Abstract (en)
[origin: US4317793A] A process for producing molecularly oriented hollow bodies of thermoplastic material presenting an accurately dimensioned orifice collar, by blow molding a preform in a manner to produce the orifice collar in its definitive form and, after thermally conditioning the preform, finally blow molding the desired final hollow body while forming the lower molded part of the neck below the orifice collar. This process permits the production of oriented hollow bodies with which a closure member can form an effective seal, and which can therefore be used for packaging carbonated beverages.
