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.
