| Zusammenfassung: | A blank mold for an I. S. machine is made up of a pair of opposed engageable blanks (10). When closed, these blanks (10) have a top surface (36) with an opening (58). The blanks have an inner surface (20) defining the side wall of a parison, which extends upwardly to a position a defined distance below the top surface (36) of the blanks, and a continuous, beveled surface (30) connecting the top of the inner surface defining the side wall of the parison and the top opening (58) of the blanks. A pair of funnel segments (50), each having a continuous beveled surface (60) extending from a circular horizontally disposed top opening downwardly to smaller centrally located bottom opening (56), are interfit with the top of the blanks (10) with the top opening (58) of the blanks and the bottom opening (56) of the funnel segments (50) being coextensive. |
