Abstract
Thermoplastic container having a body and a base including: a concave arch, a concave dome opening at the center of the arch, an annular zone surrounding the base of the arch and forming a flat foundation, claw-shaped zones radially extending the base of the body and offset projecting outwards relative to the arch, and radial grooves delimited between the zones in the shape of claws. The grooves have bottoms that are formed by radial sections of the arch and that have a radially variable depth maximum in correspondence with said annular zone forming a foundation. The base is adapted for withstanding, without marked deformation, hydrostatic pressure due to the liquid column increased by an excess pressure not exceeding approximately 2×105 Pa.
