ABSTRACT:
An applicator constructed such that when the user clicks a rear end of an inner barrel, a valve mechanism is actuated by moving the inner barrel relative to an outer barrel, whereby an application liquid is supplied to an applying element arranged at a front end part of the outer barrel, and that when a valve seat member and a valve rod member move relatively to each other, the valve mechanism can take a first state in which a piston portion on the front side of the valve rod member comes into sliding contact with a front-side liquid-tight portion inside the valve seat member, a second state in which both of the piston portion on the front side of the valve rod member and piston portion on the rear side of valve rod member do not come in sliding contact with the corresponding liquid-tight portions inside the valve seat member, and a third state in which the piston portion on the rear side of the valve rod member comes into sliding contact with the rear-side liquid-tight portion.
