A thermoplastic container, such as a bottle, obtained by extrusion-blow or injection-blow molding and having a petaloid base (6, 7). The base includes a convex wall (7) hemispherical in shape; the wall (7) is linked to the wall (2) forming the container body by a marginal zone (8) with a curve (R1, R 2). Members (6) originate from the hemispherical wall (7 ) and are separated in pairs by a part thereof; the top end of each member is directly linked to the wall (2) forming the body.

What is claimed is: 1. A monolithic container (1) with a substantially cylindrical wall (2) and a petaloid-shaped base (6,7) which extends from the substantially cylindrical wall, said base comprising a wall that is shaped substantially convexly towards an outside of the container, wherein at least three members (6) originate from the substantially cylindrical wall and are formed by outgrowths that are regularly distributed and separated in pairs by a portion of the convex base wall (7), wherein: the base wall (7) is hemispherical, except for a peripheral marginal linking area (8) with the cylindrical wall, said peripheral marginal linking area (8) has a curve (R1; R2) with an inflection (9) so that the base wall and the peripheral marginal linking area as well as the cylindrical wall and the peripheral marginal linking area are linked in an almost tangential manner, and a top end of each member is connected with the cylindrical wall (2), wherein said inflection (9) is a change in curvature of said curve (R1; R2) from a concave curve to a convex curve. 2. A container according to claim 1, wherein the members ( 6) are linked with the hemispherical wall (7), in the direction of a central pole (10) of the hemispherical wall ( 7), in a roughly tangential manner. 3. A container according to claim 1, wherein the members ( 6) are linked with the hemispherical wall (7), in the direction of a central pole (10) of the hemispherical wall ( 7), in immediate proximity of the hemispherical wall (7). 4. A one-piece blow molded plastic container (1) with a substantially cylindrical wall (2) and a petaloid-shaped base (6,7) which extends from the substantially cylindrical wall, said base comprising a wall that is shaped substantially convexly towards an outside of the container, wherein at least three members (6) originate from the substantially cylindrical wall and are formed by outgrowths that are regularly distributed and separated in pairs by a portion of the convex base wall (7), wherein: the base wall (7) is hemispherical, except for a peripheral marginal linking area (8) with the cylindrical wall, said peripheral marginal linking area (8) has a curve (R1; R2) with an inflection (9) so that the base wall and the peripheral marginal linking area as well as the cylindrical wall and the peripheral marginal linking area are linked in an almost tangential manner, and a top end of each member is connected with the cylindrical wall (2), wherein said inflection (9) is a change in curvature of said curve (R1; R2) from a concave curve to a convex curve; and wherein the curve radius (R) of the hemispherical wall ( 7) is between 80% and 120% of the radius of the cylindrical wall ( 2). 5. A container according to claim 1, wherein a clearance is provided between a central pole (10) of the hemispherical part and a supporting surface (11) of each member (6). 6. A container according to claim 1, wherein the top end of the members (6) is linked with the cylindrical wall (2) in a substantially tangential manner. 7. A container according to claim 1, further comprising a shoulder (3), a collar (4), a neck (5), and means for closing the container by means of a suitable device. 8. The container according to claim 4, wherein the members (6) are linked with the hemispherical wall (7), in the direction of a central pole (10) of the hemispherical wall ( 7), in a roughly tangential manner. 9. The container according to claim 4, wherein the members (6) are linked with the hemispherical wall (7), in the direction of a central pole (10) of the hemispherical wall ( 7), in immediate proximity of the hemispherical wall (7). 10. The container according to claim 4, wherein a clearance is provided between a central pole (10) of the hemispherical part and a supporting surface (11) of each member (6). 11. The container according to claim 4, wherein the top end of the members (6) is linked with the cylindrical wall (2) in a substantially tangential manner. 12. The container according to claim 4, further comprising a shoulder (3), a collar (4), a neck (5), and means for closing the container by means of a suitable device.
