  The foldable container according to the first aspect of the present invention is a foldable container having a bottom plate, a side wall, and an upper frame that form an article-receiving recess, and the side wall of the foldable container can be rotated to the side of the bottom plate. A pair of two folded side plates that are opposed to each other at the time of standing, and the upper side is rotatably connected to the upper frame. And a pair of tilt side plates that are connected at the corners with the two-fold side plate when standing up and are rotated in the inner direction of the article housing recess when folded, and on the upper surface of the bottom plate, A partition (vertical bottom partition) extending in a direction (longitudinal direction) parallel to the double-folded side plate is formed, and the height of the central portion in the vertical direction of the vertical bottom partition is the lower end when the tilted side plate stands Higher than the height of The longitudinally bottom the longitudinal direction end portions of the partition, characterized in that the cutout avoid interference with the tilt plate lower part is formed at the standing time and the rotation of the tilt plate (tilt).

  According to the present invention, the height of the lower side of the tilt side plate at the time of standing is made lower than the height of the vertical bottom partition, and interference with the lower end of the tilt side plate at the time of standing and turning (tilting) of the tilt side plate is prevented. By forming the notches to be avoided at both longitudinal ends of the vertical bottom partition, the thickness of the bottom plate can be reduced while ensuring the height of the vertical bottom partition. In addition to the slope shape, the shape of the notch may be a flat shape with no partition in the rotation trajectory of the tilt side plate.

  The foldable container according to the second aspect of the present invention is a foldable container having a bottom plate, a side wall, and an upper frame that form an article housing recess, and the side wall of the side wall is rotatable to the side of the bottom plate. A pair of two folded side plates that are opposed to each other at the time of standing, and the upper side is rotatably connected to the upper frame. And a pair of tilt side plates that are connected to the two folded side plates at the corners when standing and are rotated inwardly toward the inside of the article housing recesses when folded, and on the inner side of the two folded side plates A reinforcing rib extending in the vertical direction is formed, and a partition (lateral bottom partition) extending in a direction (lateral direction) parallel to the tilt side plate is formed on the upper surface of the bottom plate. Fold the divider Wherein the notch avoid interference with the reinforcing ribs are formed at the time.

  If the reinforcing rib is formed on the two-fold side plate, the folding height is increased by the amount of the reinforcing rib when folded. Therefore, a reinforcing rib extending in the vertical direction is formed on the inner side of the bi-fold side plate, and a notch in which the reinforcing rib is accommodated when folded is provided in the horizontal bottom partition. The partition overlaps and the folding height can be lowered accordingly.

  The foldable container according to the third aspect of the present invention is a foldable container having a bottom plate, a side wall, and an upper frame that form an article housing recess, and the side wall of the side wall is rotatable to the side of the bottom plate. A pair of two folded side plates that are opposed to each other at the time of standing, and the upper side is rotatably connected to the upper frame.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the foldable container 1 includes a bottom plate 10, a side wall 20, and an upper frame 50 that form an article housing recess 2. The side wall 20 is foldable, and is composed of a pair of two folded side plates 30 that face each other when standing, and a pair of tilt side plates 40 that face each other when standing.

The structure of each part will be described with reference to FIGS.
As shown in FIG. 2C, the bottom plate 10 has a rectangular planar shape. Moreover, as shown to FIG. 2 (A), (B), the bank part 11 with a low height is standingly arranged along the periphery. As shown in FIG. 3A, a convex piece 13 extending along the short side is formed on the inner surface of the bank portion 11 on the short side. As will be described later, a concave portion 41 formed along the lower side of the outer surface of the tilt side plate 40 is engaged with the convex piece 13. On the other hand, as shown in FIG. 3B, a shaft 15 extending in the long side direction is attached to the inner surface of the bank 11 on the long side. As will be described later, the lower side of the bi-fold side plate 30 is rotatably connected to the shaft 15.
The pivot shaft 15 between the double folded side plate 30 and the bottom plate 10 is located at the same height as the convex piece 13 (engagement portion with the lower side of the tilt side plate 40) formed on the inner surface of the short side bank portion 11.

  As shown in FIG. 2C, a plurality of parallel partitions 17 (vertical bottom partitions) extending in the longitudinal direction (vertical direction) of the bottom plate 10 are formed on the upper surface of the bottom plate 10. As shown in FIG. 3A, the vertical bottom partition 17 extends between the convex pieces 13 formed on the inner surfaces of both short side banks 11. The vertical bottom partition 17 is for standing and holding the regenerator material, and has a predetermined height. The shape of the vertical bottom partition 17 will be described later. As shown in the figure, the convex piece 13 formed on the bank portion 11 is formed at a position lower than the maximum height of the vertical bottom partition 17.

  Further, as shown in FIG. 2C, a partition 18 (lateral bottom partition) extending in a direction (lateral direction) orthogonal to the same direction is formed at the center of the upper surface of the bottom plate 10 in the longitudinal direction. . The horizontal bottom partition 18 is composed of two rows of parallel partition plates having the same height as the vertical bottom partition 17. As shown in FIG. 3B, the horizontal bottom partition 18 extends between the rotation shafts 15 on the inner surfaces of both long side banks 11. The shape of the horizontal bottom partition 18 will be described later. The horizontal bottom partition 18 is for forming a gap between the cold storage materials arranged side by side when the cold storage material is a half size.

As shown in FIG. 2, the upper frame 50 is a low rectangular bank-shaped frame member having a rectangular shape that is the same as the bottom plate 10. As shown in FIG. 3 (A), a shaft 51 extending in the short side direction is attached to substantially the center in the height direction of the side surface on the short side of the upper frame 50. The upper side of the tilt side plate 40 is rotatably connected to the shaft 51. Further, as shown in FIG. 3B, a shaft 53 extending in the long side direction is attached to a position slightly above the lower end of the long side surface of the upper frame 50. The upper side of the bi-fold side plate 30 is rotatably connected to the shaft 53. The shaft 51 to which the upper side of the tilt side plate 40 is connected is formed at a position higher than the shaft 53 to which the upper side of the bi-fold side plate 30 is connected. This is because they are stacked on the folded double-fold side plate 30.
As shown in FIG. 2B, an opening 55 serving as a handle is opened at the lower center of the side surface on the short side of the upper frame 50.

The bi-fold side plate 30 includes a horizontally long rectangular upper plate 31 and a lower plate 32 that are connected to each other in the middle step so as to be folded in two. As shown in FIG. 3A, the upper side of the upper plate 31 is rotatably connected to a shaft 53 formed on the long side surface of the upper frame 50. In addition, the lower side of the lower plate 32 is rotatably connected to a rotation shaft 15 formed on the inner surface of the long side bank portion 11 of the bottom plate 10.
Further, a plurality of parallel reinforcing ribs 35 extending in a direction (longitudinal direction) parallel to the side plate are formed on the inner surface of the double folded side plate 30.

  As shown in FIG. 2B, the tilt side plate 40 has a substantially square shape. As shown in FIG. 3 (A), the upper side of the tilt side plate 40 is rotatably connected to a shaft 51 attached to the short side surface of the upper frame 50. It is rotated inward (article housing recess direction) as a center. Furthermore, connection parts (not shown) connected to the side edges of the double-folded side plate when standing are formed on both sides. Further, an outward recess 41 is formed along the lower side of the outer surface. The concave portion 41 engages with the convex piece 13 formed on the inner surface of the short side bank portion 11 of the bottom plate 10 when the tilt side plate 40 is erected.

A plurality of parallel partitions 43 (side plate partitions) extending in the vertical direction are formed on the inner surface of the tilt side plate 40. This side plate partition 43 is for holding the side part of a cool storage material. The side plate partition 43 will be described later.
Further, as shown in FIG. 2B, an opening 45 communicating with the handle opening 55 formed in the upper frame 50 is formed near the center of the upper side of the tilt side plate 40.

A folding method and an assembling method will be described.
When folding, first, the tilt side plate 40 is rotated inward (toward the article housing recess) with respect to the short side of the upper frame 50 (rising or swinging). At this time, for example, the thumb of the hand is passed through the openings 55 and 45 formed in the upper frame 50 and the tilt side plate 40, the upper frame 50 is gripped, and the tilt side plate 40 is pushed inward by a finger other than the thumb. Then, the concave portion 41 on the lower side of the tilt side plate 40 moves away from the convex piece 13 of the bank portion 11 of the bottom plate 10, and the engagement between the tilt side plate 40 and the bottom plate 10 is released. Rotate while sliding in the direction. Then, both the tilt side plates 40 are rotated until they are substantially horizontal with the bottom plate 10 beyond the middle portion of the folded side plate 30. In addition, by the rotation of the tilt side plate 40, the connection between the side of the tilt side plate 40 and the side of the bi-fold side plate 30 is released, and the bi-fold side plate 30 naturally starts to be folded in half. When the upper frame 50 is lowered in accordance with the bifolding, first, the bifold side plate 30 is folded in half and folded on the bottom plate 10. Then, when the upper frame 50 is lowered as it is, the tilt side plate 40 is placed on the upper plate 31 of the folded two-fold side plate 30 in a state of being rotated almost horizontally.

  Finally, as shown in FIG. 4, the upper frame 50 gets on the bank portion 11 of the bottom plate 10. At this time, the rotation shaft 53 of the bi-fold side plate 30 and the rotation shaft 51 of the tilt side plate 40 provided on the upper frame 50 and the rotation shaft 15 of the bi-fold side plate 30 provided on the bank portion 11 of the bottom plate 10 are: , They are all formed on the inner surface side of the top frame 50 and the bank portion 11 of the bottom plate 10 and therefore do not appear on the outer surface when folded. As shown in FIG. 4, the folding height H is a height obtained by adding the thickness H <b> 1 (the height of the bank 11) of the bottom plate 10 and the height H <b> 2 of the upper frame 50.

  The assembling method is the reverse, and the upper frame 50 is gripped and lifted upward with respect to the bottom plate 10. Then, the bi-fold side plate 30 starts to stand straight, and the tilt side plate 40 starts to rotate due to its own weight. And after raising the upper frame 50 until the bifold side plate 30 becomes straight and the tilt side plate 40 rotates almost vertically, the concave portion 41 on the lower side of the tilt side plate 40 is formed on the convex piece 13 of the bank portion 11 of the bottom plate 10. The both sides of the tilt side plate 40 and the side sides of the folded side plate 30 are connected.

Next, the vertical bottom partition 17 and the horizontal bottom partition 18 formed on the upper surface of the bottom plate 10 will be described with reference to FIGS.
As shown in FIG. 3A, the protruding piece 13 (engagement portion between the tilt side plate 40 and the bottom plate 10) formed on the bank portion 11 of the bottom plate 10 is a position lower than the maximum height of the vertical bottom partition 17. Is formed. As described above, when the convex piece 13 (the lower end portion of the tilt side plate 40) is provided at a position lower than the vertical bottom partition 17, when the tilt side plate 40 is rotated, the lower side of the tilt side plate 40 is the vertical bottom partition. It will hit the end. Therefore, in the present invention, the slope-shaped notch 17a that is gradually inclined upward from the end toward the center is formed at the end of the vertical bottom partition 17. Portions other than the cutout 17a are substantially horizontal to the bottom plate 10.

  By forming such a notch (slope) 17a in the vertical bottom partition 17, as shown in FIGS. 5 (A) to 5 (C), the lower side of the tilt side plate 40 rotates over the notch 17a. Since it moves, it does not interfere with the vertical bottom partition 17. In this example, the shape of the notch 17 a is formed in a substantially arc shape substantially along the rotation locus of the lower side of the tilt side plate 40. However, the shape of the notch 17a is not limited to the arc shape along the rotation locus, and a partition may not be provided for the rotation locus.

  Thus, in the present invention, the engaging portion (the convex piece 13) of the bottom plate 10 with the lower side of the tilt side plate 40 is formed at a position lower than the maximum height of the vertical bottom partition 17, and the vertical bottom A notch 17 a is provided at the end of the partition 17. In other words, the height of the engaging portion (convex piece 13) is formed at a low position, which means that the height of the bank portion 11 (height H1 in FIG. 4) can be lowered, and the height when folded is lowered. it can.

With reference to FIG. 6, the case where a notch is not provided in the edge part of the vertical direction bottom partition 17 is demonstrated as a comparison. In this case, as shown in FIG. 6A, the engaging portion (projection piece 13) formed on the bank portion 11 of the bottom plate 10 needs to be formed at a position higher than the vertical bottom partition 17. By doing so, as shown in FIGS. 6B to 6C, the lower side of the tilt side plate 40 passes through the upper surface of the vertical bottom partition 17 when the tilt side plate 40 rotates. However, the height H3 of the bank portion 11 of the bottom plate 10 needs to be equal to or greater than the maximum height of the vertical bottom partition 17.
In the present invention, the folding height can be lowered by the height difference (H3−H1) of the bank portion 11 without changing the height of the container and the height of the partition plate by the above-described configuration. When the container height is the same as the conventional height, the height of the tilt side plate 40 is increased by this difference.

Next, the relationship between the double folded side plate 30 and the bottom plate 10 will be described.
As shown in FIG. 3B, the height of the pivot shaft 15 between the lower plate 32 of the folded side plate 30 and the long side of the bottom plate 10 is the engaging portion (projection piece 13) between the tilt side plate 40 and the bottom plate 10. ) Is the same height. That is, it is at a position lower than the height of the vertical bottom partition 17. Since the height of the vertical bottom partition 17 is the same as the height of the horizontal bottom partition 18, the height of the rotating shaft 15 is lower than the height of the horizontal bottom partition 18.

  Then, when the bi-fold side plate 30 is folded, the reinforcing rib 35 formed on the inner surface of the lower plate 32 hits the lateral bottom partition 18 on the upper surface of the bottom plate 10, and the lower plate 32 is folded substantially parallel to the bottom plate 10. Disappear. Therefore, in the present invention, a notch 18a having a certain width is formed in the vicinity of the inner position by the distance from the end of the horizontal bottom partition 18 to the reinforcing rib 35 from the lower end of the lower plate 32. ing. Accordingly, as shown in FIGS. 7B to 7C, the reinforcing rib 35 formed on the lower plate 32 of the double-fold side plate 30 enters the notch 18 a of the lateral bottom partition 18 when folded. In the completely folded state, as shown in FIG. 7C, the lower plate 32 and the horizontal bottom partition 18 overlap each other in a side view.

  On the contrary, as shown in FIG. 8, when the pivot shaft 15 between the lower plate 32 and the long side of the bottom plate 10 is located higher than the horizontal bottom partition 18, the reinforcing ribs 35 of the lower plate 32 are lateral. Folded on top of directional bottom partition 18. In this case, the height of the bank portion 11 is increased.

  As described above, in the present invention, the folding height can be lowered by reducing the height of the bank portion 11 of the bottom plate 10. However, when the height of the bank portion 11 is lowered, the vertical bottom partition 17 and the horizontal bottom partition 18 formed on the bottom plate 10 interfere with the pivoting operation of the tilt side plate 40 and the folding operation of the two-fold side plate 30. Therefore, notches 17a and 18a are formed in the vertical bottom partition 17 and the horizontal bottom partition 18 to avoid interference.

Next, the side plate partition 43 formed on the tilt side plate 40 will be described with reference to FIGS.
The side plate partition 43 has a substantially rectangular shape and is formed at a position near the upper end of the tilt side plate 40. When the container is folded, as described above, both the tilt side plates 40 are rotated inward (in the direction of storing the article) with respect to the upper frame 50. At this time, as shown in FIG. 4, the lower portions of the tilt side plate 40 overlap each other and are folded substantially parallel to the bottom plate 10. At this time, since the side plate partition 43 is provided at a position where the two side plates 40 do not overlap, that is, a position near the upper end of the side plate 40, the upper side plate 40 is overlapped with the side plate partition 43 of the lower side plate 40. Don't be. In this way, the folding height of the tilt side plate 40 can be lowered.

  In a state where the container is folded, a concave portion surrounded by the upper frame 50 is formed on the upper surface. When stacking the folded containers, the bottom plate 10 of the upper folded container is fitted into the recess to give stability during stacking. As shown in FIG. 4, a folded side plate 40 exists at the bottom of the recess, and a side plate partition 43 projects upward. Then, the depth of the concave portion becomes shallower by the height of the side plate partition 43, so that the bottom plate 10 of the upper folded container hits and stacking stability cannot be obtained.

  In the present invention, the shape of the side plate partition 43 is such that when the tilt side plate 40 is folded, the upper side 43a (the side side when standing) of the side plate partition 43 of the tilt side plate 40 that is stacked on the upper side is substantially horizontal. did. Thereby, the height of the part which protrudes uselessly can be made low. In order to obtain such a shape, as shown in FIG. 3A, when standing, the side plate 43a is placed from the top to the bottom so that the width of the side plate partition 43 becomes narrower from the upper side to the lower side. The shape is inclined outward (in the direction opposite to the article housing recess). The upper side of the side plate partition 43 has a maximum width that acts as a partition.

  Accordingly, as shown in FIG. 9, the bottom plate 10 of the folded container 1 that is stacked on the upper side is fitted into the concave portion in the upper frame 50 of the folded container 1 on the lower side. At this time, the side plate partition 43 of the tilt side plate 40 protruding into the recess does not hit the lower surface of the bottom plate 10 of the upper folded container 1.

The accommodation state of the cold storage material will be described with reference to FIGS. 10 and 11.
In the case of the full-size regenerator material C1, as shown in FIG. 10, the regenerator material C1 has a lower side supported between the vertical bottom partitions 17 formed on the upper surface of the bottom plate 10, and a side side of the tilt side plate 40. It is supported by a side plate partition 43 formed on the inner surface.
In the case of the half-size regenerator material C2, as shown in FIG. 11, the regenerator material C2 has a lower side supported between the vertical bottom partitions 17 formed on the upper surface of the bottom plate 10, and one side is a tilt side plate. It is supported by a side plate partition 43 formed on the inner surface of 40. Further, the regenerator materials C2 arranged side by side are supported by the lateral bottom partition 18 with a gap therebetween.

With the above-described configuration, the folding height can be reduced by about 20 mm compared to a conventional folding container of the same size.
In the embodiment, the example in which the vertical bottom partition, the horizontal bottom partition, and the side plate partition are provided has been described, but only the vertical bottom partition is formed, and the horizontal bottom partition and the side plate partition may not be formed. It is possible.
