Description

【発明の詳細な説明】 本発明は、断熱コンテナの絶縁構造に関する。
断熱コンテナの絶縁構造として、その外壁と内壁の間
の発泡ポリウレタンのような保温材を設けたものが知ら
れている。また、コンテナ壁面を、サンドウイッチ板と
同様の構造と密度をもつ均一な発泡材で形成することも
既知である。
このような構造の欠点は、損傷しやすいことである。
一般には脆く硬い絶縁層が短期間の使用により破損また
は破壊するから、絶縁作用が減退する。
また、サンドウイッチ板の場合には機械的な安定性に
欠ける。
本発明の課題はこのような欠点を解消することにあ
る。
この課題は、本発明に従う特許請求の範囲第１項に記
載の絶縁構造によって解決される。
衝撃吸収層は、柔軟弾性を有し独立気泡で構成される
軟質発泡材で形成され、カサ密度30〜35Kg/m3のものが
好ましい。そのようなプラスチック材料はポリウレタ
ン、PVC、とくにポリウレタンが適している。
これらの材料は、熱伝導率が、たとえば0.03〜0.04W/
mkのように低く、それ故に同時にコンテナの熱絶縁にも
適している。
衝撃吸収層の厚さは15〜30mm、とくに20〜25mmとする
のが好ましい。この層をコンテナ外壁の内面にとりつけ
るには、接着剤や粘着テープなどを用いることができ
る。別のとりつけ方としては、この層の材料自体がもつ
弾性を利用して嵌め込む方法もある。つまり、衝撃吸収
層の寸法をコンテナ外壁内面の寸法よりわずかに大きく
用意し、内面に向けて押し込んで、周囲に対して突っ張
った形でそこに固定するわけである。衝撃吸収層の表面
は、外壁内面に平行な平坦な形にすることもできるし、
内側へ若干張り出したアーチ形にすることもできる。
硬質発泡材の絶縁層のカサ密度は、30〜90Kg/m3、と
くに40〜50Kg/m3のものが好ましい。その厚さは20〜80m
m、とくに30〜50mmとするのが好適である。
この絶縁層のプラスチック材料としては、ポリウレタ
ンまたはPVC、とくに熱伝導率が0.02〜0.04W/mkの硬質P
VC発泡材が適している。
この保温層は、補強層で内張りしてコンテナの内側に
設ける。補強層としては、表面加工した鉄、ステンレ
ス、アルミニウムその他の金属、立体成形した、または
板状もしくは箔状などの強固な合成樹脂、または軽量発
泡材製の押出成形板などを使用することができる。
この補強材の被覆を施した保温層は、衝撃吸収層に対
して、いずれの部分でも強く結合しない状態で設ける。
すなわち、保温層が衝撃吸収層に接触していないか、ま
たは接触していても、強い圧力が加わってはいない状態
で設ける。もちろん、接着や粘着はしない。
本発明による絶縁構造は、コンテナ輸送時の使用や積
み上げ（フォークリフトによる）、コンベヤ、ころコン
ベヤ、巻揚げおよび運搬などのコンテナの取扱時に機械
的な損傷を受けず、また捩り力が作用しても機械的特性
および熱的特性を損うことがない。
第１図および第２図に、本発明の断熱コンテナの保温
構造を示した。
図において、１はコンテナ外壁であって、接着層1aに
より衝撃吸収層２が設けられている。３は絶縁層を示
し、その内面に補強層４が設けられている。
【図面の簡単な説明】
第１図は、本発明構造の一実施例を示すコンテナの横断
面図である。 第２図は、第１図の部分拡大断面図である。 １……（コンテナ）外壁 1a……接着層 ２……衝撃吸収層 ３……絶縁層 ４……補強層
