Abstract: A bottle made of plastic material having a body extending along a central axis which comprises: a lower portion having a cross section with an essentially constant profile, followed by a gripping portion, and ending in an upper portion having a section with an essentially constant profile arranged in alignment with the profile of the section of the lower portion. The gripping portion comprises two globally plane gripping panels arranged parallel to one another and in relation to the central axis at a distance which is adapted for a hand taking. These panels have at least one reinforcing relief which extends in a transverse plane and are interconnected by connecting panels extending in continuation of the lower and upper portions by means of rounded corners located at the circumferential ends of the panels.
