従来、この種の流体用密封袋としては、先に本考案の考案者が開発した実願昭 ６２−１６６２６１号（実開平１−１６４１４２号）が知られており、その流体 用密封袋は、上記公開公報に開示されている通り、一端に流体の導入口を設ける と共に他端を閉塞した扁平な流体の導入管をプラスチックフィルムにより形成し 、この導入管の流体の導入方向に沿った少なくとも一側縁にはプラスチックフィ ルムから成る逆止弁を夫々内装した複数のプラスチックフィルム製の密封袋が並 列状態で一体に連設されると共に、導入管と各密封袋は逆止弁に設けた流路のみ を介して各別に連通可能に構成され、且つ相隣りする各密封袋はその側縁で一体 に連設されて構成されている。 Conventionally, as this type of fluid-tight bag, there has been known the Japanese Patent Application No. 62-166261 (actual Kaihei 1-164142) previously developed by the inventor of the present invention. As disclosed in the above-mentioned publication, a flat fluid introduction pipe having a fluid introduction port provided at one end and the other end closed is formed of a plastic film, and at least one of the introduction pipes along the fluid introduction direction is formed. On the side edge, a plurality of plastic film sealing bags each containing a check valve made of plastic film are connected in parallel in a row, and the introduction pipe and each sealing bag are provided on the check valve. Each of them is configured to be able to communicate with each other only through the flow path, and adjacent sealing bags are integrally connected at their side edges.
【０００３】[0003]
而して、上記の流体用密封袋は、その独自の構成に基づいて、同上公報に記載 されている優れた諸効果を達成し得ているが、その反面、各密封袋に内装された 逆止弁は、プラスチックフィルムにより扁平に形成した流体の流通管と、該流通 管内に装設した弁本体とから構成されており、この弁本体は、流体の流通方向に おいて、流体の流入口側に向って配置された、先端側に折曲部を備え、且つ基端 側に開放部を備えたプラスチックフィルムの二つ折り折曲片から成り、更にこの 弁本体の両側縁は上記流通管の両側縁に夫々接着されていて、上記弁本体の折曲 部により流体の流出阻止用の閉塞部が形成されると共に、流通管の両内側面と弁 本体の両外側面との間に夫々形成された間隙により流体の流路が形成されて構成 されているため、構造が複雑で生産コストが高いばかりでなく、流体の流路を成 す間隙が狭過ぎて各密封袋内への流体の導入を円滑に行ない難い問題がある。 Thus, the above-mentioned fluid-sealed bag can achieve the various advantageous effects described in the above publication based on its unique structure. The stop valve is composed of a fluid flow pipe formed flat with a plastic film and a valve main body installed in the flow pipe, and the valve main body has a fluid inlet port in the fluid flow direction. It is composed of two folded pieces of plastic film, which are arranged toward the side and have a bent portion on the distal end side and an open portion on the proximal end side. The valve body is adhered to both side edges to form a closed portion for preventing fluid outflow by the bent portion of the valve body, and is formed between both inner side surfaces of the flow pipe and both outer side surfaces of the valve body. Since the fluid flow path is formed by the created gap Structure not only has high complexity and production costs, there is a gap to forming the flow path of the fluid is too narrow problems smoothly hardly subjected to introduction of fluid into the sealed bag.
【０００４】 本考案は、上記の問題を解決することを課題として研究開発されたもので、上 記従来の流体用密封袋が有する特長の全てを備え、且つ各密封袋に内装する逆止 弁に創意工夫を加えることにより、各密封袋内への流体の導入を円滑に行ない得 ると共に、流体の逆流防止作用も抜群に良好である等の特長を備えたこの種の流 体用密封袋を安価に提供することを目的とする。The present invention has been researched and developed with the object of solving the above problems, and has all the features of the above-described conventional fluid-sealing bags, and a check valve incorporated in each sealing bag. By adding ingenuity to this, it is possible to smoothly introduce the fluid into each sealed bag, and this type of sealed bag for fluid has features such as excellent fluid backflow prevention. The purpose is to provide at low cost.
【０００５】[0005]
上記の課題を解決し、その目的を達成する手段として、本考案では、少なくと も一端に流体の導入口を備えたプラスチックフィルム（シート）製の扁平な流体 の導入管と、この導入管の流体の導入方向に沿った少なくとも一側縁に並列状態 で連設され且つ夫々の側縁で互いに連設された多数のプラスチックフィルム（シ ート）製の密封袋と、該各密封袋内に夫々各別に内装されたプラスチックフィル ム（シート）製の扁平な逆止弁とから成り、上記導入管と各密封袋を該各逆止弁 の流路のみを介して各別に連通可能に構成した流体用密封袋において、上記各逆 止弁は、２枚のプラスチックフィルム片を両側で接着して流体の流路を形成する と共に、その密封袋内への挿入側の先端部の所要長さの両側は接着されることな く、該先端部に遊離開放片を形成して構成されていることを特徴とする流体用密 封袋を開発し、採用した。 As a means for solving the above-mentioned problems and achieving the object, in the present invention, a flat fluid introduction pipe made of a plastic film (sheet) having a fluid introduction port at least at one end, and this introduction pipe A large number of sealing bags made of plastic films (sheets), which are continuously arranged in parallel with each other on at least one side edge along the fluid introduction direction and are connected to each other at each side edge, and inside each of the sealing bags. Each of them is composed of a flat check valve made of plastic film (seat), which is individually installed inside, and the introduction pipe and each sealing bag are configured to be able to communicate with each other only through the flow path of each check valve. In the sealed bag for fluid, each of the above-mentioned check valves forms a fluid flow path by adhering two plastic film pieces on both sides, and the required length of the tip end on the insertion side into the sealed bag. Both sides are not glued to the tip Developed a fluid-tight seal bag, characterized in that it is constituted by forming a release opening piece was adopted.
【０００６】 また、本考案では、上記のように構成した流体用密封袋において、流体の導入 管の他端が閉塞されていることを特徴とする流体用密封袋、及び流体の導入管の 他端が開放されていることを特徴とする流体用密封袋、及び流体の導入管の一側 縁に多数の密封袋が連設されていることを特徴とする流体用密封袋、及び流体の 導入管の両側縁に多数の密封袋が連設されていることを特徴とする流体用密封袋 、及び逆止弁を形成している２枚のプラスチックフィルム片が流路において部分 的に接着されて該流路が部分的に狭められていることを特徴とする流体用密封袋 を夫々開発し、採用した。Further, in the present invention, in the fluid-sealed bag configured as described above, the fluid-sealed bag is characterized in that the other end of the fluid-introduced tube is closed, and A fluid-tight bag having an open end, and a fluid-tight bag characterized in that a large number of air-tight bags are connected to one side of a fluid-introducing pipe, and a fluid-inlet bag. A fluid-sealing bag characterized in that a number of sealing bags are connected to both side edges of the pipe, and two pieces of plastic film forming a check valve are partially bonded in a flow path. We have developed and adopted fluid-tight bags that are characterized in that the flow paths are partially narrowed.
【０００７】[0007]
本考案に係る流体用密封袋は、上記のように構成されているので、その導入管 の他端が閉塞されているタイプのものの場合は、そのまゝの状態で、また、導入 管の他端が開放されているタイプのものの場合は、該導入管の奥部の適所を押圧 具等により押えて開放側を閉塞した状態で、該導入管の導入口から流体、例えば 空気を供給圧入すると、空気は導入管を経てその閉塞側の一番奥に連設した密封 袋から順次に各逆止弁に設けた流路を介して各密封袋内に充填され、各密封袋を 膨満する。 Since the fluid-tight bag according to the present invention is constructed as described above, when it is of a type in which the other end of the introduction pipe is closed, it is in that state as well as other introduction pipes. In the case of a type with an open end, if a fluid, for example, air is supplied under pressure from the inlet of the introduction pipe with the opening side closed by pressing an appropriate place in the inner part of the introduction pipe with a pressing tool or the like. The air is filled into each sealed bag from the sealed bag continuously provided at the innermost side on the closed side through the introduction pipe and sequentially through the flow path provided in each check valve to inflate each sealed bag.
【０００８】 各密封袋が膨満されると、その膨満空気圧により逆止弁の流路自体が加圧閉塞 されると共に、図７に略示するように逆止弁の遊離開放片が、流路を経て外部に 流出しようとする空気流の一瞬の吸引作用により引かれて、流路の先端部の流路 口に吸着され、該流路口を蓋状に閉塞するので、各密封袋に充填された空気は導 入管側に逆流することがない。When each of the sealed bags is inflated, the inflated air pressure pressurizes and closes the flow path itself of the check valve, and as shown in FIG. It is drawn by the momentary suction action of the air flow that tries to flow out through the flow path, is adsorbed by the flow path opening at the tip of the flow path, and closes the flow path opening like a lid, so that each sealed bag is filled. The air does not flow back to the inlet pipe side.
【０００９】 また、各密封袋に各別に空気が充填密封されているので、一つの密封袋が破損 して空気を放出しても他の密封袋の空気が放出されることはなく、したがって全 体的には密封袋としての機能を保持することになり、さらに、相隣りする各密封 袋を所要巾の融着部を介して連設しておけば、必要に応じてこの融着部を切断す ることにより、所要の密封袋を分離して独立した複数の密封袋が得られる。In addition, since each sealed bag is individually filled and sealed with air, even if one sealed bag is broken and air is discharged, the air in the other sealed bags is not discharged, and therefore, all the sealed bags are not discharged. Physically, the function as a sealed bag is maintained, and if the adjacent sealed bags are connected in series through a fusion section of a required width, this fusion section can be formed as needed. By cutting, the required sealed bags are separated to obtain a plurality of independent sealed bags.
【００１０】[0010]
以下に、本考案の実施例を添付図面に基づいて説明すれば、図１〜図７に示す 実施例において、本考案に係る流体用密封袋１は、２枚の長方形状の熱可塑性プ ラスチックフィルム（シート）を重ね合わせて所要個所を融着して形成した扁平 な流体の導入管２と、該導入管２の流体導入方向（長手方向）に沿った一側縁に 並列状に連設した多数の密封袋３と、該各密封袋３の連設辺縁において各密封袋 ３内に装設した逆止弁４とから構成されている。 Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In the embodiment shown in FIGS. 1 to 7, the fluid-sealing bag 1 according to the present invention comprises two rectangular thermoplastic plastics. A flat fluid introduction tube 2 formed by laminating films (sheets) and fusion-bonding required parts, and one side edge along the fluid introduction direction (longitudinal direction) of the introduction tube 2 continuously connected in parallel. It is composed of a large number of sealed bags 3 and check valves 4 installed in the sealed bags 3 at the peripheral edges of the sealed bags 3.
【００１１】 而して、上記導入管２は、上記プラスチックフィルムの周縁融着部ａの一方の 長辺側融着部ａ1と、該融着部ａ1から若干内側寄りの位置において融着部ａ1と 平行に融着した融着部ｂと、周縁融着部ａの一方の短辺側融着部ａ2の一部ａ2′ と、他方の短辺側において上記長辺側融着部ａ1と融着部ｂとの間の無融着部ｃ とにより形成されており、したがって、この導入管２は無溶着部ｃにより形成さ れた流体の導入口５を一端に備えると共に、融着部ａ2′により形成された閉塞 部６を他端に備えた扁平で細長い管状体で構成されている。[0011] In Thus fused, the introduction tube 2, the Nagahengawa fused portion a 1 of one of the peripheral fused portion a of the plastic film, in some positions of the inboard from said fusing unit a 1 The fused portion b fused in parallel with the portion a 1 , the part a 2 ′ of one short side fused portion a 2 of the peripheral fused portion a, and the long side fused portion on the other short side. It is formed by the non-fusion-bonded portion c between the welded portion a 1 and the fusion-bonded portion b. Therefore, the introduction pipe 2 has at one end a fluid inlet 5 formed by the non-fusion-bonded portion c. At the same time, it is composed of a flat and elongated tubular body having a closed portion 6 formed by the fused portion a 2 ′ at the other end.
【００１２】 また、上記密封袋３は、上記プラスチックフィルムの周縁融着部ａの他方の長 辺側融着部ａ1と、上記融着部ｂと、両方の短辺側融着部ａ2、ａ2と、他方の長 辺側融着部ａ1と融着部ｂとに亘り所要間隔を保って融着した複数条の若干広巾 の融着部ｄとにより構成されている。 なお、各密封袋３の上縁を形成している融着部ｂは、各密封袋３の中間部分に 対応する位置では融着されることなく、この無融着部ｅにより次に述べる各逆止 弁４の各密封袋３内への装設を可能にしたものである。Further, the hermetically sealed bag 3 has the other long side fusion portion a 1 of the peripheral edge fusion portion a of the plastic film, the fusion portion b, and both short side fusion portions a 2 of the plastic film. , A 2 and a plurality of slightly wide fused portions d that are fused at the required distance over the other long side fused portion a 1 and fused portion b. The fusion-bonding portion b forming the upper edge of each sealing bag 3 is not fused at a position corresponding to the middle portion of each sealing bag 3, and each of the fusion-free portions e will be described below. The check valve 4 can be installed in each sealed bag 3.
【００１３】 さらに、上記逆止弁４は、この実施例では、柔軟にして極く肉薄の二枚の先細 り長方形状のポリエチレンフィルム片を重ね合わせて、その両側縁を加熱接着し て形成した先細り状の流体の流路４ａと、該流路４ａの先端側に延設した、両側 縁が接着されていない短い二枚の遊離開放片４ｂ、４ｂとから構成されている。Further, in this embodiment, the check valve 4 is formed by stacking two soft and extremely thin taper-shaped rectangular polyethylene film pieces, and heat-bonding both side edges thereof. It is composed of a taper-shaped fluid flow path 4a and two short open release pieces 4b and 4b which are provided on the tip end side of the flow path 4a and whose both edges are not bonded.
【００１４】 而して、上記のように構成された各逆止弁４は、図２に示すように、導入管２ と各密封袋３の連設部（融着部ｂ）における無融着部ｅを介して各密封袋３内に 挿入され、逆止弁４の流路４ａの基端部の流路口４ｃの外側辺縁を無融着部ｅの 両内側面に融着ｆすることによって各密封袋３内に装設されるものであり、した がって各密封袋３は逆止弁４の流路４ａのみを介して導入管２と連通され、この ようにして導入管２の一側縁に多数の密封袋３が逆止弁４の流路４ａのみを介し て夫々連通可能に並列状態で連設された流体用密封袋を構成したものである。 なお、図において４ｄは逆止弁４の流路４ａの先端部の流路口を示している。As shown in FIG. 2, the check valves 4 configured as described above are non-fusion-bonded in the connecting portion (fusion-bonding portion b) of the introduction tube 2 and each sealing bag 3. It is inserted into each sealed bag 3 via the portion e, and the outer peripheral edge of the flow passage port 4c at the base end portion of the flow passage 4a of the check valve 4 is fused to both inner side surfaces of the non-fusion-bonded portion e. The sealing bags 3 are installed in the respective sealing bags 3, and thus the respective sealing bags 3 are communicated with the introducing pipe 2 only through the flow path 4a of the check valve 4, and thus the introducing pipe 2 is provided. A plurality of sealing bags 3 are connected to one side edge of the check valve 4 in parallel so that they can communicate with each other only via the flow passage 4a of the check valve 4. In the figure, 4d indicates a flow passage port at the tip of the flow passage 4a of the check valve 4.
【００１５】 上記のように構成された流体用密封袋の各密封袋３内に気体を吹込む際は、導 入管２の導入口５に給気具の給気口を挿入して給気すればよく、給気された気体 は、先づ導入管２を経て一番奥部に位置する密封袋３の逆止弁４の上述した流路 を経て密封袋３内に充填され、順次に奥の方から各密封袋３内に円滑に充填され て各密封袋を膨満するものである。When the gas is blown into each of the airtight bags 3 of the fluid airtight bag configured as described above, the air supply port of the air supply device is inserted into the introduction port 5 of the introduction pipe 2 to supply air. It is sufficient that the supplied gas is first filled in the sealing bag 3 through the above-mentioned flow path of the check valve 4 of the sealing bag 3 located at the innermost part through the introduction pipe 2 first, and then sequentially in the back. In this way, each of the sealed bags 3 is smoothly filled from the above side to inflate each sealed bag.
【００１６】 給気により各密封袋３が膨満されると、その膨満空気圧により逆止弁４の流路 ４ａが全外周面から加圧されて閉塞されると共に、逆止弁４の遊離開放片４ｂ、 ４ｂが、流路４ａを経て外部に流出しようとする空気流の一瞬の吸引作用により 引かれて、流路４ａの先端部の流路口４ｄに吸着され、該流路口４ｄを蓋状に閉 塞するので、上記の閉塞作用と相俟って、空気の洩出を確実に防止するものであ る。When each of the sealed bags 3 is inflated by the air supply, the flow path 4a of the check valve 4 is pressed from the entire outer peripheral surface by the inflated air pressure to be closed, and the free opening piece of the check valve 4 is also closed. 4b, 4b are pulled by a momentary suction action of the air flow that tries to flow out through the flow path 4a, and are adsorbed by the flow path opening 4d at the tip of the flow path 4a, and the flow path opening 4d is covered. Since it is closed, the air leakage is surely prevented in combination with the above-mentioned closing action.
【００１７】 次に、上記実施例にしたがって主要な作用、効果を説明する。先づ、導入管２ の一側に連設した各密封袋３は、夫々各別の逆止弁４を備えているので、密封袋 ３の一つが破損して気体を放出することがあっても、他の密封袋３には影響を及 ぼすことがない。したがって、流体用密封袋全体としての機能を失わないので、 これを緩衝材、救命浮具或はボート等に適用した場合に、その緩衝性及び安全性 を著しく向上できる。Next, main actions and effects will be described according to the above-described embodiment. First, since each sealed bag 3 connected to one side of the introduction pipe 2 is provided with a check valve 4 respectively, one of the sealed bags 3 may be damaged and release gas. However, it does not affect the other sealed bags 3. Therefore, the function of the entire fluid-tight bag is not lost, and when it is applied to a cushioning material, a life preserver, a boat, etc., its cushioning property and safety can be remarkably improved.
【００１８】 また、相隣りする各密封袋３は若干広巾の融着部ｄを介して並設されているの で、この融着部ｄを介して各密封袋３を切断分離でき、したがって、物品の梱包 時等において融着部ｄから適宜の大きさに切断分離することにより緩衝材（詰め 物）としての使用上の便益性を向上し得る。Further, since the adjacent sealing bags 3 are juxtaposed with each other via the slightly wide fusion-bonding part d, the respective sealing bags 3 can be cut and separated via the fusion-bonding part d, and therefore, By cutting and separating the fused portion d into an appropriate size at the time of packing the article, the convenience of use as a cushioning material (filling material) can be improved.
【００１９】 さらに、前記したように、逆止弁４は密封袋３の膨満空気圧によって流路４ａ が平面的に加圧閉塞されるばかりでなく、逆止弁４の先端部に延設された遊離開 放片４ｂ、４ｂが、流路４ａを経て外部に流出しようとする空気流の一瞬の吸引 作用により引かれて、流路４ａの先端部の流路口４ｄを蓋状に閉塞するので、空 気の逆流を二段構えで防止でき、上記の効果を一層向上できる。Further, as described above, the check valve 4 not only planarly pressurizes and closes the flow path 4a by the full air pressure of the sealing bag 3, but also extends to the tip of the check valve 4. Since the free release pieces 4b, 4b are pulled by a momentary suction action of the air flow that tries to flow out through the flow path 4a, the flow path port 4d at the tip of the flow path 4a is closed like a lid. The backflow of air can be prevented by holding it in two stages, and the above effect can be further improved.
【００２０】 図８は本考案の他の実施例を示しており、流体の導入管２の他端を開放した点 においてのみ上記実施例と相違しており、その他の構造は全く同一である。この 実施例において各密封袋３に流体を充填する場合は、導入管２の所要個所をロー ラ、バー等で押圧閉塞して導入口５から流体を供納するものであり、この実施例 にしたがえば、所要の密封袋３のみに流体を充填できる利点がある。FIG. 8 shows another embodiment of the present invention, which is different from the above embodiment only in that the other end of the fluid introducing pipe 2 is opened, and the other structures are exactly the same. In this embodiment, when each sealing bag 3 is filled with a fluid, a required portion of the introduction pipe 2 is pressed and closed by a roller, a bar or the like and the fluid is delivered from the introduction port 5. Therefore, there is an advantage that only the required sealed bag 3 can be filled with the fluid.
【００２１】 図９は本考案の更に今一つの実施例を示しており、流体の導入管２の両側縁に 多数の密封袋３を連設した点においてのみ前記実施例と相違しており、その他の 構造は全く同一である。この実施例の場合は、各密封袋３に効率よく流体を充填 でき、且つ流体を充填した広面積の袋体を得られる利点がある。FIG. 9 shows still another embodiment of the present invention, which is different from the above embodiment only in that a large number of sealing bags 3 are connected to both side edges of the fluid introducing pipe 2. Have exactly the same structure. In the case of this embodiment, there is an advantage that each sealed bag 3 can be efficiently filled with a fluid, and a bag having a wide area filled with the fluid can be obtained.
【００２２】 図１０〜図１２は本考案で使用する逆止弁４の他の例を夫々示しており、流路 ４ａにおいて、頂部を逆止弁４の基端部の流路口４ｃ側に配置した山形状の接着 部７を設け、該山形状の接着部７により流路４ａ内に斜め外側に向う流体の狭い 分岐流路４ｅを設けた点で既述の逆止弁と相違しているが、この逆止弁４を使用 することにより次の独自の効果がもたらされる。FIGS. 10 to 12 respectively show other examples of the check valve 4 used in the present invention. In the flow passage 4 a, the top portion is arranged at the base end portion of the check valve 4 on the flow passage port 4 c side. The check valve is different from the check valve described above in that the mountain-shaped adhesive portion 7 is provided and the branch passage 4e for narrowing the fluid that flows obliquely outward is provided in the channel 4a by the mountain-shaped adhesive portion 7. However, the use of the check valve 4 has the following unique effect.
【００２３】 この逆止弁を介して各密封袋３内に充填封入された流体は、膨んだ袋体の復元 圧力或は流体の圧力により、外部に流出しようとしても、その圧力で、逆止弁４ における上下の異なった位置に形成された流路４ａ及び分岐路４ｅの夫々の両面 を圧迫して各流路を閉塞し、逆止弁の流路を二段構えで閉塞するので、流体の逆 流阻止効果を著しく向上できる。The fluid filled and sealed in each of the sealed bags 3 through the check valve, even if it tries to flow out to the outside due to the restoring pressure of the expanded bag body or the pressure of the fluid, the reverse pressure is applied. Since both sides of the flow passages 4a and the branch passages 4e formed at different positions in the vertical direction of the stop valve 4 are pressed to close each flow passage, and the flow passage of the check valve is closed by a two-stage structure, The backflow prevention effect of the fluid can be remarkably improved.
【００２４】 山形状の接着部７により形成された分岐流路４ｅは、各密封袋３の内方部に対 し斜め両外側に向って形成されていて、裾拡がり状になっているので、分岐流路 ４ｅの巾が狭いことと相俟って、流体の逆流阻止効果を格段に向上できる。The branch flow path 4e formed by the mountain-shaped adhesive portion 7 is formed so as to face both inner sides of the respective sealing bags 3 obliquely outwards and has a hem-shaped spread. Combined with the narrow width of the branch flow path 4e, the backflow prevention effect of the fluid can be significantly improved.
【００２５】 分岐流路４ｅは、上記のように各密封袋３の内方部に対し斜め両外側に向って 形成されているので、該分岐流路４ｅが狭くても、流体を円滑に供給導入できる 。As described above, the branch flow passage 4e is formed so as to face the inner portions of the respective sealing bags 3 obliquely outward and outward, so that the fluid can be smoothly supplied even if the branch flow passage 4e is narrow. Can be introduced.
【００２６】 なお、図１１の符号８及び図１２の符号９は、夫々上記山形状の接着部７の下 側において流路に施された直線状の接着部及び人形状の接着部を夫々示しており 、これらの接着部を付加することによって逆止弁としての流体の逆流防止効果は 一層向上されるものである。Note that the reference numeral 8 in FIG. 11 and the reference numeral 9 in FIG. 12 respectively indicate a linear adhesive portion and a human-shaped adhesive portion provided in the flow path below the mountain-shaped adhesive portion 7, respectively. Therefore, the effect of preventing the backflow of fluid as a check valve is further improved by adding these adhesive portions.
【００２７】 以上、本考案の主要な実施例について詳述したが、本考案は上記実施例に限定 されるものではなく、考案の目的を達成でき、且つ考案の要旨を逸脱しない範囲 内で、種々の設計変更が可能であることは当然であって、例えば逆止弁４の先端 部の流路口４ｄを蓋状に閉塞するための遊離開放片４ｂ、４ｂの形状、大きさは 、閉塞効果の向上を計って最適のものを選択できるものである。Although the main embodiments of the present invention have been described in detail above, the present invention is not limited to the above-mentioned embodiments, and the scope of the invention can be achieved and the scope of the invention is not deviated. It goes without saying that various design changes can be made. For example, the shape and size of the release opening pieces 4b and 4b for closing the passage opening 4d at the tip of the check valve 4 in a lid shape are different from each other.

本考案は、少なくとも一端に流体の導入口を備えたプラスチックフィルム（シ ート）製の扁平な流体の導入管と、この導入管の流体の導入方向に沿った少なく とも一側縁に並列状態で連設され且つ夫々の側縁で互いに連設された多数のプラ スチックフイルム（シート）製の密封袋と、該各密封内に夫々各別に内装された プラスチックフィルム（シート）製の扁平な逆止弁とから成り、上記導入管と各 密封袋を該各逆止弁の流路のみを介して各別に連通可能に構成した流体用密封袋 において、上記各逆止弁は、２枚のプラスチックフィルム片を両側で接着して流 体の流路を形成すると共に、その密封袋内への挿入側の先端部の所要長さの両側 は接着されることなく、該先端部に遊離開放片を形成して構成されていることを 特徴とする流体用密封袋に係るものであるから、次の優れた効果を達成できる。 The present invention provides a flat fluid introduction pipe made of a plastic film (sheet) having a fluid introduction port at least at one end, and a parallel state at least on one side edge along the fluid introduction direction of the introduction pipe. A plurality of plastic film (sheet) sealing bags which are connected to each other at their respective side edges, and a flat reverse bag made of a plastic film (sheet) which is separately installed in each of the sealing bags. A fluid sealing bag comprising a stop valve, wherein the introduction pipe and each sealing bag can communicate with each other only through the flow paths of the check valves, wherein each check valve is made of two plastics. The film pieces are adhered on both sides to form a fluid flow path, and both sides of the required length of the tip end on the insertion side into the sealed bag are not adhered, and the free open piece is attached to the tip end. A fluid characterized by being formed and configured Since those of the sealed bag, you can achieve the following excellent effects.
【００２９】 導入管の導入口から流体を供給することにより、多数の各密封袋に一度に能率 的に流体を充填し得ると共に、一度充填された流体は逆止弁の逆止作用により不 測に流出することがない。By supplying the fluid from the introduction port of the introduction pipe, it is possible to efficiently fill the fluid in each of the large number of sealed bags at one time, and the fluid once filled is unexpected due to the check function of the check valve. Never leaked to.
【００３０】 逆止弁は、密封袋の膨満空気圧によって流路が平面的に加圧閉塞されるばかり でなく、逆止弁の先端部に延設された遊離開放片が、流路を経て外部に流出しよ うとする空気流の一瞬の吸引作用により引かれて、流路の先端部の流路口に吸着 され、該流路口を蓋状に閉塞するので、空気の逆流を二段構えで防止でき、上記 の効果を一層向上できる。The check valve not only planarly pressurizes and closes the flow passage due to the full air pressure of the sealing bag, but also the free release piece extended at the tip of the check valve passes through the flow passage to the outside. It is drawn by the momentary suction action of the air flow that is about to flow out to the flow path, is adsorbed to the flow path opening at the tip of the flow path, and closes the flow path opening like a lid, preventing backflow of air with a two-stage stance. Therefore, the above effect can be further improved.
【００３１】 多数の密封袋のうちの或る密封袋が破損しても、流体の放出はその特定した密 封袋のみに限られて、密封袋全体としては流体の密封袋状態を保つことが可能で あるから、この密封袋を救命浮具、ボート、気球等に適用した場合に、その安全 性を著しく向上でき、また、緩衝材として使用した場合も緩衝効果を良好に保持 できる。Even if a certain one of the many sealed bags is broken, the discharge of the fluid is limited to the specified sealed bag, and the sealed bag as a whole can keep the sealed state of the fluid. Since this is possible, the safety of the sealed bag when applied to life-saving floats, boats, balloons, etc. can be remarkably improved, and when used as a cushioning material, the cushioning effect can be well maintained.
【００３２】 また、相隣りする密封袋を所要巾の融着部を介して連設しておけば、該融着部 から密封流体を全く放出させることなく各密封袋を切断分離できるので、密封袋 全体が大きい場合でも、これを適当な大きさに切断縮小でき、したがってこの密 封袋を物品梱包時の緩衝材（詰め物）としての使用する際に非常に便利であって 緩衝効果を向上できる。Further, if the adjacent sealed bags are continuously provided through the fusion-bonding part having a required width, the respective sealing bags can be cut and separated without releasing the sealing fluid from the fusion-bonding part. Even if the whole bag is large, it can be cut and reduced to an appropriate size, so it is very convenient and can improve the cushioning effect when using this sealed bag as a cushioning material (stuffing) when packing articles. ..
