Abstract
A container for liquid, which discharges contents when the side surfaces thereof are pressed by the fingers. A coupling unit is assembled to the top of the container body so as to discharge the pressed contents. The coupling unit has an outlet comprising a check valve which opens/shuts by means of predetermined pressure. The coupling unit having the outlet is covered with a lid for protecting the outlet. The side surfaces of the container body have pressure adjustment surfaces that protrude inwardly. Predetermined gaps are maintained between the ends of the pressure adjustment surfaces and the side surfaces of the container body, located in front of the ends of the pressure adjustment surfaces.
