PROBLEM TO BE SOLVED: To automatically finish drip and to avoid that a large amt. of air enters an instillator and to make the instillator repeatedly usable without troublesome work. SOLUTION: A floating body 7 with a smaller specific gravity than that of water is stored freely movably up and down in a drip cylinder 2 in the midway of a tube 1. The floating body may be constituted of a floating part and a blocking part. Thereby, as replenisher 11 is little left and the face of the replenisher 11 in the drip cylinder 2 is lowered, the floating body 7 also descends to block a feeding hole. It is possible thereby to automatically finish drip and to avoid that air any more enters an installator and to make the instillator repeatedly usable. |
