By forming the main body of the bag of the present invention from paper or non-woven fabric, the weight of the bag can be reduced as compared with cloth or leather. In particular, a heavy bag made of kraft paper has sufficient strength, and various designs can be given at low cost by printing, so that bags with different designs can be produced in small quantities and in a wide variety of types.

The figure which shows one Embodiment of the bag of this invention. The figure which made the bag which is one Embodiment a small capacity handbag. The figure which made the bag which is one Embodiment a shoulder bag.

FIG. 1 shows a bag according to an embodiment of the present invention. In one embodiment shown in FIG. 1, the figure represents the first surface side, and the second surface side, which does not appear in the figure, has the same configuration as the first surface.
The bag 100 according to the embodiment shown in FIG. 1 includes a bag-shaped and square main body 10 having an opening 11 at the upper side, and a first string 20a provided on the first surface 10a of the main body 10. , The second string 20b provided on the second surface 10b (not shown) of the main body and the first string 20a provided above the first surface of the main body move up and down between the main body 10. A second reinforcing member 30b provided above the second surface of the main body and sandwiching the second string 20b between the main body 10 so as to be movable up and down between the first reinforcing member 30a to be sandwiched as possible. (Not shown) and. Hereinafter, the first string 20a and the second string 20b may be collectively referred to as a "string 20", and the first reinforcing member 30a and the second reinforcing member 30b may be collectively referred to as a "reinforcing member 30".

The main body 10 stores an article inside. A magnet, a fastener, or the like is provided in the opening 11 above the main body so that it can be opened and closed. In the bag 100 according to one embodiment, the main body 10 is formed of a heavy bag made of kraft paper.
A heavy bag is made by folding one or a plurality of stacked sheets of kraft paper into a tubular shape, covering one end with reinforcing tape and sewing, and storing heavy objects such as cement and rice. Widely used to do this. Further, in the heavy bag, a polymer film such as polyethylene may be laminated in order to impart moisture resistance depending on the contents. When a heavy bag is used as the main body 10, a heavy bag on which polymer films are laminated can also be used. A heavy bag provided with a polymer film is less likely to tear and has excellent waterproof properties as compared with a heavy bag made only of kraft paper.

The heavy bag can be given various designs by printing. As described in detail below, the bag of the present invention is used in different forms by printing different designs on the first side 10a and the second side 10b, either the top and bottom of each side, or both. In some cases, the appearance can be greatly changed, and the bag can have a different design depending on the clothes, mood, and the like. Further, the main body 10 is formed from a heavy bag, and one or more of the first string 20a, the second string 20b, the first reinforcing member 30a, and the second reinforcing member 30b are formed from cloth, leather, or the like. It is possible to express various textures due to the difference in materials and to give excellent design.

In the bag of the present invention, the material forming the main body 10 is not limited to kraft paper, and paper other than kraft paper, non-woven fabric, cloth, natural leather, artificial leather and the like can be used. Among these, paper or non-woven fabric can be preferably used because it is lightweight and easy to fold.

When the main body 10 is formed from paper, paper made of pulp into a sheet can be used without particular limitation, but wood pulp is the main component because it has practical strength when made into a bag. It is preferable to use paper. Wood pulp includes chemical pulp (bleached or unbleached kraft pulp of coniferous tree, bleached or unbleached kraft pulp of broadleaf tree, etc.), mechanical pulp (ground pulp, thermomechanical pulp, chemical thermomechanical pulp, etc.), deinked pulp, etc. Pulp can be used alone or in any proportion. Among these, softwood kraft pulp (NKP) is preferably contained in an amount of 50% by weight or more, more preferably 60% by weight or more, and further preferably 80% by weight or more. By setting the softwood kraft pulp to 50% by weight or more, the strength of the base paper can be increased and the durability can be improved. Further, from the viewpoint of strength, the raw material pulp is preferably unbleached, and particularly preferably softwood unbleached kraft pulp (NUKP) is used.

The string 20 serves as a handle when the bag 100 is used as a handbag. Further, as will be described in detail below, the string 20 serves as a shoulder strap when the bag 100 is used as a shoulder bag. It is preferable that the string 20 has a band shape because the pressure is dispersed and the usability is excellent.
Both ends of the first string 20a and the second string 20b are sewn so as to sandwich the lower locking tool 40 at the bottom of the main body 10, and are sewn to the main body 10 at other parts. It is not fixed by adhesion or the like. Further, the first string 20a and the second string 20b are the first upper locking tool 41a and the second upper hook, respectively, which lock with the lower locking tool 40 when the main body 10 is bent up and down. A stopper 41b (not shown) is provided. Hereinafter, the first upper locking tool 41a and the second upper locking tool 41b may be collectively referred to as an "upper locking tool 41". Here, when the bag of the present invention is folded and used, the bottom portion of the main body 10 is located below the reinforcing member 30. Therefore, the upper locking portion 41 is provided at a position immediately below the reinforcing member 30 when the bag of the present invention is used as a large-capacity bag, that is, when it is used without folding. Further, the upper locking tool 41 can be provided only on one of the first string 20a and the second string 20b.

The lower locking tool 40 and the upper locking tool 41 are paired and locked to each other. The lower locking tool 40 and the upper locking tool 41 are not particularly limited as long as they can be locked to each other, and buckles, eggplant cans, hooks, rings, hooks, magnets and the like can be appropriately used.

The reinforcing member 30 reinforces the opening 11. The reinforcing member 30 is sewn to the main body 10 so as to sandwich the string 20 with the main body 10. As described above, the string 20 is sewn to the bottom of the main body 10, but since the other parts are not fixed to the main body 10, it can be moved up and down while being sandwiched between the reinforcing members 30. .. The string 20 can move up and down, but the movement in the lateral direction is restricted by the reinforcing member 30. In the bag of the present invention, since the movement of the string 20 in the lateral direction is restricted, even when a heavy object is stored in the bag, the distance between the handles is not narrowed and the bag can be held in a stable state. it can.

As described above, in the bag of the present invention, the string 20 is sewn only to the bottom of the main body 10. Therefore, in the bag of the present invention, the weight of the article contained in the bag is supported by the string 20, and almost no tension is applied to the main body 10. In the bag of the present invention, even when the main body 10 is made of paper, almost no tension is applied to the main body 10 made of paper, so that the bag is not easily torn even if a protrusion or the like comes into contact with it during use.

"Usage mode"
The bag of the present invention can be changed into a large-capacity handbag, a small-capacity handbag or pouch, or a shoulder bag depending on the application. The size of the bag of the present invention is not particularly limited, but it is preferable that the bag has a size that can store bulky products such as disposable diapers, tissue paper, and toilet paper when a large-capacity handbag is used. For example, the width direction of the main body 10 is 35 cm or more and 50 cm or less, the length of the main body 10 in the stretched state is 50 cm or more and 70 cm or less, and the length of the main body 10 in the folded state is 30 cm or more and 40 cm or less. ..

Hereinafter, each usage mode of the bag 100, which is one embodiment, will be described with reference to FIGS. 2 and 3.
The bag 100, which is one embodiment, can be used as a large-capacity handbag in a stretched state without being folded (FIG. 1).
When the bag 100 according to one embodiment is used as a small-capacity handbag with the second surface 10b on the outside, the main body 10 is folded in the vertical direction with the first surface 10a on the inside, and the lower locking tool 40 is used. The upper locking tool 41a is locked to each other (FIG. 2). Since the upper locking tool 41a of the first string 20a is locked with the lower locking tool 40, the first string 20a moves even if the bag 100 is lifted by holding only the first string 20a. The bag 100 can be lifted without any need.
From this state, the lower locking tool 40 and the upper locking tool 41a are unlocked, and the first string 20a is pulled upward from the first reinforcing member 30a to form a shoulder bag (FIG. 3). .. In FIG. 3, the first string 20a is passed through the handle portion of the second string 20b to prevent the opening 11 from opening wide during use, but the opening 11 is closed by a magnet, a fastener, or the like. You can also do it.

When the bag of the present invention is used as a small-capacity handbag or a shoulder bag, either the first surface 10a or the second surface 10b of the main body 10 is on the outside. Further, the outer surface is divided into upper and lower surfaces and is located on both side surfaces. Since the outer side of the bag of the present invention is different when used as a large-capacity handbag and when used as a small-capacity handbag or a shoulder bag, the first surface 10a and the second surface By printing different designs on 10b, either the upper part or the lower part of each side, or both, the appearance and impression change greatly with the form, and it can be used as a bag with different fashionability according to the mood and clothes of the day. Can be done.
