ABSTRACT:
A cup-shaped closing material having a convex section is fitted on a protrusion-like engagement section of a distal end of a mandrel with a gap from the engagement section of the mandrel, a molten resin is then disposed in a cavity of a molding die and a holepin having an outer peripheral section of a distal end that is smaller than an outer periphery of the distal end surface of the convex section of the closing material is pressed against the distal end surface of the convex section of the closing material, whereby the distal end surface of the convex section of the closing material is pleated to form an annular protrusion section at the outer peripheral section, and the molten resin is caused to envelope the annular protrusion section, while being pushed and charged into the cavity, whereby the head part with the closing material attached thereto is formed.
