Abstract
Description
本発明による容器のうち、酸素吸収性容器の場合であって被酸化物として国際公開第2012/105457号に記載された酸素吸収剤を使用した場合には、0~30%RHで保存されることが好ましいような低水分含有物や、水分を含まない物まで収容し、酸素吸収できる。低水分含有物としては、粉末スープ、粉末飲料、粉末菓子、調味料、穀物粉、栄養食品、健康食品、着色料、着香料、香辛料などの食品類;散薬類、粉石鹸、歯磨粉、工業薬品などの薬品類が挙げられ、形状としては粉末や顆粒、あるいはこれらを成形した錠剤を例示することができる。水分を含まない物としては、工業部品やアトルバスタチン、レボチロキシンなどの医薬品類が例示される。
(金属粉1の作製)
Al(アルミニウム)粉とFe(鉄)粉をそれぞれ50質量%の割合で混合し、窒素中で溶解して、Al-Fe合金を得た。得たAl-Fe合金はジョークラッシャー、ロールクラッシャー及びボールミルを用いて粉砕し、粉砕物を目開き200メッシュ(0.075mm)の網を用いて分級し、200メッシュ以下のAl-Fe合金を得た。得られたAl-Fe合金粉150gを、30質量%水酸化ナトリウム水溶液中、50℃で1時間攪拌混合した後、混合溶液を静置し上層液を取り除いた。残った沈殿物をpHが10以下になるまで蒸留水で洗浄し、Al-Fe多孔質金属粉である金属粉1を得た。金属粉1は、酸素に接触させることを回避すべく、水溶液中で保存した。
金属粉1と、直鎖状低密度ポリエチレン(日本ポリエチレン株式会社製;NF384A、密度0.926、以下「LLDPE」ともいう)とを、金属粉1:LLDPE=30:70(質量比)となるように、窒素ガスで置換したメインフィーダとサイドフィーダの2種類のフィーダを有する二軸押出機で溶融混練してストランド状に押出した後、ペレタイザーで裁断し、酸素吸収樹脂ペレット1を得た。LLDPEはメインフィーダにより投入し、溶融したLLDPEにサイドフィーダにより金属粉1を投入した。酸素吸収樹脂ペレット1の密度は約1.2g/cm3であった。
内側面から外側面へ、最内層(30)/中間層(酸素吸収層/接着剤層/ガスバリア層/接着性樹脂層)(32)/最外層(31)の6層構成を有する容量120mLの酸素吸収中空容器1を5種6層のダイレクトブロー成形機を用い、成形温度180℃で作製した。最内層(30)にはLLDPEを、中間層を構成する酸素吸収層には酸素吸収樹脂ペレット1を、ガスバリア層にはエチレンビニルアルコール共重合樹脂(株式会社クラレ製、商品名:エバール「F101B」)を、接着性樹脂層にはカルボン酸変性ポリオレフィン樹脂(三菱化学株式会社製、商品名:H511)を、それぞれ使用した。最外層(31)には密度0.948のHDPE(京葉ポリエチレン製、製品名;B5203)を使用した。
中空容器1の脱酸素日数(容器内の酸素濃度が0.1容量%以下となる日数)を以下の手順で測定した。
(金属粉2の作製)
平均粒径30μmの還元鉄粉500kgを加熱ジャケット付き真空混合乾燥機中に投入
し、-720mmHgの減圧下110℃で加熱しつつ、塩化カルシウム50重量%水溶液
5kgを噴霧、2時間乾燥した後、篩い分けして50μmより大きな粗粒を除き、金属粉2を得た。
金属粉2と、LLDPEとを、金属粉1:LLDPE=30:70(質量比)となるように、メインフィーダとサイドフィーダの2種類のフィーダを有する二軸押出機で溶融混練してストランド状に押出した後、ペレタイザーで裁断し、酸素吸収樹脂ペレット2を得た。LLDPEはメインフィーダにより投入し、溶融したLLDPEにサイドフィーダにより金属粉2を投入した。酸素吸収樹脂ペレット2の密度は約1.3g/cm3であった。
酸素吸収樹脂ペレット1に代えて酸素吸収樹脂ペレット2を用いたこと以外は実施例1と同様にして酸素吸収中空容器2を作製した。
中空容器2の脱酸素日数(容器内の酸素濃度が0.1容量%以下となる日数)を以下の手順で測定した。
