<p>A liquid feeding and dispensing apparatus having a disposable whole liquid container unit that can be immersed in a sterilizing tank for cleaning. The liquid container unit has an elastic liquid container (1), a pump (2), and valves (3,4) integrated therein that is separate from a holder unit (B) for driving a pump. The liquid container unit has an expansible liquid container filled with a liquid, a liquid feeder (1a) connected with an outlet from the liquid container at one end, and a pump chamber (5) having one end connected with the other end of the liquid feeder. The pump chamber has a flexible wall plate (2a), and a feeding tube (9) connects with an outlet end of the pump chamber. A pump holder unit has a pump drive body (6) detachably holding the pump chamber for deviating or flexing the flexible wall plate to change the volume of the pump chamber. A pinch valve (11) has a groove for inserting and receiving the feeding tube to pinch the feeding tube closed when not feeding the liquid. In an alternate embodiment the pump chamber is sealed by a projection on the inside of the flexible wall plate. <IMAGE></p> |
