Description
本開示は、概して、容器製造に関し、より具体的には、多障壁層の吹き込み成形された容器を製造するための方法に関する。
瓶および他の容器は、熱成形、回転成形、吹き込み成形、または押出吹き込み成形等の種々のプロセスによって製造され得る。容器は、単一または多層材料から生成され得る。障壁層は、そこから作製される容器にパッケージ化される食料または飲料製品の保存期間を延長するように、多層材料に含まれ得る。例えば、障壁層は、パッケージ化される製品が、ある気体、または揮発物、風味、もしくは香りの損失に敏感である場合に使用され得る。
一態様において、容器を作製する方法は、(i)少なくとも2つの障壁層および少なくとも2つのポリマー層を有する材料シートを提供することと、(ii)材料シートを管に形成することと、(iii)シール領域で管をシールすることと、(iv)管を吹き込み成形して、少なくとも2つの障壁層がシール領域で実質的に連続した障壁を形成する容器を形成することと、を含む。
本発明は、改善された障壁層性能を有する容器を製造するための方法を提供することによって、上で説明される必要性に対処する。容器および容器を作製するための方法のいくつかの実施形態を、以下で説明する。実施形態の異なるステップのパラメータ、構成要素、および特性は、別個に説明されるが、当業者によって理解されるであろうように、なお他の実施形態を可能にするように、この説明および特許請求の範囲と一貫して組み合わされ得る。
