    • Process for forming containers from a blank, preferably a preform, made of a thermoplastic, the containers being formed using a stretch-blow moulding machine of rotary type comprising at least one blow-moulding mould mounted on the periphery of a carousel rotated continuously about its axis, the blow-moulding mould operating in cyclic manner according to a blow-moulding cycle comprising the following steps: a step of placing a preheated blank in a blow-moulding mould; a step of closing the blow-moulding mould; a step of blowing the blank in the blow-moulding mould; a step of flushing the inside of the container with a cooling gas, by injecting air thereinto; a step of grasping the blow-moulded container by external gripping means; and a step of opening the blow-moulding mould, which process consists in automatically varying the duration of said flushing step at each start of production of the containers, in a temporary and evolving manner for a few minutes, in order to establish, in said containers, thermal conditions enabling the first containers to be formed at a temperature that gives them a final volume corresponding to the final volume of the containers formed during the stead-state operation of said stretch-blow moulding machine.

    • The invention relates to a container (1) made of a plastic material and having a flat body (2) and a bottom (3) that forms an extension of the body (2), the bottom (3) including: a peripheral base (7) defining a positioning plane (8), the outline of which has, within the plane, a small dimension A2 and a large dimension A1 that is strictly greater than the small dimension, and an inner annular flange (10) that is substantially perpendicular to the positioning plane (8); and a concave arch (13) that extends from the base (7) to a central area (14). In said container: the height H of the flange (10) and the width L of the positioning plane (8) are such that 0.5 ≤ L/H ≤ 1.5; and a transverse extension A of the positioning plane (8) and a transverse extension B of the body (2), measured in the vicinity of the bottom (3), are such that A/B ≥ 0.85.
