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 a bottle having a diameter (D) between 40 and 150 mm.

First claim

The invention claimed is:

1. A bottle molded from at least one thermoplastic polymer of at least one Furan Dicarboxylic Acid (FDCA) monomer, and at least one diol monomer, the bottle, having a main axis, being provided with a body and a bottom base extending from a lower end of the body, the bottom base comprising:
a peripheral seat defining a laying plane;
a concave arch which extends from the periphery of a central zone of the bottom base to the peripheral seat, the 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;
a series of reinforcing grooves which extend radially from the central zone to at least the peripheral seat;
base feet located between two adjacent reinforcing grooves; and
the bottle bottom base comprises a push-up height, defined as the height between the push-up and the laying plan, is in the range of 7 to 10 mm for a bottle having a diameter between 40 and 150 mm.

2. A bottle according to claim 1 comprising a number of reinforcing grooves from 5 to 10.

3. A bottle according to claim 1 , in which the reinforcing grooves have a groove radius comprised within the range from 1 to 6 mm.

4. A bottle according to claim 1 , further comprising from 5 to 10 base feet.

5. A bottle according to claim 1 , in which the radius of the base feet at their contact point with the laying plan is from 1 to 8 mm.

6. A bottle according to claim 1 , having an internal volume between 15 to 350 cl.

7. A bottle according to 1 , being filled with a pressurized liquid.

8. A bottle according to claim 7 , in which the beverage is a carbonated beverage or a beverage bottled under nitrogen atmosphere.

9. A method of making a bottle comprising the steps of:
providing a preform made of at least one thermoplastic polymer of at least one Furan Dicarboxylic Acid monomer, and at least one diol monomer;
placing the preform in a mold having a cavity comprising at least one imprinting member; and
blowing the preform in the mold to form the bottle comprising a push-up having a push-up height in the range of 7 to 10 mm for a bottle having a having a diameter ED) between 40 and 150 mm.

10. A method according to claim 9 , wherein at the step of providing a preform, the preform comprises a hollow tube extending along a longitudinal axis and having a closed bottom end and an opened top end, the step of blowing the preform comprising blowing the preform through the opened top end at a blowing pressure less than or equal to 35 bars.

11. A method according to claim 9 , further comprising a step of filling the bottle with a liquid.
