Abstract
A tank includes a tank portion with an opening formed at a flat surface which serves as a bottom portion when in use, and a liquid dispensing member having a cylindrical shape and protruding outward from the tank portion at a right angle to the flat surface from the opening with its tip end portion cut diagonally with respect to the central axis of the cylinder. As a result, even a cleaning liquid having high surface tension such as water can be dropped out through the liquid dispensing opening.
