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 a push-up height, defined as the height between the push-up (11a) and the laying plan (8), that is in the range of 7 to 10 mm for…
