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
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 preform including a closed body, a neck located between the closed body and an open end, and an outwardly extending collar and thread formation each located along the neck, wherein the thread formation is located between the open
1. A method for making a container, the method comprising: providing a preform including a closed body, a neck located between the closed body and an open end, and an outwardly extending collar and thread formation each located along the neck, wherein the thread formation is located between the open end and the collar;providing a mold having a coextensive body receiving portion and neck receiving portion, wherein the neck receiving portion includes a circumferential recess extending upwardly from the body receiving portion and a neck cavity extending upwardly from the circumferential recess;closing the mold about the preform while an exterior of the neck is held by a gripper so that the closed body of the preform is received within the body receiving portion of the closed mold, the thread formation is located outside of the neck receiving portion of the closed mold, and a first portion of the neck extending upwardly from the collar is engaged within the neck cavity of the closed mold, wherein the collar of the preform is engaged and seated within the circumferential recess of the neck receiving portion of the closed mold and the width of the neck cavity and circumferential recess of the closed mold are substantially the same as the width of the first neck portion and collar, respectively, so as to restrict vertical movement of the preform relative to the closed mold; andblowing 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, wherein the collar has a height, the circumferential recess has a height, and the height of the collar is substantially the same as the height of the circumferential recess. 3. The method of claim 1, further comprising heating the preform prior to said closing. 4. The method of the 3, further comprising rotating the preform about a longitudinal axis of the preform during said heating of the preform. 5. The method of claim 1, wherein the gripper conducts said holding between a pair of axially spaced rings of the neck during said closing of the mold. 6. The method of claim 1, wherein the gripper contacts an outer surface of the mold during said closing. 7. The method of claim 1, wherein the blowing is conducted such that only the closed body portion of the preform is blown into conformity with the walls of the body receiving portion of the closed mold. 8. A method for making a container, the method comprising: providing a preform including a closed body, a neck located between the closed body and an open end, an outwardly extending first collar located at a first position along the neck, and an outwardly extending second collar located at a second position along the neck, the first collar located between the closed body and the second collar;providing a mold having a coextensive body receiving portion and neck receiving portion, the neck receiving portion including a circumferential recess and a neck cavity each having a height, the circumferential recess extending upwardly from the body receiving portion, the neck cavity extending upwardly from the circumferential recess, and the height of the neck cavity generally corresponding to the distance between the first and second positions;closing the mold about the preform while an exterior of the neck is held by a gripper such that the closed body of the preform is received with the body receiving portion of the closed mold, a first portion of the neck extending upwardly from the first collar is engaged within the neck cavity of the closed mold, and the first collar is seated in the circumferential recess of the neck receiving portion of the closed mold, wherein a width of the neck cavity and circumferential recess of the closed mold are substantially the same as the width of the first neck portion and collar, respectively; andinflating the closed body of preform into conformity with walls of the body receiving portion of the closed mold. 9. The method of claim 8, further comprising heating the preform prior to said closing. 10. The method of the 9, further comprising rotating the preform about a longitudinal axis of the preform during said heating of the preform. 11. The method of claim 10, wherein said rotating is conducted by a spindle inserted into the open end of the preform. 12. The method of claim 8, wherein the gripper conducts said holding between a pair of axially spaced rings of the second collar during said closing of the mold. 13. The method of claim 8, wherein said inflating is conducted such that only the closed body of the preform is inflated. 14. A method for making a container from a preform, the method comprising: providing a preform including a closed body, a neck located between the closed body and an open end, and a first and second outwardly extending collar, the first collar located between the closed body and the second collar;providing a mold having a coextensive body receiving portion and neck receiving portion, the neck receiving portion including a circumferential recess extending upwardly from the body receiving portion, a neck cavity extending upwardly from the circumferential recess, and a circumferential seat, the neck cavity located between the circumferential recess and the circumferential seat;closing the mold about the preform while an exterior of the neck is held by a gripper such that the closed body of the preform is received with the body receiving portion of the closed mold, a first portion of the neck extending upwardly from the collar is engaged within the neck cavity of the closed mold, and the first collar is seated in the circumferential recess of the neck receiving portion of the closed mold, wherein the width of the neck cavity of the closed mold is less than the width of each of the circumferential seat and the circumferential recess of the closed mold, and wherein the width of the neck cavity and circumferential recess of the closed mold are substantially the same as the width of the first neck portion and collar, respectively; andinflating the closed body of preform into conformity with walls of the body receiving portion of the closed mold. 15. The method of claim 14, wherein the second collar is seated on the circumferential seat of the closed mold. 16. The method of claim 14, wherein said inflating is conducted such that only the closed body of the preform is inflated into conformity with the walls of the body receiving portion of the mold. 17. The method of claim 14, further comprising heating the preform prior to said closing. 18. The method of the 17, further comprising rotating the preform about a longitudinal axis of the preform during said heating of the preform. 19. The method of claim 14, wherein the gripper conducts said holding between a pair of axially spaced rings of the second collar during said closing of the mold. 20. The method of claim 14, wherein the gripper contacts an outer surface of the mold during said closing.
