摘要

The preform for the produu00c7u00e7o plastic bottles, bottle of plastic material, and process for produu00c7u00e7o a bottle of plastic material in a stretching process by blowing a preform are described as well as a process for the production of plastic bottles, in particular PET bottles. Which has a rigid body (2), a substantially elongated.It has a bottom (5) in one of its ends elongated.In its elongated end opposite the body (2) of the preform (1) is adjacent to a section of the neck (3) equipped with an opening of the leak (6), said section of the neck (3) which is separated from the body (2) by a support ring (4) of the type of flange. That protrudes radially, and below the ring. Support (4) has an inclination of the preform (a).The preform (1) has an external diameter of 17.4 mm - 21.4 mm, measured in the transition of the body (2) to the bottom (5), and from there to a wall thickness of 3.4 mm to 4.4 mm. Still, the preform (1) presents in the slope of the preform (a) a wall thickness of 1.4 mm to 2.2 mm.The external diameter of the inclination of the preform (a) is dimensioned in such a way that he presents, with the preform (1) is introduced in the form of breath (10), a distance (d) in relation to the wall of the blow moulding (12) queu00e9de mm to 3 mm.
