In FIGS. 5 to 8, components identical to those of shopping basket 511 illustrated in FIGS. 4A and 4B are dented by the same reference numerals. Shopping basket 551 includes plate body 201 instead of plate body 22a of shopping basket 511 illustrated in FIGS. 4A and 4B, and does not include layout maintainer 4a. In other words, an upper surface of plate body 201 directly contact products. Plate body 201 is configured to close lower opening 12a, and slide in pull-out direction D501 with respect to main basket body 1 so as to open lower opening 12a.

Two side walls 14a of main basket body 1a include side wall 114a and side wall 114b positioned opposite to side wall 114a across internal space 501a in between. Two side walls 17a include side wall 117a extending from one of both ends of side wall 114a to one of both ends of side wall 114b, and side wall 117b extending from the other of both ends of side wall 114a to the other of both ends of side wall 114b. Side wall 117b is positioned opposite to side wall 117a across internal space 501a in between. Insertion slit 18 into which plate body 201 is inserted is provided in side wall 114a. Similarly to shopping basket 511 illustrated in FIGS. 4A and 4B, grooves 3g are provided in side walls 117a and 117b. Plate body 22a moves while sliding along grooves 3g in pull-out direction D501. Side wall 114b has groove 114g therein into which outer edge 2201 of plate body 201 fits when plate body 201 closes lower opening 12a. As illustrated in FIG. 7, similarly to grooves 3g provided in side walls 117a and 117b, groove 114g is constituted by guide rail 444 having upper piece 444a and lower piece 444b provided on an inner surface of side wall 114b facing internal space 501a. Groove 114g is formed between upper piece 444a and lower piece 444b. Groove 114g is connected with two grooves 3g of shopping basket 551, but may be separate from two grooves 3g.

FIG. 9 is a top view of plate body 201. As illustrated in FIGS. 5 and 9, plate body 201 has outer edges 1201, 2201, 3201, and 4201. Outer edge 2201 faces side wall 114b. Outer edge 1201 is positioned opposite to outer edge 1201. Outer edge 3201 faces side wall 117a and is connected with outer edges 1201 and 2201. Outer edge 4201 faces side wall 117b and is connected with outer edges 1201 and 2201. Outer edge 1201 faces the outside of main basket body 1.

As illustrated in FIG. 9, plate body 201 has end region 201p in pull-out direction D501, end region 201q opposite to end region 201p, and center region 201r positioned between end regions 201p and 201q and connected with end regions 201p and 201q. End region 201p includes outer edge 1201. End region 201q includes outer edge 2201.

As illustrated in FIG. 8, plate body 201 includes base plate 201s having a plate shape and rib 201t protruding from a lower surface of base plate 201s.

When products placed in shopping basket 551 are heavy, plate body 201 warps, and has outer edges 3201 and 4201 of plate body 201 pressed against grooves 3g. In this state, plate body 201 may be unable to slide smoothly along grooves 3g. If plate body 201 has a large thickness to enhance a rigidity of plate body 201 and suppress warpage, shopping basket 551 becomes heavy.

In shopping basket 551, a thickness of the base plate in the up-down direction gradually increases toward outer edge 2201 at least in end region 201q. Alternatively, the thickness of base plate 201s in the up-down direction may gradually increase toward outer edge 2201 at least in center region 201r and end region 201q. Alternatively, the thickness of base plate 201s in the up-down direction may gradually increase toward outer edge 2201, over whole plate body 201. Accordingly, an average of the thickness of end region 201q of plate body 201 in the up-down direction is larger than an average of the thickness of center region 201r in the up-down direction. This configuration allows the rigidity of end region 201q of plate body 201 to be larger than the rigidity of center region 201r. When plate body 201 is slid and partially open lower opening 12a, products are mainly placed on end region 201q instead of center region 201r. Hence, the rigidity is enlarged mainly in end region 201q of plate body 201, and not in end region 201p or center region 201r of plate body 201. This configuration suppresses the aforementioned warpage effectively, and allows plate body 201 to slide smoothly along grooves 3g without causing an excessive increase in a weight of plate body 201, that is, a weight of shopping basket 551.

Plate body 201 further includes plural ribs 201w protruding from an upper surface of base plate 201s. Ribs 201w are arranged in front-rear direction DAB, and extend slenderly in pull-out direction D501, that is, in left-right direction DCD. When products are stored in internal space 501a, the products contacts an upper surface of plate body 201. At this moment, if the products are put in an airtight bag or are wet, the products may adhere onto the upper surface of plate body 201. In this case, when plate body 201 moves in pull-out direction D501 through insertion slit 18, the product adhered onto the upper surface of plate body 201 hardly moves even if the product is pushed by side wall 114a, and hinders movement of plate body 201. In shopping basket 551, products contact upper ends of plural ribs 201w, and are partially separated from base plate 201s. This configuration reduces an area where the products contact the upper surface of plate body 201, so that the products are less likely to adhere onto the upper surface of plate body 201. This configuration allows products to move easily when plate body 201 moves in pull-out direction D501 through insertion slit 18 and the products are pushed by side wall 114a. Hence, plate body 201 can be moved smoothly.

In the case where a product is a thin product, such as a postal card, when plate body 201 is moved in pull-out direction D501 through insertion slit 18, the product may slide out of internal space 501a through a gap between an upper inner edge of insertion slit 18 and the upper surface of plate body 201, thus producing a problem that the product is prevented from being moved to the container through lower opening 12a. Shopping basket 551 prevents this problem with the following configuration.

FIG. 10 is an enlarged view of part AA of shopping basket 551 illustrated in FIG. 6, and shows insertion slit 18 provided in side wall 114a of main basket body 1a while plate body 201 is inserted into insertion slit 18. Insertion slit 18 of main basket body 1a has upper inner edge 18a facing the upper surface of base plate 201s of plate body 201, and lower inner edge 18b facing a lower surface of plate body 201. Main basket body 1a includes plural protrusions 18t protruding in downward direction DF from upper inner edge 18a of insertion slit 18. Plural protrusions 18t are interdigitated with plural ribs 201w when plate body 201 moves in pull-out direction D501 through insertion slit 18 while opening lower opening 12a. In according to Embodiment 1, plural ribs 201w and multiple protrusions 18t are arranged alternately. Each of some of protrusions 18t may be arranged between adjacent two ribs 201w among plural ribs 201w. Alternatively, each of some of ribs 201w may be arranged between respective adjacent two protrusions 18t among plural protrusions 18t. At this moment, plural protrusions 18t partially overlap plural ribs 18t in a direction (front-rear direction DAB) parallel to the upper surface of base plate 201s and perpendicular to pull-out direction D501. In this configuration, even if a this product is placed on the upper surface of plate body 201, that is, on the upper end of rib 201w, the product hits at least one of plural protrusions 18t when plate body 201 moves in pull-out direction D501, and is prevented from sliding out of internal space 501a from insertion slit 18. In accordance with Embodiment 1, viewing in front-rear direction DAB, plural protrusions 18t overlap plural ribs 201w by width L116 in up-down direction DEF. Gap L115 in up-down direction DEF between the upper surface of base plate 201s of plate body 201 and upper inner edge 18a of insertion slit 18, is larger than width L116. The lower ends of multiple protrusions 18t are separated from the upper surface of base plate 201s of plate body 201.

Outer edge 2201 of plate body 201 facing side wall 114b of main basket body 1a is recessed by depth L2201 to deepest point 2201d in pull-out direction D501 (right direction DD). In other words, a distance from both ends of plate body 201 in front-rear direction DAB to deepest point 2201d in left-right direction DCD is depth L2201. Depth L2201 is smaller than a depth of groove 114g in left-right direction DCD. Outer edge 2201 fits into groove 114g when plate body 201 closes lower opening 12a.

In the case that outer edge 2201 of plate body 201 between both ends of plate body 201 has a straight shape, if plate body 201 warps in up-down direction DEF, outer edge 2201 of plate body 201 may not fit into groove 114g provided in side wall 114b even when plate body 201 is moved in left direction DC along grooves 3g to close lower opening 12a. This may prevents plate body 201 from completely close lower opening 12a. In shopping basket 551, outer edge 2201 of plate body 201 that fits into groove 114g is concave in right direction DD. Hence, even if plate body 201 warps in up-down direction DEF, outer edge 2201 of plate body 201 is surely inserted by being guided by groove 114g from both ends of outer edge 2201. Accordingly, lower opening 12a can be surely closed even if plate body 201 warps in up-down direction DEF. In shopping basket 551 according to Embodiment 1, outer edge 2201 of plate body 201 extends linearly from both ends of outer edge 2201 to deepest point 2201d, and deepest point 2201d is at a center of outer edge 2201 in front-rear direction DAB. In other words, viewing in up-down direction DEF, each of outer edges 2201, 3201, and 4201 of plate body 201 has an M shape. Within the area from both ends of outer edge 2201 of plate body 201 to deepest point 2201d, plate body 201 may curve from both ends of outer edge 2201 to deepest point 2201d.

As illustrated in FIGS. 6 and 8, through-holes 291 are provided in side walls 114a, 114b, 117a, and 117b. In shopping basket 551 according to Embodiment 1, through-hole 291 has a circular shape having a diameter ranging from 2 mm to 5 mm. This configuration can reduce the weight of shopping basket 551 while products stored in internal space 501a are prevented from falling out from through-hole 291 even when the products are small. Shopping baskets 501 and 511 may also have plural through-holes 291 in side walls 14, 14a, 17, and 17a, providing the same effects.

The structure of locking plate body 201 onto main basket body 1a when plate body 201 closes lower opening 12a will be described below. In order to lock by hooking a part of plate body 201 onto main basket body 1a, a complex structure for releasing the lock is required in the bottom driving device. In shopping basket 551 according to Embodiment 1, plate body 201 is locked to main basket body 1a by magnetic force of a magnet.

FIG. 11 is an enlarged view of part BB of shopping basket 551 illustrated in FIG. 8. FIG. 12 is a cross-sectional view of shopping basket 551 along line XVII-XVII illustrated in FIG. 11. Plate body 201 has side wall 1201a extending in downward direction DF from outer edge 1201. Shopping basket 551 includes yoke 612 embedded inside side wall 1201a of plate body 201, magnet 611 embedded inside side wall 1201a, and yoke 613 embedded in main basket body 1a. Magnet 611 has surfaces 611a and surface 611b opposite to surface 611a. Surface 611a is positioned in left direction DC of yoke 612 and contacts yoke 612. Surface 611b of magnet 611 is exposed in left direction DC. Yoke 613 is positioned in downward direction DF from lower inner edge 18b of insertion slit 18 of main basket body 1a. Yoke 613 has surface 613a exposed in right direction DD. When plate body 201 closes lower opening 12a completely, surface 611b of magnet 611 contacts surface 613a of yoke 613, and is fixed to yoke 613 by magnetic force of magnet 611. Thus, plate body 201 is locked to main basket body 1a.

As illustrated in FIG. 12, magnet 611 is polarized in front-rear direction DAB to have magnetic poles 611p 611q aligned in front-rear direction DAB and having opposite polarities. When surface 611b of magnet 611 contacts surface 613a of yoke 613, magnetic flux generated in one of magnetic poles 611p and 611q passes through yokes 612 and 613, and enters the other of magnetic poles 611p and 611q forms a closed magnetic circuit, and substantially does not exit yokes 612, 613. This configuration causes magnet 611 to be firmly fixed by yoke 613, and causes plate body 201 to be firmly locked onto main basket body 1a. Hence, plate body 201 can be prevented from accidentally opening lower opening 12a during shopping by the user. Since the magnetic flux substantially does not leak from yokes 612 and 613, magnetic influence on the products inside internal space 501a can be prevented.

FIG. 13A is an enlarged view of part CC of shopping basket 551 illustrated in FIG. 6. As illustrated in FIGS. 12 and 13A, recess 2114a is provided between the lower end of side wall 114a and lower inner edge 18b of insertion slit 18. Side wall 1201a of plate body 201 is exposed from recess 2114a. When plate body 201 closes lower opening 12a completely, magnet 611 contacts surface 613a of yoke 613. The bottom driving device has a claw that enters recess 2114a from below, hooks side wall 1201a of plate body 201, and urges side wall 1201a in right direction DD. Length W11 of recess 2114a in front-rear direction DAB is larger than the width of the claw in front-rear direction DAB of the bottom driving device, and smaller than the width of a finger. This configuration disables a finger to be inserted into recess 2114a from below and to be hooked on side wall 1201a of plate body 201. Hence, it is possible to suppress movement of plate body 201 locked onto main basket body 1a in right direction DD with the finger, and avoid opening of lower opening 12a.

Yokes 612 and 613 are made of magnetic metal, and have high strength. As illustrated in FIG. 11, yoke 612 embedded in plate body 20 extends from side wall 1201a of plate body 201 to base plate 201s. Accordingly, since yoke 612 having high strength extends from side wall 1201a to base plate 211s, side wall 1201a is connected to base plate 201s firmly, and strength of side wall 1201a itself can be increased. As illustrated in FIG. 12, yoke 613 embedded in main basket body 1a extends from one part to the other on both sides of recess 2114a of side wall 114a while passing through recess 2114a. This configuration increases strength of a part of side wall 114a that is thin because of recess 2114a. Yokes 612 and 613 thus increase the strength of shopping basket 551.

FIG. 13B is a partial enlarged view of still another shopping basket 561 according to Embodiment 1. In FIG. 13B, components identical to those of shopping basket 551 illustrated in FIGS. 5 to 13A are denoted by the same reference numerals. Shopping basket 561 illustrated in FIG. 13B is different from shopping basket 551 illustrated in FIGS. 5 to 13A in a structure connecting main basket body 1a to plate body 201. FIG. 13B illustrates this structure. In shopping basket 551 illustrated in FIGS. 5 to 13A, groove 114g into which outer edge 2201 of plate body 201 is inserted is provided in side wall 114b of main basket body 1a, and grooves 3g into which outer edges 3201 and 4201 of plate body 201 are inserted are provided in side walls 117a and 117b of main basket body 1a. In shopping basket 561 illustrated in FIG. 13B, protrusion 114t is provided in side wall 114b of main basket body 1a, and protrusions 3t are provided in side walls 117a and 117b. Groove 2201g into which protrusion 114t of side wall 114b of main basket body 1a is inserted is provided in outer edge 2201 of plate body 201, while grooves 3201g and 4201g into which protrusions 3t of side walls 117a and 117b of main basket body 1a are inserted are provided in outer edges 3201 and 4201 of plate body 201, respectively. This structure allows main basket body 1a to be connected with plate body 201 as in shopping basket 551 illustrated in FIG. 5, and provides similar effects.

In shops, plural unused shopping baskets are stacked while an upper shopping basket is stored in an internal space of a lower shopping basket. To increase the number of the stacked shopping baskets, the side walls preferably have angles than a right angle with respect to the bottom part. On the other hand, to take out products inserted from upper opening 11 of the shopping basket through lower opening 12a easily, the size of lower opening 12a is preferably close to that of upper opening 11, that is, the side walls have angles close to a right angle with respect to the bottom part. If the shopping basket is formed for easily taking out products from lower opening 12a, the number of the stacked shopping baskets is reduced. Hence, the angle between the plate body and each of the side walls is optimized in consideration of easily taking out products from lower opening 12a, and an increase of the number of the stacked shopping baskets.

In shopping basket 501 illustrated in FIGS. 1 to 3D, plate body 22 is stored inside side wall 14, and therefore, hardy provide thin side wall 14. Additionally, to store plate body 22 smoothly inside side wall 14, the bottom part and side walls need to be connected with smooth curves, thereby the shape and the angles of the side walls are limited to some extent, and the angle between the plate body and each of the side walls may not be optimized. In shopping baskets 511, 551, and 561 illustrated in FIGS. 4A to 13B, nothing is stored inside side walls 14a, and 17a, and the angle with the bottom part (plate body 201) can be set arbitrarily. Hence, the angle between the plate body and each of the side walls can be optimized in consideration of easily taking out products from lower opening 12a and an increase in the number of the stacked shopping baskets.

(2) Exemplary Embodiment 2

FIGS. 14A to 14C are perspective views of shopping basket 521 according to Exemplary Embodiment 2. FIG. 14D is a partial enlarged view of shopping basket 521 illustrated in FIG. 14B. FIGS. 15A to 15C are side views of shopping basket 521 according to Embodiment 2. In FIGS. 14A to 15C, components identical to those of shopping basket 501 illustrated in FIGS. 1 to 3D are dented by the same reference numerals.

(2-1) Detail

As illustrated in FIG. 14A, shopping basket 521 according to Embodiment 2 includes bottom part 2b that can open lower opening 12 of main basket body 1, instead of bottom part 2 of shopping basket 501 illustrated in FIGS. 1 to 3D.

Bottom part 2b includes two rotatable bodies 25a and 25b, and interlocking mechanism 8 that operate two rotatable bodies 25a and 25b together interlocking each other.

As illustrated in FIG. 15A, rotatable body 25a is divided into segment bodies 26a and 26b. Segment bodies 26a and 26b are connected to main basket body 1 via axis part 191. Axis part 191 has axes 91 and 92. Segment bodies 26a and 26b that constitute rotatable body 25a are connected at axis 91 of axis part 191. Segment bodies 26a and 26b are rotatable about axis 91.

As illustrated in FIG. 15A, rotatable body 25b is divided into segment bodies 26c and 26d. Segment bodies 26c and 26d are connected to main basket body 1 via axis part 191. Segment bodies 26c and 26d that constitute rotatable body 25b are connected at axis 92 of axis part 191. Segment bodies 26c and 26d are rotatable about axis 92.

Axis 91 is provided at a position along the edge of rotatable body 25a in rear direction DB when rotatable bodies 25a and 25b close lower opening 12, that is, at an end of rotatable body 25a facing rotatable body 25b. Axis 92 is provided at a position along the edge of rotatable body 25b in front direction DA, that is, at an end of rotatable body 25b facing rotatable body 25a. Here, “end” refers to a region having a predetermined width in front-rear direction DAB. When rotatable bodies 25a and 25b rotate, lower ends of rotatable bodies 25a and 25b move substantially in lateral direction DL.

Each of segment bodies 26a and 26b includes bottom plate 27a and two wall plates 28a that stand in upward direction DE from both ends of bottom plate 27a in front-rear direction DAB. Bottom plate 27a has a lower surface having an arcuate shape. An outer surface of bottom plate 27a has an arcuate shape curving about around axis 91. Wall plate 28a has a fan shape having a width gradually decreasing from bottom plate 27a toward axis 91. Each of segment bodies 26c and 26d includes bottom plate 27b and two wall plates 28b that stand in upward direction DE from both ends of bottom plate 27b in front-rear direction DAB. Bottom plate 27b has a lower surface having an arcuate shape An outer surface of bottom plate 27b has an arcuate shape curving about axis 92. Wall plate 28b has a fan shape having a width gradually decreasing from bottom plate 27b toward axis 92.

Segment body 26b is located below segment body 26a when bottom part 2b closes lower opening 12. A length of bottom plate 27a of segment body 26a in front-rear direction DAB is smaller than a length of bottom plate 27a of segment body 26a in front-rear direction DAB. The length of wall plate 28a of segment body 26a is smaller than the length of wall plate 28a of segment body 26a. Accordingly, when segment body 26b rotates and moves in upward direction DE, a part of segment body 26a overlapping segment body 26b increases, and segment body 26a is inserted on an inner side of segment body 26b, that is, is positioned between segment body 26b and internal space 501a. Segment body 26b is located below segment body 26a, when bottom part 2b closes lower opening 12. The length of bottom plate 27b of segment body 26c in front-rear direction DAB is smaller than the length of bottom plate 27b of segment body 26c in front-rear direction DAB. The length of wall plate 28b of segment body 26c is smaller than the length of wall plate 28b of segment body 26c. Accordingly, when segment body 26d rotates and moves in upward direction DE, a part of segment body 26c overlapping segment body 26d increases, and segment body 26c is inserted on the inner side of segment body 26d, that is, is positioned between segment body 26d and internal space 501a. Thus, lower opening 12 opens.

Interlocking mechanism 8 includes gear parts 81a and 81b and case 83 accommodating gear parts 81a and 81b therein. Gear part 81a is provided at upper ends of wall plates 28a and 28b of segment bodies 26a and 26c. Gear part 81b is provided at upper ends of wall plates 28a and 28b of segment bodies 26b and 26d. Gear parts 81a and 81b of rotatable body 25a are engaged with gear parts 81a and 81b of rotatable body 25b, and rotate synchronously with gear parts 81a and 81b in different directions, respectively. That is, gear part 81a of segment body 26a of rotatable body 25a is engaged with gear part 81a of segment body 26c of rotatable body 25b, and rotates synchronously with gear part 81a in a different direction. Gear part 81b of segment body 26c of rotatable body 25a is engaged with gear part 81b of segment body 26d of rotatable body 25b, and rotates synchronously with gear part 81b in a different direction.

As illustrated in FIG. 14D, hooking protrusion 82 protruding toward internal space 501a is provided on the edge of segment body 26b facing internal space 501a in front-rear direction DAB. Segment body 26b is moved in upward direction DE so as to open lower opening 12, hooking protrusion 82 contacts segment body 26a, and thereby, moves segment body 26a following the movement of segment body 26b. Similarly to hooking protrusion 82, a hooking protrusion protruding toward internal space 501a is provided on the edge of segment body 26d facing internal space 501a in front-rear direction DAB. When segment body 26d is moved in upward direction DE so as to open lower opening 12, this hooking protrusion contacts segment body 26c, and thereby, moves segment body 26c following the movement of segment body 26b.

While rotatable bodies 25a and 25b close lower opening 12, legs 29a and 29b are provided on lower ends of rotatable bodies 25a and 25b, respectively. While rotatable bodies 25a and 25b close lower opening 12, legs 29a and 29b form leg base 29. When shopping basket 521 is placed on mounting surface 71a, leg base 29 stands on mounting surface 71a. Hence, shopping basket 521 is stably supported by mounting surface 71a.

As illustrated in FIG. 15C, while lower opening 12 opens, leg base 29 contacts a peripheral part of lower opening 12 of main basket body 1 so as to prevent rotation of rotatable bodies 25a and 25b in upward direction DE, thus functioning as a rotation stopper configured to prevent the rotation of rotatable bodies 25a and 25b in upward direction DE. Accordingly, even if rotatable bodies 25a and 25b spring up to open lower opening 12, shopping basket 521 prevents excessive rotation of rotatable bodies 25a and 25b about axis part 191 inside main basket body 1.

When a pair of rotatable bodies 25a and 25b rotate in directions away from each other while products are stored in internal space 501a of shopping basket 521 according to the embodiment and are placed on mounting surface 71a, the weight of shopping basket 521 causes segment bodies 26a and 26b to rotate in opening directions, and causes hooking protrusion 82 to contact the edge on the center in the front-rear direction of segment bodies 26a and 26c. Further, when segment bodies 26b and 26d rotate in directions separating away from each other and opening, in conjunction to this, segment bodies 26a and 26c rotate in directions separating away from each other and opening, and open lower opening 12.

Axes 91 and 92 are provided along the center in front-rear direction DAB. For this reason, lower ends of the pair of rotatable bodies 25a and 25b move in lateral direction DL. As a result, shopping basket 521 according to the embodiment can move rotatable bodies 25a and 25b in directions opening rotatable bodies 25a and 25b without lifting up main basket body 1.

(2-2) Advantageous Effect

In shopping basket 521 according to the embodiment, bottom part 2b includes a pair of rotatable bodies 25a and 25b on which products can be placed. The pair of rotatable bodies 25a and 25b are rotatable in different directions about the axis part with respect to main basket body 1. In this configuration, when the pair of rotatable bodies 25a and 25b are opened, the weight of shopping basket 521 can move rotatable bodies 25a and 25b in opening directions.

In shopping basket 521 according to the embodiment, bottom part 2b includes rotatable body 25a axially supported by axis 91, and includes rotatable body 25b axially supported by axis 92. When two rotatable bodies 25a and 25b close lower opening 12, axis 91 is provided at an end of rotatable body 25a facing rotatable body 25b, and axis 92 is provided at an end of rotatable body 25b facing rotatable body 25a. In this configuration, even when rotatable bodies 25a and 25b move in opening directions, rotatable bodies 25a and 25b move in lateral direction DL. Hence, the process of lifting up main basket body 1 can be eliminated.

In addition, in shopping basket 521 according to the embodiment, rotatable body 25a is divided into plural segment bodies 26a and 26b, and rotatable body 25b is divided into plural segment bodies 26c and 26d. When rotatable bodies 25a and 25b rotate in directions separating away from each other, segment bodies 26a and 26b open lower opening 12 while overlapping each other, and plural segment bodies 26c and 26d open lower opening 12 while overlapping each other. In this configuration, even when two rotatable bodies 25a and 25b rotate in opening directions, segment bodies 26a and 26b move in upward direction DE while overlapping each other, and segment bodies 26c and 26d move in upward direction DE while overlapping each other. Hence, segment bodies 26a to 26d can be stored preferably in main basket body 1.

In shopping basket 521 according to the embodiment, two rotatable bodies 25a and 25b rotate synchronously with each other in different directions. In to this configuration, two rotatable bodies 25a and 25b can be opened and closed by moving only one rotatable body of two rotatable bodies 25a and 25b.
