Description

[Technical field]

[0001] The present invention relates to a container having a handle. [Background technology]

[0002] When carrying items to be purchased at a store, a shopping basket provided by the store may be used. In recent years, when carrying purchased items home, people may use their own shopping basket instead of a disposable plastic bag.

[0003] As an example of such a shopping basket, Patent Document 1 discloses a shopping basket having a basket body that is formed in a roughly rectangular shape, has an open top and a network of multiple slit holes on the peripheral wall, and has a handle on the edge of the opening for carrying.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 9-039953 Summary of the Invention [Problem to be solved by the invention]

[0005] A shopping basket can be carried by hanging a hand or arm on the handle of the above-mentioned conventional technology. However, the handle is rotatably attached, and there is a risk of noise caused by collision between the shopping basket and the handle, or damage caused by the handle coming into contact with other structures (such as a wall). When carrying a conventional shopping basket without any items inside, the user may grab the area near the short side of the rectangular opening edge of the basket and make the long side vertical. In this case, the handle part for carrying the shopping basket rotatably attached to the shopping basket may not be aligned with the opening edge of the shopping basket, but may fall in a direction perpendicular to the opening edge, or may rotate 180 degrees and hit the opposite side of the opening edge.

[0006] One aspect of the present invention aims to provide a container equipped with a handle that does not produce noise caused by the handle rotating inadvertently and colliding with the edge of the container (basket), or be damaged by contact with structures, etc. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, a container according to one embodiment of the present invention is a container having an opening at an upper portion, and includes a handle portion connected to the container near the opening, which is displaced by rotation between a first position in which it lies flat along the edge of the opening and a second position in which it stands up from the edge and the container can be carried using the stood up portion, a grip portion extending laterally from the outer surface of the container, and a rotation restriction portion which restricts the rotation of the handle portion from the first position to the second position. Effect of the Invention

[0008] According to one aspect of the present invention, a container can be realized that does not cause noise caused by the handle accidentally rotating and colliding with the edge of the container (basket), and does not cause damage due to contact with structures, etc. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The container according to one embodiment of the present invention will be described in detail below. The container according to this embodiment has an appearance similar to a shopping basket used in a store, etc., and as one example, the container can be realized in a form in which an item can be put and carried in a storage space defined by the inner surface of the container, and a shopping basket from the store can be placed on top of the storage space.

[0011] In particular, the container of this embodiment is configured such that the handle attached to the container does not rotate inadvertently. "Does not rotate inadvertently" means that the handle does not rotate when not being used to carry the container. Examples of such cases include a case where an empty (non-containing) container is carried in a tilted position with the opening of the container facing sideways, and a case where a container containing an item is turned upside down to remove the item.

[0012] An example of an embodiment that realizes this configuration will be described below. In the following, the components will be described as "upper" and "lower". In this specification, when the container of this embodiment is placed with the bottom plate portion horizontal to a horizontal plane, the direction toward the zenith along the vertical direction is defined as "upper (direction)" and the opposite direction is defined as "lower (direction)", and these definitions will be used. In addition, each figure shows three-dimensional coordinate axes of XYZ, where the direction toward the zenith along the vertical direction is defined as the Z direction and the horizontal plane is defined as the XY plane.

[0013] FIG. 1 is an external perspective view of a container according to this embodiment, showing a state in which a handle portion provided on the container is in a first position. Here, the "first position" refers to a position in which the handle portion is inclined so as to follow the edge of the opening of the container. FIG. 2 is an external perspective view of a container according to this embodiment, showing a state in which the handle portion provided on the container is in a second position. Here, the "second position" refers to a position in which the handle portion stands up from the edge of the opening of the container, and the handle portion in this position functions as a carrying portion when carrying the container of this embodiment.

[0014] The container 1 has an opening 1a at the top, and includes a handle portion 400 connected to the container 1 near the opening 1a. The handle portion 400 is displaced by rotation between a first position in which it is laid down along the edge of the opening 1a, and a second position in which it stands up from the edge and the container 1 can be hung using the standing part. The container 1 further includes a grip portion 500 extending laterally from the outer surface of the container 1. The container 1 further includes a rotation restriction portion 600 that restricts the rotation of the handle portion 400 from the first position to the second position.

[0015] Although the detailed configuration will be described later, the container 1 defines a storage space by a bottom plate portion 110 and a side wall portion consisting of a first side wall portion 120 and a second side wall portion 200. The upper end of the side wall portion (specifically, the second side wall portion 200) defines the edge of the opening 1a. In short, this opening 1a communicates with the storage space inside the container 1.

[0016] The bottom plate 110 is configured in a generally rectangular plate shape. The side wall extending upward from the peripheral edge of the bottom plate 110 includes two pairs of side walls that face each other across the storage space for the container 1. Specifically, the two pairs of side walls are made up of a pair of side walls 200A, 200A' extending upward from each of a pair of long sides of the peripheral edge of the rectangular bottom plate 110, and a pair of side walls 200B, 200B' extending upward from each of a pair of short sides of the peripheral edge.

[0017] The handle portion 400 is connected to one of the two pairs of side wall portions 200A, 200A'. Specifically, when the handle portion 400 is in the first position, it is along the upper end of the other of the two pairs of side wall portions 200B, 200B'. Two handle portions 400 are provided on the container 1, and when the container 1 is in the first position, one handle portion 400 is arranged along the side wall portion 200B and the other handle portion 400 is arranged along the side wall portion 200B'.

[0018] The configuration of the handle portion 400 will be further described with reference to FIG. 3. Note that the two handle portions 400 have the same configuration, and therefore, one handle portion 400 will be described below. FIG. 3 is a perspective view of the handle portion 400. The handle portion 400 has a shape formed by, for example, three consecutive sides of the four sides of a rectangle, and both end portions 401 are connected to the side wall portions 200A, 200A'. In detail, regarding this connection, the both end portions 401 are connected to the rotation shaft portion 270 (FIG. 7) protruding along the virtual axis C provided on the side wall portions 200A, 200A' side so as to be rotatable about the virtual axis C shown in FIG. 1 and FIG. 2 as a rotation axis. As a result, the handle portion 400 rotates between a first position shown in FIG. 1 and a second position shown in FIG. 2 about the virtual axis C shown in FIG. 1 and FIG. 2 as a rotation axis.

[0019] One end 401 of each of the two handle portions 400 is disposed adjacent to each other along the edge of the side wall portion 200A. The other end 401 is disposed adjacent to each other along the edge of the side wall portion 200A'. Each of the handle portions 400 rotates about its own imaginary axis C. When an operator rotates the handle portions 400 to take the second position shown in FIG. 2, the two handle portions 400 function as carrying portions of the container 1, and the operator can place his / her hands or arms on them.

[0020] Further, in the vicinity of each of the two end portions 401 of the handle portion 400, a locking body 601 is provided.

[0021] The locking body 601 locks a locked body 602 provided near a flange portion 250 provided on the side wall portion 200 as described below. The locking of the locked body 602 by the locking body 601 restricts rotation of the handle portion 400 about a virtual axis C. In this embodiment, the locking body 601 and the locked body 602 constitute a rotation restricting portion 600.

[0022] Before describing the regulation of rotation in detail, the configuration of the container 1 will be described below.

[0023] The container 1 can change its shape to a compact form when no article is placed in the storage space (when not stored). Furthermore, the container is configured so that the shape does not change inadvertently (does not return to its original state) when in this compact form. An example of an embodiment that realizes this configuration will be described below.

[0024] 4 is an exploded perspective view of the container 1, with each component disassembled, as viewed from the upper side of the container 1. The container 1 includes a bottom wall component 100 including a substantially plate-shaped bottom plate portion 110 and a first side wall portion 120 extending upward from the peripheral portion of the bottom plate portion 110, and a second side wall portion 200 that is cylindrical and telescopically expands and contracts relative to the bottom wall component 100. The container 1 further includes a belt member 300 (regulation mechanism) that connects the bottom wall component 100 and the second side wall portion 200, and that regulates the contraction of the second side wall portion 200 when the second side wall portion 200 is in an expanded state relative to the bottom wall component 100 and regulates the expansion of the second side wall portion 200 when the second side wall portion 200 is in a contracted state relative to the bottom wall component 100.

[0025] In short, the side wall of the container 1 is configured to telescopically contract relative to the bottom plate 110 to reduce the size of the storage portion of the container 1, and to telescopically expand relative to the bottom plate 110 to return to the original size, and the movement of the side wall accompanying the change in size is regulated by the belt member 300. Each configuration will be described in further detail.

[0026] The bottom wall constituent part 100 is a box-shaped structure including a substantially plate-shaped bottom plate part 110 and a first side wall part 120 extending upward from the peripheral part of the bottom plate part 110. The container 1 has the same specifications as a so-called shopping basket, and therefore a large number of through holes are provided in the bottom wall constituent part 100. Furthermore, the bottom wall constituent part 100 is provided with a first attachment part 103 and a second attachment part 105.

[0027] The first attachment portion 103 is a portion that is locked by the bottom attachment portion 305 of the belt member 300. The first attachment portion 103 is provided at the boundary portion between the bottom plate portion 110 and the first side wall portion 120. The first attachment portion 103 is provided at the middle position of a pair of short edges of the bottom plate portion 110 having a rectangular peripheral side. Each first attachment portion 103 is a hole that penetrates from the inner surface to the outer surface of the bottom wall constituent portion 100, and the bottom attachment portion 305 of the belt member 300 can be inserted and fitted into it. The bottom attachment portions 305 (FIG. 5) of different belt members 300 are locked to one first attachment portion 103 and the other first attachment portion 103.

[0028] Two second attachment portions 105 are arranged side by side along a pair of long edges of the bottom plate portion 110 having rectangular peripheral sides in the central portion of the bottom plate portion 110. Bottom attachment portions 305 (FIG. 5) of separate belt members 300 are engaged with one second attachment portion 105 and the other second attachment portion 105.

[0029] The first attachment part 103 and the second attachment part 105 are engaged with the bottom attachment part 305 of the belt member 300 when the container 1 has a different shape. Specifically, the bottom attachment part 305 is engaged with the first attachment part 103 when the container 1 is in an assembled state, and is engaged with the second attachment part 105 when the container 1 is in a non-assembled state. Here, the "assembled state" refers to a state in which a storage space for storing an item or a shopping basket is assembled, and a second side wall part 200, which will be described later, is assembled to the bottom wall component part 100. FIGS. 1 and 2 are external perspective views of the container 1 when it is in an assembled state. In contrast, the "non-assembled state" refers to a state in which the side wall part (second side wall part 200) of the container 1 is contracted, and there is no storage space. This shape is taken when the container 1 itself is carried or stored. FIG. 5 shows an external perspective view of the container 1 when it is in a non-assembled state.

[0030] The top surface of the bottom plate portion 110 is further provided with a rail portion 107 (FIGS. 4 and 5).

[0031] The rail portion 107 extends from one second attached portion 105 to the first attached portion 103 provided on the short edge of the rectangular bottom plate portion 110 to which the second attached portion 105 is closest. The rail portion 107 also extends from the other second attached portion 105 to the first attached portion 103 provided on the short edge of the rectangular bottom plate portion 110 to which the second attached portion 105 is closest.

[0032] As shown in FIG. 4, the first side wall portion 120 corresponds to a portion rising from the peripheral portion of the bottom plate portion 110 having a rectangular peripheral side. The first side wall portion 120 rises approximately perpendicular to the upper surface of the bottom plate portion 110. In addition to a large number of through holes, the first side wall portion 120 is formed with a slit portion 120b extending vertically along the wall surface. A convex portion 203a provided on the lower portion of the inner surface of the second side wall portion 200 is slidably fitted into the slit portion 120b. This enables the second side wall portion 200 to telescopically expand and contract with respect to the bottom wall constituent portion 100. As shown in FIG. 4, three slit portions 120b are provided on each of the first side wall portions 120 provided on a pair of long edges of the bottom plate portion 110 having a rectangular peripheral side. However, the number is not limited to this.

[0033] 4, the container 1 has a second side wall portion 200 configured to have a plurality of stages, specifically including a second side wall portion upper stage 201 located at the top stage in an assembled state, a second side wall portion middle stage 202 located at the middle stage, and a second side wall portion lower stage 203 located at the bottom stage. The aforementioned convex portion 203a is provided on the inner surface of the second side wall portion lower stage 203, and is slidably fitted into the slit portion 120b of the first side wall portion 120.

[0034] Similarly to the slits 120b, slits 203b, which are slits extending vertically along the wall surface, are formed in multiple locations in the second side wall lower stage 203. Convex middle stages 202a, which are provided on the inner surface of the second side wall middle stage 202 and are similar to the convex portion 203a described above, are slidably fitted into these slit lower stages 203b.

[0035] Furthermore, slit middle stages 202b, which are slits extending vertically along the wall surface like slits 120b, are formed in multiple locations in second side wall middle stage 202. Convex upper stages 201a provided on the inner surface of second side wall upper stage 201, similar to convex portion 203a described above, are slidably fitted into these slit middle stages 202b.

[0036] By lowering these convex portions 203a, 202a, 201a relative to the slit portions 120b, 203b, 202b, the second side wall portion 200 in the assembled state shown in Fig. 2 becomes the state (unassembled state) shown in Fig. 1 in which it is shortened relative to the bottom wall constituent portion 100. Conversely, by raising the convex portions 203a, 202a, 201a relative to the slit portions 120b, 203b, 202b from the unassembled state shown in Fig. 1, the second side wall portion 200 becomes the assembled state in which it stands up and extends relative to the bottom wall constituent portion 100 as shown in Fig. 2.

[0037] The second side wall portion 200 that telescopically expands and contracts in this manner is restricted in its expansion and contraction motion by the belt member 300.

[0038] The belt member 300 is belt-shaped and has a predetermined length in the longitudinal direction, with a side wall attachment portion 303 provided at one end 301 and a bottom attachment portion 305 provided at the other end 302 .

[0039] The side wall attachment part 303 has a structure that allows it to be attached to the upper end of the second side wall part 200, specifically, to the second side wall part upper stage 201. When the side wall attachment part 303 is inserted into the side wall attached part 204 and attached, it cannot be easily removed, and one end part 301 of the belt member 300 can be fixed to the second side wall part upper stage 201.

[0040] Bottom mounting portion 305 is provided on the underside of the other end portion 302. Specifically, bottom mounting portion 305 is a locking shaft portion protruding from the underside of the other end portion 302. Bottom mounting portion 305 can be inserted into the first mounting portion 103 and the second mounting portion 105 of bottom wall constituent portion 100 described above. In the assembled state, bottom mounting portion 305 is inserted into first mounting portion 103.

[0041] When the bottom mounting portion 305 is engaged with the first mounting portion 103, as shown in Figures 1 and 2, the belt member 300 extends upward and has a predetermined rigidity, thereby preventing the upwardly extended second side wall portion 200 from telescopically contracting under its own weight.

[0042] Here, the bottom mounting portion 305 attached to the first mounting portion 103 can be removed from the first mounting portion 103 relatively easily by the operator moving it with his or her fingers, thereby releasing the engaged state between the bottom mounting portion 305 and the first mounting portion 103.

[0043] Here, the installation mode of the belt member 300 will be described with reference to Fig. 1 and Fig. 4. As shown in Fig. 4, the first side wall 120 is provided with a first insertion portion 122 through which the belt member 300 is inserted. In addition, the second side wall lower stage 203 and the second side wall middle stage 202 of the second side wall 200 are each provided with a second insertion portion 222 through which the belt member 300 is inserted. The belt member 300 is formed to have approximately the same width as the first insertion portion 122 and the second insertion portion 222, and by inserting the belt member 300 into the first insertion portion 122 and the second insertion portion 222, the displacement of the belt member 300 in the width direction is restricted by the edges of the first insertion portion 122 and the second insertion portion 222, and rattling is suppressed. Furthermore, since the belt member 300 is inserted through the first insertion portion 122 and the second insertion portion 222, the belt member 300 can be stably operated when moving the belt member 300 in association with the expansion and contraction of the second side wall portion 200.

[0044] On the other hand, when the container 1 is in an unassembled state, as shown in Fig. 5, the second side wall portion 200 is contracted, and the second side wall portion upper section 201, the second side wall portion middle section 202, and the second side wall portion lower section 203 overlap in this order. The second insertion portions 222 of the second side wall portion middle section 202 and the second side wall portion lower section 203 overlap each other at their opening regions, and also overlap with the first insertion portion 122 of the first insertion portion 122. The belt member 300 extends from the side wall attached portion 204, penetrating the overlapping first and second insertion portions 122, 222, to the second attached portion 105 in the center of the bottom plate portion 110.

[0045] In addition, the bottom mounting portion 305 engages the second mounting portion 105, thereby maintaining the shape of the container 1 shown in the figure (unassembled state) and preventing the second side wall portion 200 from inadvertently stretching (to the assembled state of Figures 1 and 2).

[0046] When transitioning from the assembled state to the unassembled state, the bottom mounting portion 305 of the belt member 300 is guided by the rail portion 107 provided on the upper surface of the bottom plate portion 110 and moves from the first mounting portion 103 to the second mounting portion 105.

[0047] The container 1 is provided with a handle 500 on the second side wall 200 (second side wall upper stage 201). The handle 500 is disposed on a pair of short edges (side wall 200B, 200B') of the second side wall upper stage 201 having a rectangular peripheral edge. The handle 500 has a structure penetrating in the vertical direction, and an operator can place his / her hand or finger on it. When the container 1 is in an unassembled state as shown in FIG. 5, one handle 500 faces the zenith side and the other handle 500 faces the ground side, and the container 1 can be held in one hand by gripping one handle 500, making it easy to carry.

[0048] The grip portion 500 is integrally formed with the second side wall upper section 201. The grip portion 500 only needs to be able to hook a finger. Therefore, in the state of FIG. 1, it may be formed by penetrating in the vertical direction, or by a recess that does not penetrate. By providing the grip portion 500, when the handle portion 400 is in the first position, a gap 700 is formed between the grip portion 500, the handle portion 400, and the flange portion 250 (the upper end surface of the side wall portion). FIG. 8 clearly shows this configuration. By inserting the tip of the hand (fingertip) into this gap 700, the handle portion 400 in the first position can be easily raised with the fingertips and moved to the second position.

[0049] Furthermore, in order to facilitate the erection of the handle portion 400, it is preferable that the end of the handle portion 400 protrudes outward to the side more than the flange portion 250. This makes it easier for the operator to hook his / her fingers on the end of the handle portion 400, making it even easier to erect the handle portion 400.

[0050] As described above, the handle portion 400 in the first position shown in FIG. 1 and FIG. 5 is inclined so as to follow a pair of side walls 200B, 200B' extending upward from each of a pair of short sides of the peripheral portion of the rectangular bottom plate portion 110. Here, a flange portion 250 protruding outward is provided at the upper end of the side wall portion (second side wall portion upper stage 201), i.e., at the edge of the opening 1a. Furthermore, a wall portion 260 extending in at least one of the upward and downward directions is provided at the tip of the flange portion 250. In this embodiment, the tip of the flange portion 250 is provided with a wall portion 260 as a lower wall portion extending downward, but this is not limited thereto. For example, the wall portion 260 may extend in the vertical direction at the tip of the flange portion 250. A rotation restricting portion 600 is provided on the inner side of the wall portion 260.

[0051] The rotation restriction part 600 will be described in detail with reference to Figs. 6 and 7. Fig. 6 is a perspective view showing the container 1 in a position in which one of the handle parts 500 faces the zenith side. In Fig. 6, the bottom plate part 110 is spread out in a vertical plane (XZ plane). Fig. 7 is a view of the container 1 as seen from the direction of the arrow shown in Fig. 6, showing a cross section of the container 1 partially cut along the handle part 400 on the positive side of the Z axis from the imaginary center line M.

[0052] The rotation restricting portion 600 has a locking body 601 and a locked body 602 provided on each of both ends 401 of the handle portion 400. The locked body 602 is provided on the inner side of the wall portion 260.

[0053] When handle portion 400 is in the first position, locked body 602 is locked to locking body 601, thereby restricting handle portion 400 from rotating about rotating shaft portion 270 in a direction toward the second position. To achieve this, locked body 602 has a convex structure that protrudes in the negative direction of the Z axis in the state of Fig. 7, and locking body 601 has a concave structure into which locked body 602 fits. Note that flange portion 250 and locked body 602 are reinforced by rib 280 that protrudes downward (i.e., in the negative direction of the Y axis) from flange portion 250 as shown in Fig. 7.

[0054] The length of the protruding convex structure of the locked body 602 is relatively short, and the depth of the recess of the concave structure of the locking body 601 is relatively shallow. This is because it is necessary to realize a degree of locking that can restrict the handle unit 400 in the state shown in Fig. 7 from rotating in the direction toward the second position under its own weight, while also realizing a degree of locking that can easily release the locked state if a force is applied by the user to raise the handle unit 400 in the state shown in Fig. 1.

[0055] Such a rotation restricting portion 600 is formed on the inner side of the wall portion 260 as shown in the lower part of Fig. 7. This makes it possible to prevent the rotation restricting portion 600 from being damaged due to an external impact being directly applied to the rotation restricting portion 600.

[0056] By providing the rotation restriction portion 600 in this manner, the handle portion 400 will not rotate inadvertently even when the container 1 is in a tilted position as shown in Figures 6 and 7. This makes it possible to avoid the risk of the handle portion rotating inadvertently and coming into contact with another structure, resulting in damage.

[0057] 6, the rotation of the other handle portion 400 is restricted by rotation restricting portions 600 provided on both ends 401 of the handle portion 400. Therefore, even if the container 1 is shaken while being carried in a fallen position as shown in FIGS. 6 and 7, the other handle portion 400 can be prevented from contacting the flange portion 250, thereby preventing noise due to contact and damage to the handle portion 400 due to the impact.

[0058] If the second side wall portion 200 is configured to expand and contract in multiple stages, as in the container 1 of this embodiment, the shape of the container 1 can be made compact when not in use, making it easy to carry and contributing to saving storage space.

[0059] Here, the container of the first embodiment has a shape that opens wider as the second side wall 200 extends upward. That is, the first side wall 120 has a frame shape with the smallest diameter, and the second side wall lower stage 203 has a frame shape with a larger diameter than the first side wall 120. Furthermore, the second side wall middle stage 202 has a frame shape with a larger diameter than the second side wall lower stage 203, and the second side wall upper stage 201, which is located at the top, has a frame shape with a larger diameter than the second side wall middle stage 202.

[0060] FIG. 8 shows a cross-sectional view of such an embodiment in an unassembled state. FIG. 8 is a partial cross-sectional view taken along the line AA' in FIG. 5. FIG. 8 shows the handle portion 400 in a first position. As shown in FIG. 8, with the first side wall portion 120, the second side wall portion lower section 203, the second side wall portion middle section 202, and the second side wall portion upper section 201 overlapping laterally in this order, the container 1 is arranged such that the upper end of the handle portion 400 (H in FIG. 8) is in a first position. 2 The position indicated by H in FIG. 8) is the upper end of the first side wall portion 120. 1 ) or on the same plane as the upper end H 1 In other words, the height (H 2 ) is the height (H 1 ) is configured lower.

[0061] H 1 and H 2 8, when a load is placed on the container 1, the upper end (H 2 ) than the upper end (H 1) is subjected to the load of the luggage. This makes it possible to prevent damage to the handle portion 400. In other words, with the above-mentioned configuration, the load of the luggage is applied to the upper end of the first side wall portion, but is not applied to the second side wall portion. This makes it possible to prevent the load of the luggage from being applied to the connection portion between the first side wall portion 120 and the lower stage 203 of the second side wall portion, and to the connection portion between the second side wall portions. This makes it possible to prevent these from being damaged.

[0062] Each component of the container 1 may be made of the same material, for example, polypropylene (PP), but is not limited thereto. The belt member 300 must support the second side wall 200 by bracing it at one end 301 side and the other end 302 side so that the stretched second side wall 200 does not shrink when assembled. Therefore, it must have a degree of rigidity that can achieve this, and is realized with a size (belt width, belt thickness) that enables this. The handle portion 400, including the locking body 601, may also be made of, for example, PP.

[0063] [Modifications] In the above embodiment, the second side wall 200 has a shape that opens wider as it extends upward. That is, the first side wall 120 has a frame shape with the smallest diameter, and the second side wall lower stage 203 has a frame shape with a larger diameter than the first side wall 120. Furthermore, the second side wall middle stage 202 has a frame shape with a larger diameter than the second side wall lower stage 203, and the second side wall upper stage 201, which is located at the top, has a frame shape with a larger diameter than the second side wall middle stage 202. However, the present invention is not limited to this. The first side wall 120 may have a frame shape with the largest diameter, and frames with smaller diameters may be stacked on top of each other.

[0064] In the above embodiment, the second side wall portion 200 has a mechanism for telescopically expanding and contracting with respect to the bottom wall constituent portion 100, but the present invention is not limited to the telescopic mechanism. For example, the second side wall portion 200 may have a folding mechanism. Even in this folding mechanism, the belt member 300 described above prevents the second side wall portion 200 from being displaced, and the shape of the container (folded state, or unfolded and assembled state) is maintained.

[0065] As an embodiment of a container having a folding mechanism, although not shown in the drawings, a pair of side walls may have a mechanism for rotating and displacing the pair of side walls inward from the assembled state, and another pair of side walls may have a mechanism (e.g., a hinge structure) for folding the side walls inward at the middle part in the vertical direction of the side walls. By providing these mechanisms, the pair of side walls can be rotated and displaced inward, and the other pair of side walls can be folded inward with the hinge structure provided at the middle part as a fulcrum. This allows the container to be in a folded state. Note that even in a container having these mechanisms, the folded state can be maintained by providing a restricting mechanism for restricting the movement from the folded state to the unfolded state.

[0066] In the above embodiment, the first insertion portion 122 is a through hole whose outer periphery is surrounded by the first side wall portion, and the second insertion portion 222 is also a through hole whose outer periphery is surrounded by the second side wall portion lower stage 203 or the second side wall portion middle stage 202. However, the present invention is not limited to this. For example, the first insertion portion 122 may be realized in the form of a notch whose outer periphery is cut out at the upper end of the first side wall portion. Also, the second insertion portion 222 may be realized in the form of a notch whose outer periphery is cut out at the lower end of the second side wall portion lower stage 203 or the second side wall portion middle stage 202.

[0067] In the above embodiment, the two belt members 300 are attached to a pair of short edges of the second side wall upper stage 201 having a rectangular peripheral edge. However, the present invention is not limited to this. For example, the belt members 300 may be attached to a pair of long edges of the second side wall upper stage 201 having a rectangular peripheral edge. In another embodiment, the belt members 300 may be provided on a pair of long edges and a pair of short edges of the second side wall upper stage 201 having a rectangular peripheral edge. This embodiment includes four belt members. The two belt members 300 described in the above embodiment may be connected to each other at the other end portions 302. In other words, the belt members 300 may be realized as one belt member. In this case, a structure having elasticity or a structure such as a hinge may be provided between the other end portions 302 so that the length between the other end portions 302 can be changed.

[0068] In the above embodiment, the container 1 has an outer shape of a rectangular parallelepiped, but the present invention is not limited to this. The first side wall portion 120 and the second side wall portion 200 may have a cylindrical shape. In this case, the handle portion 400 is configured in an arc shape, not in a shape consisting of three consecutive sides of the four sides of the quadrangle described above.

[0069] In the above embodiment, the side wall expands and contracts to change the shape of the container 1, but the present invention is not limited to this. The storage space of the container 1 may be fixed, and both the bottom and side portions may have a flat plate-like structure similar to a shopping cart found in a typical store.

[0070] 〔summary〕 The container according to aspect 1 of the present invention is a container having an opening at the top, the handle portion being connected to a portion of the container near the opening, the handle portion being displaceable by rotation between a first position in which it lies flat along the edge of the opening and a second position in which it stands up from the edge and the container can be carried using the stood up portion, a grip portion extending laterally from the outer surface of the container, and a rotation restriction portion which restricts the rotation of the handle portion from the first position to the second position.

[0071] According to the above-mentioned configuration, the rotation restricting portion can restrict inadvertent rotation of the handle member, thereby preventing noise caused by the handle rotating inadvertently and colliding with the edge of the container, and preventing the handle from being damaged by contacting a structure or the like.

[0072] A container according to aspect 2 of the present invention may be configured in such a way that, in aspect 1, the container comprises a generally plate-shaped bottom plate portion and a side wall portion extending upward from a peripheral portion of the bottom plate portion, and when the container is tilted over so that the opening faces to the side, the handle portion is provided on the portion of the side wall surface facing upward, a flange portion is provided on the edge of the opening and protrudes outwardly to the side, a wall portion is provided at the tip of the flange portion extending in at least one of the upward and downward directions, and the rotation regulating portion is provided on the inward side of the wall portion when the container is tilted over so that the opening faces to the side.

[0073] According to the above configuration, the container can be easily carried in a state in which the container is laid down so that the opening faces to the side by gripping the handle portion.

[0074] Furthermore, according to the above configuration, the rotation restricting portion is provided on the inner side of the wall portion, so that the rotation restricting portion can be prevented from being damaged by the wall portion.

[0076] According to the above-mentioned configuration, since the rotation restricting portion is formed on the flange portion, it is difficult for the rotation restricting portion to come into contact with the object to be locked when putting an article into the container, so that it is possible to prevent damage to the rotation restricting portion and also to prevent damage to the article to be put in and stored.

[0077] A container according to aspect 4 of the present invention may be configured in such a way that, in aspect 2, the container comprises a bottom plate portion which is a rectangular bottom plate, and a side wall portion extending upward from a peripheral portion of the bottom plate portion, the side wall portion including two pairs of side wall portions opposing each other across the storage portion of the container, the handle portion is connected to a pair of the side wall portions, and when the container is in the first position, the handle portion is along the upper ends of the other pair of side wall portions, the grip portion is provided on the other pair of side wall portions, and a gap is formed between the handle portion in the first position, the upper end faces of the other pair of side wall portions, and the grip portion.

[0078] According to the above configuration, the handle portion can be easily raised using the gap.

[0079] The container according to aspect 5 of the present invention, in accordance with aspects 1 to 5, comprises a bottom plate portion which is a rectangular bottom plate, and a side wall portion extending upward from a peripheral portion of the bottom plate portion, wherein the side wall portion is configured to be folded or to contract telescopically relative to the bottom plate portion to reduce the size of the storage portion of the container, while being unfolded or to expand telescopically relative to the bottom plate portion to return to the original size, and may further comprise a regulating mechanism for regulating the movement of the side wall portion associated with the change in size.

[0080] According to the above-mentioned configuration, since the side wall portion is foldable or expandable, when no items are stored in the container of the present invention, the side wall portion can be folded or contracted to give the container a compact shape, making it convenient to store and carry as it does not take up much space.

[0081] Furthermore, with the above-described configuration, the restricting mechanism prevents the folded side wall portion from unfolding in an inconvenient manner, and prevents the telescopically contracted side wall portion from expanding in an inconvenient manner.

[0082] A container according to aspect 6 of the present invention may be configured in such a way that, in aspect 6, the regulating mechanism is a belt-shaped member, and the regulating mechanism has a side wall mounting portion provided at one end and attached to the side wall portion, and a bottom mounting portion provided at the other end and attached to the bottom plate portion, and the bottom plate portion is provided with a first mounting portion to which the bottom mounting portion is attached when the side wall portion is unfolded or telescopically extended, and a second mounting portion which is located at a position different from the first mounting portion and to which the bottom mounting portion is attached when the side wall portion is folded or telescopically contracted, and the bottom mounting portion is configured to be displaceable between the first mounting portion and the second mounting portion.

[0083] According to the above-described configuration, the restricting mechanism, which is a belt-shaped member, can prevent the side wall portion from being displaced in the up-down direction.

[0084] A container according to aspect 7 of the present invention is any of the containers according to aspects 1 to 7, which comprises a bottom plate portion that is a rectangular bottom plate and a side wall portion extending upward from a peripheral portion of the bottom plate portion, and the side wall portion is configured to be folded or to contract telescopically relative to the bottom plate portion to reduce the size of the storage portion of the container, while being unfolded or to extend telescopically relative to the bottom plate portion to return to the original size, and when the side wall portion is folded or contracted telescopically, the upper end of the handle portion, which is in the first position and leans along the upper end of the side wall portion, may be configured to be on the same plane as the upper end of the side wall portion or to be located lower than the upper end of the side wall portion.

[0085] According to the above configuration, when luggage is placed on the container with the side wall portion contracted, the weight of the luggage is placed on the upper end of the side wall portion rather than on the upper end of the handle portion which is leaning along the upper end of the side wall portion, thereby preventing damage to the handle portion.
