecessary insertion of the insertion member s20 of the fall prevention member S2 into the long-side bank 1a.

In particular, by inserting the insertion member s20 of the fall prevention member S2 into the through hole 2f1 of the lower end horizontal rib 2f of the long side wall 2 and the through hole of the horizontal portion 1a1 of the long side bank 1a of the bottom 1, 1a2, so that when a load is applied to the long side wall 2 of the folded container assembled into a box shape from the outside toward the inside, the long side wall 2f between the lower end horizontal rib 2f of the long side wall 2 and the long side bank 1a of the bottom 1 is blocked. The lower end horizontal rib 2f of the side wall 2 is separated from the long side bank portion 1a, so that the long side wall 2 can be more reliably and effectively suppressed from falling and bending inwardly.

Next, another embodiment of the present invention will be described with reference to FIGS. 14 to 15, and the detailed description will be omitted for the same constituent members as those of the above-mentioned embodiment, and the same symbols will be used.

The fall restraining member S3 of this embodiment has a horizontal rotary lever s30, and a clamping portion s31 installed on the front end of the horizontal rotary lever s30 and having a cross-sectional shape perpendicular to the longitudinal direction and substantially U-shaped. The sandwiching portion s31 is formed by an upper horizontal portion s31a, a lower horizontal portion s31b parallel to the upper horizontal portion s31a, and a vertical portion s31c connecting one edge of the upper horizontal portion s31a and the lower horizontal portion s31b. The fall prevention member S3 is rotatably pivoted to the lower horizontal rib 2f of the long side wall 2 by attaching the end of the horizontal rotary lever s30 to the approximate center of the lower horizontal rib 2f of the long side wall 2 via the short axis s32. In addition, a slot 1a6 into which the lower horizontal portion s31b of the holding portion s31 can be inserted is formed in the outer wall 1a5 of the long-side bank portion 1a constituting the bottom 1 .
