A preform is disclosed for the production of plastic containers, for example plastic bottles, in a stretch-blow-molding method. The preform can include an elongated preform body having a closed longitudinal end and which connects on an opposite longitudinal end to a neck section having a pour opening, the neck section having an outside wall with a fastening means. A rotating flange at a transition from the preform body to the neck section, wherein at least a portion of the rotating flange is annular and radially extends above an outside wall of the preform body. A peripheral annular groove can extend obliquely from a base of the annular groove to the outside wall of the neck section forming a circumferential inner collar, and wherein the inner collar the direction of the preform body, extends axially above the annular groove and extends into an inside wall of the preform body. |
