摘要： Method of manufacturing a container from a blank of plastic material, within a mold provided with a wall defining a cavity with the impression of the container, and a mold bottom that is movable with respect to the wall between a retracted position and a deployed position in which it extends protruding into the interior of the cavity in order to form a hollow recess in the container. The method includes inserting the blank into the mold; a pre-blowing operation including injecting a fluid under pressure into the blank, at a pre-blowing pressure; a blowing operation including injecting a fluid under pressure into the blank at a blowing pressure that is greater than the pre-blowing pressure; and a boxing operation, initiated prior to the blowing operation, and including moving the movable mold bottom from its retracted position to its deployed position.

摘要： A method of manufacturing a container from a blank in a stretch blowing assembly equipped with a mold provided with a wall and a mold bottom axially movable between an extended position and a retracted position and a stretch unit having a rod axially movable with respect to the wall and a device for controlling the movement of the rod. The method involves a stretch blowing phase; a boxing phase during which the mold bottom, initially in the extended position, is moved towards its retracted position, the boxing phase having a retraction operation including controlling a movement of the rod in synchronization with the movement of the mold bottom, or releasing the rod to allow the free axial movement thereof.

摘要： A container, in particular a bottle, made of thermoplastic material produced by blow molding or stretch-blow molding of a heated preform, the container designed to contain a liquid being flat and having a substantially domed base with outward-facing cavity defining a substantially planar peripheral annular seat for being set on a support, the base being provided with several grooves radiating from the base center. Each groove in its zone of intersection with the annular seat, has a portion of substantially increased width and the two edges of that portion of the groove are curved with relatively large radii of curvature and with respective concavities facing one another.
