A plastic bottle, wherein reinforcing portions are formed by a circular groove provided around the body of the bottle. The groove comprises, from the base upwards, a lower part to be connected to the body, a central part, and an upper part to be connected to the body. Each of the parts has a constant peripheral profile, the central part having a peripheral profile with simple curvature with a concave part facing outwards of the bottle, the upper and lower parts having each a profile with simple curvature and a concave part facing inwards of the bottle, and the upper and lower parts are each connected tangentially to the body and the central part. The invention is particularly applicable to bottles designed to be filled with carbonated or aerated drinks.

1. A plastic bottle comprising: a body (10) that is cylindrical as generated by rotation, between the bottom (20) of the bottle and a shoulder area (30), and provided with reinforcing means (50) composed of a groove made around the body of the bottle, said groove having--from bottom to top--a low
1. A plastic bottle comprising: a body (10) that is cylindrical as generated by rotation, between the bottom (20) of the bottle and a shoulder area (30), and provided with reinforcing means (50) composed of a groove made around the body of the bottle, said groove having--from bottom to top--a lower part (51) for connection to the body, a central part (52), and an upper part (53) for connection to the body, each of these parts having a peripheral profile of a constant simple curve, the central part (52) having a peripheral profile with a concavity turned toward the outside of the bottle, the lower (51) and upper (53) parts each having a profile with a concavity turned toward the inside of the bottle, wherein the lower part (51), the central part (52) and the upper part (53) of the groove each have a constant curvature (R51, R52, R53), thus a segmental profile, and wherein the upper and lower parts are each connected tangentially to the body (10) and to the central part (52). 2. The bottle according to claim 1, wherein the dimensions of the reinforcing means (50) are such that in addition to their reinforcing function, they offer a grip function for the bottle. 3. The bottle according to claim 2, wherein the overall height of the reinforcing means (50) is between 60 mm and 100 mm. 4. The bottle according to claim 1, wherein the reinforcing means are disposed in the upper part of the body. 5. The bottle according to claim 4, wherein the reinforcing means (50) are placed at or slightly above the bottle's center of gravity. 6. The bottle according to claim 1, wherein the diameter at the bottom of the groove, that is, at the bottom of the central part (52), has a value of between 50% and 80% of the maximum diameter of the rest of the body of the bottle. 7. The bottle according to claim 6, wherein the diameter at the bottom of the groove has a value of between 60% and 70% of the maximum diameter of the rest of the body of the bottle. 8. The bottle according to claim 1, wherein the lower part (51) and/or the upper part (53) of the groove have a curvature with an average radius of curvature the value of which is between 35% and 55% of the radius of the body of the bottle. 9. The bottle according to claim 8, wherein at least one of the lower part (51) and the upper part (53) of the groove has a curvature with an average radius of curvature the value of which is on the order of 40% of the radius of the body of the bottle. 10. The bottle according to claim 1, wherein the lower part (51) and the upper part (53) of the groove have an identical curvature. 11. The bottle according to claim 1, wherein it is obtained by the injection, heat conditioning, then blow-molding, or alternatively drawing, then blow-molding, of a plastic preform.
