自己狭持型緩衝材  Self-contained cushioning material
技術分野 Technical field
この発明は、 物品を梱包するに際し、 物品を箱等の梱包容器に揷入する と緩衝材が物品に適合するとともに物品を狭持するタイプの緩衝材に関す るものである。 技術背景  The present invention relates to a cushioning material of a type in which, when packing an article into a packing container such as a box, the cushioning material conforms to the article and holds the article. Technology background
従前より梱包に使用されている緩衝材は、 発泡スチロールのように予め 収納する物品の外形に適合する形状に形成したものと、 エアキャップに代 表されるように無数の空気室からなる空気袋シートで物品を包装するもの、 予め任意の大きさに膨張させた空気袋を外箱と物品との空間に充填するも の、 ビーズ状の発泡スチロールなど細かい緩衝材を空間に充填するもの、 あるいは、 発泡ウレタンのように空間に流し込んで膨張させるもの、 紙製 のものなどが利用されていた。  Conventionally, cushioning materials used for packaging are foamed foam sheets, such as Styrofoam, that are formed in a shape that matches the outer shape of the articles to be stored in advance, and airbags consisting of countless air chambers, as represented by air caps. In the space between the outer box and the product, an air bag pre-inflated to an arbitrary size is filled into the space between the outer box and the product, or the space is filled with fine cushioning material such as bead-shaped styrofoam, or foaming Some materials, such as urethane, which flow into a space and expand, and those made of paper were used.
しかしながら、 世界的な環境保護意識の高まりにより発泡スチロールな ど焼却に適さない梱包資材は使用することが困難になってきた。  However, the growing awareness of environmental protection worldwide has made it difficult to use packaging materials that are not suitable for incineration, such as styrofoam.
そこで、 発泡スチロールに代わる緩衝材として様々な素材が提案されて きている。 例えば、 従来の発泡スチロールに代わる物としては微生物が分 解可能なでんぷん等の天然素材から形成した発泡性素材が提案され、 食品 トレーなどを中心に製品化が進められている。  Therefore, various materials have been proposed as cushioning materials in place of Styrofoam. For example, as an alternative to conventional styrofoam, effervescent materials formed from natural materials such as starch, which can be decomposed by microorganisms, have been proposed, and commercialization has been promoted mainly for food trays.
しかしながら、 空気圧を利用した緩衝材は、 相変わらず収納する物品に 卷いたり、 または予め膨張させた空気袋を空間に充填する範疇の粋を出て おらず、 従来の発泡スチロールのように物品の形状に予め適合するような 形状に形成することが困難であった。  However, the cushioning material using the air pressure still does not appear to be in the category of wrapping the article to be stored or filling the space with a pre-inflated air bag, and the shape of the article is similar to that of the conventional styrofoam. It was difficult to form a suitable shape.
また、 逆止弁等を備えた空気袋を梱包箱内の空間に揷入して外箱の蓋を してから空気を充填して内部空間を埋めるタイプのものもあるが、 膨張に より外箱を押し広げようとしてしまうために、 外箱が直方体を維持するこ とができずに各面が膨張してしまい、 箱を積み上げることが困難になって しまうという問題があった。 Also, insert an air bag equipped with a check valve, etc., into the space inside the packing box and close the lid of the outer box. There is also a type that fills the internal space by filling with air after that, but because the expansion tries to push out the outer box, the outer box can not maintain a rectangular parallelepiped and each surface expands This makes it difficult to stack boxes.
そこでこの発明の自己狭持型緩衝材は、 上記従来の課題を解決すると同 時に、 従来の発泡スチロールのように収納する物品の外形に予め適合し得 る形状に形成することができ、 さらには物品の固定機能に優れた緩衝材を 提供するものである。 発明の開示  Therefore, the self-holding cushioning material of the present invention can be formed into a shape that can be adapted to the outer shape of an article to be stored like a conventional styrofoam at the same time as solving the above-mentioned conventional problems. It provides a cushioning material with excellent fixing function. Disclosure of the invention
すなわちこの発明の自己狭持型緩衝材は、 それぞれチューブ型に形成し た第 1の空気室と第 2の空気室を、 第 1の空気室で第 2の空気室を挟むよ うに 3本並列 Lて設けるとともに、 全空気室は通路で連絡され、 収納物品 の周囲を抱き込むように使用する緩衝材において、 その内最外側の第 1の 空気室に挟まれた中央部の第 2の空気室が収納物品で押圧された場合に、 その押圧容積分の第 2の空気室内部の空気が両側の第 1の空気室に押し出 されて第 1の空気室を膨張させることで第 1の空気室の間隔が狭まること により収納物品を狭持することを特徴とするものである。  That is, in the self-holding cushioning material of the present invention, three tube-shaped first air chambers and three second air chambers are arranged in parallel so that the first air chamber sandwiches the second air chamber. All the air chambers are connected by passages, and the cushioning material used to embrace the perimeter of the stored goods is the second air at the center between the outermost first air chambers. When the chamber is pressed by the stored articles, the air in the second air chamber corresponding to the pressed volume is pushed out to the first air chambers on both sides to expand the first air chamber, thereby causing the first air chamber to expand. It is characterized in that the stored articles are held by narrowing the space between the air chambers.
またこの発明の自己狭持型緩衝材は、 それぞれチューブ型に形成した第 1の空気室と第 2の空気室を、 第 1の空気室で第 2の空気室を挟むように 3本並列して設けるとともに、 全空気室は通路で連絡され、 収納物品の周 囲を抱き込むように使用する緩衝材において、 その内最外側の第 1の空気 室に挟まれた中央部の第 2の空気室は常態における膨張時の横断面積が第 2の空気室よりも小さく、 中央部の第 2の空気室が内容物で押圧された場 合に、 その押圧容積分の第 2の空気室内部の空気が両側の第 1の空気室に 押し出されて第 1の空気室を膨張させることで第 1の空気室の間隔が狭ま ることにより内容物を狭持することを特徴とするものである。 In addition, the self-holding cushioning material of the present invention includes three tube-shaped first air chambers and two second air chambers arranged in parallel so that the first air chamber sandwiches the second air chamber. All the air chambers are connected by a passage, and the cushioning material used to embrace the surroundings of the stored goods is the second air at the center between the outermost first air chambers. The chamber has a smaller cross-sectional area when expanded in a normal state than the second air chamber, and when the second air chamber in the center is pressed by the contents, the second air chamber inside the second air chamber has an amount corresponding to the pressed volume. The air is pushed out to the first air chambers on both sides and expands the first air chamber, thereby reducing the distance between the first air chambers. This is characterized in that the contents are nipped by doing so.
さらに、 横断面が樋状に形成されてなること、 並列した空気室の隔壁が 断続的に溶着されてなることを特徴とするものである。  Furthermore, the cross section is formed in a gutter shape, and the partition walls of the parallel air chambers are intermittently welded.
さらにまた一の空気室を中心に複数の空気室をその周囲に放射状に連結 して設け、 中央の空気室は周囲の空気室と相互に通路で連絡され、 収納物 品の周囲を抱き込むように使用する緩衝材において、 中央部の空気室が内 容物で押圧された場合に、 その押圧容積分の中央の空気室内部の空気が周 囲の空気室に押し出されて膨張することで周囲の空気室の間隔が狭まるこ とにより内容物を狭持することを特徴とするものである。  Furthermore, a plurality of air chambers are radially connected around the center of one air chamber, and the center air chamber is interconnected with the surrounding air chambers by a passage so as to embrace the periphery of the stored items. When the center air chamber is pressed by an object, the air in the center air chamber corresponding to the pressed volume is pushed out into the surrounding air chamber and expanded to expand the surrounding air chamber. It is characterized in that the contents of the air chambers are held narrow by reducing the space between the air chambers.
また、 一文字のチューブ型に形成した棒状空気室の幅方向の両側相対位 置に、 翼状に側方空気室を突設せしめるとともに、 全空気室は通路で連絡 され、 収納物品の周囲を抱き込むように使用する緩衝材において、 この棒 状空気室が内容物で押圧された場合に、 その押圧容積分の棒状空気室內部 の空気が両側の側方空気室に押し出されて膨張することで側方空気室の間 隔が狭まることにより内容物を狭持することを特徴とするものである。  In addition, wing-shaped side air chambers are protrudingly provided at the relative positions on both sides in the width direction of a single-shaped tube-shaped air chamber, and all air chambers are connected by passages to embrace the periphery of stored items. When the rod-shaped air chamber is pressed by the contents in the cushioning material used as described above, the air in the rod-shaped air chamber 分 の portion corresponding to the pressed volume is pushed out to the side air chambers on both sides and expanded, so that the side is expanded. It is characterized by holding the contents by narrowing the space between the two air chambers.

第 4図は製造工程を示すものである。 第 4図 （ i ) のように一枚の素材 シート 9を、 または （ii ) に示すように複数の素材シート 9を両側を対向 する M字形に折り （中折り）、 それぞれ矢印の部分を溶着する。 そして所望 位置に逆止弁 8を備えて周縁を溶着すると第 5図に示すように 3つの空気 室を並列して備えた空気袋ができあがる。 空気室を仕切る溶着部 5の間隔 Cを収納する物品の厚さに合わせておく と、 空気.を充填して膨張させたと きに内側に引き寄せられて物品の厚さよりも若干小さめになる。  FIG. 4 shows the manufacturing process. Fold one material sheet 9 as shown in Fig. 4 (i) or multiple material sheets 9 as shown in (ii) into an M-shape with both sides facing each other (center fold), and weld the parts indicated by arrows respectively I do. Then, when a check valve 8 is provided at a desired position and the periphery is welded, an air bag having three air chambers arranged in parallel is completed as shown in FIG. If the gap C between the welds 5 that partition the air chamber is adjusted to the thickness of the article to be stored, when the air is filled and inflated, it is drawn inward and becomes slightly smaller than the thickness of the article.
この緩衝材 1を形成する素材シート 9はポリエチレン、 ポリプロピレン などの単一素材の樹脂製シートの他、 これらを重ね合わせるなど複合させ たラミネートシート素材が好適である。 ここで用いる逆止弁 8は、 空気室 内の空気が外部に容易に漏れない構造のものであれば、 形式や構造は問わ ない。 また、 空気を充填 ·排出により繰り返し使用するためには弁を設け ることが望ましいが、 常時膨張させたまま使用するのであれば逆止弁を必 ずしも設ける必要はない。  The material sheet 9 for forming the cushioning material 1 is preferably a resin sheet of a single material such as polyethylene or polypropylene, or a laminated sheet material in which these are laminated and combined. The check valve 8 used here may be of any type or structure as long as the air in the air chamber does not easily leak to the outside. In addition, it is desirable to provide a valve in order to use the air repeatedly by filling and discharging air, but it is not always necessary to provide a check valve if the air is always used while inflated.
第 6図は完成したこの緩衝材 1に若干の空気が入った状態の横断面を示 している。 両側の内側に折り返された部分 1 0は内部に空気を充填させる と外側に膨張展張する。 以上のように構成したこの緩衝材 1の使用に際しては以下の通りである。 第 7図は梱包用の箱 1 1の内面に装着した状態を示している。 第 7図及 び第 8図はそれぞれ蓋 1 2の開閉方向の違いを示しているのみである。 第 9図及ぴ第 1 0図は空気を充填し、 物品を納める前の常態の要部横断 面図である。 第 9図において外箱の側壁は省略している。 外箱の内面壁 （ 第 9図では底面） 1 3には断面の小さい第 2の空気室 3のみを接着剤や粘 着テープ等 1 6を用いて固定し、 両側の第 1の空気室 2は固定しないでお く。 そうすることにより図中破線で示すように第 2の空気室 3が凹んだ樋 状になる。 このとき第 1 0図に示す両側の第 1の空気室 2の間隔 （=溶着 部間隔） Cは物品 1 4の厚さ Dより若干狭いのが望ましい。 この緩衝材 1 を向かい合った內面壁 1 3に装着すると物品 1 4を挿入する際の挿入ガイ ドとなる。 また、 第 1 2図に示すようにこのときの向かい合った第 2の空 気室 3の間隔 Lは物品 1 4の幅 Wよりも幾分小さめにすると良い。 FIG. 6 shows a cross section of the completed cushioning material 1 with a little air. The inside 10 folded inside on both sides expands and expands outward when filled with air. The use of the cushioning material 1 configured as described above is as follows. FIG. 7 shows a state where the package is mounted on the inner surface of the packing box 11. FIGS. 7 and 8 only show the difference in the opening and closing directions of the lid 12 respectively. Fig. 9 and Fig. 10 are cross-sectional views of main parts in a normal state before filling with air and storing articles. In FIG. 9, the side wall of the outer box is omitted. Only the second air chamber 3 with a small cross section is fixed to the inner wall of the outer box (bottom in Fig. 9) 13 with adhesive or adhesive tape 16 and the first air chamber 2 on both sides. Should not be fixed. By doing so, the second air chamber 3 has a concave gutter shape as shown by a broken line in the figure. At this time, it is desirable that the distance C between the first air chambers 2 on both sides shown in FIG. 10 (= the distance between the welded portions) is slightly smaller than the thickness D of the article 14. When the cushioning material 1 is attached to the facing wall 13, it serves as an insertion guide for inserting the article 14. Also, as shown in FIG. 12, the interval L between the second air chambers 3 facing each other at this time should be slightly smaller than the width W of the article 14.
このような 態で第 1 1図に示すように溝 1 5 (第 9図） に沿って物品 1 4を揷入すると、 第 1 3図に示すように第 2の空気室 3が物品 1 4で押 圧され、 その押圧された容積分の内部の空気が連絡通路 6を通って両側の 第一の空気室 2に流れ込む。 また、 第 2の空気室 3が押し込まれることで 連絡通路 6が外箱の壁 1 3に近づく。 この連絡通路 6は空気室の連結部分 でもあるから、 連絡通路 6が外箱の壁 1 3に近づくことで第一の空気室 2 が連絡通路 6に引っ張られて、 また連絡通路 6を回動軸として幾分相互に 内側に向かって回転する。  In this state, when the article 14 is inserted along the groove 15 (FIG. 9) as shown in FIG. 11, the second air chamber 3 is moved into the article 14 as shown in FIG. Then, the air inside the pressed volume flows through the communication passage 6 into the first air chambers 2 on both sides. Also, the communication passage 6 approaches the wall 13 of the outer box by pushing the second air chamber 3. Since the communication passage 6 is also a connecting portion of the air chamber, the first air chamber 2 is pulled by the communication passage 6 when the communication passage 6 approaches the wall 13 of the outer box, and the communication passage 6 is rotated. They rotate somewhat inward as axes.
そして第 1の空気室 2が膨張して物品 1 4を抱きこむように挟み付ける c この状態で物品 1 4が箱 1 1の中で移動しないようにするためには、 物品 1 4と外箱の壁 1 3 との実用間隙寸法 Ε以下に第 2空気室 3が圧縮されな い程度の空気圧を予め与えておくことが肝要である。 物品 1 4を挟み込む 力 （第 1の空気室内圧） は実際は図示しない外箱 1 1の側壁によって第 1 の空気室が両側 （図の左右方向） から内側に向かって押されるのでさらに 強いものとなる。 And to the first air chamber 2 is inflated pinches as Komu enfold article 1 4 c article 1 4 in this state is prevented from moving inside the box 1 1, the article 1 4 and the outer box It is important to provide in advance an air pressure that does not compress the second air chamber 3 below the practical gap dimension Ε of the wall 13. The force (first air chamber pressure) for sandwiching the article 14 is actually the first force by the side wall of the outer box 11 (not shown). The air chamber is pushed inward from both sides (left-right direction in the figure), making it even stronger.
そして第 1 2図に示すように上蓋 1 2を閉める。  Then, as shown in FIG. 12, the upper lid 12 is closed.
(実施例 2 ) (Example 2)
第 1 4図はこの発明の第 2の実施例を示すもので物品 1 4の厚さ寸法 D が大きい場合の実施形態を示している。 この場合には、 第 2の空気室 3を 二つ並列させて第 1の空気室 2の間隙を広げている。 なお、 第 2の空気室 3の並列数（図では 2 ) は物品 1 4の厚さに応じて適宜増減させれば良い。  FIG. 14 shows a second embodiment of the present invention, and shows an embodiment in which the thickness D of the article 14 is large. In this case, two second air chambers 3 are arranged in parallel to widen the gap between the first air chambers 2. Note that the number of parallel second air chambers 3 (2 in the figure) may be appropriately increased or decreased according to the thickness of the article 14.
(実施例 3 ) (Example 3)
上記実施例は第 5図に示すような、 収納する物品 1 4の各辺のほぼ全長 を狭持して緩衝するのに好適な実施形態を示したが、 第 1 6図及び第 1 7 図は物品 1 4の角部を狭持する場合の実施例 3を示すものである。  Although the above embodiment shows a preferred embodiment for holding and buffering almost the entire length of each side of the article 14 to be stored as shown in FIG. 5, FIG. 16 and FIG. Shows Example 3 where the corners of the article 14 are held.
つまり第 1 6図に示すように、 第 1.図に示したこの緩衝材 1の長手方向 の中間部分において、 両側の第 1の空気室 2を分断してくの字に切り込み を入れて溶着する。 こうすることにより、 空気を充填した際に折れ易くな り、 第 1 7図に示すように収納物品 1 4及び外箱 1 1の角部に適合する形 状になる。  In other words, as shown in FIG. 16, at the middle portion in the longitudinal direction of the cushioning material 1 shown in FIG. 1, the first air chambers 2 on both sides are cut off and welded by making cuts in the shape of a square. . By doing so, it becomes easy to break when filled with air, and the shape conforms to the corners of the article 14 and the outer box 11 as shown in FIG.
この緩衝材 1の作用は前述と同様であり、 外箱 1 1と収納物品 1 4との 間隙は確実に空気室で隔離されるので衝撃に対しても物品 1 4が箱 1 1内 で移動することがない。  The function of the cushioning material 1 is the same as that described above. Since the gap between the outer box 11 and the stored articles 14 is reliably isolated by the air chamber, the articles 14 move within the box 11 even in the event of an impact. I can't.
なお、 空気室の内圧は、 物品 1 4を収納した際に物品 1 4が箱 1 1内で 移動しないように確実に保持できる程度に圧力が上昇すれば良く、 物品 1 4揷入前の常態において十分な膨張を維持するほどの内圧を必要とするも のではない。 したがって、 物品 1 4揷入時に物品 1 4を狭持するような形 状になれば良く、 第 2の空気室 3が必ずしも第 1の空気室 2より断面が小 さくなければこの発明の全ての効果を得られないというものではない。 た だ、 当初より十分な空気圧で空気室が膨張してなおかつ樋状に形成されて いることにより、 物品 1 4の出し入れがし易いという更なる効果が得られ るものである。 The internal pressure of the air chamber only needs to be increased to such an extent that the article 14 can be securely held so that it does not move in the box 11 when the article 14 is stored. It does not require internal pressure to maintain sufficient inflation. Therefore, when the article 14 is inserted, the article 14 is held If the second air chamber 3 is not necessarily smaller in cross section than the first air chamber 2, not all effects of the present invention can be obtained. However, since the air chamber expands with a sufficient air pressure and is formed in a gutter shape from the beginning, a further effect that articles 14 can be easily taken in and out can be obtained.
この実施形態がより従来の発泡スチロールの緩衝材に近い形態と言え、 代用素材として最も理想的な形態といえる。  This embodiment can be said to be a form closer to the conventional cushioning material of polystyrene foam, and can be said to be the most ideal form as a substitute material.
(実施例 4 ) (Example 4)
次に第 1 8図乃至第 2 1図は第 4の実施例を示すものである。  Next, FIGS. 18 to 21 show a fourth embodiment.
第 1 8図は円形空気室 1 7を中央に置き、 その周囲に放射状に 3つの円 形空気室 1 8を連絡通路 6で連結しているものである。 また第 1 9図は正 方形空気室 1 9を中心に各辺の外側にさらに正方形空気室 2 0を連絡通路 6で連結しているものである。 いずれも 8は逆止弁である。 なお、 この場 合も常時膨張させた状態におくのであれば必ずしも逆止弁は必要ない。  In FIG. 18, a circular air chamber 17 is placed at the center, and three circular air chambers 18 are connected radially around the center by a communication passage 6. In FIG. 19, a square air chamber 20 is further connected to the outside of each side of the square air chamber 19 by a communication passage 6 with the square air chamber 19 as a center. In each case, 8 is a check valve. In this case, the check valve is not necessarily required if the airbag is always inflated.
これらは、 棒状の物品 2 1を筒状の梱包材 2 2に収納する場合に利用可 能な形態である。 すなわち第 2 0図及び第 2 1図に示すように、 中央の空 気室 1 7 ( 1 9 ) を棒状物品 2 1の端部に当たるように梱包材 2 2の底部 2 3に設ける。 前述の実施形態と同様に中央の空気室 1 7 ( 1 9 ) を物品 2 1で押すと押し込まれた容積分のその内部の空気が周囲の空気室 1 8 ( 2 0 ) に流れて膨張することにより、 物品 2 1を締め付けるというもので ある。  These are forms that can be used when the rod-shaped article 21 is stored in the cylindrical packing material 22. That is, as shown in FIGS. 20 and 21, a central air chamber 17 (19) is provided on the bottom 23 of the packing material 22 so as to contact the end of the rod-shaped article 21. When the article 21 presses the central air chamber 17 (19) with the article 21 as in the above-described embodiment, the internal air corresponding to the pushed volume flows into the surrounding air chamber 18 (20) and expands. Thus, the article 21 is tightened.
つまり第 1 8図は円筒または三角断面の筒状梱包材に、 第 1 9図は四角 断面の筒状梱包材に好適である。 なお、 収納する筒状梱包材の断面形状に 合わせて放射状に配した空気室 1 8の数を適宜変更させると良い。 (実施例 5 ) That is, FIG. 18 is suitable for a cylindrical packing material having a cylindrical or triangular cross section, and FIG. 19 is suitable for a cylindrical packing material having a square cross section. The number of radially arranged air chambers 18 may be changed as appropriate in accordance with the cross-sectional shape of the cylindrical packing material to be stored. (Example 5)
第 2 2図乃至第 2 7図は第 5の実施例を示すものである。  FIG. 22 to FIG. 27 show a fifth embodiment.
第 2 2図において、 この緩衝材 1は一文字チューブ型に形成した棒状空 室 2 4の幅方向の両側に、 側方空気室 2 5を翼状に設けた構造に形成さ れている。 第 2 2図において四角形に形成されているこの側方空気室 2 5 は、 棒状空気室 2 4との隔壁となる溶着部 5の途中に溶着をしない部分を 設けてこれを連絡通路 6とし、 棒状空気室 2 4と連通せしめている。 した がって内部に空気を充填するとまず棒状空気室 2 4が膨張し、 次いで各側 方空気室 2 5が膨張するようになっている。 第 2 2図において 8は逆止弁 である。 なお、 この側方空気室 2 5は第 2 2図に示すように四角形でなけ ればならない必要性はなく、 第 2 3図の （a ) 乃至 （ f ) に示すように、 三角形、 台形、 半円形、 円形、 逆三角形など使用する状況に応じた様々な 形状に形成すればよい。 また、 基本的な空気室の形成方法は実施例 1 と同 様に素材シート 9を重ね合わせて周囲及ぴ必要部分を熱溶着して形成され 。  In FIG. 22, this cushioning material 1 is formed in a structure in which a lateral air chamber 25 is provided in a wing shape on both sides in the width direction of a rod-shaped chamber 24 formed in a one-character tube shape. The side air chamber 25 formed in a square shape in FIG. 22 is provided with a non-welded part in the middle of a welding part 5 serving as a partition wall with the rod-shaped air chamber 24, and this is used as a communication passage 6, It communicates with the rod-shaped air chamber 24. Accordingly, when the inside is filled with air, first, the rod-shaped air chamber 24 expands, and then each side air chamber 25 expands. In FIG. 22, reference numeral 8 denotes a check valve. The side air chamber 25 need not be square as shown in FIG. 22, but as shown in FIGS. 23 (a) to (f), a triangle, trapezoid, It may be formed in various shapes such as a semicircle, a circle, and an inverted triangle depending on the use situation. As in the first embodiment, the basic air chamber is formed by laminating the material sheets 9 and heat-welding the surroundings and necessary parts.
第 2 4図はこの緩衝材 1に空気を充填した状態の第 2 2図の F F断面に おける横断面図である。 中央の棒状空気室 2 4に空気を充填するとまず棒 状空気室 2 4が膨張し、 一定の内圧になると連絡通路 6から空気が側方空 気室 2 5に流入して膨張する。 この際、 側方空気室 2 5はその場で単に膨 張するのみならず、 棒状空気室 2 4と側方空気室 2 5 との隔壁となる溶着 部 5の形成条件に応じて、 第 2 4図に示すようにややせり上がって横断面 (図において上面） が樋状になるのが望ましい。  FIG. 24 is a cross-sectional view taken along the line FF of FIG. 22 in a state where the cushioning material 1 is filled with air. When the central rod-shaped air chamber 24 is filled with air, the rod-shaped air chamber 24 first expands. When the internal pressure reaches a certain level, the air flows into the side air chamber 25 from the communication passage 6 and expands. At this time, the side air chamber 25 not only expands in place, but also depends on the conditions for forming the welding portion 5 serving as a partition wall between the rod-shaped air chamber 24 and the side air chamber 25. As shown in Fig. 4, it is desirable that the cross section (upper surface in the figure) becomes slightly gutter-like.
以上のように形成したこの緩衝材 1は第 2 5図に示すように、 中央の棒 状空気室 2 4に物品 1 4の重量がかかると押圧された容積分の空気が連通 口 6を通って両側の側方空気室 2 5内に流入する （前記第 1 3図及び第 1 5図も参照）。すると側方空気室 2 5の内圧が上昇する。 この際に側方空気 室 2 5がさらに上昇ないしは溶着部 5を回転軸に内側に回動してより樋形 状が強くなるように溶着部 5の条件を整えると良い。 そうすることにより 側方空気室 2 5の間隔 Cが狭まる方向に作用し物品 1 4を狭持する形とな る。 さらに梱包箱 1 1の内壁 1 3に押されるとさらに各空気室の内圧が上 がって梱包箱 1 1 と物体 1 4との空間を'埋めることになる。 As shown in FIG. 25, when the weight of the article 14 is applied to the central rod-shaped air chamber 24, the cushioning material 1 formed as described above passes through the communication port 6 for the pressed volume of air. Into the side air chambers 25 on both sides (see also FIGS. 13 and 15). Then, the internal pressure of the side air chamber 25 increases. In this case, the side air It is preferable to adjust the conditions of the welding portion 5 so that the chamber 25 is further raised or the welding portion 5 is rotated inward about the rotation axis to make the gutter shape stronger. As a result, the space C between the side air chambers 25 acts in a direction in which the space C is reduced, and the article 14 is held. Further, when pressed against the inner wall 13 of the packing box 11, the internal pressure of each air chamber further rises, and the space between the packing box 11 and the object 14 is filled.
第 2 6図及ぴ第 2 7図はこの緩衝材 1を用いて物品 1 4を梱包箱 1 1に 収納した状態を示している。 第 2 7図は第 2 6図の G G断面における縦断 面図である。 図では第 2 2図に示す形状に形成したこの緩衝材 1を上下向 かい合わせに 2本 （1対） 使用して、 物品 1 4の周囲各辺を狭持するよう に用いている。 物品の角部はチューブ状の棒状空気室 2 4を所望位置で屈 折させて使用する。 第 2 6図に示すように物品 1 4は梱包箱 1 1内におい てその縦横（図において紙面の上下左右）方向を棒状空気室 2 4で囲まれ、 そして第 2 7図に示すようにその厚さ （図において紙面の左右） 方向を側 方空気室 2 5で狭持される形となるので、 箱内で物品 1 4が移動する余裕 なく固定される。 .  FIGS. 26 and 27 show a state in which the article 14 is stored in the packing box 11 using the cushioning material 1. FIG. 27 is a longitudinal sectional view taken along the line GG of FIG. In the figure, two (one pair) of the cushioning materials 1 formed in the shape shown in FIG. 22 are used to face each other so as to sandwich each side of the article 14. The corner portion of the article is used by bending a tubular rod-shaped air chamber 24 at a desired position. As shown in FIG. 26, the article 14 is surrounded by a rod-shaped air chamber 24 in the vertical and horizontal directions (up, down, left, and right in the drawing) in the packing box 11, and as shown in FIG. Since the thickness (the left and right sides of the paper in the figure) is sandwiched by the side air chambers 25, the articles 14 are fixed without any room for movement in the box. .
なお、 第 2 6図では上下に 1対のこの緩衝材 1を使用したが、 これを物 品 1 4の外周寸法に合わせて 1本のものとしても良いことはもちろんであ る。 産業上の利用可能性  In FIG. 26, one pair of the cushioning materials 1 is used in the upper and lower directions, but it is a matter of course that one may be used in accordance with the outer dimensions of the article 14. Industrial applicability
この発明は以上のように構成したので、 従来の発泡スチロールに代わる 緩衝材として優れた物品保持機能と緩衝機能を発揮するものである。  Since the present invention is configured as described above, the present invention exhibits an excellent article holding function and an excellent cushioning function as a cushioning material replacing the conventional polystyrene foam.
空気室を中央部と側方部とで相互に連通しつつ別個に設けることにより、 収納物品の重量がかかる中央部の空気室に圧力がかかるほど側方の空気室 による狭着力が強まり梱包容器内で物品を確実に固定することができる。 そして横断面形状を樋状に形成することにより従来の空気袋型緩衝材に はなかった、 物品の形状に合わせた形状に形成するということが可能とな つた。 そして、 樋状に形成することにより、 物品の揷入ガイドとしても機 能させることができる。 By separately providing the air chambers at the center and the side while communicating with each other, the tighter the lateral air chambers become, the tighter the air chamber at the center where the weight of the stored articles is applied, the stronger the tightness of the side air chambers. The article can be securely fixed in the inside. And by forming the cross section in a gutter shape, it becomes a conventional air bag type cushioning material. No, it became possible to form the shape according to the shape of the article. And, by forming it in the shape of a gutter, it can function also as an introduction guide for articles.
さらに、 使用する直前に空気を充填すれば良いので、 使用前は潰れた袋 の状態 （フラッ ト） であるから収納場所を取ることがない。 さらには使用 後には逆止弁から空気を抜けば使用前の状態に戻すことができ、 また空気 を再充填すれば再使用することができる。 図面の簡単な説明  Furthermore, since it is only necessary to fill the air immediately before use, the bag is in a crushed state (flat) before use, so there is no need to take a storage space. Furthermore, after use, the air can be returned to the state before use by bleeding air from the check valve, and can be reused by refilling with air. BRIEF DESCRIPTION OF THE FIGURES
