Method of producing applicator tip

Abstract

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).
