A plastic bottle includes: a body which extends longitudinally along a central axis from the neck to the lower end thereof and which has a pre-determined thickness, and a base (2) including an apron (3) which is connected to the lower end of the body and which extends to a peripheral bearing area. In addition, a dome (7) extends from the peripheral bearing area to the apex (7a) located essentially on the central axis and grooves (9) extend radially between the apron and the dome, the grooves having a base line (9a). The direction of the base lines (9a) of the grooves forms a sharp angle with the direction tangential to the dome (7) at the point (9d) at which the base of the grooves (9) opens into the dome (7).

1. A plastic bottle comprising a body extending longitudinally on a central axis from a neck to a lower end and having a predetermined thickness, and a base, said base comprising: feet having, in a radial section, a rounded profile;a skirt connected to said lower end of the body and extending to a peripheral bearing zone;a dome with a concavity oriented outward, the dome extending from said peripheral bearing zone to an apex situated substantially on the central axis, the dome having an outer face and a height measured on said outer face, the apex of the doame comprising a hollow nipple with a concavity oriented outward, the dome being continuously rounded below the apex; andgrooves having a bottom and extending radially between said skirt and said dome, the grooves having a longitudinal bottom line extending over the bottom of said grooves in their direction of radial extension, said bottom line extending at a distance from the peripheral bearing zone,wherein said base of the plastic bottle is a champagne base,wherein the grooves are each connected to the dome via a connection profile, said bottom line of the grooves has a direction forming a pronounced angle with the direction tangential to said dome at the outlet of the bottom of said grooves in the dome, the height of said grooves at said outlet being between 30 and 60% of said height of the dome, said outlet being distant from the hollow nipple, andwherein said angle is between 90 degrees and 120degrees. 2. The bottle as claimed in claim 1, wherein said angle is equal to 120 degrees. 3. The bottle as claimed in claim 1, wherein the dome has a top portion and a lower portion, said grooves emerging only in said lower portion of the dome, and wherein the lower portion of the dome has a thickness that is substantially equal to the predetermined thickness, while the top portion of the dome has a minimal thickness that is significantly greater than said predetermined thickness. 4. The bottle as claimed in claim 3, wherein said minimal thickness of the top portion of the dome is equal to at least twice the predetermined thickness. 5. The bottle as claimed in claim 4, wherein said minimal thickness is approximately equal to three times said predetermined thickness. 6. The bottle as claimed in claim 3, wherein, at a distance from the apex of the dome, the thickness of the top portion of the dome varies in a range from one to three times said minimal thickness. 7. The bottle as claimed in claim 1, wherein said apex of the dome comprises a hollow nipple with a concavity oriented outward. 8. The bottle as claimed in claim 1, wherein said height of said grooves is approximately 40%. 9. The bottle as claimed in claim 1, wherein said bearing zone comprises the feet, the feet extending circumferentially over a major portion of the periphery of the bearing zone. 10. A plastic bottle comprising a body extending longitudinally on a central axis from a neck to a lower end and having a predetermined thickness, and a base, said base comprising: feet having, in radial section, a rounded profile;a skirt connected to said lower end of the body and extending to a peripheral bearing zone;a dome with a concavity oriented outward, the dome extending from said peripheral bearing zone to an apex situated substantially on the central axis, the dome having an outer face and a height measured on said outer face, the apex of the dome comprising a hollow nipple with a concavity oriented outward, the dome being continuously rounded below the apex; andgrooves having a bottom and extending radially between said skirt and said dome, the grooves having a longitudinal bottom line extending over the bottom of said grooves in their direction of radial extension, said bottom line extending at a distance from the peripheral bearing zone,wherein said base of the plastic bottle is a champagne base,wherein the grooves are each connected to the dome via a connection profile, said bottom line of the grooves has a direction forming a pronounced angle with the direction tangential to said dome at the outlet of the bottom of said grooves in the dome, the height of said grooves at said outlet being between 30 and 60% of said height of the dome, said outlet being distant from the hollow nipple, andwherein said angle is more than 120 degrees and less than 150 degrees.
