ABSTRACT:
A method of injection molding a container having a body and an upper opening surrounding a neck of a container produces a container in which a diameter of the body is greater than the diameter of the neck. The method includes injecting plastic or other appropriate material into a cavity of the mold assembly and, after the container material has cooled sufficiently to retain its shape, sequentially removing portions of the mold assembly from the container.
