<p>Disclosed is a liquid applicator vessel, the cost of which is reduced while maintaining the same impression from use as current products by decreasing the number of parts while maintaining the quality demanded from a rotary applicator vessel, and enabling assembly using a simple method. In the liquid applicator vessel, sealing sections (18a, 18a) formed on the outer circumference of the front section of a piston (18) make sliding contact with the inner wall of an enclosed section (12) of a main shaft (10), and additionally a tubular portion (18b) is formed having a female screw section (38) on the inner circumference and a pair of protrusions (36) configured from rib-shaped protrusions protruding radially outward from the outer circumference of the back section of the piston (18). A male screw section (40) which is threaded with the female screw section (38) of the aforementioned tubular portion (18b) is formed on the outer circumferential surface of the front section extending forward from the operating section (16a) of a rotating body (16). The space of the enclosed section (12) is formed towards the front of the aforementioned main shaft (10), and towards the back, grooves (42) which engage the protrusions (36) of the aforementioned tubular portion (18b) are formed along the axial direction.</p> |
