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.

Process for the production of oriented hollow bodies

A hollow container made of thermoplastic material, having its base connected to its side wall by an integral, peripheral rounded molding, and having its base formed of at least two substantially planar, axially staggered, concentric annular zones connected together by alternating molded portions of rounded cross section.

Hollow body of thermoplastic material

A hollow article made of an oriented thermoplastic having improved resistance to lateral impact, and provided with a base composed, successively, of a peripheral arched profile, a substantially plane annular zone and a recessed central part in the shape of a dome, the diameter of the central part being less than 40% of the maximum diameter of the hollow article. Such a hollow article is particularly suitable for the packaging of beverages.

Hollow article made of an oriented thermoplastic

A process for the production of hollow articles from preforms of a thermoplastic material, one open end of which preforms has a neck moulded at least partially into its definitive shape. During the final blowing operation, the region corresponding to the moulded part of the preform is isolated from the remainder of the interior of the preform. The isolated region is cooled by sweeping with a cooling fluid.
