A liquid discharge apparatus has a tubular casing having an applicator at one end and an actuator button with a pressing portion at the other end. A thin wall resilient portion is integrally connected between the tubular casing and the pressing portion so that the pressing portion can be moved axially within the tubular casing. The tubular casing has a liquid chamber therewithin between the actuator button and the applicator tip, and a valve is provided having a valve body connected to the actuator button so that the valve body is movable by actuation of the actuator button. A liquid storage chamber having a recess at a rear end receives the valve body therein, the storage member being connected to a rear end of the applicator tip. A liquid discharge restriction chamber has a tube portion fitted into the recess of the liquid storage member and the tube portion has a valve seat which is resiliently engageable by the valve body.
