    摘要: In forming containers from injection molded preforms of thermoplastic material such as nitrile-based polymers by a process which includes heating the preforms to orientation temperature followed by distension to container form in a mold, the improvement providing reduced thickness variability in lower portions of the containers which involves controlling preform shrinkage during such heating to between about 4 to 15% of the initial length for nitrile materials by maintaining the ratio of average thickness to inside preform surface area within defined limits and then axially and radially stretching such preforms during distension to predetermined levels. Nitrile preforms convertible to such improved quality containers have values of between about 0.005 to 0.011 inch.sup.-1 for the aforementioned ratio.

    摘要: In a blow-molding machine, a blow head assembly which includes a housing having valve means therein for rapidly exhausting the blowing gas from the mold cavity after formation of the article without withdrawing the assembly from registry with the mold opening. The assembly also may include a recessed blow head to facilitate removing the blown article from the mold. Use of the blow head involves establishing a seal therein with an end portion of the parison during blowing which is broken by the opening movement of the mold sections to permit the article to fall cleanly away from the mold.

    摘要: Conditioning station tooling for adjusting a temperature of a preform. The tooling comprises a mold presenting a cavity configured to receive at least a portion of the preform. The mold is configured to receive the preform such that a gap is present between the mold and the preform. The mold includes an air inlet and an air outlet. The tooling is configured to permit air to be injected from the air inlet, through the gap between the mold and preform, and out of the air outlet. The tooling further comprises a core configured to be received within an interior of the preform and to contact an interior surface of the preform.
