<p>PURPOSE:To exclude the labor and time that are otherwise required to eliminate scraped resin material from the inside of an apparatus, to make the apparatus simple and to facilitate the operation, by molding a head reaction sheet to have the head section sheet from with an opening, and molding the head section sheet into a surface part of a tubular container. CONSTITUTION:A head section sheet HS that has been punched to has an opening S2 at the central section is welded integrally to one end of a sleeve 14, and the sleeve 14 and the head section sheet HS are introduced in a core mold 9 and a cavity mold 12 for cooperatively molding a tubular container. With a mouth core section 11 projected from the forward surface of a mouth cylindrical core 10 formed at the forward end of the core mold 9 inserted into the opening S2 of the head section sheet HS, the head material sheet HS is compression molded into a head H of a tubular container T by the core mold 9 and the cavity mold 12. Therefore, since scrap of the resin material would not be generated at the mold apparatus section, the operation and time for removing such scrap out of the mold apparatus are not required.</p> |
