A blow molded synthetic resin bottle has a body and an elongated neck with the body providing a shoulder extending about the base of the neck. The neck has a first collar extending thereabout spaced adjacent the shoulder and at least one additional collar extending thereabout adjacent the upper end of the neck. The resin in the neck is substantially unoriented. To produce the bottle, a synthetic resin preform is injection molded with a generally tubular body and the elongated neck. This preform is placed in a blow mold cavity having a body receiving portion and a neck receiving portion that has a recess extending thereabout seating the first collar therein. The additional collar is disposed outwardly of the mold cavity and is disposed on the upper surface of the mold.

1. A method for making a container, the method comprising: providing a molded, plastic preform including a closed body, a neck located between the closed body and an open end, and a first and second collar and thread formation located along the neck, wherein the thread formation is located between the open end and the first collar;providing a mold having a body receiving portion and a neck receiving portion, wherein the neck receiving portion includes a circumferential recess;closing the mold about the preform so that the closed body of the preform is received within the body receiving portion of the closed mold, the first collar of the preform is seated within the circumferential recess of the neck receiving portion of the closed mold, the thread formation is located outside of the neck receiving portion and the closed mold, the second collar is seated on an uppermost surface of the closed mold, and a portion of the neck between the first collar and the thread formation is located within and encircled by the neck receiving portion of the closed mold; andinflating only the closed body of the preform into conformity with walls of the body receiving portion of the closed mold. 2. The method of claim 1 further comprising heating the preform prior to said closing. 3. The method of claim 2, wherein the preform is rotated about a longitudinal axis of the preform during said heating of the preform. 4. The method of claim 1, wherein the second collar is axially spaced from the first collar, a portion of the neck of the preform between the first collar and the second collar is located within the neck receiving portion of the closed mold, and an interior of the neck receiving portion of the closed mold, including the circumferential recess, conforms to the first collar and to the portion of the neck of the preform between the first collar and second collar that extends within the neck receiving portion of the mold. 5. The method of claim 1, wherein more than half of an axial length of the neck is located within the neck receiving portion of the mold following said closing of the mold. 6. The method of claim 1, wherein the open end of the preform has a diameter and an axial length of the neck of the preform is greater than the diameter of the open end. 7. The method of claim 1 further comprising engaging the preform between the thread formation and the first collar with a gripper to move the preform into the mold. 8. The method of claim 7, wherein the preform is held by the gripper during said closing of the mold. 9. The method of claim 8, wherein the gripper contacts an outer surface of the mold during said closing. 10. The method of claim 1 further comprising injection molding the preform. 11. The method of claim 1, further comprising inserting a spindle into the open end of the preform and rotating the preform with the spindle. 12. The method of claim 1, wherein the second collar has a smaller diameter than the first collar. 13. A method for making a container, the method comprising: providing a preform having a body, a neck located between the body and an open end, and an upper and lower collar located between the open end and the body;providing a mold having a body receiving portion and a neck receiving portion, wherein the neck receiving portion includes a recess;heating the body of the preform;closing the mold about the preform following said heating of the preform such that the body of the preform is received within the body receiving portion of the closed mold, the lower collar of the preform is seated on a bottom of the recess within the neck receiving portion of the closed mold, a portion of the neck between the lower collar and the open end is located within and encircled by the neck receiving portion of the closed mold, the upper collar contacts an uppermost surface of the closed mold, and a portion of the preform neck extends outside of the neck receiving portion and the closed mold; andblowing only the body of the preform into conformity with walls of the body receiving portion of the mold to form a bottle. 14. The method of claim 13, wherein the upper collar is located between the open end and the lower collar, and the neck receiving portion of the closed mold conforms to the lower collar. 15. The method of claim 13, wherein the upper collar is axially spaced from the lower collar, and a portion of the neck of the preform between the lower collar and the upper collar is located within the neck receiving portion of the closed mold. 16. The method of claim 15, wherein more than half of an axial length of the neck is located within the neck receiving portion of the closed mold. 17. The method of claim 15, wherein the preform further comprises a thread formation located between the open end and the upper collar. 18. The method of claim 14 further comprising engaging the preform between the upper collar and the lower collar with a gripper to move the preform into the mold. 19. The method of claim 18, wherein the preform is rotated about a longitudinal axis of the preform during said heating of the preform, said rotating conducted by a spindle inserted into the open end of the preform. 20. The method of claim 18, wherein the gripper contacts an outer surface of the mold when the preform is moved into the mold. 21. The method of claim 13, further comprising rotating the preform about a longitudinal axis of the preform during said heating of the preform. 22. The method of claim 13, wherein the neck of the preform includes a thread formation. 23. A method for making a container from a preform, the method comprising: providing a preform;providing a mold having a body receiving portion and a neck receiving portion, wherein the neck receiving portion includes a circumferential recess and a neck cavity section;closing the mold about the preform such that a closed body of the preform is received within the body receiving portion of the closed mold, a collar located around a neck of the preform is seated on a bottom of the circumferential recess within the neck receiving portion of the closed mold, a thread formation of the preform is located outside of the neck receiving portion and the closed mold, a portion of the preform between the collar and the thread formation contacts and sits on an uppermost surface of the closed mold, and a portion of the neck of the preform between the collar and the thread formation is located within and encircled by the neck receiving portion of the closed mold; andinflating only the closed body of the preform into conformity with walls of the body receiving portion of the mold. 24. The method of claim 23 further comprising heating the preform, wherein the preform is rotated about a longitudinal axis of the preform by a spindle inserted into an open end of the preform during said heating of the preform. 25. The method of claim 23, wherein the circumferential recess of the neck receiving portion of the mold conforms to the collar, and the neck cavity section of the neck receiving portion of the mold conforms to the portion of the neck of the preform located within the neck receiving portion.
