Abstract
The invention concerns a preform () for forming a bottle for gaseous beverage, the preform comprising a multilayered wall obtained by injection in a mould from an injecting point () located at a central bottom end of the preform, the multilayered wall including an inner layer (), an outer layer () and a gasbarrier layer () sandwiched between the inner and outer layer. The gas barrier layer () advantageously extends along the entire preform multilayered wall except for a bottom ending portion (), this bottom ending portion free of barrier layer () being a central part of a base-forming portion () delimited by a solid angle (α) comprised between 5° to 80°, the apex (C) of this solid angle being the centre of a semi-spherical lower segment of the base-forming portion (). A bottle obtained by blow-moulding such a preform has a bottom ending portion free of barrier layer within a solid angle comprised between 5° and 50°.
