Description

本発明は、不織布からなる袋、例えば、買物袋、小物袋又は手提げ袋等の日常的に使用され得る袋に関する。 The present invention relates to a bag that can be used on a daily basis, such as a bag made of non-woven fabric, such as a shopping bag, a small bag or a handbag.

従来、不織布からなる袋は軽量で持ち運ぶのに便利であるが、繰り返して使用すると、次第に袋口の周縁が徐々に擦り切れたり、又はほころびたりし、さらに使用を続けると、袋口の周縁から袋本体へと裂け目が生じ、袋としての機能を損なうことがあった。また、袋の取手又は手提げ紐は通常、袋口の周縁に形成又は取着されており、袋内に物品を収納して持ち運ぶとき、袋口の周縁のうち袋の取手の形成部分又は手提げ紐の取着部分には該物品の荷重が特に加わる。そのため、その部分から切れ目が入ったり又は破れたりし、さらに使用を続けるとこれら切れ目又は破れがさらに周辺に広がり、そのため袋として使用できなくなるという問題があった。
そこで従来、これらの不具合を解消するために、袋口の周縁の強度を上げた袋が提案されている。かような袋として例えば、図７ないし図９に示すように、袋口の周縁を１回以上折り返して２重又は３重構造となるように作ることによって、該周縁が補強された袋が挙げられる。図７に示す袋１９は、袋口２０の周縁２１を内側に１回折り返したことにより、袋本体２２の厚さよりも２倍厚い補強部２３を形成した構造のものである（図７中のＣ部分の断面図である図８をも参照。）。また、袋１９には通常、装飾のためにエンボス模様２４、或いは絵模様２５が施される（図７中のＣ部分の拡大図である図９をも参照。）。また、このように袋口の周縁を折り返すことにより該周縁の強度を上げた技術が具体的に採用された袋としては、例えば特許文献１に記載のポリエステル不織布手提げ袋が挙げられる。特許文献１によると、ポリエステル不織布手提げ袋は、提げ手６を袋体３の口部５の側縁部７に超音波融着して接合してなり、そして側縁部７は、内側に折り返して２層構造としたことにより、提げ手６を接合する口部５の補強が図られている。
また、袋口の周縁の強度を上げた他のタイプの袋としては例えば、図１０ないし図１２に示すように、袋口の周縁を折り返して該折り返し部分と袋本体との間の中空部分に厚紙又はプラスチック製のシートなどの補強部材を入れた袋が挙げられる。図１０に示す袋２６は、袋口２７の周縁２８が内側に１回折り返され、さらに、折り返した部分と袋本体２９との間の中空部分に補強部材として厚紙３０を入れたことにより、補強部３１を形成した構造のものである（図１０中のＤ部分の断面図である図１１をも参照。）。そして、袋２６には通常、装飾のためエンボス模様３２、或いは絵模様３３が施されている（図１０中のＤ部分の拡大図である図１２参照。）。
特開２００１−１９０３１７号公報 Conventionally, a bag made of nonwoven fabric is lightweight and convenient to carry, but if it is used repeatedly, the periphery of the bag mouth will gradually be worn out or frayed gradually. A tear may occur in the main body, which may impair the function of the bag. In addition, the bag handle or hand strap is usually formed or attached to the periphery of the bag mouth, and when the article is stored and carried in the bag, the bag handle forming portion or hand strap in the periphery of the bag mouth. In particular, the load of the article is applied to the attachment portion. For this reason, there is a problem in that a break enters or breaks from the portion, and if the use is further continued, the break or tear further spreads to the periphery, and therefore cannot be used as a bag.
Therefore, conventionally, in order to solve these problems, a bag with increased strength at the periphery of the bag mouth has been proposed. For example, as shown in FIGS. 7 to 9, such a bag includes a bag whose peripheral edge is reinforced by folding the peripheral edge of the bag mouth one or more times to form a double or triple structure. It is done. The bag 19 shown in FIG. 7 has a structure in which a reinforcing portion 23 that is twice as thick as the thickness of the bag main body 22 is formed by turning the peripheral edge 21 of the bag mouth 20 once inward (see FIG. 7). (See also FIG. 8, which is a cross-sectional view of portion C). Moreover, the embossed pattern 24 or the pictorial pattern 25 is normally given to the bag 19 for decoration (refer also FIG. 9 which is an enlarged view of the C section in FIG. 7). In addition, as a bag in which a technique that specifically increases the strength of the peripheral edge by folding the peripheral edge of the bag mouth as described above, for example, a polyester nonwoven fabric handbag described in Patent Document 1 can be cited. According to Patent Document 1, the polyester non-woven handbag is formed by ultrasonically welding the hand 6 to the side edge 7 of the mouth portion 5 of the bag body 3, and the side edge 7 is folded inward. By adopting a two-layer structure, the mouth portion 5 for joining the handle 6 is reinforced.
Further, as another type of bag with increased strength at the periphery of the bag mouth, for example, as shown in FIGS. 10 to 12, the periphery of the bag mouth is folded back into a hollow portion between the folded portion and the bag body. A bag containing a reinforcing member such as a cardboard sheet or a plastic sheet may be used. The bag 26 shown in FIG. 10 is reinforced by the peripheral edge 28 of the bag mouth 27 being folded once inside, and the cardboard 30 being inserted as a reinforcing member in the hollow portion between the folded portion and the bag body 29. The portion 31 is formed (see also FIG. 11 which is a cross-sectional view of a portion D in FIG. 10). And the embossed pattern 32 or the picture pattern 33 is normally given to the bag 26 for the decoration (refer FIG. 12 which is the enlarged view of the D section in FIG. 10).
JP 2001-190317 A

しかしながら、従来の袋においては、不織布の袋地は薄いため、袋口の周縁の内側に折り返された部分のエンボス模様又は絵模様が袋の外面から透けて見えるので（例えば、図８及び図９に記載の従来の袋１９のエンボス模様２４’、並びに、図１１及び図１２に記載の従来の袋２６のエンボス模様３２’）、これらエンボス模様又は絵模様が外面のエンボス模様又は絵模様と重なって写し出され、そのため不自然な模様に見えてしまうという不都合があった。また、従来の袋の補強部は、袋口の周縁を折り返すことにより厚みを増すものであるので、厚さが整数倍のものに限られる。例えば、補強部に対して袋本体の厚さの１．２倍の厚さに相当する程度の強度が必要十分とされる場合であっても、周縁を１回折り返して袋本体の厚さの２倍の厚さに調整するしかないという不都合があった。さらに、従来の袋においては、袋口の周縁を折り返すという作業が必要であるため、手間が
かかり、生産効率が低い。特に、抜手袋の場合においては、袋口の周縁を折り返すという作業を手作業で行わなければならず、生産性の面で問題であった。さらにその上、厚紙のような補強部材が用いられた袋においては、補強部材の材料費がかさむ上に、厚紙を入れる作業が煩わしいという不都合もあった。
本発明は、このような事情を考慮し為されたものであって、袋口の周縁の強度が高いだけでなく、その強度向上を自在に調節でき、且つ、袋の外面に施されたエンボス模様又は絵模様が折り返し部分の透け見えるこれら模様と重なって不自然に見えるという不具合が起きず、さらに、袋口の周縁を折り返す作業を必要とせず、及び、袋口の周縁の強度を上げるための補強部材を別途用いる必要のない袋の提供を課題とする。 However, in the conventional bag, since the nonwoven fabric bag is thin, the embossed pattern or the picture pattern of the folded portion inside the periphery of the bag mouth can be seen through from the outer surface of the bag (for example, FIG. 8 and FIG. 9). 11 and the embossed pattern 32 ′ of the conventional bag 26 shown in FIGS. 11 and 12, and the embossed pattern or the picture pattern overlaps with the embossed pattern or the picture pattern on the outer surface. There was an inconvenience that it was projected, and thus it looked unnatural. Moreover, since the reinforcement part of the conventional bag increases thickness by folding the periphery of a bag mouth, it is limited to a thing with an integral multiple of thickness. For example, even if the strength corresponding to 1.2 times the thickness of the bag body is necessary and sufficient with respect to the reinforcing portion, the periphery of the bag body is There was an inconvenience that there was no choice but to adjust the thickness twice. Furthermore, in the conventional bag, since the operation | work of turning up the periphery of a bag mouth is required, it takes time and production efficiency is low. In particular, in the case of glove removal, the work of turning back the periphery of the bag mouth has to be performed manually, which is a problem in terms of productivity. Furthermore, in the bag in which the reinforcing member such as cardboard is used, there is an inconvenience that the material cost of the reinforcing member is increased and the work of putting the cardboard is troublesome.
The present invention has been made in consideration of such circumstances, and not only the strength of the periphery of the bag mouth is high, but also the strength improvement can be freely adjusted, and the embossing applied to the outer surface of the bag In order to increase the strength of the peripheral edge of the bag mouth without causing the problem that the pattern or picture pattern overlaps with the transparent pattern of the folded portion and looks unnatural and does not require the work of folding the peripheral edge of the bag mouth. An object of the present invention is to provide a bag that does not require the use of a separate reinforcing member.

すなわち本発明は、
不織布からなる袋であって、袋口の周縁に、より厚肉の帯状の強化部を設けてなり、該強化部は、袋本体の繊維材料と同一の繊維材料からなる界面を有しない単一の連続組織からなり、且つ、袋本体の厚さよりもより厚く、袋本体の厚さのおよそ４倍までの厚さを有することを特徴とする、不織布袋に関する。
また本発明は、強化部に取手が形成されているか、或いは、強化部に手提げ紐が取着されている、上記の不織布袋に関する。 That is, the present invention
A bag made of non-woven fabric, which is provided with a thicker band-shaped reinforcing portion at the periphery of the bag mouth, and the reinforcing portion has a single interface that does not have an interface made of the same fiber material as the fiber material of the bag body The present invention relates to a non-woven bag characterized in that it has a continuous structure and is thicker than the thickness of the bag body and has a thickness up to about 4 times the thickness of the bag body.
Moreover, this invention relates to said nonwoven fabric bag in which the handle is formed in the reinforcement | strengthening part, or the hand strap is attached to the reinforcement | strengthening part.

本発明の不織布からなる袋は、袋口の周縁により厚肉の帯状の強化部を設けてなることによって該周縁の強度が高められ、それにより、袋を繰り返して使用したことによる周縁の擦り切れ又はほころびが効果的に抑えられる。のみならず、本発明の袋において、強化部は、袋本体の繊維材料と同一の繊維材料からなる界面を有しない単一の連続組織からなる構造を有する。そのため、袋口の周縁を折り返して作られた界面を有する連続していない上記従来の袋における補強部構造と比べて、同じ厚さにおける強度がより高く、しかも、その強度向上を、強化部の厚さの変更により自在に調節することができる。さらには、周縁を折り返すものでないため、その部分のエンボス模様又は絵模様が内側から透けて見え袋外面のエンボス模様又は絵模様の外観を損なうという不具合が起きず、意匠的効果において有利である。また、袋口の周縁を折り返す作業をなす必要もなく、また袋口の周縁に補強部材を挿入する作業をなす必要もないため、製造の面で高い生産性が得られ、その分生産コストを低下させることができる。さらに、取手又は手提げ紐が強化部に形成され又は取着されることにより、袋に物品を収納して持ち運ぶときでも、物品の重さにより取手の形成部分又は手提げ紐の取着部分に切れ目が入ったり破れたりしてしまうことが効果的に防止される。 In the bag made of the nonwoven fabric of the present invention, the strength of the peripheral edge is increased by providing a thick band-shaped reinforcing portion at the peripheral edge of the bag mouth, and thereby the peripheral edge is worn out by repeatedly using the bag or Breaks are effectively suppressed. In addition, in the bag of the present invention, the reinforcing portion has a single continuous structure that does not have an interface made of the same fiber material as that of the bag body. Therefore, the strength at the same thickness is higher than that of the reinforcing portion structure in the above-described conventional bag having an interface formed by folding the periphery of the bag mouth, and the strength improvement of the reinforcing portion It can be adjusted freely by changing the thickness. Furthermore, since the peripheral edge is not folded back, the embossed pattern or picture pattern of the part can be seen through from the inside, and the problem of impairing the appearance of the embossed pattern or picture pattern on the outer surface of the bag does not occur, which is advantageous in design effect. In addition, there is no need to fold the periphery of the bag mouth, and there is no need to insert a reinforcing member at the periphery of the bag mouth, so that high productivity can be obtained in terms of manufacturing, and the production cost can be reduced accordingly. Can be reduced. Furthermore, when the handle or the hand strap is formed or attached to the reinforcing portion, even when the article is stored in the bag and carried, there is a break in the handle forming part or the hand strap attaching part due to the weight of the article. It is effectively prevented from entering or tearing.

本発明の袋を、その一態様を図示した図１ないし図３に基づいて説明する。
本発明の不織布からなる袋１は、袋の最も弱い箇所である袋口２の周縁３の強度を高めるために、該周縁３に、より厚肉の帯状の強化部４を設けてなる。そして強化部４は、袋本体５の繊維材料と同一の繊維材料からなる界面を有しない単一の連続組織からなるという特徴をさらに有する（図１中のＡ部分の断面図である図２参照。）。つまり強化部４はもともとより厚肉とされており、袋本体５を折り返した部分でなく、また袋本体５と同一の繊維材料以外の他の材料、例えば厚紙やプラスチックシートなどの材料が挿入されているものではなく、袋本体５と連続して形成されており、且つ、強化部４の断面は単層構造であって別の層構造を有しないものである。従って、この構造上の特徴によって、強化部４の外面のエンボス模様６及び絵模様７については、折り返し部分のエンボス模様６’及び絵模様が透けて見えて外観を損なわれるという不具合が起きず、意匠的効果において有利である（図１中のＡ部分の拡大図である図３をも参照。）。
また、強化部４の厚さｗ１は、所定の回数繰り返して使用した後であっても（例えば、
袋１を買物袋としておよそ２０回繰り返して使用した後であっても、）、袋口２の周縁３から裂け目が入って袋としての機能を損なうことがないような範囲の厚さ、おおむね、袋本体５の厚さｗ２よりもより厚く、袋本体５の厚さｗ２のおよそ４倍までの厚さに設定される（図２参照。）。強化部４の厚さｗ１が袋本体の厚さｗ２よりもより薄いと、所定の強度が得られない。また強化部４の厚さｗ１が袋本体の厚さｗ２の４倍を超えると、袋１の材料をより多く必要とするため、生産コストの面で好ましくない。すなわち好ましいのは、強化部４の厚さｗ１が袋本体の厚さｗ２よりも厚く、且つ３倍までの袋である。そして、強化部４の厚さｗ１を変えることにより、袋口の強度を向上を自在に調節することができる。
また、本発明においては、好ましくは、強化部４に取手８を形成するのがよい。これにより、取手８の形成部分に切れ目が入ったり又は破れたりすることが効果的に防止される。取手８の代わりに手提げ紐を強化部４に取着するのもよい。
かような本発明の袋１とは対照的に異なって、例えば従来の袋１９は、補強部２３の断面において、折り返し部分と袋本体との間に非連続の界面ｂ１を有するものであり、連続組織からなるものではない（図８参照。）。また、例えば従来の袋２３は、折り返し部分と袋本体との間に非連続の界面ｂ２を有し、且つ、その部分に厚紙２７を挿入するものであり、即ち、同一の繊維材料からなるものでも、単一の連続組織からなるものでもない（図１１参照。）。そのため従来の袋においては、折り返し部分の模様が外面に写し出される、或いは生産性が悪く高費用である等の不都合を生じるものである。 The bag of the present invention will be described with reference to FIGS.
The bag 1 made of the nonwoven fabric of the present invention is provided with a thicker band-shaped reinforcing portion 4 on the peripheral edge 3 in order to increase the strength of the peripheral edge 3 of the bag mouth 2 which is the weakest part of the bag. And the reinforcement | strengthening part 4 has further the characteristic that it consists of a single continuous structure which does not have the interface which consists of the same fiber material as the fiber material of the bag main body 5 (refer FIG. 2 which is sectional drawing of the A section in FIG. 1). .) That is, the reinforcing portion 4 is originally thick, and is not a portion where the bag body 5 is folded, and other materials other than the same fiber material as the bag body 5, such as a material such as cardboard or a plastic sheet, are inserted. The cross section of the reinforced portion 4 has a single layer structure and does not have another layer structure. Therefore, due to this structural feature, the embossed pattern 6 and the picture pattern 7 on the outer surface of the reinforced portion 4 do not have a problem that the embossed pattern 6 ′ and the picture pattern of the folded portion can be seen through and the appearance is impaired. This is advantageous in terms of design effect (see also FIG. 3 which is an enlarged view of portion A in FIG. 1).
In addition, the thickness w1 of the reinforced portion 4 can be determined after repeated use a predetermined number of times (for example,
Even after the bag 1 is used as a shopping bag repeatedly about 20 times), the thickness of the range that does not impair the function of the bag due to a rip from the peripheral edge 3 of the bag mouth 2, The thickness is set to be thicker than the thickness w2 of the bag body 5 and up to about 4 times the thickness w2 of the bag body 5 (see FIG. 2). When the thickness w1 of the reinforced portion 4 is thinner than the thickness w2 of the bag body, a predetermined strength cannot be obtained. If the thickness w1 of the reinforced portion 4 exceeds 4 times the thickness w2 of the bag body, more material for the bag 1 is required, which is not preferable in terms of production cost. That is, a bag having a thickness w1 of the reinforcing portion 4 larger than the thickness w2 of the bag body and up to three times as much is preferable. And the intensity | strength of a bag mouth can be freely adjusted by changing the thickness w1 of the reinforcement | strengthening part 4. FIG.
In the present invention, it is preferable to form a handle 8 on the reinforced portion 4. Thereby, it is effectively prevented that the cut portion is cut or torn in the formation portion of the handle 8. Instead of the handle 8, a hand strap may be attached to the reinforcing portion 4.
Unlike the bag 1 of the present invention, for example, the conventional bag 19 has a discontinuous interface b1 between the folded portion and the bag body in the cross section of the reinforcing portion 23, It does not consist of a continuous tissue (see FIG. 8). Further, for example, the conventional bag 23 has a discontinuous interface b2 between the folded portion and the bag body, and the cardboard 27 is inserted into the portion, that is, the same fiber material. However, it does not consist of a single continuous tissue (see FIG. 11). Therefore, in the conventional bag, the pattern of the folded portion is projected on the outer surface, or the inconvenience such as low productivity and high cost is caused.

本発明の不織布からなる袋は例えば、ポリエステルなどの不織布用繊維から、強化部に相当する部分がより厚肉となるように不織布シートを製造した後、該シートを適当な寸法に切断し、得られたシート片を二つ折りにし、さらに袋状となるように側縁を縫着又は熱溶着することにより作ることができる。
本発明において用いられる不織布の材料としては、例えば、ポリエステル系繊維、ポリアミド系繊維（ナイロン繊維）、ポリプロピレン系繊維、ポリエチレン系繊維、ポリプロミックス系繊維、ポリクラール系繊維等の合成繊維、ビスコース繊維、銅アンモニアレーヨン等の再生繊維及びアセテート繊維等の半合成繊維等を挙げることができる。 A bag made of the nonwoven fabric of the present invention is obtained by, for example, manufacturing a nonwoven fabric sheet from a nonwoven fabric fiber such as polyester so that the portion corresponding to the reinforced portion becomes thicker, and then cutting the sheet into an appropriate size. The obtained sheet piece can be folded in half, and the side edges can be sewn or heat welded so as to form a bag.
Examples of the material of the nonwoven fabric used in the present invention include polyester fibers, polyamide fibers (nylon fibers), polypropylene fibers, polyethylene fibers, polypromix fibers, polyclar fibers, and other synthetic fibers, viscose fibers, Examples thereof include regenerated fibers such as copper ammonia rayon and semi-synthetic fibers such as acetate fibers.

以下、実施例において本発明の不織布からなる袋を具体的に挙げて説明するが、いかなる場合であっても本発明を限定するものと解釈してはならない。 Hereinafter, in the examples, a bag made of the nonwoven fabric of the present invention will be specifically described. However, it should not be construed as limiting the present invention in any case.

実施例１
本実施例においては、上述の図１ないし図３に示すポリプロピレン（ＰＰ）製の不織布からなる袋１を挙げる。
袋１は、袋口２の周縁３に、袋本体５より厚肉の帯状の強化部４を設けてなる。袋本体５の厚さ（図２中のｗ２）がおよそ０．２ｍｍであるのに対し、袋口２の周縁３における帯状（幅およそ６ｃｍ）の強化部４の厚さ（図３中のｗ１）はおよそ０．６ｍｍであり、強化部４は袋本体５よりもより３倍厚肉である。また、強化部４のほぼ中央には、長径およそ６ｃｍの略楕円状の切り抜かれた取手８を形成している。
袋１のＡ部分における断面図の図２に示すように、強化部４には、界面の存在が観察されていない。強化部４の内面のエンボス模様６’が外面のエンボス模様６に対しずれた配置で外側より透けて見えることがなく、また強化部４の外面の絵模様７についても、折り返し構造でないため、内面の絵模様と重なって透けて見えることはなく、従って絵模様７の外観は袋全体において良好なものである。
而して、袋１を買物袋として２０回使用したところ、袋口２の周縁３及び取手８において、袋としての機能を損なう程の切れ目又は裂け目は見られなかった。 Example 1
In this embodiment, a bag 1 made of a nonwoven fabric made of polypropylene (PP) shown in FIGS.
The bag 1 is provided with a band-shaped reinforcing portion 4 that is thicker than the bag body 5 at the periphery 3 of the bag mouth 2. Whereas the thickness of the bag body 5 (w2 in FIG. 2) is about 0.2 mm, the thickness of the band-like (width about 6 cm) reinforcing portion 4 at the periphery 3 of the bag mouth 2 (w1 in FIG. 3). ) Is approximately 0.6 mm, and the reinforcing portion 4 is three times thicker than the bag body 5. Further, a substantially oval cut handle 8 having a major axis of about 6 cm is formed at substantially the center of the reinforced portion 4.
As shown in FIG. 2 of the cross-sectional view of the A portion of the bag 1, the presence of the interface is not observed in the reinforced portion 4. The embossed pattern 6 ′ on the inner surface of the reinforced portion 4 is not seen through from the outer side by being displaced with respect to the embossed pattern 6 on the outer surface, and the picture pattern 7 on the outer surface of the reinforced portion 4 is not folded. Therefore, the appearance of the picture pattern 7 is good in the entire bag.
Thus, when the bag 1 was used 20 times as a shopping bag, no breaks or tears that would impair the function of the bag were found in the peripheral edge 3 and the handle 8 of the bag mouth 2.

実施例２
本実施例は、図４ないし６に示す本発明の別態様の不織布からなる袋９である。
ＰＰ製の袋９は、長さおよそ３５ｃｍ、幅およそ２５ｃｍを有する縦長の構造のものである。袋９には、その袋口１０の周縁１１において、より厚肉の幅およそ６ｃｍの帯状の強化部１２を設けてなり、周縁１１の強度向上が図られている。具体的には、強化部１２の厚さｗ３（図４中のＢ部分の断面図である図５参照。）はおよそ０．４ｍｍを有し、袋本体１３の厚さ（図５中のｗ４）およそ０．２ｍｍと比べておよそ２倍となるように設計されている。また強化部１２は袋本体１３と同一の繊維材料であるＰＰからなる。袋９にはエンボス模様１４が施され、そしてその外面には絵模様１５が施され、さらに、その強化部１２において手提げ紐１６が鳩目１７によって取着されている。更に、袋９には、物品を収納したときに該物品の位置が安定しやすく、持ち運びしやすいように、底部において幅広のまち１８が設けられている。
強化部１２の断面図の図５に示すように、界面を有しない単一の連続組織からなることが観察される。強化部１２のエンボス模様１４は外面と内面とでずれ乱れた配置で透けて見えることもなく、また強化部１２も、折り返し構造でないため、内面の模様と重なって透けて見えることはなく、従って絵模様１５の外観は袋全体において良好である。
而して、袋９を買物袋として２０回使用したところ、袋口１０の周縁１１及び手提げ紐１６の取着部分において、袋としての機能を損なう程の切れ目又は裂け目は見られなかった。 Example 2
A present Example is the bag 9 which consists of a nonwoven fabric of another aspect of this invention shown to FIG.
The PP bag 9 has a vertically long structure having a length of about 35 cm and a width of about 25 cm. The bag 9 is provided with a thicker belt-like reinforcing portion 12 having a width of about 6 cm at the peripheral edge 11 of the bag mouth 10 to improve the strength of the peripheral edge 11. Specifically, the thickness w3 of the reinforced portion 12 (see FIG. 5 which is a cross-sectional view of portion B in FIG. 4) is approximately 0.4 mm, and the thickness of the bag body 13 (w4 in FIG. 5). ) It is designed to be about twice as large as about 0.2 mm. The reinforcing part 12 is made of PP, which is the same fiber material as the bag body 13. An embossed pattern 14 is applied to the bag 9, and a picture pattern 15 is applied to the outer surface of the bag 9, and a hand strap 16 is attached to the reinforcing portion 12 by eyelets 17. Further, the bag 9 is provided with a wide town 18 at the bottom so that when the article is stored, the position of the article is easy to stabilize and easy to carry.
As shown in FIG. 5 of the sectional view of the reinforced portion 12, it is observed that the reinforcing portion 12 is composed of a single continuous structure having no interface. The embossed pattern 14 of the reinforced portion 12 is not seen through in a dislocation arrangement between the outer surface and the inner surface, and the reinforced portion 12 is also not a folded structure, so it does not appear overlapping with the pattern on the inner surface. The appearance of the picture pattern 15 is good throughout the bag.
Thus, when the bag 9 was used 20 times as a shopping bag, no breaks or tears that would impair the function of the bag were found in the peripheral edge 11 of the bag mouth 10 and the attachment portion of the hand strap 16.
