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.
