Abstract
A liquid storage container has a double structure provided with an outer container forming an outer shell and a liner arranged in the outer container, the liner accommodating a liquid, wherein the liquid is pushed out from the liner by gas pressure introduced into the outer container so as to flow out to an exterior of the container from a siphon of a plug attached to a stopper portion of the outer container, a substantially concentric drop tube is arranged on an outer periphery of the siphon so as to form a space portion serving as a liquid flow passage, a through hole is formed on a tube wall of the drop tube, and an outlet opening for making the inflow liquid coming from the through hole flow out from the liquid flow passage.
