Summary of the Invention

Problem to be Solved by the Invention

[0005] In the bag of Patent Document 1, when used as a personal computer stand, the slide fastener provided on the outer peripheral portion of the bag body is closed. Therefore, the storage space inside the bag cannot be used while the bag is being used as a personal computer stand. Furthermore, when the bag is used as a personal computer stand, the handle protruding from the bag body is arranged in front of the personal computer, which becomes an obstacle when placing documents or the like.

[0006] Accordingly, an object of the present invention is to provide a bag that allows use of the internal storage space even when the bag is used as a personal computer stand. [Means for solving the problem]

[0007] The bag according to the present invention comprises a bag body formed in a concave shape with an opening, and a pair of handles connected to the bag body for use when carrying, wherein the pair of handles are each connected to the long edge of the opening, and the bag is configured to be able to assume a position in which the pair of handles are positioned along the outer circumferential surface of the bag body. The handle portion has approximately the same size as the outer surface of the bag body. It is characterized by the following:

[0008] This design allows the bag's opening to remain open even when used as a laptop stand, enabling access to the internal storage space. Furthermore, when used as a laptop stand, the handle is positioned along the outer edge of the bag, preventing it from obstructing documents or other items placed in front of the laptop. Furthermore, the computer can be placed on a surface without any steps or unevenness.

[0011] The bag according to the present invention comprises a bag body formed in a concave shape with an opening, and a pair of handles connected to the bag body for use when carrying, wherein the pair of handles are each connected to the long edge of the opening, and the bag is configured to be able to assume a position in which the pair of handles are positioned along the outer circumferential surface of the bag body. The handle portion is characterized by having a joint portion that is joined to the outer circumferential surface of the bag body on the long edge side of the opening, and a movable portion that is bendable at the first end of the joint portion opposite to the opening and has a handle hole formed therein.

[0012] This design allows the bag's opening to remain open even when used as a laptop stand, enabling access to the internal storage space. Furthermore, when used as a laptop stand, the handle is positioned along the outer edge of the bag, preventing it from obstructing documents or other items placed in front of the laptop. Also, This prevents the distance between the handle hole and the top edge of the bag from becoming too large when carrying the bag by gripping the handle hole with your fingers.

[0013] In the bag according to the present invention, it is preferable that the movable part has a first bent portion that bends along the long edge of the opening when it is bent at the first end and faces the outer circumferential surface of the joint.

[0014] Accordingly, the movable portion of the handle portion can be bent at the first bent portion to be used as a lid member that covers the opening.

[0015] In the bag according to the present invention, it is preferable that the movable portion has a second bent portion disposed on an opposite side to the first end portion with respect to the first bent portion, and the handle hole is disposed on an opposite side to the first bent portion with respect to the second bent portion.

[0016] Accordingly, when the bag has a pair of handle portions, the bag can be carried by gripping the handle holes with fingers in a state where the handle holes respectively formed in the pair of handle portions are brought close to each other.

[0017] The bag according to the present invention comprises a bag body formed in a concave shape with an opening, and a pair of handles connected to the bag body for use when carrying, wherein the pair of handles are connected to the long edge side of the opening, and the bag body is configured to be positioned such that the pair of handles are arranged along the outer circumferential surface of the bag body, wherein the bag body comprises a front sheet member, a back sheet member facing the front sheet member, and a left sheet member, a right sheet member, and a bottom sheet member connecting the front sheet member and the back sheet member, wherein the front sheet member and the back sheet member are formed of a core material and a flexible member having flexibility that covers the surface and back surface of the core material, wherein the left sheet member, the right sheet member, and the bottom sheet member are formed of a flexible member having flexibility, wherein reinforcing plates are arranged inside the bag body along the left sheet member, the right sheet member, and the bottom sheet member, and the reinforcing plates have mounting surface reinforcing portions that are arranged along the front sheet member in the aforementioned position.

[0018] This design allows the bag's opening to remain open even when used as a laptop stand, enabling access to the internal storage space. Furthermore, when used as a laptop stand, the handle is positioned along the outer edge of the bag, preventing it from obstructing documents or other items placed in front of the laptop. Also, By arranging reinforcing plates along the flexible left seat member, right seat member and bottom seat member, the shape of the bag as a personal computer stand can be properly maintained. Further, the bag body can be folded by bending the left seat member, the right seat member and the bottom seat member so that the inner side surface of the front seat member and the inner side surface of the back seat member approach each other. Furthermore, the increased rigidity of the laptop mounting surface prevents the surface from bending and causing the laptop to shake during use.

[0023] In the bag according to the present invention, it is preferable that the bag comprises a partition member disposed inside the reinforcing plate.

[0024] Accordingly, the storage space in the bag can be divided into a plurality of storage spaces for use.

[0025] In the bag according to the present invention, it is preferable that the partition member restricts a reduction in the distance between the reinforcing plate disposed along the left seat member and the reinforcing plate disposed along the right seat member.

[0026] This restricts the reduction in the distance between the reinforcing plate arranged along the left sheet member and the reinforcing plate arranged along the right sheet member, whereby the shape of the bag can be maintained more appropriately. In the bag according to the present invention, the handle portion is preferably formed of a core material and a flexible member having flexibility that covers the surface and back surface of the core material. This increases the rigidity of the laptop mounting surface, preventing the surface from bending and causing the laptop to shake during use. BRIEF DESCRIPTION OF THE DRAWINGS

[Figure 13] This figure illustrates the configuration of a bag 101 according to a modified embodiment of the present invention. [Modes for carrying out the invention]

[0028] The bag according to an embodiment of the present invention will be described in detail below with reference to the figures.

[0029] As shown in Figure 1, the bag 1 of this embodiment has a bag body 2 formed in a concave shape with an opening 2a. Handles 15 and 16 are attached to the upper end of the bag body 2, and the bag 1 is configured to be able to carry a laptop computer or the like inside. As shown in Figure 2, reinforcing parts 5 are arranged inside the bag body 2.

[0030] The bag body 2 includes a front sheet member 10, a back sheet member 11, a left sheet member 12, a right sheet member 13, and a bottom sheet member 14. The front sheet member 10 and the back sheet member 11 are horizontally elongated rectangles, while the left sheet member 12 and the right sheet member 13 are vertically elongated rectangles. The front sheet member 10 and the back sheet member 11 are positioned opposite each other. The left sheet member 12 connects the left end of the front sheet member 10 and the left end of the back sheet member 11, and the right sheet member 13 connects the right end of the front sheet member 10 and the right end of the back sheet member 11. The left sheet member 12 and the right sheet member 13 are positioned opposite each other.

[0031] The bottom sheet member 14 connects the lower end of the front sheet member 10, the lower end of the back sheet member 11, the lower end of the left sheet member 12, and the lower end of the right sheet member 13. As a result, the lower ends of the front sheet member 10, the lower end of the back sheet member 11, the lower end of the left sheet member 12, and the lower end of the right sheet member 13 are closed by the bottom sheet member 14, while the upper ends of the front sheet member 10, the upper end of the back sheet member 11, the upper end of the left sheet member 12, and the upper end of the right sheet member 13 form an opening 2a. In this way, a roughly rectangular parallelepiped storage space is formed inside the bag body 2.

[0032] The front sheet member 10 and the back sheet member 11 are formed from a core material and a flexible member (e.g., a covering material) that covers the front and back surfaces of the core material. The core material is, for example, cardboard or resin board, and the flexible member is, for example, a covering material such as polyester.

[0033] The left sheet member 12, the right sheet member 13, and the bottom sheet member 14 are made of flexible material such as polyester.

[0034] The bag body 2 has a pair of handles 15 and 16 connected to the upper end of the front sheet member 10 and the upper end of the back sheet member 11, respectively. The handles 15 and 16 are horizontally elongated rectangles, and handle holes 15a and 16a are formed near their upper ends for the user to grip with their fingers when carrying the bag 1.

[0035] As shown in Figure 3, when the handle portion 15 is positioned along the outer circumferential surface of the front sheet member 10, it has approximately the same size as the front sheet member 10. In this embodiment, "the handle portion 15 has approximately the same size as the front sheet member 10" means that the length of the handle portion 15 in the width direction (left-right direction) is approximately the same as the long side of the front sheet member 10 (or opening 2a), and the length of the handle portion 15 in the height direction (up-down direction) is approximately the same as the short side of the front sheet member 10. However, as in this embodiment, for example, the length of the handle portion 15 in the height direction may be slightly shorter than the short side of the front sheet member 10.

[0036] The handle portion 15 has a joint portion 151 that is joined to the long edge side of the opening 2a in the front sheet member 10, and a movable portion 152 that is positioned towards the tip side (downward in Figure 3) of the joint portion 151. The joint portion 151 is rectangular in shape and has approximately the same length as the long edge of the opening 2a, and its entire surface is joined to the outer circumferential surface of the front sheet member 10. Therefore, the joint portion 151 is integrated with the front sheet member 10.

[0037] The movable part 152 extends from the end 151a opposite to the opening 2a of the joint part 151, and a bent portion Ta1 is formed at the connection point between the movable part 152 and the joint part 151. Therefore, as shown in Figure 4, the movable part 152 is configured to be bent upward at the bent portion Ta1. The movable part 152 has a first movable part 152a, a second movable part 152b, and a third movable part 152c, which are arranged in order from the bent portion Ta1 side toward the tip side.

[0038] As shown in Figure 5, the first movable part 152a is the part that is stacked on the outer circumferential surface of the joint part 151 when the movable part 152 is bent at the bending part Ta1. Therefore, the first movable part 152a is approximately the same size as the joint part 151. A bending part Tb1 is formed at the connection between the first movable part 152a and the second movable part 152b. When the first movable part 152a faces the outer circumferential surface of the joint part 151, the bending part Tb1 is positioned along the long edge of the opening 2a. At that time, the second movable part 152b and the third movable part 152c can be positioned along the edge of the opening 2a so as to cover the opening 2a.

[0039] A bent portion Tc1 is formed at the connection between the second movable portion 152b and the third movable portion 152c. The bent portion Tc1 is positioned on the opposite side of the first end portion 151a relative to the bent portion Tb1. A handle hole 15a is formed in the third movable portion 152c. The handle hole 15a is positioned on the opposite side of the bent portion Tb1 relative to the bent portion Tc1.

[0040] The handle portion 16, like the handle portion 15, has a joint portion 161 that is joined to the long edge side of the opening 2a in the back sheet member 11, and a movable portion 162 that is positioned towards the front end (downward in Figure 6) of the joint portion 161, as shown in Figure 6. The joint portion 161 is rectangular in shape with approximately the same length as the long edge of the opening 2a, and its entire surface is joined to the outer circumferential surface of the back sheet member 11. Therefore, the joint portion 151 is integrated with the front sheet member 10.

[0041] The movable part 162 extends from the end 161a opposite the opening 2a of the joint 161, similar to the movable part 152 of the handle part 15, and a bent portion Ta2 is formed at the connection point between the movable part 162 and the joint 161. The movable part 162 has a first movable part 162a, a second movable part 162b, and a third movable part 162c, which are arranged in order from the bent portion Ta2 side toward the tip side. A bent portion Tb2 is formed at the connection point between the first movable part 162a and the second movable part 162b. A bent portion Tc2 is formed at the connection point between the second movable part 162b and the third movable part 162c. A detailed description of the movable part 162 is omitted, but it has the same configuration as the movable part 152 of the handle part 15.

[0042] The handle portions 15 and 16, like the front sheet member 10 and the back sheet member 11, are formed from a core material and a flexible member (e.g., a lining material) that covers the front and back surfaces of the core material. The core material is, for example, cardboard or resin board, and the flexible member is, for example, a lining material such as polyester. Since the handle portions 15 and 16 cannot be folded where the core material is located, folded portions Ta1, Tb1, Tc1, Ta2, Tb2, and Tc2 are formed where folding is required. The folded portions Ta1, Tb1, Tc1, Ta2, Tb2, and Tc2 are parts that lack a core material and are connected only by the flexible member.

[0043] As shown in Figure 7, the reinforcing component 5 is constructed by assembling two reinforcing plates 51 and 52. The reinforcing plates 51 and 52 are less prone to bending than the left sheet member 12, right sheet member 13, and bottom sheet member 14 of the bag body 2. The reinforcing plates 51 and 52 are formed from a core material and a flexible member (e.g., a lining material) that has flexibility and covers the front and back surfaces of the core material. The core material is, for example, cardboard, and the flexible member is, for example, a lining material such as polyester.

[0044] When the reinforcing plate 51 is placed inside the bag body 2, it has a bottom portion 51a facing the inner surface of the bottom sheet member 14, a left portion 51b facing the inner surface of the left sheet member 12, a right portion 51c facing the inner surface of the right sheet member 13, and a mounting surface reinforcing portion 51A facing the front sheet member 10. The left portion 51b, the right portion 51c, and the mounting surface reinforcing portion 51A extend upward from both ends of the short side and the end of the long side of the bottom portion 51a.

[0045] The left portion 51b and the right portion 51c are vertically elongated rectangles, while the mounting surface reinforcement portion 51A is horizontally elongated rectangle. The left portion 51b, the right portion 51c, and the mounting surface reinforcement portion 51A are each rotatable around the connection point with the bottom portion 51a.

[0046] A hook-and-loop fastener 51b1 is attached near the upper end of the inner surface of the left portion 51b, and a hook-and-loop fastener 51b2 is attached near the lower end. Similarly, a hook-and-loop fastener 51c1 is attached near the upper end of the inner surface of the right portion 51c, and a hook-and-loop fastener 51c2 is attached near the lower end.

[0047] The reinforcing plate 52 is a member (partition plate) that, when placed inside the bag body 2, divides the storage space between the front sheet member 10 and the back sheet member 11. The reinforcing plate 52 has a partition portion 52a, a left mounting portion 52b, and a right mounting portion 52c. The partition portion 52a has substantially the same shape as the front sheet member 10 and the back sheet member 11. The left mounting portion 52b and the right mounting portion 52c are rotatable with the left and right ends of the partition portion 52a as pivot points, but in Figures 7(a) and 7(b), the left mounting portion 52b and the right mounting portion 52c are shown extending from the left and right ends of the partition portion 52a toward the back.

[0048] A hook-and-loop fastener 52b1 is attached near the upper end of the outer surface of the left mounting portion 52b, and a hook-and-loop fastener 52b2 is attached near the lower end. Similarly, a hook-and-loop fastener 52c1 is attached near the upper end of the outer surface of the right mounting portion 52c, and a hook-and-loop fastener 52c2 is attached near the lower end.

[0049] Therefore, when two reinforcing plates 51 and 52 are assembled to form a reinforcing plate 5, as shown in Figures 7(a) and 7(b), the outer surface of the left mounting portion 52b of reinforcing plate 52 is placed opposite the inner surface of the left portion 51b of reinforcing plate 51, and the hook fasteners 51b1 and 52b1 near their upper ends are joined, and the hook fasteners 51b2 and 52b2 near their lower ends are joined. Similarly, the outer surface of the right mounting portion 52c of reinforcing plate 52 is placed opposite the inner surface of the right portion 51c of reinforcing plate 51, and the hook fasteners 51c1 and 52c1 near their upper ends are joined, and the hook fasteners 51c2 and 52c2 near their lower ends are joined. Furthermore, when the reinforcing plate 52 is integrated with the reinforcing plate 51, the reinforcing plate 52 restricts the reduction of the distance between the left portion 51b of the reinforcing plate 51, which is positioned along the left sheet member 12, and the right portion 51c of the reinforcing plate 51, which is positioned along the right sheet member 13.

[0050] Alternatively, the two reinforcing plates 51 and 52 may be assembled and integrated to form the reinforcing plate 5, and then inserted into the bag body 2; or, the reinforcing plate 51 may be inserted into the bag body 2, and then the reinforcing plate 52 may be integrated with the reinforcing plate 51 inside the bag body 2.

[0051] As shown in Figure 8, the reinforcing plate 5, configured as described above, is placed inside the bag body 2 of the bag 1 in a standing position, with the handle portions 15 and 16 positioned along the outer circumferential surfaces of the front sheet member 10 and the back sheet member 11, respectively. Then, the left portion 51b of the reinforcing plate 51 is positioned along the inner surface of the left sheet member 12, and the right portion 51c of the reinforcing plate 51 is positioned along the inner surface of the right sheet member 13. In addition, the mounting surface reinforcing portion 51A of the reinforcing plate 51 is positioned to face the inner surface of the front sheet member 10. In this state, when the bag 1 in a standing position is placed so that the handle portion 16 positioned along the outer circumferential surface of the back sheet member 11 is in contact with a support surface such as a desk, it can be used as a laptop stand, as shown in Figure 9.

[0052] In this embodiment, when the stand is positioned such that the handle portion 16, which is arranged along the outer circumferential surface of the back sheet member 11, is in contact with a support surface such as a desk, the front sheet member 10 and the back sheet member 11 are positioned substantially horizontally, and the handle portion 15, which is arranged along the outer circumferential surface of the front sheet member 10, forms a part of the PC mounting surface A.

[0053] In this embodiment, even when the bag 1 is used as a laptop stand, the opening 2a remains open. Therefore, documents and other items can be stored in or taken out of the storage space inside the bag 1 while using the laptop. In the bag 1, a reinforcing plate 52 is positioned inside the reinforcing plate 51 as a partition plate, so the storage space inside the bag 1 can be divided into two storage spaces. Therefore, even when the bag 1 is used as a laptop stand, it is not necessary to take out everything stored inside the bag 1. This prevents unnecessary documents and other items from being scattered on the desk.

[0054] When the stand-up bag 1 is used as a laptop stand, the back of the laptop is placed so as to contact the upper surface of the handle portion 15, which is positioned along the outer periphery of the front sheet member 10. At this time, the handle portion 15 is positioned approximately horizontally, and the area where the handle portion 15 is positioned along the outer periphery of the bag body 2 is the laptop mounting surface A on which the laptop is placed. The handle portion 15 is approximately the same size as the outer periphery of the bag body 2, and the area of ​​the laptop mounting surface A is greater than or equal to the area of ​​the back of the laptop placed on the laptop mounting surface A.

[0055] Thus, in the stand-up bag 1, the PC mounting surface A is constructed by laminating a front sheet member 10, a handle portion 15 positioned along the outer circumferential surface of the front sheet member 10, and a mounting surface reinforcement portion 51A of a reinforcing plate 51 positioned along the inner surface of the front sheet member 10, as shown in Figure 11. Therefore, on the PC mounting surface A, three core materials are laminated: the core material of the handle portion 15, the core material of the front sheet member 10, and the core material of the mounting surface reinforcement portion 51A of the reinforcing plate 51, resulting in increased rigidity of the PC mounting surface A.

[0056] Furthermore, when the bag 1 in its standing position has its handles 15 and 16 positioned along the outer circumferential surfaces of the front sheet member 10 and the back sheet member 11, and the opening 2a is opened, it can be used as a storage box with a relatively large storage capacity. It can also be used as a storage box by standing it upright on a desk, for example, with the opening 2a facing upwards. In this case, the handles 15 and 16 are positioned along the outer circumferential surfaces of the front sheet member 10 and the back sheet member 11, respectively, and as shown in Figure 12, it can be stored on a storage shelf like other file boxes 60 with documents and other items placed inside. In this embodiment, the bag 1 in its standing position has approximately the same size and thickness as a normal file box 60.

[0057] As described above, the bag 1 of this embodiment has a bag body 2 formed in a concave shape with an opening 2a, and a pair of handles 15 and 16 connected to the bag body 2 for use when carrying it. The pair of handles 15 and 16 are connected to the long edge side of the opening 2a, respectively, and the bag is configured to be able to assume a standing position where the pair of handles 15 and 16 are positioned along the outer circumferential surface of the bag body 2, respectively.

[0058] With this configuration, even when used as a laptop stand, the opening 2a of the bag 1 remains open, allowing access to the storage space within the bag 1. Furthermore, when used as a laptop stand, the handles 15 and 16 are positioned along the outer periphery of the bag body 2, preventing them from getting in the way when placing documents or other items in front of the laptop.

[0059] In the bag 1 of this embodiment, the handle portions 15 and 16 have substantially the same size as the outer circumferential surface of the bag body 2.

[0060] With this configuration, the computer can be placed on a flat surface without any steps or unevenness.

[0061] In the bag 1 of this embodiment, the handle portions 15 and 16 each have a joint portion 151 and 161 that is joined to the outer circumferential surface of the bag body 2 on the long edge side of the opening 2a, and a movable portion 152 and 162 that is bendable at the ends 151a and 161a of the joint portions 151 and 161 opposite to the opening 2a, and in which handle holes 15a and 16a are formed.

[0062] With this configuration, when carrying the bag 1 by gripping the handle holes 15a and 16a with your fingers, it is possible to prevent the distance between the handle holes 15a and 16a of the handle portions 15 and 16 and the upper end of the bag 1 from becoming too large.

[0063] In the bag 1 of this embodiment, the movable part 153 has a bent portion Ta1 that bends along the long edge of the opening 2a when it is bent at the end 151a of the joint 151 and faces the outer circumferential surface of the joint 151.

[0064] With this configuration, the movable part 153 of the handle part 15 can be bent at the bending part Ta1 and used as a lid member to cover the opening 2a.

[0065] In the bag 1 of this embodiment, the movable part 153 has a bent part Tb1 that is positioned on the opposite side of the end 151a of the joint part 151 relative to the bent part Ta1, and the handle hole 15a is positioned on the opposite side of the bent part Ta1 relative to the bent part Tb1.

[0066] With this configuration, if the bag 1 has a pair of handles 15 and 16, the bag 1 can be carried by gripping the handle holes 15a and 16a formed in the pair of handles 15 and 16 with the fingers, while the handle holes 15a and 16a are close together.

[0067] In the bag 1 of this embodiment, the bag body 2 has a front sheet member 10, a back sheet member 11 facing the front sheet member 10, and a left sheet member 12, a right sheet member 13, and a bottom sheet member 14 connecting the front sheet member 10 and the back sheet member 11. The front sheet member 10 and the back sheet member 11 are formed of a core material and a flexible member having flexibility that covers the front and back surfaces of the core material. The left sheet member 12, the right sheet member 13, and the bottom sheet member 14 are formed of a flexible member having flexibility. Inside the bag body 2, reinforcing plates 51 are arranged along the left sheet member 12, the right sheet member 13, and the bottom sheet member 14.

[0068] With this configuration, the shape of the bag 1 can be properly maintained in the standing position by aligning the reinforcing plate 51 with the flexible left sheet member 12, right sheet member 13, and bottom sheet member 14. Furthermore, the bag body 2 can be folded by bending the left sheet member 12, right sheet member 13, and bottom sheet member 14 so that the inner surface of the front sheet member 10 and the inner surface of the back sheet member 11 come closer together.

[0069] In the bag 1 of this embodiment, the handle portion 15 is formed of a core material and a flexible member having flexibility that covers the surface and back surface of the core material.

[0070] With this configuration, the rigidity of the PC mounting surface A is increased, which prevents the PC mounting surface A from bending and causing the PC to shake during use.

[0071] In the bag 1 of this embodiment, the reinforcing plate 51 has a mounting surface reinforcing portion 51A that is positioned along the front sheet member 10 when the bag is in a standing position.

[0072] With this configuration, the rigidity of the PC mounting surface A is increased, which prevents the PC mounting surface from bending and causing the PC to shake during use.

[0073] In this embodiment, bag 1 has a reinforcing plate 52 positioned inside the reinforcing plate 51.

[0074] With this configuration, the storage space inside bag 1 can be divided into multiple storage compartments when the bag is in a standing position.

[0075] In the bag 1 of this embodiment, the reinforcing plate 52 restricts the distance between the left portion 51b of the reinforcing plate 51, which is positioned along the left sheet member 12, and the right portion 51c of the reinforcing plate 51, which is positioned along the right sheet member 13, from becoming smaller.

[0076] With this configuration, the shape of bag 1 can be maintained more appropriately.

[0077] Although embodiments of the present invention have been described above, the configuration of this embodiment is not limited to those described above, and various modifications are possible.

[0078] For example, in the above embodiment, the bag 1 in the standing position is substantially rectangular in shape, but it is not limited to that. The shape of the bag 1 in the standing position is arbitrary.

[0079] In the above embodiment, the bag 1 has a reinforcing component 5, but it is not limited to that. Even when the bag 1 has a reinforcing component 5, the shapes of the reinforcing plates 51 and 52 may be different from those in the above embodiment. Also, the reinforcing component 5 does not have to include the reinforcing plate 52.

[0080] In the above embodiment, when the bag 1 in a standing position is used as a laptop stand, the laptop mounting surface A is substantially horizontal, but it is not limited to this. When the bag 1 of the present invention is used as a laptop stand, the laptop mounting surface A may be inclined.

[0081] In the above embodiment, the handle portions 15 and 16 have connecting portions 151 and 161 that are joined to the outer circumferential surface of the bag body 2, but the invention is not limited to this. In the bag 101 of the present invention, the handle portions 115 and 116 may be configured to be rotatable at the upper end of the bag body 2, as shown in Figure 13. In that case, the connecting portions 151 and 161 are also movable parts, similar to the movable portions 152 and 162.

[0082] In the above embodiment, the bag 1 of the present invention, as described above, can be stored on a storage shelf in the same way as other file boxes 60, etc., as a storage box with documents and the like placed inside. It has a bag body 2 formed in a concave shape with an opening 2a, and a pair of handles 15 and 16 connected to the bag body 2 for carrying. The pair of handles 15 and 16 are connected to the long edge side of the opening 2a, respectively, and the bag is also configured to be a storage box that can assume a standing position with the pair of handles 15 and 16 positioned along the outer circumferential surface of the bag body 2, respectively.

[0083] In the above embodiment, the front sheet member 10, the back sheet member 11, and the handle portions 15 and 16 are formed from a core material and flexible members that cover the front and back surfaces of the core material, but the materials of the core material and the flexible members are arbitrary.

[0084] Other configurations can also be modified in various ways without departing from the spirit of the present invention. [Explanation of Symbols]
