Abstract: The invention relates to a container preform made of plastics material having a body exhibiting symmetry of revolution about a central axis and a bottom closing the body from one of its ends. The bottom having an annular bead forming a standing plane of the preform, and the bottom has an external skin oriented toward the outside of the preform and an internal skin oriented toward the inside of the preform. At least one of the internal skin and the external skin has, radially from the central axis as far as the annular bead, a profile having a break in curvature.

Abstract: The invention concerns a preform for a container made of plastic material, comprising a cylindrical body that extends along an axis of revolution of the preform and a bottom that closes the cylindrical body. The bottom has an outer profile with a central portion and a curved portion joining the central portion to the cylindrical body. The central portion has, in longitudinal cross-section, a first concave section. The curved portion has successively, in longitudinal cross-section, from the first concave section towards the cylindrical body, a first convex or frustoconical section, a second concave section and a second convex or frustoconical section.

Abstract: Disclosed is a mold for the manufacture, from a blank, of a container having a body and a base provided with a peripheral seat. The mold includes: a wall bearing the impression of the body of the container and provided with an opening; a mold base which is movable relative to the wall between an extended position and a retracted position; the mold base having a peripheral surface which corresponds to a join between the seat and the base of the container and terminates in an edge which is raised with respect to the seat surface. In the extended position of the mold base, the edge extends vertically perpendicular to the opening and, in the retracted position of the mold base, the edge extends near the opening.
