Lightweight plastic container and preform

A method for injection molding a plastic preform, the plastic preform comprising:

• a hollow body portion, comprising:
• a closed bottom portion;
• and
• a lower portion extending upwardly from the closed bottom portion;
• and
• a neck portion extending upwardly from the lower portion, the neck portion including:
• a dispensing opening positioned at a top of the neck portion;
• threads positioned below the dispensing opening;
• a tamper-evident formation positioned below the threads, the tamper-evident formation having a lower surface;
• and
• a support flange positioned below the tamper-evident formation, the support flange having an upper surface and a lower surface;
• wherein the plastic preform is formed of a material comprising polyethylene terephthalate (PET);
• a vertical distance from the lower surface of the support flange to the top of the neck portion is from 0.425 to 0.500 inches;
• and an outside diameter of the support flange is greater than 22 mm and less than or equal to 39.2 mm.
