Description

本発明は、フレキシブルコンテナに関し、詳しくは、静電気の帯電を防止するフレキシブルコンテナに関する。 The present invention relates to a flexible container, and more particularly to a flexible container that prevents static electricity from being charged.

従来、合成樹脂ペレット、セメント等の粉粒体の移送には、熱可塑性合成樹脂製の布状体で構成されたフレキシブルコンテナが広く使用されている。 Conventionally, a flexible container composed of a cloth-like body made of a thermoplastic synthetic resin has been widely used for transferring powder particles such as synthetic resin pellets and cement.

フレキシブルコンテナは、布状体で形成された袋本体の下部又は下部と上部に移送物を充填、排出するための開口部が形成され、上部には吊りベルトが取り付けられてクレーンのフック等の吊り上げ治具で吊り上げて作業ができるように形成されており、フレキシブルコンテナは、可撓性の布状体であることから、軽量で、強靭であり、衝撃に強い特徴を有する。 The flexible container has an opening for filling and discharging the transported material in the lower part or lower part and upper part of the bag body formed of a cloth-like body, and a lifting belt is attached to the upper part to lift crane hooks etc. It is formed so that it can be lifted by a jig and can be operated, and since the flexible container is a flexible cloth-like body, it is lightweight, tough, and has a strong characteristic against impact.

しかし、粉粒体の投入時、あるいは排出時においては、粉粒体間、あるいは、粉粒体とフレキシブルコンテナ間に摩擦が生じ、静電気が発生し易い問題がある。フレキシブルコンテナに静電気が発生すると、収容物がフレキシブルコンテナに貼り付いて落下せず、内部に残留するものが生じ、次の収容物に異物として混じることになり、商品の品質低下を招く原因となる。 However, at the time of charging or discharging the powder, there is a problem that friction is generated between the powder or between the powder and the flexible container, and static electricity is easily generated. When static electricity is generated in the flexible container, the contents are stuck to the flexible container and do not fall, and some of the contents remain inside, and are mixed as foreign matter in the next container, causing a reduction in product quality. .

更に、静電気放電の際の火花に起因して、粉塵爆発等の災害を引き起こす恐れもある。 Furthermore, there is a risk of causing a disaster such as a dust explosion due to sparks during electrostatic discharge.

従来、静電気対策用のフレキシブルコンテナとして、特許文献１には、導電性線状体が配設された布状体からなるコンテナ本体と、同様に導電性線条体が配設された布状体からなる吊りベルトとが縫製にて結合され、コンテナ本体の表面に露出する導電性線条体と吊りベルトの表面に露出する導電性線条体とが互いに接触して電気的に接合されるようにしたものが提案されている。このコンテナ本体の導電性線条体と吊りベルトの導電性線条体との間の電気的な結合を確実にするために、これらコンテナ本体と吊りベルトとの間に導電性シートを介装することが記載されている。 Conventionally, as a flexible container for countermeasures against static electricity, Patent Document 1 discloses a container body made of a cloth-like body in which conductive linear bodies are arranged, and a cloth-like body in which conductive filaments are similarly arranged. So that the conductive filaments exposed on the surface of the container body and the conductive filaments exposed on the surface of the suspension belt come into contact with each other and are electrically joined together. What has been proposed is proposed. In order to ensure the electrical coupling between the conductive filaments of the container body and the conductive filaments of the suspension belt, a conductive sheet is interposed between the container body and the suspension belt. It is described.

また、特許文献２には、フレキシブルコンテナを構成する導電性基布間に、シート状の導電性織物若しくは編物又は導電性不織布を介装することが記載されている。 Patent Document 2 describes that a sheet-like conductive fabric or knitted fabric or a conductive nonwoven fabric is interposed between the conductive base fabrics constituting the flexible container.

一般にフレキシブルコンテナは、コンテナ本体と吊りベルトとを縫合糸を用いてミシンによって縫製することによって一体化している。また、コンテナ本体自体も、布状体等を用いて袋状に縫製することによって形成している。静電気対策用のフレキシブルコンテナは、コンテナ全体に亘る導電性を確保する観点から、このような各縫製部位において導電性線条体同士の確実な電気的結合が必要とされるが、導電性線条体同士の接触では線と線との接触となって確実な電気的結合を得ることが難しい。特許文献１、２では、縫製部位に導電性シート状体を挟むことで、線と面との接触を行うようにしているが、単に導電性シート状体を介装して線と面との接触を図っても、特にコンテナ本体と吊りベルトとの縫製部位では、次のような理由によって信頼性の高い電気的結合を得ることが困難であった。 Generally, a flexible container is integrated by sewing a container body and a suspension belt with a sewing machine using a suture thread. Further, the container body itself is also formed by sewing in a bag shape using a cloth-like body or the like. From the viewpoint of ensuring conductivity throughout the container, a flexible container for countermeasures against static electricity requires a reliable electrical connection between the conductive filaments at each sewing site. In contact between bodies, it is difficult to obtain reliable electrical coupling due to contact between lines. In Patent Documents 1 and 2, the conductive sheet-like body is sandwiched between the sewing parts to make contact between the line and the surface. However, the conductive sheet-like body is simply interposed between the wire and the surface. Even when contact is made, it is difficult to obtain highly reliable electrical connection for the following reasons, particularly at the sewing site between the container body and the suspension belt.

すなわち、吊りベルトは、大きな吊り上げ荷重に耐え得るだけの高い機械的強度が要求されることから、一般に柔軟なコンテナ本体に比べて肉厚、嵩高で剛性を有している。このため、それ自体はコンテナ本体や導電性シート状体に対して馴染みにくい。特に、吊りベルトがフラットヤーンからなる線条体を用いて織成された布状体からなるものである場合、その表面は織目によって大きな凹凸状となるため、この吊りベルトに配設された導電性線条体は表面の凹凸に埋もれてしまってコンテナ本体側の導電性線条体との密着を図ることが難しい。たとえ間に導電性シート状体を介装したとしても、コンテナ本体の側面は比較的平坦であるのに対し、吊りベルトの表面は大きな凹凸状であるため、導電性シート状体がコンテナ本体の表面に追従した場合は吊りベルトの表面に追従し難く、一方、吊りベルトの表面に追従した場合はコンテナ本体の表面に追従し難くなり、いずれにしても両者の間で確実な密着状態を得ることが難しかった。 That is, since the suspension belt is required to have a high mechanical strength that can withstand a large lifting load, the suspension belt is generally thicker, bulkier and more rigid than a flexible container body. For this reason, it is difficult to adapt itself to the container body or the conductive sheet. In particular, when the suspension belt is made of a cloth-like body woven using a linear body made of flat yarn, the surface becomes a large uneven shape due to the weave, so the suspension belt is disposed on the suspension belt. The conductive filament is buried in the surface irregularities, and it is difficult to achieve close contact with the conductive filament on the container body side. Even if a conductive sheet is interposed, the side surface of the container body is relatively flat, whereas the surface of the suspension belt has a large uneven shape. When following the surface, it is difficult to follow the surface of the suspension belt. On the other hand, when following the surface of the suspension belt, it is difficult to follow the surface of the container body, and in any case, a reliable adhesion is obtained between the two. It was difficult.

また、吊りベルトは幅広に形成され、そこに配設される導電性線条体もベルト幅方向に複数並設されるものが一般的である。フレキシブルコンテナの確実な帯電防止を図るには、吊りベルトに配設される複数本の導電性線条体の全てがコンテナ本体側の導電性線条体又は導電性シート状体と確実に密着して電気的結合を行う必要があるが、上述したように、コンテナ本体側の導電性線条体や導電性シート状体との間の密着性の困難さから、吊りベルト側の全ての導電性線条体を確実にコンテナ本体側の導電性線条体と電気的結合させることは困難であった。 Further, the suspension belt is generally formed wide, and a plurality of conductive filaments arranged there are generally arranged in the belt width direction. In order to ensure the prevention of electrification of the flexible container, all of the plurality of conductive filaments arranged on the suspension belt are securely in close contact with the conductive filament or conductive sheet on the container body side. However, as described above, because of the difficulty of adhesion between the conductive wire on the container body side and the conductive sheet, all the conductivity on the suspension belt side is required. It has been difficult to reliably electrically couple the striated body with the conductive striated body on the container body side.

そこで、本発明の課題は、吊りベルト側に配設された導電性線条体とコンテナ本体側に配設された導電性線条体との間の電気的な結合を、簡単な構成の付加だけで確実に行うことができるようにし、高い帯電防止性能を有するフレキシブルコンテナを提供することにある。 Accordingly, an object of the present invention is to add an electrical connection between the conductive wire disposed on the suspension belt side and the conductive wire disposed on the container body side with a simple configuration. An object of the present invention is to provide a flexible container having high antistatic performance, which can be carried out reliably only by this.

A so-called master batch having a high concentration may be prepared and used after being diluted.

線条体２０ａ、２０ｂとして基層２００と接合層２０１の積層体が使用される場合、成形材料となる積層フィルムを成形する手段としては、予め基層２００となるフィルムと接合層２０１となるフィルムを形成してドライラミネート法や熱ラミネート法を用いて複層化する手段や、基層２００となるフィルムの表面に接合層２０１となる合成樹脂をコーティングする方法、予め形成した基層２００となるフィルムに接合層２０１を押出ラミネートする方法、あるいは、多層共押出法によって積層フィルムとして押出成形するなどの公知の手段から適宜選択して用いることができる。中でも、成形の容易さやコスト面、並びに、製品の各層間の接着性の点では、多層共押出法によって基層２００と接合層２０１の積層体を一段で得る方法が好ましい。 When the laminated body of the base layer 200 and the bonding layer 201 is used as the filaments 20a and 20b, as a means for forming a laminated film as a molding material, a film to be the base layer 200 and a film to be the bonding layer 201 are formed in advance.

The synthetic resin to be the bonding layer 201 may be laminated, and may be slit in a tape shape, or before slitting the laminated film in which the base layer 200 and the bonding layer 201 are laminated, or after slitting, the uniaxial direction It can also be obtained by stretching. The draw ratio is usually about 3 to 10 times.

線条体２０ａ、２０ｂの太さは特に制限はないが、一般には７５〜１００００ｄｔ（デシテックス）、糸幅が０．３〜３０ｍｍの範囲のフラットヤーンとすることができる。こうして得られた一軸延伸フラットヤーンは、縦方向に小さな切れ目を入れてスプリットヤーンとすることもできる。 Although the thickness of the filaments 20a and 20b is not particularly limited, it can generally be a flat yarn having a range of 75 to 10000 dt (decitex) and a yarn width of 0.3 to 30 mm.

Although this thermoplastic resin layer 20c is not essential in the present invention, the gap between the filaments 20a and 20b of the cloth-like body 20 is closed by the thermoplastic resin layer 20c, and therefore the thermoplastic resin layer 20c. By forming the container main body 2 so that the laminated surface becomes the inner surface, it is possible to make a flexible container particularly suitable for accommodating powdery materials.

この熱可塑性樹脂層２０ｃとして使用される樹脂としては、ポリオレフィン、ポリエチレンテレフタレート、ポリブチレンテレフタレート等のポリエステル、ナイロン６、ナイロン６６等のポリアミドを用いることができも中でも、ポリオレフィンが好ましい。ポリオレフィンとしては、エチレン、プロピレン、ブテン−１、ヘキセン−１、オクテン−１、デセン−１等の単独重合体、あるいはこれらを主成分とする共重合体を用いることができる。特に、メタロセン触媒を用いて重合されたポリオレフィン、好ましくはポリエチレン、ポリプロピリン、エチレン・α−オレフィン共重合体を用いることができる。 As the resin used for the thermoplastic resin layer 20c, polyolefin such as polyolefin, polyethylene terephthalate, polyester such as polybutylene terephthalate, and polyamide such as nylon 6 and nylon 66 can be used.

It is preferably in the form of a tape. The width or diameter can be about 3 μm to 10 mm, and the thickness can be about 3 μm to 30 μm.

フラットヤーンからなる第１の導電性線条体４とする場合は、図４（ｃ）に示す線条体の表面層となる接合層２０１のみを導電性樹脂とし、中央の基層２００には導電性を付与させず、この基層２００を例えば高密度ポリエチレン等によって形成して芯材とし、線条体としての強度を保つようにすることが好ましい。 When the first conductive linear body 4 made of flat yarn is used, only the bonding layer 201 serving as the surface layer of the linear body shown in FIG. It is preferable that the base layer 200 is made of, for example, high-density polyethylene to form a core material and maintain the strength as a linear body.

この第１の導電性線条体４は、コンテナ本体２の全面に亘って多数本が布状体２０に配設される。具体的な配設方法としては、織成又は編成後の布状体２０に対して、後作業として、第１の導電性線条体４が表裏に交互に露出するように縫い込むようにしてもよいが、図２に示すように、布状体２０を構成する一部の線条体２０ａ、２０ｂの代わりに経糸及び緯糸として用いることにより、線条体２０ａ、２０ｂと共に一度に布状体２０を織成又は編成することが好ましい。 A large number of the first conductive filaments 4 are arranged on the cloth body 20 over the entire surface of the container body 2. As a specific arrangement method, the first conductive filaments 4 may be sewn to the cloth-like body 20 after weaving or knitting so that the first conductive filaments 4 are alternately exposed on the front and back sides as a post work. However, as shown in FIG. 2, the cloth-like body 20 is used together with the filaments 20a, 20b at a time by using it as warp and weft instead of a part of the filaments 20a, 20b constituting the cloth-like body 20. Weaving or knitting is preferred.

Moreover, the 1st electroconductive wire 4 is not restricted to what is arrange | positioned in the grid | lattice form by equal pitch in the vertical and horizontal of the container main body 2, You may arrange | position so that the vertical and horizontal pitch may each differ.

吊りベルト３は、ベルト本体３０が、図５に示すように、熱可塑性樹脂製の線条体３０ａ、３０ｂを用いて織成又は編成された布状体からなる所定幅の帯状体であり、コンテナ本体２の側面上部に両端が縫合されることによって、コンテナ本体２の上部に、吊り上げ治具（図示せず）等を用いて吊り上げる際の吊り輪部３Ａを形成している。 As shown in FIG. 5, the suspension belt 3 is a belt-like body having a predetermined width made of a cloth-like body woven or knitted using linear bodies 30 a and 30 b made of thermoplastic resin, as shown in FIG. 5. Both ends are sewn to the upper side of the container body 2, thereby forming a suspension ring portion 3 </ b> A for lifting the container body 2 using a lifting jig (not shown) or the like.

ベルト本体３０を構成する布状体は、収容物が充填されたコンテナ本体２の吊り上げ荷重に十分耐え得るだけの機械的強度、特に引張強度を有するものであり、熱可塑性樹脂製の線条体３０ａ、３０ｂを用いて、コンテナ本体２を構成する布状体２０よりも肉厚、嵩高で剛性を有するように形成されている。 The cloth-like body constituting the belt main body 30 has mechanical strength, particularly tensile strength, that can sufficiently withstand the lifting load of the container main body 2 filled with the contents, and is a linear body made of thermoplastic resin. 30 a and 30 b are used to be thicker, bulkier and more rigid than the cloth-like body 20 constituting the container body 2.

ここでは、熱可塑性樹脂製の線条体３０ａとして一軸延伸されたフラットヤーンを使用し、これを吊りベルト３の長さ方向に沿う方向の糸（経糸）とし、熱可塑性樹脂製の線条体３０ｂとしてマルチフィラメントを使用し、これを吊りベルト３の長さ方向と直交する幅方向の糸（緯糸）として使用して織成している。 Here, a flat yarn stretched uniaxially is used as the linear body 30a made of thermoplastic resin, and this is used as a thread (warp) along the length direction of the suspension belt 3, and the linear body made of thermoplastic resin. A multifilament is used as 30b, which is woven by using it as a thread (weft) in the width direction perpendicular to the length direction of the suspension belt 3.

熱可塑性樹脂製の線条体３０ａとしては、コンテナ本体２の布状体２０に使用される線条体２０ａ、２０ｂと同様の一軸延伸された熱可塑性樹脂の基層の単層体又は基層と接合層との積層体からなるフラットヤーンとすることができる。 As the linear body 30a made of a thermoplastic resin, it is joined to a single layer or a base layer of a base layer of a uniaxially stretched thermoplastic resin similar to the linear bodies 20a and 20b used for the cloth body 20 of the container body 2. It can be set as the flat yarn which consists of a laminated body with a layer.

線条体３０ａの太さは特に制限はないが、一般には７５〜１００００ｄｔ、糸幅が０．３〜３０ｍｍの範囲のフラットヤーンとすることが好ましく、特に、機械的強度の高い肉厚で嵩高な吊りベルト３とするためには、このようなフラットヤーンを複数本重ね合せて集束し、１本の線条体３ａを形成することが好ましい。織成する場合の織り方は平織り、綾織りとすることができるが、特にベルト本体３０を形成した時の厚みが３ｍｍ以上の肉厚で嵩高なものとなるように綾織りすることが好ましい。 The thickness of the striate body 30a is not particularly limited, but in general, it is preferably a flat yarn having a range of 75 to 10000 dt and a yarn width of 0.3 to 30 mm. In order to obtain a suspending belt 3, it is preferable that a plurality of such flat yarns are overlapped and converged to form a single filament 3a. The weaving method in the case of weaving can be plain weave or twill, but it is particularly preferable to twill so that the thickness when the belt body 30 is formed is 3 mm or more thick and bulky.

吊りベルト３としての帯幅は、コンテナ本体２のサイズにもよるが、一般には４０〜１００ｍｍ程度とされる。 Although the band width as the suspension belt 3 depends on the size of the container main body 2, it is generally about 40 to 100 mm.

吊りベルト３には、図１、図６に示すように、第２の導電性線条体５が、長さ方向の少なくとも一部がベルト本体３０の表面（コンテナ本体２と接合される面）に露出するように、該吊りベルト３の長さ方向に沿って配設されている。 As shown in FIG. 1 and FIG. 6, the suspension belt 3 has a second conductive linear body 5 in which at least a part in the length direction is a surface of the belt body 30 (surface to be joined to the container body 2). The suspension belt 3 is disposed along the length direction so as to be exposed to the surface.

第２の導電性線条体５としては、第１の導電性線条体４と同一構成とすることができる。すなわち、アルミニウム、銅、鉄、ステンレススチール等の金属線、導電性の熱可塑性樹脂製の線条体等、一定の導電性を示すものであればよいが、ベルト本体３０の伸びに追従可能な線条体であることが好ましく、具体的には、ベルト本体３０が伸びた際に破断することがなく、ベルト本体３０の破断伸度よりも大きな破断伸度を有するものであることが好ましい。このため熱可塑性樹脂製の導電性線条体とすることが好ましい。 The second conductive filament 5 can have the same configuration as the first conductive filament 4. In other words, metal wires such as aluminum, copper, iron, stainless steel, etc., a wire body made of a conductive thermoplastic resin, etc. may be used as long as they exhibit a certain conductivity, but can follow the elongation of the belt body 30. It is preferably a striate body. Specifically, it is preferable that the belt body 30 does not break when stretched and has a breaking elongation larger than the breaking elongation of the belt body 30. For this reason, it is preferable to set it as the conductive linear body made from a thermoplastic resin.

熱可塑性樹脂製の導電性線条体としては、カーボンブラック、グラファイト、銅、真鍮、青銅、鉄、アルミニウム等の粉体を混練した熱可塑性樹脂を用いて形成された線条体とすることができる。導電性としては、表面抵抗が１０^１０Ω／□以下、好ましくは１０^８Ω／□以下であるものが用いられる。また、熱可塑性樹脂としては、布状体２０を構成する線条体２０ａ、２０ｂと同一のものを用いることができる。 The conductive linear body made of thermoplastic resin may be a linear body formed using a thermoplastic resin kneaded with powders such as carbon black, graphite, copper, brass, bronze, iron, and aluminum. it can. As the conductivity, one having a surface resistance of 10 ¹⁰ Ω / □ or less, preferably 10 ⁸ Ω / □ or less is used. Moreover, as a thermoplastic resin, the same thing as the linear bodies 20a and 20b which comprise the cloth-like body 20 can be used.

第２の導電性線条体５は、ベルト本体３０を構成する線条体３０ａと同様の一軸延伸されたフラットヤーンの他、一軸延伸されたモノフィラメントとすることもできる。第２の導電性線条体５の太さは、７５〜１００００ｄｔ程度が好ましく、複数本のフラットヤーン又はモノフィラメントを重ね合せて束ねて１本としたものを使用することが好ましい。 The second conductive filament 5 may be a monofilament stretched uniaxially in addition to a flat yarn stretched uniaxially similar to the filament 30 a constituting the belt main body 30. The thickness of the second conductive filament 5 is preferably about 75 to 10000 dt, and it is preferable to use a plurality of flat yarns or monofilaments which are bundled to form one.

ここで、吊りベルト３の長さ方向に沿って複数本（図示例では３本）の第２の導電性線条体５が並列するように配設された好ましい態様を示しているが、第２の導電性線条体５の配設本数は特に問わない。 Here, a preferred embodiment is shown in which a plurality (three in the illustrated example) of second conductive filaments 5 are arranged in parallel along the length direction of the suspension belt 3. The number of the two conductive filaments 5 disposed is not particularly limited.

第２の導電性線条体５は、織成又は編成後のベルト本体３０に後作業として縫い込むことによって配設してもよいが、ベルト本体３０を織成又は編成する際に同時に織り込むことによって、ベルト本体３０の表裏に交互に露出するように配設されることが好ましい。これにより、図６に示すように、ベルト本体３０の一方の面のみを見た場合、第２の導電性線条体５の線条体露出部５ａが吊りベルト３の長さ方向に沿って点線状に現われる。なお、図６では布状体からなるベルト本体３０を簡略化して示している。 The second conductive filament 5 may be arranged by sewing into the belt body 30 after weaving or knitting as a post work, but is woven simultaneously when weaving or knitting the belt body 30. Therefore, it is preferable that the belt main body 30 be alternately exposed on the front and back sides. Thereby, as shown in FIG. 6, when only one surface of the belt main body 30 is viewed, the linear body exposed portion 5 a of the second conductive linear body 5 extends along the length direction of the suspension belt 3. Appears as a dotted line. In FIG. 6, a belt main body 30 made of a cloth-like body is shown in a simplified manner.

ベルト本体３０の長さ方向に沿う一つの線条体露出部５ａの長さは、後述する挟み込み部材６の挟み込みが容易且つ確実となるように、５ｍｍ〜２０ｍｍ程度となるように形成することが好ましい。第２の導電性線条体５をベルト本体３０を織成する際に同時に織り込む場合は、第２の導電性線条体５の線条体３０ｂ（緯糸）に対する飛び数を適宜選択することによって、線条体露出部５ａを所望の長さとすることができる。この第２の導電性線条体５の線条体３０ｂ（緯糸）に対する飛び数は、線条体３０ａ（経糸）の飛び数よりも大きいものとされる。 The length of one linear member exposed portion 5a along the length direction of the belt body 30 may be formed to be about 5 mm to 20 mm so that the pinching member 6 described later can be easily and reliably inserted. preferable. When weaving the second conductive filament 5 at the same time as weaving the belt body 30, by appropriately selecting the number of jumps of the second conductive filament 5 to the filament 30b (weft) The linear body exposed portion 5a can be set to a desired length. The number of jumps of the second conductive filament 5 to the filament 30b (weft) is greater than the number of jumps of the filament 30a (warp).

この線条体露出部５ａは、３本の第２の導電性線条体５の並設方向で同一位置に配置されており、並設方向の３つの線条体露出部５ａを一組として、該線条体露出部５ａの組が吊りベルト３の長さ方向に沿い、該吊りベルト３の全長に亘って点線状に連続して多数配設されている。 This linear body exposed part 5a is arrange | positioned in the same position in the parallel arrangement direction of the three 2nd electroconductive linear bodies 5, and makes the three linear body exposure parts 5a of the parallel arrangement direction into 1 set. A large number of sets of the linear member exposed portions 5a are arranged along the length direction of the suspension belt 3 and continuously in dotted lines over the entire length of the suspension belt 3.

コンテナ本体２の側面に対して接合される吊りベルト３の接合端部領域３Ｂ（図１）において、第２の導電性線条体５の線条体露出部５ａの組の少なくとも一つの組には、導電性を有する樹脂製の挟み込み部材６が、並列する全ての第２の導電性線条体５の線条体露出部５ａに亘り、該第２の導電性線条体５の長さ方向と交差する方向に長く延びるように、第２の導電性線条体５とベルト本体３０との間に共通に介装されている。 In the joining end region 3B (FIG. 1) of the suspension belt 3 joined to the side surface of the container main body 2, at least one set of the set of exposed strips 5a of the second conductive strip 5 is provided. Is the length of the second conductive filament 5 over which the resin sandwiching members 6 having conductivity extend over the filament exposed portions 5a of all the second conductive filaments 5 arranged in parallel. Commonly interposed between the second conductive linear body 5 and the belt body 30 so as to extend long in a direction intersecting the direction.

挟み込み部材６は導電性を有する樹脂製帯状体である。この挟み込み部材６が、並列する線条体露出部５ａに亘ってベルト本体３０の表面との間に介装されることで、第２の導電性線条体５をベルト本体３０表面の凹凸に埋もれさせることなく、且つ、並設される各第２の導電性線条体５相互間を電気的に結合する。これにより、各第２の導電性線条体５の線からなる導電部位を帯状体からなる挟み込み部材６による面からなる導電部位とすることができる。しかも、吊りベルト３がコンテナ本体２と接合されると、並列される３本の線条体露出部５ａの全てが、コンテナ本体２と挟み込み部材６との間に挟まれて圧接される形となるため、第２の導電性線条体５と挟み込み部材６とはより密着することとなり、両者間の電気的結合をより確実なものとすることができる。 The sandwiching member 6 is an electrically conductive resin band. The sandwiching member 6 is interposed between the surface of the belt main body 30 across the parallel strip exposed portions 5a, so that the second conductive linear body 5 is made uneven on the surface of the belt main body 30. The second conductive linear bodies 5 arranged side by side are electrically coupled to each other without being buried. Thereby, the electroconductive part which consists of a line of each 2nd electroconductive linear body 5 can be made into the electroconductive part which consists of the surface by the clamping member 6 which consists of a strip | belt-shaped body. Moreover, when the suspension belt 3 is joined to the container main body 2, all of the three linear strip exposed portions 5 a arranged in parallel are sandwiched between the container main body 2 and the sandwiching member 6 and pressed. Therefore, the second conductive filament 5 and the sandwiching member 6 are more closely attached, and the electrical coupling between them can be made more reliable.

導電性を有する挟み込み部材６は、第２の導電性線条体５と同様にして、カーボンブラック、グラファイト、銅、真鍮、青銅、鉄、アルミニウム等の粉体を混練した熱可塑性樹脂を用いて形成することができる。挟み込み部材６は、このような導電性を有する熱可塑性樹脂を用いて所定厚みのフィルム状に形成されたシート状体であってもよいし、導電性を有する熱可塑性樹脂からなるフラットヤーンを経緯に使用して織成された布状体からなるシート状体であってもよい。また、布状体の片面又は両面に、導電性を有する熱可塑性樹脂からなるフィルムを積層することによって表面に導電性が付与されたものであってもよい。 The sandwiching member 6 having conductivity is made of a thermoplastic resin in which powders of carbon black, graphite, copper, brass, bronze, iron, aluminum and the like are kneaded in the same manner as the second conductive filament 5. Can be formed. The sandwiching member 6 may be a sheet-like body formed in a film shape having a predetermined thickness using such a conductive thermoplastic resin, or a flat yarn made of a conductive thermoplastic resin. It may be a sheet-like body made of a cloth-like body woven using. Moreover, the surface may be provided with conductivity by laminating a film made of a thermoplastic resin having conductivity on one or both sides of the cloth-like body.

挟み込み部材６における第２の導電性線条体５の長さ方向と直交する方向の幅Ｗ（図７）は、線条体露出部５ａとベルト本体３０との間に挿入し得るように、５ｍｍ〜２０ｍｍ程度とすることができる。 The width W (FIG. 7) in the direction orthogonal to the length direction of the second conductive linear body 5 in the sandwiching member 6 can be inserted between the linear body exposed part 5 a and the belt body 30. It can be set to about 5 mm to 20 mm.

挟み込み部材６は、第２の導電性線条体５をベルト本体３０の表面から持ち上げる方向にある程度の付勢力を及ぼし得るものであることが好ましい。例えば、図６、図７に示すように、シート状体を長さ方向に沿う折り目６ａに沿って１回折り畳んで二つ折りにした断面Ｖ字状の挟み込み部材６とし、その折り目６ａの延在方向が第２の導電性線条体５の長さ方向と交差するように介装することができる。 The sandwiching member 6 is preferably capable of exerting a certain urging force in the direction in which the second conductive linear body 5 is lifted from the surface of the belt main body 30. For example, as shown in FIGS. 6 and 7, the sheet-like body is folded once along a fold 6a along the length direction to be folded in half, and the fold 6a is extended. It can be interposed so that the direction intersects the length direction of the second conductive filament 5.

このような挟み込み部材６は、樹脂シート自体の弾性復元力によって折り目６ａが開く方向に付勢力が働くので、挟み込み部材６が介装された第２の導電性線条体５の線条体露出部５ａは、図７に示すようにベルト本体３０の表面から高く突出するように持ち上げられ、ベルト本体３０表面の凹凸に埋もれてしまうことがないので、後述するように、この吊りベルト３がコンテナ本体２に接合された際に、コンテナ本体２側の第１の導電性線条体４と確実に接触させることができ、両者の確実な電気的な結合状態を得ることができるようになる。 Such a sandwiching member 6 exerts a biasing force in the direction in which the crease 6a is opened by the elastic restoring force of the resin sheet itself, so that the strips of the second conductive filament 5 in which the sandwiching member 6 is interposed are exposed. As shown in FIG. 7, the portion 5a is lifted so as to protrude highly from the surface of the belt main body 30, and is not buried in the irregularities on the surface of the belt main body 30. When joined to the main body 2, the first conductive linear body 4 on the container main body 2 side can be reliably brought into contact with each other, and a reliable electrical coupling state between them can be obtained.

この第２の導電性線条体５の線条体露出部５ａの突出高さｈは、コンテナ本体２側の第１の導電性線条体４との確実な電気的結合を行う観点から、コンテナ本体２への接合前の状態で、ベルト本体３０の最表面から１ｍｍ〜５ｍｍ程度が好ましい。 From the viewpoint of performing reliable electrical coupling with the first conductive filament 4 on the container body 2 side, the protruding height h of the filament exposed portion 5a of the second conductive filament 5 is as follows. About 1 mm to 5 mm from the outermost surface of the belt main body 30 in the state before joining to the container main body 2 is preferable.

また、挟み込み部材６の長さ（吊りベルト３の幅方向の長さ）は、少なくとも３本の第２の導電性線条体５に亘る長さであればよいが、図６に示すように、ベルト本体３０の幅方向よりも長尺に形成して側方にはみ出すように形成してもよい。これにより、吊りベルト３をコンテナ本体２に接合する際、挟み込み部材６によって線条体露出部５ａが持ち上げられている部位を外側から容易に確認することができ、コンテナ本体２側の第１の導電性線条体４、特にコンテナ本体２の横方向に沿って配設されている第１の導電性線条体４との位置合わせが容易となるため、縫製時に位置合わせを行う場合であっても、作業性の低下を招くおそれはない。 Further, the length of the sandwiching member 6 (the length in the width direction of the suspension belt 3) may be a length extending over at least three second conductive filaments 5, as shown in FIG. The belt main body 30 may be formed longer than the width direction so as to protrude to the side. Thereby, when joining the suspending belt 3 to the container main body 2, it is possible to easily confirm from the outside the portion where the striated body exposed portion 5 a is lifted by the sandwiching member 6, and the first on the container main body 2 side. In this case, alignment with the conductive linear body 4, particularly the first conductive linear body 4 disposed along the lateral direction of the container body 2, is easy. However, there is no risk of reducing workability.

挟み込み部材６をはみ出させる場合は、図示するようにベルト本体３０の両側にはみ出させるものに限らず、いずれか一方の側のみにはみ出させるようにしても同様の効果を得ることができる。 When the sandwiching member 6 is protruded, the same effect can be obtained not only by protruding from both sides of the belt main body 30 as shown in the figure but also by protruding only from one side.

挟み込み部材６を線条体露出部５ａとベルト本体３０との間に介装させる手段としては、ベルト本体３０の片面の所定位置に予め挟み込み部材６を配置しておき、第２の導電性線条体５が挟み込み部材６の上を跨ぐように織り込み又は縫い込みするようにしてもよいし、第２の導電性線条体５が配設された後のベルト本体３０の一組の線条体露出部５ａに亘って、後作業として横方向から挿入するようにしてもよい。 As a means for interposing the pinching member 6 between the linear member exposed portion 5a and the belt main body 30, the pinching member 6 is arranged in advance at a predetermined position on one side of the belt main body 30, and the second conductive wire The strip 5 may be woven or sewn so as to straddle the sandwiching member 6, or a set of strips of the belt main body 30 after the second conductive filament 5 is disposed. You may make it insert from the horizontal direction as a post-operation over the body exposure part 5a.

このようにして形成された吊りベルト３は、図８、図９に示すように、両接合端部領域３Ｂを、挟み込み部材６が介装されている面がコンテナ本体２の側面に配置されるようにして所定部位に添設した後、縫合糸７によって縫合される。ここでは、コンテナ本体２側の横方向（図示左右方向）に延びる第１の導電性線条体４が、縦方向（図示上下方向）に所定間隔で多数配設されており、吊りベルト３は、挟み込み部材６が横方向に延びるいずれかの第１の導電性線条体４の位置に重なり合うように接合されている。この挟み込み部材６も横方向に延びていると共にその両端は吊りベルト３の幅よりも突出しているので、この位置合わせは極めて容易である。 In the suspension belt 3 formed in this way, as shown in FIGS. 8 and 9, both joint end regions 3 </ b> B are disposed on the side surface of the container body 2 with the surface on which the sandwiching member 6 is interposed. In this manner, after being attached to a predetermined site, the suture thread 7 is sutured. Here, a large number of first conductive filaments 4 extending in the lateral direction (left-right direction in the figure) on the container body 2 side are arranged at predetermined intervals in the vertical direction (up-down direction in the figure). The sandwiching member 6 is joined so as to overlap with the position of any of the first conductive filaments 4 extending in the lateral direction. Since this sandwiching member 6 also extends in the lateral direction and both ends thereof protrude beyond the width of the suspension belt 3, this positioning is extremely easy.

この接合時、挟み込み部材６によって持ち上げられた第２の導電性線条体５の線条体露出部５ａは、コンテナ本体２に向けて大きく突出する形となるため、ベルト本体３０が肉厚で嵩高に形成されていても、当該線条体露出部５ａがコンテナ本体２の第１の導電性線条体４に対して大きく突出して接触することができる。 At the time of this joining, the linear body exposed portion 5a of the second conductive linear body 5 lifted by the sandwiching member 6 projects greatly toward the container body 2, so that the belt body 30 is thick. Even if it is formed bulky, the said linear body exposed part 5a can protrude largely with respect to the 1st electroconductive linear body 4 of the container main body 2, and can contact it.

そして、この状態で、コンテナ本体２と吊りベルト３とは、縫合糸７によって縫合される。この縫合糸７による縫合は、図８では縦方向、横方向及び斜め方向に行うようにしているが、少なくとも挟み込み部材６とコンテナ本体２側の第１の導電性線条体４との重合部を通過し得るように縫合される。これにより、第１の導電性部材４、挿み込み部材６及び第２の導電性部材５の線条体露出部５ａが縫合糸７によって一体に締め付けられて緊密に密着するようになり、これらの間の電気的結合は確実なものとなる。 In this state, the container body 2 and the suspension belt 3 are sutured with the suture thread 7. In FIG. 8, the stitching by the suture thread 7 is performed in the vertical direction, the horizontal direction, and the diagonal direction. However, at least the overlapping portion of the sandwiching member 6 and the first conductive linear body 4 on the container body 2 side. To be able to pass through. As a result, the linear member exposed portions 5a of the first conductive member 4, the insertion member 6, and the second conductive member 5 are tightened together by the suture thread 7 so as to be in close contact with each other. The electrical coupling between is ensured.

挟み込み部材６の幅Ｗは、図８に示すように、線条体露出部５ａとベルト本体３０との間に介装された状態で、縫合糸７の縫製ピッチＰよりも大きいことが好ましい。これにより、縫合糸７によって挟み込み部材６を縦断するように縦方向に縫合しても、縫合糸７は必ず挟み込み部材６の部位を貫通することになり、導電性の挟み込み部材６をコンテナ本体２の表面に確実且つ緊密に密着させることができる。 As shown in FIG. 8, the width W of the sandwiching member 6 is preferably larger than the sewing pitch P of the suture thread 7 when it is interposed between the striate body exposed portion 5 a and the belt body 30. Accordingly, even if the suture member 7 is sutured in the vertical direction so as to cut the sandwiching member 6 longitudinally, the suture thread 7 always passes through the portion of the sandwiching member 6, and the conductive sandwiching member 6 is attached to the container body 2. Can be reliably and closely adhered to the surface.

なお、コンテナ本体２と吊りベルト３とは、更に、吊りベルト３の幅方向に亘って挟み込み部材６の長さ方向に沿うように、縫合糸７によって該挟み込み部材６の部位に集中的に縫合を行うようにして、電気的結合の更なる確実性を図るようにしてもよい。 The container body 2 and the suspension belt 3 are further sewn intensively to the portion of the sandwiching member 6 with the suture thread 7 so as to follow the length direction of the sandwiching member 6 over the width direction of the suspension belt 3. In this case, the electrical coupling may be further ensured.

挟み込み部材６は、第２の導電性線条体５の線条体露出部５ａに対して同様の付勢力を及ぼし得るものであれば、断面Ｖ字状に折り畳むものに限らず、例えば図１０（ａ）に示すように、２箇所の折り目６ａ、６ｂを有する断面Ｚ字状としてもよく、更に図１０（ｂ）に示すように、３箇所の折り目６ａ、６ｂ、６ｃを有する断面Ｗ字状としてもよい。更に４箇所以上の蛇腹状に折り畳むようにしてもよいことはもちろんである。 The sandwiching member 6 is not limited to one that is folded in a V-shaped cross section as long as it can exert the same urging force on the linear member exposed portion 5a of the second conductive linear member 5, for example, FIG. As shown to (a), it is good also as a cross-sectional Z shape which has two folds 6a and 6b, and also as shown in FIG.10 (b), the cross-section W shape which has three folds 6a, 6b, and 6c. It is good also as a shape. Of course, it may be folded into four or more bellows.

また、挟み込み部材６は、図１０（ｃ）に示すように、断面Ｏ字状となる中空円筒形状の管状体によって形成してもよい。このような管状体からなる挟み込み部材６であっても、線条体露出部５ａとベルト本体３０との間に介装されると、両者間に押し潰されて帯状の挟み込み部材６となり、それが管状に戻ろうとする復元力によって、線条体露出部５ａを持ち上げるように付勢力を付与することができる。 Further, as shown in FIG. 10C, the sandwiching member 6 may be formed of a hollow cylindrical tubular body having an O-shaped cross section. Even if it is the pinching member 6 which consists of such a tubular body, if it is interposed between the linear body exposed part 5a and the belt main body 30, it will be crushed between both and it will become the strip | belt-shaped pinching member 6, The urging force can be applied so as to lift the striatum body exposed portion 5a by the restoring force of returning to the tubular shape.

挟み込み部材６を折り畳みによって形成する場合、図１１（ａ）に示すように、第２の導電性線条体５の長さ方向に沿う折り目６ｄによって挟み込み部材６自体の長さ方向に折り畳むようにしてもよい。折り畳み回数は複数回であってもよく、例えば図１１（ｂ）に示すように、二つの折り目６ｄ、６ｅを形成したものとすることもできる。 When the sandwiching member 6 is formed by folding, as shown in FIG. 11A, the sandwiching member 6 is folded in the length direction of the sandwiching member 6 itself by a crease 6d along the length direction of the second conductive filament 5. May be. The number of times of folding may be a plurality of times. For example, as shown in FIG. 11B, two folds 6d and 6e may be formed.

更に、挟み込み部材６は、図１２に示すように、吊りベルト３においてコンテナ本体２と接合される接合端部領域３Ｂ内に、ベルト本体３０に配設された第２の導電性線条体５の長さ方向に沿って間隔をおいて複数個所の線条体露出部５ａを有する場合、該複数個所の線条体露出部５ａのそれぞれとベルト本体３０との間に個別に介装してもよい。これにより、コンテナ本体２側の第１の導電性線条体４との電気的結合をより一層確実なものとすることもできる。特に、図１３に示すように、複数の挟み込み部材６の間隔を、コンテナ本体２の横方向に延びる第１の導電性線条体４の縦方向の間隔と等間隔となるように配設すると、各挟み込み部材６を第１の導電性線条体４とそれぞれ重なり合うように接合することができ、更に電気的結合の確実性を増すことができる。 Further, as shown in FIG. 12, the sandwiching member 6 includes a second conductive filament 5 disposed on the belt main body 30 in a joining end region 3 </ b> B joined to the container main body 2 in the suspension belt 3. When there are a plurality of striated body exposed portions 5a at intervals along the length direction, the striated body exposed portions 5a at the plurality of locations are individually interposed between the belt main body 30 and the belt body 30. Also good. Thereby, electrical connection with the 1st conductive filament 4 by the side of container main part 2 can be made still more reliable. In particular, as shown in FIG. 13, when the intervals between the plurality of sandwiching members 6 are arranged so as to be equal to the interval in the vertical direction of the first conductive filaments 4 extending in the lateral direction of the container body 2. In addition, each sandwiching member 6 can be joined so as to overlap each of the first conductive filaments 4, and the reliability of electrical coupling can be further increased.

以上の説明では、コンテナ本体２と吊りベルト３とを直に接合させて縫合するようにしたが、両者間に更に導電性シート状体を挟むようにしてもよい。 In the above description, the container body 2 and the suspension belt 3 are directly joined and stitched, but a conductive sheet-like body may be further sandwiched between them.

図１４は、導電性シート状体８を更に介装してコンテナ本体２と吊りベルト３とを縫合した状態を示している。 FIG. 14 shows a state in which the container main body 2 and the suspension belt 3 are stitched with the conductive sheet-like body 8 interposed therebetween.

導電性シート状体８は、樹脂製の導電性線条体を用いて形成された柔軟なシート状体であり、第１の導電性線条体４と同様の導電性の熱可塑性樹脂製の線条体を用いて形成された織布、編布又は不織布からなる布状体の他、導電性樹脂フィルムを用いて形成されたシート状体を用いることもできる。特に、コンテナ本体２や吊りベルト３との追従性が良好な布状体からなる導電性シート状体が好ましい。 The conductive sheet-like body 8 is a flexible sheet-like body formed using a resin-made conductive linear body, and is made of the same conductive thermoplastic resin as the first conductive linear body 4. In addition to a cloth-like body made of a woven fabric, a knitted fabric or a non-woven fabric formed using a linear body, a sheet-like body formed using a conductive resin film can also be used. In particular, a conductive sheet-like body made of a cloth-like body having good followability with the container body 2 and the suspension belt 3 is preferable.

導電性シート状体８は、吊りベルト３のコンテナ本体２と接合される接合端部領域３Ｂの全面と接するように介装することもできるが、図１４に示すように、少なくとも挟み込み部材６とコンテナ本体２の第１の導電性線条体４との双方にそれぞれ重なり合うように介装すればよい。少なくとも挟み込み部材６と接触していれば、吊りベルト３に配設されている全ての第２の導電性線条体５との電気的結合を図ることができるためである。 The conductive sheet-like body 8 can be interposed so as to be in contact with the entire surface of the joining end region 3B joined to the container body 2 of the suspension belt 3, but as shown in FIG. 14, at least the sandwiching member 6 and What is necessary is just to interpose so that it may each overlap with both the 1st electroconductive linear bodies 4 of the container main body 2. FIG. This is because as long as it is in contact with at least the sandwiching member 6, it is possible to achieve electrical connection with all the second conductive filaments 5 arranged on the suspension belt 3.

図１４では、吊りベルト３の両側部に沿うように配設された２枚の帯状の導電性シート状体８を、コンテナ本体２の側面を縦方向に延びる第１の導電性線条体４に沿うように介装し、縫合糸７によって縫合した例を示している。縫合糸７は、縦方向に延びる第１の導電性線条体４の近傍、好ましくは該第１の導電性線条体４の真上に沿い、且つ、導電性シート状体８の長さ方向に沿うように縫製されている。 In FIG. 14, two strip-like conductive sheet-like bodies 8 arranged along both side portions of the suspension belt 3 are used as the first conductive linear bodies 4 that extend in the longitudinal direction on the side surface of the container body 2. An example is shown in which the needle is inserted along the line and sutured by the suture thread 7. The suture thread 7 is located in the vicinity of the first conductive filament 4 extending in the longitudinal direction, preferably directly above the first conductive filament 4 and the length of the conductive sheet-like element 8. Sewn along the direction.

導電性シート状体８は、コンテナ本体２と同様に柔軟性を有するため、コンテナ本体２の表面の撓みに容易に追従し、第１の導電性線条体４との密着を良好にすると同時に、挟み込み部材６とも良好に密着し、縫合糸７によって緊密に締め付けられて第１の導電性線条体４と第２の導電性線条体５との間の電気的結合を確実なものとする。 Since the conductive sheet-like body 8 has flexibility similar to the container main body 2, it easily follows the deflection of the surface of the container main body 2 and at the same time improves the close contact with the first conductive linear body 4. The sandwiching member 6 is also in good close contact with each other and is tightly tightened by the suture thread 7 to ensure the electrical coupling between the first conductive filament 4 and the second conductive filament 5. To do.

しかも、このように導電性シート状体８を介装する場合、この導電性シート状体８を介してコンテナ本体２の第１の導電性線条体４と吊りベルト３の第２の導電性線条体５との電気的結合を行うので、必ずしも挟み込み部材６がコンテナ本体２の第１の導電性線条体４と重なり合っている必要はない。このため、吊りベルト３の接合作業において位置決めを行う手間を省くことができ、作業性が向上する。 Moreover, when the conductive sheet-like body 8 is interposed in this way, the first conductive linear body 4 of the container body 2 and the second conductive property of the suspension belt 3 are interposed via the conductive sheet-like body 8. Since the electrical connection with the linear body 5 is performed, the sandwiching member 6 does not necessarily have to overlap the first conductive linear body 4 of the container main body 2. For this reason, the trouble of positioning in the joining operation | work of the suspension belt 3 can be saved, and workability | operativity improves.

特に、図１４に示すように、導電性シート状体８を挟みこみ部材６と直交するように縦方向に長く延びるように介装すると、コンテナ本体２の縦方向の長い距離に亘って挟み込み部材６との電気的結合を行うことができる。これは、例えばコンテナ本体２の第１の導電性線条体４が、図８に示したように横方向に延び、それが縦方向に所定間隔をおいて並設されるものである場合であっても、挟み込み部材６の位置合わせを行う必要なく、該挟み込み部材６を介して第２の導電性線条体５と第１の導電性線条体４との電気的結合を可能にする。 In particular, as shown in FIG. 14, when the conductive sheet 8 is interposed so as to extend in the longitudinal direction so as to be orthogonal to the sandwiching member 6, the sandwiching member over a long distance in the longitudinal direction of the container body 2. 6 can be electrically coupled. This is the case, for example, when the first conductive filaments 4 of the container body 2 extend in the horizontal direction as shown in FIG. 8 and are arranged in parallel in the vertical direction at a predetermined interval. Even if it exists, the electrical connection of the 2nd electroconductive wire 5 and the 1st electroconductive wire 4 is enabled via this pinching member 6, without having to align position of pinch member 6 .

なお、導電性シート状体８は、更に横方向に延びるように介装してもよいことはもちろんである。例えば図１５に示すように、挟み込み部材６に沿って該挟み込み部材６と重なり合って密着するように横方向に延びる導電性シート状体８Ａを介装し、更に、この導電性シート状体８Ａとコンテナ本体２との間に、縦方向に延びる第１の導電性線条体４に沿うように縦方向に延びる導電性シート状体８Ｂを介装し、これらを一体に縫合糸７によって縫合することもできる。これによれば、比較的柔軟な導電性シート状体８Ａ、８Ｂ同士の良好な密着によって電気的結合を図ることができるので、より確実な電気的結合を行うことができる。 Needless to say, the conductive sheet-like body 8 may be further interposed so as to extend in the lateral direction. For example, as shown in FIG. 15, a conductive sheet-like body 8A extending in the lateral direction so as to overlap and be in close contact with the sandwiching member 6 along the sandwiching member 6 is further interposed. A conductive sheet-like body 8B extending in the vertical direction is provided between the container main body 2 and the first conductive linear body 4 extending in the vertical direction, and these are integrally sutured with a suture thread 7. You can also. According to this, since electrical coupling can be achieved by good adhesion between the relatively flexible conductive sheet-like bodies 8A and 8B, more reliable electrical coupling can be performed.

このようにしてコンテナ本体２に適宜数の吊りベルト３が接合されることによってフレキシブルコンテナ１が完成する。完成したフレキシブルコンテナ１は、収容物の充填又は排出の際等に、吊りベルト３にフック等の吊り上げ治具（図示せず）を引っ掛けた状態で収容物の充填、排出が行われる。この際、コンテナ本体２及び吊りベルト３に帯電した静電気を、コンテナ本体２の適宜の部位に設けられた導電性シート状体等からなる除電部９（図１参照）を介して逃がし、フレキシブルコンテナ１全体の帯電を防止することができ、高い帯電防止性能を得ることができる。 Thus, the flexible container 1 is completed by joining an appropriate number of suspension belts 3 to the container body 2. The completed flexible container 1 is filled and discharged with the suspended belt 3 hooked with a lifting jig (not shown) such as a hook when filling or discharging the stored item. At this time, static electricity charged in the container main body 2 and the suspension belt 3 is released through a static eliminating portion 9 (see FIG. 1) made of a conductive sheet or the like provided in an appropriate portion of the container main body 2 to thereby form a flexible container. 1 can be prevented from being charged as a whole, and high antistatic performance can be obtained.
