Abstract
Description
前記胴部を押圧して充填した内容液を吐出させる場合において、
前記内層体に充填した内容液を吐出させる前の初期充填量に対する累積での吐出量の割合が45〜60%である間、該胴部への押圧力は30〜45Nであり、
且つ、累積での吐出量の割合が60%である際に復元した前記外層体の偏平度は0〜0.15である二重容器である。
前記胴部の内側への変位量が0〜10mmである間、該変位量に対する該胴部への押圧力の変化率は0.6〜1.2N/mmであることが好ましい。

- ボトル状に形成され可撓性を有する外層体と、該外層体の内側に設けられ内容液が充填される内層体とを備え、該外層体の胴部を内側に押圧することによって該内層体を減容変形させつつ内容液を吐出させることが可能な二重容器であって、
前記胴部を押圧して充填した内容液を吐出させる場合において、
前記内層体に充填した内容液を吐出させる前の初期充填量に対する累積での吐出量の割合が45〜60%である間、該胴部への押圧力は30〜45Nであり、
且つ、累積での吐出量の割合が60%である際に復元した前記外層体の偏平度は0〜0.15である二重容器。 - 前記内層体に内容液を充填する前の状態において前記胴部を押圧する際、
前記胴部の内側への変位量が0〜10mmである間、該変位量に対する該胴部への押圧力の変化率は0.6〜1.2N/mmである請求項1に記載の二重容器。 - 前記外層体は、ポリエチレンテレフタレート樹脂(PET)で形成される請求項1又は2に記載の二重容器。
