Abstract
A container, especially a bottle, is made from a preform of polyethylene terephthalate (PET), where the preform has a mouth portion, a substantially conical upper portion extending from the mouth portion, and a cylindrical portion extending from the conical portion towards the bottom of the preform and having a substantially uniform wall thickness. When reshaping the preform, the shoulder of the container is formed substantially only of material which in the preform is located in the conical upper portion of the preform, while the cylindrical portion of the container is formed substantially only of material which in the preform is located in the cylindrical portion of the preform. The expansion of the material in the conical portion of the preform and of the material in the cylindrical portion of the preform is selectively controlled in such a manner that the material in the respective portion undergoes stretching in the axial direction of the preform, defined by the quotient of the axial length of the conical portion of the preform and the axial length of the cylindrical portion of the preform having values in the range 0.25-0.35, and by the quotient of the axial length of the shoulder and the axial length of the cylindrical portion of the container having values in the range 0.60-0.80.
