Claims

[Claims for Utility Model Registration] (1) Formed as a box-like body with an open top;
A process in which a liquid is introduced from the bottom of the tank to perform a specified treatment on the object being charged through the top opening, and the processing liquid in the tank is continuously replaced while overflowing from the upper edge of the tank wall. A tank, in which a large number of means for discharging the processing liquid from inside the tank are installed below the upper edge of the tank wall and distributed almost uniformly around the upper edge of the tank wall. An overflow type processing tank characterized in that the processing liquid is replaced while the processing liquid is discharged outside the tank using at least a large part of the discharge capacity of the discharge means. (2) Utility Model Registration The overflow type processing tank according to claim 1, characterized in that the discharge means is a concave and convex portion continuous with the upper edge of the tank wall. (3) An overflow type treatment tank according to claim 1, wherein the discharge means is a slit cut from the upper edge of the tank wall. (4) Utility Model Registration The overflow type treatment tank according to claim 1, characterized in that the hole is formed below the upper edge of the tank wall of the discharge means.
