Bottle, method of making the same and use of FDCA and diol monomers in such bottle
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 ( 11 a );—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 laying plan ( 8 ) that is in the range of 5 to 10 mm for a bottle having a diameter (D) between 40 and 150 mm.
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 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, in the range of 5 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 , 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 claim 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 (FDCA) 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 an offset sitting radius, in the range of 5 to 10 mm for a bottle having a diameter 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.
