PURPOSE:To automatically measure various kinds of liquid and easily discharge them from a container in simple and inexpensive constitution by arranging a compact measuring pump in the discharge section of the container for liquid and constituting this pump of an elastic hollow body, a pair of check valves and vibration driving means. CONSTITUTION:A vibration drive type measuring discharge pump 20 driven by a pump vibration driving means 10 is attached to the liquid discharging port of a bag B1 for liquid, which is contained in a bag containing section C to constitute a bag B for liquid with a compact measuring discharge pump. In this case, a piezo electric element 10a is arranged to the pump vibration driving means 10. On the other hand, the vibration drive type measuring discharge pump 20 is provided with a pump nozzle section 22 comprising an elastic hollow diaphragm mainly. The pump nozzle section 22 is provided with a pair of check valves 23 and 24. Between the means 10 and pump 20, fitting sections 11 and 25 and diaphragm 26 are arranged. By this constitution, various kinds of liquid can be automatically measured and easily discharged in simple and inexpensive constitution. |
