Abstract
The invention concerns a bottle (1) molded from at least one thermoplastic polymer of at least one Furan Dicarboxylic Acid (FDCA) monomer, preferably 2,5-Furan Dicarboxylic Acid (2,5-FDCA) monomer, and at least one diol monomer, preferably Monoethyleneglycol (MEG) monomer, said bottle, having a main axis (X), being provided with a body (5) and a bottom base (6) extending from a lower end of the body (5). The bottom base (6) comprises:—a peripheral seat (7) defining a laying plane (8);—a concave arch (10) which extends from the periphery of a central zone (11) of the bottom base (6) to the peripheral seat (7), said concave arch (10) having a rounded general shape with a concavity turned towards the outside of the container (1) and the middle point of the central zone (11) being named push-up (11a);—a series of reinforcing grooves (13) which extend radially from the central zone (11) to at least the peripheral seat (7);—base feet (14) located between two adjacent reinforcing grooves (13); According to the invention, the bottle bottom base (6) comprises an offset sitting radius, defined as the distance between the maximum bottle diameter and the contact point of the base feet with the…
