Abstract
Description
各種樹脂を用いて、図1及び2に示すように、クッション材15の平坦部から凸部16が鍔14外縁に沿って一周して突き出ており鍔14に一体成型されるようにキャップ本体11である天板12、外筒スカート部13、及び鍔14とクッション材15とから成る緩み防止キャップ10を射出成型で形成し、一方、容器本体20をブロー成型で形成して、液体容器1を作製した。
緩み防止キャップの試作の際に、表1の各樹脂を用い、表2の各部位・部材の材質・形状規格にしたこと以外は、実施例1〜6と同様にして、本発明を適用外の比較例1〜6のキャップを作製し、液体容器の性能を評価した。その結果を、表2にまとめて示す。
クッション材の素材を表3に記載のものに変え、凸部の形状を表3の通りにしたこと以外は、実施例1〜6と同様にして、本発明を適用する実施例7〜14の緩み防止キャップと、本発明を適用外の比較例7のキャップを作製し、液体容器の性能を評価した。その結果を、表3にまとめて示す。
