Disclosed is a container perform made from plastic material, including: a body; an open neck that extends from the body from which it is separated by a radially projecting flange; a bottom that closes the body opposite the neck; the body having a concave portion in axial cross section, where: B≤0.9.Math.A 0.5.C≤C′≤0.95.C in which A is the overall diameter of the body, measured below the flange; B is the outer diameter of the bottom, measured at the junction of same with the body; C is the cumulative height of the body and the bottom, measured from the flange; C′ is the height, measured axially, of the concave portion of the body, and the concave portion has, in axial cross-section, on an outer surface, an outer radius of curvature RE such that: 1.5.0≤RE≤10.C

A preform configured to be blow-molded into a plastic bottle includes a neck section defining an opening, the neck section including a threaded portion configured to engage a closure, and a neck ring, a transition section having a first end positioned adjacent to the neck ring and a second end opposite the first end, a cylindrical body section extending from the second end of the transition section to a base, and a longitudinal axis extending from the opening through the base. The neck section, transition section, and the body section define a hollow channel positioned between the opening and the base. The transition section defines a tapered sidewall relative to the longitudinal axis, the tapered sidewall decreases a cross-sectional diameter of the hollow channel. The tapered sidewall of the transition section contains 20% to 30% of a total weight of the preform.

The invention relates to a preform for producing a plastic container in a 2-stage stretch blow molding method, said preform having a preform body that extends along a central axis and that comprises: a first end a second end that lies opposite the first end, wherein the first end is closed and a neck part with a pouring opening adjoins the second end; and an inner wall that delimits an interior of the preform. Along a length of at least 30 mm of the interior, every point of the inner wall is at a distance of less than 3.5 mm from the central axis. Also disclosed are a suitable method and a device for producing such a preform.
