Mode for Carrying Out the Invention

[0011] Hereinafter, the container of one embodiment of the present invention will be described in detail. The container of this embodiment has an appearance similar to a shopping basket used in a store or the like. As an example, in the accommodation space defined by the inner surface of the container, a store shopping basket can be stacked, and it can also be realized as a mode in which articles can be put into the accommodation space and carried.

[0012] In particular, the container of this embodiment can change its shape into a compact mode when there is no article or shopping basket in the accommodation space, that is, in a so-called non-accommodated state. Furthermore, it is configured such that the shape does not change inconveniently (return to the original state) in this compact mode. Hereinafter, an example of an embodiment for realizing this configuration will be described. In the following description of the components, the terms "upper" and "lower" may be used. In this specification, when the container of this embodiment is placed with the bottom plate portion of the bottom wall component horizontally with respect to the horizontal plane, the direction along the vertical direction toward the zenith is defined as the upper (direction), and the opposite direction is defined as the lower (direction), and this definition is used.

[0013] FIG. 1 is an external perspective view of the container 1 of the present embodiment when the container is in a non-assembled state. Here, the "non-assembled state" is a state in which the second side wall portion 200 described later is contracted, and it is the form of the container 1 when carrying or storing the container 1 itself. On the other hand, FIG. 2 is an external perspective view of the container 1 when the container 1 is in an assembled state. Here, the "assembled state" is a state in which a storage space for putting articles or a shopping basket is assembled, and it is a state in which the second side wall portion 200 described later is assembled to the bottom wall component 100.

[0014] That is, the container 1 of the present embodiment 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 edge of the bottom plate portion 110, and a second side wall portion 200 forming a cylindrical body and telescopically extending and contracting with respect to the bottom wall component 100. Further, the container 1 includes a belt member 300 connecting the bottom wall component 100 and the second side wall portion 200, which restricts the second side wall portion 200 from contracting when the second side wall portion 200 is in a state of extending with respect to the bottom wall component 100, and restricts the second side wall portion 200 from extending when the second side wall portion 200 is in a state of contracting with respect to the bottom wall component 100.

[0015] Here, FIG. 3 is an exploded perspective view of the container 1 disassembled by each component and viewed from the upper side of the container 1, and FIG. 4 is an exploded perspective view of the disassembled state viewed from the lower side of the container 1.

[0016] The bottom wall component 100 is a box-shaped structure including a substantially plate-shaped bottom plate portion 110 and a first side wall portion 120 extending upward from the peripheral edge of the bottom plate portion 110. Since the container of the present embodiment has the same specifications as a so-called shopping basket, a large number of through holes are provided in the bottom wall component 100. Further, a first engaged portion 103 and a second engaged portion 105 are provided in the bottom wall component 100.

[0017] The first engaged part 103 is the part to be engaged by the engaging part 305 of the belt member 300. The first engaged part 103 is provided at the boundary between the bottom plate part 110 and the first side wall part 120. In the example shown in FIGS. 1 to 4, the first engaged parts 103 are respectively provided at the middle positions of a pair of short edges of the bottom plate part 110 having a rectangular peripheral edge. Each first engaged part 103 is a hole penetrating from the inner surface to the outer surface of the bottom wall component 100, and the engaging part 305 of the belt member 300 can be inserted and fitted therein. When the container 1 is in the assembled state, the engaging part 305 of a separate belt member 300 (FIG. 5) is engaged with one first engaged part 103 and the other first engaged part 103.

[0018] The second engaged parts 105 are arranged in two along a pair of long edges of the bottom plate part 110 having a rectangular peripheral edge at the central part of the bottom plate part 110. When the container is in the unassembled state, the engaging part 305 of a separate belt member 300 (FIG. 5) is engaged with one second engaged part 105 and the other second engaged part 105.

[0019] The first engaged part 103 and the second engaged part 105 are engaged with the engaging part 305 of the belt member 300 when the container 1 takes different forms. Specifically, the engaging part 305 is engaged with the first engaged part 103 when the container 1 is in the assembled state, and is engaged with the second engaged part 105 when the container 1 is in the unassembled state.

[0020] On the upper surface of the bottom plate part 110, a rail part 107 (FIGS. 1 and 3) is further provided.

[0021] The rail part 107 extends between one second engaged part 105 and the first engaged part 103 provided on the short edge of the rectangular bottom plate part 110 closest to this second engaged part 105. The rail part 107 further extends between the other second engaged part 105 and the first engaged part 103 provided on the short edge of the rectangular bottom plate part 110 closest to this second engaged part 105.

[0022] The first side wall portion 120 corresponds to a portion rising from the peripheral edge of the bottom plate portion 110 having a rectangular peripheral side. The first side wall portion 120 rises substantially perpendicular to the upper surface of the bottom plate portion 110. In addition to a large number of through holes, a slit portion 120b extending vertically along the wall surface is formed in the first side wall portion 120. A convex portion 203a provided at 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 extend and contract with respect to the bottom wall component 100. As shown in FIGS. 3 and 4, three slit portions 120b are respectively provided on a pair of long edges of the first side wall portion 120 having a rectangular peripheral side. Note that the number is not limited to this.

[0023] Here, as shown in FIGS. 3 and 4, in the container 1 of the present embodiment, the second side wall portion 200 has a configuration in which a plurality of stages are connected in series. Specifically, it includes an upper-stage second side wall portion 201 located at the uppermost stage in the assembled state, a middle-stage second side wall portion 202 located in the middle stage, and a lower-stage second side wall portion 203 located at the lower stage. The above-mentioned convex portion 203a is provided on the inner surface of the lower-stage second side wall portion 203 and is slidably fitted into the slit portion 120b of the first side wall portion 120.

[0024] Also, a plurality of slit portions lower-stage 203b, which are slits extending vertically along the wall surface in the same manner as the slit portion 120b, are formed at a plurality of locations in the lower-stage second side wall portion 203. Convex portions middle-stage 202a provided on the inner surface of the middle-stage second side wall portion 202, which are the same as the previous convex portion 203a, are slidably fitted into these slit portions lower-stage 203b.

[0025] Furthermore, a plurality of slit portions middle-stage 202b, which are slits extending vertically along the wall surface in the same manner as the slit portion 120b, are formed at a plurality of locations in the middle-stage second side wall portion 202. Convex portions upper-stage 201a provided on the inner surface of the upper-stage second side wall portion 201, which are the same as the previous convex portion 203a, are slidably fitted into these slit portions middle-stage 202b.

[0026] By lowering these convex portions 203a, 202a, and 201a with respect to the slit portions 120b, 203b, and 202b, the second side wall portion 200 in the assembled state shown in FIG. 2 becomes the state (non-assembled state) shown in FIG. 1, which is shorter and contracted with respect to the bottom wall forming portion 100. Conversely, from the non-assembled state shown in FIG. 1, by raising the convex portions 203a, 202a, and 201a with respect to the slit portions 120b, 203b, and 202b, the second side wall portion 200 stands up and extends with respect to the bottom wall forming portion 100 as shown in FIG. 2, resulting in an assembled state.

[0027] The second side wall portion 200 that telescopically extends and contracts in this way has its extension and contraction movement restricted by the belt member 300. The structure of this belt member 300 will be described with reference to FIGS. 5 and 6.

[0028] FIG. 5 is a perspective view of the belt member 300 as viewed from the upper surface side, which is the same view as that of the belt member 300 shown in FIG. 1 from the upper surface side. FIG. 6 is a perspective view of the belt member 300 as viewed from the lower surface side, which is a view of the state when the belt member 300 shown in FIG. 5 is turned over.

[0029] The belt member 300 is belt-shaped and has a predetermined length in the longitudinal direction. A mounting portion 303 is provided at one end portion 301, and a locking portion 305 is provided at the other end portion 302.

[0030] The mounting portion 303 has a structure that is mounted on the upper end of the second side wall portion 200, specifically, on the upper stage 201 of the second side wall portion. Here, FIG. 7 is a partial cross-sectional perspective view when the container 1 is in the assembled state. FIG. 8 is a partially enlarged view showing a part of the inner surface of the upper part (upper stage 201 of the second side wall portion) of the container 1 when the container 1 is in the assembled state. As shown in FIGS. 7 and 8, a mounted portion 204 on which the mounting portion 303 is mounted is provided on the upper stage 201 of the second side wall portion. When the mounting portion 303 is inserted into and mounted on the mounted portion 204, it cannot be easily removed, and one end portion 301 of the belt member 300 can be fixed to the upper stage 201 of the second side wall portion.

[0031] The locking portion 305 is provided on the lower surface of the other end portion 302. Specifically, the locking portion 305 is a locking shaft portion protruding from the lower surface of the other end portion 302. The locking portion 305 has a constricted portion in the protruding shape such that the cross-sectional shape becomes a T shape in the middle. The locking portion 305 can be inserted into the first locked portion 103 and the second locked portion 105 of the bottom wall component 100 described above. In the assembled state shown in FIGS. 2 and 7, the locking portion 305 is inserted into the first locked portion 103. Here, with reference to FIG. 9, the locking between the locking portion 305 and the first locked portion 103 will be described.

[0032] FIG. 9 is a partially enlarged view of a part of the outer surface of the first side wall portion 120 at the lower part of the container 1 when the container 1 is in the assembled state.

[0033] As shown in FIG. 9, the first locked portion 103 is composed of two vertically arranged through regions. An insertion region 103a with a large opening diameter is provided on the upper side, and a fitting region 103b with an opening diameter smaller than that of the insertion region 103a is provided on the lower side. The opening diameter of the insertion region 103a is wider than the outer diameter of the locking portion 305 (locking shaft portion). On the other hand, the fitting region 103b opens with a diameter substantially the same as the diameter of the constricted portion in the protruding shape of the locking portion 305 (locking shaft portion). The insertion region 103a and the fitting region 103b are continuous. When locking the locking portion 305 to the first locked portion 103, the locking portion 305 is inserted into the insertion region 103a from the inner surface side of the bottom wall component 100, and in the inserted state, the locking portion 305 is moved downward to be fitted into the fitting region 103b. FIG. 9 shows a state where the locking portion 305 is locked to the first locked portion 103 (fitting region 103b).

[0034] In the state where the locking portion 305 is locked to the first locked portion 103, as shown in FIG. 7, since the belt member 300 extends upward and has a predetermined rigidity, it is possible to restrict the telescopic contraction of the second side wall portion 200 extended upward due to its own weight.

[0035] The locking part 305 that locks the fitting area 103b of the first locked part 103 can move to the insertion area 103a, and by moving to the insertion area 103a, the locking part 305 can be moved to the inner surface side of the bottom wall component 100. By moving the locking part 305 to the inner surface side of the bottom wall component 100, the locking part 305 can release the locked state with the first locked part 103. Regarding the operation of moving the locking part 305 to the insertion area 103a, the finger hook part 111 shown in FIG. 9 can be used.

[0036] The finger hook part 111 is a protruding part provided on the outer surface of the bottom wall component 100 (the first side wall part 120), and is formed to protrude outward from a position above the first locked part 103. The operator can operate the finger hook part 111 and the locking part 305 (locking shaft part) with fingers, whereby the locked state of the locking part 305 can be easily released. Therefore, the expansion and contraction operation of the second side wall part 200 can be efficiently performed from the outside of the container 1.

[0037] On the outer surface of the bottom wall component 100 (the first side wall part 120), further, a rib 112 shown in FIG. 9 is provided. The rib 112 protrudes outward like the finger hook part 111 and is formed to extend in the vertical direction. Two ribs 112 are provided with the finger hook part 111 interposed therebetween. The two ribs 112 and the finger hook part 111 are continuously connected. The first locked part 103 is located between the two ribs 112. The outer end surface of the rib 112 has a height of protrusion outward from the outer surface of the bottom wall component 100 (the first side wall part 120) higher than the protruding end of the locking part 305 (locking shaft part) in a state where the locking part 305 is locked to the first locked part 103. Thereby, the locking part 305 (locking shaft part) locked to the first locked part 103 does not protrude outward beyond the outer end surface of the rib 112. With this configuration, it is possible to prevent the locking part 305 (locking shaft part) from being caught and the locked state from being released when the container 1 is placed.

[0038] Note that, as shown in FIG. 5, an operation portion 306 is formed at the other end portion 302 of the belt member 300. By the operator operating the operation portion 306, the locked state of the locking portion 305 can be released. Specifically, the operator displaces the operation portion 306 upward to release the locked state, grips the lifted curved portion 307, and disengages the locking portion 305 (locking shaft portion) from the first locked portion 103. The disengaged locking portion 305 (locking shaft portion) is guided to the second locked portion 105 by the rail portion 107. That is, in the present embodiment, the release of the locking of the locking portion 305 in the locked state can be operated not only from the outside of the container 1 using the finger hook portion 111 but also from the inside of the container 1 using the operation portion 306. The operation using the operation portion 306 is effective even when there is no space to operate the finger hook portion 111.

[0039] Here, the installation mode of the belt member 300 in the assembled state will be described with reference to FIG. 10 together with FIG. 7. FIG. 10 is a partial cross-sectional view of the container when the container is in the assembled state, showing a state cut along the longitudinal direction of the belt member 300.

[0040] As shown in FIGS. 7 and 10, a first insertion portion 122 for inserting the belt member 300 is provided in the first side wall portion 120. Further, second insertion portions 222 for inserting the belt member 300 are provided in the lower stage 203 and the middle stage 202 of the second side wall portion of the second side wall portion 200, respectively. The first insertion portion 122 and the second insertion portions 222 are formed to have substantially the same width as the width of the belt member 300. Since the displacement of the belt member 300 in the width direction is restricted by the edge portions of the first insertion portion 122 and the second insertion portions 222, the rattling of the belt member 300 can be suppressed. Further, when moving the belt member 300 along with the expansion and contraction of the second side wall portion 200, the belt member 300 can be stably operated.

[0041] Incidentally, a chamfered shape 109 is provided at the boundary between the bottom plate portion 110 and the first side wall portion 120 of the bottom wall component 100. On the other hand, the other end 302 of the belt member 300 includes a curved portion 307 (FIGS. 5 and 10) that curves away from the bottom plate portion 110 in a state where the second side wall portion 200 is contracted and locked to the second locked portion 105. This curved portion 307 is formed along the chamfered shape 109. Thus, when the second side wall portion 200 is in an extended state, the curved portion 307 is provided so as to fit the chamfered shape 109. The locking portion 305 protrudes from the lower surface of the curved portion 307. By providing the curved portion 307, in a state where the second side wall portion 200 is contracted and the other end 302 is locked to the second locked portion 105, the curved portion 307 is in a state of being separated from the bottom plate portion 110. As a result, the operator can easily grip the other end 302, improving the operability of the belt member 300. Further, when the second side wall portion 200 is extended and the locking portion 305 is locked to the first locked portion 103, since the curved portion 307 fits along the chamfered shape 109, it is possible to prevent an article from being pinched between the belt member 300 (particularly, the other end 302 of the belt member 300) and the bottom wall component 100.

[0042] Furthermore, at the end of the chamfered shape 109, a protective portion 109a (FIG. 7) for protecting the side surface of the belt member 300 is provided. Specifically, the protective portion 109a (FIG. 7) provided at the end of the chamfered shape 109 guards the side surface of the curved portion 307 when the curved portion 307 is fitted to the chamfered shape 109 and protects the curved portion 307 from external impacts. The protective portion 109a is a wall rising from the end of the chamfered shape 109 and has a surface facing the side surface of the curved portion 307. The protective portions 109a are provided in pairs so as to sandwich the curved portion 307 from both end surfaces in the width direction of the belt member 300. By providing such protective portions 109a, it is possible to prevent an article accommodated in the container 1 from colliding from the side of the belt member 300 and damaging the locking portion 305. Further, it is possible to prevent an article accommodated in the container 1 from colliding from the side of the belt member 300 and the locking portion 305 from unexpectedly detaching from the first locked portion 103. In this example, the protective portion 109a protects only the curved portion 307, but the protective portion 109a may be continuously formed up to the upper end of the first side wall portion 120 and, in addition to the curved portion 307, protect the belt member 300 in a range extending up to the upper end of the first side wall portion 120.

[0043] Here, as shown in FIG. 11, the chamfered shape 109 is provided with a recess that is one step lower than the surface of the bottom plate portion 110, and the curved portion 307 is accommodated in this recess. Thereby, it is possible to prevent the curved portion 307 from protruding from the bottom plate portion 110 and suppress damage to the article accommodated in the container 1.

[0044] Note that in the present embodiment, the curved portion 307 is protected by the recess and the protective portion 109a of the chamfered shape 109, but it may be protected only by the recess of the chamfered shape 109, or may be protected only by the protective portion 109a.

[0045] When the container 1 is in the assembled state as shown in Fig. 2, the operator can rotate the handle member 400 to lift it up, and then hold the lifted handle member 400 by hand or pass the arm through it to lift the container 1. Thus, the container 1 can be lifted in the same manner as a shopping basket commonly seen in stores and the like.

[0046] Next, the position of the belt member 300 in the unassembled state will be described with reference to Figs. 11 and 12 together with Fig. 1. Fig. 11 is a partial cross-sectional view of the container when the container 1 is in the unassembled state, and Fig. 12 is a partial cross-sectional view of the container taken along the cutting line A - A' shown in Fig. 11. In the unassembled state, the second side wall portion 200 is contracted, and the upper stage 201 of the second side wall portion, the middle stage 202 of the second side wall portion, and the lower stage 203 of the second side wall portion overlap in this order. And the second insertion portions 222 of the middle stage 202 and the lower stage 203 of the second side wall portion overlap in the opening region, and also overlap with the first insertion portion 122 of the first side wall portion 120. The belt member 300 extends from the attached portion 204 through the overlapping first and second insertion portions 122 and 222 to the second engaged portion 105 at the center of the bottom plate portion 110.

[0047] Here, when changing the shape of the container 1 from the assembled state to the unassembled state, as described above, place a finger on the finger hook portion 111 to release the engagement between the first engaged portion 103 and the engaging portion 305. The engaging portion 305 released in this way slides along the rail portion 107 guided by the rail portion 107 to the second engaged portion 105 at the center of the bottom plate portion 110 as the second side wall portion 200 to which the belt member 300 is attached is displaced downward by its own weight. Thereby, the operator can stably operate the belt member 300.

[0048] As shown in Figs. 1, 11, and 12, the engaging portion 305 holds the shape (unassembled state) of the illustrated container 1 by engaging with the second engaged portion 105, and restricts the second side wall portion 200 from extending inconveniently (to the assembled state in Fig. 2).

[0049] When changing the shape of the container 1 from the unassembled state to the assembled state, when changing the shape of the container 1 from the unassembled state to the assembled state, the upper part 201 of the second side wall portion to which the belt member 300 is attached is pushed upward by the belt member 300 having rigidity by the sliding operation of the belt member 300, and then, the middle part 202 of the second side wall portion connected to the upper part 201 of the second side wall portion is displaced upward to be assembled. Thus, the shape can be changed to the assembled state only by operating the belt member 300, and the assembling workability is excellent.

[0050] The bottom wall component 100 and the second side wall portion 200 can be made of the same material. For example, it can be made of polypropylene (PP), but is not limited thereto. The belt member 300 can also be made of, for example, PP. The belt member 300 needs to support the second side wall portion 200 so that the extended second side wall portion 200 does not shrink at one end portion 301 side and the other end portion 302 side when in the assembled state. Therefore, it is necessary to have rigidity to the extent that it can be realized, and it is realized with a size (belt width, belt thickness) that enables it.

[0051] In addition, as shown in FIG. 1, for example, a handle portion 500 is provided on the second side wall portion 200 (the upper part 201 of the second side wall portion). The handle portion 500 is disposed on a pair of short edges of the upper part 201 of the second side wall portion having a rectangular peripheral edge, respectively. The handle portion 500 has a structure that penetrates in the vertical direction, and a hand or a finger can be hooked. As shown in FIG. 1, when the container 1 is in the unassembled state, one handle portion 500 is directed toward the zenith side, the other handle portion 500 is directed toward the ground side, and one handle portion 500 is grasped, and the container 1 can be lifted with one hand, which is easy to carry. The carrying when the container 1 is in the unassembled state is not limited to this mode. It is also possible to carry the container 1 with both handle portions 500 grasped with the opening side of the container 1 facing the zenith as shown in FIG. 1. The handle portion 500 is integrally formed with the upper part 201 of the second side wall portion. Note that the handle portion 500 only needs to be able to hook a finger, and does not need to penetrate in the vertical direction in the state of FIG. 1, and may be constituted by a recess opened downward.

[0052] In the unassembled state shown in FIGS. 1, 11, and 12, the handle member 400 is arranged along the second side wall portion 200 (the upper part 201 of the second side wall portion).

[0053] As described above, according to the configuration of the container 1 of the present embodiment, since the second side wall portion 200 that telescopically expands and contracts is provided, when the container 1 does not contain an article, if the second side wall portion 200 is in a contracted state, the container 1 can be made into a compact shape, and it is convenient when storing and carrying without being bulky. Further, according to the configuration of the container 1 of the present embodiment, the belt member 300 can restrict the second side wall portion 200 from extending when the second side wall portion 200 is in a contracted state with respect to the bottom wall component 100. Therefore, the second side wall portion 200 does not inconveniently extend.

[0054] 〔Modification Example〕 In the above-described embodiment, as the second side wall portion 200 extends upward, it has a largely open shape. That is, the first side wall portion 120 forms the frame aspect with the smallest diameter, and the lower part 203 of the second side wall portion forms the frame aspect with a diameter larger than that of the first side wall portion 120. Further, the middle part 202 of the second side wall portion forms the frame aspect with a diameter larger than that of the lower part 203 of the second side wall portion, and the upper part 201 of the second side wall portion located at the uppermost stage forms the frame aspect with a diameter larger than that of the middle part 202 of the second side wall portion. However, the present invention is not limited to this. The first side wall portion 120 may form the frame aspect with the largest diameter, and the frames with smaller diameters may overlap as it goes upward. Also, in the above-described embodiment, there are three second side wall portions (the upper part 201 of the second side wall portion, the middle part 202 of the second side wall portion, and the lower part 203 of the second side wall portion), but there may be one.

[0055] In the above-described 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 lower stage 203 of the second side wall portion or the middle stage 202 of the second side wall portion. However, the present invention is not limited to this. For example, the first insertion portion 122 may be realized in a notch mode in which its outer periphery is missing at the upper end of the first side wall portion. Further, the second insertion portion 222 may be realized in a notch mode in which its outer periphery is missing at the lower end of the lower stage 203 of the second side wall portion or the middle stage 202 of the second side wall portion.

[0056] In the above-described embodiment, the two belt members 300 are attached to a pair of short edges of the upper stage 201 of the second side wall portion having a rectangular peripheral edge. However, the present invention is not limited to this. For example, it may be a mode in which they are attached to a pair of long edges of the upper stage 201 of the second side wall portion having a rectangular peripheral edge. As another mode, they may be provided on a pair of long edges and a pair of short edges of the upper stage 201 of the second side wall portion having a rectangular peripheral edge, respectively. This mode, that is, includes four belt members. Further, the two belt members 300 described in the above-described embodiment may be connected on the side of the other ends 302. In short, it may be realized as one belt member. In this case, a structure having elasticity or a structure such as a hinge may be disposed between the other ends 302 so that the length between the other ends 302 can be changed.

[0057] In the above-described embodiment, the container 1 has an approximately rectangular parallelepiped outer shape, 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. Further, as a modification of the above-described embodiment, a through-hole may be formed in which the rail portion penetrates the bottom plate portion and is continuous so as to connect the first engaged portion and the second engaged portion.

[0058] In the above-described embodiment, one end portion 301 of the belt member 300 is fixed to the inner surface of the upper stage 201 of the second side wall portion, and the locking position of the other end portion 302 is changed. However, the present invention is not limited to this. As a detachable locking portion for both the one end portion 301 and the other end portion 302, a locked portion is provided at an appropriate position of the bottom wall component portion 100 and the second side wall portion 200. When changing from the assembled state to the non-assembled state, the locking positions of both the one end portion 301 and the other end portion 302 may be changed to other locations.

[0059] 〔Summary〕 The container according to Aspect 1 of the present disclosure includes a bottom wall component portion including a substantially plate-shaped bottom plate portion and a first side wall portion extending upward from the peripheral edge portion of the bottom plate portion, a second side wall portion forming a cylindrical body and telescopically extending and contracting with respect to the bottom wall component portion, and a belt member that regulates the extending and contracting operation of the second side wall portion.

[0060] According to the above configuration, since the second side wall portion that telescopically extends and contracts is provided, when the container according to Aspect 1 of the present disclosure does not contain an article, if the second side wall portion is in a contracted state, the container can be made into a compact shape, and it is convenient without being bulky when storing and carrying.

[0061] Further, according to the above configuration, since the belt member restricts the second side wall portion from extending when the second side wall portion is in a contracted state with respect to the bottom wall component portion, the second side wall portion does not inconveniently extend.

[0062] The container according to Aspect 2 of the present disclosure may be configured such that, in the above Aspect 1, the belt member is provided with an attachment portion attached to the second side wall portion or a detachable locking portion with respect to the second side wall portion at one end portion.

[0063] According to the above configuration, one end portion of the belt member can be attached to the second side wall portion via the attachment portion. Further, one end portion of the belt member can be detachably attached to the second side wall portion via the locking portion.

[0064] In the container according to Embodiment 3 of the present disclosure, in the above Embodiment 1 or 2, at least one of the first side wall portion and the second side wall portion may be configured to be provided with an insertion portion through which the belt member is inserted.

[0065] According to the above configuration, since the displacement of the belt member in the width direction is restricted by the edge portion of the insertion portion, the rattling of the belt member can be suppressed. Further, according to the above configuration, when the belt member is moved along with the expansion and contraction of the second side wall portion, the belt member can be stably operated.

[0066] The shopping basket according to Embodiment 4 of the present disclosure includes a bottom wall component including a substantially plate-shaped bottom plate portion and a first side wall portion extending upward from the peripheral edge of the bottom plate portion, a second side wall portion forming a cylindrical body and telescopically expanding and contracting with respect to the bottom wall component, and a belt member that restricts the expansion and contraction operation of the second side wall portion.

[0067] According to the above configuration, since the second side wall portion that telescopically expands and contracts is provided, when the shopping basket according to Embodiment 4 of the present disclosure does not contain articles, the second side wall portion can be shrunk, and the shopping basket can be made into a compact shape, which is convenient for storage and carrying without being bulky. Further, according to the above configuration, since the belt member restricts the second side wall portion from expanding when the second side wall portion is in a contracted state with respect to the bottom wall component, the second side wall portion does not inconveniently expand.

[0068] 〔Supplementary Notes〕 The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope shown in the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention.
