2. Description of the Related Art Conventionally, as shown in FIG. 7, a rectangular bottom plate 2, an upper frame 3 arranged above the bottom plate 2, and a long side between the bottom plate 2 and the upper frame 3 are arranged. A pair of long side plates 4 and a pair of short side plates 7 arranged on the short side between the bottom plate 2 and the upper frame 3
The upper end 7a of the short side plate 7 is rotatably connected to the upper frame 3 so that the short side plate 7 can be turned upside down, and the long side plate 4 is made up of the upper half upper plate 5 and the lower half lower long plate. 6, the upper end 5 a of the upper long side plate 5 is rotatably connected to the upper frame 3, the lower end 6 b of the lower long side plate 6 is rotatably connected to the bottom plate 2, and the lower end of the upper long side plate 5. There is known a folding container 1 in which a top 5b and an upper end 6a are rotatably connected. When transporting a fragile storage item A such as a bottle, the mounting plate 12 of the partition member 10 for partitioning the storage space 11 of the container 1 is attached to the container 1 in order to protect the storage item A from vibration, impact, and the like. It is mounted so as not to move on the inner wall surface of the device, and the storage items a are stored in the partition space 11a partitioned by the partition member 10.

[0003]

As a method of mounting the partition member 10, conventionally, the mounting plate 12 is integrally fixed to the inner wall surface of the short side plate 7 by bonding or welding. When the member 10 is unnecessary, there is a problem that it cannot be removed and the folding container 1 cannot be folded.

Therefore, as another conventional example, a method of removably fixing the mounting plate 12 using bolts has been attempted. In this case, the mounting of the mounting plate 12 is very troublesome, and the mounting plate 12 has to be removed. This is also very troublesome, and the tips of the bolts may protrude inside the mounting plate 12 while the partition member 10 is in use, possibly damaging the stored items a.

As still another conventional example, Japanese Utility Model Publication No. 4-532
No. 6 discloses a method of detachably attaching a partition member to an inner surface of a container using a magic tape (registered trademark). In this case, attachment and detachment are easier than bolts. In addition, since a separate part of the magic tape is required from the partition member, the number of parts is increased and the cost is high. In addition, when the partition member is removed, one of the magic tapes (either the female side or the male side) is used. Remains on the inner wall surface of the container, and there is a problem that dirt adheres to the inner wall surface, the inner wall surface cannot be smoothed, the appearance is impaired, and storage is hindered.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art. It is an object of the present invention to easily attach and detach a partition member, to reduce the number of parts and to reduce cost. It is another object of the present invention to provide a folding container which can sufficiently protect stored items while the partition member is in use, and which can secure good appearance and smoothness of the inner wall surface of the container when the partition member is removed.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments shown in the accompanying drawings.

As shown in FIG. 2, the folding container 1 of this embodiment has a rectangular bottom plate 2, an upper frame 3 disposed above the bottom plate 2, and a long side between the bottom plate 2 and the upper frame 3. And a pair of short side plates 7 disposed on the short side between the bottom plate 2 and the upper frame 3, and the upper end 7 a of the short side plate 7 is rotated to the upper frame 3. It can be freely connected to make the short side plate 7 up and down,
The long side plate 4 comprises an upper half upper plate 5 and a lower half lower plate 6, and the upper end 5a of the upper side plate 5 is rotatably connected to the upper frame 3 and the lower end of the lower long plate 6 6b is rotatably connected to the bottom plate 2, and the lower end 5b and the upper end 6a of the upper long side plate 5 are rotatably connected to form the folding container 1. Up to this point, the folding container 1 is the same as the conventional folding container. is there.

In the present invention, in order to detachably attach the partition member 10, two notches 8 on the left and right are formed at the center side of the short side plate 7 of the folding container 1 at predetermined intervals in the lateral direction. The two right and left notches 8 form two right and left fitting convex pieces 9 facing each other. In the example of FIG. 2, a pair of notches 8 are formed in U-shape in opposite directions, and the inside of each notch 8 is a fitting convex piece 9, and the fitting convex piece 9 is formed.
Direction A in which the distal end 9b side is opposed to the base end 9a side
It protrudes in a convex shape toward. Further, as shown in FIG. 1, the inner surface 9d of each of the fitting convex pieces 9 is formed substantially flush with the inner wall surface 7b of the short side plate 7, and when the partition member 10 is removed, the short side plate 7 No irregularities are formed on the inner wall surface 7b.

As shown in FIG. 3, the partition member 10 includes two vertical partition plates 15 for partitioning the storage space 11 in the longitudinal direction and two foldable horizontal partition plates for partitioning the storage space 11 in the short direction. 16 and one mounting plate 12 are combined in a lattice shape when viewed from a plane, and the inside of each is a partition space 11a. Here, one end 18 of each of the two horizontal partition plates 16 is rotatably connected to both left and right ends of the mounting plate 12, and each other end 19 has a vertical partition plate 15 remote from the mounting plate 12. Is rotatably connected to the Here, both ends 18, 19 of the horizontal partition plate 16
A first outer bent portion 20, an inner bent portion 17, and a second outer bent portion 21 are provided between the inner bent portions 17.
The vertical partition plate 15 closer to the mounting plate 12 is held along. Then, by folding the horizontal partition plate 16 in the direction shown by (b) in FIG. 4A, the two vertical partition plates 15 are drawn toward the mounting plate 12, and the entire partition member 10 becomes flat. By extending the horizontal partition plate 16 in the direction indicated by c in (b), the two vertical partition plates 15 are separated from the mounting plate 12 so as to be in a usable state of a vertical and horizontal lattice. .

Here, the mounting plate 12 is shown in FIG.
As shown in FIG. 5, the flexible partition member is formed of a flexible material, such as thick paper or soft plastic, which can be bent in a substantially C shape by hand so as to be convex toward the vertical partition plate 15 side. . Of course, the material of the mounting plate 12 is not limited to these.

At the left and right ends of the mounting plate 12, vertically long slits 14 are respectively formed.
2 inside the slit 14 (FIG. 4A)
) Are hooking and locking pieces 13 respectively. Here, the horizontal width D (FIG. 3) of the mounting plate 12 is such that when the horizontal partition plate 16 is extended, the two horizontal partition plates 16
Are set to be parallel to each other. The distance d between the tips 9b, 9b of the two hooking locking pieces 13 is longer than the shortest distance L1 between the tips 9b of the pair of right and left fitting projections 9 provided on the short side plate 7, and the fitting is performed. It is set shorter than the maximum distance L2 between the base ends 9a of the convex pieces 9. When the mounting plate 12 is bent so as to protrude toward the vertical partition plate 15, the distance d between the tips 9 b of the hooking locking pieces 13 is the shortest distance between the tips 9 b, 9 b of the fitting projection 9. L1 is substantially the same as or shorter than L1.
b can be fitted, whereby the hooking locking piece 13 can be hooked and locked on the outer surface 9c of the convex piece 9, and the partition member 10 integrated with the mounting plate 12 can be fitted to the short side plate 7. It can be detachably attached to the inner wall surface 7b.

That is, when the partition member 10 is mounted on the short side plate 7, the mounting plate 12 is first bent by hand into a substantially C-shape so as to project toward the vertical partition plate 15 (FIG. 1A). State), the ends of the two left and right hooking and locking pieces 13 of the mounting plate 12 are passed through the two left and right notches 8 of the short side plate 7, and then the mounting plate 12 bent in a substantially C shape is shortened. By pushing the mounting plate 12 back to the original flat state by pushing the mounting plate 12 to the side plate 7,
Is fitted and latched while sliding on the outer surface 9c of the convex piece 9 (the state shown in FIG. 1B), and the mounting plate 12 is easily and reliably mounted on the inner wall surface 7b of the short side plate 7. As a result, the partition member 10 integrated with the mounting plate 12 can be easily mounted on the short side plate 7.

When removing the partition member 10,
By bending the mounting plate 12 into a substantially C-shape as shown in FIG. 1 (a), the hooking locking piece 13 can be fitted and removed from the convex piece 9, and as a result, the mounting plate 12 can be easily removed from the short side plate 7. Can be removed.

As described above, by adopting the system in which the hooking and locking piece 13 is fitted and hooked on the outer surface 9c of the convex piece 9, the mounting and dismounting of the partition member 10 becomes easy, and the conventional bolt or magic tape is used. Unlike the fixing method according to the first embodiment, no member separate from the partition member 10 is required at all, the cost can be reduced, and the attachment and detachment can be easily performed manually, thereby improving the usability. In addition, since the stored article A is not damaged by the bolts during use of the partition member 10, the stored article A can be stored while being sufficiently protected. In addition, since the mounting plate 12 is detached integrally with the partition member 10, no magic tape or the like as in the related art remains on the inner wall surface of the container 1, so that the inner wall surface of the container 1 does not adhere with dirt due to the magic tape. Furthermore, the inner surface 9d of the fitting convex piece 9
Is formed substantially flush with the inner wall surface 7b of the short side plate 7, so that after the mounting plate 12 is removed, no irregularities are formed on the inner surface 9d of the short side plate 7, and as in the case of a normal folding container, Good appearance and smoothness of the inner wall surface of the container 1 can be simultaneously secured.

Further, since the hooking and retaining piece 13 is formed by providing the slit 14 in the mounting plate 12, the formation of the hooking and retaining piece 13 is easy.
Can be used also as the hooking and locking piece 13, so that the number of parts does not increase and the mounting plate 12 can be mounted so as not to protrude outside and inside the short side plate 7, respectively. In addition to certainty, good appearance can be obtained at the same time. That is, since the two fitting projections 9 are formed so that the tip 9b side protrudes in the direction A opposite to the base end 9a side in the direction A facing each other, unless the attachment plate 12 is intentionally bent, the pull-in is performed. The latching piece 13 does not come off the fitting projection 9 and can be securely attached. Moreover, the hook locking piece 1
3 is engaged with the outer surface 9 c of the convex piece 9,
The portion of the mounting plate 12 other than the hooking and locking pieces 13 is in surface contact with the inner wall surface 7b of the short side plate 7 including the inner surface 9d of the fitting projection 9, so that the mounting plate 12 adheres to the inner wall surface 7b of the short side plate 7. And the outer surface 9 of the fitting convex piece 9
Since the adhesion of the hooking locking pieces 13 to c is obtained, the positioning effect of the partition member 10 is obtained by the mounting plate 12, and the mounting can be performed more reliably.

In the present embodiment, the hooking locking pieces 13 provided on both right and left ends of the mounting plate 12 are fitted into the two fitting convex pieces 9 facing left and right, but the invention is not necessarily limited to this. Instead, for example, as shown in FIG. 5 (a), two fitting protrusions 9 which are vertically opposed may be provided. In this case, both upper and lower ends of the mounting plate 12 may be used as hooking and locking pieces. Further, the numbers of the fitting protrusions 9 and the hooking locking pieces 13 can be appropriately changed. For example, as shown in FIG.
As a set, a plurality of sets of fitting protrusions 9 are formed on the short side plate 7 vertically, and the same number of hooking locking pieces 13 as the fitting protrusions 9 are formed.
May be provided on the mounting plate 12.
Alternatively, as shown in FIG. 5C, a plurality of sets of fitting convex pieces 9 may be formed on the left and right. In each case, the number of places where the mounting plate 12 is locked to the short side plate 7 increases. Thus, the mounting strength of the partition member 10 can be further increased.

The shape of the notch 8 for forming the fitting convex piece 9 is not necessarily limited to a U-shape, and may be, for example, a semicircular arc shape shown in FIG. 6A or a horizontal V shape shown in FIG.
The shape may be a horizontal W-shape or the like as shown in FIG. 6 (c). The point is that the distal end 9 b side of the fitting convex piece 9 protrudes in the direction A which is opposite to the base end 9 a side. It just needs to be.

In the above-described embodiment, the case where the partition member 10 is detachably attached to only one of the short side plates 7 has been described. However, it is needless to say that the convex pieces 9 fitted by the notches 8 are provided on both the short side plates 7. It is also possible to detachably attach the two partition members 10 to the respective short side plates 7. In this case, by increasing the number of the partition members 10, it becomes easy to partition the entire storage space 11 of the container 1 substantially uniformly. Of course, the entire storage space 11 may be substantially evenly partitioned by one partition member 10.

A pair of hooking locking pieces are provided on the outer surfaces of the pair of fitting protrusions through the cutouts, respectively. The pair of hooking locking pieces are respectively provided on the outer surfaces of the pair of fitting protrusions. By hooking and locking,
Since the partition member is removably mounted on the inner wall surface of the short side plate via the mounting plate, the hooking locking piece provided on the mounting plate is cut out of the short side plate by bending the flexible mounting plate. Can be easily hooked onto the fitting convex piece, and then can be securely attached to the inner wall surface of the short side plate by extending the mounting plate, and the pair of fitting convex pieces is more than the base end side. Since the tips are formed so as to protrude in the convex direction in the opposite direction, unless the mounting plate is intentionally bent, the hooking locking piece does not come off from the convex piece and can be securely attached. it can. Moreover, since the hooking locking piece can be fitted and removed from the convex piece by bending the mounting plate, the partition member can be easily removed. Therefore, there is no problem that the folding container cannot be folded unlike the conventional fixing method by bonding or welding, and unlike other conventional fixing methods using bolts, fasteners, and the like, other members are attached. Not required at all, costs can be reduced, partitioning members can be easily attached and detached by hand, improving usability, and during use of partitioning members, bolts may damage stored items like conventional bolts Therefore, the storage can be stored while sufficiently protecting the storage items. Since the mounting plate is also removed after the partition member is removed, the appearance of the inner wall surface of the container can be improved.
