Patent ID: 7721402

Claim:
A method for producing a tip unit for a liquid applicator, the tip unit having a central axis, wherein the tip unit comprises a tip body having a ball housing and a ball, the ball housing having an opening at a distal end of the tip body and holding the ball therein, the method comprising: a first process of shaping the contour of the tip body in the form of a truncated conical surface; a second process of forming the ball housing in the tip body; a third process of placing the ball into the ball housing; a fourth process of scraping the peripheral side of the distal end portion of the tip body after the first process to thereby make the distal end portion of the tip body radially thinner where the distal end portion of the tip body is scraped; and a fifth process of deforming the peripherally scraped distal end portion of the tip body toward the ball.
