Description

[Technical Field]

[0001] The present invention relates to a transport container that can store and transport products, and more particularly to a transport container that can be stacked with other types of containers. [Background technology]

[0002] Transport containers (also called containers) are used to transport food products such as fresh produce and prepared foods, as well as daily necessities. Transport containers come in a variety of shapes and sizes, and one type is known as the 180° rotating container.

[0003] This type of transport container allows the upper container to be stacked on top of the lower container by overlapping the upper and lower containers in the same shape direction, for example, when transporting or storing products, while when the boxes are empty, the upper container can be nested inside the lower container by rotating one of the containers horizontally 180 degrees and overlapping them (see, for example, Patent Document 1). This structure allows for the stable transport and storage of a large number of products, and also saves storage space when the boxes are empty.

[0004] The nestable and stackable transport containers are rectangular with an open top, have a plurality of support legs extending outward from the sidewalls, and have a plurality of pockets on the inner circumferential surface of the sidewalls. Depending on the container shape, a top recess recessed from the top end is formed in the flange of the opening edge of the container. In the stacked state, the support legs of the upper container rest on the top surface of the flange or the top recess of the lower container, and in the nested state, the support legs of the upper container overlap the pockets of the lower container.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-137481 Summary of the Invention [Problem to be solved by the invention]

[0006] Incidentally, various types of containers are used as transport containers that can be nested and stacked with each other at various business establishments where products and the like are transported. Typically, transport containers are classified by size, but even containers of similar sizes may have different widths and positions of their support legs due to differences in model numbers or manufacturers, making them non-stackable. When non-stackable containers are mixed at distribution sites, it is necessary to prepare stackable containers, which requires work and space.

[0007] The present invention has been made in consideration of the above circumstances, and aims to provide a transport container that can prevent a decrease in work efficiency even when different types of containers are mixed in. [Means for solving the problem]

[0008] The transport container of the present invention is a rectangular container having an open top and side walls with flanges formed at the open ends, and is capable of being nested and stacked. The transport container has support legs that protrude outward from the outer peripheral surface of the side walls, an upper end recess formed on the inner edge of the flange from the upper end, and a pocket formed on the inner peripheral surface of the side walls extending in the vertical direction, with an upper part that opens to the bottom of the upper end recess and capable of accommodating the support legs. The transport container has a shape different from that of the transport container and is mutually reciprocal. The transport container is stackable relative to each of the first container and the second container which are not stackable relative to each other, and when stacked with these containers in the stacking direction, the upper end recess of the transport container is formed so that the support legs of the first container and the support legs of the second container are placed on the upper end recess, and the support legs of the transport container are formed so that they are placed on the upper surface or upper end recess of the flange portion of the first container and the upper surface or upper end recess of the flange portion of the second container, respectively.

[0009] In this specification, "nestable" means that when upper and lower containers are stacked in the nesting direction, the upper container can be stacked horizontally, and also includes the concept of being able to store the upper container inside the lower container, thereby reducing the storage space of the lower container (nested state). Furthermore, "stacking in the nesting direction" means stacking the upper and lower containers so that their orientations are aligned and the positional relationship between the support legs and pockets on one side (e.g., the short side) is the same for both the upper and lower containers.

[0010] In this specification, "stacking" means that when upper and lower containers are stacked in the stacking direction, the upper container can be stacked horizontally, and is a concept that also includes the ability to stack an upper container on top of a lower container (stacking state) while maintaining storage space for the lower container. Also, "stacking in the stacking direction" means stacking the upper and lower containers with the same orientation and such that the positional relationship between the support legs and pockets on one side (e.g., the short side) is different between the upper and lower containers.

[0011] Furthermore, the notion that the first container and the second container cannot be stacked with each other means, for example, that when the first container is placed on the top tier, the support legs of the first container cannot be placed on the top surface of the flange portion or the upper end recess of the second container, and the first container cannot be stacked horizontally. This also includes a relationship in which, even if the first container and the second container can be stacked precisely, the first container will get stuck inside the second container if it is slightly misaligned due to clearance, etc. The same applies when the second container is placed on the top tier.

[0012] The term "mutually stackable" for the transport container with respect to each of the first container and the second container means that the transport container can be stacked horizontally with respect to the first container whether it is on the upper or lower tier, and can be stacked horizontally with respect to the second container whether it is on the upper or lower tier. In other words, in this case, the transport containers can be stacked horizontally in a stacking pattern of second container (lower tier), transport container (middle tier), first container (upper tier), and can also be stacked horizontally in a stacking pattern of first container (lower tier), transport container (middle tier), second container (upper tier).

[0013] The support legs of the first container are wide support legs that are wider than the support legs of the second container, and the upper end recess of the transport container has a first mounting portion on which a portion of the wide support legs of the first container is placed, and a second mounting portion that is formed between the first mounting portion and the pocket portion and is recessed in a stepped shape from the first mounting portion, and on which the support legs of the second container are placed.

[0014] The first placement portion has a protrusion that fits into a recess formed in the bottom surface of the wide support leg of the first container.

[0015] The support legs of the transport container are configured as L-shaped ribs when viewed from the bottom, with a first rib extending outward from the side wall portion connected to a second rib extending along the side wall portion, and when the transport container is stacked in the stacking direction on top of another transport container, the first container, or another container of the second container, the first rib rests on the upper surface or the upper end recess of the flange portion of the other container, and the second rib restricts horizontal movement of the transport container relative to the other container.

[0016] The transport container is rectangular in plan view and is characterized by having two long side support legs on the outer peripheral surface of the side wall portion on the long side, each having a pair of vertical ribs extending in the vertical direction and a horizontal rib connecting the lower ends of these vertical ribs.

[0017] Furthermore, one of the two long-side support legs has a protrusion protruding outward from the horizontal rib. The transport container has two long-side pockets on the inner peripheral surface of the side wall on the long side for accommodating the two long-side support legs, one of which has a pocket body and a recess that is recessed outward in a stepped shape from the pocket body, and when the one support leg is accommodated in the one long-side pocket, the protrusion is accommodated in the recess.

[0018] Furthermore, the transport container has two long side pockets on the inner surface of the side wall on the long side that accommodate the two long side support legs, and two short side pockets on the inner surface of the side wall on the short side, and each of the first container and the second container can be nested in the transport container, and when these are stacked in the nesting direction, each of the support legs of the first container and the support legs of the second container are accommodated in at least one of the long side pockets and the short side pockets.

[0019] The transport container is also characterized in that it can be nested with respect to the first container and the second container. The fact that the transport container can be nested with respect to the first container and the second container means that the transport container can be stacked horizontally with respect to the first container whether it is on top or bottom, and can be stacked horizontally with respect to the second container whether it is on top or bottom. [Effects of the Invention]

[0020] Because the transport container of the present invention has the above configuration, when a first container or a second container is stacked on top of the transport container in the stacking direction, the support legs of the first container or the support legs of the second container are placed on the upper recessed part of the transport container, and when the transport container is stacked on top of the first container or the second container in the stacking direction, the support legs of the transport container are placed on the upper recessed part of the first container or the upper recessed part of the second container, allowing the containers to be stably stacked horizontally. Therefore, even when different types of containers that cannot be stacked on top of each other are mixed, for example, by interposing the transport container as an intermediate container between them, these containers can be made stackable and a decrease in work efficiency can be suppressed.

[0021] In addition, the support legs of the first container are wide support legs that are wider than the support legs of the second container, and the upper end recess of the transport container has the first mounting portion and the second mounting portion, so that the support legs of the first container and the support legs of the second container, which have different widths, can be stably mounted while keeping the width of the upper end recess provided adjacent to the pocket portion small.

[0022] The first mounting portion has a convex portion that fits into a concave portion formed on the bottom surface of the wide support leg of the first container, thereby preventing horizontal shifting of the first container (such as rattling due to clearance or leaning to one side; the same applies below) when the first container is stacked in the stacking direction on top of the transport container, contributing to stable stacking.

[0023] The support legs of the transport container are composed of L-shaped ribs when viewed from the bottom. When the transport container is stacked on top of another container in the stacking direction, the first rib rests on the upper recess of the other container, and the second rib restricts the horizontal movement of the transport container relative to the other container, thereby preventing horizontal displacement of the transport container and contributing to stable stacking.

[0024] The transport container has two long side support legs on the outer peripheral surface of the side wall on the long side, each of which has a pair of vertical ribs extending in the vertical direction and a horizontal rib connecting the lower ends of these vertical ribs, and one of the support legs has a protrusion that protrudes outward from the horizontal rib.This prevents the transport container from shifting horizontally (especially in the short side direction) when stacked on top of another container in the stacking direction, contributing to stable stacking.

[0026] The transport container of the present invention is a transport container that can accommodate and transport or store products, etc., and is used at distribution sites. The transport containers are also structured to be nestable and stackable with each other and with other types of containers.

[0027] The structure of the transport container of the present invention will be explained below, and then its relationship with other containers will be explained.

[0028] (Regarding one embodiment of the transport container of the present invention) FIG. 1 shows a perspective view of one embodiment of a transport container of the present invention, and FIG. 2 shows a plan view. As shown in FIGS. 1 and 2, container 1 has a square shape with an open top and is rectangular in plan view. Container 1 is integrally molded from a synthetic resin such as polypropylene resin. In the present invention, the height direction of container 1 is referred to as the up-down direction, the direction parallel to the long side in a plan view of container 1 viewed from above in the up-down direction is referred to as the long side direction, and the direction parallel to the short side in that plan view is referred to as the short side direction.

[0029] Container 1 has a bottom surface 2 and four side walls that rise integrally from the periphery of bottom surface 2. The rectangular parallelepiped space surrounded by the four side walls forms a storage space for storing products and the like. The side walls are made up of a pair of side walls 3a, 3b on the short sides and a pair of side walls 3c, 3d on the long sides. Side walls 3a to 3d are inclined so as to widen gently outward toward the opening edge, and have flanges 4 at the opening edge.

[0030] The side walls 3a to 3d are formed with a large number of openings for cleaning, ensuring ventilation, and reducing weight, and in Fig. 1, two oval openings are formed in upper and lower rows. The bottom surface 2 is entirely formed in a mesh pattern, and has a large number of openings.

[0031] The flange portion 4 is formed to protrude outward. The flange portion 4 has a flange portion on a short side and a flange portion on a long side, which are connected at the four corners to form a rectangular frame. As shown in FIG. 1, the flange portion on the long side has a rail groove 41 that is slightly recessed from the upper end and extends in the long side direction. One end of the rail groove 41 opens into the pocket portion 6c, and the other end extends outward in the long side direction beyond the pocket portion 6d.

[0032] 1, container 1 has support legs 5a, 5b, 5c, and 5d that protrude outward from the outer peripheral surfaces of sidewalls 3a, 3b, 3c, and 3d, pockets 6a, 6b, 6c, and 6d formed on the inner peripheral surfaces of sidewalls 3a, 3b, 3c, and 3d, and upper recesses 7a and 7b that are recessed from the upper end into the inner edges of the flanges on the short sides. Each of pockets 6a, 6b, 6c, and 6d and upper recesses 7a and 7b opens upward to flange 4 and inward to the storage space.

[0033] Support legs 5a and 5b are formed on one side wall 3a of the short side of container 1 at the lower portion near both sides of the outer periphery. In FIG. 1, support legs 5a and 5b are rib-shaped support legs and are symmetrical to each other with respect to center line C1 (see FIG. 2) on the short side. Pockets 6a and 6b capable of accommodating support legs 5a and 5b are formed on the inner periphery of side wall 3b of the other short side in plan view, at positions point-symmetrical to support legs 5a and 5b around center point O (see FIG. 2) of container 1. When containers are stacked in the nesting direction, support legs 5a of another container 1 rotated 180° horizontally relative to container 1 overlap pockets 6a of side wall 3b, and support legs 5b of another container 1 overlap pockets 6b of side wall 3b.

[0034] Additionally, support legs (not shown) are formed on the other side wall 3b on the short side at the bottom near both sides of the outer periphery. Pockets 6a, 6b capable of accommodating the support legs are formed on the inner periphery of side wall 3a at positions point-symmetrical to the support legs, centered on the center point O (see FIG. 2) of container 1 in a plan view. When stacked in the nesting direction, one support leg of another container 1 rotated 180° horizontally relative to container 1 overlaps with pocket 6a of side wall 3a, and the other support leg of the other container 1 overlaps with pocket 6b of side wall 3a.

[0035] FIG. 3(a) shows an enlarged side perspective view of one of the support legs 5a formed on the side wall portion 3a. As shown in FIG. 3(a), the support leg 5a is connected to a first rib 51 extending outward (outward in the long side direction) from the side wall portion 3a and a second rib 52 extending along the wall surface of the side wall portion 3a. The second rib 52 protrudes less from the side wall portion 3a in the long side direction than the first rib 51. As shown in FIG. 3(b), the support leg 5a is configured as an L-shaped rib when viewed from the bottom. As will be described later, the support leg 5a is shaped to prevent horizontal misalignment when stacked while avoiding interference with the structure of the upper recesses of other containers.

[0036] In addition, in the support leg 5a, a stacking restriction rib 51a having a width smaller than that of the first rib 51 is integrally provided on the bottom surface of the first rib 51. The stacking restriction rib 51a extends outward (outward in the long side direction) from the side wall portion 3a and abuts against the wall surface of the pocket portion of the lower container or the convex portion of the upper end recess, thereby restricting the horizontal movement of the upper container. In FIG. 1, the stacking restriction rib 51a is formed closer to the inside in the short side direction of the first rib 51, and the inside end face of the short side direction of the first rib 51 and the inside end face of the stacking restriction rib 51a are flush with each other. The stacking restriction rib 51a may have the same width as the first rib 51, or the restriction rib 51a may be structurally indistinguishable from the first rib 51. In addition, the bottom surface of the second rib 52 is formed with a bottom surface recess 52a that is partially recessed from the bottom surface, which makes it easier to avoid interference with the structure of the upper end recess of other containers.

[0037] Returning to FIG. 1, support legs 5c and 5d are formed on one side wall 3c on one long side of container 1 at the bottom near both sides of the outer periphery. In FIG. 1, support legs 5c and 5d have different structures. Pockets 6c and 6d capable of accommodating support legs 5c and 5d are formed on the inner periphery of the other side wall 3d on the long side, at positions point-symmetrical to support legs 5c and 5d around center point O (see FIG. 2) of container 1 in plan view. When containers are stacked in the nesting direction, support leg 5c of another container 1 rotated 180° horizontally relative to container 1 overlaps pocket 6c of side wall 3d, and support leg 5d of another container 1 overlaps pocket 6d of side wall 3d.

[0038] Additionally, support legs (not shown) are formed on the other side wall 3d on the long side at the bottom near both sides of the outer periphery. Pockets 6c, 6d capable of accommodating the support legs are formed on the inner periphery of side wall 3c at positions point-symmetrical to the support legs, centered on the center point O (see FIG. 2) of container 1 in a plan view. When stacked in the nesting direction, one support leg of another container 1 rotated 180° horizontally relative to container 1 overlaps with pocket 6c of side wall 3c, and the other support leg of the other container 1 overlaps with pocket 6d of side wall 3c.

[0039] Figure 4(a) shows an enlarged side perspective view of the support leg 5c. The support leg 5c has a pair of vertical ribs 53, 53 protruding from the side wall portion 3c and extending in the vertical direction, and a horizontal rib 54 protruding from the side wall portion 3c and connecting the lower ends of the vertical ribs 53, 53 horizontally. The support leg 5c is formed in an upward U-shape. The lower end surface of the support leg 5c (i.e., the lower end surface of the horizontal rib 54) serves as the support surface when stacking another container on top of it in the stacking direction.

[0040] FIG. 4(b) shows an enlarged side perspective view of the support leg 5d. The support leg 5d has a pair of vertical ribs 55, 55 protruding from the side wall portion 3c and extending in the up-down direction, and a horizontal rib 56 protruding from the side wall portion 3c and connecting the lower ends of the vertical ribs 55, 55 horizontally. Furthermore, the support leg 5d has a protrusion 57a ​​protruding outward (outward in the short-side direction) from the horizontal rib 56. In FIG. 4(b), the protrusion 57a ​​is provided in the widthwise center of the horizontal rib 56 and is formed in a rib shape. Specifically, the protrusion 57a ​​forms part of an intermediate rib 57 extending in the up-down direction between the pair of vertical ribs 55, 55, and the lower part of the intermediate rib 57 is formed by partially protruding outward. Note that the position and shape of the protrusion are not limited to those shown in FIG. 4(b). For example, the protrusion does not have to be formed in the widthwise center of the horizontal rib 56, but may be formed toward one side (including the end) of the horizontal rib 56 in the extension direction. Alternatively, the intermediate rib may not be provided and only the protrusion may be formed partially.

[0041] As shown in Fig. 4, support legs 5c and 5d have different widths (lengths in the long side direction), with width W1 of support leg 5c being wider than width of support leg 5d. Furthermore, support legs 5c and 5d have different amounts of protrusion of the vertical ribs and horizontal ribs from side wall portion 3c (thickness of the support legs), with support leg 5c being thicker than support leg 5d. Due to these structural differences between support legs 5c and 5d, the structures of the corresponding pockets are also different.

[0042] 1, the pocket 6c that accommodates the support leg 5c is formed as a recessed space recessed from the upper end of the flange 4, and the thickness of the pocket 6c (the amount of recession from the inner peripheral surface of the side wall 3d outward in the short side direction) is formed to correspond to the thickness of the support leg 5c so as to be greater than the thickness of the pocket body of the pocket 6d (the amount of recession from the inner peripheral surface of the side wall 3d outward in the short side direction). Also, an inclined surface is formed on the inner wall surface in the long side direction that defines the pocket 6c so that the pocket opening widens toward the upper end.

[0043] Next, an enlarged view of pocket portion 6d that accommodates support leg 5d is shown in Fig. 5. As shown in Fig. 5, pocket portion 6d is formed to open into rail groove 41. Rail groove 41 functions as a rail when another container slides on container 1. Furthermore, when another container is stacked in the stacking direction, depending on the shape of the other container, this also serves as a portion on which the support leg of the other container is placed.

[0044] As shown in FIG. 5 , the pocket portion 6d is formed as a recessed space recessed from the bottom surface of the rail groove 41 and includes a pocket main body 61 and a recessed portion 62 recessed outward from the pocket main body 61. The pocket main body 61 is a recessed space surrounded by a pair of wall surfaces facing each other along the long side, a bottom surface, and an outer wall surface 61b facing the storage space. Of the pair of wall surfaces facing each other along the long side, the upper portion of the inner wall surface has an inclined surface 61a that slopes so that the opening widens toward the upper end. By forming this inclined surface 61a, when another container 1 is slid from the direction of arrow A to nest, for example, the support legs 5d of the container 1 are easily guided into the pocket portion 6d. Furthermore, when removing another container 1 from the nested state, the support legs 5d of the container 1 are easily guided, making it easy to insert and remove the other container 1.

[0045] In the pocket 6d, the recess 62 is recessed in a stepped manner from the outer wall surface 61b of the pocket main body 61 outward in the short side direction, and is formed as a rectangular parallelepiped recessed space that communicates with the pocket main body 61. The pocket depth in the vertical direction of the recess 62 is smaller than the pocket depth of the pocket main body 61. In addition, the opening width (length in the long side direction) W2 of the recess 62 is smaller than the opening width (length in the long side direction) of the pocket main body 61. When the support leg 5d is stored in the pocket 6d, the vertical ribs 55 and horizontal ribs 56 of the support leg 5d are stored in the pocket main body 61, and the protrusion 57a ​​is stored in the recess 62. The pocket depth in the vertical direction of the recess 62 may be the same as that of the pocket main body 61.

[0046] Here, the opening width W2 of the recessed portion 62 is set smaller than the width W1 of the support leg 5c (see FIG. 4(a)). As a result, when another container 1 is slid from the direction of arrow A to be stacked in the stacking direction, for example, the support leg 5c of the other container 1 can slide smoothly to the portion B where the support leg 5c is placed without falling into the pocket portion 6d.

[0047] Returning to FIG. 1, upper recesses 7a and 7b are formed on the inner edge of the flange on the short side of the container 1, recessed from the upper end. In the flange of the side wall 3a, upper recesses 7a and 7b are formed adjacent to the pockets 6a and 6b, respectively, on the outer side in the short side direction (outside-outside). These upper recesses 7a and 7b are not formed along the inner edges of the four corners. In the flange of the side wall 3b, upper recesses 7a and 7b are formed adjacent to the pockets 6a and 6b, respectively, on the inner side in the short side direction (inside-inside). The pockets 6a and the upper recesses 7a form a recessed space recessed from the upper end of the flange 4, with the top of the pocket 6a opening to the bottom of the upper recesses 7a. The relationship between the pockets 6b and the upper recesses 7b is similar.

[0048] Figure 6 shows an enlarged perspective view of the pocket 6a and upper recess 7a of the side wall 3a. As shown in Figure 6, the pocket 6a is formed to extend in the vertical direction and is formed as a rectangular parallelepiped recessed space. The upper recess 7a is a portion on which the support legs of other containers (such as the container 1 and a first container and a second container described below) to be stacked on top of the container 1 in the stacking direction are placed. This portion, recessed from the upper end of the flange 4, allows the support legs of the other container to fit into, allowing the other container to be placed stably.

[0049] The upper recess 7a has a structural configuration in which the support legs of the container stacked on top of the container 1 are placed depending on the shape of the support legs. Specifically, the upper recess 7a has a first placement portion 71 on which the support legs of the first container (described later) are placed, and a second placement portion 72 on which the support legs of the container 1 and the support legs of the second container (described later) are placed. The second placement portion 72 is formed between the first placement portion 71 and the pocket 6a and is recessed in a stepped shape from the first placement portion 71. In the side wall 3a shown in FIG. 6, the first placement portion 71, the second placement portion 72, and the pocket 6a are arranged side by side from the outside in the short side direction. On the other hand, in the side wall 3b (see FIG. 1), the pocket 6a, the second placement portion, and the first placement portion are arranged side by side from the outside in the short side direction.

[0050] As shown in FIG. 6, the first mounting portion 71 has a protrusion 73 protruding upward from its flat bottom surface. In FIG. 6, the protrusion 73 is formed on the inner edge of the first mounting portion 71 so as to be adjacent to the second mounting portion 72, but the position of the protrusion 73 is not limited to this. The protrusion 73 is a protrusion that fits into a recess formed in the bottom surface of a support leg of the first container (described later), for example, and its shape is not limited to a rectangular parallelepiped, as long as it is a shape that allows for fitting. Note that the protrusion 73 may be omitted, and the entire first mounting portion 71 may be formed as a flat surface. As shown in FIG. 6, the bottom surface of the second mounting portion 72 is formed at a lower position than the bottom surface of the first mounting portion 71, and the bottom surface of the pocket portion 6a is formed at an even lower position.

[0051] As shown in FIG. 6, the second placement portion 72 may have an inclined surface 74 formed on the outer side in the long side direction, which is connected to the flat bottom surface and has an opening that widens toward the upper end.

[0052] As described above, the container 1 has a plurality of support legs, a plurality of pockets, and a plurality of upper recesses. The container 1 has a shape that is line-symmetrical with respect to the center line C1 (see FIG. 2) of the short side, and a shape that is asymmetrical with respect to the center line C2 (see FIG. 2) of the long side.

[0053] When such containers 1 are stacked in the stacking direction, i.e., when the side walls 3a, 3b, 3c, and 3d of the upper and lower containers 1 are positioned in the same position in a plan view, they are stacked as shown in Figure 7. In Figure 7, the containers 1 are color-coded in two colors to make it easier to check their orientation. In this case, two containers 1 color-coded in two colors are stacked one on top of the other in the same color and shape, i.e., in the same orientation. In this state, the support legs 5a and 5b on the short sides of the upper container 1 are placed on the upper recesses 7a and 7b of the lower container 1, respectively. Furthermore, the support legs 5c and 5d on the long sides of the upper container 1 are placed on the upper surfaces of both rail grooves 41 of the flange portion 4 of the lower container 1, respectively.

[0054] FIG. 8 is a partial enlarged view of FIG. 7. As shown in FIG. 8, the first rib 51 of the rib-shaped support leg 5a of the upper container 1 is placed on the second mounting portion 72 of the upper recess 7a of the lower container 1. The second rib 52 is positioned so as not to interfere with the protrusion 73 formed on the first mounting portion of the upper recess 7a, and fills the gap between the protrusion 73 and the side wall 3a of the upper container 1, thereby preventing the upper container 1 from shifting in the longitudinal direction relative to the lower container 1. The shape of the support leg 5a is not limited to the shape shown in FIG. 8 and other figures. In FIG. 8, the second rib 52 of the support leg 5a is formed in a rib shape extending along the wall surface of the side wall 3a. However, it may be formed in a block shape that covers the upper surface of the protrusion 73, for example. This block-shaped portion may have a cavity formed toward the bottom surface or the like so as not to interfere with the protrusion 73. This block piece-shaped portion may be formed so as to protrude outward in the short side direction from the side surface of the first rib 51, or may be formed so as to protrude outward in the long side direction from the wall surface of the side wall portion 3a.

[0055] Furthermore, in the support legs 5d on the long side of the upper container 1, the protrusions 57a fill the gap between the horizontal ribs 56 and the inner wall surfaces (step portions) of the rail grooves 41, thereby preventing the upper container 1 from shifting in the short side direction relative to the lower container 1. Furthermore, the protrusions 57a make it easier to ensure a sufficient support margin for the lower container 1, making it easier to maintain a stable stacked state.

[0056] On the other hand, if the container 1 located on the upper level in the state shown in Figure 7 is rotated horizontally by 180 degrees (to give it a different color or shape), that is, if it is stacked in the nesting direction, the support legs 5a, 5b, 5c, and 5d of the upper container 1 will overlap with each pocket portion of the lower container 1, resulting in a nested state and making the two stacked containers 1 lower in volume.

[0057] (For other types of containers) The transport container of the present invention described above has a structure that allows it to be stacked with other types of containers that have a different shape from the transport container. A different shape from the transport container means that the shape and position of the support legs are different, and that the presence or absence of a recessed top end, or the shape and position of the recessed top end, are different. The term "other types of containers" used here refers to containers that have roughly the same external dimensions (width (length in the long side direction) x depth (length in the short side direction)) as the transport container (specifically, the difference in each dimension is within 10 mm). Examples of first and second containers as other types of containers are described using Figures 9 and 10. Note that first containers can be nested and stacked with other first containers. Also, second containers can be nested and stacked with other second containers.

[0058] As shown in Figure 9, the first container 11 is rectangular with an open top, has a bottom portion 12, and four side wall portions 13a, 13b, 13c, and 13d that rise integrally from the peripheral edge of the bottom portion 12, and has a flange portion 14 at the open end.

[0059] Support legs 15a and 15b are formed on one side wall 13a on the short side of the container 11 at the lower portion near both sides of the outer periphery. Each support leg 15a and 15b has a pair of vertical ribs extending vertically and a horizontal rib connecting the lower ends of the vertical ribs horizontally. A rectangular recess is formed on the bottom surface of each support leg 15a and 15b (the bottom surface of the horizontal rib) in a bottom view. Pockets 16a and 16b capable of accommodating the support legs 15a and 15b are formed on the inner periphery of the other side wall 13b on the short side, at positions point-symmetrical to the support legs 15a and 15b with respect to the center point of the container 11 in a plan view. Support legs are also formed on the other side wall 13b on the short side, and pockets 16a and 16b capable of accommodating the support legs are formed on the inner periphery of the side wall 13a.

[0060] Additionally, upper recesses 17a, 17b are formed on the inner edge of the flange 14 on the short side of the container 11, recessed from the top end. Upper recesses 17a, 17b are formed on the flange of the side wall 13a, adjacent to the pockets 16a, 16b, respectively, on the outer side in the short side direction. Upper recesses 17a, 17b are formed on the flange of the side wall 13b, adjacent to the pockets 16a, 16b, respectively, on the inner side in the short side direction. The upper recesses 17a, 17b are the portions on which the support legs 15a, 15b of the container 11 are placed when the container 11 is stacked with another container 11 in the stacking direction. The upper recesses 17a, 17b have protrusions that fit into the recesses in the bottom surfaces of the support legs 15a, 15b.

[0061] Note that no support legs or pockets are formed on the side walls 13c and 13d on the long sides of the container 11. The flanges on the long sides are formed as flat surfaces, and do not have rail grooves that are slightly recessed from the upper ends and extend in the long side direction.

[0062] The first container may be, for example, a container conforming to the food crate standard established by the Logistics Crate Standardization Council. More specifically, a Type II shallow container conforming to this standard may be used. The outer dimensions of this Type II shallow container are 557 mm wide (long side length) x 459 mm deep (short side length) x 108 mm high, with inner dimensions of 509 mm x 419 mm x 98 mm, and effective inner dimensions of 490 mm x 400 mm x 86 mm.

[0063] 10, the second container 21 has a rectangular shape with an open top, a bottom surface 22, and four side walls 23a, 23b, 23c, and 23d that rise integrally from the periphery of the bottom surface 22, and a flange 24 at the open end. The flange on the long side has a rail groove 24a that is slightly recessed from the upper end and extends in the long side direction. One end of the rail groove 24a opens into the pocket 26c, and the other end extends outward in the long side direction beyond the pocket 26d.

[0064] Support legs 25a, 25b are formed on one side wall 23a on the short side of container 21 at the lower part near both sides of the outer circumferential surface. Each of support legs 25a, 25b is a rib-shaped support leg. Pockets 26a, 26b capable of accommodating support legs 25a, 25b are formed on the inner circumferential surface of side wall 23b on the other short side at positions point-symmetrical to support legs 25a, 25b about the center point of container 21 in a plan view. Support legs are also formed on the other side wall 23b on the short side, and pockets 26a, 26b capable of accommodating these support legs are formed on the inner circumferential surface of side wall 23a.

[0065] Support legs 25c, 25d are formed on one side wall portion 23c on the long side of container 21 at the lower portion near both sides of the outer circumferential surface. Support legs 25c, 25d differ from each other in both the amount of protrusion (thickness of the support legs) and width (length in the long side direction). Pockets 26c, 26d capable of accommodating support legs 25c, 25d are formed on the inner circumferential surface of side wall portion 23d on the other long side at positions point-symmetrical to support legs 25c, 25d around the center point of container 21 in a plan view. Support legs are also formed on the other side wall portion 23d on the long side, and pockets 26c, 26d capable of accommodating these support legs are formed on the inner circumferential surface of side wall portion 23c.

[0066] Pockets 26c and 26d are formed as recessed spaces recessed from the bottom surface of rail groove 24a and have a pocket body. The pocket body is a recessed space surrounded by a pair of wall surfaces facing each other in the long side direction, a bottom surface, and an outer wall surface facing the storage space. Of the pair of wall surfaces facing each other in the long side direction, the upper part of the inner wall surface has an inclined surface that is inclined so that the opening widens toward the upper end. By forming this inclined surface, when another container 21 is slid and nested, the support legs of the container 21 can be more easily guided into pockets 26c and 26d.

[0067] The inner edge of the flange portion 24 on the short side of the container 21 is recessed from the upper end to form upper end recesses 27a, 27b. The flange portion of the side wall portion 23a is formed with upper end recesses 27a, 27b on the outer side in the short side direction, adjacent to the pocket portions 26a, 26b, respectively. The flange portion of the side wall portion 23b is formed with upper end recesses 27a, 27b on the inner side in the short side direction, adjacent to the pocket portions 26a, 26b, respectively. The upper end recesses 27a, 27b are portions on which the support legs 25a, 25b of the container 21 are placed when another container 21 is stacked in the stacking direction, and the upper end recesses 27a, 27b are formed as flat surfaces. The upper end recesses 27a, 27b do not have protrusions like the upper end recesses 17a, 17b.

[0068] Here, a schematic diagram of the state in which the above-mentioned containers 11 and 21 are stacked is shown in Figure 11. Specifically, containers 11 and 21 are stacked so that the short sides and long sides are facing the same direction, and the positional relationship between the support legs and the pockets on the short sides is the same up and down. Figure 11 shows a schematic diagram as seen from the side walls 13a and 23a on the short sides (regarding the positional relationship between the support legs and the pockets, the support legs are positioned outside-outside of the pockets on both containers).

[0069] FIG. 11(a) shows a case where the container 11 is placed on the upper level and the container 21 is placed on the lower level, and FIG. 11(b) shows a case where the container 21 is placed on the upper level and the container 11 is placed on the lower level.

[0070] In the case of stacking as shown in FIG. 11(a), the support legs 15a, 15b of the upper container 11 cannot be fully fitted into the upper recesses 27a, 27b of the lower container 21, making stacking impossible. In this case, the upper container 11 cannot be stably placed due to tilting relative to the lower container 21. In the case of stacking as shown in FIG. 11(b), the support legs 25a, 25b of the upper container 21 are formed with narrow ribs, but the upper recesses 17a, 17b of the lower container 11 have protrusions. Therefore, the support legs 25a, 25b interfere with the protrusions or fall into the pockets 16a, 16b, making it impossible to fit into the upper recesses 17a, 17b, making stacking impossible. In this case, the upper container 21 cannot be stably placed due to tilting relative to the lower container 11. Thus, the containers 11 and 12 cannot be stacked with each other.

[0071] (Regarding the relationship with other types of containers) In contrast, the above-described transport container of the present invention is stackable with respect to each of container 11 and container 21. The external dimensions of the transport container of the present invention, container 11, and container 21 are, for example, approximately 560 mm in the long side length and approximately 460 mm in the short side length.

[0072] 12 is a schematic diagram showing a state in which the container 1 of the present invention is stacked in the stacking direction between a second container 21 (lower level) and a first container 11 (upper level). Specifically, the containers are stacked so that the side wall 3a of the container 1 is positioned at the same position as the side wall 13a of the container 11 and the side wall 23a of the container 21 in a plan view. The same is true for FIG. 14.

[0073] As shown in FIG. 12, the upper recesses 7a and 7b of the container 1 are formed so that the support legs 15a and 15b of the first container 11 can be placed thereon. The support legs 15a and 15b of the first container 11 are wider than the support legs 25a and 25b of the second container 21, and have recesses 151 formed in their bottom surfaces. In the upper recess 7a, a portion of the support leg 15a of the first container 11 is placed on the first mounting portion 71. At this time, the remaining portion of the support leg 15a faces the second mounting portion 72 via a gap. The convex portion of the first mounting portion 71 fits into the recess 151 of the support leg 15a. In this way, the upper recess 7a can receive the entire support leg 15a, while only a portion of it (the first mounting portion 71) is placed thereon. This allows the width of the upper recess 7a to be kept small while still accommodating the support legs of different containers.

[0074] On the other hand, the support legs 5a, 5b of the container 1 are formed to be placed on the upper end recesses 27a, 27b of the second container 21. In this case, the first rib 51 of the support leg 5a is placed on the upper end recess 27a, and the second rib 52 is not placed thereon.

[0075] The state in which the containers are stacked in this manner in the stacking direction is shown in Figure 13. As shown in Figure 13, support legs 5a and 5b on the short sides of container 1 are placed on upper recesses 27a and 27b, respectively, of container 21 in the lower tier, and support legs 5c and 5d on the long sides of container 1 are placed on the upper surfaces of both rail grooves 24a in flange portion 24 of container 21. In addition, support legs 15a and 15b on the short sides of container 11 are placed on upper recesses 7a and 7b, respectively, of container 1 in the lower tier.

[0076] Next, FIG. 14 is a schematic diagram showing the stacking of the container 1 of the present invention between a first container 11 (lower tier) and a second container 21 (upper tier) in the stacking direction. As shown in FIG. 14, the upper recesses 7a and 7b of the container 1 are formed so that the support legs 25a and 25b of the second container 21 can be placed thereon. In the upper recess 7a, the ribbed support leg 25a of the second container 21 is placed on the second placement portion 72. The support legs 5a and 5b of the container 1 are also formed so that they can be placed in the upper recesses 17a and 17b of the first container 11, and the first rib 51 of the support leg 5a is placed in the upper recess 17a. More specifically, the first rib 51 of the support leg 5a of the container 1 is placed in a portion inward in the short side direction from the protrusions formed in the upper recesses 17a and 17b. On the opposite short side, the positional relationship of the support leg relative to the pocket portion is reversed (inside-inside), and the first rib of the support leg of container 1 is placed on the outer side of the short side than the convex portion formed in the upper end recess of first container 11.

[0077] In addition, the second rib 52 of the support leg 5a is not placed on the upper end recess 17a, but is positioned so as not to interfere with the protrusion 171 formed in the upper end recess 17a, and by filling the gap between the protrusion 171 and the side wall portion 3a of the upper container 1, it is possible to prevent the upper container 1 from shifting in the long side direction relative to the lower first container 11.

[0078] The state in which the containers are stacked in this manner in the stacking direction is shown in Figure 15. As shown in Figure 15, support legs 5a and 5b on the short sides of container 1 are placed on upper recesses 17a and 17b of the lower container 11, respectively, and support legs 5c and 5d on the long sides of container 1 are placed on the upper surface of flange portion 4 of container 11, respectively. In addition, support legs 25a and 25b on the short sides of container 21 are placed on upper recesses 7a and 7b of the lower container 1, respectively.

[0079] 12 and 14, when three types of containers are stacked, for example, on the short side wall, the other support legs (support legs 5a and 25a, support legs 5b and 25b in FIG. 12) are located within the width of the widest support leg (support legs 15a and 15b in FIG. 12). Also, within the width of the widest upper recess (upper recesses 7a and 7b in FIG. 12), at least a portion of the other upper recesses (upper recesses 17a and 27a, top recesses 17b and 27b in FIG. 12) are located in positions that overlap in the vertical direction.

[0080] In this way, the transport container (container 1) of the present invention can make these containers stackable even when mixed with other types of containers (first container 11 and second container 21) that cannot be stacked with each other, for example, by using the container as an intermediate container between them.

[0081] Furthermore, the transport container of the present invention can of course be used not only at distribution sites where three types of containers (including the transport container itself) are distributed, but also at distribution sites where only the transport container itself is distributed, or at distribution sites where two types of containers are distributed: the transport container itself and one other type (the above-mentioned first container or second container).

[0082] (Regarding other embodiments of the transport container of the present invention) FIG. 16 shows a perspective view of another embodiment of the transport container of the present invention. As shown in FIG. 16, container 1A has a bottom surface 2 and four side walls (a pair of side walls 3a, 3b on the short sides and a pair of side walls 3c, 3d on the long sides) that rise integrally from the peripheral edge of bottom surface 2. Container 1A also has support legs 5a, 5b, 5c, and 5d' that extend outward from the outer periphery of side walls 3a, 3b, 3c, and 3d, pockets 6a, 6b, 6c, and 6d' formed on the inner periphery of side walls 3a, 3b, 3c, and 3d, and upper recesses 7a and 7b that are recessed from the upper end into the inner edge of the flange on the short side. Container 1A is generally similar in configuration to container 1 (see FIG. 1) described above, but differs in the configuration of support legs 5d' and pockets 6d'. The following description will focus on these features.

[0083] Support legs 5c, 5d' are formed on one side wall 3c of the long side of the container 1A at the lower portion near both sides of the outer periphery. In the container 1 (see FIG. 1), the support leg 5d had a protrusion 57a ​​(see FIG. 4) protruding outward (outward in the short side direction) from the horizontal rib, but the support leg 5d' of the container 1A does not have such a protrusion. Specifically, the support leg 5d' has a pair of vertical ribs 55, 55 protruding from the side wall 3c and extending in the vertical direction, and a horizontal rib 56 protruding from the side wall 3c and connecting the lower ends of the vertical ribs 55, 55 horizontally, and is formed in an upwardly U-shape. In other words, the support leg 5d' has a configuration in which the protrusion 57a, including the intermediate rib 57, is omitted from the support leg 5d described above. The width of the support leg 5c is wider than the width of the support leg 5d'. The thickness of the support leg 5c is thicker than the thickness of the support leg 5d'.

[0084] As described above, the formation of protrusions 57a has the advantage of preventing horizontal misalignment and ensuring a support margin. However, when considering nesting the container with other types of containers, the protrusions protrude outward, and may interfere with the pockets of the other types of containers (for example, pockets 26d of container 21). Taking this into consideration, the support legs of container 1A are configured without protrusions.

[0085] 16, a pocket 6d' capable of accommodating the support leg 5d' is formed on the inner peripheral surface of the other side wall 3d on the long side of the container 1A in a plan view, at a position point-symmetrical to the support leg 5d' with respect to the center point of the container 1A. In the container 1 described above, the pocket 6d had a recess 62 (see FIG. 5) on the outer side from the pocket body for accommodating the protrusion, but the pocket 6d' of the container 1A does not have a recess. Specifically, the pocket 6d' is composed of a pocket body 61, which is a recessed space surrounded by a pair of wall surfaces opposing each other in the long side direction, a bottom surface, and an outer wall surface opposing the storage space. In other words, the pocket 6d' has a configuration in which the recess 62 is omitted from the pocket 6d described above.

[0086] Even if the pocket 6d' has a shape in which a recess is formed like the above-described pocket 6d, it is considered that the support legs 5d' of another container 1A can be stored in that pocket when stacked in the nesting direction. On the other hand, when considering stacking another type of container on the container in the nesting direction, the recess has an irregular shape and may interfere with the support legs of the other type of container. Taking this into consideration, the pocket of the container 1A is configured without a recess. Furthermore, the pocket 6d' has a shape corresponding to the support legs 5d'.

[0087] The containers 1A can be nested and stacked with each other. As shown in Fig. 17(a), an upper container 1A can be stacked on top of a lower container 1A in the stacking direction to form a stacked state. In this case, the support legs 5d' described above are placed on the upper surfaces of the rail grooves 41 in the flange portions of the lower container 1A.

[0088] 17(b), an upper container 1A can be stacked on top of a lower container 1A in the nesting direction to form a nested state. In this state, the upper container 1A is rotated 180° horizontally relative to the lower container 1A, and a portion of it is housed within the lower container 1A. Specifically, the support leg 5c of the upper container 1A is housed in the pocket 6c in the side wall 3d of the lower container 1A, and the support leg 5d' of the upper container 1A is housed in the pocket 6d' in the side wall 3d of the lower container 1A. Furthermore, the support leg 5a on the side wall 3a of the upper container 1A is housed in the pocket 6a in the side wall 3b of the lower container 1A, and the support leg 5b on the side wall 3a of the upper container 1A is housed in the pocket 6b in the side wall 3b of the lower container 1A. As a result, compared to the stacked state, the storage space for the lower container 1A is reduced in volume, and the height dimension in the stacked state is reduced.

[0089] The container 1A can be stacked with other types of containers. For example, FIG. 18(a) shows a perspective view of a stacked state in which a first container 11 is stacked on top of the container 1A in the stacking direction. The relationship between the support legs of the first container 11 and the mounting portion of the container 1A is the same as in FIG. 13. Although not shown, the container 1A can also be stacked on top of the first container 11. The same applies to the second container 21 (see FIG. 10).

[0090] Furthermore, container 1A can be nested with other types of containers. For example, Fig. 18(b) shows a perspective view of a nested state in which container 1A is stacked on top of container 21 in the nesting direction. In this state, container 1A and container 21 are stacked so that the short sides and long sides are facing the same direction, and the positional relationship between the support legs and the pocket portion on the short sides is different between the top and bottom (the support legs of one container are positioned outside-outside of the pocket portion, and the support legs of the other container are positioned inside-inside).

[0091] 18(b), the support leg 5c on the side wall 3c of the upper container 1A is housed in the pocket 26c on the side wall 23d of the lower container 21, and the support leg 5d' on the upper container 1A is housed in the pocket 26d on the side wall 23d of the lower container 21. Furthermore, the support leg 5a on the side wall 3a of the upper container 1A is housed in the pocket 26a on the side wall 23b of the lower container 21, and the support leg 5b on the side wall 3a of the upper container 1A is housed in the pocket 26b on the side wall 23b of the lower container 21.

[0092] Note that a container 21 can also be stacked on top of container 1A in the nesting direction to form a nested state. Specifically, support leg 25c on side wall 23c of upper container 21 is accommodated in pocket 6c on side wall 3d of lower container 1A, and support leg 25d on side wall 23c of upper container 21 is accommodated in pocket 6d on side wall 3d of lower container 1A. Furthermore, support leg 25a on side wall 23a of upper container 21 is accommodated in pocket 6a on side wall 3b of lower container 1A, and support leg 25b on side wall 23a of upper container 21 is accommodated in pocket 6b on side wall 3b of lower container 1A.

[0093] Furthermore, container 1A can be nested with first container 11 and stacked horizontally. In this case, the support legs of the upper container rest on the flange of the lower container, allowing the upper container to be stacked horizontally, forming what is referred to as a nesting relationship in the present invention. It is also possible to provide an upper recess in the flange so that the support legs can be placed there. In this way, the container of the present invention can be nested with respect to each of the first container and the second container.

[0094] The transport container of the present invention is not limited to the above-described configuration.

[0095] For example, in Figures 1 and 16 above, the containers 1 and 1A have support legs 5c and 5d on the long side wall portions 3c and 3d and pocket portions 6c and 6d, but the long side wall portions may not have support legs or pocket portions.

[0096] In the above example, the transport containers are divided into two colors. The containers are of the same shape and color, but they may be of different shapes and colors, stacking types. There are no particular limitations on the color division.

[0097] Furthermore, although the containers 1 and 1A have a rectangular planar shape in the above description, the present invention may also be applied to a transport container having a square planar shape.

[0098] The first and second containers used in combination with the transport container of the present invention are not limited to the above-described configurations. For example, the first and second containers shown in Figures 9 and 10 above are configured with an upper recess formed on the inner edge of the flange on the short side, but the transport container of the present invention can also be used in combination with first and second containers that do not have an upper recess. In this case, the support legs of the transport container of the present invention are placed on the upper surface of the flange of the first or second container configured in this way. [Industrial Applicability]

[0099] The transport container of the present invention can suppress a decrease in work efficiency even when different types of containers are mixed in, and can therefore be widely used in distribution sites. [Explanation of symbols]
