BEST MODE FOR CARRYING OUT THE INVENTION

[0013] The present invention relates to a module container, a tray container used for this module container, and a folding container. Hereinafter, the module container, the tray container, and the folding container according to an embodiment of the present invention will be described based on FIGS. 1 to 11A.

[0014] (1) Module Container (Overview) As shown in FIG. 1, the module container 7 includes a tray container 1 and a folding container 4. The tray container 1 is a container with a shallow depth as shown in FIG. 2A, and the folding container 4 is a container with a depth deeper than that of the tray container 1 as shown in FIG. 5. The folding container 4 is configured to be deformable between a folded state and an assembled state. The module container 7 is a combination (set) of at least one tray container 1 and at least one folding container 4. As shown in FIG. 1, the module container 7 is characterized in that the tray container 1 constituting the module container 7 and the folded state of the folding container 4 constituting the module container 7 can be fitted in a predetermined fitting state. The module container 7 (the tray container 1 and the folding container 4) is formed of resin. As the resin forming the module container 7, polypropylene or polyethylene is preferable, but it is not particularly limited to these resins. Further, the module container 7 may contain not only resin but also a part of a material other than resin such as metal, wood material (including solid wood), glass, etc.

[0015] Details of the module container 7 will be described later.

[0016] (2) Tray Container As shown in FIGS. 2A to 4, the tray container 1 has a bottom wall portion 10 having a rectangular shape (square shape or rectangular shape) in plan view, a pair of first upright portions 2, and a pair of second upright portions 3. In the present embodiment, as shown in FIG. 3A, the bottom wall portion 10 is a plate-like (particularly, flat plate-like) member having a rectangular shape in plan view.

[0017] Here, for convenience, as shown in FIG. 2A, directions are defined. That is, with reference to the center of the bottom wall portion 10 of the tray container 1, the placement surface side is taken as upward and the opposite side is taken as downward. Also, the direction in which a pair of sides (long sides in the present embodiment) extend is taken as the first direction D1, and the direction in which the other pair of sides (short sides in the present embodiment) extend is taken as the second direction D2.

[0018] The bottom wall portion 10 may have through holes or openings formed therein that penetrate vertically in part, or the entire bottom wall portion 10 may be formed in a mesh shape. Further, ribs having a lattice shape in plan view (bottom view) may be formed downward on the lower surface of the bottom wall portion 10.

[0019] As shown in FIG. 4A, the first upright portion 2 stands up from a pair of first sides 11 facing each other of the bottom wall portion 10 and has a first height H1. As shown in FIG. 2A, the first upright portion 2 has an outer wall 21, an upper wall 22, and an inner wall 23 that form a U-shaped opening downward in a cross section orthogonal to the first direction D1.

[0020] The first upright portion 2 has a first upright portion hinge 20. In the present embodiment, the first upright portion hinge 20 is formed on the upper wall 22 of the first upright portion 2. As will be described later, when the tray container 1 is used as the bottom member 40 of the folding container 4, the first side wall member 5 of the folding container 4 is rotatably connected to the first upright portion hinge 20. When the tray container 1 is used alone, the first upright portion hinge 20 is not used.

[0021] As shown in Figure 4A, the second upright portion 3 has a second height H2 that is higher than the first height H1, rising from the other pair of opposing second sides 12 of the bottom wall portion 10. As shown in Figure 2A, the second upright portion 3 has an outer wall 31, an upper wall 32, and an inner wall 33 that form a U-shape and open downwards in a cross section perpendicular to the first direction D1.

[0022] The second upright portion 3 has a second upright portion hinge 30. In this embodiment, the second upright portion hinge 30 is formed on the upper wall 32 of the second upright portion 3. As will be described later, when the tray container 1 is used as the bottom member 40 of the folding container 4, the second upright portion hinge 30 is rotatably connected to the second side wall member 6 of the folding container 4. When the tray container 1 is used on its own, the second upright portion hinge 30 is not used.

[0023] As shown in Figure 4B, the second upright portion 3 has a recess 34. Specifically, the second upright portion 3 (outer wall 31) has a recess 34 that is recessed inward from the outer surface. The recess 34 has a height H21 that is 1 / 3 or more (preferably 1 / 2 or more) of the second height H2. The recess 34 is located at the lower end of the outer surface of the second upright portion 3 (outer wall 31) in the vertical direction.

[0024] In the second direction D2, the recess 34 is located in a part of the second upright portion 3 (in the illustrated example, in the central portion). The length (width) of the recess 34 in the second direction D2 may be formed over the entire width of the second upright portion 3.

[0025] As shown in Figure 2A, the upper end position of the recess 34 on the outer surface of the second upright portion 3 is lower than the upper end position of the outer surface of the first upright portion 2 (outer wall 21).

[0026] As shown in Figure 2B, a cavity 35 that opens downward is formed above the recess 34. The portion of the second upright portion 3 (outer wall 31) above the recess 34 functions as a handle, and when the handle is grasped, the fingers are accommodated in the cavity 35. As shown in Figure 11A, in a cross-section perpendicular to the second direction D2 in the portion of the second upright portion 3 without the recess 34, an opening 36 that opens downward is formed at the lower end of the second upright portion 3 between the lower end of the outer wall 31 and the lower end of the inner wall 33.

[0027] Furthermore, as shown in Figure 8, in a cross-section perpendicular to the first direction D1 of the first upright portion 2, an opening 25 is formed at the lower end of the first upright portion 2, which opens downward between the lower end of the outer wall 21 and the lower end of the inner wall 23.

[0028] (3) Foldable container As shown in Figures 5 to 7B, the folding container 4 has a bottom member 40 that is rectangular in plan view, a pair of first side wall members 5, and a pair of second side wall members 6. In this embodiment, as shown in Figure 5, the bottom member 40 is a plate-shaped (particularly flat) member that is rectangular in plan view. The bottom member 40 is made from another tray container 1 of the same type as the tray container 1. Note that "another tray container 1 of the same type as the tray container 1" means, for example, another tray container 1 that is molded using the same mold that molds one tray container 1. The description of the bottom member 40 alone is the same as the description of the tray container 1 above, so it will be omitted.

[0029] As shown in Figure 5, the first side wall members 5 rise from the first side 11 (see Figure 6B) of the tray container 1, which serves as the bottom member 40. The second side wall members 6 rise from the second side 12 (see Figure 6B) of the tray container 1, which serves as the bottom member 40.

[0030] As shown in Figure 7A, the first side wall member 5 has a first side wall hinge 51 at its lower end. The first side wall hinge 51 is rotatably connected to the first upright hinge 20 (see Figure 2A) of the tray container 1, which serves as the bottom member 40.

[0031] As shown in Figure 7B, the second side wall member 6 has a second side wall hinge 61 at its lower end. The second side wall hinge 61 is rotatably connected to the second upright hinge 30 (see Figure 2A) of the tray container 1, which serves as the bottom member 40.

[0032] The folding container 4 is configured to be transformed into a folded state by first rotating the first side wall member 5 relative to the bottom member 40 and placing it on top of the bottom member 40, and then rotating the second side wall member 6 relative to the bottom member 40 and placing the pair of second side wall members 6 on top of the pair of first side wall members 5, starting from the assembled state shown in Figure 5.

[0033] Furthermore, the folding container 4 is configured to be transformed from the folded state shown in Figures 6A and 6B into an assembled state by rotating the second side wall member 6 relative to the bottom member 40 to make it stand upright, and then rotating the first side wall member 5 relative to the bottom member 40 to make it stand upright.

[0034] The height H5 of the first side wall member 5 shown in Figure 7A is longer than half the length of the bottom member 40 (tray container 1) in the second direction D2. As shown in Figure 8, in the folded state, for the pair of first side wall members 5, 5 that are folded before the pair of second side wall members 6, 6, either of the two first side wall members 5, 5 may be folded first. The folded pair of first side wall members 5, 5 overlap vertically in the second direction D2 in part.

[0035] The first side wall member 5A, which is folded first, slopes downward from the first side wall hinge 51 to its tip. The first side wall member 5B, which is folded later, is flat (parallel to the bottom wall 10) or slopes downward from the first side wall hinge 51 to its tip.

[0036] The height H6 of the second side wall member 6 shown in Figure 7B is shorter than half the length of the bottom member 40 (tray container 1) in the first direction D1. As shown in Figures 6A and 6B, after the pair of first side wall members 5A and 5B are folded, the pair of second side wall members 6 and 6 are folded. The folded pair of second side wall members 6 and 6 are placed in contact with the first upright portion 2. Also, the folded pair of second side wall members 6 and 6 are separated by a gap between their ends. That is, the folded pair of second side wall members 6 and 6 do not overlap in the vertical direction.

[0037] The height (vertical length) H5 of the first side wall member 5 (excluding the first side wall hinge 51) shown in Figure 7A is higher than the height (vertical length) H6 of the second side wall member 6 (excluding the second side wall hinge 61) shown in Figure 7B.

[0038] As shown in Figure 5, the combined height of the first upright section 2 (H1) and the first side wall member 5 (H5) is approximately equal to the combined height of the second upright section 3 (H2) and the second side wall member 6 (H6) (of course, they may be exactly equal). As a result, when the folding container 4 is assembled, the upper surface of the first side wall member 5 and the upper surface of the second side wall member 6 are located on the same plane.

[0039] Furthermore, the height from the top surface of the bottom wall portion 10 to the first upright portion 2 is greater than twice the thickness of the first side wall member 5.

[0040] As shown in Figure 3B, for any one corner portion 13 in a plan view of the bottom wall portion 10 of the tray container 1, which serves as the bottom member 40, the first distance L1 is longer than the second distance L2. The first distance L1 is the distance from the first upright hinge 20 closest to the corner portion 13 to the corner portion 13. The second distance L2 is the distance from the second upright hinge 30 closest to the corner portion 13 to the corner portion 13.

[0041] To explain in more detail, when defining the first distance L1 and the second distance L2 for each of the four corner sections 13, the starting point on the corner section 13 side is defined as the intersection line (intersection point 130) of the virtual extension plane that is on the same plane as the outer surface of the outer wall 21 of the first upright section 2 and the virtual extension plane that is on the same plane as the outer surface of the outer wall 31 of the second upright section 3. Since this intersection line is a point when viewed from the vertical direction, it will be described as intersection point 130 below. The first distance L1 is the distance from intersection point 130 to the end of the first upright section hinge 20 on the intersection point 130 side. The second distance L2 is the distance from intersection point 130 to the end of the second upright section hinge 30 on the intersection point 130 side.

[0042] By forming the first distance L1 to be longer than the second distance L2, the displacement of the second side wall member 6 when the folded folding container 4 is twisted can be suppressed. That is, since the second upright portion 3 is higher than the first upright portion 2, when the folding container 4 is twisted, the deformation of the portion of the second upright portion 3 that is connected to the second upright portion hinge 30 is greater than the deformation of the portion of the first upright portion 2 that is connected to the first upright portion hinge 20, and the displacement of the end of the second side wall member 6 connected to the second upright portion hinge 30 is greater. Therefore, by making the second distance L2 shorter than the first distance L1, and shortening the length from the connecting portion (second side wall hinge 61) of the second side wall member 6 connected to the second upright hinge 30 to the side edge of the second side wall member 6, the range of movement of the second side wall member 6 from the second side wall hinge 61 to the side edge is shortened, and the displacement of the side edge of the second side wall member 6 when the folding container 4 is twisted can be suppressed.

[0043] As shown in Figures 2 to 3B, the second upright portion 3 extends in the second direction D2. The end of the second upright portion 3 in the second direction D2 is bent in the first direction D1 along the first upright portion 2, forming an L-shape in plan view. This improves the rigidity and strength of the folding container 4 (especially its rigidity and strength against twisting), and makes the folding container 4 less susceptible to the effects of twisting even when the first distance L1 > second distance L2.

[0044] Furthermore, the first upright portion 2 extends in the first direction D1. At the end of the first upright portion 2 in the first direction D1, a triangular-shaped reinforcing portion 24 is formed in side view, sloping upward from the upper surface of the first upright portion 2 to the side surface of the second upright portion 3, and continuing to the side surface of the second upright portion 3. This improves the rigidity and strength of the folding container 4 (especially its rigidity and strength against torsion), making the folding container 4 less susceptible to the effects of torsion.

[0045] (4) Stacking of tray containers As shown in Figure 9, the multiple tray containers 1 are arranged so as to overlap in a plan view and are configured to fit together in a predetermined fitted state. Specifically, as shown in Figure 4A, the lower part of the bottom wall portion 10 of the upper tray container 1 fits between the pair of second upright portions 3 of the lower tray container 1, and the lower surface of the second upright portion 3 of the upper tray container 1 rests on the upper surface of the second upright portion 3 of the lower tray container 1. As shown in Figure 3B, the end of the inner surface of the inner wall 33 of the second upright portion 3 on the first upright portion 2 side is curved away from the outer wall 31. This prevents the second upright portion 3 of the upper tray container 1, which is fitted between the pair of second upright portions 3 of the lower tray container 1, from shifting in the second direction D2 and falling out of the lower tray container 1.

[0046] This allows multiple empty tray containers 1 to be stacked and transported. Alternatively, multiple tray containers 1 may be stacked and transported with items placed in at least one of them.

[0047] (5) Stacking of folding containers As shown in Figure 10, the multiple folded containers 4 are arranged so as to overlap in a plan view, and their bottom members 40 can be fitted together in a predetermined fitted state. Specifically, similar to stacking tray containers, the lower part of the tray container 1 that constitutes the bottom wall portion 10 of the upper folded container 4 fits between the pair of second upright portions 3 of the tray container 1 that constitute the bottom wall portion 10 of the lower folded container 4, and the lower surface of the second upright portion 3 of the upper tray container 1 rests on the upper surface of the second upright portion 3 of the lower tray container 1. Also, similar to the case of stacking tray containers, the second upright portion 3 of the tray container 1 that constitutes the bottom wall portion 10 of the upper folded container 4, which is fitted between the pair of second upright portions 3 of the tray container 1 that constitute the bottom wall portion 10 of the lower folded container 4, is prevented from shifting in the second direction D2 and falling off the lower tray container 1. In other words, the predetermined fitting state when stacking the folding containers 4 is the same as the predetermined fitting state when stacking the tray containers 1.

[0048] This allows the tray containers 1 and folding containers 4 to be mixed together and stacked, and then transported, for example, by placing them on a trolley 8.

[0049] Furthermore, as shown in Figure 1, a gap 71 is formed between the upper folding container 4 and the lower tray container 1 in the stacked configuration, penetrating in the second direction D2 between both second upright portions 3. Also, a gap 72 is formed between the upper tray container 1 and the lower folding container 4 in the stacked configuration, penetrating in the second direction D2 between both second side wall members 6 of the lower folding container 4.

[0050] As a result, when a worker transports a trolley 8 on which tray containers 1 and folding containers 4 are stacked, even if the tray containers 1 and folding containers 4 are stacked higher than the worker's eye level, the opposite side of the stacked tray containers 1 and folding containers 4 can be seen through the gap 71 or gap 72, improving visibility and making transportation easier.

[0051] (6) Stacking of modular containers (tray containers and folding containers) As shown in Figure 1, the tray container 1 and the folded folding container 4 that constitute the module container 7 are arranged so that, in a plan view, the bottom members 40 of the tray container 1 and the folded folding container 4 overlap, and they are configured to be able to be fitted together in a predetermined fitted state. The predetermined fitted state in this case is the same as the predetermined fitted state when stacking the folding containers 4 and the predetermined fitted state when stacking the tray containers 1 described above.

[0052] (7) Effects In the aforementioned modular container 7, deep folding containers 4 and shallow tray containers 1 can be used in combination. Furthermore, these can be stacked and transported together. Additionally, by using common components for the bottom members 40 of the tray containers 1 and folding containers 4, design costs can be reduced.

[0053] (modified version) Next, a modified example of the above-described embodiment will be explained.

[0054] The bottom wall portion 10 of the tray container 1 (and the bottom member 40 of the folding container 4) may be square in shape when viewed from above. Also, the bottom wall portion 10 (bottom member 40) does not have to be a strict rectangle in shape when viewed from above.

[0055] In the embodiment described above, the first side 11 was the longer side and the second side 12 was the shorter side, but the first side 11 may be the shorter side and the second side 12 may be the longer side.

[0056] The assembled folding container 4 of the tray container 1 may be arranged so that, in a plan view, the tray container 1 and the bottom member 40 of the folded folding container 4 overlap, and can be fitted together in a predetermined fitted state.

[0057] The material of the module container 7 (tray container 1 and folding container 4) is not limited to resin.

[0058] A recess similar to the recess 34 may be formed in the first upright portion 2. However, in this case, the height of the recess does not have to be the same as the height H21 of the recess 34. The height H21 and width of the recess 34 are not particularly limited. Furthermore, the recess 34 has any configuration and does not have to be formed in the second upright portion 3.

[0059] As shown in Figure 11B, the second upright portion 3 has an upper wall 32 and an inner wall 33, but no outer wall 31 (see Figure 11A). Instead of an outer wall 31, a rib 37 protruding outward from the outer surface of the inner wall 33 may be formed. The rib 37 is a rib extending in the second direction D2, and in the illustrated example, two ribs are formed spaced apart vertically, but the number and position are not limited. The rib 37 may be formed on the outer surface of the second upright portion 3 (inner wall 33) along the entire length of the second direction D2, or it may be formed in part of the second direction D2.

[0060] Similarly, in the first upright portion 2, although an upper wall 22 and an inner wall 23 are formed, an outer wall 21 (see Figure 8) is not formed, and instead of an outer wall 21, a rib (not shown) protruding outward from the outer surface of the inner wall 23 may be formed. The ribs formed on the first upright portion 2 are ribs extending in the first direction D1, and it is preferable that two ribs are formed in the same vertical positions as the ribs 37, but the number and position are not limited. The ribs formed on the first upright portion 2 may be formed on the outer surface of the first upright portion 2 (inner wall 23) along the entire length of the first direction D1, or they may be formed in part of the first direction D1.

[0061] (summary) As is clear from the embodiments and their variations described above, the module container (7) of the first embodiment comprises a tray container (1) and a folding container (4). The tray container (1) has a rectangular bottom wall portion (10) in plan view, a pair of first upright portions (2), and a pair of second upright portions (3). The first upright portions (2) each rise from a pair of opposing first sides (11) of the bottom wall portion (10) and have a first height (H1). The second upright portions (3) each rise from another pair of opposing second sides (12) of the bottom wall portion (10) and have a second height (H2) that is higher than the first height (H1). The first upright portions (2) have a first upright portion hinge (20). The second upright portions (3) have a second upright portion hinge (30). The folding container (4) has a bottom member (40), a pair of first side wall members (5), and a pair of second side wall members (6). The bottom member (40) is made of another tray container (1) of the same type as the tray container (1). The first side wall members (5) each stand up from the first side (11) of the tray container (1) which serves as the bottom member (40). The second side wall members (6) each stand up from the second side (12) of the tray container (1) which serves as the bottom member (40). The first side wall members (5) are rotatably connected to the first upright hinge (20) of the tray container (1) which serves as the bottom member (40). The second side wall members (6) are rotatably connected to the second upright hinge (30) of the tray container (1) which serves as the bottom member (40). The first side wall member (5) is rotated relative to the bottom member (40) and placed on top of the bottom member (40), and then the second side wall member (6) is rotated relative to the bottom member (40) and placed on top of the pair of first side wall members (5), thereby transforming it into a folded state. The second side wall member (6) is rotated relative to the bottom member (40) and placed upright, and then the first side wall member (5) is rotated relative to the bottom member (40) and placed upright, thereby transforming it into an assembled state. Multiple tray containers (1) are arranged to overlap in a plan view and can be fitted together in a predetermined fitted state.
