Description

[Technical field]

[0001] This invention relates to a portable bag which is made by overlapping and connecting two opposing pieces of fabric by sewing or the like, and which can be transformed from a two-dimensional folded portable bag into a three-dimensional bag for quick use. [Background technology]

[0002] Japan has a long history of wrapping things in cloth, and in recent years furoshiki have been reconsidered as a means of transporting things, such as bags. Because furoshiki can be freely transformed, it is possible to wrap items of various shapes and sizes by tying the corners of the furoshiki together, and at the same time, the knots for transporting things can easily be formed into handles, which is a basic feature of a bag.

[0003] In addition to these basic features, there are other ideas, such as furoshiki bag aids that are rigid and attached to the opening of the bag to make it easier to take things in and out and to prevent things from falling out, and furoshiki bags with handles that can be used as handbags or shoulder bags. These bags utilize furoshiki and can be folded compactly as a single piece of cloth when not in use and carried around. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6218082 [Patent Document 2] Patent Publication No. 2022-110136 [Patent Document 3] Patent Publication No. 2023-59192 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in all of Patent Documents 1 to 3, a separate handle member or the like must be attached or the shape of the opening for inserting and removing stored items must be adjusted when using the container, making the container difficult to handle.

[0006] In order to solve the above problems, the object of this invention is to quickly provide a portable bag with a three-dimensional structure without requiring a separate handle or auxiliary tool. [Means for solving the problem]

[0007] This device is characterized in that it comprises a first fabric and a second fabric arranged opposite each other, a pair of openings provided in the first fabric, and a bridge portion formed between the pair of openings, the first fabric and the second fabric being connected to each other at their respective outer peripheries. With this portable bag, simply by lifting the bridge portion, the bag body's own weight quickly changes the fabric from a flat structure to a three-dimensional structure, and the bridge portion and the opening serve as a handle and an opening for inserting and removing stored items, respectively, making it easy to handle.

[0008] The pair of openings is characterized in that they are formed symmetrically with respect to an axis. When the portable bag is in use, it is possible to easily take items in and out of the opening in a well-balanced manner.

[0009] The axis of symmetry of the opening does not coincide with the center of gravity of the first fabric. The entire bag is asymmetrical, making it possible to provide a highly designed portable bag.

[0010] The bridge portion can be raised to change the configuration from a two-dimensional one to a three-dimensional one. Before the bridge portion is lifted, the first and second fabrics are layered flatly, and the bag as a whole has a flat configuration, but by lifting the bridge portion, the first and second fabrics form a bag-like storage area, which can be changed to a three-dimensional configuration. Here, a flat configuration does not mean a completely two-dimensional plane, but includes a configuration close to a plane formed by layering two pieces of fabric. A three-dimensional configuration means that a three-dimensional shape is formed by forming a gap between the two layers of fabric. Effect of the Invention

[0011] The portable bag of this invention has the advantage that it can be freely transformed like a furoshiki to store items of various shapes and sizes, while like a Western-style bag it can be made from a variety of fabrics and has a wide range of designs and decorative features, making it a portable bag that combines the features of both. In addition, the bag is made of two flat pieces of fabric layered and connected by sewing or other methods, but by simply lifting the handle it can be transformed into a three-dimensional portable bag, and items can be quickly taken in and out of the opening, so it can be used without the hassle of conventional furoshiki bags. [Brief description of the drawings]

[0013] 1 to 3, the portable bag 1 comprises a first fabric 10 and a second fabric 20 arranged opposite to each other, and a pair of openings 30, 30 provided in the first fabric. The second fabric 20 has no opening. In this embodiment, the first fabric 10 and the second fabric 20 have the same shape and size, more specifically, are circular. The first fabric 10 and the second fabric 20 are layered, and an outer periphery 11 of the first fabric 10 and an outer periphery 21 of the second fabric 20 are connected to each other. In this embodiment, they are connected by sewing, but they may also be connected by adhesive or the like.

[0014] The openings 30, 30 are formed symmetrically with respect to the axis of symmetry L. The openings 30, 30 have an inner portion 31 located on the side of the axis of symmetry L and an outer portion 32 located on the opposite side, and the inner portion 31 and the outer portion 32 form an annular opening. The inner portion 31 is substantially linear, and the outer portion 32 is a curved portion that bulges outward. A bridge portion 33 that serves as a handle is formed between the inner portion 31 of one opening 30 and the inner portion 31 of the other opening 30.

[0015] The axis of symmetry L may be arranged so as not to coincide with the center of gravity G of the first fabric 10 and the second fabric 20. In this embodiment, the axis of symmetry L may be arranged so as not to coincide with the center of the first fabric 10 and the second fabric 20. By making the axis of symmetry L not coincide with the center of gravity G in this manner, the design of the bag when in use can be improved. That is, when the bridge portion 33 is lifted to form a bag shape, a part of the outer periphery 11 and the outer periphery 21 of the first fabric 10 and the second fabric 20 is located upward and an opposing part is located downward, and an asymmetrical design is applied to the entire bag.

[0016] The portable bag 1 as described above is easily foldable when not in use because it is made up of only two layers of fabric, the first fabric 10 and the second fabric 20, overlapping each other, and can be carried around compactly by folding. When in use, items can be put in through the openings 30, 30, and the bag can be used quickly without any troublesome work. It is desirable that such openings 30, 30 are sized to allow easy insertion and removal of items. The bridge portion 33 can be used as a handle by lifting it. Therefore, it is desirable that the vertical dimension of the bridge portion 33 is shaped and sized to allow easy holding in the hand or hanging on the shoulder.

[0017] The first fabric 10 and the second fabric 20 may be made of a relatively strong fabric such as denim, nylon, or canvas, or may be made of a relatively thin fabric. Natural leather or synthetic leather may also be used. The first fabric 10 and the second fabric 20 do not have to be made of the same fabric, and different fabrics may be used for the first fabric 10 and the second fabric 20, or each may be made of a different fabric in part. In particular, by using a stronger fabric for the bridge portion 33 than for the other portions, durability can be improved and a portable bag 1 with a high design quality can be provided.

[0018] The first fabric 10 and the second fabric 20 can be fully lined by using a separate lining fabric. In this embodiment, the first fabric 10 and the second fabric 20 are circular, but this is not limited thereto, and they may be elliptical or polygonal, for example. Furthermore, the first fabric 10 and the second fabric 20 are the same shape and size, but this is not limited thereto. As long as they are connected by the outer periphery 11 and the outer periphery 21, they may be different in size or shape.

[0019] The openings 30, 30 are provided line-symmetrically, but they do not need to be completely line-symmetrical, and may differ in size and shape to the extent that a bridge portion 33 formed by these openings 30, 30 can be handled.

[0020] This portable bag 1 can also have a separate pocket between the first fabric 10 and the second fabric 20. A zipper can be attached to the opening of the pocket. Also, to prevent stored items from falling out of the openings 30, 30 when the bridge part 33 is lifted, snap buttons or the like can be attached to the inside near the outer parts 32, 32 of the openings 30, 30, making it possible to connect these outer parts 32, 32 to each other.

[0021] The above-mentioned portable bag has the advantage that it can be freely transformed like a furoshiki to store items of various shapes and sizes, while at the same time, like a Western-style bag, it can be made from a variety of fabrics and has a wide range of designs and decorative features, thus providing a portable bag that combines the features of both. In addition, the bag is made of two flat pieces of fabric layered and connected by sewing or the like, but by simply lifting the handle, it can be transformed into a three-dimensional portable bag, and the opening can be used to quickly take items in and out, so it can be used without the troublesome work of conventional furoshiki bags.
