Method of making a container having an elongated body equipped with a neck, such as a bottle (2), from a preform (1) made of thermoplastic polymer, said bottle (2) having special dimensional parameters. It essentially comprises a step of stretching and blowing a thin- walled (10) preform (I) with an average thickness (e) of its wall (10) less than 2 mm and an aspect ratio u = l/e, l being the length of the thin-walled preform (1), superior to 45. A thin-walled preform and a bottle are also claimed.
