Description

本発明は、輸送梱包に使用する、気体を緩衝体として利用した梱包用緩衝材、及びこれを使用する梱包物の中吊りエアー梱包方法に関する。   The present invention relates to a cushioning material for packing that uses a gas as a buffer and is used for transportation packaging, and an air-suspended air packing method that uses the cushioning material.

従来から家電製品、パソコン、電子精密機器製品等の物流における衝撃吸収材には発泡プラスチックによる緩衝材が使用されてきたが、今日では環境負荷を高める発泡プラスチックに代わって、紙製の緩衝材を使用するケースが増えている。   Conventionally, shock absorbers made from foamed plastics have been used as shock absorbers in logistics such as home appliances, personal computers, and electronic precision equipment products. Today, instead of foamed plastics, which increase the environmental impact, paper cushioning materials are used. Increasing use cases.

例えば、特許文献１では、緩衝材本体とそれに内装する繰込補強壁とが一枚の段ボールの展開型に形成され、そのうち緩衝材本体が矩形のケース形を基本形態とし、それに製品嵌着部が、その前面壁と上面壁との反転により形成される。また、それを補強するために、底壁と後面壁との間の折角に反する逆折りにより製品嵌着部へ向かってほぼ菱形錐形に押し上がる二つ割れの支持部を設け、二つに割れた左右支持折壁の上端にさらなる逆折りによるＶ折れ頂部を形成し、繰込補強壁には、製品嵌着部の段部と、Ｖ折れ頂部との間に挾持されるＬ字形の屈折段部を設けた段ボール製の組立緩衝材が開示されている。   For example, in Patent Document 1, a cushioning material main body and a reinforcement reinforcing wall built in the cushioning material main body are formed in a single cardboard development mold, of which the cushioning material main body has a rectangular case shape as a basic form, and a product fitting portion Is formed by reversing the front wall and the top wall. In addition, to reinforce it, there are provided two split support parts that push up into a roughly diamond-shaped cone toward the product fitting part by reverse folding against the folding angle between the bottom wall and the rear wall. A V-folded top portion is formed by further reverse folding at the upper end of the cracked left and right support folding walls, and an L-shaped refracting step held between the step portion of the product fitting portion and the V-folded top portion on the reinforcement reinforcing wall. An assembly cushioning material made of corrugated board provided with a portion is disclosed.

即ち、特許文献１に記載の発明では、一枚の展開型において組み立てることができるため、緩衝材本体の輸送時には、展開状態で積み重ねて輸送することができ、また組立て時においては、異なる部材の組合せを要することなく、一枚の段ボールだけで、その組立てをなし得る。
しかし、特許文献１では、保持体、支持体がそれぞれ、全体を１枚のダンボールで形成されているため、梱包物を支持する突片部の強度と、支持体を支える保持体の両側２面の強度が低く、一度衝撃を受けると、変形又は破損が発生し、次の衝撃を受けたときの耐衝撃性能が著しく低下するという問題があり、また、保持される梱包物の大きさや形状が限定され、他物品に対して流用がきかないという問題もある。 That is, in the invention described in Patent Document 1, since it can be assembled in a single unfolded mold, it can be stacked and transported in the unfolded state when transporting the cushioning body, and different members can be transported during assembly. The assembly can be performed with only one cardboard without requiring a combination.
However, in Patent Document 1, since the holding body and the support body are each formed of a single cardboard, the strength of the projecting piece portion that supports the package and the two sides of the holding body that supports the support body The strength of the product is low, and once subjected to an impact, deformation or breakage occurs, and there is a problem that the impact resistance performance is significantly reduced when the next impact is received. There is also a problem that it is limited and cannot be used for other articles.

また、特許文献２に記載の発明では、梱包物の周囲に沿って当接可能に形成された保持体と、前記保持体に交差状に結合され、前記梱包物を挟持可能に形成された支持体とを具備し、前記保持体と前記支持体の少なくとも一方に、外力に抗する補強手段を備えたことを特徴とする緩衝材が開示されている。
これにより、緩衝材の強度が高められ、衝撃を繰り返し受けても、その変形、破損を防止して、耐緩衝性能を高めることができる。 Further, in the invention described in Patent Document 2, a holding body formed so as to be able to contact along the periphery of the package, and a support that is coupled to the holding body in a cross shape so as to be able to sandwich the package. There is disclosed a cushioning material comprising a body, and at least one of the holding body and the support body is provided with reinforcing means against external force.
Thereby, the strength of the cushioning material is increased, and even when impact is repeatedly received, the deformation and breakage can be prevented and the buffering resistance can be enhanced.

特許文献１又は２に記載の発明では、紙製の緩衝材であるため、焼却廃棄がし易いという点で好ましいが、その製造過程が煩雑であり、またさらに、緩衝材のストックスペースを必要としたり、使用後の廃棄や処理が容易でないという問題がある。   In the invention described in Patent Document 1 or 2, since it is a paper cushioning material, it is preferable in that it is easy to be incinerated and discarded. However, the manufacturing process is complicated, and moreover, a buffer material stock space is required. In addition, there is a problem that disposal and processing after use are not easy.

そこで本発明は、上記問題点に鑑みてなされたもので、大きな衝撃を吸収でき、多種の物品に汎用的に使用することができ、製造の作業性が極めて容易であって、繰り返し使用することができる緩衝機能性のある梱包用緩衝材及びこれを用いる梱包物の中吊りエアー梱包方法を提供することを課題とする。   Therefore, the present invention has been made in view of the above-mentioned problems, can absorb a large impact, can be used for a wide variety of articles, is extremely easy to work, and can be used repeatedly. It is an object of the present invention to provide a cushioning material having a cushioning function and a method for packing a suspended air in a package using the cushioning material.

なお、図１では、シート部材Ｘは緩衝部１３と袋部１２とを横断させて設けられているが、本発明の梱包用緩衝材は、このような構成に限られるものではなく、シート部材Ｘが、緩衝部１３のみの部分に備えられるように設置されてもよく、また、例えば緩衝部１３及び袋部１２と、スリット部Ｓ３にまたがるように設置されてもよい。 The cushioning material 11 for packing according to the present embodiment has the above two overlapped identical and large plastic films on the sides 1a to 4a and the slits s1 to s4. It is formed by heat welding 4b, 1c to 4c.
In the present embodiment, the sheet member X is preliminarily bonded to the heat welding parts 1x to 3x and the partition part 4x on one film constituting the base 10 of the packing cushioning material. After being provided, the peripheral edge portion is heated and welded to form the cushioning body 11 for packing. Further, the heat welding portion 3x is heated and welded only at a position crossing the bag portion 12 indicated by t1 in FIG.
Thus, in a state where the sheet member X is provided on one plastic film in advance, the sheet member X is integrally provided by a simple welding operation by superimposing two plastic films and performing thermal welding. The packing cushion main body 11 can be formed efficiently.
The partition 4x is for forming a gas flow path q in the seat member X so that the seat member X functions as a kind of check valve.
In FIG. 1, the sheet member X is provided so as to cross the buffer portion 13 and the bag portion 12, but the packing cushioning material of the present invention is not limited to such a configuration. X may be installed so as to be provided only in the buffer part 13, or may be installed so as to straddle the buffer part 13, the bag part 12, and the slit part S 3, for example.

なお、本発明の梱包用緩衝材の基体１０には、緩衝部１３の角部に、角部溶着部１ｄないし４ｄを形成してもよい。
角部溶着部１ｄないし４ｄは、図１中に示すように、溶着部１ｂないし４ｂのうちのいずれかを延長した直線により、緩衝部１３の短手方向に横断させて施すこととしてもよく、あるいは、梱包用緩衝材の基体１０の対角線上の、袋部１２の頂点と梱包用緩衝材の基体１０の頂点とを結ぶ各直線により、備えることとしてもよい。なお、角部溶着部１ｄないし４ｄには、部分的接着部と部分的連通部ｐを交互に設けるよう加熱接着が施されて、溶着部１ｄないし４ｄでの気体の流通が可能に構成される。
同様に、シート部材Ｘの溶着部２ｘにおいても、梱包用緩衝材本体１１の緩衝部１３に対して、気体流通可能となるよう、適宜部分的連通部ｐを設ける必要がある。 In addition, in the base 10 of the cushioning material for packing according to the present invention, the corner welded portions 1d to 4d may be formed at the corners of the buffer portion 13.
As shown in FIG. 1, the corner welded portions 1d to 4d may be applied by crossing in the short direction of the buffer portion 13 by a straight line extending any one of the welded portions 1b to 4b. Or it is good also as providing by each straight line which connects the vertex of the bag part 12 and the vertex of the base | substrate 10 of the packing cushioning material on the diagonal of the base | substrate 10 of the packing cushioning material. The corner welded portions 1d to 4d are heat-bonded so as to alternately provide partial adhesive portions and partial communication portions p so that gas can be circulated in the welded portions 1d to 4d. .
Similarly, also in the welding part 2x of the sheet | seat member X, it is necessary to provide the partial communication part p suitably so that gas distribution is possible with respect to the buffer part 13 of the buffer material main body 11 for packing.

なお、この実施形態においては、前記梱包溶緩衝材の基体１０を構成する可撓性フィルムは、ポリエチレンやポリプロピレンなどヒートシール性を有するプラスチックフィルムと、ポリアミドやフッ素樹脂、シリコン等のフィルムとをラミネートしたものである。
プラスチックフィルムの一方の面に、ヒートシール性のある材質が現れるようにしたのは、梱包溶緩衝材本体１１を製袋するために、内側の表面同士を熱溶着する必要があるからである。また、もう一方のフィルムは、ガス透過性を考慮して設けたものである。
なお、本発明の梱包用緩衝材の基体１０を構成するプラスチックフィルムは、ポリアミドやフッ素樹脂、シリコン等のフィルムを挟んで、その両表面に、ポリエチレンやポリプロピレンなどヒートシール性を有するフィルムをラミネートする構成としてもよい。
このようにすることで、製袋された梱包用緩衝材の基体１０の、外側の表面同士を熱溶着することができ、梱包用緩衝材本体１１を更に立体成形することが可能となる。
また、間に挟むフィルムは、アルミ製フィルム等の、金属製フィルムを挟むこととすることを可能である。 In this embodiment, the flexible film constituting the base 10 of the packing solution buffer material is a laminate of a heat-sealing plastic film such as polyethylene or polypropylene and a film such as polyamide, fluororesin, or silicon. It is a thing.
The reason why the heat-sealable material appears on one surface of the plastic film is that it is necessary to heat-weld the inner surfaces to form a bag for the packing buffer material body 11. The other film is provided in consideration of gas permeability.
The plastic film constituting the base 10 of the packing cushioning material of the present invention is laminated with a film having heat sealing properties such as polyethylene or polypropylene on both surfaces of a film made of polyamide, fluororesin, silicon or the like. It is good also as a structure.
By doing in this way, the outer surfaces of the packaging cushion base material 10 which has been formed can be thermally welded, and the packaging cushion body 11 can be further three-dimensionally molded.
Further, the film sandwiched therebetween can be a metal film such as an aluminum film.

本発明に係る梱包用緩衝材の基体１０の製袋工程においては、梱包用緩衝材本体１１を構成する前記２枚のプラスチックフィルムの間に、前記シート部材Ｘを挟み、梱包用緩衝材本体１１の部分的連通部にあたる個所の表フィルム及び裏フィルムの内部に、予め耐熱性インク等の溶着阻害物質を塗布又はグラビア印刷しておく事等により剥離処理を施し、周縁部１ａないし４ａ及び溶着部１ｂないし４ｂ、１ｃないし４ｃ、角部溶着部１ｄないし４ｄ、さらに溶着部１ｘないし２ｘ、間仕切り部４ｘに対して一様に加熱接着を施しても、部分的連通部ｐを備えた梱包用緩衝材の基体１０を形成することができるため、製袋作業を簡易化する事ができる。   In the bag-making process of the packaging cushion base 10 according to the present invention, the sheet member X is sandwiched between the two plastic films constituting the packaging cushion body 11 to provide the packaging cushion body 11. The peripheral portions 1a to 4a and the welded portion are subjected to a peeling treatment by applying a coating-inhibiting substance such as heat-resistant ink or gravure printing in advance on the inside of the front film and the back film at the portion corresponding to the partial communication portion 1b to 4b, 1c to 4c, corner welded portions 1d to 4d, further welded portions 1x to 2x, and partitioning portion 4x, even if heat bonding is performed uniformly, packaging buffer having a partial communication portion p Since the base material 10 can be formed, the bag-making operation can be simplified.

本発明の梱包用緩衝材は、さらに、前記のように構成した図１に示す梱包用緩衝材本体１１の袋部１２の一側縁（図１中ｒで示す位置）を截断して、挿入口Ｒを形成するともに、溶着部１ｂないし４ｂと１ｃないし４ｃとの間の、図中Ｓ１ないしＳ４で示す位置を截断して、スリットＳ１ないしＳ４を形成して、図３で示すような構造を得るようにしたものである。
このように、本発明の梱包用緩衝材は、一枚のシートに対し、所定の位置に熱溶着及び截断を施す作業のみで製造することができるため、自動量産化が可能となり、電子精密機器や記録媒体等の製品を安定的に保持できる梱包用緩衝材を、極めて安価に提供することができる。
なお、図１中で示される梱包用緩衝材１１では、スリットＳ１ないしＳ４が、それぞれ間に連接部を設けず、一連の切り込みにより設けたものを示しているが、スリットの構造としてはこれに限られるものではなく、適宜連接部を設けて備えることとしてもよい。
また、挿入口Ｒを形成するための截断部ｒは、溶着部２ｃ及び４ｃを跨がずに備えられる。更に、袋部１２の挿入口Ｒでは、上下のフィルムの端部の位置に差ができるよう、挿入口Ｒの一方のフィルムの端部を、図１中で示すように切除して、挿入口Ｒからの被梱包物Ａの挿入を容易にするための段差切り込み部ｒ’を形成することが好ましい。 The packing cushioning material of the present invention is further inserted by cutting one side edge (position indicated by r in FIG. 1) of the bag portion 12 of the packaging cushioning material body 11 shown in FIG. 1 configured as described above. A structure as shown in FIG. 3 is formed by forming the opening R and cutting the positions indicated by S1 to S4 in the drawing between the welded portions 1b to 4b and 1c to 4c to form slits S1 to S4. It is something to get.
As described above, the packing cushioning material of the present invention can be manufactured only by performing heat welding and cutting at a predetermined position on a single sheet. And a cushioning material for packing that can stably hold products such as recording media can be provided at a very low cost.
In the packing cushioning material 11 shown in FIG. 1, the slits S1 to S4 are provided by a series of cuts without providing a connecting portion between them. It is not restricted and it is good also as providing a connection part suitably.
Moreover, the cutting part r for forming the insertion port R is provided without straddling the welding parts 2c and 4c. Further, at the insertion opening R of the bag portion 12, one film end of the insertion opening R is cut out as shown in FIG. It is preferable to form a step cut portion r ′ for facilitating insertion of the article A to be packed from R.

（使用形態）
次に、上記のように構成した梱包用緩衝材の使用状態を作用、効果と共に説明する。
前記シート部材Ｘは注気口としての役割を備えた一種の逆止弁であり、剥離剤を一帯に塗布し、溶着処理が施されないようにした気体供給部Ｊの気体注入部１４又は１５の位置に、図２中Ｊ′で示す方向で気体の注入管を挿入し、該注入管から気体を圧入すると、気体は供給路Ｊから部分的連通部ｐを通り、さらに気体の流通路ｑを通って、最終的に、シート部材端部３ｘの、緩衝部を横断している部分から、梱包用緩衝材本体１１の緩衝部１３へ流れ出る構造となっている。 (Usage form)
Next, the use state of the cushioning material for packing constituted as described above will be described together with the function and effect.
The sheet member X is a kind of check valve having a role as an air inlet, and a release agent is applied to the entire area so that the welding process is not performed. When a gas injection pipe is inserted into the position in the direction indicated by J ′ in FIG. 2 and gas is injected from the injection pipe, the gas passes through the partial communication part p from the supply path J, and further passes through the gas flow path q. Finally, the sheet member end portion 3x has a structure that flows out from the portion crossing the buffer portion to the buffer portion 13 of the cushioning material body 11 for packing.

すなわち、図１において、気体注入部１４から供給された気体は、シート部材Ｘ端部３ｘのｔ２で示す位置から緩衝部１３内に流入し、さらにこの気体は、角部溶着部１ｄ、４ｄ、３ｄ、２ｄにおける、各部分連通部を通過して、緩衝部１３全体を膨満する。なお、ここで緩衝部１３が膨満することで、その内圧により、シート部材Ｘにおける気体の流通路が塞がれ、内部に圧入された気体が逆流できない構造となっているものである。
図３は、本発明の梱包用緩衝材に、気体が供給された後の状態を示す概略図である。
なお、シート部材Ｘにおいて、シート部材端部（溶着部）３ｘの、袋部１２を横断する部分（図１中ｔ１で示す部分）には、一帯に熱溶着を施されているため、気体供給路Ｊを通過する気体は、袋部１２を横断する部分においては外部に流出せず、緩衝部１３を横断する部分においてのみ、シート部材Ｘ端部３ｘより流出し、緩衝部１３のみを膨満させる。
なお、緩衝部１３に気体を供給する際は、気体注入部１４、１５双方から気体を供給して、シート部材端部３ｘのｔ３で示す位置からも、気体が緩衝部１３内に供給されるようにすることも可能である。 That is, in FIG. 1, the gas supplied from the gas injection part 14 flows into the buffer part 13 from the position indicated by t <b> 2 of the sheet member X end part 3 x, and this gas further flows into the corner welded parts 1 d, 4 d, It passes through each partial communication part in 3d and 2d, and the buffer part 13 whole is expanded. In addition, when the buffer part 13 swells here, the flow path of the gas in the sheet | seat member X is obstruct | occluded by the internal pressure, and it has the structure where the gas press-fit inside cannot flow backward.
FIG. 3 is a schematic view showing a state after gas is supplied to the packing cushioning material of the present invention.
In addition, in the sheet member X, the portion (the portion indicated by t1 in FIG. 1) of the sheet member end portion (welded portion) 3x that crosses the bag portion 12 is thermally welded all over, so that the gas supply The gas passing through the path J does not flow out to the outside in the portion crossing the bag portion 12, flows out from the sheet member X end portion 3 x only in the portion crossing the buffer portion 13, and expands only the buffer portion 13. .
In addition, when supplying gas to the buffer part 13, gas is supplied from both the gas injection | pouring parts 14 and 15, and gas is supplied in the buffer part 13 also from the position shown by t3 of the sheet | seat member edge part 3x. It is also possible to do so.

図３中に示すように、本実施形態に係る梱包用緩衝材１１に気体が供給されると、緩衝部１３が膨満すると同時に、袋部１２と緩衝部１３との間の切り込みにより、スリットＳ１ないしＳ４が形成され、接合部ｇにおいて袋部１２は緩衝部１３側に引っ張られて、中吊りされた状態となる。
被梱包物Ａは、袋部１２の一側縁を截断して形成された梱包物挿入口Ｒより、袋部１２の二枚のプラスチックフィルムの間に挿入されて、挟持される。
なお、緩衝部１３に気体が供給されることにより、上述したように袋部１２が緩衝部１３側に引っ張られることで、梱包物挿入口Ｒがふさがり、袋部１２に挿入された被梱包物Ａが、外部に抜け落ちるのが防止される。
また袋部１２は、袋部１２と緩衝部１３の間に形成されたスリットｓ１〜ｓ４により、緩衝部１３と切り離されているため、袋部１２が外部から衝撃を受けた際、その衝撃が吸収される。
なお、上述したように、梱包物挿入口Ｒにおいて一方のフィルムの端部を切除して、上記のように段差切り込み部ｒ’を形成することで、フィルム同士が互いに密着するのを防止でき、梱包物Ａの挿入を容易に行うことができる。 As shown in FIG. 3, when gas is supplied to the packing cushioning material 11 according to this embodiment, the cushioning portion 13 swells, and at the same time, the slit S1 is cut by cutting between the bag portion 12 and the cushioning portion 13. Thru | or S4 is formed and the bag part 12 will be pulled in the buffer part 13 side in the junction part g, and will be in the state suspended inside.
The article A to be packed is inserted and sandwiched between the two plastic films of the bag portion 12 through the package insertion port R formed by cutting one side edge of the bag portion 12.
In addition, when the gas is supplied to the buffer portion 13 and the bag portion 12 is pulled toward the buffer portion 13 as described above, the package insertion port R is blocked and the packaged item inserted into the bag portion 12 is filled. A is prevented from falling outside.
Moreover, since the bag part 12 is separated from the buffer part 13 by slits s1 to s4 formed between the bag part 12 and the buffer part 13, when the bag part 12 receives an impact from the outside, the impact is generated. Absorbed.
In addition, as described above, it is possible to prevent the films from adhering to each other by cutting the end of one film at the package insertion opening R and forming the step cut portion r ′ as described above. The package A can be easily inserted.

なお、図２では、気体供給路Ｊから先に気体が流入する通路としての、気体流入路Ｉ一帯に、間仕切り部４ｘを狭い間隔で設け、これにより気体の逆流を阻止する構造としているが、このように気体の逆流を阻止する構造としては、これに限るものではなく、例えば図９で示すように、気体の流通方向Ｊ′と平行方向に設けられた部分的溶着部５ｘ、６ｘにより狭い気体の流通路ｑ、ｒを形成した、所謂迷路構造により内部に圧入された気体が逆流するのを阻止する構造としてもよい。   In addition, in FIG. 2, although it has the structure which provided the partition part 4x in the gas inflow path I whole area as a channel | path into which gas flows in first from the gas supply path J at a narrow space | interval, thereby preventing the backflow of gas, As described above, the structure for preventing the backflow of gas is not limited to this. For example, as shown in FIG. 9, it is narrower than the partial welds 5x and 6x provided in the direction parallel to the gas flow direction J '. A structure may be adopted in which the gas press-fitted inside is prevented from flowing backward by a so-called labyrinth structure in which the gas flow paths q and r are formed.

また、前記シート部材Ｘの代わりに、注気口の役割を備えた逆止弁Ｙを設け、内部に注入した気体が逆流するのを防ぐ手段としてもよい。図１０は、他の実施形態における、逆止弁Ｙの構造を示す概略図である。この逆止弁Ｙは、ポリエチレンフィルム等のプラスチックフィルムを二枚の長方形状にして重ね合わせ、その間に溶着阻害層を形成したもので、一体に備えられた注気口から、梱包用緩衝材本体１１のＫ′方向に気体を流通させ、梱包用緩衝材本体１１内に気体を導入し、その逆方向には気体の流通を阻止する構造を有している。
この種のプラスチック製逆止弁は周知であり、（例えば、特許文献３参照。）その詳細は省略する。 Further, instead of the sheet member X, a check valve Y having a role of an air inlet may be provided to prevent the gas injected therein from flowing backward. FIG. 10 is a schematic view showing the structure of the check valve Y in another embodiment. This check valve Y is made of a plastic film such as a polyethylene film, which is overlapped into two rectangular shapes, and a welding inhibition layer is formed between them. From the integrally provided air inlet, the cushioning material body for packing 11 has a structure in which a gas is circulated in the K ′ direction, the gas is introduced into the cushioning body 11 for packing, and the gas is prevented from flowing in the opposite direction.
This type of plastic check valve is well known (see, for example, Patent Document 3), and details thereof are omitted.

なお、緩衝部１３の角部を横断して、一帯に溶着部を形成した場合も、溶着部１ｄ〜４ｄに対して部分的接着部と部分的連通部ｐを交互に設けて加熱溶着を施してあるので、上記のように梱包用緩衝材本体１１内に供給された気体は、溶着部１ｄ〜４ｄの部分的連通部ｐを通って、梱包用緩衝材１１の緩衝部１３全体を、確実に膨満する事ができる。   In addition, also when forming the welding part in one zone across the corner | angular part of the buffer part 13, the partial adhesion part and the partial communication part p are alternately provided with respect to the welding parts 1d-4d, and heat welding is performed. Therefore, the gas supplied into the packing material body 11 for packing as described above passes through the partial communication portions p of the welded portions 1d to 4d and reliably passes the entire buffer portion 13 of the packing material 11 for packing. Can be full.

図４は、本発明に係る梱包用緩衝材１１の緩衝部１３内部に、気体を供給した後の状態を示す斜視図である。
このとき、図１で示すように、緩衝部１３に角部溶着部１ｄないし４ｄを形成することで、気体注入部１４又は１５より気体が供給された際に、緩衝部１３の角部が側縁部より高く盛り上がるのを防ぐことができる。これにより、緩衝部１３の底面が平面に対して平坦に当たり、袋部１２内部に、被梱包物Ａを安定した状態で装着することができる。
なお、角部溶着部１ｄ〜４ｄを、溶着部１ｂないし４ｂのうちのいずれかを延長した直線により緩衝部１３の短手方向に横断させて施した場合は、当該溶着部の延長直線における緩衝部１３の折り曲げが可能となり、緩衝部１３に自由度が生まれ、梱包用緩衝材の扱いを容易とする効果もある。 FIG. 4 is a perspective view showing a state after gas is supplied into the buffer portion 13 of the packing material 11 for packing according to the present invention.
At this time, as shown in FIG. 1, by forming the corner welded portions 1 d to 4 d in the buffer portion 13, when the gas is supplied from the gas injection portion 14 or 15, the corner portion of the buffer portion 13 is moved sideways. It is possible to prevent swelling higher than the edge. Thereby, the bottom face of the buffer part 13 hits flat with respect to a plane, and the to-be-packaged goods A can be mounted in a stable state inside the bag part 12.
In addition, when the corner | angular part weld parts 1d-4d are crossed in the transversal direction of the buffer part 13 by the straight line which extended any one of the weld parts 1b thru | or 4b, it buffers in the extension straight line of the said weld part The part 13 can be bent, and the buffer part 13 has a degree of freedom, and there is an effect that the handling of the cushioning material for packing is facilitated.

なお、図４で示す梱包用緩衝材１１は、注気口の役割を備えた逆止弁として、図１０で示される逆止弁Ｙを備えた構造のものを示しているが、梱包用緩衝材１１に備えられる逆止弁としては、これに限られるものではなく、例えば、図１中に示すような、シート部材Ｘを備えた構造としてもよい。また、図４で示される梱包用緩衝材１１は、袋部１２と緩衝部１３の間に備えられるスリットが、各辺において適宜連接部を備えて設けられているが、このスリットは、図１で示されるように、一連の切り込みを入れることで形成することも可能である。
また、図１に示す緩衝用緩衝材の基体１０では、フィルム本体の角部を曲線状とした構成としているが、図４で示すように、フィルム本体の角部を曲線状とせず、長方形のプラスチックフィルム（シート）を使用して、梱包用緩衝材の基体１０を製造することも可能である。 Note that the packing cushioning material 11 shown in FIG. 4 shows a structure having the check valve Y shown in FIG. The check valve provided in the material 11 is not limited to this, and for example, a structure provided with a seat member X as shown in FIG. In addition, the packing cushioning material 11 shown in FIG. 4 is provided with slits provided between the bag portion 12 and the cushioning portion 13 with appropriate connecting portions on each side. It can also be formed by making a series of cuts, as shown in FIG.
Further, in the buffer material base 10 for cushioning shown in FIG. 1, the corners of the film body are curved, but the corners of the film body are not curved, as shown in FIG. 4. It is also possible to manufacture the base 10 of the packing cushioning material using a plastic film (sheet).

本発明の梱包用緩衝材１１は、被包装物Ａを、袋部１２に挟持した状態で、外装ケースＢ内に収納される。このとき、外装ケースＢ内には、図５に示す２個の支持体Ｅ及びＦが、各々外装ケースＢ内壁に当接させた状態で対向して備えられ、この支持体Ｅ及びＦの間に、梱包用緩衝材の緩衝部１３が挿嵌される。
なお、この支持体は、図５及び図６で示すように、２個の別個の支持体として備えることとしてもよく、あるいは、これらが外装ケースＢ底面で一体につながった形状の、１個の支持体として備えることとしてもよい。
図６は、本発明の梱包用緩衝材が、外装ケースＢ内で支持体Ｅ及びＦの間に挿嵌された状態を示す斜視図である。このように緩衝部１３が支持体の間に挿嵌されたとき、袋部１２は、宙に浮いた状態となるため、外装ケースＢ内で梱包用緩衝材１１が衝撃を受けた際にも、袋部１２ではその衝撃力が大きく緩和される。
このため、本発明の梱包用緩衝材１１を使用した中吊りエアー梱包方法は、電子精密機器や記録媒体等の製品も、外装ケースＢ内で衝撃・損傷等を受けるのを確実に防止でき、安定した状態で輸送・保管を行うことができる。
なお、緩衝部１３の角部に溶着部１ｄ〜４ｄを設けて、気体が供給されたときに角部が盛り上がるのを防止することで、緩衝部１３が支持体Ｅ及びＦの間に確実に装着され、外装ケースＢ内で安定な梱包状態を維持することができる。 The cushioning material 11 for packing of this invention is accommodated in the exterior case B in the state which sandwiched the to-be-packaged object A in the bag part 12. FIG. At this time, in the outer case B, two supports E and F shown in FIG. 5 are provided to face each other in contact with the inner wall of the outer case B. Between the supports E and F, The buffer part 13 of the cushioning material for packing is inserted in.
In addition, as shown in FIG.5 and FIG.6, this support body is good also as providing as two separate support bodies, or one of these in the shape where these were connected integrally by the exterior case B bottom face. It is good also as providing as a support body.
FIG. 6 is a perspective view showing a state in which the packing cushioning material of the present invention is inserted between the supports E and F in the outer case B. FIG. When the buffer part 13 is inserted between the supports in this way, the bag part 12 is in a suspended state, so that even when the cushioning material 11 for packing in the exterior case B receives an impact. In the bag part 12, the impact force is greatly relieved.
For this reason, the suspended air packaging method using the cushioning material 11 for packing of the present invention can reliably prevent products such as electronic precision equipment and recording media from being impacted, damaged, etc. in the outer case B, It can be transported and stored in a stable state.
In addition, by providing the welded portions 1d to 4d at the corner portions of the buffer portion 13 and preventing the corner portions from rising when the gas is supplied, the buffer portion 13 is surely placed between the supports E and F. It is attached and a stable packing state can be maintained in the outer case B.

また、本発明の梱包用緩衝材を使用する他の実施形態としては、外装ケースＢ内で、支持体Ｅ及びＦの間に梱包用緩衝材本体１１を２個あるいは３個以上備え、これら梱包用緩衝材本体１１の間に、被梱包物Ａを挿入して保持することとしてもよい。
図７は、本発明の梱包用緩衝材が、外装ケース内で支持体Ｅ及びＦの間に２個挿嵌された状態を簡略に示す断面図である。
この場合、支持体Ｅ及びＦの間に挿嵌される２個の梱包用緩衝材は、それぞれ、緩衝部１３に気体を注入される前に、２つの梱包用緩衝材の基体１０を重ね合わせ、さらに溶着部１ａないし４ａ、１ｂないし４ｂ、及び１ｃないし４ｃに対し加熱溶着を施し、２つの梱包用緩衝材の基体１０を一体に形成した後に、前記と同様にして、それぞれの緩衝部１３に気体を注入されて、支持体Ｅ及びＦの間に挿嵌される。
なお、この使用形態では、被梱包物Ａは袋部１２に挿入されず、２つの梱包用緩衝材本体１１及び１１’の間の空間Ｃに挿入されて、保持される。このように、梱包用緩衝材１１本体の間に被梱包物Ａを保持することで、袋部１２で被梱包物Ａを保持する場合より、重量の重い物体を安定した状態で保持し、保管・輸送を行うことができる。 Further, as another embodiment using the cushioning material for packing of the present invention, two or three packing cushioning material bodies 11 are provided between the supports E and F in the outer case B, and these packings are provided. It is good also as inserting and hold | maintaining the to-be-packaged goods A between the buffer material main bodies 11 for an object.
FIG. 7 is a cross-sectional view schematically showing a state in which two packing cushioning materials of the present invention are inserted between the supports E and F in the exterior case.
In this case, the two cushioning materials to be inserted between the supports E and F are overlapped with each other before the gas is injected into the cushioning portion 13. Further, after heat-welding the welded portions 1a to 4a, 1b to 4b, and 1c to 4c to integrally form the two packing cushion base materials 10, the respective buffer portions 13 are formed in the same manner as described above. Gas is injected into the support E and F, and is inserted between the supports E and F.
In this form of use, the article to be packed A is not inserted into the bag portion 12 and is inserted into the space C between the two packing cushioning bodies 11 and 11 ′ and held. In this way, by holding the article to be packed A between the cushioning materials 11 for packing, it is possible to hold and store a heavy object in a more stable state than when holding the article to be packed A by the bag portion 12.・ It can be transported.

また、外装ケースＢ内に支持体Ｅ、Ｆを複数組備えて、外装ケースＢ内に複数の梱包用緩衝材を収納することも可能である。
図８は、外装ケース内に支持体Ｅ及びＦが複数組収納され、各支持体の間に、本発明の梱包用緩衝材が挿嵌された状態を簡略に示す断面図である。
これにより、外装ケースＢ内に、各袋部１２に被梱包物Ａを挿入した状態の梱包用緩衝材１１を、外装ケースＢ内に多数収納し、梱包することができる。
また、被梱包物Ａが軽量である場合には、支持体を使用せず、梱包用緩衝材のみを多数重ねた状態で梱包を行うことも可能である。 It is also possible to provide a plurality of sets of supports E and F in the outer case B and store a plurality of packing cushioning materials in the outer case B.
FIG. 8 is a cross-sectional view schematically showing a state where a plurality of sets of supports E and F are housed in the exterior case, and the packing cushioning material of the present invention is inserted between the supports.
As a result, a large number of cushioning materials 11 for packing in a state in which the articles to be packed A are inserted into the respective bag portions 12 can be stored in the outer case B and packed in the outer case B.
Moreover, when the to-be-packaged object A is lightweight, it is also possible to perform packing in a state where only a number of cushioning materials for packing are stacked without using a support.

またさらに、本発明の梱包用緩衝材１０は、単独で使用することも可能である。即ち、外装ケースＢ内に梱包用緩衝材本体１１を収納せず、袋部１２に被梱包物Ａを挟持したのみの状態で、輸送、保管を行うことも可能である。   Furthermore, the cushioning material 10 for packing of the present invention can be used alone. That is, it is also possible to transport and store the packaging cushion main body 11 in the outer case B and only hold the article A to be packed in the bag portion 12.
