A container made of thermoplastic material, including a body that extends between a neck and a base that is able to withstand, without significantly deforming, a hydrostatic pressure caused by the column of a liquid contained in the container, the column of liquid being increased by a pressure not exceeding 2×105 Pa. The base includes main ribs in the form of grooves that are open towards the outside and extend approximately radially, passing through an annular zone that forms an approximately flat seat by way of which the base can rest in a stable manner on a flat support. The main ribs extend upwards on a wall connecting the base to the body of the container. The container has a shoulder that forms a joining zone between the connecting wall and the body of the container, and the main ribs extend upwards beyond the shoulder.

1. Container made of thermoplastic material, comprising a body connected to a base able to withstand, without noticeable deformation, a hydrostatic pressure caused by a column of liquid contained in said container, said column of liquid being increased by a pressure not exceeding 2×105 Pa, said base
1. Container made of thermoplastic material, comprising a body connected to a base able to withstand, without noticeable deformation, a hydrostatic pressure caused by a column of liquid contained in said container, said column of liquid being increased by a pressure not exceeding 2×105 Pa, said base comprising main ribs in the form of grooves that are open towards the outside and extend substantially radially through an annular zone forming a substantially flat seat allowing said base to rest in a stable manner on a flat support, said main ribs being distributed in a star arrangement on the base and extending up a wall connecting the base to the body of the container, said container comprising a shoulder forming a connecting area between said connecting wall and the body of the container, wherein said main ribs extend upwards beyond said shoulder on the connecting wall,wherein said main ribs have a constant depth across a dome. 2. Container according to claim 1, wherein said base comprises: a concave dome with its concavity facing towards the outside of the container, andan inward bulge in the container, its concavity facing towards the outside, opening at the center of said dome,said main ribs extending radially on said dome from the seat to the bulge. 3. Container according to claim 2, wherein said base comprises secondary ribs which are radial and are sandwiched between said main ribs, and which extend radially in a star arrangement on the connecting wall and across the seat to approximately the beginning of the dome. 4. Container according to claim 3, wherein said secondary ribs extend across said connecting wall and beyond said shoulder, to a level substantially identical to that of said main ribs. 5. Container according to claim 3, wherein the base comprises a number of said main ribs, which are uniformly distributed, and a same number of said secondary ribs, which are uniformly distributed, and which are each sandwiched between two adjacent main ribs. 6. Container according to claim 5, wherein the base comprises between six to twelve uniformly distributed main ribs and between six to twelve secondary ribs each sandwiched between two main ribs. 7. Container according to claim 3, wherein the base comprises a number of said main ribs, which are uniformly distributed, and a same number of identical uniformly distributed sets of said secondary ribs each sandwiched between two adjacent main ribs. 8. Container according to claim 7, wherein the base comprises four uniformly distributed main ribs and four sets of three secondary ribs with each set sandwiched between two consecutive main ribs. 9. Container according to claim 7, wherein the base comprises five uniformly distributed main ribs and five sets of two secondary ribs with each set sandwiched between two consecutive main ribs. 10. Container according to claim 3, wherein the secondary ribs have a regular depth on the connecting wall, between the seat and the shoulder. 11. Container according to claim 3, wherein said main ribs have a depth which decreases between the seat and the shoulder. 12. Container according to claim 2, wherein each of said main ribs has, in the vicinity of the bulge, a flaring end such that a flaring end of each respective main rib meets a flaring end of an adjacent main rib, with the flaring ends forming a sunburst pattern around the bulge. 13. Container according to claim 12, wherein the main ribs flare out in a regular arrangement on the dome, from the seat to the vicinity of the bulge. 14. Container according to claim 1, wherein said main ribs extend beyond said shoulder onto the body of the container, to a height of substantially between 1 and 5 mm. 15. Container according to claim 1, said container comprising a container capacity which is 0.5 L and comprising a weight which is substantially 7 g.
