    摘要: A preform configured to form a container by stretch blow molding. A finish portion is at a first end of the preform, and is a container finish. A tip portion is at a second end of the preform opposite to the first end, and is configured to form a container base and a container heel. The shoulder portion is adjacent to the finish portion and is between the finish portion and the tip portion. The shoulder portion is configured to form a container shoulder. The body portion is between the shoulder portion and the tip portion, and is configured to form a container body. The outer surface includes a first flat portion and a second flat portion at the tip portion. The first flat portion extends at a first angle and the second flat portion extends at a second angle that is different than the first angle.

    摘要: The invention relates to a new PET preform design that enables a more precise distribution of material in the bottle bottom and avoids the waste of material around the injection point. The thickness BWTmin of the wall at the center of the gate or tip (3) (injection point) is reduced to a minimum in order to avoid the waste of material around the injection point when the preform is blown. This is particular important for carbonated soft drink application since the reduced amount of amorphous material at the center of the gate (3) helps to reduce the risk of stress cracking on the bottle base. Furthermore a step (4) having thickness WTmax in the body wall thickness, in the region of the periphery of the base with WTmax>WT, allows enough material to be available for the proper blowing of the bottle bottom making the bottle more stable.
