Abstract
【解決手段】内容物の充填空間を有しその先端に注出ノズルを装着したシリンジ本体1と、押し込み力の付加によりシリンジ本体1内にてスライドさせて該充填空間m内の内容物を注出ノズルの先端より注出するプランジャー2と、このプランジャー2の先端部分に形成された環状溝部2cに設置され、シリンジ本体1の内壁面に沿い摺動可能なOリング3とを備えたディスペンサーにおいて、前記環状溝部2cを、その全域にわたってフラットな底壁を有する区画凹所とする。そして、該環状溝部2cの側壁に、該プランジャー2の押し込みにしたがって該Oリング3の側部を当接、弾性変位、さらには圧縮変形させる一方、該プランジャー2の押し込みにかかる負荷を解除してその復元力にてプランジャー2を押し込み方向とは逆向きにスライドさせて内容物のバックサクションを誘導する凸部又は溝4を設ける。
【選択図】図1
Description
