Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.
FIG. 1 shows the configuration of an embodiment of a bag according to the present invention.
In FIG. 1, the bag 10 is flat and has a bag-shaped main body 11 having an open upper edge extending in the longitudinal direction (left-right direction in the drawing) and a tubular main body 11 provided along the upper edge of the main body 11 having both ends open. It is composed of a single annular string 12 inserted through the string threading portion 11a.

The main body 11 is made of a flexible sheet-like synthetic resin material such as polyester, and connects the two flat portions 11a and 11b on the front and back and the left and right ends of these two flat portions 11a and 11b. It is provided with gusset portions 11c and 11d provided as described above.
The material constituting the main body 11 may be a cloth material such as a cotton material or a non-woven fabric in addition to a synthetic resin material such as polyester.

The lower ends of the flat portions 11a and 11b of the main body 11 are connected to each other or integrally configured by an appropriate method such as sewing, welding, or adhesion.
On the other hand, the flat portions 11a and 11b of the main body 11 are connected to each other via the left and right gusset portions 11c and 11d.

As shown in the enlarged cross-sectional view of FIG. 2, the gusset portions 11c and 11d are arranged at both ends of the flat portions 11a and 11b of the main body 11 so as to be folded back between them.
In the figure, the flat portions 11a and 11b of the main body 11 are formed in an inverted trapezoidal shape with the left and right edges inclined inward in the longitudinal direction toward the bottom, and the gusset portions 11c and 11d are formed in the flat portion 11a. , 11d are integrally formed by bending both edges inward, and the bent tips are connected to each other.

Preferably, the flat portions 11a and 11b and the gusset portions 11c and 11d of the main body 11 are formed by cutting a tubular film sheet and crushing the tubular film sheet flatly, folding the left and right ends inward to form a gusset portion, and forming a gusset portion at the lower end. By closing by sewing, welding, adhesion, etc., the main body 11 can be easily configured with a small number of steps.

Further, in the main body 11, the upper edges of the flat portions 11a and 11b are folded back inward or outward, respectively, and the lower ends thereof are connected to the flat portions 11a and 11b by sewing, welding, adhesion or the like. It is provided with a tubular string threading portion 11e.
The stringing portion 11e is open at both left and right ends of the upper edges of the flat portions 11a and 11b of the main body 11, respectively.

Further, the main body 11 is provided with a notch portion 11f having a concave shape downward in the vicinity of the center in the longitudinal direction of the upper edges of the flat portions 11a and 11b.
In the region of the notch portion 11f, the stringing portion 11e does not exist.
Further, a pocket 11h is attached to the inside of either the flat portion 11a or the flat portion 11b near the lower portion of the notch portion 11f by an appropriate method such as sewing, welding, or adhesion. The pocket 11h can be used for storing articles, and the flat portions 11a and 11b can be made into a portable shape by folding the back 10 described later and inserting the flat portions 11a and 11b into the pocket 11h.

The annular string 12 is made of a flexible and rigid material such as a rope made of synthetic fibers such as nylon, polypropylene, polyethylene and polyester, and a rope made of natural fibers such as cotton and linen. As shown, it is inserted into the stringing portion 11e of the main body 11 in a state of being annular and extending straight in the longitudinal direction.
The annular string 12 is manufactured in a state of being cut at one place, is inserted into the string threading portion 11e of the main body 11, and then the cut portion is joined with a tape or the like to form a joint portion 12c. ..
The joined portion 12c may be formed by connecting the cut portions without joining them.

Here, the annular string 12 is deformable in terms of flexibility so as to correspond to various usage modes described below.
On the other hand, regarding the rigidity of the annular string 12, as shown in FIG. 1, the main body 11 is horizontally expanded and the annular string 12 is extended in the longitudinal direction in the string threading portion 11e of the main body 11. When the exposed portion in the notch portion 11f of the annular string 12 is gripped as a handle, the upper edge of the main body 11 can be supported substantially horizontally over the entire longitudinal direction, that is, the longitudinal direction of the upper edge of the main body 11. It has enough rigidity that the vicinity of both ends does not hang down too much.
Therefore, as the annular string 12, for example, the above-mentioned synthetic fiber or natural fiber having a thickness of about 4 to 20 mm can be used so as to have such flexibility and rigidity.

The bag according to the embodiment of the present invention is configured as described above, and is used in various usage modes as shown below.
That is, first, as shown in FIG. 1, the bag 10 is in a state where the main body 11 is spread flat and the annular string 12 is inserted into the string threading portion 11e provided on the upper edge of the main body and extends in the longitudinal direction. , The exposed portion in the notch portion 11f of the annular string 12 is gripped as a handle.

As a result, the upper edge of the main body 11 is supported substantially horizontally over the entire longitudinal direction based on the rigidity of the annular string 12, so that the upper edge of the main body 11 is flattened without being narrowed down in the longitudinal direction. It is held in a so-called tote bag-like shape.
Therefore, for example, a flat document or the like housed inside the main body 11 does not bend, and can be stably housed in a flat state.

Here, when the bag 10 is not used, as shown in FIG. 4, the main body 11 and the annular string 12 can be folded together in a small size.
First, the gusset portion 11d is folded with respect to the main body 11 (FIG. 4 (a)), and then the gusset portion 11c is also folded with respect to the main body 11 (FIG. 4 (b)). Then, by folding the main body 11 a plurality of times from the lower part to the upper part, the size becomes compact, and an elastic belt 11 g such as an annular rubber belt fixed near the notch portion 11f is pulled out and turned around the folded main body 11. Thereby, based on the elasticity of the elastic belt 11 g, the main body 10 can be held in a folded state and carried (FIG. 4 (c)).
Further, although not shown, as described above, from the folded state of the main body 10 as shown in FIG. 4B, the pocket 11h attached to the flat portion 11a or the flat portion 11b is taken out to the outside of the main body 10 and folded. By storing the main body 10 in the pocket 11h, it can be formed into a portable shape.
Therefore, a separate storage bag for accommodating the bag 10 when not in use becomes unnecessary, and the bag 10 can be used more easily.

FIG. 5 shows a second use mode of the bag 10 according to the embodiment of the present invention.
In FIG. 5, in the bag 10, the upper edges of the flat portions 11a and 11b of the main body 11 and the string threading portion 11e are narrowed down from the central notch portion 11f to the vicinity of both ends in the longitudinal direction, and the central portion of the annular string 12 is formed. It is pulled out upward from the notch portion 11f.
Thereby, the bag 10 can be used like a shoulder bag by hanging the central portion of the annular string 12 on the shoulder.

FIG. 6 shows a third use mode of the bag 10 according to the embodiment of the present invention.
In FIG. 6, in the bag 10, the upper edges and stringing portions 11e of the flat portions 11a and 11b of the main body 11 are narrowed down from both ends in the longitudinal direction to the vicinity of the central notch portion 11f, and the annular string 12 is the stringing portion. It is largely pulled upward from both ends in the longitudinal direction of 11e.
As a result, the bag 10 can be used like a drawstring bag by gripping both end portions of the annular string 12 together.
In this case, as shown by the chain line in FIG. 6, one end portion 12a of both end portions of the annular string 12 is passed through the inside of the other end portion 12b and pulled upward, and the one end portion 12a is pulled out upward. It is also possible to grasp the looped part of the sword or hang it on the shoulder.

FIG. 7 shows a fourth use mode of the bag 10 according to the embodiment of the present invention.
In FIG. 7, in the bag 10, the upper edges of the flat portions 11a and 11b of the main body 11 and the stringing portion 11e are narrowed down to one side in the longitudinal direction (on the right side in the drawing), and the annular string 12 has the stringing. The portion 11e is largely pulled upward from the other side in the longitudinal direction.
Thereby, the bag 10 can be used like a shoulder bag by hanging the looped portion on the other side of the annular string 12 on the shoulder or hanging it on the shoulder.

FIG. 8 shows a fifth use mode of the bag 10 according to the embodiment of the present invention.
In FIG. 8, in the bag 10, the upper edges of the flat portions 11a and 11b of the main body 11 and the string threading portions 11e are narrowed down from both ends in the longitudinal direction to the vicinity of the central notch portion 11e, and the annular string 12 is flat on one side. It is largely pulled upward from the notch 11e of the portion 11a or 11b.
Thereby, the bag 10 can be used like a shoulder bag by hanging the pulled-out portion of the annular string 12 on the shoulder or hanging it on the shoulder.

FIG. 9 shows a sixth use mode of the bag 10 according to the embodiment of the present invention.
In FIG. 9, the bag 10 has the main body 11 expanded flat and the annular string 12 inserted into the string threading portion 11e provided on the upper edge of the main body and has a length, as in the first usage mode in FIG. In the state of extending in the direction, both end portions 12a and 12b of the annular string 12 are exposed from the openings at both ends in the longitudinal direction of the string threading portion 11e, respectively.
Then, both ends 13a and 13b of the belt 13 are attached to the looped portions of the both end portions 12a and 12b of the annular string 12, respectively.

The belt 13 is a belt made of a synthetic fiber such as nylon and having a predetermined length or an adjustable length, and can be engaged with both ends 13a and 13b and a portion looped with both ends 12a and 12b of the annular string 12. It is equipped with various connectors 13c and 13d.
Here, hooks, buckles, and the like having known configurations can be used for the connecting portions 13c and 13d.

As a result, the upper edge of the main body 11 is supported substantially horizontally over the entire longitudinal direction based on the rigidity of the annular string 12, so that the upper edge of the main body 11 is flattened without being narrowed down in the longitudinal direction. It is held in a so-called tote bag-like shape. Further, to the main body 11 in such a flat state, the connecting tools 13c and 13d of the belt 13 are connected to both ends 12 and 12b of the annular string 12, respectively, and the belt 13 is hung on the shoulder as a shoulder belt.
Therefore, the bag 10 can be used as a shoulder bag while maintaining a flat shape.
In this case, if the length of the elastic belt 13 can be adjusted, it is possible to hang it at the optimum length for the user by appropriately adjusting the length.

The present invention can be implemented in various forms without departing from the spirit of the present invention.
For example, in the above-described embodiment, the flat portions 11a and 11b and the gusset portions 11c and 11d of the main body 11 are made of, for example, a sheet-shaped synthetic resin material and are formed by adhesion, welding or the like, but the present invention is limited to this.
