Abstract: A mold for blow molding a container from a preform, the container including a wall portion and a base including a high standing ring and a central outwardly-inclined invertible diaphragm, the mold including sidewalls forming a counter print of the wall portion of the container (1) and a mold base (36) having an upper surface (37) defining a counter print of the container base, wherein the upper surface (37) includes: an annular peripheral face (43) corresponding to an annular support flange of the container base; a frusto-conical outer face (44) corresponding to an inner portion (11) of the high standing ring, the outer face (44) protruding upwardly with a draft angle (A2) from an inner edge of the peripheral annular face (43) up to a sharp apex (45), and a frusto-conical downwardly inclined inner face (46) corresponding to the invertible diaphragm.

Abstract: Disclosed is a preform for a plastics container, which includes: a rotationally symmetrical body about a central axis; an open neck which extends in continuation of the body from an upper end of the latter; a bottom which closes the body starting from a lower end of the latter, the bottom being rotationally symmetrical about the central axis and having a central concavity and a protruding bulge around this concavity, the bottom having a thickness E, measured from an external face, that is variable in accordance with three different criteria respectively applied to three sections of the bottom, namely a central section [0; S1], an intermediate section [S1; S2] and a peripheral section [S2; L].

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.
