A container (1) made from thermoplastic material obtained by blow moulding, or stretch-blow moulding, includes a body (2) and a petaloid bottom (5) that has a central area (7) from which feet (6) extend radially, alternating with valleys (10), each foot (6) including a peripheral portion (11) connected to the body (2) of the container and a central portion (12) connected to the central area (7), the container being characterized in that each foot further has a truncated portion (13) forming a seat for the container (1), extending between the peripheral portion (11) and the central portion (12). |

1. Container (1) made of thermoplastic material that is obtained by blow molding or stretch blow molding of a previously-injected preform, with the container (1) comprising a body (2) extending along a main axis (X) and comprising a petaloid-type bottom (5) that has a central zone (7) from which feet (6) alternating with valleys (10) extend radially, with each foot (6) comprising a peripheral portion (11) connected to the body (2) of the container and a central portion (12) connected to the central zone (7), wherein each foot also has a truncated portion (13), forming a seat for the container (1) and extending between the peripheral portion (11) and the central portion (12), the truncated portion (13) comprising a first surface (14) for connecting to the peripheral portion, a second surface (15) for connecting to the central portion, and an intermediate surface (16) connecting the first and second surfaces (14, 15), the intermediate surface (16) being defined by the rotation of at least one generatrix curve (C3) around a truncation axis (T) that is different from the main axis (X) and specific to each foot, the radius (R3) of curvature of the curve (C3) of the intermediate surface (16) being larger than the radius (R1, R2) of curvature of generatrix curves (C1, C2) of the first and second surfaces (14, 15). |
