Description

The present invention relates to a container with a handle used for transporting items, etc.

Conventionally, a container has been known that includes a container body having a bottom wall component that is generally rectangular in plan view and side walls extending upward from each side edge of the bottom wall component, and a handle that is rotatably connected to the container body and is configured to be able to change its position between a reclined position in which it extends along the opening edge 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 opening edge of the container body. There is also technology that configures a handle in a reclined position so that it can slide along the opening edge of the container body (see, for example, Patent Document 1).

Publication No. 3001367

However, when sliding a handle in a reclined position along the opening edge of the container body, there is a concern that the handle may shift (become deformed or displaced) in a horizontal direction that intersects with the sliding direction. In this case, not only will the handle be less easy to slide, but forcing the handle to slide in a misaligned state could damage the shaft or cause it to fall off the shaft support.

The present invention was made to solve the problems exemplified above, and its purpose is to provide a container that allows the handle to be slid appropriately when in a reclined position.

Below, we will explain each means suitable for achieving the above objectives, etc., by item. Where necessary, we will also note the specific effects, etc., of the corresponding means.

Means 1. A container comprising a generally box-shaped container body that opens upward, and a handle that is rotatably connected to the opening edge of the container body and is configured to be able to change its position between a reclined position in which it extends along the opening edge 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 opening edge of the container body, and wherein the handle in the reclined position can slide along the opening edge 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 reclined position in a horizontal direction intersecting with the sliding direction of the handle 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,
A container characterized in that the inner surface of the support portion and the protrusion receiving portion are provided continuously .

Method 1 allows the regulating means to restrict misalignment (deformation/displacement) of the reclined handle in the horizontal direction (sideways) that intersects with the normal sliding direction when the reclined handle is slid, not only by the peripheral portion of the structure supporting the handle (main body-side shaft mechanism) but also by the regulating means. This more reliably prevents situations such as difficulty in sliding the reclined handle or a relatively large load being applied to the structure supporting the handle due to the handle being misaligned when sliding the reclined handle. Therefore, the reclined handle can be slid relatively smoothly while preventing damage to the structure supporting the handle or the handle falling off, improving operability and workability when sliding the handle.

In addition, the effect of improving operability when sliding the handle in the reclined position is more reliably achieved. Furthermore, since the restricting means restricts displacement of the handle in the second position, it is possible to stabilize the state in which another container is stacked above a container whose handle is in the second position.

Furthermore, a 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.

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 portion, restricting lateral displacement of the handle in a reclined position not only at the protrusion receiving portion but also at the support portion. This further stabilizes sliding when the handle is in the first position and around the first position.

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 and second positions. This prevents the guide protrusion from colliding with the protrusion receiving part and damaging the guide protrusion or protrusion receiving part when, for example, the guide protrusion changes from not being received in the protrusion receiving part to being received, while also allowing the handle to slide more smoothly.

Furthermore, when the inner side of the projection receiving portion abuts or is close to at least the outer side of the outer and inner sides of the guide projection, it is possible to prevent the handle (particularly 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).

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 container according to means 1 , characterized in that the radius of curvature of the outer curved surface is smaller than the radius of curvature of the inner curved surface.

According to Measure 2 , 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 faces (can come into contact with) the guide protrusion in the sliding direction of the handle, thereby further stabilizing the sliding of the handle.

One embodiment will be described below with reference to the drawings. As shown in Figure 1, the container 1 comprises a container body 2 that is roughly a square box-shaped container with an upward opening, and a handle 3 that is rotatably connected to the edge of the opening of the container body 2. A pair of handles 3 are provided on either side of the center of the container body 2 in the longitudinal width direction. The container body 2 and handle 3 are each made of polypropylene and then connected to each other.

As shown in Figures 2 and 3, the container body 2 includes a bottom wall 11 that is generally rectangular in plan view, long side wall portions 12 that extend upward from each long side of the bottom wall 11, and short side wall portions 13 that extend upward from each short side of the bottom wall 11. In this embodiment, the long side wall portions 12 and short side wall portions 13 extend upward at an angle outward from the container body 2. This configuration allows the containers 1 to be stacked (nested) by inserting the upper container 1 (container body 2) inside the lower container 1 (container body 2), as shown in Figure 11.

As shown in Figures 2 and 3, the container body 2 also includes a long-side upper flange portion 14 extending outward from the top of the long-side side wall portion 12, a short-side upper flange portion 15 extending outward from the top of the short-side side wall portion 13 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.

Furthermore, as shown in Figures 1 and 9, a body-side shaft mechanism 21 is provided in each long-side upper flange 14 in a range that includes the center of the container body 2 in the longitudinal width direction. 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 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 the body-side shaft mechanism 21, the general portion of the long-side upper flange 14 is cut out at a portion on the outer periphery of the container body 2, and the body-side shaft mechanism 21 is composed of a shaft wall 22 that is generally trapezoidal in front view and extends upward from the inner edge of the container body 2 at the cutout, an upper wall 23 that extends outward from the upper edge of the shaft wall 22 to the outside of the container body 2, an inclined wall 24 that extends outward from the oblique side of the shaft wall 22, and the folded portion 16 that extends downward from the outer edges of the upper wall 23 and inclined wall 24. The portion of the folded portion 16 that corresponds to the body-side shaft mechanism 21 is displaced upward from the general portion of the folded portion 16, following the lines of the upper wall 23 and inclined wall 24. The shaft wall 22 is also configured with a hole that passes through it, and is provided with a support 25 that supports the shaft 33 of the handle 3, which will be described in detail later. Since a pair of handles 3 are provided, a pair of support 25 is provided on the shaft wall 22 of each main body-side shaft mechanism 21.

In addition, as shown in FIG. 3, the container body 2 has 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-like pattern from the underside of the bottom wall 11 in the area between each 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 support ribs 27 come into contact with the installation surface.

As shown in Figures 4 and 5, the handle 3 has 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 front view. Furthermore, a shaft portion 33 protrudes outward from the outer surface of the other end of each support portion 31. As shown in Figure 1 and other figures, each shaft portion 33 is inserted into and supported by a supporting portion 25 of the shaft wall portion 22 of each body-side shaft mechanism portion 21 of the container body 2. This allows the handle 3 to change its position 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, it 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 the resting portion.

As shown in Figures 1 and 7, each shaft support portion 25 provided on each main body side shaft mechanism portion 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 to allow the handle 3 in a reclined position to 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 handles 3 in the reclined position are slidable between a first position (see FIG. 1) where the pair of handles 3 are furthest apart and are positioned almost entirely on the outer periphery of the opening edge of the container body 2 in a plan view (particularly in this embodiment, the support portion 31 is placed on the long side upper flange portion 14 and the connecting portion 32 is placed on the short side upper flange portion 15), and a second position (see FIG. 2) where the pair of handles 3 are closest to each other and are positioned on the inner periphery of the opening edge of the container body 2 in a plan view (particularly in this embodiment, the support portion 31 is placed on the long side upper flange portion 14 and the connecting portion 32 is positioned above the opening of the container body 2).

When nesting containers 1 as described above (see Figure 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. Furthermore, when the containers 1 are nested, the lower end of the connecting rib 17 of the upper container 1 abuts and is supported by the upper surface of the handle 3 of the lower container 1 in its reclined position.

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). Additionally, as shown in FIG. 3, there is a gap between the lower short-side protrusions 26 and the support ribs 27 on the underside of the container body 2 (bottom wall 11). As shown in FIG. 13, when the containers 1 are stacked, the connecting portions 32 of the pair of handles 3 of the lower container 1 (from the area near the boundary with one support portion 31 to the area near the boundary with the other support portion 31) are inserted into the gap. This restricts the movement of the pair of handles 3 toward the first position and also restricts the relative horizontal movement 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 the 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 each 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. This configuration also restricts relative displacement of the upper and lower containers 1 in the short width direction of the container body 2.

The shaft 33 has a generally oval cross section (a rectangular shape with each short side of the support portion 31 widening in the extension direction, and generally arc-shaped), and the vertical width of each support portion 25 is slightly larger than the long axis of the cross section of the shaft 33 at the end on the short side wall 13 side, as shown in Figure 7, while the portion closer to the center of the container body 2 in the longitudinal width direction than the end is smaller than the long axis of the cross section of the shaft 33. For this reason, the handle 3 can only be rotated when the shaft 33 is positioned at the end on the short side wall 13 side of the support portion 25 (first position), and the handle 3 can be slid horizontally by tilting it down.

As shown in Figure 7 and other figures, the container body 2 is provided with guide protrusions 41 that protrude upward from the long side upper flange portion 14 at positions spaced apart from the body-side shaft mechanism portion 21 toward each short side side wall portion 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 portion 14 of the container body 2 and extends to the connecting portion (corner portion) between the long side upper flange portion 14 and the short side upper flange portion 15.

In contrast, as shown in Figures 4, 5, 8, etc., the handle 3 is provided with a protrusion receiving portion 42 (with a substantially U-shaped cross section) located at the boundary between the support portion 31 and the connecting portion 32, which 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 inner surface of the container body 2, and the outer surface, which is the outer surface of the container body 2, of the guide protrusion 41 received in the protrusion receiving portion 42 (see Figure 10). In other words, horizontal displacement of the handle 3 in the reclined position, which 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.

Furthermore, as shown in Figures 8 and 9, 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. Additionally, as shown in Figure 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 continuous. In particular, in this embodiment, as shown in Figure 6, the inner surface of the support portion 31 and the inner side surface of the protrusion receiving portion 42 are continuous and substantially aligned. Therefore, as shown in Figure 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.

For example, if 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 will abut against the inner surface of the guide protrusion 41, and the outer surface of that support portion 31 will abut against the inner surface of the shaft wall portion 22 of the body-side shaft mechanism portion 21. Furthermore, 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) will abut against the outer surface of the guide protrusion 41, thereby restricting displacement of the handle 3 in the short width direction of the container body 2.

As shown in Figures 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 protrusion receiving portion 42 described above is provided in the curved portion 44. Furthermore, the curved portion 44 has an inner curved surface 45 on the inner periphery of the handle 3 and an outer curved surface 46 on the outer periphery of the handle 3, and the radius of curvature of the outer curved surface 46 is smaller than the radius of curvature of the inner curved surface 45. Furthermore, as shown in Figure 8, both ends of the upper edge of the guide protrusion 41 are inclined. 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.

As described above in detail, according to this embodiment, when sliding the handle 3 in the reclined position, 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 protrusion receiving portion 42 can restrict misalignment (deformation/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 the sliding operation difficult 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, improving operability and workability when sliding the handle 3.

Furthermore, the guide protrusion 41 and protrusion receiving portion 42 are configured to restrict horizontal displacement of the handle 3 in the reclined position, which intersects with the sliding direction, at a position different from the main body-side shaft mechanism 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 protrusion receiving portion 42 restrict displacement of the handle 3 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.

Furthermore, the protrusion receiving portion 42 of the handle 3 is located 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 in the reclined position that is as far away from the shaft portion 33 as possible and prone to lateral displacement. This therefore makes it possible to further stabilize the reclined position of the handle 3 and the sliding of the handle 3.

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 portion 31, restricting lateral displacement of the handle 3 in the reclined position not only at the protrusion receiving portion 42 but also at the support portion 31. This reduces the opposing area between the support portion 31 of the handle 3 and the main body-side shaft mechanism portion 21 (shaft wall portion 22), further stabilizing the handle 3 in the first position, where the connecting portion 32 side of the handle 3 is prone to lateral displacement, and also stabilizing sliding around the first position.

Furthermore, because the inner surface of the support portion 31 and the protrusion receiving portion 42 are continuous, the guide protrusion 41 continues to be received in the protrusion receiving portion 42 even when the handle 3 in the reclined position moves between the first and second positions. This prevents the guide protrusion 41 from colliding with the protrusion receiving portion 42 and damaging the guide protrusion 41 or the protrusion receiving portion 42 when, for example, the guide protrusion 41 changes from not being received in the protrusion receiving portion 42 to being received therein, while also enabling the handle 3 to slide more smoothly.

Furthermore, when the inner side of the projection receiving portion 42 abuts or is close to at least the outer side of the outer and inner sides of the guide projection 41, it is possible to prevent the handle 3 (particularly 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 (container 1 stacking state).

In addition, the handle 3 has a curved portion 44 at the boundary between the support portion 31 and the connecting portion 32, and a 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 allows the width of 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, to be maximized. Therefore, while reinforcing the curved portion 44 (corner portion) of the handle 3 where the protrusion receiving portion 42 is provided (for example, preventing deformation of the corner portion of the handle 3 when stacked), 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 can be increased in the sliding direction of the handle 3, further stabilizing the sliding of the handle 3.

Note that the present invention is not limited to the above-described embodiment, and may be implemented, for example, as follows. Of course, other applications and modifications not exemplified below are also possible.

(a) In the above embodiment, the handle 3 in the reclined position is configured to be movable between a first position in which the support portion 31 and the connecting portion 32 rest on the long side upper flange portion 14 and the short side upper flange portion 15, and a second position in which the support portion 31 rests on the long side upper flange portion 14 and the connecting portion 32 is located above the opening of the container body 2. However, this configuration is not particularly limited. For example, when the handle 3 is reclined from the pivoted position, the connecting portion 32 of the handle 3 may be positioned so as to protrude outward from the short side upper flange portion 15 of the container body 2. By sliding the handle 3 from this position 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 of the handle 3 in the first position in plan view is located more inward than the opening edge of the container body 2, but the entire handle 3 in the first position may be configured to be located more outward than the opening edge of the container body 2.

(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. Furthermore, 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 and inner surfaces 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 and inner surfaces 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. However, the shaft portion 33 may also be configured to protrude inward from the inner surface of the support portion 31 (the body-side shaft mechanism portion 21 protrudes upward from the inner edge of the long side upper flange portion 14). Alternatively, a shaft may be provided on the main body-side shaft mechanism 21, and a shaft support 25 formed by an elongated hole may be provided on the support portion 31 of the handle 3.

(c) In the above embodiment, the container body 2 and handle 3 are made of polypropylene, but they may also be made of other polyolefin-based resins (such as polyethylene) or synthetic resins other than polyolefin-based resins (such as ABS resin, AES resin, acrylic resin, polycarbonate, etc.).
