Claim Text:
1. A plastic container preform comprising a base body formed of a single material, a closure region including a threaded region having a minimum diameter and a thread extending outwardly from a minimum diameter surface, and an at least partially circumferential securing ring which extends outwards relative to the base body of the container, wherein the circumferential securing ring is arranged between the thread and the base body in a longitudinal direction (L) of the preform and is spaced apart from the thread in the longitudinal direction (L) of the preform, wherein the preform comprises an at least partially circumferential groove between one portion of the minimum diameter surface and portions of the minimum diameter surface extending to either side of the thread and the circumferential securing ring, wherein a side wall of the securing ring forms a boundary wall of the circumferential groove, wherein the circumferential groove has a minimum diameter less than the securing ring and less than said one portion of the minimum diameter surface, wherein the preform has a constant interior diameter adjacent a level of the thread, wherein an internal diameter of the container preform is reduced at a level of the circumferential groove and at the level of the circumferential securing ring, wherein the preform interior wall has below the circumferential securing ring a section that has a constant diameter, wherein the thread is an outer thread, wherein the base body has an internal diameter which widens at a point adjacent the circumferential groove as one progresses longitudinally upward from the circumferential securing ring, and wherein, besides the securing ring, no further ring exists between the thread and the securing ring.
