Description

[Technical Field]

[0001] The present disclosure relates to a container. [Background technology]

[0002] Patent Document 1 discloses a folding container in which side walls are rotatably connected to the outer edges of a rectangular bottom wall, and which can be switched between an assembled state in which the side walls stand up from the bottom wall, and a folded state in which the side walls are folded and stacked. This folding container consists of a bottom wall, a pair of first side walls rotatably connected to the outer edges of the short sides of the bottom wall, and a pair of second side walls rotatably connected to the outer edges of the long sides of the bottom wall.

[0003] A handle protrusion is formed on the outer surface of the first side wall. The handle protrusion is located near the top end, middle part, or bottom end of the first side wall in the up-down direction. The handle protrusion consists of a ceiling wall portion formed by raising a portion of the first side wall slightly higher than its surrounding area, a pair of side wall portions hanging down from both lateral ends of the ceiling wall portion, and a front wall hanging down from the leading edge of the ceiling wall portion and having both ends connected to the side wall portions, and is open on the bottom side.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-40462 Summary of the Invention [Problem to be solved by the invention]

[0005] In the above-mentioned folding container, the handle protrusion is formed at only one position in the vertical direction. Therefore, when the folding container is tilted in the longitudinal direction, there is a difference in height between the handle protrusion formed on one first side wall and the handle protrusion formed on the other first side wall, and the line connecting the two handle protrusions is not horizontal, making it difficult for a worker to lift the folding container in a tilted state. Furthermore, the above-mentioned folding container is long in the longitudinal direction, and the handle protrusion is formed at only one position in the lateral direction on each first side wall. Therefore, when two workers, one on each side in the longitudinal direction, each hold one handle protrusion, each worker has to hold one handle protrusion with one hand and the bottom wall with the other, making it difficult to lift the folding container.

[0006] The present disclosure has been made in consideration of the above reasons, and its purpose is to provide a container that allows a user to select the part of the container to hold in the vertical direction of the container, and that can be held in two places with both hands, each located separately in the horizontal direction of the container. [Means for solving the problem]

[0007] A container according to one aspect of the present disclosure has a rectangular bottom, a pair of first side walls rising from a pair of opposing sides of the bottom, and a pair of second side walls rising from another pair of opposing sides of the bottom, and is open upward. The container has a first lifting handle provided on an outer surface of the first side wall at a first vertical position and a second lifting handle provided at a second vertical position lower than the first vertical position. At least one of the first lifting handle and the second lifting handle is provided in plurality and spaced apart from each other in the horizontal direction. [Effects of the Invention]

[0008] A container according to one aspect of the present disclosure allows a user to select a portion of the container to hold in the vertical direction of the container, and also allows the user to hold the container in two places with both hands, each located apart in the horizontal direction of the container.

[0010] The present disclosure relates to containers, and more particularly to containers with handles.

[0011] (1) First embodiment As shown in FIG. 1, the container 1 of the first embodiment includes a container body 2 and a partition member (not shown) that can be installed in the container body 2.

[0012] (Container body) The container body 2 constitutes the main body of the container 1. The container body 2 has a bottom 20 and a plurality of side walls 21, 22. Specifically, the container body 2 has the plurality of side walls 21, 22, which are a pair of first side walls 21 that stand up from a pair of opposing sides of the rectangular bottom 20, and a pair of second side walls 22 that stand up from another pair of opposing sides of the bottom 20.

[0013] The container body 2 of the first embodiment is a foldable container for transportation that can be transformed between an assembled state and a folded state. When the container body 2 is in the assembled state, the side walls 21, 22 stand upright relative to the bottom 20. In this case, the container body 2 has a box-like shape that opens upward, and an inner region 23 surrounded by a pair of first side walls 21 and a pair of second side walls 22 is formed inside the container body 2. This inner region 23 is used as a storage space for storing items. When the container body 2 is in the folded state, the side walls 21, 22 are folded down and overlap the bottom 20, and the container body 2 has a generally plate-like shape.

[0014] In this disclosure, unless otherwise specified, the container 1 will be described when the container body 2 is in an assembled state as shown in Fig. 1. For convenience, directions will be defined in this disclosure as shown in Fig. 1. That is, with the center position of the container 1 as the reference, the direction toward the bottom 20 is defined as the downward direction, and the opposite direction is defined as the upward direction, and one direction parallel to the length direction of the rectangular bottom 20 is defined as the forward direction, and the opposite direction is defined as the backward direction. Furthermore, the left-right direction will be defined based on the view from the front to the rear.

[0015] The bottom 20 and the side walls 21, 22 of the container body 2 are each made of synthetic resin, for example, polypropylene. Note that the bottom 20 and the side walls 21, 22 may each be made of a synthetic resin other than polypropylene, or may each be made of a material other than synthetic resin.

[0016] The side walls 21, 22 are rotatably connected to the bottom 20. Specifically, the pair of first side walls 21 are rectangular (see FIG. 2) and are rotatably attached to a pair of opposing sides of the rectangular bottom 20. The pair of second side walls 22 are rectangular (see FIG. 3) and are rotatably attached to another pair of opposing sides of the rectangular bottom 20.

[0017] The container body 2 is not limited to a foldable container. The container body 2 may be, for example, a container in which the side walls 21, 22 are attached to the bottom 20 so as not to rotate. The container body 2 may also be an integrally molded product in which the side walls 21, 22 are formed integrally with the bottom 20.

[0018] The bottom portion 20 of the first embodiment is formed in a rectangular shape extending in one direction when viewed from above, and has a pair of opposing short sides and a pair of opposing long sides. The length of the long sides of the bottom portion 20 is approximately twice the length of the short sides. The bottom portion 20 has a plurality of raised portions 201, 202 protruding upward from the peripheral edge of the rectangular bottom portion 20.

[0019] The bottom portion 20 has a total of four raised portions, including a pair of second raised portions 202 and a pair of first raised portions 201. The pair of first raised portions 201 are formed on a pair of short sides of the rectangular bottom portion 20. The pair of second raised portions 202 are formed on a pair of opposing long sides of the rectangular bottom portion 20. Each of the raised portions 201, 202 protrudes upward from the bottom portion 20.

[0020] The lower ends of the pair of first side walls 21 are respectively connected to the pair of first upright portions 201 so as to be rotatable about a rotation axis parallel to the front-rear direction. The lower ends of the pair of second side walls 22 are respectively connected to the pair of second upright portions 202 so as to be rotatable about a rotation axis parallel to the left-right direction. In other words, the pair of first side walls 21 are respectively rotatably attached to a pair of short sides of the bottom portion 20, and the pair of second side walls 22 are respectively rotatably attached to a pair of long sides of the bottom portion 20. Note that each first side wall 21 may be rotatably attached to the long sides of the bottom portion 20, and each second side wall 22 may be rotatably attached to the short sides of the bottom portion 20.

[0021] The length of the long side of the bottom 20 does not have to be approximately twice the length of the short side, and the length ratio (length of the long side / length of the short side) may be, for example, 1.5 or more, 2 or more, 3 or more, etc., and is not particularly limited. In addition, the bottom 20 may be formed in a square shape when viewed from above.

[0022] The container body 2 can be transformed into an assembled state and a folded state by rotating each of the side walls 21, 22 relative to the bottom 20. The container 1 in the assembled state can be transformed into a folded state by rotating each of the first side walls 21 relative to the bottom 20 to tilt them onto the bottom 20, and then rotating each of the second side walls 22 relative to the bottom 20 to tilt the pair of second side walls 22 onto the pair of first side walls 21.

[0023] The container 1 in the folded state can be transformed into the assembled state by rotating each second side wall 22 relative to the bottom 20 to make it stand up, and then rotating each first side wall 21 relative to the bottom 20 to make it stand up.

[0024] When the container body 2 is in an assembled state, the upper ends of the second side walls 22 and the upper ends of the first side walls 21 are located at the same height. The length in the front-to-rear direction of each second side wall 22 is longer than the sum of the vertical length of one first side wall 21 and the vertical length of the other first side wall 21. Therefore, in the folded container body 2, the pair of first side walls 21 do not overlap each other vertically, and the middle portions of each second side wall 22 in the front-to-rear direction do not overlap the pair of first side walls 21 when viewed from above.

[0025] Each first side wall 21 has a pair of notches 210. The pair of notches 210 are formed at both end portions in the left-right direction of the first side wall 21. Each notch 210 penetrates the first side wall 21 in the front-rear direction.

[0026] Each second side wall 22 has a pair of fitting portions 220. The pair of fitting portions 220 is formed on both end portions of the second side wall 22 in the front-rear direction. Each fitting portion 220 is a protrusion formed on the inner surface of the second side wall 22, and protrudes from the second side wall 22 toward the corresponding first side wall 21 (inward in the left-right direction). When the container body 2 is in an assembled state, the pair of fitting portions 220 of each second side wall 22 fits into the corresponding notch 210 of the first side wall 21, closing off this notch 210.

[0027] As shown in Figure 2, the first side wall 21 has an engaging protrusion 211 in a portion that lies along the second side wall 22 in the assembled state, and the second side wall 22 has an opening 221 in which the engaging protrusion 211 fits in a portion that corresponds to the engaging protrusion 211 in the assembled state.

[0028] (locking member) The container 1 further includes a pair of locking members 3 provided on each of the pair of first side walls 21. Each locking member 3 is attached to the outer surface of the corresponding first side wall 21 so as to be movable in the up and down direction. Each locking member 3 is made of, for example, a synthetic resin. However, the material of each locking member 3 is not limited.

[0029] An upward force is applied to the locking member 3 by, for example, an elastic member such as a spring or rubber provided separately from the locking member 3 on the first side wall 21, or an elastic portion such as a leaf spring that is part of the locking member 3.

[0030] When the container 1 is transformed from the folded state to the assembled state, the locking members 3 provided on the first side walls 21 are caught on the second side walls 22 standing relative to the bottom 20. As a result, the first side walls 21 standing relative to the bottom 20 are locked and restricted from rotating relative to the bottom 20.

[0031] To release the locked state, the user simply moves the locking member 3 downward relative to the first side wall 21. This disengages the locking member 3 of the first side wall 21 from the corresponding second side wall 22, and each first side wall 21 enters an unlocked state in which rotation relative to the bottom 20 is not restricted.

[0032] (Partition member) The container 1 further includes a partition member. Any number of partition members can be installed in the container body 2 depending on the application, etc. The container 1 can also be used without installing any partition member in the container body 2.

[0033] Each partition member is formed in a shape that makes it difficult for the overall shape to deform, and when installed in the container body 2, the relative positions of both left and right ends placed on the mounting portion 24 of the container body 2 are unlikely to change.

[0034] Each partition member has rigidity and is difficult to deform, but it may also be a member that is easily deformed. Furthermore, the shape and size of each partition member are not limited. For example, each partition member is not limited to a plate shape, but may be a plane shape or a mesh shape with many holes. Furthermore, the shape and size of each partition member may differ from one partition member to another.

[0035] Each partition member is inserted into the inner region 23 of the container body 2, for example, through an opening 25 formed at the upper end of the container body 2, and then the ends on both sides of the left and right sides of the partition member are placed on a pair of mounting portions 24 formed on each of a pair of second side walls 22, and the partition member is installed in the container body 2.

[0036] (Lifting handle) 2, the container 1 has lifting handles. Specifically, a first lifting handle 41 and a second lifting handle 42 are formed on the container 1 as lifting handles. The first lifting handle 41 and the second lifting handle 42 are formed on the outer surface of the first side wall 21, are areas recessed toward the center of the container 1 from the surrounding areas, and have a ceiling surface that is supported by the worker's hand.

[0037] The first lifting handle 41 is provided at a first vertical position 51 on the outer surface of the first side wall 21. The first vertical position 51 refers to a range having a predetermined length in the vertical direction, and the predetermined length is the vertical length of the first lifting handle 41. In the first embodiment, the upper end of the first vertical position 51 is located slightly below the upper end of the first side wall 21, and the lower end of the first vertical position 51 is located slightly below the upper end of the first vertical position 51.

[0038] The second lifting handle 42 is provided at a second vertical position 52 on the outer surface of the first side wall 21. Like the first vertical position 51, the second vertical position 52 refers to a range having a predetermined length in the vertical direction, and the predetermined length is the vertical length of the second lifting handle 42. The second vertical position 52 is lower than the first vertical position 51. In the first embodiment, the upper end of the second vertical position 52 is located below the upper end of the first side wall 21 by about half the vertical length of the first side wall 21, and the lower end of the second vertical position 52 is located slightly below the upper end of the second vertical position 52.

[0039] The lifting handles are formed at two locations on the first side wall 21 in the vertical direction, a first vertical position 51 and a second vertical position 52. Therefore, when a worker stacks multiple containers 1, if the container 1 does not need to be lifted to a low height, the worker can lift the container 1 by holding the first lifting handle 41, and if the container 1 needs to be lifted to a higher height, the worker can lift the container 1 by holding the second lifting handle 42.

[0040] Furthermore, when lowering the uppermost container 1 among the stacked containers 1, lowering the container 1 by holding the second lifting handle 42 makes it easier to lower the container 1 than when lowering the container 1 by holding the first lifting handle 41.

[0041] When the container 1 is tilted in the longitudinal direction, i.e., when the container 1 is tilted so that the front end is higher and the rear end is lower, for example, at an angle as shown in FIG. 3 , the height of the second vertical position 52 of the front first side wall 21 and the height of the first vertical position 51 of the rear first side wall 21 are approximately the same. In this case, the line connecting the second lifting handle 42 formed on the front first side wall 21 and the first lifting handle 41 formed on the rear first side wall 21 is horizontal, and the worker can lift the container 1, for example, by holding the second lifting handle 42 formed on the front first side wall 21 with his left hand and the first lifting handle 41 formed on the rear first side wall 21 with his right hand. This makes it easier for the worker to lift the container 1 naturally in a physically symmetrical state, in other words, without being conscious of the difference between the left and right sides even if the container is not strictly symmetrical. In addition, when stacking, the upper end of the bottom 20 of the upper container 1 inclined in the longitudinal direction is placed on the upper end of the lower container 1, and the placed upper container 1 is then slid, making the stacking operation easier.

[0042] At least one of the first lifting handles 41 and the second lifting handles 42 is provided in plural numbers and spaced apart from each other in the horizontal direction. In the first embodiment, as shown in Fig. 2, both the first lifting handles 41 and the second lifting handles 42 are provided in pairs and spaced apart from each other in the horizontal direction.

[0043] When the container 1 is tilted in the short-side direction, i.e., when the container 1 is tilted at an angle such that the left end is higher and the right end is lower, as shown in FIG. 4, the height of the second vertical position 52 on the left side and the first vertical position 51 on the right side are approximately the same. In this case, the line connecting the second lifting handle 42 on the left side and the first lifting handle 41 on the right side is horizontal, allowing a worker to lift the container 1 by, for example, holding the second lifting handle 42 on the left side with their left hand and the first lifting handle 41 on the right side with their right hand. This allows the worker to lift the container 1 naturally in a physically symmetrical position, i.e., without being aware of the difference between the left and right sides even if the positions are not strictly symmetrical. Furthermore, when stacking, the upper end of the bottom 20 of the upper container 1 tilted in the short-side direction is placed on the upper end of the lower container 1, and the placed upper container 1 can then be slid, making stacking easier.

[0044] Furthermore, when stacking, the corner located at the upper end of the bottom 20 of the upper container 1, which is inclined in both the longitudinal and lateral directions, is placed on the upper end of the lower container 1, and the placed upper container 1 is then slid, making stacking easier.

[0045] Furthermore, since an engaging protrusion 211 is formed on the first side wall 21 and an opening 221 is formed on the second side wall 22, when the container 1 is lifted by holding the second lifting handle 42, the upper end of the engaging protrusion 211 bites into the upper end surface of the opening 221, making the first side wall 21 less likely to deform.

[0046] Next, the lifting handles will be further described. As shown in FIG. 2, the first lifting handle 41 and the second lifting handle 42 are inclined vertically in the horizontal direction along the outer surface of the first side wall 21. FIG. 5A is an enlarged view of the second lifting handle 42 on the left side of the front first side wall 21, and FIG. 5B is a perspective view of the second lifting handle 42 as seen from the rear and diagonally below on the right side. As shown in FIG. 5A, the lower end 421 and the upper end 422 of the second lifting handle 42 on the left side of the front first side wall 21 are inclined so that they are positioned downward as they move toward the center of the first side wall 21. Furthermore, as shown in FIG. 2, the lower end 411 and the upper end 412 of the first lifting handle 41 on the left side of the front first side wall 21 are also inclined so that they are positioned downward as they move toward the center of the first side wall 21. That is, in all of the first lifting handles 41 and second lifting handles 42 of this container 1, the lower and upper ends are inclined so that they are positioned lower as they approach the center of the first side wall 21.

[0047] In addition, the lower end 411 and upper end 412 of the first lifting handle 41 on the right side of the front first side wall 21, and the lower end 421 and upper end 422 of the second lifting handle 42 are also inclined so that they are positioned lower as they move toward the center of the first side wall 21.

[0048] As a result, when an operator holds the first lifting handle 41 or the second lifting handle 42 on the left side with his or her left hand and the first lifting handle 41 or the second lifting handle 42 on the right side with his or her right hand, the operator's hand can easily align with the first lifting handle 41 or the second lifting handle 42 in the left-right direction, making it easier for the operator to lift the container 1. That is, when the operator holds the first lifting handle 41 or the second lifting handle 42 on the left side with his or her left hand, the index finger of the left hand, which is located at the left end, is higher than the little finger of the left hand, which is located toward the center, and the fingertips of each finger from the index finger to the little finger slope downward toward the center, and this slope follows the slope of the first lifting handle 41 or the second lifting handle 42 on the left side. Similarly, on the right side, the fingertips of each finger from the index finger to the little finger slope downward toward the center, and this slope follows the slope of the first lifting handle 41 or the second lifting handle 42 on the right side. Therefore, the position of each finger relative to the first lifting handle 41 or the second lifting handle 42 does not vary, making it easy to hold the first lifting handle 41 or the second lifting handle 42 with the hand.

[0049] 5B, the ceiling surface 423 of the second lifting handle 42 is inclined so that it becomes lower as it moves outward from the outer surface of the first side wall 21. The ceiling surface 423 is the downward-facing surface of the lifting handle that an operator can support with their hand from below. Note that not only the second lifting handle 42, but all of the first lifting handles 41 and second lifting handles 42 of this container 1 have ceiling surfaces that are inclined so that they become lower as they move outward from the outer surface of the first side wall 21.

[0050] As a result, when a worker holds the first lifting handle 41 or the second lifting handle 42, the hand can easily fit along the ceiling surface in the front-to-back and up-down directions, making it easier for the worker to lift the container 1. In other words, when the worker holds the first lifting handle 41 or the second lifting handle 42, the fingertips point diagonally upward and backward, and the pads of the fingers are inclined to be positioned upward as they approach the outer surface of the first side wall 21, and this inclination follows the inclination of the ceiling surface of the first lifting handle 41 or the second lifting handle 42. As a result, a wide area of ​​the pads of the fingers contacts the ceiling surface of the first lifting handle 41 or the second lifting handle 42, preventing localized loads from being applied to the fingers, making it less likely that the worker will feel pain in the fingers when lifting the container 1.

[0051] Furthermore, the outer edge (lower edge 421) of the ceiling surface 423 is formed to have a beaded shape. Note that the outer edges of the ceiling surface 423 of not only this second lifting handle 42 but all of the first lifting handles 41 and second lifting handles 42 of this container 1 are formed to have a beaded shape. This makes it easier for an operator's hand to fit along the ceiling surface in the front-to-back and up-to-down directions when holding the first lifting handle 41 or the second lifting handle 42 with their hand.

[0052] (2) Second embodiment Next, a second embodiment will be described with reference to Fig. 6. The second embodiment is mostly the same as the first embodiment, and therefore, explanations that overlap with the first embodiment will be omitted.

[0053] In the first embodiment, two first lifting handles 41 and two second lifting handles 42 are provided, spaced apart from each other in the horizontal direction. In contrast, in the second embodiment, two first lifting handles 41 are provided, spaced apart from each other in the horizontal direction, but only one second lifting handle 42 is provided in the center in the left-right direction.

[0054] This ensures the functionality of the second lifting handles 42 while reducing the number of second lifting handles 42 and reducing the complicated structure of the exterior. Also, since two first lifting handles 41 are provided on the upper side, it is easy to lift the container 1 with both hands when it is placed on the ground or floor.

[0055] (3) Third embodiment Next, a third embodiment will be described with reference to Fig. 7. The third embodiment is mostly the same as the first embodiment, and therefore, explanations that overlap with the first embodiment will be omitted.

[0056] In the first embodiment, two first lifting handles 41 and two second lifting handles 42 are provided, spaced apart from each other in the horizontal direction. In contrast, in the third embodiment, two second lifting handles 42 are provided, spaced apart from each other in the horizontal direction, but only one first lifting handle 41 is provided in the center in the left-right direction.

[0057] This makes it possible to reduce the number of first lifting handles 41 and reduce the complicated structure of the outer surface while ensuring the function of the first lifting handles 41. Also, since two second lifting handles 42 are provided on the upper side, it is easy to keep the container 1 at a high position when it is lifted.

[0058] (4) Fourth embodiment Next, a fourth embodiment will be described with reference to Fig. 8. The fourth embodiment is mostly the same as the first embodiment, and therefore, explanations that overlap with the first embodiment will be omitted.

[0059] In the fourth embodiment, the depth of the ceiling surface 423 of the second lifting handle 42 (i.e., the length from the front end to the rear end) is formed so that it is longer toward the center in the left-right direction. Note that not only for this second lifting handle 42, but for all of the first lifting handles 41 and second lifting handles 42 of this container 1, the depth of the ceiling surface is formed so that it is longer toward the center in the left-right direction.

[0060] This makes it easier for an operator to hold the lifting handle with his or her hand along the ceiling surface in the front-to-back and left-to-right directions, making it easier for the operator to lift the container 1.

[0061] (5) Fifth embodiment Next, a fifth embodiment will be described with reference to Fig. 9. The fifth embodiment is mostly the same as the first embodiment, and therefore, explanations that overlap with the first embodiment will be omitted.

[0062] In the fifth embodiment, the depth of the ceiling surface 423 of the second lifting handle 42 (i.e., the length from the front end to the rear end) is formed to be longer toward the right. Note that not only for this second lifting handle 42, but for all of the first lifting handles 41 and second lifting handles 42 of this container 1, the depth of the ceiling surface is formed to be longer toward the outside in the left-right direction.

[0063] This makes it easier for an operator to hold the lifting handle with his or her hand along the ceiling surface in the front-to-back and left-to-right directions, making it easier for the operator to lift the container 1.

[0064] (6) Variations The partition member is an optional configuration, and the container 1 does not necessarily have to include it.

[0065] The locking member 3 has an optional configuration, and the container 1 does not necessarily have to include the locking member 3. In this case, for example, by forming an engaging portion on each first side wall 21 that detachably engages with each second side wall 22, the shape of the container 1 in the assembled state can be maintained.

[0066] When a plurality of first lifting handles 41 or second lifting handles 42 are provided, the number of the handles does not have to be two, but may be three or more.

[0067] The first lifting handle 41 or the second lifting handle 42 may be formed by a through hole formed in the first side wall 21 .

[0068] The second lifting handle 42 may be formed on the lower end of the first side wall 21 .

[0069] Instead of both the first lifting handle 41 and the second lifting handle 42, only one of the first lifting handle 41 and the second lifting handle 42 may be inclined vertically in the horizontal direction along the outer surface of the first side wall 21. Furthermore, neither the first lifting handle 41 nor the second lifting handle 42 may be inclined vertically in the horizontal direction along the outer surface of the first side wall 21.
