ABSTRACT:
A cup rinse with a valvular ring according to the invention is disclosed. The valvular ring has a plurality of valves in the center thereof. When an inlet tube is inserted through the valvular ring, the valves are forced to open thereby to allow a chemical liquid to flow into the cup resin via the inlet tube. Inversely when the inlet tube is completely pulled out of the valvular ring, the valves are tightly closed without a chemical liquid leakage. Accordingly, the cup rinse of the invention can prevent peripheral precision instruments, such as a motor, from damage by a leaky chemical liquid. Thus, the cup rinse of the invention cannot cause any unnecessary cost consumption.
