Abstract
A method for the fabrication of a container (802), comprising the steps of: —providing a preform (705), said preform being substantially tubular in form and being provided with a closed end (709), a cavity (707), and an open end (710) communicating with said cavity (707); —positioning at least one restriction device (711, 714) relative to the preform (705) so as to define at least one restriction zone and restrict expansion of the preform (705) therein; —injecting a pre-determined volume of an incompressible fluid (800) into the cavity (707) of the preform (705) via the open end (710), provoking the preform (705) to plastically deform by expansion, said preform (705) expanding freely in at least one expansion zone outside said at least one restriction zone; and —Using for the fabrication of a beverage container (802).
