PROBLEM TO BE SOLVED: To provide an improved I.S. machine which can improve the trajectory of a gob without the use of a funnel mechanism. SOLUTION: The blank mold for the I.S. Machine is made up of a pair of opposed engaged blanks 10. The blanks 10 have a top surface 36 with an opening when closed. The blanks have an inner surface defining the side wall of a parison which extends upwardly to a position of 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 to the top opening of the blanks. A pair of funnels, each having a continuous beveled surface extending from a circular horizontally disposed top opening 61 downwardly to smaller centrally located bottom opening 56, are engaged with the top of the blanks with the top opening of the blanks and the bottom opening of the funnel being coextensive.
