The invention relates to a method for manufacturing a container by stretch blow-molding from a preform made of plastic material in a forming unit, the forming unit comprising a mold, an elongation rod that is movable heightwise inside the mold, the method comprising, in succession, a pre-blow-molding step and a blow-molding step, the method also comprising a step of boxing of a handle, a rising phase of the elongation rod being initiated before the blow-molding step, the boxing step being initiated after the rising of the elongation rod, the handle being formed on the extension axis of the elongation rod.

Method for manufacturing a plastic container equipped with a handle obtained using boxing technique

A Molding unit for the forming of a container includes: a mold provided with a side wall defining a cavity bearing the impression of a portion of the container; an insert having a frontal surface bearing the impression of a local portion of the container, movable between a retracted position and a deployed position, with this insert being penetrated by ducts; a pierced piston to which the insert is attached and which ensures the mobility of the latter between its retracted position and its deployed position; and at least one pierced screw by which the insert is attached to the piston.

Molding unit equipped with a movable boxing insert ventilated by a fluid circuit tapped from the boxing fluid circuit

A container () made of plastic material, provided with an oblate body () and with a bottom () in the extension of the body () at a lower end thereof, the bottom () including: a peripheral base () defining an annular standing plane () whose contour exhibits, along a long axis, a large dimension A, and, along a short axis perpendicular to the long axis, a small dimension A' that is strictly smaller than the large dimension, a concave arch () that extends from the base () to a central area (); wherein the base has:  

Flattened container having an arched bottom with a variable-width base

A mould () for producing, from a blank (), a container () having a bottom () provided with a seat (), the mould () including: &#x2014;a wall () delimiting a cavity () and, beyond the cavity (), a hollow recess () opening into the cavity () via an opening (); &#x2014;a mould bottom () that is movable relative to the wall (), the bottom having an upper surface () defining a seat surface () having the footprint of the seat () of the container (). In this mould: &#x2014;the wall () has a counterbore () that defines, at the top, the hollow recess () and that extends perpendicular to and around the opening (), substantially parallel to the central axis (X); &#x2014;the upper surface () defines a peripheral face () that extends flush with the counterbore ().
