The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of making a preform by molding, the molding steps comprising:
introducing a first thermoplastic material into a first mold to form during a first molding step while under first molding conditions a substantially crystallized first portion of a preform in the first mold, wherein the first molding conditions include a first melt temperature selected for achieving crystallization of the first thermoplastic material;
transferring the first portion of the preform to a second mold; and
introducing a second thermoplastic material into the second mold to form by a second molding step while under second molding conditions different from the first molding conditions a substantially amorphous second portion of the preform and maintaining compressive forces to bond the first and second portions.
2. The method of claim 1, wherein the first mold is heated to enable crystallization of the first material and the second mold is cooled to enable solidification and removal of the first and second preform portions from the second mold.
3. The method of any one of claim 1, wherein one or more differences in temperature and pressure are used in the first and second molds to obtain the different first and second molding conditions.
4. The method of any one of claim 1, wherein the first preform portion is opaque.
5. The method of claim 4, wherein the second preform portion is transparent.
6. The method of any one of claim 1, wherein the first mold is heated to enable crystallization of the first thermoplastic material.
7. The method of claim 6, wherein the second mold is cooled to enable solidification and removal of the preform from the second mold.
8. The method of any one of claim 1, wherein the average percent crystallinity of the first preform portion in the first mold is at least 30%.
9. The method of claim 8, wherein the average percent crystallinity of the first preform portion in the first mold is at least 35%.
10. The method of claim 8, wherein the average percent crystallinity of the first preform portion in the first mold is at least 40%.
11. The method of any one of claim 1, wherein the second thermoplastic material has a relatively low crystallization rate compared to the first thermoplastic material.
12. The method of any one of claim 1, wherein the first mold is at a higher temperature than the second mold.
13. The method of any one of claim 1, wherein the first preform portion is substantially a neck finish portion.
14. The method of claim 13, wherein the second preform portion is substantially a body-forming portion.
15. The method of any one of claim 1, wherein during the first molding step a first molding core is positioned in the first mold for forming the first preform portion on the first core, and the first core and first preform portion are transferred to the second mold for forming the second preform portion over the first core in the second mold.
16. The method of claim 15, wherein during the first molding step a second core with a first preform portion is positioned in the second mold for simultaneously molding a second preform portion on the second core.
17. The method of any one of claim 1, wherein during the first molding step a plurality of first preform portions are molded on a plurality of first cores in a plurality of first molds, and during the second molding step a plurality of second preform portions are molded on the plurality of first cores in a plurality of second molds.
18. The method of claim 17, wherein during the first molding step a plurality of second cores with first preform portions are positioned in the second molds for simultaneously molding a plurality of second preform portions on the second cores.
19. The method of any one of claim 1, wherein a flow adjusting element is provided in the second mold to increase the flow rate of the second thermoplastic material adjacent the first thermoplastic material.
20. The method of any one of claim 1, wherein the second thermoplastic material comprises a polymer composition and the first thermoplastic material comprises the polymer composition with nucleating agents to increase the crystallization rate.
21. The method of claim 20, wherein the polymer composition is a polyester composition.
22. The method of claim 21, wherein the polyester composition is substantially polyethylene terephthalate (PET).
23. The method of any one of claim 1, wherein the first thermoplastic material is selected from the group consisting of polyester, polyester with nucleating agents, arylate polymers, polyethylene naphthalate (PEN), polycarbonate, polypropylene, polyimide, polysulfone, and acrylonitrile styrene.
24. The method of claim 23, wherein the second thermoplastic material is selected from the group consisting of homopolymers, copolymers and blends of any one or more: polyethylene terephthalate (PET), polyethylene napthalate (PEN), and post-consumer PET.
25. The method of any one of claim 1, further comprising introducing a non-thermoplastic material into at least one of the first and second molds to form a non-thermoplastic layer in at least one of the first and second preform portions.
26. The method of any one of claim 1, further comprising expanding the second preform portion to form a container having a substantially transparent second portion and the crystallized first portion.
27. The method of any one of claim 1, wherein the first portion is a neck finish portion and the second portion is a body-forming portion.
