ABSTRACT OF THE DISCLOSURE A pressure-resistant thermoplastic bottle has a low center of gravity and a dimensionally stable seating ring zone of substantial strength. The center of gravity is lowered by reducing the weight of the finish and neck, and using a larger diameter for the main body to reduce the overall height while maintaining the desired internal volume. The improved design of the seating ring results in a thicker wall in the bottom end and, therefore, a stronger structure. The bottom end includes a sharp V-shaped structure having a concave in- side wall and a generally convex outside wall joined at the bottom ends by a lower end portion which is concave at its outer surface. A convex central portion is connected to an upper end of the inner wall to define a central cavity and an extreme lower end of the outer wall is generally concave.
