Description

本発明は、購入した商品を持ち返るための買物袋に関する。詳しくは、重い荷物を入れても繰り返し使用可能であり、軽量かつコンパクトで、さらにリサイクルが容易な買物袋に関する。   The present invention relates to a shopping bag for bringing back purchased merchandise. More specifically, the present invention relates to a shopping bag that can be used repeatedly even when a heavy load is placed, is lightweight and compact, and is easy to recycle.

現在、顧客がスーパー等の小売店で購入した商品を持ち帰る手段として、無料で配布される樹脂フィルム製の買物袋が主に使用されている。そして中でも広く利用されているのは、低密度ポリエチレンの薄いフィルムを溶着して袋状に製造された買物袋である。しかしながら、この種の買物袋は伸び耐性が低く、重い商品を詰め手提げると、樹脂フィルムがたやすく延伸して該買物袋が裂けたり変形したりしてしまい、このため該樹脂フィルム製買物袋は多くの場合使い捨てで使用されている。   Currently, shopping bags made of resin film that are distributed free of charge are mainly used as a means for customers to take home merchandise purchased at retail stores such as supermarkets. Among them, a shopping bag manufactured in a bag shape by welding a thin film of low density polyethylene is widely used. However, this type of shopping bag has low resistance to elongation, and if a heavy product is packed, the resin film easily stretches and the shopping bag is torn or deformed. For this reason, the resin film shopping bag is used. Are often used disposable.

樹脂フィルム製買物袋は石油を原料として製造されるものであるので、その使い捨ては、貴重な石油資源の浪費に繋がる。また、樹脂フィルム製買物袋には一般に種々の添加剤が配合されるため、これを焼却により処分すると、例えばダイオキシン、ＣＯ2等の有害
なガスの発生源となる。さらに、樹脂フィルム製買物袋の燃焼の際に生じる二酸化炭素は、温室効果ガスとも呼ばれ、地球温暖化の原因となることが知られている。以上のような理由から、樹脂フィルム製買物袋の使い捨てという使用態様は環境保全・資源節約の観点より非常に好ましくない。 Since the resin film shopping bag is manufactured using petroleum as a raw material, its disposable use leads to a waste of valuable petroleum resources. In addition, since various additives are generally blended in the shopping bag made of resin film, if it is disposed of by incineration, it becomes a source of harmful gases such as dioxin and CO 2 . Furthermore, carbon dioxide produced during the burning of a resin film shopping bag is also called a greenhouse gas and is known to cause global warming. For the reasons described above, the use mode of disposable resin film shopping bags is very undesirable from the viewpoint of environmental conservation and resource saving.

そこで最近、小売店では、斯かる事情を考慮し、今まで無料で配布していた買物袋を有料にする、買物袋が必要でない人には現金と引き換えることができるスタンプやクーポンを発行する等の方法により、顧客自身が買物袋を持参することを推奨している。しかしながら、従来、買物袋として使用されている布製の袋は厚手で嵩張りまた決して軽量とは言えず、携帯には適していなかった。さらに布製の袋は異質の材料で出来ておりリサイクルに適しておらず、また相当に高価なものでもあった。
そこで、本発明者は、この課題を解決するために、本願より以前に主にポリエステル樹脂製の不織布を同じポリエステル樹脂製の糸で袋状に縫製して製造した買物袋を提案している（特許文献１）。
特開２００３−１３７３０４号公報 Therefore, recently, in consideration of such circumstances, retail stores charge shopping bags that have been distributed free of charge, and issue stamps and coupons that can be exchanged for cash for those who do not need shopping bags. Etc., it is recommended that customers bring their own shopping bags. Conventionally, however, cloth bags used as shopping bags are not thick, bulky, and lightweight, and are not suitable for carrying. Furthermore, cloth bags were made of different materials and were not suitable for recycling, and were also quite expensive.
Therefore, in order to solve this problem, the present inventor has proposed a shopping bag manufactured by sewing a polyester resin nonwoven fabric into a bag shape with the same polyester resin thread before the present application ( Patent Document 1).
JP 2003-137304 A

しかしながら、前記ポリエステル樹脂不織布の買物袋は、該買物袋全体が同じ厚みからなる不織布で作られており、重い荷物を入れたり、数回使用すると、荷重が最も加わる該買物袋の取手部分が切れたり、延びたりするという問題があった。また、ポリエステル樹脂の回収、再生及び再利用というリサイクル化は現在種々の問題があり、現状においてリサイクル化が十分に確率しているとはいえない。
従って、重い荷物を入れても取手部分が延びたり、切れたりせず、繰返し使用することができる程十分な強度を有し、軽量かつコンパクトで携帯に適しており、かつリサイクルが容易である新たな買物袋を考慮する必要があった。 However, the shopping bag of the polyester resin non-woven fabric is made of a non-woven fabric having the same thickness as a whole, and the handle portion of the shopping bag to which the load is most applied is cut when a heavy load is put or used several times. There was a problem of extending or extending. In addition, there are various problems with recycling of polyester resin such as recovery, regeneration, and reuse, and it cannot be said that recycling is sufficiently probable at present.
Therefore, even if a heavy load is put in, the handle part does not extend or break, and it is strong enough to be used repeatedly, lightweight, compact, suitable for carrying, and easy to recycle. It was necessary to consider a shopping bag.

そこで、本発明者等は鋭意検討を行った結果、ポリエステル樹脂に代えてポリオレフィン樹脂製の不織布を折り畳み及びヒートシール加工して製造した買物袋とし、かつその袋の取手部分を含む袋上部を単一層の厚肉不織布で構成することによって強度が著しく改良
され、しかもリサイクル化が容易であり、よって上記課題が解決されうることを見出して本発明を完成させた。
本発明は、以下の（１）ないし（４）の小売店で配布される買物袋に関する。

（４）前記買物袋の長さ方向に関して前記厚肉不織布からなる部分の長さが、袋全長の１／５ないし１／３であることを特徴とする、前記（１）ないし（３）のいずれか１項に記載の買物袋。 Accordingly, as a result of intensive studies, the present inventors have made a shopping bag manufactured by folding and heat-sealing a non-woven fabric made of polyolefin resin instead of polyester resin, and the upper portion of the bag including the handle portion of the bag is simply formed. The present invention has been completed by finding out that the strength is remarkably improved by constituting it with one thick thick non-woven fabric and that it is easy to recycle, and that the above problems can be solved.
The present invention relates to shopping bags distributed at retail stores (1) to (4) below.
(1) a bag lower portion having a bottom portion extending in a linear shape and extending;
Left and right bag sides folded inside and having gussets;
A bag upper portion that forms a pair of folded wide handle portions;

(4) The length of the thick nonwoven fabric with respect to the length direction of the shopping bag is 1/5 to 1/3 of the total length of the bag, (1) to (3) The shopping bag of any one of Claims.

本発明の買物袋は、ポリオレフィン不織布から作られ、取手部を含む袋上部を単一層の厚肉不織布で構成したことにより、厚肉部の無い従来の不織布買物袋と比較して十分に高い強度を有し、繰り返しの使用に十分に耐えることができる。また軽量でかつ折畳むこともできるので、非常に携帯し易く、買物袋を持参することの煩わしさを大幅に減ずることが可能である。さらに、本発明の買物袋は再生が容易なポリオレフィン不織布で構成されているため、回収し、再生しそして再利用するという循環を作るためのリサイクル化が容易である。   The shopping bag of the present invention is made of a polyolefin nonwoven fabric, and the upper portion of the bag including the handle portion is composed of a single layer thick nonwoven fabric, so that it has sufficiently high strength compared to a conventional nonwoven shopping bag without a thick portion. And can sufficiently withstand repeated use. Moreover, since it is lightweight and can be folded, it is very easy to carry and the troublesomeness of bringing a shopping bag can be greatly reduced. Furthermore, since the shopping bag of the present invention is made of a polyolefin nonwoven fabric that can be easily recycled, it can be easily recycled to create a circulation that can be recovered, recycled, and reused.

本発明の買物袋は、線状に閉じて伸びる底辺部を有する袋下部、内側に折り畳まれてマチを有する左右の袋側部及び折り重ねられた幅広の取手部を一対で形成する袋上部を備えてなるものである。
また、本発明の買物袋には、リサイクルの容易さ、強度、成形性等の面から、ポリエチレン不織布、ポリプロピレン不織布などのポリオレフィン不織布が使用される。なかでも、再生が容易なポリプロピレン不織布が好ましい。
また、本発明に用いられる前記不織布は、無着色のもの、又は慣用の不織布染色技術、例えばビーム染色、液流染色、ディッピングなどの染色法によって染色したものを用いることができる。染色した不織布によって製造された本発明の買物袋をリサイクルにより再利用する場合、色別に分別回収し、各々再生することによって、回収された袋材料を脱色することなくそれより新たな買物袋を再生産することができる。ゆえに、本発明の買物袋を配布する小売店ごとに識別、宣伝等のために色分けされた該買物袋を採用すると、それを色別に分別し回収するだけで容易に再生しそして再利用することができ、なおかつ小売店にとっては、自己の店の色の買物袋の持参を消費者に促すことで、繰り返しの来店を期待できるという利点がある。 The shopping bag of the present invention comprises a bag lower portion having a bottom portion extending in a linear shape, a left and right bag side portion folded inward and having a gusset, and a bag upper portion forming a pair of folded wide handle portions. It is prepared.
Moreover, polyolefin nonwoven fabrics, such as a polyethylene nonwoven fabric and a polypropylene nonwoven fabric, are used for the shopping bag of this invention from surfaces, such as recyclability, intensity | strength, and a moldability. Among these, a polypropylene nonwoven fabric that can be easily recycled is preferable.
Moreover, the said nonwoven fabric used for this invention can use a non-colored thing or the thing dye | stained by dyeing methods, such as beam dyeing, liquid flow dyeing, and dipping, for example, the usual nonwoven fabric dyeing technique. When recycling the shopping bags of the present invention manufactured by dyed non-woven fabrics by recycling, they can be collected separately by color and recycled to recycle newer shopping bags without decoloring the collected bag materials. Can be produced. Therefore, if the shopping bags color-coded for identification, promotion, etc. are adopted for each retail store that distributes the shopping bags of the present invention, they can be easily regenerated and reused simply by sorting and collecting them by color. In addition, retailers have the advantage that they can expect repeated visits by encouraging consumers to bring their own color shopping bags.

また、本発明の買物袋は袋上部の全体又は少なくとも取手部を含む一部が、該買物袋のその他の部分の厚さと比較して１．１倍以上の厚さを有するものであるので、荷物の重量に耐えるに十分な引張強さ及び引裂強さを与えることができる。さらに十分高い強度を与えるためには、該買物袋における前記袋上部の全体又は少なくとも前記取手部を含む一部
が、該買物袋のその他の部分の厚さと比較して１．８倍ないし３．０倍の厚さを有することが好ましい。また本発明の買物袋において厚肉となる部分は、不織布を二層にするなど複数の層を重ねることで厚肉としたものではなく、単一層からなるものである。よって、二層重ねの構成と比較して、強度の著しい改良がみられる。さらに、買物袋の長さ方向に関して前記厚肉部分の長さが、袋全長の１／５ないし１／３であることが好ましい。
次に、本発明の買物袋の製造法を述べる。
例えば、長辺方向の中央部が両端部に比して厚肉となる不織布を用いる場合、その長辺に直交する方向で該長方形を二分する折り目に沿って折り畳み、そして該折り目を含む不織布の一部を切除して取手及び封止片を形成し、次に前記長方形の長辺であった辺に沿って該不織布をヒートシールして袋側部を作成し、シールした袋側部を内側に折り返し、取手及び封止片に対向する短辺に沿って袋本体と同材質の糸でミシン縫製、或いはヒートシールして袋の底部を作成し、そして得られた袋を折り返すことにより本発明のポリオレフィン製不織布買物袋が得られる。
また、例えば、長辺方向の両端部が中央部に比して厚肉となる不織布を用いる場合、その長辺に直交する方向で該長方形を二分する折り目に沿って折り畳み、そして該折り目に対向する不織布の両端部（厚肉部）を重ねてヒートシールして、さらにシールした端縁を含む不織布厚肉部の一部を切除して取手及び封止片を形成し、次に前記長方形の長辺であった辺に沿って該不織布をヒートシールして袋側部を作成し、シールした該袋側部を内側に折り返し、そして得られた不織布を裏返して、取手及び封止片に対向する辺に沿って袋本体と同材質の糸でミシン縫製、或いはヒートシールして袋の底部を作成することにより本発明のポリオレフィン製不織布買物袋が得られる。
本発明の買物袋の製造方法は、上記以外の異なる方法によっても得られる。 In addition, the shopping bag of the present invention has a thickness of 1.1 times or more in comparison with the thickness of the whole of the upper part of the bag or at least part of the handle part compared with the thickness of the other part of the shopping bag. Sufficient tensile and tear strength can be provided to withstand the weight of the load. In order to give a sufficiently high strength, the entire upper portion of the shopping bag or at least a portion including the handle portion of the shopping bag is 1.8 times to 3 times the thickness of the other portion of the shopping bag. It is preferable to have a thickness of 0 times. In addition, the thickened portion of the shopping bag of the present invention is not made thick by overlapping a plurality of layers, such as making a nonwoven fabric into two layers, but consists of a single layer. Thus, a significant improvement in strength is seen compared to the two-layer construction. Furthermore, it is preferable that the length of the thick portion in the length direction of the shopping bag is 1/5 to 1/3 of the total length of the bag.
Next, the manufacturing method of the shopping bag of this invention is described.
For example, when using a nonwoven fabric in which the central portion in the long side direction is thicker than both end portions, fold along the fold that bisects the rectangle in the direction perpendicular to the long side, and the nonwoven fabric including the fold line A part is cut off to form a handle and a sealing piece, and then the non-woven fabric is heat-sealed along the long side of the rectangle to create a bag side, and the sealed bag side is inside The bottom of the bag is created by sewing or heat-sealing with a thread made of the same material as the bag body along the short side facing the handle and the sealing piece, and the bag is folded back to obtain the present invention. A polyolefin non-woven shopping bag is obtained.
In addition, for example, when using a nonwoven fabric in which both ends in the long side direction are thicker than the center part, fold along the fold that bisects the rectangle in a direction perpendicular to the long side, and face the fold. And heat seal the both ends (thick part) of the nonwoven fabric to be cut, further cut off a part of the thick part of the nonwoven fabric including the sealed edge to form a handle and a sealing piece, The non-woven fabric is heat-sealed along the long side to create a bag side portion, the sealed bag side portion is folded inside, and the obtained non-woven fabric is turned over to face the handle and the sealing piece. The polyolefin non-woven shopping bag of the present invention can be obtained by sewing a sewing machine with a thread made of the same material as that of the bag body along the side of the bag or heat sealing to form the bottom of the bag.
The shopping bag manufacturing method of the present invention can also be obtained by a different method other than the above.

本発明の買物袋は、ポリオレフィン不織布からなりかつ取手を含む該買物袋の一部を厚肉としたことにより、従来のものより格段に荷物の重量に耐えるに十分な引張強さ及び引裂強さを有するものとなった。本発明の買物袋は、通常１０ないし２０回程度、繰り返して使用することができる。また、本発明に用いられるポリオレフィン不織布は軽量であり、しかもコンパクトに折り畳むこと、並びに折畳み後に再展開して元の形状に戻すことも容易であるので、本発明のポリオレフィン不織布の買物袋は携帯にも大変適している。
また、本発明の買物袋は、全体が同一のポリオレフィン不織布からなるため、分解分別する必要がないので、そのまま再生工程に送ることができ、ゆえに該買物袋のリサイクル化は非常に容易である。 The shopping bag of the present invention is made of a polyolefin nonwoven fabric and part of the shopping bag including the handle is made thick, so that the tensile strength and tear strength sufficient to withstand the weight of the baggage much more than conventional ones. It became that which has. The shopping bag of the present invention can be used repeatedly, usually about 10 to 20 times. In addition, the polyolefin nonwoven fabric used in the present invention is lightweight, and can be folded compactly, and can be easily re-deployed after folding and returned to its original shape. Therefore, the polyolefin nonwoven fabric shopping bag of the present invention is portable. Is also very suitable.
In addition, since the shopping bag of the present invention is entirely made of the same polyolefin nonwoven fabric, it is not necessary to disassemble and separate it, so that it can be sent to the regeneration process as it is, and therefore the shopping bag can be recycled very easily.

以下に図面を参照して本発明をより詳細に説明する。図１は本発明の買物袋のある態様を図示する斜視図であり、そして図２の（ａ）ないし（ｄ）は、本発明の買物袋の製造過程の一例を図示する模式図である。さらに、図３は図２（ａ）のＡ−Ａ’断面図である。   Hereinafter, the present invention will be described in more detail with reference to the drawings.
