Description

  The present invention relates to a folding container that is used for transporting articles and the like, and particularly has a handle on a side wall.

  Conventionally, a substantially rectangular plate-like bottom wall portion and side wall portions extending upward from each side portion of the bottom wall portion are configured to be assembled into a box shape that opens upward, and each side wall portion is Folding containers that can be folded over the bottom wall are known. Furthermore, in order to improve the ease of carrying the folded container in the assembled state, there is a technique of forming a “handle” on the side wall (see, for example, Patent Documents 1 and 2).

JP 2001-72104 A Japanese Utility Model Publication No. 5-75128

  However, when the handle is formed by forming an opening portion penetrating in the thickness direction with respect to the side wall portion as in the above-mentioned Patent Document 1, dust, small animals, and the like are inside the container through the opening portion. There is a concern that it will invade.

  In addition, as in Patent Document 2, there is a type in which a handle is formed by projecting a rib outward from a side wall and folding the tip downward. In this case, if the rib for the handle protrudes outward from the outer surface of the side wall, the rib for the handle becomes an obstacle during transportation and storage, or the rib for the handle itself is easily damaged. There is a risk of becoming. For this reason, it is desirable that the rib for the handle is contained within the thickness range of the side wall portion. However, in that case, when the thickness of the side wall portion is thin, the protruding length of the rib to the outside is shortened, and the fingertip is not caught well, so that it does not function well as a handle. The In particular, regarding a foldable folding container, such a concern becomes even more pronounced because it is required to reduce the thickness of the side wall portion in order to keep the height during folding as low as possible.

  The present invention has been made in order to solve the above-described problems and the like, and the purpose thereof is a folding container provided with a handle without incurring problems caused by forming an opening, and The object is to provide a folding container with excellent operability.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to the means to respond | correspond as needed are added.

Means 1. A substantially rectangular plate-like bottom wall portion and sidewall portions extending upward from each side portion of the bottom wall portion, the sidewall portion being configured to be rotatable relative to the bottom wall portion. In the folding container that can be folded so that the side wall portions overlap each other,
A non-use posture that extends along the side wall portion and is arranged side by side on the outer surface side of the side wall portion, and a use posture in which more parts are separated from the side wall portion than in the non-use posture. A folding container characterized in that a handle displaceable between the two is provided.

  According to the means 1, the handle as a handle is in a non-use posture in which the handle is juxtaposed on the outer surface side of the side wall portion, so that the handle does not protrude as far as possible from the side wall portion (for example, the handle is attached to the side wall). Within the thickness range of the part). For this reason, in a state where the folding container is assembled in a box shape and the handle is not used, an extra storage space is required due to the presence of the handle, or the handle itself is easily damaged. Can be prevented. Furthermore, even when the folding container is folded, it is possible to prevent a situation in which the handle interferes to hinder the folding operation of the side wall or the height of the folding container in the folded state increases.

  Moreover, the handle | steering-wheel should just become the shape which is easy to hold | grip by pulling out the handle in a non-use posture from the side wall part to a use posture, for example. For this reason, even under conditions where the thickness of the side wall portion is relatively thin and the handle cannot be secured so much, the thickness of the side wall portion including the handle in a non-use posture is stored as compactly as possible. This makes it possible to make the handle easy to grip in the use posture. Accordingly, it is possible to reduce the thickness of the side wall portion while ensuring the ease of holding the handle (ease of applying force), and thus stabilizing the state in which the handle is held and the folding container is held. In addition, by reducing the thickness of the side wall portion in this manner, the height of the folded container in the folded state can be reduced as much as possible, and weight reduction, resource saving, cost reduction, and the like can be achieved.

  In addition, since there is no need to form an opening that penetrates the side wall portion in the thickness direction to form a handle, foreign matter such as dust and small animals can enter the container through the opening of the side wall portion. It is possible to surely avoid the situation of intruding into the camera. Therefore, hygiene management etc. of the article accommodated in the folding container can be performed more reliably.

  Also, when assembling the folding container, the side wall can be raised by holding the handle, and the assembly workability can be improved. Furthermore, if the side wall is unintentionally displaced from the folded state of the folding container to the folding position side, the handle can be pulled back to reassemble the side wall to make it easier to assemble. Can be returned. Therefore, when there is a folding container that is taken out from the folding container or stacked on top (staged) in order to press the side wall part that has been displaced to the folding position side from the inner surface side and rebuild it. In addition, it is possible to avoid a situation in which the upper folding container has to be lowered.

Mean 2. Range limiting means for limiting the range of displacement of the handle in the non-use posture toward the use posture side is provided,
By applying a force of a specified amount or more toward the use posture side with respect to the handle in a state where the displacement to the use posture side is restricted by the range restriction unit, a displacement allowable range by the range restriction unit is set. The folding container according to claim 1, wherein the folding container is configured to be displaceable to the use posture side beyond the handle.

  According to the means 2, the posture of the handle in a state where the operator does not apply force to the handle can be restricted. Therefore, when folding the folding container, it is possible to prevent the handle from being unintentionally displaced in a posture that hinders the operation of the side wall portion, making it difficult to fold the folding container. . In addition, the handle can be displaced more greatly by applying a force of a specified amount or more toward the use posture with respect to the handle from a state in which the displacement of the handle is restricted by the range limiting means. Accordingly, the posture of the handle can be changed more flexibly, and a sense of stability and the like when carrying the folding container while holding the handle can be improved.

  Note that “the handle is configured to be displaceable by a predetermined amount (predetermined angle) from the non-use posture toward the use posture side even when the handle is restricted by the range restriction means. It may be "being". In this case, until the handle is displaced by a predetermined amount (predetermined angle) from the non-use posture toward the use posture side, the handle is relatively freely displaced without being restricted by the range limiting means. For this reason, the handle | steering-wheel of the non-use posture extended along a side wall part can be pulled out easily, without applying force toward outward. Accordingly, it is possible to improve the operability when the handle in the non-use posture is pulled out to the use posture side.

  Means 3. At least one of the handle and the side wall provided with the handle is formed with a gap for forming a gap between the handle in the non-use posture and the side wall provided with the handle. The folding container according to means 1 or 2, wherein the means is formed.

  According to the means 3, a gap for allowing the operator's fingertip or the like to enter can be formed between the handle in the non-use posture and the side wall provided with the handle. This makes it easier to put a finger on the handle in the non-use posture, and the workability when pulling the handle in the non-use posture to the use posture side or putting the handle in the use posture in the non-use posture Can be improved.

  The gap forming means includes, for example, a recess formed corresponding to the handle in the non-use posture (the grip portion) on the outer surface side of the side wall portion provided with the handle, Examples thereof include an inclined portion that extends obliquely from a surface extending in the thickness direction of the side wall portion to a surface on the side wall portion side, and a convex portion that partially protrudes from the handle in a non-use posture toward the side wall portion.

Means 4. The handle is provided at a grip part that can be gripped by an operator, an extension part that extends in a direction intersecting the grip part, and a tip part of the extension part, and is rotatable with respect to the side wall part And a hinge portion connected to
The handle in the non-use posture has the extending portion extending upward from the hinge portion, and the grip portion of the handle in the non-use posture is more than the upper side portion of the side wall portion. The folding container according to any one of means 1 to 3, wherein the folding container is located below.

  According to the means 4, by pulling the handle in the non-use posture slightly outward, the use posture can be obtained such that the extension portion extends obliquely upward and outward from the hinge portion. When holding the handle gripping part in such a use posture and lifting the folding container, hold the part of the side surface of the folding container located above the handle gripping part by the wrist or arm. Can do. Therefore, the folding container can be lifted in a more stable state.

  Also, for example, when the handle is in a non-use posture, and the extension portion extends downward from the hinge portion, the handle in the non-use posture at the position below the hinge portion of the side wall portion is provided side by side with the side wall portion. In addition to requiring a space to be accommodated, it is necessary to rotate the handle 90 degrees or more in order to obtain a use posture in which the handle is inclined outward and upward as described above. For this reason, when the height of the folding container is not so high compared to the vertical width (height) of the handle in the non-use posture, if the handle is rotated and displaced until it is tilted outward and upward, The gripping part is positioned above the upper part of the folding container or the upper side part, and as described above, the side face of the folding container cannot be held by the wrist or the like.

  In this respect, according to this means 4, since the extension portion extends upward from the hinge portion when the handle is in the non-use posture, the height position of the hinge portion of the handle is set to the side wall portion. Even if it is a folding container that can be set to a low position (possibly near the lower side of the side wall), the side of the folding container can be used as a use posture that extends with the handle inclined upward and outward. It can be carried while holding it with a wrist or the like. In particular, when lifting the folding containers in a stacked state, the wrist or arm is continuously applied to the side wall of the folding container located on the lowermost side and the side wall of the folding container located on the upper side. Since it can hold | maintain, the position shift in the left-right direction between both folding containers can be prevented more reliably. Therefore, it is possible to further stabilize the carrying state.

The part 4 is prevented from falling over. In addition, you may provide the structure (For example, the elastic piece which protrudes from the inner surface of the long side wall part 3 and can contact the inner surface of the short side wall part 4) which prevents the inner wall of the short side wall part 4 from falling down.

  As shown in FIGS. 1 and 4, the upper frame 5 includes a pair of long side portions (long side frame constituting portion 17) respectively connected to the pair of long side wall portions 3, and a pair of short side sides. A pair of short side portions (short side frame constituting portion 18) respectively connected to the side wall portion 4 is provided, and the outer dimension of the upper frame 5 is substantially equal to the outer dimension of the bottom wall portion 2. Further, in the assembled state of the folding container 1, the inner surfaces of the long side wall 3 and the short side wall 4 and the inner peripheral surface of the upper frame 5 are configured to be substantially flush with each other (FIG. 10). reference). In addition, the long side wall portion 3 and the short side wall portion 4 do not protrude beyond the outer peripheral edge of the upper frame 5 or the bottom wall portion 2 even when the folding container 1 is assembled. It is configured. Further, in the folded state of the folding container 1, the folded long side wall 3 and the short side wall 4 overlapping thereabove are accommodated on the inner peripheral side of the upper frame 5 and the bottom wall 2. And the upper frame 5 are configured to contact each other vertically (see FIG. 4).

  As shown in FIG. 3 and the like, on the lower surface side of the bottom wall portion 2, the bottom wall portion 2 protrudes downward from a range located on the inner peripheral side of the upper frame 5 when the folding container 1 is viewed in plan view. A grid-like support rib 19 is provided. And when the folding container 1 is installed on the floor surface, the lower edge part of the support rib 19 contacts the floor surface, and the folding container 1 is supported. When another folding container 1 is stacked above the folding container 1, the support rib 19 of the upper folding container 1 enters the inner peripheral side of the upper frame 5 of the lower folding container 1 and The outer peripheral portion of the lower surface of the bottom wall portion 2 of the folding container 1 is supported by the upper surface of the upper frame 5 of the lower folding container 1. Thereby, the folding containers 1 can be stacked (stacked) up and down while preventing positional displacement in the horizontal direction.

  Furthermore, as shown in FIG. 14, an attached lid member 7 that can close the opening of the folding container 1 can be installed in the folding container 1. As shown in FIG. 15 and FIG. 16, folding containers 1 can be stacked with each other while covering the folding containers 1 with a lid member 7 while maintaining sanitary management of the articles accommodated in the folding containers 1. It is configured. In the present embodiment, the folding container 1 is substantially sealed by covering the lid member 7. Note that the lid member 7 of the present embodiment is made of polypropylene.

  In addition, in the present embodiment, in the state where the folding container 1 is folded, the distance in the vertical direction between the inner surface (the surface facing the upper side) of the short side wall portion 4 and the upper surface of the upper frame 5 is the support rib 19. It is more than the protruding length. For this reason, the folding containers 1 can be stacked not only in the assembled state but also in the folded state. It is also possible to stack the folded folding containers 1 with the lid member 7 covered.

  As shown in FIGS. 1 and 2, each short side wall portion 4 extends along the short side wall portion 4 and is juxtaposed on the outer surface side of the short side wall portion 4. A handle 21 is provided that can be displaced between a posture and a use posture that protrudes outward from the short side wall 4 and extends in a direction intersecting the short side wall 4. Yes. As shown in FIGS. 8 and 9, the handle 21 includes a gripping portion 23 that can be gripped by an operator, and a pair of extending portions that extend from both ends of the gripping portion 23 in a direction substantially orthogonal to the gripping portion 23. A generally U-shaped handle portion 22 having a projecting portion 24, and a pair of hinge portions 25 projecting toward the inside of the handle portion 22 so as to be close to each other from the respective distal end portions of the pair of extending portions 24; It has. Note that the handle 21 of the present embodiment is made of polypropylene.

  On the other hand, as shown in FIG. 6, a bearing portion 27 that rotatably supports each hinge portion 25 is provided on the outer surface side of the short side wall portion 4. As shown in FIGS. 1 and 10, the handle 21 of the present embodiment is configured such that the extension portion 24 extends downward from the hinge portion 25 when the handle 21 is in a non-use posture. In addition, by holding the grip portion 23 of the handle 21 in a non-use posture and pulling it outward, the handle 21 is rotated and displaced upward about the hinge portion 25 as shown in FIGS. Will be.

  As shown in FIG. 6, the handle 21 is provided on the outer surface side of the short side wall 4 when the handle 21 is in a use posture extending substantially horizontally just above the pair of hinges 25. A stopper portion 28 is provided to abut against the upper surface of the. Thereby, in this embodiment, it is comprised so that the extension part 24 can be displaced to the position extended substantially orthogonally with respect to the short side wall part 4 (it extends substantially horizontally). Furthermore, in the present embodiment, a position directly below the short side hinge portion 29 provided on the upper side portion of the short side wall portion 4 and rotatably connected to the short side frame constituting portion 18 of the upper frame 5. In FIG. 11, a stopper portion 28 is provided. As shown in FIG. 11 and the like, the outer surface side of the stopper portion 28 is covered with the upper frame 5. That is, the bearing portion 27 is installed in the uppermost portion of the short side wall portion 4 in a range where the bearing portion 27 can be installed, and the handle 21 does not come into contact with the upper frame 5 by providing the stopper portion 28. It is configured as follows. As shown in FIGS. 6 and 7, the short side wall 4 of the present embodiment has a bilaterally symmetric shape, and the pair of short side walls 4 have the same shape.

  Moreover, the outer surface side of the short side wall portion 4 has a shape in which the inner peripheral side portion where the handle 21 is provided is recessed rather than the outer peripheral edge portion, as shown in FIG. Most of the handle 21 in the non-use posture is set within the range of the thickness of the short side wall portion 4. Further, the handle 21 in the non-use posture protrudes slightly outward from the short side wall 4, but is on the inner peripheral side of the outer peripheral surface (side surface of the folding container 1) of the bottom wall portion 2 and the upper frame 5. To fit in. In other words, if the handle 21 is in a non-use posture, the handle 1 can be used even when the folding container 1 in an assembled state is brought into contact with the wall surface of the installation space or the folding containers 1 are installed side by side. 21 does not contact the wall surface or the adjacent folding container 1.

  Furthermore, an introduction recess 31 is formed on the outer surface side of the short side wall portion 4 of the present embodiment, corresponding to the grip portion 23 of the handle 21 in the non-use posture. As a result, a gap is formed between the grip portion 23 of the handle 21 in the non-use posture and the short side wall portion 4. And a fingertip can be inserted in the introduction recessed part 31, and a fingertip can be hung on the back surface side (opposite surface with the short side wall part 4) of the holding part 23. FIG. In particular, the introduction recess 31 of the present embodiment is formed from the lower position to the upper position of the grip portion 23 of the handle 21 in the non-use posture. A fingertip can be inserted (see FIG. 10). The lateral width of the introduction recess 31 is substantially the same as the distance between the pair of extension portions 24 of the handle, and the handle 21 is arranged so that the introduction recess 31 is located between the pair of extension portions 24. ing.

  In addition, as shown in FIG. 10, the grip portion 23 of the present embodiment is formed with an inclined portion 32 that extends obliquely from the lower surface when the handle 21 is in the non-use posture to the surface on the short side wall portion 4 side. Has been. As described above, the inclined portion 32 that extends upwardly toward the inner side of the folding container 1 (on the short side wall portion 4 side) is formed on the lower surface of the gripping portion 23, so that the non-use posture is achieved. It is easy to put a fingertip on the back side of the grip portion 23 from below the grip portion 23 of a handle 21. In this embodiment, the introduction recess 31 and the inclined portion 32 constitute a gap forming means.

  Moreover, as shown in FIG. 6, FIG. 12, etc., the site | part corresponding to the front-end | tip part (connection part with the hinge part 25 of the extension part 24) of the short side wall part 4 in the short side wall part 4. As shown in FIG. Is provided with a holding projection 34 projecting outward. On the other hand, as shown in FIG. 8, FIG. 9, FIG. 12, etc., the distal end portion of the extension portion 24 is held when the handle 21 is rotated and displaced about 48 degrees outward from the non-use posture. A holding piece portion 35 that abuts on the upper surface side of the protrusion 34 is provided. Then, as shown in FIG. 13, when folding the folding container 1, if the short side wall portion 4 is flipped up and displaced to the folding position side, the folding container 1 is pivotally attached to the outer surface side of the short side wall portion 4. The handle 21 hangs down from the short side wall 4 due to its own weight, but when the handle 21 is rotated and displaced outward from the short side wall 4 by about 48 degrees, the handle 21 and the holding protrusion 34 are held. The one part 35 abuts, and further rotation displacement of the handle 21 is restricted.

  Further, in a state where the holding projection 34 and the holding piece portion 35 are in contact with each other, that is, in a state where further displacement of the handle 21 to the use posture side is limited, By applying a force of a specified amount or more toward the use posture side, the holding piece portion 35 gets over the holding projection 34 while being elastically deformed. Thereby, as shown in FIG. 11, the handle 21 can be displaced until it comes into contact with the stopper portion 28. In the present embodiment, the holding projection 34 and the holding piece 35 constitute a range limiting unit.

  As described above in detail, according to the present embodiment, the handle 21 is arranged in a non-use posture in which the handle 21 as a handle is juxtaposed on the outer surface side of the short side wall portion 4, so that the handle 21 is short side wall. It is possible to prevent the portion 4 from protruding outward as much as possible (in this example, the handle 21 is accommodated on the inner peripheral side of the outer peripheral edges of the bottom wall portion 2 and the upper frame 5). Therefore, when the folding container 1 is assembled in a box shape and the handle 21 is not used, an extra storage space is required due to the presence of the handle 21, or the handle 21 itself is easily damaged. It is possible to prevent such a situation. Furthermore, even when the folding container 1 is folded, the situation where the handle 21 interferes to hinder the folding operation of the short side wall 4 or the height of the folding container 1 in the folded state is prevented. can do.

  Moreover, the handle 21 should just be a shape which is easy to hold | grip by pulling out the handle 21 in a non-use posture from the short side wall part 4 to a use posture. For this reason, the short side wall including the handle 21 in the non-use posture is used even under the condition that the thickness of the short side wall 4 is relatively thin and the handle 21 cannot be secured so much. The handle 21 can be shaped so as to be easily gripped in the use posture while being able to be stored as compactly as possible with respect to the thickness of the portion 4. Therefore, it is possible to reduce the thickness of the short side wall portion 4 while ensuring the ease of holding the handle 21 (easy to apply force) and, in turn, stabilizing the state in which the handle 21 is held and the folding container 1 is held. be able to. Then, by reducing the thickness of the short side wall portion 4 and the like in this way, the height of the folding container 1 in the folded state can be made as low as possible, and weight saving, resource saving, cost reduction, etc. can be achieved. can do.

  Furthermore, since the handle 21 is configured to be displaced, the handle 21 is displaced following the direction in which the force is applied. Therefore, not only can the handle 21 be put on the handle 21 and lifted, but also the operation of pulling (pulling) to the side can be performed relatively smoothly.

  In addition, there is no need to form an opening penetrating in the thickness direction with respect to the short side wall portion 4 or the like so as to form a handle. Thus, it is possible to reliably avoid a situation in which foreign matters such as dust and small animals enter the folding container 1. Therefore, the hygiene management etc. of the articles accommodated in the folding container 1 can be performed more reliably.

  Moreover, also when assembling the folding container 1, the handle | steering-wheel 21 can be held and the short side wall part 4 can be caused, and the improvement of assembly workability | operativity can be aimed at. Furthermore, when the short side wall 4 is unintentionally displaced to the folding position side from the assembled state of the folding container 1 as shown in FIG. 17, the handle 21 is pulled to shorten it. By reassembling the side wall 4, it can be returned to the assembled state relatively easily. Therefore, in order to press the short side wall portion 4 that has been displaced to the folding position side from the inner surface side and to rebuild it, the lid member 7 is removed, the contents are taken out from the folding container 1, or stacked on the upper side. When the folding container 1 is present, it is possible to avoid a situation in which the upper folding container 1 must be lowered.

  Further, in a state where the operator does not apply force to the handle 21, if the handle 21 in the non-use posture is rotated and displaced outward by about 48 degrees with respect to the short side wall 4, the short side wall The holding projection 34 protruding outward from the portion 4 and the holding piece 35 provided at the distal end of the extending portion 24 of the handle 21 come into contact with each other, so that further rotational displacement of the handle 21 is restricted. It has become. For this reason, the posture of the handle 21 in a state where the operator does not apply force to the handle 21 can be restricted. Accordingly, when the folding container 1 is folded, the handle 21 is unintentionally displaced in a posture that hinders the operation of the short side wall 4, and it becomes difficult to fold the folding container 1. Can be prevented. Further, by applying a force of a specified amount or more toward the use posture side from the state in which the rotational displacement of the handle 21 is regulated, the handle 21 is brought into contact with the stopper portion 28 (short side wall). (To a range that forms an angle of about 90 degrees with respect to the portion 4). Accordingly, the posture of the handle 21 can be changed more flexibly than the configuration in which the handle 21 is rotated and displaced only to the extent that the handle 21 extends outward and downward. A sense of stability when carrying 1 can be improved.

  In particular, the handle 21 of the present embodiment is not held in a non-use posture, and the angle with respect to the short side wall portion 4 is about 48 degrees at which the holding piece portion 35 and the holding projection 34 abut. Until it becomes, it will be rotationally displaced relatively freely without being regulated. For this reason, the handle 21 in the non-use posture extending along the short side wall portion 4 can be pulled out without applying force. Accordingly, it is possible to improve the operability when the handle 21 in the non-use posture is pulled out to the use posture side.

  Further, an introduction recess 31 is formed on the outer surface side of the short side wall portion 4 corresponding to the grip portion 23 of the handle 21 in the non-use posture. Thereby, the clearance gap which can let an operator's fingertip etc. penetrate | invade between the holding part 23 of the handle | steering-wheel 21 in a non-use posture, and the short side wall part 4 can be formed. Therefore, it becomes easier to put a finger on the grip portion 23 of the handle 21 in the non-use posture, the handle 21 in the non-use posture is pulled out to the use posture side, or the handle 21 in the use posture is put into the non-use posture. The workability at the time of storing can be improved. In particular, since the inclined portion 32 is formed in the portion on the short side wall portion 4 side in the surface of the handle 21 outer peripheral side of the grip portion 23 which is the lower surface of the handle 21 in the non-use posture, such an operational effect is further increased. It will be played more prominently.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above-described embodiment, the folding container 1 includes the upper frame 5 and flips the short side wall portion 4 upward, and folds the middle portion in the vertical direction of the long side wall portion 3 to be bent inward. Although it is embodied in a flip-up type folding container 1 that can be used, there is no upper frame 5 and the lower side portion of the long side wall portion 3 and the short side wall portion 4 rotate with respect to the bottom wall portion 2. The present invention may be applied to an inversion type folding container that is connected so that the long side wall 3 and the short side wall 4 can be folded over the bottom wall 2. When adopting the configuration, it is desirable that the handle 21 in the non-use posture is configured to be accommodated within the thickness range of the side wall portion on which the handle 21 is provided. In this case, when the folding container 1 is in the assembled state, an extra installation space is required by the handle 21, or the height of the folding container 1 in the folded state is increased due to the provision of the handle 21. You can avoid situations such as trapping.

  Moreover, in the said embodiment, although the handle | steering-wheel 21 is provided in a pair of short side wall part 4, it does not specifically limit about the number of the side wall part or handle | steering-wheel 21 in which the handle | steering-wheel 21 is provided, At least 1 What is necessary is just to be provided in the side wall part. However, by providing the handle 21 on the pair of opposite side wall portions, the folding container 1 can be lifted by holding the handle 21 and the ease of carrying can be improved. The shape of the handle 21 is not particularly limited. For example, the handle portion 22 may be configured in a substantially C shape so that the boundary between the grip portion 23 and the pair of extending portions 24 is difficult to understand. Alternatively, the extending portion 24 of the handle portion 22 may be a single, and may be a T-shaped handle portion 22 having a grip portion 23 extending in a direction substantially orthogonal to the tip thereof, or on the handle 21 side. In addition, a shaft hole may be formed, and a shaft portion inserted into the shaft hole may protrude from the short side wall portion 4 side.

  (B) In the said embodiment, when the folding container 1 exists in a folding state, it is comprised so that the handle 21 provided in the long side wall part 3 and the short side wall part 4 may not contact | abut. (See FIG. 4), for example, the longer side wall 3 is configured to be higher, or the handle 21 is configured to have a wider width. You may comprise so that the side wall part 3 may be located. In this case, it is desirable to provide range limiting means (holding protrusion 34 and holding piece 35) so that the folding operation of the long side wall 3 is not hindered by the handle 21.

  Further, when such a configuration is adopted, the pair of extending portions 24 of the handle 21 may be inclined toward the center portion in the longitudinal direction of the grip portion 23 so as to be close to each other toward the grip portion 23 side. In this case, the angle of the handle 21 hanging from the short side wall 4 with respect to the short side wall 4 or the bottom wall 2 in a state where the short side wall 4 is in the folded position as in the above embodiment. When the long side wall portion 3 is folded, the extended portion 24 of the handle 21 is connected to the lower wall portion 11 and the upper wall portion 12 when the long side wall portion 3 is folded. The long side wall portion 3 can be configured to slide into the lower side of the handle 21 relatively smoothly. Therefore, the folding workability can be improved.

  (C) In the above embodiment, the bearing portion 27 that pivotally supports the handle 21 is formed at the uppermost portion of the short side wall portion 4 in the range where the bearing portion 27 can be formed. The extending portion 24 is configured to extend downward from the hinge portion 25. However, as shown in FIGS. 18 to 21, in the handle 21 in the non-use posture, the extending portion 24 is located above the hinge portion 25. The grip portion 23 of the handle 21 in the non-use posture may be configured to be positioned below the upper side portion of the short side wall portion 4.

  In this case, by pulling the handle 21 in the non-use posture slightly outward, the use posture can be obtained in which the extension portion 24 extends obliquely upward and outward from the hinge portion 25. When the folding container 1 is lifted by grasping the gripping part 23 of the handle 21 in such a use posture, it is positioned above the gripping part 23 of the handle 21 on the side surface of the folding container 1 by a wrist or an arm. The part to be held (in this embodiment, the outer peripheral surface of the upper frame 5) can be held. Therefore, the folding container 1 can be lifted in a more stable state.

  Further, for example, in the configuration in which the extension portion 24 extends downward from the hinge portion 25 in the non-use posture of the handle 21 as in the above embodiment, the short side wall portion 4 is more than the hinge portion 25. In addition to requiring a space for accommodating the handle 21 in a non-use posture at the lower position side by side with the side wall 4 on the short side, the handle 21 is tilted outward and upward as described above. For this purpose, it is necessary to rotate the handle 21 by 90 degrees or more. For this reason, when the height of the folding container 1 is not so high compared to the vertical width (height) of the handle 21 in the non-use posture, the handle 21 is rotated to the use posture in which the handle 21 is inclined outward and upward. When it is moved and displaced, the gripping part 23 is positioned above the folding container 1 or above the upper side, and as described above, the side surface of the folding container 1 cannot be held by a wrist or the like. .

  In this respect, according to the present embodiment example shown in FIG. 18 and the like, the extension portion 24 extends upward from the hinge portion 25 when the handle 21 is in the non-use posture. The height position of the part 25 can be set to a low position of the short side wall part 4 (possible in the vicinity of the lower side part of the short side wall part 4), even if the folding container 1 is not so high, It is possible to carry the handle 21 while holding the side surface of the folding container 1 with a wrist or the like as a use posture in which the handle 21 is inclined upward and outward. In particular, as shown in FIG. 22, when the folding containers 1 are lifted in a stacked state, the short side wall portion 4 of the folding container 1 positioned at the lowermost side and the folding containers 1 positioned above the folding container 1 Since the wrist and the arm can be continuously applied and held over the short side wall portion 4, it is possible to more reliably prevent the positional deviation between the folding containers 1 in the left-right direction. Therefore, it is possible to further stabilize the carrying state. In addition, by adopting the configuration of this embodiment, the load on the hinge portion 25 and the like of the handle 21 when the folding container 1 is transported by applying an obliquely upward force to the grip portion 23 of the handle 21 is reduced. be able to.

  In the case where the extending portion 24 of the handle 21 in the non-use posture is substantially suspended from the hinge portion 25 as in the above embodiment, a configuration in which the handle 21 is completely held in the non-use posture is adopted. Even if it is not, it is easy to maintain the non-use posture of the handle 21.

  (D) In the above embodiment, in a state where no force is applied to the handle 21, if the handle 21 in the non-use posture is up to about 48 degrees on the use posture side as the short side wall 4 tilts, Further, the holding piece 35 is configured to be movable, and the holding piece 35 is in contact with the holding projection 34 so that the displacement to the use posture side is restricted and the hand 21 is put on the use posture side to apply force. Thus, the extending portion 24 is configured to be rotatable and displaceable until it extends substantially horizontally (in a direction substantially orthogonal to the short side wall portion 4), but is not particularly limited to such a configuration.

  For example, it is good also as providing the latching | locking part which latches the handle | steering_wheel 21 in a non-use posture in the outer surface side of the short side wall part 4. FIG. In this case, the handle 21 is held in a non-use posture. When the handle 21 is not used, the handle 21 protrudes outward from the side surface of the folding container 1 unintentionally, and is transported or stored. Thus, it is possible to more reliably prevent such a situation that the handle 21 itself is easily damaged. In this case, the locking portion constitutes the range limiting means. Further, for example, the outer peripheral surface of the hinge portion 25 of the handle 21 and the bearing portion 27 that pivotally supports the hinge portion 25 are always in a pressure contact state, so that the handle 21 can be maintained in a desired posture by frictional force. It may be configured. In this case, the hinge portion 25 and the bearing portion 27 of the handle 21 that are in pressure contact constitute a range limiting means. Note that the range limiting means can be omitted.

  In the example of the above (c), as shown in FIGS. 20 to 24, the holding projection 34 is formed on the inner peripheral side of the bearing portion 27 of the short side wall portion 4, and FIGS. As shown in FIGS. 25 and 26, the hinge portion 25 of the handle 21 that is pivotally supported by the bearing portion 27 is formed in a substantially elliptical cross section that is wide in the longitudinal direction of the extending portion 24. As shown in FIG. 20, in the non-use posture of the handle 21, the hinge part 25 having an elliptical cross section is pressed against the holding protrusion 34 and held in the non-use posture. Further, by applying a force of a specified amount or more outwardly to the handle 21 in the non-use posture, the hinge portion 25 gets over the holding projection 34 as shown in FIG. 21, and the handle 21 is brought into the use posture. And can be displaced.

  In addition, for example, the handle 21 may be configured to be rotatable by 90 degrees or more. Further, the grip portion 23 of the handle 21 can be positioned above the hinge portion 25, the lower side portion of the upper frame 5, the upper side portion of the short side wall portion 4, or the upper side portion of the upper frame 5. May be. Furthermore, in the said embodiment, although the handle | steering-wheel 21 is comprised so that rotation displacement may be carried out, you may comprise between a use attitude | position and a non-use attitude | position by sliding displacement. For example, the handle 21 is configured to be displaceable in the thickness direction of the short side wall 4, and between the use position where a gap is formed between the short side wall 4 and a non-use position where the gap is smaller than that. May be configured to be displaceable. Further, for example, the handle 21 is configured to be slidable along the short side wall portion 4, and the handle 21 is accommodated within the area of the short side wall portion 4, and at least the gripping portion 23 is provided. The folding container 1 may be configured to be displaceable from the side of the folding container 1 so as to protrude upward or to the left and right sides (for example, the handle 21 may be vertically moved while being in the non-use posture of (C) above). It may be configured to be slidable in the direction).

  However, when the handle 21 protrudes above the upper frame 5 (for example, the handle 21 in a non-use posture is rotated by about 180 degrees so that the handle 21 extends along the height direction of the short side wall 4). In the case where the handle 21 is extended), it is necessary to form a recess (notch) in the upper frame 5 and the strength of the upper frame 5 and the like may be reduced. Therefore, the movable range of the handle 21 is the folding container 1. It is desirable that the height be within the range. Further, the handle 21 is configured such that the extending portion 24 extends downward from the hinge portion 25 along the short side wall portion 4 and the extending portion 24 extends upward from the hinge portion 25 along the short side wall portion 4. It is configured so that it can be pivotally displaced between the extended posture and the handle 21 is within the range of the height of the short side wall 4 regardless of whether the handle 21 extends vertically along the short side wall 4. You may apply to the folding container 1 with comparatively high height which can be accommodated.

  (E) In the above embodiment, the introduction recess 31 is formed in the outer surface side of the short side wall 4 at the site corresponding to the grip 23 of the handle 21 in the non-use posture. The introduction recess 31 may be formed in a portion corresponding to the above. In this case, it becomes easy to perform an operation of grasping the grip portion 23 after the handle 21 is pulled to the use posture side to some extent by grasping the extending portion 24 of the handle 21 in the non-use posture. In addition, if the introduction recessed part 31 is formed so that the whole extension part 24 and the holding part 23 are completely accommodated, there is a gap between the handle 21 and the short side wall part 4 in the non-use posture. Since it becomes impossible, the introduction recessed part 31 shall be provided corresponding to a part of the handle part 22 of the handle 21.

  Further, the inclined portion 32 of the above embodiment is formed on the lower surface side of the grip portion 23 of the handle 21 in the non-use posture, but instead of or in addition to this configuration, on the upper surface side of the grip portion 23. It may be formed. In addition, the inclined portion 32 of the above-described embodiment is formed only in the portion on the short side wall portion 4 side in the lower surface of the grip portion 23, and is configured to be inclined upward toward the inside of the container as a whole. May be.

  Moreover, in the said embodiment, in order to make it easy to put a finger | toe on the handle 21 in a non-use posture and to pull out to the use posture side, the introduction recessed part 31 is formed in the short side wall part 4, and the holding part of the handle 21 Although the inclined part 32 is formed in 23, it is good also as providing either one, and both can also be abbreviate | omitted. Further, instead of or in addition to the introduction concave portion 31 and the inclined portion 32, the short side wall portion 4 protrudes from a part of the handle portion 22 of the handle 21 in the non-use posture toward the short side wall portion 4 side. It is good also as forming a clearance gap between the handle | steering-wheel 21 in a non-use attitude | position and the short side wall part 4 by providing the convex part which can contact | abut.

  (F) In the above embodiment, the folding container 1 and the lid member 7 are made of polypropylene, but may be made of other resin materials such as polyethylene, PET, and polyamide. Also, the material of the handle 21 is not particularly limited. For example, the handle 21 may be made of a metal material so that sufficient strength can be obtained even if the thickness is not so much.
