JP 2001-270582 A Japanese Patent Laid-Open No. 6-80142

However, in the shipping container of Patent Document 1, there is a problem that an empty tray must be accommodated and returned in the same volume as when transported goods are returned at the time of return, and transport efficiency at the time of return is poor.
Further, the foldable pallet container disclosed in Patent Document 2 cannot use a partition plate that divides the space for storing the transported goods. There is a problem that the transported goods are damaged due to the collision between the goods.

As a result of studying to solve the above problems, the present inventor has made it possible to insert a partition plate that accommodates transported goods individually or in a predetermined assembled state into the tray while returning empty trays and containers. Succeeded in developing a tray and a container using the tray that made it possible to reduce the volume of the original volume.
That is, the present invention is a plurality freely inserted into and removed from the container for transporting the shipment housing, with at the time of transportation can be accommodated are stacked in two stages the shipment in the vertical direction, at the time of return, A tray capable of reducing the height dimension in half , wherein the side wall of the tray is formed so as to be foldable at a height position in the middle of the tray, and from the position of the fold line of the side wall. The upper half side of the upper side and the lower half side below the folding line position of the side wall are respectively raised from the bottom surface, and the upper half side is bent to the lower half side. And is formed on the bottom plate of the tray so as to be bent in a zigzag shape at a height of ½ or less of the height of the tray during transportation. Arranged along the bottom plate of The delivery is partitioned individually or in a predetermined assembled state. On the other hand, at the time of return, a first partition plate formed to reduce the volume by compressing the interval between the zigzag bent portions is provided, Transporting an intermediate bottom plate that forms a bottom plate portion serving as a bottom plate of a transported product stored in the upper stage of the tray by being bent at a portion and a side wall portion having the same height as the upper half of the side wall of the tray. At times, the height position of the bottom plate portion is the height position of the folding line on the side wall of the tray, and at the time of return, the height position of the bottom plate portion is directly above the bottom plate, respectively. Arranged in the same shape as the first partition plate, one end portion in a zigzag direction is fixed to the side wall portion, and transported items arranged along the bottom plate portion during transportation are individually or in a predetermined set On the other hand, at the time of return, the volume can be reduced by compressing the interval between the zigzag bent portions, and the reduced first partition plate can be accommodated on the bottom plate portion. A tray having two partition plates .

A container formed of a hexahedron capable of accommodating a plurality of trays according to claim 1, wherein one side panel of the side panels of the container is formed on a door for opening, and A top panel and a bottom panel are provided so as to be rotatable with respect to the one side panel, and at least one of the side panels excluding the one side panel is a bent side panel that can be bent in the side panel. Each of the door, the top panel, the bottom panel, and the bent side panel is formed to be foldable so that the capacity of the container from which the plurality of trays are taken out can be reduced. It can also be a featured container.

Moreover, the planar view shape after volume reduction is formed in L shape. As a result, when returning a plurality of empty containers, the corner of the hexahedron container containing the tray can be aligned with the corner of the container that has been folded and reduced to an L shape. The container at the time can be made more compact.

Further, the side panel is provided with a locking tool for maintaining the folded state of the door, the top panel, the bottom panel, and the bent side panel. This prevents the folded state from being unraveled during the transportation of the containers that have been reduced in volume by folding each panel.

According to the tray and the container using the same according to the present invention, it is possible to transport the transported goods individually or in a state of being divided into a predetermined collective state, and the tray and the container in an empty state can be efficiently used. Since the volume can be reduced, the transportation cost required for return can be greatly reduced.
In addition, the reduced tray state can be reliably maintained. Furthermore, since the partition plate can be extended and contracted, the partition state of the transported goods and the volume when the partition plate is returned can be made compact, and a plurality of partition plates can be accommodated in the return tray. This is possible, and the intermediate partition plate and the partition plate are not separated. Furthermore, the intermediate bottom plate and the partition plate are not lost at the time of return.

FIG. 1 is a perspective view showing a tray in the present embodiment. FIG. 2 is a development view of the tray shown in FIG.
As shown in FIG. 1, the tray 10 according to the present embodiment is formed in a deep dish shape having a rectangular shape in plan view and an open top surface. The tray 10 is assembled by bending a resin plate or the like formed in the shape shown in FIG. A folding line 22 is formed on the side wall 20 of the tray 10 at a height position in the middle thereof. The folding line 22 is provided at a position where the height of the side wall 20 is divided into two. The side wall 20 is divided into an upper half side 24 and a lower half side 28 via a fold line 22. On the upper half side 24 of the side wall 20, a grip portion 26 is formed for holding the tray 10 or pulling out the tray 10. Further, a hook-and-loop fastener 29 that is a locking tool is attached to the outside of the upper half side 24 of one side wall 20.

Bending pieces 24a and 28a are formed on the upper half side 24 and the lower half side 28 of one opposing side wall 20, respectively. A hook-and-loop fastener, which is a locking tool, is attached to the outer surface of each of the bent pieces 24a and 28a. Hook fasteners 24b and 28b that are paired with hook and loop fasteners attached to the bent pieces 24a and 28a are disposed at both end portions on the inner side surface of the other opposing side wall 21. Each bent piece 24a, 28a is bent inside the other adjacent side wall 21 and attached to the hook-and-loop fasteners 24b, 28b to maintain the box shape.
The hook-and-loop fastener 24 b also forms a pair with the hook-and-loop fastener 29.

The tray 10 assembled as described above is provided with a first partition plate 30 as shown in FIG. 3 and a second partition plate 40 as shown in FIG. By disposing the first partition plate 30 and the second partition plate 40 so that the internal space of the tray 10 can be appropriately divided and used, the transported goods are individually or in a predetermined assembled state It can be transported without damaging the transported goods. In the present embodiment, the internal space of the tray 10 can be divided into two in the height direction. Specifically, the first partition plate 30 shown in FIG. 3 is disposed on the bottom plate 12 of the tray 10, and is positioned at the height of the folding line 22 formed on the side wall 20 of the tray 10. The internal space of the tray 10 can be made into a two-stage structure only by disposing the second partition plate 40 shown in FIG.

As shown in FIG. 3, the first partition plate 30 disposed on the bottom plate 12 of the tray 10 has a shape in which a single long thin plate is folded back into a zigzag shape (bellows shape) for each required length. Since it is formed, it can be expanded and contracted in the direction of the arrow. In the section partitioned by the first partition plate 30 and the bottom plate 12, the transported goods are arranged individually or in a predetermined aggregate state. If the material for forming the first partition plate 30 (thin plate) is rich in shock-absorbing properties, it is possible to alleviate the impact when transported goods collide with each other, so that damage during transportation can be reliably prevented. . It is preferable to provide a fixture such as a hook-and-loop fastener on both end portions of the first partition plate 30 (thin plate) and the inner surface portion of the side wall 20. According to such a structure, since the 1st partition plate 30 can be fixed to the inner surface of the side wall 20, it can maintain a stable state, without a backlash of transportation goods during conveyance.
In addition, when a transport product is set in a section partitioned by the first partition plate 30 and the bottom plate 12, the zigzag portion spreads, and both end portions of the first partition plate 30 may preferably come into contact with the side wall 20 of the tray 10. is there. In the case of transporting only such transported goods, or when there is no concern about the backlash of the transported goods during transportation, it is of course possible to omit the fixing tool for fixing the first partition plate 30. It is.

As shown in FIG. 4, in the second partition plate 40, a part of the partition plate 40 is fixed to the intermediate bottom plate 42. The second partition plate 40 is provided so as to be stretchable on the plane of the intermediate bottom plate 42. Since the shape of the thin plate in the second partition plate 40 is formed in the same shape as the thin plate in the first partition plate 30 described above, detailed description thereof is omitted here.
The intermediate bottom plate 42 is formed by a folding line 44 so as to be bendable. A bottom plate portion 46 and a side wall portion 48 are formed by vertically bending the intermediate bottom plate 42 on the folding line 44. Each dimension of the bottom plate portion 46 is substantially the same as each dimension of the bottom plate 12 of the tray 10. A notch 46 a is formed at the end of the bottom plate portion 46. In addition, each dimension of the side wall portion 48 is substantially the same as each dimension on the upper half side 24 of the side wall 20 of the tray 10. On the side wall portion 48, a grip portion 48 a is formed at a position corresponding to the position of the grip portion 26 on the upper half side 24 of the tray 10. One end portion of the second partition plate 40 (thin plate constituting the second partition plate 40) is fixed to the side wall portion 48 by heat welding or the like. Thus, by providing the grips 26 and 48a on both the tray 10 and the intermediate bottom plate 42, the intermediate bottom plate 42 is always held when the tray 10 is held, so that the intermediate bottom plate 42 is displaced. This is advantageous because it can prevent damage to the transported goods.

If the bottom plate portion 46 of the intermediate bottom plate 42 is disposed at the height position of the folding line 22 of the side wall 20 of the tray 10, it can be used in the same manner as the first partition plate 30 shown in FIG. That is, by using the second partition plate 40, the transported goods can be stored in the inner space of the tray 10 in a state of being stacked in two stages.
The intermediate bottom plate 42 can be easily taken out from the inside of the tray 10 by the notch 46 a formed in the bottom plate portion 46. Similarly to the first partition plate 30, the second partition plate 40 (thin plate constituting the second partition plate 40), the bottom plate portion 46, and the side wall portion 48 are also formed using a material having high buffering properties. Yes.

FIG. 5 is an explanatory diagram showing the state of the container when transporting a transported item.
The container 50 in the present embodiment is formed in a hexahedron that can accommodate 16 trays 10 on the front side and the back side in an array of 4 rows and 2 columns. The container 50 is formed in a cubic shape in which a panel is attached to the frame W. As shown in FIG. 5, the tray 10 accommodated in the container 50 is accommodated so as to be drawable (insertable / removable). The surface from which the tray 10 is pulled out is formed so as to be able to be closed by a door 58 attached in a double-opening manner (the door 58 does not necessarily have to be double-opening and may be single-opening). The frame body W on the bottom surface of the container 50 is provided with casters 60 used when the container 50 is transported and legs 62 for transporting the containers 50 in a stacked manner.

  In the present embodiment, as described above, the tray 10 when transporting the transported goods has a two-stage structure inside the tray 10 in the height direction. If the empty container 50 and the tray 10 are to be returned as they are after the transported goods are taken out at the transport destination, the volume with respect to the loaded weight increases, which is uneconomical. In the tray 10 according to the present embodiment, since the side walls 20 and 21 of the tray 10 are formed to be bendable at the folding line 22 portion, when the container 50 and the tray 10 are returned with empty load, the tray 10 and the container The volume can be reduced by folding 50 respectively.

The volume reduction of the tray 10 will be described. FIG. 6 is an explanatory view showing a tray folding method. FIG. 7 is an explanatory view showing a state in which the tray is reduced in volume. FIG. 8 is an explanatory view showing a state where the volume of the partition plate is reduced.
First, the surface fastener and the surface fastener 24b of the bent piece 24a on the upper half side 24 of the tray 10 are peeled off, and the upper half side 24 of the side walls 20 and 21 is bent 90 degrees in the direction of the arrow in FIG. A hook-and-loop fastener 29 is attached to the outer surface of one opposing side wall 20. Since this hook-and-loop fastener 29 is paired with the hook-and-loop fastener 24b of the other opposing side wall 21, the upper half side 24 of the side walls 20 and 21 covers the top of the tray 10 as shown in FIG. It can be fixed with. The height of the tray 10 in this state is half the height of the tray 10 when transporting the transported goods.

Further, the first partition plate 30 for the second partition plate 40, the bottom plate of the intermediate bottom plate 42 the first partition plate 30 is disposed on the upper side of the tray 10 disposed on the lower side of the tray 10 If the first partition plate 30 and the second partition plate 40 are respectively contracted on the portion 46, the space for one first partition plate 30 or the second partition plate 40 is obtained. Can be accommodated. The first partition plate 30, the second partition plate 40, and the intermediate bottom plate 42 thus reduced in volume can be stored in the internal space of the tray 10 in the state shown in FIG. The tray 10 in the state shown in FIG. 7 has an upper opening covered with the folded upper half side 24, so that it is intermediate between the first partition plate 30 and the second partition plate 40 accommodated in the tray 10. This is convenient because the bottom plate 42 is not lost.

By the above, the 1st partition plate 30 and the 2nd partition plate 40 at the time of return, and the intermediate | middle bottom plate 42 can be accommodated in about a half volume with respect to the occupation volume at the time of conveying a transported article. The first partition plate 30, the second partition plate 40, and the intermediate bottom plate 42 are accommodated, and the reduced volume tray 10 can of course be accommodated in the container 50. As shown in FIG. 9, the container 50 at the time of return is in a state in which the trays 10 are accommodated in an array of 8 rows and 2 columns. That is, the tray 10 for two containers 50 is accommodated in one container 50.

A method for returning the empty container 50 from which the tray 10 has been taken out will be described. FIG. 10 is an explanatory diagram showing the state of the container before return. 11-13 is explanatory drawing which shows the folding procedure of a container. FIG. 14 is an explanatory diagram showing a state in which the container is folded.
The container 50 includes a top panel 54, a bottom panel 52, and a side panel 56 formed by attaching a panel member to the frame body W. Each of the frame bodies W is rotatably provided by a hinge or the like (not shown). In the present embodiment, the bottom panel 52 and the top panel 54 are rotatable in the vertical direction with respect to the rear side panel 56a.

  In addition, a central partition plate 59 is disposed in an intermediate portion between the left and right side panels 56b and 56c of the side panel 56. The central partition plate 59 is provided in parallel with the left and right side panels 56b and 56c so as to bisect the left and right side panels 56b and 56c. The central partition plate 59 is detachable from the container 50. The left and right side panels 56b and 56c and the central partition plate 59 are provided with a guide plate 57 that guides the tray 10 when the tray 10 is accommodated. The guide plate 57 is disposed at the same interval as the height interval of the tray 10 when the transported goods are conveyed.

  The side panel 56c located on the right side has an auxiliary frame HW provided in the panel. The auxiliary frame HW extends in the vertical direction of the right side panel 56c, and divides the right side panel 56c into left and right parts. The auxiliary frame HW is rotatably connected by a hinge (not shown). The right side panel 56c thus formed is a bent side panel that can be bent in the plane of the side panel 56c. As shown in FIG. 11, the guide plate 57 of the right side panel 56c is partially cut out at the auxiliary frame HW, so that there is no hindrance to the folding of the right side panel 56c.

Next, a procedure for folding the container 50 will be described.
First, all the trays 10 are pulled out from the container 50 in a state where the transported goods are conveyed. After removing all the trays 10 from the container 50, as shown in FIG. 11, the top panel 54 is rotated around the upper edge of the back panel 56a (also the side panel 56a). The rotated upper panel 54 is fixed to the outer surface of the rear panel 56a. Since the frame W is provided with a locking tool (not shown), the state after the upper panel 54 is rotated outside the rear panel 56a is reliably maintained.
After rotating the upper panel 54, the central partition plate 59 is removed from the frame body W of the container 50.

  Next, as shown in FIG. 12, the bottom panel 52 is rotated around the lower edge of the back panel 56a (in the direction of arrow A) to fix the bottom panel 52 to the inner surface of the back panel 56a. The bottom panel 52 is also reliably maintained in a state where it is rotated to the inner surface of the back panel 56a by a locking tool (not shown). Subsequently, the door 58 connected to the front side of the left and right side panels 56b and 56c is rotated to the outer side of the left and right side panels 56b and 56c (directions of arrows B and C). Similarly to the top panel 54 and the bottom panel 52, the door 58 is fixed in a rotated state by a locking tool (not shown) provided on the frame.

Next, as shown in FIG. 13, the central partition plate 59 removed from the container 50 is disposed further inside the bottom panel 52 and fixed to the bottom panel 52 with a binding tool (not shown) such as a band.
Subsequently, the right side panel 56c, which is a bent side panel, is rotated around the rotation axis of the auxiliary frame HW (in the direction of arrow D), and the right side panel 56c is folded toward the inside of the container 50. As a result, the right side panel 56c and the back panel 56a sandwich the central partition plate 59. The right side panel 56c is also reliably maintained in a folded state by a locking tool (not shown). When the right side panel 56c is fixed by a locking tool, the central partition plate 59 may not be fixed to the bottom panel 52 by a binding tool or the like.

The container 50 folded as shown in FIG. 14 has a substantially L shape in plan view. The planar view shape here refers to a shape in a state viewed from above the upper surface panel 54 of the container 50. As described above, since the shape of the container 50 in the plan view is L-shaped, the occupied area and the occupied volume at the time of return are greatly reduced compared to the occupied area and the occupied volume of the container 50 at the time of transporting the transported goods. Can do.
Specifically, as shown in FIG. 15, the container 50 described in the present embodiment has an occupied area and an occupied area of the container 50 at the time of return with respect to an occupied area and an occupied volume of the container 50 at the time of transporting the transported goods. The volume can be halved. Therefore, it is possible to greatly reduce the transportation cost when returning the container 50 and to greatly save the distribution cost.

As described above, the tray 10 and the container 50 using the tray 10 according to the present invention have been described in detail based on the embodiments. However, the present invention is not limited to the above embodiments. Needless to say, even if modifications are appropriately made to the embodiments within the scope not changing the gist of the invention, they belong to the technical scope of the present invention.
For example, a fold line 22 is formed on the side wall 20 of the tray 10 described in the above embodiments at a height position that divides the height direction of the side wall 20 into two. The height of 20 may not be formed at the position where the height is divided into two. For example, it is of course possible to provide the height of the side wall 20 at three heights or at the height of the side wall 20 divided into four or more. If the folding line 22 is formed at such a position, the volume of the tray 10 after the folding process can be further reduced, and a large number of trays 10 at the time of return can be accommodated in one container 50. It is more convenient because the efficiency is further improved.

In the present embodiment, when the container 50 is folded, only the right side panel 56c is folded in the panel plane (that is, the configuration of the container 50 having one bent side panel). However, as shown in FIG. 16, the left side panel 56b can be a bent side panel that can be folded in the plane of the panel, like the right side panel 56c. In this case, the folding position of the left side panel 56b (positioning position of the auxiliary frame HW) is the right side panel in which the inner side surface (guide 57) of the left side panel 56b after folding is already folded. It is preferable that the position be in contact with the outer surface of 56c (or door 58).
By adopting such a form, the planar view shape of the container 50 at the time of return becomes a plate shape, so that the loading efficiency into the transporting means can be further improved. Further, if the volume of the tray 10 can be reduced, the occupied area and occupied volume of the container 50 at the time of return can be reduced to a fraction of the occupied area and occupied volume of the container 50 at the time of transporting the transported goods. Become.

Furthermore, instead of the first partition plate 30 disposed on the bottom plate 12 of the tray 10, a second partition plate 40 formed integrally with the bottom plate portion 46 can be used. According to this, even if the bottom plate 12 of the tray 10 does not have buffering properties, the buffering action by the bottom plate portion 46 can be obtained, so that the conveyed product can be transported in a more suitable state.
Furthermore, when setting the transport goods on the tray 10, in addition to this embodiment in which the transport goods are set in all the sections of the first partition plate 30 and the second partition plate 40 , every other section or It is good also as a form which sets transportation goods in every other division. According to this form, the effect of the impact on the transported goods can be further reduced. Further, it is more preferable that the transported goods are arranged so as not to overlap each other above and below the tray 10.
