Description
この発明は、二枚重ねの合成樹脂フィルムの周囲を溶着シールするだけで、他の部品をまったく用いることなく安価に製造することができる袋に関し、とくに、飲料水を注入して運搬したり保管するという用途に主眼をおいて開発した合成樹脂フィルム製の袋を提供するものである。 The present invention relates to a bag that can be manufactured at low cost without using any other parts by simply welding and sealing the periphery of a two-layer synthetic resin film, and in particular, injecting and transporting and storing drinking water. It is to provide a bag made of synthetic resin film developed with a focus on applications.
たとえば、災害時に給水車などから供給される飲料水を各自で運搬するような状況を想定し、水を注入して運搬したり保管するのに適した合成樹脂フィルム製の袋が各種製品化されている。下記の文献にはそのような袋の具体的な構成が詳しく記載されている。 For example, assuming a situation where each person carries drinking water supplied from a water truck at the time of a disaster, various plastic resin bags suitable for injecting water for transportation and storage have been commercialized. ing. The following document describes in detail the specific construction of such a bag.

上記のような用途にあわせた合成樹脂フィルム製の袋（ウォーターバッグとも記す）の従来のものはいずれも、水を注入したあとで注水口を塞ぐために、蓋や弁を用いた構成を採用している。そのために手数のかかる製造工程にならざるを得ず、蓋や弁などの部品コストに加えて製造コストも大きかった。 All of the conventional synthetic resin film bags (also referred to as water bags) that match the above-mentioned uses adopt a configuration that uses a lid and a valve to close the inlet after water has been injected. ing. For this reason, the manufacturing process is tedious, and the manufacturing cost is high in addition to the cost of parts such as lids and valves.
特許第４８８５３１５号公報には、出願人が先に開発した「逆止弁作用のある気道を形成した合成樹脂フィルム製の風船体」について詳細に開示されている。これは、二枚重ねの合成樹脂フィルムの周囲を溶着シールするだけで、他の多くの類似製品に見られるような弁部品を用いることなく安価に製造することができ、空気を注入して膨らませたり、排気してペチャンコにすることができる風船様の袋である。野球場で観客が用いる座布団などとして製品化されてる。 Japanese Patent No. 4885315 discloses in detail the "balloon body made of a synthetic resin film that forms an airway having a check valve action" that was previously developed by the applicant. It can be manufactured at low cost without using valve parts like those found in many other similar products, just by welding and sealing the periphery of the two-layer synthetic resin film, inflating by injecting air, A balloon-like bag that can be evacuated into a pecan. It is commercialized as a cushion used by spectators at baseball fields.
本願の発明者は、上記の特許製品と同様な原理で実用的なウォーターバッグを実現できれば、従来より格段に安上がりになると考え、上記特許技術を微調整しながら試作実験を繰り返し行ったところ、５〜１０リットルほどの大容量のウォーターバッグでは実用的な止水性能・封止性能を実現することができなかった。 The inventor of the present application thinks that if a practical water bag can be realized on the same principle as the above-mentioned patented product, it will be much cheaper than before, and repeated trial experiments while finely adjusting the above-mentioned patented technology, 5 A water bag with a large capacity of about 10 liters could not achieve practical water stopping performance and sealing performance.
発明者が目標としたのは、長方形の偏平な袋からなる１０リットル程度の容量のウォーターバッグであり、満水状態にした座布団のような袋を横に寝かしても一方の短辺に設けた注水口から漏水することがなく、満水の袋に数十キロ程度の荷重をかけても漏水も破損もしないことである。 The inventor's goal was a water bag with a capacity of about 10 liters consisting of a rectangular flat bag, and a bag like a cushion that was full of water was placed on one short side even when lying down sideways. There is no water leakage from the water mouth, and even if a load of several tens of kilometers is applied to a full water bag, it will not leak or break.
上記の目標を達成すべく、上記特許技術の溶着シール線のパターンから離れて、あらたに１００種類以上のパターンを試作しては実験を繰り返した結果、以下に説明するこの発明を創作するに到った。 In order to achieve the above-mentioned target, apart from the welded seal line pattern of the above-mentioned patented technology, 100 or more types of new patterns were prototyped and the experiment was repeated. As a result, the present invention described below was created. It was.

図１はこの発明に係る約１０リットル容量の袋（ウォーターバッグ）を示し、実物の寸法を付記している。図２はこの袋の核心をなす上辺部分の拡大図である。この袋の素材は厚さ２００μｍのポリエチレンフィルムである。長方形の二枚重ねフィルムは筒状のインフレーション成形品であり、二枚重ねフィルムの右辺と左辺はもともと一体に繋がっている。二枚重ねフィルムの下辺部分は溶着形成された図１に示す下辺シール線１により水密に一体化されている。二枚重ねフィルムの上辺部分には、この発明の核心をなす特殊パターンの溶着シール線が形成されている。以下このパターンについて詳述する。 FIG. 1 shows a bag (water bag) having a capacity of about 10 liters according to the present invention, and the actual dimensions are added. FIG. 2 is an enlarged view of the upper side portion forming the core of the bag. The material of this bag is a polyethylene film having a thickness of 200 μm. The rectangular double-layer film is a tubular inflation molded product, and the right side and the left side of the double-layer film are originally connected together. The lower side portion of the two-ply film is integrated in a watertight manner by a lower side seal line 1 shown in FIG. 1 formed by welding. On the upper side of the two-ply film, a weld seal line having a special pattern that forms the core of the present invention is formed. Hereinafter, this pattern will be described in detail.
＝＝＝上辺部分の溶着シール線のパターン＝＝＝
袋空間の上辺側を区画する溶着シール線は、その中央において途切れて右上辺シール線２と左上辺シール線３に分かれており、右上辺シール線２の先端Ａと左上辺シール線３の先端Ｂとは寸法Ｌ＝５０ｍｍだけ隔たっている。
=== Pattern of welding seal line in upper side portion ===
The welding seal line that divides the upper side of the bag space is interrupted at the center and is divided into an upper right side seal line 2 and an upper left side seal line 3, and an end A of the upper right side seal line 2 and an end of the upper left side seal line 3. It is separated from B by a dimension L = 50 mm.
右上辺シール線２の先端Ａには、溶着シール線により形成された、右外テーパー線４、右内テーパー線５、右補強縦線６の各一端が接続している。また、左上辺シール線３の先端Ｂには、溶着シール線により形成された、左外テーパー線７、左内テーパー線８、左補強縦線９の各一端が接続している。 One end of each of a right outer tapered line 4, a right inner tapered line 5, and a right reinforcing vertical line 6 formed by a welding seal line is connected to the tip A of the upper right side seal line 2. Further, one end of a left outer taper line 7, a left inner taper line 8, and a left reinforcing vertical line 9 formed by a welding seal line is connected to the tip B of the upper left side seal line 3.
図１および図２から明らかなように、右上辺シール線２・右外テーパー線４・右内テーパー線５・右補強縦線６を含む右側のパターンと、左上辺シール線３・左外テーパー線７・左内テーパー線８・左補強縦線９を含む左側のパターンは左右対称になっている。 As is apparent from FIGS. 1 and 2, the right side pattern including the upper right side seal line 2, the right outer taper line 4, the right inner taper line 5, and the right reinforcing vertical line 6, and the upper left side seal line 3 and the left outer taper. The pattern on the left side including the line 7, the left inner taper line 8, and the left reinforcing vertical line 9 is symmetric.
先端Ａに繋がる右外テーパー線４と先端Ｂに繋がる左外テーパー線７は前記フィルムの上縁部分まで延びており、左右の外テーパー線４と７の間隔は、最下部が前記寸法Ｌであり、上方に向かって徐々に大きくなっている。 A right outer taper line 4 connected to the tip A and a left outer taper line 7 connected to the tip B extend to the upper edge portion of the film. The distance between the left and right outer taper lines 4 and 7 is the dimension L at the bottom. Yes, gradually increasing upward.
先端Ａに繋がる右内テーパー線５と先端Ｂに繋がる左内テーパー線８は、右上辺シール線２・左上辺シール線３から寸法Ｍ＝８０ｍｍだけ隔たった下方まで延びており、左右の内テーパー線５と８の間隔は、最上部が前記寸法Ｌであり、下方に向かって徐々に小さくなり最下部では寸法Ｎ＝２３ｍｍである。 The right inner taper line 5 connected to the tip A and the left inner taper line 8 connected to the tip B extend to the lower side separated by a dimension M = 80 mm from the seal line 2 on the upper right side and the seal line 3 on the upper left side. The distance between the lines 5 and 8 is the dimension L at the top and gradually decreases downward, and the dimension N = 23 mm at the bottom.
先端Ａに繋がる右補強縦線６と先端Ｂに繋がる左補強縦線９は、右上辺シール線２・左上辺シール線３から前記寸法Ｍだけ隔たった下方まで延びており、右内テーパー線５と右補強縦線６との間隔は下方に向かって徐々に広がり（下端の間隔は４１．５ｍｍ）、同様に、左内テーパー線８と左補強縦線９との間隔は下方に向かって徐々に広がっている（下端の間隔は４１．５ｍｍ）。 The right reinforcing vertical line 6 connected to the tip A and the left reinforcing vertical line 9 connected to the tip B extend to the lower side separated from the upper right seal line 2 and the upper left seal line 3 by the dimension M, and the right inner taper line 5. And the right reinforcing vertical line 6 gradually expand downward (the lower end spacing is 41.5 mm). Similarly, the distance between the left inner tapered line 8 and the left reinforcing vertical line 9 gradually decreases downward. (The interval between the lower ends is 41.5 mm).
右内テーパー線５の下端と右補強縦線６の下端は溶着シール線により形成された右補強横線１０の両端と接続されており、左内テーパー線８の下端と左補強縦線９の下端は溶着シール線により形成された左補強横線１１の両端と接続されている。 The lower end of the right inner taper line 5 and the lower end of the right reinforcing vertical line 6 are connected to both ends of the right reinforcing horizontal line 10 formed by the welding seal line, and the lower end of the left inner tapered line 8 and the lower end of the left reinforcing vertical line 9 are connected. Is connected to both ends of the left reinforcing horizontal line 11 formed by a welding seal line.
左右の内テーパー線５・８はその中間部分でくの字型にわずかに折れ曲がっており、この折れ曲がりにより左右の内テーパー線５と８の間隔がこれらが直線である場合より大きくなっており、ちょうど中間の折れ曲がり点での左右の間隔は４０ｍｍである。 The inner taper lines 5 and 8 on the left and right are slightly bent into a dogleg shape at the middle part thereof, and the distance between the inner taper lines 5 and 8 on the left and right is larger than the case where these are straight lines. The distance between the right and left at the middle bending point is 40 mm.
上記した折れ曲がりを無視すると、右側の内テーパー線５と補強縦線６と補強横線１０は、底辺４１．５ｍｍで高さ８０ｍｍの三角形の閉じた領域Ｃを形成しており、この三角領域Ｃの二枚重ねフィルム間には水や空気が出入りすることはなく、二枚重ねフィルムは密着した状態に保たれる。左右対称パターンの補強横線１１により、左側にも同様な閉じた三角領域Ｄが形成されている。 If the above bending is ignored, the inner taper line 5, the reinforcing vertical line 6, and the reinforcing horizontal line 10 on the right side form a closed region C of a triangle having a base of 41.5 mm and a height of 80 mm. Water and air do not enter and exit between the two stacked films, and the two stacked films are kept in close contact with each other. A similar closed triangular region D is formed on the left side by the reinforcing horizontal lines 11 having a symmetrical pattern.
右補強縦線６と右補強横線１０の接続点には溶着シール線により形成された４５ｍｍほどの右突堤線１２の基端が接続されており、右突堤線１２の先端側は右補強横線１０のほぼ延長方向ですこし上向きに傾斜して延び、右突堤線１２の先端と右上辺シール線２の間隔は６５ｍｍになっている。左右対称パターンにより、左側にも同様な左突堤線１３が形成されている。 A base end of a right jetty line 12 of about 45 mm formed by a welding seal line is connected to a connection point between the right reinforcing vertical line 6 and the right reinforcing horizontal line 10, and the distal end side of the right jetty line 12 is the right reinforcing horizontal line 10. The extension of the right jetty line 12 and the upper right side seal line 2 is 65 mm. A similar left jetty line 13 is also formed on the left side due to the symmetrical pattern.
また、左右の上辺シール線２・３の上部であって左右の外テーパー線４・７の外側部分の二枚重ねフィルムに持ち手となる、左右２個ずつ合計４個の丸穴１４が形成されている。この丸穴１４の周囲には補強用の円形の溶着シール線１５が形成されている。さらに、二枚重ねフィルムの上縁直下であって左右の外テーパー線４・７の外側部分に補強用の溶着シール線１６が形成されている。この４個の丸穴１４による作用効果はあとで説明する。なお以上の溶着シール線の線幅は約３ｍｍである。 In addition, a total of four round holes 14 are formed on each of the left and right outer taper lines 4 and 7 on the outer side of the left and right outer taper lines 4 and 7 to form a handle on the two-layer film. Yes. A circular welding seal line 15 for reinforcement is formed around the round hole 14. Further, a welding seal line 16 for reinforcement is formed immediately below the upper edge of the double-ply film and on the outer portions of the left and right outer taper wires 4 and 7. The effects of the four round holes 14 will be described later. The line width of the above welded seal line is about 3 mm.
＝＝＝袋に水を入れる＝＝＝
以上の説明から明らかなように、二枚重ねフィルムによる袋空間は、左右の外テーパー線４と７の間隔部分および内テーパー線５と８の間隔部分を通じてのみ外気と繋がる構成になっている。この間隔部分を通水路と呼ぶことにする。
=== Pour water into the bag ===
As apparent from the above description, the bag space formed by the two-ply film is configured to be connected to the outside air only through the gap between the left and right outer taper lines 4 and 7 and the gap between the inner taper lines 5 and 8. This interval portion is called a water channel.
袋に水を入れるには水道や給水車の蛇口に繋がれた給水ホースを用いる。給水ホースの径は、左右の内テーパー線５と８の下端部分の二枚重ねフィルムにより形成される円形に合致する寸法がよい。通水路の上縁の二枚重ねフィルムを手指を使って引き剥がし、その間に給水ホースを差し込み、内テーパー線５と８の下端部分に到達させる。 To fill the bag with water, use a water supply hose connected to the faucet of a water supply or water truck. The diameter of the water supply hose should have a dimension that matches the circular shape formed by the two-layered film on the lower end portions of the left and right inner taper lines 5 and 8. The two-layer film on the upper edge of the water passage is peeled off with fingers, and a water supply hose is inserted between them to reach the lower end portions of the inner taper lines 5 and 8.
その状態で給水ホースに水を送り込むと袋空間の内部に水が入り、袋空間を形成している二枚重ねフィルムが剥がれて間隔が広がり、水を充填した袋空間が膨らんでくる。この実施例の袋には約１０リットルの水が入る。袋空間がほぼ満水になったならば、給水ホースを通水路から抜きとる。そうすると、以下に詳述するように、通水路部分が左右から圧迫され、通水路部分の二枚重ねフィルムが密着状態で尾根状に褶曲して水を漏らすことがない。 When water is fed into the water supply hose in this state, water enters the inside of the bag space, the two-layer film forming the bag space is peeled off, the interval is widened, and the bag space filled with water swells. The bag of this example contains about 10 liters of water. When the bag space is almost full, remove the water supply hose from the waterway. Then, as will be described in detail below, the water passage portion is pressed from the left and right, and the double-layer film of the water passage portion does not bend into a ridge shape in close contact and leak water.
＝＝＝水は漏れない＝＝＝
図３の写真は、図１の袋に約１０リットルの水を入れ、水平な台の上にこの満水袋を横にして置いた状態を撮影したものである。図４の写真は、図３の状態の満水袋の前記通水路周辺をクローズアップ撮影したものである。
=== Water does not leak ===
The photograph in FIG. 3 is a photograph of a state in which about 10 liters of water is put in the bag of FIG. 1 and the full bag is placed on a horizontal table. The photograph of FIG. 4 is a close-up photograph of the vicinity of the water passage of the full water bag in the state of FIG.
２つの写真からわかるように、通水路部分は、二枚重ねフィルムが密着している左右の前記三角領域ＣおよびＤと、その外側に存在する水で膨らんだ領域によって左右から圧迫され、とくに、三角領域Ｃ・Ｄの頂点であり上辺シール線２・３の先端であるＡ点およびＢ点により局部的な大きな圧迫力がかかるとともに、その圧迫力が通水路の奧に向けて徐々に弱まる状態がつくり出される。 As can be seen from the two photographs, the water passage portion is pressed from the left and right by the left and right triangular areas C and D where the two-layer film is in close contact, and the area swollen by water existing outside thereof, A large compressive force is applied locally by points A and B, which are the apexes of C and D, and the tips of the upper seal lines 2 and 3, and a state in which the compressive force gradually weakens toward the culvert of the water passage is created. Is issued.
上記のように生じる圧迫力により、通水路の二枚重ねフィルムは密着した状態で尾根状に褶曲する。この褶曲は自然な滑らかな曲面ではあるが、両側の斜面が急峻なヤセ尾根との表現が相応しい曲面を形成する（反対側からみればＵ字状渓谷との表現が相応しいことになる）。 Due to the compression force generated as described above, the double-ply film of the water passage is bent into a ridge shape in close contact. This fold is a natural, smooth curved surface, but forms a curved surface that is suitable for expression of a steep yase ridge on both sides (when viewed from the opposite side, a representation of a U-shaped valley is appropriate).
通水路が上記のように褶曲した状態で満水袋を写真のように横置きしても、まったく水は漏れなかった。そればかりでなく、この１０リットル容量の横置きした満水袋の上に２００キロ以上の荷重をかけたまま数日間放置しておいても、まったく水は漏れなかった。このような性能を実現できるまで十数ヶ月かけ、１００種類以上の溶着シール線パターンの袋を試作しては実証試験を行い、この発明を完成することができた。 Even when the full water bag was placed as shown in the photo with the water channel bent as described above, no water leaked. In addition, no water leaked even when left for several days with a load of 200 kg or more on this full-filled water bag of 10 liter capacity. It took ten months until such a performance was realized, and prototypes of over 100 types of welded seal line patterns were made, and a verification test was conducted to complete the present invention.
＝＝＝左右の突堤線１２・１３の作用＝＝＝
この発明のウォーターバッグの開発にあたり目標としたことのひとつは、満水袋を手提げしている状態から床に落としても、袋が壊れないことである。突堤線１２・１３を設けていない試作品では、落下時の衝撃によりＡ点やＢ点の近くでシール線が破断して満水袋が破裂することが少なくなかった。突堤線１２・１３は、落下時の袋下部からの衝撃的な水圧がＡ点やＢ点に作用するのを緩和するのに役立っているものと考えられ、これを設けることにより落下時の破裂が格段に少なくなった。
=== Operation of left and right jetty lines 12 and 13 ===
One of the targets for the development of the water bag of the present invention is that the bag will not be broken even if it is dropped from the hand-packed state to the floor. In the prototype without the jetty lines 12 and 13, it was not uncommon for the seal line to break near point A or point B due to the impact at the time of dropping, and the full water bag burst. The jetty lines 12 and 13 are thought to be helpful in mitigating the impact of shocking water pressure from the bottom of the bag at the time of dropping on point A and point B. There has been a significant decrease.
＝＝＝持ち手となる丸穴１４＝＝＝
図１に示すように、水の入っていない状態では、左右の内側の丸穴１４の間隔は１２０ｍｍあるが、袋を満水状態にすると丸穴間の通水路部分が上記のように褶曲するので、丸穴間の間隔は３０ｍｍほどに狭まり、片手の親指以外の四本指を４個の丸穴１４に通して満水袋を持ち運ぶのにちょうどよくなる。なお、袋の最上部の溶着シール線１６は、丸穴１４に指を通して手提げする際の補強の役割を担っている。
=== Round hole 14 to be a handle ===
As shown in FIG. 1, when there is no water, the distance between the left and right inner round holes 14 is 120 mm. However, when the bag is filled with water, the water passage portion between the round holes is bent as described above. The interval between the round holes is reduced to about 30 mm, and it is just good to carry a full bag by passing four fingers other than the thumb of one hand through the four round holes 14. In addition, the welding seal line 16 at the top of the bag plays a role of reinforcement when the finger is passed through the round hole 14 by hand.
＝＝＝袋から水を取り出す＝＝＝
たとえば、満水袋を図３のように机上に横置きし、上記のように褶曲している通水路の二枚重ねフィルムの外縁を手指を使って引き剥がし、給水時に用いたものと同様なホースをフィルム間に差し込み、その先端を通水路の奧まで到達させると、水はホースを通って袋から排出される。
=== Remove water from the bag ===
For example, a full water bag is placed on a desk as shown in FIG. 3, and the outer edge of the double-layer film of the water passage that is bent as described above is peeled off with fingers, and a hose similar to that used for water supply is filmed. Insert it in between and let its tip reach the end of the waterway, the water will be drained from the bag through the hose.
