Abstract
A plastic vessel preform includes a neck portion having an outer layer formed by an insert piece (20) which includes a thread portion (22a) and a support ring (28). The support ring (28) includes a bond reinforcing portion (36) integrally formed therein in a direction perpendicular to the axis or the preform body (34). The bond reinforcing portion (36) strengthens the radial bond in the insert piece (20) so that the mechanical strength at the neck portion (32) of the preform (30) can be greatly increased.
