Claim Text:
1. A click-type applicator storing an application liquid in a barrel cylinder, wherein a screw shaft is engaged with the rear part of a piston that slides inside the barrel cylinder, the piston is advanced by means of the screw shaft by a propelling operation on a propelling mechanism so as to supply the application liquid inside the barrel cylinder to an applying part at the front end of the barrel cylinder, wherein the propelling mechanism comprises: a rotary cam element having cam portions formed in the front and rear thereof; a transfer cam element having a cam portion at the front thereof to mesh the cam portion at the rear of the rotary cam element and having a projected part formed on the side surface thereof; a propelling element, in which a guide slot that guides the projected part of the transfer cam element is formed inclined relative to the axial direction, and which is restrained from rotating relative to the barrel cylinder; a spring that urges the propelling element backwards and urges the transfer cam element forwards; and, a fixed cam element formed with a backward-facing cam portion and restrained from rotating relative to the barrel cylinder, one of the rotary cam element and the fixed cam element is formed with an engagement structure that is restrained from rotating relative to the screw shaft while the other is formed with a threaded part that mates with the screw shaft so that rotation of the rotary cam element is transformed into a motion that advances the screw shaft relative to the barrel cylinder by the function of cooperation of the engagement structure, the threaded part and the screw shaft, so as to advance the piston, when the propelling element is moved forwards by a clicking operation, the advancing motion is transformed into a rotary motion of the transfer cam element in one direction by the function of the guide slot and projected part so that when the cam portion of the transfer cam element meshes with the cam portion at the rear of the rotary cam element, the rotation of the transfer cam element causes the rotary cam element to rotate and thereby move the screw shaft and hence the piston forwards, when the clicking operation is released after the propelling element has been once advanced by the clicking operation, the propelling element moves backwards due to the repulsive force of the spring, and the backward motion of the propelling element is transformed into a rotary motion of the transfer cam element in the other direction by the function of the guide slot and the projected part so as to restore the original position while the cam portion at the front of the rotary cam element meshes with the cam portion of the fixed cam element, whereby the rotary motion of the rotary cam element is restrained and hence the operational actions of the screw shaft and the piston are restrained, the fixed cam element has a sleeve portion that extends backwards, and the propelling mechanism is configured to arrange the rotary cam element, the transfer cam element, the propelling element and the spring within the sleeve portion of the fixed cam element, the fixed cam element having the sleeve portion is formed as a single piece, the backward-facing cam portion is formed annularly, the backward-facing cam portion is configured in such a manner that the backward-facing cam portion does not move relative to the fixed cam element, and the application liquid is a high-viscosity cosmetic fluid.
