Description

Article storage container

Technical Field

The present invention relates to a small article storage container that can be used standing on a table and is easy to carry.

Background

The following patent documents disclose a storage container suitable for storing a relatively long rod-shaped small article, such as a writing instrument, a glue stick (japanese: 1247386\124511248312463paste), a cosmetic brush, a fork, a spoon, and the like. When the small articles stored in the storage container are taken out for use, the fastener (e.g., a zipper) is opened to open the side wall and expose the storage space therein. In this state, the storage container can be placed on a top plate of a desk (desk), a table (table), or the like and can stand by itself, and therefore, the small rod-shaped articles can be smoothly taken in and out of the storage space. When carrying small articles, only the two side walls are folded and the joint is closed.

In order to facilitate storage of small rod-shaped articles, front plates (or walls) that are expanded so as to connect the front edges are provided at the front edges of the two side walls of the storage container. The front plate takes on the following roles: when the container is self-standing, the small articles standing in the storage space are prevented from falling to the front side and falling out of the storage space. Therefore, the vertical dimension of the front plate is large (actually, more than 70 mm), the upper end edge of the front plate is high, and the storage space becomes a deep bottom.

It is needless to say that small stationery and other objects not having a bar shape can be stored in the storage container. However, the articles are not always easy to be taken and placed due to the high front plate, and the visibility of the stored articles from the front may be reduced due to the front plate being blocked.

Problems to be solved by the invention

The present invention provides a container which is easy to take and place small articles, especially non-rod-shaped articles, and has good visibility of the small articles.

Means for solving the problems

In the present invention, a container for small articles is configured, the container including: a pair of side walls which form a storage space for storing small articles between the facing inner surfaces, are connected at rear edge portions in an openable and closable manner, and can take a retracted posture in which the side walls are close to each other and an extended posture in which the side walls are opened to open the storage space forward and can stand on a table in this state; and a rack (japanese: booth) that is provided in the storage space, that flexes in the collapsed position, and that expands in the expanded position, and that can mount thereon small objects that are not rod-shaped, and that can be viewed from the front.

The bridge may be disposed at a position that floats upward from a lower edge of the storage space in the expanded posture.

In addition, in the expanded posture, the rack may be provided in a plurality of stages in the vertical direction in the housing space.

A fall prevention portion may be attached to a front end portion of the frame, the fall prevention portion being flexed in the collapsed posture and expanded in the expanded posture to be raised upward from an upper surface of the frame.

The front end portion of the rack disposed at a position floating upward from the lower edge of the storage space in the expanded posture may be provided with a reinforcing portion having higher rigidity than a portion of the rack on which the small object is placed.

The reinforcement portion is formed by, for example, tucking a portion where the frame and the drop preventing portion intersect.

Preferably, the fall prevention unit attached to the rack disposed at a position corresponding to a lower edge of the storage space in the expanded posture is folded so as to be convex forward in a process of shifting from the expanded posture to the contracted posture.

Preferred embodiments include the following: the rack is provided with a partition wall that divides the storage space into left and right in the expanded posture, the rack is provided in one of the storage spaces divided by the partition wall, and a space region for storing a small bar-shaped object is secured in the other storage space.

Further, if one engaging piece is provided for coupling the front edge portions of the pair of side walls to each other in the retracted posture, a space region having a shelf and adapted to receive small objects other than rod-shaped small objects and a space region adapted to receive small objects in rod-shaped small objects can be simultaneously opened by an operation of opening the engaging piece. Also, by the operation of closing the joint, two spatial regions can be closed at the same time.

Detailed Description

An embodiment of the present invention will be described with reference to the drawings. Fig. 1 to 7 show a small article storage container according to the present embodiment. The storage container of the present embodiment has a storage space 6 formed between a pair of openable and

closable side walls

1 and 2 connected to a rear edge portion via a back wall 3 serving as a connecting portion, and capable of storing small articles.

The storage container can take a contracted posture in which the storage space 6 is closed by approaching the inner surfaces of the

side walls

1 and 2 to face each other, and an expanded posture in which the storage space 6 is opened by opening the

side walls

1 and 2 to be spaced apart. When the storage container takes the collapsed posture, the left and

right side walls

1, 2 and the back wall 3 are substantially shaped like a letter 12467in a plan view or a bottom view. The back wall 3 is a flexible hinge for relatively rotating one side wall 1 with respect to the other side wall 2. The height of the lower edges of the

side walls

1, 2 coincides with the height of the lower edge of the back wall 3. In the expanded posture shown in fig. 1 and 2, the lower edges of the left and

right side walls

1 and 2 and the back wall 3 which are opened are placed on a top plate of a desk, a table, or the like, and the storage container can be made to stand upright while the storage space 6 is opened forward.

Each of the

side walls

1 and 2 includes a

panel

11 and 21 that shields the storage space 6 from the outside, and a

gusset

12 and 22 that extends from the edge of the

panel

11 and 21 toward the inside, which is a direction in which they approach each other. The

front parts

121, 221 of the

strips

12, 22 are connected to the front edge of the

panels

11, 21, and the

upper parts

122, 222 of the

strips

12, 22 are connected to the upper edge of the

panels

11, 21. The

rear portions

123, 223 of the

gores

12, 22 are connected to the rear edge portions of the

panels

11, 21 at positions above the back wall 3 connecting the

panels

11, 21 to each other. The front 121, 221, upper 122, 222, rear 123, 223, and back wall 3 of the

gores

12, 22 are continuous, and shield the housing space 6 from the front, upper, and rear in the contracted state shown in fig. 3 and 4.

The storage container is provided with one joint 4, and the joint 4 can connect the upper parts of the front edge part, the upper edge part and the rear edge part of the two

side walls

1 and 2 in the contraction posture. As is well known, the fastener 4 includes a pair of elements 412 and 422 (elements) connected to inner edges of the end edges of the

strips

12 and 22 of the

side walls

1 and 2 via

tapes

411 and 421, and a slider 43 for engaging and disengaging the

elements

412 and 422. The

coupling elements

412, 422 of the coupling piece 4 extend over the

front part

121, 221, the

upper part

122, 222 and the

rear part

123, 223 of the

gores

12, 22. The upper stop 44 of the joint 4 is located at the lower end of the

front part

121, 221 of the

strip

12, 22 and the lower stop 45 is located at the lower end of the

rear part

123, 223 of the

strip

12, 22, in other words at the upper end of the back wall 3.

When the slider 43 of the fastener 4 is moved from the lower stop 45 to the upper stop 44 in the retracted position, the

coupling elements

412 and 422 on both sides are engaged with each other to close the fastener 4, and the gores 12 of one side wall 1 and the gores 22 of the other side wall 2 cannot be separated from each other. That is, the storage space 6 is kept closed, and the storage container can be carried and transported without dropping the small articles stored in the storage space 6. Conversely, if the slider 43 is moved from the upper stop 44 to the lower stop 45, the

engaging elements

412 and 422 on both sides are separated, the fastener 4 is opened, and the strip 12 of one side wall 1 and the strip 22 of the other side wall 2 can be separated. Then, the one side wall 1 is turned relative to the other side wall 2 to shift from the contracted posture to the expanded posture, and the storage space 6 is opened to allow the small articles to be taken in and out.

The width of the gores 12 connected to one side wall 1 is larger than the width of the gores 12 connected to the other side wall 2. That is, the fastener 4 is located on the other side of the center of the width dimension of (the back wall 3 of) the storage container. The width of the back wall 3 is equal to the sum of the width of the

gores

12 and 22 on both sides and the width of (the

bands

411 and 421 and the

coupling elements

412 and 422 of) the fastener 4.

A handle (or a grip or a handle) 13 is provided on the upper portion of the

side walls

1 and 2 of the storage container. The handle 13 is fixed to a portion where the upper edge of the panel 11 of one side wall 1 and the upper portion 122 of the gore 12 intersect. When the container set in the collapsed posture and having the fastener 4 closed is stored in a bag, a box, or another container, the handle 13 can be used to take out the container from the container by pinching the handle 13 with a finger.

As shown in fig. 2, in the expanded posture, the

upper regions

111 and 211 of the

panels

11 and 21 of the left and

right side walls

1 and 2 are respectively bent outward, and the

rear portions

123 and 223, the

upper portions

122 and 222, and the

front portions

121 and 221 of the

gores

12 and 22 connected to the

upper regions

111 and 211 are folded back outward, whereby the upper side of the storage space 6 can be opened. The

lower regions

112 and 212 of the

panels

11 and 21 are provided with core members and have higher rigidity than the

upper regions

111 and 211 and the

gores

12 and 22, but the

upper regions

111 and 211 are not necessarily provided with core members.

The storage space 6 inside the storage container is divided into left and right sides by a partition wall 5. One of the

space regions

61 and 62 is mainly used for accommodating small objects other than rods. The other space region 63 can be used mainly for accommodating small rod-shaped objects. When the storage container is used as a pen bag, long articles such as pens, other writing instruments, cutters, scissors, rulers, and glue sticks can be stored in the space region 63. In addition, other types of stationery, such as an eraser, a cartridge for a refill of a mechanical pencil, a relatively small transparent tape, a tape (japanese: 124861251254012503paste), a correction tape, and the like can be accommodated in the

space regions

61 and 62.

The partition wall 5 is a thin plate body that is erected with its rear edge portion attached to the inner surface of the back wall 3, i.e., facing the front. The partition wall 5 is provided with a core material to increase rigidity. The attachment position of the rear edge portion of the partition wall 5 along the width direction of the storage container is shifted to one side with respect to the center of the width dimension of the storage container, and substantially coincides with the position of the joint 4 interposed between the

gores

12, 22 on both sides. Thus, the inner dimension in the width direction, i.e., the volume, of one of the

spatial regions

61 and 62 is larger than the inner dimension in the width direction, i.e., the volume, of the other spatial region 63.

The vertical dimension of the partition wall 5 is smaller than the vertical dimension of (the

side walls

1, 2 of) the storage container. The upper edge of the partition wall 5 is located below the upper edge of the storage space 6, in other words, the

upper portions

122 and 222 of the

gores

12 and 22. The lower edge of the partition wall 5 is located at a height position equal to or slightly above the lower edges of the

side walls

1 and 2 and the back wall 3. The partition wall 5 has a front-rear dimension slightly smaller than the front-rear dimension of (the

side walls

1, 2 of) the storage container. When the joint 4 is closed in the collapsed position, the partition wall 5 is accommodated in the accommodation space 6 surrounded by the

panels

11 and 21 of the

side walls

1 and 2, the

gores

12 and 22, and the back wall 3, and is not exposed to the outside.

In the

space regions

61, 62 for storing small articles not in the shape of rods,

multi-layer shelves

71, 72 are provided in the vertical direction. Small objects other than rods can be placed on these

racks

71 and 72 in a lying manner. Each of the

racks

71 and 72 is a flexible member that is expanded to the left and right when the storage container takes the expanded posture as shown in fig. 1, 2, and 5, and is folded when the storage container takes the contracted posture as shown in fig. 3, 4, and 6. In the expanded posture, small objects can be placed on the

respective racks

71 and 72. The small articles placed on the

racks

71 and 72 can be easily viewed from the front of the storage container. One side end of the

brackets

71, 72 is attached to and supported by the inner surface of the panel 11 of the side wall 1. The other side end portions of the

brackets

71 and 72 are attached to and supported by the surface of the partition wall 5 facing the panel 11 of the side wall 1. The rear end of the lower rack 72 is attached to and supported by the front surface of the back wall 3.

The upper stage rack 71 is raised upward from the lower edges of the

space regions

61 and 62 for storing small articles that are not rod-shaped, in other words, the lower stage rack 72. That is, the space 62 below the rack 71 can be effectively used for storing small articles, not only above the rack 71. The upper shelf 71 is naturally located below the upper edges of the

space regions

61 and 62.

A fall prevention portion 711 that expands to the left and right in the expanded posture and stands upward from the upper surface of the upper stage frame 71 is attached to the front end portion of the upper stage frame 71. The fall prevention part 711 suppresses the small items placed on the rack 71 from falling from the rack 71. The fall prevention part 711 has flexibility to be folded together with the frame 71 in the collapsed posture. One side end of the drop preventing portion 711 is attached to and supported by the inner surface of the panel 11 of the side wall 1. The other side end of the drop preventing portion 711 is attached to and supported by a surface of the partition wall 5 facing the panel 11 of the side wall 1. That is, the fall prevention portion 711 couples the panel 11 of one side wall 1 and the partition wall 5 together with the upper stage frame 71. Both side ends of the drop preventing portion 711 are joined to the panel 11 and the partition wall 5 along the front edges of the panel 11 and the partition wall 5 of the side wall 1.

In order to ensure visibility of small articles placed on the rack 71 from the front, the drop prevention unit 711 has a relatively small vertical dimension, and the height of the upper end edge of the drop prevention unit 711 as viewed from the rack 71 is relatively low. In the present embodiment, the vertical dimension of the drop prevention part 711 of the upper stage rack 71 is set to about 30mm.

A reinforcement part 712 is provided at a portion where the upper stage frame 71 and the drop preventing part 711 intersect, that is, at a front end portion of the frame 71 and/or a lower end portion of the drop preventing part 711, and the reinforcement part 712 has flexibility and further improves rigidity as compared with a portion of the frame 71 where a small object is placed. The reinforcement portion 712 extends in the width direction along the front end portion of the upper stage frame 71 and the lower end portion of the drop prevention portion 711, and suppresses the upper stage frame 71 that has been expanded in the expanded posture from sagging (or sinking) downward.

The reinforcing portion 712 is formed, for example, by tucking a portion where the frame 71 and the drop prevention portion 711 intersect. That is, as shown in fig. 8, a frame 71 and a fall prevention portion 711 rising upward from the frame 71 are formed by a continuous sheet of cloth, leather, or the like. At this time, the sheet is bent so as to temporarily hang down at the front end portion of the frame 71, and then mountain-folded (convex-folded) is performed so as to rise again, and the drop prevention portion 711 is provided, and at this mountain-folded, sewing is performed by the sewing thread 713 (the sewing is advanced in the width direction along the convex fold line). With such a tucking, a structure such as a thin tuck (tuck or tuck) that extends in the width direction and is made by pinching a sheet appears at the front end portion of the frame 71 and the lower end portion of the drop preventing portion 711.

The reinforcing part 712 can also be formed by piping the part where the frame 71 and the drop preventing part 711 intersect. The binding is performed by wrapping the front end edge of the frame 71 and the lower end edge of the drop preventing part 711 with a bias tape (english: taping tape), or by interposing a child-mother tape (english: taping tape) wrapping the wire material to be the core between the front end edge of the frame 71 and the lower end edge of the drop preventing part 711 (thread binding or pinch stitching (japanese: 12399 \/1237312415. The bias cut tape or the sub-tape may be sewn to the material constituting the frame 71 and the fall preventing portion 711, or may be bonded or welded to the material constituting the frame 71 and the fall preventing portion 711.

Of course, the reinforcing portion 712 can be formed by a method other than creasing or hemming. For example, other methods may be considered, such as a method of sewing, bonding, or welding a core material that is elongated in the width direction, such as a front end portion of the frame 71 or a lower end portion of the drop preventing portion 711, and a method of attaching or incorporating an elastically deformable wire or spring, which is shaped like a rectangular shape in plan view, to the frame 71 so as to extend along the front end edge and the left and right end edges of the frame 71.

The lower shelf 72 is located at the lower edge of the

space regions

61, 62 and just becomes the bottom of the

space regions

61, 62. The lower shelf 72 is located at a height equal to or slightly above the lower edges of the

side walls

1 and 2 and the back wall 3. Both side end portions of the lower frame 72 are joined to the panel 11 and the partition wall 5 along the lower edges of the panel 11 and the partition wall 5 of the side wall 1. Further, the rear end portion of the lower shelf 72 is joined to the back wall 3 along the lower edge of the back wall 3.

Similarly to the upper stage frame 71, a drop preventing portion 721 which is expanded to the left and right in the expanded posture and stands upward from the upper surface of the frame 72 is also provided at the front end portion of the lower stage frame 72. The fall prevention portion 721 suppresses the small items placed on the rack 72 from falling from the rack 72. The fall prevention portion 721 has flexibility to be folded together with the frame 72 in the collapsed position. One side end of the drop preventing portion 721 is attached to and supported by the inner surface of the panel 11 of the side wall 1. The other side end of the drop preventing portion 721 is attached to and supported by a surface of the partition wall 5 facing the panel 11 of the side wall 1. That is, the fall inhibitor 721 connects the panel 11 of one side wall 1 and the partition wall 5 together with the lower frame 72. Both side ends of the fall inhibitor 721 are joined to the panel 11 and the partition wall 5 along the front edges of the panel 11 and the partition wall 5 of the side wall 1.

In order to ensure visibility of a small object placed on the rack 72 from the front, the vertical dimension of the drop preventing portion 721 is relatively small, and the height of the upper end edge of the drop preventing portion 721 as viewed from the rack 72 is relatively low. In the present embodiment, the vertical dimension of the fall preventing portion 721 of the lower stage frame 72 is set to about 45mm. Which is larger than the upper and lower size of the falling prevention part 711 of the upper stage shelf 71.

The gusset strips 12 and 22 are not present at the lower edge portions of the

side walls

1 and 2 of the storage container. Therefore, as shown in fig. 5 and 6, the lower shelf 72 is not hidden from view when viewed from below and can be visually recognized. As shown in fig. 6, when the engaging member 4 is closed in the contracted position, the front end portions of the

frames

71 and 72 and the

fall preventing portions

711 and 721 that are bent and deformed and folded, and the front edge of the partition wall 5 abut against or come very close to the rear surface of the inner surfaces of the

front portions

121 and 221 of the

gores

12 and 22.

If a gap is formed between the falling prevention portion 721 of the folded lower frame 72 and the rear surface of the

front portions

121 and 221 of the

gores

12 and 22 in the collapsed position, small articles stored in the gap may fall off. Therefore, in the storage container of this embodiment, as shown in fig. 7, in the process of the relative rotation of the expanded one side wall 1 toward the partition wall 5 and the panel 21 of the other side wall 2 in the process of the transition from the expanded posture to the contracted posture, that is, in the process of the approach of the expanded one side wall 1 toward the partition wall 5, the drop preventing portion 721 of the lower stage frame 72 is folded into the mountain fold shape convex forward, and conversely, the fold is given to the drop preventing portion 721 so that the drop preventing portion 721 is folded into the valley fold shape concave rearward and does not enter the

space regions

61 and 62. Specifically, the substantially V-shaped stitches 722 or creases are placed in the fall prevention section 721 in front view, the fall prevention section 721 is bent along the stitches 722 or creases, and the center of the fall prevention section 721 located inside the stitches 722 or creases is projected forward.

Instead of such stitches 722, it is also conceivable to provide creases so that the drop preventing portions 721 of the lower frame 72 are folded into a mountain-fold shape protruding forward by forming a thin crease extending in the vertical direction by sewing at the center portion in the width direction of the drop preventing portions 721.

Conversely, the

racks

71 and 72 are not provided in the space area 63 for storing the small rod-shaped articles. This is to ensure a large space extending from the upper edge to the lower edge of the storage container, and to enable small long articles to be stored appropriately.

A bottom plate 81 serving as a bottom of the space region 63 is provided at a position corresponding to a lower edge of the space region 63. The bottom plate 81 is located at a height position equal to or slightly above the lower edges of the

side walls

1 and 2 and the back wall 3. The bottom plate 81 is a flexible member that is expanded to the left and right when the storage container takes the expanded posture as shown in fig. 1, 2, and 5 and is folded when the storage container takes the contracted posture as shown in fig. 3, 4, and 6, and supports a small rod-shaped object stored in the space region 63. One side end of the bottom plate 81 is attached to and supported by a surface of the partition wall 5 facing the panel 21 of the side wall 2. The other side end of the bottom plate 81 is attached to and supported by the inner surface of the panel 21 of the side wall 2. Both side end portions of the bottom plate 81 are joined to the face plate 21 and the partition wall 5 along the lower edges of the face plate 21 and the partition wall 5 of the side walls 2. The rear end of the bottom plate 81 is attached to and supported by the front surface of the back wall 3. The rear end portion of the bottom plate 81 is joined to the back wall 3 along the lower edge of the back wall 3.

A front plate 82 that is expanded to the left and right in the expanded posture and that rises upward significantly above the upper surface of the bottom plate 81 is attached to the front end of the bottom plate 81. The front plate 82 has flexibility to fold together with the chassis 81 in the retracted position. One side end of the front plate 82 is attached to and supported by a surface of the partition wall 5 facing the panel 21 of the side wall 2. The other side end of front plate 82 is attached to and supported by the inner surface of panel 21 of side wall 2. That is, the front plate 82 connects the panel 21 of the other side wall 2 to the partition wall 5 together with the bottom plate 81. Both side ends of the front plate 82 are joined to the panel 21 and the partition wall 5 along the front edges of the panel 21 and the partition wall 5 of the side wall 2.

In order to prevent the small rod-shaped articles accommodated in the space region 63 from falling out of the space region 63 by falling forward, the vertical dimension of the front plate 82 is relatively large, and the height of the upper end edge of the front plate 82 as viewed from the bottom plate 81 is relatively high. In the present embodiment, the vertical dimension of the front plate 82 is set to about 70mm or more (approximately 80 mm). Which is larger than the vertical size of the

fall prevention parts

711, 721 of the

racks

71, 72.

A thin sheet-like or net-like pocket member 821 is attached to the front surface of the front plate 82, and a pocket into which an article can be inserted from above is formed between the pocket member 821 and the front plate 82. The left and right side end portions of the pocket member 821 are joined to the front surface of the side end portion of the front plate 82, and the lower end portion of the pocket member 821 is joined to the front surface of the lower end portion of the front plate 82.

Incidentally, a thin sheet-like or net-like pocket member 24 can also be attached to the outer surface of the panel 21 of the side wall 2, and a pocket into which an article can be inserted from above can be formed between the pocket member 24 and the panel 21. The pocket is exposed to the outside even when the storage container takes the collapsed posture, and the article can be taken and placed without opening the fastener 4. The front end, the rear end, and the lower end of the pocket member 24 are attached to and supported by the outer surface of the panel 21 of the side wall 2. It is of course also possible to provide the same pocket on the outer surface of the panel 11 of the side wall 1.

Further, a belt 23 that expands and contracts by elastic deformation is attached to the inner surface of the panel 21 of the side wall 2, and an article can be sandwiched between the belt 23 and the panel 21. The front end and the rear end of the belt 23 are attached to and supported by the front end and the rear end of the panel 21.

Each part of the storage container, that is, the

panels

11 and 21 of the

side walls

1 and 2, the

gores

12 and 22, the partition plates, the

frames

71 and 72, the

fall preventing portions

711 and 721, the bottom plate 81, and the front plate 82 can be formed of cloth, resin film, leather, or the like. The core member may be formed of a thin plate of a harder resin or the like. The respective portions of the storage container may be joined by sewing, or may be joined by adhesion, welding, or the like.

In the present embodiment, a small article storage container is configured, the container including: a pair of

side walls

1, 2, the pair of

side walls

1, 2 forming a storage space 6 for storing small articles between the facing inner surfaces, and being connected at the rear edge portion in an openable and closable manner, and being capable of assuming a retracted posture in which they are close to each other and an extended posture in which they are opened to open the storage space 6 forward and are capable of standing up on a table in this state; and racks 71, 72, the

racks

71, 72 being disposed in the storage space 6, being flexed in the contracted posture, being expanded in the expanded posture, being capable of placing thereon small articles that are not rod-shaped, and being capable of being visually recognized from the front.

According to the present embodiment, it is possible to realize a storage container having a storage space 6 in which small articles, particularly, articles other than rod-shaped articles can be easily taken and placed, and in which the small articles stored therein are excellent in visibility. When the storage container in the expanded posture is viewed from the front or the front and upper side, the rear region, which is the deep region of the

racks

71 and 72 of each floor, can be viewed well without being blocked by the

drop preventing portions

711 and 721, and therefore, small objects placed on the

racks

71 and 72 in a lying or lying manner can be easily visually recognized, and desired small objects can be easily found.

Since the rack 71 is provided at a position that floats upward from the lower edge of the storage space 6 in the expanded posture, the space region 62 below the rack 71 can be effectively used for storing small articles.

The

shelves

71 and 72 are provided in a plurality of stages in the vertical direction in the storage space 6 in the expanded posture, and the

shelves

71 and 72 in the respective stages can be used for storing small articles.

Since the falling

prevention portions

711 and 721 that are bent in the contracted posture, expanded in the expanded posture, and raised upward from the upper surfaces of the

racks

71 and 72 are provided at the distal end portions of the

racks

71 and 72, the small objects on the

racks

71 and 72 can be prevented from falling from the

racks

71 and 72. In order to prevent the small objects on the

racks

71 and 72 from being blocked by the

drop prevention parts

711 and 721 and to maintain the visibility of the small objects high, the vertical dimensions of the

drop prevention parts

711 and 721 are preferably about 45mm or less. In the present embodiment, the size of the

drop prevention parts

711, 721 is set to about 30mm to about 45mm.

If the reinforcing portion 712 having higher rigidity than the portion of the rack 71 on which the small items are placed is provided at the front end portion of the rack 71 that is disposed at a position that floats upward from the lower edge of the storage space 6 in the expanded posture, downward looseness of the rack 71 that has been expanded in the expanded posture can be suppressed, the space region 62 below the rack 71 is not pressed, the taking in and out of the small items with respect to the space region 62 is not hindered, and the visibility of the small items stored in the space region 62 is also maintained high. The reinforcement part 712 is formed by creasing a portion where the bracket 71 and the drop prevention part 711 intersect.

The drop preventing portion 721 attached to the rack 72 disposed at a position corresponding to the lower edge of the storage space 6 in the expanded posture is folded so as to be convex forward in the process of transition from the expanded posture to the contracted posture, and therefore, the drop preventing portion 721 of the lowest rack 72 in the contracted posture is prevented from being recessed rearward and entering the storage space 6. Therefore, the fall prevention portion 721 is less likely to interfere with the small articles stored in the lowermost rack 72 (i.e., the lower space region 62), and the small articles on the rack 72 are less likely to fall off when the storage container set in the collapsed posture is conveyed. In addition, even if a small article stored in the upper shelf 71 (i.e., in the upper space region 61) falls off from the upper shelf 71 during the transportation of the storage container, the small article is caught by the lowermost shelf 72 or the fall prevention section 721, and the so-called shelf 72 and the fall prevention section 721 become a tray or a cover and are prevented from falling off from the storage container.

Since the present invention is provided with the partition wall 5 that divides the storage space 6 into left and right in the expanded posture, the

racks

71, 72 are provided in one 61, 62 of the storage space 6 divided by the partition wall 5, and the space region 63 for storing the small rod-shaped objects is secured in the other 63, it is possible to appropriately store the small rod-shaped objects and the small rod-shaped objects together.

Further, since the single fastener 4 is provided for joining the front edge portions of the pair of

side walls

1 and 2 to each other in the retracted posture, the

space regions

61 and 62 having the

racks

71 and 72 and adapted to receive small objects other than rod-shaped small objects and the space region 63 adapted to receive small objects other than rod-shaped small objects can be simultaneously opened by the operation of opening the fastener 4. By closing the joint 4, the two

space regions

61, 62, 63 can be closed at the same time.

If the

joint pieces

12 and 22 expanding in the direction of approaching each other are provided at the front edge portions of the pair of

side walls

1 and 2 and the joint pieces 4 are provided at the end edge portions of the

joint pieces

12 and 22, the volume of the storage space 6 in the contracted state can be sufficiently secured.

Furthermore, the present invention is not limited to the embodiments described in detail above. For example, the storage container of the above embodiment includes one joint 4 that can open and close the storage space 6 and maintain the storage container in a contracted state. The partition wall 5 defining the

space regions

61 and 62 capable of storing the small articles not in the shape of a bar having the

shelves

71 and 72 and the space region 63 capable of storing the small articles in the shape of a bar having no

shelves

71 and 72 is housed in the housing space 6 in a contracted state and hidden by the

panels

11 and 21 of the

side walls

1 and 2, the

gores

12 and 22, and the back wall 3. However, as shown in fig. 9, a storage container may be configured to include two

engaging pieces

401, 402 independent of each other, one 401 opening and closing the

space regions

61, 62 having the

shelves

71, 72 in the storage space 6, and the other 402 opening and closing the space region 63 not having the

shelves

71, 72.

In the storage container of this modification, the latter space region 63 can be opened in a state where the

former space regions

61 and 62 are closed, and the

former space regions

61 and 62 can also be opened in a state where the latter space region 63 is closed. Of course, as shown in fig. 9, the storage container may be set to an expanded posture in which the two

sides

61, 62, 63 are opened, and set to stand on a table. In this modification, even in the contracted posture in which the two

joints

401 and 402 are closed, the

gores

501 and 502 of the partition wall 5 defining the two

space regions

61, 62 and 63 are exposed to the outside. The joint 401 for opening and closing the

former space regions

61 and 62 is interposed between the gores 12 of one side wall 1 and the gores 501 of the partition wall 5, and the joint 402 for opening and closing the latter space region 63 is interposed between the gores 22 of the other side wall 2 and the gores 502 of the partition wall 5.

The partition wall 5 does not necessarily have to divide the storage space 6 of the storage container. As shown in fig. 10, the storage container may be configured to be provided with

racks

701, 702, and 703 that expand over the entire area of the storage space 6 without providing the partition wall 5. In this case, both side ends of the

racks

701, 702, 703 are attached to and supported by the inner surfaces of (the

panels

11, 21 of) the left and

right side walls

1, 2, respectively.

The number of shelves provided in the housing space 6 is not limited to two. In the modification shown in fig. 10, three stages of

racks

701, 702, and 703 are provided in the upper and lower stages. In this case, the vertical dimension of the drop prevention portions 7031 of the lower rack 703 can be set larger than the vertical dimension of the

drop prevention portions

7011, 7021 of the

upper racks

701, 702.

As shown in fig. 11, a tab 13 may be provided which is not ring-shaped, i.e., which is not hollow at the center.

The number of layers of the shelf may be one. For example, it is conceivable to construct a storage container having only the

lowermost shelves

72 and 703, with the

upper shelves

71, 701, and 702 omitted from the above storage container.

The

fall preventing portions

711, 721, 7011, 7021, and 7031 that engage the front end portions of the

racks

71, 72, 701, 702, and 703 and rise upward from the upper surfaces of the

racks

71, 72, 701, 702, and 703 are not essential elements. In the case where the fall preventing portion is not provided at the front end portion of the rack, for example, in an expanded posture in which the storage container is raised, the rack may be inclined such that the front end portion of the rack is higher than the rear end portion of the rack. Alternatively, a rack may be provided that is flexibly or elastically deformed by a load received from a small article placed on the rack so that a portion directly below the small article sinks downward.

The

racks

71, 72, 701, 702, 703 may be mesh members or members having holes penetrating vertically through the racks.

The specific configuration of each part can be variously modified within a range not departing from the gist of the present invention.
