Abstract
【解決手段】 液体混注具Aを、液体混注具本体10と操作部20とで構成した。そして、液体混注具本体10を、円筒状に形成されたチャンバー部11と、チャンバー部11の軸方向の一方に形成された合流分岐管12と、チャンバー部11の外周面両側に形成された下流分岐管13および上流分岐管14とで構成した。また、操作部20を、弁体21と把持部22とで構成し、弁体21がチャンバー部11の内部側に位置したときに上流分岐管14とチャンバー部11との間が遮断され、弁体21がチャンバー部11の外部側に位置したときに上流分岐管14とチャンバー部11との間が連通するようにした。また、ガイド突起19とガイド溝25とのスライド係合によって操作部20を移動可能にした。
【選択図】 図1
Description
以下、本発明に係る液体混注具を図面を用いて詳しく説明する。図1および図2は、本発明の第1実施形態に係る液体混注具Aを示しており、この液体混注具Aは、液体混注具本体10と、操作部20とで構成されている。液体混注具本体10は、軸方向の長さが短い円筒状のチャンバー部11と、チャンバー部11の軸方向に沿った一方(図1および図2の上方)に形成された合流分岐管12と、チャンバー部11の外周面における両側に180度の角度を保って同軸に沿って延びるように連結された一対の下流分岐管13および上流分岐管14とで構成されている。
図12および図13は、本発明の第2実施形態に係る液体混注具Bを示している。この液体混注具Bは、液体混注具本体30と操作部40とで構成されており、内部が、図14ないし図18に示したように構成されている。すなわち、チャンバー部31の上方に形成された合流分岐管32は、チャンバー部31と別体からなる部材で構成されており、チャンバー部31側の直径が大きく上方に行くほど直径が小さくなった先細り状の円筒体で構成されている。また、この合流分岐管32は、平面視による形状が楕円形に形成されている。
