A blank mold for an I. S. Machine is made up of a pair of opposed engaged blanks. When closed, these blanks have a top surface with an opening. The blanks have an inner surface defining the side wall of a parison which extends upwardly to a position a defined distance below the top surface of the blanks and a continuous, beveled surface connecting the top of the inner surface defining the side wall of the parison and the top opening of the blanks. A pair of funnels, each having a continuous beveled surface extending from a circular horizontally disposed top opening downwardly to smaller centrally located bottom opening, are interfit with the top of the blanks with the top opening of the blanks and the bottom opening of the funnel being coextensive.
