摘要

The tank has a pair of openings (1c) at base of an inner wall (1b) of a container (1), and a capillary core (4) passing through the openings. An opening (1d) on an upper part of a water compartment fills dimensioned base and lateral walls of the compartment so that water exerts a permanent natural pressure on ends (4a) of the core. Base of an outer wall of the container has a discharge opening (1e) closed by a stopper.
