Description

[Technical Field]

[0001] The present invention relates to a container with a handle used for transporting articles, etc. [Background technology]

[0002] Conventionally, there has been known a container that includes a container body having a bottom wall component that is generally rectangular in plan view and side wall components extending upward from each side edge of the bottom wall component, and a handle that is rotatably connected to the container body and configured to be able to change its position between a reclined position in which it extends along the edge of the opening of the container body and a rotated position in which it rotates upward from the reclined position around an axis and extends in a direction intersecting the edge of the opening of the container body. There is also a technology in which the handle in the reclined position is configured to be slidable along the edge of the opening of the container body (see, for example, Patent Document 1, etc.). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Publication No. 3001367 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when sliding the handle in the tilted position along the opening edge of the container body, there is a concern that the handle may shift (be deformed or displaced) in the horizontal direction that intersects with the sliding direction. In that case, not only will the operability of sliding the handle decrease, but if the handle is forcibly slid in a shifted state, there is a risk that the shaft will be damaged or that it will fall off the shaft support.

[0005] The present invention has been made to solve the problems exemplified above, and its object is to provide a container that allows the handle to be slid appropriately when in a reclined position. [Means for solving the problem]

[0006] The following describes each means suitable for achieving the above objects, etc., by item. Note that, as necessary, the effects and advantages specific to the corresponding means will be added.

[0007] Means 1. A container comprising a generally box-shaped container body that opens upward, and a handle that is rotatably connected to the edge of the opening of the container body and is configured to be able to change its position between a reclined position in which it extends along the edge of the opening of the container body and a rotated position in which it rotates upward from the reclined position and extends in a direction that intersects with the edge of the opening of the container body, and wherein the handle in the reclined position can slide along the edge of the opening of the container body, the container body includes a body-side shaft mechanism that supports the handle; a restricting means for restricting displacement of the handle in the horizontal direction intersecting with the sliding direction of the handle in the tilted position at a position different from the main body side shaft mechanism; 、 The handles are provided as a pair on either side of the central portion of the container body in the sliding direction, The handles in the reclined position are configured to be slidable between a first position where the pair of handles are the farthest apart from each other, allowing another container body to be inserted into the container body through the space between the pair of handles, and a second position where the pair of handles are the closest to each other, a portion of which is located on the inner periphery of the opening edge of the container body in a plan view, allowing another container body to be stacked above the pair of handles, the regulating means is configured to be able to regulate displacement of the handle in the reclined posture in a horizontal direction intersecting with the sliding direction at a position different from that of the main body-side shaft mechanism, regardless of whether the handle is in the first position or the second position, the container body includes a mounting portion on which the handle in the reclined position can be mounted, and a guide protrusion protruding upward from the mounting portion; The handle comprises a pair of substantially parallel, substantially linear support parts, a connecting part connecting one end of the pair of support parts, a shaft part provided on the other end side of each of the support parts, and a protrusion receiving part provided at the boundary between the support parts and the connecting part, which receives the guide protrusion when the handle is in the reclined position, and which abuts against or is close to at least one of the inner surface, which is the surface on the inner side of the container body, and the outer surface, which is the surface on the outer side of the container body, of the guide protrusion; The guide protrusion and the protrusion receiving portion constitute the restriction means, At least when the handle is in the first position, the outer surface of the guide protrusion abuts or is close to the inner surface of the support portion, which is the inner surface of the container body, The inner surface of the support portion and the protrusion receiving portion are provided continuously. A container characterized by:

[0008] According to Means 1, when a handle in a reclined position is slid, not only the peripheral portion of the structure (main body-side shaft mechanism) that pivotally supports the handle but also the restricting means can restrict misalignment (deformation / displacement) of the handle in a horizontal direction (lateral direction) that intersects with the normal sliding direction. This more reliably prevents, for example, situations in which the handle becomes misaligned when sliding a handle in a reclined position, making it difficult to perform the sliding operation or applying a relatively large load to the structure that pivotally supports the handle. Therefore, the handle in a reclined position can be slid relatively smoothly while preventing damage to the structure that pivotally supports the handle and the handle from falling off, thereby improving operability and workability when sliding the handle.

[0010] Also, This more reliably achieves the effect of improving operability when sliding the handle in the reclined position. Also, because the regulating means regulates the handle in the second position from shifting, it is possible to stabilize the state in which another container is stacked above a container whose handle is in the second position.

[0012] moreover, The protrusion receiving portion is provided at the boundary between the support portion and the connecting portion. This effectively restricts lateral displacement of the handle in a position that is as far away from the shaft as possible and prone to lateral displacement when the handle is in the reclined position. This makes it possible to further stabilize the reclined position and the sliding of the handle.

[0013] Furthermore, at least when the handle is in the first position, the outer surface of the guide protrusion abuts or is close to the inner surface of the support part, and lateral displacement of the handle in the reclined position is restricted not only in the protrusion receiving part but also in the support part. Therefore, when the handle is in the first position and around the first position, sliding can be further stabilized.

[0014] Furthermore, because the inner surface of the support part and the protrusion receiving part are continuous, the guide protrusion continues to be received in the protrusion receiving part even when the handle in the reclined position moves between the first position and the second position. Therefore, for example, when the guide protrusion changes from a state in which it is not received in the protrusion receiving part to a state in which it is received, it is possible to prevent a situation in which the guide protrusion hits the protrusion receiving part and damages the guide protrusion or the protrusion receiving part, while also making it possible to slide the handle more smoothly.

[0015] Furthermore, when the inner side of the protrusion receiving portion abuts or is close to at least the outer side of the outer and inner sides of the guide protrusion, it is possible to prevent the handle (especially the connecting portion side on which the upper container is placed) from falling inward into the container body when the handle is in the second position (container stacking state).

[0016] means 2 The handle has a curved portion at the boundary between the support portion and the connecting portion, The protrusion receiving portion is provided on the curved portion, The curved portion has an inner curved surface on the inner periphery side of the handle and an outer curved surface on the outer periphery side of the handle, The radius of curvature of the outer curved surface is smaller than the radius of curvature of the inner curved surface. 1 The container described in

[0017] means 2 According to the invention, by making the inner curved surface of the curved portion a relatively gently curved surface and the outer curved surface a relatively steeply curved surface, it is possible to maximize the width of the curved portion in the sliding direction of the handle in the reclined position, and therefore the length of the protrusion receiving portion. Therefore, while reinforcing the curved portion (corner portion) of the handle where the protrusion receiving portion is provided (for example, while suppressing deformation of the corner portion of the handle when stacked), it is possible to increase the range (area) where the inner side surface of the protrusion receiving portion and the guide protrusion face each other (can come into contact) in the sliding direction of the handle, thereby further stabilizing the sliding of the handle.

[0019] An embodiment will be described below with reference to the drawings. As shown in Fig. 1 etc., the container 1 comprises a container body 2 having a generally rectangular box shape that opens upward, and a handle 3 that is rotatably connected to the edge of the opening of the container body 2. The handles 3 are provided in pairs on either side of the center of the container body 2 in the longitudinal width direction. The container body 2 and the handle 3 are each made of polypropylene and then connected to each other.

[0020] 2 and 3, the container body 2 includes a bottom wall 11 having a generally rectangular shape in a plan view, long-side sidewalls 12 extending upward from each long side of the bottom wall 11, and short-side sidewalls 13 extending upward from each short side of the bottom wall 11. In this embodiment, the long-side sidewalls 12 and the short-side sidewalls 13 extend upward at an incline outward from the container body 2. This configuration allows the containers 1 to be stacked (nested) by inserting an upper container 1 (container body 2) into the inside of a lower container 1 (container body 2), as shown in FIG.

[0021] As shown in Figures 2 and 3, the container body 2 is provided with a long side upper flange portion 14 extending outward from the upper edge of the long side side wall portion 12 to the outside of the container body 2, a short side upper flange portion 15 extending outward from the upper edge of the short side side wall portion 13 to the outside of the container body 2 and having both ends connected to the ends of the long side upper flange portion 14, a folded portion 16 extending downward from the outer peripheral edge of the upper flange portions 14, 15, and a connecting rib 17 (see Figure 3) connecting the upper flange portions 14, 15, the folded portion 16, and the side wall portions 12, 13.

[0022] 1 and 9, a body-side shaft mechanism 21 is provided in each long-side upper flange 14 in a range including the center in the longitudinal width direction of the container body 2. The body-side shaft mechanism 21 is formed by bulging outward at a portion on the outer periphery of the container body 2 (a portion spaced outward a predetermined distance or more from the opening edge of the container body 2). Both ends of the body-side shaft mechanism 21 are inclined so that the width of the body-side shaft mechanism 21 gradually narrows upward when viewed from the front. That is, in order to provide body-side shaft mechanism 21, the general portion of long-side upper flange 14 is cut out at a portion on the outer periphery of container body 2, and body-side shaft mechanism 21 is composed of shaft wall 22 that is generally trapezoidal in front view and extends upward from the inner edge of container body 2 at the cutout portion, upper wall 23 that extends outward from the upper side of shaft wall 22 to the outside of container body 2, inclined wall 24 that extends outward from the oblique side of shaft wall 22, and folded portion 16 that extends downward from the outer edges of upper wall 23 and inclined wall 24. The portion of folded portion 16 that corresponds to body-side shaft mechanism 21 is displaced upward from the general portion of folded portion 16, following the lines of upper wall 23 and inclined wall 24. The shaft wall portion 22 is configured by forming a hole portion penetrating the shaft wall portion 22, and is provided with a support portion 25 that supports the shaft portion 33 of the handle 3, which will be described in detail later. Since the handles 3 are provided in pairs, a pair of support portions 25 is provided on the shaft wall portion 22 of each main body side shaft mechanism portion 21.

[0023] 3, the container body 2 is provided with short-side lower protrusions 26 that protrude downward from each short side edge of the underside of the bottom wall 11, and support ribs 27 that protrude downward in a generally lattice pattern from the underside of the bottom wall 11 in the range between the pair of short-side lower protrusions 26. When the container body 2 is placed on an installation surface such as a floor, the short-side lower protrusions 26 and the support ribs 27 come into contact with the installation surface.

[0024] As shown in FIGS. 4 and 5 , the handle 3 includes a pair of substantially parallel, substantially linear support portions 31 and a connecting portion 32 connecting one end of the pair of support portions 31, forming a substantially U-shape in a front view. Furthermore, each support portion 31 has a shaft portion 33 protruding outward from the outer surface of the other end thereof. As shown in FIG. 1 and other figures, each shaft portion 33 is inserted into and pivotally supported by a supporting portion 25 of the shaft wall portion 22 of each main body-side shaft mechanism portion 21 of the container body 2. This allows the handle 3 to be positioned between a reclined position in which it extends along the opening edge of the container body 2 and a pivoted position in which it rotates upward from the reclined position and extends in a direction intersecting the opening edge (long-side upper flange portion 14) of the container body 2. When the handle 3 is in the reclined position, the handle 3 is configured to rest on the upper flange portions 14, 15 of the container body 2. In this embodiment, the upper flange portions 14, 15 form a resting portion.

[0025] As shown in Figures 1 and 7, each of the support portions 25 provided on each of the main body side shaft mechanism portions 21 of the container main body 2 is a long hole with a relatively long width in the longitudinal width direction of the container main body 2, and is configured so that the handle 3 in a reclined position can slide in the longitudinal width direction of the container main body 2 along the opening edge of the container main body 2. In this embodiment, the handle 3 in the reclined position is configured to be slidable between a first position (see Figure 1) in which the pair of handles 3 are at the farthest apart and are almost entirely located on the outer periphery of the opening edge of the container body 2 in a planar view (particularly in this embodiment, the support portion 31 is placed on the upper flange portion 14 on the long side and the connecting portion 32 is placed on the upper flange portion 15 on the short side), and a second position (see Figure 2) in which the pair of handles 3 are at their closest together and are located on the inner periphery of the opening edge of the container body 2 in a planar view (particularly in this embodiment, the support portion 31 is placed on the upper flange portion 14 on the long side and the connecting portion 32 is located above the opening of the container body 2).

[0026] When nesting containers 1 as described above (see FIG. 11), by setting the pair of handles 3 of the lower container 1 to the first position, the container body 2 of the upper container 1 can be inserted into the container body 2 of the lower container 1 between the pair of handles 3 of the lower container 1 without being obstructed by the handles 3 of the lower container 1. When the containers 1 are nested, the lower end of the connecting rib 17 of the upper container 1 is supported by abutting against the upper surface of the handle 3 of the lower container 1 in its reclined position.

[0027] 12, by placing the pair of handles 3 in the second position, it becomes possible to stack another container body 2 above the pair of handles 3 (to stack containers 1). In addition, as shown in FIG. 3, on the underside of the container body 2 (bottom wall portion 11), there is a gap between each of the short-side lower protrusions 26 and the support rib 27, and as shown in FIG. 13, when the containers 1 are stacked, the connecting portions 32 (from the area near the boundary with one support portion 31 to the area near the boundary with the other support portion 31) of the pair of handles 3 of the lower container 1 are inserted into the gap. This restricts displacement of the pair of handles 3 toward the first position, and also restricts relative displacement in the horizontal direction between the upper and lower containers 1. 2, 4, etc., a portion of the connecting portion 32 of the handle 3, including the center in its extension direction, is provided with a handle portion 37. The upper portion of the handle 3 when the handle 3 is in the reclined position is more rounded than the other portions in cross section. Furthermore, as shown in FIGS. 3 and 13, a pair of lower guide ribs 38 are provided between each of the short side lower protrusions 26 and the support rib 27. The lower portions of the lower guide ribs 38 have a curved portion corresponding to the curvature of the handle portion 37. When the containers 1 are stacked, each pair of lower guide ribs 38 of the upper container 1 abuts against and is supported by portions near both ends of the handle portion 37 of the lower container 1. Furthermore, when stacking the containers 1, the curved shape of the handle portion 37 of the lower container 1 and the inclined curved shape of the lower guide rib 38 of the upper container 1 allow the connecting portion 32 of each handle 3 of the lower container 1 to be inserted relatively smoothly between the lower short-side protrusions 26 of the upper container 1 and the support rib 27. Furthermore, as shown in Figure 14, when the containers 1 are stacked, the lower guide rib 38 of the upper container 1 abuts or is close to the step formed between the handle portion 37 and the general portions on both sides of it of the connecting portion 32 of the handle 3 of the lower container 1, and this configuration also restricts relative displacement of the upper and lower containers 1 in the short width direction of the container body 2.

[0028] The shaft 33 has a generally oval cross section (a rectangular shape with each short side of the rectangle that widens along the extension direction of the support part 31 being generally arc-shaped), and the vertical width of each pivot support part 25 is formed slightly larger than the long axis of the cross section of the shaft 33 at the end on the short side side wall part 13 side, as shown in Fig. 7, while the portion closer to the center in the longitudinal width direction of the container body 2 than the end is formed smaller than the long axis of the cross section of the shaft 33. For this reason, the handle 3 can be set to a rotating position only when the shaft 33 is positioned at the end on the short side side wall part 13 side of the pivot support part 25 (first position), and the handle 3 can be configured to slide horizontally by setting it to a reclined position.

[0029] 7 and other figures, the container body 2 is provided with guide protrusions 41 that protrude upward from positions of the long-side upper flange portions 14 that are spaced apart from the body-side shaft mechanism portion 21 toward each of the short-side side wall portions 13 in the longitudinal width direction of the container body 2. Each guide protrusion 41 protrudes upward from the inner edge of the long-side upper flange portions 14 of the container body 2, and extends to the connecting portions (corner portions) between the long-side upper flange portions 14 and the short-side upper flange portions 15.

[0030] 4, 5, 8, etc., the handle 3 is provided with a protrusion receiving portion 42 (having a substantially U-shaped cross section) that is provided at the boundary between the support portion 31 and the connecting portion 32 and receives the guide protrusion 41 when the handle 3 is in the reclined position. The protrusion receiving portion 42 is configured to abut against or be close to the inner surface, which is the surface on the inner side of the container body 2, and the outer surface, which is the surface on the outer side of the container body 2, of the guide protrusion 41 received in the protrusion receiving portion 42 (see FIG. 10). In other words, displacement of the handle 3 in the reclined position in the horizontal direction that intersects with the sliding direction is restricted even at positions other than the body-side shaft mechanism portion 21. In this embodiment, the guide protrusion 41 and the protrusion receiving portion 42 constitute a restricting means.

[0031] 8, 9, etc., the guide protrusion 41 is received in the protrusion receiving portion 42 whether the handle 3 is in the first position or the second position, or whether the handle 3 is in any position between the first and second positions. In addition, as shown in FIG. 9, the inner surface of the support portion 31, which is the surface facing the container body 2, and the protrusion receiving portion 42 are provided continuously. In particular, in this embodiment, as shown in FIG. 6, the inner surface of the support portion 31 and the inner side surface of the protrusion receiving portion 42 are provided continuously and substantially in a straight line. Therefore, as shown in FIG. 8, when the handle 3 is in the first position, the outer surface of the guide protrusion 41 is configured to abut or come into close proximity not only with the inner side surface of the protrusion receiving portion 42 but also with the inner surface of the support portion 31.

[0032] For example, when a force acts on the handle 3 in a reclined position such that one of the pair of support portions 31 is displaced outward from the container body 2, the protrusion receiving portion 42 corresponding to that support portion 31 abuts against the inner surface of the guide protrusion 41, and the outer surface of that support portion 31 abuts against the inner surface of the shaft wall portion 22 of the body side shaft mechanism portion 21, and further, the protrusion receiving portion 42 corresponding to the other support portion 31 (and, when in the first position, the inner surface of the support portion 31) abuts against the outer surface of the guide protrusion 41, thereby restricting the displacement of the handle 3 in the short width direction of the container body 2.

[0033] 4, 6, etc., the handle 3 has a curved portion 44 at the boundary between the support portion 31 and the connecting portion 32, and the above-mentioned protrusion receiving portion 42 is provided in the curved portion 44. Furthermore, the curved portion 44 has an inner curved surface 45 on the inner periphery side of the handle 3 and an outer curved surface 46 on the outer periphery side of the handle 3, and the radius of curvature of the outer curved surface 46 is configured to be smaller than the radius of curvature of the inner curved surface 45. Furthermore, as shown in FIG. 8, both ends of the upper edge of the guide protrusion 41 are inclined surfaces. Therefore, when the handle 3 slides, interference between the wall portions constituting the inner curved surface 45 and the wall portions constituting the outer curved surface 46 and both ends of the guide protrusion 41 is reliably avoided.

[0034] As described above in detail, according to this embodiment, when the handle 3 in the reclined position is slid, not only the peripheral portion of the structure (main body-side shaft mechanism 21) that pivotally supports the handle 3 but also the guide protrusion 41 and the protrusion receiving portion 42 can restrict misalignment (deformation or displacement) of the handle 3 in the horizontal direction (lateral direction) that intersects with the normal sliding direction. This more reliably prevents, for example, situations in which the handle 3 becomes misaligned when sliding the handle 3 in the reclined position, making it difficult to perform the sliding operation or applying a relatively large load to the structure that pivotally supports the handle 3. Therefore, the handle 3 in the reclined position can be slid relatively smoothly while preventing damage or detachment of the structure that pivotally supports the handle 3, thereby improving operability and workability when sliding the handle 3.

[0035] Furthermore, the guide protrusion 41 and the protrusion receiving portion 42 are configured to be able to restrict displacement of the handle 3 in the horizontal direction intersecting the sliding direction when the handle 3 is in the reclined position at a position different from the main body-side shaft mechanism portion 21, regardless of whether the handle 3 is in the first position or the second position. This more reliably achieves the effect of improving operability when sliding the handle 3 in the reclined position. Furthermore, because the guide protrusion 41 and the protrusion receiving portion 42 restrict displacement of the handle 3 when in the second position, it is possible to stabilize the state in which another container 1 is stacked above a container 1 with the handle 3 in the second position.

[0036] Furthermore, the protrusion receiving portion 42 of the handle 3 is provided at the boundary between the support portion 31 and the connecting portion 32. This effectively restricts lateral displacement of the handle 3 at a position of the handle 3 in the reclined position that is as far away as possible from the shaft portion 33 and is prone to lateral displacement. This therefore makes it possible to further stabilize the state in which the handle 3 is reclined and the sliding of the handle 3.

[0037] Furthermore, when the handle 3 is in the first position, the outer surface of the guide protrusion 41 abuts or is close to the inner surface of the support part 31, and lateral displacement of the handle 3 in the reclined position is restricted not only at the protrusion receiving part 42 but also at the support part 31. Therefore, the opposing area between the support part 31 of the handle 3 and the main body side shaft mechanism part 21 (shaft wall part 22) is reduced, and it is possible to further stabilize the state in which the handle 3 is in the first position, in which the connecting part 32 side of the handle 3 is likely to shift laterally, and the sliding around the first position.

[0038] Furthermore, because the inner surface of the support portion 31 and the protrusion receiving portion 42 are continuous, even when the handle 3 in the reclined position moves between the first position and the second position, the guide protrusion 41 continues to be received in the protrusion receiving portion 42. Therefore, for example, when the guide protrusion 41 is changed from a state in which it is not received in the protrusion receiving portion 42 to a state in which it is received, it is possible to prevent a situation in which the guide protrusion 41 collides with the protrusion receiving portion 42 and the guide protrusion 41 or the protrusion receiving portion 42 is damaged, while also making it possible to slide the handle 3 more smoothly.

[0039] Furthermore, when the inner side of the protrusion receiving portion 42 abuts or is close to at least the outer side of the outer and inner sides of the guide protrusion 41, it is possible to prevent the handle 3 (especially the connecting portion 32 side on which the upper container 1 is placed) from falling inward into the container body 2 when the handle 3 is in the second position (stacking state of the containers 1).

[0040] In addition, the handle 3 has a curved portion 44 at the boundary between the support portion 31 and the connecting portion 32, and the protrusion receiving portion 42 is provided in the curved portion 44. Furthermore, the curved portion 44 is configured so that the radius of curvature of the outer curved surface 46 is smaller than the radius of curvature of the inner curved surface 45. This makes it possible to ensure as large a width as possible for the curved portion 44 in the sliding direction of the handle 3 in the reclined position, and therefore the length of the protrusion receiving portion 42. Therefore, while reinforcing the curved portion 44 (corner portion) of the handle 3 where the protrusion receiving portion 42 is provided (for example, while suppressing deformation of the corner portion of the handle 3 when stacked), it is possible to increase the range (area) over which the inner side surface of the protrusion receiving portion 42 faces (can come into contact with) the guide protrusion 41 in the sliding direction of the handle 3, thereby further stabilizing the sliding of the handle 3.

[0041] The present invention is not limited to the above-described embodiment, and may be implemented as follows: Of course, other applications and modifications not exemplified below are also possible.

[0042] (a) In the above embodiment, the handle 3 in the reclined position is configured to be movable between a first position where the support portion 31 and the connecting portion 32 are placed on the long side upper flange portion 14 and the short side upper flange portion 15, and a second position where the support portion 31 is placed on the long side upper flange portion 14 and the connecting portion 32 is located above the opening of the container body 2, but this configuration is not particularly limited. For example, when the handle 3 is moved from the pivoted position to the reclined position, the connecting portion 32 of the handle 3 is positioned so as to protrude outward from the short side upper flange portion 15 of the container body 2, and by sliding the handle 3 from this state toward the center of the container body 2 in the longitudinal width direction, the entire handle 3 may be configured to fit inside the outer dimensions of the container body 2 in a plan view (a configuration in which the containers 1 are not stacked). Although not specifically mentioned in the above embodiment, in the above embodiment, the inner portion (inner curved surface 45) of the corner portion of the handle 3 in the first position when viewed in a plane is located on the inner side of the opening edge of the container body 2, but the entire handle 3 in the first position may also be configured to be located on the outer side of the opening edge of the container body 2.

[0043] (b) In the above embodiment, the guide protrusion 41 is provided on the long side upper flange portion 14, and the protrusion receiving portion 42 (groove) is provided on the handle 3. However, for example, the guide protrusion 41 may be provided on the handle 3, and the protrusion receiving portion 42 (groove) may be provided on the long side upper flange portion 14. Also, in the above embodiment, the protrusion receiving portion 42 has a generally U-shaped cross section and is configured to abut or be close to (be able to abut) both the outer surface and the inner surface of the guide protrusion 41. However, it is sufficient that the protrusion receiving portion 42 is configured to abut or be close to (be able to abut) at least one of the outer surface and the inner surface of the guide protrusion 41. In addition, in the above embodiment, the shaft portion 33 is configured to protrude outward from the outer surface of the support portion 31.
