A foldable container 10 according to this embodiment is used, for example, for the trucking of precision electronic components such as substrates used in the manufacture of electrical products. These parts are organized and stored in the compartments within the bellows partition 16. Although the box main body 12 in the state which the bellows partition part 16 does not enter is shown in FIG. 1, the bellows partition part 16 can be made into the expanded state at the time of use (refer FIG. 3 (a)). On the other hand, when not in use, the bellows partition can be folded and the container body can be folded and stored (see FIG. 4).

Therefore, first, the configuration of the box body 12 will be described.
In FIG. 1, the X direction is the longitudinal direction of the box body 12, the Y direction is the height direction of the box body 12, and the Z direction is the width direction of the box body 12.

  The box body 12 has a bottomed box shape from the lower frame 15 having the bottom plate 13, the upper frame 11 forming the opening of the box, the longitudinal side faces 14 and the lateral faces 17 and 17 in the width direction It is configured. Each part of such a box main body 12 is made of plastic, and a plastic corrugated board having a corrugated board structure is used. By this, the weight reduction of the box body is achieved.

  Along the upper edge of the longitudinal side 14, a fold line 18 extending in the X direction is formed. The fold line 18 is formed by half-cutting the surface of the plastic corrugated board and can be easily folded along the fold line 18. Similarly, a fold line 19 parallel to the fold line 18 is formed at the center of the longitudinal side 14. In addition, a fold line 25 extending in the X direction is also formed at the lower edge of the side surface 14 in the longitudinal direction.

Next, on the side surface 17 in the width direction, a fold line 26 parallel to the Z direction is formed at the upper edge. In addition, on the side surface 17 in the width direction, score lines 27 and 28 are formed at the left and right side edges extending in the Y direction, and are separated from the side surface 14. A score line 29 is formed at the lower edge of the side surface 17. Such a side surface 17 in the width direction can be bent so as to be pushed into the inside of the box main body 12 along the fold line 26.
In FIG. 1, at the four corners of the upper frame 11, superposition guides 33 for superposing the box body 12 are attached.

Next, FIG. 2 is a perspective view showing the bellows partition 16 housed inside the box body 12.
As shown in FIG. 2, the bellows partition portion 16 is configured of a plurality of partition plates 22 and bellows sheets 20 a and 20 b connecting the partition plates 22. The bellows sheets 20a and 20b are joined on the left and right sides toward the front of the partition plate 22, and the bellows sheets 20a and 20b and the adjacent partition plates 22 form a space for storing an article. In the bellows sheets 20a and 20b, folds 35 are formed in parallel with the partition plate 22 between the adjacent partition plates 22 and the ridges and valleys as a whole are formed by bending easily along the folds 35. It is designed to construct a continuous bellows structure in the arrangement direction.
Here, FIG. 5 is a figure which shows the joining structure of bellows sheet 20a, 20b and the partition plate 22 in the bellows partition part 16 by this embodiment. A plurality of ear portions 36 are formed at both end portions of the partition plate 22, and the ear portions 36 are inserted into cut holes 37 formed in the bellows sheets 20a and 20b. With such a structure, the bellows partition 16 can be assembled without using a tape or an adhesive.

  As shown in FIG. 1, the bellows partition portion 16 is accommodated so that the partition plate 22 is parallel to the side surface 17 in the width direction of the box main body 12, and two bellows partition portions 16 so as to be brought close to each side surface 17. Is used. The direction in which each bellows partition 16 extends and contracts is the longitudinal direction (X direction) of the box body 10.

The foldable container by this embodiment is comprised as mentioned above, and demonstrates the effect | action and effect next.
3 and 4 are diagrams showing a series of procedures for folding the foldable container 10 according to the present embodiment when not in use.

In FIG. 3 (a), the collapsible container 10 is shown assembled into use.
The bellows partition 16 is extended in the longitudinal direction of the box body 12 and is held in an open state by the velcro 38 (see FIG. 1). An article is stored in each section partitioned by the partition plate 22.

  In order to fold the foldable container 10, as shown in FIGS. 3 (b) and 3 (c), the bellows partition 16 is folded so as to be close to the side surface 17 of the box body 12, respectively.

  Next, as shown in FIG. 4A, the side surface 17 is pushed into the inside of the box main body 12. The side surface 17 can be easily bent and bounced along the fold line 26. Furthermore, as shown in FIG. 4 (b), the bellows partition portion 16 is set in a horizontal posture while pushing the side surface 17 further.

In this way, when the bellows partition portion 16 is placed on the side surface 17 in a horizontal posture, the longitudinal side surface 14 can be bent.
Therefore, as shown in FIG. 4C, when the side surface 14 is pushed inward, the side surface 14 can be easily folded in two along the fold line 19. Finally, the foldable container 10 can be folded to a flat shape as shown in FIG. 4 (d). In the case of storage, it may be stacked while being thinly folded.

  Here, as shown in part A of FIG. 6, it is preferable to use the superposition guide 33 to press the bellows partition part 16. The folded bellows partition portion 16 is restricted by the superposition guide 33, and therefore does not jump upward.

  As described above, according to the foldable container 10 of the present embodiment, even when the bellows partition portion 16 is in the non-use state, the bellows partition portion 16 can be folded without interference, so storage is possible. Space saving can be achieved without taking up space.

The procedure for assembling from the folded state is as shown in FIG. 4 (d) → FIG. 4 (c) → FIG. 4 (b) → FIG. 4 (a) → As shown in FIG. 3 (c) → FIG. 3 (b) → FIG. 3 (a), they are assembled in the reverse order of folding.

Second Embodiment
Next, a foldable container according to a second embodiment of the present invention will be described with reference to FIGS. 7 to 10.
FIG. 7 shows a perspective view of the collapsible container 10. In this FIG. 7, the bellows partition 16 is shown in the state of being taken out. FIG. 8 is a perspective view showing the bellows partition 16.

  This second embodiment is an embodiment in which small partitions are provided in the storage section of the bellows partition portion 16. The other components are the same as those of the first embodiment, so the same reference numerals are given to the same components and the detailed description thereof will be omitted.

  In FIG. 8, for example, four storage compartments are formed in the bellows partition part 16. Among these, the three storage compartments are further divided into smaller compartments by small partitions 30, 31 made of plastic sheets that are easily bent.

In this embodiment, by combining the orientations of the partitions 30, 31, the arrangement of the partitions can be changed.
That is, in the storage compartments divided by the partition plates 22d, 22c, two small compartments are formed by the convex surfaces of the small partitions 30, 31 facing in the same direction. Each of the small compartments can store an article 40 (see FIG. 9A).
In the storage compartment partitioned by the partition plates 22c and 22b, one subdivision is formed by the convex surfaces of the subdivisions 30 and 31 facing each other in the opposite direction. In this section, relatively large articles 42 can be stored (see FIG. 9 (b)).

  In the storage compartments partitioned by the partition plates 22b, 22a, three subdivisions are formed by facing the convex surfaces of the small partitions 30, 31 so as to face each other. Each compartment can contain relatively small articles 44 (see FIG. 9 (c)).

  As such, by combining the orientations of the small partitions 30 and 31, the arrangement of the small partitions can be diversified. And by putting an article in each small section, articles can be prevented from contacting each other and being broken. Although the above is an example which divided one storage division by two small partitions 30 and 31, three small partitions may be used and the number is not limited to two.

  Although such small partitions 30, 31 can be joined to the partition plates 22a to 22e using a tape, an adhesive or the like, more preferably, as shown in FIG. It joins by the used folding-up piece.

  In FIG. 10 (a), when the partition plate 22 is cut so that two convex shapes having the same step shape are arranged in the same direction, convex shapes whose convex directions are opposite to each other can be formed between the convex shapes. Then, when the incision is turned back, convex folds and raised pieces 43a and 43b are formed on one side, and a convex fold and formed piece 44 is formed on the other. In the direction of the small partition 30, the notches 45a, 45b, 45c are formed on the same straight line in correspondence with the convex folded pieces 43a, 43b, 44.

  As shown in FIG. 10 (b), the small partition 30 is put in the hole formed by the convex folded and raised pieces 43a and 43b to intersect with the partition plate 22, and the ends of the convex folded and raised pieces 43a and 43b Are inserted into the notches 45a and 45c, and the end of the convex folded piece 44 is inserted into the notches 45b.

  After that, when the folded-back pieces 43a, 43b, 44 are folded back so as to be flush with the partition plate 22, as shown in FIG. 10 (c), the small partition 30 can be joined to the partition plate 22. it can.

  In the case of such bonding, in addition to the need for a tape, an adhesive and the like, the small partitions 30 and 31 can be appropriately removed or the orientation can be changed to change the arrangement of the small sections.

  As mentioned above, although the preferred embodiment was mentioned and described about the foldable container concerning the present invention, these embodiments were mentioned as an illustration and the restriction of the range of an invention is not intended. Of course, the novel apparatus, method, and system described in the specification can be implemented in various forms, and furthermore, various omissions, substitutions, and alterations are possible without departing from the spirit of the present invention. is there.
