Abstract: A conditioning assembly for conditioning an article (D), such as a fluid dispenser, under vacuum, the assembly including an airtight enclosure (E) for receiving an article (D) for conditioning under a vacuum; the assembly being characterized in that the enclosure (E) includes a conditioning element (21) that is movable inside the enclosure, the enclosure (E) being connected to a suction chamber (C) that includes a piston (22) that is capable of causing the volume of the chamber (C) to vary, the conditioning element (21) and the piston (22) being constrained to move together in a manner such that a movement of the piston (22) in the direction for increasing the volume of the chamber (C) causes suction to be generated in the enclosure (E).

Abstract: A method of molding by injecting plastics material into a mold to make a part that is symmetrical about an axis of revolution, the part being hollow with a through passage along the axis, the part having two axial ends each defining an annular opening, the method comprising injecting the plastics material into the mold via an annular opening in an axial end of the part along an annular injection line, the plastics material containing solid particles of the flake or pearlescent type, thereby imparting flake and/or pearlescent highlights to the molded part.
