A container () made of plastic having a main axis (X) being provided with a body () and a bottom base () extending from a lower end of the body (), the bottom base () comprising: &#x22c5;&#x2014;a peripheral seat () defining a laying plane (); &#x22c5;&#x2014;a concave arch () which extends from the periphery of a central zone () of the bottom base () to the peripheral seat (), said concave arch () having a rounded general shape with a concavity turned towards the outside of the container (); &#x22c5;&#x2014;a series of principal reinforcing grooves () which extend radially from the central zone () to at least the peripheral seat (). The concave arch () has two annularly tangentially continuous concentric regions, i.e. a central region () and a peripheral region (), said annularly tangentially concentric regions being in continuity with each other and presenting two different radius of curvature, the peripheral region () having a radius of curvature smaller than the one of the central region ().

Container bottom base provided with a bi-concave arch

The invention concerns a bottle () 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 () and a bottom base () extending from a lower end of the body (). The bottom base () comprises:&#x2014;a peripheral seat () defining a laying plane ();&#x2014;a concave arch () which extends from the periphery of a central zone () of the bottom base () to the peripheral seat (), said concave arch () having a rounded general shape with a concavity turned towards the outside of the container () and the middle point of the central zone () being named push-up ();&#x2014;a series of reinforcing grooves () which extend radially from the central zone () to at least the peripheral seat ();&#x2014;base feet () located between two adjacent reinforcing grooves (); According to the invention, the bottle bottom base () comprises an offset sitting radius, defined as the distance between the maximum bottle diameter and the contact point of the base feet with the laying plan () that is in the range of 5 to 10 mm for a bottle having a diameter (D) between 40 and 150 mm.
