Method of producing applicator tip

摘要

A method for producing a tip unit ( 1 ) for a liquid applicator in a stable and easy process, the tip unit ( 1 ) being capable of increasing the rate of liquid discharge is provided. The method includes at least five processes; that is, a first process of shaping the contour of a tip body ( 11 ) in the form of a truncated conical surface; a second process of forming a ball housing ( 15 ) having an open end at its distal end in the tip body ( 11 ); a third process of placing a ball ( 10 ) into the ball housing ( 15 ); a fourth process of scraping the peripheral side of the distal end portion of the tip body ( 11 ) to form a peripherally scraped portion ( 55 ) after the first process; and a fifth process of deforming the peripherally scraped distal end portion of the tip body ( 11 ) toward the ball ( 10 ).
