【０００２】
【従来の技術】
容器体装着用の液体噴出ポンプとして、シリンダを容器体内へ垂下する縦形のポンプと、トリガー式のポンプとが広く知られており、それ等はいずれも容器体底部まで吸上げパイプを垂下し、ポンプ操作により容器体内液体をシリンダ内へ吸上げ、かつ該シリンダ内をノズルから噴出するよう設けている。
【０００３】
【発明が解決しようとする課題】
上記ポンプは、当初容器体に装着されてポンプ付きの容器として用いられていたが、近時廃棄物の減少、又資源活用の見地からポンプを有しない、いわゆるレフィール用の容器体を設けて当初使用したポンプを、ポンプを有しない予備の容器体に再装着してそのポンプを複数の容器体に付け替えして何回も使用することが行われるようになった。このように１箇のポンプを何回も他の容器体に付け替えて使用すると、容器体内液体中に含まれている微小な浮遊物や、薬液等成分の結晶体、又ポンプ交換の際に容器体内へ入った埃等がポンプ内に蓄積されて目塞り等故障の原因となる。特に泡噴出用ポンプの場合は噴出液体を発泡させるため、液体流出路の要所に約200 メッシュ程度のネットを用いるから、その網目が目塞りするおそれが大となり、そのネットに付着した浮遊物等の除去が困難となる。
【０００４】
本発明は上記吸上げパイプ下端部に、ポンプ交換の際に邪魔とならず、又付着物の除去が容易なフィルターを設けることで、上記ポンプを複数の容器体に対して何回も使用可能としたものである。
【０００５】
