Embodiments of the present invention teach a post-mold treatment device and post-mold preform receptacle for use therewith for a post-mold treatment of a preform having a bell-shape. More particularly, an upper portion of a receptacle cavity associated with the post-mold preform receptacle is configured to have the same shape as the transition portion of the preform, and the upper portion is further configured to have a transition-fit size with respect to the transition portion of the preform at the instant that the preform is received from the molding cavity of the injection mold.

A post-mold preform receptacle (110) for treatment of a preform (6) received therein in accordance with a balanced cooling rate post-mold treatment process, the preform (6) having a bell-shape that includes a transition portion (8) connecting a neck finish portion (9) with a body portion (4), the post-mold preform receptacle (110) comprising:
- a body (113) that defines a receptacle cavity (112) for accepting, in use, the transition portion (8) and the body portion (4) of the preform (6);
- a lower portion (14) of the receptacle cavity (112) being configured to have the same shape as the body portion (4) of the preform (6), and the lower portion (14) being further configured to have a body-interference size (I) with respect to the body portion (4) of the preform (6) at an instant that the preform (6) is received from a molding cavity of an injection mold;
- an upper portion (116) of the receptacle cavity (112) being configured to have the same shape as the transition portion (8) of the preform (6), and the upper portion (116) being further configured to have a transition-fit size (F) with respect to the transition portion (8) of the preform (6) at the same instant that the preform (6) is received from the molding cavity of the injection mold whereby there is contact between the transition portion (8) and the upper portion (116).
